A thermometer is fitted to the sidewall of the motor 700. When an external temperature falls and the surrounding temp. of the motor 700 falls 5 deg.C on below e.g. heat is generated in the motor 700 by increasing the quantity of current allowed to flow into the motor 700 when the motor 700 is stopped. The heat generating amount is set up to a value sufficient for holding the motor 700 at about 5 deg.C.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bill storage device having a function of transferring a bill to at least one of an inside and an outside of a storage room.

[0002]

2. Description of the Related Art Heretofore, currency exchange machines and vending machines installed on the streets, financial institutions or playgrounds have been provided with a bill storage device for storing or paying out bills. Since exchange machines and vending machines need to be installed in a limited space, they must be as small as possible.

[0003] Also, unless a certain amount of commodities such as drinking water is stored in the vending machine, it must be replenished frequently, so that the space for storing commodities and the like must be as wide as possible. is there. Therefore, the bill storage device built in the vending machine is required to be small. On the other hand, exchange machines are often placed adjacent to vending machines and coin lockers, or at corners of gaming machines in pachinko parlors, game centers, and the like. Therefore, there is a strong demand for miniaturization of money changers.

[0004] On the other hand, vending machines and money changers are often used in unmanned environments regardless of whether they are installed indoors or outdoors. For example, the number of places where various vending machines are recently gathered, such as in a parking area of a highway, is increasing. Since such exchange machines and vending machines are installed for the purpose of efficiency and labor saving, they are required to be so-called highly reliable devices which cause less trouble when depositing and dispensing banknotes. .

[0005] Moreover, since the object to be handled is money,
Higher reliability is required compared to other types of devices. The bills to be handled are rarely new bills, but rather are used bills with folds, dirt, and sometimes missing. In addition, the bills used are not limited to genuine bills, and may be counterfeit bills (including foreign bills). In addition, considering that all kinds of bills can be used, the bills can be identified and billed. There is a need for a mechanism that smoothly and accurately carries in and out of the container. Furthermore, because there is also a need to shorten the bill processing time, in addition to the smooth and accurate bill handling,
Quickness is also required.

Incidentally, the bill storage device usually has a structure in which bills are conveyed into and out of the device by rollers, belts, and the like connected to a motor via gears. When the transport of the bills is started, the motor that has been stopped is rotated, while when the transport of the bills is stopped, the rotating motor is stopped. Then, in order for the bill storage device to perform bill processing accurately and promptly, in addition to accurate control of driving and stopping of the motor, accurate control of a rotation speed and a rotation direction is performed.

[0007]

However, the above-mentioned bill storage device has the following problems. The bill storage device may be installed in a low-temperature environment. When the motor is rotating, the motor is radiating heat to some extent, so that the motor and other components are warmed. However, when the motor is stopped, the motor is placed under almost the same environment as the outside air. Therefore, when a motor or a roller that has been stopped for a long time starts to move due to a request for depositing and dispensing banknotes, these may not operate properly. Specifically, the rotation speed of the motor may be lower than a predetermined rotation speed, or the rotation timing may be shifted. Further, the belt that has been placed at a low temperature is hardened and may not rotate normally, or in the worst case, a trouble such as breakage of the belt may occur.

In some cases, the bill storage device is placed in a high-temperature environment. In general, when the motor is stopped, current is not allowed to flow inside the motor.However, in order to make the motor drive smoothly, a slight current should be supplied even when the motor is stopped. There is also. If a current is flowing when the motor is stopped, there is a danger that the motor will seize due to the heat generated by the current and the heat received from the outside and will not operate normally.

[0009] Such troubles lower the reliability of not only the bill storage device but also vending machines and currency exchange machines that store it. In order to solve such a problem, it is conceivable to provide a heater or a cooler inside a host machine such as a bill storage device or a vending machine. However, this is not preferable because it not only goes against downsizing of the device but also increases the cost. In addition, it is conceivable that the above-mentioned troubles can be solved by using components that operate normally even at a low temperature or a high temperature. However, the use of such special parts is not preferable because the cost of the apparatus increases.

The present invention has been made in order to solve such a problem, and presupposes the miniaturization and cost reduction of the apparatus, and performs accurate bill processing regardless of the temperature of the environment in which the apparatus is installed. It is an object of the present invention to provide a bill storage device that can be used.

[0011]

SUMMARY OF THE INVENTION In view of the above-mentioned object, a bill storage device according to a first aspect of the present invention has a storage room for storing bills and at least one of the inside and outside of the storage room. A motor for transporting bills, and when the motor is stopped, the motor generates heat by changing the current or resistance flowing inside the motor without driving the motor. .

According to a second aspect of the present invention, in the bill storage device of the first aspect, the heat generation amount of the motor is determined by a temperature detecting means for detecting at least one of the inside and the outside of the device. It changes when a temperature lower or higher than the temperature is detected.

According to a third aspect of the present invention, in the bill storage device according to the second aspect, the amount of heat generated by the motor changes according to the temperature detected by the temperature detecting means.

[0014] The invention described in claim 4 is based on claim 1,
In the bill storage device described in 2 or 3, the motor is a stepping motor.

[0015] Further, the invention described in claim 5 provides the invention according to claim 1,
The bill storage device according to 2, 3 or 4, wherein the motor is connected to a DC power supply in the range of 10 to 30 volts.

(2) Banknote recognition unit

FIGS. 4 and 5 show the bill discriminating section 1 respectively.
00 is a cross-sectional view as viewed from the side and top of FIG. The bill validator 100 temporarily detects the authenticity and type of the bill 1 by various sensors and temporarily suspends the bill 1 until the preparation for storing the bill 1 is completed when the bill is a genuine bill. And a unit 100b.

Detecting section 100a and temporary standby section 100b
Has a structure in which upper portions 100c and 100d serving as lids can be independently opened and closed. Therefore, inspection or repair is easy when a trouble occurs at the time of depositing the banknote 1 or during maintenance. A bill insertion slot 101 for receiving the bill 1 is provided on the entrance side of the bill recognition unit 100. An entrance sensor is provided inside the detection unit 100a.
102, optical identification sensors 103 and 104, magnetic identification sensor 105, pullout prevention lever sensor 106,
Each sensor of the termination sensor 107 is provided.

Each sensor 102, 103, 104, 10
The structures and functions of 5,106,107 are as follows. That is, the entrance sensor -102 is
0a are provided at positions where both ends in the width direction of the inserted bill 1 can be detected. As a result, when the narrow bill 1 is inserted, it is determined that the bill is a fake bill, and the fake bill is returned. The entrance sensor 102 has a function of transmitting a signal for operating the identification unit transport motor 108 and the electromagnetic clutch 109.

The entrance sensor 102 is a transmissive optical sensor, and is provided on a light emitting element provided above the bill insertion path of the detecting portion 100a (upper portion 100c of the detecting portion) and on a lower body side. And a light receiving element. The entrance sensor 102 detects the bill 1 received from the bill insertion slot 101.

The optical identification sensors 103 and 104 are provided further inside than the entrance sensor 102 when viewed from the bill insertion slot 101. 1 at almost the center of the detection unit 100a
And two sensors at each end of the detection unit 100a at the back of the position. The central light type identification sensor 103 provided at the center is an infrared sensor using infrared rays. The side optical identification sensor 104 provided on the side is a visible light sensor using visible light.

Any of the optical identification sensors 103 and 104
Is a transmission type sensor similar to the entrance sensor 102, and includes a light emitting element and a light receiving element arranged on the upper side 100c serving as a lid and the lower side serving as a main body. In this way, two types of light, infrared and visible light, are used.
For the following reasons. When light of different wavelengths is used, the waveform pattern is different. Therefore, the authenticity and type of the banknote 1 can be double-checked. Therefore, bills can be accurately identified.

The magnetic identification sensor 105 is connected to the detecting unit 10.
On the lower side of Oa, when viewed from the top of the apparatus, two are provided at positions substantially horizontal to the central light type identification sensor-103. The magnetic identification sensor 105 is a sensor that reads the magnetic pattern of the bill 1 passing therethrough. The magnetic identification sensor 105 reads a magnetic pattern from a magnetic material printed on a bill passing over the sensor, and identifies the authenticity and type of the bill 1. Thus, three optical identification sensors 103 and 104 and two magnetic sensors 10
5, the type and authenticity of the banknote 1 are accurately identified.

The pull-out prevention lever sensor 106 is a light-blocking type sensor for detecting the presence or absence of the bill 1, and is provided at the upper part 100c of the detection unit. When the bill 1 gets on the pull-out prevention lever 112, the pull-out prevention lever sensor-1
The pull-out prevention lever 112, which has blocked the light of No. 06, descends and comes off the position where the pull-out prevention lever sensor 106 was blocked. Thereafter, when the trailing end of the bill 1 passes through the pull-out prevention lever 112, the lever 112 rises and shuts off the pull-out prevention lever sensor 106 again. As a result, the pullout prevention lever sensor 106
Turns off. Thus, the pull-out prevention lever 112
The standing up of the banknotes prevents the banknotes from being extracted.

The trailing end sensor 107 is a transmission type optical sensor. When the trailing end of the bill 1 passes through the trailing end sensor 107, the transporting motor 113 stops and the transport belt 113 stops. I do. Therefore, banknote 1
Will wait in the temporary standby unit 100b. This is to prevent the bill 1 from being transported until the bill transport unit 200 and the bill storage unit 300 are ready for deposit. Note that the terminal sensor 107 turns off the electromagnetic clutch 109 when detecting the terminal of the bill 1. Therefore, when the banknote 1 is waiting in the temporary standby unit 100b,
Even if the next deposit is made from the bill insertion slot 101, the transport belt 114 is not driven. Also, this terminal sensor 107
Is composed of a light-emitting element and a light-receiving element arranged above and below the detection unit 100a, like other transmission-type optical sensors.

On the main body side below the detection unit 100a,
There are provided two conveyor belts 114 which are stretched on rollers 115 and 116, respectively. Six rollers 117 are provided on the upper side of the detection unit 100a at a total of six positions, which are opposed to the rollers 115 and 116 and the position opposed to each magnetic identification sensor 105. I have. When the bill 1 is driven in the depositing direction by the transport belt 114, the roller 117 is rotatable following the movement of the bill 1.

The roller-116 is connected to the shaft 118, and when the discriminating section transport motor 108 rotates, the electromagnetic clutch 1 is rotated.
When 09 is turned on, the output pulley 119 and the belt 12
0, rotatable via a clutch pulley 121, a gear 122, a gear 123 and a gear 124. Then, the rotation of the roller-116 causes the conveyance belt 114 to rotate.
Can be rotated in the depositing or dispensing direction.

It should be noted that the identification section transport motor 108 is a motor that rotates at a constant speed. As described above, the banknote recognition unit 10
0 is provided with an identification unit transport motor 108 as a motor independent of a stepping motor 700 described later. Therefore, even in the case of continuous deposit, the next bill 1 can be inserted to the temporary standby unit 100b in parallel with the deposit operation of the previously inserted bill 1. Therefore, banknote 1
Can be performed quickly.

Under the temporary standby section 100b, a roller is provided.
There are provided two conveyor belts 113 which are stretched over the roller 125 and the roller-126. Also, the temporary standby unit 100
Above b, there are provided two conveyor belts 130 which are stretched over the rollers 127, 128 and 129. Banknote 1 is transported by two transport belts 113 and two transport belts 130
And can be transported. Conveyor belt 11
3 is an output pulley 119, an output pulley 131, a belt 1
32, a drive roller-133 and a roller-126 are connected to the identification unit transport motor 108, and can be rotated in the deposit direction.

(3) Banknote transport unit

Next, the structure of the bill transporting section 200 will be described. FIGS. 6, 7 and 8 are a perspective view, a cross-sectional view as viewed from the side, and a cross-sectional view as viewed from a direction opposite to the bill insertion slot 101 when the transport path door 201 of the bill transport unit 200 is opened. The two conveyor belts 202 are each provided with two rollers 203, 2 installed inside the conveyor path door unit 201.
04, 205, 206, 207, and 208. The roller 203 is driven by rotation from a stepping motor 700 shown in FIG. 8 via a gear (not shown).

The stepping motor 700 is a motor that can rotate in both forward and reverse directions according to a signal from the CPU 501 in the control section 500. That is, the stepping motor 70 depends on when the banknote 1 is deposited and withdrawn.
The rotation direction of 0 can be changed.

Therefore, the transport belt 202 can transport the banknote 1 in the banknote transport section 200 in both the up and down directions depending on the rotation direction of the roller 203 connected to the stepping motor 700. In this embodiment, the deposit operation and the dispensing operation of the banknote 1 are performed on the same transport path, thereby reducing the size of the entire banknote storage device.

The rotation speed of the stepping motor 700 is changed at the time of payment or at the time of rejection described later. That is, at the time of deposit, the stepping motor 700 is rotated so that the moving speed of the transport belt 202 of the banknote transport unit 200 is faster than the moving speed of the transport belt 113 of the temporary standby unit 100b. As a result, the deposited banknote 1 is smoothly fed into the banknote transport unit 200. The rotation speed of the stepping motor 700 is preferably 1 to 3 times, and particularly preferably 2 times, the rotation speed of the discrimination unit transport motor 108. At the time of deposit, the moving speeds of the conveyor belt 113 and the conveyor belt 202 may be the same if necessary.

On the other hand, at the time of the rejection processing, the moving speed of the conveyor belt 202 is made slower than the moving speed of the conveyor belt 113. That is, the stepping motor 70
0 is set to rotate at a lower speed than the rotation speed of the identification unit transport motor 108. The rotation speed of the stepping motor 700 is 0.2 rotation of the rotation speed of the identification unit transport motor 108.
To 0.9 times, particularly preferably 0.5 to 0.8. At the time of dispensing, the moving speed of the conveyor belt 202 may be higher than the moving speed of the conveyor belt 113. The structure of the above-described stepping motor 700 will be described later.

On the bill storage device main body side of the bill transport section 200, two transport belts 210, 211, 212, 21
3 and two rollers-214, 215, 216, 21

b, 300c.

The conveyor belts 210, 211, 21
2, 213 are not driven directly by the stepping motor 700, but are rotated following the drive of the conveyor belt 202. Thus, the number of transport motors can be reduced, and the transport path door unit 201 that can be opened and closed can have a simple structure.

An eject transport gate 226 is provided in the bill transport section 200 at a position facing the bill transport port of the eject / reject section 400. The ejection transport gate 226 is provided for each of the stackers 300a and 300a.

5 (275) are the respective rollers -246 (276) and 247
(277) and 248 (278). The belt 245 (275) is driven following the stepping motor 700 shown in FIG.

The transport belt 202 and the transport belt 211 (2
The bill 1 conveyed by the drive of 12) is moved from the 1,000 yen conveyance gate 231 (261) to the stacker 300a (3).
00b), it first contacts the belt 244 (274). Then, the banknote 1 is driven by the belt 244 (274), and the stacker 300a (300
Head to b). Next, the central part of the front end of the bill 1 is the belt 2
44 (274) and Roller-249 (279). At this time, at the same time, both ends of the 1,000-yen bill contact each belt 245 (275).
(275). Therefore, the entire leading end of the bill 1 is driven smoothly by the belt and is smoothly carried into the 1000-yen bill stacker 300a (300b).

Each belt 244 (274), 245
(275) is changed by changing the ratio of gears meshing with the stepping motor 700 or the diameter of the pulley, or by driving the motor with a separate motor.
It is also possible to drive at a higher speed than in 2). Thereby, when the banknote 1 is transported from the 1,000 yen transport gate 231 (261) to the 1,000 yen bill stacker 300a (300b),
The bill 1 can be conveyed so as to be forcibly pulled.

The 10,000-yen transfer gate 291 has a shape consisting of only the center claw, and the 1,000-yen transfer gate 231 is provided.
It has the same structure as the back side of the tab 231a (261a) at the center of (261). Therefore, 10,000 yen bill 1
The bill 1 is carried into the 10,000-yen bill stacker 300c while being driven by the belt at the center of the leading end of the bill 1.

