Screen Feed Mechanism
The Screen (Film) supported between the Drive Roller and Sub-drive Roller is fed from right to left (seen from the front) by rotating
the Drive Roller.
As for the rotation of the Drive Roller, rotation of the Screen Motor is transmitted via the Screen Gear.

Paper Feed
After copying operation starts, a little later from the start of screen copy, printing operation starts. First, the Printer Motor is rotated
in the direction of the arrow (1) to connect the Change Gear to the Pick-up Gear Block. Doing so enables the Pick-up Roller to feed
the paper at the Paper Cover to the printing section.

the paper at the Paper Cover to the printing section.
The Cork Rubber is allocated at the opposite side of the Pick-up Roller to separate multiple sheets of paper set at the Paper Cover.
Only one sheet of paper is fed from many sheets of paper that are set, using the principle that the frictional force between the Cork
Rubber and the paper is greater than that between the sheets of paper.

Printing
When the Top Sensor detects the leading edge of the sheet of paper fed by the Pick-up Roller and the leading edge is sent to the
Platen Roller, the rotation direction of the Printer Motor changes to the direction of arrow (2) (reverse rotation).
By this operation, the Change Gear switches to the Transfer Gear Block, and the paper is output to the Output Port while printing
between the Thermal Transfer Film and the Platen Roller.
