<p>PURPOSE:To engage and disengage a tape drawer body without requiring strong pressing force, by loading and unloading the tape drawer body interposing a prescribed arm, and a cam plate, when the tape drawer body is fixed on a fixed body. CONSTITUTION:An arm 55, and the cam plate 59 are supported in such a way that they can turn freely, on shafts 63 and 64 in the neighborhood of the fixed body 19 of a base 5, and they are pressed by springs 60 and 61, respectively. When a motor 19 is driven to draw out a tape, the pole 50 of the drawer body 9 presses the cam plane 59a of the cam plate 59, and releases the prohibited state of the turning of the arm 55, therefore, the pole 50 is locked by the hooking part 55a of the arm 55, then being fixed. Also, when fixing is released, since a connector pin 37 rotates the cam plate 59, the pole 50 is separated, thereby, the fixing is released. In this way, it is possible to engage and disengage the drawer body without requiring the strong pressing force for the fixing.</p> |
