Then, when the cable 19 is connected to the connector 13 at the lower connection position B, the desk microphone unit 1 is in a table-buried state.

The above rear view of FIG. 2 shows a state where the connector 13 is at the rear connection position A. Connector 13 faces rearward. The bottom view of FIG. 3 shows a state where the connector 13 is at the lower connection position B. The connector 13 faces downward. When the connector 13 is at the lower connection position B, the cap 23 is attached to the connector recess 15 of the base 3 as shown in the side view of FIG. 4 and the plan view of FIG. As a result, the inside of the connector recess 15 is hidden.

FIG. 6 is a front view of the desktop microphone unit 1. FIG. 6 shows a speaker 25 at the upper front of the base section 3.

FIG. 7 is an exploded perspective view of a configuration related to the connector 13. Each of the two connectors 13 is attached to a connector case 31 with a nut 33. The connector case 31 is sandwiched between two bearings 35. Each bearing bracket 35 is attached to the lower case 9 with a screw 37. The connector case 31 is attached to the bearing bracket 35 with a stepped screw 39. The two stepped screws 39 function as shafts, and the connector case 31 rotates together with the connector 13. The connector case 31 fits into an opening 41 provided at the bottom of the connector recess 15 of the lower case 3. This positions the connector 13 in the connector recess 15. ing.

[0027] At both ends of the connector case 31, a toggle locking mechanism 43 is provided. The lock mechanism 43 includes a lock plate 45 and a leaf spring 47. The lock plate 45 is integrated with the connector case 31. Further, the leaf spring 47 is held by the lower case 9 so as to be able to bend.

FIG. 8 shows the lock mechanism 43. Lock recess 51 at 3 places on the edge of the lock plate 45,

53 and 55 are provided. On the other hand, the plate spring 47 is provided with a lock projection 57. The lock mechanism 43 is held at a position where the lock projection 57 of the leaf spring 47 is fitted into the lock recesses 51, 53, 55 of the lock plate 45.

As described above, in the lock mechanism 43, three lock positions are set by the three lock recesses 51, 53, and 55. The lock recess 51 corresponds to the rear connection position A of the connector 13. The locking recess 55 corresponds to the lower connection position B of the connector 13. The lock recess 53 is located between the lock recess 51 and the lock recess 55. The locking recess 53 corresponds to an intermediate position M between the rear connection position A and the lower connection position B as described below.

FIGS. 9 to 11 show the relationship between the lock mechanism 43 and the connector direction. As shown in FIG. 9, when the lock concave portion 57 of the leaf spring 47 is engaged with the lock concave portion 51 of the lock mechanism 43, the connector 13 is held at the rear connection position A. As shown in FIG. 10, the connector 13 is held at the intermediate position M when the lock projection 53 is engaged with the lock projection 53. Further, as shown in FIG. 11, when the lock concave portion 57 is engaged with the lock concave portion 55, the connector 13 is held at the lower connection position B.

Here, as shown in FIGS. 9 and 11, in the present embodiment, connector recess 15 is relatively small. Therefore, when the connector 13 is located at the rear connection position A and the lower connection position B, the connector 13 interferes with the wall surface of the concave portion 15 for the finger force connector of the human having the mating connector 17. Therefore, the installation work of the cable 19 is not easy.

On the other hand, as shown in FIG. 10, when the connector 13 is at the intermediate position M, the gap between the force of the mating connector 17 and the wall surface of the connector recess 15 increases. And the insertion of the human finger is easy, and the work of attaching and detaching the cable 19 is also easy.

FIG. 12 is a perspective view of the desktop microphone unit 1 as viewed from below. Fig. 12 shows the stopper 61 It is shown. The stopper 61 is a projection provided on the surface of the connector case 31. The stopper 61 is provided between the two connectors 13.

FIGS. 13 and 14 are cross-sectional views passing through the stopper 13. FIG. In FIG. 13, the connector 13 is at the rear connection position A. In FIG. 14, the connector 13 is at the lower connection position B. FIG. 13 and FIG. 14 show the positions of the rear end 63 and the front end 65 of the stopper 61.

As shown in FIG. 13, the position of the rear end 63 of the stopper 61 is such that when the connector 13 is at the rear connection position A, the rear end 63 is It is set so that it hits. As a result, when the connector 13 rotates backward, the rear end 63 abuts against the wall surface 67 of the connector recess 15 before the mating connector 17.

As shown in FIG. 14, the position of the front end 65 of the stopper 61 is such that when the connector 13 is at the lower connection position B, the front end 65 is on the front wall surface 69 of the connector recess 15. It is set to hit. Thus, when the connector 13 rotates backward, the front end 53 abuts against the front wall surface 69 of the connector recess 15 before the mating connector 17.

The configuration of the desktop microphone unit 1 according to the present embodiment has been described above. Next, the operation of the desktop microphone unit 1 during the cable attaching operation will be described.

First, a description will be given of a cable attaching operation when the desk microphone unit 1 is used in a state where the desk is put out from the back. In this case, the connector 13 is rotated to be located at the intermediate position M. Then, the cable 19 is connected to the connector 13. At this time, the mating connector 17 is held by the finger and inserted into the connector recess 15. Then, with the ring on the outer periphery of the mating connector 17 being slid, the mating connector 17 and the connector 13 are fitted and the ring is separated therefrom. As a result, both connectors 13 and 17 are locked.

[0039] Then, the connector 13 is also rotated to the rear connection position A by the intermediate position M force. At this time, the lock mechanism 43 shifts from the state of FIG. 10 to the state of FIG. The leaf spring 47 is bent, and the lock projection 57 of the leaf spring 47 comes off the lock recess 53 of the lock plate 45. Then, the lock plate 45 rotates, and the lock convex portion 57 fits into the next lock concave portion 51. As a result, the connector 13 is held at the rear connection position A.

