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.
