Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a storage device for an instant photographic device that stores a bonded body of a negative film and a positive sheet after developer has been spread, which is sent out from a peel-apart type instant photographic device. More specifically, the present invention relates to a storage device for an instant photographic device that can store a plurality of bonded bodies and has improved convenience.

[Conventional technology]

Traditionally, peel-apart type instant photography devices
The development process is carried out by exposing the negative film, overlapping it with the positive sheet, spreading the developer sealed in the pot, and leaving it in that state for a while.Then, by peeling off the negative film, the image is created. Finish forming.

In this development process, a period of time (approximately half or less of the development time, approximately 30 to 40 seconds) passes when light hits the unexposed silver halide on the photosensitive surface of the negative film without affecting the image. Until then, it is necessary to prevent the negative film from being exposed to light during the development process, so the development process is usually carried out in a dark place, or a light-shielding layer ( Measures have been taken, such as providing a color (black) or, if the positive sheet is a transparent sheet for OHP use, dispersing carbon in the developer to block light.

However, when a black light-shielding layer is provided on the back side of a positive sheet, a white layer is further coated on top of the black layer in order to improve the ease of writing on the back side and the appearance of the back side, so the color of the back side is not bright. There was an inconvenience that it turned gray and was not clean. Furthermore, if the thickness of the positive sheet is made thin, the black color on the back side will be visible on the image receiving surface, and the image on the image receiving surface will have a dull color as a whole, so there is also the disadvantage that the positive sheet must be made thicker. Furthermore, there were also disadvantages in that the cost increased due to the increased amount of coating on the positive sheet, and the manufacturing process became complicated, such as treatment for curling due to U8 humidity.

Further, in a developer in which carbon is dispersed, color reproducibility is deteriorated due to the carbon, and the manufacturing process is complicated since it is necessary to uniformly disperse carbon.

In addition, Japanese Patent Publication No. 63-289550 discloses a method of pasting a removable light-shielding paper on the back side of a positive sheet, but since it is necessary to paste the light-shielding paper on the back side of the positive sheet in advance, the supply cost is high. There were problems such as an increase in the amount of light and an increase in the amount of work required to peel off the light-shielding paper on the back side of the positive sheet after development.

For this reason, storage devices for instant photographic devices have been developed to avoid the problems caused by providing such supplies with light-shielding properties. As a storage device of a conventional instant photography device, for example, a dark box (storage device) is provided downstream of a developing roller to store a bonded body of a negative film and a positive sheet after developer has been spread, and the developing time ends in the dark box. Alternatively, as shown in Japanese Patent Laid-Open No. 64-26829, multiple discharge trays are provided and the storage and discharge of multiple bonded bodies is done within the development time of each bonded body. There is an elevator-type ejecting device that can perform random ejection based on the following.

[Problem to be solved by the invention]

However, according to the storage device of a conventional instant photography device, for example, in the method of storing the bonded material in a dark box until the development time is over, only one bonded material can be stored in the storage device (dark box). As a result, the dark box is occupied until the development time is over, making it impossible to perform continuous copying, resulting in a problem in that the copy processing speed of the instant photographic apparatus itself is reduced. Furthermore, in Japanese Patent Application Laid-Open No. 64-26829, although it is possible to perform copy processing continuously for the number of ejection trays, it is necessary to provide a storage and ejection control mechanism, a mechanism for raising and lowering the plurality of ejection trays, etc. As a result, the structure becomes complicated, leading to an increase in the cost of the instant photographic device itself, and there is also the problem that light shielding is insufficient because no light shielding means is provided.

The present invention has been made in view of the above, and a first object thereof is to be able to store a plurality of bonded bodies with a simple structure and to completely block light.

A second object is to eliminate the need to manage the development time and to ensure that the development process is completely completed by the time the product is discharged or taken out from the storage device.

A third object is to be able to automatically discharge the bonded body with a simple configuration without requiring a special drive mechanism or the like.

A fourth object is to be able to easily recognize whether or not a bonded body is stored and where it is stored in a dark box type storage device that can store a plurality of bonded bodies and is completely shielded from light.

[Means to solve the problem]

In order to achieve the above-mentioned first object, the present invention provides a storage device for an instant photographic device that stores a bonded body of a negative film and a positive sheet after the developer has been spread, which is sent out from a peel-apart type instant photographic device. A rotary storage means in which a plurality of storage parts for storing the bonded body of the negative film and the positive sheet are arranged in a radial and rotatable manner, and an outlet for taking out the bonded body of the negative film and the positive sheet from the rotary storage means. The present invention provides a storage device for an instant photographic device, which is equipped with a light-shielding means for blocking external light from irradiating the inside of the storage portion of the rotating storage means.

In addition, in order to achieve the second objective, in the above-described configuration, the rotating storage means transports the bonded body sent out from the instant photographic device to the position of the take-out port, taking a time corresponding to the development time of the bonded body. The present invention provides a storage device for an instant photographic device.

In addition, in order to achieve the third objective, in the above-mentioned configuration, an instant photograph is provided in which an outlet is provided at a position where the bonded body that has reached the position of the outlet falls from the storage part to the outside due to its own weight and is ejected. The present invention provides a device storage device.

Furthermore, in order to achieve the fourth objective, in the above-described configuration, at each position outside the device corresponding to the plurality of storage parts of the rotating storage means, it is displayed whether or not a bonded body is stored in the storage part. An object of the present invention is to provide a storage device for an instant photographic device provided with a display means.

[Effect]

In the storage device for the instant photography device of the present invention, the bonded body of the negative film and the positive sheet after the developer has been spread is discharged from the discharge port of the instant photography device main body to one of the radially arranged storage sections of the rotating storage means. be done. When the rotary storage means stores the bonded body in the storage section, the rotary storage means rotates and conveys the bonded body to the take-out port while shielding the bonded body from light using the light shielding means.

Further, the rotating storage means transports the bonded body sent out from the instant photographic device to the position of the take-out port, taking a time corresponding to the development time of the bonded body.

Further, in a configuration in which the outlet is installed downwardly below the rotary storage means, the joined body that has reached the outlet falls from the inside of the storage section to the outside due to its own weight and is discharged.

Further, in a structure in which a display means is provided at each position outside the device corresponding to a plurality of storage parts of the rotary storage means to display whether or not a bonded body is stored in the storage part, the display means Notifies whether storage is present and the transport position of the bonded body.

(2) Structure of a rotary sorter unit (storage device of the present invention) The structure of a rotary sorter unit 100, which is a storage device of the present invention, will be explained with reference to FIGS. 1(a) and 1(b).

The rotary sorter unit 100 is provided separately from the instant photographic device main body 300, and as shown in FIG.
It is placed near the outlet of the positive bonding body.

The rotary sorter unit 100 is roughly divided into a drum-shaped light-shielding housing 101, a rotor 102 that is rotatably housed inside the light-shielding housing 101 coaxially with the light-shielding housing 101, and a rotor 102 that is rotatably housed inside the light-shielding housing 101. It is composed of a discharge tray 103 that stores the negative/positive composite body discharged from the rotor 102, and a fixed housing 104 to which a light-shielding housing 101 and the discharge tray 103 are attached.

As shown, the rotor 102 is partitioned into a plurality of bins (accommodating portions) 106 by partition walls 105, and is intermittently driven to rotate in one direction via a motor, gear, etc. (not shown).

