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 phenomenon liquid pod is cleaved and the developer contained in the phenomenon pod is pushed out to be 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 commercial use with a large number of images taken, for example, a coin-operated ID photo shooter, studio shooter, license shooter, CR
In the image capturing apparatus of T, etc., there is a problem that photographing is troublesome because the packs have to be exchanged frequently. On the other hand, there has been proposed a magazine which accommodates a large number of packs and automatically exchanges the packs (for example, JP-A-47-4561).
No. 8), in this case, there is a problem that a plurality of incidental equipment such as a device for taking out the film unit from the pack and a pack changing device are required. Also, in order to ensure that the film units can be pulled out one by one from the pack, the structure has a pull-out sheet with a tab joined to the front edge of the photosensitive sheet. There was a difficulty that it was 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.

Be prepared.

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. A cutter 25 is disposed below the photosensitive member feeding rollers 22 and 23, and the photosensitive member 1 is fed by one frame and then operated to cut into the photosensitive sheet member 11a.

A large number of sheet-shaped image receiving sheet members 3 are placed on the lift 27. As shown in detail in FIG. 3, the image receiving sheet member 3 includes an image receiving sheet 4 for receiving the latent image recorded on the photosensitive member 1 to form an image, and a pull-out portion 5 joined to the leading end portion thereof. The developing solution pod 6 attached to the drawer portion 5 and the skirt portion 7 joined to the rear end portion of the image receiving sheet 4 for receiving the excess developing solution. The developer pod 6 has a portion 6a containing no developer in the center thereof. Spacers 8 are bonded to both sides of the image receiving sheet 4, and by keeping a constant distance from the photosensitive sheet member 1, the developing solution pushed out from the developing solution pod 6 is spread to a certain thickness.

A suction drum 28 having a large number of suction holes on its outer peripheral surface is rotatably arranged above the lift table 27. The suction drum 28 sucks and holds the skirt portion 7 and rotates to separate and take out the image receiving sheet members 3 one by one, and the pair of image receiving sheet member feeding rollers 29 and 30 bite the image receiving sheet members. The suction drum 28 completes the feeding of the skirt portion 7 by one rotation and then stops. The suction drum 28 and the image receiving sheet member feed rollers 29, 30 are driven by the motor 24 via a transmission mechanism and a clutch mechanism.

The elevating table 27 is biased upward by, for example, a spring 32, and stops at a position where the image receiving sheet member 3 at the uppermost portion abuts on the suction drum 28. In this state, the image receiving sheet member 3 on the uppermost part of the lifting table 27.
, The leading end of the drawer portion 5 is seen from the upper end of the regulation plate 33. In addition, in the lift table 27, the image receiving sheet member 3 is moved by a link mechanism driven by a pulse motor.
It is also possible to raise by a predetermined step each time a sheet is discharged. Further, the suction plate is attached to the movable arm, the movable arm is lowered to suck the suction plate onto the image receiving sheet member 3, and then the movable arm is raised and moved in the horizontal direction to move the image receiving sheet member 3 to the image receiving sheet feeding roller. It is also possible to let 29, 30 bite.

The image receiving sheet member 3 is fed to the image receiving sheet member leading end position P2 by the image receiving sheet member feeding rollers 29 and 30. The image receiving rollers 29 and 30 are composed of three rollers having a narrow width so as not to tear the developer pod 6 when the image receiving sheet member 3 is pulled out. Avoid the part that is housed. Since the image receiving sheet member leading end position P2 is located ahead of the photosensitive member leading end position P1, the image receiving sheet member feed rollers 29 and 30 are connected to the photosensitive member feed rollers 22 and 2.
The feed amount is set to be larger than 3.

When the photosensitive member 1 is conveyed while being superimposed on the image receiving sheet member 3, the adhesive tape 38a is attached to the front end portion of the photosensitive member 1 and the image receiving sheet member 3. The adhesive tape 38a is misaligned when the photosensitive sheet member 1a and the image receiving sheet member 3 are developed in a state where they are in close contact with each other, so that the image formed on the image receiving sheet member 3 is misaligned or image-shifted. It is used to prevent the flow of. The adhesive tape 38a is obtained 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 circumference, and the non-adhesive surface at the tip end thereof is sucked and held by the lower surface of the pressing plate 45. When being lowered together with the push plate 45, it is cut by the cutter 46. The adhesive tape 38a cut into a predetermined length is bonded on the photosensitive member 1 and the image receiving sheet member 3 because the adhesive surface formed on one surface by the pressing plate 45 is pressed against the photosensitive member 1 and the image receiving sheet member 3. 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, so that only the pressing plate 45 moves up.

