[0028]
The image recording apparatus 10 according to the present embodiment and the package 12 loaded therein are basically configured as described above. Next, for the processing method of identification information using these, This will be described based on the processing flowchart shown in FIG.
[0029]
As a preparatory stage, as shown in FIG. 1, after pulling out one of the mounting tables 36, 38, 40 (in this case, the mounting table 36), the first and second attached to the light shielding bag 14. The packaging body 12 is stored on the mounting table 36 with the barcode labels 26A and 26B (see FIG. 3) of In this case, the first barcode label 26 </ b> A is in a state that can be detected from the outside through the opening 41 formed in the mounting table 36.
[0030]
Next, after the packaging body 12 is stored on the mounting table 36, the end portion of one fin portion 18b of the light shielding bag 14 is cut off. In addition, since the light shielding bag 14 is stored in the state pressed against the inner peripheral wall of the mounting table 36, the internal film F is maintained in a light-tight state. The other fin portion 18 a is set so as to protrude from the mounting table 36 to the front of the image recording apparatus 10.
[0031]
After the packaging body 12 is stored on the mounting table 36 as described above, the mounting table 36 is loaded into the image recording apparatus 10 (step S1). When the control unit 72 confirms that the mounting table 36 is loaded in the image recording apparatus 10 based on the mounting table detection signal from the mounting table detection unit 76 (step S2), the control table 72 uses the barcode reader 43 to place the mounting table. The bar code 22 recorded on the first bar code label 26A attached to the light shielding bag 14 of the package 12 stored in 36 is read (step S3).
[0032]
On the other hand, the operator loads the mounting table 36 on which the package 12 is placed in the image recording apparatus 10, and then pulls out the fin portion 18 a of the light shielding bag 14 exposed to the outside of the image recording apparatus 10. At this time, the film F is left in the image recording apparatus 10 while being held on the application paper 16 and the mounting table 36.
[0033]
By the way, the timing of pulling out the light shielding bag 14 is preferably after the barcode 22 of the first barcode label 26A is normally read by the barcode reader 43. However, depending on the operator, the package 12 In some cases, extraction is started immediately after the mounting table 36 on which is mounted is loaded into the image recording apparatus 10.
[0034]
In such a case, reading of the barcode 22 of the first barcode label 26A is not normally performed, and there is a possibility that appropriate processing thereafter stops.
[0035]
Therefore, in the present embodiment, the second barcode label 26B is attached to the light shielding bag 14 in addition to the first barcode label 26A. Specifically, the first and second barcode labels 26A and 26B are attached to the light shielding bag 14 along the direction in which the light shielding bag 14 is pulled out (indicated by an arrow A in FIG. 3). ing. Thereby, in the process of pulling out the light shielding bag 14, the first barcode label 26 </ b> A cannot be seen from the opening 37, but then the second barcode label 26 </ b> B arrives at the opening 37 and passes through the opening 37. The second barcode label 26B is faced.
[0036]
The first and second barcode labels 26A and 26B have the extending direction of each bar 22a constituting the barcode 22 printed on the barcode labels 26A and 26B as the drawing direction of the light shielding bag 14. It is stuck on the light shielding bag 14 so as to be substantially parallel.
[0037]
Further, the arrangement interval d of the first and second barcode labels 26A and 26B is defined as T from the time when the barcode reader 43 detects a reading error until it can be read again, and the pulling speed of the light shielding bag 14 is set. When V is set, it is set to T × V or more. That is, a certain amount of time is required for reading the barcode 22 by the barcode reader 43, and the second barcode label 26B arrives at the opening 37 after the above time (T × V) has elapsed. Set to.
[0038]
Returning to the description of FIG. 6, the controller 72 first checks the barcode data obtained from the barcode 22 in the first barcode label 26A read by the barcode reader 43 (step S4). As a barcode data check method, for example, a known method using a check digit system is known.
[0039]
As a result of checking the barcode data, if it is determined that the reading has been normally performed, the identification information related to the barcode data is stored in the data storage unit 80 together with the information for specifying the mounting table 36 (step S5). .
[0040]
If it is determined that the reading is abnormal as a result of checking the barcode data, the control unit 72 now checks the barcode data obtained from the barcode 22 in the second barcode label read by the barcode reader 43. (Step S6).
[0041]
As a result of checking the barcode data, if it is determined that the reading has been normally performed, the identification information related to the barcode data is stored in the data storage unit 80 together with the information for specifying the mounting table 36 (step S5). .
[0042]
If it is determined in step S6 that the barcode data has been read and it is determined that there is a reading abnormality, the control unit 72 displays that there is a reading abnormality in step S7 and stops the subsequent processing. To do.
[0043]
At the stage where the processing in step S5 is completed, the control unit 72 confirms that the light shielding bag 14 is extracted based on the light shielding bag detection signal from the light shielding bag detection unit 78 in the next step S8.
