Claims

[Scope of utility model registration request]

(1) A pair of left and right cams are provided on the roller change plate that reciprocates by the channel change mechanism, and the left and right pinch rollers are engaged with these cams, and the roller change plate is locked in the left and right positions when the power is turned on. In a tape player, the pinch roller is pressed against the capstan shaft by bringing the crimping portion of one of the cams closer to the pinch roller side, and two release plates that engage with the roller change plate are provided, and the roller By engaging the engaging portion provided on the change plate with the pressing portion provided on each release plate, one of the release plates is linked to the left and right movement of the roller change plate, and both of the release plates are provided between these release plates. A pinch roller release mechanism is provided with a spring that biases the pressing parts toward each other.

(2) A patent in which the channel change mechanism uses a power gear rotated by a motor, a power plate and a roller change plate interlocked with the power gear, and the power plate has a relief part at the engagement part with the power gear. A pinch roller release mechanism according to claim 1.