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.

Although the photosensitive member 1 is joined to the image receiving sheet member 3 by using an adhesive tape in the above-mentioned embodiment, instead of this, the drawing portion 5 is used.
It is also possible to previously form an adhesive layer on the photosensitive member 1 and the image receiving sheet member 3 by using a heat sealer.

As shown in detail in FIG. 2, the push 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 3 pass in a state of being in close contact with each other, and at this time, the developer pod 6 is cleaved. Conveying rollers 62a and 62b and conveying rollers 63a and 63b (not shown) are arranged in front of the developing rollers 60 and 61 to face the developing rollers 60a and 61b in order to prevent uneven development. , The spacer 8 is sandwiched and conveyed. 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, the gear 6
6, 67 are fixed to each other, and by meshing these, the conveying rollers 62a, 62b, 63a, 63
b and rotate at the same peripheral speed.

When the developer pod 6 is cleaved by the pair of developing rollers 60 and 61, a considerable pulling force is required,
Slip is likely to occur only with the narrow conveying rollers 62a, 62b, 63a, 63b. Therefore, in the initial stage of pulling out the image receiving sheet member 3, a pair of pulling rollers 70 and 71 are arranged in order to increase the pulling force, and the tip of the image receiving sheet member 3 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 to cause unevenness in development. It is necessary to evacuate. For this purpose, the arm 7 holding the pull-out roller 70 at its tip is used.
2 is, when the bent piece 72a is pushed by the cam 73,
It swings around the shaft 75 as a fulcrum against the spring 74.

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. Further, the motors 24, 52, 78, the air cylinder 14, the shutter 16
When the start key is operated, the sequence control is performed by the microcomputer so that the microcomputer operates at a predetermined timing.

Next, the operation of the above embodiment will be described. First, the photosensitive member 1 is loaded, and the leading end of the photosensitive member is fed to the photosensitive member feeding rollers 22 and 2.
Set it to the position where it was nipped by 3. Further, a large number of image receiving sheet members 3 are placed on the lift table 27. When the subject is placed in front of the taking lens 17 and the start key is pressed, the shutter 16 is actuated to record an image of the subject on a part of the photosensitive member 1 positioned at the exposure position P. Since the motor 24 is started after this photographing, the suction drum 28 makes one rotation through the one-rotation clutch mechanism. At the same time, since only the portion of the suction drum 28 which is in contact with the skirt portion 7 is made negative pressure, the suction drum 28 sucks and holds the negative pressure, and the tip of the image receiving sheet member 3 is bitten by the image receiving sheet member feeding rollers 29 and 30. Let it go. The image receiving sheet member feed rollers 29 and 30 are driven by the motor 24 via a clutch mechanism, and feed the image receiving sheet member 3 along the support plate 80. Since the motor 64 also rotates when the image receiving sheet member 3 is sent out, the front ends of the image receiving sheet member 3 are the developing rollers 47, 48, the conveying rollers 49a, 49b, 50a, 50b, and the pull-out roller 5.
It is in a state of being nipped by 6, 57. When the photo sensor detects that the tip of the image receiving sheet member 3 has reached the image receiving sheet member leading end position P2, the rotation of the image receiving sheet member feed rollers 29 and 30 is stopped, and the motor 78 is used.
Also stops rotating.

After the image receiving sheet member 3 is fed in a fixed amount, the photosensitive sheet member feeding rollers 22 and 2 are driven by the motor 24 through the clutch mechanism.
3 rotates to feed the photosensitive member 1 in a fixed amount. When the photosensitive member 1 is moved in the lateral direction by the guide member 81 and is conveyed while overlapping the image receiving sheet member 3, it is detected that the leading end of the photosensitive member 1 reaches the leading end position P1 of the photosensitive member. The rotation of the motor 24 is stopped. After the photosensitive member 1 is fed in a fixed amount and properly overlaps the image receiving sheet member 3, the cutter 25 is operated to separate the photosensitive sheet member 1a.

