A storage device 9 that stores banknotes in bulk after they have been accumulated.
is provided.

The extraction device 5 will be explained based on FIG. 2 and FIGS. 3a and 3b. In the figure, reference numeral 11 denotes a supply unit that collectively supplies a plurality of banknotes P stacked in the plane direction. is in an upright position in contact with a guide plate 13 erected on the substrate 12, and is held by a backup plate 14. The backup plate 14 is connected to a biasing mechanism (not shown) and is elastically pressed in the direction of the second arrow A in the drawings. On the side facing the backup plate 14, a take-out belt 16 stretched around a plurality of rollers 15 is configured to be rotated in the direction of the second arrow B in the figure, and is in contact with the take-out belt 16. A friction feed-out roller 17 that is driven to rotate in a counterclockwise direction is provided at the front end in the longitudinal direction of the banknote P.
A sheet feeding prevention section 18 is provided.

This two-sheet feed prevention section 18 is made up of an endless friction belt 19 having a certain degree of elasticity, and is prevented from rotating via appropriate means after being stretched over posts 21 and 21' protruding from the sub-base 20. It is fixed as follows. In the friction delivery roller 17, a low friction portion 17a is formed in a portion facing the endless friction belt 19, and an intermediate portion of the endless friction belt 19 is suitable for the low friction portion 17a of the friction delivery roller 17. They are in a slightly bent state due to pressure contact. Note that 22 is an eccentric post attached to the sub-base 20, and by rotating this post, the deflection state of the endless friction belt 19 can be finely adjusted.

Further, in front of the double-sheet feed prevention section 18, a double-sheet feed prevention section 23 is provided. A holder 24 is installed upright on the sub-base 20, and a tongue-shaped guide plate 25, a tongue-shaped flexible friction piece 26 made of silicone rubber, etc., and a friction coefficient such as mylar paper are attached to the holder 24. A small flexible low friction piece 27 in the shape of a tongue is successively superposed on top of the other, and is fixed by a mounting plate 28. The tip of the friction piece 26 protrudes beyond the tip of the low-friction piece 27, so that the tip of the second and subsequent banknotes P taken out from the supply section 11 in the take-out direction comes into contact with the low-friction piece 27. It's getting old.

The take-out device 5 configured in this way has a supply section 11
The banknotes P supplied are pressed against the backup plate 14, and as the take-out belt 16 rotates, the first banknote at the forefront is moved in the side direction due to friction with the take-out belt. At this time, the subsequent banknotes are also moved due to the friction between the second and subsequent banknotes P, but they are stopped by the low friction piece 27 and prevented from taking two banknotes. In particular, since the friction coefficient of the low-friction piece 27 is small, bending of the tip of the banknote that is locked thereon is completely prevented. Note that when the tips of the first and second banknotes P pass through the low-friction piece 27 at the same time, the second banknote P is braked by the friction piece 26 and the endless friction belt 19. So this is 2
The banknotes P are not sent out from between the friction delivery roller 17 and the endless friction belt 19 in a stacked state, but are sent out one by one.

In addition, instead of the above-mentioned take-out device 5, the main part is shown in FIG. 4a,
It is also possible to configure as shown in b. That is, a friction member 30 is fixedly attached to the upper end of the post 21, and the friction member 30 is formed by attaching a relatively thin friction body, for example, an O-ring 30a, to the circumferential surface of a base body, for example, a disk 30b, having a curved portion. A double-cutting prevention guide 31 having a shape substantially along a part of the outer edge of the guide 30a is attached to the post 21, thereby forming a double-cutting preventing portion 23. The O-ring 30a is adapted to come into contact with the surface above the central part in the height direction of the frontmost banknote P that is sent out in an upright position. Further, the friction feed roller 17 is provided with a relief portion 17b that prevents the outer edge of the O-ring 30a from coming into contact with it. Further, in order to finely adjust the distance between the outer edge of the O-ring 30a and the tip of the double-sheet prevention guide 31 and the friction feed roller 17, the post 21 can be eccentrically rotated to adjust its rotational position relative to the sub-base 20. This can be done via an adjustment lever 32 provided at the upper end of the post 21. The rest of the configuration is almost the same as that shown in FIGS. 3a and 3b, so detailed explanation will be omitted.

