Abstract:
The liquid ejection apparatus has: a head having a nozzle group including a plurality of nozzles which are aligned in a first direction and performs ejection of resist liquid onto a wiring substrate; a scanning device which causes the head and the wiring substrate to move relatively in the first direction; an ejection control device which controls the ejection of the resist liquid from the head; and a scanning control device which controls the scanning device in such a manner that the head and the wiring substrate are relatively moved only once in the first direction, through a region of the wiring substrate which corresponds to one relative movement in the first direction of the wiring substrate and the scanning device, wherein the ejection control device controls the ejection of the resist liquid from the head to cause the resist liquid to be ejected onto a same position of the wiring substrate sequentially, at prescribed time intervals, from different nozzles of the nozzle group, to deposit the resist liquid ejected onto the same position of the wiring substrate sequentially from the different nozzles of the nozzle group, in such a manner that a resist pattern having a prescribed thickness and a prescribed pattern is formed on the wiring substrate.

Abstract:
The scanning printing apparatus prints an image composed of a plurality of row images in accordance with image signals and each row images is printed while moving in a direction on a recording medium. The apparatus includes a moving unit for moving the apparatus itself on the medium in the one direction, a first ejection head for printing each row image of the image on the medium, a second ejection head for printing predetermined invisible marks which cannot be identified by humans on the medium, a first sensor for detecting the invisible marks printed on the medium and a control unit for controlling the moving unit based on detection results of the first sensor. The printing method prints the image by using the apparatus while correcting a printing position based on a position of the detected invisible marks.
Abstract:
The head position detecting method is applicable to recording with a line head including a plurality of short heads which are arranged in a direction of arrangement of recording elements. The method makes relative movements of the line head and a recording medium in a direction perpendicular to the arrangement direction as at least one pair of first and second short heads adjacent to each other which constitute the line head are operated to perform first recording with at least one recording element on an adjacent side of the first short head and second recording with at least one recording element on an adjacent side of the second short head, thereby obtaining a first and/or second recording patterns and detects, from the first and/or second recording patterns obtained, relative first and/or second positions of the first and second short heads adjacent to each other in the arrangement direction and/or the perpendicular direction. The recording head includes a memory for storing data representing a relationship between the second positions. The image recording apparatus implements the method and/or includes the recording head. The storage medium is loaded with a program executing the above method.
Abstract:
A line head, includes a plurality of short heads, each of which has an array of recording elements arranged in one direction, disposed in the direction of arrangement, wherein the short heads that are adjacent to each other in the direction of arrangement are located at a different position in a direction normal to the direction of arrangement as well as an interval between a recording element of one of said two short heads and a recording element of the other short head, which two elements are adjacent to each other in said direction of arrangement, is set equal to or less than the proper arrangement pitch of the recording elements when viewed from the auxiliary scanning direction. Further, when an image is scanned and recorded using this line head, the driving of the recording elements are controlled according to the proper arrangement pitch of the recording elements and the interval as above in the joint region of two short heads adjacent to each other. With this arrangement, the short heads can easily be arranged and put into registration with each other, whereby a manufacturing process can be simplified, the line head can be fabricated at low cost, and further an image recording method capable of recording an image of high quality by means of this line head can be provided.
Abstract:
An image forming device which, after exposing a silver halide photographic photosensitive material, subjects the silver halide photographic photosensitive material to at least developing and bleaching-fixing processings so as to form an image on the silver halide photographic photosensitive material. The silver halide photographic photosensitive material has, on a support, one or more photographic structural layers. At least one of the photographic structural layers contains at least one color developing agent and at least one dye forming coupler. The image forming device includes a processing solution applying device which applies a processing solution for developing onto only a surface of the silver halide photographic photosensitive material at which surface the one or more photographic structural layers are provided.
Abstract:
An image forming processing in which a minimum necessary amount of a processing solution, including hydrogen peroxide, which is substantially devoid of developing agents, an alkaline processing solution, and/or a post-processing solution is applied by a processing solution applying mechanism and the like serving as a non-contacting applying mechanism. The solutions are applied only on a surface of a silver halide photographic photosensitive material, which surface is provided with a photographic structuring layer having a single layer containing a reducing agent. Accordingly, neither the processing solution nor the post-processing solution is wasted and the photosensitive material can be speedily dried.
Abstract:
Photosensitive material which is a silver halide photosensitive material optimally used for copies of a color film original and the like is coated with developing solution from the nozzle holes of a spray tank. A chamber provided with an internal cavity is disposed on the opposite side of the transporting path to the spray tank with the transporting path sandwiched therebetween. The upper portion of the chamber is covered with a heating plate. The heating plate is pierced with a plurality of suction holes which penetrate from the inside of the chamber to the outside thereof. The unexposed surface of the photosensitive material is suctioned through the suction holes and the heating plate heats the photosensitive material as well as guides the photosensitive material. Downstream of the heating plate on the photosensitive material transporting path D, transporting rollers are disposed for transporting the photosensitive material and for squeezing out developing solution from the photosensitive material.
