Abstract

PURPOSE:To provide a liquid jet recording head which does not foul an electric contact point with ink flowing down from an orifice and creates a stable ink discharge state by installing an electric contact point for input to an energy generating element on the same surface as the orifice and at the upper part. CONSTITUTION:A recording head 2 is equipped with an electric wiring substrate 6 which is equipped with an electric contact point 8 on the upper part. At the same time, an orifice plate 12 having an orifice 10 is installed on the lower part. Thus a liquid jet recording head intended for can be obtained.

た。Generally, in a liquid jet recording apparatus, it is desirable that the recording head (hereinafter referred to as the recording head) be easily attached to and removed from the carriage for reasons such as maintenance and replacement of the liquid jet recording head. 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 that ejects 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 orifice surface for the above-mentioned reason. As a result, ink spilled from the orifice stains the electrical contacts, causing corrosion or poor contact, resulting in inconveniences such as the liquid (ink) not being ejected or the ejection condition being unstable. did.

である。FIG. 1 is a perspective view of a recording head 2 according to this embodiment,
The recording head 2 is mounted in this state on a carriage (not shown). A reservoir 4 filled with ink or the like is formed inside the recording head 2, and an electric wiring board 6 is provided on the surface that comes into contact with a carriage (not shown). The electric wiring board 6 is for supplying driving power to energy generating elements (not shown) inside the recording head 2. Further, an electrical contact 8 is provided on the upper part of the electrical wiring board 6, and the electrical contact 8
An orifice plate 12 having an orifice 1o is provided below. Note that 14 is a wiring conductor, and 16 is a discharged droplet (ink).
It is.

い。When the recording head 2 configured as described above is mounted on a carriage (not shown), it is mounted so that the electrical contacts on the carriage side are in contact with the electrical contacts 8. Driving power and control signals are then transmitted from the carriage side through the electrical contacts, and droplets 16 are ejected from the orifice 10 to perform recording. At this time, since the electrical contact 8 is located above the orifice 1o, the electrical contact 8 is not contaminated by ink flowing out from the orifice 1o.

。As described above in detail and specifically, according to the present invention,
Since the electrical contacts are located above the orifice, the electrical contacts are not contaminated or corroded by ink that has flowed down from the orifice, so the electrical contacts can always maintain a good contact state, and as a result, the recording spatula p has the remarkable effect that a stable liquid ejection state can always be obtained.
