TECHNICAL FIELD OF THE INVENTION
The present invention relates to a photosensitive material processing method for forming an image on a photothermographic material which is developed by heating, and more specifically, an image is formed on the photothermographic material by superposing and heating the photothermographic material. The present invention relates to a photosensitive material processing method for forming an image using a processing sheet to be formed.
[0002]
[Prior art]
In a method known as conventional color photography, a photographic light-sensitive material (a so-called color negative film) is usually a layer that records blue light to form a yellow dye image, and a layer that records green light to form a magenta dye image. And a layer that records a red light to form a cyan dye image. During the development processing, the developer is oxidized in the process of reducing the silver halide particles containing the latent image to silver, and the oxidized product and the coupler are oxidized. (Coupling) to form a dye image. Undeveloped silver halide and developed silver are removed in the subsequent bleach-fixing step to obtain a color negative film from which a dye image has been formed and from which undeveloped silver halide and developed silver have been removed.
[0003]
Heretofore, a color paper has been obtained by irradiating the color paper with light transmitted through the dye image of the color negative film, printing and exposing the dye image to the color paper, and performing the same development, bleaching and fixing steps.
[0004]
On the other hand, there is also known a method in which an image formed on the color negative film is photoelectrically read, subjected to image processing to obtain image data for recording, and an image is obtained on another image recording material by using the image data. In particular, digital printers have been developed in which the above-mentioned image data is converted into digital signals, and a photosensitive material such as color paper is scanned and exposed by a laser beam modulated in accordance with the digital signals to produce a finished print. No., published in US Pat.
[0005]
By the way, in the above-described method, when an 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 or dust attached to the color negative film. However, such a diffusion light source needs to have a high output in order to prevent a decrease in light amount. For this reason, it is necessary to take measures against heat, and it is difficult to reduce power consumption, reduce costs, and reduce the size. Therefore, measures for this purpose have been desired.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above facts, and when reading an image of a photosensitive material photoelectrically, even if a directional light source is used as a light source for illumination, the influence of adhesion of scratches and dust is small, and It is another object of the present invention to provide a photosensitive material processing method which requires no heat countermeasures, consumes less power, can be reduced in cost, and can be made smaller.
[0007]
[Means for Solving the Problems]
The photosensitive material processing method according to the first aspect of the present invention includes exposing an image to a photothermographic material that is developed by heating, heating the exposed photothermographic material and the photothermographic material in a superimposed manner. At least one of the processing sheets used for forming an image on the photothermographic material is coated with a predetermined image forming solvent, and the photothermographic material after the image forming solvent is coated And the processing sheet are superimposed, and by heating the superposed photothermographic material and the processing member, the photothermographic material is developed to form the exposed image. The photothermographic material is separated from the processing sheet, and the photothermographic material separated from the processing sheet by the separation is irradiated with light while the applied image forming solvent remains on the surface. Shines reading the transmitted image obtained by the transmitted light, it is characterized in that.
[0008]
In the photosensitive material processing apparatus according to the present invention, an image is formed on the photothermographic material by superposing and heating the photothermographic material to which the image has been exposed and heating the photothermographic material. A predetermined image forming solvent is applied to at least one of the processing sheets. Incidentally, in the usual case, water is used as a solvent for image formation.
[0009]
After the image forming solvent is applied, the photothermographic material is heated while being superposed on the processing sheet. Here, since the processing sheet is a member used for forming an image on the photothermographic material by being superimposed on the photothermographic material and heating, the superposed photothermographic material and the processing sheet are By heating, the photothermographic material is developed and an exposed image is formed.
[0010]
Further, the photothermographic material on which an image has been formed as described above is peeled off from the processing sheet, and the applied image forming solvent remains on the surface of the photothermographic material separated from the processing sheet by peeling. In this state, light is irradiated to read a transmitted image by the transmitted light.
[0011]
In this case, when the photothermographic material is irradiated with light to read a transmitted image 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 a flaw or the like, the solvent for image formation enters (resides) in the flaw, 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 air, the transmitted light of the photothermographic material passes through the photothermographic material substantially without being affected by scratches. I do. Therefore, high-quality image data free from the influence of scratches and the like can be obtained.
[0012]
As described above, when the image of the photothermographic material is photoelectrically read, the influence of the attachment of scratches and dust is reduced, so that high-quality image data can be obtained even when the directional light source is used as the illumination light source. Therefore, no heat countermeasures are required, the power consumption is low, the cost can be reduced, and the size can be reduced.
