Abstract
A thermal recording head which comprises a plurality of heat-generating resistors; an insulation substrate on which a plurality of separate conductors are mounted to be connected to the heat-generating resistors directly or with diodes interposed therebetween; and a 3-ply conductor holder formed of an insulation sheet, an assembly of common conductors mounted on the insulation sheet at a prescribed interval and an insulation layer deposited on the common conductors with a thickness of 2 to 20 microns, and wherein the insulation layer has openings arranged at a prescribed interval; and the insulation substrate is laminated with the conductor holder with the common conductors connected to the separate conductors.
Claims4
A thermal recording head which comprises an insulation substrate;
- a plurality of heat-generating resistors formed on the insulation substrate;
- a plurality of separate conductors mounted on the insulation substrate in a state respectively connected to the resistors connected in series with respective diodes;
- and
- a conductor holder for supporting common conductor connected to the separate conductors, and wherein the conductor holder includes an insulation sheet, common conductors mounted on the insulation sheet in a state separated from each other at a prescribed interval, and an insulation layer deposited on the common conductors and provided with openings;
- said insulation sheet included in the conductor holder having windows aligned with the openings of the insulation layer;
- and the common conductors are connected to the separate conductor through the openings.