The take-out device configured in this way is configured to adjust the O to the relief portion 17b via the adjustment lever 32
If the amount of insertion of the outer edge of the ring 30a is adjusted to the extent that one bill P can pass through, the O-ring 30
Since the amount of elastic deformation of a is extremely small and the second and subsequent banknotes P are reliably locked in the double-removal prevention guide 31, the banknotes can be taken out while reliably preventing double-removal of the banknotes P. Ru. Further, since the second and subsequent bills P are in smooth contact with the double-bill prevention guide 31, bending of the leading edge is completely prevented. Furthermore, when the banknote P is taken out and sent out between the frictional delivery roller 17 and the O-ring 30a, the upper part of the banknote P is frictionally braked by the O-ring 30a, so that the lower side of the banknote P is It is brought into close contact with the substrate 12, and the banknotes P can be stably fed out without skewing, thereby making it possible to prevent banknotes from jamming.

The longitudinal conveyance device 6 will be explained based on FIG. 2. This is the friction feed roller 17 of the take-out device 5.
a longitudinal conveyance section 40 that holds and conveys banknotes P sent out from the bank in the longitudinal direction, and this longitudinal conveyance section 40;
A detection unit 41 and a direction conversion unit 42 provided in the middle part of
It is composed of. The longitudinal conveyance section 40 includes a plurality of guide rollers 43 and conveyor belts 44, 45,
46 and 47 are strung together so as to run endlessly, and the bill P is held between these conveyor belts 44 to 47 and conveyed in the direction of the second arrow C in the figure. The detection unit 41 determines the denomination, authenticity, front and back, etc. of the banknotes conveyed by the conveyance unit 40, and determines the denomination, authenticity, front and back, etc. of the banknotes P by optically scanning the surface of the banknotes P being conveyed. Configured to read a pattern and compare the value obtained by integrating the read pattern with the value obtained by integrating the preset standard pattern in four directions for each denomination, front, back, forward, and reverse. has been done. The direction changing unit 42 stops the banknote P which is normal as a result of the determination by the detection unit 41 through appropriate means, and switches to short-side conveyance by pinching both sides of the banknote through an appropriate means. It is configured.

The longitudinal conveyance device 6 configured in this manner grips and conveys the bill P sent out from the friction feed roller 17 of the take-out device 5 in the longitudinal direction, and detects the trueness of the bill P by the detection unit 41 during conveyance. A banknote P which is determined to be a fake or the like and which is normal as a result of the determination is switched to short-side conveyance by the direction conversion unit 42, and an abnormal banknote P passes through the direction conversion unit 42 and is rejected to the reject port 4. becomes.

The short-side conveying device 7 will be explained based on FIG. 5. This is the direction changing section 42 of the longitudinal conveyance device 6.
A transversal conveying section 50 transversely conveys the banknotes P which have been switched to transversal conveyance, and a sorting section 51 that sorts the banknotes P transversely conveyed by this into each denomination.
It is composed of. The short-side conveying section 50 is configured by conveying belts 53, 54, 55, 56, 57 wrapped around a plurality of guide rollers 52, 52a, 52b so as to run endlessly. 5th illustrated arrow D
It extends downward from the direction changing section 42 and horizontally from the lower end. The dividing section 51 is constituted by swingable dividing gates 58a, 58b, 58c provided near each of the guide rollers 52a, and a separating guide 59 fixedly provided near the guide rollers 52b. gate 58a
58c is fitted onto a rotating shaft of a rotary solenoid (not shown) so that it can be rotated.

The transverse transport device 7 configured in this manner transports the banknotes P delivered from the direction changing section 42 in the transverse direction while sequentially holding them via the transport belts 53 to 57. As a result of the denomination determination by the detection unit 41, the denomination of the banknote being conveyed in the short direction is, for example, 1.
In the case of a ten thousand yen bill, the rotary solenoid (not shown) is energized and the sorting gate 58
a is rotated upward from the state shown in FIG. 5, and the bill is guided by this sorting gate 58a and conveyed downward in FIG.
a is returned to the state shown in FIG. In the case of a 5,000 yen bill, the sorting gate 58b operates in the same manner as described above, and in the case of a 1,000 yen bill, the sorting gate 58c operates in the same manner as described above. In the case of 500 yen banknotes, use the classification guide 59.
It is naturally guided and conveyed downward in FIG. The banknotes being conveyed laterally are thus sorted by denomination by the sorting section 51.

The integration device 8 will be explained based on FIGS. 5 to 7. As shown in FIG.
, a second accumulation section 60b provided below the sectioning gate 58b, a third accumulation section 60c provided below the sectioning gate 58c, and the sectioning guide 59.
The stacking sections 60a to 60d have substantially the same configuration and collect banknotes guided through the sorting gates 58a to 58c and the sorting guide 59. It is composed of an impeller mechanism 61 for stacking bills in the surface direction, and a storage box, such as a stacking box 62, for guiding and stacking the edges of banknotes.

