Only one opening 166 is formed in each of the holes 152 so that a single relatively large image can be formed on the photosensitive material P. This single image has a configuration in which the image F at the time of four-image exposure is simply enlarged as shown in FIG.
It becomes a portrait image.

As shown in FIG. 7, a motor 184 is attached to the movable table 134 via a bracket 182 at an intermediate portion of the four-image shooting shutter 136 and the one-image shooting shutter 138. A pulley 186 is fixed to the output shaft of the motor 184, and the endless timing belt 18 wound around these pulleys 186 is provided.
By winding 8 and 190 around the four-image shooting shutter 136 and the pulley 170 of the one-image shooting shutter 138, the motor 184 simultaneously operates the four-image shooting shutter 136 and the one-image shooting shutter 138. It can be rotated by the required angle.

Also, as shown in FIG.
The light guide boxes 192 and 194 correspond to the 6- and 1-image shooting shutter 138. The light guide box 192 is divided into four light guide paths 192A corresponding to the four images F of the four-image shooting shutter 136.
And the light guide box 194 has a single light guide path 194A. The light guide path 192A is a cross-shaped exposure section as shown in FIG.
The exposure light is guided so as to expose the image F having 144 and 146 and to prevent overlapping exposure between these four images F except the cross-character exposure portions 144 and 146. .

As shown in FIG. 7, a guide rod 1 is provided between the side plates 130.
A screw shaft 196 is extended in parallel with 32 and penetrates the bracket 134A of the movable table 134. The screw shaft 196 drives the movable base 134 in the left-right direction by the rotation of the motor 198 attached to the side plate 130, so that the four-image shooting shutter 136 or the one-image shooting shutter 138 is selectively made to correspond to the photosensitive material P. It has become.

218B and lower nipping and conveying rollers 220A and 220B are nipped. These rollers are controlled so that the intermediate portion has a small diameter to prevent adhesion of rubber and receives the motor driving force to accurately stop the photosensitive material P at the photographing exposure position.

The upper nip transport rollers 218A and 218B may temporarily rotate in the direction opposite to the transport direction to apply tension to the photosensitive material P in order to improve the flatness of the photosensitive material P during photographing exposure.

On the back surface of the photosensitive material P at the photographing exposure position, a pressing unit 222 that is pressed against the photosensitive material P during photographing exposure is arranged. In this pressing means 222, the upper and lower ends of the pressing plate 224 are the pins 22.
It is supported by a combination of 5 and the long hole 224A so as to be able to come into contact with and separate from the photosensitive material P, and the long hole 224 is pressed against the photosensitive material P by the rotation of the eccentric cam 226. For this reason, the exposed surface of the photosensitive material P has a punched guide plate at the exposed portion.
228 is arranged to support the pressing force of the long hole 224, and the photosensitive material P
It is designed to maintain the flatness of.

(Explanation of Frame Exposure Section) As shown in FIG. 7, the movable table 134 has frame exposure openings 200 and 202 formed below the 4-image shooting shutter 136 and the 1-image shooting shutter 138. Also these frame exposure openings
A lith film 204 is fixed to 200 and 202 in correspondence with the photosensitive material P side. The lith film 204 includes a light-shielding portion 206 corresponding to the exposure range of the four images F excluding the peripheral portion 146 shown in FIG. 9 and a light-shielding portion 208 corresponding to the image area to be printed by the single-image shooting shutter 138. The light-shielding portions 206 and 208 are surrounded by a blank portion 210. Further, as shown in FIG. 6, stroboscopic light emitting means 212 are arranged corresponding to these frame exposure openings 200 and 202.

Therefore, these frame exposure openings 200 and 202 can form a peripheral portion 146 having a sufficiently large exposure amount around the image F as shown in FIGS. 9 (A) and 9 (B). The product size range S of the photosensitive material P (which is cut into this size S if necessary) is smaller than the peripheral portion 146.

If symbols and characters such as the date of photography are attached to a part of the blank portion 210, these symbols and characters can be formed on a part of the image F.