The light-shielding housing 101 is a bin 106 of the rotor 102.
This shields the negative/positive composite housed in the instant photographic device main body 30 so that external light does not irradiate it.
The negative/positive bonded body discharged from the rotor 102
A pair of rollers 107 transporting sheets one by one into a predetermined bin 106 of
and an opening (takeout port) 10 for discharging the negative/positive bonded body stored in the bin 106 to the discharge tray 103.
8, and is configured such that no external light is irradiated into the bin 106 of the rotor 102 except for the opening 108. Incidentally, the sensor S25 is a sensor that detects whether or not the negative/positive bonded body in the bin 106 is discharged onto the discharge tray 103 through the opening 108. In this embodiment, the opening 10
The size of the rotor 102 is made smaller than the size of the bottle 106.
When the bottle 10 is stopped, one bottle 10 is inserted into the opening 108.
Make sure that only 6 is located.

The fixed housing 104 forms a base portion of the rotary sorter unit 100, and when connected to the instant photographic device main body 300, the developing roller 32 of the instant photographic device is connected to the fixed housing 104.
A guide plate pair 10 that guides the negative/positive bonded body sent out from 5a and 325b to the roller pair 107 while maintaining a light-shielded state.
9, and a sensor S24 that detects the drive and stop timing of the roller pair 107 in order to completely store the negative/positive bonded body inside the bin 106.

Furthermore, as shown in FIG.
On the side surface of the rotor 102, an LED IIO is provided at a position corresponding to a plurality of bins 106 of the rotor 102 to display whether or not a negative/positive conjugate is stored in the bin 106. Whether or not a negative/positive bonded body is stored in this bin 106 may be detected by, for example, providing a negative/positive bonded body presence/absence sensor for each bin 106 (although this is not particularly limited). In this embodiment, the presence or absence of negative/positive bonded bodies in each bin 106 of the rotary sorter unit 100 is determined using software according to the method shown in FIG. 1(C).

First, a 16-bit shift register is prepared according to the number of bins of the rotary sorter unit 100 (16 bins in this embodiment). Here, each bin 106 from the bin 106 located at the storage opening (the position of the roller pair 107) to the opening 108 of the rotary sorter unit 100 is sequentially dealt with counterclockwise from the first focus (the least significant bit) of the shift register. let Therefore, the bin 106 located in the opening 108 is
This corresponds to the 13th pinpoint (hereinafter referred to as the output bit) of the shift register. Then, when a negative/positive zygote exists in the bin 106, the corresponding bit is set to "lJ", and when it does not exist, the corresponding bit is set to "0".

III in FIG. 1(C) is 1 in the rotary sorter unit 100.
This shows the state immediately after the negative/positive bonded body is stored, and the first bit corresponding to the storage opening is set to "1". Whether or not the negative/positive bonded body is stored in the bin 106 in this storage opening is determined using the detection signal of the sensor S24 described above.

112 indicates that the rotor 102 of the rotary sorter unit 100 is 1
The state of the shift register is shown when the shift register is rotated by the amount corresponding to the bin, and by shifting the shift register one position to the left from the state of 112, the center is set to 1 corresponding to the position of the bin 106 having a negative/positive bond. bit is moved.

113 indicates the state of the shift register when the rotor 102 has further rotated by an amount corresponding to one bin from the state of 112.

114 is the bottle 10 whose storage opening is the second negative/positive bonded body.
6, and similarly to (1), "1" is placed in the first bit of the shift register.

In this way, each bin 1 of the rotary sorter unit 100
The presence or absence of a negative/positive conjugate in 06 corresponds to "1" and "0" of each bit of the shift register, respectively.

Next, when the shift register advances and the position of the exit bit is set to "1" as shown at 115, in other words, the negative/positive bonded body has been rotated and conveyed to the opening 108. Let me explain the case. Although the details will be described later, in this embodiment, the copying process of the instant photographic apparatus main body 300 is continued until the negative/positive bonded body conveyed to the position of the opening 108 falls from the bin 106 to the discharge tray 103 and is completely discharged. Operation and rotation of the rotor 102 are prohibited. Here, whether or not the negative/positive bonded body has been completely discharged is determined by a sensor S25 provided in the opening 108.

When the discharge of the negative/positive bonded body is detected via the sensor S25, the discharge port bit is set to "0" as shown at 116. This extraction port bit "0" cancels the above-described copying operation of the instant photographic apparatus main body 300 and prohibition of rotation of the rotor 102.

The operation of the rotary sorter unit 100 will be described in detail in section (2) Control operation of the control unit (control operation of the rotary sorter unit), which will be described later, but the general operation will be described below to make the explanation easier to understand.

The negative/positive bonded body (details will be described later) on which the developer has been spread by the developing rollers 325a and 325b is discharged to the rotary sorter unit 100 side along the pair of guide plates 109 as the developing rollers 325a and 325b rotate. The sheets are then carried into the bin 106 one by one by a pair of rollers 107. The rotor 102 with the bin 106 rotates every 7.5 seconds by an angle corresponding to one bin (in this example, 22.5 seconds).
5°) counterclockwise. An opening 108 is provided at a position rotated by 12 pins (270°) from the carry-in position (that is, the position of the roller pair 107), and the negative/positive bonded body is rotated by 12 pins before opening 108. The paper slides down to the discharge tray 103 due to its own weight and is discharged.

In other words, after 90 seconds (7.5 seconds x 12 rotations) have elapsed, the paper is discharged from the opening 108 to the discharge tray 103 . The elapsed time of 90 seconds until discharge at this time corresponds to the development time when normal photographic paper is used as the positive sheet. In addition, when OHP transparent paper is used as the positive sheet, the development time is 240 seconds, so the rotor 102
By rotating every 20 seconds, the developing time for transparent paper for P is controlled to be 0) (240 seconds for P transparent paper), and the developed negatives and positives are placed on the output tray 103. It is configured to discharge the zygote.

■Configuration of positive sheet assembly In this example, the positive sheet (image-receiving sheet) is used as a positive sheet assembly by attaching accessories such as a pond containing developer and a trap mask for retaining excess developer after spreading. do.

FIGS. 2(a), 2(b), and 2(c) show the configuration of the positive sheet assembly 200, which includes a black leader 202 attached to the tip of the positive sheet 201 on the image receiving surface side. , a box 2 that houses the developer 203a and is attached to the leader 202.
03 and the image area of the positive sheet 201 (a in FIG.
A tip mask 2049 and both side masks 205 . It also includes a trap mask 206 and rail members 207 attached to both side masks 205.

Although the details will be described later, the developer 2 that has flowed out from the bot 203
03a is the rail member 207 and both side masks 205
This structure allows the film to be uniformly spread on the positive sheet 201 to a thickness that is approximately the same as that of the film.

The developer 203a is contained in the pond 203 in an amount larger than that required for image formation so that the developer 203a is sufficiently distributed to the rear end of the image area. After the excess developer 203a is uniformly spread to the rear end of the image area, it is transferred to a trap mask 206 (portion D in FIG. 2(a)) and a negative film 210 (described later) (portion Do in FIG. 2(d)). It is stored between. This prevents excess developer 203a from spilling out into the apparatus, adhering to the developing roller, the conveyance path, etc., and contaminating them.

The IJ-dar 202 has a positive sheet type identification code indicating the type of positive sheet (for example, photographic paper type, transparent paper type, etc.) in three mark portions M1. It is formed by M2°M3. Specifically, the mark portions Ml, M2 . M3
For example, a positive sheet type identification code may be formed by punching holes or the like and forming a positive sheet type identification code by combining the presence or absence of the size, or it may be formed by printing with a reflectance different from that of the leader 202. In this embodiment, the mark portion M1. M2. Form M3. As described above, since the body 203 is pasted on the leader 202, the mark portion Ml is formed as shown in FIG. 2(C).

M2. If M3 has a hole, the hole portion will be covered by the bond 203. Therefore, the +J-goo 202 is made black in color and contrasted with the bond 203 color (usually white) to improve detection accuracy.

(2) Structure of Negative Film and Negative Film Cartridge In this embodiment, as shown in FIGS. 2(d), 2(e), and 2), a negative film 210 wound into a roll is used.

