摘要： A pulse motor is improved in its stability at the time of low revolution while maintaining the possibility of high revolution. Between the terminals of pulse motor windings there are parallel-connected current control means. The braking effect of said current control means is controlled depending upon the revolution of the pulse motor so as to stabilize the revolution at a low speed. It assures also a high speed revolution when desired. This arrangement of the invention enables to provide a pulse motor which is small in size and low in cost. When the present invention is embodied in a driving system for a carriage of printing head in a printer, all the performances required therefor can be attained.

摘要： A printer provided with a margin setting mechanism is disclosed which has a printing head for writing information on a recording medium, a pulse motor for scan-driving the head, a detector for detecting the position of the head to put out a detection signal, and a control for receiving a phase signal applied to the pulse motor and the detection signal and putting out a signal to reverse the moving direction of the head when receiving both of said phase signal and detection signal.
摘要翻译：公开了一种具有边缘设定机构的打印机，其具有用于在记录介质上写入信息的打印头，用于扫描头部的脉冲电机，用于检测头部的位置以放出检测信号的检测器，以及用于接收施加到脉冲电动机的相位信号和检测信号的控制，并且当接收到所述相位信号和检测信号时，输出信号来反转头部的移动方向。
