Abstract:
1. A cutter mechanism for cutting a recording sheet, comprising: a fixed blade; a movable blade formed in a substantially V-shape when viewed from above, the movable blade being mounted to undergo sliding movement with respect to the fixed blade so as to ride on the fixed blade during sliding movement for cutting the recording sheet while sandwiching the recording sheet together between the fixed blade and the movable blade; a motor for driving the movable blade; a fixed blade holder that holds the fixed blade with respect to the movable blade in an inclined state so that a cutting edge of the fixed blade forms a predetermined cutting angle with respect to a cutting edge of the movable blade; a holder support member that is orthogonal to a sliding direction of the movable blade and supports the fixed blade holder movably in an orthogonal direction in which the cutting edge of the movable blade moves close to and away from the cutting edge of the fixed blade; a biasing member that is provided between the fixed blade holder and the holder support member and that biases the fixed blade holder in the orthogonal direction so that the cutting edge of the fixed blade is brought into press-contact with the cutting edge of the movable blade; a main unit supporting the movable blade and the motor for driving the movable blade; and a detachable unit separably combined with the main unit, the detachable unit supporting the fixed blade, the fixed blade holder, the holder support member and the biasing member.
