2.5.1 Carriage Movement Mechanism
Carriage movement mechanism consists of a carriage unit, CR motor, timing belt,
carriage guide shaft, CR scale, and CR encoder.
Rotational drive of the CR motor is transmitted to the carriage unit through the timing
belt, and the carriage unit moves left and right along the carriage guide shaft. The CR
encoder installed on the back of the carriage unit reads the jagged surface of the CR
scale and sends the read value to the main board. Position and moving speed of the
carriage unit are controlled based on the read value.
