'''"' - 2 1 4 4 1 4 8 Then, the secondary cell unit 16 which is one characteristic of the embodiment 2 will be described.
Fig. 8 is a diagram indicating a construction of the secondary cell unit 16. In Fig. 8, the secondary cell unit 16 is connected to the personal computer 2 through one part of terminals VCC, CD1, CD2 installed on the connector 14, and is connected to the antenna 13 through the portable telephone circuit 222.
The secondary cell unit 16 comprises a DC-DC
convertor 161 which is connected to the terminal VCC, a secondary cell 162, a comparator 163 consisting of the comparators 163a - 163c and an indicator -164 which is connected to the secondary cell 162 through each of the comparators and the resistances R2 - R4 corresponding to the comparator. The secondary cell 162 is connected to the DC-DC convertor 161 through the diode D1 and the resistor Rl, and is connected to the portable telephone circuit 222.
Further, a voltage stabilization circuit which sets the voltage transmitted from the personal computer 2 to the predetermined voltage can be used in place of the DC-DC convertor 161.
In the above-mentioned construction, as shown in Fig. 5, the personal computer 2 will connect the card diction terminals CD1 and CD2 on the JEIDA/PCMCIA
interface to the terminal GND, if the lower part body of equipment 12 is inserted into the IC card slot 31.
,r~ , Then, the personal computer 2 recognizes that an ordinary IC card is mounted when the lower part body of equipment 12 is inserted into the IC card slot 31, and supplies the terminal VCC with the electric power. The electric power is supplied to the secondary cell 162 through the DC-DC convertor 161 so that the secondary cell 162 will be charged.
Then, the portable telephone circuit 222 is actuated by the electric power supplied from the secondary cell 162, and the radio data communication is executed.
Besides, the charging voltage which is charged into the secondary cell 162 is compared with the threshold voltage which was set up previously in each of comparators 163a - 163c. The corresponding light-emitting diodes 164a - 164c installed on the indicator 164 are lighted up, when the charging voltage exceeds the threshold voltage.
Accordingly, the charging state of the secondary cell 162 can be recognized by the number of lightings of the light-emitting diode. Hereupon, the indicator 111 can be provided with the function mentioned above, even though the indicator 164 is provided separating from the indicator 111.
As mentioned hereinbefore, the portable telephone circuit 222 is actuated and the radio communication can be executed, when the lower part body of equipment 12 is inserted into the personal computer 2 in a state that the upper part body of equipment 11 is opened to the lower part body of equipment 12 in a predetermined angle. In this case, the consumption of the secondary cell 162 can be reduced, since the secondary cell 162 is charged by the electric power supplied from the personal computer 2.
Besides, the secondary cell 162 included in the communication device 1 can be charged by only inserting the lower part body of equipment 12 into the IC card slot 31, even if neither the conversation nor the data communication is executed.
Further, the communication device 1 of the embodiment 2 can be used as a portable telephone by the electric power of the secondary cell 16 included in the communication device 1, when it is not connected to such other terminal units as the personal computer 2.
<EMBODIMENT 3>
Then, the embodiment 3 of the present invention will be described. It is difficult to mount the projects of the dial button 121 on the communication device 1, when the communication device 1 is used as a portable telephone. For this reason, it is effective to load the sheet switch 121a on the communication device 1.
However, it sometimes happens that the sheet switch 121a will be operated wrongly by pressure, if the sheet switch 121a is inserted into the IC card slot 31 of the personal computer 2, when the sheet switch 121a is mounted on the JEIDA/PCMCIA connector 14 side.
The communication device 1-2 of the embodiment 3 is constructed to prevent the wrong operation of the sheet switch 121a. Fig. 9 is a diagram indicating a construction of principle parts of the embodiment 3 of the present invention. In Fig. 9, the communication device 1-2 of the embodiment 3 is provided with an AND
circuit which obtains a AND of the input information inputted from the sheet switch 121a and the register signal(hereinafter referred to as - REG signal "L" ) supplied from the personal computer 2 through the connector 14, when the communication device 1-2 is mounted on the personal computer 2 and supplies the portable telephone circuit 222 with the output.
Further, other constructions are the same as those of the embodiment 2, so the detailed description about them will be omitted.
According to the above-mentioned construction, - REG signal "L" which is supplied from the personal computer 2 to the card side is inputted into the AND
circuit 168, when the sheet switch 121a is inserted into the personal computer 2.
On the other hand, the input information "H" is inputted into the AND circuit 168, when one sheet of a plurality of sheets included in the sheet switch 121a is ~144i48 pushed by the wrong operation.
Then, the output of the AND circuit 168 is converted into "L" so that the portable telephone circuit 222 will not be actuated. Namely, the portable telephone circuit 222 will not be actuated, even if the sheet switch 121a is operated wrongly, so the wrong operation can be avoided.
Further, although the sheet switch 121a is mounted on the communication device 2-1 in the embodiment 3, the wrong operation can be avoided, even if , for instance, the dial switch is mounted.

