Banknotes that cannot be identified by the identification unit 10 are transported to the withdrawal reject storage 18a.

(Forgotten collection process)
In FIG. 9, the banknotes collectively paid out at the withdrawal port 4 are held at the withdrawal port 4 in a withdrawal standby state. If the banknotes in this state are not removed for a certain period of time, the banknotes are transported to the forgotten collection box 18c and collected. If the number of banknotes that cannot be extracted is 21 or more, those banknotes are transported to the withdrawal unit 5 and collected. Then, after the collection, the operation of the banknote processing device 1 is stopped as if an error has occurred.

<Structure and operation of deposit slot 2 and deposit unit 3>
Hereinafter, the deposit opening 2 and the deposit unit 3 in the bill processing apparatus 1 will be further described.
(Overall composition)
FIG. 10 shows an enlarged view of the deposit opening 2 and the deposit portion 3 in FIG. As shown in FIG. 12, the deposit opening 2 has a width M into which a bill F, which is a paper leaf, can be inserted. In FIG. 10, the deposit unit 3 is provided at a shutter 60 that opens and closes the bill passage N, a first transport unit 61 as a take-in transport means provided at a downstream position of the shutter 60, and a downstream position of the first transport unit 61. A second transport unit 62 as a take-in transport means, a kick roller 63 provided at a downstream position of the second transport unit 62, a bill holder 64 provided facing the kick roller 63, and a bill holder 64. It has a stopper 67 arranged at a downstream position, a feeding roller 68 provided at a downstream position of the kick roller 63, and a regulating roller 69 provided facing the feeding roller 68.

The first transport section 61, the second transport section 62, the kick roller 63, and the feeding roller 68 are all provided at positions below the bill passage N. The bill retainer 64, the stopper 67, and the regulation roller 69 are all provided above the bill passage N. A foreign matter receiver 70 is provided at a position below the second transport portion 62, the kick roller 63, and the feeding roller 68.

(1st transport unit)
The first transport unit 61 has a transport belt 74 spanned between the drive roller 72 and the driven roller 73. The transport belt 74 is driven by the drive roller 72 and orbits in the clockwise direction or the counterclockwise direction in FIG. In the present specification, the rotation or the orbital movement in the clockwise direction of the rotating member or the orbiting moving member located below the banknote passage N is referred to as "forward rotation", and the rotating member or the orbiting moving member located below the banknote passage N is referred to as "forward rotation". The counterclockwise rotation or orbital movement of is sometimes called "reversal". From this point onward, the direction of movement of the banknote along the banknote passage N may be referred to as the banknote transport direction V.

(2nd transport section)
The second transport unit 62 has a transport belt 77 spanned by the drive roller 75 and the driven roller 76. The transport belt 77 is driven by a drive roller 75 to perform forward rotation or reverse rotation. As for the transport belt 74 of the first transport unit 61 and the transport belt 77 of the second transport unit 62, as shown in FIG. 12, two transport belts are parallel to each other at right angles to the bill passage N. It is provided. The bill F is conveyed on both sides on the longitudinal side by these transport belts. As shown in FIG. 10, a gap 66a for dropping a small foreign substance is provided between the first transport unit 61 and the second transport unit 62.

(Upper transport roller 81)
An upper transfer roller 81 is provided so as to face the driven roller 73 of the first transfer unit 61. The upper transfer roller 81 is a driven roller, and is connected to the drive roller 80 by a transfer belt 82. Further, the upper transfer roller 81 has a structure in which a contact portion is formed in which an urging force is applied to the driven roller 73 of the opposite first transfer portion 61. A carrying force is applied by sandwiching the bill sent to the contact portion. That is, the portion where the transport belt 74 and the upper transport roller 81 come into contact with each other is the holding force imparting point X. When the transport belt 74 makes a forward rotation orbit, the banknotes are sent to the inside of the deposit unit 3. The upper transfer roller 81 includes an impeller 87. The impeller 87 aligns the bundle of banknotes by intermittently tapping the rear end of the bundle of banknotes. When the transport belt 74 makes a reverse orbital movement, the bill is returned to the deposit opening 2.

