Abstract
A cutting pen with a bar-shaped cutter having a blade portion at one end thereof and a cylindrical holder into which the bar-shaped cutter can be inserted from the other end of the bar-shaped cutter. The holder has a radial bearing disposed corresponding to one end of the bar-shaped cutter and a thrust bearing disposed corresponding to the other end to support the inserted bar-shaped cutter in such a manner as to allow rotation around the axis thereof. The cylindrical holder attracts and holds therein the bar-shaped cutter by magnetic attraction, in such a manner that the work of attaching and/or detaching the bar-shaped cutter can be performed simply and easily in a short time, and the bar-shaped cutter is held firmly preventing it from falling off the cylindrical holder during use of the cutting pen.
Claims17
A cutting pen comprising:
- a bar-shaped cutter having an edged part at one end and a conical pivot at another end;
- a cylindrical holder adapted to receive another end of said bar-shaped cutter;
- a radial bearing disposed in said cylindrical holder at a position corresponding to said one end of said bar-shaped cutter;
- a thrust bearing comprising a pivot bearing disposed in said cylindrical holder at a position corresponding to said other end of said bar-shaped cutter to support said bar-shaped cutter after insertion in said cylindrical holder, adapted to permit rotation of the cutter around an axis thereof, wherein said cylindrical holder attracts and holds said bar-shaped cutter by magnetic attraction.
A cutting pen for a cutting apparatus comprising:
- a bar-shaped cutter having an edge part on a first end;
- a cylindrical holder adapted to permit the insertion of a second end of said bar-shaped cutter, wherein said first end of said bar-shaped cutter extends externally from said cylindrical holder;
- means for preventing deviation of said first end of said bar-shaped cutter from a center axis of said bar-shaped cutter;
- and
- means to magnetically support said second end of said bar-shaped cutter in said cylindrical holder,
- said means to magnetically support comprising a thrust bearing adapted to engage said second end of said bar-shaped cutter inserted in said cylindrical holder, wherein said thrust bearing is further adapted to permit rotation of said bar-shaped cutter around said center axis of said bar-shaped cutter, and further wherein said bar-shaped cutter is further provided with a conical pivot adapted to be engaged with said thrust bearing.
