Abstract

PROBLEM TO BE SOLVED: To obtain a photosensitive material processing method by which an effect by damage or the attachment of dust is reduced even when a directional light source is used as a light source for illumination in the case that the image of a photosensitive material is photoelectrically read, the need of a countermeasure with respect to heat is eliminated, a cost is reduced and miniaturization is realized. SOLUTION: A film N is processed by being coated with water to such an extent that the water is left on the surface thereof after it is developed. A transparent glass plate 82 is pressed to the film N at a read part 76. Thus, if the surface of the film N is damaged, the water is enclosed in the damaged part. Under such a condition, the film N is irradiated with light and the transmitted image is read by a CCD sensor 92. In such a case, since the light refractive index of the water is near to the film N in comparison with air, the light is transmitted through the film N without being substantially affected by the damage of the surface. Therefore, excellent-quality image data is obtained.

2. Description of the Related Art In a method known as conventional color photography, a light-sensitive material for photographing (so-called color negative film) is usually a layer for recording blue light to form a yellow dye image and a layer for recording green light to a magenta dye. An image forming layer and a layer for recording a red light to form a cyan dye image, the developer is oxidized in the process of reducing silver halide grains containing a latent image to silver during the development processing, A dye image is formed by the reaction (coupling) between the oxidant and the coupler. Undeveloped silver halide and developed silver are removed in a subsequent bleach-fix step to give a color negative film with the dye image formed and the undeveloped silver halide and developed silver removed.

Conventionally, by irradiating the color paper with the light transmitted through the dye image of the color negative film,
The dye image is printed and exposed on color paper, and the same development,
I got a color print through the bleaching and fixing steps.

On the other hand, there is also known a method in which an image formed on the color negative film is photoelectrically read, and then image processing is performed to obtain image data for recording, and the image data is used to obtain an image on another image recording material. ing. In particular, the development of a digital printer for producing a finished print by scanning exposure of a photosensitive material such as color paper with laser light modulated in accordance with the above-mentioned image data as a digital signal, and an example thereof is disclosed in JP-A-7-15593. It is described in Japanese Patent Publication No.

By the way, in the above-mentioned method, when the image formed on the color negative film is photoelectrically read, a diffused light source is used as a light source for illumination in order to reduce the influence of scratches and dust on the color negative film. There is. However, such a diffused light source needs to have a high output in order to prevent a decrease in the amount of light. Therefore, it is necessary to take measures against heat, and it is difficult to reduce power consumption, reduce cost, and reduce size. Therefore, measures for this have been desired.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above facts, and when photoelectrically reading an image on a light-sensitive material, even if a directional light source is used as a light source for illumination, scratches and dust are generated. It is an object of the present invention to provide a method of processing a photosensitive material, which is less affected by the adherence of the toner, and which does not require heat countermeasures, consumes less power, and can be reduced in cost and size.

[0007]

According to a first aspect of the present invention, there is provided a method of processing a photosensitive material, which comprises exposing the image to a photothermographic material which is developed by heating, the exposed photothermographic material, and the photothermographic material. At least one of the processing sheets used to form an image on the photothermographic material by heating the material in superposition with a material is coated with a predetermined image forming solvent, and the image forming solvent is applied. After the heat-developable photosensitive material and the processed sheet are superposed, the superposed photothermographic material and the processing member are heated to develop the heat-developable photosensitive material to form the exposed image. Then, the photothermographic material on which the image is formed is peeled from the processing sheet, and the applied image forming solvent is exposed on the photothermographic material separated from the processing sheet by peeling. Is irradiated with light in the state remaining in reading the transmitted image obtained by the transmitted light, it is characterized in that.

In the light-sensitive material processing apparatus according to the first aspect of the present invention, in order to form an image on the heat-developable light-sensitive material, the image is exposed and the heat-developable light-sensitive material is overlaid and heated. At least one of the used processing sheets is coated with a predetermined image forming solvent. Water is usually used as the image forming solvent.

After the image forming solvent is applied, the photothermographic material is heated in a state of being superposed on the processing sheet. Here, the processed sheet is a member used for forming an image on the heat-developable photosensitive material by superposing it on the heat-developable photosensitive material and heating it. By being heated, the photothermographic material is developed and an exposed image is formed.

