AUTO CUTTER DEVICE AND PRINTER

摘要

PROBLEM TO BE SOLVED: To cut a pair of individually fed paper-like materials by a single movable blade member in an auto cutter device cutting paper-like materials. SOLUTION: This auto cutter device 10 is provided with one movable blade member 16 having a knife blade 14 on an outer edge, and a driving mechanism 18 rotatively driving the movable blade member 16 for cutting printing paper M by the knife blade 14. The movable blade member 16 has a rotational center axis 16a in a position adjacent to the knife blade 14. The knife blade 14 has linear first blade portion 14a and second blade portion 14b on both sides of a virtual plane including the rotational center axis 16a. These first and second blade portions 14a and 14b are extended in directions where they obtusely intersect each other with an intersection point near the rotational center axis 16a. The driving mechanism 18 rotates the movable blade member 16 in a desired directionαaround the rotational center axis 16a for having the first and second blade portions 14a and 14b of the knife blade 14 selectively perform cutting action.
