Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a beer-apart type instant photographic device that separates an image-receiving sheet and a photosensitive sheet after development processing.

[Prior art]

BACKGROUND ART Cameras using a beer-apart type instant film unit (hereinafter simply referred to as a film unit) have been widely known. This film unit consists of a photosensitive sheet for recording a latent image and an image receiving sheet for receiving this latent image, and multiple film units are stacked one on top of the other so that these sheets are positioned on both sides of a support plate. It is stored in a flat tire. After loading this puncture into the camera and taking a picture, if you pull out the tab attached to the photosensitive sheet side, the photosensitive sheet will be pulled out while going around behind the support plate, and its tip will be attached to the tip of the image receiving sheet. It protrudes from the camera's film ejection port in a tight state. In this state, the tab will be peeled off, so next time, if you hold the tips of the photosensitive sheet and image-receiving sheet that are in close contact with each other and pull them out, the photosensitive sheet and image-receiving sheet will gradually come into close contact with each other starting from the tips, and slide between the pair of developing rollers. pass. When passing through this developing roller, the developer pod splits open and the developer contained therein is pushed out.
It is developed between a photosensitive sheet and an image receiving sheet. With this developer, the latent image recorded on the photosensitive sheet is transferred to the image-receiving sheet, and an image is formed on this image-receiving sheet.

In the conventional beer apartment type instant photography mentioned above, the number of film units stored in one pan is about 10, so this is not a big problem when used with an amateur camera that takes only a small number of shots.
For commercial purposes that take a large number of photos, such as coin-in type ID photo taking devices, studio photo taking devices, driver's license photo taking devices, C
In RT image photographing devices and the like, there is a problem in that photographing is troublesome because punctures must be replaced frequently. In addition, in order to ensure that the film unit can be pulled out one by one from the pack, a pull-out sheet with a tab is attached to the front edge of the photosensitive sheet, and a transport sheet is attached to the front edge of the image-receiving sheet. Due to this complicated structure, the cost of the film unit was high.

[Purpose of the invention]

An object of the present invention is to provide a beer apartment type instant photographing device that can easily take a large number of photographs and has a simple structure to reduce the cost per photograph. This is the purpose.

[Structure of the invention]

In order to achieve the above object, the present invention uses a roll-shaped member in which each frame is continuous as a photosensitive member for recording an image and an image receiving member for receiving a latent image and forming an image. Afterwards, the photosensitive member and the image receiving member are cut into a sheet for one frame, and the image receiving member and the photosensitive member are brought into close contact with each other before or after cutting, and then the developer pod attached to the image receiving member is split open and developed. The liquid is spread out, developed in the form of a sheet, and then discharged.

Embodiments of the present invention will be described in detail below with reference to the drawings.

〔Example〕

In FIG. 1, a photosensitive member 1 for recording a latent image is wound around a core 2, and is detachably loaded into a core receiver 1) disposed above a camera housing 10. As shown in FIG. This photosensitive member 1 is attached to a guide roller 12. Return roller 13.
It passes through the guide rollers 14 one after another and reaches the exposure position P. The return roller 13 is connected to the rod 15 of the air cylinder 15.
a, and after cutting into sheets, moves forward and returns the leading end of the photosensitive member 1 a little, thereby eliminating waste of the photosensitive member 1. A photographing lens 17 having a lens shutter 16 is disposed in front of the exposure position P, and while the lens shutter 16 is open, an image of the subject is formed on the photosensitive member l and recorded as a latent image thereon. do. In order to prevent external light from entering the photosensitive member 1 at the exposure position P, a bellows 19 is attached to the exposure frame 18 and the photographing lens 17. Further, in order to ensure the flatness of the photosensitive member 1 at the exposure position P, a plate 20 is provided. A pair of photosensitive member feeding rollers 22 and 23 are disposed at the lower end of the exposure frame 18, and are driven by a motor 24 to feed the exposed photosensitive member 1 in a fixed amount until the leading edge of the exposed photosensitive member 1 reaches the photosensitive member leading edge position Pi. conduct.

