Abstract

PURPOSE: To establish the tape end detection set of low cost with a simple constitution, by the constitution that the lever is momentarily turned when the tape reaches its end at tape fast feed or rewinding.
CONSTITUTION: When the tape reaches its end at face feed and the reel 41 stops, or when the tape reaches its end at rewinding and that reel 42 stops, the rotation of the follower idler 4 in contact with any of them stops and the rotation detection idler 7 is immediately stopped via the rotary shaft 33, belt 8 and pulley 72. On the other hand, the idler 3 in contact with the flywheel 2 is turned and torque is delivered to the sub-idler 5, then the sub-idler 5 turns along the external circumference of the roation detection idler 7. Thus, the support lever 6 of the sub-idler 5 is turned against the spring 62 and the end of tape can be detected. Thus, the tape end detection set of low cost with a simple constitution can be obtained.
