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.