The specific configuration of the impeller mechanism 61 and the collection box 62 is as shown in FIGS. 6 and 7.
A support shaft 65 is pivotally supported by a bearing 67 provided on a side frame 66.
A driven pulley 68 is fitted to the end protruding from 6. Further, a drive motor 69 is provided on the side frame 66, and a belt 7 is provided between the drive pulley 70 pivotally connected to the drive motor 69 and the driven pulley 68.
1 is stretched. An impeller 72 is attached to the middle part of the support shaft 65, and this
The ring-shaped impeller main body 72a is composed of a plurality of blade plates 72b whose proximal end protrudes radially from the peripheral surface of the impeller main body 72a and is bent in a predetermined direction. Further, each blade plate 72b is formed in a spiral shape, with a wide interval between the tips and gradually narrowing toward the base end. Further, the blade plate 72b
As shown in FIG. 7, they are attached outside the fold P ₁ of the banknote P at a distance that allows the fold P ₁ to be avoided. Although not shown, it goes without saying that folds can be avoided even if the bill P is folded in two, and especially when setting the spacing between the blades 72b, the largest size 10,000 yen bill can be avoided. By using this as a standard, folds can naturally be avoided even for low-denomination banknotes. In this way, the vane plate 7
2b makes it possible to reliably insert the banknotes P between the blade plates 72b even if the banknotes are slightly creased, making it possible to completely prevent banknotes from jamming in the blade wheel 72. Further, the support shaft 65 is provided with, for example, a spring clutch 73, which is connected to an input hub 73a fitted to the support shaft 65, and is fitted to a part of the outer peripheral surface of the input hub 73a. an output hub 73b to which the input hub 73a and the output hub 73b are attached, and a spring 73c wound around part of the circumferential surfaces of the input hub 73a and the output hub 73b.
and a stopper 73d engaged with the spring 73c. Furthermore, Stoppa 7
3d is provided with two grooves, and two magnets are disposed along the circumferential surface of the groove at a predetermined distance from each other. (None of these are shown.) A magnet comes into contact with and separates from the groove. Further, the segmented and integrated board 74 is bent along the outer periphery of the blade plate 72b, and a portion thereof extends in the circumferential direction from the tip of the blade plate 72b. This direction of extension is opposite to the rotational direction of the impeller 72 (direction of arrow E in the sixth figure). Furthermore, as shown in FIG.
a left side wall plate 75a having a notch (not shown) through which banknotes P can pass; and a right side wall plate facing the left side wall plate 75a with a space where banknotes P can be piled up and piled up in the surface direction. 75b and a back wall plate 75c provided at the back, and a transparent acrylic board (not shown) is provided on the front so that it can be opened and closed. Each of the wall plates 75a to 75c has linear convex portions 75' formed along the falling and moving direction of the banknotes, that is, the stacking direction of the banknotes (direction of arrow F in the sixth figure), and at least the surface thereof is conductive. It is constructed of a plate material, for example, an embossed metal plate (see FIGS. 9 and 10). Each wall plate 75a to 7 is formed by the metal plate embossed in this way.
5c, the contact area with the banknotes P can be reduced, so the banknotes P can be dropped smoothly.
4, 55, 56, 57, the static electricity generated on the banknote is removed by the linear protrusion 7 of the embossed metal plate.
5', it is possible to completely eliminate abnormalities in the falling of banknotes and uneven accumulation of banknotes due to the influence of static electricity. Note that each of the wall plates 75a to 7
5c can also be replaced with one constructed by plating a conductive layer on the surface of an embossed plastic plate.

The operation of the thus configured stacking device 8 will be explained. The banknotes sorted by denomination by the sorting section 51 are stored in the first stacking section 6 according to the denomination.
0a to the fourth stacking section 60d, for example, the first stacking section 60a.
When a 10,000 yen bill is transported, it is transported through the sorting gate 58a toward the impeller 72, which rotates in the direction of the sixth arrow E in the figure. At this time, the impeller 72
is rotated at a circumferential speed that is approximately half the banknote transport speed in the short transport section 50. Clutch 73 is actuated to maintain compartment stacking plate 74 at a corresponding position within stacking box 62 as shown. Bills P are inserted between the blade plates 72b of the impeller 72, and are conveyed while being held between the blade plates 72b and the impeller body 72a. As the impeller 72 rotates, the banknotes P are transferred to the sorting and stacking board 7.
4 to be placed on top.

