Description

TECHNICAL FIELD The present invention relates to a peel apart type instant photographing apparatus for separating an image receiving sheet and a photosensitive sheet after development processing.

[Prior art]

A camera using a peel apart type instant film unit (hereinafter, simply referred to as a film unit) has been widely known. This film unit is composed of a photosensitive sheet for recording a latent image and an image receiving sheet for receiving the latent image. A state in which a plurality of film units are overlapped so that they are located on both sides of a support plate. It is stored in a pack. After loading this pack in the camera and taking a picture, if you pull out the tab joined to the photosensitive sheet side, the photosensitive sheet will be pulled out while wrapping around the back of the support plate, and its leading end will become the leading end of the image receiving sheet. It sticks out from the camera's film outlet. In this state, the tabs will peel off, so if you pull out the edges of the photosensitive sheet and the image receiving sheet that are in close contact with each other by hand, the photosensitive sheet and the image receiving sheet will gradually come into close contact with each other from the front edge, and between the pair of developing rollers. pass. When passing through the developing roller, the developing solution pod is cleaved and the developing solution contained therein is pushed out and developed between the photosensitive sheet and the image receiving sheet. By this developing solution, the latent image recorded on the photosensitive sheet is transferred to the image receiving sheet, and an image is formed on the image receiving sheet.

In the conventional peel-apart type instant photo described above, since there are about 10 film units stored in one pack, there is not much problem when used in an amateur camera with a small number of shots,
For business use with a large number of images taken, for example, a coin-operated ID photo shooting device, a studio shooting device, a license shooting device, C
In the RT image capturing device and the like, there is a problem in that capturing is troublesome because the packs have to be replaced frequently. On the other hand, it has been proposed to provide a magazine accommodating a large number of packs so that the packs can be automatically replaced (for example, JP-A-47-456).
No. 18), in this case, there is a problem that complicated auxiliary equipment such as a device for taking out the film unit from the pack and a pack changing device is required. In addition, in order to ensure that the film units can be pulled out one by one from the pack, a pull-out sheet with a tab is joined to the front end of the photosensitive sheet, and a transport sheet is joined to the front end of the image receiving sheet. However, due to this complicated structure, the cost of the film unit is high. On the other hand, there has been proposed a photosensitive sheet and an image receiving sheet which are supplied in a roll form so that a film pack is not used (for example, Japanese Patent Publication No. 39-39).
22072), there is a problem in that the feeding of the photosensitive sheet and the image receiving sheet becomes complicated simply by making them roll-shaped.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

〔Example〕

In FIG. 1, a photosensitive member 1 for recording a latent image is wound around a winding core 2, and is removably loaded in a winding core receiver 11 arranged above the camera housing 10. The photosensitive member 1 includes a guide roller 12, a returning roller 13,
The exposure position P is reached through the guide rollers 14 in sequence. The returning roller 13 is a rod 15 of the air cylinder 15.
It is connected to a and cuts into sheets and then moves forward to slightly return the tip of the photosensitive member 1, thereby eliminating waste of the photosensitive member 1. A photographing lens 17 having a lens shutter 16 is arranged in front of the exposure position P, and an image of a subject is formed on the photosensitive member 1 in the opening of the lens shutter 16 and recorded as a latent image on the photosensitive member 1. To do. In order to prevent external light from entering the photosensitive member 1 at the exposure position P, the exposure frame 18 and the taking lens 17 are provided with a bellows 19. A plate 20 is provided to ensure the flatness of the photosensitive member 1 at the exposure position P. A pair of photosensitive member feed rollers 22 and 23 are disposed at the lower end of the exposure frame 18, and are driven by a motor 24 to perform constant feed until the exposed front end of the photosensitive member 1 reaches the photosensitive member front end position P1. To do.

An image receiving member 3 is wound around a core 4 for receiving the latent image recorded on the photosensitive member 1 to form an image, and is detachably mounted on a core receiver 26 arranged below the camera housing 10. Has been done. As shown in FIG. 2, in the image receiving member 3, image receiving sheets 27 and intermediate sheets 28 are alternately joined. A developer pod 29 containing a developer is attached to the intermediate sheet 28 by heat sealing or the like. The developing solution pod 29 has a portion 29a in which the developing solution is not housed, formed in the center thereof. Spacers 30 are joined to both sides of the image receiving sheet 27, and by keeping a constant distance from the photosensitive member 1,
The developer extruded from the developer pod 29 is spread to have a constant thickness. An alternate long and short dash line 31 indicates a cutting line when the sheet is cut into sheets, and the intermediate sheet 2 is cut by this cutting.
8 is separated into a drawer portion 28a and a skirt portion 28b for receiving the excess developer.

