Before explaining the disclosed embodiments of the present invention in detail it is to be understooα that the invention is not limited in its application to the details of the particular arrangements shown since the invention is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limita- t on.
DETAILED DESCRIPTION
Referring to Figures 1-4, the calculator shown there has a generally rectangular casing 20 with a flat top wall 21 having a laterally elongated window 22 for displaying numbers and a plurality of oval openings 23 at which the calculator keys K are located.
As shown in Figure 4, the top wall of the calculator casing has a thin, flat, rigid, metal panel 21a covered on 'the outside by gold or silver plating 21b for a visually attractive appearance.
Each key is an oval-cut, cabochon, semi-precious jewel stone with a shape as shown in Figures 5 and 6. The jewel stone has a convex dome 24 on the top projecting up from an elliptical side edge 25 (Fig. 4) and an oval flange 2b on the bottom projecting laterally outward from the side edge 25 along its complete extent. The bottom flange 26 pre¬ sents a flat top face 27 (Fig. 5; surrounding the side edge 25 and extending perpendicular to it. Tne bottom flange of each key has a flat bottom face 26 (Fig. 6) to which a thin, electrically conductive, metal foil 29 is adhesively bonded. This foil is the movable electrode of a capaci¬ tance switch of known design.
In Figure 1 all of the keys are the same size and orientation in the top wall of the calculator except a larger key K' , which is the "+" key that a user depresses to add numbers. Key K' is larger than the other keys ana it is elongated from front-to-back across the top of the calculator whereas the other keys K are elongated from side-to-side across the calculator. This larger key K' except for its size has the same snape as the otner Keys, with a domed top segment projecting up rrom an ova side edge ana an enlarged, f at-oottomed fianqe De ow tne side edge .
Referring to Figure 4, the top wall panel 21a of the calculator casing is on top of a support frame 30 of rigid dielectric plastic material. Frame 30 is formed with a plurality of oval top openings 31 each of which is slightly larger than the corresponding key at its oval side wall 25, and oval bottom openings 32, each of which is slightly larger than the respective key at its bottom flange 26. Each bottom opening 32 in the frame intersects a corre- sponding top opening 31 at a respective downwardly-facing shoulder 33, which is engageable by the top face 27 (Fig. 6 ) of the bottom flange on the corresponding key to provide an upper limit stop for the key. Each key can be pushed down into the casing by the pressure of a person's finger, and when this happens the bottom flange 26 of the key slides down the bottom opening 32 in the support frame 30 inside the calculator casing directly below its top wall 21.
A flexible and resilient diaphragm 34 of suitable rub- ber-like material directly overlies a generally flat print¬ ed circuit board B that carries the electronic components and wiring of the calculator. This printed circuit board may be of known design. Below each key it carries the fixed electrode 35 of a capacitance switch of known design. The diaphragm 34 has a plurality of upwardly projecting cylindrical nodes 36, one beneath each key K or K' . Each node has a flat top wall 37 that engages the metal foil 29 on the bottom of the corresponding key. A pad 38 of rela¬ tively soft, compressible and resilient material is adhe- εively affixed to the bottom face of the top wall of each node 36 in the diaphragm.
Normally, as shown in Figure 4, the nodes 36 of the diaphragm hold the corresponding keys up against tne down¬ wardly- facing shoulder 3ό in the frame 30 below the top wall of the casing. In this position of the parts, the soft pad 38 in each node is spaced above the corresponding fixed electrode 35 of the capacitance switch operated by that key .
When any key is depressed manually, the corresponding upstanding node 36 of diaphragm 34 is flattened and its paα 38 moves down against the fixed switch electrode 35. The downward movement of the foil layer 29 on the bottom of that key toward the fixed electrode 35 directly below it produces a switching action in a well-known manner. When finger pressure is removed from the key that has been depressed, the node 36 below that key springs back to the position shown in Figure 4.
As indicated by the shading' in Figure 1, all of the calculator keys except the "C, ON" key, the "OFF" key and the larger "+" key K' are substantially colorless, translu¬ cent crystal, the "C ON" key is jade, the "OFF" key is rose quartz or garnet, and the "+" key is amethyst. However, it is to be understood that all the keys may be of the same semi-precious jewel stone, such as amethyst, or tney may be a variety of different semi-precious or precious jewel stones of different colors, such as amethyst, rose quartz, blue agate, aventurine, carnelian, mother-of-pearl, garnet, pearl, ruby, emerald, sapphire and diamonα arranged in a predetermined multi-color pattern or arranged randomly.
Figure 7-12 shows a second embodiment of the invention which is essentially the same as the first embodiment (Figs. 1-6) except that the keys are emerald-cut semi¬ precious jewel stones instead of the oval cabochons of the first embodiment. The elements of this second embodiment are given the same reference numerals with a "-2" suffix added as the corresponding elements of the first embodiment so the detailed description need not be repeated.
As shown in Fig. 11 and 12, each key in the second embodiment of the invention has a thin, flat, bottom flange 26-2 projecting out laterally from a side wall 25-2 of tne jewel stone that is rectangular in outline except for beveled corners 25a-2. Each key has a bevel-eoged too segment 24-2 that normally projects aoove tne top wall i-_ of the calculator casing. The side wal_. 25-2 of tne key fits snugly but εlidably in the corresponding opening 23-2 in the top wall 21-2 of the casing. The top face 27-2 of the bottom flange 26-2 of each key normally engages a corresponding downwardly-facing shoulder 33-2 provided by the frame 30-2 inside the calculator casing beneath its top wall 21-2. The bottom flange 26-2 of each key is snugly but slidably received in a corresponding bottom opening 32- 2 in frame 30-2.
With this arrangement, any key can be pushed down by a person's finger to perform a switching function in the manner already described for the first embodiment of thee invention (Figs. 1-6).
As indicated by the shading in Figure 7, the calcula¬ tor shown there has a multi-colored keypad including a rose quartz or garnet "C ON" key, a jade "5" key, an aventurine "%" key, a blue agate "OFF" key, a carnelian "+" key, and substantially colorless, translucent jewel stones for all the other keys. However, it is to be understood that any desired pattern of differently colored jewel stones may be provided in the key.pad, such as by having amethyst as all of the number keys.
Figure 13 shows another embodiment of the invention which is .like the embodiment of Figure 7 except that it has a larger window 22-3 for displaying the numbers. Figure 14 shows a fourth embodiment which is like
Figure 13 except that it has keys of differently-colored semi-precious jewel stones, with all the keys in a given diagonal row the same type of. jewel stone. For example, starting at the upper left corner, the "C ON" key 40 is rose quartz or garnet, the diagonally aligned "7" key 41 and "5" key 42 are blue agates, the diagonally aligned "8" key 43, "4'' key 44 and "%" key 45 are carnelians. the diagonally aligned "9" key 46, "5" key 47, "1" key 48 and "OFF" key 49 are amethysts, the diagonally aligned "X" Key 50, "6" key 51, "2" key 52 and "0" key 53 are aventurines, the diagonally aligned "-" key 54, "-" key 55, "3" key 56 andd decimal point key "57" are garnets or rose quartzes, the diagonally aligned "M " key 58 and "=" key 59 are blue agates, the larger "+" key 60 is an amethyst, the "M-" key 61 is a blue agate, and the "M+" key 62 in the lower right corner is a carnelian.
