For example, as described in Patent Document 1, such a push button is often provided with a separate push button for each switch provided for each function such as its own setting or calling of another device. On the other hand, a so-called cross button has been devised as one push button capable of turning on / off a plurality of switches.

JP 2005-228590 A

  However, as disclosed in Patent Document 1, if a separate push button is provided for each switch, the number of push buttons increases as the number of switches increases, that is, the number of functions increases. Therefore, the number of parts increases, causing problems such as high costs and complicated assembly work. On the other hand, when the cross button is adopted, in order to turn on / off different switches, a complicated support structure for enabling the cross button to tilt in four directions (for example, up, down, left, and right directions) is required. In addition, since such a cross button is generally apt to be small, there is a problem that it is difficult to adopt as a call button which is a basic button in a telephone device in terms of operability and visibility.

  Therefore, the present invention has been made in view of the above problems, and it is possible to reduce the number of members without reducing the number of switches that can be turned on / off, and to provide a communication device that can be configured with a simple structure.

According to this configuration, two or more different switches can be turned on / off with one push button. Therefore, the number of parts can be reduced as compared with the conventional case where a separate push button is provided for each switch. In addition, since the operation unit is merely used between the fulcrum and the fulcrum, the configuration for enabling the operation of a different switch is simple compared to the cross button conventionally employed. Therefore, cost reduction and simplification of assembly work can be achieved. Further, unlike the cross button, it can be formed in a large size, and can be employed as a button for turning on / off a call function which is a basic push button in a call device.

According to a second aspect of the present invention, in the first aspect of the present invention, there is provided a regulating rib protruding rearward on the outer periphery of the push button, and when the operation portion is pushed in, the regulating rib becomes a front surface of the front case.
