BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film storage sheet folding apparatus used in an automatic print photograph bagging system.

[0002]

2. Description of the Related Art When a DP reception shop accepts the simultaneous printing of a photographed photo film, it fills in a predetermined item on a DP bag, puts a patrone in the DP bag, and hands it to a large-scale development laboratory. At this large-scale photo lab, the cartridge is taken out from the DP bag, and then the exposed photographic film is taken out from the cartridge. These photographic films are spliced together to form a long film. This long film is developed by a film processor, and then a film inspection by a skilled operator is performed. In this film test, a notch is formed on a frame to be printed, and an exposure correction amount for obtaining an appropriate printed photograph is determined.

Next, the long film is set in an automatic photo printer. The notched frame is printed and exposed on a paper (photographic printing paper) in consideration of the exposure correction amount designated at the film certification. The exposed paper is developed by a paper processor, and then the print inspection is performed with the paper being long. In this print test, re-printing prints that give good results by performing re-printing with different exposures have re-burning marks consisting of, for example, one diagonal line, and uncorrectable unnecessary images such as shooting failures. On the print photograph, an unnecessary mark composed of, for example, two diagonal lines is written on the image with a felt pen or the like.

The roll paper, which has been subjected to the print verification, is loaded into a cutter / sorter, and is cut into each frame here, and is also grouped into one for each case. In this cutter / sorter, a reprint mark or unnecessary mark is detected by a sensor, and based on this mark, one print photograph is sorted into a pass print photograph, a reprint print photograph, and an unnecessary print photograph. The unnecessary print photographs are put in a waste box, and the pass print photographs and the reprint print photographs are discharged to two trays that are inclined. In addition, depending on the width of the paper set in the photo printer, 82.5 × 1 is included in one print photograph.
Besides the E size of 17 mm and the L size of 89 × 127 mm, there is a panoramic size having a length twice as large as these sizes.

On the other hand, the long film which has undergone the printing process is cut into a predetermined number of frames in one photographic film,
The obtained film piece is inserted into the film storage sheet. The operator manually takes out the pass print photograph and the reprint print photograph discharged to each tray and superimposes them. Next, collate the printed photo into one and the photo film in the film storage sheet. If they match, fold the film storage sheet by hand and put it in a print bag together with the print photo. insert. At this time, advertisement leaflets that print various print services are also put in the print bag together. After inserting this print bag into the original DP bag, only the print photos that have passed are sent to the shipping process. Those containing the reprint print photograph are sent to the reprint print step.

[0006]

In the printing system currently in operation, the sorting of print photographs is automated, but the work thereafter is performed manually. For this reason, it takes a lot of manpower to insert a print photograph or a leaflet into a print bag.

Further, an automatic bagging system for printed photographs is disclosed in Japanese Patent Publication Nos. 56-768, 56-35862, 4-70832, and 4-76542.
It is described in Japanese Patent Publication No. However, none of the publications describes a device for folding a film storage sheet.

An object of the present invention is to provide a film storage sheet folding device capable of automatically folding one film storage sheet.

[0009]

In order to achieve the above object, according to the invention of claim 1, both ends of the film storage sheet are sandwiched and rotated, and one film storage sheet is wound flat. Clamping means for folding in the opened state, and opening / closing means for moving the clamping means in the vertical direction of the film storage sheet to set the clamped state for clamping the film storage sheet and the unclamped state for releasing the clamping. The moving means is provided for moving the clamp means in the width direction of the film storage sheet and setting it at the forward position where it enters the transport path and the retracted position where it retracts from the transport path.

The clamping means clamps both sides of the leading edge of the film storage sheet and then rotates to fold the film storage sheet so as to wind it. Next, the clamp means is displaced from the clamped state to the unclamped state, and moves to the retracted position in this state. In this way, the film storage sheet can be easily folded simply by rotating the clamp means while sandwiching both sides of the film storage sheet.

According to the second aspect of the present invention, the clamp means is composed of a pair of clampers arranged to face each other.
When the film storage sheet is inserted into the clampers, each clamper is set to a fully open state in which it is opened further than the unclamped state. Since each clamper stands by in the fully opened state, the film storage sheet can be inserted easily and securely.

According to the third aspect of the invention, when each clamper is set in the unclamped state, it is opened slightly so that it can be pulled out from the rolled film storage sheet, and the clamped state remains. Move each clamper to the retracted position, set each clamper in the fully opened state at this retracted position, then move to the advance position, and set each clamper in the clamped state after the film storage sheet is inserted at this advance position. It was done like this.