In the case of the 10,000 yen transfer gate 291, as in the case of the 1,000 yen transfer gate 231 (261), by changing the ratio of the gear meshing with the stepping motor 700, etc.
It is possible to carry out conveyance at a higher speed than the conveyance belt 213. Hereinafter, the numbers of the members of the 5,000-yen transfer gate 261 will not be written in parentheses after the corresponding numbers of the members of the 5,000-yen transfer gate 231.

As described above, each of the transport gates 231 and 26
By providing a belt or the like on the back side of the bills 1 and 291, the bills 1
Jams are less likely to occur even on the transport path that bends into the sections 0a, 300b, and 300c. One of the methods for preventing the jam is to prevent the transport path of the banknote 1 from being sharply bent. However, this increases the size of the bill storage device. For this reason, in this embodiment, the size of the apparatus is reduced by making the transport path of the banknotes 1 substantially perpendicular and utilizing rollers and the like effectively.

The bill transporting section 200 includes a transport path sensor-255 shown in FIG. 8 and a transport path door sensor-256 shown in FIG.
Is provided. The transport path sensor-255 is a reflection type optical sensor. The sensor-255 can detect light reflected from the surface of the banknote 1 when light emitted from the transport path sensor-255 is reflected. When the bill 1 is present at the position of the transport path sensor-255, a signal is sent to the control unit 500 to perform operations such as opening and closing the gate.

The transport path door sensor -256 is a contact type sensor, and when the transport path door 201 is opened, the contact is released and a signal is sent to the control section 500. Upon receiving the signal, the CPU 501 sends the signal to the transport belt 20.
The operation such as 2 is not performed. Transport path door 2
This is because safety is ensured by preventing the transport belt 202 and the like from being driven during removal of the banknote 1 that has caused a jam by opening 01, inspection of the apparatus, and the like.

(4) Banknote storage unit

Next, the structure of the stacker constituting the bill storage unit 300 will be described. The 1000-yen bill stacker 300a, the 5,000-yen bill stacker 300b, and the 10,000-yen bill stacker 300c have the same structure except that they have different capacities. Therefore, each stacker 300a, 300b, 3
The structure and function of the 1000-yen bill stacker 300a (hereinafter, referred to as “stacker” unless otherwise specified) 300a will be described.

FIG. 10 is a perspective view of a stacker 300a constituting the bill storage unit 300. Stacker-300a
Of the stack entrance upper roller 30
2 and a stack entrance lower roller 303 are provided.
Two rollers 302 and 303 are provided at positions facing each other. In addition, these rollers
302 and 303 are provided in the width direction of the banknote 1 at intervals smaller than the banknote 1. Roller under stack entrance
A transport belt is not wound around 303, and a transport belt 304 is wound around a roller 302 above the stack entrance.

The upper roller 302 at the entrance of the stack is
5, and is connected to the gear 306. Gear 306
Is a stepping motor 7 shown in FIG.
The rotation of 00 makes it possible to rotate forward and backward. Therefore, the banknote 1 is sandwiched between the transport belt 304 and the lower roller 303 of the stack entrance, and is transported inside or outside the stacker 300a.

A bill entry port 301 is provided with a stack entry sensor 307 for detecting passage of the bill 1.
1 are provided at positions facing each other. The stack entrance sensor 307 is a transmission type optical sensor, and includes a light emitting element and a light receiving element. Two sets of stack entry sensors 307 composed of both such elements are arranged with a width smaller than that of the banknote 1. A light-emitting element 307 b of the stack entrance sensor 307 (hereinafter, referred to as “stack entrance lower sensor”) 307 b is provided on the lower surface of the bill conveyance port 301. The light receiving element of the same sensor-307
The “stack entrance upper sensor” 307a is provided on the upper surface.

The bill 1 is connected to these sensors 307a,
If it exists between 07b, the light is blocked and the presence of the bill 1 can be detected. The stack entrance sensor 307 has a function of measuring the length of the bill 1 and the amount of light transmitted through the bill 1 when the bill 1 passes.

FIG. 11 shows a stack entrance sensor 307.
FIG. 3 is an enlarged view of the bill transfer port 301 as viewed from a side surface thereof. The stack entrance sensors 307a and 307b are covered by sensor covers 308a and 308b whose opposing flat portions are horizontal with the upper and lower surfaces of the bill conveyance port 301. If the sensor cover 308 is contaminated by dirt on the banknote 1, accurate identification of the banknote 1 becomes impossible.

Therefore, it is necessary to clean dirt brought in by the banknote 1. Although it is possible to provide a special cleaning mechanism, in order to avoid a complicated structure, the bill storage device is provided with a self-cleaning sensor cover 308a, 308b by another bill 1 itself. ing.

Specifically, the upper and lower sensor covers 308
By setting the gap between a and 308b to an appropriate distance,
Self-cleaning is realized. The bill 1 is always in contact with the lower sensor-cover 308b, but is frequently but not always in contact with the upper sensor-cover 308a. That is, if the lower sensor-cover 308b is more easily contaminated and the paper sensor 1 is narrow enough to always contact the upper sensor-cover 308a,
This is because a jam is likely to occur. The distance between the sensors and the covers 308a and 308b is 2.0 to 3.0 mm.
Is appropriate, and preferably 2.3 to 2.7 mm.
A further optimal width is between 2.4 and 2.5 mm.

At the top of the stacker 300a, a transport mechanism 309 for transporting the banknote 1 into and out of the stacker 300a.
Has been fixed.

FIG. 12 is a perspective view of the stacker 300a with the transport mechanism 309 removed. Behind the lower roller 303 of the stack entrance, there are three separating rollers-3.
10 are provided. When the banknote 1 is deposited into the stacker 300a, the roller 30 on the stack entrance is used.
2 and each separation roller-310 are driven in the depositing direction.
The lower roller 303 at the entrance of the stack rotates in the depositing direction when the bill 1 is conveyed. Thereby, the banknote 1 is transported inside the stacker 300a.

When the banknote 1 is carried out from the inside of the stacker 300a, the upper roller 302 of the stack is rotated in the dispensing direction by the driving of the stepping motor 700. Therefore, the roller 30 on the stack entrance
The conveyor belt 304 wound around 2 rotates in the dispensing direction. At this time, the separation roller-310 cannot be rotated in the dispensing direction. Specifically, the separation roller 31
The gear 319 connected to the gear 0 is provided with a one-way clutch that transmits drive only when rotating in the depositing direction.

The reason why the separation roller-310 cannot be rotated in the dispensing direction is as follows. When the banknotes 1 stored in the stacker 300a are carried out to the outside, two or more banknotes are separated together in a roller.
It may move along the roller surface of 310. At this time, when the separation roller-310 rotates in the dispensing direction, 2
This is because there is a risk that the second and subsequent bills will also be transported to the bill transport port 301 and double feed will occur.

A roller guide 311 is provided on the side of the separation roller-310 in the bill storage direction along the roller surface. FIG. 13 is an enlarged view of a part of the inside of the stacker 300a provided with the roller guide 311.
One end of the roller guide 311 is screwed to the outer wall of the stacker 300a so as to be able to contact and separate from the separation roller-310.

When the banknote 1 is carried out of the stacker 300a, the stored banknote 1 is driven by the conveyor belt 304 and a conveyor belt 312 described later to separate the roller guide 311 into a separate roller. Push in the direction of 310. The pressed roller guide 311 comes into contact with the roller surface of the separation roller-310. Therefore, the banknote 1 to be carried out is prevented from breaking downward from the separation roller-310 to cause a jam.

The height of the roller guide 311 can be adjusted in the vertical direction by adjusting a fixed screw (not shown). Further, depending on the length of the adjusting screw 313 to be screwed, the roller guide 3
11 and the separation roller-310 can be adjusted. Specifically, when the adjustment screw 313 is screwed in, the low
The upper end of the roller guide 311 approaches the separation roller-310. On the other hand, when the adjusting screw 313 is loosened, the upper end of the roller guide 311 separates from the separation roller-310. Thus, the height of the roller guide 311 and the distance between the separation roller 310 and the separation roller 310 can be adjusted while observing a situation where a double feed or a jam occurs during the dispensing operation.

FIG. 14 is a side view of the stacker 300a. FIG. 15 is a plan view of the stacker 300a as viewed from above the bill storage device. The transport mechanism 309 includes two transport belts 304 and 312 each. Each of the two conveyor belts 304 and 312
The belt is exposed on the lower surface of the transport mechanism 309.

The two conveyor belts 304 are stretched between the upper roller 302 and the roller 314 at the entrance of the stack.
Two transport belts 312 are provided between the transport belts 304 and stretched over three rollers 315, 316, and 317, respectively. Further, the gear 306 and the gear 319 are engaged with each other as shown in FIG. The gear 319 is rotatable in forward and reverse directions when driven by the stepping motor 700.

Outside the separation roller 310, two friction rollers 320 having a smaller diameter than the separation roller 310 are provided so as to be in contact with the conveyor belt 304. The friction roller 320 is a roller that rotates by receiving the driving of the conveyor belt 304 when the banknote 1 is dispensed, and is a roller fixed disk 321 provided outside the separation roller 310. It is rotatably fixed to. Further, the roller fixing disk 321 is provided rotatably about a shaft 318 which is coaxial with the separation roller-310.

Further, as shown in FIG.
The engagement fulcrum 322 on the stacker 21 and the stacker 300a are connected by a spring 323, and the friction roller 320 is urged upward. Therefore, the friction roller 320 contacts the conveyor belt 304 at a constant pressure within the rotation range. By providing the friction roller 320, the following effects can be obtained.

That is, in the dispensing operation of the banknotes 1, the banknotes 1 protruding in the direction of the separation roller-310 can be easily returned to the inside of the stacker 300a by an orderly operation described later. In addition, the bill 1 whose tip is broken
Is dispensed, the friction roller 320 can correct the tip of the bill 1 for dispensing. Further, even if a plurality of banknotes 1 enter between the friction roller 320 and the transport belt 304, the pressure applied to the banknotes 1 is constant, so that unnecessary pressure is not applied to the banknotes 1. For this reason, troubles such as double feeding and jam can be prevented.

FIG. 16 shows a state in which the banknote 1 is
FIG. 5 is a diagram showing a state when the paper is carried out, as viewed from a direction of a bill conveyance port 301. The upper surface of the banknote 1 includes a transport belt 304 wound around the upper roller 302 and a roller 317.
Is in contact with the transport belt 312 wound around. The lower surface of the bill 1 is in contact with the separation roller 310 and the friction roller 320.

The transport belts 304 and 312 are arranged below the upper surface of the roller of the separation roller-310. Therefore, at the time of withdrawal, the banknote 1
As shown in FIG. 6, the sheet is unloaded from the stacker 300a in the form of a waveform.

FIG. 17 shows the internal structure of the stacker 300a as viewed from the direction of the bill transfer port 301. Stacker-3
00a, the banknotes 1 are loaded and the stacker
A loading plate (hereinafter, referred to as a "pusher plate") 325 that can move up and down inside 300a is provided.
A plate hook 346 for hooking and fixing the pusher plate 325 is provided at the bottom of the stacker 300a. The usage status of the plate hook 346 will be described later.

FIG. 18 is a diagram showing the pusher plate 325 and its driving section extracted from FIG. As shown in the figure, a plate connecting portion 325c, which is a part of the pusher plate 325, is connected to a stacker-3 via an elastic body (hereinafter, referred to as a "pusher spring") 326.
The side plate 327 is fixed to the side plate 00a. The pusher spring 326 is bent in an inverted U-shape so as to contact a groove provided along the circumference of a disk 328 fixed to the stacker 300a. The pusher spring 326 is connected to the stacker 300a so as to urge the pusher plate 325 upward.

The pusher plate 325 is a pusher plate.
Fixed pusher pre-connected to spring 326
325a and a movable pusher plate 325b located on the fixed pressure plate 325a and capable of swinging the bill 1 in the width direction. Below the fixed pusher plate 325a, a shaft 329 is fixed in the width direction of the banknote 1, as shown in FIG. Above the shaft 329, there is provided a shaft 330 extending in the longitudinal direction of the fixed pusher plate 325a. The movable pusher plate 325b is connected to the shaft 330 via a connection plate 331 fixed to the plate 325b. The connecting plate 331 is rotatable about a shaft 330.

FIG. 19 shows a movable pusher plate 32.
It is a figure showing rocking operation of 5b. (A) is a diagram showing a state in which the plate surface of the movable pusher plate 325b is parallel to the fixed pusher plate 325a.
When the thickness a at the right end and the thickness b at the left end of the stacked banknotes 1 are almost equal to each other, as shown in FIG.
The plate surface of the plate 325b is in a horizontal state.

However, the thickness of the stacked banknotes 1 is not always constant. (B) is a diagram showing a state in which the thickness b at the left end of the stacked banknotes 1 is thicker than the thickness a at the right end. As shown in the drawing, when the uppermost banknote 1 of the banknote 1 comes into contact with the transport belts 304 and 312, the connecting plate 331 moves
Rotate in the opposite direction to the 30 clock. As a result, the uppermost banknote 1 can contact the transport belts 304 and 312 in a horizontal state.

FIG. 10C is a view showing a state where the thickness b at the left end of the stacked banknotes 1 is thinner than the thickness a at the right end. As shown, when the uppermost banknote 1 of the banknote 1 comes into contact with the transport belts 304 and 312, the connecting plate 331 rotates clockwise on the shaft 330. As a result, similarly to (B), the top banknote 1 is in a horizontal state and the transport belts 304,
312.

As described above, the movable pusher plate 3
Even if the thickness of the banknotes 1 stacked on the banknotes 25b is not uniform in the width direction of the banknotes 1, it is possible to contact the transport belts 304 and 312 on the stacker 300a with uniform pressure. Therefore, it is possible to prevent the bill 1 from being bent and dispensed, thereby preventing a jam. Even if the fixed pusher plate 325a and the transport belts 304 and 312 are not strictly parallel, a uniform pressure is applied to the banknote 1.

Therefore, the manufacturing cost can be reduced. It should be noted that, even if the movable pusher plate 325b is rotated left or right, the end portion thereof comes into contact with the fixed pusher plate 325a, so that the movable range does not become larger than necessary. . Therefore, there is no danger that the bill 1 on the movable pusher plate 325b will shift in the width direction.

As shown in FIG. 14, the stacker 30
0a has an arm portion (hereinafter referred to as a "stack arm").
332). Stack arm 33
2 has two elongated pre-presses as shown in FIG.
The interval between the two plates is smaller than the width of the banknote 1 and wider than the width of the transport mechanism 309. The stack arm 332 is provided at the lower portion of the stacker 300a.
3 and can be moved up and down by the rotation of the lift motor 333.

The stack arm 332 holds the bills 1 loaded on the pusher plate 325 in the payment standby state.
Presses the upper surface of the banknote 1 at the top of the
It stops at a predetermined position below 1. This is to prevent the bills 1 deposited in the stacker 300a from hitting the bills 1 already loaded on the pusher plate 325.

FIG. 20 is a side view of the stacker 300a immediately before unloading the banknote 1 from the stacker 300a.
When the bill 1 is dispensed, the stack arm 332 rises toward the transport mechanism 309. The pusher plate 325, as described with reference to FIG.
It is urged upward by the elastic force of the spring 326.

Therefore, when the stack arm 332 rises, the pusher plate 325 makes the upper surface of the uppermost banknote 1 of the banknotes 1 stacked thereon contact the lower surface of the stack arm 332. Ascends in a state where it is not Then, the stack arm 332 is connected to the transport belts 304 and 31.
When the paper money is moved above the belt surface of No. 2, the pusher plate 325 transports the top bill 1 to the transport belts 304 and 3.
12 and stop. The stack arm 33
The up-down movement mechanism 2 will be described later.

