An object of the present invention is to solve such a problem. In the telephone of the third embodiment, even if the extension portion is expanded and contracted with respect to the main body, the electrical connection between them is changed. It is an object of the present invention to obtain a telephone having no electrical connection structure.

[0007]

In order to solve the above-mentioned problems, in the telephone according to the present invention, the telephone receiver or the extension unit having the transmitter can slide with respect to the main unit having the transmitter or receiver. The extension is provided with a plurality of mutually connected electrical connection contacts, and the main body portion has a common electrical connection contact with the plurality of electrical connection contacts. And an electrical connection contact of the extension portion is connected to an electrical connection contact of the main body portion in a state where the extension portion is stored in the main body portion and in a state where the extension portion is slid and extended. The above-mentioned problem has been solved by using a passive contact structure.

Therefore, the telephone according to the present invention can be shortened in its overall length, and can be electrically connected to the main body and the extending portion when the telescopic device is expanded and contracted with a very simple structure, a minimum area, and without change. .