(Explanation of Water Application Section) As shown in FIG. 2, a vertical guide path 230 similar to the vertical guide path 110 is provided below the frame exposure section 30, and the vertical guide path 230 and the water application section 32 are connected to each other. Between the pair of guide plates 23
2, 234 are arranged. The guide plate 234 is divided into an upper guide plate 234A and a lower guide 234B as shown in FIG. 11,
A gap portion 236 is provided between them. These guide plates 232 and 234 can hold only the both ends in the width direction of the image F, like the vertical guide path 110.

The gap portion 236 is provided to absorb the difference in processing speed between the photographing exposure unit 28, the frame exposure unit 30, and the water application unit 32. That is, since the processing speed of the photographing exposure unit 28 and the frame exposure unit 30 is relatively high, and the processing speed of the water application unit 32 is low, the vertical guide path 230 is formed of the same photosensitive material P as the photographing exposure unit 28 and the frame exposure unit 30. When the photosensitive material P is conveyed at the conveying speed, the water application section
When 32 is conveyed at a low speed, the gap portion 236 automatically forms a bent portion 238 in the middle portion of the photosensitive material P with the tip of the photosensitive material P reaching the water application portion 32 as shown in FIG. It is formed to absorb the difference in processing speed.

As shown in FIGS. 12 and 13, the water application part 32 is a lower case 242.
And an upper case 244 are provided which are fitted together to form a sealed condition to reduce water evaporation.

The lower case 242 has a water tray 246 inside and can store water as an image forming solvent. To the water tray 246, the tank 2 as shown in FIG.
The water 250 in 48 is supplied by a pump 252 through a pipe 254. This supplied water 250 is in tank 2
The heater 256 disposed inside the heater 48 maintains a predetermined temperature to improve the image forming efficiency and prevents the water 250 from freezing.

In the water tray 246, a pair of lower rollers 260A and 260B are fixed to the lower support shafts 262 at the entrance and exit of the photosensitive material P, respectively. These lower support shafts 262 are pivotally supported by the lower case 242, and one of the lower support shafts 262 is configured so that the gear 264 fixed to the outside of the lower case 242 is rotated by the driving force of a motor (not shown). ing. Further, endless guide belts 266 are respectively laid between the lower rollers 260A and 260B of the entrance and exit of the photosensitive material P to correspond to both ends of the photosensitive material P in the width direction.

On the other hand, an upper support shaft 276 is rotatably supported by a bracket 270 fixed to the upper case 244, and lower rollers 260A,
The upper rollers 274A and 274B are fixed to correspond to 260B.
On one of the upper support shafts 276, a gear 278 fixed to the shaft end is a lower support shaft.
It meshes with a gear 280 fixed to the end of 262, and is rotated by receiving the rotational force of the lower support shaft 262. An endless guide belt 282 is stretched between these upper rollers 274A and 274B, and one end of the linear portion of the endless guide belt 266 is in close contact with the image F between them.
Both widthwise ends of the can be pinched and conveyed.

In this case, the gap between the upper rollers 274A and 274B is smaller than the lower roller 26.
It is made shorter than between 0A and 260B, and the upper rollers 274A and 274B bend the endless guide belt 266 downward, and the endless guide belt 2
The adhesion between the 82 and the endless guide belt 266 is improved.

The upper case 244 is axially supported by the lower case 242 via a hinge 284 as shown in FIG. 12, and is kept closed by the locking means 286. Therefore, it is possible to prevent unnecessary evaporation of the water 250 at the predetermined temperature in the water tray 246. However, by releasing the locking means 286, the upper case 244 is swung up with respect to the lower case 242 as shown in FIG. 13, and the inside is opened to facilitate the repair work.

Incidentally, the water-applied photosensitive material P sent out between the endless guide belt 266 and the endless guide belt 282 is nipped by the exit nip conveying rollers 290, 292 and reaches the heat developing section 36.

(Description of Image Receiving Material Receiving Section) A plurality of image receiving materials R as shown in FIGS.
Are housed in layers on the lift 300.

The elevating table 300 can be moved up and down by being guided by a plurality of guide rods 304 standing upright in the image receiving material box 302. Also, one end of a cable 306 is fixed to the lifting table 300, and a weight 308 is fixed to the other end of the cable 306. The middle portion of the cable 306 is wrapped around the middle portion of the guide pulley 310 to change the direction. Therefore, when the weight 308 exerts a downward biasing force due to its own weight, the lifting platform 300 can be raised by receiving this upward biasing force.

