A laser processing apparatus includes: a conveyor to convey a container containing a content in a container body in a conveying direction at a predetermined conveying speed; and a light emitter to emit laser light to a predetermined processing region in the container body conveyed in the conveying direction by the conveyor. A frequency of a vibration of the container body conveyed, in which an amplitude of the vibration of the container body is maximized, is v/L or less, where v is the predetermined conveying speed, and L is a length of the predetermined processing region in the conveying direction.

Container body, laser processing apparatus, and laser processing method

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.

Sheet conveying device and image forming apparatus incorporating the sheet conveying device

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.

A sheet conveying device, which is included in an image forming apparatus, includes a sheet holding roller to move while holding a sheet, a detector to perform a primary detection to detect a sheet position before the sheet holding roller holds the sheet and a secondary detection to detect a sheet position downstream from the sheet position detected by the primary detection, and a controller configured to cause the sheet holding roller to perform a first drive to move the sheet holding roller in at least one direction of a width direction of the sheet and a rotation direction in a sheet conveying surface based on a result of the primary detection and a second drive to move the sheet holding roller opposite to the at least one direction of the first drive, based on a result of the secondary detection.

A sheet conveying device, which is included in an image forming apparatus, includes a detector to detect a lateral end face of a sheet, a first pair of rollers to hold and convey the sheet and swing in a direction parallel to a plane of the sheet, a second pair of rollers to convey the sheet together with the first pair of rollers, and a controller to rotate the first pair of rollers to multiple angles, detect time changes at each angle at the lateral end face while conveying the sheet, and determine a home position corresponding to a position where respective rates of the time changes of the sheet at the first and second nip regions are substantially identical to each other or a home position having a least difference of rates of the time changes of the sheet at the first and second nip regions.

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.

Rotating member control device, conveying device, and image forming apparatus

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.

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.

A planetary gear mechanism includes a plurality of planetary gears, an outer gear, a sun gear, a carrier, and a stick mount. The outer gear meshes with the plurality of planetary gears. The sun gear is coaxially disposed on the same axis as the outer gear and transmits force to the planetary gears. The carrier rotatably supports the plurality of planetary gears and is rotatably and floatingly supported. The carrier includes a hole through which a stick member penetrates in a direction of axis of rotation of the carrier. The stick member penetrates through the hole and is mounted on the stick mount. The stick mount is disposed opposite the carrier. The outer gear and the sun gear are held such that one of the outer gear and the sun gear does not rotate.

Planetary gear assembly, drive unit including the planetary gear assembly, and image forming apparatus including the drive unit, and installation method for planetary gear assembly

An image reading device, which is included in an image forming apparatus and used to perform a method of reading images, includes an image reading body configured to read one of a recording medium and the recording medium together with a background area adjacent to the recording medium, a moving body disposed facing the image reading body, and a reference body as a reference in shading correction. The moving body is configured to hold the recording medium and the reference body in a direction intersecting a sheet conveying direction of the recording medium such that the recording medium and the reference body contact to and separate from the image reading body.
