Chapter 2 Operation
2.2.2 Spacing operation
Spacing is effected by driving the carriage assembly installed to the main shaft and slide beam set in parallel with the
platen by the DC servo motor.
(a) DC motor with motor
(b) Carriage frame
(c) Carriage shaft
(d) Space belt
(e) Sensor
(f) Encoder disk
(1) Spacing operation
The carriage mounting the printhead moves in parallel with the platen along the main shaft and slide beam. The carriage
is fixed to the mini pitch belt under the carriage frame.
When the DC servo motor runs clockwise as viewed from its front side, the driving force is transmitted to the mini pitch
belt and the carriage moves from the left to the right. The DC servo motor rotating angle and speed are controlled by the
count of øA and øB signals (with a phase difference of about 90°) from the encoder and the time intervals of the signals.
The rotating direction is determined by the sign (positive or negative) of the phase difference between øA and øB.
The mechanism is designed so that the carriage moves 2.22 inches (56.44 mm) when the DC servo motor makes one
revolution.