Further, the photothermographic material on which the image is formed as described above is peeled from the processing sheet, and the photodeveloping photosensitive material separated from the processing sheet by peeling is coated with the image forming solvent. In the state where the light remains, the light is irradiated and the transmitted image by the transmitted light is read.

In this case, when the photothermographic material is irradiated with light and the transmitted image is read by the transmitted light, the image forming solvent remains on the surface of the photothermographic material as described above. Therefore, if the surface of the photothermographic material has scratches or the like, the image forming solvent has entered (retained) in the scratches, and the surface of the photothermographic material becomes apparently smooth. Here, since the image forming solvent has a light refractive index closer to that of the photothermographic material than that of air, the transmitted light of the photothermographic material passes through the photothermographic material without being substantially affected by scratches. To do. Therefore, it is possible to obtain high-quality image data that is not affected by scratches or the like.

As described above, when photoelectrically reading the image on the photothermographic material, the influence of scratches and dust is reduced, so that high quality image data can be obtained even if a directional light source is used as the illumination light source. Therefore, it is possible to reduce the cost and the size by reducing the power consumption because no heat countermeasure is required.

A method of processing a photosensitive material according to a second aspect of the present invention is the method of processing a photosensitive material according to the first aspect, wherein the applied image formation is applied to the photothermographic material separated from the processing sheet by the peeling. It is characterized in that the transparent members are superposed while the solvent for use remains on the surface, and light is irradiated in the superposed state to read a transmitted image by the transmitted light.

In the photosensitive material processing apparatus according to the second aspect of the present invention, a transparent member is superposed on the photothermographic material while the coated image forming solvent remains on the surface, and light is emitted in the superposed state. Irradiate and read the transmitted image by the transmitted light.

In this case, since the transparent member is superposed with the image forming solvent remaining on the surface of the photothermographic material, the image forming solvent is surely enclosed in the scratch on the surface of the photothermographic material. It will be in the state of being. Therefore, the transmitted light of the photothermographic material passes through the photothermographic material more reliably without being affected by scratches, so that high-quality image data can be obtained more reliably.

By the way, as the above-mentioned photothermographic material and processing sheet, the following materials can be used.

That is, the photothermographic material comprises at least a photosensitive silver halide, a binder, and a coloring material having a function of releasing or diffusing a diffusible dye imagewise on a support, A color material-containing photothermographic material having at least three types of photosensitive layers having different hues after development of the color material. Further, the processing sheet is used to form an image on the color material-containing photothermographic material by heating the color material-containing photothermographic material in a superimposed manner, and at least a mordant on the support. It is a mordant-containing treatment sheet having a layer containing.

By superimposing and heating these color material-containing photothermographic materials and mordant-containing processing sheets, the diffusible dye is released or diffused in an image form from the color material, and a part of the diffusible dye or The whole is removed from the color material-containing photothermographic material. As a result, a color image of at least three colors is formed on the color material-containing photothermographic material.

Alternatively, as the photothermographic material,
On a support, at least three types of photosensitive layers containing at least a photosensitive silver halide, a binder, and a dye-donor coupler, and having different wavelength regions and hues of dyes formed from the dye-donor coupler are provided. A photothermographic material containing a coupler. The processing sheet is a heat-developable processing sheet used for forming an image on the coupler-containing heat-developable light-sensitive material by heating it in combination with the coupler-containing heat-developable light-sensitive material.

By superimposing and heating the coupler-containing photothermographic material and the heat-developable processed sheet, at least three color images are formed on the coupler-containing photothermographic material by the dye-donating coupler. To be done.

Both ends in the direction are held in a predetermined curved state.

A guide hole 62 is provided in the slide holding portion 46 for holding the processing sheet cassette 42, and a guide pin 64 fixedly provided in the main body 12 is inserted therein. As a result, the slide holder 46 is slidable in the direction in which the main body 12 is brought into contact with and separated from the heating drum 38 while holding the processing sheet cassette 42. Further, the slide holding portion 46 has a guide hole 62.

The feeding portion of is pressed against the outer circumference of the heating drum 38. Therefore, in this state, the film N sent out from the water application unit 24 can be nipped and conveyed between the heating drum 38 and the feeding portion of the processing sheet 58.

The slide holding portion 46 (processing sheet cassette 42) is separated from the heating drum 38 by driving the pinion 68 when the temperature of the heating drum 38 is adjusted (for example, when the temperature is raised). It is like this.