In a fourth aspect of the present invention, a pair of conveying rollers is arranged on the inlet side of one set of clampers, and each clamper is rotated in a state where the rotation of the pair of conveying rollers is stopped. One film storage sheet is cut from the perforation.

In the invention described in claim 5, when each clamper moves to the unclamped state after folding one film storage sheet, it enters between them,
Then, after each of the clampers has moved to the retreat position, there is provided a delivery means for sandwiching and delivering one film storage sheet from above and below.

In a sixth aspect of the present invention, a pair of conveyor belts are used, and these conveyor belts are in parallel with each other so as to sandwich the film storage sheet, and do not disturb the folding of the film storage sheet. In addition, it is adapted to move between the V-shaped open position.

According to the invention described in claim 7, each clamper is composed of two sandwiching plates, and the sandwiching plates are reduced in width and thickness toward the tip, whereby each sandwiching plate is wound. It is designed to make it easy to get out of the film storage sheet.

In the invention described in claim 8, one motor, a first gear train for transmitting the rotation of the motor to the opening / closing means, and the rotation of the motor are transmitted to each clamper through the one-way clutch. And a second gear train for performing the operation. When the motor rotates in the first direction, each clamper opens and closes, and when the motor rotates in the second direction, each clamper simultaneously rotates. Since the clamp is opened / closed and rotated by one motor, the structure is simplified.

According to the invention described in claim 9, a part of the first gear train and the second gear train and a pair of movable plates for holding each clamper are provided, and these movable plates are guide rods. It is swingably and slidably supported by. When jamming occurs during folding of the film storage sheet, the movable frame is disengaged from the fixed frame by operating the locking means. When the movable frame is swung with the guide rod as a fulcrum, the clamper escapes, so that the folding space of the film storage sheet is exposed. When the movable frame is swung, the gear lock means locks the gear attached to the movable frame so that the gear does not move. As a result, the rotational position of the clamper does not change during the jamming removal work.

According to the tenth aspect of the present invention, a flexible sheet for guiding the film storage sheet is arranged at the entrance side of the pair of clampers, and the flexible sheet is stored in the folded film storage sheet during folding. To prevent the film piece from breaking.

According to the eleventh aspect of the present invention, the film storage sheet for one case wound around the clamper is pressed down from above and below so as not to be loosened, and a plurality of film storage sheets swings as the clamper rotates. A holding plate is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 is a schematic view showing an automatic bagging system for printed photographs using the apparatus for folding a film storage sheet according to the present invention. As is well known, the paper cutter 10 includes a roll paper 11 and a certified paper 11a.
Pull out and convey to the cutting position. During this conveyance, the cut mark sensor detects a cut mark formed of a small hole formed in the side edge portion of the paper 11a.
The cutter is operated based on the detection signal of the cut mark to cut the paper 11a to obtain one print photograph 1
Cut into two. Further, the paper cutter 10 is provided with a sort mark sensor, detects the sort mark indicating the division of each case, and temporarily suspends the cutting operation based on this to sort each print photograph 12 for each case.

The finished state of each print photograph of the paper 11a is verified in advance in the print verification process. In this print test, the pass print photograph with a good finish remains as it is, but if the exposure amount is corrected and the finish is good, for example, the re-baking mark 13 consisting of one diagonal line is an image of the print photograph. It is written on the surface. Further, if the exposure amount is not corrected, the finish is not good, for example, in a defocused print photograph, an unnecessary mark 14 composed of two diagonal lines is written.

The print photo sorting device 17 detects the re-baking mark 13 or the unnecessary mark 14, and based on this, operates each branch guide arranged in the middle of the transport path to change the transport destination of the print photo 12. Thus, the reprint print photograph 12a, the pass print photograph 12b, and the unnecessary print photograph 12c are sorted. The reprinted and passed print photographs 12a and 12b are separately collected.
After sorting one print photo, the re-baked integrated print photo 18a and the accepted integrated print photo 18b are sent to the elevator 19, and the elevator 19 superimposes one integrated print photo 18a, 18b. The unnecessary print photograph 12c is sent to the waste box by the branch guide.

When the electromagnetic clutch 153 is turned on and the motor 132 is rotated in reverse, the dancer portion 85a is set to the highest position. At this time, since the round belt 130 hits the stopper 157 attached to the spring plate, the free rollers 88 and 89 are pushed and come into contact with the drive rollers 86 and 87, so that the film storage sheet 26a can be conveyed. Further, since the one-way clutch 151 prevents the shaft 91 from rotating in the clockwise direction, the dancer portion 85a is held at the highest position.

