発生回路を有する電話機において、前記゛ダイヤル信号
発生回路のリセット信号を制御するリセット回路入力に
コンデンサーを橋絡し、局線回路の負側にフックスイッ
チを挿入しフックスイッチのトランスファ接点が、オン
フック時には前記コンデンサーを短絡してリセット回路
は即時にリセット信号を出力し、オフフック時には前記
コンデンサーの短絡を解除して局線回路の瞬断の間リセ
ット回路入力の電圧を保持するように構成したことを特
徴とする電話機回路。In a telephone that has a dial signal generation circuit with a redial function or a memory function, a capacitor is bridged to the reset circuit input that controls the reset signal of the dial signal generation circuit, and a hook switch is inserted on the negative side of the central office line circuit. The transfer contact of the hook switch short-circuits the capacitor when on-hook, and the reset circuit immediately outputs a reset signal, and when off-hook, the short-circuit of the capacitor is released and the reset circuit input voltage is maintained during a momentary interruption of the station line circuit. A telephone circuit characterized in that it is configured to hold.