On the other hand, a peeling claw 70 is arranged near the upper part of the heating drum 38. The peeling claw 70 holds the film N nipped and conveyed between the heating drum 38 and the processing sheet 58.
Can be separated from the heating drum 38.

A plurality of conveying rollers 72 are provided in the vicinity of the peeling claw 70, and the film N peeled from the heating drum 38 by the peeling claw 70 is further conveyed to the upper corner portion of the main body 12. It is a configuration that can be sent to the reading unit 76 provided.

Next, the structure of the reading unit 76 will be described with reference to FIGS. 3 (A) and 3 (B). FIG. 3A shows a view of the reading unit 76 from a direction perpendicular to the transport direction of the film N indicated by the arrow B.

Conveying rollers 78 and 80 are arranged in the reading section 76, and the position between the conveying rollers 78 and 80 is the image reading position E. These transport rollers 78 and 80 can further transport the film N separated from the heating drum 38 and transported by the plurality of transport rollers 72 to the reading position E as described above.

A transparent glass plate 82 is arranged at the reading position E between the transport rollers 78 and 80.
The transparent glass plate 82 is located near the side of the transport path of the film N, and is adapted to be pressure-bonded (superposed on the film N) to the film N transported to the reading position E during image reading.

In this case, since the film N is coated with water by the water coating section 24 to the extent that water remains on the surface even after the development processing, as described above, at the reading position E. When the transparent glass plate 82 is pressure-bonded to the film N, if a scratch or the like is present on the surface of the film N, water is sealed in the scratch.

The reading section 76 is provided with a light source 84 for emitting light toward the reading position E, and for preventing unevenness in the amount of light on the downstream side in the light emitting direction (arrow L direction). The mirror box 86 and the diffusion plate 88 are arranged in order.

Further, a lens 90 is arranged on the downstream side of the transport path of the film N, and a CCD sensor 92 for reading a transmitted image by the light transmitted through the film N is arranged on the further downstream side. ing. Lens 90
Has a function of forming an image of the light transmitted through the film N on the CCD sensor 92.

As shown in FIG. 3 (B), the CCD sensor 92 is a B color component reading section 92B composed of a line sensor for reading the B color component of the image, and a G color composed of a line sensor for reading the G color component. An R color component reading unit 9 including a component reading unit 92G and a line sensor that reads the R color component.
It is composed of 2R, and it is possible to digitally read an image by light transmitted through the film N passing through the reading position E line by line for each color component.

Such a CCD sensor 92 is shown in FIG.
As shown in (A), it is connected to a developing / reading control unit 94 that includes a microcomputer and controls various processes of the photosensitive material processing apparatus 10. The developing / reading control unit 94 reads the image data of each color component. Send to. The developing / reading control section 94 is provided with a floppy disk drive 96 and is further connected to a magnetic disk device 98. In the developing / reading control section 94, the received image data is subjected to a predetermined image processing, and then the floppy disk 1 set in the floppy disk drive 96.
00 or the magnetic disk device 98 can store image data. Further, the image data once stored can be read out.

Next, the operation of the present embodiment will be described. In the photosensitive material processing apparatus 10 having the above-described configuration, the processing sheet 5 is previously stored in the processing sheet roll 48 of the processing sheet cassette 42.
8 is wound into a roll and accommodated therein, and further, the processing sheet 58 is unwound from the processing sheet roll 48 and wound around the winding roller 52 and the winding roller 54, and then the front end portion thereof is a winding roller. Locked at 50. In this state, the processing sheet cassette 42 is loaded on the slide holding portion 46 of the main body 12.

In this case, even if the processing sheet cassette 42 is removed from the main body 12, the processing sheet 58 is
The feeding portion (between the winding roller 52 and the winding roller 54) is held in a predetermined curved state by the holding projection 60, so that the processing sheet 58 is not necessary when the processing sheet cassette 42 is attached to or detached from the main body 12. There is no slack or tension.

Next, the operator loads the cartridge 20 in which the film N having the image recorded on each frame is stored in the cartridge loading section 18 of the photosensitive material processing apparatus 10 and operates a start button (not shown). As a result, the heat development processing of the film N is started.

In this case, the processing sheet cassette 42 (slide holding portion 46) is driven by the pinion 68 until the heating drum 38 reaches a predetermined temperature.
Separated from Therefore, unnecessary heating of the processing sheet 58 is prevented.

