<p>PURPOSE:To simplify the unit constitution and to ensure the operation, by mounting or demounting the tape container including the release of lock of housing, through one revolution of the rotary body turned with the rotary drive source. CONSTITUTION:When the video cassette 34 is inserted in the cassette housing 1 toward the arrow A, the slide plate 4 moves the roller 7 along the horizontal part 8a of the guide long hole 8 toward B. When the roller 7 reaches the curved part of the long hole 8, the cassette 34, housing 1 and slide plate 4 are down with gravity, the roller 7 is locked with the lock arm 7, and the cassette 34 is locked to the mounting position. Further, when the detaching signal is received, the motor 15 starts and the lock of the roller 7 is released with the rotation of the rotary body 20 and the arm 12 is turned counterclockwise. Thus, the roller 7 goes upward along the long hole 8 and stops at the end of the horizontal part 8a. Thus, the holder 1 moves up toward B and the cassette 34 is detached.</p> |