When forming the loop of the film storage sheet 26a, the electromagnetic clutch 153 is turned off. When the electromagnetic clutch 153 is turned off, the one-way clutch 151 is released, so that the film storage sheet 26
According to the loop amount of a, the dancer portion 85a swings clockwise about the shaft 91 as a fulcrum toward the lowest position.
Further, as the loop amount decreases, the dancer portion 85a swings counterclockwise toward the highest position. Dancer section 8
Since one end of the spring 158 is fixed to the electromagnetic clutch 153 so as to cancel the moment due to gravity of 5a, the dancer portion 85a can be moved up and down with a light tension.

5 to 11 show a folding mechanism. The pair of clampers 98a and 98b are arranged so as to face each other on both sides of the conveyance path of the film storage sheet 26a, and sandwich and rotate both sides of the leading end of the film storage sheet 26a. These clampers 98a, 98b
Is the same except that the orientation is different, so one clamper 9

As shown in FIG. 7, the clamper 98a has two
It is provided with individual clamper blocks 160a and 161a. These clamper blocks 160a and 161a are
The holding plates 99a and 100a are integrally formed, and a pair of shafts 16 are installed on a U-shaped clamper frame 162a.
It is slidably attached to 3a and 164a. Further, the clamper blocks 160a and 161a are provided with springs 165a and 165a so that the pair of holding plates 99a and 100a hold the film storage sheet 26a.
It is energized at 166a. These clamper blocks 160a and 161a include a pair of rollers 167a and 168.
When a is horizontal as shown in FIG. 7, it approaches, and when a is vertical, it separates.

Each of the sandwiching plates 99a and 100a, after winding one film storage sheet 26a around it, moves to the retracted position with the clamp release state, which is slightly opened, and then comes out of the film storage sheet 26a. In order to facilitate this extraction, each holding plate 99a, 100a
As shown in FIG. 5, the shape of the is a trapezoid in which the width of the tip is narrow when viewed from the top. Also, as shown in FIG.
It is tapered so that the thickness becomes thinner toward the tip.

As shown in FIG. 9, a pair of rollers 167 are provided.
a and 168a are attached to the holder 169a. The holder 169a is fixed to the tip of a rotary shaft 170a that locks the large gear 114a. Therefore, when the large gear 114a rotates, the holder 169a rotates via the rotating shaft 170a, so that the roller 167 is rotated.
a, 168a, clamper blocks 160a, 16a
1a is pushed in the separating direction, and a pair of holding plates 99a, 100
Moves from the unclamped state to the fully open state.

When the clamper frame 162a rotates, the pair of holding plates 99a and 100a rotate around the rotation shaft 170a, and the film storage sheet 26a is folded.
A shaft cylinder 171a is fixed to the clamper frame 162a in order to rotate the clamper frame 162a. The shaft cylinder 171a is fitted to the rotary shaft 170a via a bearing 172a so that it can rotate relative to the rotary shaft 170a, and the large gear 115a is provided at the rear end.
Is stuck. Further, the shaft cylinder 171a is held by a holder 174a via a bearing 173a, and this holder 174a is fixed to a movable frame 175a. Therefore, the movable frame 175a includes the clamper 98a, the large gears 114a and 115a, and the gear 110.
a and 112a are attached and unitized.

As shown in FIGS. 5 and 10, the pair of movable frames 175a and 175b is slidably fitted to the guide rod 178 and is attached to the roller 179 mounted below.
a and 179b are fitted in the guide grooves 180a and 180b. Further, racks 181 a and 181 b are attached to the movable frames 175 a and 175 b, and these are meshed with both sides of the pinion 182. When the pinion 182 is rotated by the motor 183, the pair of movable frames 175a and 175b move in opposite directions, so that the clampers 98a and 98b are selectively set to the forward movement position and the retreat position. When the movable frames 175a and 175b are further pulled out from the retracted position, the rollers 179a and 179b are removed.
Is disengaged from the guide grooves 180a and 180b, the movable frames 175a and 175b can be swung with the guide rod 178 as a fulcrum.

Inside the movable frames 175a, 175b, as shown in FIG.
84b are arranged, and clampers 98a,
Openings 185a and 185b are formed for the 98b to enter and exit. Therefore, the movable frame 175a,
When 175b is swung around the guide rod 178, these openings 185a and 185b are exposed, so that when jamming of the film storage sheet 26a occurs, the 175b is removed from the folding space existing between the pair of clampers 98a and 98b. The jammed film storage sheet 26a can be taken out.

