Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image receiving member used in beer apartment type instant photography in which an image receiving sheet member and a photosensitive sheet member are separated after development processing.

[Prior art]

BACKGROUND ART Beer apartment type instant film units (hereinafter simply referred to as film units) have been widely known. This film unit is composed of a photosensitive sheet member that records a latent image, and an image receiving sheet member that receives this latent image and forms a developed image. The film units are stacked on top of each other and stored in the flat. After loading this pack into the camera and taking a picture, if you pull out the tab connected to the photosensitive sheet member side, the photosensitive sheet member will be pulled out while going around behind the support plate, and its tip will be attached to the image receiving sheet member. The film protrudes from the camera's film outlet while being in close contact with the tip of the film.

In this state, the tab will be peeled off. Next, if you hold the ends of the photosensitive sheet member and image receiving sheet member that are in close contact with each other and pull them out, the photosensitive sheet member and image receiving sheet member will gradually come into close contact with each other from the leading end, and the pair will unfold. Pass between the rollers. When passing through this developing roller, the developer pod is torn open and the developer contained therein is pushed out and spread between the photosensitive sheet member and the image receiving sheet member. With this developer, the latent image recorded on the photosensitive sheet member is transferred to the image-receiving sheet member, and an image is formed on this image-receiving sheet member.

In the conventional beer-apart type instant photograph mentioned above, the image-receiving sheet member is separated for each frame, and the image-receiving sheet member is combined with the photosensitive sheet member for one frame to form a unit and stored in the pack. This pack can only hold about 10 film units, so it is not a big problem when used with an amateur camera that takes a small number of shots, but for professional use, where a large number of shots are taken, for example, a coin-in type camera. ID photographic device.

BACKGROUND ART In studio photographing devices, driver's license photographing devices, CRT image photographing devices, and the like, there is a problem in that punctures must be replaced frequently, making photographing troublesome. Also, the cost of manufacturing the bank.

Another drawback is that the cost per film is high due to the cost of storing the film unit in the pack, the cost of photographing, etc.

[Problem that the invention seeks to solve]

The present invention provides an instant photographic image receiving system that allows mass photographing to be easily carried out and at the same time reduces the photographing cost per photograph. A plurality of openings are formed at predetermined intervals, an image receiving sheet is bonded behind the openings, and a developer pod containing a developer is attached to the upper surface of the support.

The image receiving member of the present invention is loaded into a photographing device in the form of a roll, and is cut between each image receiving sheet into image receiving sheet members for one frame, and this image receiving sheet member is stacked on a photosensitive sheet member. Unitize. At this time, it is preferable that the photosensitive sheet member is also formed into a roll, cut into one frame after photographing, and then stacked on the image receiving member of the present invention.

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

〔Example〕

As shown in FIG. 1, the image receiving member 1 is composed of an image receiving sheet 2 that receives a latent image from a photosensitive member and forms a developed image on an image receiving surface 2a, and a support 4 to which a developer pod 3 is attached. ing. The support 4 has a thickness corresponding to the thickness of the developer, and has a plurality of openings 5 formed at a predetermined pitch corresponding to the screen size. Furthermore, a layer of adhesive N6 is provided on the lower surface of the support 4 so as to surround the opening 5, and the image receiving sheet 2 is heat-sealed so that the image receiving surface 2a faces this. This adhesive layer 6 has a weak adhesive force so that the image receiving sheet 2 can be peeled off by hand after transfer. Also, the adhesive F on the upper surface of the support 4
A pair of rails 7.8 are respectively connected to i6a to prevent excess developer that could not remain on the image receiving surface 2a from leaking out from the support 4 under the pressure of the developing roller. do. It should be noted that these rails 7.8 may also be joined under the support 4. Further, the developer pod 3 is bonded to the adhesive layer 9 on the upper surface of the support 4.

As shown in FIG. 2, in the image receiving member 1, an image receiving sheet 2 is joined with the image receiving surface 2a facing upward so as to respectively cover a plurality of openings 5 formed in a support body 4, and adjacent openings 5 A developer pod 3 is attached between them, so that a plurality of frames are in a continuous state. This long image receiving member 1 is in the form of a roll in consideration of its storage and loading into a photographing device. Then, it is installed in a photographing device in a roll form, and cut out one frame at a time from the cutting position indicated by a dashed line IO. By this cutting, the support body 4 is separated into a drawer part 4a that holds the developer pod 3 and a skirt part 4b that receives the excess developer. The rail 7.8 is located behind the skirt portion 4b so that the surplus developer stored thereon is not subjected to the pressing force of the developing roller.