When the heating drum 38 reaches a predetermined temperature,
The processing sheet cassette 42 is driven by driving the pinion 68.
The (slide holding portion 46) is moved closer to the heating drum 38, and the feeding portion of the processing sheet 58 between the winding roller 52 and the winding roller 54 fed from the processing sheet roll 48 is located on the outer periphery of the heating drum 38. Pressed (in the state shown in FIG. 1).

In this case, even if the processing sheet 58 (processing sheet cassette 42) is separated from the outer circumference of the heating drum 38, the feeding portion of the processing sheet 58 (wrapping roller 5).
Between the two and the wrapping roller 54) is held in a predetermined curved state by the holding projection 60 as described above, so that the processing sheet 58 is not unnecessarily loosened or strained. Therefore, when the processing sheet cassette 42 is moved closer to the heating drum 38, the processing sheet 58 is surely pressed against the heating drum 38.

Then, the drawing and feeding of the film N is started, and the film N is drawn out from the cartridge 20. The film N pulled out from the cartridge 20 passes through the coating tank 26 of the water coating section 24 and is coated with water.
In this case, the film N is sufficiently coated with water so that water remains on the surface even after the development process is completed.

Film N thus coated with water
Are guided between the lower end of the heating drum 38 and the winding roller 52. Further, the film N is wound on the winding roller 52.
While being sandwiched between the processing sheet 58 wound around the heating drum 38 and the outer peripheral portion of the heating drum 38, the outer peripheral portion of the heating drum 38 is conveyed clockwise in FIG. At this time, the processing sheet 58 is also conveyed at the same conveyance speed as the film N. Here, since the film N is coated with water, the film N and the processing sheet 58 are conveyed on the outer peripheral portion of the heating drum 38 in a state of closely contacting each other without a gap.

The leading end of the film N is the heating drum 3
When the heating range in the outer peripheral portion of No. 8 is reached, the film N
The conveyance of the processing sheet 58 is temporarily stopped, and the film N
And the processing sheet 58 is heated for a predetermined time.

Here, the film N is heated while being superposed on the treatment sheet 58, so that the film N
The diffusible dye is released or diffused in an image form from the coloring material contained in the film N, and a part or all of the diffusible dye is removed from the film N. As a result, a color image of at least three colors is formed on the film N. Since water is attached to the film N as described above, the film N is uniformly heat-developed.

When the heating for a predetermined time is completed, the film N
Then, the conveyance of the processing sheet 58 is restarted.

The film N is sandwiched between the processing sheet 58 and the heating drum 38 as described above, the conveyance of the film N is temporarily stopped, and the entire film N is thermally developed at one time. The N may be heat-developed by continuously heating the N while being nipped and conveyed between the processing sheet 58 and the heating drum 38 at a constant speed. When the film N is nipped and conveyed at a constant speed in this manner, each frame image of the film N is heated for the same time, and thermal development can be successfully performed without causing uneven development. Further, if the heat development is performed in this manner, it is not necessary to make the heating range of the heating drum 38 large enough to cover the entire film N, and the conveyance of the film N and the treatment sheet 58 is temporarily stopped or restarted. There is no need to do it.

After the transport of the film N and the treatment sheet 58 is restarted, when the film N and the treatment sheet 58 are transported to the upper end portion of the heating drum 38, the treatment sheet 58 is wound around the winding roller 54. The film N is separated from the film N and is sequentially wound around the winding roller 50. On the other hand, the film N reaching the winding roller 54 is peeled from the heating drum 38 by the operation of the peeling claw 70.
The film N peeled from the heating drum 38 is conveyed by the conveying roller 72 toward the take-out port 74, and is conveyed from the take-out port 74 to the reading unit 76.

In the reading section 76, when the first frame of the film N reaches the reading position E shown in FIG. 3A, the film N is pressure-bonded to the transparent glass plate 82 (the transparent glass plate 8).
2). Here, as described above, since the water is applied to the film N by the water application unit 24 to such an extent that the water remains on the surface even after the development processing, the surface of the film N is temporarily scratched. If there is such a thing, it will be in the state where water was enclosed in this wound.

Then, the film N is irradiated with the light from the light source 84, and the image of the first frame is read by the CCD sensor 92. That is, the transmitted light emitted from the light source 84 and transmitted through the first frame of the film N is focused on the reading surface of the CCD sensor 92 by the lens 90, and the image recorded on the frame is imaged. The image formed here is shown in FIG.
B color component reading unit 92B and G color component reading unit 9 shown in FIG.
The 2G and R color component reading unit 92R reads each color component.

