なる押しボタンダイヤル入力回路。 A key of the key matrix is turned on by a corresponding push button to drive a dial control section, and a control signal corresponding to the operated push button is inputted from the dial control section to a dial signal sending circuit. In the push-button dial input circuit, in which the dial signal is sent to the line from the dial signal sending circuit, a key is operated when the control unit does not desire to accept the key input. A push-button dial input circuit comprising prohibition means for prohibiting key input to the dial control unit even if the dial control section is pressed.
