Abstract: A cutter device has a movable blade, a stationary blade, and a clutch mechanism having a driven gear mounted for undergoing rotation in clockwise and counterclockwise directions and a driving gear for rotationally driving the driven gear about a rotational axis. A cutter drive mechanism has a rotation device connected to the clutch mechanism so that through one complete rotation of the driven gear the rotation device reciprocally moves the movable blade between a first region in which the movable blade is spaced apart from the stationary blade and a second region in which the movable blade cooperates with the stationary blade to cut recording paper. A rotation regulating device regulates rotation of the driven gear in the counterclockwise direction when the movable blade is in the first position.

Abstract: To provide a cutter device for a printer in which it is possible, in a printing state in which a movable blade is on standby for movement, to reduce a flicking noise generated between gears and to restrain vibrations generated.
