PURPOSE:To make possible the limitation of the required number of drive sources to only one and ensure that the subject device is simple and works accurately by permitting a single displacement value conversion device to occupy from the first to the fourth position and also the device to be mechanically interlocked to this action for the movement of a recording head and a pinch roller and the control of a paper feed device. CONSTITUTION:If a sensor detects the tip of recording paper, a motor drives a cam and allows it to rotate until the cam reaches the second position where point B agrees with point O. After the completion of paper feed synchronized with the rotation of the motor, the cam is allowed to rotate until it reaches the first position where point A coincides with point O. The motion of a thermal head contacting a platen under pressure is synchronized with the rotation of the cam. After the completion of the first color recording, the cam is allowed to rotate to the second position. A switching pawl for recording paper transport path is positioned so that the paper is guided to a discharge path. Therefore, after the discharge of the paper, the cam is permitted to rotate until it reaches the fourth position where point D meets point O. The linking joint 104a is displaced to a position where the thermal head is parked further from the platen to complete a recording sequence. |
