Cutter and printer with cutter

摘要

A cutter and a printer having a cutter prevent the paper pieces cut off by the cutter from collecting at the paper exit from which the cut-off pieces are discharged. A stage surface 40defines the bottom edge 5a of the paper exit 5. A sloped guide surface 41 is formed sloping down from the downstream side of the stage surface 40. A first side wall 42 determines where one side of the width of the paper passes over the stage surface 40 and the sloped guide surface 41. A second side wall 43 determines where the other side of the width of the paper passes. A protrusion 47 is formed on the first side wall 42 protruding toward the second side wall 43.When label paper 11 is cut, the cut-off portion 11c is deposited on the stage surface 40 covering the top of the protrusion 47. As a result, the cut-off portion 11c is made unstable by the protrusion 47 immediately after being deposited on the stage surface 40, and slides down easily. The cut-off portion 11c slides down from the stage surface 40 along the sloped guide surface 41, and is discharged smoothly from the paper exit 5.

主权项

1. A cutter comprising:
a fixed knife; a movable knife that moves relative to the fixed knife and cuts paper; a paper exit from which a paper is discharged in a discharge direction, the paper having a paper width transverse to the discharged direction; a stage surface that defines a bottom surface of the paper exit, the stage surface having a first and second side; a first side wall on the first side of the stage surface; a second side wall on the second side of the stage surface and opposite the first side wall; at least one first protruding part disposed to the stage surface and the first side wall and extending transverse to the discharge direction by less than the paper width so as to support the paper over less than the width of the paper; at least one second protruding part disposed on the stage surface and extending in the discharge direction; and an inclined guide surface formed at a downstream side of the stage surface relative to the discharge direction, the inclined guide surface extending down in the discharge direction, wherein the inclined guide surface and the at least one protruding part causes the paper to discharge in the downstream direction.