After the operation of the cutter 25, the knurl roller 43,
44 rotates to feed the tip of the adhesive tape roll 38 in a fixed amount. The adhesive tape roll 38 fed by the fixed amount is
The non-adhesive surface of the tip 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 the adhesive tape 3 having a predetermined length is cut by the cutter 46.
Cut to 8a. The obtained adhesive tape 38a is pressed by the pressing plate 45 to the front end portion of the photosensitive sheet member 1a and a part of the image receiving sheet member 3 and adhered thereto. After the adhesive tape 38a is adhered, the valve provided in the vacuum source 56 is switched and the inside of the pressing plate 45 is communicated with the atmosphere, so that the suction and holding of the adhesive tape 38a is released, and then the pressing plate 45 rises. And return to the initial position. By the joining of the adhesive tape 38a, the photosensitive sheet member 1a is joined to the image receiving sheet member 3 in a state where the leading end of the photosensitive sheet member 1a covers the developer pod 6.

Next, since the motor 78 is started again, the leading edge of the image receiving sheet member 3 is bitten by the pull-out rollers 70 and 71 and pulled out. Along with this, the photosensitive sheet member 1a and the image receiving sheet member 3 which are vertically overlapped with each other are conveyed by the conveying rollers 62a and 62a.
Both sides are bited by b, 63a, 63b and pulled out. When the photosensitive sheet member 1a and the image receiving sheet member 3 are pulled out in a state of being overlapped with each other, the developer pod 6 passes through the pair of developing rollers 60 and 61, so that the developer pod 6 is cleaved and the inside thereof is pulled out. The contained developing solution flows out between the photosensitive sheet member 1 a and the image receiving sheet member 3.
The developing solution that has flowed out is spread by the pair of spreading rollers 60 and 61 so that the thickness becomes uniform. The excess developer is stored between the rear end of the photosensitive sheet 1a and the skirt 7.

After the developing solution pod 6 is torn, the arm 72 is rotated clockwise by the cam 73 about the shaft 75 as a fulcrum.
The pull-out roller 70 attached to the tip of the arm 72 separates from the photosensitive sheet member 1a, and stands by at the retracted position until the pull-out of the photosensitive sheet member 1a and the image receiving sheet member 3 is completed. However, the transport rollers 62a, 62b, 63a, 63
Since the sheet b is continuously rotated, the photosensitive sheet member 1a and the image receiving sheet member 3 are ejected onto the tray 86 as the instant photographic unit 85 with the image sheet sheet member 3 in close contact with each other.

The instant vacuum unit 85 discharged to 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 4 is peeled off, an instant photograph in which the image of the subject is recorded can be obtained.

After the operation of the cutter 25, 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 25 is returned to the positions of the photosensitive member feed rollers 22 and 23, and the amount of costly use of the photosensitive member 1 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 3 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 photosensitive member 1 and the image receiving sheet member 3 are light-shielded in order to prevent fog even if left in a bright room after being developed. If you omit this shading process,
The costs of the photosensitive member 1 and the image receiving sheet member 3 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 photographic unit 85 therein.

FIG. 4 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 feed 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 5 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. In addition, the instant photo unit 85
Since the sheet is discharged after transfer / fixing, the image receiving sheet 27 will not be peeled off in a state where transfer / fixing is insufficient.

〔The invention's effect〕

The present invention having the above-mentioned configuration uses a roll-shaped photosensitive member and a sheet-shaped image receiving sheet member, and the photosensitive member is cut into sheets after photographing, so that when a large number of photographing is performed, a conventional packed film is used. Since it is not necessary to change the pack as frequently as the unit, the photographing is extremely simple. Further, the present invention is suitable for a large number of continuous shootings, so that it is preferable in the case where 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 member is positioned on the exposed photosensitive member so that the exposed photosensitive member cut into one frame covers the image receiving sheet of the image receiving sheet member and the developer pod, the photosensitive member and the image receiving sheet member are separated from each other. The structure of these feeding means is simplified without the need for complicated movement.