A stopper member is provided on the side of the stacker 300a opposite to the bill transfer port 301 for driving the transfer belts 304 and 312 in the opposite direction to the dispensing after the dispensing, that is, for holding down the leading end of the bill 1 during the so-called orderly operation. (Hereinafter referred to as “end stopper”) 334 is provided. The end stopper-334 includes a vertical portion 334a parallel to the vertical wall surface opposite to the bill transfer port 301, a pressing portion 334b bent at a right angle near the height of the bill transfer port 301 of the vertical portion 334a, and a pressing portion thereof. 334b upward angle α
(Α is an acute angle). Note that the angle α of the inclined portion 334c is
Is preferably in the range of 25 to 45 degrees, and is 35 degrees in this embodiment.

The vertical portion 334a of the end stopper 334
Is connected to the stacker 300a via a spring 335. FIG. 21 is a diagram showing the end stopper 334 and its peripheral portion. The spring 335 is provided so as to bias the end stopper 334 downward. In the deposit standby state shown in (A), the end stopper 334 is separated from the topmost banknote 1 of the banknotes 1 placed on the pusher plate 325.

On the other hand, at the time of dispensing shown in (B), the pusher plate 325 rises as the stack arm 332 moves above the conveyor belts 304 and 312. As a result, the top bill 1 of the bills 1 stacked on the pusher plate 325 is moved to the end stopper 33.
4 is slightly lifted, and the conveyor belts 304, 31
Touch 2 As shown in the figure, the end stopper 334 has a function of holding down the uppermost banknote 1 downward by a distance D slightly increased from the deposit state of (A).

For this reason, in the orderly operation immediately after dispensing the banknotes 1, the topmost banknotes 1 of the banknotes 1 loaded on the pusher plate 325 are driven by the transport belts 304 and 312 and bent. There is a low risk of spilling or sneaking into other banknotes 1 stacked below. Further, the tip of the end stopper-334 is provided with an inclined portion 334c.
Therefore, even if the banknote 1 moves in a direction to be placed on the end stopper 334 when the banknote 1 is deposited, the banknote 1 is surely directed downward under the end stopper 334. In this way, a normal deposit operation can be performed.

FIG. 22 shows the stacker 300 shown in FIG.
FIG. 3A is a diagram when viewed from a direction opposite to a bill conveyance port 301.
FIG. 23 shows the stacker 300a shown in FIG.
It is the figure seen from the direction opposite to the bill conveyance port 301. A stack arm driving chamber 336 storing a lift motor 333 for driving the stack arm 332 is provided on the back side (the right side in FIG. 22) of the stacker 300a. The lift motor 333 is fixed to a lower portion of the stack arm driving chamber 336.

As shown in FIG. 22, the stack arm 332 is made up of two plates to form a stack arm driving chamber 336.
It has a shape that protrudes into the protruding part,
The left and right sides have an elongated void portion 337 that is rounded.
A rotating arm 338 is attached to a motor shaft 333a of the lift motor 333. Rotating arm 33
A rotatable disk 339 is attached to the end of the motor shaft 8 in the direction opposite to the motor shaft 333a. Further, the disk 339 is provided in the gap 3 in the stack arm 332.
37, it is attached so as to be movable left and right.

Therefore, when the lift motor 333 rotates, the rotating arm 338 rotates, and the disc 339 rotates to move the gap 337 left and right. The rotation of the rotating arm 338 allows the stack arm 332 to move up and down.

The motor shaft 333 of the rotating arm 338
A cylindrical magnet 340 is provided at the end in the direction opposite to the direction a. One hole sensor-341 is fixed to the stacker 300a at a position where the disk 339 is almost at the bottom and at a position where it is at the top. The former and latter ball sensors-341 are a stack lift upper sensor-341a and a stack lift lower sensor-341 for stopping the stack arm 332 at predetermined upper and lower positions, respectively.
b.

As shown in FIG. 22, the lift motor 333
Is rotated, and the cylindrical magnet 340 is moved to the stack lift sensor.
When the signal overlaps with the signal 341b, a signal is sent to the CPU 501.
Then, the CPU 501 stops the lift motor 333. At this time, the stack arm 332 is connected to the bill transfer port 3
01 to a predetermined position below and pusher-press
325 is stopped. After such a state, the conveyor belts 304 and 312 are driven in the depositing direction, and a depositing operation is performed.

On the other hand, at the time of dispensing, as shown in FIG. 23, the lift motor 333 makes a half turn from the state shown in FIG. 22, so that the cylindrical magnet 340 overlaps the stack lift upper sensor-341a. Thereby, the CPU 501
Stops the lift motor 333. At this time, the stack arm 332 is stopped at a predetermined position above the belt surfaces of the transport belts 304 and 312. After such a state, the conveyor belts 304 and 312 are driven in the dispensing direction, and a dispensing operation is performed.

As described above, the lift motor 333 is always stopped every half rotation by the two stack lift sensors-341a and 341b. For this reason, the stack arc
The arm 332 can reciprocate at a predetermined vertical position.

A near-end sensor-342 for detecting that the bill 1 stored in the stacker 300a is almost empty and a near-end sensor for detecting that the bill 1 is almost full are provided on the inner wall of the stack arm driving chamber 336 of the stacker 300a. A near-full sensor-343 for detection is provided. These sensors
The fixed positions of 342 and 343 can be changed from outside the stacker 300a, but normally the position of the pusher plate 325 can be detected in a state where the stored bills 1 are almost empty or near full. Fixed in place.

The near-end sensor-342 and the near-full sensor-343 are cut-off sensors each having a gap at the center. When the detection plate 344 fixed to the pusher plate 325 enters this gap, light that has passed through the gap is cut off. By blocking the light, a signal is sent to the CPU 501. The detection plate 344 is a near-end sensor-342.
When the pusher plate 325 further rises after the detection, the near-end sensor 342 has a length sufficient to maintain the ON state. The same applies to the near-full sensor-343.

Further, when the near-end sensor-342 or the near-full sensor-343 is turned on, a mechanism is provided for relatively counting the number of banknotes that enter and exit the stacker 300a from the time of turning on. Specifically, after the near-end sensor-342 or the near-full sensor-343 is turned on, a count signal of the banknote 1 passing through the stack entrance sensor-307 is sent to the CPU 501. Then, the CPU 501 performs relative counting for relatively counting the increase and decrease of the banknote 1. Then, when the predetermined number of sheets stored in advance is reached, an end signal or a full signal is transmitted to notify that the banknote 1 stored in the stacker 300a is empty or full.

Therefore, when this bill storage device is connected to an external host computer, the storage state of the bills 1 can be quantitatively and temporally determined even at a location remote from the control device 509 of a host machine such as a vending machine. Can be grasped.

An unusable sensor-345 is provided below the near-full sensor-343. The unusable sensor-345 is fixed to a place where the pusher plate 325 is not turned on in the range of the vertical movement of the pusher plate 325 in the depositing and dispensing operations of the banknote 1.

[0120] Maintenance and inspection of this device or collection of bills,
When refilling, pusher plate 325 is stacked.
It is lowered to the bottom of 300a so that it can be fixed with a plate hook 346. At that time, the unusable sensor-345 is turned on. When the unusable sensor-345 is turned on, a pusher plate 325 is provided to the administrator.
Is recognized, and even if the power is turned on while the pusher plate 325 is fixed, the apparatus cannot be operated.

Therefore, when the present apparatus is operated, the plate hook 346 shown in FIG. 17 is detached from the pusher plate 325, and it is confirmed that the pusher plate 325 can be moved up and down. Then you can drive. As a result, the administrator can reduce the need for finishing operations such as replenishing and collecting bills while the apparatus is not operating.

FIG. 24 shows a stacker-3 during withdrawal.
It is a side view inside 00a. The transport mechanism 309 is provided with a mechanism for preventing double feeding when the stored bill 1 is detected by the stack entrance sensor 307. Hereinafter, such a mechanism will be described.

A stopper arm 348 rotatable about a shaft 347 is provided on the upper side of the stacker 300a opposite to the bill transfer port 301. The stopper arm 348 is connected to a brake solenoid (not shown) via a shaft 347. Therefore, when the brake solenoid is turned on by a signal from the control unit 500,
The stopper arm 348 rotates in the direction opposite to the clock in FIG.

The tip of the stopper arm 348 in the direction opposite to the shaft 347 can be rotated about a shaft 349 disposed in the direction of the bill feeding port 301 with respect to the shaft 347.
Connected to the tip 350 a of the drum 350. A brake member (for example, rubber) 351 having a large friction coefficient is attached to the tip 350 a of the brake arm 350. The brake member 351 is provided with an uneven groove in a direction perpendicular to the dispensing of the banknote 1.

Therefore, when the leading end of the uppermost banknote 1 of the stored banknotes 1 is detected by the stack entry sensor 307, the stopper arm 348 rotates, whereby the brake arm is rotated. The tip 350a of 350 descends. Then, the brake member 351 provided at the tip 350a is connected to the second banknote 1 immediately below the topmost banknote 1.
Hold the top of the

The transport mechanism 309 is provided with a roller arm 353 rotatable about a shaft 352 provided in the direction from the shaft 349 to the bill transfer port 301.
The tip 353b of the roller arm 353 is a breaker.
The position is located above a tip 350b of the drum 350 opposite to the tip 350a. Also, the tip 3 of the roller arm 353
A roller 354 that is rotatable in both the incoming and outgoing directions of the banknote 1 is provided at the leading end 353a opposite to the direction 53b.

When the brake arm 350 rotates clockwise in FIG. 24 and its tip 350b moves upward, the tip 353b of the roller arm 353 is lifted. At the same time, the roller arm 353 rotates counterclockwise in FIG. 24, and the roller-354 provided at the tip 353a pushes down the bill 1 to be dispensed.
As a result, the bill 1 to be dispensed and the conveyor belt 304,
312 is released. As a result, the second and subsequent bills 1 below the bill 1 to be dispensed are transported by the transport belt 304,
No driving is received in the dispensing direction by 312. for that reason,
Double feeding can be reduced as compared with a mechanism in which the brake member 351 merely presses the upper surface of the second bill 1.

When the bill 1 to be dispensed is detected by the stack entrance sensor 307, it is sandwiched between the stack entrance upper roller 302 and the stack entrance lower roller 303 wound around the transport belt 304. I have. Therefore, at this sandwiched position, payment is made by receiving the drive of the transport belt 304.
Since the roller-354 can rotate freely, the dispensing operation is smoothly performed.

Further, a tip 353 of the roller arm 353 is provided.
a is connected to the upper portion of the transport mechanism 309 by a spring 355 and is urged upward. Therefore, when the stopper arm 348 rotates clockwise, the roller
The arm 353 rotates clockwise about the shaft 352.
As a result, the roller-354 is transported by the transport belts 304,3.
It is housed above 12 etc.

By the way, each stacker 300a, 300
The structures and outer shapes of b and 300c are basically the same. However, the three types of banknotes 1 have the same width but different lengths. Specifically, the 1,000-yen bill is the shortest, and is longer by 5,000-yen bills and 10,000-yen bills by 5 mm. If the space for storing the banknotes 1 is not substantially the same as the size of the banknotes 1, the banknotes 1 cannot be stored in an organized state.

For example, each stacker 300a, 300
Assuming that the inside of b and 300c is a storage space adapted to the size of a 10,000-yen bill, 10,000-yen bills have no problem, but 1,000-yen bills and 5,000-yen bills have a lot of play because the ends are not aligned. Is stored.
Therefore, there is a risk that a trouble occurs in the dispensing operation. On the other hand, each of the stackers 300a, 300b, 300
If the inside of c is a storage space adapted to the size of a 1,000-yen bill or a 5,000-yen bill, a 10,000-yen bill is stored in a bent or bent state, which also causes a trouble.

Therefore, each of the stackers 300a, 300
Each of the stackers 300a, 300c is used to make the size of each of the stackers b, 300c suitable for the size of each banknote 1.
First, the internal space of the banknotes b and 300c is adjusted for a 10,000-yen bill. The end stopper 334 as an adjustment plate corresponding to the length of the end can be detachably mounted.

More specifically, a stacker 300a for 1,000 yen bills
Has an end stopper 334 having a thickness of 10 mm, and a stacker 300b for a 5,000-yen bill has an end stopper 334 having a thickness of 5 mm.

As described above, the size of each of the stackers 300a, 300b, and 300c is not changed for each type of banknote 1, and the contents of each of the stackers 300a, 300b, and 300c are determined only by attaching and detaching the end stoppers 334 having different thicknesses. The product can be changed. Therefore, each stacker 300
Components a, 300b, and 300c can be shared, and it is easy to respond to changes in the bills 1 to be handled. In particular, recently, the demand for using foreign bills such as US dollar bills has been increasing, and the present apparatus can quickly respond to such demands.

(5) Eject / reject part

Next, the structure of the eject / reject unit 400 will be described. 25 and 26 are a perspective view and a cross-sectional view of the eject / reject unit 400 as seen from the side, respectively. Eject / reject unit 40
0, as shown in FIG. 1, an eject unit 400a for storing genuine bills until all genuine bills are collectively dispensed and dispensing them all after all genuine bills are conveyed, and a counterfeit note, jam or double feed. And a reject unit 400b for storing only abnormal banknotes 2 (hereinafter, referred to as “foreign bills”) 2 such as the banknote 1 that caused the above.

The eject section 400a is arranged below the eject / reject section 400. On the other hand, the reject unit 400b is an eject / reject unit 400
Is located at the top. A bill dispensing port 401 from which the bill 1 is dispensed is provided in front of the eject portion 400a and outside the apparatus. In a direction opposite to the bill dispensing port 401, a bill transport port 402 for receiving the bill 1 from the bill transport unit 200 is provided. Bill transfer port 40
2 has an eject entrance sensor -40 capable of detecting the passage of a genuine bill or a foreign bill 2 conveyed from the bill conveyance unit 200.
3 are arranged.

The eject entrance sensor 403 is a transmission type optical sensor, and is provided with two light emitting elements 403b and two light receiving elements 403a at positions vertically opposite to the bill transport port 402. In FIG. 26, only one eject inlet sensor 403 can be seen at the top and bottom,
An eject inlet sensor 403 exists one at a time in the upper and lower directions in the direction opposite to the paper surface of FIG. The light emitting element 403b is provided below the bill transport port 402, and the light receiving element 403a is provided above the bill transport port 402. When the bill 1 exists between the light emitting element 403b and the light receiving element 403a, the ejection entrance sensor 403 sends a signal to notify the CPU 501 of the presence of the bill 1.

Further, an ejection entrance sensor 403
The upper and lower sensor covers 404a and 404 each have a flat contact surface with the bill 1 so that the dirt carried by the bill 1 can be self-cleaned when the other bill 1 is conveyed.
04b. Upper and lower sensor covers 404
The distance between a and 404b is suitably 2.0 to 3.0 mm, preferably 2.3 to 2.7 mm, similarly to the sensor cover 308 of the stack entrance sensor 307. A further optimal width is between 2.4 and 2.5 mm.

The bill 1 conveyed from the bill conveyer 200 is ejected by the lower roller-405 rotating in the dispensing direction.
The sheet is held by the upper eject roller 406 provided to be rotatable, and is conveyed into the eject / reject section 400. FIG. 27 is a diagram showing the eject lower roller-405 provided in the bill conveyance port 402 and its peripheral members. A circular support plate 407 larger than the diameter of the ejected lower roller-405 is provided on both side surfaces of the ejected lower roller-405.

Further, an impeller 408 having eight blades 408a made of soft urethane rubber is provided on both sides of the support plate 407.
Is provided. The impeller 408 is connected to the bill conveyance port 402.
At the same time as the banknote 1 transported from the
It has a role of holding down the banknote 1 being conveyed to a. The structure and function of the impeller 408 will be described later.

