Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for making films such as colored slide films.

There has been a desire to create a conventional slide film in which the text portion is transparent and the background portion is colored, for example, blue.

However, in the past, when actually creating such a slide film, for example, when using silver halide color film, the original image was created with white text written on blue colored paper, and this was photographed. This method requires a lot of time and effort to create the original image, and the post-processing is also troublesome, making it difficult to quickly and easily create an original image when needed.

In addition, using a film coated with a diazo layer, a silver salt black and white negative film is exposed to a close-contact electric light to decompose the diazo layer in the exposed areas, and then exposed to ammonia vapor to color the diazo layer. Another method is to create a slide film of colored negative images.

However, since this method uses silver salt black and white negative film, it is easy to prepare the original image by simply preparing black letters on white paper, but ammonia vapor is used to color the diazo layer later. As a result, there were problems such as a bad odor being generated and a considerable amount of time being required for color development.

The present invention aims to provide a blue film forming apparatus that can solve the above-mentioned problems.

The present invention will be described below based on illustrated embodiments, but before that, the copy film (diazo film) used in the present invention and its red coloring process will be explained.

In FIG. 1, 1 is a transparent base film made of polyethylene terephthalate or the like, and one side of this film is coated with a diazo layer 2 made of decomposed diazo sulfonate and Kabra in a binder.

Note that the diazo layer 2 of this film is yellow before use.

Further, in this embodiment, the film is mounted on the slide frame 3 to facilitate handling, and after being prepared, it can be immediately loaded into a slide projector and used.

In order to color the film, it is sufficient to heat it while irradiating it with light, and the diazosulfonate and the coupler react in that area to develop a blue color.

On the other hand, in the areas that were only heated without being irradiated with light, the above-mentioned coloring reaction did not occur and the original yellow color was maintained.

The above-mentioned light irradiation amount is 5 million lux seconds and the heating temperature is 1.
A good coloring reaction occurs when the temperature is about 00°C.

Next, when the entire surface of the above film is irradiated with light of about 20 million lux seconds without heating, the diazo layer in the parts that were not colored because the light was not irradiated decomposes, releasing nitrogen gas and becoming colorless. (transparent).

(This process will be referred to as fixing process hereinafter.

) Figures 2 and 3 are front and side cross-sectional views of an embodiment of the present invention in which a reversal slide film is prepared using the diazo layer coloring process described above.

A holding plate 15 is provided for inserting and holding the
The inserted color-developed copy film 12' is arranged to be fixed by near-ultraviolet light.

In this embodiment, two copying fluorescent lamps having a peak at about 4001 m (nanometer 10-9 m) are used as the fixing lamps 14.

Further, the above-mentioned lamp 5 is made to blink by a time switch 17 linked to the knob 16.

Note that the fan 6 is disposed in the third room, communicates the first room and the third room through holes (ventilation passages), and cools the coloring lamp 5 and the original film 9.
The second chamber and the third chamber are communicated with each other through a hole (not shown), and the fixing lamp 14 is also cooled.

FIG. 4 shows the lamp 5. shown in FIGS. 2 and 3. 2 is an electrical wiring diagram in this embodiment of the present invention for coloring and fixing the copy film 12 by energizing the fan 6, heater 13, and fixing lamp 14. FIG.

When the part corresponding to the transparent part 2 becomes colorless and transparent, it is taken out from the fixing position.

The sheet copy film 21 is mounted on the slide frame 25 as shown in FIG.
to be loaded.

Then, the heater 13 comes into close contact with the copy film 21 and heats it.

At the same time, when the knob 16 is turned without putting any original film into the original film holder 8, the time switch 17 is activated, the lamp 5 is turned on, and the entire surface of the copy film 21 is irradiated with light, and the light is emitted during the fixing process. A coloring reaction occurs in the portions of the original film 22 that are not hit by the opaque portions, resulting in a blue color, and a colored slide film similar to the original film 22 can be produced.

As is clear from the above description, the present invention includes a first film holder that holds a copy film coated with a diazo layer, a second film holder that holds an original film, a lens, a light source, and a copy film. Since it is equipped with a heating element that causes a color reaction in the diazo layer of the film, it is very easy to operate and has a simple structure, and does not require a fixer or developer, and can be used from either negative or positive. In addition, colored films can be obtained in a short time from both films with sliding frames and sheet-like films.

Also, the first chamber and the third chamber are communicated, and the second chamber and the third chamber are connected to each other.
