A scanning optical apparatus is used as a recording apparatus having an optical system and a mechanical system and effecting desired recording on a photoconductor by irradiation of a beam. The apparatus comprises marks confirming the beam scanning position on the photoconductor, an error detecting unit for detecting the error of the scanning position from the optimal scanning position, which error is due to an optical factor or a mechanical factor, and a control unit for suitably correcting the scanning position of the beam in real time on the basis of a signal representing the detected error.

A solid ion recording head using an ion generation device, capable of realizing a uniform and stable recording and a compact physical configuration. The head includes a head support member in substantially rectangular cross sectional shape for supporting the ion generation device on a lower side of the rectangular cross sectional shape facing against the recording medium and the driving circuits on side faces of the rectangular cross sectional shape. The ion generation device includes control electrodes having ion passing holes which are arranged such that picture dot to be recorded on the recording medium from each one of the ion passing holes is recorded on a spot around which picture dots already recorded by other ion passing holes are distributed symmetrically on both sides. The control electrodes may have a structure in which a plurality of the ion passing holes are provided with respect to each picture dot to be recorded.

In the ink jet recording apparatus for recording an image by supplying ink obtained by dispersing color material components in a solvent to a head substrate and by jetting ink drops containing at least the color material components to a recording medium on the basis of electrostatic force applied to the color material components, the recording apparatus comprises a driving circuit (107) for applying voltages to electrodes of an electrode array (102) arranged on a head substrate (101), in such a way that a first potential difference whose potential level relationship is reversed at a predetermined period between the two adjacent electrodes can be applied when the color material components are cohered and/or stirred on the head substrate, and a second potential difference different from the first potential difference between the two adjacent electrodes can be applied when the ink drops are jetted toward a recording medium. In this ink jet recording apparatus, a stable recording can be made by uniformalizing the density of the ink color material components on the head substrate and further by preventing the color material components from adhering onto the electrode.
摘要:
An auxiliary substrate is provided so as to face a main substrate to which ink is supplied and the pattern of a voltage applied to an auxiliary electrode array formed on the auxiliary substrate is controlled. In a printing operation, the coloring material components are sent to the vicinity of an ink droplet emitting outlet and the coloring material components in the ink where the coloring material is dispersed in solvent are concentrated. Then, they are emitted from the ink droplet emitting outlet in the form of ink droplets and are forced to fly at a printing medium, thereby printing on the medium. In a non-printing operation, the auxiliary electrode array is controlled so that the coloring material components may be kept away from the ink droplet emitting outlet and the concentration of the coloring material components in the ink near the ink droplet emitting outlet is made lower than in a printing operation.

摘要:
An ink jet printing apparatus, in which the ink having colorants distributed in a solvent is supplied over the electrode array on the surface of the head substrate such that the electrode array is completely covered by the ink, while voltages are applied to the electrode array to produce an electric field for exerting an electrostatic force on the colorants in the ink such that the colorants are compressed and ejected toward a recording medium. Each individual electrode constituting the electrode array can have a tip end portion projecting from the surface of the head substrate. The apparatus also has an element for compressing colorants distributed in a solvent of an ink and an element for ejecting the compressed colorants toward a recording medium which are provided separately. In addition, the apparatus can incorporate an element for conveying colorants in the ink through the ink supply passage toward the colorant ejection point on the electrode array.
