Abstract: An image reading apparatus comprises a reading unit including a movable sensor, a first reading mechanism which moves the reading unit to read an original placed on a platen, a second reading mechanism which conveys the original relative to the reading unit to read the original, a common driving source which drives the first reading mechanism and the second reading mechanism, a transfer unit which transfers a driving force from the driving source to the first reading mechanism and the second reading mechanism, and a switching unit which switches rotation used to drive the second reading mechanism to one of forward rotation and reverse rotation with respect to rotation of the driving source in one direction, the switching unit operating as the reading unit moves.

Abstract: The present invention provides a sheet conveying device comprising a first conveyance path for conveying a sheet from a pair of first rollers to a pair of second rollers, a second conveyance path for performing switchback conveyance of the sheet, a switching unit for switching the second rollers between a press-contacted state and a separated state, and a single driving source for driving the rollers and the switching unit. A non transferring of drive section is set where when the driving source switches the rotation direction after the sheet that has been switchback-conveyed has reached the first rollers, a drive from the driving source is not transferred to the second rollers. The switching unit is driven to separate the second rollers during a time the drive is not transferred to the second rollers due to the non transferring of drive section.

Abstract: An image reading apparatus comprises a feeding mechanism conveying a document, a moving mechanism moving a reading unit, a driving source shared by the mechanisms, a biasing mechanism moving the reading unit to a predetermined position by an elastic member when the reading unit is moved out of a reading region, a transmission element being displaced by the movement of the reading unit and switching transmission of the drive force, and a disengaging mechanism disengaging the reading unit in the predetermined position to the reading region from the predetermined position by the drive force of the driving source.

Abstract: A recording medium supply device includes a cassette attachable to and detachable from a main body and capable of stacking recording medium thereon, a feeding roller which feeds the uppermost recording medium to the main body from a leading end of the recording medium, a regulating member which is arranged forward in the direction in which the cassette is removed from the main body as seen from the feeding roller, and a projection preventing member attached adjacent to the tip portion of the cassette facing the leading end of the recording medium.