[0013]
According to a second aspect of the present invention, in the photosensitive material processing method according to the first aspect, the image forming solvent is applied to the photothermographic material separated from the processing sheet by the peeling. The transparent member is overlapped while remaining on the surface, and light is irradiated in the overlapped state to read a transmitted image by the transmitted light.
[0014]
In the photosensitive material processing apparatus according to the second aspect, the transparent member is superimposed on the photothermographic material while the applied image forming solvent remains on the surface, and light is irradiated in the superimposed state. The transmitted image by the transmitted light is read.
[0015]
In this case, since the transparent member is overlapped with the image forming solvent remaining on the surface of the photothermographic material, it is ensured that the image forming solvent is enclosed in the scratch on the surface of the photothermographic material. It becomes. For this reason, the transmitted light of the photothermographic material can more reliably pass through the photothermographic material without being affected by scratches, and high-quality image data can be obtained more reliably.
[0016]
By the way, the following photothermographic materials and processing sheets can be used.
[0017]
That is, the photothermographic material includes, on a support, at least a photosensitive silver halide, a binder, and a color material having a function of releasing or diffusing an imagewise diffusible dye, and includes a photosensitive wavelength region and the color material. Is a color material-containing photothermographic material having at least three types of photosensitive layers having different hues after development. Further, as a processing sheet, used to form an image on the color material-containing photothermographic material by overlapping and heating the color material-containing photothermographic material, at least a mordant on a support It is a mordant-containing treatment sheet having a layer containing the mordant.
[0018]
By superimposing and heating these color material-containing photothermographic materials and the mordant-containing processing sheet, a diffusible dye is released or diffused imagewise from the color material, and a part or all of the diffusible dye is colored. Is removed from the material-containing photothermographic material. As a result, at least three color images are formed on the color material-containing photothermographic material.
[0019]
Alternatively, as a photothermographic material, at least a photosensitive silver halide, a binder, and a dye-donating coupler are included on a support, and the photosensitive wavelength region and the hue of a dye formed from the dye-donating coupler are adjusted. A coupler-containing photothermographic material having at least three different types of photosensitive layers. The processing sheet is a heat development processing sheet used for forming an image on the coupler-containing photothermographic material by overlapping and heating with the coupler-containing photothermographic material.
[0020]
By superposing and heating the coupler-containing photothermographic material and the heat-developable processing sheet, at least three color images are formed on the coupler-containing photothermographic material by the dye-providing coupler.

It has become.
[0027]
Here, the amount of water applied to the film N by the water application unit 24 is set to such an extent that water remains on the surface of the film N even after the film N has been subjected to the development processing described later in detail. Have been.
[0028]
A replenishment tank 32 is disposed below the application tank 26. The replenishment tank 32 is filled with water as an image forming solvent, and is connected to the coating tank 26 via a pipe 34, a pump 36, and the like. Thereby, the water in the replenishment tank 32 can be fed to the application tank 26 by filling, and the water in the application tank 26 can be discharged (returned) to the replenishment tank 32.
[0029]
A heating drum 38 is installed near the downstream side in the transport direction of the water application unit 24. The heating drum 38 is rotatably supported by the main body 12, and is driven to rotate by a drive system (not shown). A halogen lamp 40 is accommodated in the heating drum 38, and the temperature of the heating drum 38 can be raised.
[0030]
On the other hand, a processing sheet cassette 42 is loaded on the side of the heating drum 38, that is, on the main body 12 on the opposite side to the patrone loading section 18. The processing sheet cassette 42 is formed in a box shape by a pair of holding plates 44 arranged in parallel and opposed to each other, and is removably loaded into slide holding portions 46 provided at the upper and lower portions of the main body 12, respectively. I have. Therefore, the processing sheet cassette 42 can be removed from the main body 12 as shown in FIG.
[0031]
In the gap between the pair of holding plates 44 of the processing sheet cassette 42, a processing sheet roll 48 and a winding roller 50 are supported, and further, a winding roller 52 and a winding roller 54 are supported. One of the winding rollers 52 is urged by a spring 56 and serves as a tension adjusting roller.
[0032]
The processing sheet 58 is wound and stored in the processing sheet roll 48. The processing sheet 58 has a layer containing a mordant for developing the film N on a support. 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 the leading end thereof is locked by the winding roller 50.
[0033]
On the holding plate 44 between the winding roller 52 and the winding roller 54, holding projections 60 having a shape corresponding to the curved state of the heating drum 38 are formed, and both ends in the width direction of the feeding portion of the processing sheet 58. Is held in a predetermined curved state.