The image receiving member 3 is fed to the image receiving member front end position P2 by a pair of image receiving member feeding rollers 36 and 37 driven by a motor 35. The image receiving rollers 36 and 37 are
In order to prevent the developer pod 29 from being cleaved when the image receiving member 3 is pulled out, as shown in FIG.
It is composed of individual rollers and avoids the portion of the developer pod 29 in which the developer is stored. Since the image receiving member front end position P2 is ahead of the photosensitive member front end position P1, the image receiving member feed rollers 36 and 37 are set to have a larger feed amount than the photosensitive member feed rollers 22 and 23.
Then, after the photosensitive member 1 is overlaid on the image receiving member 3 and the adhesive tape 38a is adhered thereon, as shown in FIG. 4, the photosensitive sheet member 1a and the image receiving sheet member 3a are attached.
Then, it is cut by the cutter 39. Instead of the cutter 39, cutters 40 and 41 are arranged near the photosensitive member sending rollers 22 and 23 and near the image receiving member sending rollers 36 and 37, respectively, to cut the photosensitive member 1 and the image receiving member 3 separately. You may.

When the adhesive tape 38a is developed with the photosensitive sheet member 1a and the image receiving sheet member 3a in close contact with each other,
The two are used to prevent misalignment of the two and the resulting misalignment of the image formed on the image receiving sheet member 3a and the flow of the image. This adhesive tape 3
8a is formed by pulling out the tip of the adhesive tape roll 38 and cutting it into a predetermined length. That is,
The adhesive tape roll 38 is pulled out for a certain length by a pair of knurled rollers 43, 44 having an unevenness extending in the axial direction formed on the outer periphery, and the non-adhesive surface at the tip thereof is sucked by the lower surface of the pressing plate 45. When held and lowered together with the push plate 45, it is cut by the cutter 46. The adhesive tape 38a cut into a predetermined length has an adhesive surface formed on one side by the pressing plate 45 on the photosensitive member 1 and the image receiving member 3.
It is pressed against and is bonded onto them. After the adhesive tape 38a is joined, the pressing plate 45 releases the suction / holding of the non-adhesive surface of the adhesive tape 38a.
Only the push plate 45 rises. In this embodiment, the tip of the adhesive tape roll 38 is pulled out in the transport direction of the photosensitive member 1, but this can also be pulled out in the direction orthogonal to the transport direction of the photosensitive member 1 by changing the arrangement of the adhesive tape roll 38. it can. Instead of using the adhesive tape 38a, it is also possible to previously form an adhesive layer on the pull-out portion 28a of the image receiving member 3 and press the heat sealer to bond the tip of the photosensitive member 1 to the pull-out portion 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. The drive lever 49 is rotatably supported by a shaft 50, and a roller 51 is attached to the tip thereof. This roller 5
1 is in contact with the outer periphery of the cam 53 driven by the motor 52.

As shown in detail in FIG. 3, the pushing plate 45 has a box shape, and a plurality of suction holes 45a are formed on the bottom surface thereof. In order to make the inside of the push plate 45 negative, it is connected to a vacuum source 56 via a flexible pipe 55. In front of the push plate 45, a pair of deploying rollers 6
0 and 61 are arranged in the photosensitive sheet member 1
a and the image receiving sheet member 3a pass in a close contact state, at which time the developer pod 29 is cleaved. Transport rollers 62a and 62b are provided in front of the developing rollers 60 and 61.
And conveyance rollers 63a and 63b (not shown) are arranged opposite to the conveyance rollers 63a and 63b, and in order to prevent uneven development, the spacers 30 are conveyed with the spacer 30 interposed therebetween. The conveying rollers 62a and 62b are fixed to the rotating shaft 64, and the conveying rollers 63a and 63b are fixed to the rotating shaft 65. At one end of these rotary shafts 64, 65,
Gears 66 and 67 are fixed to each other, and by meshing with each other, the conveying rollers 62a, 62b, 63
a and 63b rotate at the same peripheral speed.

When the developer pod 29 is cleaved by the pair of developing rollers 60 and 61, a considerable pulling force is required, so that the narrow conveying rollers 62a, 62b, 63a and 63.
Slip is likely to occur only with b. Therefore, in the initial stage of pulling out the image receiving sheet member 3a, a pair of pulling rollers 70 and 71 are arranged to increase the pulling force, and the tip of the image receiving sheet member 3a is bitten and pulled out.
If the pull-out rollers 70 and 71 are always close to each other, when the image-receiving sheet 27 arrives, the pull-out rollers 70 and 71 pinch the image-receiving sheet 27 and uneven development occurs. Therefore, one of the pull-out rollers 70 is retracted before the image-receiving sheet 27 arrives. Will be required. For this reason, the arm 72 holding the pull-out roller 70 at the tip swings against the spring 74 when the bent piece 72a is pushed by the cam 73, with the shaft 75 as the fulcrum.

