  • Patent number: 5903297
    Abstract: Disclosed is a thermal recording apparatus for forming a desired visual image on a recording medium disposed on the opposite side, by utilizing a thermal energy of heating elements provided on a substrate. In the thermal recording apparatus using a thermal head comprising a plurality of substrates on which the heating elements are arranged in line, the joint section of these substrates is positioned in an auxiliary information recording area outside of the image recording width, thus enabling to increase the recording width without deteriorating the recording quality of a visual image to be recorded. That is, in the present invention, one substrate is at least as wide as the image recording area, and another substrate having heating elements also disposed in line is connected to both sides, or one side, of the substrate for image recording, thereby enabling recording the image nearly at the center of the recording medium and also recording an auxiliary information of the image in a margin.