(Kick roller 63 and bill holder 64)
The kick roller 63 can rotate in the forward direction at a predetermined rotation speed. Further, the kick roller 63 can move forward and backward as shown by an arrow p between an overhanging position that contacts a bill moving on the bill passage N and a retracting position that retracts from the bill passage N. The bill retainer 64 rotates about a shaft member 78 as shown by an arrow r between an overhanging position that contacts a bill moving on the bill passage N and a retracting position that retracts from the bill passage N. You can move forward and backward with respect to the transport passage N. The bill holder 64 is provided with a freely rotating roller at the tip. The bill retainer 64 presses a bundle of bills against the kick roller 63. When the kick roller 63 sends out one bill, the roller at the tip of the bill retainer 64 is rotated around the kick roller 63.

When the kick roller 63 and the bill holder 64 are both in the position of extending to the bill passage N, if a bundle of bills arrives at both places, the upper portion of the bundle is pressed by the bill holder 64, so that in principle. The lowest-ranked banknote is conveyed between the feed roller 68 and the regulation roller 96 by the kick roller 63. For the last bill, the free-rotating roller at the tip of the bill retainer 64 rotates to convey the last bill. Reference numeral 65 indicates an electromagnetic solenoid that is a power source for driving the bill holder 64. When the transport belt 74 of the first transport unit 61 and the transport belt 77 of the second transport unit 62 shift from the forward rotation to the reverse rotation, the bill retainer 64 and the kick roller 63 retract and move to a position away from the bill passage N.

(Stopper 67)
As shown by the arrow T, the stopper 67 can rotate about the shaft member 78 between the overhanging position that blocks the bill passage N and the separated position away from the bill passage N. The stopper 67 at the overhang position prevents the bill from moving along the bill passage N. The stopper 67 at the separated position allows the movement of banknotes. The distance D1 between the position where the upper transport roller 81 abuts on the transport belt 74 of the first transport portion 61 (that is, the point X where the holding force is applied) and the stopper 67 overhanging at the position where the bill transport path is shielded is set. It is set to a distance obtained by adding a predetermined margin (that is, a margin length) to the length of the maximum bill to be processed.

(Feeding roller 68 and regulation roller 69)
The ejection roller 68 and the regulation roller 69 are in contact with each other or in close proximity to each other in the banknote passage N so that one banknote can be passed through. The feeding roller 68 can rotate in the forward direction at a predetermined rotation speed. The regulation roller 69 can preferably perform rotations that regulate the payout of overlapping banknotes. Alternatively, the regulation roller 69 can adopt a structure in which the regulation roller 69 does not rotate in the bill transport direction V but freely rotates only in the direction opposite to the bill transport direction V. As a result, when a plurality of banknotes arrive at both places in a state of being overlapped with each other, only the lower one of the bundles in contact with the feeding roller 68 is separated from the bundle by the feeding roller 68 and sent out to the rear stage side. The feeding roller 68 and the regulating roller 69 also regulate the intrusion of thick foreign matter into the inside of the paper leaf processing apparatus.

(Thickness detection sensor 83)
In FIG. 10, the upper transfer roller 81 moves in the vertical direction in the figure according to the thickness of the bundle of banknotes to be conveyed. FIG. 11 shows the structure on the back side, which is the opposite side of the structure on the front side of the deposit portion 3 shown in FIG. This is a structure constructed on the machine frame on the back surface opposite to the front side shown in FIG. 3, that is, the machine frame 27 on the left side surface of FIG. As shown in FIG. 11, a thickness detection sensor 83 is provided on the back side of the upper transfer roller 81 in FIG. 10. The thickness detection sensor 83 can read the vertical displacement of the object by a well-known mechanism (not shown). Such a thickness detection sensor detects the thickness of a bundle of banknotes.

