摘要： In some examples, a sheet processing machine includes at least one infeed system including at least one transport means including at least one upper holder and at least one lower holder. The at least one transport means can be and/or is arranged in at least three states: a maximally closed state corresponding to a minimal distance, a minimally closed state corresponding to a maximal distance, and an at least one mean state corresponding to at least one mean distance between at least one upper holding surface at least of the respective upper holder, and at least one lower holding surface of the lower holder of the at least one transport means that is assigned to the respective upper holder. During a machine cycle, the at least one transport means has each of the minimally closed state, the maximally closed state, and the at least one mean state at least once.

摘要： A sheet feeding device includes a feeding roller pair, a detecting portion, a first changing portion, a second changing portion, and a controller for controlling the first changing portion and the second changing portion. The controller starts a first feeding operation for feeding a sheet toward the obliquely feeding roller pair in a nipping state of the feeding roller pair and then starts a second feeding operation for feeding the sheet for abutting a side end of the sheet against the reference member in the nipping state of the obliquely feeding roller pair. The controller changes, after the first feeding operation is started and before the second feeding operation is started, a start timing of the second feeding operation on the basis of a detection result of a position of the side end of the sheet detected by the detecting portion.

摘要： A sensing apparatus can be configured to detect an edge of a paper that is received by an automated transaction machine (ATM). The paper can move along a path located inside the ATM, the path having opposite first and second sides. The sensing apparatus can include a light emitter and a light detector on the first side of the path, with the light emitter positioned so that it can emit light across the path to the second side. The light detector can be configured to detect light from the light emitter and can emit a signal corresponding to an amount of detected light. The sensing apparatus can also include a control circuit that can control a flow of power to the light emitter, and the control circuit can also receive the signal emitted by the sensor.

摘要： The image forming apparatus includes a transfer section that transfers an image to a sheet; a sheet conveying member that is provided on an upstream side of the transfer section in a conveying direction of the sheet and that conveys the sheet; and a hardware processor that controls displacement of the sheet conveying member such that the sheet is displaced in a width direction of the sheet. The hardware processor causes a detector that detects an edge of the sheet in the width direction to detect the edge of the sheet after displacement of the sheet conveying member has been started, and causes the displacement to be terminated on the basis of the detected result such that the edge of the sheet reaches a target position.

摘要： A sheet conveying device, which is incorporated in an image forming apparatus, includes a first detector to detect an angle deviation of a recording medium to a sheet conveying direction, a second detector to detect a lateral shift of the recording medium to a width direction, a third detector to detect at least one of the angle deviation and the lateral shift after correction of the angle deviation detected by the first detector and the lateral shift detected by the second detector, and a rotary body to perform a primary movement by (1) rotating in the sheet conveying direction and returning to a reference position and by (2) moving in the width direction and returning to the reference position, and a secondary movement by performing at least one of (1) and (2) after the primary movement.

摘要： A sheet conveying device includes a correcting unit. The correcting unit corrects displacement of a sheet conveyed from an upstream side conveying path, and conveys the sheet to a downstream side conveying path. The correcting unit includes a first conveying part conveying the sheet, a first moving part moving a first frame supporting the first conveying part and a detecting part detecting a side end edge of the sheet at a reference position without displacement. The first conveying part stops conveyance of the sheet when a leading end of the sheet reaches the detecting part. While the driving of the first conveying part is stopped, the first moving part moves the first frame to move the sheet, and stops movement of the first frame, when detection result of the detecting part is changed, to position the side end edge to the reference position to correct displacement of the sheet.

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.