As shown in FIG. 11, an optical sensor including a light projecting section 188 and a light receiving section 189 is arranged between the pinch rollers 93 and 94. When the optical sensor detects the leading edge of the film storage sheet 26a, the conveyance roller 9
2 is stopped, the electromagnetic clutch 153 of the buffer device 85 is turned off, and the film storage sheet 26
It becomes possible to form a loop of a.

In the optical sensor including the light projecting section 190 and the light receiving section 191, the tip of the film storage sheet 26a is
It is detected that the clamp plates 98a and 100a of the clamper 98a and the clamp plates 99b and 100b of the clamper 98b are properly inserted. With the signal from this optical sensor, the motor 104 is rotated and the folding sequence of the film storage sheet 26a is started.

On the inlet side of the clampers 98a and 98b,
A lower guide 194 whose front end is curved downward and an upper guide 195 obliquely arranged are provided. Since the film storage sheet 26a is curved along the lower guide 194, the lower guide 194 and the clamper 98a,
If the gap between the film storage sheet 26a and the sheet 98b is narrow, the film storage sheet 26a may be bent too much, and the stored film piece may be bent. Therefore, the lower guide 1
There is another problem that it is difficult to insert the leading end of the film storage sheet 26a into the clampers 98a and 98b because the gap between the clamp 94 and the clampers 98a and 98b is large. In this embodiment, a mylar 196, which is a plastic sheet having elasticity, is mounted on the lower guide 194. By installing this mylar,
The film piece is prevented from bending and the clamper 9
It facilitates insertion into 8a and 98b.

Next, the feeding mechanism 119 for the folded film storage sheet 24 will be described with reference to FIG. Rotation shafts 201 and 202 are attached to the bases and tips of the pair of arms 200a and 200b. The drive rollers 203a and 203b are fixed to the rotary shaft 201, and the free roller 204 is fixed to the rotary shaft 202.
The shafts a and 204b are fixed. 2 for these rollers
The upper delivery belts 117a and 117b of the book are hung. A rotary shaft 205 is attached in the middle of the pair of arms 200a and 200b, and tension rollers 206a and 206b for eliminating looseness of the upper feeding belts 117a and 117b are fixed to the rotary shaft 205. Therefore, when the rotary shaft 201 rotates in the direction of the arrow, the drive rollers 203a and 203b rotate, so that the upper delivery belts 117a and 117b rotate.

A pulley 209 is provided at the base of the arm 200a.
Are fixed and rotated by the belt 210.
When the pulley 209 rotates, the pair of arms 200
Since a and 200b swing around the rotary shaft 201 as a fulcrum, the upper delivery belts 117a and 117b move in and out of the conveyance path of the film storage sheet 26a. The lower delivery belts 118a and 118b are also the upper delivery belts 1
Since the structure is the same as that of 17a and 117b, the portions necessary for explanation are given the reference numerals and the explanation thereof is omitted.

The delivery mechanism 119 includes one motor 2
The arm 17 swings and the belt rotates. The rotation of the motor 217 is transmitted to the pulleys 219 and 220 by the belt 218. A one-way clutch 221 is arranged between the pulley 219 and the rotary shaft 212. A gear 222 is fixed to the rotary shaft 212 and meshes with a gear 223 which is fixed to the rotary shaft 201. Therefore, the motor 21
Only when 7 rotates in the clockwise direction indicated by the solid line, the rotation of the pulley 219 is transmitted to the rotation shafts 212 and 201, whereby the lower delivery belts 118a and 118b and the upper delivery belts 117a and 117b have the same speed. And rotate together.

A one-way clutch 226 is arranged between the pulley 220 and the rotary shaft 227. The one-way clutch 226 causes the rotating shaft 227 to rotate in the dotted line direction only when the motor 217 rotates counterclockwise. A gear 229 meshing with the cam gear 228 is fixed to the rotary shaft 227. Cam gear 2
A leaf-shaped cam 230 is fixed to the cam 28, and a fork-shaped swing lever 23 is attached to the cam 230.

As described above, the film storage sheet 26
When jamming occurs at the time of folding a, the movable frames 175a and 175b are swung with the guide rod 178 as a fulcrum. At this time, the gears 110 and 112 are replaced by the gear 1
The gears 110 and 112 are mistakenly turned during the jamming process, so that the rotational position of the clamper 98 changes.
With the rotational position of the clamp 98 deviated, the movable frames 175a and 175b are returned to their original positions, and the gears 110 and 11 are rotated.
When 2 is engaged with the gears 109 and 111, the film storage sheet 26a cannot be inserted between the holding plates 99 and 100.