The transport rollers 62a, 62b, 63a, 63b, the pull-out roller 71, and the cam 73 are driven by a motor 78 via a drive system 77. The motors 24, 35, 52, 78, the air cylinder 14, and the shutter 16 are sequence-controlled by a microcomputer so as to operate at a predetermined timing when the start key is operated.

Next, the operation of the above embodiment will be described. First, the roll-shaped photosensitive member 1 is loaded in the core receiver 11, and the leading end of the photosensitive member 1 is set at a position where it is nipped by the photosensitive member feed rollers 22 and 23. Further, the roll-shaped image receiving member 3 is attached to the winding core receiver 2
6 and the front ends of the image receiving member feed rollers 36 and 37.
Set to the position where it is nipped.

When the subject is placed in front of the taking lens 17 and the start key is pressed, the shutter 16 operates and a latent image of the subject is recorded on a part of the photosensitive member 1 positioned at the exposure position P. Since the motor 35 is started after this photographing, the image receiving member 3 nipped by the image receiving member feeding rollers 36 and 37 moves along the upper portions of the support plates 80 and 81, and the tip thereof reaches the image receiving member tip position P2. Is sent to a fixed amount. Then, when this fixed amount feeding is detected by the photo sensor, the motor 35 stops. Since the motor 78 also rotates when the image receiving member 3 is sent out, the tip end of the image receiving member 3 is spread rollers 60, 61, conveying rollers 62a, 62b ,.
63a, 63b and the pull-out rollers 70, 71 are nipped, and in this state, the motor 78 is stopped.

Since the motor 24 is started after the fixed amount feeding of the image receiving member 3, the photosensitive member feeding rollers 22 and 23 rotate to perform the fixed amount feeding. The tip of the photosensitive member 3 is laterally changed by the curved guide plate 83,
It moves along the top of the image receiving member 3. Then, the photosensitive member 1
When it is detected by a sensor, for example, a photo sensor that the tip of the motor reaches the photosensitive member tip position P1, the rotation of the motor 24 is stopped.

After the photosensitive member 1 is fed by a fixed amount and properly overlaps the image receiving member 3, the knurl rollers 43, 44 rotate to feed the front end portion of the adhesive tape roll 38 by a fixed amount. The non-adhesive surface of the tip end of the adhesive tape roll 38 fed by the fixed amount is sucked and held by the lower surface of the pressing plate 45. Next, the motor 52 is started and the cam 53 is rotated once. Due to the rotation of the cam 53, the pressing plate 45 descends while the tip of the adhesive tape roll 38 is sucked and held on the lower surface thereof, and is cut into a predetermined length of adhesive tape 38a by the cutter 46. The obtained adhesive tape 38a is pressed against the tip portion 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 adhered, the valve provided in the vacuum source 56 is switched, and the pressing plate 45 is switched.
Since the inside of the adhesive tape is communicated with the atmosphere, the suction / holding of the adhesive tape 38a is released, and then the push plate 45 moves up and returns to the initial position. By the bonding of the adhesive tape 38a, the photosensitive member 1 is bonded to the image receiving member 3 with its tip end covering the developer pod 29.

Next, the cutter 39 operates to cut the photosensitive member 1 and the image receiving member 3, and the photosensitive sheet member 1 a and the image receiving sheet member 3 are cut.
Separated into a and. After this cutting, the motor 78 is started again, so that the leading end of the image receiving sheet member 3a is bitten by the pull-out rollers 70 and 71 and pulled out. With this,
The photosensitive sheet member 1a and the image receiving sheet member 3 which are vertically stacked.
Both sides of a are pulled out by the conveyance rollers 62a, 62b, 63a, 63b. When the photosensitive sheet member 1a and the image receiving sheet member 3a are pulled out in a state of being overlapped with each other, the developer pod 29 has a pair of developing rollers 6
The developer pod 29 is cleaved in order to pass through 0 and 61, and the developer contained in the developer pod 29 is released into the photosensitive sheet member 1a.
And the image receiving sheet member 3a. The developing solution that has flowed out is spread by the pair of spreading rollers 60 and 61 so that the thickness becomes uniform. Excess developer is stored between the rear end of the photosensitive sheet 1a and the skirt 28b.

After the developer pod 29 is cleaved, the arm 72 is rotated clockwise by the cam 73 about the shaft 75 as a fulcrum, so that the pull-out roller 70 attached to the tip of the arm 72 is separated from the photosensitive sheet member 1a, and the photosensitive sheet is moved. It waits at the retracted position until the pulling out of the member 1a and the image receiving sheet member 3a is completed. However, the transport rollers 62a, 62b, 63a,
Since 63b continuously rotates, the photosensitive sheet member 1a
And the image receiving sheet member 3a are in close contact with each other and are discharged onto the tray 86 as the instant photographic unit 85.