The data bus DO-15 of 16 bits and the address bus AO-25 of 26 bits are connected to the LSI 170 from the personal computer 2 through the connector 14. REG
signal is inputted into the AND circuit 169.
Other constructions are the same as those of the embodiment 2, so the detailed description about them will be omitted.
According to the above-mentioned construction, the REG signal will be converted into "L", when the communication device 1-3 is mounted on the IC card slot 31 of the personal computer 2. The output of the AND
circuit 169 will be converted into "L", and the output will be inputted into the LSI 170.

Hy these operations, the nonvolatile memory 172 within the communication device 1-3 can be easily accessed by the personal computer 2.
Besides, the switch selective signal transmitted from the dial switch 121 is outputted to the portable telephone circuit 222 and the MPU 171, and MPU 171 monitors the input from the dial switch 121 all the time.
Hereupon, the MPU 171 executes the writing or the reading of the switch selective signal following the specific input for the nonvolatile memory 172, when a specific input was detected from the dial switch 121.
The writing of data into the nonvolatile memory 172 by the dial switching operation will be described in detail. Fig. 11 is a flowchart indicating a procedure for writing data into the nonvolatile memory by the dial switching operation of the embodiment 4 of the present invention. The writing of data will be described by referring to Fig. 11.
First of all, the MPU 171 compares the switch selective signal transmitted from the dial switch 121 with the predetermined initiation switch input procedure (Step S31). Hereupon, the process returns to the process of Step S31, when the switch selective signal is not the same procedure as the initiation switch input procedure.
On the other hand, the switch selective signal should be stored in the unillustrated register Rn installed on the MPU 171, when the switch selective signal is the same procedure as the initiation switch input procedure (Step S32).
Then, MPU 171 compares the switch selective signal with the predetermined termination switch input procedure (Step S33). Hereupon, the process returns to the process of Step 532, when the switch selective signal is not the same procedure as the termination switch input procedure.
On the other hand, the MPU 171 sets the gate signal *G which is transmitted to the bus buffer of the LSI 170 to "H" and separates the nonvolatile memory 172 from the personal computer 2, when the switch selective signal is the same procedure as the termination switch input procedure (Step S34).
Further, the MPU 171 reads out the switch selective signal from the unillustrated register Rn which exists inside, and writes it into the nonvolatile memory 172 (Step S35). The MPU 171 sets the gate signal *G which is transmitted to the bus buffer of the LSI 170 to "L", and connects the nonvolatile memory 172 to the personal computer 2 (Step S36).
By these operations, the data can be written into the nonvolatile memory 172 by the operation of the dial switch 121. Besides, the nonvolatile memory 172 can be accessed from the personal computer 2.
Accordingly, the telephone directory data can be exchanged between the communication device 1-3 and the personal computer 2, when the data is the telephone directory data. Besides, the exchange information can be limited by checking the password between the nonvolatile memory 172 in which the personal identification password is stored and the personal computer 2, when the data is a personal identification password.

'''"' - 2 1 4 4 1 4 8 Then, the secondary cell unit 16 which is one characteristic of the embodiment 2 will be described.
Fig. 8 is a diagram indicating a construction of the secondary cell unit 16. In Fig. 8, the secondary cell unit 16 is connected to the personal computer 2 through one part of terminals VCC, CD1, CD2 installed on the connector 14, and is connected to the antenna 13 through the portable telephone circuit 222.
The secondary cell unit 16 comprises a DC-DC
convertor 161 which is connected to the terminal VCC, a secondary cell 162, a comparator 163 consisting of the comparators 163a - 163c and an indicator -164 which is connected to the secondary cell 162 through each of the comparators and the resistances R2 - R4 corresponding to the comparator.

In the above-mentioned construction, as shown in Fig. 5, the personal computer 2 will connect the card diction terminals CD1 and CD2 on the JEIDA/PCMCIA
interface to the terminal GND, if the lower part body of equipment 12 is inserted into the IC card slot 31.

The electric power is supplied to the secondary cell 162 through the DC-DC convertor 161 so that the secondary cell 162 will be charged.
Then, the portable telephone circuit 222 is actuated by the electric power supplied from the secondary cell 162, and the radio data communication is executed.
Besides, the charging voltage which is charged into the secondary cell 162 is compared with the threshold voltage which was set up previously in each of comparators 163a - 163c. The corresponding light-emitting diodes 164a - 164c installed on the indicator 164 are lighted up, when the charging voltage exceeds the threshold voltage.