Therefore, the gears 110 and 112 are replaced by the gear 10.
A gear lock mechanism is provided to prevent the large gears 114 and 115 from rotating when disengaged from the gears 9 and 111.
As shown in FIGS. 13 and 14, a bush 250 is fixed to a movable frame 175a, and a shaft 251 is rotatably and slidably held on the bush 250. A knob 252 is attached to one end of the shaft 251, and a T-shaped engaging piece 253 is fixed to the tip. This engagement piece 2
53 is a block 25 fixed to the movable frame 175a.
Engage 4 The block 254 includes an engaging piece 253.
A hole 254a having substantially the same shape as that of is formed, and when the knob 252 is rotated 90 degrees, the engaging piece 253 is fitted in the hole 254a. In this state, the spring 255
As a result, the shaft 251 slides to the right. Note that reference numeral 25
6 is for controlling the sliding range of the shaft 251.

A washer 257 biased by a spring 255 is attached to the inside of the knob 252. The tip of an interlocking pin 259 fixed to the lock arm 258 is in contact with the washer 257. The lock arm 258, which is substantially L-shaped, is swingably held by a shaft 260 in the middle of the lock arm 258, and has a brake shoe 26 at its tip.
1 is attached. A spring 262 is hooked on the lock arm 258 and the holder 174a. Before swinging the movable frame 175a, turn the knob 2
When 52 is rotated 90 degrees, the shaft 251 slides, so that the lock arm 258 rotates clockwise. Brake shoe 2
61 is a large gear 114a,
These large gears 1 are pressed against the outer periphery of 115
14a and 115 are locked so as not to rotate.

Next, the operation of the folding device for the film storage sheet will be described with reference to FIGS. 15 and 16.
Roll the film storage sheet 26a
The supply shaft 49 is loaded. This film storage sheet 26a
, A plurality of pockets are formed at a constant pitch, and a film piece obtained by dividing 50 to 100 photo films for each predetermined number of frames is inserted in each pocket.

The film storage sheet 26a pulled out from the roll 26 passes through the tension roller 50, the pull-out roller pair 51, the perforation detection device 52, and the transport roller pair 61, and is sandwiched on both sides by the transport belts 66 and 67. In this state, it passes between the schaukasten 65 and the transparent glass 64. Next, it reaches the perforation detection device 78, and the perforation provided at the boundary for one case is detected. The length of one film storage sheet 26a is measured by measuring the rotation amount of the transport roller pair 77, for example, during the period from the time when this perforation is detected until the time when the next perforation is detected. Further, since the length of one pocket is known, the number of pockets (number of steps) of one film storage sheet can be obtained.

When the perforations are detected, the transport of the film storage sheet 26a is temporarily stopped, and the two glass plates 79 are brought close to each other between them to sandwich the film storage sheet 26a and make it flat. One set of barcode reader 25a
Reads the barcode of the ID number printed in the first pocket of the film storage sheet 26a for one case. After reading the barcode, the film storage sheet 26
The conveyance of a is started, and is conveyed to the buffer device 85 via the conveyance rollers 83 and 84.

When the power is turned on, the buffer device 85
Prepares for automatic loading of the film storage sheet 26a. That is, the motor 132 shown in FIG. 3 rotates counterclockwise, and this rotation causes the one-way clutch 13 to rotate.
5, pulley 136, belt 138, pulley 140, ON
It is transmitted to the shaft 91 via the electromagnetic clutch 153 in the state. When the shaft 91 rotates counterclockwise, the pair of arms 90a and 90b swing counterclockwise, so that the dancer portion 85a rises toward the highest position.

The shading sector 154 rotates as the dancer portion 85a rises. Then, when the edge 154a of the light shielding sector 154 is detected by the photo interrupter 155, the rotation of the motor 132 is stopped. At this time, the dancer portion 85a is set to the highest position shown by the solid line in FIGS. In this highest position, the stoppers 157 push the round belt 130, so that the free rollers 88 and 89 come into contact with the drive rollers 86 and 87.

