Claims

[Scope of utility model registration request]

A reversing plate that slides between two positions to switch between normal rotation and reverse rotation, an assist cam having a toothless portion and rotated by a motor, and a rotation fulcrum that engages with the engaging portion of the reversing plate. a switching plate having first and second contact pieces on both sides thereof, a sliding contact portion that slides in contact with the assist cam, and first and second contact portions that selectively face the first and second contact pieces. It includes a reversal control plate and a spring suspended between the reversal plate and the reversal control plate, and depending on the position of the reversal plate, the first abutting piece and the first abutting part or the second abutting piece and the second abutting piece are provided. A running direction switching mechanism for a tape recorder configured to select contact with an abutting part, and switching to reverse running when running in the forward direction and switching to normal running when running in the reverse direction.
