Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to a banknote identification device equipped with an escrow device that stores banknotes once accepted in a state where they can be dispensed.

<Prior Art> In a banknote identification device, when a new banknote is inserted into an insertion slot while a banknote determined to be a genuine banknote is being drawn into an escrow device, this new banknote is normally
It is not desirable to accept the information as it is and then judge whether it is true or false. This is because if a newly inserted bill does not meet the genuine bill determination conditions, the bill transport motor must be reversed to automatically return the inserted bill. Even the previously inserted banknotes are returned to the entrance, causing unexpected trouble.

In order to prevent such problems from occurring, conventional banknote recognition devices are equipped with a shutter in the banknote insertion slot, and while the banknotes are being drawn into the escrow device, the shutter is closed to prevent the banknotes from being physically inserted. It was going to be impossible.

<Problems to be solved by the invention> However, the configuration in which the shutter and its control circuit are provided in the insertion slot complicates the structure of the banknote recognition device and is expensive, and it requires a large amount of time each time a banknote is stored in the escrow device. Close the shutter each time.
Since it had to be opened, there were also problems in terms of failure frequency and durability.

This idea was made in view of the above points,
It is an object of the present invention to provide a banknote identification device that can prohibit abnormal continuous insertion of banknotes by electrical control without relying on the shutter of the banknote slot.

<Means for solving the problem> The banknote identification device according to this invention includes a first sensor that detects that a banknote is inserted into a banknote insertion slot, and a banknote recognition device that detects a banknote based on the banknote detection by the first sensor. a conveying means capable of forward and reverse feeding that draws the banknote into the passage and conveys the banknote within the passage; and a conveying means that determines the authenticity of the banknote during the process of conveying the banknote within the passage and determines if the banknote is a counterfeit banknote. an escrow device capable of pulling in and holding genuine banknotes that have passed through the passageway and returning the held banknotes toward the passageway; In the middle of the first
a second sensor that is provided at a predetermined distance longer than the length of the banknote from the sensor and detects the banknote; and a second control means for causing the conveying means to reverse feed and return the banknotes when the first and second sensors simultaneously detect the banknotes before the operation of pulling genuine banknotes into the escrow device. control means, and when a banknote is detected by the first sensor while the first control means is performing an operation of pulling a genuine banknote into the escrow device, the drawing operation and the operation of the conveyance means. and third control means for temporarily interrupting the operation.

To show the correspondence with the embodiments described later, the first sensor is the sensor P _1R , P _1L , P _L , the conveying means is the banknote path 2 and the motor M1, and the determining means is each sensor P _1R ,
P _1L , _PL , P _X1 to P _X3 , magnetic detection head L _H , R
_H , C _H , the escrow device is the escrow device 9, the second sensor is the sensor _P2 (see above in Fig. 1), and the first control means is a control circuit that executes the routine from steps 16 to 28 in Fig. 3. , the second control means selects YES in step 18 and NO in step 19 in FIG.
A control circuit that executes a routine that goes to step 17 through
The control circuits generally correspond to the control circuits for executing the routines from 1 to 30 to 32, respectively.

<Operation> When the inserted bill is determined to be a genuine bill, the first control means controls to draw the inserted bill into the escrow device. If a banknote is simultaneously detected by the first and second sensors before this genuine banknote withdrawal operation is performed, the second control means
A banknote return operation is performed.

Since the interval between the first sensor and the second sensor is longer than the banknote length, both sensors detect the banknote at the same time, meaning that a new banknote enters the insertion slot while the inserted banknote is still in the middle of the banknote path. It means that the banknotes have been inserted (in other words, abnormal continuous banknotes have been inserted). Therefore, the second control means reverses the conveying means to remove the abnormally consecutively inserted banknotes.
Both copies will be returned. If additional banknotes are inserted during the retraction operation of genuine banknotes, this is the first
The third control means temporarily interrupts this retracting operation and the operation of the conveyance means. As a result, additionally inserted banknotes are not drawn into the interior through the insertion slot, and continuous insertion can be prohibited. In this case, the withdrawal of genuine banknotes that is in the middle of being withdrawn is temporarily interrupted, but the additionally inserted bills are
It will no longer be detected by the sensor. Once it is pulled out (for example by hand), the retraction operation by the first control means is continued and eventually it can be fed into the escrow device.

