Claims

[Scope of Claim for Utility Model Registration] A tape recorder that rotates a motor forward during playback and reversely rotates the motor during rewinding, a drive gear to which rotational force is applied by the motor, a locking protrusion, and a toothless portion. a driven gear having an end portion that engages with a locking protrusion of the driven gear, and a spring that locks the toothless portion of the driven gear in a position facing the drive gear. The rotationally energized locking lever is energized by a spring with a force weaker than the force of the spring that biases the locking lever in order to cause the driven gear to mesh with the drive gear 8 through the toothless portion. a starting lever that operates under suction during a regeneration operation and rotates the locking lever in the other direction against a spring to disengage an end of the locking lever from the locking protrusion of the driven gear; and a head support plate that moves forward in relation to the rotation of the driven gear, and when the driven gear is engaged with the driving gear by the activation lever, if the driving gear is rotating, the driven gear is engaged with its locking protrusion. A head of a tape recorder characterized in that the toothless part of the stop leg is configured to rotate back to a position facing the drive gear by the spring force of the lever. Support plate control device.
