Abstract

A cutter apparatus is provided that includes a fixed blade and a movable blade positioned facing the fixed blade, and that is configured to cut a medium transported between the fixed blade and the movable blade. The movable blade includes: a guide portion that is driven to reciprocate between a standby position at a distance from the medium and a cutting position, where the movable blade intermeshes with the fixed blade, protrudes further toward the movable blade than a cutting edge of the fixed blade when the movable blade is in the standby position, and is pressed by the movable blade to move in a state of being contact with the fixed blade when the movable blade is in the cutting position; and a biasing member configured to bias the guide portion toward the fixed blade.

Claims7

Dependent claims

A cutter apparatus for cutting a medium by a first blade and a second blade, the first blade moving between a standby position and a cutting position, the cutter apparatus comprising:

a guide portion configured to protrude further toward the first blade than a cutting edge of the second blade when the first blade is in the standby position,
a first urging member configured to urge the guide portion toward the second blade,
wherein, when the first blade moves from the standby position to the cutting position, the guide portion is pressed by the first blade to move in a state of contacting with the second blade,
wherein the second blade includes a curvature in which both ends of the second blade are lower relative to a center portion of the second blade in a transport direction of the medium, and
wherein when the first blade moves to the cutting position and intersects with the second blade, the second blade flexes, thereby causing the curvature of the second blade to change conforming to the first blade.
