Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mask original created based on color image information for exposing a photosensitive recording medium.

[Conventional technology]

Conventionally, the following image forming methods are known.

First, images obtained by extracting red (R), green (G), and blue (B) components of a color original image are formed in black, and three types of R and GSB mask originals are created.

That is, to explain with reference to FIG. 3, the mask original output from the laser printer 101 is fed to a paper discharge tray 127, and further fed to an insertion opening 126 in the apparatus main body 120 by a guide member 128.

First, when a red mask original is inserted, the mask original is conveyed downward and reaches the left end of the endless belt 102 stretched in the horizontal direction. This endless belt 102
is made of a transparent material and charged by a device not shown. This mask original is conveyed by the rotation of the endless belt 102 while being attached to the endless heald 102 by electrostatic force. When the mask original reaches a predetermined exposure position, the endless belt 102 stops rotating.

A photosensitive recording medium 106 pulled out from a cartridge 104 is stretched under the endless bell l-102. Then, exposure is performed while this photosensitive recording medium 106 and the transported red mask original face each other. A lamp 108 as a light source for exposure is provided above the endless belt 102, and below the lamp 108, three filters of red, green, and blue are held to selectively cover the lamp 108. First, the red filter 110R covers the lamp 108, and then the endless belt 102 is moved from the left end to the right end. The light from this lamp 108 is selected to have only red light by the light 110R, and then reaches the mask original via the transparent endless belt 102.

This light passes through the sheet portion, which is the base material of the mask original, but is blocked by the black image portion. Therefore, the exposed surface of the photosensitive recording medium 106 is exposed to red light according to the image on the mask original, and a red latent image is formed. After the above processing is completed, the endless belt 102 rotates and sends out the red mask original to the right. The sent-out mask original is conveyed upward through the right path. This route branches into two at a position indicated by the reference numeral 114, and each branch destination is a first and a second branch 116a, 11
It leads to 6b. Then, the red mask original is branched upward by a gate 118 provided at the branch portion, and is stored in the first buffer 116a.

At the same time as this red mask original is evacuated, a green mask original is inserted through the insertion opening 126.

Then, it is conveyed through the same route as the previous time and reaches the exposure position. Note that the photosensitive recording medium 106 is not transported during this time. When the green mask original faces the photosensitive recording medium 106, the lamp 108 moves from the left end to the right end of the endless belt 102 with its lower side covered by the green filter 110G, and exposure with green light is performed. This green mask original is conveyed to the right by the rotation of the endless belt 102, branched downward by a gate 118 at a branching point, and is stored in a second buffer 116b. At the same time, a blue mask original is transported and exposed to blue light.

By the above three exposures, red, green, and blue latent images are superimposed on the same surface of the photosensitive recording medium 106. This photosensitive recording medium 106 is conveyed to the developing section, and the photosensitive recording medium 106 newly drawn out by the cartridge 104 comes to a position facing the endless belt 102.

In this way, color latent images are formed on the photosensitive recording medium from a set of red, green, and blue mask masters, but in order to form multiple latent images of the same color image, first the laser printer The desired number of color images is printed as a bar code outside the image forming area of the original mask. In addition, the mask originals 110R, ll0G, and ll0B output from the laser printer 101 are stored in the apparatus main body 120.
It is necessary to indicate that the image is for red, green, or blue in insertion 0126, and a bar code indicating this is printed outside the image forming area.

The barcode printed on the mask original plate is read by an optical reader disposed in the mask original transport path, and the mask original plate is looped through the apparatus main body 120 in the order of red, green, and blue. While circulating, latent images of a desired number of color images are formed on the photosensitive recording medium.

In addition, when outputting a desired color image from the image recording device by reusing the used mask master, the used mask master discharged to the discharge tray (not shown) attached to the main body 120 of the Mask original plate 110R, ll0G, l
10B is taken out and inserted into the insertion port 126 of the device main body 120.

Even when a mask original output from another laser printer is used again to output a desired color image, this mask original is inserted into the insertion slot 126.

[Problem to be solved by the invention]

However, in the mask master plates of such conventional image recording devices, the types for red, green, and blue are only printed as barcodes outside the image forming area, so the operator cannot Even looking at the barcode, it was difficult to tell whether this original mask was for red, green, or blue.

