<p>PURPOSE:To miniaturize a tape ejection mechanism by loading a tape without contacting a guide at a region having a small curvature of a guide path and providing a tension servo mechanism to prevent damages to the tape. CONSTITUTION:A gear arm 14 is turned along a cam slot 15a by rotation of a drive gear 15, a tension arm 10 is driven by the gear and a tension pin 9 extracts the tape 2 from the inside of the cassette 1. Then the pin 18a is brought into contact with and in the guide slot 17 and a tape guide 3a is moved, since the tension pin 9 takes precedence over it, a taper pin 8a of the tape guide 3a is out of contact with the tape 2 to prevent elevation of the tape. When the tape 2 is loaded on a prescribed position, the energizing force of an elastic body 13 is exerted to the tension arm 10 to start the tension servo mechanism. Thus, damages to the tape due to the elevation of the tape by the paper pin 8a are avoided and the mechanism is miniaturized.</p> |
