Abstract: A sheet transport device has a housing member, a sheet tray, a transport path, a dispensing portion, a feeding portion, and a projecting member. Sheets are accommodated in the sheet tray. The sheet tray is detachably attached to the housing member, and is configured to be pulled out of the housing member in a first direction. The transport path is disposed in the housing member, and extends from the sheet tray in a second direction perpendicular to the first direction. The dispensing portion dispenses the sheets to the transport path. The feeding portion is rotated in contact with the sheet for feeding the sheet toward downstream of the transport path. The projecting member is configured to be projected and retracted with respect to the transport path near the imaginary line extending from a sheet nip portion in the first direction.

Abstract: A paper feeder includes a lift plate, a pickup roller, a feed roller, a retard roller, a rotation-count detection sensor, and a control unit. The rotation-count detection sensor outputs a rotation-count detection signal. The rotation-count detection signal indicates a rotation count of the retard roller. The control unit detects the rotation count of the retard roller based on the rotation-count detection signal. The lift plate separates from the pickup roller before the control unit detects the rotation count of the retard roller. The feed roller is driven when the control unit detects the rotation count of the retard roller. The retard roller is in abutting contact with the feed roller when the control unit detects the rotation count of the retard roller. The control unit determines whether replacement of the retard roller is necessary or not, based on the detected rotation count of the retard roller.

Abstract: A sheet storage cassette includes a cassette body, a cassette cover, and a lock mechanism. The lock mechanism includes a lock member swingably provided on a back-surface side of the cassette cover and engageable with a locking pin provided in the cassette insertion portion, and a biasing member biasing the lock member in a direction toward engagement with the locking pin. Along with an operation of inserting the cassette body into the cassette insertion portion, the lock member engages with the locking pin. In a state where the cassette body is inserted in the cassette insertion portion, by inserting a thin-plate shaped release member into a gap between the cassette cover and an exterior member arranged under and adjacent to the cassette cover, the lock member is caused to swing to release the engagement with the locking pin.