<EMBODIMENT 3>
Then, the embodiment 3 of the present invention will be described. It is difficult to mount the projects of the dial button 121 on the communication device 1, when the communication device 1 is used as a portable telephone. For this reason, it is effective to load the sheet switch 121a on the communication device 1.
However, it sometimes happens that the sheet switch 121a will be operated wrongly by pressure, if the sheet switch 121a is inserted into the IC card slot 31 of the personal computer 2, when the sheet switch 121a is mounted on the JEIDA/PCMCIA connector 14 side.
The communication device 1-2 of the embodiment 3 is constructed to prevent the wrong operation of the sheet switch 121a. Fig. 9 is a diagram indicating a construction of principle parts of the embodiment 3 of the present invention. In Fig. 9, the communication device 1-2 of the embodiment 3 is provided with an AND
circuit which obtains a AND of the input information inputted from the sheet switch 121a and the register signal(hereinafter referred to as - REG signal "L" ) supplied from the personal computer 2 through the connector 14, when the communication device 1-2 is mounted on the personal computer 2 and supplies the portable telephone circuit 222 with the output.
Further, other constructions are the same as those of the embodiment 2, so the detailed description about them will be omitted.
According to the above-mentioned construction, - REG signal "L" which is supplied from the personal computer 2 to the card side is inputted into the AND
circuit 168, when the sheet switch 121a is inserted into the personal computer 2.
On the other hand, the input information "H" is inputted into the AND circuit 168, when one sheet of a plurality of sheets included in the sheet switch 121a is ~144i48 pushed by the wrong operation.
Then, the output of the AND circuit 168 is converted into "L" so that the portable telephone circuit 222 will not be actuated. Namely, the portable telephone circuit 222 will not be actuated, even if the sheet switch 121a is operated wrongly, so the wrong operation can be avoided.
Further, although the sheet switch 121a is mounted on the communication device 2-1 in the embodiment 3, the wrong operation can be avoided, even if , for instance, the dial switch is mounted.

The data bus DO-15 of 16 bits and the address bus AO-25 of 26 bits are connected to the LSI 170 from the personal computer 2 through the connector 14. REG
signal is inputted into the AND circuit 169.
Other constructions are the same as those of the embodiment 2, so the detailed description about them will be omitted.
According to the above-mentioned construction, the REG signal will be converted into "L", when the communication device 1-3 is mounted on the IC card slot 31 of the personal computer 2. The output of the AND
circuit 169 will be converted into "L", and the output will be inputted into the LSI 170.

Hy these operations, the nonvolatile memory 172 within the communication device 1-3 can be easily accessed by the personal computer 2.
Besides, the switch selective signal transmitted from the dial switch 121 is outputted to the portable telephone circuit 222 and the MPU 171, and MPU 171 monitors the input from the dial switch 121 all the time.
Hereupon, the MPU 171 executes the writing or the reading of the switch selective signal following the specific input for the nonvolatile memory 172, when a specific input was detected from the dial switch 121.
The writing of data into the nonvolatile memory 172 by the dial switching operation will be described in detail. Fig. 11 is a flowchart indicating a procedure for writing data into the nonvolatile memory by the dial switching operation of the embodiment 4 of the present invention. The writing of data will be described by referring to Fig. 11.
First of all, the MPU 171 compares the switch selective signal transmitted from the dial switch 121 with the predetermined initiation switch input procedure (Step S31). Hereupon, the process returns to the process of Step S31, when the switch selective signal is not the same procedure as the initiation switch input procedure.
On the other hand, the switch selective signal should be stored in the unillustrated register Rn installed on the MPU 171, when the switch selective signal is the same procedure as the initiation switch input procedure (Step S32).
Then, MPU 171 compares the switch selective signal with the predetermined termination switch input procedure (Step S33). Hereupon, the process returns to the process of Step 532, when the switch selective signal is not the same procedure as the termination switch input procedure.
On the other hand, the MPU 171 sets the gate signal *G which is transmitted to the bus buffer of the LSI 170 to "H" and separates the nonvolatile memory 172 from the personal computer 2, when the switch selective signal is the same procedure as the termination switch input procedure (Step S34).
Further, the MPU 171 reads out the switch selective signal from the unillustrated register Rn which exists inside, and writes it into the nonvolatile memory 172 (Step S35). The MPU 171 sets the gate signal *G which is transmitted to the bus buffer of the LSI 170 to "L", and connects the nonvolatile memory 172 to the personal computer 2 (Step S36).
By these operations, the data can be written into the nonvolatile memory 172 by the operation of the dial switch 121. Besides, the nonvolatile memory 172 can be accessed from the personal computer 2.
Accordingly, the telephone directory data can be exchanged between the communication device 1-3 and the personal computer 2, when the data is the telephone directory data. Besides, the exchange information can be limited by checking the password between the nonvolatile memory 172 in which the personal identification password is stored and the personal computer 2, when the data is a personal identification password.
