  • Publication number: 20210317639
    Abstract: A data collection device is mounted on a work machine and collects data that is collectable from the work machine. The data collection device includes a collectable list generation unit and a collectable list notification unit. The collectable list generation unit updates a collectable list indicating a type of data that is collectable from the work machine, in a case in which a change has occurred in the type of data that is collectable. The collectable list notification unit transmits the updated collectable list to an external device outside the work machine.

  • Patent number: 10875728
    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.

  • Patent number: 10730713
    Abstract: 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.

  • Patent number: 10584008
    Abstract: 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.

  • Patent number: 10530950
    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.
