摘要： A sheet conveying device, which is included in an image forming apparatus, includes a pair of rollers configured to convey a sheet in a sheet conveyance passage, a detector configured to optically detect an attitude of the sheet, one of a rotation device to rotate the pair of rollers in a direction parallel to a plane of the sheet and a moving device to move the pair of rollers in a width direction, and a controller configured to correct the attitude of the pair of rollers at a time interval, based on a detection result obtained by the detector. The controller performs the correcting operation by setting, according to reflectance of the sheet, at least one of a light emission time of the detector, the time interval of the correcting operation, light emission intensity of the detector and a conveying speed of the sheet.

摘要： A drive control apparatus includes a controller which controls a drive unit based on a voltage instruction signal obtained from a target signal and an abnormality detection unit which obtains the voltage instruction signal M times in a detection time period. The abnormality detection unit detects occurrence of an abnormality in response to detecting that the voltage instruction signal is outside predetermined range N times in the detection time period, where M is equal to or more than 2 and N is equal to or more than 1 and N is less than M.