The eject lower roller-405 is connected to a stepping motor 700 provided at a lower part of the bill storage device via a gear (not shown). The eject roller 406 is rotatable but not connected to a drive source such as a motor. Therefore, banknote 1
Is held between an eject lower roller-405 driven by a stepping motor 700 and an eject upper roller 406 which rotates following the same roller-405, and is inserted into the eject / reject unit 400. Conveyed.

FIG. 28 shows the eject / reject unit 400 as viewed from the direction of the bill carrying port 402 when the bill 1 is carried. As shown in the drawing, the banknote 1 has a substantially U-shape due to the contact surface between the upper ejected roller 406 and the ejected lower roller-405. In addition, banknote 1
It is supported by the impeller 408 from the center to the end, and is held down by the lower surface of a rotary arm 485b to be described later.

Therefore, the banknote 1 has a gently wavy cross section as a whole, and the eject / reject unit 4
00 is transported. As a result, even if the used banknote 1 has wrinkles or folds, the eject unit 40
It is possible to prevent a trouble such as colliding with the banknote 1 already held in the ejecting section 400a without being bent or bent below 0a.

When the bill 1 conveyed from the bill conveyance port 402 is a foreign currency 2, the foreign currency 2 is rejected by the reject unit 400.
It is placed on the lift base 450 that has descended from b. The lift base 450 on which the different ticket 2 is placed rises again to the reject unit 400b and enters a standby state. on the other hand,
When the bill 1 conveyed from the bill conveyance port 402 is a genuine bill, the genuine bill is placed on a temporary holding plate 410 provided on a bill dispensing drive unit 420 fixed to a lower portion of the ejecting unit 400a. Is placed. At this time, the lift base 450
It remains in a state of waiting in the reject unit 400b.

As shown in FIG. 26, the lift base 450 is provided with an ejector arm 452 having a roller-451 at the tip. EJECTRO
When the lift base 450 is standing by at the reject unit 400b, the arm 452 is lowered below the lift base 450 as shown in FIG.

However, when the lift base 450 moves to the eject portion 400a, the roller-451 comes into contact with the banknote 1 placed on the temporary holding plate 410. Thus, the ejector arm 452 rotates counterclockwise about the shaft 453 in FIG. 26 and is housed inside the lift base 450. The ejector arm 452 has a role of narrowing the space in the direction of the bill dispensing port 401 so that the bill 1 conveyed from the bill transport port 402 is not rounded when a genuine bill is transported. I have. At the time of withdrawal, lift base 450
Does not hinder the banknote 1 from applying its own weight.

A guide arm 455 is connected to the ejector arm 452 by a shaft 454 substantially at the center of the arm 452 and extends horizontally in the direction of the bill transfer port 402. Are linked. In the guide arm 455, the lift base 450 is connected to the reject portion 400b.
Is in the horizontal state at substantially the same height as the bill transport port 402. However, lift base 4
When the unit 50 is moved down to the ejecting unit 400a, the guide arm 455 rotates about the shaft 454 to maintain the horizontal state by the storage operation of the ejector arm 452.

The guide arm 455 is provided to prevent the genuine bill from being wound up by the impeller 407 and causing a jam above the eject portion 400a when the genuine bill is conveyed to the eject portion 400a. Furthermore, there is also a purpose of preventing the genuine bill from colliding with the next banknote 1 by being rounded near the entrance of the eject section 400a. In this way, the genuine bill conveyed is normally held on the temporary holding plate 410 along the inclination of the ejector arm 452 while being held down by the guide arm 455 so as not to go upward. It is to be placed on.

FIGS. 29 and 30 are views showing the state of the temporary holding plate 410 and the bill dispensing drive unit 420 when the bill 1 is being conveyed to the ejecting unit 400a and immediately before dispensing, respectively. As shown in FIG. 29, the temporary holding plate 41
0 is provided on the upper part of the bill dispensing drive unit 420 fixed to the lower part of the eject unit 400a. When the banknote 1 is being conveyed to the ejecting section 400a, the temporary holding plate 410 is rotatable around two shafts 422 and 423, which are rotatable around a shaft 421. It is in a state of being lifted by the two rear rotating arms 424. Since the front rotating arm 422 is raised at a steeper angle than the rear rotating arm 424, the temporary holding plate 410 is inclined slightly higher in the direction of the bill outlet 401. It is in a state.

As described above, as the temporary holding plate 410 is inclined, the rear end of the banknote 1 placed on the temporary holding plate 410 is moved to the banknote transport opening 402 of the ejecting section 400a.
It can be aligned to the side. An impeller 408 rotates on the side of the banknote transport port 402, and the banknote 1 is pressed against the temporary holding plate 410 by the blade 408 a.

Therefore, the banknote 1 placed on the temporary holding plate 410 is compressed on the temporary holding plate 410 when the next banknote 1 is conveyed to the eject section 400a. Therefore, there is no danger that the banknote 1 placed on the temporary holding plate 410 and the banknote 1 newly transported to the ejecting unit 400a will collide with each other. further,
Since the temporary holding plate 410 is inclined upward in the direction of the bill dispensing port 401, the space in the direction of the bill dispensing port 401 is smaller than the space in the direction of the bill conveying port 402. For this reason, the bill 1 conveyed to the eject part 400a is
Troubles such as curling at the bill dispensing port 401 side can be prevented,
Normal ejection operation can be performed.

As shown in FIGS. 29 and 30, the temporary holding plate 410 has a bank
425a, 425b and the conveyor belt 426 can protrude slightly upward from the temporary holding plate 410.
And one large hole 412 is provided. As described above, the temporary holding plate 410 includes two front rotating arms 42.
It is lifted to the ejecting part 400a side by two and two rear turning arms 424. Therefore, except when dispensing, the roller-425 is placed over the temporary holding plate 410 from above.
a, 425b and the transport belt 426 do not protrude.

FIG. 30 is a diagram showing a temporary holding section 410 immediately before dispensing.
It is a figure which shows the state which fell to the banknote dispensing drive part 420. When an eject shutter solenoid 440 described later is turned on, the two front rotating arms 422 are turned on.
And two rear rotating arms 424 are respectively connected to shafts 421 and 421.
It rotates around 423 and falls down in the direction of the bill transport port 402. Thereby, the temporary holding plate 410 is lowered to the bill dispensing drive unit 420.

As shown in FIG. 26, the front rotating arm 42
The rear arm 2 and the rear rotating arm 424 are not fixed to the temporary holding plate 410. Rollers 422a and 424a are provided at portions contacting the temporary holding plate 410, respectively.
When the front rotating arm 422 and the rear rotating arm 424 fall down, the temporary holding plate 410 does not move in the direction of the bill transport port 402 but can smoothly descend vertically. ing. Therefore, the temporary holding plate 410 is not
The space of the ejecting section 400a can be smaller than that in the case of descending while moving in the direction of 02. Therefore, the size of the device can be reduced.

As shown in FIG. 30, when the temporary holding plate 410 descends and overlaps the bill dispensing drive unit 420, in addition to the rollers 425a and 425b and the transport belt 426, a bill detecting unit to be described later is used. Plate 427 also has a long hole 412
From the temporary holding plate 410. On the other hand, when withdrawing,
Since the banknote 1 on the temporary holding plate 410 is pushed by the lift base 450, the elevation of the banknote detection plate 427 is suppressed. Therefore, the bill detection plate 42
7 has a function of detecting whether or not the banknote 1 exists above. This function will be described later.

FIG. 31 is a perspective view showing the structure of the bill dispensing drive unit 420. The gear 430 is connected to a stepping motor 700 arranged below the bill storage device via a gear (not shown). The gear 430 is connected to a roller 432 via a shaft 431. Rollers 432 and 433 are wound around belt 434. The rollers 433, 435, 425a, and 425b are connected by a shaft 436.

The transport belt 426 is connected to the roller 43
5 and roller-437. Further, a roller 438 is provided at an approximate center of the transport belt 426 as an intermediate roller.
It is arranged as a line. Therefore, when the stepping motor 700 rotates, the roller-425 is rotated.
a, 425b and the conveyor belt 426 (hereinafter, appropriately,
(Referred to as “transport belt 426 or the like”) is rotatable.

On the other hand, the gear 430 is connected to the eject lower roller-405 via a belt (not shown).
Therefore, when the stepping motor 700 rotates in the dispensing direction, the rollers 425a and 425b and the transport belt 426 rotate in the dispensing direction, and the eject lower roller 405 also rotates in the dispensing direction. Has become.
Therefore, the banknote 1 to the eject / reject unit 400
And the transfer of the bill 1 to the bill dispensing port 401 can be performed by one motor. Therefore, it is possible to reduce the cost of the apparatus and to reduce the number of failures due to the simple structure.

As described above, the temporary holding plate 410
Does not descend to the banknote dispensing drive unit 420 until all the banknotes 1 to be dispensed are placed on the temporary holding plate 410. Therefore, even when the transport belt 426 or the like is rotating in the dispensing direction while the banknote 1 is placed on the temporary holding plate 410, the banknote 1 and the transport belt 426 or the like cannot contact.
For this reason, the bills 1 placed on the temporary holding plate 410 are not driven in the dispensing direction until immediately before dispensing.

FIG. 32 is a view showing a rotary arm 485 and a lift base 450 for separating the eject portion 400a and the reject portion 400b. The rotatable arm 485 is composed of two rotatable arms 485a disposed on the bill dispensing port 401 side and two rotatable arms 485b disposed on the bill transport port 402 side. Become. The pivotable arms 485a and 485b have a position where the lower limit of rotation is in the horizontal state (position B in the figure) shown in FIG. 32, and an upper limit rotation position approximately 90 degrees above the state (in the figure). (Position C). Rotating arm 485a, 4
Reference numeral 85b denotes a width smaller than the width of the banknote 1 and a lift base 45.
It is arranged at a position in contact with a rotating plate 456 provided one by one at each of the four corners of 0.

A pressing plate 488 for pressing the foreign bill 2 from above is placed on the rotary arm 485. The structure of the holding plate 488 will be described later. The four rotating plates 456 each have a lift base 45 on one side.
Each of the shafts 457 is connected to one shaft 457 (the remaining two shafts are not seen in FIG. 32). Further, as shown in FIG. 32, each rotating plate 456 is moved from the horizontal state to A
It is rotatable only in the direction A, and cannot be rotated in the direction opposite to A from the horizontal state by a stopper (not shown).

When the foreign bill 2 is transported from the bill transport port 402, the lift base 450 descends from the reject unit 400b to the eject unit 400a in accordance with a command from the CPU 501. At this time, the rotating plate 456 of the lift base 450, which is in contact with the rotating arm 485 holding the horizontal state, rotates in the direction A shown in FIG. As a result, the lift base 450 can descend to the eject portion 400a while avoiding the rotary arm 485.

The lift base 450 lowered to the eject section 400a moves up to the reject section 400b again when the foreign ticket 2 is placed. FIG. 33 shows a lift base 45.
The movement of the rotating arm 485a and the rotating plate 456 when the 0 moves upward to the reject portion 400b is determined by the movement of the bill outlet 40.
It is the figure seen from 1 and the left side. FIG. 33A shows a state in which the lift base 450 is in the eject section 400a. In this state, since the rotating arm 485a and the rotating plate 456 are not yet in contact with each other, both are maintained in a horizontal state.

When the lift base 450 rises and the rotary arm 485a comes into contact with the rotary plate 456 as shown in (B), the rotary plate 456 cannot rotate inside the lift base 450. Keep horizontal. On the other hand, a rotating arm 4
Since 85a can be rotated upward, it is pushed upward by the rotation plate 456. In this way, the lift base 450 moves to the reject unit 400b while rotating the rotary arm 485a upward.

The shaft 48 of the rotary arm 485a, 485b
6 is connected to a stopper (not shown),
The rotatable arms 485a and 485b do not rotate downward. Further, the stopper is connected to a spring and holds the rotating arm 485b horizontally. Therefore, as shown in FIG.
After the 50 has moved to the reject unit 400b, the pivotable arms 485a and 485b pivoted upward return to the original horizontal state by the restoring force of the spring.

FIG. 34 is a bottom view of the lift base 450 as viewed from below the bill storage device. Lift base 45
0 indicates two rollers-458a,
458b, one roller -459 substantially at the center, and two rollers -4 disposed close to the bill dispensing port 401 side.

Reference numerals 458b and 459 are arranged at positions facing the rollers 425a, 425b, and 438 of the bill dispensing drive unit 420, respectively.

In addition, the roller-460 disposed in close proximity
a and the roller-460b are the rollers of the banknote dispensing drive unit 420.
It is arranged at the position facing the -437. Therefore, at the time of dispensing, the lift base 450 is connected to the eject portion 4.
00a, the banknotes 1 to be dispensed are transferred to the upper and lower rollers 425a, 425b, 435, 437, 45.
8a, 458b, 459, 460a, and 460b.

FIG. 35 shows a lift base 450 immediately before dispensing.
And each roller-425a, 425 of the bill dispensing drive unit 420
b, 435, 437, 458a, 458b, 459, 4
It is a side view in the state where bill 1 was pinched by 60a and 460b. Each of the rollers -458a, 459, and 460a is connected to each of the shafts 461a, 462, and 463, respectively. In addition, in FIG. 35, although it is behind the banknote 1 and cannot be seen, as shown in FIG. 34, each roller-458b, 460
b is connected to each of the shafts 461b and 463, respectively.

Further, as shown in FIG.
Both ends of 61a, 461b, 462, and 463 are connected to the inside of the lift base 450 via two springs 464a, 464b, 465, and 466, respectively.
Therefore, even when the surface of the bill 1 to be dispensed is not flat in the dispensing direction, the bill 1 can be sent to the bill dispensing port 401 with a uniform pressure.

FIG. 36 shows a lift base 450 immediately before dispensing.
FIG. 2 is a diagram viewed from the direction of the bill dispensing port 401. Two rollers-458 provided at both ends of the lift base 450
a, 458b and the bill dispensing port 401 of the lift base 450
Rollers -460a, 46 provided close to the side
0b is shown. In addition, since the roller -449 is located behind the two rollers -460a and 460b,
It is omitted from FIG. 36 in order not to complicate the figure. As shown in the drawing, even when the banknotes 1 are in a non-uniform state from left to right as viewed from the banknote pay-out port 401, the banknotes 1 are clamped with a uniform pressure. Therefore, the bill 1 is inserted into the bill outlet 4
It is possible to carry straight to 01.

FIG. 37 is an enlarged view of the roller-458b as viewed from the bill outlet 401. As shown, both ends of the shaft 461b of the roller-458b are connected by separate springs 464b. Therefore, Roller-4
58b is tiltable with respect to the illustrated center line. Therefore, even if the banknote 1 has local irregularities, a uniform pressure can be applied. FIG. 37 shows only the roller-458b.
458a and 459 have the same structure.

FIG. 38 is a side view of the eject / reject unit 400 when the foreign currency 2 is transported from the bill transport unit 200. As shown, lift base 450
Has been moved to the ejection unit 400a. The foreign paper 2 already conveyed is placed on the rotary arm 485 with the pressing plate 488 placed on the upper part thereof. As described above, the lift base 450 can move below the rotary arm 485 by rotating the rotary plates 456 provided at the four corners.

However, the bill 2 and the holding plate 488, which are wider than the rotary arm 485, cannot move below the rotary arm 485 and remain in the eject portion 400b. If only the foreign currency 2 is placed on the rotary arm 485, the foreign currency 2 is separated from the rotary arm 485 by the folding habit of the foreign currency 2 and its weight. There is a danger of falling into the ejecting section 400a. Therefore, press plate 4
88 are disposed in the reject unit 400b. The pressing plate 488 also has a function of compressing the foreign bill 2 from above to store as many foreign bills 2 as possible in a narrow space.

