Abstract

When sheet paper is to be stacked in an exit tray, such as at the output of a copying machine, sheet jams are less likely to occur if the leading edge of all size sheets are registered against the tray's stationary wall, without rebounding therefrom.

Variable Size Exit Tray

When sheet paper is to be stacked in an exit tray, such as at the output of a copying machine, sheet jams are less likely to occur if the leading edge of all size sheets are registered against the tray's stationary wall, without rebounding therefrom.

Exit tray 10 includes a stationary wall 11 against which the sheet's leading edges are to be stacked. The tray's floor 12 is pivoted at 13 and is spring biased counterclockwise by a spring which is not shown. All size paper sheets which are to be stacked in the tray are driven into the tray by rollers 14 and 15.

If wide sheets are being fed, i.e., wide in the direction of sheet travel, movable deflector 16 is positioned in its dotted-line position 17. As a result, wide paper follows path 18. As it passes along this path, the sheet encounters roller
19. This roller is gravity biased onto floor 12, and is rotationally supported on wire guide 20, this guide being pivoted at 21. Roller 19 may be free to rotate in only the clockwise direction. Roller 19 operates to decelerate the sheet, and when the sheet's leading edge hits wall 11, the roller prevents rebound therefrom.

If narrow sheets are being fed, movable deflector 16 is positioned in its solid- line position, as shown. Narrow paper is now directed along path 22. As a result, the narrow sheets are subjected to an additional driving force at drive rollers 23 and 24. As narrow sheets leave the nip of rollers 23 and 24 they are guided under roll...