In order to receive the latent image recorded on the photosensitive member 1 and form an image, the image receiving member 3 is wound around a core 4 and is detachably loaded into a core receiver 26 disposed below the camera housing 10. has been done.

As shown in FIG. 2, the image receiving member 3 includes image receiving sheets 27 and intermediate sheets 28 that are alternately joined.

A developer pod 29 containing a developer is attached to the intermediate sheet 28 by heat sealing or the like. This developer pod 29 has a portion 29a in the center thereof where no developer is accommodated. The image receiving sheet 27
Spacers 30 are bonded to both sides of the developer pod 2 to maintain a constant distance from the photosensitive member 1.
The liquid extruded from 9 is spread out to a certain thickness. A dashed line 31 indicates a cutting line when cutting into a sheet, and this cutting separates the intermediate sheet 28 into a pull-out portion 28a and a skirt portion 28b for receiving excess developer.

The image receiving member 3 is sent out to the image receiving member tip position P2 by a pair of image receiving member feeding rollers 36 and 37 driven by the motor 35. This image receiving roller 36, 37 is
In order to prevent the developer pod 29 from tearing when the image receiving member 3 is pulled out, a narrow width 3 is used as shown in FIG.
It is constructed of two rollers, and avoids the portion of the developer pod 29 where the developer is stored. Since the image receiving member leading end position P2 is located further than the photosensitive member leading end position P1, the image receiving member feeding rollers 36 and 37 are set to have a larger feeding amount than the photosensitive member feeding rollers 22 and 23.

Then, the photosensitive member 1 is stacked on the image receiving member 3, and the adhesive tape 38a is pasted thereon, and then the photosensitive sheet member 1a and the image receiving sheet member 3a are stacked together as shown in FIG.
Then, it is cut with a cutter 39. Instead of this cutter 39, cutters 40, 41 are arranged near the photosensitive member delivery rollers 22, 23 and near the image receiving member delivery rollers 36, 37, respectively, so that the photosensitive member 1 and the image receiving member 3 can be separated from each other. May be cut.

The adhesive tape 38a is used when the photosensitive sheet member 1a and the image receiving sheet member 3a are developed in a state where they are in close contact with each other.
This adhesive tape 38a is used to prevent the images formed on the image-receiving sheet member 3a from being misaligned and to prevent the images from moving. The adhesive tape roll 38 is formed by pulling out the tip end of the adhesive tape roll 38 and cutting it to a predetermined length.In other words, the adhesive tape roll 38 is formed by a pair of knurling rollers 43 and 44 having irregularities extending in the axial direction formed on the outer periphery. The non-adhesive surface of the tip is sucked and held by the lower surface of the push plate 45, and as it descends with the push plate 45, it is cut by the cutter 46.It is cut to a predetermined length. The adhesive tape 38a has an adhesive surface formed on one side by the push plate 45 that connects the photosensitive member l and the image receiving member 3.
Since it is pressed against these, it is bonded on top of these.

After bonding the adhesive tape 38a, the push plate 45 releases the suction and holding of the non-adhesive surface of the adhesive tape 38a, so that only the push plate 45 rises. In this embodiment, the tip of the adhesive tape roll 38 is pulled out in the direction in which the photosensitive member 1 is transported, but by changing the arrangement of the adhesive tape roll 38, it can also be pulled out in a direction perpendicular to the direction in which the photosensitive member 1 is transported. can. In addition to using the adhesive tape 38a, it is also possible to form an adhesive layer in advance on the drawn-out part 28a of the image-receiving member 3 and press a heat sealer to join the tip of the photosensitive member 1 to the drawn-out part 28a.

A lower end of a slide lever 47 is fixed to the push plate 45, and the slide lever 47 moves up and down while being guided by a guide member (not shown).

