Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a photograph creation device that is most suitable for quickly processing a photographed image of a person or the like to obtain a photograph, such as an ID photograph.

[Conventional technology]

2. Description of the Related Art A photo production device using a diffusion transfer method has been proposed as a photo taking device for taking images of people to be pasted on driver's licenses, passports, etc. (see Japanese Patent Laid-Open No. 193824/1999).

In this photographic production device, an image of a person is exposed onto a heat-developable photosensitive material, an image-forming solvent is attached to the photosensitive material, the photosensitive material is brought into close contact with an image-receiving material, and development and transfer is performed. The image-receiving material is made into a product by peeling the materials from each other. For this reason, this photographic production apparatus can obtain photographs in a short time with a more compact structure than a general photographic production apparatus which uses a conventional negative film, develops it, and then prints it onto photographic paper to develop a positive image.

In such photographic production equipment, water is used as an example of an image forming solvent applied to the photosensitive material, but this water is pumped out from a storage tank and reaches the water application section, causing bubbles to form in the water. When the image forming solvent easily passes through water, these bubbles may adhere to the surface of the image forming solvent. These bubbles cause poor adhesion between the photosensitive material and the image-receiving material, causing defects in the formation of images formed on the image-receiving material.

[Problem to be solved by the invention]

SUMMARY OF THE INVENTION In view of the above-mentioned facts, it is an object of the present invention to provide a photographic production apparatus in which bubbles in a solvent are less likely to adhere to a photosensitive material in an area where an image forming solvent is applied.

[Means to solve the problem]

The present invention is a photographic production apparatus that attaches an image-forming solvent to a heat-developable photosensitive material onto which an image has been exposed, then develops the photosensitive material and transfers the image to an image-receiving material, thereby producing the image-receiving material as a product. The image forming apparatus is characterized in that an image forming solvent coating section is provided that allows the image forming solvent to pass in a direction intersecting with the passing direction of the photosensitive material.

Therefore, in the present invention, when the photosensitive material after the image has been exposed passes through the part where the image forming solvent is attached, the image forming solvent is passed in a direction intersecting the passing direction of the photosensitive material. The bubbles inside are difficult to adhere to the surface of the photosensitive material, and the bubbles that have already adhered are peeled off from the photosensitive material in the direction in which the image forming solvent passes. Furthermore, since the direction in which the image forming solvent passes intersects with the direction in which the photosensitive material passes, bubbles in the solvent are not sent downstream in the direction in which the photosensitive material passes.

When replacing the photosensitive material magazine 54, the lid of the storage box 52 is opened.

A nip roller 56 is provided on the downstream side of the photothermographic material P pulled out from the photosensitive material magazine 54 to pull out the photothermographic material P vertically downward by a predetermined length, and a cutter 58 is used to pull out the photothermographic material P vertically downward. The tip is cut to the required length. To the guide plate 60, a non-woven fabric, long fiber paper, cloth, etc., such as a tray sheet made by Toshishima, etc., is attached for the purpose of removing cutting debris generated during cutting.

The cut photothermographic material P is sent out from the storage box 52 by a conveyance roller 59 and sent out to the photographing and exposure section 28.

(Description of Photographic Exposure Section 28) As shown in FIGS. 2 to 4, in the photographic exposure section 28, a pair of guide rods 64 are horizontally extended to a pair of side plates 62, and a movable table 66 is attached to these. guide rod 64
It is possible to move horizontally along the Photographing shutters 68 and 69 are attached to the movable table 66 in parallel and are adapted to selectively correspond to the photothermographic material placed at the photographing position.

These shutters 68 and 69 are for photothermographic material P.
Four optical means 72 and 74 are arranged to respectively expose four portrait images of the photographed person 22. These optical means 72 and 74 have different sizes of human images exposed onto the photothermographic material P.

A screw shaft 70 passes through the carriage 66 in order to selectively align the optical means 72, 74 to the printing position. This screw shaft 70 is rotated by a motor 71 to move the movable table 66 in the horizontal direction. For this reason, the person 22 to be photographed operates a selection button (not shown) depending on the size of the photographed image desired, so that these optical means 72 or 74 can be adapted to the photosensitive material. These optical means 72.
A shutter (not shown) disposed inside 74 is driven by a motor 76.

In front of the optical means 72, 74 (in the direction of the person to be photographed), light guide boxes 78, 82 correspond, respectively.

