Abstract

PURPOSE:To eliminate a synchronizing step-out between a print frame and a frame number even when a film is fed backward by reading a frame code with a preread notcher and recording notch interval data on a recording medium. CONSTITUTION:While the film F is moved by a film driving part 14, a splice detector 151 detects a splice and the position of an end surface close to a next screen is stored and a screen detector 152 performs screen detection and after DX code detector 153 and a frame code detector 154 detect a DX code F2 and a frame code F3, a notch is applied when a screen detected by the screen detector 152 reaches a notch part 16. Then data obtained by visually deciding the read data of each detector previously through a film viewer is recorded on a cassette recorder 18 together with the data inputted on a keyboard 17. Therefore, the inner size distance from a splice inner end surface is recorded in either film feeding direction. Consequently, the synchronizing step-out between the print frame and frame number is eliminated.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for synchronizing print frames and frame numbers when a plurality of photographic films are spliced together and subjected to continuous printing. Regarding the technology used.

[Conventional technology]

Numerous techniques have already been disclosed for producing film by intensively printing multiple photographs in a laboratory. That is, there is a DX code and a frame code that are provided near the side edge of the film, but in addition, in the printing process after film development, a screen (frame) is placed on the side edge of the film using a pre-read notch prior to processing.
It is also known that a notch is cut out at a location corresponding to the center position of. This notch plays an important role in positioning the screen during later burn-in processing.

Films with additional information added in this way are also made up of multiple pieces connected by splices to form a long roll, and each screen is sent in sequence and printed based on the order data and correction data. When processing the film, it will be difficult if the recorded data and the screen of the film concerned are not synchronized. Since the distance between the splice that connects the film and the screen of the film cannot be made exactly equal, it is important to record the position from the splice to the screen individually as data, which can be done after development to maintain synchronization. It is necessary to include additional information based on the premise that However, if one-way distance data is simply created from the splice, this data will no longer be usable when the film is fed backwards.

[Problem to be solved by the invention]

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a photographic printing apparatus in which the print frames and frame numbers do not deviate from synchronization even when the film is fed in reverse.

[Means to solve the problem]

The purpose of this is to read the frame code with the flap lead notch, record the notch interval data on the recording medium along with the judgment data and frame number data for the corresponding photographed frame, and use the inner distance data in the printer. Photo printing is achieved by the apparatus, which is characterized by eliminating synchronization between print frames and frame numbers.

Here, pre-read noncha means 7235 m after development.
This refers to a device that makes a semicircular notch on the side edge of the film corresponding to the center of the image on a roll film of 2 mm.The 2-notch notch uses a sensor to read the frame code of the film and This is done by detecting the screen with a detector and determining its center position.
Regarding this work, all read data is recorded on a recording medium. The data includes a frame code, judgment data indicating the conditions for printing each photographed frame, a frame number, a notch interval, and an interval from the notch on the most edge screen to the nearest splice end face. This makes it possible to use inner distance data.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is an external view of the pre-read notcher 1, and FIG. 2 is a block diagram. In FIG. 1, the film is driven by a film drive section 14 and is wound from a film source winding section 11 to a film transport section 12, a film pure 13, and a film winding section 15. During that time, the film passes through the film detection section 7077 and the notch cutout section 16. The data visually determined using the Film Pure 13 is entered using the keyboard 17 and recorded on the cassette recorder 18. However, the recording medium is not limited to a cassette recorder. Second
The configuration and operation of the embodiment are shown in a block diagram with respect to the drawing in which a plurality of films are connected by splices and one film (7) is rolled out. For the second reason, there are a splice detector 151, a screen detector 152, a DX code detector 153, and a frame code detector 154 on the upstream side in the moving direction of the film F.
077 Part 10. These detectors consist of charging sensors. While the film F is moved in the direction of the arrow by the film drive section 14, splice detection is performed by the splice detector 151, the position of the end face near the next screen is memorized, and then the screen is detected by the screen detector 152, and the DX code is detected. The detector 153 and the frame code detection 5154 read the DX code F2 and the frame code F3.Then, the screen detector +52 detects the detection screen.
6J: Notch cutting is performed at the point reached.

In this embodiment, prior to cutting out the notch, the data read by each detector is recorded on the cassette recorder 18 together with the data visually determined using Film Pure and the data entered using the keyboard 17.

To explain the operation with reference to FIG. 2, first, when film transport is started, a signal synchronized with the stepping motor 14a of the film drive section 14 is sent from the control section 21 to the AD converter 22 for bar food detection. DX code detector 1
Since the bar code format consists of two tracks, the output from the sensor 53 is divided into two parts, and the sensor output on the clock bit side is input to the amplifier 23A, and the sensor output on the data focus side is input to the amplifier 23B. Furthermore, the sensor output from the frame code detector 154 is transmitted to the amplifier 24.
is input.

The AD converter 22 performs AD conversion on these outputs and inputs them into the barcode calculation processing section 25 . Next, the output from the screen detector 152 to the frame end face of the screen Fl passes through the amplifier 26 and is AD converted by the AD converter 27, and the screen detection processing section 28 detects the screen position.

The control unit 21 calculates the center position of this screen, drives the notch cutout part 16 via the notcher drive unit 29, and creates a semicircular notch F4 at the film side edge of the screen center position.
Add. The notch spacing and the spacing between the nearest notch at both longitudinal ends of the film and the nearest splice end face, respectively, constitute inner distance data for one film, and recorded on a cassette recorder.

With this configuration, the inward distance from the inner splice end face is recorded regardless of the film feed direction, so there is no need to correct the splice length etc. when reading the record, and the recorded data can be used as is. There are advantages to using it.

〔Effect of the invention〕

It was possible to put the device into practical use for photo printing without synchronization of print frames and frame numbers.
