Apparatus for detecting the end of a magnetic tape.

摘要

Apparatus including a magnetic tape (4) having transparent lead tapes connected at both ends thereof which extends between a feed reel (1) and a take-up reel (3) in a cassette (1); a light receiving elpment (36) is incorporated into a positioning pole (7) located in said cassette (1) when the cassette (1) is in an operative position, whereas a light emitting element (38) is provided outside the cassette (1) at a point opposite to said light receiving element (36) and across said magnetic tape (4) interlaid between these two elements (36, 38). In this way, the two elements (36, 38) are adapted to detect the lead tape at the end of said magnetic tape (4).
