    摘要: A thin-film type thermal print head has a resistor layer formed over an insulative substrate, a conductor layer having a specified planar pattern overlapping the resistor layer, a portion of the resistor layer serving as a heat-emitting part which is not covered by the conductor layer, and a protective layer formed over the heat-emitting part and at least a portion of the conductor layer adjacent to the heat-emitting part. The protective layer may be formed as a conductive layer with resistance greater than that of the heat-emitting part such that static electricity which may be generated by the friction with printing paper can quickly escape to the conductor layer. The protective layer may also include a wear-resisting layer of a prior art type between the conductive layer and the conductor layer, a portion of the conductive layer being preferably connected to the conductor layer. The conductive layer is preferably a mixed layer of SiC and ZrB.sub.2 containing ZrB.sub.2 by 5-20 molar %, formed by sputtering or chemical vapor deposition and having surface resistance of 10.sup.6 -10.sup.9 .OMEGA..

    摘要: A thermal printhead according to the present invention includes an insulating head substrate (8) having an obverse surface (8a), a reverse surface (8b), a first longitudinal edge surface (8c) and a second longitudinal edge surface (8d). The surface (8a) of the head substrate (8) is formed with an array of heating dots (10a) along the first longitudinal edge surface (8c), a common electrode pattern (11) electrically connected to the array of heating dots (10a) adjacent to the first longitudinal edge surface (8c) and individual electrodes (12) extending away from the common electrode pattern (11) and being electrically connected to the respective heating dots (10a). The heating dots (10a) are selectively heated by drive elements. The common electrode pattern (11) is electrically connected to an auxiliary electrode layer (14) which covers at least the first longitudinal edge surface (8c), reverse surface (8b) and second longitudinal edge surface (8d) of the heat substrate (8).

    摘要: An optical printhead includes a light source, a light guide, and a light collecting sheet. The light guide includes a light incident surface facing the light source and a flat light emitting surface extending in a primary scanning direction. The light collecting sheet faces the light emitting surface of the light guide and allows the passage of light emitted from the light emitting surface. The collecting sheet includes a prism layer formed with a plurality of ridges extending parallel to each other, and a base layer laminated on the prism layer. Diffused light rays emitted from the light emitting surface of the light guide pass through the light collecting sheet to become parallel rays.
