[Detailed description of the invention] 1. The present invention 1 relates to a DχX code acquisition/conversion device,
In particular, the DX code is designed to read the DX code recorded on photographic film and automatically output the optimal total printing light conditions according to the type of photographic film to the printer device that prints the photographic film. Regarding reading/converting devices.

[Prior Art] In a printer device that prints images by exposing and printing images on photographic film, exposure conditions are set during printing so that real colors, etc. can be faithfully reproduced. There is. One of these conditions is the print channel. This print channel corresponds to, for example, 7 types of photographic film (mechanical, camera, film sensitivity), printer device, photographic paper, processing solution, developing conditions (developing speed, developing temperature, etc.). - is used to set the exposure conditions for printing.

(Problem to be Solved by the Invention) However, in conventional printer devices, an operator manually reads the DX code of the photographic film, and based on this, inputs each DX coat information into the printer device. Therefore, since the DX coat information is manually read and transferred to the printer device, there is a risk that reading or input errors may occur, and printing defects may occur.

The present invention was made to solve the above problems, and instead of manually reading and inputting the DX code, it automatically reads the DX code and detects the film type, photographic paper, printer device, developing solution, etc. It is an object of the present invention to provide a DxX code reading/converting device with a simple configuration, which can set optimal print exposure conditions in a printer device depending on the type of development conditions, etc.

In order to achieve the above object, the present invention includes a DX code reading means for reading the DX code recorded on each photographic film, and a grouping of DX codes that produce the same print result among a plurality of DX codes. a first storage means storing DX code table numbers representing these groups and D'X code tables representing relationships between DX codes belonging to each group; each DX code table number;
and a second storage means that stores a print channel table in which print channels are associated with each other to select film type information, and a DXX code reader means that reads the DX code by referring to the Dx coat table number 1 and the print channel table. A search means for searching and outputting a print channel from the print channel is provided.

6□, □, the present invention, which achieves the target. , DX for reading the DX code recorded on each photographic film.
A code reading means and a plurality of DχX codes that have the same presito result are grouped together, and a DX code table number representing these groups and a DX code table representing the relationship between the DX codes belonging to each group is generated. Storage-5= A print channel table in which the first storage means corresponding to each DX code table number and a print channel for selecting film type information is stored according to the type of photographic paper used in the printer device. a second storage means storing a plurality of sets; a table selection means for selecting one print channel table according to the type of photographic paper from the plurality of print channel tables stored in the second storage means; A search means is provided for searching and outputting a print channel from the DX code read by the DX code reading means by referring to the DX code table and the selected print channel table.

[Operation] When the DX code of the photographic film is read by the DX code reading means, based on the read DX code, the print corresponding to the type of the read X code is determined based on the DxX code table and print I-channel table in the storage means. A channel is retrieved and this print channel is output to a printer device. Therefore, unlike in the past, there is no need to manually read the DχX code of the photographic film J and manually input it to the printer device.
The print channel corresponding to the type of DX coat applied can be automatically input into the printer device.

To search for a print channel that corresponds to the type of X code being read and, for example, the type of photographic paper, first search the same code as the X code being read from the DX code list, and then select the D Read the code table number, search the print channel table in the second storage means selected by the table selection means according to the type of photographic paper for the same table number as this DX code table number, and select the corresponding print channel. It is done by reading. In this way, by searching for the optimal print channel for the printer device in accordance with the read X code and, for example, the type of photographic paper, it is possible to determine the type of film and photographic paper without using complicated calculation formulas. Accordingly, optimum print exposure conditions can be easily set on the printer device. This eliminates the need for arithmetic expressions and arithmetic devices for processing them, making it possible to simplify the configuration.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, this embodiment includes a DX code reading means 1 for reading the DxX code recorded on each photographic film, a first storage means 2 for storing a DX code table, and a print channel table for storing a print channel table. a second storage means 3 in which one print channel is selected according to the type of photographic paper used for printing from a plurality of print result channel tables in the second storage means 3; Based on the above, the present invention comprises a search means 5 for searching and outputting the print channel of the printer device from the DX code of the photographic film read by the reading means 1.

As shown in FIG. 2, the D.x. This barcode sensor 12
Detects the DX code recorded as a barcode on the side edge of the photographic film 13. As shown in FIG. 3, this barcode sensor 12 is placed in a film insertion stand 14 having a groove 14A for passing photographic film 13 therethrough. The film insertion stand] 4 is attached to the main body side of the DχX code acquisition/conversion device so that it can be raised and lowered freely, and when it is in a horizontal state, the film can be inserted horizontally. In the vertical state shown, the film can be inserted vertically.

The storage means 2.3 and the search means 5 are constituted by a microcomputer 15, as shown in FIG. As is well known, the microcomputer X5 is a C
PU16, RO'M17, RAM18, decoder 19,
Each register 20.21, parallel/serial converter 22
A, 22B, 11023A, 23B, etc., and further includes a print channel display 24, selection table display 25, table selection switch 26, buzzer 27, hand terminal 28,
It is equipped with a comparator '29C for converting the output signal from the barcode sensor 12 into a digital signal.

