<p>PURPOSE:To stabilize a catching without being influenced by a change of a loading motor torque by installing a constrained part at a tape pull-out means, and constraining mechanically this with constraining members installed at an end of the loading. CONSTITUTION:When a guide post unit 14 approaches a loading end, a slope 24 of a cam plate 21 installed at the unit 14 abuts on a catching roller 29 of a catching unit 25 and make a progress as it does. For that reason, the catching roller 29 is pressed in the B direction of an arrow by the slope 24. The pressing force overcomes an energizing force of a coil spring 30 and a catching unit 28 is opened in the outside direction. A progressing force of the cam plate 21 functions as a wedge effect of the slope 24 and an oscillating plate 28 is easily opened. At a loading completing position, the catching roller 29 is engaged with a recessed part 23 of the cam plate 21 and the catching is executed. By such a constitution, the stable catching can be always executed without being influenced by the variation of a loading motor torque.</p> |
