Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leaflet hopper for supplying a leaflet such as an advertisement to be inserted in a print bag together with a print photograph and a photographic film, and a mounting structure thereof.

[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 printing with different exposure doses, for example, have re-burning marks consisting of one diagonal line and unnecessary print photos such as shooting failures. Is
For example, an unnecessary mark composed of 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 unwanted print photos are placed in a waste bin, and the acceptable prints and the reprinted prints are ejected to a skewed tray. Depending on the width of the paper set in the photo printer, there are 82.5 x 117 mm E size, 89 x 127 mm L size, etc. in one print photograph, and it is twice as long as these sizes. There is a panorama size with.

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 and superimposes the accepted print photograph and the reprinted print photograph discharged to each tray. Next, the printed prints that have been put together are collated with the photo film in the film storage sheet, and these are put in a print bag. 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.

A system for automatically inserting into a DP bag is disclosed in Japanese Patent Publication No. 56-768 and 56-3586.
No. 2, Japanese Patent Application Laid-Open No. 4-70832, No. 4-765.
No. 42 publication. Of these, JP-A-4
No. 76547 discloses an automatic bag filling system that uses two leaflet hoppers to insert two types of leaflets into a print bag together with print photographs. However, since this leaflet hopper has a structure in which the leaflet moves toward the feed roller by gravity on the leaflet receiving plate arranged diagonally, there is a problem that the leaflet cannot be reliably supplied to the feed roller.

The present invention is intended to solve the above problems, and an object of the present invention is to provide a leaflet hopper capable of surely supplying all the set leaflets to a feed roller. .

Another object of the present invention is to provide a leaflet hopper mounting structure in which the leaflet hopper can be easily attached and detached.

[0010]

In order to achieve the above object, the invention described in claim 1 is self-propelled to the front side (downstream side) by gravity on the mounting table between the side edge guides and mounted. A leaflet holder having an inclined surface for keeping the set angle of the leaflet on the table constant, and a free roller attached to the feed roller side of the side edge guide to prevent the set leaflet from tilting forward are provided. . A large number of leaflets set in an oblique state are constantly pushed from the back to the front by a self-propelled leaflet holder, and are received by a free roller, so the last one sheet is fed to the feed roller in an optimal tilted posture. It

According to the second aspect of the present invention, the feed roller is composed of small rollers fixed to the roller shaft with an appropriate interval, and a cutout into which the small roller is inserted is formed at the lower end of the inclined surface of the leaflet holder. It was formed. Since the leaflet holder can fit in the gap between the feed rollers, the last one sheet can be supplied to the feed rollers.

According to a third aspect of the present invention, the reversing roller is rotatably held and is swingably mounted on the mounting base via the mounting shaft, and the supporting frame is swung on the mounting base via the mounting shaft. A fine adjustment frame movably attached, an operation lever for operating a fine adjustment means for adjusting the fine adjustment frame from outside the mounting table, a support frame and a fine adjustment frame on the opposite side of the mounting shaft from the reversing roller. And a zero point adjusting mechanism for changing the connecting length and adjusting the reference position of the reversing roller.

At the time of assembling the leaflet hopper, the zero point adjusting mechanism is adjusted based on the average leaflet thickness.
The zero point adjusting mechanism adjusts the reference position (zero point position) of the reversing roller and sets the distance between the reference roller and the feed roller. The user rotates the operation lever in consideration of the actual thickness of the leaflet and the state of pulling out the leaflet. The operation lever shifts the reversing roller to prevent a drawing failure such as double feed.

According to a fourth aspect of the present invention, a driven gear coaxial with the feed roller is provided, and two hopper mounting pins are provided on both sides of the loading table and on the front side so as to be spaced apart from each other. Is provided with an engaging notch and a drive gear that meshes with the driven gear, and the leaflet hopper is detachably attached to the leaflet conveying device by the engagement of the hopper mounting pin and the engaging notch, and the drive gear and the driven gear are also used. The rotation force of the handbill carrier is transmitted to the feed roller and the reversing roller. Since it suffices to fit two mounting pins on one side into the engaging notches, the leaflet hopper can be easily attached and detached.

