[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for making a reference hole suitable for a post-processing device in a light-sensitive material output from an image output device.

[0002]

2. Description of the Related Art A light-sensitive material on which an image is output by an image output device is fixed to a printing machine when it is a printing plate, and is fixed to a printing plate device when it is a film for carrying out plate making. (Hereinafter, these printing machines, plate-making devices, etc. are collectively referred to as post-processing devices). When performing color printing, the printing plate output for each color separation plate must be fixed such that the image positions of the color separation plates match each other in any post-processing device.

Conventionally, the following method has been used in order to match the positions of the images on the light-sensitive materials of each color separation plate. First, in the image output device, a marked line called a register mark is output at a fixed position around the image. Sensitive materials of respective colors are overlapped so that the marked lines coincide with each other, and a fixing hole suitable for a post-processing device is formed with a punch. By mounting the light-sensitive material on a post-processing device such as a printing machine or a plate-making device using the holes, the image of each color separation plate is placed at a fixed position.

[0004]

However, in order to eliminate the positional deviation of the image between the color separation plates, it is necessary to precisely align the register marks of the photosensitive material for each color when the holes are punched by the punching device. However, since this is conventionally done visually, sufficient alignment accuracy cannot be obtained.

Therefore, an image output device has been devised in which a perforator is provided in the drum and a hole is formed in the photosensitive material in a state where the photosensitive material is attached to the drum. However, the holes for fixing the post-processing device such as the printing device to which the sensitive material is attached and the plate-making device are
The intervals and sizes may differ from device to device. Therefore, there is a problem in that the perforator fixed in this way cannot be applied to various post-processing devices. Also,
There is also a problem when performing the following spiral exposure.

In order to speed up the image output, the drum-type image output apparatus uses a multi-beam head 41 in which a plurality of point light sources are arranged in the sub-scanning direction, as shown in FIG. Scan in a spiral. in this case,
As shown in FIG. 7, the output image 53 is inclined with respect to the photosensitive material 50. Accordingly, the holes 51 and 52 punched by the punch provided in the drum 40 are used as they are, and the photosensitive material 5
When 0 is fixed to a printing machine, a plate making device, etc., the image 53 is printed or plate-formed in an inclined state with respect to the paper. For this reason, in the finally obtained printed matter, the image is formed to be inclined with respect to the paper, so that the appearance becomes poor, and
When cutting an unnecessary portion around the paper, the cutting line must match the inclined image line, which makes the cutting work very troublesome.

The present invention has been made to solve the above problems, and an object thereof is to easily and accurately form a reference hole suitable for various post-processing devices. Another object of the present invention is to provide a punching device for an image output device, which is capable of preventing the image from being inclined with respect to a sheet in a finally obtained printed matter in the case of spiral scanning.

In this way, two second reference holes are punched by the second reference hole puncher on the photosensitive material fixed on the mounting table. The two second reference holes are provided on a line forming a predetermined angle with the row of the first reference holes.
Therefore, by appropriately selecting this predetermined angle, it is possible to open the second reference hole which is not inclined with respect to the image output while being inclined with respect to the row of the two first reference holes in the image output device. it can. Then, by mounting the photosensitive material on the post-processing device with reference to the second reference hole, the image does not tilt with respect to the paper.

According to the sensitive material punching device of the third aspect, since the predetermined angle can be changed, it is possible to appropriately deal with the images output at various inclination angles individually. Further, in the sensitive material punching device of the fourth aspect, since the predetermined angle is an intermediate value of the inclination angles of the images of a plurality of patterns that can be output, there is no need to make fine setting changes.
The tilt angle of most output images can be reduced to a negligible extent.

It is very easy to deal with since it only needs to be changed.

By performing this perforating operation on all the color-separated plates of the photosensitive material, the second reference holes 23 and 24 perforated in the respective color-separated plates (sensitive material 20) and the formed image are mutually reciprocated. The positional relationship is the same throughout each color separation plate, and therefore no color misregistration occurs during printing.

Next, an embodiment of the photosensitive material punching device according to the second and third aspects will be described with reference to FIGS. As shown in FIG. 3A, the sensitive material punching device 60 of the present embodiment has a mounting table 6 as shown in FIG.
1 and a puncher 62 detachable from the mounting table 61. A movable lever 69, part of which protrudes from the side surface, is provided below the mounting table 61. Two reference pins 65 and 66 are planted in the lever 69, and the lever 69 is rotatable around the reference pin 65. At the positions corresponding to the reference pins 65 and 66 of the mounting table 61,
Elliptical holes 67 and 68 are provided, respectively. Therefore, the lever 69 can be set to incline at an arbitrary angle within a predetermined range with respect to the upper side. Note that vertical and horizontal squares 611 are drawn on the upper surface of the mounting table 61 for the convenience of confirming the inclination of the rectangular photosensitive material.

The puncher 62 includes a main body 621 to be mounted on one end of the mounting table 61 and a die block 62 rotatable for the main body 621 for punching the photosensitive material 20.
A male die 623 is provided at a predetermined position on the surface of the die block 622 on the mounting table 61 side. The puncher 62 shown in FIG. 3A has two male dies 623, but the puncher 72 shown in FIG. 3B has three male dies 723. In this way, the puncher 62 corresponding to the post-processing device such as the printing machine and the plate making device,
By preparing various types of 72 and appropriately switching and using them, the second reference holes corresponding to various post-processing devices can be easily and accurately punched, as in the above-described embodiment. Therefore, the present embodiment is also an embodiment of the photosensitive material perforation apparatus of claim 1.