FIG. 39 is a perspective view showing a state in which the holding plate 488 is removed from the wall surface of the eject / reject unit 400. FIGS. 40 and 41 show the holding plate 488 viewed from the top of the apparatus and the bill dispensing port 40, respectively.
It is the figure seen from 1 direction (direction of arrow A of FIG. 39).
As shown in FIGS. 39 to 41, the holding plate 488 includes

The lower ends of the grooves 490a and 490b are L-shaped, and the hooks 489a and 48
9b can be inserted. In addition, each groove 4
The lower ends of 90a and 490b are below the rotatable arm 485. Therefore, the holding plate 488, which can move up and down only above the rotary arm 485, does not fall out of the grooves 490a and 490b during operation of the apparatus.

Note that the hook 489a is connected to the holding plate 488.
The shape is such that it is on the same plane as. On the other hand, the hook 489b is shaped so as not to be on the same plane as the holding plate 488. The reason for this difference in shape is that
For the following reasons. As shown in FIG. 44, a reject full sensor 49 having a function of notifying that the foreign currency 2 is full is provided at the upper right of the illustrated eject / reject unit 400.

Numeral 1 is disposed on the back side of the space of FIG. When the number of foreign tickets 2 to be stored increases,
The hook 489b pushes up the adjusting screw 493 against the elastic force of the spring 492. When the adjusting screw 493 rises,
Along with this, the small arm 494 is raised. Then, when the stored bill 2 reaches a predetermined amount and the small arm 494 has a predetermined inclination, the reject full sensor-492 is turned on.

FIG. 42 is a diagram showing the state shown in FIG. 26 as viewed from the direction of the bill dispensing port 401. Lift base 45
Eject lift motor 47 which is a motor for driving 0
Reference numeral 1 denotes a lift base drive unit 470 provided on the back (right side in FIG. 42) of the eject / reject unit 400. The lift base 450 has a drive arm 450 a protruding from the lift base drive section 470.
A disc 472 is connected to a motor shaft 471a of the eject lift motor 471. Further, the disk 472
Is connected to a cam 474 via a rotating arm 473.

The rotating arm 473 is provided with a magnet 475 (not shown). Further, when the cam 474 comes to the substantially vertical upper part and the vertical lower part, one ball sensor-476 is provided at a position facing the magnet 475, respectively.
Has been fixed. One is an eject-lift-motor-on sensor-476a provided to stop the lift base 450 at the reject unit 400b. The other is an eject lift motor lower sensor-476b provided to stop the lift base 450 at the eject section 400a.

[0180] Both Hall sensors-476 have magnets 47
When it overlaps with 5, a signal is sent to the CPU 501. As a result, the eject lift motor 471 stops. Therefore, the eject lift motor 4
The reference numeral 71 stops in units of a half turn. According to FIG. 42, the lift base 450 is stopped at the reject unit 400b because the magnet 475 overlaps the eject lift motor upper sensor-476a.

FIG. 43 shows a state in which all the bills 1 to be dispensed on the temporary holding plate 410 have been placed or the foreign bill 2 has been lifted.
FIG. 9 is a view showing a state in which the lift base 450 has been lowered onto the temporary holding plate 410 when it is placed on the base 450; The rotating arm 473 has rotated half a turn from the state shown in FIG.
In this state, the cam 474 is disengaged from the drive arm 450a. Therefore, the banknote 1 placed on the temporary holding plate 410 is under the weight of the lift base 450.

FIG. 44 shows the state of FIG.
FIG. 1 is a diagram viewed from the left side of FIG. Even if the lift base 450 is lowered onto the temporary holding plate 410, at this stage, the temporary holding plate 410 has not yet been lowered toward the bill dispensing drive unit 420 below. In addition, the roller-4 of the bill dispensing drive unit 420
25a, 425b and the conveyor belt 426, when all the banknotes 1 to be dispensed have been conveyed to the eject unit 400a,
It is designed to stop. Further, as shown in FIG. 44, the front rotating arm 422 includes arms 441a and 44a.
It is connected to the eject shutter-solenoid 440 via 1b, 441c and 441d.

FIG. 45 is a view showing a state in which the lift base 450 is lowered to the temporary holding plate 410 side. When the lift base 450 descends on the temporary holding plate 410, the rotating arm 47 connected to the eject lift motor 471 is rotated.
The lift sensor (not shown) provided in 3 is turned on. As a result, the eject shutter-solenoid 440 is turned on.

When the eject shutter solenoid 440 is turned on, the front rotating arm 422 is turned on by each arm 44.
1a, 441b, 441c, and 441d are pulled down and fall. When the front rotating arm 422 falls, the rear rotating arm 424 also falls in the direction opposite to the bill dispensing port 401. As a result, the temporary holding plate 410 moves downward and overlaps the banknote dispensing drive unit 420. In addition, the eject shutter
The solenoid 440 is turned off immediately after being turned on.

A bent arm 442 having a bent shape is connected to a shaft 421 of the front rotating arm 422.
It turns in conjunction with the turning of the front turning arm 422. One ball sensor-443 is fixed to each of two positions where the bending arm 442 rotates and the magnet 445 stops. Both Hall sensors-443
Hall sensor fixed at a predetermined upper position
Reference numeral 443 denotes an eject shutter-upper sensor-443a for notifying that a shutter-413 described later has opened. The hole sensor-443 fixed at a predetermined lower position is an eject shutter lower sensor-443b for notifying that the shutter 413 has been closed.

As shown in FIGS. 44 and 45, the bill dispensing port 4 before the dispensing is located on the side of the bill dispensing port 401 of the temporary holding plate 410 and facing the bill dispensing port 401.
A shutter 413 having a function of closing the shutter 01 is provided. Further, the shutter-413 is connected to the temporary holding plate 41.
It is attached so as to operate integrally with 0. Accordingly, the bill dispensing port 401 can be opened and closed by the vertical movement of the temporary holding plate 410. By making the bill outlet 401 openable and closable by such a simple mechanism, it is not necessary to provide a special shutter mechanism. Therefore, it is possible to reduce the cost of the apparatus and the number of failures.

When the bending arm 442 rotates and the eject shutter upper sensor-443a is turned on, a signal indicating that the shutter-413 has been opened is sent from the sensor-443a to the CPU 501. Further, a lift base is provided from above the banknote 1 placed on the temporary holding plate 410.
Weight 450 For this reason, the magnet 428 fixed to the lower end of the bill detection plate 427 provided in the bill dispensing drive unit 420 overlaps with the bill presence / absence sensor-429 which is a hall sensor. After confirming that both the eject shutter upper sensor-443a and the bill presence / absence sensor-429 are on, the CPU 501
The stepping motor 700 is driven in the dispensing direction.

FIG. 46 shows the state of FIG.
It is the figure seen from the direction of 01. The lift base 450 is
It can be seen that the temporary holding plate 410 has been lowered to a position lower than the position shown in FIG. In this state, the cam 474 is separated from the drive arm 450a as in the state shown in FIG. Therefore, the banknote 1 placed on the temporary holding plate 410 has a lift base.
S 450 is under its own weight. Therefore, it is not necessary to provide a special pressurizing mechanism as compared with the case where pressure is applied to the banknote 1 from below to dispense it. Therefore, it is possible to reduce the cost of the apparatus and the number of failures.

FIG. 47 is a diagram showing a change in the operation of the bill detecting plate 427 while the bill 1 is being dispensed.
In the stage immediately before dispensing shown in (A), the bill detection plate 4
27 is a temporary holding plate 410 by the weight of the lift base 450.
The bill 1 is pressed downward by the bill 1 compressed. Therefore, the magnet 428 fixed to the lower end of the bill detection plate 427 is in a state (on state) in which the magnet 428 is overlapped with the bill presence / absence sensor 429 for detecting the presence or absence of the bill 1 to be dispensed.

However, as shown in (B), when the trailing end of the bill 1 is conveyed from the bill detection plate 427 to the bill outlet 401, the bill detection plate 427 rises,
The magnet 428 moves away from the banknote sensor 429 (off state). Then, the conveyance of the banknote 1 is stopped, and a part of the banknote 1 is held in a state of protruding from the banknote outlet 401. Therefore, since the bill 1 does not completely go out of the apparatus, a user such as a vending machine can easily receive the bill 1.

In addition, immediately before the bill dispensing port 401, FIG.
3 to FIG. 46, the ejection outlet sensor
444 are provided. This sensor-444 is a sensor for detecting whether or not the bill 1 has been removed. The eject outlet sensor 444 is a transmission-type optical sensor, and includes a pair of light-emitting and light-receiving elements. When the bill 1 enters between the light emitting element and the light receiving element, the light is blocked, whereby the presence of the bill 1 can be detected.

When the banknote 1 is pulled out from the banknote outlet 401, the eject outlet sensor 444 is turned off.
Then, a signal notifying that the banknote 1 does not exist is C
It is sent to PU501. As a result, the eject lift motor 471 rotates, and the lift base 450 rises to the reject unit 400b. Lift base 450
Is connected to the temporary storage plate 410 by a spring (not shown), so that the temporary storage plate 410 is lifted upward with the lift base 450 being raised. In this way, the eject / reject unit 400 returns to the state shown in FIG.

(6) Bill storage door

A bill storage door 600 is provided on a side surface of the bill storage unit 300 and the eject / reject unit 400 of the bill storage device. Bill storage door 600
Can be opened at the time of repair and inspection of the bill storage device and at the time of bill collection and replenishment.

FIGS. 48 and 49 show that the key portion 601 is
It is the perspective view which looked at the inside of the stacker 300a, and the enlarged view which looked at the door (it is hereafter called "banknote storage part door") 600 from the open side. The key unit 601 includes a door sensor 601a that detects opening and closing of the bill storage unit door 600,
And a locking unit 601b for locking the bill storage unit door 600.

The locking section 601b is connected to the bill storage section door 600.
And a hook 603 provided on the apparatus main body side. Plate 602
Has a shape that is three-dimensionally bent into a crank shape. Hereinafter, this plate is referred to as a "crank-type bracket". As shown, a magnet 606 that can be detected by the door sensor 601a is fixed to the crank-type bracket 602.

Further, a hook 603 provided on the main body of the apparatus.
Has a U-shape. Hereafter, this hook
"Thin hook metal fittings". 48A and 48B, in order to make the structure and operation of the locking portion 601b easy to understand, the thin hook fitting 603 is shown as floating, and a door sensor 601a described later is omitted. ing.

As shown in FIG. 49, the thin hook fitting 60
3 has a groove 603a. Then, at the time of locking, the thin hook fitting 603 is put on a plate 602a which is a part of the crank fitting 602. When the bill storage door 600 is opened, in FIG. 48B, the key 604 is inserted into the surface of the thin hook fitting 603 and rotated clockwise.

Then, the thin hook fitting 603 is
As shown in (B), the key rotates in the direction of arrow X about the key insertion port 603e. As a result, the tab portion 603b of the thin hook fitting 603 is moved to the plate 602a.
Out of the way. At the same time, the lower portion 603c of the thin hook fitting 603 pushes the crank-shaped fitting 602 in the direction of arrow Y. Therefore, the bill storage unit door 601 is a key-60.
By turning the number 4, it automatically opens outward.

The thin hook fitting 603 is connected to the stacker 300a via a spring 605. The spring 605 is connected to the fixed point 603d of the thin hook fitting 603 and the fixed point 300d of the stacker 300a. The thin hook fitting 603 is urged by the spring 605 to return to the locked state when the bill storage door 600 is opened and the key 604 is released.

Therefore, unless the key 604 is inserted again to release the locked state of the thin hook fitting 603, the bill storage door 600 cannot be closed. This is to avoid the risk of locking the key 604 while keeping it inside the apparatus.

As shown in FIG. 49, a door sensor 601a is provided above the thin hook fitting 603 as a door sensor.
A hall sensor (hereinafter referred to as a "banknote storage unit door sensor") is provided. At the time of locking, as shown in FIG. 49A, the bill storage unit door sensor 601a and the magnet 606 fixed to the crank-type bracket 602 overlap.
As a result, the CPU 501 is ready for operation of the apparatus.

On the other hand, as shown in FIGS. 49 (B) and 50, when unlocking, the bill storage door sensor 601a and the magnet 606 are separated. In addition, 602L in FIG. 50 is the position of the crank-type metal fitting 602 at the time of locking. As a result, the bill storage unit door sensor 601a is turned off.
The CPU 501 rotates the lift motor 333 to move the stack arm 332 upward, and then stops the operation of the entire apparatus.

The reason why the stack arm 332 is moved upward is to facilitate collection, replenishment or inspection of the banknote 1. And then,
The reason why the operation of the entire apparatus is stopped is that there is a risk of injury if the apparatus is operated during work such as collection of the banknote 1.

(7) Control unit

FIGS. 51 and 52 are block diagrams showing the relationship between the components of the bill storage device. Control unit 500
Is the identification unit 100, the bill transport unit 200, the bill storage unit 30
0, the exchange of signals with the eject / reject unit 400 and the external communication unit 508 enables accurate operation of the bill storage device.

The discriminating unit MPU 501a receives from the optical and magnetic sensors various signals of the length of the deposited banknote 1, the light transmission pattern and the magnetic pattern. Then, the identification unit MPU compares the stored data of the various bills of the 1,000-yen bill, the 5,000-yen bill and the 10,000-yen bill, and if any of the bills matches the authentic bill information, the identification unit MPU determines the predetermined bill. Perform the operation. On the other hand, if the data do not match, the banknote 1 is determined to be a counterfeit note and the bill 1 is returned.

The CPU 501 of the control unit 500 determines the presence of the banknote 1, the length of the banknote 1, the length of the banknote 1 from the optical and magnetic sensors in the banknote transport unit 200, banknote storage unit 300, and eject / reject unit 400. This is a part for receiving a signal such as a light transmission pattern. Then, the data is compared with the data recorded in the ROM 502, and if they match, a predetermined operation is performed. On the other hand, if they do not match, it is determined to be a counterfeit note, and a predetermined process such as a rejection process is performed.

The RAM (1) 503 stores in advance that a signal from the next sensor is received at a predetermined step. Therefore, when the bill 1 cannot go between a certain sensor and another sensor within a predetermined step range, it is determined that the bill 1 has jammed in the middle of the route. Also, the RAM (1) 50
3 includes a stacker 30 immediately after the deposit and withdrawal operations.
Data is also stored in which the number of steps for driving the uppermost banknote 0a in the direction opposite to the dispensing is 24.

The RAM (2) 504 stores, as backup data, the length of the bill 1 sent from each sensor, the number of data such as magnetic patterns and the number of errors, and the like. It is a part to put.

[0211] The power supply unit 507 is a power supply for the bill storage device, and uses a 24V DC power supply. Although not shown, a pulse generator (CPU 501) for pulsating DC is provided between the DC power supply and the stepping motor 700.
Is provided. When rotating the stepping motor 700, the direct current is pulsed through a pulse generator and then sent to the stepping motor 700. Therefore, when the stepping motor 700 is warmed at a low temperature, a current is allowed to flow through the stepping motor 700 in a DC state without operating the pulse generator. Since a 24V DC power supply is used as the power supply, it is safer than an AC 100V power supply even if a leak occurs. Further, since an external power supply is used, the weight of the apparatus can be reduced. Further, there is an advantage that the operation of the device is stabilized because the voltage is stable.

(8) Stepping motor

[0213] The driving sources of the bill storage device of the present invention are the identification unit transport motor 108 provided in the bill transport unit 100 and the stepping motor 700 provided in the lower part of the device. Therefore, from the bill validating section 100 to the bill transporting section 2
Conveyance of banknote 1 after being sent to 00 and stacker 30
The operation of transporting the banknote 1 from the inside of the banknote 0a to the banknote outlet 401 is performed using one stepping motor 700. For this reason, it is possible to perform the operation of depositing and identifying the next bill 1 in parallel with the operation of storing the bill 1 inside the stacker 300a or the like. Therefore, a short-time processing is possible when a plurality of banknotes 1 are deposited. In addition, the bill transport unit 200 and each stacker 300
a and the like, and inside each of the stackers 300a and the like, are transported by step driving by the stepping motor 700. For this reason, it is possible to switch between transport and stop and secure an accurate transport distance.