As shown in FIG. 3, the image receiving sheet member 1a cut into pieces is stacked on the exposed photosensitive sheet member 15a to form a unit. After this unitization, the stacked image receiving sheet member 1a and photosensitive sheet member 15a are 1
Similar to conventional film units in which each frame is made into units in advance, the film is passed between developing rollers and subjected to the developing process.

During this development process, if the image receiving sheet member 1a and the photosensitive sheet member 15a are misaligned, a blurring image may occur, or the image transferred to the image receiving sheet 1a may be misaligned. . To prevent this, it is preferable to fix the leading end of the photosensitive sheet member 15a to the image-receiving sheet member 1a using adhesive tape 16a or by forming an adhesive layer on the drawer portion 4a.

Next, a photographing device using the image receiving member of the present invention will be explained. In FIG. 4, a photosensitive member 15 for recording a latent image is wound around a core 17, and a camera housing 20 is shown.
It is removably loaded into a core receiver 21 arranged above the core holder 21 . This photosensitive member 15 is attached to the guide roller 22. It passes through the return roller 23° and the guide roller 24 in sequence to reach the exposure position P.

The returning roller 23 is connected to the rond 25a of the air cylinder 25, and moves forward after cutting into sheets to return the tip of the photosensitive member 15 a little, thereby eliminating waste of the photosensitive member 15.

A photographing lens 27 having a lens shutter 26 is arranged in front of the exposure position P.
6, an image of the subject is formed on the photosensitive member 15 and recorded thereon as a latent image. In order to prevent external light from entering the photosensitive member 15 at the exposure position P, the exposure frame 2 is
A bellows 29 is attached to the lens 8 and the photographing lens 27. Further, in order to ensure the flatness of the photosensitive member 15 at the exposure position P, a plate 30 is provided. The exposure frame 2
A pair of photosensitive member feeding rollers 32 and 33 are arranged at the lower end of the photosensitive member 8, and are driven by a motor 34 to feed the exposed photosensitive member 15 in a fixed amount until the leading end reaches the photosensitive member leading end position P1.

In order to receive the latent image recorded on the photosensitive member 15 and form an image, the image receiving member 1 is wound around a core 18, and a core receiver 36 disposed below the camera housing 20.
It is removably loaded. The image receiving member 1 includes a pair of image receiving member feeding rollers 38.3 driven by a motor 37.

will be sent to. This image receiving member feeding roller 38°39
In order to prevent the developer pod 3 from tearing when the image receiving member 1 is pulled out, the parts separated from the developer pod 3 (both sides of the support 4) and the parts where the developer is not sealed (
It is composed of three narrow rollers so as to nip the rollers (the center of the support 4).

Since the image receiving member leading edge position P2 is located further than the photosensitive member leading edge position P1, the image receiving member feeding rollers 38, 39 are set to have a larger feeding amount than the photosensitive member feeding rollers 32, 33. Then, the photosensitive member 15 is placed on the image receiving member 1, and the adhesive tape 16a is pasted thereon. Then, as shown in FIG. 3, a cutter is attached to the photosensitive sheet member 15a and the image receiving sheet member 1a. It is cut off at 41.

The adhesive tape 16a is obtained by pulling out the tip of the adhesive tape roll 16 and cutting it into a predetermined length. That is, the adhesive tape roll 16 is pulled out by a certain length by a pair of knurling rollers 43 and 44 that have irregularities extending in the axial direction formed on the outer periphery to make it difficult to adhere. is sucked and held by the lower surface of the push plate 45, and is cut by the cutter 46 as it descends together with the push plate 45. This push plate 45 has a number of suction holes formed on its lower surface and is connected to a vacuum source (not shown). The adhesive tape 16a cut to a predetermined length is bonded onto the photosensitive member 15 and the image receiving member 1 because the adhesive surface formed on one side thereof is pressed against the photosensitive member 15 and the image receiving member 1 by the pressing plate 45. And adhesive tape 16a
After bonding, the push plate 45 releases suction and holding of the non-adhesive surface of the adhesive tape 16a, so only the push plate 45 rises.

