Abstract

PURPOSE:To perform burning-in without using any optical system and without using any negative plate by providing the picture elements on an electrical display device generated in synchronization with the conveyance of a film so as to face to a film plane at a very small distance. CONSTITUTION:The conveying speed of a roll film F conveyed by a film conveying means 1 is detected with a detection means 3 for conveying speed, and a synchronizing signal is fed to a control device 4 for generation of characters, etc. The information on burning-in is beforehand made in the device 4 and a signal is sent to a driving device 5 so as to display picture elements such as characters in the one-dimensional line in the direction at a right angle to the conveying direction of the film F in accordance with the signal from a means 2 for detecting the burning-in position of the film. Then the picture elements are displayed one-dimensionally on an electric display device 6. Since the display device 6 is disposed so as to face to the film plane of the film F at a very small distance therefrom, the characters, etc. are burned-in directly on the plane of the film F without using any optical lens system or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a baking device for photographic film for imprinting frame characters and the like on the edges and the like of photographic film.

Photographic film, especially photographic roll film, has so-called side marks, such as symbols indicating film characteristics and the manufacturer's brand name, and a frame number indicating the number of frames to be taken, printed on both edges of the film. .

The present applicant had previously proposed the above-mentioned coloring apparatus in Japanese Patent Application Laid-Open No. 56-83730 or Japanese Utility Model Application No. 56-3834.1. In all of these baking devices, a negative plate corresponding to the baking letters is prepared,
This is printed onto the running film in synchronization using optical means, and is unique in that it is printed using a pulsed light source. Due to maintenance problems in the
According to the specification of No. 9171, characters, etc. are generated on an electric display device by a character generation control device, and the characters, etc. on the electric display device are imprinted on the edges of photographic film using an optical system, and a negative plate is produced. We have proposed a printing system for photographic film that does not use.

However, since this system uses an optical system to transmit images, there is a possibility that the image may become blurred due to aberrations and positional shifts in the optical system, monitoring and confirmation are required, and maintenance is cumbersome. There's a problem.

Therefore, in order to solve the above-mentioned problems when printing using an optical system, the present invention aims to generate pixels of characters, etc. on an electric display device with good directionality using a character generation control device in synchronization with the conveyance of the film. The pixels on this electric display device are brought close to the film surface at a very small distance, and printing is performed, thereby making it possible to take photographs without using an optical system or even using a negative plate. The present invention provides a film baking device.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a layout diagram of the components of the photographic film baking apparatus of the present invention. F is for burning.'>,! : A roll film that is transported in the direction of the arrow by the film transport means 1 that controls the running of the roll film F. In this embodiment, the film conveying means 1 has a film processor 5, which controls the light receiving position at the edge of the roll film F. 2 is a film baking position detecting means that detects the baking position of the roll film F being conveyed and generates a signal, and is an optical detector using a timing cam linked to the perforations of the roll film F or a film sprocket drum, etc. Consists of etc. Reference numeral 3 denotes a film transport speed detecting means for detecting the film transport speed and generating a film synchronization signal, which operates in conjunction with the film transport means 1, and is usually a rotary encoder or the like. Reference numeral 4 denotes a character generation control device which prepares printing information in advance and generates characters, etc. on a one-dimensional line in a direction perpendicular to the transport direction of the roll film F based on a signal from the film burning position detection means 2. The display of the pixels starts, and thereafter the roll film F is controlled to display the same number, etc. by the synchronization signal from the film transport speed detection means 3. Reference numeral 5 denotes a driving device for the electric display device 6, which converts signals from the character generation control device 4 into conditions that allow formation of pixels of the electric display device 6. The electric display device 6 has one-dimensional pixels, and is made of an optical fiber recording tube with good directivity of the pixels on the tube surface, or a recording tube using a laser, such as an LE.
L) A recording tube or the like in which a large number of liquid crystals are arranged is used. This electric display device 6 is disposed facing the film surface of the roll film F at a very small distance, and is designed to directly burn characters and the like without using a lens optical system or the like.

FIG. 2 is a program flowchart for the character generation control device 4 in the photographic film baking apparatus of the present invention.

First, the engraving specification conditions are obtained from the setting device of the character generation control device 4. Next, supplementary signals such as barcode signals from the outside are taken in to select and determine the printing contents. Then, a character generator with a dot matrix display is used to allocate characters to be burned to the burning positions according to the program, and the information necessary for full color burning is stored in a storage memory (called an image ram in the figure). Make me remember.

Then, based on the signal generated by the film baking position detection means 2 as the roll film F travels, one-dimensional pixel content of the image ram is determined by a horizontal deflection signal (H in FIG. 2).
, 5YNO signals) and video signals (denoted as V, 5YNO signals in Figure 2)
T, R, signals) are turned OFF and output to the electric display device 6 via the drive device 5 is started. Thereafter, a one-dimensional pixel display signal synchronized with the roll film F is output by the synchronization signal of the film transport speed detection means 3,
All information such as burnt characters and symbols is created on one side of the flowing roll film. Then, the above sequence is repeated to perform burning until a work stop command is received.

FIG. 3 is a conceptual diagram of image formation by the photographic film baking apparatus of the present invention. This figure shows the roll film F on the film conveying means 1 developed in a straight line, and the emulsion side of the roll film F, especially the central parts PNl and PNI of the printing progressing part PN, are now -dimensional pixel display. PP2-Song-.

PN2-......indicates a burnt color pixel portion. The resolution of the vertical and horizontal dot spacing of each pixel can be selected depending on the required image quality, making it possible to print with appropriate image quality.

In the above embodiment, if the roll film F is limited to being transported at a constant speed by the film transport means 1, the film transport speed detection means 3 can be replaced with a clock pulse generated within the character generation device, and is therefore unnecessary, making it simple. The structure is as follows.

Furthermore, when the roll film 1 is stopped, the electric display device 6 is turned off.
Alternatively, the electric display device 6 may be moved while the roll film 1 is being conveyed, and the relative speed may be set to a low speed for printing.

As described above, according to the present invention, in synchronization with the conveyance of the film, the character generation control device generates pixels such as characters on the electric display device that is disposed facing and close to the surface of the conveyed film at a very small distance. This allows the film to be directly colored without using an optical system, so there is no blurring due to aberrations caused by image transmission using an optical system, and furthermore, There is no need for monitoring and confirmation, maintenance management is easy, and burning is performed with good responsiveness to changes in burning conditions.