(Drive structure)
An electric motor 84, which is a power source, is provided above the deposit unit 3. In FIG. 11, a drive timing belt 85 is hung on the output shaft 84a of the motor 84. The drive belt 85 is stretched over a wide area of the deposit portion 3 and serves as a power source for various operating devices shown in FIG. Reference numeral 86 in FIG. 11 indicates an electromagnetic solenoid for driving the stopper 67 and the kick roller 63 in FIG.

<Sensor placement>
(1st sensor)
In FIG. 10, first sensors 91a and 91b are provided at the boundary between the deposit opening 2 and the deposit portion 3. As shown in FIG. 12, these sensors 91a and 91b are provided on both the left and right sides of the deposit opening 2 or the deposit portion 3 in the width direction. The positions of these first sensors 91a and 91b along the bill transport direction V are the same as each other. The inserted banknotes and the like are first detected by this first sensor.

(2nd sensor)
In FIG. 10, the second sensor 92 is located between the position where the upper transport roller 81 abuts on the transport belt 74 of the first transport portion 61 (that is, the holding point X) and the first sensors 91a and 91b. It is provided. The second sensor 92 outputs a signal that serves as a reference when the control unit recognizes a medium having a short length (for example, a short ticket). As shown in FIG. 12, the second sensor 92 is arranged on a substantially center line in the width direction of the bill passage N, but may be provided at any point on the line orthogonal to the center line.

(Third sensor)
In FIG. 10, the third sensor 93 is provided at a position corresponding to the rear portion of the second transport portion 62. As shown in FIG. 12, the third sensor 93 has a second so that the rear end portion of the bill F0 having a normal length L0 is shielded from light by the front end portion of the normal bill F0 when the second sensor 92 is shielded from light. It is arranged with a distance D2 with respect to the sensor 92. The third sensor 93 is arranged slightly to the left of the center line in the width direction of the banknote passage N when viewed from the upstream side of the banknote transport direction V, but is provided at an arbitrary point on the line orthogonal to the center line. Is also good.

(4th sensor)
In FIG. 10, two fourth sensors 94a and 94b are provided on the downstream side of the third sensor 93 and at a position immediately before the bill holder 64. As shown in FIG. 12, the fourth sensors 94a and 94b are provided on both the left and right sides of the center line in the width direction of the transport passage N. The fourth sensors 94a and 94b are provided in the vicinity of the rear end of the transport belt 77 of the second transport unit 62.

(Fifth sensor)
In FIG. 10, a fifth sensor 95 is provided between the second sensor 92 and the third sensor 93. As shown in FIG. 12, the fifth sensor 95 is arranged on the center line in the width direction of the bill passage N, but may be provided at any point on the line orthogonal to the center line.

(6th sensor)
In FIG. 10, a sixth sensor 96 is provided between the fifth sensor 95 and the third sensor 93. As shown in FIG. 12, the sixth sensor 96 is arranged slightly to the left of the center line in the width direction of the banknote passage N when viewed from the upstream side of the banknote transport direction V, but is on a line orthogonal to the center line. It may be provided at any point.

(7th sensor)
In FIG. 10, three seventh sensors 97a, 97b, 97c are provided immediately after the feeding roller 68 and the regulating roller 69. As shown in FIG. 12, the seventh sensors 97a, 97b, 97c are provided on the center line of the bill passage N and on the left and right sides of the center line.

In this embodiment, the sensors of the first sensor 91a, 91b, the second sensor 92, the third sensor 93, the fourth sensor 94a, 94b, the fifth sensor 95, the sixth sensor 96, and the seventh sensor 97a, 97b, 97c are each. Is composed of a photoelectric sensor. When there is no banknote to be detected in the detection area of these sensors, the sensor light is not shielded (that is, translucent), so that the sensor does not detect the banknote. On the other hand, when a bill arrives at these sensors, the sensor light is shielded, so that the sensor detects the bill. In the present specification, the fact that the sensor detects a banknote is expressed as "ON" of the sensor, and the fact that the sensor does not detect the banknote is expressed as "OFF" of the sensor.

