たした。In general, in liquid jet recording devices, liquid jet recording
It is desirable that the recording head can be easily attached to and detached from the carriage for reasons such as maintenance and replacement of the carriage. For this reason, conventionally, in order to supply driving power and signals to the recording head, electrical contacts are provided on the recording head and the carriage, respectively, and when the recording head is mounted on the carriage, the electrical contacts of the two come into contact, and the driving power is supplied to the recording head. It is proposed that the signals are supplied. At this time, the recording head is often mounted on a carriage, and for this reason, electrical contacts on the recording head side are usually provided at the bottom of the recording head. Furthermore, in a recording head in which the orifice surface where the orifice for ejecting ink exists and the electrical wiring board having the electrical contact point are formed on the same plane, the electrical contact point is provided below the geo-orifice surface for the above-mentioned reason. The ink that spills down the orifice stains the electrical contacts, corrodes the electrical contacts, and causes poor contact, resulting in the liquid (ink) not being ejected or the ejection condition becoming unstable. This caused an inconvenience.
そこで本発明の目的は前記欠点を解消すべく常に安定し

することにある。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a liquid jet recording head that can always realize a stable liquid ejection state in order to eliminate the above-mentioned drawbacks.

特徴とする。In order to achieve the above object, the present invention provides a liquid having an orifice provided for ejecting the liquid to form flying droplets, and an energy generator generating energy used to form the droplets. The jet recording head is characterized in that an electrical contact for input to the energy generator is provided on a surface different from the surface on which the orifice is provided.

る。FIG. 1 is a perspective view of a recording head 2 according to a first embodiment of the present invention, and the recording head 2 is mounted in this state on the illustrated carriage. An orifice 4 is provided on the print paper side surface of the recording head 2, and an electrical contact 6 is provided on a surface different from the surface on which the orifice 4 is provided. 8 is a discharged droplet such as ink. In order to mount the recording head 2 on a carriage (not shown), it is mounted so that the carriage-side electrical contacts (not shown) and the electrical contacts 6 are in contact with each other. A drive power signal is then applied to the recording head 2 from the carriage side, and droplets (ink) 8 are ejected from the orifice 4, so that the recording head 2 performs recording. At this time, in the first embodiment, since the orifice 4 and the electrical contact 6 are arranged on different surfaces, it is possible to prevent the electrical contact 6 from being contaminated by ink spilled from the orifice 4.

的接点6のインクによる汚れ等を防止できる。FIG. 2 shows a second embodiment of the present invention, and the feature of this second embodiment is that the electrical contact 6 is provided above the orifice 4. Therefore, it is possible to prevent the electrical contacts 6 from being contaminated by ink to a greater extent than in the first embodiment.

等の他の面に設けることも可能である。Similarly, in the first and second embodiments of the present invention, the electrical contact 6
is provided on the side surface of the recording head 2, but it is also possible to provide it on other surfaces such as the upper surface, the lower surface, or the back surface facing the orifice 4 side of the recording head 2, for example.
以上詳細かつ具体的に説明した如く、本発明によれば、

きるという効果がある。As described above in detail and specifically, according to the present invention,
The simple structure of arranging the orifice and the electrical contact on different surfaces, and furthermore, arranging the electrical contact above the orifice, can cause the electrical contact to become dirty and corrode due to ink spilling from the orifice, resulting in poor contact. This has the effect that it is possible to prevent this from occurring and to maintain a stable droplet ejection state at all times.