In order to move the slide lever 47 up and down, its upper end is connected to one end of a drive lever 49 by a pin 48. This driving reno X-49 is rotatably supported by a shaft 50, and a roller 51 is attached to the tip thereof. This roller 51 is in contact with the outer periphery of a cam 53 driven by a motor 52.

As shown in detail in FIG. 3, the push plate 45 has a box shape, and has a plurality of suction holes 45 in its bottom surface. a is formed. In order to create a negative pressure inside the push plate 45, it is connected to a vacuum source 56 via a flexible pipe 55. In front of this pushing plate 45, a pair of developing rollers 6
0 and 61 are arranged, and the photosensitive sheet member 1 is inserted into the photosensitive sheet member 1.
a and the image receiving sheet member 3a pass through in close contact with each other, and at this time, the developer pod 29 is torn apart. Conveyance rollers 62a, 62b and conveyance rollers 63a, 63b (not shown) are disposed in front of these developing rollers 60, 61, and conveyance rollers 63a, 63b (not shown) are arranged in front of these developing rollers 60, 61 to prevent uneven development. , and transport the spacer 30 portion between them. The conveyance rollers 62a and 62b are fixed to a rotating shaft 64, and the conveying rollers 63a and 63b are fixed to a rotating shaft 65. At one end of these rotating shafts 64, 65,
Gears 66 and 67 are fixed to each other, and by meshing with each other, the conveying rollers 62a and 62b.

63a and 63b rotate at the same peripheral speed.

When the developer pod 29 is torn apart by the pair of developing rollers 60 and 61, a considerable pulling force is required.
If you do it alone, slips are likely to occur. Therefore, in order to increase the pulling force at the initial stage of drawing out the image receiving sheet member 3a, a pair of drawing rollers 70 and 71 are arranged to grip the leading end of the image receiving sheet member 3a and pull it out. If these pull-out rollers 70 and 71 are always close to each other, they will pinch the image-receiving sheet 27 when it arrives, causing uneven development, so one of the pull-out rollers 70 should be retracted before the image-receiving sheet 27 arrives. It is necessary to do so.

Therefore, when the bent piece 72a of the arm 72 holding the pull-out roller 70 at its tip is pushed by the cam 73, the arm 72 swings about the shaft 75 against the spring 74.

The conveyance rollers 62a, 62b, 63a, 63b, the pull-out roller 71. The cam 73 is driven by a motor 78 via a drive system 77. Further, the motor 24, 35, 52.78° air cylinder 14. The shutter 16 is sequence-controlled by a microcomputer so that it operates at a predetermined timing when a start key is operated.

Next, the operation of the above embodiment will be explained. First, the photosensitive member 1 in the form of a roll is loaded onto the core receiver 1) and set at a position where its leading end is pressed against the photosensitive member feeding rollers 22 and 23. In addition, the roll-shaped image receiving member 3 is wound around the core receiver 2.
6, and its tip is connected to the image receiving member feeding rollers 36, 37.
Set it in the nipped position.

(2) When a start key is pressed after placing a subject in front of the shadow lens 17, the shutter 16 is activated and a latent image of the subject is recorded on a part of the photosensitive member 1 positioned at the exposure position P. After this photographing, the motor 35 is started, so the image receiving member 3 nipped by the image receiving member feeding rollers 36 and 37 moves along the support plate 80, 81, and its tip reaches the image receiving member tip position P2. A fixed amount is sent up to. When this constant feeding is detected by the photo sensor, the motor 35 is stopped. When the image receiving member 3 is sent out, the motor 78 also rotates, so that the tip of the image receiving member 3 is exposed to the developing rollers 60, 61 . FM feed rollers 62a, 62b
, 63a, 63b are nipped by the pull-out rollers 70, 71, and in this state, the motor 78 stops.

