A movement and rotational movement of the movable blade of the paper-cutter of this invention is constructed with a mechanically engaging mechanism such as a screw mechanism or a pinion/rack mechanism, so that there are no technical problems found with the conventional type of the paper-cutters such as slackening and/or cutting-off of the wire and coming-off of the wire from the drum. Moreover, since it is not neces

A paper cutter that includes: an elongated enclosed housing that further includes a top wall, a bottom wall, a back wall, an open front and a pair of opposed end walls, a lead screw rotatably mounted in said end walls with one end of said lead screw passing through one end wall of the housing, said lead screw being positioned between said top wall and said bottom wall, a moving member mounted on said lead screw within the housing that is arranged to reciprocate laterally within the housing between said end walls, a stationary blade mounted in spaced-apart relationship with the bottom wall of the housing to define a paper path therebetween, said stationary blade having a linear cutting edge that extends outwardly beyond the open side of said housing along the bottom wall, a rack means mounted inside the housing along the bottom wall parallel to the cutting edge of the stationary blade, a rotatable blade mounted in the moving member by a shaft means that passes through the open side of said housing, said rotating blade being arranged to coact with the cutting edge of the stationary blade to cut a sheet of paper positioned between the blades, motor means fixedly mounted on said one end wall of said housing, said motor means being connected to said one end of the lead screw to turn said lead screw and move the carriage laterally within said housing, and pinion means mounted on said shaft means for connecting said rotatable blade to said rack means to coordinate the rotatable blade movement with the movement of the moving member to cut a sheet in said paper path between said blades.