[0034]
A guide hole 62 is provided in the slide holding portion 46 that holds the processing sheet cassette 42, and a guide pin 64 fixedly provided in the main body 12 enters therein. Thus, the slide holding unit 46 is slidable in the direction in which the inside of the main body 12 comes into contact with and separates from the heating drum 38 while holding the processing sheet cassette 42. A rack 66 is formed in the slide holding portion 46 near the guide hole 62, and a pinion 68 provided on the main body 12 is engaged with the rack 66. For this reason, the pinion 68 is rotated by the driving of a motor (not shown), so that the slide holding unit 46, that is, the processing sheet cassette 42 slides in the direction of coming and coming from the heating drum 38.
[0035]
When the processing sheet cassette 42 held by the slide holding unit 46 is close to the heating drum 38, a portion where a processing sheet 58 is fed out between a winding roller 52 and a winding roller 54 that are fed from a processing sheet roll 48. Are pressed against the outer periphery of the heating drum 38. Therefore, in this state, the film N sent from the water application unit 24 can be pinched and conveyed between the heating drum 38 and the portion where the processing sheet 58 is fed.
[0036]
Further, when the temperature of the heating drum 38 is adjusted (for example, when the temperature is raised), the slide holding unit 46 (the processing sheet cassette 42) is separated from the heating drum 38 by driving the pinion 68 described above. ing.
[0037]
On the other hand, a peeling claw 70 is disposed near the upper portion of the heating drum 38. The peeling claw 70 can peel the film N nipped and transported between the heating drum 38 and the processing sheet 58 from the heating drum 38.
[0038]
Further, a plurality of transport rollers 72 are provided near the peeling claw 70, and the film N peeled from the heating drum 38 by the peeling claw 70 is further transported and provided at the upper corner of the main body 12. This is a configuration that can be sent to the reading unit 76.
[0039]
Next, the configuration of the reading unit 76 will be described with reference to FIGS. FIG. 3A is a view of the reading unit 76 viewed from a direction perpendicular to the transport direction of the film N indicated by the arrow B.
[0040]
In the reading section 76, transport rollers 78 and 80 are arranged, and a position between the transport roller 78 and the transport roller 80 is an 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.
[0041]
A transparent glass plate 82 is disposed at a reading position E between the transport roller 78 and the transport roller 80. The transparent glass plate 82 is located close to the transport path of the film N, and is pressed against the film N transported to the reading position E (superimposed on the film N) at the time of image reading.
[0042]
In this case, as described above, the water is applied to the film N by the water application unit 24 to such an extent that water remains on the surface even after being subjected to the development processing. By pressing the film 82 onto the film N, if there is a flaw or the like on the surface of the film N, water is sealed in the flaw.
[0043]
A light source 84 that emits light toward the reading position E is installed in the reading unit 76, and a mirror box 86 for preventing light amount unevenness is provided on the downstream side in the light emitting direction (the direction of the arrow L). And a diffusion plate 88 are arranged in this order.
[0044]
Further, a lens 90 is disposed downstream of the transport path of the film N, and a CCD sensor 92 for reading a transmitted image by light transmitted through the film N is disposed further downstream. The lens 90 has a function of forming an image of the light transmitted through the film N on the CCD sensor 92.
[0045]
As shown in FIG. 3B, the CCD sensor 92 has a B color component reading unit 92B composed of a line sensor for reading the B color component of the image, and a G color component reading unit composed of a line sensor for reading the G color component. 92G, and an R color component reading unit 92R configured by a line sensor that reads the R color component. An image formed by light transmitted through the film N passing through the reading position E is digitally converted for each color component in line units. Can be read.
[0046]
As shown in FIG. 3A, such a CCD sensor 92 is connected to a development reading control unit 94 which includes a microcomputer and controls various processes of the photosensitive material processing apparatus 10. Each image data is transmitted to the development reading control unit 94. The development reading control unit 94 is provided with a floppy disk drive 96, and is further connected to a magnetic disk device 98. After performing predetermined image processing on the received image data, the development reading control unit 94 can store the image data in the floppy disk 100 set in the floppy disk drive 96 or the magnetic disk device 98. Further, the image data once stored can be read.
[0047]
Next, the operation of the present embodiment will be described.
In the photosensitive material processing apparatus 10 having the above configuration, the processing sheet roll 48 of the processing sheet cassette 42 accommodates the processing sheet 58 wound in advance in a roll shape. After being fed and wound around the winding roller 52 and the winding roller 54, the leading end is locked to the winding roller 50. In this state, the processing sheet cassette 42 is loaded in the slide holding section 46 of the main body 12.
