のとき選局周波数を可変して自動選局を行なう電
子同調チユーナであつて、自動選局動作時の同調
指示電圧を相対的に非自動選局動作時の同調指示
電圧より低下せしめる回路を設けてなる電子同調
チユーナ。 An electronic tuning tuner that performs automatic tuning by varying the tuning frequency when the tuning command voltage corresponding to the receiving sensitivity is less than a predetermined voltage, and the tuning command voltage during automatic tuning operation is relatively non-automatic tuning. An electronic tuning tuner equipped with a circuit that lowers the tuning instruction voltage during operation.