A pair of conveyor belts 84 and 86 shown in FIG. 2.4 are arranged on the opposite side of the moving platform 66 for the photothermographic material P arranged in the photographic exposure section 28. These conveyor belts 84
．． 86 is an endless belt, which is wound between an upper pulley 88 located near the photosensitive material storage section 26 and a lower pulley 92 located near the entrance of the water application section 32;
It is rotated by the driving force of the motor 94 and applies driving force to the vicinity of both ends in the width direction of the photothermographic material P.

A horizontal roller 96 is pivotally supported at the same height position as the upper pulley 88, and holds the vicinity of both ends of the photothermographic material P in the width direction between it and the conveyor belts 84 and 86.
The photothermographic material P sent out from the photothermographic material P is photographed and exposed at the exposure section 28.
It is designed to generate a conveying force that sends the material to the

The heat-developable photosensitive material P sent to the photographing and exposure section 28 is arranged with its sensitive material side facing the moving stage 66, and as shown in FIG. It is designed to be sandwiched between. This suppression plate 98 is pressed against the movable stage 66 by the biasing force of the compression coil spring 102, and is separated from the movable stage 66 by the operation of the solenoid 104 to form a passage for the photothermographic material P. .

A positioning pin 106 is arranged near the flat end of the pressing plate 98 so as to pass through it with its center horizontally, and the driving force of the solenoid 108 resists the biasing force of the compression coil spring 109 to move the photothermographic material P into the transport path. It can be moved in the axial direction. Therefore, when these positioning pins 106 protrude into the transport path of the photothermographic material P, the photothermographic material P receives the driving force from the upper pulley 88 and the horizontal roller 96 and falls naturally after passing between them. At this point, the lower end comes into contact with the positioning pin 106 and the lowering operation is stopped, thereby ensuring accurate positioning at the burning position.

A horizontal roller 102 is arranged near the positioning pin 106 corresponding to the intermediate portion of the conveyor belt 84, 86, and the photothermographic material P after image printing is held between it and the conveyor belt 84, 86 and lowered. It is designed to provide driving force.

After the image is taken, the photothermographic material P falls freely due to the retraction of the positioning pin 106, and its lower end touches the horizontal roller 1.

As shown in FIG. 3, this frame exposure section 30 has frame exposure openings 114 and 116 formed in a part of a movable table 66, and a helices film 118 fixed thereto. This lithographic film 118 is provided with a light shielding part 122 corresponding to the exposed image area, and a blank part 124 is provided around the light shielding part 122 . Therefore, when this lithographic film 118 is exposed to light by a strobe light emitting means (not shown), the periphery of the photographed person image is exposed, and the periphery of the image as a product can be made white.

(Description of Vertical Guide Section) The photothermographic material P after frame exposure has been completed in the frame exposure section 30 is guided to the water coating section 32 through the vertical guide section 31 . In the vertical guide portion 31, a guide plate 132 is arranged corresponding to the vertical portion of the conveyor belt 84, 86. This guide plate 132 and the conveyor belt 84.8
There is no contact between the photothermographic material P and the photothermographic material P, and the distance therebetween is sufficient to allow the photothermographic material P to fall freely.

Therefore, when the photothermographic material P on which the image has been photographed is removed from between the horizontal roller 112 and the conveyor belts 84 and 86, it falls freely on the vertical guide section 31, and then moves to the positioning roller 134 disposed below the guide plate 132. and conveyor belt 84.86
The lower end comes into contact between the two and stops.

Therefore, the heat-developable photosensitive material P after photographing quickly descends within this vertical guide section 31.

Note that the conveyor belts 84 and 86 move at a conveyance speed slower than the rate at which the photosensitive material E falls under its own weight, thereby preventing the photosensitive material from clogging the vertical guide section 31.

The positioning roller 134 is a free roller whose axis is horizontal, and its outer periphery is in contact with the conveyor belts 84 and 86. Therefore, the lower end of the free-falling photothermographic material P is held between the positioning roller 134 and the conveyor belts 84 and 86, and is sent downward onto the guide plate 136, which is arranged at an angle with respect to the vertical direction. The water is sent to the water application section 32 by sliding on the surface.

