6, ROM17, RAM18, decoder 19, registers 20, 21, parallel / serial converters 22A, 22B, I / O 23A, 23B, etc., and a print channel display 24 for a DX code reading / converting device. , A selection table display 25, a table selection switch 26, a buzzer 27, a hand terminal 28, a comparator 29C for converting the output signal from the bar code sensor 12 into a digital signal, and the like.

In the RAM 18, a DX code table 30 as shown in FIG. 4 and print channel tables 35A to 35D as shown in FIG. 5 are stored. The DX code table 30 is a table for dividing a 4-digit hexadecimal DX code into groups in which the print results are almost the same, and identifying and registering these groups with the DX code table numbers. It has a code table number (coordinate X direction in FIG. 4), and in the column of one table number,
It is designed to store up to 16 DX codes. In the DX code table 30, when the DX code to be registered is already registered in the column of another table number, the registration of the DX code is prohibited as an invalid input. In addition, the same DX code in the column of the same table number is allowed.

As shown in FIG. 5, the print channel tables 35A to 35D are tables for registering a print channel having a 2-digit decimal number and a DX code table number having a 2-digit decimal number as a set. This table is
A plurality of sets are stored according to the type of printing paper used in the printer device. For example, four tables 35A to D are stored for four types of color paper (color printing paper).

The signal from the barcode sensor 12 is converted into a digital signal by the comparator 29C. The read DX code, for example, “0203” is stored in the register 20.

Next, read the DX code “020 from the DX code table 35.
The same code “0203” as “3” is searched to determine whether the same code exists. If there is no same code, it is determined that there is no corresponding print channel, the buzzer sounds twice, and the process returns to the start. If there is the same code, DX
The code table 30 extracts the DX code table number to which the DX code belongs. For example, the table in Figure 4
In 30, when the read DX code is “0203”, the DX code table number is “2”.

Then, the same DX code table number is searched from the print channel table currently selected according to the type of color paper by the table selection switch 26, and it is determined whether or not there is the same table number. If there is no same table number, it is determined that there is no corresponding print channel, the buzzer sounds twice, and the process returns to the start.

If there is the same table number, the print channel that is paired with the table number is taken out from the print channel table. For example, when the table “2” is selected by the table selection switch 26, the same D is selected from the table “2” (35B) in FIG.
Search for the X code table number “2”. In this case, there is "02" at the position "2" in the table "2", and the print channel "31" paired with the DX code table number "2" is taken out at the position "2".

Next, it is judged that there is a compatible print channel and the buzzer
27 is sounded once, for example, the corresponding print channel "31" is displayed on the print channel display 24, and this print channel "31" is transmitted to the printer device. After this, return to the start.

In this way, the DX code is read from the photographic film, the print channel of the printer device is taken out of the table based on the read DX code and the type of color paper used from the table selection switch 26, and it is necessary to manually send the print channel to the printer device.
