When the jam detection signal of the mask original plate 12 is input from 6, first, the pressure developing device 41 and the heat fixing device 53 are removed.
The operation of other devices including the exposure device 33 is stopped, and then it is determined whether or not a latent image of the photosensitive recording medium 38 after exposure is stored in the buffer device 40, especially if a latent image is stored. In this state, the latent image on the photosensitive recording medium 38 stored in the buffer device 40 is subjected to pressure development and heat fixing by the pressure developing device 41 and the heat fixing device 53, and then the pressure developing device 41 and the heat fixing device 53 The operation of the fixing device 53 is stopped, and the error display section 71 is activated to display that the mask original 12 has jammed.

Next, the operation of the color image recording apparatus configured as described above when forming a plurality of color images from one set of mask originals will be described.

Now, when forming this color image, first, the monochrome laser printer 2 is used to form the red mask original plate 12R.

This mask original plate 12R has toner, which is a light-shielding image, placed on other parts of the mask original plate 12R so as to harden the microcapsules containing a cyan dye precursor in the microcapsules coated on the photosensitive recording medium 38. .

Then, the mask original 12R is fed from the ADF tray 10 into the apparatus main body 1 by the paper feed roller 11, passes through the mask original transport path 16, and is sent to the alignment device 15 by rollers L7 and 18. Also, this mask original version 1
During the transfer of 2R, the curl of the mask original 12R is corrected by the recurler roller 22. At this time, the gate 25 is placed at the position shown by the solid line in FIG.

Furthermore, after the mask original 12R is conveyed to the vicinity of the exposure position by the roller 20 of the alignment device 15, it is moved to a predetermined position and aligned based on the reading of the alignment mark on the mask original 12R by a sensor (not shown). be done. Immediately before this positioning, the exposure table 39 is placed on the cam 45.
The photosensitive recording medium 38 is lowered to a predetermined position by pressing the fixed roller 46 against one end of the exposure table 39, and the photosensitive recording medium 38 is clamped and fixed between the exposure table 39 and the exposure table 39. After the alignment is completed, the exposure table 39 or the cam 45 further lowers the
It is joined to the glass plate 19 of the alignment device 15, and the mask original 12R and the photosensitive recording medium 38 are brought into close contact.

After that, either the lamp 34 of the exposure device 33 or the let filter 3
At the same time, the exposure device 33 is run in the direction of arrow A in FIG. 1, and the photosensitive recording medium 38 is exposed through the mask original plate 12R by the red tip passed through the red filter 36R. be done. When this exposure is completed, the lamp 34 is turned off and the exposure device 33 is returned in the direction of arrow B in the figure. At this time, the filter unit 36 of the exposure device 33 is moved by a drive source (not shown), and the clean filter 36G is placed oppositely above the lamp 34.

Also, during the return movement of the exposure device 33, the exposure table 3
9 is raised to a predetermined position by the cam 45, and the photosensitive recording medium 38 is separated from the glass plate I9 of the alignment device 15 and the mask original 12R.

At this time, tension is applied to the photosensitive recording medium 38 at the center of the take-up roller for the photosensitive recording medium 38 in the cartridge 37, so when the exposure table 39 is lowered prior to exposure, the exposure table 38 When the length of the photosensitive recording medium 38 corresponding to the amount of descent is pulled out of the cartridge 37 and the exposure stage 39 is raised after exposure, the photosensitive recording medium 38 is rewound into the cartridge 37 and the slack is absorbed. Ru.

Note that even after the exposure using the red mask master plate 12R is completed, the exposure table 39 remains elevated to a predetermined position, and the photosensitive recording medium 38 is pressed against one end of the exposure table 36. It is held in a fixed state relative to the exposure table 39 by a fixed roller 46 .

Next, a green mask original 12G is created by the monochrome laser printer 2, and is fed into the main body of the apparatus 1 through the ADF tray 1O and the paper feed roller 11. When the mask original 12G is conveyed through the curler roller 22 and the mask original transport path 16 to just before the roller 17, the mask original is moved by the rollers 17, 18, 27, 29 and the rollers 20 and 21 of the alignment device 15. It is rotated in the direction of conveyance to the right, and at the same time as the exposed mask original 12R is sent out from the exposure position on the alignment device 15, a new mask original 12G is sent to the exposure position and stopped. At this time, the gate 30 is placed at the position shown by the solid line in FIG.
After passing through 0, the roller 29 is stopped to maintain that state.

The green mask original plate 12G sent to the alignment device 15 is the same as the red mask original plate 12G sent to the alignment device 15.
As in the case of R, after being aligned with the photosensitive recording medium 38, the exposure table 39 is lowered to come into close contact with the photosensitive recording medium 38. In this state, the lamp 34 of the exposure device 33 is turned on, the exposure device 33 is moved, and the mask original plate 1 is exposed to green light that has passed through the green filter 36G.
Exposure is performed via 2G. After the exposure is completed, the exposure table 39 is raised to a predetermined position, the exposure device 33 is moved back, and the filter unit 36 is moved so that the blue filter 36B is placed opposite to the lamp 34.

