Title: Tape end detector
Inventor: KURAFUJI TAKAMASA
IPC: G11B15/093
Filed: 1982-02-09
Abstract: PURPOSE:To simplify the structure of a tape end detector, by allowing a detecting member to moves a fulcurm of displacement and vary a displacement range, when engaging the engagement part of a cam part on detecting a body of revolution stopping rotation. CONSTITUTION:The tape end detector moves the fulctrum of displacement of a detecting level 25 as the detecting member and then varies the displacement  range when the detecting lever engages the engagement part 18b of the cam  member 18 on detecting a reel turntable 22 as the body of revolution stopping  rotation in relation to a run of a tape. Therefore, the detecting lever 25 detects  the end of the tape to be displaced greatly without depending upon the shape of  the engagement. Thus, a lock mechanism is given an enough resetting stroke and consequently while the operation is secured, mechanism of a special member is unnecessary, thereby simplifying the structure.