As a result, the lift table 300 always presses the uppermost image receiving material R against the stopper 312 by the urging force of the weight 308. However, when the number of the image receiving material R decreases, the uppermost image receiving material R is pressed against the stopper 312. If the number of the image receiving materials R decreases, the pressure absorbing effect against the force applied in the thickness direction of the image receiving material R decreases, so that the pressing force applied to the image receiving material R increases. In order to adjust this, the lift table 300 has a tension coil spring 314 between it and the image receiving material box 302, and the weight 308 resists the urging force of the weight 308.
Is urged downward by a biasing force weaker than the biasing force of the weight 308.

The half-moon roller 316 corresponds to the uppermost image receiving material R. The half-moon roller 316 has a timing belt 322 wound around a rotary shaft 318 fixed to the shaft center, the timing belt 322 receiving a driving force of a motor 320. For this reason, in the half-moon roller 316, the notch 316A corresponds to the uppermost image receiving material R in the normal state, but when the motor 320 rotates, the outer peripheral portion of the notch 316A is the uppermost image receiving material R.
Is pushed out in the direction along the paper surface and is fed between the conveying rollers 326 and 328.

These transport rollers 326 and 328 are rotated in opposite directions. That is, the transport roller 326 is the half-moon roller 316.
The uppermost image receiving material R is rotated in the direction of arrow J to be sent out between the guide plates 330 and 332, but the conveying roller 328 is rotated in the opposite direction as indicated by arrow K. The image receiving material R is returned into the image receiving material box 302. Therefore, when two image receiving materials R are carelessly stacked and sent by the half-moon roller 316, only the two image receiving materials R on the upper side are sent between the guide plates 330 and 332, and the lower image receiving material R is transferred. Is configured to be returned into the image receiving material box 302.

The image receiving material R sent from the guide plates 330 and 332 is a heat developing section.
It will be sent to 36.

(Explanation of Heat Developing Section) As shown in FIGS. 18 and 19, the heat developing section 36 has a pair of conveying rollers 350A and 350B at the inlet, a pair of conveying rollers 352A and 352B at the middle, and an outlet at the outlet. Pair of transport rollers 354A, 35
Each of the 4Bs is rotatably supported on the side plate 351 by a bearing 353 to form a horizontal conveyance path. The driving force from the driving source is transmitted to these rollers to open the stores in the directions of arrows L and M. Therefore, the photosensitive material P and the image receiving material R sent out from the water coating section 32 and the image receiving material accommodating section 34 are sent to the heat developing section 36 with the emulsion surface of the photosensitive material P and the image receiving surface of the image receiving material R in close contact with each other.

As shown in FIG. 22, the photosensitive material P is the image receiving material R.
The size and the conveyance timing are determined so that the image receiving material R projects further in the width direction than the photosensitive material P and the image receiving material R reaches the thermal developing section 36 in a state in which the leading end projects in the carrying direction.

Guide plates 356A and 356B are vertically arranged between the respective conveying rollers to guide the light-sensitive material P and the image-receiving material R which are in close contact with each other. These guide plates are arcuate portions 358A, 35 that cover the outer periphery of the respective conveyance rollers on the side opposite to the conveyance path.
8B is integrally formed.

The carrying roller 350A has a hollow portion 360, and the heater 362 is housed in the hollow portion 360. As a result, the heater 362 can heat the conveying roller 350A from the inside and heat the passing photosensitive material P and image receiving material R. A heater 364 is closely attached to the guide plates 356A and 356B on the opposite side of the conveyance path along the outer periphery of the conveyance path and the rollers so that heat can be generated. Therefore, the guide plate 356
The heaters 364 generate heat for A and 356B, so that the photosensitive material P and the image receiving material R in the guide path can be heated.

As a result, the heaters 362 and 364 heat the light-sensitive material P and the image-receiving material R which are in close contact with each other, so that the light-sensitive material P is thermally developed first, and then the developed image can be transferred to the image-receiving material R. It has become.