The negative film 210 is made of a long photosensitive strip material (for example, 36 images can be taken), and is wound into a roll with the latent image forming surface (photosensitive surface) inside, as shown in FIG. The film is stored in the negative film cartridge 211.

The negative film cartridge 211 is resin-molded into a cylindrical shape containing the rolled negative film 210.
In order to facilitate molding and loading of the negative film 210, the structure is divided into two planes including the axis.

As shown in the figure ((a), Ql), the negative film cartridge (upper container 211a and lower container 21
Fitting portions 212 and 213 for coupling, and a negative guiding portion 214 and a negative feeding portion 215 for feeding out the negative film 210 are formed in the divided portion of lb), respectively. The fitting parts 212 and 213 are formed in such a manner that the fitting part 212 covers the fitting part 213, thereby preventing the negative film 210 from being exposed to light due to the entry of ambient light. Similarly, in order to prevent disturbance light from the negative feeding section 215, the negative guiding section 215
A light-shielding elastic member 216 (for example, mylar with flocked cloth attached) is arranged inside the film 14, with one end affixed to the upper container 211a and the other end contacting the negative film 210 with its own elastic force. ing.

Negative film 210 in negative film cartridge 211
When storing the lower container 211b, the tip of the roll-shaped negative film 210 is inserted into the negative feeder 21.
Place it so that it protrudes outward by a few mm. after that,
The upper container 211a is placed on the upper container 211a, and the fitting parts 212 and 213 are fitted to connect the upper and lower containers 211a and 211b.

The connection between the upper and lower containers 211a and 211b is not limited to the above-mentioned method, and for example, screws, heat sealing, or the like may be used. Note that a foot 217 is provided at the bottom of the lower container 211b to ensure that the negative film cartridge 211 is mounted in a fixed position in the main body of the apparatus.

Further, on the side surface of the container 211a, there is a mark M4 indicating the type of negative film 210, etc. M5. M6 (negative film type identification code) is provided.

Incidentally, the front surface of the negative film 210 has photosensitivity, but has a light-shielding property against external light (irradiation) from the back surface. The roll-shaped negative film 210 is placed in a bright room (semi-dark room).
The negative film cartridge 21 is in the state shown in FIG.
1, the shaded areas (the leading and trailing ends of the long film) are exposed. Other areas are not exposed to light if they are tightly wound. A latent image (image) cannot be formed in the exposed area, and the area becomes wasted. The negative film 210 is expensive because it uses silver salt, and the waste of this part cannot be ignored. Therefore, in this embodiment, as shown in FIG. The leading end portion 218 and the trailing end portion 219 are pasted. Therefore, this can prevent the leading and trailing ends from being exposed to light.
Moreover, the negative film 210 can be constructed at low cost.

In addition, as shown in FIG.
Pull-out roller pair 312a that pulls out the negative film 210
, 312b is provided, and a notch 220 is provided to fit with the
When the negative film cartridge 211 is installed in the main body of the apparatus, the negative film 210 is reliably nipped by the pair of pull-out rollers 312a and 312b.

■Configuration and operation of the entire device Figure 3 shows the overall configuration of an instant photographic device main body 300 that uses peel-apart type instant photographic film.

The optical system unit 301 includes a contact glass 303,
A first traveling body 304 consisting of a first mirror and a light source, and a second
A second traveling body 305 consisting of a mirror and a third mirror, and a lens 306. It is composed of a third traveling body 307 consisting of a fourth mirror and a fifth mirror, and a sixth mirror 308.

Here, the light source included in the first traveling body 304 includes a fluorescent lamp 3
73 (details will be described later) is used, and a document placed face down on the contact glass 303 is placed on the contact glass 303.
Irradiate while scanning parallel to 3. At this time, the second traveling body 305 is scanned in the same direction at half the speed of the first traveling body 304, so that the optical path length is kept constant.

In addition, by moving the lens 306 and the third traveling body 307, the magnification and conjugate length are adjusted during zooming.

As shown in the figure, the reflected light from the original is transmitted to the first. Second. as well as.

It is reflected by a third mirror, and is further reflected by a lens 306. 4th, 5th. After passing through the sixth mirror, the light is subjected to slit exposure in the exposure section 111A.

The transport unit 302 carries a photosensitive negative roll film (
Negative film 210) A feeding unit, a negative film cutter unit that cuts the fed negative film 210, a negative film transport/exposure unit that transports and exposes the negative film 210, a positive sheet assembly transport unit, and a developing unit. configured.

The transport operation of the negative film 210 (not shown) will be explained below, and the configurations of the negative roll film feed section, the negative film cutter section, and the negative film transport/exposure section will be shown in detail.

The negative film 210 stored in a roll in the negative film cartridge 211 is pulled out by a pair of pull-out rollers 312a.
, 312b, the rotary blade 313a and the fixed blade 313b
The intermediate roller pair 315a is conveyed onto the guide plate 314.

315b. When the leading edge of the conveyed negative film 210 is detected by the sensor S1 at the exposure position A (or after a predetermined period of time after detection), the first traveling body 304 and the second traveling body 305 start scanning, and the negative film 210
After being nipped by the pair of intermediate rollers 315a and 315b, exposure and latent image formation are performed at exposure position A on the guide plate 314.

Here, if the conveying speed of the negative film 210 during exposure and latent image formation is vN, the traveling speed of the first traveling body 30゛4 is Vl, and the copying magnification is m, then the negative film 210
The conveyance speed VN of 0 is controlled according to the relationship: Vl = VN x 1/m.

The exposure position A is a flat surface across the slit area,
And a pair of pull-out rollers 312a.

312b and the nip height of the pair of intermediate rollers 315a, 315b, or higher than that. Furthermore, the circumferential speeds of the pair of intermediate rollers 315a, 315b and the pair of pull-out rollers 312a, 312b are almost the same, and after a predetermined period of time after the negative film 210 is detected by the sensor S1 (after being nipped by the pair of intermediate rollers 315a, 315b,
Alternatively, at the timing when exposure is started, the driving of the pair of pull-out rollers 312a and 312b is stopped and becomes free with an appropriate load. As a result, negative film 21
0 on the exposure position A, and guide plate 3.
The optical path length to the negative film 210 surface and the transport speed can be kept constant.

Negative film 21 on which a latent image is formed by exposure over a certain length
0 is temporarily stopped, and then the rotating blade 313a changes to the fixed blade 3.
By rotating while contacting 13b, the sheet is cut into sheets. The stop timing of the negative film 210 is determined by counting the time t after the sensor S1 detects the leading edge of the negative film 210.

Therefore, the rear end portion of the cut negative film 210 is not exposed to light and no latent image is formed (in other words, exposure and latent image formation cannot be performed). Specifically, at least the distance from the exposure position A to the tip of the fixed blade 313b (this distance is defined as G)
The rear end portion of the negative film 210 corresponding to the above is in an unused state, that is, a portion that is unnecessarily wasted. Therefore, the exposure position is adjusted so that this distance G is smaller than the distance D" from the rear end of the positive sheet assembly 200 to the rear end of the image area to be transferred onto the positive sheet 201 (see FIG. 2(d)). A and cutters (rotary blade 313a and fixed blade 313b) are arranged to reduce wastage of unnecessary portions (rear end portions) of the negative film 210 that are not used for image formation.

Similarly, the leading end of the cut negative film 210 is also moved from at least the exposure position A to the intermediate roller pair 315a, 315.
Exposure and latent image formation cannot be performed over a distance longer than the distance b (this distance is defined as H), but the distance H is the latent image part where an image is formed on the negative film 210 from the leading edge of the negative film 210. The exposure position A and the intermediate roller pair 315 are adjusted so that the distance to the tip is smaller than the distance C' (see FIG. 2(d)).
a.