When a predetermined number of banknotes P are stacked on the sorting and stacking board 74 in this manner, the magnet (not shown) is energized and the stopper 73d of the clutch 73 is released. The so-called clutch is in the engaged state, and the rotational force of the support shaft 65 is transmitted to the sectional accumulation plate 74. Then, the sorting stacking plate 74 rotates together with the impeller 72 in the direction of the sixth arrow E in the figure, and the stacked banknotes are squeezed into a notch (not shown) of the stacking box 62 and fall onto the partition 80 of the storage device 9, which will be described later. . Further, the banknotes P subsequently conveyed by the impeller 72 directly overlap the group of banknotes on the partition section 80 . When the sorting/accumulating plate 74 reaches the front side of the sorting gate 58a, the stopper 73d collides with the magnet and the clutch 73 is actuated. The so-called clutch is in a disengaged state, and the sorting/accumulating plate 74 is stopped at the position shown in FIG. 6, and banknotes are subsequently accumulated in the same manner.

The storage device 9 is shown in FIGS. 5 and 8 to 11.
This will be explained based on the diagram. As shown in FIG. 5, the storage device 9 has a schematic configuration including a partition section 80 made up of a plurality of partition plates, a relative movement mechanism section 81 that relatively moves each partition plate back and forth, and a drive section 82 that moves the partition plates. a partition mechanism 79 consisting of;
A storage section 100 is provided below each of the stacking sections 60a to 60d.

The concrete structure of the partition mechanism 79 is shown in FIGS. 8 to 10. 8 is a schematic front view of the storage device 9, FIG. 9 is a schematic top view of the partition mechanism 79, and FIG. 10 is a schematic right side view of the partition mechanism 79. The partition part 80 includes a fixing plate 83 fixed in the main body 1, guide rails 84 and 85 attached to both sides of the fixing plate 83, and guides provided on these guide rails 84 and 85 so as to face each other. Grooves 84a, 85a and both guide grooves 84a, 8
A first partition plate 86 that can engage with 5a and move back and forth
and a second partition plate 87, and the second partition plate 87 is arranged so as to be movable above the first partition plate 86. The second partition plate 87 is bent so as to form a convex portion 87a at the center, and a protrusion 88 is attached to the front side (the left side in FIGS. 9 and 10). This protrusion 88 floats the front end of the banknotes P stacked on both the partition plates 86 and 87, and allows the stacked banknotes to be taken out (from the storage section 100 described later).
This is to simplify and speed up the process (which is necessary when banknotes are not stored in the bank). Note that the convex portion 87 formed on the second partition plate 87
It is also possible to obtain substantially the same effect as when the protrusion 88 is provided by using the projection 88. In addition, the collection box 6
An escape notch 75a' (see FIG. 10) for escaping the second partition plate 87 is formed at the lower end of the second left side wall plate 75a. Especially this relief notch 75
Since a' is approximately in line with the shape of the second partition plate 87, the banknote P is placed on the second partition plate 87 and the second partition plate 87 is moved along the direction indicated by the ninth arrow G. Even if the banknotes P are moved in the direction
7 and the escape notch 75a' can be prevented. Further, two guide rails 89 are attached to the surface of the first partition plate 86 at intervals, and two pairs of guide rollers 89 are attached to the back surface of the second partition plate 87 so as to sandwich the guide rails. 90 is attached to facilitate relative movement of both partition plates 86, 87.

The relative movement mechanism section 81 employs, for example, a so-called pantograph mechanism. That is, the first
A link 81a and a second link 81b are rotatably supported on the surface of the fixed plate 83, and a third link 81c and a fourth link 81d are rotatably supported on the back surface of the first partition plate 86. It is pivoted so that it can move freely,
Further, the free end of the first link 81a and the free end of the third link 81c are rotatably supported, and the free end of the second link 81b and the free end of the fourth link 81d are rotatably supported. are rotatably supported. The pivot point between the first link 81a and the third link 81c and the second link 81b
Rollers 91A and 91B are installed above the pivot points of the and fourth link 81c, respectively, and these rotors 91A and 91B are inserted into a pair of elongated holes 87A and 87B provided in the second partition plate 87. (Second partition plate 87
(provided in a direction perpendicular to the direction of movement).

