Abstract
A sheet discharge device carrying to sheet trays recorded sheets sent from an electrostatic copying machine, facsimile and other sheet handling devices. Each sheet discharged from a sheet handling device is pinched by a movable member, carried to one of sheet trays by moving the movable member to the sheet tray, and then discharged thereon. The sheet carry direction is changed by a desirable angle before discharging the sheet on the sheet tray.
Claims11
A sheet discharge device comprising:
- a plurality of sheet trays vertically disposed at predetermined intervals,
- a movable member disposed adjacent to said sheet trays and movable substantially up and down,
- lift drive means for raising and lowering said movable member,
- sheet pinch means disposed on said movable member for momentarily holding sheets discharge to the sheet discharge device,
- sheet discharge means disposed on said movable member for transferring said sheets to the sheet trays,
- drive means for driving one of said sheet pinch means and said sheet discharge means,
- means disposed on said movable member for changing a carrying direction of the sheets transferred by said sheet discharge means, and
- control means including means for controlling said movable member to stand by a home position to receive a sheet and to move to a target position while holding the sheet received using said sheet pinch means, said control means further including means for controlling said sheet discharge means to discharge the sheet onto a target sheet tray, and
- means for returning said movable member to said home position from said target position, said drive means for one of said sheet pinch means and said sheet discharge means being disposed on said movable member, and said lift drive means being disposed outside of said movable member.

A sheet discharge device comprising:
- a plurality of sheet trays vertically disposed at predetermined intervals,
- a movable member disposed adjacent said sheet trays and movable substantially up and down,
- lift drive means for raising and lowering said movable member, sheet pinch means disposed on said movable member for momentarily holding sheets discharged to the sheet discharge device,