In the RAM 18, an X code table 30 as shown in FIG. 4 and print channel tables 35A-D as shown in FIG. 5 are stored. D
The X code table 30 is a table for dividing 4-digit hexadecimal DX codes into groups with almost the same print results, identifying and registering these groups with DX code table numbers, and is 1 to 16. (in the coordinate X direction in FIG. 4), and up to 16 DXX codes can be stored in the width of one table number.

In this DX code table 30, if the DX code to be registered has already been registered in the width of another table number, the registration of this code -10= is not accepted as an incorrect input. Note that the same DX code with the same table number and width is allowed.

As shown in FIG. 5, the printer 1 to channel tables 35A-D are tables for registering a 2-digit decimal print channel and a 2-digit DX code table number as a set. be. A plurality of tables are stored in accordance with the types of photographic paper used in the printer device. For example, four tables 35A are required for four types of color paper (color photographic paper).
-D is stored.

As the print channel, numbers in the range of 0 to 99 are used, and it is also possible to register duplicate print channel values in one table.

In addition, numbers in the range of 1 to 16 are used as Dχ code table numbers, and duplicate DX codes in one table are
Registration of the code table number value is considered to be an illegal input and is not allowed to be registered.

The table selection switch 26 selects a plurality of print channel tables 35A to 35 stored in the RAM 18.
This is for selecting one print channel from D according to the type of color paper. Note that the reference numeral 29A in FIG. 3 indicates a display selection switch. This switch 29A displays D on the print channel display 24.
This selection is made to display either the X code read data or the searched printer channel. Further, reference numeral 29B indicates a communication device selection switch. This switch 29B is used to select the target to which the DX code reading/search results are to be sent. When in the OFF state, the reading/search results are simply displayed on the display 24, and when in the ON state, it is sent to the printer device. This is for transmitting a print channel. Further, the hand terminal 28 is
It is used to rewrite each of the tables 30, 35A-D in the RAM 18, and is composed of a keyboard and a display.

Next, referring to flowchart 1 shown in FIG.
The operation of this embodiment will be explained. First, a DX code is read from photographic film by a barcode sensor. The signal from the barcode sensor 12 is converted into a digital signal by a comparator 29C. DX code read,
For example, “0203” is stored in the register 20.

Next, read the X code r from the DX code table 35.
0203. Same code as r0203. to determine whether the same code exists. If the same code is not found, it is determined that there is no compatible printer channel, the buzzer sounds twice, and the process returns to the start. If there are identical coats, the DX code table number to which the DX coat belongs is extracted from the DX code table 30. For example, in table 30 of FIG. 4, the read X code is r
o In the case of 203J, the DX code table number is "2".

Then, the table selection switch 26 searches the print channel table currently selected according to the type of color paper for the same DX code table number,
Determine whether the same table number exists. 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.

Furthermore, if the same table number exists, the print channel paired with that table number is extracted from the print channel table. For example, when the table "2" is selected by the table selection switch 26, the DX code table number "2" is searched from the table "r2" (35B) in FIG. In this case, "02" is located at position "2" in table "2", and print channel "31J" paired with DX code table number "2" is taken out at position "2".

Next, it is determined that there is a compatible print channel and the buzzer 2
7 is sounded once, and, 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, and the read X code and table selection table are read.
Since the print channel of the printer device is taken out from the table based on the type of color paper used from 6 and sent to the printer device, DX can be performed without manual intervention.
Based on the code and type of color paper, it becomes possible to automatically, quickly and accurately set the optimal print channel corresponding to these in the printer device.

In the above embodiment, four print channel tables are provided corresponding to four types of color paper, but the present invention is not limited to this, and the number of print channel tables may be increased or decreased as appropriate. Can be done. For example, a printer device that uses only one type of color paper may have one print channel table. In this case, there is no need to select a print channel table, so the table selection switch 26 can be omitted.

Further, in the above embodiment, the optimum print channel is selected depending on the type of film and the type of photographic paper, but the present invention is not limited to this.
An optimal print channel can also be selected depending on the type of film, printer device, processing solution, development conditions (development speed, development temperature, etc.). In this case, a necessary number of print channel tables are stored in the storage means of the cylinder 2 depending on the type of printer device, processing solution, development conditions, etc.

〔Effect of the invention〕

As explained above, according to the present invention, D representing a group
X code table number and D belonging to each group
With reference to the DX code table representing the relationship between X codes and the print channel table representing the correspondence between DX code table numbers and print channels, the search means prints based on the DX code of the photographic film read by the DX code reading means. Since the channel is searched and the searched print channel is output to the printer device, the DX code is read without manual intervention and the print channel most suitable for the film type is automatically, quickly and accurately set in the printer device. can do.

Moreover, the most suitable print channel is searched based on the X-code read by referring to the above two tables, depending on the type of film, photographic paper, printer device, processing solution, development conditions, etc. A print channel can be easily output to a printer device without performing complicated calculations, and the device configuration can be simplified.