Here, for the mask original plate that has been used twice or for the mask original plate output from another laser printer, the operator should set up a set of mask original plates for red, green, and blue, and use the machine in the order of red, green, and blue. Insertion port 12 of main body 120
It is necessary to insert it into 6. However, the only thing that tells the worker whether the original mask is for red, green, or blue is the barcode printed on it, so the worker must have one set of red, green, and blue mask originals. It was difficult to insert the red, green, and blue brackets into the insertion slot 126 in this order.

Therefore, the present invention provides a mask original plate for an image recording device that is provided with an information carrying section that contains the same information as a barcode printed on the mask original plate and that transmits this information when visually recognized by an operator. purpose.

[Means to solve the problem]

In order to solve such problems, in the present invention,
In a mask master plate for an image recording device in which a barcode is provided outside the image forming area, an information carrying part is provided outside the image forming area that has the same information as the barcode and transmits this information by visual recognition. That is.

[Effect]

When the mask originals that have been used once are used again to output an image using the image recording apparatus, it is necessary to take out a set of mask originals from among the mask originals discharged to the paper discharge tray. Furthermore, the set of mask originals must be set so that they are fed to the image recording device in an orderly manner. Since the type of mask originals can be determined at a glance by the information carrier, a set of mask originals can be easily taken out and set in accordance with the above order.

The photosensitive recording medium 50 is, for example, disclosed in Japanese Patent Application Laid-Open No. 62-14304.
The main material is a photocurable resin using a polymerization initiator known from Publication No. 4, and the photocurable resin is cured by light of red, green, and blue wavelengths, and cyan, magenta, and yellow. Microcapsules containing each of the dye precursors are coated on a base sheet. The photosensitive recording medium 50 is housed in a cartridge 51 so as not to be exposed to light. The photosensitive recording medium 50 is routed from inside the cartridge 51, passing between the glass plate 34 and the exposure table 52, passing through a buffer 55, a separation roller 64, a pressure developing device 70, and a drive roller 57, and then reaching the take-up roller 54. . The exposure table 52 is lowered by a cam 53, and the mask original 15 conveyed onto the glass plate 34 is placed on the exposure table 52.
and the photosensitive recording medium 50 are brought into close contact with each other. The fixed roller 56 is pressed against the left end of the exposure table 52 when the exposure table 52 is lowered to a predetermined position, and is arranged so as to fix the photosensitive recording medium 50 to the exposure table 52 during exposure of the mask original 15. has been done.

The color developer sheet 60 is, for example, disclosed in Japanese Patent Application Laid-Open No. 58-88739.
It is constructed by applying the color developer shown in the above publication onto a base paper, and is set in a cassette 61 with the developer coated side facing downward. At the top of the cassette 61,
Suction cup 6 for feeding the color developer sheet 60 one by one

The pressure developing device 70 is composed of a photosensitive recording medium 50 on which a latent image is formed by exposure, and a pair of pressure rollers 71 for overlapping a color developer sheet 60 and developing it under pressure.

The heat fixing device 80 is constructed between a casing 83 containing a heater 81 and an impeller 82 in the upper part, rubber rollers 84 and 85° 86 for conveying the color developer sheet 60 in the lower part, and rollers 87 and 88. A paper discharge tray 63 is attached to the outside of the heat fixing device 80, which is composed of a knit dress belt 89.

In the apparatus configured as described above, the operation of obtaining a plurality of color images from one set of mask originals will be briefly explained.

First, the monochrome laser printer 1 creates a red mask original 15R. This mask original version 1.5 R
is a mask original plate in which toner, which is a light-shielding image, is placed on other parts of the microcapsules coated on the photosensitive recording medium 50 in order to harden the microcapsules containing a cyan dye precursor. At this time, a first barcode 92a indicating the red color to be exposed, an alphabet (R) 94a, and a second barcode 93a indicating the number of output sheets are printed on the mask master plate 15R by the laser printer 1.
and Arabic numerals 95a are printed.

Mask original plate 1 output from monochrome laser printer 1
5R is delivered to the ADF tray 12 and fed into the color image recording apparatus 20 by the ADF paper feed roller 13. Mask original plate 15R fed into color image recording device 20
passes through the mask original transport path 21, but when the mask original 15R is transported to the mask original transport path 21, the first . The information written in the second barcodes 92a and 93a (for example, the color to be exposed and the desired number of output color images) is read and output as a signal to the control section of the color image recording device 20.