After the dancer portion 85a is set to the highest position, the motor 132 rotates clockwise. The rotation of the motor 132 is, as shown by the arrow in FIG. 3, a pulley 134, a belt 137, a pulley 139, a belt 141, and
It is transmitted to the rotary shaft 125 of the drive roller 86 via the pulley 142 and the belt 143. Further, the rotation of the pulley 144 is performed by the drive roller 8 via the belt 145 and the pulley 146.
7 is transmitted to the rotary shaft 126. As a result, the drive rollers 86 and 87 rotate together with the free rollers 88 and 89.

Dancer section 85 set to the highest position
When the film storage sheet 26a enters the sheet a, it is nipped between the drive rollers 86 and 87 and the free rollers 88 and 89 and conveyed. The film storage sheet 26a that has passed through the dancer portion 85a is sent to the transport roller 92 and is held between the transport roller 92 and the pinch roller 93. Then, when the leading edge of the film storage sheet 26a is detected by the optical sensor including the light projecting unit 188 and the light receiving unit 189 shown in FIG. 1, the rotation of the transport roller 92 is stopped.

At the same time as the rotation of the conveying roller 92 is stopped, FIG.
The electromagnetic clutch 153 shown in is turned off. When the electromagnetic clutch 153 is turned off, the gears 150, 152,
Since the reverse rotation prevention mechanism by the one-way clutch 151 is released, the dancer portion 85a tries to lower toward the lowest position shown by the chain double-dashed line in FIG. Here, since the spring 158 is provided, a slight difference between the rotational moment of the dancer portion 85a and the tensile force of the spring 158 acts on the dancer portion 85a.

Even after the rotation of the transport roller 92 is stopped, the transport rollers 83 and 84 and the drive rollers 86 and 87 are rotated to feed the film storage sheet 26a. Accordingly, the dancer portion 85a swings toward the lowest position and the transport roller 8
A loop of the film storage sheet 26a is formed between 4, 92. During formation of this loop, the free rollers 88, 89
Is separated from the stopper 157, so that the free rollers 88 and 89 are separated from the drive rollers 86 and 87 by springs and are suspended by the film storage sheet 26a, as shown by the chain double-dashed line in FIG. In this state, the drive rollers 86 and 87 are idly rotating. The idle rotation of the drive rollers 86 and 87 may be stopped.

When the dancer section 85a reaches the lowest position, the photo interrupter 156 detects the edge 154b of the light shielding sector 154. This photo interrupter 156
Signal, the folding sequence of the folding mechanism 97 is started. After that, the dancer unit 85a moves up and down between the lowest position and the highest position according to the difference between the processing speed of the folding mechanism 97 and the reading processing speed of the barcode reader 25a, and the photo interrupter 156. The folding sequence is started each time the signal is generated.

At the start of the folding sequence, the clampers 98a and 98b arranged on both sides of the conveying path are set to the forward position, and the pair of holding plates 99a and 100a are set.
And the pair of holding plates 99b, 100b are in a fully opened state in which they are wide open. Further, in the delivery mechanism 119, the upper delivery belt 117 and the lower delivery belt 118 are in the transport path.

When the folding sequence is started, the transport roller 92 first rotates to transport the film storage sheet 26a toward the folding mechanism 97. The film storage sheet 26a passes through the mylar 196 shown in FIG. 11, and then the upper delivery belt 117 and the lower delivery belt 118.
Is nipped between. These delivery belts 117,
While the film storage sheet 26a is conveyed at 118,
Both sides thereof enter between the pair of holding plates 99a and 100a and the pair of holding plates 99b and 100b.

When the front end of the film storage sheet 26a is detected by the optical sensor including the light projecting section 190 and the light receiving section 191, the motor 104 shown in FIG. 1 rotates in the clockwise direction indicated by the solid line by a predetermined amount. The rotation of the motor 104 is performed by the gear 1
Large gear 1 through 05, 106, 107, 109, 110
14 and the large gear 114 rotates 90 degrees. At this time, since the control gear 113 is braked, the large gear 115 does not rotate.

As shown in FIGS. 7 and 9, when the large gear 114a rotates, for example, the two rollers 167a and 168 are rotated.
a becomes a horizontal state. In this case, the spring 165
a, 166a, clamper blocks 160a, 1
Since the 61a moves in the direction of approaching each other, the pair of holding plates 99a and 100a hold the film storage sheet 26a. Similarly, since the clamper 98b is also in the clamped state, the clamper 9 is provided on both sides of the film storage sheet 26a.
It is sandwiched between 8a and 98b.