In this case, the film N is the transparent glass plate 82.
The surface of the film N is apparently smooth because the water is enclosed by being superposed on the film N. Here, since the light refractive index of water is closer to that of the film N than that of air, the transmitted light of the film N passes through the film N without being substantially affected by surface scratches. Therefore, it is possible to obtain high-quality image data that is not affected by scratches or the like.

Further, as described above, the CCD sensor 9
The image reading data read in 2 is taken in by the development reading control unit 94, and the taken-in image data is stored in a storage medium (magnetic disk device 98, floppy disk 100, etc.) loaded in a predetermined or designated drive. After that, reading of frame images and storage of image data are successively executed for each frame image of the film N.
Then, when the execution is completed for all the frame images, the control routine ends.

By the image forming process and the reading process in the photosensitive material processing apparatus 10 described above, the image of each frame of the film N is formed and digitally read, and then the image data is stored in the floppy disk 100.

After that, an image based on the image data of each frame stored in the floppy disk 100 is printed by a digital printer (not shown).

As described above, according to the photosensitive material processing apparatus 10 according to the present embodiment, the film N on which an already exposed image (photographed image) is formed by heating.
By using a treated sheet 58 having a layer containing a mordant for developing the film N on a support,
An image can be easily formed by heat development processing without performing complicated development, bleaching, and fixing processing as in the past.

Further, in the light-sensitive material processing apparatus 10, since water as an image forming solvent is applied to the film N before the film N and the processing sheet 58 are superposed on each other, the diffusible dye easily diffuses, and The process of forming an image on N can be performed more effectively.

Further, in the light-sensitive material processing apparatus 10, when the image of the film N after thermal development is read by the reading unit 76, the film N is superposed on the transparent glass plate 82 to be in a water-sealed state. Since light is emitted in this state and image data is obtained by the transmitted light, the transmitted light of the film N passes through the film N without being substantially affected by surface scratches. . Therefore, it is possible to obtain high-quality image data that is not affected by scratches or the like.

As described above, when the image on the film N is photoelectrically read, the influence of scratches or dust is reduced, so that good quality image data can be obtained even if a directional light source is used as the light source 84 for illumination. Therefore, it is possible to use a low-output light source without reducing the light quantity without the need for a diffusion plate. Therefore, it is possible to reduce the cost and the size by reducing the power consumption and the power consumption. .

In the above embodiment, the image data of each frame of the film N is temporarily stored in the floppy disk 100 in the photosensitive material processing apparatus 10, and the image data is read from the floppy disk 100 in the digital printer to read the image data. Although an example of printing an image based on data is shown, the present invention is not limited to this, and the image data may be stored in another storage medium such as a magnetic tape, a magneto-optical disk (MO), or a CD-ROM. A digital printer may be directly connected to the photosensitive material processing device 10 via a signal line or the like, and image data may be directly transmitted from the photosensitive material processing device 10 to print an image.

Further, in the above embodiment, the CCD sensor 92 composed of three line sensors is used to read the image of the film N, but the present invention is not limited to this, and the CCD area for reading the image two-dimensionally is used. A sensor may be used.

Further, in the present embodiment, water as the image forming solvent is applied to the film N, but it may be applied to the treatment sheet 58, or both the film N and the treatment sheet 58. It may be applied to.

Further, in the above-mentioned embodiment, the example in which the color material-containing photothermographic material of the present invention is used as the film N is shown. However, at least a photosensitive silver halide is provided on the support.
Using the coupler-containing photothermographic material of the present invention, which comprises a binder and a dye-donating coupler, and has at least three types of light-sensitive layers in which the light-sensitive wavelength region and the hue of the dye formed from the dye-donating coupler are mutually different Is also good.

The form of the film N may be a normal cartridge type or a form corresponding to an advanced photo system (APS) capable of recording magnetic information.

[0075]

As described above, according to the present invention,
Even when a directional light source is used as a light source for illumination when photoelectrically reading an image on a photosensitive material, the effect of scratches and dust adhesion is small, which eliminates the need for heat measures, reduces power consumption, and reduces costs. An excellent effect that the size can be reduced can be obtained.