315b makes it possible to reduce wastage of the negative film 210.

Furthermore, by cutting the negative film 210 after the exposure is completely completed as described above, it is possible to avoid changes in the transport speed due to the impact of cutting, for example, compared to the case where the negative film 210 is cut during exposure. , stable transportation is possible.

The cut negative film 210 is transported by a pair of rollers 316a,
After being turned about 180 degrees by guide members 316b and 317, it is guided by guide plates 318a and 318b, and is further conveyed by rollers 320 until its tip reaches a pair of rollers 321 (in a stopped state here). be done.

Next, the transport operation of the positive sheet assembly 200 will be explained, and the configuration of the positive sheet assembly transport section will be shown in detail. Actually, this positive sheet assembly 200
This transport operation is performed before the above-described transport, exposure, and cutting operations of the negative film 210.

The positive sheet assembly 200 includes a negative film 21
Unlike 0, it is not photosensitive, so it can be inserted from outside the device. In this embodiment, the positive sheet assembly 200 is moved one step toward the left side in the figure along the guide plate 311 at the lower right of the main body of the apparatus.
The configuration is such that the sheets are manually inserted one by one. Therefore, there is no need for a paper feeding/separating device, a paper feeding power center, etc., and the apparatus can be made compact and inexpensive.

When the positive sheet assembly 200 is inserted along the guide plate 311 and both side guides (not shown) and its tip is detected by the sensor S5, the insertion roller pair 3
22 rotates. The rollers of the insertion roller pair 322 are positive sheet assembly! It is arranged so as to grip only both ends outside the bond 203 so as not to crush the developer bod 203 (see FIG. 2(a)) attached to the tip of J-200. The positive sheet assembly 200 is conveyed between the guide plates 323a and 323b by the insertion roller pair 322, and then stopped. This stop timing is determined by the sensor S6
is obtained by counting the time t' from the time when the leading edge of the positive sheet assembly 200 is detected.

Further, as shown in the figure, the conveyance path of the positive sheet assembly 200 is bent at at least one place, so that external light does not directly enter the machine from the insertion opening of the positive sheet assembly 200 and expose the negative film 210. It is prevented as follows.

The inserted positive sheet assembly 200 stops at a predetermined position and enters a standby state, allowing printing operation.

Here, when a predetermined print switch is pressed, the above-described transporting, exposing, and cutting operations of the negative film 210 are executed. The negative film 210 that has come into contact with the stopped roller pair 321 is moved by the guide plate 319 and the guide plate 318b.
It is deflected by a certain amount by the conveying force of the roller pair 320 between them. After a predetermined amount of the negative film 210 is bent, the roller pair 3
21, it is conveyed between the guide plates 324a and 324b. The start of rotation of the roller pair 321 is determined by counting the time from when the sensor S3 detects the leading edge of the negative film 210.

By bending the negative film 210 in this way,
Skew correction is performed by bringing the leading edge of the negative film 210 into the nip between the roller pair 321. The negative film 210 conveyed by the rotation of the roller pair 321 is transferred to the sensor S.
4, the leading edge is detected, and the developing rollers 325a, 325
It is transported to nip b. Based on the timing from the detection by the sensor S4, the insertion roller pair 322 first rotates and abuts the positive sheet assembly 200 against the stopped developing rollers 325a and 325b, and skew correction is performed in the same manner as the negative film 210. After that, the developing roller 32
5a and 325b start rotating.

Next, the positive sheet assembly 200 waiting at a predetermined position is first conveyed, and then the leading edge of the negative film 210 is transferred to the developing roller 320 by the rotation of the roller pair 321.
a and 325b, and both develop rollers 3
It is transported at circumferential speeds of 25a and 325b. At this time, a deviation J occurs between the leading edge of the positive sheet assembly 200 and the negative film 210, but this deviation J is controlled to be at least smaller than C in FIG. 2(a).

This makes it possible to shorten the length of the negative film 210 that is cut by the amount of this deviation J, compared to a type in which the leading edge of the negative film 210 and the leading edge of the positive sheet assembly 200 are aligned and conveyed. can.

Finally, Fig. 4(a), (b), (C), and Fig. 5(a).

(b), (c), (d), (e), (f),
(The developing operation will be explained with reference to the following, and the configuration of the developing section will be shown in detail.

The developing roller 325a has a shaft 3 fixed to the developing side plate 341.
The developing roller 325a is rotatably supported by a pressure lever 342 that rotates around the developing side plate 3.
41 so as to be rotatably supported.

349 shown in Figures 4(C) and 5(C) and (d)
and 350, when the developer is spread, the developer 2 is applied from both ends of the negative film 210 and the positive sheet assembly 200.
03a protrudes and the developing roller 325a.

The regulating member 349 is rotatably supported around a bin 352 fixed to the developing side plate 341.
50 is fixed to the developing side plate 341. Further, the regulating members 349 and 350 are both developing rollers 325a and 325b.
It enters the groove 355 provided in the.

Figures 5 (a), (b), and (C) show the state of the developing section when the main body of the apparatus is in a standby state. Both the developing roller spacing cam 346 fixed to the cam shaft 348 and the spacing cam 347 of the regulating member 349 are connected to the cam follower 3 rotatably supported by the pressure lever 342.
44 and the lever part 349a of the regulating member 349, and the developing roller 325a is separated from the spring 345.
The developing roller 325b is pressurized by the developer roller 325b. Also,
The regulating member 349 is held in a pressurized state by a spring 351. As shown in FIG. 5(C), the regulating member 349 is configured to maintain a gap P between it and the regulating member 350 when pressurized.

On the other hand, the camshaft 34'8 to which the cams 346 and 347 are fixed can be rotated by a quarter rotation by a spring clutch (not shown). The positions of the cams 346 and 347 at this time (that is, the standby position) are detected by a predetermined sensor.
47 is not in the standby position, it is controlled to be in the standby position.

When the positive sheet assembly 200 is inserted along the guide plate 311 in FIG. 3 and detected by the sensor S5, the camshaft 348 is moved 1/2 in the counterclockwise direction (direction shown in the figure).
It rotates four times and becomes the state shown in Fig. 5 (a). In this state, the lever part 349a is pushed by the cam 347, the regulating member 349 is separated from the regulating member 350, and the gap is widened. With this, the positive sheet assembly 200
The toner is reliably conveyed to the nip portion between the developing rollers 325a and 325b without hitting the regulating member 349 and stopping.

Next, the aforementioned negative film 210 is transported, the developing rollers 325a and 325b rotate, and the negative film 210 is rotated.
10 is inserted between the regulating members 349 and 350, the camshaft 348 further rotates 1/4 in the counterclockwise direction to the state shown in FIG. 5(e), and the regulating member 34
9 is in a state with a gap P (here, a state in which the developer is restricted from protruding) as in FIG. 5(C). The rotation timing of the camshaft 348 to shift to this protrusion regulation state is determined by counting the time after the sensor S4 detects the leading edge of the negative film 210.

As described above, when the spreading of the developer 203a by the developing rollers 325a and 325b is completed, the cam shaft 348 further rotates by 1/4 to reach the state shown in FIG.
6 and the cam follower 344 come into contact with each other, and the developing roller 325
a is spaced apart from the developing roller 325b to create a gap between the rollers necessary for storing excess developer 203a.

