摘要： An image reading device including a contact glass; a reading unit; a pressure plate; a pressure-plate opening/closing sensor; and circuitry. The circuitry determines a presence or absence of external light input to a space between the pressure plate and the surface of the contact glass based on image data obtained by the reading unit when the light source is turned off; compares read data according to light emitted from the light source and received by the image sensor when the pressure plate is closed, with read data of a reference value obtained when the pressure plate is completely closed, to obtain a difference and determine a state of the read data based on the difference; and determines whether the pressure plate is open or closed based on a determination result of the presence or absence of external light and on the difference.

摘要： An image-reading unit includes an original document conveyor that includes a first original document tray to hold an original document to be read, a first original document feeding port to feed the original document placed on the first original document tray, and an original document conveying path to convey the original document from the first original document feeding port to an original document discharging port. The original document conveyor further includes an openable second original document tray attached near an intermediate portion of the original document conveying path to hold an original document when opened, and a second original document feeding port to feed the original document on the second original document tray. The image-reading unit further includes an image reader to read an image of the original document being conveyed along the original document conveying path.

摘要： An image reading device includes: a reading unit; a first detecting unit that detects a position of the reading unit in the sub-scanning direction; a second detecting unit that detects a position of the reading unit in the sub-scanning direction; and a calculating unit that calculates a skew quantity and a skew direction of the reading unit, based on a difference, introduced by the skew, between a travel distance by which the reading unit has travelled from a measurement reference position located on an upstream side of the first detecting unit and the second detecting unit in a moving direction to a point where the reading unit is detected by the first detecting unit, and a travel distance by which the reading unit has travelled from the measurement reference position to a point where the reading unit is detected by the second detecting unit.

摘要： An automatic document feeder that is included in an image reader of an image forming apparatus includes a sheet conveying roller, a document feeder cover, a projection piece, a motor, a driving side gear, and a driving force transmission device including an idler gear, a driving force release gear, a slide body, a first elastic body to bias the idler gear and the driving force release gear to be separated, a second elastic body to bias the driving force release gear and the slide body to be separated, and a drive shaft. The driving force transmission device meshes the driving and driven side meshing portions together with a biasing force applied by the second elastic body when the document feeder cover is closed, and releases the driving and driven side meshing portions with a biasing force applied by the first elastic body when the document feeder cover is opened.
