Title: Electrothermal ink ribbon
Inventor: SAKAI YOSHIHIKO
IPC: B41J31/05
Filed: 1987-02-25
Abstract: PURPOSE:To prevent spots from spreading and enhance resolution, by providing an electric resistance layer with a multiplicity of through-holes. CONSTITUTION:When a printing electrode 2 and a currentcollecting electrode 3 are brought into contact with an electric resistance layer 1d and a pulsed voltage according to image data is applied between the electrode 2 and the electrode 3, an electric current flows along a path indicated by the broken line. In the path, the part of the layer 1d making contact with the printing electrode 2 is locally heated. The Joule heat thus generated is transmitted in the thickness direction of the layer 1d, is transferred to an ink layer 1a through an energizing support layer 1b, and tends to spread in the directions perpendicular to the thickness direction of the layer 1d. Since through-holes 5 are provided uniformly in the layer 1d, the heat is little transmitted in the directions perpendicular to the thickness direction of the layer 1d. Therefore, the Joule heat generated in the resistance layer 1d in conformity with the cross-sectional shape of the printing electrode 2 is transferred to the ink layer 1a through the support layer 1b, without spreading horizontally. Only the part of the ink layer 1a corresponding to the cross-sectional shape of the electrode 2 is locally heated to be melted, and is transferred onto a recording paper 4.
