Description

  The present invention relates to an emergency call button device that is provided in an emergency call device that reports an emergency or emergency situation to a police, a security company, or the like via a line and that is pressed in an emergency or emergency.

  In this type of emergency call button device, the police and the security company will be confused if an error is reported even though an emergency or emergency has not occurred. The protective cover is supported via a support part that can be broken when it is strongly pressed without moving to the extent that it accidentally contacts the protective cover. Therefore, when an emergency or emergency occurs, the support portion is broken by pressing the protective cover strongly, and the switch is turned on by moving the protective cover. In such a configuration, even when an emergency call is made at the time of maintenance and inspection, the support portion of the protective cover must be broken, which necessitates replacement of the protective cover, which is uneconomical. In addition, since the broken support portion is scattered in the apparatus housing, there is a problem that the operation of removing the support portion is complicated.

In order to solve this problem, conventionally, a small through hole is provided in the center of the protective cover, and a switch is turned on by inserting a pin from the through hole instead of pressing the protective cover during maintenance inspection. (For example, refer to Patent Document 1).

  In the conventional emergency call button device described above, the diameter of the through hole needs to be formed as small as possible in order to restrict erroneous notification due to insertion of something other than a pin in the through hole. The pin to be inserted is also formed with a thin diameter. As described above, since the switch is pressed by the pin formed with a thin diameter, the pressing operation of the switch by the pin becomes unstable, and the workability of the maintenance inspection is lowered. In particular, when the switch is made of a rubber sheet to reduce the thickness of the device, the workability is significantly reduced, and the rubber sheet may be damaged by the tip of the pin, reducing the durability of the switch. There was also a problem of making it happen.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to improve the workability of maintenance inspection and the durability of the switch.
