Claims

[Scope of utility model registration request]

an automatic duplexing unit that temporarily accumulates sheets with one-sided copies copied; a guide selector that selects the paper conveyance direction for single-sided copying and duplex copying; a feed roller that feeds the single-sided copying paper to the automatic duplexing unit; a movable push plate that pushes the leading edge of the paper fed into the unit to position it below the feed roller;
Forming a part of the automatic duplexing unit, the push-up plate is capable of moving the temporarily stacked paper toward and away from the feed roller, and the push-up plate is constantly pressed against the feed roller by the tension of a spring to make single-sided copies. An automatic double-sided copying device characterized in that when finished sheets are temporarily accumulated, they are pushed down by an eccentric cam.
