Abstract: An image reading apparatus for separating and conveying documents from a bundle of documents, causing the document to pass through a reading position, and reading an image from the document, includes: a reading translucent plate; a rotation member capable of rotating around a shaft; and a rotation driver that rotates the rotation member, wherein in the rotation member, each of: a cleaning member; a white reference area; and an end portion detection area is formed partially with regard to a circumferential direction, the cleaning member and the end portion detection area are arranged adjacent to each other, the rotation driver is arranged so that the end portion detection area faces an opposing surface, and the rotation member is rotated in a paper interval period from when a trailing edge of the document passes the reading position to when a leading edge of a subsequent document reaches the reading position,

Abstract: A sheet conveying apparatus has a reference roller, a detection roller, and a detection sensor. The detection roller can move, and makes contact with the reference roller, facing the reference roller. The detection sensor outputs a signal corresponding to the displacement of the detection roller. The sheet is conveyed to a nip portion of the pair of rollers. At this time, the timing when an edge portion of the sheet being conveyed passes through the nip portion is detected. In response to the timing detected, the thickness of the sheet is detected, based on the signal output from the detection sensor.

Abstract: An image forming system conveys a recording medium to form an image. The image forming system includes: a driver to drive an operation mechanism to convey a recording medium or an operation mechanism to form an image on the recording medium; a detector that detects a driving state of the driver; a diagnostic section diagnosing an abnormality of the operation mechanism based on a load obtained by converting a detection result by the detector based on a predetermined conversion condition; and an updater that, when at least one of components of the driver is replaced, updates the conversion condition in accordance with the replaced component.

Abstract: An image forming apparatus as a sheet conveying apparatus comprises a paper feeding roller, an upstream side sensor, and an ultrasonic wave sensor. The paper feeding roller provides a plurality of sheets placed on a document tray in series to a conveying path. The upstream side sensor detects presence or absence of a sheet being conveyed along the conveying path, at a location of a downstream side of the paper feeding roller along the conveying path. The ultrasonic wave sensor detects presence or absence of occurrence of multiple feed, based on intensity of ultrasonic waves received at a location of a downstream side of the upstream side sensor along the conveying path.