(Explanation of Peeling and Taking-Out Section) As shown in FIGS. 20 and 21, the peeling and taking-out section 38 is provided with a lower guide plate 390 and an upper guide plate 392 corresponding to both ends of the photosensitive material P fed out. . That is, as shown in FIG. 22, since the photosensitive material P is formed wider than the width dimension of the image receiving material R in advance, both ends of the photosensitive material P projecting from the image receiving material R are above these lower guide plates 390. It is sandwiched and guided by the guide plate 392 and is sent out to the photosensitive material waste box 40.

In order to feed the photosensitive material P into the photosensitive material waste box 40, the endless belts 39 are provided on both sides of the guide path of the photosensitive material P, respectively.
4, 396 are arranged so as to contact the front and back surfaces of the photosensitive material P and send the photosensitive material P into the storage box 56.

In addition, the peeling-out section 38 is provided with endless belts 398 and 400 for sandwiching the front end of the image receiving material R. These endless belts 398 and 400 correspond to both ends in the width direction of the image receiving material R, and hold the front end of the image receiving material R fed from the heat developing section 36 in the horizontal direction to bend and lift it up. It has become. That is, as shown in FIG. 22, the front end portion of the image receiving material R projects in advance and is brought into close contact with the front end portion of the photosensitive material P, and the projection portion of the image receiving material R forms the endless belts 398 and 400. It is designed to be clamped and raised. In this state, the leading end of the photosensitive material P is guided downward by the lower guide plate 390 and the upper guide plate 392, and the image receiving material R lifted upward is the guide plate.
The photosensitive material P guided downward by 390 and 392 is peeled off. A heater 402 is provided so as to correspond to the image receiving surface of the image receiving material R after peeling, and the image receiving material R is dried.

The endless belts 398 and 400 are provided with vertically elongated guide portions 404, and the image receiving material R that is lifted by sandwiching both widthwise end portions of the endless belts 398 and 400 once enters the guide portions 404. From the endless belt 398, 400
When it is sent out from, it is dropped into the take-out box 39 by its own weight.

As shown in FIG. 2, the photographing room 14 of the housing 12
A strobe 18 is provided on a partition 12A that separates the photo production chamber 16 from the photo production chamber 16 and is used for illuminating a person to be photographed 22.

(Operation of Embodiment) In the photosensitive material container 26, the photosensitive material P is sent out from one of the predetermined ones of the photosensitive material magazines 46 or 48 and the cutter 88 is used.
After being cut to a predetermined length by, the sheet is sent to the photographing exposure section 28 and stopped. In this case, the photosensitive material P taken out from the photosensitive material accommodating section 26 and cut by the cutter 88 is conveyed by the conveying rollers 98, 104, and the vertical guide path 110 shown in FIG.
Also, since only the end portion in the width direction is nipped and conveyed by the vertical guide path 230, no dust adheres to the image portion of the photosensitive surface.

If the photosensitive material P whose tip is cut by the cutter 88 is fed backward in the magazine direction by the reverse rotation of the drive rollers 64 and 66 and the light-shielding rollers 94 and 96, and the tip is nipped by the drive rollers 64 and 66, a long time is obtained. Even when not used, pressure fog due to the light shielding rollers 94 and 96 can be prevented.

The person to be photographed 22 enters the photographing room 14 and sits down on the seat 20. The illumination device illuminates the person to be photographed 22 by an operation button (not shown) or coin insertion. At the same time, the motor 198 is driven in the photographing exposure unit 28 so that the four-image photographing shutter 136 or the one-image photographing shutter 1 is selected by the person 22 to be photographed.
38 corresponds to the exposure optical axis O.

When the shutter body 156 is rotated by the rotation of the motor 184 and the opening 158 corresponds to the exposure optical axis O, the photosensitive material P
The image F is exposed upward. In this case, four images F for which the four-image shooting shutter 136 is selected and one enlarged image F for one-image shooting shutter 138 are exposed. In particular, the 4-image shooting shutter 136 is shown in FIG. 8 (A).
As shown in FIG. 9, the openings 174 are formed in the shutter main body 156 unevenly around the center of rotation, that is, in the angle θ, so that four images F are formed as shown in FIG. 9 (A) and FIG. Both are exposed as a vertically long image with the same exposure time.

The shutter body 156 may be rotated in only one direction, or may be reciprocally rotated so as to always return to a fixed position.