[0015]

EXAMPLE FIG. 2 is a schematic diagram showing an automatic bagging system for printed photographs using the leaflet hopper of the present invention.
The paper cutter 11 pulls out the certified paper 13a from the roll paper 13 and conveys it toward the cutting position. During this conveyance, the cut mark sensor detects a cut mark formed of a small hole formed on the side edge portion of the paper 13a. The cutter is operated based on the detection signal of the cut mark to cut the paper 13a into one print photograph 15. Further, a sort mark sensor is arranged on the paper cutter 11, and a sort mark indicating a break of each case is detected, and the cutting work is temporarily stopped based on this to sort each print photograph 15 for each case.

The finished state of each print photograph of the paper 13a has been 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 16 consisting of one diagonal line is the 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 17 composed of two diagonal lines is written.

The print photograph sorting device 14 detects the re-baking mark 16 or the unnecessary mark 17, and based on this, operates each branch guide arranged in the middle of the conveying path to change the conveying destination of the print photograph 15. Thus, the reprint print photograph 15a, the pass print photograph 15b, and the unnecessary print photograph 15c are sorted. The reprinted and passed print photographs 15a and 15b are separately collected.
After sorting one print photo, the integrated print photos 18a and 18b are sent to an elevator 19, and the elevator 19 prints one reprint integrated print photo 18a.
And the passed integrated print photograph 18b are superimposed.
The unnecessary print photograph 15c is sent to the waste box by the branch guide.

In this embodiment, the number of leaflet hoppers 20 is two.
The table is used, and a leaflet 21 on which advertisements and notices of the print service are printed is set on these. These leaflet hoppers 20 are used for the leaflet conveying device 2
It is attached to 2. Each leaflet hopper 20 to 21
Are taken out one by one, and the two types of leaflets are stacked, and then the leaflets are conveyed to the collecting device 23 by the leaflet conveying device 22 in which a plurality of belt pairs and roller pairs are arranged.

The film storage sheet folding device 25 is
Pull out the film storage sheet 26a from the roll 26,
Fold it apart from the perforations made at the boundaries of each case for each case. The folded one film storage sheet 24 is sent to the collecting device 23 by a push plate that slides on the guide. Of the film storage sheets 24 for one case, the pocket containing the first film piece is I
The D number is recorded as a barcode and is read by the barcode reader 25a. Based on this ID number, the ID number of the print photograph written on the LSI card loaded in the paper cutter 11, and the ID number of the check tape attached to the DP bag, it is automatically determined whether or not the three match. Matched.

First, a film storage sheet 24 is supplied to the collecting device 23 from the right side and is inserted into a U-shaped collecting box having both side surfaces and a central portion opened. Next, the leaflet 21 is supplied from behind and placed on the film storage sheet 24 with the centers thereof aligned. Finally, the integrated print photograph 18 is sent from the left to the collecting device 23 and placed on the leaflet 21 with the centers thereof aligned. The integrated print photograph 18 is sandwiched between linearly moving clampers and sent. These three types of contents are
It is assembled with the long one at the bottom. next,
The collection box is rotated 180 degrees about the horizontal axis so that the longest film storage sheet 24 is at the top.

The collected three kinds of contents are sandwiched while being pushed out from the collecting box by the clamper which advances from the back of the collecting box through the central opening, and is sent to the print bag inserting device 27. The flap of the print bag 28 is held by the nip rollers, and the print bag 28 stands by in an inclined state, so that the contents are inserted therein. In the print bag 28, the reprinted integrated print photograph 18a is located at the forefront, so that it is easy to find these in the reprint print process.

When the clamper further advances, the print bag 2
The flap 8 is detached from the nip roller and is inserted into the U-shaped holder which stands by in a horizontal state. During this insertion, the clamper is gradually opened, and a retaining pin for preventing the contents from falling out is erected vertically in front of the print bag 28. Next, the clamper starts retreating in the open state and returns to the initial position while keeping the contents in the print bag 28 in the holder.