The rotation speed of the stepping motor 700 is 3
It is variable in the range of the pulse number of 00 to 1500 pps. Note that the range of the number of pulses is not limited to this range. The bill storage device in the present embodiment is
This range is adopted in consideration of the quick depositing / dispensing operation of the banknote 1 and the occurrence of errors such as jams. Also. The initial operation when the power of the apparatus is turned on is a stepping motor 7.
00 rotates in the forward and reverse directions, and the respective transport belts disposed inside the bill transport unit 200, the bill storage unit 300, and the like rotate. This is to confirm that there is no abnormality in the operation of the device.

When the stepping motor 700 is rotating, the temperature of the stepping motor 700 becomes high. Therefore, even if the temperature of the outside world falls in winter, there is little danger that the operation of the apparatus will be hindered. However, when the stepping motor 700 is stopped, the temperature inside the apparatus is close to the outside temperature, so that not only the operation of the stepping motor 700 but also the operation of other components such as the rollers and the conveyor belt are hindered. May add. For example, at normal temperature (around 20 ° C)
It is as if the operation is slower or freezes and does not operate.

In order to prevent such a trouble, a thermometer as a temperature detecting means is provided on the side wall of the stepping motor 700. When the temperature of the outside is reduced to 5 ° C. or less in the vicinity of the stepping motor 700, the current flowing to the stepping motor 700 is increased when the stepping motor 700 is stopped, so that the stepping motor 700 is operated. I'm making it fever. The heat value is such that the stepping motor 700 is maintained at about 5 ° C.

When the stepping motor 700 is rotating or when the temperature is 5 ° C. or higher, the heat is not generated. This is because power is wasted. By employing such a heat generation system, even when the motor is stopped for a long time, the risk of hindering the operation of the apparatus can be reduced.

(9) Payment operation

FIG. 53 shows a flowchart of the deposit operation. Hereinafter, the deposit operation of the bill storage device will be described in accordance with the flowchart.

First, the power supply unit 507 of the bill storage device is turned on to enter a payment standby state (step S1). In this state, first, the banknote 1 is inserted into the banknote insertion slot 101 of the banknote recognition unit 100, and a depositing operation is started (step S2).
Then, the entrance sensor -102 provided in the detection unit 100a of the banknote recognition unit 100 detects whether or not the banknote 1 has been inserted (step S3). In addition, since the width of the inserted bill 1 is smaller than the width of the regular bill 1, the entrance sensor
If it is not detected by 102, it remains in the original standby state.

When the entrance sensor 102 detects the bill 1, the electromagnetic clutch 109 in the bill discriminating section 100 is turned on, and the discriminating section transport motor 108 rotates in the depositing direction (step S4).

When the identification section transport motor 108 rotates in the deposit direction, the transport belt 114 of the detection section 100a and the transport belt 113 of the temporary standby section 100b rotate in the deposit direction. For this reason, the banknote 1 goes further inside while being held between the transport belt 114 and the six rollers 117.
Banknote 1 is composed of two magnetic identification sensors-105 and detection unit 1
While passing through the side optical identification sensor 104 and the central optical identification sensor 103 arranged at 00a, the length, the light transmission pattern and the magnetic pattern of the bill 1 are detected (step S5). ).

The trailing end of the bill 1 is the side optical identification sensor-1.
04, the identification unit transport motor 108 stops (step S6). Here, the identification unit MPU 501
a compares the identification data received from the magnetic identification sensor 105 and the optical identification sensors 103 and 104 with the data of various banknotes 1 stored in the identification unit MPU 501a in advance. It is determined whether the ticket is genuine (step S
7).

As a result, each of the detected identification data is 3
When the data does not match any data of the kind bill, the identification unit MPU501a determines that the deposited bill 1 is a fake bill. Then, the identification unit transport motor 108 is rotated in the direction opposite to the deposit (step S8). Thereby, banknote 1
Is transported to the bill insertion slot 101 by the transport belt 114 of the detection unit 100a.

When the rear end of the counterfeit note returned to the bill insertion slot 101 has passed through the central light identification sensor 103,
The identification unit transport motor 108 stops and enters a state of waiting for withdrawal of a counterfeit note (step S9). And the entrance sensor
The identification unit MPU501a that has received the signal from the CPU 102 determines whether the banknote 1 has been pulled out (step S1).
0). When the bill 1 is pulled out and the entrance sensor 102 no longer detects the bill 1, the bill storage device returns to a state of waiting for the next bill 1 to be deposited (step S11). on the other hand,
When the bill 1 is not pulled out, the identification unit MPU50
1a returns to step S9 and waits for the bill 1 to be pulled out.

The identification data of the inserted bill 1 is
If any of the bill data matches, the deposited bill 1 is determined to be genuine. Then, the identification unit transport motor 108 rotates again in the deposit direction (step S12),
The bill 1 advances to the temporary standby section 100b in response to the driving of the transport belts 114 and 113.

A pull-out preventing lever provided at the lower end of the pull-out preventing lever 112 of the detecting portion 100a has a rear end of the bill 1.
After passing through the sensor 106, the discrimination unit transport motor 1
08 stops, and the electromagnetic clutch 109 is turned off (step S13). Therefore, the banknote 1 stops at the temporary standby section 100b and the pull-out prevention lever 11
2 rises from below the detection unit 100a. As a result, thereafter, the bill 1 cannot be pulled out.

Next, the bill validating section 100 includes a control section 500
And sends a payment notification to the control unit 509 of a higher-level machine such as a vending machine via the external communication unit 508 (step S14). The banknote recognition unit 100 enters a state of waiting for a genuine bill confirmation signal from the control unit 500 that controls the banknote transport unit 200 (step S15).

On the other hand, the bill transport unit 200 and the control unit 500
After the power is turned on, the standby state is the same as the standby state of step S1 of the bill validator 100 (step S16). Then, the bill transport unit 200 and the control unit 500
When the genuine note signal is input from the bill validating section 100 in step S14, the genuine sheet determines whether the genuine note signal has been confirmed (step S17).

As a result, the control section 500 (specifically, C
When the PU 501) receives the genuine bill signal, it sends a signal to each of the transfer gate solenoids 232 and 262 of each of the stackers 300a and 300b according to the type of the bill 1. Then, the CPU 501 controls the 1000 yen transport gate 231 or 5
One of the 1,000 yen transfer gates 261 is opened and the stepping motor 700 is rotated (step S1).
8).

As a result, the transport belt 202 of the banknote transport section 200 is driven in the depositing direction, and the preparation for depositing is started. When the bill 1 is a 10,000-yen bill, the 10,000-yen transfer gate 291 is always open, so that the transfer gate solenoid is not turned on. Therefore, the stepping mode
By rotating only the data 700, payment preparation is performed.

On the other hand, if it is determined that the genuine bill signal has not been received, the CPU 501 returns to step S16 and maintains the standby state. When payment preparation is done, CP
The U501 sends a genuine note confirmation signal to the identification unit MPU501a (step S19). The identification unit MPU 501 a
It is determined whether a genuine bill confirmation signal has been received from U501 (step S20).

As a result, when the identification unit MPU 501a receives a genuine bill confirmation signal, the identification unit transport motor 108
Rotates in the depositing direction, and the banknote 1 in the temporary standby unit 100b is transported to the banknote transport unit 200 (Step S2).
1). At this stage, since the electromagnetic clutch 109 is off, even if the next bill 1 is inserted from the bill insertion slot 101, the transport belt 114 is not driven and the next bill 1 is not taken in. Thereafter, the identification unit MPU 501a waits for another genuine bill confirmation signal from the CPU 501 (Step S).
22).

On the other hand, the bill 1 sent to the bill transport unit 200
Passes through the conveyance path sensor-255 unless a trouble such as a jam occurs on the way (step S23). Banknote 1
When the rear end of the sheet has passed the conveyance path sensor-255, C
The PU 501 sends a genuine bill confirmation signal to the identification unit MPU 501a (Step S24).

The discriminating unit MPU 501a determines whether or not a genuine bill confirmation signal has been received (step S25). As a result, when a genuine bill confirmation signal is received, the identification unit transport motor 108 stops (step S26). On the other hand, if the genuine bill confirmation signal has not been received, step S2
The standby state of No. 2 is maintained. When the recognition unit transport motor 108 stops, the bill recognition unit 100 returns to the standby state in which the next bill 1 can be deposited, and the operation of the bill recognition unit 100 ends (step S27).

On the other hand, the banknote 1 passing through the transport path sensor-255 is transferred from one of the transport gates 231, 261, 291 to the respective stackers 300a, 300a.
b, 300c. Here, taking the case of a thousand-yen bill as an example, the thousand-yen bill passes through the stack entrance sensor 307 provided in the bill conveyance port 301 (step S28). Steps S28 to S33 will be described using a 1000-yen bill as an example, but the steps are the same for other bills.

The trailing end of the 1,000 yen bill is the stack entrance sensor-3.
07, the CPU 501 receives a signal from the stack entry sensor 308 and stops the stepping motor 700 after a sufficient time has passed for the bill 1 to be completely stored in the stacker 300a. (Step S29). When the stepping motor 700 stops, each of the transport belts 304 and 312 of the transport mechanism 309 stops. Then, the banknote 1 is placed on the stack arm 332 which presses the upper surface of the banknote 1 stored in the stacker 300a.

Next, the lift motor 333 makes a half turn in a direction to raise the stack arm 332 (step S).
30). Banknote 1 placed on the stack arm 332
Is in contact with each of the conveyor belts 304 and 312 and receives a downward force from between the two plates of the stack arm 332. Subsequently, the bill 1 slips downward from between the two plates of the stack arm 332, and is pushed.
It is placed on the bill 1 on the plate 325. afterwards,
The stack arm 332 stops at a predetermined position above the transport belts 304 and 312.

When the stack arm 332 stops, the CP
In accordance with the instruction of U501, the stepping motor 700 rotates in the depositing direction (step S31). In this embodiment, the stepping motor 700 rotates 24 steps in the deposit direction. Even if there is a banknote 1 that does not reach the depth of the stacker 300a at the time of payment, the banknote 1 is placed by aligning its ends with other stored banknotes 1 by such a tidying operation.

Next, the stack arm 332 is lowered by the half rotation of the lift motor 333, and stops at the position where the stack lift down sensor-341b is turned on (step S32). As a result, the pusher plate 3
25 is the stored bill 1 including the deposited bill 1
Is loaded by the stack arm 332.

Then, the 1,000 yen gate solenoid 232 is turned off (step S33), the 1000 yen transport gate 231 is closed, and a notification of the registration of payment is sent to the control device 509 of the host machine. Thus, the deposit operation of the bill storage device is completed (step S34). Then, at the same time, the operation of the control device 509 of the host machine ends (step S35).

(10) Withdrawal operation

Next, the dispensing operation will be described with reference to an example of dispensing two 1000-yen bills. 54 and 55
The flowchart of the dispensing operation is shown in FIG. Hereinafter, the dispensing operation of the bill storage device will be described in accordance with the flowchart.

A withdrawal notice serving as a signal for dispensing two 1000-yen bills is sent from the control device 509 of a host machine such as a vending machine to the CPU 501 (step S51).

The CPU 501 sends a deposit prohibition signal to the bill discriminating section 100 to put the bill discriminating section 100 into a deposit prohibiting state (step S52). By the previous withdrawal notice, CPU
501 controls the bill storage unit 300 and the bill transport unit 200. That is, the eject gate solenoid 227 of the bill transport unit 200 is turned on, and the eject transport gate 226 is opened. At the same time 1,000 yen gate solenoid 232
Is turned on, and the 1,000 yen transfer gate 231 is opened. The stack motor is rotated by the rotation of the lift motor 333.
The program 332 rises (step S53).

The top surface of the banknote 1 at the top of the banknotes 1 stacked on the pusher plate 325 is
4, 312, the pusher plate 32
5 stops. At this time, the end stopper-334 is in a state where the rear end of the bill 1 is lightly pushed down by the elastic force of the spring 335.

Next, as the stepping motor 700 rotates in the dispensing direction, each of the transport belts 304 and 31 is rotated.
2 is driven in the dispensing direction (step S54). As a result, the uppermost banknote of the stored 1,000-yen bill is carried out from the stacker 300a toward the banknote transfer slot 301. At this time, the second 1,000-yen bill is also
4, 312 receives driving in the dispensing direction. However, the separation roller-310, the friction roller 320, and the roller guide 311 provided in the bill conveyance port 301 prevent the bill from jumping out of the stacker 300a.

When the tip of the 1000-yen bill carried out of the stacker 300a passes through the stack entrance sensor 307 (step S55), the stack entrance sensor 307
Sends a signal to the CPU 501. Then, the CPU 501
Turns on the stack bill brake solenoid (step S56). As a result, the stopper arm 348 provided at the rear end of the transport mechanism 309 rotates, and
A brake member 351 connected to the front end 350a of the key 350 is pressed against the rear end of the second 1,000-yen bill.
At the same time, the roller arm 353 rotates, and the roller-354 at the tip pushes downward from the upper surface of the first 1,000-yen bill. As a result, the first 1,000-yen bill and each of the transport belts 304 and 312 are separated.

The first 1,000-yen bill is a contact portion between the upper roller 302 of the stack entrance and the lower roller 303 of the stack entrance and a holding portion between the separation roller 310 and the roller 317. In response to the drive of the transport belt 304, the bill transport unit 20
Transported to zero. Thousand-yen bill is stack entry sensor-30
7, the length of the bill 1 and the light transmission pattern are detected by the sensor 307 (step S57).

The trailing end of the 1,000 yen bill is the stack entrance sensor-3.
07 (step S58), the stack bill brake solenoid is turned off (step S59). In addition, the brake arm 350 and the roller arm 353 are
The bill 1 inside the stacker 300a is prevented from being transported while it is lowered.

Next, the CPU 501 receives the data signal from the stack entrance sensor 307, and judges whether or not double feeding has occurred (step S60). As a result, if it is determined that multiple feeds are being performed, the process proceeds to step S61, and reject processing as described later is performed.

On the other hand, if it is determined that the double feed has not occurred,
The PU 501 determines whether or not the bill 1 is correct, that is, whether or not the bill 1 is a 1,000-yen bill (step S62). As a result, if it is another type of banknote 1, the rejection process of step S61 is performed. In addition, as a result of identification of banknote 1,
If it is determined that the bill is genuine, the 1,000-yen bill is transferred from the eject transport gate 226 that has already been opened to the eject section 40.
0a (step S63).

Next, the CPU 501 determines whether or not the designated number of banknotes 1, that is, two 1000-yen bills in this example, has been conveyed (step S64). If only one sheet has been conveyed, the operation from step S54 is repeated to further send the banknote 1 to the ejecting unit 400a. In addition,
Until the second 1,000-yen bill is conveyed to the eject unit 400a, the previously conveyed 1,000-yen bill remains on the temporary holding plate 410 of the eject unit 400a.

On the other hand, when the designated number of banknotes 1, that is, two thousand-yen bills in this example, is conveyed to the eject section 400a, the stepping motor 700 rotates in the depositing direction (step S65). In this embodiment, the rotation is performed by 24 steps.

Next, by rotating the lift motor 333 half a turn, the stack arm 332 is moved downward, and the pusher plate 325 is moved to the bill transfer port 30 by the pusher plate 325.
Push down below 1 (step S66). continue,
A signal is sent from the CPU 501 to the eject gate solenoid 227 and the thousand yen gate solenoid 232, and the solenoids 227 and 232 are turned off. by this,
Eject transport gate 226 and 1,000 yen transport gate 23
1 is closed (step S67).