The instant photographic unit 85 discharged onto the tray 86 is left as it is for about 60 seconds, during which the transfer fixing process is performed. After that, if only the image receiving sheet 27 is peeled off, an instant photograph in which the image of the subject is recorded can be obtained.

After the operation of the cutter 39, the motor 24 is rotated in the reverse direction and the air cylinder 14 is operated to move the returning roller 13 forward. As a result, the tip of the photosensitive member 1 that has been fed to the position of the cutter 39 is returned to the positions of the photosensitive member feed rollers 22 and 23, and the amount of expensive photosensitive member 1 used is saved.

Further, when performing photographing, if the start key is operated again, the photosensitive sheet member 1 after exposure is exposed by the procedure described above.
The sheet a and the image receiving sheet member 3a are in close contact with each other and are discharged onto the tray 86 as an instant photographic unit.

The instant photo unit 85 can be operated for 60
Second) After heating (25 to 30 ° C.) and peeling off, the finish becomes uniform. For this purpose, it is desirable to heat the inside of the camera housing 10 for a certain period of time and then discharge it to the tray 86. Further, the light-sensitive member and the image-receiving member are light-shielded in order to prevent fog even if left in the bright room after being developed. If this light-shielding process is omitted, the cost of the photosensitive member and the image receiving member can be reduced, but in that case, it is necessary to perform the developing and fixing process in a dark room. In order to meet these demands, it is preferable to provide a device that shields the inside of the camera housing 10 and temporarily holds the instant photo unit 85 therein.

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

The rotating body 95 has a pair of discs 96 fixed to the rotating shaft 97 with an appropriate interval, and is partitioned into eight compartments 99 by a plurality of partition plates 98. The rotating body 95 is
By the intermittent feed mechanism 101 operated by the motor 100,
For example, it rotates intermittently by 45 degrees every 15 seconds. The intermittent movement of the intermittent feed mechanism 101 is detected by the switch 102, whereby the timer 93 is activated at the timing synchronized with the rotating body 95, and the solenoid 92 is energized for a predetermined time within the period in which the rotating body 95 is stopped. To be done. In addition,
If a pulse motor is used as the motor 100, the intermittent feeding mechanism 101 can be omitted.

The instant photographic unit 85 discharged from the rotating body 95 has an outlet 10a formed in the camera housing 10.
It is accommodated in the tray 105 through. When using an instant photographic unit that has not been light-shielded, it is necessary to prevent light from entering the camera housing 10 through the outlet 10a. Therefore, a flexible light-shielding sheet is used as a blind. It may be arranged at the outlet 10a. A heater 106 having an automatic temperature adjusting mechanism is arranged below the rotating body 95 so that the temperature inside the rotating body 95 is maintained at 25 ° C., for example.

In this embodiment, the rotating body 95 rotates intermittently every 15 seconds,
When the rotating body 95 is stopped, the stopper 91
Will evacuate. When the stopper 91 is retracted, the developed instant photo unit 85 stopped on the chute 90 flows down and enters the compartment 99 of the rotating body facing the chute 90. The instant photographic unit 85 stored in the compartment 99 of the rotating body 95 is
It is heated to 25 ° C. by the heater 106. Rotating body 95
Will rotate 180 degrees after about 60 seconds,
The instant photo unit 85 stored in the tray 9 is discharged into the tray 105. As a result, the instant photographic unit 85 is left for 60 seconds at 25 ° C., so that transfer / fixing proceeds satisfactorily and the image finish becomes uniform. Further, since the image receiving sheet 27 is discharged after transfer / fixing, it is possible to prevent the image receiving sheet 27 from being peeled off in a state where transfer / fixing is insufficient.

[Advantages of the Invention] The present invention having the above-described configuration uses a roll-shaped photosensitive member and a roll-shaped image receiving member, and cuts into sheets after photographing, so that when a large number of photographing is performed, a conventional packed film unit As described above, it is not necessary to change the pack frequently, and photographing is extremely simple. Further, the present invention is suitable for a large amount of continuous shooting, and is therefore convenient when it is difficult to arrange an operator in terms of cost, such as a coin-insertion type automatic shooting machine. Further, since the pack is not required, the cost is reduced accordingly, and the structure for pulling out one by one from the pack is also unnecessary, so that the photographing cost per frame can be significantly reduced. Further, since the image receiving sheet of the image receiving member is positioned on the exposed photosensitive member sent out from the exposure position, there is no need to move the photosensitive member and the image receiving member intricately, and the configuration of the photosensitive member and the feeding means of the image receiving member is improved. It will be easy.
