Abstract
PURPOSE:To equalize all the movement intervals, by moving a typing head etc. back under the reverse drive of the pulse motor and by moving the typing head beyond a predetermined point and thereafter moving the typing head back when stopping it at the predetermined point. CONSTITUTION:The typing head 4 attached to a wire 3 between pulleys 1, 2 is moved while the pulse motor 5 is controlled by a controller 11 which receives signals from a photo-interrupter 10 and position detectors 6, 7. To move the typing head 4 back to its initial position, the pulse motor 5 is driven in reverse. When the typing head 4 has reached a position Po, the reverse drive of the motor 5 is continued for a short time and then the motor 5 is driven formward. Thereby, the typing head 4 is stopped into the initial position P1. Therefore, at the time of line changing the typing head 4 can be always returened to the inital position by making the continuation of the reverse drive shorter than the one-pitch motion of the typing head 4.
