An attachment is attachable to and detachable from a sheet stacking board. The attachment includes an end fence configured to restrict a position of a trailing end of a sheet in a conveying direction. The end fence includes a facing surface facing the trailing end of the sheet. The facing surface includes an inclined surface inclined with respect to a vertical direction of a stacking surface on which the sheet is stacked, such that a higher part of the facing surface is located more upstream in the sheet conveying direction.

A sheet conveyor, which is incorporated in an image forming apparatus and in which a method of preventing sheet skew is performed, includes a sheet conveying path through which a sheet is conveyed, a first conveying unit disposed in a sheet conveying direction and including a shaft extending in a lateral direction, multiple rollers attached to the shaft along the shaft, and a rotation regulator disposed between each of the multiple rollers and the shaft to idly rotate each of the multiple rollers in a given range about the shaft, a second conveying unit disposed along the sheet conveying path and downstream from the first conveying unit in the sheet conveying direction, and a sheet abutting part provided at the second conveying unit, against which a leading edge of the sheet abuts to form a slack of the sheet to correct skew of the sheet.
摘要:
A paper feed device including a paper feed unit configured to feed sheets; a separation unit configured to separate and feed the sheets fed from the paper feed unit automatically one by one; a sheet guide member provided between the paper feed unit and the separation unit, the sheet guide member provided on a downstream side relative to a sheet feed direction rotatably supported at one edge thereof; and a guide driving member configured to change a sheet guide position of the sheet guide member depending on a sheet type.

A mobile image forming apparatus includes a body, a recording device supported by the body and configured to form an image on a recording medium, a roller provided to the body and configured to rotate on the recording medium while the body is moved in a scanning direction for image formation. The mobile image forming apparatus further includes a switching device configured to switch a state of the mobile image forming apparatus during image formation between a roller contact state in which the roller is in contact with the recording medium and a roller contactless state in which the roller is contactless with the recording medium.

A sheet conveying device includes a first rotating member, a second rotating member, and a biasing unit that biases the second rotating member toward the first rotating member. The first and second rotating members pinch a sheet therebetween and convey the sheet in a sheet conveying direction. The second rotating member includes a small-diameter portion that faces a conveying portion of the first rotating member, and a large-diameter portion at a position axially displaced from the conveying portion. The second rotating member can change its orientation to an orientation where a rotating shaft of the second rotating member is tilted relative to a rotating shaft of the first rotating member as viewed in the sheet conveying direction, thereby moving a position of an end portion of the second rotating member on a side of the large-diameter portion away from the rotating shaft of the first rotating member.
摘要:
A sheet container, which is incorporated in an image forming apparatus, includes a container body having a loading face to load a sheet thereon, an extension unit disposed extendable in a sheet feeding direction with respect to the container body to extend the loading face, a length regulator disposed movable in the sheet feeding direction with respect to the extension unit to regulate a sheet trailing end position in the sheet feeding direction, and a sheet size indicator having a strip-shape provided on the container body along with a moving direction of the extension unit as a reference of a position of the length regulator, having at least one sheet size mark to indicate a size of the sheet, and being variable in length in a longitudinal direction with respect to the container body along with movement of the extension unit.
