Abstract
In a stamping device, a stamping stencil is produced and used which does not require manual application of ink to the stencil. Data concerning an image, which may include character, figure and/or symbol data, is input by a input unit, a thermal head generates heat on the basis of the data and transmits the heat to the thermal stencil paper disposed at the printing position. As a result, a corresponding pattern of pores is produced, by the heat of the thermal head, in the thermal stencil paper. Ink is supplied to the pores by an ink supply unit at an ink supplying position when pressure is applied to the back of the ink supply.
Claims31
A portable stamping device, comprising:
- a stencil producing unit further comprising:
- data input means providing a plurality of characters for enabling an operator to selectively input desired ones of the plurality of characters to make up image data to be used to produce a stamping stencil;
- thermal head means for forming pores by heat in a thermal stencil paper at a printing position on the basis of the data input by said data input means;
- and
- stenciling sheet supplying means for supplying the thermal stencil paper from a supply position to the printing position;
- the portable stamping device also comprising means for use of the thermal stencil paper, having pores therein, that is separate from the stencil producing unit, said means for use having an ink supply means for supplying the pores formed in the thermal stencil paper with ink at an ink supplying position and used for printing when separated from said stencil producing unit.