The drive section 82 has a front bracket 94 attached to a side holder 93 attached to the main body 1, and a reversible motor 95 is disposed on the front bracket 94. And this reversible motor 9
A grooved cam 96 is fitted onto the motor shaft of No. 5.
Further, one end of a cam lever 97 is swingably supported on the front bracket 94, and a cam follower 98 is attached to the middle part of the cam lever 97 and is engaged with the cam groove 96a of the grooved cam 96. The other end of 97 is engaged with an engagement hole 87b provided in the second partition plate 87. Note that when the lower end closing portion 62a of the accumulation box 62 and the later-described upper end opening portion 101a of the storage portion 100 are completely closed by the partition plates 86 and 87 (as shown in FIG. 9), that is, the cam follower 98 is at the starting end 96b of the cam groove 96a, the straight line connecting the axis of the reversible motor 95 and the center of the cam follower 98 becomes almost parallel to the moving direction of both the partition plates 86 and 87, forming a dead center. , both partition plates 86,8
7 can be prevented from being manually opened and closed.
This has the unique effect of ensuring the safety of the banknotes stored therein. Although not shown, a timing cam is attached to the tip of the motor shaft of the reversible motor 95, and the cam follower 98 is connected to the starting end 96b and the terminal end 96 of the cam groove 96a.
When reaching c, a micro switch (not shown) is activated, and the rotation of the reversible motor 95 is controlled via an appropriate control device based on the output from this micro switch. .

The specific configuration of the storage section 100 is as shown in FIGS. 8 and 11, and the partition section 80
A storage box, such as a safe 101, is disposed below the main body 1 and is detachably attached to the main body 1. This safe 101
The safe has an upper end opening 101a and a storage chamber 101b formed therein, and is further provided with a guide groove 101c for the cover plate 102 along the upper edge. Part 10
1a can be closed and locked. A detector 11 is located near the top of the safe 101.
0 transparent holes 101d are formed facing each other. A backup board 103 is inserted into the safe 101. One end of the backup plate 103 protrudes from a vertically elongated guide hole 104 formed in one side wall of the safe 101. The elevator mechanism 105 engages with this protruding end. In other words, two pulleys 1 are pivotably supported apart from each other in the vertical direction.
A belt 107 is looped around the belt 106 so as to run endlessly, and one pulley 106 is connected to a drive motor 108 that can freely rotate in forward and reverse directions. A hook 109 having a groove 109a is attached to a part of the belt 107. The protruding end of the backup plate 103 engages with the groove 109a of the hook 109, and when the detector 110 detects the passage of a banknote, the drive motor 108 is driven, and the backup plate 10
3 can be gradually lowered inside the safe 101. Then, when the safe 101 is moved in the direction of the groove 109a, the backup plate 103 moves toward the groove 109a.
It is designed to be detachable from 9a.

In the storage device 9 configured in this manner, when the grooved cam 96 is rotated in the direction of the eighth arrow J in the figure via the reversible motor 95, the cam lever 97 is moved to the third position by the action of the cam follower 98 that engages with the cam groove 96a. 8 Rotated in the direction of arrow K shown in the figure. This rotation is transmitted to the second partition plate 87 through the engagement hole 87b, and moves it in the direction of the ninth arrow G in the figure.
At this time, the rotor 91A moves through the elongated hole 87A in the direction of the ninth arrow L, and the rotor 91A moves in the direction of the ninth arrow L in the figure.
B moves through the elongated hole 87B in the direction of the ninth arrow M in the figure, so the first partition plate 86 is also moved in the direction of the ninth arrow G in the figure via the third and fourth links 81c and 81d. Note that the first to fourth links 81
Since a to 81d constitute a so-called pantograph mechanism, the moving speed of the first partition plate 86 is approximately twice that of the second partition plate 87.
Therefore, when the cam follower 98 reaches the terminal end 96c of the cam groove 96a, it almost overlaps both the partition plates 86 and 87, and the lower end opening 62a of the collection box 62 and the upper end opening 101a of the safe 101
The banknotes P accumulated on both the partition plates 86 and 87 are dropped onto the backup plate 103. Then, the dropped bill P is detected by the detector 1.
The backup board 103 is lowered until it no longer blocks the back up plate 10. Thereafter, the cam 96 is reversed, and the partition plates 86 and 87 return to the positions shown in FIG. 9, allowing the banknotes P to be stored in the safe 101.

Such a storage device 9 is provided with a two-stage partition mechanism 79 consisting of first and second partition plates 86, 87, etc., so both partition plates 86, 87, etc.
The movement space required for opening and closing the safe 87 can be reduced to about half that of a conventional one-stage type, and as a result of narrowing the distance between the safes 101, it is possible to achieve a smaller storage device. .

The display operation device 2 is configured as shown in FIG. 12, and includes a power switch 111, a mode designation switch 112, a confirmation key 113, a numeric keypad 114,
It is composed of an operation key group 115, a display section 116, a card insertion slot 117, and a slip issuing slot 118.