After the image receiving member 3 is fed in a fixed amount, the motor 24 is started, and the photosensitive member feeding rollers 22 and 23 rotate to perform fixed amount feeding. The tip of the photosensitive member 3 is laterally turned by a curved guide plate 83, and then
It moves along the top of the image receiving member 3. Then, photosensitive member 1
When a sensor such as a photo sensor detects that the tip of the photosensitive member has reached the tip position P1 of the photosensitive member, the rotation of the motor 24 is stopped.

After the photosensitive member 1 has been metered and properly overlaid on the image receiving member 3, the knurling rollers 43, 44 are rotated to meter the leading end of the adhesive tape roll 38. The non-adhesive surface of the leading end of the adhesive tape roll 38 that has been fed in a fixed amount is sucked and held by the lower surface of the push plate 45 . Next, the motor 52 is started to rotate the cam 53 once. As the cam 53 rotates, the push plate 45 descends while sucking and holding the tip of the adhesive tape roll 38 on its lower surface, and the cutter 46 cuts the adhesive tape 38a into a predetermined length. The obtained adhesive tape 38a is pressed against the tip of the photosensitive member 1 and a part of the image receiving member 3 by the pressing plate 45 and adhered thereto.

After the adhesive tape 38a is attached, the pulp provided in the vacuum source 56 is switched and the inside of the push plate 45 is communicated with the atmosphere, so that the suction and holding of the adhesive tape 38a is released.
Thereafter, the push plate 45 rises and returns to the initial position. By joining the adhesive tape 38a, the photosensitive member 1 is joined to the image receiving member 3 with its tip covering the developer pod 29.

Next, the cutter 39 is operated to cut the photosensitive member 1 and the image receiving member 3, and cut the photosensitive sheet member 1a and the image receiving sheet member 3.
Separate into a. After this cutting, the motor 78 is started again, so that the leading end of the image receiving sheet member 3a is caught by the drawing rollers 70, 71 and drawn out. Along with this,
Photosensitive sheet member 1a and image receiving sheet member 3 stacked vertically
A is pulled out with its both sides bitten by conveyance rollers 62a, 62b, 63a, and 63b. When the photosensitive sheet member 1a and the image receiving sheet member 3a are pulled out in an overlapping state, the developer pod 29 is moved by a pair of developing rollers 60.
, 61, the developer pod 29 is torn open and the developer contained therein flows out between the photosensitive sheet member 1a and the image receiving sheet member 3a. This flowed out liquid is spread out by a pair of spreading rollers 60 and 61 so that it has a uniform thickness. Note that the excess developer is stored between the rear end of the photosensitive sheet la and the skirt portion 28b.

After the developer pod 29 is torn open, the arm 72 is rotated clockwise by the cam 73 about the shaft 75, so that the pull-out roller 70 attached to the tip of the arm 72 separates from the photosensitive sheet member 1a, and the photosensitive sheet It waits at the retracted position until the drawing of the member 1a and the image receiving sheet member 3a is completed. However, the conveyance rollers 62a, 62b, 63a, 6
Since the photosensitive sheet member 3b continues to rotate, the photosensitive sheet member 1a and the image receiving sheet member 3a are discharged onto the tray 86 as an instant photographic unit 85 while being in close contact with each other.

The instant photo unit 85 discharged onto the tray 86 is left as it is for approximately 60 seconds, during which transfer and fixing processing is performed. Thereafter, by peeling off only the image-receiving sheet 27, an instant photograph with an image of the subject recorded thereon can be obtained.

After the cutter 39 is operated, the motor 24 is reversed, and the air cylinder 14 is operated to advance the return roller 13. As a result, the cutter 39 position I
The leading end of the photosensitive member 1 that has been sent out is returned to the position of the photosensitive member feeding rollers 22, 23, thereby saving the amount of expensive photosensitive member 1 used.

Furthermore, when photographing, by operating the start key again, the photosensitive sheet member 1 is
a and the image receiving sheet member 3a are brought into close contact with each other and are discharged onto the tray 86 as an instant photographic unit.