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 drive lever 49 is rotatably supported by a shaft 50, and has a roller 51 attached to its tip. This roller 51 is in contact with the outer periphery of a cam 53 driven by a motor 52.

In front of the pushing plate 45, a pair of developing rollers 55 and 56 are provided.
are arranged, through which the photosensitive sheet member 15a and the image-receiving sheet member 1a pass in close contact with each other, and at this time the developer pod 3 is torn apart. These developing rollers 55
, 56 are provided with a constant nip force by a spring. In front of the developing rollers 55 and 56, there is a conveying roller 5.
7, 58 and pull-out rollers 59, 60 are arranged. The conveyance rollers 57 and 58 convey only the side portions of the opening 5 by sandwiching them in order to prevent uneven development. The developer pod 3 is connected to a pair of developing rollers 55.
Since a considerable pulling force is required when the paper is torn at 56, slipping is likely to occur if only the narrow transport rollers 57, 58 are used. Therefore, in order to increase the pulling force at the initial stage of drawing out the image receiving sheet member 1a, a pair of drawing rollers 59 and 60 are arranged to grip the leading end of the image receiving sheet member 1a and pull it out. If these pull-out rollers 59 and 60 are always close to each other, the image-receiving sheet 2
When the image-receiving sheet 2 arrives, it may get caught and cause uneven development, so please remove one of the pull-out rollers 6 before the image-receiving sheet 2 arrives.
0 is set aside. Note that the conveyance roller 57
．． 58 and the pull-out rollers 59 and 60 are attached to the adhesive tape 16.
It is driven by a motor (not shown) that rotates for a predetermined period of time after bonding a.

Next, the operation of the above photographing device will be explained. First, the roll-shaped photosensitive member 15 is loaded into the core receiver 21 and set at a position where its leading end is nipped by the photosensitive member feeding rollers 32 and 33. Further, the roll-shaped image receiving member 1 is mounted on the winding core receiver 36, and its tip end is the image receiving member feeding roller 3B,
Set it in the nipped position at 39.

When the start key is pressed after placing the subject in front of the photographic lens 27, the shutter 26 is operated and a latent image of the subject is recorded on a part of the photosensitive member 15 positioned at the exposure position P. After this photographing, the motor 37 is started, so the image receiving member 1 nipped by the image receiving member feeding rollers 38 and 39 moves along the support plates 40a and 40b, and its tip reaches the image receiving member tip position P2. A fixed amount is fed until the amount is reached. When this constant feeding is detected by the photo sensor, the motor 37 is stopped. The image receiving member 1
Since the conveyance rollers 57, 58 and the pull-out rollers 59, 60 also rotate for the same amount of time when the image receiving member 1 is sent out, the leading end of the image receiving member 1 is caught by them.

After the image receiving member 1 is fed in a fixed amount, the motor 34 is started, so that the photosensitive member feeding rollers 32 and 33 rotate to feed the photosensitive member 15 in a fixed amount. The leading end of the photosensitive member 15 moves along the top of the image receiving member 1 while being laterally changed in direction by a curved guide plate 62 . Then, when a sensor such as a photo sensor detects that the tip of the photosensitive member 15 has reached the photosensitive member tip position P1, the rotation of the motor 34 is stopped.

After the photosensitive member 15 has been metered and properly overlaid on the image receiving member 1, the knurling rollers 43, 44 are rotated to meter the leading end of the adhesive tape roll 16.

The non-adhesive surface of the leading end of the adhesive tape roll 16 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 530 rotates, the push plate 45 descends while sucking and holding the tip of the adhesive tape roll 16 on its lower surface, and the cutter 46 cuts the adhesive tape 16a into a predetermined length. The obtained adhesive tape 16a is pressed against the tip of the photosensitive member 15 and a part of the image receiving member 1 by the pressing plate 45 and adhered thereto.

After adhesion of the adhesive tape 16a, the valve provided in the vacuum source is switched and the inside of the push plate 45 is communicated with the atmosphere, so the suction and holding of the adhesive tape 16a is released and the push plate 45 is raised. to return to the initial position. By joining the adhesive tape 16a, the photosensitive member 15 is joined to the image receiving member 1 with its tip fully covering the developer pod 3.

