摘要： An image forming apparatus includes a sheet feed device to feed a sheet along a sheet feed path, a sheet cutting device including a cutter and a cutter holder to cut the sheet to a desired length, a controller to control the sheet feed device and the cutter holder. The cutter holder holds the cutter and is reciprocally movable in a width direction of the sheet perpendicular to a sheet feed direction. The cutter holder, after cutting the sheet, is movable in the width direction with the cutter holder retracted away from the sheet feed path in a thickness direction of the sheet perpendicular to both the sheet feed direction and the width direction. The controller controls the sheet feed device to feed the sheet while the cutter holder moves in the width direction with the cutter holder retracted away from the sheet feed path in the thickness direction.

摘要： An image forming apparatus includes a recording head, a carriage, a sheet cutting device, a cutter position detecting device, and a notification device. The carriage mounts the recording head and is reciprocally movable in a width direction of a sheet perpendicular to a sheet feed direction. The sheet cutting device includes a cutter and a cutter holder. A movement area of the carriage overlaps, in a thickness direction of the sheet, a movement area of the cutter holder in which the cutter holder moves to cut the sheet with the cutter. The cutter holder, after cutting the sheet, is movable in the width direction of the sheet with the cutter holder being retracted from the sheet feed path in the thickness direction of the sheet. The notification device notifies a user of an abnormality of the cutter holder based on a detection result of the cutter position detecting device.

摘要： A sheet cutting device includes a cutter holder, a moving unit, and a guide member. The cutter holder accommodates a cutter. The cutter has opposed blades opposing each other to cut a sheet of recording media fed along a sheet feed path of a feed guide plate unit. The moving unit holds the cutter holder and is movable in a sheet width direction perpendicular to a sheet feed direction in which the sheet is fed along the sheet feed path. The guide member is disposed along the sheet width direction to guide the moving unit in the sheet width direction. The cutter holder partially overlaps with the feed guide plate unit in a thickness direction of the sheet perpendicular to both the sheet width direction and the sheet feed direction.

摘要： A moving unit of a sheet cutting device is movable in a sheet width direction perpendicular to a sheet feed direction in which a sheet of recording media is fed along a sheet feed path. A cutter holder accommodates a cutter, is connected to the moving unit and is rotatable in a thickness direction of the sheet relative to the moving unit. A guide member is disposed along the sheet width direction to guide the moving unit in the sheet width direction. A drawing member is mounted on the moving unit to draw the moving unit toward a downstream side in a cutting direction in which the cutter holder moves to cut the sheet. The moving unit is connected to the cutter holder at a position downstream in the cutting direction from an accommodated position of the cutter in the cutter holder.