[0048]
In this case, even when the processing sheet cassette 42 is detached from the main body 12, the feeding portion of the processing sheet 58 (between the winding roller 52 and the winding roller 54) is held in a predetermined curved state by the holding projection 60. Since the processing sheet 58 is held, the processing sheet 58 is not unnecessarily loosened or tensioned when the processing sheet cassette 42 is attached to or detached from the main body 12.
[0049]
Next, the operator loads the patrone 20 containing the film N in which an image is recorded in each frame into the patrone loading section 18 of the photosensitive material processing apparatus 10, and operates a start button (not shown). Thus, the thermal development processing of the film N is started.
[0050]
In this case, the processing sheet cassette 42 (slide holding unit 46) is separated from the heating drum 38 by driving the pinion 68 until the heating drum 38 reaches a predetermined temperature. Therefore, unnecessary heating of the processing sheet 58 is prevented.
[0051]
When the temperature of the heating drum 38 reaches a predetermined temperature, the processing sheet cassette 42 (slide holding unit 46) is moved closer to the heating drum 38 by driving the pinion 68, and is wound around the winding roller 52 drawn out of the processing sheet roll 48. The feeding portion of the processing sheet 58 between the roller 54 and the roller 54 is pressed against the outer periphery of the heating drum 38 (the state shown in FIG. 1).
[0052]
In this case, even if the processing sheet 58 (processing sheet cassette 42) is separated from the outer periphery of the heating drum 38, the feeding portion of the processing sheet 58 (between the winding roller 52 and the winding roller 54) is the same as described above. The processing sheet 58 is held in a predetermined curved state by the holding projection 60, so that the processing sheet 58 is not unnecessarily loosened or tensioned. Therefore, when the processing sheet cassette 42 is moved closer to the heating drum 38, the processing sheet 58 is reliably pressed against the heating drum 38.
[0053]
Next, the drawing-out conveyance of the film N is started, and the film N is pulled out from the cartridge 20. The film N drawn from the patrone 20 passes through the inside of the application tank 26 of the water application section 24, and is coated with water. In this case, the film N is sufficiently coated with water to such an extent that water remains on the surface even after the development processing is completed.
[0054]
The film N coated with water in this manner is guided between the lower end of the heating drum 38 and the winding roller 52. Further, the film N is conveyed clockwise in FIG. 1 around the outer periphery of the heating drum 38 while being sandwiched between the processing sheet 58 wound around the winding roller 52 and the outer periphery of the heating drum 38. At this time, the processing sheet 58 is also transported at the same transport speed as the film N. Here, since water is applied to the film N, the film N and the processing sheet 58 are conveyed along the outer peripheral portion of the heating drum 38 in a state where the film N is in close contact with no gap.
[0055]
When the leading end of the film N reaches the heating range in the outer peripheral portion of the heating drum 38, the conveyance of the film N and the processing sheet 58 is temporarily stopped, and the film N and the processing sheet 58 are heated for a predetermined time.
[0056]
Here, when the film N is heated in a state of being superposed on the processing sheet 58, the diffusible dye is released or diffused in an image form from the color material contained in the film N, and a part or all of the diffusible dye is Is removed from the film N. Thereby, at least three color images are formed on the film N. Since water adheres to the film N as described above, the film N is uniformly heat-developed.
[0057]
When the heating for the predetermined time is completed, the conveyance of the film N and the processing sheet 58 is restarted.
[0058]
In addition to temporarily stopping the conveyance of the film N while holding the film N between the processing sheet 58 and the heating drum 38 as described above, the film N Thermal development may be performed by continuously heating the sheet 58 and the heating drum 38 while nipping and conveying the sheet 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, so that thermal development can be successfully performed without causing uneven development. Further, if the heat development is performed in this manner, the heating range of the heating drum 38 does not need to be configured to be large enough to cover the entire film N, and the conveyance of the film N and the processing sheet 58 is temporarily stopped or restarted. Or the need to
[0059]
After the conveyance of the film N and the processing sheet 58 is resumed, when the film N and the processing sheet 58 are conveyed to the upper end portion of the heating drum 38, the processing sheet 58 is wound around the winding roller 54 so that the film N , And are sequentially taken up by the take-up roller 50. On the other hand, the film N that has reached the winding roller 54 is separated from the heating drum 38 by the operation of the separation claw 70. The film N peeled off from the heating drum 38 is transported by the transport roller 72 toward the outlet 74, and is transported from the outlet 74 to the reading unit 76.