Next, the mask original 1.5R is sent to the alignment device 31 by the roller pair 24.22, and on the way, the curl of the mask original 15R is corrected by the recurler roller 99.

At this time, the gate 28 is at the position indicated by the solid line.

Next, the alignment device 31 transports the mask original 15R to the appropriate exposure position by the roller pair 32, and then uses a drive source (not shown) to read the alignment mark 97 printed on the mask original 15R with a sensor, and then Move 15R to the specified position.

Immediately before alignment, the exposure table 52 is lowered to a predetermined position by a cam 53, and a fixed roller 5 is placed on the left end of the exposure table 52.

When the exposure table 52 comes into close contact with the alignment device 31, the lamp 42
is turned on, and the exposure device 41 performs scanning exposure in the direction of arrow A in order to expose the photosensitive recording medium 50 with red light via the red filter 44R and the mask original 15R. When the exposure is completed, the lamp 42 is turned off and the exposure device 4 is turned off.
1 moves back in the direction of arrow B. At this time, the filter unit 44 of the exposure device 41 is moved by a drive source (not shown), and the green filter 44G is located in the information of the lamp 42.

While the exposure device 41 moves backward, the exposure table 52 is raised by the rotation of the cam 53, and the photosensitive recording medium 50 is separated from the alignment device 31 and the mask original 15R. At this time, pack tension is applied to the photosensitive recording medium 50 at the center of rotation of the roll of the photosensitive recording medium 50 in the cartridge 51, and when the exposure table 52 is lowered, the tension corresponds to the amount by which the exposure table 52 is lowered. The length of the photosensitive recording medium 50 is pulled out from the storage cartridge 51, and when the exposure table 52 is raised after exposure, the photosensitive recording medium 50 is rewound in a direction to take up the slack.

Even after the exposure of the red mask original 15R is completed, the exposure table 52 only rises to a predetermined position, and the photosensitive recording medium 50 is moved to the exposure table by a fixed roller 56 pressed against the left end of the exposure table 52. It remains fixed at 52.

Next, the green mask original 15G created by the monochrome laser printer 1 is placed in the ADF tray 12,
The first . The second barcodes 92b and 93b are similarly read by the optical reader 98. When the mask original plate 15G comes just before the roller pair 24, the roller pair 22, 24°25
．． 27. The roller pairs 32 and 33 of the alignment device 31 are rotated in the direction of conveying the mask original 15R to the right,
At the same time as the mask original 15R is sent out from the alignment device 31, the mask original 15G is transported to the exposure position and stopped. At this time, the gates 28 and 29 are located at the positions indicated by solid lines, and the exposed mask original 15R is sandwiched between the pair of rollers 27, and with its rear end passing through the gate 29, the rotation of the pair of rollers 27 is stopped. It is maintained by this.

The mask original 15G guided by the alignment device 31 is aligned with the photosensitive recording medium 50 in the same manner as the mask original 15R, and then the exposure table 52 is lowered to align the mask original 15G with the photosensitive recording medium 50. Being brought into close contact. after that,
The lamp 42 is turned on and exposure to green light is performed via the green filter 44G. After the exposure is completed, the exposure table 52 is raised to a predetermined position. The exposure device 41 is moved back to the original position, and the filter unit 44 is moved so that the blue filter 44B is positioned above the lamp 42.

Next, the blue mask original 15B created by the monochrome laser printer 1 is similarly fed to the color image recording device 20, and the first . The second barcode 92C193c is similarly read by the optical reader 98. With the mask original 15B conveyed just before the roller pair 24, the roller pairs 24, 22, 25 .
26 and the pair of rollers 32 and 33 of the alignment device 31 are rotated in the direction of conveying the mask original 15G to the right,
The mask original 15G is sent out from the alignment device 31, and the mask original 15B is conveyed to the exposure position and stopped. At this time, the gate 28 is located at the position shown by the solid line, and the gate 29 is located at the position shown by the broken line. It is maintained by stopping the rotation of.

The mask original 15B guided by the alignment device 31 is brought into close contact with the photosensitive recording medium 50 by the same operation, and the photosensitive recording medium 50 is exposed to blue light through the mask original 15B.

Through the above operations, a latent image of a desired color image is recorded on the photosensitive recording medium 50.