<Embodiment> An embodiment of this invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 schematically shows a side view of the banknote validating device, and FIG. 2 shows a banknote passage 2 of the device developed as viewed from the front. Bills inserted vertically from the entrance 1 are moved toward the passage 2 in the direction of arrow A by the forward rotation (clockwise rotation in the figure) of the motor M1.
Go inside. That is, as the motor M1 is driven to rotate normally, the belt 5 engaged with the motor M1 and the rollers 3 and 4 moves in the direction of arrow A, and the banknotes are conveyed accordingly. The figure particularly shows examples of the arrangement of various sensors. In FIG. 2, P _1L , P _1R ,
P _L , P _X1 , P _X2 , P _X3 , P ₂ , P ₃ and P ₄ are optical sensors, and CH, LH and RH are magnetic detection heads. As is clear from the side view of FIG.
(Signals 6 and 7 are given for P _L as an example).

Two sets of optical sensors P _1L and P _1R arranged near the entrance 1 at an interval corresponding to the width of the banknote and at the same position in the banknote transport direction are for determining the width of the inserted banknote. be. Two sets of optical sensors P _L , _P
2 is for determining the length of the banknote in the vertical direction. The above optical sensor P _X2 and this sensor P _X2
On the other hand, optical sensors P _X1 and P _X3 , which are arranged at a predetermined interval in the transport direction and arranged at a predetermined interval from each other in the lateral direction, are for determining the amount of light transmitted through the banknote. Magnetic detection head located at a position slightly offset from the center of passage 2
The magnetic detection heads LH and RH, which are arranged at a predetermined distance from CH and this head CH in the conveying direction and at a predetermined distance from each other in the lateral direction, detect magnetic components contained in the printing ink of banknotes. (iron, etc.). These sensors inspect the banknote's width, vertical length, translucency, and magnetic component distribution, and when all these properties satisfy the characteristics of a genuine banknote, the inserted banknote is accepted. If even one bill does not satisfy the properties of a genuine bill, the motor M1 is driven in reverse to return the bill in the passage 2 to the entrance 1. Furthermore, the sensors P _L , P _X
2. The reason why the CH is placed somewhat off center is that the center of banknotes often has a crease, and the crease is often thinner than the rest. This is to avoid this part during the inspection.

A gate lever 8 provided after the sensors for inspecting banknotes controls whether or not banknotes once accepted as genuine banknotes can be returned.
Lever 8 is normally equipped with a light spring (not shown)
It protrudes into the passageway 2 as shown by the solid line in FIG.
As shown in , the banknotes escape to the outside of the passage, allowing the banknotes to pass in the receiving direction A. However, if a banknote that has once passed the lever 8 returns back through the lever 8, the lever 8 is locked.
Block the banknote. However, when returning the banknotes normally, solenoid SOL1 is energized and lever 8 is activated.
is attracted to the position indicated by the dashed dotted line 8', and in the opposite direction (arrow A
(in the opposite direction). A switch SW1 provided in association with the lever 8 is turned off when the lever 8 protrudes into the passage 2, and turned on when the lever 8 escapes from the passage as shown by a dashed line 8'.

If the passageway 2 is functionally divided, it can be divided into a passageway section before the lever 8 for inspecting banknotes, and a passageway section after the lever 8 for accepting bills identified as genuine coins. The length of the latter passage section,
In other words, the length from point a immediately behind the lever 8 to point b at the end of the passage 2 corresponds to the length of the banknote in the vertical direction, for example. An escrow device 9 is provided downstream of the passage 2. This escrow device 9 has a function of temporarily holding the inserted banknotes and returning the held banknotes to the passage 2 if necessary. An optical sensor P ₃ provided at the exit of the passage 2 and an optical sensor P ₄ provided at the entrance of the escrow device 9
is used to control the motor M1 and the banknote winding motor M2 in the escrow device 9. In addition, an optical sensor P ₂ provided in front of the optical sensor P ₃
is for prohibiting the insertion of new banknotes when there are banknotes in the passageway 2.

