Claims

[Scope of utility model registration request]

A rewind operation member that moves forward when a rewind button attached to one end is pushed in and a fast forward operation member that moves forward when a fast forward button attached to one end is pushed in are arranged parallel to each other for recording or playback. When one of the operating members moves forward by a predetermined head push-back amount in the rewind mode, the magnetic head retreats from the recording or playback position, and the rewind operating member moves forward by a direction switching amount that is less than the head push-back amount. actuating the tape running direction reversing mechanism when the tape passes the position in the forward or reverse direction, and when either of the operating members moves forward by a mode setting amount that is greater than the amount of pushing back of the head, the operating member is activated. The device is locked in its forward position by a locking mechanism, and this locking is released when the other operating member moves forward by a locking release amount that is smaller than the direction switching amount, and the original recording or playback mode is restored. In the mode switching operation device for a tape recorder, each of the operating members is provided with a pushing part and an abutting part, and a movement amount regulating body is provided near both of the operating members, and this movement amount regulating body is provided. an elastic member that elastically holds the abutting portion of either of the operating members at a neutral position that is out of the forward movement path; The movement amount regulating body is moved from the neutral position to the forward movement path of the contact portion of the other operation member by the pushing away portion of the operation member, and the forward movement amount of the other operation member is controlled by the locking portion. A mode switching operation device for a tape recorder, characterized in that the mode switching operation device for a tape recorder is limited to an amount that is greater than the release amount and less than the direction switching amount.
