Abstract: An image forming apparatus includes a casing, an image forming unit movable between an accommodated position and a shifted position, an actuator, an urging member, a cam, and a contact portion. The actuator includes a pivot shaft and a protrusion protruding therefrom. The protrusion at a standby position crosses a conveyance path and is contactable with a sheet conveyed along the conveyance path. When the image forming unit is at the accommodated position, the contact portion and the cam contact each other and maintain the protrusion at the standby position against an urging force of the urging member. As the image forming unit moves from the accommodated position to the shifted position, the contact portion and the cam move away from each other such that the protrusion pivots from the standby position, by the urging force, to a retracted position at which the protrusion is retracted from the conveyance path.

Abstract: A sheet conveying apparatus includes a conveying roller, a pinch roller, a holding member, and a pressing device. The pinch roller includes a roller shaft and a roller body rotatable relative to the roller shaft. The roller shaft includes a first end portion and a second end portion. The holding member holds the roller shaft movably in a first direction. The pressing device presses the roller shaft in a pressing direction such that the roller body is pressed against a peripheral surface of the conveying roller. The first end portion of the roller shaft has a first contact surface being a planar surface. The second end portion of the roller shaft has a second contact surface being a planar surface. The roller shaft is disposed such that the first contact surface and the second contact surface are oriented in the pressing direction.

Abstract: An image forming apparatus including: a sheet feeding tray configured to support a sheet; and an apparatus main body configured to support the sheet feeding tray so as to be moveable in a direction parallel with a sheet feeding direction, the apparatus main body including a chute configured to guide the sheet that is fed from the sheet feeding tray, wherein the sheet feeding tray includes a guiding member configured to be displaced between an engaging position at which the guiding member engages with the chute and restrains movement of the sheet feeding tray and a separation position at which the guiding member separates from the chute and permits movement of the sheet feeding tray, and wherein the guiding member is configured to guide the sheet that is fed from the sheet feeding tray toward the chute when the guiding member is located at the engaging position.

Abstract: A sheet conveyer, having a sheet supporting plate, a feed roller, a lifting device to move the sheet supporting plate between a separated position and a contacting position, a motor, a sheet guide disposed on the sheet supporting plate to extend orthogonally to an axial direction of a rotation shaft of the feed roller to be movable in the axial direction on the sheet supporting plate, and a contact member disposed in an upper position with respect to the sheet guide, is provided. The sheet guide includes a retractable member movable between a first position, in which the retractable member is located when the sheet supporting plate is in the separated position, and a second position, in which the retractable member is placed by a reaction force from the contact member produced by contact between the sheet supporting plate and the feed roller.

Abstract: An image forming apparatus includes a removable sheet support tray. The sheet support tray includes a sheet support surface providing a sheet support area above the sheet support surface. The support tray also includes a stopper portion movable between a restraining position and a non-restraining position that is a different position from the restraining position. In a state where the stopper portion is located at the restraining position, the stopper portion includes a surface disposed adjacent to and downstream of the sheet support area in a first direction, the first direction extending along at least a portion of the sheet support surface.