The ON signal and OFF signal of each sensor are transmitted to a control unit provided at an appropriate position in the paper sheet processing apparatus. The control unit controls the operation of various devices shown in FIGS. 10 and 11 based on these signals. The sensor is not limited to the photoelectric sensor. For example, it can be replaced with a magnetic sensor, a mechanical switch, or any other sensor.

<Operation of deposit slot 2 and deposit section 3>
In FIG. 10, the bill F is inserted by the user through the deposit opening 2. In this embodiment, a bundle of up to 50 banknotes can be inserted. When the inserted banknote F is a normal banknote, the left and right first sensors 91a and 91b in the width direction are turned on at the same time in FIG. When these sensors 10a and 10b are not turned on at the same time, the control unit determines that a single foreign object having a short width has been inserted. At this time, the control unit keeps the shutter 60 provided at the head position of the deposit unit 3 in FIG. 10 closed (as in the initial state). This prevents the insertion of foreign matter with a short width.

When the first sensors 91a and 91b detect a bill that is normal in terms of width, the control unit opens the shutter and further orbits the first transport unit 61 and the second transport unit 62 in the forward rotation direction. As a result, the bill F is taken into the deposit unit 3. At this time, both the kick roller 63 and the bill holder 64 are separated from each other with respect to the bill passage N. Therefore, the transporting force to the banknote is applied from the first transporting unit 61 and the second transporting unit 62. After that, when the second sensor 92 detects the bill and turns ON, the control unit determines the number of bills based on the output signal of the thickness detection sensor 83. That is, the output signal of the second sensor 92 serves as a reference for the operation of the thickness detection sensor 83.

(Two or more bundled banknotes)
When the thickness detection sensor 83 determines that the number of banknotes is two or more, the control unit sets the stopper 67 to the shielding position (lower position shown by the chain line in FIG. 10). This shielding position is a position where the stopper 67 prevents the bill from advancing along the bill passage N. At the same time, the control unit separates the bill holder 64 and the kick roller 63 from the bill passage N. As a result, the banknote retainer 64 does not press the upper surface of the bundled banknotes. In this state, the tips of a bundle of a plurality of banknotes abut against the stopper 67.

(1 banknote)
When the control unit determines that one banknote has been inserted based on the output signal of the thickness detection sensor 83, the control unit further sets the banknote holder 64 and the kick roller 63 to the banknote without setting the stopper 67 in the shielding position. The following control is performed based on the output signal of each sensor in FIG. 10 while keeping the distance from the passage N.

(When a normal banknote is inserted)
In FIG. 12, when a normal bill F0 having a normal length L0 is inserted into the deposit slot 2, the first sensors 91a and 91b are first turned from OFF to ON. When the bill F0 further advances and its trailing end passes through the first sensors 91a and 91b, the first sensors 91a and 91b are turned from ON to OFF. If the length L0 of the bill F0 is normal, when the first sensor 91 is turned off, all of the fifth sensor 95, the sixth sensor 96, and the third sensor 93 are turned on. As a result, the control unit determines that the bill F0 is a normal bill.

(Short medium, short foreign object, short ticket)
In FIG. 14, when the medium F1 having a length L1 shorter than the normal length is inserted from the deposit opening 2, the second sensor 92 first turns from OFF to ON as the tip of the medium F1 passes. If the length L1 of the medium F1 is shorter than normal, the third sensor 93 does not turn ON (that is, remains OFF) when the second sensor 92 turns from ON to OFF as the rear end of the medium F1 passes. .. As a result, the control unit determines that the medium is a foreign substance that is not a normal banknote, reverses the transport belt 74 and the transport belt 77, and returns the foreign substance to the deposit slot 2.

