    • A photoreceptor belt control apparatus for a printer having a photoreceptor belt that circulates around rollers rotatably installed on a belt frame. The apparatus includes a pair of auxiliary frames slidably and pivotally installed on the belt frame, and a steering roller whose ends are rotatably installed respectively on the auxiliary frames. The steering roller rotates in contact with the photoreceptor belt. A shaft is rotatably installed on the belt frame, and a cam unit is installed on at least one end of the shaft for controlling the inclination of the steering roller by pivoting each of the auxiliary frames according to the rotational position of the shaft. A tension control unit controls the tension in the photoreceptor belt by sliding the pair of auxiliary frames.
    • 一种用于打印机的感光带控制装置,其具有围绕可旋转地安装在带框架上的辊周围的感光带。 该装置包括一对可滑动地且可枢转地安装在带框架上的辅助框架,以及转向辊,其端部分别可旋转地安装在辅助框架上。 转向辊与感光带接触转动。 轴可旋转地安装在带框架上,并且凸轮单元安装在轴的至少一端,用于通过根据轴的旋转位置枢转每个辅助框架来控制转向辊的倾斜。 张力控制单元通过滑动一对辅助框架来控制感光带中的张力。
