    • A copying machine includes an optical sensor of the line scanning type for converting an image into electrical signals, and a thermal recording head controlled in accordance with the image signals. Either the platen or read unit are movable and the read unit will read in both forward and reverse directions of movement, and the magnification value can also be varied. The total width of energized heating elements and the movement length of the read unit or platen may be controlled in accordance with the size of the original. The total number of heating elements energized at any one time is limited, and the machine includes input and output terminals for sending image information externally and for receiving and recording image information other than directly from the read unit. A cutter is provided for cutting the recording paper web immediately prior to discharge.
    • 复印机包括用于将图像转换为电信号的线扫描型光学传感器,以及根据图像信号控制的热敏记录头。 压板或读取单元都可移动,并且读取单元将沿着运动的正向和反向两个方向读取,并且倍率值也可以变化。 通电加热元件的总宽度和读取单元或压板的移动长度可以根据原稿的尺寸来控制。 在任何一个时间通电的加热元件的总数量受到限制,并且该机器包括用于在外部发送图像信息的输入和输出端子,以及用于直接从读取单元接收和记录图像信息。 提供了用于在排出之前立即切割记录纸幅的切割器。

    • A step motor driving circuit having A-phase and B-phase exciting windings which are independently supplied with exciting current in a sequence of four states per step of the step motor. The driving circuit is capable of applying a large or a small current to each phase winding and the currents are applied in a sequence to result in a trapezoidal shaped exciting current. During a first state only one phase is excited and it is excited with the large current. During the second state the one phase is excited with the large current and the other phase with the small current. During the third state both phases are excited with large currents. During the fourth state the one phase is excited with the small current and the other phase with the large current.
    • 具有A相和B相励磁绕组的步进电动机驱动电路,其以阶梯电动机的每步骤四个状态的顺序独立地提供励磁电流。 驱动电路能够对每个相绕组施加大电流或小电流,并且按顺序施加电流以产生梯形激励电流。 在第一状态期间,只有一相被激发,并且其被大电流激发。 在第二状态期间,一相被大电流激励,另一相用小电流激发。 在第三状态期间,两相都被大电流激发。 在第四状态下,一相被小电流激励,另一相以大电流激发。