As shown in FIG. 5, a sensor 137 is provided at the outlet of the water application section 32, and the sensor 137 detects the photosensitive material after a predetermined period of time has passed since the photosensitive material begins to fall under its own weight due to the rotation of the horizontal roller 112 (FIG. 4). If E is not detected by this sensor 137, error processing is performed.

(Description of the water application part) As shown in Fig. 5.6, in the water application 832, the guide plate 1

The photothermographic material P sent out from these nipping rollers 142 is sent between an upper guide plate 144 and a lower guide plate 146 that are arranged parallel to each other. The lower guide plate 146 is integrally connected to the lower end of the guide plate 136. The upper guide plate 144 and the lower guide plate 146 are bent at the downstream side in the conveyance direction of the photothermographic material P, so that the photothermographic material P is bent into a substantially arc shape and guided obliquely upward. Therefore, these upper guide plates 144 and lower guide plates 146 have a dish-shaped cross section as shown in FIG. It serves as a water storage section 148.

End plates 152 are provided at both ends of the upper guide plate 144 and the lower guide plate 146 in the direction perpendicular to the transport direction of the photothermographic material P.
．． 154 are fixed to each other to prevent water from flowing out from the water storage portion 148. One end of a pipe 156 passes through the end plate 152 . As shown in FIG.
62.

A saucer 164 is disposed below the downstream ends of the upper guide plate 144 and the lower guide plate 146, with the upper ends open. Therefore, water overflowing from the downstream end of the lower guide plate 146 is stored in this saucer 164, and the water that overflows from the downstream end of the lower guide plate 146 is stored in
6 to be returned to the tank 158.

The direction in which water is supplied to the water storage section 148 through this piping 156 intersects at right angles with the conveyance direction (direction of arrow B) of the photothermographic material P, as shown by arrow A in FIG. The air bubbles attached to the photothermographic material P are removed, and the air bubbles in the water in the water storage section 148 are prevented from adhering to the photothermographic material P. Further, air bubbles are not sent to the downstream side in the conveyance direction of the photosensitive material P.

This water supply direction (six directions of arrows) does not necessarily have to be perpendicular to the direction of conveyance of the photosensitive material P, but may be any direction that intersects with the direction of conveyance of the photosensitive material.

A pair of conveyance rollers 168 are disposed at the exit of the water application section 32, and are adapted to send the water-coated photothermographic material P obliquely upward and into the heat development section 36 through a pair of guide plates 169. ing.

As shown in FIG. The image receiving material R whose leading end is pulled out from the image receiving material magazine 172 passes through a reversing roller 188 and then passes through a nip roller 17.
The paper is cut into a predetermined length by a cutter 176 after being subjected to a clamping and conveying force at 4. If the nip roller 174 is constantly in contact with the image-receiving material, it may leave roller marks, so it is designed to be nipped only during conveyance, and its operation timing is controlled by a controller.

A pair of conveyance rollers 178 are arranged downstream of the cutter 176, and are adapted to sandwich the cut image-receiving material R and send it to the thermal development section 36 through a pair of guide plates 182 and 184. . The guide plate 184 is pasted with non-woven fabric, long fiber paper, cloth, etc., such as paper towels, etc., in order to remove dust adhering to the surface of the image-receiving material. The direction in which the image receiving material R of these guide plates 182 and 184 is conveyed is diagonally downward, and is bonded to the photothermographic material P fed diagonally upward from the water coating section 32 at an angle θ and is heated. It is designed to be sent to a developing section 36.

While drawing, the image is reversed so that the image plane faces upward, and the image is sent to the conveyance direction changing section 46. As shown in FIG. 1, this reversing guide section 44 is disposed close to the partition wall 18 that separates the photographing room 14 and the photographic production room 16, and is arranged to move the dried image-receiving material R onto an extension of the peeling section 38. This eliminates the need for an increase in the space of the photo production room 16 when guiding the camera to the right in FIG.

(Description of Conveyance Direction Changing Unit) As shown in FIGS. 7 to 9, the conveyance direction change unit 46 has a pair of nipping conveyors for horizontally sending out the image-receiving material R that has been reversed and carried out from the reversing guide unit 44. roller 242
is provided. The image receiving material R sent out from these nipping conveyance rollers 242 is transferred between the horizontal support plates 244 and 246 in a direction opposite to the conveyance direction in the peeling section 38 (in the direction indicated by the arrow).