In the escrow device 9, one end of a helical spring 11 is fixed to a predetermined location of a drum 10 that is rotated by a motor M2.
A banknote is placed between a winding body having a core and a spring 11.
and roll up the banknote tightly. That is, passage 2
The banknotes that entered the escrow device 9 from the exit of
It enters between the spring 11 and the winding body with the drum 10 as the core. As will be described later, the motor M2 is driven to rotate normally (counterclockwise in the figure) at appropriate times to wind the spring 11 around the drum 10, and together with the spring 11, the bill that has entered in the direction of arrow B is tightly wound. As an example, the drum 10 can wind up to about 40 banknotes. That is, the total length of the helical spring 11 is long enough to wind up about 40 banknotes. When returning the banknotes wound on the drum 10 to the path 2, the motor M2 is reversed. Spring 11 increases by the amount that motor M2 reverses.
is wound around the winding core 11a by self-righting force,
With the movement of the drum 10 and the spring 11, the bill is sent out in the opposite direction to the arrow B and returned to the passage 2.

A stocker 12 can be added to the escrow device 9 as a related option. The stocker 12 has the function of stacking and storing a large amount of banknotes. Solenoid SOL2 is drum 10
This is for directing the discharged banknotes toward the stocker 12, and the member 13 pushes the spring 11 due to the bias of SOL2, changing the flow of the discharged banknotes in the direction of arrow D. The optical sensor P ₅ provided in the stocker 12 is for detecting that banknotes are sent from the escrow device 9 to the stocker 12 through the flow of arrow D. Based on this detection, the banknote stacking operation in the stocker 12 is performed. Execute.

In addition, at each predetermined location (the locations are not particularly shown) in the escrow device 9, there is an escrow full detection switch SW2 and an escrow empty detection switch SW2.
3. Inventory switches SW4 are provided respectively. Further, a safety switch SW5 is provided at a predetermined location within the banknote identification device in relation to the escrow device 9. These switches will be described later.

Next, with reference to FIG. 3, processing and control procedures in the banknote identification device of FIG. 1 will be explained.

In step 14, the width sensor P _1L or P
_1R (may be limited to only one of them) to determine whether or not a banknote is detected. When a banknote is inserted through the entrance 1, the sensors P _1L and P _1R produce a banknote detection output, and step 14 becomes YES. Based on this insertion of the banknote, normal rotation of the motor M1 is started (step 15), and the banknote is drawn into the passage 2.
As mentioned above, in the process of the bill passing through the passage 2 in front of the gate lever 8, the optical sensors P _1R , P _1L , _PL ,
P _X1 , P _X2 , P _X3 and magnetic detection heads CH, RH,
The LH performs authenticity determination regarding the banknote's width, magnetic component distribution, amount of transmitted light, vertical length, etc. (step 16). In the authenticity determination in step 16, if it is detected that the conditions for a genuine bill are not met, the motor M1 is immediately reversed at the time of detection to convey the bill in the opposite direction of arrow A and return it (step 17). ). If it is determined that the bill satisfies the conditions for a genuine note in all respects, the process proceeds to step 18. In that case, normal rotation of motor M1 continues.

