Abstract: A handheld punching device includes an operating grip pivotably connected to a holding grip to have a loading end turned in an up-down direction, a transmitting lever pivotably connected to the loading end to transmit a torque to turn a driving end, a punching seat pivotably connected to the holding grip and defining a cutting space for receiving a workpiece to be punched, and a plurality of punch units disposed between the driving end and the punching seat and each having a punch head movably and fittingly disposed in the punching seat along a straight path in the up-down direction, and a press head in abutting engagement with the driving end to be moved by the torque and to drive movement of the punch head through the cutting space for creating a hole in the workpiece.

Abstract: A method, system and computer readable media relating to automatically adjusting a graphics feature to compensate for a predetermined resolution limit. The method generally relates to automatically identifying, within a selected area of a graphics file, one or more portions of at least one graphics feature meeting predetermined criteria for adjustment, including criteria for defining a thin portion having a thickness less than the resolution limit. The method then automatically modifies only the identified one or more portions to have an adjusted thickness greater than the initial thickness. Additional criteria may be used to restrict which thin portions of the feature are actually modified.

Abstract: A stamp device employs a heat sensitive stencil paper which includes a thermoplastic film and a porous carrier. The heat sensitive stencil paper is perforated by a thermal head according to characters, symbols, figures, etc. of an image input from an input mechanism. The display can be controlled to display a layout of the image to be perforated on the heat sensitive stencil paper. Therefore, a user can determine whether the layout is acceptable prior to perforating the stencil sheet. Consequently, the user can accurately print at a desired position on a recording medium by confirming the layout on the display prior to printing.

Abstract: In a printing-plate preparation apparatus employed in a screen printing machine comprising a thermal printhead provided with a heating-element portion, a rotatably supported platen roller for delivering a stencil paper and urging the same against a surface of the heating-element portion of the thermal printhead, and a manuscript-reading unit movable back and forth between a first position and a second position an improvement resides in that an outer peripheral surface of the platen roller is made of non-adhesive material while urged against a surface of the heating-element portion of the thermal printhead, whereby the stencil paper is clamped between the platen roller and the thermal printhead so as to be delivered while subjected to a perforation operation conducted by the heating-element portion of the thermal printhead.
