Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image recording apparatus and a color proof creating apparatus for recording an image by loading a roll-shaped recording material.
[0002]
[Prior art]
In recent years, color separation network original film is not cut from pasted film, but from image data such as character net original image data, photo net original image data, solid image net original image data, etc., color-separated by a device called DTP. Then, color separation network original image data is created by cutting and pasting on the image data, and a device called an image setter is used to create a color separation network original film from the color separation network original image data, or a device called CTP. Directly creating a printing plate has been done.
[0003]
The calibration work performed in such a system using DTP includes not only a method of creating a color separation network original film from color separation network original image data and creating a color proof from the color separation network original film, but also a color separation network. Recently, DDCP for creating a color proof directly from document image data has been performed.
[0004]
In this DDCP, based on color separation network original image data, a silver halide color photographic light-sensitive material is exposed by an LED or a laser beam to create a color proof, based on color separation network original image data. There are those that create a color proof by an ink transfer printing method, and those that create a color proof by an ink jet printing method based on color separation network original image data.
[0005]
An image recording apparatus for recording an image on such a roll-shaped recording material includes a recording material light-shielding cover that can be opened and closed from the front side to the back side of the apparatus body and has a light-shielding cover opening on the lower side, and a roll A set part for inserting and loading the leading end of the recording material into the recording material insertion port by pressing the material drawing port of the recording material box for storing the recording material in a downward direction along the light shielding cover opening and then pushing from the front side to the back side; Some have a pair of conveying rollers for pulling out the loaded recording material in the conveying direction, and a cutter unit that cuts after a predetermined amount of the leading end of the recording material is pulled out.

Further, there is no material box guide guide, and the conveyance guide guide also changes only in the vertical gap, and the material width direction, that is, the distance from the front side to the back side of the light shielding cover opening is constant.
[0007]
[Problems to be solved by the invention]
By the way, if the curling of the recording material is strong when the winding core curl side of the conveying roller pair is strong, the leading edge is easily caught, and after the recording material box is loaded, the corner of the recording material breaks and causes conveyance jam.

In this way, the gap between the material guide guide pair 1100 provided between the recording material box 10 and the conveyance roller pair 21 is inclined so as to become narrower on the conveyance roller pair 21 side, and from the front side of the light shielding cover opening 9b to the back side. Since the front gap of the material guide guide pair 1100 is wider than the back side, the recording material P is strongly curled and can be smoothly inserted without being bent due to contact with the tip P1.
[0068]
After the recording material box 10 is loaded, the fastening bolt 1000c is loosened to move the recording material box guide guide 1000, the inclined guide 1000b is pressed against the front side of the recording material box 10, and tightened with the fastening bolt 1000c. Fix it. In this way, the recording material box guide guide 1000 is also used as a recording material box fixture for restricting the movement of the recording material box 10. Thus, the recording material box guide guide 1000 can be pressed and fixed to the recording material box 10 after loading the recording material box 10 easily and reliably without increasing the number of parts.
[0069]
The base plate 1000a of the recording material box guide guide 1000 is provided with a manual feed opening 1000a1 for taking out the box at the center. When the recording material box 10 is replaced, the recording bolt 10c is loosened for recording. The recording material box 10 can be easily lifted and replaced by moving the material box guide 1000 to the front side and the box taking-out manual opening 1000a1.

【The invention's effect】
As described above in detail, in the first aspect of the invention, since the recording material box is provided with the recording material box guide guide for guiding the recording material box from the front side to the back side of the light shielding cover opening, the lower end portion of the recording material box is provided. Is placed on the recording material box guide, the leading end of the recording material is inserted into the recording material insertion slot, and is pushed from the near side to the far side along the opening of the light shielding cover.
[0071]
According to the second aspect of the present invention, the recording material box guide guide is inclined from the front side to the back side of the light shielding cover opening, and the recording material box is pushed from the front side to the back side along the light shielding cover opening. Guidance can be ensured and the structure is simple.
[0072]
According to the third aspect of the present invention, since the height of the recording material box guide is longer than the distance from the loaded recording material outlet to the center of the conveying roller pair, the leading edge of the recording material contacts the peripheral member of the apparatus. You can safely load without any trouble.
[0073]
In the invention according to claim 4, the roller on the core curl side of the recording material of the conveying roller pair is a roller made of a material having low frictional resistance and good slidability, and the roller opposite to the core curl is made of a material having high frictional resistance. Even if the tip of the recording material comes into contact with a roller made of a material having low frictional resistance and good slipperiness, it can be smoothly inserted between the pair of conveying rollers.
[0074]
In the invention according to claim 5, the gap between the material guide guide pair provided between the recording material box and the conveyance roller pair is inclined so as to be narrowed on the conveyance roller pair side, and from the front side of the light shielding cover opening to the back side. Since the front gap of the material guide guide pair is wider than the back side, the recording material can be smoothly inserted even if the curling of the recording material is strong.
[0075]
In the invention of claim 6, the recording material box guide guide is also used as a recording material box fixture for restricting the movement of the recording material box, and after the recording material box is loaded without increasing the number of parts, the recording material box guide is used. The material box guide can be fixed by pressing it against the recording material box.
[0076]
According to the seventh aspect of the present invention, the box opening manual feed opening is provided at the center of the recording material box guide, so that the box can be easily lifted and replaced by the box take-out manual opening.
[0077]
In the invention described in claim 8, since the cylinder rotates around the cylinder axis while holding the recording material fixedly on the cylindrical holding surface, the image recording surface of the recording material is at a predetermined position. The distance between the tip of the exposure head and the image recording surface of the recording material can be very narrow, and the accuracy of the mounting position and direction of the exposure head with respect to the image recording surface of the recording material is extremely high. Therefore, it is possible to record a high-definition image with extremely high reproducibility and to create a color proof that can be used favorably for calibration.