At step 18, sensor _P2 detects a banknote. (P ₂ on). Sensor P ₂
is _{a position} such that when the trailing edge of the bill passes the last sensor P _X1 , P It is arranged in Therefore, the answer to step 18 following step 16 is normally YES, but if it is NO, there is an abnormality and the process proceeds to step 17, where the inserted banknotes are returned. Sensor _P2 and step 19 are involved to inhibit continuous insertion of banknotes. In step 19, sensors P _1L ,
Either P _1R or P _L detects a banknote (P _1
L , _P1R or P _L on). still,
The distance between the sensors P _1L , P _1R , _PL and P ₂ is longer than the length of the banknote. If bills are not inserted continuously,
Step 19 is NO, and the process proceeds to step 20. In the case of continuous insertion, when the previous banknote determined to be genuine is detected by sensor P ₂ , the subsequent banknote is detected by any of sensors P _1R , P _1L , and _PL . Therefore, step 19 is
YES, move to step 17, and motor M1
is reversed to return the subsequent banknotes and the banknotes detected by sensor _P2 . At this stage, the banknotes detected by sensor _P2 have not yet passed through the gate lever 8, so reverse feeding is possible, and the banknotes determined to be genuine banknotes are still being counted. Since it is not, there is no inconvenience in returning it〓〓〓〓〓
Does not occur.

By the way, when the banknotes being conveyed through the passage 2 push the gate lever 8 away to the position indicated by the one-dot chain line 8', the switch SW1 is turned on. Eventually, when the rear end of the banknote finishes passing through the lever 8, the lever 8 returns to the inside of the passage 2, and the switch SW1 is turned off. In this way, the banknotes are not returned midway and the switch SW
1 changes from ON to OFF, this indicates that a banknote determined to be a genuine banknote has been accepted into the passage 2 downstream of the gate lever 8. At this time, the rear end of the accepted banknote is located approximately at point a (Fig. 1),
The front end is located approximately at point b. In this position, the gate lever 8 prevents the banknote from returning in the return direction (in the direction opposite to arrow A). In other words, when the switch SW1 changes from on to off without the banknote being returned halfway, the genuine note signal ALL OK is generated, and the counting control device (not shown) generates the signal ALL.
Since the system is designed to count OKs and remember that a single genuine bill has been accepted, once a bill has been accepted as a genuine bill, it is prevented from being returned without authorization unless there is a predetermined return order.

An example of the output of the sensors P _1L and P _1R is shown in FIG. 4a, and an example of the output of the switch SW1 is shown in FIG. 4b. An example of the ALL OK signal is shown in FIG. 4c. In Figure 4, when the sensor detects a banknote,
Alternatively, a high level indicates when a switch, motor, or timer is turned on, or when a signal is generated.

Returning to the explanation of FIG. 3, in step 20 it is determined whether the switch SW1 has changed from on to off. If YES, authentic bill signal is sent in step 21.
Set ALL OK and proceed to step 22.
Although a reset step is not particularly shown, the authentic bill signal ALL OK is reset after a predetermined period of time. In step 22, the motor M1 is stopped, the motor M2 is started to rotate in the normal direction, and the timer TM is started. By the process from step 22 onwards in FIG. 3, the process of drawing the banknotes received into the passage 2 (from point a to point b) downstream of the gate lever 8 into the escrow device 9 is executed.

The rear end of the bill that was previously drawn into the escrow device 9 is located at the location where it passed through the sensor _P4 , that is, at point c in FIG. On the other hand, step 21
At the time of processing, the leading edge of the banknote in the passage 2 is at point b. Since the speeds of motors M1 and M2 are different,
If both motors M1 and M2 are rotated together, there is a risk that the currently inserted banknotes will overlap with the banknotes in the escrow device 9. In order to eliminate such inconvenience, the motor M1 is temporarily stopped in step 22, and the motor M2 is rotated first. Therefore, by the independent drive of the motor M2, the previously inserted bill whose rear end was at point c is further wound around the drum 10, while the leading edge of the currently inserted bill in the passage 2 is stopped at point b. The operating time of the timer TM is determined by the motor M in view of the above reasons.
This is an appropriate time for temporarily stopping motor M1, and an example is about 200ms (in this case, motor M1
It is assumed that the bill feeding speed is approximately 64 mm per second).

