ABSTRACT:
A device for use in a tape driving apparatus for detecting the tape end made of transparent material, comprising means for generating signals consisting of a first output and a second output having a delay time behind the first output, a device for emitting light upon the existence of the second output, a sensor for receiving the light emitting from the light emitting device through the tape end of transparent material, and a discriminating means for controlling, by means of the first output, the output supplied from the sensor during the existence of the second output, whereby the tape end is correctly detected without causing trouble in connection with extraneous light to be introduced from the outside.