When the holder is rotated about a horizontal axis extending in parallel with the print bag 28, the print bag 28 is erected so that the bottom of the print bag 28 faces down. At this time, print bag 2
The flap 28a of No. 8 is temporarily bent, and the print bag 28 is held in the holder by the sandwiching plate. After the holder is rotated, the solenoid of the retaining pin is energized and the lock is released, so that the retaining pin returns to the initial position by the stored force of the spring.

The holder is rotated about a horizontal axis extending in a direction perpendicular to the print bag 28, and the print bag 2 is rotated.
Erect 8 vertically. At this time, since the flap 28 moves while rubbing the receiving plate, it is firmly folded. After the print bag 28 is erected, the holding plate is moved to release the hold of the print bag 28. This printed bag 28
Slides down from the holder under its own weight, and the DP bag insertion device 7
The mouth is opened inside and it enters into the DP bag 29 waiting.
Since the print bag 28 with a small number of prints may not drop due to its own weight, an arm is provided on a chain that is arranged so as to be movable in the vertical direction, and this print bag 28 is used by this arm.
The upper part of is pushed down.

The DP bag 29 containing the print bag 28 is
A signal from the print photo sorting device 14 sorts the image into the reprinted integrated print 18a and the accepted integrated print 18b. The former is shipped to the rebaking process 8 and the latter is shipped. Turned to step 9.

Next, the leaflet hopper will be described in detail. As shown in FIG. 1, the leaflet hopper 20 is folded in two or three in the case of a large size, and about 500 sheets are set on the platform 30 which is arranged to be inclined. Further, sideways guides 31 and 32 whose width can be freely changed are attached to the mounting table 30, and these sideways guides 31 and 32 have a center in the width direction of the leaflet 21 by an interlocking member (not shown). The parallel movement is performed by the same distance so as to always coincide with the center of the platform 30, and the interval is adjusted according to the width of the leaflet 21. In FIG. 1, the groove 35a of the side edge guide 31 is shown, and the movement of the side edge guide 31 is guided by this groove 35a and a pin.

Free rollers 33, 34 are rotatably mounted above the front sides (downstream sides) of the side edge guides 31, 32. The free rollers 33 and 34 receive the front leaflet 21a (see FIG. 4) so that the entire leaflet does not fall forward. The platform 30 is formed in a rectangular box shape, and an upper surface thereof serves as a leaflet receiving plate 35. Further, the side plates 36 and 37 of the mounting table 30 have their front sides protruding upward in a triangular shape, and the feed roller 40 is rotatably attached above the protruding portions.

The reversing roller 41 is rotatably arranged so as to correspond to the feed roller 40, and the interval between the reversing roller 41 and the feed roller 40 is finely adjusted according to the thickness of the leaflet 21. The feed roller 40 rotates clockwise to pull in the leaflet 21a at the forefront, and the reversing roller 41
The leaflets 21 that overlap by rotating clockwise also
Loosen the lower end of the to prevent double feed. The feed roller 40 and the reversing roller 41 are composed of four small rollers 40a and 41a, and are arranged at appropriate intervals on the rotating shaft 4
It is fixed to 0b and 41b. In addition, by forming an annular groove on one long roller so as to have a small diameter portion,
It may be a substantially small roller.

Rotating shafts 40b, 41 of the rollers 40, 41
Gears 42 and 43 are attached to the shaft end portion of b,
As shown in FIG. 6, these gears 42 and 43 are interlocked via an idle gear 44. In addition, the feed roller 40
A driven gear 47 for receiving a rotational force from the leaflet transport device 22 and an electromagnetic clutch 48 are provided on the shaft end of the rotary shaft 40b of the.
And are attached. The driven gear 47 meshes with the drive gear 49 of the leaflet conveying device 22. The electromagnetic clutch 48 selectively rotates the driven gear 47 to rotate the gear 42.
And is controlled by the controller of the leaflet conveying device 22.

