  • Patent number: 8657286
    Abstract: A sheet stacking apparatus which is capable of efficiently stacking sheets of various sizes while efficiently using space therein to thereby realize compactness thereof, and maintaining a high availability. Stacker trays for stacking sheets discharged from an image forming apparatus can be separately removed. It is detected whether any of the stacker trays is removed. When large-size sheets are stacked, a stacker control section causes the stacker trays to operate as one tray to stack the sheets in a state extending on the stacker trays, whereas when small-size sheets are stacked, the section causes one of the stacker trays to stack the sheets. Further, when one stacker tray is removed to make it impossible to stack the large-size sheets, the section causes a display section to display a guide message advising setting of the removed stacker tray.

  • Patent number: 8554128
    Abstract: A sheet processing apparatus which is capable of improving operability while suppressing an increase in apparatus size. In a front cover insertion mode, an insertion sheet for a front cover is inserted into a bundle of sheets on which images have been formed, and in a rear cover insertion mode, an insertion sheet for a rear cover is inserted into the bundle of sheets. Insertion sheets for the front cover and insertion sheets for the rear cover are set with the same orientation in a manual feed tray 105. An insertion sheet for the front cover stored in the manual feed tray 105 is conveyed to a finisher 500 in one of a face-down state and a face-up state. An insertion sheet for the rear cover stored in the manual feed tray 105 is conveyed to the finisher 500 in the other of the face-down state and the face-up state. The insertion sheets for the front cover and for the rear cover conveyed from the manual feed tray 105 and the sheets on which images have been formed are stacked on the finisher 500.

  • Patent number: 8083220
    Abstract: A sheet processing apparatus capable of reliably superposing a sheet to be buffered and a following sheet in a manner displaced by an allowable displacement amount, thereby making it possible to suppress generation of misalignment. A sheet discharged from an image forming apparatus is temporarily held back, and a following sheet is superposed on the held-back sheet in a state displaced in a conveying direction. A length in the conveying direction of the sheet to be held back and a length in the conveying direction of a sheet bundle of the superposed sheets are measured. A displacement amount provided between the superposed sheets, computed as a difference between the measured length of the sheet and the measured length of the sheet bundle, is adjusted such that the displacement amount becomes a target displacement amount.

  • Patent number: 8066279
    Abstract: A sheet conveyance apparatus capable of detecting a sheet end portion in a short time period even if sheets are conveyed at a narrow interval and at high speed, thus making it possible to expedite the start timing of a subsequent sheet alignment operation. In accordance with results of detection by lateral registration detection sensors performed when a sheet reaches a lateral registration detection sensor unit, the sensor unit is moved in a width direction for sheet end detection. Based on a moving distance of the sensor unit from a standby position to a position where the sheet end is detected, a shift amount to be shifted the sheet in the width direction, i.e., a lateral registration error, is computed.

  • Patent number: 7766315
    Abstract: A sheet stacking apparatus which is capable of efficiently stacking sheets of various sizes while making efficient use of space therein to realizing compactness of the apparatus. Stacker trays that are driven by respective tray lift motors perform a lifting/lowering operation to have sheets stacked thereon. Selection is made according to the size of sheets between a first stacking mode for stacking sheets having a size not larger than a predetermined size on one of the stacker trays and a second stacking mode for stacking sheets having a size larger than the predetermined size in a state extending on the stacker trays. When it is determined that one of the stacker trays is faulty, execution of the second stacking mode is inhibited, and execution of the first stacking mode using the other stacker tray is permitted.
