<p>PURPOSE:To perform proper operations with a simple mechanism by providing the interlocking gear operating mechanism which loads a tape pack adequately by utilizing the driving force of a motor. CONSTITUTION:When tape pack 90 is being loaded, cam hole 75a of gear lock piece 75 activated by spring 81 engages gear 58 with worm 52 perfectly and the rotation of worm 52 driven by motor 20 is transmitted to rack plate 65 to draw tape pack 90. On the loading operation, ejection plate 70 rotates lock-off plate 74 to push gear lock piece 75 forward, and then gear 58 is disengaged from worm 52. In ejection, adsorption plunger 86 is turned off to rotate power lock piece 73 counterclockwise, and lock-off plate 74 operates to disengage gears 52 and 58 from each other, so that gears 52 and 58 will remain disengaged from each other until the completion of the ejection.</p> |