When sending out one leaflet 21 from the leaflet hopper 20, the electromagnetic clutch 48 is turned on,
The rotation of the driven gear 47 meshing with the drive gear 49 is transmitted to the gear 42, and the feed roller 40 is rotated by the rotation shaft 40b. At the same time, the rotation of the gear 42 is transmitted to the gear 43 via the idle gear 44 to rotate the reversing roller 41. The feed roller 40 pulls out the leaflet by frictional force, and feeds the leaflet to the pair of conveyance rollers 50 installed in the leaflet conveyance device 22 through the gap CL with the reversing roller 41. When a sensor such as a micro switch detects that the conveyance roller 50 has caught the leaflet 21a, the controller turns off the electromagnetic clutch 48.
Then, the driven gear 47 and the gear 42 are separated from each other. Since the pair of conveying roller pairs 50 are continuously rotating, one leaflet 21a taken out from the leaflet hopper 20 is sent to the collecting device 23 via the leaflet conveying device 22.

Since the reversing roller 41 is rotating in the same direction as the feed roller 40, it gives the leaflet 21 a conveying force in the opposite direction. Therefore, the first leaflet 2
It prevents double feed in which the next leaflet 21b is pulled out simultaneously with 1a. Further, as shown in FIG. 4, a stainless thin plate 45 is disposed between the small rollers 41a on the leaflet entrance side of the reversing roller 41. The thin plate 45 prevents the tip of the leaflet from being bent by the reverse feed of the reversing roller 41. The optical sensor 52 detects that there is no leaflet in the leaflet hopper 20.

As shown in FIGS. 1 and 5, a leaflet holder 55 is provided on the platform 30 between the side edge guides 31 and 32 so as to be movable in the leaflet feeding direction of the platform 30. The leaflet holder 55 includes an inclined plate 55a and a substrate 55.
It is almost V-shaped due to b. Inclined plate 55a
Pushes the back of the leaflet 21 on the platform 30 at a constant angle. Four feed rollers 56 also serving as weights are rotatably attached to the substrate 55b, and the leaflet holder 55 is lowered on the leaflet receiving plate 35 by gravity. Further, a guide plate 57 protruding downward is formed on the substrate 55b, and this portion enters a slit 58 formed in the leaflet receiving plate 35 and guides the movement of the leaflet holder 55.

At the tip of the leaflet holder 55, a notch 60 is formed at a position corresponding to the small roller 40a of the feed roller 40, into which the small roller 40a is inserted. As a result, the leaflet holder 55 becomes the feed roller 4
Even if the leaflet is the last one, it is sure to feed it into the feed roller 40.

As shown in FIGS. 5-7, the reversing roller 41
In order to prevent feeding failure and double feed of the leaflet, a gap adjusting mechanism 65 that adjusts the gap CL between the leaflet 40 and the feed roller 40 is provided. The gap adjusting mechanism 65 includes a support frame 66 and a fine adjustment frame 6.
7, screw rod 68, fine adjustment nut 69, adjustment lever 70,
It is composed of a zero adjustment screw 71. Support frame 66
Holds the reversing roller 41 rotatably, and is swingably attached to the mounting table 30 by a mounting shaft 72.

When the support frame 66 is swung with the mounting shaft 72 as the center of rotation, the amount of meshing between the idle gear 44 and the drive gear 43 of the reversing roller 41 changes slightly. However, the lift amount of the reversing roller 41 by the gap adjusting mechanism 65 is a slight amount corresponding to the change in the leaflet thickness, and even a slight change in the meshing amount does not adversely affect the actual drive transmission. In order to positively eliminate the change in the meshing amount between the idle gear 44 and the drive gear 43 that occurs in response to the change in the lift amount of the reversing roller 41, the support frame 66 is coaxial with the rotation shaft of the idle gear 44. It is good to attach.

The fine adjustment frame 67 is swingably attached to the mounting table 30 via a mounting shaft 72. A screw rod 68 is fixed to a center portion of the fine adjustment frame 67 by a mounting pin 73. The screw rod 68 is screwed to a fine adjustment nut 69 rotatably attached to the mounting table 30 via a bracket 75. An adjustment lever 70 is fixed to the fine adjustment nut 69, and the rear end of the adjustment lever 70 extends to the upstream side below the mounting table 30 as shown in FIG. Is attached.