[0044]
When it is confirmed that the barcode data has been input and the light shielding bag 14 has been removed as described above, the control unit 72 performs processing for recording the radiation image information by sheeting the desired film F. To start.
[0045]
Specifically, the control unit 72 uses the film F identification information stored in the data storage unit 80 and the information on the mounting tables 36, 38, and 40 in which the film F is stored to obtain a desired film. The mounting bases 36, 38 and 40 in which F is stored are selected (step S9).
[0046]
When the mounting tables 36, 38, 40 are selected, the control unit 72 biases the sheet mechanisms 48, 50, 52 and the transport mechanism 74, and transports the desired film F to the image recording unit 54. (Step S10).
[0047]
The film F conveyed to the image recording unit 54 is nipped and conveyed in the sub-scanning direction by the roller 56 and the plate 58, and the laser beam L modulated according to the radiation image information from the image recording unit 54 is in the main scanning direction. The radiation image as a latent image is two-dimensionally recorded on the film F (step S11).
[0048]
The film F on which the radiation image is recorded is heated and developed by the heat applied from the plate heaters 64a to 64c while being transported by the roller 62 and the drum 66 in the heat developing unit 60, and the latent image is converted into a visible image. (Step S12). The film F on which the visible image is recorded is cooled in the cooling unit 68 (step S13) and then discharged to the discharge unit 70 (step S14).
[0049]
Thus, in the present embodiment, since the first and second barcode labels 26A and 26B are attached to the light shielding bag 14, the identification information can be read from the first barcode label 26A. Even if it is defective, the identification information can be read from the second barcode label 26B along with the movement and removal of the light shielding bag 14, and the recognition rate of the identification information can be improved.
[0050]
In particular, in the present embodiment, since the first and second barcode labels 26A and 26B are attached along the movement removal direction of the light shielding bag 14, the first and second barcode reader 43 uses the first and second barcode labels. The identification information can be easily read from the bar code labels 26A and 26B.
[0051]
And when sticking the 1st and 2nd barcode label 26A and 26B to shading bag 14, the extension direction of bar 22a which constitutes barcode 22 printed on these barcode labels 26A and 26B, The reading accuracy of the bar code 22 by the bar code reader 43 can be improved because it is substantially parallel to the drawing direction of the light shielding bag 14.
[0052]
In addition, the arrangement interval d of the first and second barcode labels 26A and 26B is set to T, the time from when the barcode reader 43 detects a reading error until it can be read again, and the drawing speed of the light shielding bag 14 Since V is set to T × V or more, the recognition rate of identification information can be further improved.
[0053]
Further, the bar code reader 43 reads all the bar codes 22 printed on the first and second bar code labels 26A and 26B, and among them, normally read bar code data is used as identification information in the data storage unit 80. Therefore, even if the light shielding bag 14 is quickly pulled out, it is possible to reliably read the barcode on the second barcode label 26B.
[0054]
Next, other reading methods (first and second modified examples) will be described with reference to FIGS.
[0055]
First, in the first modification, for example, the barcode 22 printed on the first barcode label 26A is read in step S101 in FIG. 7, and the barcode data is checked in the next step S102. If the reading result is normal, the barcode data is stored in the data storage unit 80 as identification information in the next step S103.
[0056]
On the other hand, if the reading result is abnormal, in step S104, the barcode 22 printed on the second barcode label 26B is read, and the barcode data is checked in the next step S105. If the reading result is normal, the barcode data is stored in the data storage unit 80 as identification information in the next step S106. If it is determined in step S105 that the reading result is abnormal, in step S107, the display unit 42 displays that there is a reading abnormality.
[0057]
In this first modification, it is necessary to secure a certain amount of time until the barcode is read for the second barcode label 26B, but it is possible to sufficiently cope with the speed at which a person pulls out.
[0058]
Next, a second modification will be described. First, in step S201 in FIG. 8, for example, the barcode 22 printed on the first barcode label 26A is read, and in the next step S202, the barcode data is read. The data is stored in the data storage unit 80 as first data.
[0059]
Next, in step S203, this time, the barcode printed on the second barcode label 26B is read, and in the next step S204, the barcode data is stored in the data storage unit 80 as second data.
[0060]
Then, in the next step S205, the first data and the second data are compared. If they are the same, in the next step S206, they are stored in the data storage unit 80 as identification information for the first time.
[0061]
If it is determined in step S205 that the comparison results are not the same, in step S207, the display unit 42 displays that there is a reading abnormality.
[0062]
In the above-described embodiment, the first and second barcode labels 26 and 28 are attached to the light shielding bag. However, barcode data indicating identification information may be printed on the light shielding bag. Good. In place of the first and second barcode labels 26 and 28, first and second magnetic labels holding identification information, first and second IC (Integrated Circuit) chips, etc. are attached to a light shielding bag. You may make it read the identification information hold | maintained at these.
[0063]
Moreover, although the case where two barcode labels 26A and 26B were stuck was shown in the above-mentioned example, you may make it stick three or more barcode labels.
[0064]
