FIG. 7 is an exploded perspective view for explaining the second embodiment, and FIG. 8 is a cross-sectional view of essential parts in FIG.

First, a first embodiment of the present invention will be described with reference to FIGS. 1 to 5, 11 is 2 mm thick
Key plate, 12 is the key top part of key plate 11
It is a key top case attached to 11a. The key top case 12 is attached to the first insulative case 12a having a recess 12c for holding the key top 11a and the first case 12a. The second case covers the key top 11a together with the first case 12a. And an insulating case 12b. 1
3 is a double-sided tape attached to the bottom of the first case 12a. In the present embodiment, the depth of the recess 12c is the thickness
It is formed so that it can hold a 2.3 mm key plate.

14 is the thickness as a spacer laminated on the double-sided tape 13.
It is a 0.3 mm double-sided tape. When the key plate having a thickness of 2.3 mm is mounted, the double-sided tape 14 is unnecessary as shown in FIG.

Reference numeral 15 is an LED light emitting element provided in the second case 12b.

Next, the inside of the second case 12b will be described with reference to FIG. The recess 12d is also formed in 12b. 15a and 15b are
The terminals of the light emitting element 15 and 16 are lithium batteries arranged in the recess 12d. The terminal 15a is bent so that it is always in contact with one electrode of the lithium battery 16. Reference numeral 17 denotes a base portion (the other end portion) attached to the bottom portion of the recess 12d of the second case 12b, and the front end portion (one end portion) is disposed in the other electrode of the lithium battery 16 with a gap. Light emitting element on the edge side

As is apparent from FIG. 4, one electrode of the lithium battery 16 is in contact with the key plate 11, and the two are electrically connected.

Next, the operation of this embodiment will be described with reference to FIG. When the switch 18 is pressed when locking / unlocking in a dark place such as at night, the elastic terminal 17 is pressed by the lithium battery 16 and a current flows through the light emitting element 15, so that the light emitting element 15 emits light. This light emission illuminates the keyhole and locks it.
Easy unlocking. When the force pushing the switch 18 is released, the elastic terminal 17 returns to its original position, the current flowing through the light emitting element 15 is cut off, and the light emitting element 15 stops emitting light.

According to the above configuration, by using the double-sided tape 14 used as the spacer, it can be attached to the key plate having a thickness of 2 mm,
Without using the double-sided tape 14, it can be attached to a 2.3 mm thick key plate.

Further, the static electricity accumulated in the human body flows to the key plate 11 through the conductive switch 18, and one terminal of the light emitting element is connected to one electrode of the battery, so that the electrostatic shock is alleviated. be able to.

Further, the terminal 15a of the light emitting element 15 is bent so as to always come into contact with one electrode of the lithium battery 16, and the terminal and soldering for connecting to this terminal are not required as in the conventional example, and the parts are The number of points can be reduced and the number of assembling steps can be reduced.

Next, a second embodiment will be described with reference to FIGS. 7 and 8. The same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In these figures, the parts different from the first embodiment are
Double-sided tape used as a spacer in the first embodiment
When 14 is removed and the key plate having a thickness of 2 mm is mounted, the conductive resin plate 21 is arranged between the key plate 11 and the lithium battery 16. The plate 21 made of a conductive resin is used to electrically connect one electrode of the lithium battery 16 and the key plate 11.

Even with such a configuration, the same effect as that of the first embodiment can be obtained.

(Effect of the Invention) As described above, according to the present invention, since the spacer can be arranged in the concave portion of the first case for holding the key top of the key plate, the spacer can be mounted on the key plates of various thicknesses. Is possible. Also, since the key plate is electrically connected to one electrode of the battery and the switch for pressing the elastic terminal to the other electrode of the battery is made of a conductive material, static electricity accumulated in the human body Can flow from your finger to the key plate through a conductive switch to relieve electrostatic shock. Further, since one terminal of the light emitting element is in contact with one electrode of the battery, the number of parts can be reduced and the number of assembling steps can be reduced.

Therefore, it is possible to realize a key top case with illumination, which can be attached to key plates of various thicknesses, which can alleviate electrostatic shock, reduce the number of parts, and reduce the number of assembling steps.
