- About Sensor
A transmissive type sensor is composed of the light-emitting side and the light-receiving side that
are placed opposite to each other allowing the light to pass from the former to the latter. On the
basis of whether or not the light path is blocked due to the actuator, etc., the sensor detects the
paper absence/presence or the moving part position such as at the home position or elsewhere.
- About Switch
A micro-switch closes the internal contacts via the button which is pushed down under the pro-
vided leaf spring which is held down by the actuator of the cover or door that is being closed.
When the door or cover has being opened, the leaf spring returns to its original position and the
button is pushed up by the spring in the switch, allowing the internal contacts to open.
