マルプリンタの駆動機構。Between the platen and the guide surface arranged at regular intervals,
A movable carriage is provided, and the part of the carriage facing the platen is equipped with a thermal head, and the part facing the guide surface of the carriage has one side with a small width and the other side with a wide width along the movement direction. A notch is formed in the notch, and a wire is pulled in the notch, and when the wire is pulled in one direction, the wire intervenes between the narrow width part and the guide surface, and presses the thermal head against the platen. A drive element is provided to provide a moving force in the writing direction, and a roller is provided in front of the platen for feeding out the thermal paper.
A one-way clutch is interposed between a group of gears connecting the pulley to which the wire is hung, and which transmits power when the driver is pulled in a direction opposite to the writing direction. Drive mechanism.
