<p>PURPOSE:To attain miniaturization and to prevent impairment of balance and a malfunction of a flywheel by having such a constitution where a pressure projection part has a contact with a contact part in case a detached state lasts between the contact part of a cam follower and the cam surface and then a revolution transmitter works to actuate a pinch roller switching mechanism. CONSTITUTION:When a tape is completely taken up to a right reel, a friction mechanism set between a large gear 26a and a reel shaft 1a generates a slip. Then the shaft 1a stops and a contact part 33a is detached from a cam surface 11a at a position where the part 33a has the shortest distance from a shaft 10a. Thus a pressure projection part 12a has a contact with the part 33a, and a rotary plate 7a turns against a spring 27a to separate a gear 9a from the gear 26a. Thus the transmission of revolving power to the gear 26a is cut off. While a node action plate 25 energizes and turns a development spring 22 clockwise and shifts quickly a switch plate 17 to the left side.</p> |
