Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a flat press switch device in which a plurality of switches are arranged on a plane.

Conventionally, this type of switch device has either individually manufactured push-button switches arranged on a flat operation panel, or a frame part that supports the operation buttons of the push-button switches integrated with a plurality of push-button switches. Structures such as those formed in this manner are generally used. In general, conventional switch devices have the disadvantage that it is difficult to arrange the operation buttons of each push button switch uniformly on a flat surface, which tends to spoil the aesthetic appearance. Since the structure is arranged in an array, the structure inevitably becomes complicated due to the support mechanism of the operation buttons, which results in poor assembly workability and a high unit price of the product. In addition, especially for devices where the stroke of the switch operation is small, it is desirable to display confirmation of the operation status.

Therefore, the present invention provides a flat type press switch device in which each operation part of a plurality of switches is formed from a flexible flat panel, and the entire device is formed into a sheet structure, thereby solving the above-mentioned conventional problems. This is an attempt to solve the problem.

Hereinafter, the present invention will be described in detail with reference to the drawings showing one embodiment.

The switch device 10 assembled by caulking the boss 16 as described above is fixed by screwing the screw holes 53A and 53B of the reinforcing plate 5 to a sub-panel or the like of a tape recorder (not shown). Furthermore, the display windows 12A, 12B, and 12C provided on the front panel 1 are irradiated with display light from the light emitting element 60. here,
The display chips 15A, 15B, and 15C provided in the display windows 12A, 12B, and 12C are made of synthetic resin mixed with a light-diffusing substance, so that a display with uniform brightness can be provided. Moreover, since the display chips 15A, 15B, 15C are simultaneously molded together with the ribs 13A, 13B, 13C, 13D and the boss 16 by intaglio molding, they can be placed at predetermined positions without requiring any special work process. Can be set.

In the embodiment configured as described above, each rib 13A, 13B, 13C,
Each operation section 11A, 11 divided by 13D
B, 11C, 11D, 11E, 11F, 11G
is deformable using the ribs 13A, 13B, 13C, and 13D as fulcrums, and is curved and deformed by an external force from the front side, thereby connecting the first contact portion 22 to the second via the operating protrusion 14. The first contact portions 22 act so as to come into contact with the contact portions 42, and each first contact portion 22 can be operated independently and reliably. In addition, since the ribs 13A, 13B, 13C, and 13D are independently distributed, the operation portion 11 can be easily deformed at the discontinuous portions, and the first The contact portion 22 can be operated. Compared to the case where the entire circumference of the operation part 11 is continuously surrounded by ribs, in this embodiment, it is about 1/
Operation was possible with a pressing force of about 3. Also,
Each of the above ribs 13A, 13B, 13C, 13D is
Since the back surface 1B of the front panel 1 is intaglio-molded, each operation section 11A, 11B, 11C, 11
Even if D, 11E, 11F, and 11G are arranged adjacent to each other, they will surely act as fulcrums. Furthermore, the rib 13
Since each insulating sheet body 2, 3, 4 and reinforcing plate 5 are positioned and fixed by each boss 16 integrally molded on A, 13B, 13C, and 13D, not only is the workability of assembling the device 10 good, but also the above-mentioned reinforcement Board 5
Accordingly, it is possible to prevent the respective sheet bodies 2, 3, 4 and the front panel 1 from bending and ensure flatness. Moreover, since each operating section 11 is formed on the front panel 1 whose flatness is ensured in this way, the switch device 10 has an excellent aesthetic appearance.
can be realized.

In addition, in the above-mentioned embodiment, the display chip 15
Although the ribs 13 are integrally molded with the ribs 13, they can also be provided independently by simultaneous molding of synthetic resin. Further, in this embodiment, only the reinforcing plate 5 is formed of a rigid plate material, and the other front panel 1 and each of the sheet bodies 2, 3, and 4 are formed of a flexible material. It is sufficient that the front panel 1 and the first contact insulating sheet body 2 disposed on the front panel 1 side are formed of a flexible material. Further, the first and second contact insulating sheet bodies 2 and 4 may be a single polyester sheet folded in two. Furthermore, in the flat type push switch device 10 as in this embodiment, the contact portions 22 and 42 are brought into contact by the pressing operation of each operation portion 11, and the switch is opened and closed with a small stroke. The operation status is displayed in each display window 12A, 12B,
Displaying by irradiating 12C with light is extremely effective in practice. Moreover, in this embodiment, the display windows 12A, 12B, 12C are provided with display chips 15A, 15B, 15C made of a synthetic resin material mixed with a light-diffusing substance, so that a uniform display can be obtained. The state is obtained.

In addition, in the above-mentioned embodiment, each rib 13A, 13B, 13C, made of synthetic resin mixed with a light-diffusing substance,
13D etc. by intaglio molding on the back side 1B of the front panel 1.
However, other molding methods such as injection molding of a synthetic resin material can also be used.

As is clear from the description of the embodiments described above, according to the present invention, a pair of insulating substrates each having a pair of contact portions printed thereon, and a plurality of openings corresponding to each of the contact portions are provided. and an insulating spacer member, wherein each of the pair of contact portions is arranged to face each other through the opening, and at least one of the insulating substrates is formed of a flexible thin film. In the device, displays for a plurality of operation parts corresponding to each opening of the insulating spacer member are provided on the back surface of a flexible flat panel, display windows for each operation part of the flat panel are provided, and a light-diffusing material is provided. A plurality of ribs are formed on the back surface of the flat panel along with a display chip that closes the display window using a synthetic resin mixed with a synthetic resin, and a plurality of ribs are formed along the division line of the operation section, and the flat panel and the flexible thin film are connected to the plurality of ribs. are arranged in parallel with each other through ribs, and the plurality of ribs are formed of a synthetic resin mixed with a light-diffusing substance together with the display chip. Each operating section can be flexed independently and reliably to perform switch operations with fewer malfunctions, and the operating status of each operating section can be displayed through a display window formed on the flat panel. Can be done. Moreover, in the flat type press switch device according to the present invention, since the display chip formed of synthetic resin mixed with a light-diffusing substance is provided as the rib in the display window, the operation state of the operation section can be displayed on the plane. When displaying light from the back side of the panel through the display window, a display state of uniform brightness can be obtained, and the display chip and each rib can be molded simultaneously using the same synthetic resin. This makes it possible to simplify the manufacturing process and provide products at low prices.
