Printer with cutter unit having blade with adhesion-retardant agent

1. A cutter unit applicable to a printer including a conveying mechanism to convey a print paper in a conveying direction during printing having a print surface and an adhesive surface comprising:

a first blade provided on a conveying path of the print paper conveyed by the conveying mechanism to face the print surface of the print paper; and

a second blade provided on the conveying path to face the adhesive surface, the second blade including a cutting surface configured to slide on a cutting surface of the first blade to cut the print paper inserted between the second and first blades, a contact surface configured to be coated with an adhesion-retardant agent and contact the adhesive surface of the print paper on the conveying path, and an inclined surface extending longitudinally down from the cutting surface of the second blade and inclined to be gradually further away from the first blade in the conveying direction of the print paper throughout an entire cutting process, wherein the inclined surface of the second blade is coated with an adhesion-retardant agent.

2. The cutter unit of claim 1 , wherein the second blade is entirely coated with an adhesion-retardant agent except for the cutting surface.

3. The cutter unit of claim 1 , wherein the contact surface includes a recess portion.

4. A printer comprising:

a conveying mechanism configured to convey a print paper in a conveying direction during printing having a print surface and an adhesive surface;

a printing mechanism provided on a conveying path to print an image on the print surface;

a first blade provided on the conveying path of the print paper conveyed by the conveying mechanism to face the print surface of the print paper; and

a second blade provided on the conveying path to face the adhesive surface, the second blade including a cutting surface configured to slide on a cutting surface of the first blade to cut the print paper inserted between the second and first blades, a contact surface configured to be coated with an adhesion-retardant agent and contact the adhesive surface of the print paper on the conveying path, and an inclined surface extending longitudinally down from the cutting surface of the second blade and inclined to be gradually further away from the first blade in the conveying direction of the print paper throughout an entire cutting process, wherein the inclined surface of the second blade is coated with an adhesion-retardant agent.

5. The printer of claim 4 , wherein the second blade is entirely coated with an adhesion-retardant agent except for the cutting surface.

6. The printer of claim 4 , wherein the contact surface includes a recess portion.

7. A printer comprising:

a conveyer configured to convey a print paper in a conveying direction during printing having a print surface and an adhesive surface;

a printing mechanism configured to print an image on the print surface;

a first blade provided to face the print surface of the print paper; and

a second blade provided to face the adhesive surface of the print paper, the second blade including a cutting surface configured to slide on a cutting surface of the first blade to cut the print paper inserted between the second and first blades, a contact surface configured to be coated with an adhesion-retardant agent and contact the adhesive surface of the print paper, and an inclined surface extending longitudinally down from the cutting surface of the second blade and inclined to be gradually further away from the first blade in the conveying direction of the print paper throughout an entire cutting process, wherein the inclined surface of the second blade is coated with an adhesion-retardant agent.

8. The printer of claim 7 , wherein the second blade is entirely coated with an adhesion-retardant agent except for the cutting surface.
