The telephone body 51 is always in an OFF-HOOK state. In order to prevent this, in the past, in order to turn the switch 55 on and off,
Another handset that is not connected to the telephone main body 51 is used as an alternate, and the handset is moved each time it is used. Conventionally, as another method, a hook switch 60 is provided on the headset 57 side as shown in FIG.

Problems to be solved by the invention However, the former had the problem of being cumbersome to operate. Also, in the latter case,
Since it is necessary to provide the switch 60 in parallel with the circuit of the switch 55 of the telephone main body 51, it is necessary to modify the telephone main body or to provide a terminal 61 necessary for headset in advance on the modular connector 56. In order to be able to connect the headset 57 to any telephone set, there were problems such as being economically disadvantageous.

Therefore, the present invention is designed for users who use their phones frequently.
In addition, when using both hands for other purposes during a call, the user can easily operate the switch, and the adapter does not require modification of the phone, making it economically advantageous. This is what we are trying to provide.

Means for Solving the Problems The technical means of the present invention for solving the above problems consists of an adapter case that is removably attached to the handset recess on the hook switch side of the telephone body, and a device that is supported by the adapter case. The device is equipped with an operating member for mechanically switching the switch on and off, and a positioning means for positioning the operating member in the ON and OFF states of the switch.

Effects The present invention has the following effects due to the above configuration.

The operation member of the adapter attached to the handset recess on the side of the hook switch allows you to operate the hook switch.
You can turn it on or off, so when you use a headset, you don't have to go to the trouble of turning the handset on or off.
There is no need to use it just to turn it off, there is no need to prepare a special weight, and there is no need for a circuit or terminal for the switch operation.
