  • Patent number: 7930962
    Abstract: A cutter including a base, a holder, a cutter blade portion, and a laser generator. The holder is supported on the base portion in an upright posture. The cutter blade portion supports a moving blade. The cutter blade portion is supported on the holder movable between an upper position and a lower position. The cutter blade portion is moved into the lower position to cut a workpiece supported on the base using the moving blade. The laser generator is attached to the holder or the cutter blade portion in an orientation to direct at least a portion of the laser light onto a position on the workpiece that is directly beneath the cutter blade portion when the cutter blade portion is in the upper position. Alternatively, a holder has a shaft support portion, and a slide shaft is axially slidably supported by the shaft support portion. A front end of the slide shaft has a hinge holder which pivotally supports the cutting blade portion. A laser generator is fixed to a front side of the hinge holder.
