Next, the operation of reading the information of the barcode 5 of one set of mask originals 4 (R, G, B) will be explained with reference to the flowchart shown in FIG. In this embodiment, when the reading device 6 reads the information of the identification mark 5 of the mask original 4, a normal rotation signal is output to the roller 28, and the roller 28 transfers the mask original 4 to the exposure device 35.
When the information on the identification mark 5 cannot be read by the reading device 6, a reverse rotation signal is output to the roller 28, and the mask original 4 is returned to the reading device 6 by the roller 28. The reading operation is repeated within a predetermined number of times, and when the reading is successful, a normal rotation signal is output to the roller 28 to transfer the mask original 4 to the exposure device 35.
On the other hand, when the reading operation exceeds the predetermined number of times without being able to be read, a normal rotation signal is output to the roller 28 and the mask original 4 is discharged to the tray 1.
I am trying to drain it at 1.

First, when the mask original plate 4 (R, G, B) is set in the ADF 24 (step 5-1), the recurler roller 28
The mask original plate 4R is then rotated forward and taken into the color image recording device 3 (step 5-2).

Mask original plate 4R taken into color image recording device 3
The information of the barcode 5 is read by the optical device 6 (step 5-3). After the information on the barcode 5 is read, the reading counter is transferred to the mask original 4R or the optical device 6.
Count passing once (Step 5-4)
. Next, the number of times N of reading the mask original plate 4R (here, N=
1) and the reading count setting value A are compared by the comparison means (step 5-5).

That is, the read count setting value A of the mask original plate 4 (R, G, B) is compared with the reread count N of the mask original plate 4 (RXG, B), and if N≦A, the process starts from step S-5. Proceeding to step S-6, it is determined whether or not the information on the barcode 5 has been read.If it is determined that the information on the barcode 5 has been read, a normal rotation signal is output to the recurler roller 28. The recurler roller 28 is rotated in the forward direction (step S-6a), and the mask original 4R is thereby transported to the exposure device 35 and subjected to exposure processing (step S-6a).
-7) and is ejected to the ejection tray 11 (step 5-8).
). However, in step S-6, if it is determined that the information of the barcode 5 cannot be read, a reverse rotation signal is output to the recurler roller 28, so that the recurler roller 28 moves to reverse operation (step S-11). The mask original 4R is returned to the ADF 24 side by rotating the recurler roller 28 in the reverse direction. Here, recurrer roller 2
8 is a mask original return confirmation device 44 (Fig. 1).
The mask original return confirmation device 44 is configured to confirm the leading edge of the mask original 4R moving toward the ADF 24 and output a confirmation signal to the recurler roller 28. The recurler roller 28, which has received the confirmation signal from the mask original return confirmation device 44, then shifts to normal rotation operation (step 5-2), and the mask original 4R is detected by the optical device 6 again. In this way, the operations of steps S-2 to S-6, 5-11 and 5-12 are repeated. By the way, after recording the counter, the number of readings N of the counter is compared with the set value A of readings (step 5-5), but depending on the comparison, the relationship N≦A is established, and the information of barcode 5 can be read. If so, proceed to step S.
-6 to step S-8, or if the information of barcode 5 cannot be read even if N≦A, step l-6, 5-11, 5-12, S- Repeat the operations from 2 to S-6. However, barcode 5
When the reading operation exceeds a predetermined number of times without being able to read the information of -9) The mask master plate 4R passes through the exposure device 35 (FIG. 1) without being exposed and is discharged onto the discharge tray 11 (step S-10).

Thereafter, the same operation as the mask original 4R is performed in the order of the mask originals 4G and 4B. In addition, 3 mask original plates 4 CR
Mask original plate 4 of any one of XG, B) (R,
If the information on the barcodes 5 (G, B) cannot be read, all three mask originals 4 (R, GXB) will be discharged onto the discharge tray 11. Since the recurler roller 28 in the image recording apparatus 1 of this embodiment can rotate forward (arrow X in FIG. 1) and reverse (arrow W), the mask original 4 (
R, GSB) can be returned to the optical device 6 to read the information on the barcode 5 again. In addition, to explain the number of readings N and the number of readings setting value A, the number of readings N
indicates the number of times each mask original 4 (RSG, B) is returned to the optical device 6 by reversing the recurler roller 28. Also, read count setting value A
is the maximum number of readings required to determine whether the barcode 5 has been read successfully. That is, the information of the barcode 5 is read repeatedly up to the maximum number of times A to reduce the number of erroneous determinations. In addition, by setting the reading count setting value A arbitrarily, the information of the barcode 5 can be reread up to a predetermined number of times (reading count setting value A).
Mask original plate 4 (R, G, B) is transferred to color image recording device 1
Changes in speed when feeding inside, and mask original plate 4
Even if (R, G, B) is curled or has some creases, the information in the barcode 5 can be read.

Further, the reading count setting value A can be arbitrarily changed depending on the type of printing machine.

Second Embodiment The image recording apparatus 1 also includes three mask original plates 4 (R,
If the information on the barcode 5 of any two of the mask master plates 4 among G and B) was read by the optical device 6, but the information of the barcode 5 of the remaining mask master plate 4 could not be read, the information could not be read. It is determined which color the mask original plate 4 (RXG, B) was created for, and a normal rotation signal is output to the leak curler roller 28. Three mask original plates 4 (
R, G, B) can also be transported to the exposure device 35 and subjected to exposure processing. Since the mask master plates 4 (R, G, B) used for exposure processing are a set of three, this can be done by reading the information on the barcode 5 of any two of the mask master plates 4. It is possible to secondarily determine which color the unreadable mask original 4 was created to correspond to.

Therefore, any two mask original plates 4 (RlGXB
) If you can read the information in the barcode 5, you can perform image processing.

〔Effect of the invention〕

Since the image recording device according to the first aspect is configured as described above, it is possible to improve the ability to read information on the identification mark by returning the mask original to the reading device and reading the identification mark again. It is possible to eliminate the waste of the original version.

In addition, in the image recording apparatus according to claim 2, since the information on the identification marks of any two of the three mass originals can be read, it is possible to determine which color the one mask original that cannot be read corresponds to. It can be determined whether the original mask was created using the original mask, and there is no need to waste the original mask being ejected to the ejection tray.