In step 23, it is determined whether the predetermined operating time of the timer TM has expired. When the operating time of the timer TM ends, in step 24, normal rotation of the motor M1 is started. Thus motor M
1 and M2 rotate together, and banknotes in the passage 2 are fed into the escrow device 9 by the rotation of the motor M1 and drawn into the escrow device 9 by the rotation of the motor M2. Motor M1,
The states of M2 and timer TM are shown in FIGS. 4d, e, and f. In response to the withdrawal of banknotes into the escrow device 9, the outputs of the sensors _P3 and _P4 change as shown in FIG. 4g and h. That is, from the time the leading edge of the bill enters the sensors P ₃ and P ₄ , the trailing edge enters the sensor P 3 and P 4 .
₃ and P ₄ are shown at a high level in g and h of the figure.

When the state of sensor _P3 changes from high level to low level, that is, when the trailing edge of the banknote
₃ , motor M1 is stopped as shown in FIG. 4d. This process is shown in steps 25 and 26 of FIG. Further, when the state of sensor _P4 changes from high level to low level, that is, when the rear end of the banknote passes past sensor _P4 , motor M2 is stopped as shown in FIG. 4e. This process is illustrated in steps 27 and 28 of FIG. In this way, when the rear end of the banknote is located at point c in FIG. 1, the drawing of the banknote into the escrow device 9 is completed.

While drawing banknotes into the escrow device 9,
〓〓〓〓〓
That is, if a new banknote is inserted into the entrance 1 while the motors M1 and M2 are being driven in normal rotation at the same time, the motors M1 and M2 are stopped and the drawing of the received banknote into the escrow device 9 is temporarily interrupted. It is prohibited to draw new banknotes into the passage 2.
That is, when the sensor P _1L or P _1R generates a banknote detection output as shown by the broken line in FIG. 4a during normal rotation of M1 and M2, the motors M1 and M2 are activated as shown by the broken line in FIG. 4d and e. Pause. When the banknotes at the entrance 1 are removed, the banknote detection signals from the sensors P _1L and P _1R disappear, and the normal rotation of the motors M1 and M2 is resumed. This process is performed in steps 29, 30, and 3 in FIG.
1,32.

In step 29, sensor P _1L or P
Determine whether _1R detects a banknote (P _1L or P _1R on). If NO, the process proceeds to step 25, where it is determined whether the bill has finished passing through sensor _P3 ( _P3 off). If NO, that is, if sensor _P3 is still detecting a banknote, the process returns to step 29. If a new banknote is inserted into the entrance 1 while the banknote is being drawn into the escrow device 9,
Step 29 becomes YES, and the process advances to step 30 to stop motors M1 and M2. This prohibits the acceptance of new banknotes. Next step 3
In step 1, it is determined whether or not both sensors P _1L and P _1R no longer detect banknotes (P _1L and P _1R off). When the user, who learned that he was not allowed to insert additional banknotes, pulled out a new banknote from entrance 1,
Step 31 becomes YES, and the process proceeds to step 32, where normal rotation of motors M1 and M2 is resumed.

After step 32, the process moves to step 25. The rear end of the banknote drawn into the escrow device 9 is connected to the sensor P ₃
When it passes, step 25 becomes YES,
At step 26, motor M1 is stopped. Next, the process proceeds to step 27, where it is determined whether the rear end of the banknote has passed the sensor _P4 ( _P4 off), and if YES, the motor M2 is stopped at step 28.

Note that the banknote withdrawal operation into the escrow device 9 is faster than manual operation, so the banknote withdrawal operation into the escrow device 9 can be performed until the rejected subsequent banknotes are manually pulled back from the entrance 1 and then reinserted. Normally, the banknotes that have been rejected can be accepted the second time without any problems.

