<p>PURPOSE:To prevent the damage of a tape, by performing rapid-traversing and rewinding operations in the state where the tape is pulled out to the position where the tape faces a tape end sensor and does not come into contact with a guide cylinder. CONSTITUTION:When the rapid-traversing or rewinding operation is performed in the unloading state, a loading disc 3 is turned slightly counterclockwise and is stopped. At this time, the second turning lever 25 is turned counterclockwise by sliding of a roller 25b on a cam face 3d of the loading disc 3, and the first turning lever 22 and a back tension lever 20 are turned clockwise in accordance with this turning of the second turning lever 25, and therefore, a back tension pin 21 pulls out a tape 4 from a take-up reel in a cassette 5 and is stopped in the operation position. In this state, the tape 4 faces tape end sensors 28 and 29 in the supply side and the take-up side.</p> |
