Next, a method for printing a latent image on a film using the apparatus for printing a latent image on a film according to the embodiment of the present invention will be described.

First, the operator opens the cartridge access door 32 and sets the two cartridges 31a and 31b with built-in films on which the latent images have not been burned into the cartridge holder 33. Next, the operator presses the automatic operation button 71 to start the operation of the latent image burning device 30 for the film.

When the control unit 80 of the film latent image printing apparatus 30 detects that the automatic operation button 71 has been pressed, it closes the cartridge entrance / exit door 32 to bring it into a dark room state. Thereafter, as shown in FIG.
The cylinders 40a and 40b are driven by a and 41b to move the cartridge holders 35a and 35b in the holding direction D2. Thereby, the cartridge 3 with built-in film
1 a and 31 b are fixed in the cartridge holder 33.

Next, as shown in FIG.
The arms of the films 34a, 34b protruding from the film built-in cartridges 31a, 31b are moved and held in the direction D6 by the film clampers 42a, 42b positioned at the initial positions of the drawers a, 34b. I do. After holding the films 34a and 34b, the slider 44 is slid in the slide direction D4 to draw out the films 34a and 34b while floating. At the same time as the films 34a and 34b are pulled out, dust on the original image sheets 38a and 38b is removed by brushes 68a and 68b.

Here, it is determined whether or not the films 34a, 34b have been completely pulled out of the film-containing cartridges 31a, 31b. Specifically, the light source 65a,
The infrared light from 65b is detected by the optical sensors 66a and 66b, and the determination is made based on the detection result. Film 34
When it is determined that the films 34a and 34b have been completely pulled out, the moving mechanism 51 moves the film pressing portion 50 in the downward direction D5, and the films 34a and 34 drawn out.

As shown in FIG. 5, the needles 64a, 74a of the perforating units 64, 74 are used for the film 34.
A hole is made in a and b, and marking is performed to indicate the burning of the latent image.

It should be noted that whether or not the strobe light has been emitted by the strobe unit 60 is determined based on the detection result of the optical sensor 62. If the strobe light has not been emitted, the latent image is formed on the films 34a and 34b. Is not burned in, so that holes are not formed in the films 34a and 34b by the hole forming units 64 and 74. Further, the warning unit 81 warns the operator that the latent image is not burned by voice or message display.

Thus, the operator can easily determine whether or not the latent image has been printed on the film in the cartridge with a built-in film. It is possible to prevent printing of a latent image.

After the marking indicating the printing of the latent image is performed, the arms of the film clampers 42a and 42b move so as to open the films 34a and 34b.

Further, the slider 43 is moved in the sliding direction D3.

31b is removed from the spool. Further, the film retainers 35a and 35b move in the retaining direction D2, and the fixing of the film built-in cartridges 31a and 31b is released.

Finally, the cartridge access door 32 is opened. This allows the operator to take out the film cartridges 31a and 31b from the cartridge holder 33. At this time, the film 34 slightly exposed from the film built-in cartridges 31a and 31b is used.
Since the markings indicating the printing of the latent image are given to the leading ends of the a and 34b, the operator can confirm that the latent image is a film on which the latent image is printed.

In the embodiment of the present invention, a case has been described in which a latent image is printed on films in two cartridges with built-in film. However, it is possible to print a latent image according to the present invention.

In the embodiment of the present invention, direct light from the strobe unit 60 is prevented, and the film 3
In order to make the exposure amount for 4a and 34b more uniform,

It is possible to provide a mask 85 having ND (Neutral Density) filters 85a and 85b between them. The ND filters 85a and 85b provide a quantity of light corresponding to the density of the original images of the original image sheets 38a and 38b to be burned for each photographing frame of the films 34a and 34b, as needed, and Can be burned, and the film 34a,
34b has the function of adjusting the light amount for each photographing frame.

Specifically, the original image sheets 38a, 38b
When the original image of each frame recorded in the original image has a low density of the entire original image and the original image is whitish, for example, a frame that is mostly white, the latent image of the white portion is high after the development processing. Since it is necessary to perform printing so as to have a negative density, the amount of light applied at the time of printing is increased. on the other hand,
When the original image of the frames recorded on the original image sheets 38a and 38b has a high density of the entire original image, and the most of the original image is colored, the same as when the original image is a whitish frame When the latent image is printed with the amount of light, the negative density after development processing of the colored part becomes too high, so the amount of light given when printing the latent image is smaller than when the original image is a whitish frame I do. By doing so, it is possible to print a latent image that can obtain a print in a color closer to the original image.

In place of the above-described method of adjusting the light amount for each frame using the ND filter, a plurality of light sources different for each frame are used so that different light amounts are provided for each photographic frame of the film. Alternatively, the light amount may be changed for each light source, or the light amount may be adjusted for each frame using a plurality of light sources and an ND filter.

Further, in the embodiment of the present invention, exposure using indirect light is performed as in the case of FIG.