Next, the CPU 501 rotates the eject lift motor 471 to lower the lift base 450 (step S68). Eject lift motor 4
By the rotation of 71, a lift sensor (not shown) provided in the rotating arm 473 is turned on. CPU 501
Confirms whether or not the lift sensor is on (step S69), and if it is not on, error processing is required (step S70).

On the other hand, if the lift sensor is on, the CPU 501 turns on the eject shutter solenoid 440 (step S71). As a result, the temporary holding plate 410 overlaps the bill dispensing drive unit 420. The bill 1 pressed downward by the lift base 450 causes the magnet 428 provided below the bill detection plate 427 to overlap the ejected bill presence / absence sensor-429.

On the other hand, when the temporary holding plate 410 is lowered,
The shutter 413 of the bill dispensing port 401 is opened. At this time,
The bending arm 442 rotates, and the eject shutter upper sensor-443a is turned on. The CPU 501 includes an eject bill sensor 429 and an eject shutter.
It is determined whether or not both of the upper sensors-443a are on (step S72). As a result, both sensors 42
If 9,443a is not on, error processing is required (step S70).

On the other hand, if both sensors-429 and 443a are on, CPU 501 rotates stepping motor 700 in the dispensing direction (step S73). Thereby, all the banknotes 1 placed on the temporary holding plate 410 are driven in the dispensing direction. When the bill 1 moves in the dispensing direction and passes through the bill detection plate 427, the plate 427 rises. The CPU 501
It is checked whether or not the ejected bill sensor 429 has been turned off (step S74).

As a result, the eject banknote presence / absence sensor-4
If 29 remains on, error processing is required (step S75). On the other hand, if the ejected banknote sensor 429 is turned off, the stepping motor 70 is turned off.
0 stops (step S76). In this state, the leading end of the banknote 1 is about half of the banknote outlet 401.

Then, the standby state is maintained until the bill 1 is pulled out and the eject outlet sensor 444 is turned off (step S77). When all the banknotes 1 are pulled out, the CPU 501 sets the ejection outlet sensor-4.
It is determined whether or not 44 has been turned off (step S7)
8). If the eject outlet sensor-444 is not turned off, the process returns to step S76 and is left as it is.

When the eject outlet sensor 444 is turned off, the eject lift motor 471 rotates and the lift base 450 rises (step S79). Further, the temporary holding plate 410 is lifted upward from the bill dispensing drive unit 420. Thereby, the bill dispensing port 401
Shutter-413 is closed.

Next, the CPU 501 sends a deposit prohibition cancel signal to the banknote recognizing section 100 in the deposit prohibited state. Thereby, the deposit prohibition state of the banknote recognition unit 100 is released (step S80), and the banknote recognition unit 100 returns to the original state and ends the operation (step S8).
1).

On the other hand, the CPU 501
09 is notified that the dispensing operation has been completed, and the operation of the bill storage device ends (step S82), and the operation of the host machine control device 509 also ends (step S8).
3).

(11) Rejection operation

Next, a description will be given of a reject operation performed when the above-described normal depositing operation or dispensing operation is not performed, that is, when a jam, a double feed, a mixed bill is mixed, or the like.

If a trouble occurs during the depositing operation or the dispensing operation, a mechanism for facilitating removal of the jammed banknote 1, a mechanism for transporting the banknote 1 to the reject unit 400b, and an error message are displayed after an error is displayed. -It is supported by adopting a mechanism for performing processing. Among these, the reject operation of transporting the banknote 1 to the reject unit 400b is defined as when a jam occurs during the deposit, when the banknote 1 causes double feeding at the time of dispensing, or at the time of dispensing.
Are carried out in three cases when is transported.

The error process is a process performed by a manager manually when the banknote 1 cannot be transported to the reject unit 400b, for example, when a jam occurs at the time of dispensing.

FIG. 56 shows a flowchart of a reject operation when the banknote 1 is jammed at the time of deposit. Hereinafter, description will be made according to the flowchart. The operation from the insertion of the banknote 1 into the bill insertion slot 101 of the banknote recognition unit 100 to the conveyance of the banknote 1 to the banknote conveyance unit 200 is the same as the depositing operation, and a description thereof will be omitted.

[0270] If the jam occurs somewhere while the bill 1 is moving in the bill transporting section 200, a reject operation is started (step S101). The detection of the occurrence of a jam is performed as follows. That is, when the banknote 1 does not reach the stack entrance sensor 307 provided at the entrance of each of the stackers 300a, 300b, and 300c with the number of steps within a predetermined range from the transport path sensor -255,
It is determined that a jam has occurred. The determination is made based on the number of steps of the stepping motor 700 because the number of steps when the bill 1 normally passes between the two sensors -255 and 307 falls within a predetermined range.

When a jam occurs, first, the rotation of the stepping motor 700 is stopped, and the conveyance belt 202 is stopped.
Drive stops. (Step S102). Here, the jam occurs in a state where the banknote 1 is detected by the transport path sensor-255, and in a position where the banknote 1 is not detected by the sensor-255. In the former jam, the banknote 1 (especially, a 1,000-yen bill) is a stacker for a 1,000-yen bill
Thousand-yen transfer gate 2 immediately before bill transfer port 301 at 0a
This is a jam that occurs at the part entering the position 31.

In the latter jam, for example, a 5,000-yen bill or a 10,000-yen bill is transferred to each of the transport gates 261 and 29.
This is a jam that occurs at the part that goes into 1. Since the reject operation differs depending on the two types of jams, the CPU
In step S103, first, the transport path sensor-255 receives light reflected on the banknote 1 and determines whether the light is on.

As a result, when the conveyance path sensor-255 is on, the CPU 501
A signal is sent to 0 to rotate the stepping motor 700. As a result, the transport belt 202 is driven in the dispensing direction (step S104). Driving can be performed for a preset number of steps, but in this embodiment, driving can be performed up to a maximum of 200 steps.

As a result of driving the transport belt 202 in the dispensing direction, the CPU 501 determines whether or not the bill 1 has passed the transport path sensor-255 and the sensor-255 has been turned off (step S105).

As a result, when the conveyance path sensor-255 is not turned off, the jam cannot be eliminated by driving the conveyance belt 202 in the dispensing direction. Therefore, an error process is required (step S106). On the other hand, when the conveyance path sensor-255 is turned off, the stepping motor 700 is stopped by the signal from the CPU 501 (step S10).
7).

At this stage, the banknote 1 exists on the outer surface of the eject transport gate 226 immediately before the banknote transport port 402 of the eject / reject unit 400. Therefore, from this state, the banknote 1 is directly
Cannot be transported to b. Therefore, first, the CPU 501 turns off the transfer gate solenoid (usually, the 1,000 yen gate solenoid 232) to close the open transfer gate (step S108).

Next, the stepping motor 700 is rotated in the deposit direction to drive the transport belt 202 in the deposit direction (step S109). Such driving can be performed for a preset number of steps, but in this embodiment, driving can be performed up to a maximum of 300 steps. While the transport belt 202 is being driven in the depositing direction by a predetermined number of steps, the CPU 501 determines whether or not the rear end of the bill 1 has passed through the transport path sensor -255 and has been turned off (step S110). .

As a result, if the trailing end of the bill 1 does not pass through the conveyance path sensor -255 and the sensor -255 remains on, an error process is required (step S).
111). On the other hand, if the transport path sensor-255 is turned off, it means that the bill 1 has passed through the eject transport gate 226. The CPU 501 turns on the eject gate solenoid 227 and turns on the eject transport gate 22.
6 is opened (step S112).

Next, the CPU 501 sends a signal to the eject / reject unit 400 to rotate the eject lift motor 471. The lift base 450 that has been waiting in the reject unit 400b moves downward to be ready to receive the jammed banknote 1 (step S11).
3).

Next, the CPU 501 executes the stepping mode.
Is rotated. Thereby, the transport belt 20
2 is driven in the dispensing direction (step S114). The jammed banknote 1 is sent to the eject / reject unit 40.
0 from the transport base 226 to the lift base 45
Conveyed above zero. At this time, the eject entrance sensor
By 403, passage of the banknote 1 is confirmed (step S115).

Thereafter, the eject lift motor 471 rotates, and the lift base 450 is moved to the reject section 400b.
To rise. The lift base 450 is a rotating arm 48.
5 and stops on the reject unit 400b in a state where the holding plate 488 and the foreign currency 2 are stacked (Step S1).
16). With the above operation, the rejection operation of the banknote 1 that has been jammed in the vicinity of the 1,000 yen transport gate 231 is completed (step S117).

On the other hand, when a 5,000-yen bill or a 10,000-yen bill causes a jam in the vicinity of each of the transfer gates 261, 291, the operation becomes simpler than when a 1,000-yen bill causes a jam. . This is because the banknote 1 is not located at the portion of the ejection transport gate 226 and does not hinder the opening operation of the gate 226 during a jam. Specifically, step S1
At 03, if the conveyance path sensor-255 is off, the operation starts from step S112.

As described above, when a jam occurs at the time of deposit, the bill 1 is conveyed to the reject unit 400b instead of simply displaying an error. This is because when a jam occurs in the depositing direction, it is highly likely that the jam will be resolved by driving in the opposite direction, and the processing can reduce the maintenance labor of the apparatus. In addition, the reject processing, not the re-deposit processing,
This is because the paper money 1 is damaged and there is a risk that jam will occur again.

FIG. 57 shows a flow chart of the reject operation in the case of multi-feeding or in the case of dispensing a different bill 2.
Show Hereinafter, description will be given according to this flowchart.

After a dispensing signal is sent from the host machine control device 509 such as a vending machine to the CPU 501, each stacker
The operation until the bill is carried out from 300a, 300b, and 300c is common to the above-described normal dispensing operation, and thus the description is omitted.

Each of the stackers 300a, 300b, 300c is placed in a state where the second bill 1 is in close contact with the first bill 1.
So-called double feed may occur. While the bill 1 is passing through the stack entrance sensor 307, the length and the light transmission pattern of the bill 1 are detected by the sensor 307.

The CPU 501 determines from the length of the bill 1 and the light transmission pattern whether the bill 1 is not multi-fed or is not a different bill 2. Normally, banknote 1
Since the length of the bill 1 is longer than the predetermined length, it is sufficient to identify only the length of the bill 1.

However, if the bills 1 are almost overlapped, the length is almost the same as the length of one bill 1 and it is difficult to detect the double feed. Therefore, the multi-feed of the banknote 1 is determined by measuring the light transmission pattern. When the double feed or the conveyance of the foreign ticket 2 is performed, the CPU 501
Starts the following operation (step S151).

When it is determined that the multi-fed banknote 1 or the foreign bill 2 has been conveyed, first, the eject entrance sensor-4
It is confirmed whether or not the banknote 1 exists near 03 (step S152). When dispensing a plurality of banknotes 1 and the banknotes 1 in progress are present in the vicinity of the ejection entrance sensor 403, the banknotes 1 are transmitted to the ejection entrance sensor 403. The driving of the conveyor belt 202 is continued until the sheet passes through (step S153).

On the other hand, when there is no bill 1 near the eject entrance sensor 403, the stepping motor 700
To stop. At this time, the stack bill brake solenoid is kept on, and the stacker 300a is in a state of stopping the dispensing of the next bill 1 (step S15).
4).

Next, the CPU 501 rotates the eject lift motor 471. As a result, the reject unit 4
The lift base 450 waiting at 00b moves downward to enter a system for receiving the multi-fed bills 1 and foreign bills 2 (step S155).

Thereafter, the CPU 501 rotates the stepping motor 700 (step S156). As a result, the conveyor belt 202 is driven in the dispensing direction, and the multi-fed banknotes 1 and foreign bills 2 on the conveyor belt 202 are lifted by the lift base.
Is transported on the surface 450.

Next, the passage of the multi-fed bill 1 or the foreign bill 2 is confirmed by the eject entrance sensor 403 provided in the bill transport port 402 (step S157). Then, the eject lift motor 471 rotates and the lift base 450 rises to the reject unit 400b. The lift base 450 stops at the reject unit 400b in a state where the banknote 1 or the foreign bill 2 which has been multi-fed with the pressing plate 488 is stacked. If the multi-fed banknote 1 or the like is not confirmed, an error process is required (step S15).
8).

On the other hand, the drive of the conveyor belt 202 can be moved by a preset number of steps. In this embodiment, a maximum of 1000 steps can be set. The stepping motor 700 is rotated by the set number of steps, and an operation for confirming whether or not the multi-fed banknote 1 or the like is still at a position detected by the stack entrance sensor 307 or the conveyance path sensor 255 is performed. (Step S159).

As a result of the confirmation, when the multi-fed banknote 1 is located at a position detected by the sensors 307 and 255,
Error processing is required (step S160).
On the other hand, when the multi-fed bills 1 and the like are not detected and all the multi-fed bills 1 are placed on the lift base 450, the lift base 450 by the eject lift motor 471 is used.
Is performed (step S161). Subsequently, the stack bill brake solenoid is turned off, and the double feed prevention mechanism is released (step S162).

Next, the so-called banknote sorting operation is performed so that the stepping motor 700 rotates in the depositing direction and does not cause double feeding again (step S16).
3). Subsequently, the operation for dispensing the next banknote 1 is started (step S164). With this series of operations, the reject operation ends (step S165).

[0297] Next, the operation when a jam occurs at the time of dispensing will be described. Hereinafter, description will be made in accordance with the flowchart of FIG.

First, the CPU 501 determines that a jam has occurred while the banknote 1 is being conveyed, as described above.
Detection is performed based on the number of steps between 07 and 255 (step S181). Then, the CPU 501 stops the rotation of the stepping motor 700. As a result, the driving of the transport belt 202 stops (step S182).

Each of the transfer gate solenoids 232 and 262 is kept on (step S183). This is because, if a jam occurs near the transport gates 231 and 261 and the transport gates 231 and 261 are closed, the bill 1 is damaged. In addition, it is not possible to remove the jammed banknote 1.

It should be noted that the jam at the time of dispensing does not need to be conveyed to the reject unit 400b and requires an error process (step S184). Thus, the administrator of the bill storage device opens the transport path door unit 201 and removes the bill 1. With this operation, the rejection operation for the jam at the time of dispensing ends (step S185).

The above embodiment is an example of a preferred embodiment of the present invention, and the present invention is not limited to the embodiment, and various modifications can be made without departing from the gist of the present invention. .

For example, the stacker shown in FIG.
The program 332 may have a structure as shown in FIG.
Hereinafter, the structure and operation of the stack arm will be described with reference to FIG. The pusher plate 32 provided inside the stacker 300a shown in FIG.
5, the transport mechanism 309 and the like are common to the stacker 300a shown in FIG.

The stack arm 801 is provided with a separation roller-3.
It is rotatable by drive means connected to a shaft 318 that is coaxial with 10. Also, a stack arm 801
Is a width capable of pressing the upper end surface of the bills 1 stacked on the pusher plate 325, and
It is composed of two arms wider than 09.

The length of the two arms is long enough to hold the leading end of the bill 1. Stack Arm 8
The main role of 01 is to prevent a collision between the banknote 1 deposited at the time of deposit and the loaded paper sheet 1 and at the time of withdrawal,
The purpose is to suppress the rise of the pusher plate 325. Therefore, even with the length shown in FIG. 60, such a role can be sufficiently performed. Further, when the length of the stack arm 801 is reduced, there is an advantage that the driving mechanism of the stack arm 801 can be downsized.

Next, a description will be given of a deposit operation for transporting the bill 1 into the stacker 300a using the stack arm 801 and a dispensing operation for transporting the bill 1 to the outside of the stacker 300a.

First, regarding the deposit operation, the flow of FIG.
This will be described with reference to the chart and FIG.

When depositing the banknote 1, the stack arm 8
Reference numeral 01 denotes a pusher-press on the upper side of the stored banknote 1 by rotating the arm inside the stacker 300a.
325 is stopped at the position A where it was pushed down.
The depositing operation starts from such a standby state (step S2).
31).