Next, the cutter 41 is operated to cut the photosensitive member 15 and the image receiving member 1, separating them into the photosensitive sheet member 15a and the image receiving sheet member 1a to form an instant photographic unit 64 for one frame. After this cutting, the first general feed rollers 57, 58
Since the pull-out rollers 59 and 60 rotate, the leading end of the image-receiving sheet member 1a is caught by the pull-out rollers 59 and 60 and pulled out. Along with this, the photosensitive sheet member 1
The image receiving sheet member 5a and the image receiving sheet member 1a are pulled out while being in close contact with each other by the conveying rollers 57 and 58, with both sides being engaged. At this time, the developer pod 3 is connected to a pair of developing rollers 55,
56, the developer pod 3 is torn open and the developer contained therein is squeezed out between the photosensitive sheet member 15a and the image receiving sheet member 1a. Immediately after this,
One of the pull-out rollers 60 is retracted upward. The developer flowing out of the developer pod 3 enters the opening 5 of the support 4 and is spread out to a thickness corresponding to the thickness of the support 4. In addition, excess developer is removed by a pair of developing rollers 55 and 56.
The rear end portion of the photosensitive sheet member 15a and the skirt portion 4 are
It is pushed out between b and b. Since a rail 7.8 is provided on the lower surface of this skirt portion 4b, this rail 7.
．． Since the developing rollers 55 and 56 escape from each other by the thickness of 8, the excess developer stored on the skirt portion 4b is not pressurized by the developing rollers 55 and 56. Therefore, the surplus developer passes through the developing rollers 55 and 56 while remaining stored on the skirt portion 4b.

The developed instant photographic unit 64 is discharged onto the tray 65 with the image receiving sheet member 1a and the photosensitive sheet member 15a in close contact with each other via a sticky developer. Then, this instant photo unit 64 is
By leaving the image-receiving sheet 2 as it is for 0 seconds and then peeling off only the image-receiving sheet 2, an instant photograph with an image of the subject recorded thereon can be obtained.

After the cuffer 41 is activated, the motor 34 is reversed, and the air cylinder 25 is activated to advance the return roller 23. As a result, the leading end of the photosensitive member 15, which had been sent out to the position of the cutter 41, is returned to the position of the photosensitive member feeding rollers 32, 33, and the amount of the expensive photosensitive member 15 used can be saved.

Furthermore, when photographing, by operating the start key again, the photosensitive sheet member 1 is
5a and the image-receiving sheet member 1a are brought into close contact with each other and are discharged onto a tray 65 as an instant photographic unit 64.

The instant photo unit 64 is used for a certain period of time (60
Second) If you peel it off after heating (25-30℃), the finish will be uniform. For this purpose, it is desirable to heat the camera housing 20 for a certain period of time and then discharge it to the tray 65. Further, the back surfaces of the photosensitive member 15 and the image receiving member 1 are subjected to light shielding treatment to prevent fogging even if they are left in a bright room after deployment. If this light shielding process is omitted, the cost of the photosensitive member 15 and the image receiving member l can be reduced, but in this case, it is necessary to perform the development and fixing process 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 20 from light and temporarily store the instant photographic unit 64 inside the camera housing 20.

Further, another cutter is arranged under the photosensitive member feeding rollers 32 and 33, and after feeding the exposed photosensitive member 15 by a certain amount, this photosensitive member 15 is cut into the size of one frame. It is also possible to arrange the image receiving member at the tip position P2 and feed the image receiving member 1 by a certain amount while developing it, and then cut it into the size of one frame. In this case, there is no need to perform a return operation to save the photosensitive member 15, and the image receiving member is
There is no need to send a fixed amount. Furthermore, the conveyance roller 57
, 58 and the pull-out rollers 59, 60 can be driven in synchronization with the image-receiving member feeding rollers 38, 39, which has the advantage that the motor 37 can also be used.

〔Effect of the invention〕

The present invention having the above structure forms a plurality of frames in a row and cuts them one by one into a sheet form when used. Therefore, when shooting in large quantities, it can be used like a conventional packaged film unit. This eliminates the need to frequently replace banks, making photography extremely convenient. Further, since the present invention is suitable for large-scale 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, for these reasons and the elimination of the need for packs, it becomes possible to significantly reduce the shooting cost per piece.
