Home-position detector mechanism

This mechanism is installed at the right end of the head carriage assembly stroke range. The

mechanism detects the carriage assembly’s position as well as errors in the carriage operation.

The detector detects the detection plate located on the rear of the carriage assembly as default.

The detector consists of an LED and a photo IC. When the carriage assembly moves, the detector

plate pass through between the LED and the photo IC. Since the optical axis is blocked at this

time, the level of the IC output will be changed. The change in IC output serves as the detection

signal of the moving position of the carriage assembly.

Carriage detector mechanism

This mechanisms uses a rotary encoder mounted directly on the rotating shaft of the carriage

motor ("Motor, carriage") to detect errors in motor rotation. The mechanism consists of a

detector plate ("Detector plate, carriage") and a carriage detector.
