DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame number printing method for an auto printer, and more particularly to a frame number printing method in a case where frame number data is out of synchronization in an auto printer.

[0002]

2. Description of the Related Art In large-scale developing laboratories, after a developed film is subjected to a negative inspection using a notch puncher or a negative inspection machine, the processed film is subjected to an automatic printer to print a large amount of the film. As is well known, a notch puncher adds a semicircular notch to a frame to be printed, inputs exposure correction data, and records the exposure correction data together with the frame position data on a paper tape or a recent LSI card. Record on the medium. At the time of printing, the recording medium and the film to be printed are set in the auto printer. The auto printer sets the print target frame at the print position based on the notch, specifies the exposure correction data from the LSI card, etc. from the frame position data, and automatically corrects the exposure based on the exposure correction data. Exposure.

[0003]

In the above-described auto printer, exposure correction data of a frame set at a print position is specified based on frame position data, and the exposure amount is automatically corrected based on the exposure correction data. Therefore, when the frame position data and the frame actually set at the print position are out of synchronization and out of synchronization, automatic exposure correction based on the frame position data becomes impossible. For this reason, there is a problem that automatic printing cannot be performed thereafter. This data is out of sync.
Malfunction of the film feeder in the film carrier,
It occurs due to erroneous detection of a notch, furthermore, erroneous operation or the like.

By the way, in recent years, a frame number of a negative film has been printed on the back side of a printed photograph so that a frame can be easily designated at the time of additional printing. Since the frame number printing is performed based on the frame position data input to the recording medium by the notch puncher or the like, if the data is out of synchronization, the printing is automatically performed thereafter. There is a problem that can not be.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem. In an auto printer, even if frame position data does not match an actual frame and data is out of synchronization, the subsequent manual printing can be performed. An object of the present invention is to provide a frame number printing method of an auto printer capable of printing back a frame number on a print photograph without particularly inputting a frame number or the like.

[0006]

In order to achieve the above object, the present invention detects a film feed amount and a frame number bar code at the time of film feeding when setting a frame to be printed at a printing position of a film carrier. Then, the frame position data is compared with the actual film feed amount to determine the data synchronization deviation, and when it is determined that the data is out of synchronization,
Switch from the auto print mode to the manual print mode, identify the actual frame number set at the print position of the film carrier from the detected frame number barcode, and print the frame number on the back of the print photo based on this frame number data Is performed.

[0007]

When the frame position data input at the time of the negative test and the like and the actual film feed amount do not match, it is determined that the data is out of synchronization. When the data is out of synchronization, since the frame position data input at the time of the negative test or the like cannot be used, the mode is automatically switched from the auto print mode to the manual print mode. During the detection of the data synchronization deviation, the frame number bar code is detected when the film is fed, in addition to the film feed amount. After it is determined that the data are simultaneously shifted, the frame number of the frame to be printed actually set at the print position is specified based on the frame number barcode read data. Then, based on the specified frame number data,
Prints the frame number during manual printing.

FIG. 1 shows a processing procedure at the time of detecting a deviation of the position data of the frame to be printed. FIG. 4 shows a functional block diagram of the controller 45. The operation of this embodiment will be described below with reference to FIGS. First, the film 10 to be printed is placed on the winding shaft 12 and L
The SI card 14 is set in the LSI card reader 13. Then, the film leader attached to the leading end of the film is passed through the transfer path of the film carrier 20 and then attached to the take-up reel 49. Thereafter, when printing is started in the auto print mode, the controller 45 sets the frame to be printed at the print position based on the notch detection signal of the notch sensor 41. This positioning is performed by feeding the film 10 in a fixed amount after detecting the notch. After setting the frame to be printed, the exposure amount is corrected based on the exposure correction data for each frame from the LSI card 14, and thereafter, the frame to be printed is printed and exposed. After the printing exposure, the paper 30 and the film 10 are fed by frame, and the next printing is performed in the same manner. At the time of this frame feed, the printing device 50 prints the frame number and the like.

During the automatic printing, the controller 4
Reference numeral 5 denotes a film feed amount at the time of frame feed of the film 10, and the film feed amount and the LSI card 14 are detected.
Is compared with the frame position data from. The film feed amount is obtained, for example, by counting the pulses of the pulse motor 39. As shown in FIG. 4, when the film feed amount and the frame position data no longer match, the data shift determiner 60 determines that the data is out of sync and automatically switches from the auto print mode to the manual print mode. As well as an out-of-sync signal

3 and to the selector 65. The alarm 61 issues an alarm by this out-of-sync signal.

The controller 45 operates the bar code reader 46 during the automatic printing, reads the frame number bar code and the DX bar code of the film 10 being printed, and stores the read data as it is. In a predetermined area of the memory 64. The frame number specifying calculation unit 62 reads out the frame number bar code read data read during the auto printing from the memory 64 at the time of the synchronization deviation, and calculates and specifies the frame number at the print position based on the read data. Selector 65
And sends it to the display 53. The selector 65 switches the frame number data in accordance with the synchronization shift signal, and selects the frame number data in the frame position data from the LSI card 14 in the auto print mode, and the frame number from the frame number identification calculation unit 62 in the case of data synchronization loss. The data is output to the printer 50. And at the time of manual printing,
Back printing is automatically performed based on the frame number data specified by the frame number barcode. As described above, the frame number is not specified during the auto print, but is specified only when a synchronization error occurs. Therefore, it is not necessary to perform a time-consuming frame number specifying calculation each time. Efficient arithmetic processing can be performed. The method of specifying the frame number based on the frame number barcode is described in detail in Japanese Patent Application Laid-Open No. 63-305336, Japanese Patent Application Laid-Open No. 1-12539, and the like.

The negative channel specifying unit 63 obtains a negative channel, which is the film type information at the print position, from the DX code data read during the auto printing by using a look-up table memory, and obtains the keyboard 52
This negative channel is displayed 53 according to the operation of
To be displayed.

In manual printing, an operator observes a frame to be printed, and inputs exposure correction data as necessary based on the observation result. Manual printing is performed, for example, for one order. Thereafter, after performing an operation of matching the frame position data of the LSI card 14 with that of the new order, the mode is switched to the auto print mode, and thereafter, the auto print is performed.

In the above-described embodiment, the film feed amount is indirectly detected by counting the drive pulses of the motor 39 for rotating the film feed roller pairs 37 and 38. The feed amount may be directly detected.

[0022]

As described above, according to the present invention,
During auto printing, the frame number barcode recorded on the side edge of the photo film is read, and if the frame position data is out of sync, the frame number is printed on the printed photo based on the frame number specified based on the frame number barcode. Since the number printing is performed, the frame number printing can be automatically performed even in the manual printing at the time of occurrence of the synchronization deviation.
