Claims

[Scope of utility model registration request]

An auto-reverse mechanism for a magnetic recording and reproducing device includes: a driving force switching means for a reel base; a means for detecting rotation stoppage of the reel base; a means for rotating a power gear having an intermittent gear in response to the detection means; A means for operating the driving force switching means and the change plate by rotation of a power gear, and a spring for rotatably supporting two pinch rollers and applying a bias force to the pinch roller in a direction in which the pinch roller is always pressed against the capstan shaft. and a rotatable support means, the change plate is provided with two holes having slopes, and movement of the change plate causes the support means to rotate on the slope against the bias of the spring. An auto-reverse mechanism characterized in that the pinch roller is separated from the capstan shaft, and the reaction force applied to the slope at this time draws the power gear to engage the intermittent gear with another gear.