(Description of Dehumidification Device) As shown in FIG. 1, a dehumidification device 302 is provided in the upper part of the photo production room 16. This dehumidification device 302 has a compressor 306 disposed inside a case 304, and a circulation pipe 30.
The refrigerant is circulated within the 8. Circulation pipe 3
08, a condenser 312 is arranged downstream of the compressor 306 and faces the outside air, so that the compressed refrigerant is condensed. An evaporator 316 is arranged downstream of this condenser 312 via an expansion valve 314 . In this evaporator 316, the refrigerant that has passed through the expansion valve 314 expands, absorbs heat from the air in the photographing room 14, and condenses moisture in the air. This condensed water is collected in a tray 318 and sent through a pipe 322 to a tank 158 of the water application section 32. Further, a heater 324 is arranged near the evaporator 316 to raise the cooled air to a predetermined temperature again and return it into the photo-making chamber 16.

As a result, in this dehumidifying device 302, the fan 326 sends the air inside the photo-making chamber 16 to the evaporator 316 to cool it, generate condensed water, and then heat it again to the original temperature or a desired temperature with the heater 324 to make the photo. Since the humidity in the photographic production chamber 16 is always maintained at a predetermined level, the storage performance (
(during menstruation) becomes stable.

The present invention is not limited to the above-mentioned dehumidifying structure, but can be applied to various dehumidifying structures widely used in boat fishing. For example, Nippon Blower's thermocooler ES-1 uses an electronic cooling method.
7FF and thermo cooler ES-32FF are applicable.

[Effect of the embodiment]

The person to be photographed 22 enters the photo creation room 16, takes a seat on the seat 20, and then operates a photographing start button (not shown).

As a result, the photosensitive material magazine 5 of the photosensitive material storage section 26
A photothermographic material P is pulled out from the photothermographic material P by a nip roller 56 and cut into a predetermined length by a cutter 58. The cut heat-developable photosensitive material P is sent to a photographing position through a conveyance roller 59, and is positioned with a positioning pin 106. Further, in order to remove dirt, dust, etc. inside the machine, a dust remover (for example, a filter-type electrostatic precipitator) can be used.

At the same time, in order to correspond to the image size selected by the person to be photographed 22, the motor 71 is activated and the moving table 66 is moved to the optical means 72.
Alternatively, the optical means 74 may be made to correspond to the photographing optical axis. At this point, the photographing shutter is operated and the image of the person in the photographing and exposing section 28 is exposed onto the photothermographic material P.

After exposure, the positioning pin 1 is moved by the operation of the solenoid 108.
06 is withdrawn, the photothermographic material P is transferred to the conveyor belt 84.
．． Frame exposure is performed by being held between the roller 86 and the horizontal roller 112. After that, the photosensitive material P is transferred to the conveyor belt 84.86.
It passes between the guide plate 132 and falls under its own weight and moves quickly. The lower end of the fallen photothermographic material P reaches the point of contact between the positioning roller 134 and the conveyor bell (84, 86) and is prevented from falling freely.

The heat-developable photosensitive material P, which is driven by the positioning roller 134 and sent to the water application section 32 through the guide plate 136, passes through the water storage section 148. The water in the tank 158 is supplied to this water storage section 148 in the direction of the arrow hole by the drive of the pump 162, so the conveying direction of the photothermographic material P intersects with this water supply direction, and the air bubbles in the water are exposed to the photosensitive material. Air bubbles on the photothermographic material P that are difficult to adhere to and are present on the photothermographic material P are also removed. Furthermore, since the air bubbles are not sent to the downstream side in the conveyance direction of the photosensitive material together with the photosensitive material, there is less air bubble adhesion. Further, since the water storage section 148 is provided in a narrow space between the upper guide plate 144 and the lower guide plate 146, the temperature decrease due to heat conduction of the water supplied from the tank 158 while being maintained at a predetermined temperature is small.

The heat-developable photosensitive material P sent out from the water application section 32 is sent out from the image-receiving material storage section 34 and brought into close contact with the image-receiving material R cut into a predetermined length, and then sent to the heat development section 36 . In the thermal development section 36, the photothermographic material P is heated by the heater 202 while passing through the guide plate 198 and reaching the downstream nipping conveyance roller 194, so that the photothermographic material P is thermally developed and the image thereof is transferred to the image receiving material R.

