(Pressing operation of operation button)
Next, a state when the user operates the operation button 2 in the pressing direction will be described.
First, when the user operates the upper button 2a at a position adjacent to the middle button 2b in the pressing direction with the operation button 2 mounted on the button mounting portion 8, as shown in FIG. 8, the upper button 2a presses backward. Then, the middle button 2b also tries to sink backward in conjunction with the connecting piece 10, but the middle button 2b comes into contact with the connecting side boss 20a to prevent it from sinking deeply in the rear direction. Since the movable portion 22 can be prevented from moving backward by the pressing pin 15 of the middle button 2b and coming into contact with the switch 23 of the control board 9, the switch of the control board 9 is prevented by the pressing pin 15 of the upper button 2a and the middle button 2b. It is possible to prevent the microcomputer from determining an error when the 23 is pressed at the same time.

Here, when the housing in which the operation buttons are mounted on the button mounting portion is transported by a truck or the like, as shown in FIG. 10, the connecting piece 50 is broken by the vibration of the transportation, and one of the adjacent operation buttons 51 and the other are adjacent to each other. There is a possibility that the connecting piece 50 is divided by the operation button 52, and when the user presses one operation button 51 while the connecting piece 50 is broken, the connecting piece 50 of one operation button 51 operates the other. There was room for improvement because the button 52 was fixed in a state of being sunk behind the connecting piece 50, and one of the operation buttons 51 could not be returned to the original state while being pressed down.

In the present embodiment, when the user operates the upper button 2a at a position adjacent to the middle button 2b in the pressing direction, when the upper button 2a sinks backward, it comes into contact with the connecting side boss 20c of the button mounting portion 8 and further. Since the sinking in the rear direction is prevented, when the housing 1 is transported by a truck or the like, even if the upper button 2a is pressed while the connecting piece 10 is broken due to the vibration of the transportation, the upper button 2a Is deeply sunk in the rear direction, and the broken connecting piece 10 of the upper button 2a is fixed in a state of being sunk behind the connecting piece 10 of the middle button 2b. It is possible to prevent the product from returning to the position.

Further, as shown in FIG. 9, when the user operates the upper button 2a which is not adjacent to the middle button 2b at the upper end of the button mounting portion 8 in the pressing direction, when the upper button 2a sinks backward, the upper button 2a becomes a button. Since it comes into contact with the fixed side boss 21a of the mounting portion 8 and further sinking in the rear direction is prevented, the upper button 2a on the side near the upper end of the button mounting portion 8 sinks deeply, and the translucent protrusion 11b is fixed. Each of the piece 12, the left claw 13, and the right claw 14 is tilted and caught on the opposite end faces of the fixed piece connection hole 17, the left claw connection hole 18, and the right claw connection hole 19, and the upper button 2a is pressed. It is possible to prevent the sinking backward and not returning to the original position.

In the present embodiment, the prevention of sinking in the rear direction when the upper button 2a is operated in the pressing direction at a position adjacent to the middle button 2b or near the upper end of the housing 1 has been described, but the lower button 2c has been described. Similarly, when the lower button 2c at a position adjacent to the middle button 2b is pressed by the user, the middle button 2b linked by the connecting piece 10 is prevented from being deeply sunk backward by the connecting side boss 20b. As a result, it is possible to prevent the switch 23 of the control board 9 from being simultaneously pressed by the middle button 2b and the lower button 2c.

Further, the lower button 2c is prevented from being deeply sunk in the rear direction by the connecting side boss 20d, so that the lower button 2c is pressed while the connecting piece 10 connecting the middle button 2b and the lower button 2c is broken. Then, the connecting piece 10 on the lower button 2c side is fixed in a state of being sunk behind the connecting piece 10 on the middle button 2b side, and the lower button 2c is sunk in the rear direction and does not return to the original position. Can be prevented.

Further, when the lower button 2c that is not adjacent to the middle button 2b is pressed at the lower end of the button mounting portion 8, when the lower button 2c sinks backward, the lower button 2c becomes the fixed side boss 21b of the button mounting portion 8. Since the lower button 2c near the lower end of the button mounting portion 8 sinks deeper than the middle button 2b side because it abuts and prevents further sinking in the rear direction, the fixing piece 12, the left claw 13, and the left claw 13 Each of the right claws 14 is inclined toward the lower end of the button mounting portion 8 and is caught on the opposite end faces of the fixed piece connection hole 17, the left claw connection hole 18, and the right claw connection hole 19, and the lower button 2c is pressed. It is possible to prevent the sinking backward and not returning to the original position.

As described above, when the user operates the upper button 2a or the lower button 2c at a position adjacent to the middle button 2b in the pressing direction while the operation button 2 is mounted on the button mounting portion 8, the connecting piece 10 interlocks with the upper button 2a or the lower button 2c. The middle button 2b tries to sink backward, but the connecting side boss 20a or the connecting side boss 20b prevents the middle button 2b from sinking deeply in the rear direction. The interlocking middle button 2b puts the switch 23 of the control board 9 in a state of being pressed at the same time, and it is possible to prevent the microcomputer from determining an error.

Further, when the user operates the upper button 2a or the lower button 2c adjacent to the middle button 2b in the pressing direction, the connecting side bosses 20c and 20d prevent the upper button 2a and the lower button 2c from sinking deeply in the rear direction. Therefore, even if the upper button 2a or the lower button 2c is pressed while the connecting piece 10 is broken due to vibration during transportation, the connecting piece 10 on the upper button 2a or the lower button 2c side is the middle button 2b. It is possible to prevent a situation in which the upper button 2a or the lower button 2c does not return to the original position because the upper button 2a or the lower button 2c is fixed in a state of being sunk backward from the connecting piece 10 on the side.

Further, when the upper button 2a not adjacent to the middle button 2b is pressed at the upper end of the button mounting portion 8 or the lower button 2c not adjacent to the middle button 2b is operated at the lower end of the button mounting portion 8 in the pressing direction. Since the fixed side bosses 21a and 21b prevent the upper button 2a and the lower button 2c from sinking deeply in the rear direction, the fixed piece 12 and the left claw 13 of the upper button 2a or the lower button 2c are fixed piece connecting holes. 17. It is possible to prevent a situation in which the left claw connection hole 18 is caught and does not return to the original position.

Further, the other configurations used in the present embodiment are presented as an example, and are not intended to limit the scope of the invention, and can be implemented in various other embodiments. Various omissions, replacements, and changes can be made without departing from the gist of. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.
