PURPOSE:To simplify the loading mechanism and to make the titled device small-sized, by constituting a loading arm with an elastic plate spring capable of deformation and absorbing the over stroke of the loading arm. CONSTITUTION:At the loading mode, a loading motor (not shown) is turned and a pin 5 of a sector gear 15 is turned around a shaft 16 in interlocking with a loading cam. A shaft 28 is turned via a shaft 17 and gears 18 and 19 in interlocking with this turning and a shaft 26 is also turned via a shaft 27 and gears 20 and 21. The shafts 28 and 26 support loading arms 23 and 25 consisting of two elastic plate springs 23a and 23b, and 25a and 25b, freely rotatably, the loading arms 23 and 25 are bent and extended and a loading block (not shown) fitted at the tip of the arms loads or unloads the tape. Thus, the plate springs absorb over-stroke, allowing to simplify the loading mechanism and to make the device small-sized. |
