Stopper device for a sheet feeder

摘要

The stopper (112) has an arm (114) pivoted around an axle (113) that is parallel to axles (102, 108) of paper driving rollers. An end (116) contacts with a base of a trough (117) and a wall (115) constitutes an obstacle to the insertion of paper sheet in the trough, when stopper is in down position. The arm contacts a spigot (118) of a support (103) of a loader, where the spigot activates the stopper between up and down position.
