Screen Feed Mechanism
When the Motor rotates, the Gear of the Screen Main-roller is activated accordingly via the Intermediate Gears.
Two springs on the upper and lower positions adjust the Screen Film tension in the direction of the arrow so as to
bring the Screen Sub-roller into contact with the film.
As shown on the Fig.4.1.1, the Home Marker is attached on the lower position of the scrolled Screen Film so as to tell
Panaboard the screen home position required to feed the screen.
Then the Home Sensor is located on the back of the unit so as to detect the home position.
When the sensor detects the home position, the sensor will inform the control operation block in the CONTROL Board
about the status.
Based on the status, Panaboard will start or stop the screen-feed.
