<p>PURPOSE:To make whole device thinner by overlapping a 2nd protective cap, a tape traveling guide and a part of structural member in a plane parallel to the reference surface for placing the cassette at the time of cassette loading. CONSTITUTION:The arrangement relation a guide roller 7, 1st tape protective cap 2b, and 2nd tape protective cap 2c, in the state that the tape loading is completed, is shown in the figure. At this stage, by overlapping a dead space (sand dotted part) where a part of weight 7c of the roller 7 is surrounded by the caps 2b, 2c, the outside diameter of weight 7c can be made larger and a moment of inertia is saved. Thus, by housing a part of the weight 7c in the dead space generated from the movement of protective caps, the projecting area of a tape path is reduced without harming the moment of inertia of roller 7, then a compatibility for the miniaturization of mechanism limit and the lowering of jitter is attained.</p> |