Next, the exposure table 52 is raised to the initial position, the fixed roller 56 and the left end of the exposure table 52 are separated from each other, and the buffer 55 is moved in the direction of the arrow E to remove the unexposed portions of the photosensitive recording medium 50. is pulled out from inside the cartridge 51 below the exposure table 52. Drive roller 57
The photosensitive recording medium 50 is conveyed and stopped when the leading edge of the latent image reaches the pressure roller 71 of the pressure developing device 70.

In synchronization with the movement of the photosensitive recording medium 50, the developer sheet 60 is fed out from the cassette 61 by a suction cup 62 until the tip of the developer sheet 60 corresponds to the tip of the latent image on the photosensitive recording medium 50. After being transported, it stops.

Next, the pressure developing device 70 is driven by a drive device (not shown).
The pressure roller 71 is pressed while being rotated in the direction of the arrow. At this time, by lowering the exposure table 52 to a predetermined position again, the fixed roller 56 is pressed against the left end of the exposure table 52, and the photosensitive recording medium 50 is fixed to the exposure table 52. The photosensitive recording medium 50 is conveyed under pressure while being overlapped with the color developer 60, and the photosensitive recording medium 50
The uncured micro-force pulls on the top are destroyed by pressure, and a color image corresponding to the latent image on the photosensitive recording medium 50 is developed on the developer sheet 60.

By rotating the pressure roller 71 of the pressure developing device 70 in the direction of the arrow, the buffer 55 is moved in the direction of the arrow F. The color developer sheet 60 is peeled off from the photosensitive recording medium 50 by a separation roller 64 and guided toward a heat fixing device 80 .

In the heat fixing device 80, the color developer sheet 60 is heated by a heater 81 and heated by air circulating in a casing 83 by an impeller 82, thereby promoting color development of a color image. At the same time, the pietan polymer (binder resin) for fixing the color developer medium to the base paper of the color developer sheet 60 is thermally melted, and the surface becomes smooth and the surface of the color developer sheet 60 has a moderate gloss. can get. The color developer sheet 60 that has been subjected to color development and gloss treatment is discharged to a paper discharge tray 63.

During the above-described series of development and coloring/glossy processing, the photosensitive recording medium 50 is held and fixed between the exposure table 52 and the fixed roller 56. Therefore, while the development processing for one screen is being performed, the next exposure point is It is possible to perform exposure processing on the latent image of a color image.

When exposing the second color image, first, the mask original 15B at the exposure position is sent to the left, and the mask original 15R held at the position of the roller pair 27 is sent to the alignment device 31 by the rollers. vs. 24, 22, 25

If you want to use 15B again to output a color image,
Among the mask originals discharged to the paper discharge tray 30 by the color image recording device 20, red, green, and blue mask originals 15R, 1 having the same set mark 96 are selected.
Take out 5G and 15B as a set. This set of mask original plates 15R, 15G, and 15B must be set on the ADF tray 12 so that they are fed into the apparatus main body 20 in the order of red, green, and blue.
The red, green, and blue types of R, 15G, and 15B are the alphabets R and G.

Since the number B is printed, the operator can easily understand the type and set it according to the order. In this way, the mask originals 15R, 15 are placed on the ADF tray 12.
When G and 15B are set, the same number of color developer sheets 60 on which color images are formed as described above are discharged to the paper discharge tray 63. Also, when reusing a mask original output from another laser printer to output a desired color image, the operator must use the mask original 15R,
The alphabets R, G printed on 15G and 15B,
If you look at B, you can easily see the type and set it according to the order. Note that when it is desired to output a different number of color images from the previous one, the number is inputted into the control section of the color image recording apparatus. When the desired number of sheets is input to the control section, the desired number of color developer 60 is discharged to the paper discharge tray, regardless of the number of alphabets printed on the mask originals 15R, 15G, and 15B.

〔Effect of the invention〕

As explained above, according to the present invention, since an information carrying part is provided outside the image forming area of the mask original plate and the information is the same as a barcode and the information is transmitted by visual recognition, the mask original plate used once can be used. In order to use the image forming apparatus again to output an image, it is necessary to take out a set of mask originals from the paper output tray, but the information carrying section makes it easy to identify the set of mask originals and to identify the set of mask originals in order. It can be set in the image forming apparatus accordingly. In addition, even when outputting a desired color image by reusing mask masters output from another mask master production device, the information carrying section allows one set of mask masters to be easily identified, and image formation is performed according to the order. It can be set in the device.
