Abstract

PURPOSE:To obtain a panel switch to assemble easily and with a compact size by combining a plurality of push buttons integrally positioning them in a scope to prevent a linking operation side by side. CONSTITUTION:A push button 1 is linked to a neighboring push button through a slender linking belt 1a. The push button is normally made of a resin, and the linking belt 1a can be made by utilizing a sprue runner in the formation process as it is. The push buttons 1 are inserted in apertures 4a lined up on a panel 4. When the button 1 is pushed, a tact switch 2 is pressed, and when the button 1 is released, the tact switch 2 is restored to the initial position by the reaction of a spring. In this case, even though the linking belt 1a is extended further and heat-fused, the push button 1 and the panel 4 can get the same effect as far as the neighboring buttons are not linked by the stiffness of the linking belt 1a. As a result, the push buttons are not scattered in the assembling and disassembling works, and the maintenance can be carried out easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a panel switch mechanism used in office automation equipment.

[Conventional technology]

FIG. 5 is a plan view of a conventionally used general panel switch mechanism, 6pXJ is a right side sectional view of FIG. 5, and FIG. 7 is a right side sectional view during operation. Also the 8th
The figure is a plan view of a panel switch @ accommodation similar to this crosspiece. In the figure, 1 is a push button, and like the panel 4, most of it is a resin molding path. This push button 1 is on panel 4
is fixed by the heat-melting layer part 6, and then the characters 5 and the like are printed by screen printing or the like. 2 is a tact switch arranged on the board 3. The substrate 3 and the panel 4 are either not shown or are fixed to each other so as to maintain their positions.

Please briefly explain the operation. The push button l pressed with the finger 7 bends due to the elasticity of the arm IC, and when the tact switch 2 is pressed, the switch is turned on. When the finger 7 is released, the push button l returns to its original state. Tru. Note that Figure 8 shows a structure that is often used when the space between switches is narrow.
This eliminates the sideways protrusion of the arm.

[Problem that the invention is trying to solve]

Since the conventional panel switch mechanism is configured as described above, space is limited, and due to the miniaturization of tact switches and the increase in the number of switches on the panel operation surface and the miniaturization of equipment due to the multifunctionality of OAM devices. This method has the disadvantage of not being able to cope with the reduction in the space between switches. However, if you forcibly reduce the space between the switches, the number of arms will decrease and appropriate elasticity will not be obtained, so just remove the arm and heat-melting layer and insert the push button into the panel surface. The following methods are used. In this case, it is necessary to assemble the letters printed one by one from the back side of the panel so as not to confuse the placement of the letters, which can lead to problems such as the board falling apart and the push buttons falling apart due to malfunctions. Ta.

This invention was made to solve the above-mentioned problems, and it is possible to reduce the space between switches and correspond to light intensity, and it also makes maintenance easier because each push button does not come apart during assembly and disassembly. [Means for solving the problem] A panel switch mechanism according to the present invention is one in which a plurality of push buttons are integrated and connected to the extent that adjacent push buttons do not interlock with each other. It is.

[Effect]

Since the panel switch mechanism according to the present invention has a plurality of push buttons connected and integrated, assembly can be easily performed while maintaining the same switch arrangement. Also, since multiple push buttons are connected, if appropriate elasticity cannot be obtained and pressing one push button causes the adjacent button to also operate, cutting the connecting band after assembly will solve the problem. It disappears.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of the panel switch mechanism, and FIG. 2 is a plan view of the push button switch section thereof. In (2), l is a push button, and the adjacent push button is a thin connecting strip 1
Connected by a. Nowadays, many push buttons are made of grease-resistant molded products, and this thin connecting band 1a can be used as is during molding. The push buttons 1 are inserted into openings 4a arranged in the panel 4. Note that the other details are the same as before.

Its operation consists of pressing push button 1 and tact switch 2.
is pressed and returns to its original state due to tWT and the spring force of the tact switch.

Note that even if the push button l and the panel 4 are thermally fused by extending the connecting band 1a further outward, the same effect can be obtained as long as there is no interlocking between the adjacent buttons due to the rigidity of the connecting band. .

Next, FIG. 8 shows another embodiment of the present invention, in which a plurality of push buttons 1 are connected by a film sheet 8 at the viewing part 8a, and in this case, since it is a film sheet, Rigidity is low, so adjacent push buttons are 1 even when connected! ! Unable to move, disconnect after assembly! This eliminates the need for four-tool work, reliably prevents push buttons from falling apart during maintenance in the event of a failure, and facilitates assembly.

Furthermore, as in the film sheet 8 shown in FIG. 4, the opening size of the push button positioning hole 8b is made to fit with the protrusion of the push button 1, making it difficult for it to come off, thereby eliminating the need for adhesion and making assembly easier. becomes easier.

〔Effect of the invention〕

As described above, according to the present invention, since the push button is integrated, it is possible to obtain a panel switch that is easy to assemble and compact.