Next, the blue mask original 12B created by the monochrome laser printer 2 is fed into the apparatus main body 1 in the same way as in the above case, and when it is conveyed to just before the roller 17, the rollers 17, 18, 27 °28 and alignment device 15
The rollers 20 and 21 are rotated in the direction of conveying the mask original to the right, and at the same time, the exposed mask original 12G is sent out from the exposure position on the alignment device 15, and at the same time, the new mask original 12B is sent to the exposure position. and stopped. At this time, one gate 25 is placed at the position shown by the solid line in FIG. 1, and the other gate 30 is placed at the position shown by the broken line in the same figure.
2G is held between the rollers 28 and held in that state by stopping the rollers 28 when its rear end passes through the gate 30.

Then, the blue mask original 12B sent to the alignment device 15 is transferred to the photosensitive recording medium 3 as in the above case.
8 and are brought into close contact. In this state, the mask original 12B is illuminated by blue light passing through the blue filter 36B.
Exposure is performed through the. Through the above operations, a latent image of a desired color image is recorded on the photosensitive recording medium 38.

Thereafter, the exposure table 39 is raised to the initial position by the cam 45, the fixed roller 46 is separated from one end of the exposure table 39, and the fixation of the photosensitive recording medium 38 is released. The photosensitive recording medium 38 is moved in the direction of arrow C from the broken line position and stored in the buffer device 40 at the latent image forming area of the photosensitive recording medium 38 after exposure or before the pressure developing device 4, and the unexposed portion of the photosensitive recording medium 38 is transferred to the cartridge. It is pulled out from inside 37 to a position below exposure table 39 . At this time, the photosensitive recording medium 38 is conveyed by the rotation of the drive roller 43, and when the front end of the latent image reaches the pressure roller 50 of the pressure developing device 41, the conveyance is stopped. Then, in synchronization with the conveyance of the photosensitive recording medium 38, the feeding device 49 feeds the developer from the developer cant 48 or the cassette 47, and the leading edge of the developer cant 48 is placed at the leading edge of the latent image on the photosensitive recording medium 38. When the color developer channel 48 reaches the color developer, the conveyance of the color developer channel 48 is stopped.

In this state, the pressure roller 50 of the pressure development device 41 is rotated by a drive device (not shown), and the photosensitive recording medium 38 or the color developer sheet 48 is superimposed on the photosensitive recording medium 38 or the color developer sheet 48 and transferred while being pressed. As a result, the uncured microcapsules on the photosensitive recording medium 38 are destroyed by pressure, and a color image corresponding to the latent image on the photosensitive recording medium 38 is formed on the developer sheet 48.
developed on top. Also, prior to this development, the exposure table 39
is again lowered to a predetermined position, the fixed roller 46 is pressed against one end of the exposure table 39, and the photosensitive recording medium 38 is clamped and fixed between the exposure table 39 and the fixed roller 46.

Therefore, when the pressure roller 50 of the pressure developing device 41 rotates, the buffer device 40 is moved in the direction of the arrow in FIG.

After development, the color developer sheet 48 is peeled off from the photosensitive recording medium 38 by the separation roller 42 and transferred to the heat fixing device 53.
You will be guided in the direction of In the heat fixing device 53, the color developer sheet 48 is heated by hot air heated by the heater 54 and circulated within the canon 56 by the impeller 55, thereby promoting color development of the color image.

At the same time, the binder polymer (binder resin) for fixing the color developer to the base paper on the color developer sheet 48 is thermally melted and the surface becomes smooth, so that the surface of the color developer sheet 48 has a suitable amount. Provides gloss. Then, the color developer sheet 48 that has undergone the color development and gloss treatment is discharged onto the output sheet discharge tray 62.

During the series of development and color gloss processing described above, the photosensitive recording medium 38 is clamped and fixed between the exposure table 39 and the fixed roller 46. Exposure processing of the latent image of the next color image can be performed at the position.

In other words, when exposing the second color image,
First, the rollers 17, 18, 27, 29 and the rollers 20, 21 of the alignment device 15 are rotated in the direction of conveying the mask original to the left, and the blue mask original 12B at the exposure position is sent out to the left. At the same time, the red mask original 12R held at the position of the roller 29 is sent to the exposure position. At this time, both gates 25 and 30 are placed at the positions shown by solid lines in FIG. Once it has passed, the roller 17 is stopped to maintain that state.

Then, the red mask original plate 12R sent to the alignment device 15 is placed on the photosensitive recording medium 3 as in the above case.
8 and are brought into close contact. In this state, the mask original 12R is exposed to red light passing through the red filter 36R.
Exposure is performed through the.

