Abstract

(57) [Summary] [Structure] The cap 1, which is fitted into the base 2 that fits into the plunger in the switch mechanism and is held by the locking parts 3 and 4, is made of an inexpensive opaque resin material. is clearly stated. [Effects] The conventional paper strip with written characters is no longer necessary, and the material of the cap 1 is made inexpensive, so that the price can be lowered.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is based on the keys on keyboards, which are widely used as information processing input devices. Regarding switches, especially regarding key tops that fit into the top surface of key switches. .

0002

[Conventional technology]

FIG. 5 is an exploded perspective view of a key top showing a conventional example. Traditionally, this type of key The top is made of opaque resin that is attached to the switch mechanism, as shown in Figure 5, for example. It has a base 2 molded with and a locking part 3b that fits the locking part 3a of this base 2. The cap 1e is molded from transparent resin and is fitted into the base. It is inserted between the cap 1e and the base 2, is glued to the base 2 surface, and is It had a piece of paper 6 on which the symbol was printed or displayed using a two-color shaping method.

0003 A keyboard switch with such a key top installed can switch all parts of the keyboard. They were arranged horizontally and vertically on the surface. In addition, the operator recognizes the characters written on the piece of paper 6. and press the necessary keyboard switches to input the input information to the information processing device. was.

[Problem that the idea aims to solve]

The conventional key tops mentioned above use characters as a means of displaying characters on the key tops. This requires a piece of paper on which is printed, and it also requires the work of pasting this piece of paper onto the base. The material of this cap must also be a transparent material. This means that the piece of paper The cost of materials and labor for pasting are added to the price of the key top, and the cap material is transparent. Since it is made of bright resin, the material cost is higher. For this reason, as a key top, It has the disadvantage of being expensive.

[0005] The purpose of this invention is to provide a cheaper key top to eliminate such drawbacks. That is.

[0006]

[Means to solve the problem]

The key top of this invention consists of a base that fits into the plunger of the switch mechanism, and a base that fits into the plunger of the switch mechanism. The camera is an opaque resin body that is fitted into the base of the camera and has letters written on one side. It is equipped with

【Example】

Next, the present invention will be explained with reference to the drawings.

[0008] Fig. 1 is an exploded perspective view of a key top showing an embodiment of the present invention, and Fig. 2 is an exploded perspective view of the key top of Fig. 1. FIG. This key top is As shown in Figures 1 and 2, the character 5 is written on the surface and the side of the recess on the bottom. A plate-shaped cap 1 in which a locking portion 3 protruding from the surface is formed, and a bottom of this cap 1. A convex portion is formed to be inserted into the recess of the surface, and the locking portion 3 is fitted into the side surface of the convex portion. It consists of a base 2 having a locking part 4 which is a recess.

[0009] The cap 1 may be made of inexpensive opaque resin, such as vinyl chloride or ABS. It is made of resin, and letters are displayed on its surface using a two-color molding method. To this This reduces the material cost of key tops and reduces the amount of paper that should be displayed and the work of pasting the paper. becomes unnecessary. Furthermore, base 2 can be manufactured in common for all key tops. You can get cheaper keycaps.

0010 Figures 3 (a) to (d) show various key top examples to which the key top structure of Figure 1 is applied. FIG. If you use the structure of the key top described above, as shown in the same figure, , the base 2 is manufactured in one type of shape, and only the caps are made from 1a to 1. By changing the shape as shown in d, various types of key tops can be manufactured at low cost. Also, when assembling the keyboard, attach base 2 to the keyboard surface in advance, and After that, fit the caps 1a to 1d onto each of the bases arranged on the keyboard. All you have to do is get it. This not only makes it easier to replace the cap, but also makes it easier to assemble the keyboard. It also has the advantage of making standing work easier.

[0011] Here, an example of specifying the chord name on the cap will be explained. Figures 4(a)-( c) is a partial sectional view of a cap showing an example in which a code name is clearly written on the cap. figure The cap 1 shown in 4(a) is an example in which the letters 5 are formed by a two-color molding method. Figure 4(b) ) is an example in which character 5 is formed by printing. In addition, FIG. 4(c) shows the cap 1. The surface is carved and the grooves are filled with colored paint.

0012

[Effect of the idea]

As explained above, the present invention involves attaching a piece of paper with the code name of the key to the base. Instead, the cap that fits into the base is made of an opaque and inexpensive resin material. By clearly marking the code name on the cap surface, material costs are lower and assembly is easier. This has the effect of providing inexpensive key tops.
