ABSTRACT:
A tape drive mechanism for a tape recorder is provided with a motor-driven drive gear. The tape drive mechanism includes first and second switch gears engageable with the drive gear for respectively switching the tape drive mechanism into a first and second mode of operation. First and second cam arrangements respectively convert the rotation of the first and second switch gears into a displacement of the magnetic head of the tape recorder relative to the magnetic tape. The drive gear when switched to the first mode displaces the magnetic head by the first cam arrangement, and when switched to the second mode displaces the magnetic head by the second cam arrangement. The first and second switch gears are each provided with a toothless portion for disengaging the drive gear in the first and second modes of operation respectively. First and second trigger mechanisms respectively retain the first and second switch gears in position in the first and second modes and also function to switch the tape drive mechanism into additional modes of operation.