When returning banknotes once received into the escrow device 9 due to cancellation or settlement, the process is performed according to the procedure shown in FIG. First, when a refund command is given, the solenoid SOL1 is energized and the gate lever 8 is moved out of the passage 2. Next, the motor M1 starts to rotate in reverse, and after a short waiting time is set, the motor M2 starts to rotate in the reverse direction. Thereby, the banknotes are discharged from the escrow device 9 toward the passage 2.
Once sensor P ₄ detects a banknote (“P ₄ on”)
YES), then when the banknotes are no longer detected (“P ₄ OFF” YES), one banknote is transferred to the escrow machine 9.
This means that it has been completely sent out to passage 2. At that time, motor M2 is stopped. Motor M1
continues to reverse, so one bill in the passage 2 is conveyed in the opposite direction to the arrow A and discharged from the entrance 1. When the sensors P _1L and P _1R once detect a banknote (“P _1L and P _1R on” YES) and then no longer detect a banknote (“P _1L and P _1R off” YES),
This means that one bill has been completely ejected from the entrance 1. At that time, motor M1 is stopped, solenoid SOL1 is deenergized, and lever 8 is moved to passage 2.
Bring it back inside. One bill is refunded in the above manner. By providing a counting means for counting the number of ejected bills and repeating the process shown in FIG. 5, an arbitrary number of bills can be refunded from the escrow device 9.

The escrow device 9 is equipped with a mechanism (not shown) that transmits the rotation of the motor M2 by gearing down, and in relation to this mechanism, an escrow full detection switch SW2 and an escrow empty detection switch SW3 are installed at predetermined locations. It is provided. When the motor M2 is in the initial position, that is, the drum 10
When no banknotes are wound up at all, the empty detection switch SW3 is activated to detect the empty state. When the motor M2 rotates a predetermined amount in the forward direction from the initial position (for example, when about 40 banknotes have been wound up), the full detection switch SW2, which is provided in connection with the gear down mechanism, operates and detects that the motor is full. To detect. When fullness is detected by this switch SW2, driving of the motor M2 is prohibited, and driving of the motor M1 of the main body is also prohibited.

As an example, the escrow device 9 includes a banknote identification device main body 33 including an entrance 1, a passage 2, a motor M1, etc.
(See Figure 6), and the safety switch SW5 can be removed from the main body 33.
It is provided at a predetermined location on the main body 33 to detect that it has been removed. For example, the escrow device 9 can be tilted at a predetermined angle about the shaft 9a as a fulcrum as shown by the two-dot chain line in FIG. 6, and then pulled in the direction of arrow E.
3, and the safety switch SW5 is activated when the escrow device 9 is separated from the main body 33 in this way.
(mainly the driving of motor M1). This is because if the escrow device 9 is detached, banknotes cannot be accepted, and in such a case, the operation of the banknote identification device is prohibited.

The inventory switch SW4 is operated when all banknotes stored in the escrow device 9 are discharged and collected. When the administrator tilts the escrow device 9 as shown by the two-dot chain line in FIG. 6 and operates the inventory switch SW4,
The motor M2 rotates in reverse and all the banknotes wound on the drum 10 are discharged from the outlet (inlet) where the sensor _P4 is provided. The administrator only has to manually receive and collect the discharged banknotes. At this time, the sensor P ₄ detects the bill, but does not exert any control on the main body 33 . This is because the operation of the main body 33 is prohibited by the operation of the safety switch SW5. Inventory switch SW
When the empty detection switch SW3 detects an empty state during the operation of step 4, the motor M2 is controlled to automatically stop.

In the above embodiments, the control circuit has been described as being configured by software processing, but it is of course possible to configure it by hard logic as well. Further, the motors M1 and M2 may be stopped when a bill is detected by the sensors P _1L and P _1R on the condition that both or one of the sensors P ₃ and P ₄ is detecting a bill. Further, the sensor for detecting banknotes is not limited to an optical sensor, and may be any sensor that can detect the passage of banknotes.

<Effects of the invention> As explained above, according to this invention, the first sensor (P _1R , P _1L or P _L ) and the second
When the _first sensor (P _1L , When a banknote is detected at _P1R ), continuous insertion of banknotes is prohibited by temporarily interrupting the retracting operation and the operation of the conveying means (normal rotation of motors M1 and M2), so the shutter at the entrance is This is not necessary, and the structure is simplified, economical, and durable.
