Abstract: A sheet conveying device, which is included in an image forming apparatus and a post processing device, includes multiple position detectors and a position corrector. The multiple position detectors are aligned along a sheet conveying direction and configured to detect a side end of a sheet. The position corrector is configured to convey the sheet and correct a position of the sheet based on a positional deviation amount of the sheet, obtained by a detection result of the multiple position detectors. The positional deviation amount of the sheet is obtained by an extreme downstream position detector in the sheet conveying direction, of the multiple position detectors. A position of a subsequent sheet is corrected based on a sum of the positional deviation amount of the sheet and a positional deviation amount of the subsequent sheet.

Abstract: A rotator control device includes drivers to drive rotators for sheet conveyance, respectively; and a processor including a selector to select, from the rotators, a pair of a first rotator subjected to rotation speed adjustment and a second rotator adjacent to the first rotator, and an acquisition unit to acquire a torque-related value representing a driving torque value of a driver to drive the second rotator or a value proportional thereto. The processor further includes a speed adjuster to adjust a rotation speed of the first rotator to approximate a variation in the torque-related value to zero. The selector selects a subsequent pair after adjustment of the rotation speed, designates the first rotator of the preceding pair as the second rotator of the subsequent pair, and selects, as the first rotator, a rotator adjacent to the first rotator of the preceding pair, opposite the second rotator of the preceding pair.

Abstract: A sheet conveying device, which is included in an image forming apparatus and a post processing device, includes a position corrector and either one of a rolling body and a contact resistance reducer. The position corrector is configured to convey a sheet and correct a position of the sheet. The rolling body is disposed at least one of an upstream side and a downstream side of a sheet conveyance passage from the position corrector in a sheet conveying direction and is configured to roll in at least a direction intersecting the sheet conveying direction. The contact resistance reducer is configured to reduce contact resistance generated due to contact of the sheet to a neighboring part when the position of the sheet is corrected by the position corrector.

Abstract: A rotating member control device that controls a first rotating member and a second rotating member to convey a sheet includes a processor configured to execute a program to implement processes of controlling the first rotating member and the second rotating member to come into contact or be separated from each other and acquiring a value that corresponds to or is proportional to a driving torque of a first driving unit that rotationally drives the first rotating member. The processor acquires the value upon separation when the first rotating member and the second rotating member are separated from each other and upon conveyance when the sheet is held between and conveyed by the first rotating member and the second rotating member. The processor further sets a rotational speed of the second rotating member such that the value acquired upon separation and the value acquired upon conveyance become equal.

Abstract: A power transmission device includes a drive coupling, a driven coupling, and an intermediate transmission member. The drive coupling receives power from a drive source and rotates. The driven coupling is disposed coaxially on a first rotary shaft of the drive coupling and detachably attachable relative to the main body of the image forming apparatus. The intermediate transmission member meshes with the drive coupling and the driven coupling and is held by one of the drive coupling and the driven coupling in a state in which the driven coupling is disengaged from the main body. One of the drive coupling and the driven coupling, whichever holds the intermediate transmission member, constitutes a retaining coupling including an attachment member attached to one of a drive-side device and a driven-side device, and a stopper assembly facing the intermediate transmission member in an axial direction of the first rotary shaft.

Abstract: A driving device includes a drive source, a planetary gear decelerator, a drive-target shaft, a rotation speed detector, and a sensor mount. The planetary gear decelerator includes a planetary gear mechanism equipped with an output shaft, a sun gear, an outer gear, a plurality of planetary gears, and a rotatable first carrier. The outer gear is made of resin and includes a deformable portion at a drive target side, and the deformable portion is elastically deformable in a radial direction. The plurality of planetary gears engages the sun gear and the outer gear. The rotatable first carrier rotatably supports the planetary gears. The rotation speed detector detects a rotation speed of the planetary gear decelerator, and includes a sensor and a detection target disposed coaxially on the output shaft. The sensor mount supports the sensor and moves in the radial direction in accordance with elastic deformation of the outer gear.
