Abstract
A receipt printer having a scissor cutter for cutting off a receipt from a paper roll. The scissor cutter includes a moving blade that articulates across an adjustable stationary blade. The adjustable stationary blade is adjustable laterally according to whether a full cut or a partial cut across the paper roll is desired. If a full cut is desired, the stationary blade is positioned against the full width of the paper roll. If a partial cut is desired, the stationary blade is positioned against only a portion of the width of the paper roll.
Claims19
A paper tape printer comprising:
- a receipt printer that prints receipts on a paper tape;
- and
- a scissor cutter comprising:
- a moving blade mounted to a chassis and having a fixed range of motion around a pivot point;
- an adjustable stationary blade, wherein the adjustable stationary blade is moveable laterally relative to and independent of the moving blade to allow the paper tape to be selectively fully or partially cut, wherein the paper tape is only partially cut when the stationary blade is positioned in a first lateral position by laterally adjusting the position of the adjustable stationary blade to the first lateral position when the stationary blade is not in the first lateral position and the paper tape is fully cut when the stationary blade is positioned in a second lateral position by laterally adjusting the position of the adjustable stationary blade to the second lateral position when the adjustable stationary blade is in the first lateral position;
- wherein only a portion of a width of the paper tape is against the adjustable stationary blade when the adjustable stationary blade is in the partial cut position and an entire width of the paper tape is against the adjustable stationary blade when the adjustable stationary blade is in the full cut position;
- and
- a blade carrier to which the adjustable stationary blade is mounted.

A paper tape printer comprising:
- a receipt printer that prints receipts on a paper tape;
- and
- a scissor cutter comprising:
- a moving blade having a fixed range of motion;
- an adjustable stationary blade, wherein the adjustable stationary blade is moveable laterally relative to the moving blade to allow the paper tape to be selectively fully or partially cut, wherein the paper tape is only partially cut when the stationary blade is positioned in a first lateral position and the paper tape is fully cut when the stationary blade is positioned in a second lateral position;
- a blade carrier to which the adjustable blade is mounted, wherein the blade carrier is Z-shaped, and wherein the blade carrier includes:
- a blade mounting section at a first end of the Z-shaped blade carrier;
- a friction locking section at a second end of the Z-shaped blade carrier;
- and
- a transition section between the first and second ends of the Z-shaped blade carrier, wherein the first end of the Z-shaped blade carrier is normal to the transition section of the Z-shaped blade carrier, and wherein the second end of the Z-shaped blade carrier is normal to the transition section of the Z-shaped blade carrier.

A paper tape printer comprising:
- a receipt printer that prints receipts on a paper tape;
- and
- a scissor cutter comprising:
- a moving blade mounted to a chasis and having a fixed range of motion around a pivot point;
- an adjustable stationary blade, wherein the adjustable stationary blade is moveable laterally relative to and independent of the moving blade to allow the paper tape to be selectively fully or partially cut, wherein the paper tape is only partially cut when the stationary blade is positioned in a first lateral position and the paper tape is fully cut when the stationary blade is positioned in a second lateral position;
- wherein only a portion of a width of the paper tape is against the adjustable stationary blade when the adjustable stationary blade is in a partial cut position and an entire width of the paper tape is against the adjustable stationary blade when the adjustable stationary blade is in a full cut position;
- a blade carrier to which the adjustable stationary blade is mounted, wherein lateral travel of the blade carrier is limited by stops on a printer mount to which the blade carrier is slidably mounted.