Next, the rollers 24, 18, 27, 28 and the rollers 20, 21 of the alignment device 15 are rotated in the direction of conveying the mask original to the left, and the red mask original 12R at the exposure position is sent out to the left. At the same time, the green mask original 12G held at the position of the roller 28 is sent to the exposure position. At this time, both gates 25.30
is arranged at the position indicated by the broken line in FIG. It is held in that state by stopping.

Then, the green mask original 12G sent to the alignment device 15 is aligned and brought into close contact with the photosensitive recording medium 38, and in this state, green light passing through the green filter 36G causes the green mask original 12G to pass through the mask original 12G. Exposure is performed.

Further, in almost the same manner as described above, the green mask original plate 12G at the exposure position is sent out to the right, and at the same time, the blue mask original plate 12B held at the position of the roller 17 is sent to the exposure position. It can be done. Then, with this mask original plate 12B in close contact with the photosensitive recording medium 38, blue light passing through the blue filter 36B is used to
Exposure is performed through the mask original 12B. Through the above operations, a color latent image is recorded on the photosensitive recording medium 38, and based on this latent image, the pressure developing device 4
A color image is formed on the color developer sheet 48 by the color developer sheet 48, the heat fixing device 53, and the like.

In this way, three mask original plates 12R and 12G.

By repeatedly performing the exposure operation using 12B, a predetermined number of color images can be continuously output from one set of mask originals 12. After the required number of color images have been output, each mask master plate 12R, 12G, 12
B passes through the rollers 28 or 29 and is discharged onto the mask original discharge tray 26.

Furthermore, if the next mask original 12 is output from the monochrome laser printer 2 while a series of color images are being exposed, the mask original 12 is transferred to the ADF h-ray 10.
After the exposure of the previous set is completed, the sheets are fed into the main body l of the apparatus one by one from the top of the ADF tray 10 by the feed roller 11. Furthermore, when a mask original output from another monochrome laser printer or a previously used mask original is to be used again, it can be fed into the main body 1 of the apparatus by setting it on the ADF tray 1O.

Next, the operation when a jam occurs in the mask original 12 in the image forming process will be described with reference to the flowchart of FIG. 3.

Now, if a jam occurs in the mask original transport path 16 or the mask original storage section 23 while the mask original 12 is being transported to the alignment device 15, the jam is detected by the jam detection sensors 65 and 66, and the CPU 67 detects the jam. A detection signal is output (step St). Based on this detection signal, under the control of the CPU 67, the pressure developing device 41
With the exception of the heat fixing device 53 and the exposure device 33, the operation of other devices including the exposure device 33 is stopped, and a flag in the RAM 69 determines whether or not the latent image of the photosensitive recording medium 38 after exposure is stored in the buffer device 40. (Step 3)
2. S3).

If it is determined that a latent image is stored in the buffer device 40, the pressure developing device 41 and the heat fixing device 5
3, the latent image on the photosensitive recording medium 38 stored in the buffer device 40 is subjected to pressure development and heat fixing, and then the pressure development device 4I and the heat fixing device 53
At the same time, the error display section 71 is activated to display that the mask original 12 has jammed (steps 84 to 36). On the other hand, if it is determined in step s3 that no latent image is stored in the buffer device 40, the operations of the pressure developing device 41 and the heat fixing device 53 are immediately stopped, and the error display section 71 is displayed. The occurrence of a jam in the mask original 12 is displayed (step S6).

Therefore, in the image recording apparatus of this embodiment, when a jam is detected, the apparatus is not stopped with the latent image of the exposed photosensitive recording medium 38 still stored in the buffer device 40; When setting the apparatus again, the exposed photosensitive recording medium 38 stored in the buffer device 40
There is no need to wind up and waste the latent image portion of the image, making it easier to set up the device and reducing the running cost of the device.

Note that the present invention is not limited to the configuration of each of the embodiments described above. For example, a detection sensor may be provided near the alignment device 15 to prevent abnormal conveyance such as misalignment of the mask original with respect to the alignment device 15. Even when this occurs, the same operation control as in the embodiment described above may be performed, regardless of whether the pressure developing device 41 and the heat fixing device 53 are stopped with a delay.
The configuration of each part may be arbitrarily changed without departing from the spirit of the present invention, such as configuring the error display section 71 to display an operation indication at the same time as the detection means such as the jam detection sensor 65, 66 is detected. It is also possible to make it concrete.

[Effects of the Invention] As explained above, this invention, when abnormal conveyance of a mask original is detected, if a latent image of a photosensitive recording medium after exposure is stored in the buffer means, After pressure development and heat fixing are performed on the stored latent image on the photosensitive recording medium, the entire device is activated or stopped, so the device may not be activated upon detection of abnormal conveyance of the mask original. To facilitate the setting work of a device without winding up and wastefully discarding the latent image portion of a photosensitive recording medium stored in a buffer means after exposure when setting the device again after being stopped. At the same time,
This has the excellent effect of reducing the running cost of the device.
