Abstract

PURPOSE:To prevent the mechanism of the entitiled system from being kept locked status for a long period and shorten the detecting time of a hub end more quickly than that of reproduction by generating a hub end detecting output quickly by the stop of rotation of a reel board. CONSTITUTION:The circumference of a magnet 1 is magnetized by N and S poles respectively and the magnet 1 is mechanically coupled with a driving mechanism M and rotated by the rotation of a reel board. A hole element 2 generates a pulse according to the rotation of the magnet 1. An output from the hole element 2 is inputted to a control circuit 4 through a line 3. The control circuit part 4 connects control such as reproduction, quick sending or rewinding to the driving mechanism through a connection 5.
