摘要： A sheet feeder apparatus is provided. The apparatus comprises a width detector for a sheet placed on a sheet placement portion, a conveyor for conveying sheets while separating the sheets one by one, a first detector for a sheet having a first width at a plurality of first positions, a second detector for a sheet having a second width that is not detected by the first sheet detector, at a plurality of second positions, and a controller for determining skewing of a sheet based on a result of the detection of the sheet performed by the first detector if the width of the sheet is the first width, and determining skewing of a sheet based on a result of the detection performed by the second detector if the width of the sheet is the second width.

摘要： A sheet feeding device includes a sheet feeding body, a sheet separating body, a loading body, a support, and a pressing body. The sheet feeding body is configured to feed a recording sheet. The sheet separating body is configured to separate the recording medium and convey the recording medium together with the sheet feeding body. The loading body is configured to load the recording medium to be fed by the sheet feeding body. The support is disposed above the sheet separating body. The pressing body is made of metal and rotatably supported by the support between the loading body and the sheet separating body. The pressing body includes a part-shaped face to contact or face the recording medium. A surface of the part is covered with a metal plating.

摘要： A clutch device includes a sector gear, a cam, an electromagnetic solenoid, a first lever, a second lever, a first spring, and a second spring. The cam includes a slide portion. The first lever engages with the electromagnetic solenoid and includes a first restricting portion. The second lever includes a hook and a second restricting portion. The first spring is configured to urge the second lever in a direction in which the first restricting portion and the second restricting portion contact each other. The second spring is configured to, when the electromagnetic solenoid is in a de-energized state, move the first lever. The slide portion of the cam has a surface configured to, when the electromagnetic solenoid is in an energized state, press the hook in a direction opposite to an urging direction of the first spring such that the second restricting portion is separated from the first restricting portion.

摘要： A sheet feeding device includes a contact member and a lock member. The contact member is configured to rotate from a retracted position to a contact position while a sliding portion of the lock member is sliding on a sliding target portion of the contact member and to rotate to the contact position to release the sliding portion of the lock member from the sliding target portion of the contact member. The lock member is configured to rotate between a locked position and a lock released position by a lock biasing force when the lock member moves in a lock direction of the lock member from the lock released position toward the locked position. The contact member has the lock target body and the sliding target portion at different positions from each other in a rotation center axial direction of the contact member.

摘要： A paper pickup mechanism includes a mechanical frame, a pickup roller module, a feeding roller module, a driving device, a separation roller module and an energy storage element. The mechanical frame has a platform. The pickup roller module is pivoted to and connected to the mechanical frame. The feeding roller module is pivoted to and connected to the mechanical frame. The driving device is mounted to the mechanical frame. The separation roller module is pivoted to and connected to the mechanical frame. The energy storage element is mounted between the mechanical frame and the separation roller module. When the separation roller module rotates together with the feeding roller module in a forward direction, the energy storage element accumulates energies. When more than one piece of paper is fed into the paper pickup mechanism, the energy storage element releases the energies.

摘要： A manual feed tray includes a tray body and a lift unit, and the lift unit includes a lift plate, a lift spring and a pair of cursors. The cursor includes a guide portion. When the manual feed tray is closed from a sheet feeding state of the lift plate, the guide portion comes into contact with a facing wall portion, whereby a downstream side of the lift plate in a covering direction moves downward. Thus, even if the manual feed tray is closed with the lift plate moved upward, the lift plate smoothly moves downward.

摘要： A contact-separation mechanism includes a cam to rotate to move a contact-separation member to and from a counterpart member, a detection target to rotate together with the cam, and a detector to detect presence or absence of the detection target in a detection area of the detector, and circuitry. The cam has a reference range. The circuitry issues a rotation stop instruction of the cam after a target time elapses from passing of the reference range of the detection target through the detection area, and sets the target time based on a duration of an immediately preceding passing of the reference range through the detection area.

摘要： A sheet conveying device includes a supporting shaft, a rotating unit removable from an installation portion, a movable shaft, and an interlocking device. The rotating unit includes first and second ends, a holding member that holds a rotating body that conveys a sheet. The supporting shaft supports the rotating unit at the first end in an axial direction of the rotating body. The movable shaft is movable in the axial direction and supports the second end. The interlocking device moves the movable shaft per the rotating unit movement. Where the rotating unit is to be moved at a moving amount towards a side in which the rotating unit separates from the supporting shaft as part of removing the rotating unit from the installation portion, the interlocking device moves the movable shaft in the axial direction at a moving amount that is larger than the moving amount the rotating unit.