According to the thickness of the leaflet 21, the adjusting screw 76 is pinched with a finger so as to match any one of the "T", "M" and "L" indexes provided on the lower surface of the table 30. When the adjustment lever 70 is rotated, the screw rod 68 moves in the arrow direction, and the support frame 66 and the fine adjustment frame 67 are integrally attached to the mounting shaft 72.
The reversing roller 41 is shifted by rotating it around. If the adjusting screw 76 is tightened after this, the adjusting lever 70
Is fixed. The screw rod 68 has coil springs 77a, 7
7b is fitted, and the screw rod 68 and the fine adjustment nut 69 are attached.
It is urged so that there is no looseness in the installation. In addition,
Reference numerals 78a to 78c are rings, and reference numeral 79 is a stop pin for preventing the ring 78c from coming off the screw rod 68.

Further, a zero point adjusting mechanism 71 for setting the clearance CL between the feed roller 40 and the reversing roller 41 to a reference value at the time of assembly at the factory is provided. The zero-point adjusting mechanism 71 includes a mounting screw 80, a lock-fastening nut 81 screwed to the mounting screw 80, a support frame 66, and a fine adjustment frame 67.
And a coil spring 82 that urges and away from each other. When the nut 81 is turned, the distance between the support frame 66 and the rear end side of the fine adjustment frame 67 is adjusted against the coil spring 81, whereby the reversing roller 41 is shifted. In the zero-point adjusting mechanism 71, when the center distance 2L between the zero adjusting mechanism 71 and the mounting shaft 72 is equal to the mounting shaft 72 and the reversing roller 41, or the screw rod 68.
Since it is twice the distance L between the centers of
Is transmitted to the reversing roller 41 through the rings 78a to 78c and is transmitted to the zero point adjusting mechanism 71 at a ratio of 1: 2, so that delicate adjustment can be performed.

As shown in FIG. 5, both side plates 3 of the mounting table 30.
Two hopper attachment pins 85 and 86 are attached to the Nos. 6 and 37 so as to be separated from each other. In addition, the leaflet carrier device 22
At the position where the leaflet hopper 20 is attached, the engagement notch 8 into which the attachment pins 85 and 86 enter the machine frame 87
8, 89 are formed. The upper engagement notch 88 has an opening 88a on the lower side and is elongated in the vertical direction. The lower engagement notch 89 has an opening 89a at the upper side.

When attaching the leaflet hopper 20, first, the upper attachment pin 85 is inserted into the upper engagement notch 88, and if the rear end of the leaflet hopper 20 is lowered in this state, the lower attachment pin 86 will become the lower engagement notch 89. To insert. After this insertion, the moment due to the own weight of the leaflet hopper 20 is exerted, the upper mounting pin 85 is pushed toward the inner side of the upper engaging cutout 88, and the upper mounting pin 86 enters the inner side of the lower engaging cutout 89. Since it is pushed, the leaflet hopper 20 is stably attached to the machine frame 87 of the leaflet conveying device 22.

Next, the operation of this embodiment will be briefly described.
As shown in FIG. 1, the side edge guide 3 of the leaflet hopper 20.
After matching the widths of the leaflets 1 and 32 with the width of the leaflet 21, a large number of leaflets are set on the leaflet receiving plate 35 between the side edge guides 31 and 32. These leaflets 21 are pushed from behind by the leaflet holder 55 at an angle ideal for feeding leaflets. As shown in FIG. 4, the foremost leaflet 21a is in contact with the feed roller 40 and the upper portions thereof are in contact with the free rollers 33, 34, whereby the leaflet is at an ideal angle for pulling in the leaflet. The posture of 21a is maintained.

The controller of the leaflet conveying device 22 turns on the electromagnetic clutch 48 when the leaflet is supplied. As a result, the rotation of the driven gear 47 meshed with the drive gear 49 on the handbill carrier device side causes the rotation of the gear 4 via the electromagnetic clutch 48.
2 and the feed roller 40 rotates in the direction of pulling out the leaflet 21a. In addition, the reversing roller 4
1 rotates in the same direction as the feed roller 40 via the idle gear 44, and prevents double feeding of the next leaflet 21b following the most advanced leaflet 21a.

