2-1-1 Mechanical construction
The side deck (SD) is comprised of the paper elevating mechanism; which is activated by winding up of the lift
wire using the SD lift motor (SDLM), SD forwarding roller, SD feed roller, paper feeder which is driven by the
SD separation roller, and the paper relaying unit which is driven the SD feed roller.
The elevator plate is elevated when the wire hooked with a pulley, which is driven by the SD lift motor (SDLM),
is wound up. The top and bottom dead ends are detected by the SD top limit sensor (SDULS) and SD bottom
sensor (SDLLS) to stop the elevator plate.
The feed system is a mechanism that feeds paper into the main device using the SD feed roller after
separating paper by the SD forward roller, SD feed roller and the SD separation roller one by one using feed-
and-reverse rollers method.