The trap mask 206 is separably bonded to the positive sheet 201, and is bonded to the negative film 210 side by the adhesive force of the spread developer 203a, and can be easily removed by peeling off the positive sheet 201 from the negative/positive bonded body. separated into

As shown in FIG. 2(a), the length of the bot 203 in the width direction on the positive sheet assembly 200 is set to be equal to or equal to the width of the image area so that it does not tear due to pressure contact with rollers etc. during conveyance. It's shorter. For this reason, bond 2
After 03 is cleaved at part F, it takes some distance (distance indicated by E in the figure) before it spreads into the image area. Also,
As mentioned above, the deviation J when aligning the negative film 210 and the positive sheet assembly 200 is caused by the gap F from the tip of the positive sheet assembly 200 to the cleavage part F of the bond 203.
It is sufficient to make the distance 1c shorter than the distance 1c from the

The timing for releasing the pressure contact of the developing roller 325b (that is, the separation of the developing roller 325a) is determined. Also, a jam is determined based on the time from when the registration roller 321 is rotated until when the negative film 210 is detected. Specifically, it consists of an infrared reflective sensor.

The sensor S5 detects insertion of the positive sheet assembly 200. When the tip of the positive sheet assembly 200 is detected by the sensor S5, the mark portion Ml of the positive sheet assembly 200 is detected.

The sensor S8 senses the back side of the negative film 210 to detect the presence or absence of the negative film 210.

At the same time, the leading and trailing ends of the negative film 210 (
light-shielding papers 218 and 219). For this reason, it is configured with an infrared reflective sensor, and an A/D converter reads the output of the phototransistor that receives the reflected light, and detects the difference in output.

The sensor SIO includes mark portions Ml, M2. Read M3 (positive sheet type identification code). Specifically, the infrared reflective sensor is attached to the mark portions Ml, M2 . Three sensors (Sensor S 10-1.10-2.1O-3) are used to match the number of M3.

The sensor S20 consists of a photodiode and an operational amplifier, and detects the brightness of the fluorescent lamp 373 with the photodiode, converts it into a voltage signal with a current/voltage conversion circuit and an amplifier circuit, and converts it into a voltage signal.
This value is input to the /D converter, taken into the CPU, and used to control the light amount of the fluorescent lamp 373.

The sensor S21 includes a thermistor and detects the temperature of the fluorescent lamp 373. Since the fluorescent lamp 373 has temperature characteristics in light intensity and spectral distribution, its usable temperature range is limited.

Drives solenoids, etc. and controls operation parts.

Note that the other configurations are only shown in the drawings and will not be described.

[Phase] Control operation of the control section (control operation of the instant photographic apparatus main body) Based on the above configuration, the control operation of the control section 400 of the instant photographic apparatus of this embodiment will be explained in detail.

The control operation of the control unit 400 is shown in the main flow shown in the flowchart of FIG. 11(a) and in FIG. 11(b).

4 shown in the flowcharts of (C), (d), and (e).
The interrupt processing routine consists of one interrupt processing routine and a plurality of interrupt processing routines for controlling the rotary sorter unit, which will be described later.

Here, the control operations related to the copying operation of the instant photographic apparatus main body, specifically, FIGS. 11(a) and 11(b).

The control operations shown in flowcharts (c), (d), and (e) will be explained.

The main flow mainly performs sequence control of the machine and responses to the operator.

First, when the power is turned on, the CPU is initialized.

Memory initialization 2 Initialization processing such as initialization of peripheral ICs is executed (401). Next, a machine initialization process (402) for the scanner, lens, developing roller, cutter, etc. is performed, and an operation by an operator is awaited in a standby process (403). Thereafter, copying operation processing (404) or serviceman mode processing (405) is executed depending on the operator's operation.

The interrupt processing routine is shown in (b), (C), (
d), 2.5m5ec interval shown in (e),
It consists of four routines: motor encoder, fluorescent lamp lighting, and scanner motor. At the 2.5IISeC interval, various Ilo checks and settings are performed, and time-related operations are performed at the same time. The other three operate only when the motor or fluorescent light is on, and control servos and the like.

Hereinafter, each process of the main flow described above will be specifically explained in order.

FIG. 12 shows a flowchart of machine initialization processing. If there is no developing roller, +24V will drop and the power will not work. Therefore, the sensor S14 is used to detect the presence or absence of the developing roller (406). Fluorescent lamp heater 37
4 to 0N (407), and the mechanisms whose states change, such as the scanner, lens, and mirror, are initialized (40B). At this time, if the negative film 210 is on the conveyance path,
Cutter initialization is not performed (409°410)
. Furthermore, if the positive sheet assembly 200 is on the conveyance path, it is automatically discharged (411, 412).

After that, initialize the developing roller (413),
Once the fluorescent lamp 373 has warmed up, the process ends (414).

FIG. 13 shows a flowchart of standby processing.

The standby process basically checks the condition of the machine (jam, door opening/closing, whether a negative film cartridge is loaded, etc.), accepts or accepts the print key depending on the conditions, and accepts the job for the next copying process. pass it on. First, negative film 2
Check whether the negative film 210 is detected by the sensor on the conveyance path No. 10 (415) L, the negative film 21
If 0 is detected, it is judged as a jam and the jam display is turned on.
and an error flag is set (416). Similarly, check the open/closed status of the door, and if the door is 0PEN, turn ON the door 0PEN display and set the error flag (
417, 418), check the presence or absence of the developing roller,
If there is no developing roller, a developing roller absent display is displayed and an error flag is set (419, 420). Thereafter, in steps 421 to 424, inputs using the magnification key and the density key of the operation unit 500 are accepted, and the corresponding operations are performed. At this time, by pressing some predetermined keys, a transition is made to serviceman mode processing (details are omitted). Next, the 3-bit black and white code (negative film type identification mark) indicating the type of negative film 210 provided on the side of the negative film cartridge 211 is read.
The presence or absence of the negative film cartridge 211 and the type of negative film 210 are detected, and the negative film cartridge 2
11 and the type of negative film 210 (
42'5). After that, if an error flag is set in the above step, a message etc. corresponding to the error is displayed and the error flag is initialized to zero (426
, 427).

Next, if the negative film cartridge 211 is present (428L, it is determined whether the negative film 210 is present or not and whether it is in the film section (429). As described above, the negative film 210 is wound into a roll and placed inside the negative film cartridge 211. The sensor S8 checks the presence or absence of the negative film 210, and has light-shielding papers 218 and 219 attached to its leading and trailing ends. Also distinguish between the film part and the light-shielding paper part.

Specifically, the sensor S8 consists of an infrared LED and a phototransistor that checks the reflected light, and the reflected light is input to the A/D converter of the CPU,
255) data. negative film 21
If there is no 0, there is no reflected light, so the data will be almost zero, and if the back side (black) of the film part is detected, a small amount of light will be reflected, for example 200 to 12
The value is approximately 0. On the other hand, in the case of light-shielding paper, the reflectance is higher than that of the back side of the film portion, so the value is 210 or more, and the CPU can determine whether there is a negative film 210 and whether it is a film portion.

If the above judgment is a light-shielding paper, in other words, if it is not a film part, the light-shielding paper is ejected (430, 431)
. When the light-shielding paper is ejected, if the light-shielding paper is at the leading edge, the film portion is detected next, so the conveyance is stopped there, and the film is cut with a cutter and then ejected from the apparatus. Furthermore, if the light-shielding paper is at the rear end, it is detected that there is no film, so the sheet is ejected as is. On the other hand, if it is not the light-shielding paper, the process advances to step 432. If there is no negative film 210,
The absence of negative film 210 is displayed (433), and in step 434, a positive sheet insertion check and its corresponding operation (
(details will be described later). If the negative film 210 is present, the no negative film display is set to 0FFL, and the positive sheet standby flag (a flag indicating that the positive sheet is ready) is checked (435, 436).

If it is standby, check whether the positive sheet ejection switch is ON (437) L; if it is ON, execute the positive sheet ejection operation (43B) L; if not ON, wait for the print key to be turned ON and end the process (439) ).

Note that the positive sheet ejection switch is turned on by pressing the positive sheet ejection switch 505 of the operation unit 500, and thereby the positive sheet assembly 20
Even after inserting 0 and completing all copy preparations, the operator is free to automatically eject the positive sheet assembly 200.

