Abstract
In a substantially continuous process, solid ink is melted and deposited on a recording roller where it solidifies as a surface coating. Subsequently, heat is applied selectively and locally to portions of the roller to remelt the ink. A recording chart pressed against the moving roller picks up and retains the melted ink, thereby dots or segments of characters are formed on the recording chart. A plurality of heating means may be used so that printing in a dot matrix is made feasible.
Claims21
A non-impact recording device for recording with ink on a recording medium, comprising:
- a recording member having a coating of ink on the surface thereof, said ink coating being subject to melting;
- means for applying ink to said surface of said recording member to form said coating;
- writing means for melting said ink coating on said recording member surface, said writing means acting directly on said ink coating to melt said coating, intermediate elements being absent;
- transfer means for pressing said recording medium against said coated surface, said melted ink becoming attached to said recording medium where said medium is pressed.
A non-impact recording device for recording with ink on a recording medium, comprising:
- a recording member having at least one heating member on the surface thereof;
- means for applying ink to said at least one heating member on said recording member to form an ink coating on said at least one heating member;
- writing means for heating said at least one heating member, said writing means acting directly on said ink coating to melt said coating, intermediate elements being absent, said heated heating member maintaining said coating in a melted condition;
- transfer means for pressing said recording medium against said inked heating member, said melted ink becoming attached to said recording medium where said medium is pressed.
A non-impact recording device for recording with ink on a recording medium, comprising:
- a recording member having at least one heating member on the surface thereof;
- means for applying ink to said at least one heating member on said recording member to form an ink coating on said at least one heating member;
- writing means for heating said at least one heating member, said heated heating member maintaining said coating in a melted condition;
- and
- transfer means for pressing said recording medium against said inked heating member, said melted ink becoming attached to said recording medium where said medium is pressed,
- said recording member surface moving from said means for applying ink to said transfer means for pressing, said means for applying ink being positioned between said writing means and said transfer means.
A non-impact recording device for recording with ink on a recording medium, comprising:
- a recording member having a coating of ink on the surface thereof, said ink coating being subject to melting;
- means for applying ink to said surface of said recording member to form said coating;
- writing means for melting said ink coating on said recording member surface;
- transfer means for pressing said recording medium against said coated surface, said melted ink becoming attached to said recording medium where said medium is pressed,
- said recording member surface moving from said means for applying ink to said transfer means, said means for applying ink being positioned between said writing means and said transfer means.
A non-impact recording device for recording with ink on a recording medium, comprising:
- a recording member having a coating of ink on the surface thereof, said ink coating being subject to melting;
- means for applying ink to said surface of said recording member to form said coating;
- writing means for melting said ink coating on said recording member surface, said writing means acting directly on said ink coating to melt said coating, intermediate elements being absent;
- first transfer means for pressing a first recording medium against said coated surface, a first portion of said melted ink becoming attached to said first recording medium where said first recording medium is pressed,
- second transfer means for pressing a second recording medium against said coated surface, a second portion of said melted ink transferred by said first transfer means becoming attached to said second recording medium where said second recording medium is pressed.