The instant photo unit 85 is used for a certain period of time (6
If you peel it off after heating (25-30°C), the finish will be uniform. For this purpose, the camera housing 10
It is preferable to heat the container for a certain period of time and then discharge it to the tray 86. Further, the photosensitive member and the image receiving member are subjected to light shielding treatment to prevent fogging even if they are left in a bright room after development. If this light shielding treatment is omitted, the cost of the photosensitive member and the image receiving member can be reduced, but in this case, it is necessary to carry out the development and fixing treatment in a dark room.

In order to meet these demands, it is preferable to provide a device that can shield the inside of the camera housing 10 from light and temporarily store the instant photographic unit 85 inside the camera housing 10.

FIG. 5 shows an embodiment in which a windmill-like rotating body that rotates intermittently is provided. An obliquely inclined chute 90 is arranged in front of the pull-out rollers 70, 71, and a stopper 91 is provided at the tip thereof. This stopper 91 is attached to a solenoid 92 and is retracted when the solenoid 92 is energized, causing the chute 9
The instant photographic unit 85 which is stopped above 0 can be made to flow down. The solenoid 92 is energized by a timer 93 for a sufficient period of time to cause the instant photographic unit 85 to flow down the chute 90.

The rotating body 95 has a pair of discs 96 fixed to a rotating shaft 97 with an appropriate distance therebetween, and is partitioned into 8 ([!I) compartments 99 by a plurality of partition plates 98.

The rotating body 95 is intermittently rotated, for example, by 45 degrees every 15 seconds by an intermittent feed mechanism 101 operated by a motor 100. This intermittent movement of the intermittent feed mechanism 101 is detected by the switch 102, which activates the timer 93 in synchronization with the rotating body 95.
While the solenoid 92 is stopped, the solenoid 92 is energized for a predetermined period of time. Note that if a pulse motor is used as the motor 100, the intermittent feed mechanism 101 can be omitted.

The instant photographic unit 85 ejected from the rotating body 95 passes through an outlet 10a formed in the camera housing 10.
and is stored in the tray 105. When using an instant photo unit that has not been subjected to light-shielding treatment, it is necessary to prevent light from entering the camera housing 10 from the exit 10a. It is preferable to arrange it at the outlet 10a.

A heater 106 having an automatic temperature adjustment mechanism is disposed below the rotating body 95 to maintain the temperature inside the rotating body 9-5 at, for example, 25°C.

In this embodiment, the rotating body 95 rotates intermittently every 15 seconds, and when the rotating body 95 is stopped, the stopper 9
1 evacuates. When the stopper 91 is retracted, the unfolded instant photo unit 85 that has been stopped on the chute 90 flows down and enters the compartment 99 of the rotating body facing the chute 90. The instant photo unit 85 housed in the compartment 99 of the rotating body 95 is heated to 25° C. by the heater 106 . Rotating body 9
5 rotates 180 degrees after about 60 seconds, so the instant photo unit 85 stored in the compartment 99
is discharged into the tray 105.

As a result, the instant photo unit 85
Since the image is left at 725° C. for 60 seconds, transfer and fixing proceed smoothly, resulting in a uniform image finish.

Further, since the image receiving sheet 27 is discharged after the transfer and fixing, it is possible to prevent the image receiving sheet 27 from being peeled off when the transfer and fixing are insufficient.

〔Effect of the invention〕

The present invention having the above configuration uses a roll-shaped photosensitive member and a roll-shaped image receiving member, and is cut into sheets after shooting, so when shooting in large quantities, punctures occur frequently unlike conventional packed film units. There is no need to replace the camera, making photography extremely convenient. Furthermore, since the present invention is capable of mass continuous photographing, it is convenient in cases where it is difficult to provide an operator due to cost considerations, such as coin-in type automatic photographing machines. Furthermore, since there is no need for punctures, the cost is reduced accordingly, and since there is no need for a structure for pulling out each frame one by one from the pack, it is possible to significantly reduce the shooting cost per frame.