Next, the photosensitive material P is sent to the frame exposure section 30. In the frame exposure unit 30, the lith film 204 is in close contact with the photosensitive material P, the light-shielding unit 206 covers the central portion of the image F, and the stroboscopic light emitting unit 212 emits light and the peripheral portion around the image F through the blank portion 210. Expose 146. If the cross-shaped exposure portion 144 and the peripheral portion 146 are made wide, it is possible to cut the obtained photograph into an arbitrary size and form a sufficient white frame portion around the image F.

When the one-image shooting shutter 138 is selected, a large image F is exposed at the center of the one-image shooting shutter 138, and similarly, the periphery of the image F is exposed through the frame exposure opening 202 in the frame exposure unit 30. Frame exposure.

Next, the photosensitive material P sent from the frame exposure section 30 reaches the water application section 32, but its end portion is an endless guide belt of the water application section 32.
When sandwiched between 266 and 288, the transport speed in the water coating section 32 is relatively slow, so the loop bending to the gap section 236 is caused by the speed difference between the trailing end section of the frame exposing section 30 and the relatively fast speed. A portion 238 is formed to absorb this speed difference, and the photosensitive material P is continuously conveyed. .

In the water application section 32, water 250 is applied while passing through the water tray 246 while the photosensitive material P moves at a low speed. This water application part
Within 32, the widthwise ends of the photosensitive material P are endless guide belts 26
Since 6, 282 are sandwiched, unnecessary dust is not attached to the image surface of the photosensitive material P. Further, the water application part 32 is a lower case 242,
Since the upper case 244 is hermetically closed, the evaporation of water in the water tray 246 that is maintained at the predetermined temperature is small.

In the image receiving material accommodating portion 34, a lifting platform 3 that is pushed up by a weight 308.
The image receiving material R is pressed against the stopper 312 by 00, and the image receiving material R of the uppermost layer is rotated by the rotation of the half-moon roller 316.
Is drawn out and sent to the heat developing section 36. Due to the balance between the weight 308 and the tension coil spring 314, the image receiving material R on the elevating table 300 does not have an abnormally large pressing force by the weight 308 even when the number of placed sheets decreases.

The water-applied photosensitive material P is brought into close contact with the image receiving material R fed from the image receiving material accommodating section 34 in the state shown in FIG. 22 and then sent to the heat developing section 36. In the heat developing section 36, the photosensitive material P is rapidly heated to a predetermined temperature by the heaters 362 and 364, so that rapid heat development is performed, and then the developed image is transferred to the image receiving material R. Since the light-sensitive material P to be in close contact has no dust on the light-sensitive surface, there is no transfer failure, and an image can be accurately transferred to the image-receiving material R. Further, since the photosensitive material P is already coated with water, the image forming efficiency is improved.

After the transfer, the photosensitive material P and the image receiving material R are sent to the peeling / extracting section 38 in a close contact state. At the peeling-out section 38, both ends of the photosensitive material P in the width direction are sandwiched and guided by the lower guide plate 390 and the upper guide plate 392, and bent downward. On the other hand, the image receiving material R is pinched by the endless belts 398 and 400 and bent upward, so that the image receiving material R and the photosensitive material P are separated from each other. Photosensitive material P is a photosensitive material waste box 40
The image receiving material R is accommodated in the inside, is sent by the endless belts 398 and 400 and once rises to the guide portion 404, and is then taken out to the take-out box 39 to become a product. This image receiving material R is a heater 40
Since it is heated and dried by 2, the photographed person 22 can immediately take out this.

As an example, after all the photosensitive material P has been pulled out from the photosensitive material magazine 46, the storage box 56 is rotated to the imaginary line state in FIG. 3 to take out the photosensitive material magazine 46 from the storage box 56. The photosensitive material P is supplied from the material magazine 48, and the storage box 56 of the photosensitive material P that has been pulled out from the photosensitive material magazine 48 and reaches to the front of the cutter 88 is in the state of the solid line in FIG. It will not be inadvertently exposed by exchanging. The same applies when the photosensitive material magazine 48 is replaced.

〔The invention's effect〕

As described above, according to the present invention, the widthwise end portions of the photosensitive material are nipped and fed from the accommodating portion to the contact portion, so that dust does not adhere to the central portion of the photosensitive material and the quality of the developed human image is impaired. It has an excellent effect that it can be transferred to an image receiving material without any treatment.
