Abstract:
An electric stapler in which sheets conveyed along the sheet guide surface are staplied in a stapling position on a sheet guide surface, the electric stapler comprises: a switch; a staple unit for stapling the sheets in the stapling position in response to the switch; a first actuator protruding in part from the sheet guide surface, wherein, when the first actuator brings into contact with more than one place of one edge side of the sheets conveyed beyond the stapling position and moved by the sheets being conveyed, the first actuator actuates the switch so as to operate the stapling unit; and a second actuator positioned upstream the first actuator, a part of the second actuator selectively projecting and retracting with respect to the sheet guide surface, wherein, when the second actuator brings into contact with predetermined lengths of different edge sides constituting a corner portion of the sheets being conveyed beyond the stapling position while the part protruding from the sheet guide surface and moved by the sheets being conveyed, the second actuator actuates the switch so as to operate the stapling unit.
Abstract:
A sheet is conveyed by a conveyor belt which attracts the back side of the sheet under vacuum along a conveyance passage including a bent portion. An air blower is provided to blow an air flow against the upper surface of the conveyor belt at the bent portion of the conveyance passage so that the sheet is bent along the surface of the conveyor belt.
Abstract:
A discharged-sheet table device mounted to an image forming apparatus near the sheet discharging port for receiving a recorded sheet discharged from the sheet discharging port of the image forming apparatus. The discharged-sheet table device includes a first base mounted near the sheet discharging port of the image forming apparatus; a second base movably supported on the first base; a discharged-sheet table movably mounted on the second base to receive the recorded sheet which is discharged from the image forming apparatus; a table moving mechanism for movably holding the discharged-sheet table between a first position where the recorded sheet discharged from the sheet discharging port is received and a second position located forwardly of the first position in the direction in which the recorded sheet is discharged from the sheet discharging port; and a first base moving mechanism disposed between the first base and the second base, for movably holding the second base between the second position and a third position offset in a direction horizontally from the direction in which the recorded sheet is discharged from the sheet discharging port. To remove a stack of papers from the discharged-sheet table, an operator moves the discharged-sheet table from the first position to the second position forward of the first position and away from the discharging port, and then to moves the discharged-sheet table from the second position the third position which is laterally offset from the first and second positions.