FIG. 14(a) shows a flowchart of the positive sheet insertion check and its corresponding operation routine (step 434 in FIG. 13). This routine includes detection of positive insertion by the sensor S5, and detection of the positive sheet type identification code (mark part ML of the positive sheet Anocene Free 200) by the sensor 310.
M2. M3), and if the positive sheet type and negative film type are -4, the positive sheet assembly 200 is conveyed to a predetermined position in front of the developing roller and stopped. If they do not match, the device This is a routine to discharge it to the outside.

When the positive sheet assembly 200 is inserted from the positive sheet insertion opening of the apparatus, the insertion of the positive sheet assembly 200 is detected by the sensor S5. At the moment of this positive insertion detection, as shown in FIG. 14(b), the sensor S1
Mark part Ml at position 0.

M2. M3 is located so that sensor S
5, the positive sheet assembly 200 has arrived at a predetermined position, in other words, the positive sheet type identification code (mark portion M1.M2.M
3) It can be determined that reading is possible. Therefore, if the positive insertion detection is not ON, the positive insertion detection flag is set to 0 and the process ends (440.4
41).

When the positive insertion detection is ON, it is determined whether or not this detection is the detection of the leading end of the positive sheet assembly 200 using the positive insertion detection flag. In the flowchart of this embodiment, when the positive insertion detection is ON and the positive insertion detection flag is O, it means that the positive sheet assembly 200 has been detected for the first time, in other words, the leading end of the positive sheet assembly 200 has been detected. shows. Therefore, step 442
If NO, the positive sheet type identification code is read and the positive insertion detection flag is set to 1, indicating that the positive sheet type identification code has been read (44
3).

Here, the positive sheet type identification code is shown in Figure 14 (C).
As shown in the figure, the mark portions Ml, M2 . It is formed with a black and white pattern of M3, and this mark portion M1. M2.
The type of positive sheet is assigned to each M3 and coded. However, the mark part Ml.

M2. For M3, a code with an all-white or all-black pattern is not used as an invalid code. This allows, for example,
In other words, when the positive sheet assembly 200 is turned over or inserted with the front, back, left, and right sides reversed, the sensor 31
If the detected zero pattern is an all-white or all-black pattern, erroneous insertion of the positive sheet assembly 200 can be detected.

Therefore, mark portion M1. M2. If M3 has an all-white or all-black pattern, use the positive sheet assembly 20.
0 is determined to have been inserted incorrectly, R photographic paper 1 is displayed on the operation unit 500, and a buzzer sounds to warn of incorrect insertion (4
44,449) and ejects the positive sheet assembly (450). On the other hand, mark portions Ml, M2. If M3 is not an all-white or all-black pattern, the presence or absence of a negative film cartridge is determined (445). Here, if there is a negative film cartridge 210, it is determined whether the type of negative film and the type of positive sheet match (446
)L, if they match, stop the positive sheet assembly 200 at a predetermined position in front of the developing roller, set the positive standby flag to 1, and end the process (447, 448)
. If the type of negative film and the type of positive sheet do not match, it is determined that the positive sheet assembly 200 has been inserted incorrectly, and "Photographic paper" is displayed on the operation unit 500, and a predetermined buzzer sounds to warn of incorrect insertion. (444゜4
49). On the other hand, if the negative film cartridge 210 is not loaded, the positive sheet assembly 200 is stopped at a predetermined position in front of the developing roller, the positive standby flag is set to 1, and the process ends (447, 448).
).

FIG. 15 shows a flowchart of copying operation processing. When the print key is pressed, first, it is determined whether the mode is 35mm project mode or not (451), and if the mode is not 35mm project mode, the fluorescent lamp is turned on (452).
, if it is 35mm project mode, step 453
Proceed to.

The main motor, negative pull-out clutch, and negative feed clutch are set to 0N (453) to start conveying the negative film 210, and when the leading edge of the negative film is detected by the negative film leading edge detection (sensor 31), the magnification and mode are set. Start the scanner at the appropriate timing (454, 456
). If the leading edge of the negative film is not detected, a non-feeding jam check is performed, and if the leading edge is not detected within a predetermined time, it is determined that a non-feeding jam has occurred and the process proceeds to the 459L jam processing routine (details are omitted).

Negative film intermediate detection (1), (2) (sensor S2
．． Sensor S3) performs a JAM check in the same way (45
6°457.460,461). After the negative film 210 is fed to the negative film intermediate detection (2), the conveyance is stopped when the length of the negative film 210 - Autumn Equinox is fed out, the scanner is returned (rotated in reverse), and the cutter is rotated. After cutting the negative film 210, the feeding of the negative film 210 is restarted (458-464).

After the conveyance is restarted, the registration roller is rotated when the negative film 210 hits the registration roller and the leading end thereof is bent to some extent. In other words, skew correction is performed by starting rotation of the registration rollers at a predetermined timing (465). The negative film 210 that has passed through the registration rollers is detected by the negative pre-development detection (sensor 34),
After a certain period of time, rotate the developing roller and perform development (
466, 468). At this time, turn on the resist clutch.
A JAM check is performed in the time since then, and if it is not detected by the negative pre-development detection even after a certain period of time has elapsed, it is determined that there is a resist jam (467). Further, the negative pre-development detection (sensor 34) detects that the rear end of the negative film 210 has passed, and after a predetermined time has elapsed, the developing roller is stopped and the developing roller is set in a separated state (469, 470
). From this point on, a development time notification timer is started (471). Although not shown in the flowchart, the presence or absence of a negative is detected (sensor S8) during the above copying operation.
When the data indicates the value of the light-shielding paper, the CPU determines whether the length of the negative film 210 that has been fed out so far is long enough to form an image (corresponding to l in FIG. 2(d)). , the copying operation is interrupted and the negative film 210 and positive sheet assembly 200 are discharged, respectively. On the other hand, if it is longer, the cutter operation is omitted and the negative film 2 is cut.
The entire rear end of 10 is attached to the negative film cartridge 211.
Execute the copying operation according to the flowchart while drawing from. Turn off the main motor (472).

■Control operation of the control unit (control operation of the rotary sorter unit) Next, the control unit 400 controls the rotary sorter unit 1000.
The operation of the rotary sorter unit 100 will be explained based on the control operation.

Figure 16 (a), (b), (C), (d), (
e) shows a flowchart of an interrupt handling routine for controlling the rotary sorter unit 100, and these are routines that operate as few times as necessary (each one operates once) during one round of the above-mentioned main flow. In this embodiment, the control section 40 of the instant photographic device main body 300
Although the configuration is such that the operation of the rotary sorter unit 100 is controlled through the rotary sorter unit 100, the present invention is not particularly limited to this, and it is of course possible to provide a control means within the rotary sorter unit 100 for control.

As described above, there are two types of positive sheets 201 to be used: a photographic paper type and a transparent paper type for OHP. These two types of positive sheets 201 have different development times (time until peel-apart); the development time for the photographic paper type is about 90 seconds, and the development time for the transparent paper type is about 240 seconds. For example, the photographic paper type negative/positive bonded body discharged by the developing rollers 325a and 325b is shown in FIG.
As shown in a), the bin 10 is moved by the roller pair 107.
6. The rotor 102 with the bin 106 rotates by an angle corresponding to one bin every 7.5 seconds (12,5
degree) in the counterclockwise direction, and at a position 12 bins (270') rotated from the loading position, that is, after 90 seconds of development time, the bin falls due to its own weight to the output tray. It is discharged to 103. On the other hand, in the case of a transparent paper type negative-positive bonded body, it is rotated by an angle equivalent to one bottle (12.5 degrees) every 20 seconds, and rotated by an angle equivalent to 12 pins (i.e., 240 seconds). must be discharged at the end of the period). Therefore, the photographic paper type and the transparent paper type cannot be mixed in the rotary sorter unit 100 because the timing of the intermittent feeding of the rotor 102 is different. Control so that transparent paper types do not mix.

