Description

【考案の詳細な説明】 （産業上の利用分野） この考案はサーマルプリントヘッドに関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a thermal print head.

（従来の技術） 周知のようにこの種サーマルプリントヘッドは、基板の
表面に発熱体を設置するとともに、これに通電するため
のコモンパターンおよび個別パターンを形成して構成さ
れている。このパターン特に個別パターンを検査するの
に、基板に光を透過させ、その透過光からパターンを識
別して検査することが行なわれている。(Prior Art) As is well known, this type of thermal print head is configured by installing a heating element on the surface of a substrate and forming common patterns and individual patterns for energizing the heating element. In order to inspect this pattern, especially an individual pattern, light is transmitted through the substrate, and the pattern is identified from the transmitted light to inspect it.

一方この種のヘッドにおいて、基板の端面またはその近
辺の端縁に発熱体を設置して構成するものがあり、その
場合基板の、互いに向かい合う表面のうちの、一方の表
面にその全表面にわたってコモンパターンを、他方の表
面に個別パターンを形成するようにしている。On the other hand, in this type of head, there is one in which a heating element is installed on the end face of the substrate or an edge in the vicinity thereof, and in that case, one of the surfaces of the substrate facing each other has a common surface over the entire surface. The pattern is adapted to form an individual pattern on the other surface.

しかしこのようにパターンを形成すると、個別パターン
の識別のために一方の表面から個別パターンが形成され
てある他方の表面に向けて、光を透過させようとして
も、コモンパターンが基板の一方の全表面に形成してあ
るため、光はこのコモンパターンを透過することができ
ない。そのため個別パターンの検査が不可能となる欠点
がある。However, when the pattern is formed in this way, even if an attempt is made to transmit light from one surface to the other surface on which the individual pattern is formed for the purpose of identifying the individual pattern, the common pattern is formed on one side of the substrate. Since it is formed on the surface, light cannot pass through this common pattern. Therefore, there is a drawback that the inspection of individual patterns becomes impossible.

（考案が解決しようとする問題点） この考案はサーマルプリントヘッドの基板の、互いに向
かい合う表面のうちの、一方の表面にコモンパターン
を、他方の面に個別パターンを形成した場合でも、個別
パターンの透過光による識別を可能とすることを目的と
する。(Problems to be Solved by the Invention) Even when the common pattern is formed on one surface of the substrates of the thermal print head facing each other and the individual pattern is formed on the other surface of the substrate of the thermal print head, The purpose is to enable identification by transmitted light.

（問題点を解決するための手段） この考案はコモンパターンの表面の複数個所に、個別パ
ターン識別用の光を基板に透過させるように入射させる
空所を設けたことを特徴とする。(Means for Solving the Problems) This invention is characterized in that a plurality of locations on the surface of the common pattern are provided with cavities through which light for identifying individual patterns is made incident so as to pass through the substrate.

（実施例） この考案の実施例を図によって説明する。図において１
はセラミックなどからなる基板で、その端面またはその
近辺の端縁に、プリント用の発熱体２が設置されてあ

に通電するためのリードである。(Embodiment) An embodiment of the present invention will be described with reference to the drawings. 1 in the figure
Is a substrate made of ceramic or the like, and a heating element 2 for printing is installed on the end face or an end edge in the vicinity thereof, and the common pattern 4 is provided on one surface 3 of the surfaces of the substrate 1 facing each other. The individual pattern 6 is formed on the other surface 5. Each pattern has a heating element 2
It is a lead for energizing.

これらの構成は通常のこの種ヘッドと特に相違するもの
でないが、この考案にしたがい、コモンパターン４の表
面の複数個所に空所たとえば孔７を形成しておく。この
孔７は個別パターン６を検査のために識別するのに使用
する光を、表面３から表面５に向けて入射するのに使用
する。Although these structures are not particularly different from those of a normal head of this type, according to the present invention, voids, for example, holes 7 are formed in a plurality of positions on the surface of the common pattern 4. The holes 7 are used to direct the light used to identify the individual patterns 6 for inspection from the surface 3 towards the surface 5.

すなわち前記のように表面３から表面５に向けて、孔７
より光を入射させると、その光は基板１を透過して表面
５に至る。したがって表面５を外部から観察すると、個
別パターン６がシルエットのように浮び上がる。これを
光学的に観察することによって、個別パターン６を検査
することができるようになる。That is, as described above, the holes 7 are formed from the surface 3 to the surface 5.
When more light is made incident, the light passes through the substrate 1 and reaches the surface 5. Therefore, when the surface 5 is observed from the outside, the individual pattern 6 emerges like a silhouette. By observing this optically, the individual pattern 6 can be inspected.

なおこの考案による空所は、孔に限られずたとえば切欠
き状のものであってもよく、また単一の孔パターンで形
成してもよい。The cavity according to the present invention is not limited to a hole, but may be, for example, a notch, or may be formed with a single hole pattern.

（考案の効果） 以上詳述したようにこの考案によれば、基板の各表面に
コモンパーン、個別パターンを形成したヘッドであって

となる効果を奏する。(Effect of the Invention) As described in detail above, according to the present invention, even with a head having a common pattern or an individual pattern formed on each surface of the substrate, it is possible to perform an inspection by discrimination by the transmitted light of the individual pattern. Play.