When the length of the medium F1 is even shorter than that of L1, the sixth sensor 96 may remain OFF, or the fifth sensor 95 may remain OFF. That is, the second sensor 92, the fifth sensor 95, and the sixth sensor 96 are utilized for detecting a very short foreign object or a very short short ticket. Even when the medium is a short foreign matter, the transport belt 74 and the transport belt 77 are reversed and the foreign matter is returned to the deposit port 2. In this embodiment, the third sensor 93, the fifth sensor 95, and the sixth sensor 96 are installed so that those having a length of 124 mm or less are recognized as "short ticket", "foreign matter", and "short medium". The position is set.

(Long medium, long foreign object, long ticket)
In FIG. 13, when the medium F2 having a length L2 longer than the normal length is inserted from the deposit port 2, the output signals of the first sensors 91a and 91b are also turned on when the output signals of the fourth sensors 94a and 94b are ON. It remains ON. In this case, the control unit determines that the foreign matter has been inserted, reverses the transport belt 77 of the second transport unit 62 and the transport belt 74 of the first transport unit 61, and returns the foreign matter to the deposit port 2. do. In the present embodiment, the installation positions of the fourth sensors 94a and 94b are set so that those having a length exceeding 200 mm are recognized as "long ticket", "foreign matter", and "long medium".

(Thin medium)
Similar to the processed banknotes, the medium with the thickness or less and the size recognized as a foreign substance is shifted to the predetermined processing for being taken into the apparatus. If the medium taken in in this way is a foreign substance, the identification unit 10 in FIG. 2 determines that the medium is a foreign substance, so that the medium is conveyed to the withdrawal port 4 and returned. Since this foreign matter is similar to a bill in the width direction, it can be said that there is almost no possibility of clogging at the transport portion.

(Thick medium)
When the thickness detection sensor 83 of FIG. 10 detects a medium thicker than the permissible range, the control unit reverses the transport belt 74 of the first transport unit 61 and returns the thick medium. The sixth sensor 96 and the third sensor 93 confirm that the thick medium that should be returned does not remain in the device. When these sensors detect the residual foreign matter, the control unit reverses the transport belt 74 of the first transport unit 61 and the transport belt 77 of the second transport unit 62, and returns the foreign matter.

(1st sensor and 4th sensor)
In FIG. 12, a plurality of first sensors 91a, 91b and fourth sensors 94a, 94b arranged near the outer edge of the sensor installation area can be provided along a direction orthogonal to the bill transport direction V. For example, when two sensors are provided as in the present embodiment, if the ON / OFF states of the four sensors are confirmed, the width is narrow and long, such as a receipt, or a bundle of banknotes. It is possible to detect various items such as those in which stacking is misaligned and those in which the corners of banknotes are broken and remain. In this case, if light transmission (that is, OFF) occurs even in one of the four sensors, the object can be returned by reversing the transport belt.

(Foreign matter receiver 70)
The non-returnable foreign matter is temporarily received by the foreign matter receiver 70 provided at the bottom in FIG. The foreign matter is, for example, a coin sandwiched between a plurality of bundles described later, and the foreign matter is removed from the device by the device manager as needed.

(Processing of multiple sheets)
In FIG. 10, when the thickness detection sensor 83 determines that the inserted medium has two or more sheets, that is, a plurality of sheets, the inserted medium is attached to the transfer belt 74 of the first transfer unit 61 and the upper transfer roller 81. Be pinched (ie pinched). The sandwiched medium moves toward the stopper 67 in the bill transport direction N at a predetermined speed. When the moving medium and the upper transfer roller 81 are separated from each other, the medium comes into contact with the stopper 67 in a free state without a load on the surface of the medium. Further, since the transport force for normal rotation is also applied by the transport belt 77 of the second transport portion 62 in the free state, the end portions of the medium on the ejection portion side are aligned by the stopper 67. Further, an impeller 87 is arranged on the upper transfer roller 81, and the impeller 87 acts on the end portion on the deposit port side of the medium to assist the alignment of the end portion on the ejection portion side of the medium. To. In this state, the transportation of the medium in the deposit unit 3 is temporarily stopped.

