Abstract
A printer includes a main body case in which a sheet roll is installed, a sheet discharge port from which a printed sheet of paper is discharged, an opening/closing cover that opens and closes with respect to the main body case, a cutter that is attached to the opening/closing cover and configured to cut the printed sheet of paper from the sheet roll, and a cutter protection mechanism configured to move in correspondence with an opening movement or a closing movement of the opening/closing cover. The cutter protection mechanism is configured to expose the cutter at the sheet discharge port when the opening/closing cover is in a closed state and conceal the cutter when the opening/closing cover is in an open state.
Claims2
A printer comprising:
- a main body case in which a sheet roll is installed;
- a sheet discharge port from which a printed sheet of paper is discharged;
- an opening/closing cover that opens and closes with respect to the main body case;
- a cutter that is attached to the opening/closing cover and configured to cut the printed sheet of paper from the sheet roll;
- and
- a cutter protection mechanism configured to move in correspondence with an opening movement or a closing movement of the opening/closing cover;
- wherein the cutter protection mechanism is configured to expose the cutter at the sheet discharge port when the opening/closing cover is in a closed state and conceal the cutter when the opening/closing cover is in an open state,
- wherein the cutter is attached to the opening/closing cover in a manner such that the cutter is unable to move,
- wherein the cutter protection mechanism includes a shutter that is movable with respect to the opening/closing cover, and
- wherein the shutter is configured to expose the cutter in correspondence with the closing movement of the opening/closing cover and conceal the cutter in correspondence with the opening movement of the opening/closing cover,
- wherein the cutter protection mechanism further includes
- a rack gear that is fixed to an end part of the shutter,
- a pinion gear configured to mesh with the rack gear and rotate relative to the rack gear,
- an urging part configured to urge the cutter or the pinion gear in a direction causing the shutter to cover the cutter, and
- a rib that is formed on an inner side surface of the main body case,
- wherein the pinion gear includes a rod part projecting from a peripheral surface of the pinion gear,
- wherein the rib is configured to rotate the pinion gear by exerting pressure on the rod part during the closing movement of the opening/closing cover and move the shutter to a position that exposes the cutter at the sheet discharge port.
