Abstract: A sheet processing apparatus capable of shortening time to align sheets. A first alignment member and a second alignment member are movable in a sheet width direction orthogonal to a sheet conveying direction, and align a sheet. A CPU controls the first and second alignment members to be moved in the sheet width direction. A skew sensor detects a skew amount and skew direction of the sheet. The CPU causes the first and second alignment members to be positioned at respective predetermined standby positions before the sheet is received between the first and second alignment member. Further, the CPU causes one of the first and second alignment members to be moved in a direction toward the sheet, based on the detected skew amount and skew direction, during conveyance of the sheet between the first and second alignment members.

Abstract: A transmitter transmits ultrasound to the conveyance path. A receiver receives the ultrasound. A double-feed detector detects whether or not double-feed of a plurality of sheets has occurred. A controller causes the transmitter to transmit ultrasound at a first burst interval when determining the threshold value, and causes the transmitter to transmit ultrasound at a second burst interval, which is shorter than the first burst interval, when detecting the double-feed of sheets. A double-feed detector determines a threshold value that enables distinction between double-feed and single-feed.

Abstract: Provided are a sheet feeding device and an image forming apparatus that are capable of accurately detecting an abnormality of a feeding state without erroneously detecting when a trailing edge of a preceding sheet and a leading edge of a subsequent sheet are fed in an overlaid state. The sheet feeding device includes ultrasonic wave sensors 6 and 7 that detect an overlaid state of a preceding sheet Sa and a subsequent sheet Sb fed from feeding portions 51, 317 to 319 and a controller 1 that continuously performs a detection of the overlaid state of a sheet fed from the feeding portion at a predetermined number of detecting points along a sheet conveying direction at every predetermined time and determines a number of detecting points where detects. Based on the determined number of detecting points, the controller determines that the overlaid state is normal or abnormal.

Abstract: A sheet processing apparatus which is capable of reducing the frequency of switching a convey route. The sheet processing apparatus is provided with a switching unit that switches between a first position at which conveyed sheet is led to a first convey path, and a second position at which conveyed sheet is led to a second convey path. A buffering process of overlaying the conveyed sheet conveyed from a buffer path and another sheet subsequently conveyed by the conveyed unit is performed. The second convey path is used by the buffering process when the conveyed sheet to be received into the buffer path is ejected to the second stacking unit, and the first convey path is used by the buffering process when the conveyed sheet to be received into the buffer path is ejected to the first overlaying unit.