In the payment standby state, the stored banknote 1
A space is formed between the upper surface of the belt and each of the conveyor belts 304 and 312. Therefore, roller-3 on the stack entrance
The banknotes 1 deposited by driving the transport belt 304 wound around 02 are conveyed into the stacker 300a without colliding with the banknotes 1 already stored. The deposited banknotes 1 are stacked in a state of being bent on the upper surface of the stored banknotes 1 in a state where the leading end thereof is placed on the stack arm 801 (step S232).

Next, the stack arm 801 is connected to the shaft 318.
59 is rotated counterclockwise in FIG. 59 (step S233). The pusher plate 325 rises by the elastic force of a spring (not shown). Stack Arm 8
When 01 is rotated to the illustrated portion B, the deposited banknotes 1 fall out from between the stack arms 801 and are stacked on the stored banknotes 1. At the same time, the pusher plate 325 stops in a state where the deposited bill 1 is in contact with each of the transport belts 304 and 312 (step S234).

[0310] The stack arm 801 continues to rotate further from the section B and stops at the section C outside the stacker 300a (step S235). Next, stepping motor 7
The rotation of 00 causes the upper roller 302 of the stack entrance to be driven in the direction opposite to the dispensing direction. That is, the deposited banknote 1 is placed with its end aligned with the stored banknote 1,
A so-called tidy operation is performed (step S236).

[0311] When the tidy operation is completed, the stack arm 801 rotates clockwise from the portion C in Fig. 59 (step S237). Stack arm 801 is B
After that, the stack arm 801 pushes down the pusher plate 325 from the upper surface of the deposited banknote 1 (step S238). This pressing is performed against a spring that urges the pusher plate 325 upward.

[0312] Then, the stack arm 801 rotates to the A section and stops (step S239). With this series of operations, the deposit operation is completed (step S24).
0).

FIG. 61 shows the stacker 300 shown in FIG.
This is a flowchart of the dispensing operation of a. The dispensing operation will be described below with reference to the flowchart of FIG. 61 and FIG.

Before the withdrawal operation, the stack arm 801
Pushes down the pusher plate 325 at the portion A shown in FIG. The dispensing operation starts and starts from such a standby state (step S251). First, the host machine control device 50
From step 9, a withdrawal signal is output to the control unit 500 (step S252). The stack arm 801 rotates counterclockwise in FIG. 59 (step S253).

The pusher plate 325 rises following the rise of the tip of the stack arm 801 by the elastic force of a spring (not shown) (step S254).
Then, when the stack arm 801 reaches the section B shown in the figure, the pusher plate 325 stops in a state where the upper surface of the stored banknote 1 is in contact with each of the transport belts 304 and 312 (step). S255). Stack A
The arm 801 continues to rotate further and stops at the point C (step S256).

Next, the stepping motor 700 rotates, and each of the conveyor belts 304 and 312 is driven in the dispensing direction (step S257). Each conveyor belt 304, 312
, The uppermost banknote 1 of the stored banknotes 1 is dispensed from the banknote transfer slot 301 to the outside of the stacker 300a (step S258).

After the dispensing, the respective conveyor belts 304 are driven in the direction opposite to the dispensing direction, so that the so-called tidying operation of aligning the ends of the stored bills 1 is performed. As a result, the banknote 1 that has protruded outward from the stacker 300a at the time of dispensing.
Is returned to the normal position of the stacker 300a (step S259). When the tidy operation is completed, the stack
The drum 801 rotates clockwise from the part C to the part B in FIG. 59 (step S260).

The stack arm 801 pushes down the pusher plate 325 against the upward bias of the spring (not shown) in the process from the portion B to the portion A (step S2).
61). Then, the stack arm 801 stops at the section A and the pusher plate 325 stops (step S262). With this series of operations, the dispensing operation ends (step S263).

The stack arm 801 may be configured to be rotatable using a drive other than the motor, for example, an elastic force such as a mainspring or a spring.

[0320] The members and structures used in the bill storage device in each of the above embodiments may be the following members and the like.

For example, the transport belt 304 as shown in FIG. 14 wears out as the bill storage device is used for a long time. On the other hand, the banknotes 1 conveyed to the inside or outside of the stacker 300a are separated from the stack entrance upper roller 302, roller 317, separation roller -3 as shown in FIG.
10 pinched.

[0322] Therefore, when the transport belt 304 is worn, the paper currency 1 is more likely to be pinched by the transport belts 304 and 312 and the separation roller-310. Therefore, there is a possibility that the separating action is reduced and double feeding is likely to occur.

Therefore, as shown in FIGS. 62 to 65,
A belt wear tracking mechanism 810 that pushes down the transport belt 304 downward following the wear of the transport belt 304 to maintain a constant pinching force may be provided.

FIGS. 62 and 63 are a side view and a perspective view of the belt wear following mechanism 810, respectively. Hereinafter, according to these figures, the belt wear following mechanism 8 will be described.
The structure of No. 10 will be described.

As shown, the belt wear following mechanism 810 is provided with a roller 8 provided at a position in contact with the upper surface of the lower conveyor belt 304b below the conveyor belt 304.
11 and a roller 81 provided at a position in contact with the upper surface of the upper conveyor belt 304a above the conveyor belt 304.
2 and a supporting column 813 connecting the two. Prop 813
The upper end 813a of the support 813 is connected to a plate tip 814a of a plate 814 disposed substantially perpendicular to the support 813.

Further, the support 813 is connected to the transport belt 304.
Shaft 8 so that it can move up and down in the vertical direction following the wear of
15. The roller 816 is fixed at a position in contact with the lower surface of the upper conveyor belt 304a.
However, the rollers 816 are not connected to the columns 813. A part of the plate 814 and the upper wall of the stacker 300a are connected via a spring 817 such that the rollers 811 and 812 are urged downward.
The plate tip 814b of the plate 814 is fixed.

Therefore, when the transport belt 304 is worn, the plate 814 rotates clockwise in FIG. 62, and the column 813 moves downward. That is, the plate 814 rotates around the plate tip 814b, and the roller 812 moves the upper conveying belt 304a to the roller 81.
Continue to sandwich between 6. On the other hand, the roller 811 pushes down the lower conveyor belt 304b by descending by the same amount as the wear amount of the conveyor belt 304.
The plate tip 814b is fixed to a one-way clutch 818 that can rotate only clockwise. Therefore, the column 813 has a structure that cannot be raised once lowered.

FIGS. 64 and 65 show a comparison of the state of the stacker entrance with and without the belt wear following mechanism 810. FIG. First, the belt wear following mechanism 81 shown in FIG.
The case where there is no 0 will be described. When the transport belt 304 wears and decreases from the original thickness (A) to B, the distance C between the upper surface of the roller of the separation roller-310 and the lower surface of the transport belt 304 becomes C- (A −B). Therefore, the pinching force of the banknote 1 by the transport belt 304 and the separation roller-310 is reduced, and double feeding is facilitated.

Therefore, if the belt wear following mechanism 810 as shown in FIG. 65 is provided, such a problem is eliminated. The roller 811 of the belt wear following mechanism 810 is
The transport belt 304 is lowered by the wear amount, that is, AB. Therefore, when the roller 811 is lowered, the transport belt 304 is slightly inclined toward the inside of the stacker 300a. For this reason, the distance between the upper surface of the separation roller 310 and the conveyor belt 304 is a distance D that is as close as possible to C than C- (AB). Since this operation is performed following the wear of the transport belt 304, the distance between the upper surface of the separation roller-310 and the transport belt 304 is always
It is kept almost constant. Therefore, the separating action is kept constant.

If the transport belt 304 continues to wear and breaks, the bill storage device becomes unusable. Therefore, in order to prevent such a state, a mechanism may be provided to notify the exchange of another consumable member (for example, a roller) including the transport belt 304 when the transport belt 304 reaches a certain thickness. For example, the one-way clutch 8 shown in FIG.
A method is also conceivable in which a warning lamp is turned on through the control unit 500 when the rotation amount of the motor 18 reaches a predetermined amount.

Also, by providing a light emitting element of an infrared sensor in a part of the belt wear following mechanism 810,
A warning may be issued by detecting a change in the amount of light due to a deviation from the light receiving element of the infrared sensor provided on the wall surface of the stacker 300a.

The transfer gate 231 as shown in FIG.
It is also possible to reverse the center claws 231a and the claws 231b, 231c on both sides with respect to the structure inside each claw.

FIG. 66 shows the 1000 yen transfer gate 23 shown in FIG.
1 shows a transport gate in which the back structure of the claw 231a and the back structure of the claws 231b and 231c at both ends of the same gate 231 are reversed. On the back side of the claws 231b, 231c on both sides, respective rollers 820, 821, 822, respectively.
823 and a belt 824 stretched over them. The belt 824 is a mechanism that rotates following the conveyor belt 202 driven by the rotation of the stepping motor 700.

[0334] A belt 825 is provided at a portion located behind the center claw 231a when the 1,000 yen transport gate 231 is closed. The belt 825 is connected to each roller.
826, 827, 828
It can be rotated following the data 700.

The roller 829 is arranged at a position facing the roller 827 wound around the belt 825. Further, the roller 830 includes the roller 822 and the belt 82.
4. Roller 830
Is wound around the transport belt 211.

Therefore, the 1000-yen bill transported by driving the transport belt 202 and the transport belt 211 enters the open 1,000-yen transport gate 231 and the two belts 8 on both ends are moved.
24, and heads for the 1000-yen bill stacker 300a. Next, the tip portions on both sides of the 1000-yen bill are drawn between the belt 824 and the transport belt 211 wound around the roller 830, respectively. At the same time, the central leading end of the 1,000-yen bill is drawn between the belt 825 and the roller 829. In this way, the tip of the 1,000-yen bill is smoothly drawn into the 1000-yen stacker 300a without being locally driven by a belt or the like.

Further, by changing the ratio of gears meshing with the stepping motor 700 or the diameter of the pulley, or by driving the stepping motor 700 with a motor separate from the stepping motor 700, the belt 825 is moved to the conveying belt 211. It is also possible to drive at a higher speed. Thus, the bill 1 is transferred from the 1,000-yen transfer gate 231 to the 1,000-yen bill stacker 300a.
Can be transported so that the leading end of the banknote 1 is positively pulled.

The 5000 yen transfer gate 261 has the same structure and mechanism as the 1000 yen transfer gate 231. Therefore, when a 5,000-yen bill is deposited, the 5,000-yen bill is loaded into the 5,000-yen bill stacker 300b in the same manner as the above-mentioned 1,000-yen bill.

The 10,000-yen transfer gate 291 has the shape of a single claw at the center.
1 has the same structure and mechanism as the center tab 231a. Therefore, the central portion of the tip of the 10,000-yen bill is the belt 82 disposed below the central claw 231a shown in FIG.
5 is driven by a belt disposed at the same position as that of the belt 5.

The 5,000-yen transfer gate 261 and the 10,000-yen transfer gate 291 can also transfer the banknote 1 at high speed by a motor provided separately from the stepping motor 700. is there.

As described above, each of the transfer gates 231 and 26
By providing a driving belt on the back side of the first and second 291, the stackers 300 a,
Jams are less likely to occur even on a conveyance path that bends into 300b and 300c. In addition, one of the methods for preventing a jam is to prevent the transport path of the banknote 1 from being sharply bent. However, this increases the size of the bill storage device. For this reason, in this embodiment, the size of the apparatus is reduced by making the transport path of the banknotes 1 substantially right-angled and making effective use of rollers and belts.

Further, the thermometer as the temperature detecting means employed in each of the above embodiments may be another temperature detecting means such as a thermocouple. Further, the place where the temperature detecting means is installed is the side wall of the stepping motor 700, but is not limited to such a place. It may be provided inside the stepping motor 700, in the vicinity of other components such as the conveyor belt, or outside the bill storage device. Further, the heat value of the stepping motor 700 is changed by changing the current. However, the heat value may be changed by changing the resistance while keeping the current constant. In addition, when the amount of heat generated by the stepping motor 700 is changed, it is not limited to the case where the temperature to be detected becomes 5 ° C. or less,
Any temperature such as ° C. can be selected.

Also, in the above-described embodiment, a system in which the stepping motor 700 generates heat at low temperatures has been described. However, when the temperature rises in midsummer, the current flowing through the stepping motor 700 is reduced or the resistance is reduced. This makes it possible to reduce the amount of heat generated by the stepping motor 700. Stepping motor 70
This is because there is a risk that normal conveyance may not be possible due to overheating of the stepping motor 700 or elongation of the conveyance belt or the like due to the heat generated by the heat generation and the heat received from the outside. The temperature at which the heat generated by the stepping motor 700 is reduced can be set to an arbitrary temperature, for example, 120 ° C. depending on the components of the apparatus. That is, 120 ° C
When the above temperature is detected, the stepping motor 700
And the like that flows through it.

In the above-described embodiment, the current flowing when the stepping motor 700 is stopped is changed to change the calorific value of the stepping motor 700. However, the current is supplied to the stepping motor 700. Even when the temperature is not present, it is also possible to generate heat by passing an electric current when the temperature detecting means detects a temperature lower than a predetermined temperature.

The motor is a stepping motor 70.
A motor other than 0, for example, an AC motor or a DC motor may be used. However, when using a DC motor,
If a direct current is supplied to provide a role as a heater, the motor will rotate. Therefore, it is necessary to provide separate circuits for the rotation system and the heater system. Further, the calorific value of the driving means may be a constant calorific value without being continuously changed according to the temperature detected by the temperature detecting means.

Although the power supply for rotating the stepping motor 700 is a 24V DC power supply, it is not limited to 24V, and any voltage in the range of 10 to 30V can be applied. In the present embodiment, a 24 V DC power supply is employed from the viewpoint of ensuring safety in the event of leakage and ensuring a sufficient voltage for driving.

Furthermore, in Japan at present, as described above, by providing a stacker for three kinds of banknotes of 1,000 yen bill, 5,000 yen bill, and 10,000 yen bill, it becomes the most preferable bill storage device. Alternatively, a device for one type of banknote, a device for two types of banknotes, or a device for four or more types of banknotes may be used in accordance with the demands of the times and requests for use.

For example, even if one or more stackers of any one kind of a 1,000-yen bill, a 5,000-yen bill, and a 10,000-yen bill are provided, a 1,000-yen bill, a 5,000-yen bill, a 10,000-yen bill and a 1,000-yen bill One or two or more stackers for storing only yen notes or 10,000 yen bills and 5,000 yen bills may be provided.

[0349]

According to the first aspect of the present invention, when the motor is stopped, the bill storage device changes the current or resistance flowing inside the motor without driving the motor, thereby generating heat of the motor. Since the amount is changed, when the motor is stopped, the motor and other components can be warmed or excessive heat generation can be suppressed. Therefore, assuming lower price and smaller size of the device,
High reliability of bill processing can be secured.

According to the second aspect of the present invention, the bill storage device changes the calorific value of the motor when the temperature detecting means detects a temperature lower or higher than a predetermined temperature. The temperature inside the device can be adjusted only when the temperature is low or high. Therefore, even when the temperature outside the banknote storage device is low or high, there is no danger that the motor and other driving members will freeze or overheat and hinder the operation.

According to the third aspect of the present invention, since the amount of heat generated by the motor changes according to the temperature detected by the temperature detecting means, the inside of the apparatus is always maintained at a substantially constant temperature. can do. Therefore, it is possible to prevent an operation trouble due to too warm or too cold, and to secure high reliability of the device.

According to the fourth aspect of the present invention, since the stepping motor is used as the motor, it is easy to switch between the transfer and the stop operation of the bill, and it is possible to ensure the transfer distance and the transfer speed. is there.

According to the fifth aspect of the present invention, since the motor is connected to a DC power supply of 10 to 30 V, it is safer than an AC 100 V power supply even if a leakage occurs. Further, since an external power supply is used, the weight of the apparatus can be reduced. Further, since the voltage is stable, the operation of the device is stable.
