ダのモータ駆動回路。[Claims for Utility Model Registration] In a tape recorder in which a magnetic head moves to a position where recording or playback is possible by the rotation of a motor serving as a drive source for a tape reel, driving power supplied from a power supply unit to the motor is turned on. It is characterized by comprising a switching element for off-controlling, and a time constant circuit for supplying an operation start voltage of the switching element after the recording or playback amplifier reaches steady operation in response to the on-operation of the power supply section. motor drive circuit for a tape recorder.
