Abstract

PURPOSE: To obtain a high-reliablility detector of simple constitution which provides definite detection, by controlling the switching of a switch by a detection lever provided to a fluid clutch coupled with a body of revolution turing interlocking with a tape run.
CONSTITUTION: Supply reel turntable 3 is rotated by power which is frictionally transmitted through rotary pulley 6 and felt 4 pushed by constant pressure of spring 7. Its rotations are transmitted to detection lever 9 constituting a fluid clutch coupled with the outer circumference of bearing part 10 of turntable 3 through a viscous fluid such as grease and so far as turntable 3 is rotating, lever 9 is displaced to close lead switch 18. When turntable 3 where a tape end is fixed is forced to stop rotating at the tape end, rotation force transmitted from turntable 3 disappesrs, lever 13 is reset by the elastic force of spring 12 and the lead switch is turned ON and OFF once by a simple constitution, so that the tape end can definitely be detected with high reliability. The same result can be obtained by controlling the switch by a permanent magnet provided to the detection lever.