After the clampers 98a and 98b are set in the clamped state, the motor 217 shown in FIG. 12 rotates a predetermined amount in the counterclockwise direction indicated by the dotted line. This motor 21
The rotation of the gear 7 is via the belt 218, the pulley 220, the one-way clutch 226, the shaft 227, and the gear 229.
28, and the gear 228 rotates by 90 degrees. Here, the pulley 219 also rotates, but this pulley 2
Since the one-way clutch 221 is arranged between the shaft 19 and the shaft 212, the rotation of the pulley 219 can be prevented by rotating the rotary shaft 2.
Not transmitted to 12. Therefore, the delivery belt 11
7,118 never reverses.

When the gear 228 rotates 90 degrees, the cam 230 causes the rocking lever 231 to rock clockwise against the spring 232. The movement of the swing lever 231 is caused by the gear 233, the gear 234, the gear 235, and the rotary shaft 2.
It is transmitted to the pulley 237 via 36. This pulley 2
The rotation of 37 is transmitted to the belt 214 and the pulley 213, and the arm 211a to which the pulley 213 is fixed swings counterclockwise around the rotation shaft 212. Also,
The rotation of the gear 235 is performed by rotating the gear 238, the pulley 239, the belt 240, the pulley 241, the rotating shaft 242, and the pulley 24.
3, transmitted to the pulley 209 via the belt 210.
Since the pulley 209 is fixed to the arm 200a, the arm 200a swings clockwise around the rotating shaft 201. As a result, the upper delivery belt 117
a, 117b and lower delivery belts 118a, 118b
Retract from the transport path.

After the delivery mechanism 119 is retracted from the transport path, the motor 104 rotates in the counterclockwise direction shown by the dotted line in FIG. This rotation is performed by the gear 105, the gear 106, and the gear 1.
It is transmitted to the large gear 115 via 08, the gear 111, and the gear 112. For example, when the large gear 115a rotates, the clamper blocks 160a, 16a are
The clamper frame 162a holding 1a rotates.
When the large gear 115a rotates, the large gear 114a is also rotated in the same direction by the motor 104 at the same speed as the large gear 115a. As a result, during rotation of the clamper 98a, the straight line connecting the rollers 167a and 168a becomes
The clampers 98a and 98b are held in the clamped state because they remain vertical to the 3a and 164a.

In this way, the pair of clampers 98a,
98b rotates at the same time, and the left and right holding plates 99a, 100a
Then, as shown in FIG. 16, the film storage sheet 26a is wound around the holding plates 99b and 100b so as to be folded. During this winding, the film storage sheet 26a
Is pressed by swingable pressing plates 101 and 102 so as not to loosen.

Since the length of one film storage sheet 26a is known, when the transport roller 92 sends the film storage sheet 26a by this length, the transport roller 92 stops. At this time, the perforation line is the pinch roller 94.
It's a little out of. Since the pair of clampers 98a and 98b rotate even after the transport roller 92 stops, the film storage sheet 26a is torn from the perforations.

When the clampers 98a and 98b are rotated,
The control gear 113 is also rotating together, and this control gear 1
The amount of rotation of 13 is measured by a measuring device (not shown).
Then, the control gear 1 is provided in an amount corresponding to the number of pockets (steps) determined by the length of one film storage sheet 26a.
When 13 rotates, the rotation of the motor 104 stops. For example, if the number of pockets is 5 or less, the clampers 98a, 9a
8b makes one rotation, and 6 or more makes two rotations. The maximum number of photo films currently on the market is 36, which is divided into 7 film pieces.
8a and 98b do not rotate more than twice. In the embodiment shown in FIG. 16, since the number of pockets is 5, the clampers 98a and 98b rotate once, and when the last pocket is wound, the clampers are cut from the perforations.

When the winding of the winding mechanism 97 is completed, the motor 217 rotates again in the direction indicated by the dotted line, as described above. As a result, the cam 230, which is in the horizontal state, rotates 90 degrees and is in the vertical state. The cam 230 causes the swing lever 231 to rotate in the clockwise direction against the spring 232, so that the arms 200a and 211a swing in the approaching direction. As a result, the upper delivery belt 1
17a, 117b and lower delivery belts 118a, 11
8 and 8 enter the conveyance path, and sandwich one folded film storage sheet 24.

Next, since the motor 104 rotates in the clockwise direction, the shaft 170a, for example, rotates via the gear train as described above. When the shaft 170a rotates, for example, 45 degrees, the clamper blocks 160a and 161a are slightly separated against the springs 165a and 166a. As a result, the pair of clampers 98a and 98b are set in the unclamped state. The delivery belts 117 and 118 may enter the conveyance path after the clamp is released.

