    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： A sheet cutting device includes a cutter holder, a moving unit, a connecting member, and a drawing 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. The moving unit is disposed away from the cutter holder in a sheet feed direction in which the sheet is fed along the sheet feed path. The moving unit is reciprocally movable in a sheet width direction perpendicular to the sheet feed direction. The connecting member connects the cutter holder to the moving unit. The drawing member is mounted on the moving unit to draw the moving unit in the sheet width direction. The cutter holder is pivotable around the connecting member in a thickness direction of the sheet relative to the moving unit.

    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.
