Abstract
PURPOSE: To enable to accurately control a rotary body, by controlling the rotation and stop of the rotary body with the output of sensors provided at a prescribed position, in the access of a sheet recording and playback device.
CONSTITUTION: Sensors 9, 10 are located at the positions where switching is made when a motor 1 rotates and a light shield disc 7 is turned with the rotation of an access shaft 3. The direction of rotation and revolution are controlled with signals E, F from a control section 19 for a rotation switching section 18 including the motor 1, and stop control is made with a signal G. Signals A, B from switching sections 20, 21 by the sensors 9 and 10 are given to a control section 19. A signal I produced every one revolution of the disc 7 is counted 22, and further, the access location input from a key entry 23 is counted 25 via a converter 24, both the counting values are compared 26, and signals C, D for start/stop fast forwarding/rewinding are given to the control section 19.