The flowchart of the set detection routine will be described below with reference to FIG. 16(a).

It is determined whether the sensor S5 is ON or not (701), and if it is OFF, that is, it indicates that the positive sheet assembly 200 is not set, so a predetermined set paper warning display on the display panel 506 is turned off (702). Finish the process. On the other hand, if the sensor S5 is ON, it is determined whether the preceding negative/positive bonded body is present in the rotary sorter unit 100 (703), and if it is not present, it is determined whether the positive sheet assembly 200 is a transparent paper type or not (704).
), if it is a transparent paper type, the transparent paper flag is set to "1" (705)L, and if it is not a transparent paper type, the transparent paper flag is set to "0" (706). Furthermore, if there is a preceding negative/positive bonded body in the rotary sorter unit 100, it is determined whether the inserted positive sheet assembly 200 is a transparent paper type (707), and this determination result is compared with the transparent paper flag. If they match, the rotary sorter unit 10
If they do not match, photographic paper and transparent paper will be mixed in the rotating sorter unit (100), so the predetermined set paper warning display will be turned on and the process will end. (708,709°710
).

Next, a rotation control routine for controlling the rotation of the rotary sorter unit 100 will be described with reference to FIG. 16(b).

First, it is determined whether or not the sensor S24 of the negative/positive bonded body is ON (711), and if it is ON, rlJ is set to the discharge sensor F (flag) indicating that the negative/positive bonded body has passed the sensor S24. 712), the process proceeds to step 718. On the other hand, if it is not ONL, it is determined whether it is "1" with reference to the discharge sensor F (713), and if it is not "1", it is shown that it has not passed, so step
If it is rlJ (WI, if the negative/positive conjugate has already passed the position of sensor S24), set the discharge sensor F to "1" and clear the discharge sensor OFF timer, then Start (714, 715L to determine whether or not the preceding negative/positive bonded body is stored in the rotor 112), and if the preceding negative/positive bonded body is not stored, the timing of intermittent feeding is counted. After clearing the intermittent feed timer, start it (
717). Further, if the preceding negative/positive bonded body is stored, the intermittent feed timer is already operating, so the process directly advances to step 718. Next, it is determined whether the transparent paper flag is "1" (71B), and if it is "1" (i.e.,
If the negative/positive bond housed in the rotary sorter unit 100 is a transparent paper type), it is determined whether the intermittent feed timer is longer than 20 seconds (719), and if it is not longer than 20 seconds, the rotation time of the rotor 102 ( Since the intermittent feeding time has not been reached, the process is terminated, and if it is longer than 20 seconds, the rotor 1
Since the rotation time of 02 has been reached, the process advances to step 721. Also, if the transparent paper flag is not "1" (that is, if the negative/positive composite housed in the rotary sorter unit 100 is of photographic paper type), the intermittent feed timer is set to 7.
If it is 7.5 seconds or more, the rotation time of the rotor 102 (intermittent feeding time) has not been reached, so the process is terminated. If it is 7.5 seconds or more, the rotation time of the rotor 102 is Since the rotation time has been reached, the process advances to step 721. If it is determined in steps 719 and 720 that the rotation time has been reached, clear the intermittent feed timer (set it to "0").
), there is no negative/positive bonded body in the bin 106 located in the opening 108, and the negative/positive bonded body is being stored in the rotary sorter unit 100 (when the sensor S24 is ON or the discharge sensor is OFF). If the timer is below Tsec), rotate the rotor 102 (1/16 rotation)
(722, 723, 724° 725). On the other hand, if there is a negative/positive bonded body in the bin 106 located in the opening 108 or if a negative/positive bonded body is being stored in the rotary sorter unit 100, when the rotor 102 is rotated, the negative/positive bonded body is stored in the bin 106 located in the opening 108.・Instead of rotating the rotor 102, add "1" to a predetermined time-up counter (726
), the process ends. Here, whether or not a negative/positive bond exists in the bin 106 located in the opening 108 can be determined by referring to the aforementioned shift register exit bit (see FIG. 1(C)). I can do it.

FIG. 16(C) shows a time-up check routine for executing the rotation of the rotor 102 at an appropriate timing, which was replaced by the value of the time-up counter in step 726 of FIG. 16(b).

Determine whether the time-up counter is “0” (727) L
, "0" indicates that the rotor 102 is rotating smoothly, and the process ends immediately. If the value is not “0”, the rotor 10 is replaced by the value of the time-up counter.
To show that there is a rotation of 2, there is no negative-positive assembly in the bin 106 located in the opening 108, and
If the negative/positive bonded body is not being stored in the rotary sorter unit 100 (when the sensor S24 is ON or the discharge sensor OFF timer is below Tsec), the rotor 102 is rotated (1/16 rotation) and the time-up counter reads "
1” subtract (728°729.730,731.).

On the other hand, if there is a negative/positive bonded body in the bin 106 located in the opening 108, or if the negative/positive bonded body is being stored in the rotary sorter unit 100, the process is immediately terminated.

Next, referring to FIG. 16(d), a discharge check routine for checking whether or not the negative/positive bonded body has been discharged from the bin 106 located in the opening 108 to the discharge tray 103 will be described.

First, it is determined whether a negative/positive bond exists in the bin 106 located in the opening 108 by referring to the output bit of the shift register (see FIG. 1(C)) (732) L
, if a negative/positive bonded body exists, a predetermined negative/positive bonded body removal warning display (details omitted) is turned on (733
) and end the process. If there is no negative/positive bonded body, refer to the time-up counter, and if it is "0", turn off the negative/positive bonded body removal warning display to 0FF (735).
and end the process. On the other hand, the time-up counter is
0'', steps 736, 737゜738.7
39, the rotor 102 is rotated at an appropriate timing with the value of the time-up counter substituted, similarly to the time-up check routine described above.

FIG. 16(e) shows a shift register status check routine, and in this embodiment, the routine checks the rotor 10.
2. Management of storage status (presence or absence) of negative/positive bonded bodies in each bin; rotation prohibition control of the rotary sorter unit 100;
It executes copy prohibition control of the instant photo device main body 300, display control of LED IIO, etc.

It is difficult to determine whether the discharge sensor F is "1" or not (740), "1"
If not, proceed to step 742, and if it is "1", set "1" to the least significant bit of the shift register (741)
. Next, it is determined whether or not to rotate the rotor 102 74.
If the rotation does not occur by 2L, the process advances to step 744, and if the rotation occurs, the shift register is shifted to the left (743). It is determined whether the output bit becomes "1" due to the shift to the left, and if it is not "1", the process proceeds to step 750. On the other hand, if it is "1", it is determined whether the negative/positive bonded body is passing through the sensor S25 and whether a predetermined time (T5ec) has passed since passing through the sensor S25.
6) If the time is less than Tsec during or after passing, the rotation of the rotary sorter unit 100 and the copying operation are prohibited (747).

On the other hand, if Tsec has elapsed since passing, the output bit is set to r□j (748), and the rotation inhibition and copy operation inhibition are canceled (749). Thereafter, the bit information of the shift register is transferred to the LED drive register that drives LEDIIO (850), and the process ends. Here, the LED drive register performs display on the LED IIO based on bit information from the shift register.

In this embodiment, by using the above five routines, for example, the rotor 1.02 may intermittently (
For example, even if the copying process is performed continuously when the rotation speed is 7.5 seconds (for example, every 7.5 seconds), intermittent feeding is performed at appropriate timings that match the development time without causing paper jams. The negative/positive bonded body is discharged onto the discharge tray 103.

