Patent ID: 8277134

Claim:
A printer with a cutter for cutting a recording sheet pulled out from a paper roll after printing is performed on the recording sheet, comprising: a print head extending in a width direction of the recording sheet; a platen roller having an outer peripheral surface contactable with the print head with the recording sheet being interposed therebetween, the platen roller being mounted to undergo rotation in a rotating direction to feed the recording sheet; a fixed blade disposed adjacent to the platen roller so as to be opposed to the fed recording sheet; a movable blade mounted to undergo sliding movement toward the fixed blade for cutting the recording sheet after printing is performed on the recording sheet; a fixed blade holder disposed between the fixed blade and the platen roller, the fixed blade holder having one surface on which the fixed blade is fixedly supported and another surface opposed to the outer peripheral surface of the platen roller with a gap therebetween, the another surface of the fixed blade holder being curved along the outer peripheral surface of the platen roller and being configured to guide the recording sheet toward a downstream side of the fixed blade holder in the rotating direction of the platen roller when the recording sheet enters the gap between the fixed blade holder and the platen roller; a holder support having a surface opposed to the outer peripheral surface of the platen roller on the downstream side of the fixed blade holder in the rotating direction of the platen roller with a gap therebetween, the holder support being configured for pivotally supporting the fixed blade holder to allow a blade edge side of the fixed blade to be moved in a direction substantially orthogonal to a sliding direction of the movable blade; and a biasing member disposed between the fixed blade holder and the holder support for biasing the fixed blade holder in a direction away from the peripheral surface of the platen roller.
