Abstract: According to the present disclosure, a recording medium feeding device includes a pickup roller, a feed roller, a retard roller, a holding member, a pressing mechanism, a pressing force changing mechanism, and a driving force transmitting mechanism. The holding member is configured to rotatably support the feed roller and the pickup roller. The pressing mechanism is configured to press the pickup roller against a recording medium. The pressing force changing mechanism is configured to change the pressing force of the pickup roller. The driving force transmitting mechanism is configured to transmit a rotation-driving force to the feed roller. The pressing force changing mechanism obtains a driving force from the driving force transmitting mechanism, and increases the pressing force according to rotation time of the pickup roller.

Abstract: A sheet feeding device includes a sheet feeding roller, a following roller, a rotational speed detection part, and a control part. The rotational speed detection part is configured to detect a rotational speed of the following roller. The control part is configured to accelerate a rotation of the sheet feeding roller and to adjust a sheet interval. The control part obtains a rotational rate of the following roller to the sheet feeding roller based on the rotational speed of the following roller, obtains an actual linear velocity of the sheet based on the rotational rate of the following roller and a theoretical linear velocity of the sheet after accelerating the rotation of the sheet feeding roller, and then adjusts the sheet interval based on the actual linear velocity of the sheet.

Abstract: A sheet feed conveyance device includes a warning section, a pickup roller that feeds a sheet, a separation section, a speed sensor that detects a conveyance speed of the sheet, and a controller. The separation section includes a feed roller that feeds downstream the sheet fed by the pickup roller and a retard roller that returns a sheet involved in multiple sheet feeding toward the pickup roller. The controller recognizes the conveyance speed based on output of the speed sensor, integrate conveyance speeds detected in a measurement time period from rotation start of the pickup roller to elapse of a specific time period, and determines necessity for maintenance of the pickup roller according to a measurement distance as a result of integration.

Abstract: A sheet feeder includes a tray configured to load a sheet to be fed thereon. The tray has a tray upper face and a pair of cursors. The tray upper face has a recessed portion, a guide plate and a feeding route. The recessed portion extends along the width direction on an upstream side from the pair of cursors in the feeding direction. The guide plate is configured to cover an upper side of the recessed portion. The feeding route is formed between the recessed portion and the guide plate and extending from an inlet port positioned on an upstream side to an outlet port positioned on a downstream side along the feeding direction. The sheet in a state of being passed through the feeding route is aligned with the pair of cursors on the tray upper face and then fed.

Abstract: A sheet conveyance device includes a sheet conveyance passage, a mounting plate, and a sheet detection sensor. The mounting plate is fixed to a recessed portion formed in the inner wall surface of the sheet conveyance passage at its one side it. The sheet detection sensor is fitted on the mounting plate. The sheet detection sensor has a sensor surface. The mounting plate has a mounting surface on which the sheet detection sensor is mounted and a first projection piece which projects from the mounting surface toward the sheet conveyance passage and which is grounded. The first projection piece is disposed upstream, in the sheet conveyance direction, of the sheet detection sensor on the mounting plate. The distance from the mounting surface to the distal end of the first projection piece is greater than the distance from the mounting surface to the sensor surface.

Abstract: A sheet process device includes a supporting member and a process device main body. The supporting member is attached to the lateral face at a side of an in-body sheet ejection space of an image forming apparatus. The process device main body is supported by the supporting member. The process device main body includes a relay conveyance unit and a post process unit. The relay conveyance unit is arranged slidable in a direction to the in-body sheet ejection space. The post process unit is arranged slidable in upward and downward directions with respect to the supporting member. The process device main body provides a sheet conveying path extending from a sheet ejection port of the image forming apparatus to the post process unit through the relay conveyance unit, when the post process unit is moved upwardly after the relay conveyance unit is moved into the in-body sheet ejection space.