Next, the amount of water applied in the water application section, the clamping force of the clamping conveyance rollers 192 and 194 in the thermal development section 36, and their influence on image deviation and image unevenness will be explained.

If the amount of water applied is small, it will cause poor development of the photosensitive material and weak adhesion to the image-receiving material, causing image unevenness.

Furthermore, if the amount of water applied is large, the photosensitive material and the image-receiving material may shift from each other due to the clamping force, causing image shift.

Furthermore, if the clamping force of the clamping and conveying rollers 192 and 194 is large, it causes image shift.

Table 1 shows these relationships.
'' indicates that a good image is obtained with no image shift and low stain (Dv<0.0 by Maelite densitometer).
3), and the "x" mark indicates a defective image with occurrence of deviation (line blurring when photographing lattice fringes) and high stain.

As is clear from Table 1, the amount of water applied to the photosensitive material must be Log/cnf or more and 20 g/cut or less, and the bonding and clamping pressure must be 2 kg or less.

Next, the bonding angle θ between the photosensitive material P and the image-receiving material R at the entrance of the thermal development section 36 and the nipping conveyance roller 192.
The influence of the clamping pressure caused by No. 194 on image deviation and image unevenness will be explained.

If the bonding angle θ is small, air may enter between them, or bubbles in the applied water may become entangled, resulting in image unevenness. Furthermore, if the clamping pressure is strong, the clamping pressure causes misalignment between the photosensitive material and the image-receiving material, causing image misalignment.

Table 2 shows these relationships.
" mark indicates that there is no image shift or unevenness, and an "x" mark indicates that shift (line blur) or unevenness has occurred. Further, the "△" mark indicates that image unevenness is slightly visible.

As is clear from Table 2, the bonding angle θ between the photosensitive material P and the image-receiving material R must be 30 degrees or more, and the bonding and clamping force must be 2 kg or less.

The heat-developable photosensitive material P and the image-receiving material R sent out from the heat-developing section 36 reach the peeling section 38, where the heat-developable photo-sensitive material P is peeled off from the image-receiving material R. This photothermographic material P is lowered by an endless bell 216, conveyed in the direction of arrow C, and stored in the waste box 41. On the other hand, the image receiving material R is sent out horizontally from the thermal development section 36 and is dried by the hot air heater 228 while moving horizontally on the support table 222 . Therefore, since the image-receiving material R is dried while being conveyed in a straight line, the image-receiving material R does not curl after drying. The image-receiving material R sent out in the horizontal direction from the peeling section 38 passes through the reversing guide section 44 and is reversed upward, and then reaches the conveyance direction changing section 46 .

In the conveyance direction changing section 46, the sheet is sent between the horizontal support plates 244 and 246 in the direction indicated by the arrow. This horizontal support plate 244 and 2
Before the image receiving material R enters between the solenoid 26 and the
6 is activated and the conveyance roller 252 moves to the rotating bracket 254.
They are also retreating upwards. Image receiving material R is horizontal support plate 2
46, power to the solenoid 266 is cut off and the motor 268 is driven. As a result, the conveyance roller 252 that entered through the opening 248 is placed between the image receiving material R and the horizontal support plate 244.
The image-receiving material R is conveyed in a direction (direction of arrow E) perpendicular to the direction in which the image-receiving material R is fed in (arrow direction) and guided to the nipping conveyance rollers 282. The image receiving material R is a guide plate 284,
The product is supplied to the product outlet 48 via the nipping and conveying rollers 286.

Therefore, the product outlet 48 is provided facing the outside of the housing 12 rather than the inside of the photography room 14, and the next operation for the previously photographed person 22 to take out the image receiving material R from the product outlet 48 is as follows. This does not interfere with the photographic person 22 performing photographing work in the photographing room 14.

Further, during the operation of this photographic production apparatus 10, the dehumidifier 302 always maintains the humidity in the photographic production chamber 16 at a predetermined value, so that the thermally developable photosensitive material P and the image receiving material R have improved floating performance and are dehumidified. After that, the condensed water is stored in tank 1 of water application section 32
58 for reuse.

Table 1 Table 2 [Effects of the Invention] Since the present invention has the above structure, bubbles in the solvent are less likely to adhere to the photosensitive material in the image forming solvent coating section, and the image formed on the image receiving material is improved. Quality can be maintained.
