<p>PURPOSE:To secure the shift space of a loading arm and to attain the effective use of the space by engaging the right and left loading gears with each other via a coupling gear. CONSTITUTION:The coupling pin 2a of a cam plate 2 is engaged with the groove can 1a of cam gear which is driven by a loading motor. A tip gear 2b engages a right loading gear 3R and this gear 3R is connected to a left loading gear 3L via an intermediate gear. In a loading mode the gear 1 is revolved and both gears 3R and 3L are revolved via the plate 2. Then loading blocks 8R and 8L and a guide post 22 move forward to load a tape. In such a constitution, the shift spaces are secured for both loading arms 6R and 6L and can be used effectively.</p> |