The feed roller 40 draws the most advanced leaflet 21a by its frictional force, and causes it to be caught in the pair of transport rollers 50 of the leaflet transport device 22 through the gap CL with the reversing roller 41. When this bite is detected by the sensor, the electromagnetic clutch 48 is turned off, so that the rotation of the driven gear 47 is not transmitted to the feed roller 40 and the reversing roller 41. However, since the pair of conveying rollers 50 rotates as it is, one taken out leaflet 21 a is conveyed by the leaflet conveying device 22.

In the same manner, each time a leaflet disappears from the leaflet standby position of the leaflet transport device 22, the leaflets are successively supplied to the leaflet transport device 22. When the leaflet disappears, an optical sensor provided in the leaflet hopper 20 detects this, and the controller issues an alarm. Also,
When the number of leaflets becomes small, a part of the leaflet holder 55 enters between the small rollers 40a, so that the last leaflet can be reliably pulled out.

When the thickness of the leaflet is changed or the feeding is unstable, loosen the adjusting screw 76 and then rotate the adjusting lever 70. This adjustment lever 70 allows the nut 6
Since 9 rotates, the screw rod 68 moves up and down, and the mounting shaft 72
The support frame 66 and the fine adjustment frame 67 are rotated together around. As a result, the reversing roller 41 attached to the support frame 66 shifts, so that the clearance CL with the feed roller 40 is adjusted to an optimum value.

When the leaflet hopper 20 is removed from the leaflet carrier device 22 for repair or the like, the leaflet hopper 2 is used.
If you hold the rear end side of 0 by hand and lift it up, the lower side mounting pin 8
6 comes out from the lower engagement notch 89. Next, if the front side of the leaflet hopper 20 is shifted slightly downward, the upper attachment pin 85 comes out of the upper engagement notch 88. In this state, if the leaflet hopper 20 is moved backward, it can be detached from the leaflet carrier device 22. If the reverse procedure is performed, the leaflet hopper 20 will move the machine frame 8 of the leaflet conveying device 22.
7, the driven gear 47 meshes with the drive gear 49 of the leaflet transporting device 22.

[0047]

As described above, according to the present invention,
In addition to mounting the platform on the flyer transporting device at an angle, a flyer holder is also installed on this platform, which is self-propelled by gravity and presses the backside of the leaflet diagonally. Can be sent to the side. Further, since the leaflet holder is provided with the inclined surface, the leaflet can be always held on the platform at a constant angle.
Moreover, the free rollers are provided on the side edge guides so as to be positioned above the feed roller, so that the leaflet is always contacted with the feed roller and the reversing roller at the optimum inclination angle, thereby reliably preventing double feed of the leaflet. it can.

Further, since the feed roller is composed of a plurality of small rollers, and a cutout for inserting the small roller is formed in the inclined plate of the leaflet holder in accordance with the small rollers, the final leaflet is also supplied to the feed roller. be able to.

Further, since the reversing roller is rotatably attached to the supporting frame and the supporting frame is slightly rotated by the fine adjustment mechanism, the gap between the feed roller and the reversing roller is set in accordance with the thickness of the leaflet. It can be adjusted optimally. This prevents the front leaflet and the next leaflet following the leaflet from being pulled out in an overlapping manner.

Further, two hopper mounting pins are separately mounted on the loading table side, an engaging notch is provided on the leaflet conveying device side, and the leaflet hopper is mounted by the hopper mounting pin and the engaging notch. This makes it easy to install the leaflet hopper. Moreover, since the driven gear is fixed coaxially with the feed roller, and the drive gear that meshes with the driven gear is provided on the leaflet conveying device side,
The feed roller can be rotated from the leaflet carrier device side via the drive gear and the driven gear. Therefore, it is not necessary to dispose a motor or the like for rotating the feed roller on the leaflet hopper side, and the configuration can be simplified.
