    摘要: A CMOS sensor scans an image that is either on a transfer material carrier or on a transfer material that is placed on the transfer material carrier. A sampling timing controller samples an image signal at a predetermined sampling rate and computes a position of a predetermined pattern contained within the sampled image signal. A speed computation processor computes a moving speed of either the transfer material carrier or the transfer material, based on the position of the predetermined pattern thus sampled at the predetermined sampling rate and computed, as well as the predetermined sampling rate. The image region that the CMOS sensor scans is determined in accordance with the rotational speed of the drive motor and the sampling rate.

    摘要: A sheet conveying device for conveying a sheet includes a displacement-amount detector configured to detect an amount of displacement of a conveyed sheet from a conveyance reference in a width direction being substantially perpendicular to a sheet conveying direction and a plurality of sheet conveying roller portions configured to be shiftable in a direction substantially perpendicular to the sheet conveying direction while pinching the sheet having the amount of displacement detected by the displacement-amount detector. Before the sheet reaches the sheet conveying roller portions, the sheet conveying roller portions are shifted based on the amount of displacement detected by the displacement-amount detector from a conveyance-reference position in a direction in which the sheet is displaced. After the sheet reaches the sheet conveying roller portions, the sheet conveying roller portions are shifted while pinching the sheet so as to reduce the amount of displacement.

    摘要: When an abnormality factor occurs in a second heating device, a sheet located upstream of a branch portion is discharged onto a discharge tray through a second conveying path. After the abnormality factor in the second heating device is removed and the sheet discharged to the discharge tray through the second conveying path is set in a paper refeeding tray, a sheet feeding portion feeds the sheet set in the paper refeeding tray to the second heating device.

    摘要: The present invention provides a sheet conveying apparatus and an image forming apparatus capable of preventing occurrence of skew feeding when correcting sheet lateral deviation. A pair of lateral-shift correcting rollers 305 to correct positional deviation in the sheet width direction based on positional deviation quantity detected by a lateral-registration detection sensor 204c is controlled after controlling a skew feeding correcting roller 203 so as to correct sheet skew feeding based on skew-feeding quantity at a sheet leading edge detected by skew-feeding detection sensors 204a and 204b. Then, skew-feeding quantity of the sheet leading edge to be detected by the skew-feeding detection sensors 204a and 204b for correcting skew feeding of the next sheet is adjusted with skew-feeding quantity at the sheet trailing edge detected by the lateral-registration detection sensor 204c after positional deviation in the sheet width direction is corrected.
