Abstract

PROBLEM TO BE SOLVED: To record a picture in the picture recording medium of optimum output size corresponding to read size by previously designating and storing the output size corresponding to the read size and deciding the output size corresponding to the read size. SOLUTION: A corresponding table showing the relation of read size and output size is previously stored in a storage means. The corresponding table is decided as the output size 3 against the read size D, for example. When a cassette is then charged (S1), a CPU detects the read size from the size of the cassette (S2). When the read size is detected, the CPU refers to the corresponding table (S3). When the read size is decided, the CPU decides the output size corresponding to the read size detected from the corresponding table (S4). Thus, a picture can be recorded in a picture recording medium of the optimum output size.

Next, the detailed operation of the present invention will be described. FIG. 4 shows a display example of the display unit of the display / operation unit 7. In the figure, 700 is a reservation information list, 710
Denotes an image display unit, and 720 denotes a reading registration list. Here, reading registration refers to associating the order of registration with the order of display. The reservation information list 700 displays a list of data to be read. Then, the information for performing the image reading is stored in the storage means. The reservation information list 700 includes a touch panel 71 (see FIG. 2). The numbers in the figure represent the number of characters that can be used.

First, a plurality of types of cassettes 9 are mounted on the cassette stacker unit 3. At this time, the main CPU 60 remembers the slot number to be mounted. Then, the operator mounts the cassette 9 storing the image in an arbitrary slot of the cassette stacker unit 3. At this time, the size and type of the mounted cassette are read by the CPU 60 from the identification seal 911 (see FIG. 1) formed on the surface of the cassette.

When the operator sequentially mounts the cassette 9 in an arbitrary slot, the CPU 60 reads information on which slot the cassette 9 is mounted in, information on the mounting order, and the size of the mounted cassette 9. . These pieces of information are stored in the storage unit.

Next, the CPU 60 performs a reservation selection operation. This reservation selection operation is performed by the operator touching a designated data area from the reservation information list 700. A number “1” indicating that the first touch has been made is displayed on the number display portion 701 corresponding to the name portion that was touched first. Thereby, the CPU 60 acquires the information selected for the reservation and stores it in the storage means.

When the cassette input operation and the reservation selection operation are completed, the operator touches the reading reservation button 702. As a result, the image data is specified in correspondence with the cassette insertion order and the reservation selection order.

Then, the images of the persons having the specified names are read and displayed on the display unit 710 in the order of registration.
The reading of the radiation image is read by the apparatus main body 2 (see FIG. 2) and displayed on the display unit 710. That is, images are displayed in the order of registration. When the observation of the image is completed, the operator touches an OK button 721. Then, the displayed image is finally determined, and processing for outputting the image data and storing the image data in the storage unit can be performed.

As described above, if the image displayed on the image display unit 710 is appropriate as a diagnostic image,
Touch the K button 721. Thus, the image data is finally determined and can be output to a printer or the like.

FIG. 5 is a diagram showing the correspondence between the read size and the output size. In the figure, three types of reading sizes A to C are provided as reading sizes (here, cassette sizes). On the other hand, the output size is (a) the same size as the cassette (1-3), (b) is one size (3), and (c) is two sizes 1 and 3.

Conventionally, a fixed output size has been allocated to the plurality of types of read sizes as shown in (b). In the present invention, as shown in the figure, the output size can be designated from among a plurality of output sizes as shown in the figure, according to the reading size (cassette size).

FIG. 6 is a flowchart showing the operation of the present invention. The storage unit stores a correspondence table indicating the relationship between the read size and the output size as shown in FIG. 7 in advance. As shown in FIG. 7, the correspondence table associates the read size (cassette size) with the corresponding output size. For example, the output size is determined as “3” for the read size “D”.

First, when a cassette is loaded (S1), C
The PU 60 detects the reading size from the size of the cassette (S2). When the reading size is detected, the CPU 6
0 refers to a correspondence table as shown in FIG. 7 (S
3). When the reading size is determined, the CPU 60 proceeds to FIG.
The output size corresponding to the detected reading size is determined from the correspondence table as shown in (4) (S4).

As described above, according to this embodiment,
An image can be recorded on an image recording medium having an optimum output size corresponding to the reading size. FIG. 8 is an operation explanatory diagram of the second present invention. In FIG. 1, reference numeral 1 denotes the above-described image reading device, and reference numeral 2 denotes a printer that prints image data read by the image reading device. The figure shows a case where the printer 1 and the printer 2 are connected. The image reading device 1 and the printer 2 are connected via a bus 3 and constitute a LAN. Printer 2 used here
You can select only two types of magazines containing recording films to be mounted on the camera. The magazines loaded in the printer 1 are E and F, and the magazines loaded in the printer 2 are G and H. The types of these magazines E, F, G and H may be the same or different. As the type of magazine, for example, a size such as six cut or half cut can be selected.

In this case, when the image read by the image reading device 1 is printed, the above-described correspondence table (see FIG. 7) is provided. And CPU
In 60, the number of connected printers and the type of magazine loaded are notified in advance. Then, when the operator touches the OK button 721 from the screen shown in FIG.
The image size is determined and the image size is determined. For example, assuming that a cassette 9 records a radiation image equivalent to six slices, a film magazine on which a six-slice size film is mounted is selected.

The image data recorded in the cassette 9 is read out in order and recorded in, for example, a magazine E mounted on the printer 1 (when the magazine E is a six-cut size). According to this embodiment, an image can be recorded by determining an optimum film size in accordance with the size of the cassette.

According to the present invention, it is possible to select a printer according to the cassette size of an image. When outputting an image, the CPU 60 outputs the image to the printer 2 corresponding to the cassette size. According to this embodiment, it is possible to select a printer according to the cassette size.

Further, according to the present invention, a condition setting mode for setting printing conditions is provided, and the photographing part, resolution, reading size, rotation angle, printer type, and gradation characteristics are set as the condition setting mode. To print. When you touch the OK button 721,
The print condition setting screen is displayed. The operator, on the print condition setting screen, sets the imaging region, resolution,
The reading size, rotation angle, type of printer, gradation characteristics, etc. are written. As a result, when printing an image on a film, the image can be printed according to the set conditions.