[0060]
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 pressed against the transparent glass plate 82 (overlaid on the transparent glass plate 82). Here, as described above, since water is applied to the film N by the water application unit 24 to such an extent that water remains on the surface even after the development processing, the surface of the film N is temporarily damaged. The presence of water and the like results in a state in which water is sealed in the wound.
[0061]
Next, the light from the light source 84 is applied to the film N, 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 forms an image recorded on the frame. The image formed here is read for each color component by a B color component reading unit 92B, a G color component reading unit 92G, and an R color component reading unit 92R shown in FIG.
[0062]
In this case, the film N is superimposed on the transparent glass plate 82 so that water is sealed therein, so that the surface of the film N is apparently smooth. Here, water has a light refractive index closer to that of the film N than air, so that light transmitted through the film N passes through the film N in a state substantially free from surface damage. Therefore, high-quality image data free from the influence of scratches and the like can be obtained.
[0063]
Further, the image data read by the CCD sensor 92 as described above is fetched by the development reading control unit 94, and is stored in a storage medium (such as the magnetic disk device 98 or the floppy disk 100) mounted on a predetermined or designated drive. The captured image data is stored. Thereafter, the reading of the frame image and the storage of the image data are successively executed for each frame image of the film N. When the execution has been completed for all the frame images, the control routine ends.
[0064]
After the image of each frame of the film N is formed and read digitally by the image forming process and the reading process in the photosensitive material processing apparatus 10 described above, the image data is stored in the floppy disk 100.
[0065]
Thereafter, an image based on the image data of each frame stored in the floppy disk 100 is printed by a digital printer (not shown).
[0066]
As described above, according to the photosensitive material processing apparatus 10 according to the present embodiment, the film N in which the already exposed image (the photographed image) is formed by heating is developed on the support. By using the processing sheet 58 having a layer containing a mordant for the development, an image can be easily formed by heat development processing without performing complicated development, bleaching and fixing processing as in the related art.
[0067]
Further, in the photosensitive 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 overlaid, the diffusible dye is easily diffused, and Can be more effectively performed.
[0068]
Further, in the photosensitive material processing apparatus 10, when the image of the film N after the thermal development is read by the reading unit 76, the film N is superimposed on the transparent glass plate 82 so that water is sealed therein. In this state, light is emitted and image data is obtained by the transmitted light, so that the transmitted light of the film N passes through the film N without being substantially affected by surface scratches. Therefore, high-quality image data free from the influence of scratches and the like can be obtained.
[0069]
Further, as described above, when the image of the film N is photoelectrically read, the influence of the attachment of scratches and dust is reduced, so that high-quality image data can be obtained even when a directional light source is used as the light source 84 for illumination. Thus, a diffuser plate or the like is not required, so that a low-output light source can be used without a decrease in light quantity. Therefore, heat measures are unnecessary, power consumption is reduced, cost can be reduced, and downsizing can be achieved.
[0070]
In the above-described 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 digital printer reads the image data from the floppy disk 100 and performs processing based on the image data. Although an example of printing an image has been described, the present invention is not limited to this, and image data may be stored in another storage medium such as a magnetic tape, a magneto-optical disk (MO), or a CD-ROM. Alternatively, 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 transmitted directly from the photosensitive material processing device 10 to print an image.
[0071]
In the above embodiment, the image of the film N is read by using the CCD sensor 92 composed of three line sensors. However, the present invention is not limited to this, and a CCD area sensor that reads the image two-dimensionally is used. May be.
[0072]
Furthermore, in the present embodiment, water as an image forming solvent is applied to the film N, but may be applied to the processing sheet 58 or may be applied to both the film N and the processing sheet 58. May be.
[0073]
Further, in the above embodiment, an example was shown in which the color material-containing photothermographic material of the present invention was used as the film N, but at least a photosensitive silver halide, a binder, and a dye-donating coupler were provided on a support. And the coupler-containing photothermographic material of the present invention having at least three types of photosensitive layers having different photosensitive wavelength regions and different hues of the dye formed from the dye-donating coupler.
[0074]
The film N may be of a normal patrone type, or may be a form corresponding to an advanced photo system (APS) capable of recording magnetic information.
[0075]
【The invention's effect】
As described above, according to the present invention, when an image on a photosensitive material is photoelectrically read, even if a directional light source is used as a light source for illumination, the influence of adhesion of scratches and dust is small, whereby An excellent effect is obtained that measures are not required, power consumption is low, cost can be reduced, and miniaturization can be achieved.
