Patent ID: 8561984

Claim:
A sheet take-out apparatus comprising: a take-out structure, so as to control gaps between sheets taken-out on a conveying path to a target value, configured to continuously take out a plurality of sheets from a take-out position; a separation structure configured to separate the overlapped sheets taken-out by the take-out structure and convey the separated sheet to the conveying path; a gap detection portion configured to detect the gaps between the sheets taken out by the take-out structure and conveyed via the conveying path; a control portion configured to control the take-out operation of a first sheet by the take-out structure, based on a first gap between the first sheet detected by the gap detection portion and under take-out by the take-out structure and a second sheet taken out and conveyed precedingly on the conveying path, and a second gap between a third sheet taken out and conveyed further precedingly on the conveying path and the second sheet, the control portion adjusting take-out timing of the first sheet by the take-out structure in order to make the total value of the first and second gaps at least larger than a doubled value of the target value; and a correction portion, provided downstream from the conveying path, configured to adjust a conveying speed of the second sheet so that the first gap and the second gap become the target value based on only the first gap and the second gap detected by the gap detection portion.