Also, as mentioned above, using the time-up counter,
Even if the timing of intermittent feeding elapses while the rotor 102 is prohibited from rotating (for example, when the hexagonal-positive assembly of the discharge tray 103 is being discharged from the opening 108), the rotation request at this time is accumulated. Since the rotor 102 rotates by the number of times indicated by the time-up counter after the rotor 102 becomes rotatable, it is possible to accurately control the time from when the negative/positive bonded body is stored to when it is discharged.

In addition, since the opening 108 is provided below the light-shielding housing 101 so that when the bottle 106 reaches the opening 108, the negative/positive bonded body falls under its own weight and is ejected, the operator forgets to take it out. can be prevented.

In addition, since the light-shielding housing 101 completely blocks external light until the development time ends, a stable image without image fogging etc. can be obtained.

In addition, by providing an LED IIO, it is possible to check from the outside whether negative/positive composites are stored and where they are stored, making it easy to check the approximate time until the end of the development time (time until they are ejected), the number of sheets stored, etc. It is convenient to know.

FIGS. 17(a) and 17(b) and FIG. 18(a), et al. show a second embodiment of the storage device for an instant photographic device according to the present invention. In the first embodiment, as described above, the intermittent feed timing of the rotary sorter unit 100 is changed depending on whether the positive sheet 201 is a photographic paper type or a transparent paper type, so that the development time elapses can be adjusted accordingly. In the second embodiment, the angular ratio from the storage position of the negative/positive bonded body to the opening 108 is clockwise and counterclockwise.
The position of the opening 108 is set to match the development time ratio, and the rotor 102 is configured to be able to rotate in both directions.
The structure is such that the direction of rotation is switched and rotated based on the type of bonded body (photographic paper type or transparent paper type). Thereby, positive sheets 101 having different development times can be carried in by simply switching the rotation direction of the rotor 102 without changing the timing of intermittent feeding, and the same effect as in the first embodiment can be obtained.

Note that even in this method, if a negative/positive bonded body is already stored in the rotary sorter unit 100, the rotation of the rotor 102 is stopped while the next negative/positive bonded body is being discharged from the instant photographic device main body 300. prohibit. Further, if the type of the already stored negative/positive bonded body and the positive sheet assembly 200 to be inserted next are different, the insertion of the positive sheet assembly 200 is prohibited.

Further, in the first embodiment, the opening 108 was provided at the bottom, but by providing the opening 108 at the top as shown in FIGS. It can be incorporated into the machine, thereby reducing the space occupied by the machine.

In the second embodiment, the angle ratio between the clockwise angle and the counterclockwise angle from the storage position of the negative/positive bonded body to the opening 108 matches the development time ratio and is located above. Since the configuration is the same as that of the first embodiment except that the opening 108 is provided, explanation and illustration of the other parts will be omitted.

The flowcharts of the rotation control routine and time check routine of the second embodiment will be described below with reference to FIGS. 18(a) and 18(b).

First, it is determined whether or not the negative/positive bonded body turns on the sensor S24 (751).
The discharge sensor F (flag) indicating that the positive bonded body has passed the sensor S24 is set to "1" (752), and the process proceeds to step 758. On the other hand, if it is not ON, refer to the discharge sensor F to determine whether it is "1" (753), "1".
If not, step 75 to indicate that it has not been passed.
Proceed to step 8, and if it is "1" (that is, if the negative/positive bonded body has already passed the position of sensor S24), set "1" to the discharge sensor F and clear the discharge sensor OFF timer. Then, it is started (754, 755), and it is determined whether the preceding negative/positive bonded body is stored in the rotor 112 (756), and if the preceding negative/positive bonded body is not stored, the intermittent feeding is started (754, 755). After clearing the intermittent feed timer that counts the timing, it is started (757). Further, if the preceding negative/positive bonded body is stored, the intermittent feed timer is already operating, so the process directly advances to step 758. Next, it is determined whether the intermittent feed timer is 20 seconds or more (758), and if it is not 20 seconds or more, the rotation time of the rotor 102 (intermittent feed time) has not been reached, so the process is terminated. Since the rotation time of the rotor 102 has been reached, the intermittent feed timer is cleared (set to "0") (759).

Thereafter, buga is placed in the bottle 106 located at the opening 10th.
There is no positive bonded object, and the negative/positive bonded object is being stored in the rotary sorter unit 100 (sensor S24 is ON).
Or if the discharge sensor OFF timer is below Tsec), it is not possible to judge whether the transparent paper flag is "1" or not.
60,761.762), if it is not “1”, the rotor 10
Rotate 2 clockwise 1716 times (763). "1"
If so, the rotor 102 is rotated 1/16 counterclockwise (764). On the other hand, the bottle 10 located in the opening 108

sec), rotating the rotor 102 will cause the inability to eject the negative/positive composite and paper jams, so instead of rotating the rotor 102, a predetermined time-up counter will be set to "1". is added (765), and the process ends.

FIGS. 18A and 18B show a time-up check routine for executing the rotation of the rotor 102 at an appropriate timing, the value of which was substituted by the value of the time-up counter in step 765 of FIG. 18A.

Determine whether the time-up counter is rQ (766) L
, "0" indicates that the rotor 102 is rotating smoothly, and the process ends immediately. If the value is not “0”, the rotor 10 is replaced by the value of the time-up counter.
2, it is determined whether the rotor 102 can be rotated. Here, the sensor 324 is
If N or the discharge sensor OFF timer is equal to or less than Tsec, rotation is not possible, so the process ends (767.768). On the other hand, if the sensor S24 is not ON and the discharge sensor OFF timer is not less than T sec (if it is rotatable), "1" is subtracted from the time-up counter (769), and whether the transparent paper flag is "1" or not. 770), if it is not r i , rotor 1
Rotate 02 1/16 turn clockwise (771). "1
”, the rotor 102 is rotated 1716 times counterclockwise (772), and the process ends.

However, in the second embodiment, it is necessary for the operator to take out the negative/positive bonded body that has reached the upper opening 108 and has reached the appropriate development time. Therefore, in order to prevent people from forgetting to take it out, it is recommended to use a buzzer or the like to warn them if it has been left unattended for a predetermined period of time.

(Effects of the Invention) As explained above, the storage device for an instant photographic device of the present invention is an instant photographic device that stores a bonded body of a negative film and a positive sheet after the developer has been spread, which is sent out from a peel-apart type instant photographic device. In this storage device, there is provided a rotary storage means in which a plurality of storage parts for storing a bonded body of a negative film and a positive sheet after developer has been spread are arranged in a radial and rotatable manner; Except for the take-out port for taking out the bonded body, the rotary storage means is equipped with a light shielding means to prevent external light from irradiating inside the storage section, so a plurality of bonded bodies can be stored with a simple configuration, and , can completely block light.

In addition, in the above-described configuration, since the rotating storage means transports the bonded object sent out from the instant photographic device to the position of the take-out port in a time period corresponding to the development time of the bonded object, it is difficult to eject or take out the bonded object from the storage device. At the point when
Since the development process is completely completed, there is no need to manage the development time, and convenience can be improved.

In addition, in the above-mentioned configuration, since the outlet is provided at a position where the joined body that has reached the outlet falls from the storage part to the outside due to its own weight and is ejected, no special drive mechanism is required. , it is possible to automatically discharge the zygote with a simple configuration.

Furthermore, in the above-mentioned configuration, display means for displaying whether or not a bonded body is stored in the storage part is provided at each position outside the apparatus corresponding to the plurality of storage parts of the rotary storage means, so that a plurality of sheets can be stored in the storage part. In a dark box type storage device that can store a bonded body and is completely shielded from light, it is possible to easily recognize whether the bonded body is stored and where it is stored.