The above is the cable attaching operation when using the desktop microphone unit 1 with the rear surface exposed. As described above, in the present embodiment, since the connector 13 can be rotated, the operation is simple. The In addition, when the cable is attached, the connector 13 is disposed at the intermediate position M, so that the surrounding gap is increased, which also facilitates the work.

In the above operation, even if the connector 13 is strongly turned backward, the mating connector 1

The stopper 61 comes into contact with the rear wall surface of the connector recess 15 before 7. Therefore, it is possible to prevent an excessive force from being applied to the cable 19.

Next, a description will be given of a cable attaching operation when using the tabletop microphone unit 1 in a table-top state. In this case, the cable 19 is previously passed through a hole in a table or the like and drawn out to the upper surface of the table or the like. Then, the cable 19 is connected to the connector 13 at the intermediate position M in the same manner as in the above-described work of rearing.

Then, the connector 13 is turned from the intermediate position M to the lower connection position B. At this time, the hook mechanism 43 shifts from the state of FIG. 10 to the state of FIG. Leaf spring 47 is radius, leaf spring

Moves from the lock concave portion 53 of the lock plate 45 to the lock concave portion 55. As a result, the connector 13 is held at the lower connection position B.

The above is the cable mounting operation when using the tabletop microphone unit 1 in a table-topped state.

Even in this operation, the connector 13 can be rotated, so that the operation is simple. In addition, the clearance around the connector when attaching the cable is large, so the work is easy. Also in this operation, the function of the stopper 61 can prevent the cable 19 from being subjected to excessive force.

Next, an operation of removing the cable 19 in the state of being exposed from the back will be described. In this case, first, the connector 13 is rotated from the rear connection position A to the intermediate position M. The lock mechanism 43 shifts from the state of FIG. 9 to the state of FIG. The leaf spring 47 is deflected, and the lock projection 57 of the leaf spring 47 moves from the lock recess 51 to the lock recess 53. As a result, the connector 13 is held at the intermediate position M.

Then, the mating connector 17 is detached from the connector 13. At this time, the mating connector 17 is held by a finger, and the outer ring is slid. As a result, the lock between the connectors is released. Then, the mating connector 17 is separated from the connector 13.

[0047] The above is the operation of removing the cable 19 in the state of being exposed from the back. Even in this operation, the connector 13 can be rotated, so that the operation is simple. Also, when removing the cable, the clearance around the connector at the intermediate position M is large, so the work is easy. Next, an operation of removing the cable 19 in a table-buried state will be described. In this case, first, the connector 13 is turned from the lower connection position B to the intermediate position M. The lock mechanism 43 shifts from the state of FIG. 11 to the state of FIG. The leaf spring 47 is bent, and the lock projection 57 of the leaf spring 47 moves from the lock recess 55 to the lock recess 53. As a result, the connector 13 is held at the intermediate position M. Then, the mating connector 17 is detached from the connector 13 in the same manner as the operation in the state where the rear surface is exposed.

[0049] The above is the operation of removing the cable 19 in the buried state. Even in this operation, the connector 13 can be rotated, so that the operation is simple. Also, when removing the cable, the clearance around the connector at the intermediate position M is large, so the work is easy.

Next, a description will be given of the work of switching from the rear-facing state to the table-top state. In this case, the above-described cable removal work on the rear side is performed, and subsequently, the cable mounting work on the table is performed. In addition, in the work of switching the table-top state force to the back-out state, the above-mentioned table-out cable removal work is performed, and subsequently, the back-out cable attachment work is performed.

[0051] In these switching operations, since the connector 13 is rotated, the operation is simple. Also, when removing and attaching cables, the clearance around the connector at the intermediate position M is large, so work is easy.

[0052] The tabletop electronic device according to the embodiment of the present invention has been described above. According to the present embodiment, connector 13 is rotatably supported. When the connector 13 is rotated to the rear connection position A, the tabletop electronic device is brought out of the rear. Further, when the connector 13 is moved to the lower connection position B, the tabletop electronic device enters the tabletop state. Therefore, it is easy to switch between the back-out state and the table-filled state.

Further, as described above, since the connector 13 has a rotating structure, the connector can be easily attached and detached in a small space.

Further, a connector 13 is provided in a connector recess 15 provided in a lower portion on the rear side of the main body. Thereby, the exposure of the connector portion is reduced. This is advantageous in terms of appearance.

In addition, the desktop electronic device of the present embodiment has the connector 13 It has an intermediate position holding portion that holds the intermediate position M between the connection position A and the lower connection position B. This allows the mating connector 17 to be easily attached to and detached from the connector 13 while the connector 13 is held at the intermediate position M. Further, as described above, when the connector 13 is at one or both of the rear connection position A and the lower connection position B, the mating connector 17 and the wall surface of the connector recess 15 may be close to each other. Therefore, the connector recess 15 can be made smaller, and the space for the connector portion can be made smaller. As a result, the entire device body can be made compact, and the device can be downsized.

In addition, the desktop electronic device of the present embodiment includes a stopper portion, and the stopper portion adjusts the rotation range of the connector 13 so that the mating connector 17 connected to the connector 13 does not contact the wall surface of the connector recess 15. Restrict to a range. Thus, the load on the mating connector 17 and the cable 19 can be reduced.

In the present embodiment, the desktop electronic device is a desktop microphone unit. However, within the scope of the present invention, the tabletop electronic device may be a device other than the tabletop microphone unit.