As described above, the image output by the spiral scanning by the multi-beam head 41 as shown in FIG. 6 is, as shown in FIG. 7, a straight line connecting the first reference holes 51, 52 punched by the image output device. The image is tilted with respect to.
When the second reference hole is punched in such a sensitive material 50 by the sensitive material punching device of the present embodiment, first, as shown in FIG.
The first reference holes 51 and 52 of 0 are fitted into the two reference pins 65 and 66 of the lever 69, and the photosensitive material 50 is placed on the mounting table 61. Next, the end of the lever 69 protruding from the mounting table 61 is moved so that the sides of the image 53 are parallel to the squares 611 drawn on the surface of the mounting table 61. The die block 6 of the puncher 62 with the sides of the image 53 parallel to the squares 611 drawn on the surface of the mounting table 61.
22 is pushed down, and the second reference holes 55 and 56 are opened in the photosensitive material 50. By mounting the photosensitive material 50 on a printing machine, a plate making apparatus, etc. using the second reference holes 55, 56, one side of the rectangular image 53 is the second reference holes 55, 5 in the post-processing apparatus.
6 rows will be arranged in parallel.

Incidentally, it is desirable to provide a scale 612 on the portion of the mounting table 61 where the lever 69 projects so as to serve as a guide for determining the position of the lever 69. Further, the maximum tilt angle of the lever 69, that is, the length of the oval hole 68 on the right side in FIG. 4, may be set in consideration of the maximum tilt angle θgmax of an output image described later in the image output device.

As described above, in the image output device, the first
Even if images having various inclination angles are formed with respect to the rows of the reference holes 51 and 52, the second reference holes can be punched according to the inclination angles, and the two second reference holes are arranged. Since the rows are parallel to one side of the rectangular image formed on the photosensitive material, the finally obtained image does not tilt with respect to the paper.

Next, an embodiment of the photosensitive material punching device according to the present invention will be described with reference to FIG. In the sensitive material punching device 80 of the present embodiment, the puncher 82 is attachable to and detachable from the mounting table 81 similarly to the sensitive material punching device 60 shown in FIG. 3, but the reference pins 85 and 86 are not movable and are mounted. It is fixed on the table 81. However, the straight line 8 connecting both reference pins 85 and 86
7 is both dies 8 for punching the second reference hole of the puncher 82.
It is set so as to be inclined by an angle θ with respect to a straight line 88 connecting 23. This angle θ is set to an approximately intermediate value of the range of the tilt angle of the image with respect to the row of the first reference holes, which is set by the image output device, and is determined as follows, for example.

When the width in the sub-scanning direction (scan line width) for one main scanning by the multi-beam head of the image output device is L and the peripheral length of the drum is 2.pi.R, the image output by the spiral scanning is The inclination angle θg is θg = arctan {L / (2 · π · R)}. Therefore, if the minimum value of the scan line width that can be set by the image output device is Lmin and the maximum value is Lmax,
The inclination angle θg changes from θgmin = arctan {Lmin / (2 · π · R)} to θgmax = arctan {Lmax / (2 · π · R)}. Sensing material punching device 80 of the present embodiment
Then, the inclination angle θ of the straight line 87 connecting both reference pins 85 and 86
Is the average of the minimum and maximum values θgav = [arctan {Lmax / (2 ・ π ・ R)} + arctan {Lmax / (2
・ Π ・ R)}] / 2. As a result, the inclination angle when the image is output to the post-processing device is reduced for most of the images that are output by being inclined by the spiral scanning.

[0028]

According to the photosensitive material punching device for an image output apparatus of the present invention, the first reference hole to be punched in the image output apparatus is used as a reference, and the printing machine, the printing plate apparatus, etc. Since the second reference holes are punched by the second reference hole puncher set according to the processing apparatus, the reference holes of various post-processing apparatuses can be easily and accurately punched.

Further, in the photosensitive material punching device according to the second aspect,
Since the two second reference holes are formed on the line inclined with respect to the row of the two first reference holes, even if the image is output in an inclined manner due to the spiral scanning in the image output device, the post-processing device Since the image formed in 1 is not inclined with respect to the paper, it has a good appearance, and even when cutting an unnecessary portion around the paper, it can be cut accurately and easily along the frame of the image.

In the photosensitive material punching device according to the third aspect, even if the image formed in the image output device can take various tilt angles with respect to the row of the first reference holes, the tilt angle depends on the tilt angle. Since the second reference hole can be drilled by
The image obtained by the post-processing device does not tilt with respect to the sheet even if the tilt angle of the image in the image output device is changed.

Further, in the photosensitive material perforating apparatus according to the fourth aspect,
Even if the image formed in the image output device can have various inclination angles with respect to the first row of reference holes, the inclination angle of the image with respect to the second row of reference holes can be obtained in the image output device. It is set to almost the middle value of the tilt angle. Therefore, even if the inclination angle of the image in the image output device is changed, the inclination angle of the finally obtained image with respect to the paper is reduced and becomes almost negligible. Therefore, it is not necessary to adjust the drilling position of the second reference punch.
