を特徴とするテープレコーダ装置。 A cam gear for driving and controlling a tape recorder mechanism, a driving means for driving and controlling the cam gear, a control member for controlling the cam gear to an engagement position and a non-engagement position in which the cam gear is engaged with the driving means, and a biasing means for biasing the control member in a direction in which the cam gear engages the drive means; and a biasing means for driving the control member;
An electromagnet is arranged opposite to a permanent magnet having a magnetic force that attracts the control member against the biasing means, and cancels the magnetic force of attraction using a drive signal to cause the control member to be attracted to the biasing member. an electromagnetic means that acts so as to be actuated by a biasing means, and an electromagnetic means that acts on the electromagnet of the electromagnetic means in the direction of canceling and attracting the permanent magnet in the movement process from an operating position where the cam gear is rotationally driven to a stop position. and a drive circuit that controls the control member by supplying forward and reverse currents so as to generate magnetic force.
