Abstract
A tape end detecting device for detecting the end of the tape enclosed within a cassette includes a light emitting element for generating a light pulse signal, a pair of light receiving element, a light guide means comprising a central prism and a pair of side prisms disposed at both sides of said cassette loaded in position, and a tape end signal generating circuit adopted for generating a tape end detecting signal only when it receives the light pulse signal. Therefore, the tape end detecting device operates to generate an output upon receipt of the light signal, but does not generate when the light coming from outside is received.
