Abstract

PURPOSE:To prevent a mechanical shock at the occurrence of abnormality in a motor, by stopping the the movement of the carriage when the signal, which indicates the arrival of the carriage at the left end position of a set manuscript and the like, is not detected. CONSTITUTION:When the carriage 1 arrives at the left end position of the manuscript and the like, all the bindary output from an up down counter 19 become ligic ''0'', and the arrival signal is detected. Then, a timer is incorporated in a control part 21, and the timer is preset at the time when a start/stop control signal S1 of a servomotor is to be generated. The timer is actuated when the time required for the carriage 1 to move from its home stop position to the left end position of the menuscript and the like has elapsed. A gate signal S5 required for generating a preset signal S8 of counter 19 is controlled by the timer. When a read and record effective signal S3 is not outputted, it is judged that the abnormality has occurred in the servomotor control system, the control signal S1 is immediately stopped, and the movement of the carriage 1 is stopped.
