Description
Technical field:
The utility model printer concerning foreign affairs at length says it is a kind of thermal printing head.
Background technology:
As everyone knows, generally speaking, thermal printing head (thermal print head is to call TPH in the following text) forms lead electrode on ceramic substrate, forms the heating resistor band on lead electrode.During actual the printing, the direction parallel with the heating resistor band be called leading India side to, vertical with the heating resistor band at grade direction is called secondary Print direction.
Lead electrode is divided into individual electrode and common electrode again by the function difference.Individual electrode one end is connected with the heating resistor band along secondary Print direction, and the other end is connected with control IC.One end of common electrode is connected with the heating resistor band along secondary Print direction, and the other end is linked together by the lead pattern, and the lead pattern that connects common electrode is called the reinforcement common electrode, and the reinforcement common electrode is connected with outer signal.The part that individual electrode and common electrode are connected with the heating resistor band to mutual arrangement, is divided into several resistance unit with the heating resistor band along leading India side, is called heat generating spot.
Above-mentioned a plurality of heat generating spots are adstante febre simultaneously, and the electric current that each heat generating spot produces will be simultaneously by the reinforcement common electrode.Like this, for reducing the energy loss on the reinforcement common electrode, needing increases the live width and the thickness of reinforcement common electrode.
Usually above-mentioned reinforcement common electrode, heating resistor band, the position of control IC on ceramic substrate are closed and be: at least a portion of reinforcement common electrode is parallel with the heating resistor band, be positioned at a side of heating resistor band with the reinforcement electrode of heating resistor band parallel portion, IC is positioned at the opposite side of heating resistor band, that is to say, at secondary Print direction, reinforcement electrode and IC lay respectively at heating resistor band both sides.Destroyed for preventing IC, need IC to be protected with resin etc.
Above-mentioned thermal printing head, if heating resistor band and potting resin not at a distance of enough distances, potting resin can hinder printing.For making heating resistor band and potting resin keep enough distances economically, need make the edge of the as close as possible reinforcement common electrode one side ceramic substrate parallel of heating resistor band with the heating resistor band.But the reinforcement common electrode need keep certain width to reduce energy loss as far as possible, mean that the heating resistor band is restricted to the close of edge of the reinforcement common electrode one side ceramic substrate parallel with the heating resistor band, usually the edge of heating resistor band and reinforcement common electrode one side ceramic substrate along the vertical range of secondary Print direction more than 1.5mm, use ceramic substrate to be affected like this, economically.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of brand-new lead electrode arrangement mode is provided, the heating resistor band is shortened to below the 0.1mm near a parallel with it side group panel edges vertical range, can realize the thermal printing head of zero distance during limiting case.
The utility model can reach by following measure:
A kind of thermal printing head, comprise the substrate that constitutes by insulating materials, the lead electrode that forms on the substrate, the heating resistor band that on lead electrode, forms along Print direction, lead electrode is divided into individual electrode and common electrode, individual electrode one end is connected with the heating resistor band along secondary Print direction, the other end is connected with control IC, one end of common electrode is connected with the heating resistor band along secondary Print direction, the other end is connected with the lead pattern, it is characterized in that lead pattern and control IC the same side at the heating resistor band.
The lead pattern that the utility model connects common electrode is called the reinforcement common electrode, the reinforcement common electrode is provided with control IC tie point, individual electrode one end is connected with the heating resistor band along secondary Print direction, the other end is connected with control IC tie point through lead, and control IC tie point and reinforcement common electrode are isolated by insulating barrier.
The utility model along leading India side when ceramic substrate is cut apart, ceramic substrate edge and the vertical range between the heating resistor belt edge near heating resistor band one side can be below 0.1mm, above-mentioned vertical range is 0 during limiting case, have simple in structure, volume is little, use advantages such as ceramic substrate economically.