Next, the stopper 67 is retracted upward, and at the same time, the bill holder 64 is lowered and the kick roller 63 is raised. Next, the normal rotation transfer in the deposit unit 3 is restarted. As a result, the overlapping state of the bundled media sandwiched between the bill holder 64 and the kick roller 63 is given a variation, and the bundled media is sequentially transferred from the lower side to the contact portion between the feeding roller 68 and the regulation roller 69. Be transported. The conveyed banknotes are accurately separated one by one by the regulation roller 69 and the feeding roller 68, and are fed to the next stage.

Even in the above processing, foreign matter can be detected as follows based on the output signal of the sensor.
(1) When a thick foreign object is inserted:
In this case, at least one "thick foreign matter" is sent out by the regulation roller 69 and the feeding roller 68 and remains on the downstream side of those rollers. In that state, the bill holder 64 is raised and the kick roller 63 is lowered. By this operation, coins and the like in the portion close to the kick roller 63 also fall to the foreign matter receiver 70. Next, the control unit outputs light-shielding (that is, ON) of the fifth sensor 95, the sixth sensor 96, the third sensor 93, the fourth sensor 94a, 94b, and the seventh sensor 97a, 97b, 97c in FIG. confirm. Normally, all sensors are translucent (that is, OFF), but if a thick card or the like remains without being drawn out, the sensor corresponding to the residual position outputs ON. In this case, the transport belts 74 and 77 in the first transport section 61 and the second transport section 62 in FIG. 10 are reversed, and the foreign matter that is the cause of the ON output is returned to the deposit port 2.

(2) When a piece of paper such as a receipt with no thickness is inserted:
This piece of paper is indistinguishable from the one in which the bill was inserted with the bill shifted in the length direction. Therefore, first, the upper transport roller 81 of FIG. 10 is rotated in the bill taking direction for a predetermined time. If the output signals of the first sensors 91a and 91b remain ON when the output signals of the fourth sensors 94a and 94b in FIG. 13 are ON during the rotation for a predetermined time, it is determined that the piece of paper is a long foreign substance. The transport belts 74 and 77 of the first transport section 61 and the second transport section 62 in FIG. 10 are reversed, and the paper piece is returned to the deposit slot 2.

(3) In the above description, "thin and long receipts", "thick cards" and the like are exemplified as foreign substances. In addition to these, small foreign substances such as "clips" and "buttons" can be considered as foreign substances. For this small foreign matter, as shown in FIG. 10, an appropriate gap 66a may be provided between the first transport unit 61 and the second transport unit 62, or a pair of transport belts 74 in the first transport unit 61 may be provided. A gap 66b is provided between the two, as shown in FIG. 12, and a gap 66c is provided between the pair of transport belts 77 in the second transport portion 62, as shown in FIG. It can be collected by dropping it on the receiver 70.

(Action and effect of this embodiment)
In this embodiment,
(1) In FIG. 12, the first sensors 91a and 91b detect a narrow foreign object, and the shutter 60 blocks the supply into the apparatus. also,
(2) In FIG. 13, a long foreign matter was detected by the first sensors 91a and 91b and the fourth sensors 94a and 94b, and the supply of the foreign matter into the device was blocked by the reversal of the transport belts 74 and 77. also,
(3) A short foreign substance was detected by the second sensor 92, the fifth sensor 95, the sixth sensor 96, and the third sensor 93, and the supply of the foreign substance into the device was blocked by reversing the conveyor belts 74 and 77. also,
(4) The thickness detection sensor 83 detects whether the inserted medium is one sheet or a bundle (two or more sheets), and when the medium is a bundle, the operation of the bill holder 64, the kick roller 63, and the stopper 67 is controlled to control the end edge of the bundle. Align. Then, we decided to perform detection by the sensor in this aligned state. This makes it possible to accurately determine whether the bundle of media is a "normal banknote", a "long foreign object", or a "short foreign object".
