Abstract

PURPOSE:To realize detection of high reliability, by unifying the detecting mechanisms for presence or absence of a reel lock ring and a write permission ring. CONSTITUTION:A reel lock detecting ring 9 that has a displacement by the operation of a handle 16, and a lock detecting switch 10 is provided at the position to have no contact to the ring 9 during a reel locking mode and detects the displacement of the ring 9. A write permission ring detecting ring 17 is connected to the ring 9 and has a projection which can be fitted to a position corresponding to the write permission ring insertion groove 3 of a magnetic tape reel 1. In addition, the write permission ring detecting switches 18 and 19 are provided at the position where no contact is given with a write permission ring 4 in a reel locking mode and detect the displacement of the ring 17.
