BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a view showing a key top body 1 with a film plate (hereinafter, simply referred to as a “key top body”) 1 according to an embodiment of the present invention. FIG. 1A is a perspective view, and FIG. It is AA sectional drawing of FIG.1 (a). As shown in FIG. 1, the key top body 1 includes four key tops (hereinafter, referred to as "outer peripheral key tops") 10-2, 3, around a central key top (hereinafter, referred to as "central key top") 10-1. The key tops 10-1, 2, 3, 4, 5 are integrated by a connecting portion (hereinafter, referred to as “outer connecting portion”) 25 or a connecting portion (hereinafter, referred to as “central connecting portion”) 27. It is configured to be connected to. Hereinafter, each component will be described in detail. When both the center key top 10-1 and the outer peripheral key tops 10-2 to 10-5 are indicated at the same time, it is referred to as "key top". Department ".
[0013]
In this embodiment, the shape of each key top 10-1, 2, 3, 4, 5 is the same. That is, each of the key tops 10-1 to 10-5 has the same shape as the upper shape of each of the key tops 10-1 to 10-5 by bending the plate-shaped film plate 20 upward and bending, and the concave portion on the lower surface side of the curved portion. The key top main body 30 is formed inside. That is, each of the key tops 10-1 to 10-5 in this embodiment has a structure in which the upper surface of the key top main body 30 is covered by the film plate 20 which is curved and deformed upward. A pressing portion 35 for pressing a switch contact (not shown) protrudes from the lower surface of the key top main body 30.
[0014]
On the other hand, the film plate 20 protrudes from the outer periphery of each of the key tops 10-1 to 10-5, and the film plate 20 located on the outer periphery constitutes the collar portion 23. The adjacent outer peripheral key tops 10-2, 3, 4, and 5 are connected in a ring shape (including a polygonal shape, the same applies hereinafter) by a total of four outer circumferential connecting portions 25 protruding from the outer circumference of the flange portion 23. I have. The central key top 10-1 branches off from the middle (center) of each of the four outer peripheral connecting portions 25 connected in a ring shape and goes toward the center, and is connected and connected to the flange portion 23 of the central key top 10-1. They are connected by four central connecting portions 27. A positioning hole 29 for positioning the keytop body 1 to another member is provided at each of the branch portions (four places) of the outer peripheral connecting portion 25 and the central connecting portion 27.
[0015]
The reason why the collar portion 23 is provided is as follows. That is, the inside of the case can be seen from the gap between the opening of the case and the side surface of the key tops 10-1 to 10-5 when the key tops 10-1 to 10-5 are exposed from the opening of the case (not shown) covering the key top body 1. This is intended to prevent the key tops 10-1 to 5-5 from being exposed upward beyond a predetermined dimension from the opening of the case. If the gap is small, the flange 23 may not be provided.
[0016]
In the key top body 1 configured as described above, a case (not shown) is installed on the upper surface side, and the upper portions of the key tops 10-1 to 10-5 are exposed from the openings provided in the case. A switch contact (not shown) is installed below the pressing portions 35 of -1 to 5 and the switch contacts are pressed by pressing the upper surfaces exposed from the openings of the cases of the respective key tops 10-1 to 10-5, thereby pressing the switch contacts. Turn on. On the other hand, each positioning hole 29 provided in the key top body 1 is positioned by being inserted and engaged with a not-shown locking projection projecting from a case or a member on the switch board side provided with a switch contact.

In the key top body 1 according to the above-described embodiment, the key tops 10-1 to 10-5 are connected by the connecting portions 25 and 27. Is lowered, the amount of other surrounding key tops 10-1 to 10-5 falling in conjunction therewith is small. The reason is that the key tops 10-1 to 5 are connected by only the connecting parts 25 and 27 by providing the opening 37 formed by cutting the film plate 20 between the key tops 10-1 to 10-5. This is because each of the key tops 10-1 to 10-5 can independently operate smoothly. As described above, the key tops 10-1 to 10-5 operate substantially independently, so that even if the key top plate 1 is downsized and the separation distance between the key tops 10-1 to 5 becomes short, the key tops 10-1 to 10-5 become small. There is no hindrance to the independent pressing operations of -1 to -5. In particular, in the case of this embodiment, the four outer peripheral key tops 10-2 to 10-5 are connected in a ring shape by the outer peripheral connecting portion 25, so that when handling the key top body 1, each key top 10-1 to 5-5 is used. It does not move apart and is easy to handle.
[0018]

As shown in FIG. 1 of Patent Document 1, the positioning hole 29 does not need to be provided further on the outer peripheral side of the entire portion of the key top plate on which a plurality of key tops are provided, thereby reducing the outer dimensions of the key top body 1. I can do it. Further, since these positioning holes 29 are provided at the respective branch portions of the outer peripheral connecting portion 25 and the central connecting portion 27, the positioning holes 29 are positioned with respect to all of the connecting portions 25 and 27 extending outward from the key tops 10-1 to 10-5. Since the holes 29 are provided and positioning can be achieved, play can be prevented by the positioning of the key tops 10-1 to 10-5, and independent operations can be performed more reliably.
[0019]
In order to manufacture the key-top body 1, first, a film plate 20 made of a flat synthetic resin film having no holes and having flexibility (for example, a polyethylene terephthalate film which is a thermoplastic film) is prepared. Next, as shown in FIG. 2A, the film plate 20 is preformed by pressing to form a curved portion in the film plate 20 which is upwardly curved in the same shape as the upper shape of each of the key tops 10-1 to 10-5. To form
