ープレコーダーのテープ速度制御回路。 In a tape recorder configured to be able to vary the playback speed of a magnetic tape by varying the rotational speed of an electric motor, a motor drive circuit that rotationally drives the electric motor and controls the rotational speed; a variable resistor, which is equipped with a slider and a center tap that are slidably displaced by an operating knob that changes the playback speed, and whose resistance value sets the rotational speed of the motor by the motor drive circuit; It consists of a speed selection switch that can be switched between a playback speed variable position and a constant speed position, and when the speed selection switch is in the constant speed position, the resistance value obtained from the center tap provided on the variable resistor is A tape speed control circuit for a tape recorder, characterized in that the electric motor is driven to rotate at a rotational speed set by the control knob, thereby making the playback speed of the magnetic tape a specified speed regardless of the position of the operating knob. .
