Receipt printer configurable for full or partial cut
View Patent ↗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.
1. A scissor cutter comprising:
a moving blade having a fixed range of motion;
an adjustable stationary blade, wherein the adjustable stationary blade is stationary during a cutting operation and is moveable lateral relative to the moving blade to allow a paper tape to be selectively fully cut, when the adjustable stationary blade is positioned for a full cut of the paper tape, or partially cut, when the adjustable stationary blade is repositioned laterally to a partial cut position relative to the moving blade that enables a partial cut of the paper tape; and
a blade carrier to which the adjustable stationary blade is mounted;
wherein the lateral movement of the adjustable stationary blade is limited to movement of the adjustable stationary blade to a full cut position and to a partial cut position, wherein the lateral travel of the blade carrier is limited by stops on a printer mount to which the blade carrier is slidably mounted.
2. The scissor cutter of claim 1 , 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.