Next, since the motor 183 shown in FIG. 5 rotates, the movable frames 175a and 175b are moved to the guide rod 178 by the pinion 182 and the racks 181a and 181b.
Move away from each other. By the movement of the movable frames 175a and 175b, the pair of clampers 9
8a and 98b move to the retreat position where they are pulled out from the folded film storage sheet 24.

After the pair of clampers 98a and 98b are retracted, the upper delivery belts 117a and 117a of the delivery mechanism 119 are retracted.
17b and the lower delivery belts 118a and 118 rotate, so that the folded film storage sheet 24 is fixed to the frame plate 121.
To discharge. After this ejection, the motor 104 of the folding mechanism 97 rotates in the direction indicated by the solid line. The rotation of the motor causes the large gears 114a and 114b to rotate by a predetermined amount, so that the straight line connecting the pair of rollers 168a and 168b shown in FIG. 7 is in a vertical state in which it is parallel to the shafts 163a and 164a. A pair of clamper blocks 160a and 161a
Is further separated against the springs 165a and 166a, so that the clampers 98a and 98b are fully opened.

After the clampers 98a and 98b are fully opened, the motor 183 shown in FIG. 5 rotates in the reverse direction, so that the pair of movable frames 175a and 175b advance and the clamper 9 moves.

Next, if the knob 252 is grasped by hand and pulled to the front, the movable frames 175a and 175b move beyond the retracted position, and the clampers 98a and 98b are fixed as shown by the two-dot chain line in FIG. The frame 184a, 184b exits through the opening 185a, 185b. Then, when the rollers 179a, 179b come out of the grooves 180a, 180b, the movable frames 175a, 175b are moved to the guide rods 17a.
While swinging counterclockwise in FIG. 13 with the fulcrum 8 as a fulcrum, the gears 110 and 112 disengage from the gears 109 and 111.

When the movable frames 175a and 175b swing, the openings 185 of the fixed frames 184a and 184b.
Since a and 185b are exposed, the jammed film storage sheet 26a can be taken out by inserting the hand into the folding space. When the movable frames 175a and 175b are returned to their original positions after the jamming is resolved, the gear 11
The gears 0 and 112 mesh with the gears 109 and 111. Next, when the movable frames 175a and 175b are returned to the retracted positions and the knob 252 is pushed in and rotated 90 degrees, the engagement piece 253 engages with the hole 254a. When the knob 252 is pushed, the lock arm 258 is rotated and the large gear 114,
Unlock 115. With this gear lock mechanism, the large gears 114 and 115 do not rotate excessively,
There is no deviation between the rotational positions of the clampers 98a and 98b and the rotational position of the control gear 113.

As described above, according to the present invention,
The film storage sheet can be moved in and out of the transport path, and the film storage sheet is provided with a clamping means that displaces the clamped state in which both sides of the leading edge of the film storage sheet are clamped and the clamp release state in which the clamping is released. Can be folded automatically. Moreover, since the clamp means is in a wide open state when the film storage sheet is inserted, the film storage sheet can be inserted reliably and easily.

The clamp means is composed of a set of clampers, and a transport roller is arranged at the entrance side of these clampers.
By stopping the rotation of the transport roller during the rotation of the clamper, the film storage sheet is torn off from the perforations, so that one film storage sheet can be easily separated.

Further, since the feeding means is arranged between the pair of clampers so that the feeding means can freely move in and out, the folded film storage sheet can be sandwiched and fed. Further, each clamper is provided with a pair of holding plates, and the width and thickness of these holding plates are gradually reduced toward the tip, so that the holding plates can be smoothly extracted from the folded film storage sheet. it can. Further, since the change of the clamp state and the rotation of the clamper are performed by using one motor and changing the rotation direction thereof, the cost is reduced and the structure is simplified.

When jamming occurs, the movable frame to which the clamper is attached is moved. At this time, the gear attached to the movable frame is separated from the gear of the fixed frame. Since the lock mechanism for preventing the gear of the movable frame from rotating is provided, the rotational position of the clamper does not change before and after the movement of the movable frame.

Since the flexible sheet is arranged on the fixed guide for guiding the film storage sheet toward the clamper, the fixed guide and the sandwiching plate should be widely spaced in order to prevent bending of the film storage sheet. You can Further, since the plurality of holding plates that swing with the rotation of the clamper are provided, the holding plates do not sag during folding of the film storage sheet.
