Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet transfer apparatus capable of adjusting the arrival time and direction of a sheet.

[Conventional technology]

The present invention has one application to a bill feeding mechanism used in a cash dispenser of an automatic teller machine (ATM). During the operation of the ATM, the user inserts an identification card into the machine and then inputs certain data (code, amount and type of transaction) from the keyboard. The machine processes the transaction, updates the user's account, withdraws the amount from the machine's bill cassette in the case of a withdrawal, and returns the card to the user to complete the normal transaction process.

ATM cash dispensers usually have at least one pick mechanism to extract bills one by one from a bill cassette, and a stack and submission mechanism to accumulate the bills that have been drawn into the stack, and a user to take out a bill bundle. And a mechanism for sending out a bundle of bills to a payout port that can make the bills.

Known banknote stacking mechanisms have a group of curved teeth and have a continuously rotating stacking wheel. The bills are sent one by one to a stacking wheel and successively enter adjacent spaces. The banknotes entering the vacant space rotate at least partially about the axis of the stacking wheel and are removed therefrom by a fixed removal member to form a stack or a bundle.

The bill picking means and the stacking wheel are synchronized, and normally operated bills are continuously put into the empty space of the stacking wheel. However, for example, when the leading edge of the bill is broken, the bill may hit the teeth without entering the space correctly, not being paid correctly, and the bill may be jammed in the mechanism. There is a disadvantage that. In addition, when the bill picking means uses the friction feeding means, there is a possibility that a slip may occur between the bill and the feed mechanism under certain circumstances, and the bill may hit the teeth.

The present invention has application to banknote verification. Some banknote verification systems include sensing means for generating a signal in response to recognition of the feature or absence of the feature of the banknote and comparing it to a standard signal. In order for the system to work properly, the bill must be oriented correctly with respect to the detection means. UK Patent Application No. 2128169A discloses a method for removing the skew of banknotes before reaching the detection means of the banknote verification system. Therefore, when the skew of the bill is detected, one of the two belt transfer means forms a loop path longer than the other to change the direction of the bill, and every time the loop path rotates once, Correct a certain amount of skew.

[Problems to be solved by the invention]

The above-described skew correction device has the disadvantage that means must be used to ensure that the corner of the tip of the banknote enters the loop at a position where it engages the longer belt means. In addition, this apparatus is inconvenient because it can remove only a fixed amount of skew for each rotation of a bill.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a sheet processing apparatus which eliminates the above-mentioned drawbacks and problems of the sheet processing apparatus.

[Means for solving the problem]

In view of the above-described problems of the related art, a sheet processing apparatus according to the present invention includes a first belt unit and a second belt unit that are arranged in parallel along a traveling direction of a sheet, and moves the sheet from a first position to a first belt unit. 2. The first belt means and the second belt means, wherein each of the first belt means and the second belt means travels in a state of vertically sandwiching a sheet to be conveyed, respectively. The first belt means and the second belt means respectively push up the endless belt on the seat running surface between the first position and the second position as necessary. Alternatively, a driving means for pushing down is provided. Then, by operating one of the driving means, the traveling distance of the sheet on one side is increased, and the deflection angle of the sheet fed to the first position with respect to the traveling direction is corrected. It is configured to send to the second position. As a result, the deflection of the seat can be corrected without using a special loop path for correcting the skew of the seat.

〔Example〕

1 and 2 show a bill delay mechanism 10 of the present invention including a support frame having parallel side walls 12,14. Five fixed parallel rotating shafts 16, 18, 20, 22, 24 extend between the side walls 12, 14. The first upper pulley group 26 is fixed to the shaft 16, the second upper pulley group 28 is fixed to the shaft 18, and the third lower pulley group 30 is fixed to the shaft 20.
, And the fourth lower pulley group 32 is fixed to the shaft 22.
The pulleys 26, 28, 30, 32 of each group are mounted on the shafts 16, 18, 20, 22 at regular intervals and aligned with each other. The right ends (in FIG. 1) of the shafts 18, 22 penetrate the side wall 14, and gears 34, 36 driven by motors (not shown) via transmissions (not shown) are fixed. I have.

Mechanism 10 includes a first group of endless belts 38 and a second group of endless belts 40. Each belt 38 passes around a corresponding pair of upper pulleys 26, 28, each belt 40 passes around a corresponding pair of lower pulleys 30, 32, and a corresponding pair of belts 38, 40 are shown in FIGS. They are engaged with each other as seen in FIG. The belts 38, 40 are made of an elastomeric material such as polyurethane or silicone rubber and are designed to be elastically stretchable for the purposes described below.

The shaft 42 extends between the side walls 12, 14 in parallel with the shafts 16, 18, 20, 22, 24, and has two slots 44 formed in the side walls 12, 14, respectively.
(FIG. 2). The shaft 42 is mounted on a pair of support arms 46 near the outer surfaces of the side walls 12,14. An end of the shaft 42 is fixed to a corresponding end of the arm 46. The other end of the arm 46 is fixed to the shaft 24 and rotates around the shaft 24 by its rotation. An arm 50 extending downward is fixed to one end of the shaft 24 extending beyond the side wall 12, and a lower end of the arm 50 is connected to a solenoid 54.
The armature 52 is rotatably mounted. Arm 50
Is biased by a spring 56 to rotate clockwise in FIG. The spring 56 is a short axis 58 of the arm 50 and the side wall 12.
To be called. All four pulleys 60 are rotatably mounted on the shaft 42. The diameters of the pulleys 60 and 30, 32 are the same, and the pulleys 60 are arranged on the shaft 42 and are respectively placed inside and contacted with the four endless belts 40. Axis 42 is second
When the pulley 60 is at the normal position shown by the solid line, each pulley 60 is disposed between the corresponding pulleys 30 and 32, and its axis is flush with the axis of the corresponding pulleys 30 and 32.

A timing disk 62 (FIG. 1) is mounted at one end of the shaft 18 extending beyond the side wall 12, and the disk 62 has a group of radial marks (not shown) equally spaced around the shaft 18. Have. The disk 62 cooperates with an optical sensor 64 mounted on the side wall 12 to generate a group of timing pulses in response to sensing a mark on the disk 62. A second optical sensor 66 (FIG. 2) is located between the side walls 12, 14 and is attached to one of the side walls 12, 14. A sensor 66 is provided along the transfer path 72, and the bills being transferred by the transfer means (not shown in FIGS.
Indicates that the nip A is approaching.

Next, the operation of the bill delay mechanism 10 will be described with reference to FIG. Banknote delay mechanism 10 is an ATM that transfers banknotes one by one
Of the cash dispenser 73 (FIG. 5). The bill is transferred from the bill picking mechanism 74 (FIGS. 3 and 5) to the conventional stacking wheel 75 through the delay mechanism 10 (FIGS. 2 and 5). The stacking wheel 75 includes a plurality of stacking plates 76 separated and arranged in parallel along the stacker wheel axis 77, each plate 76 having a group of curved teeth 78. The bill removal and stacking operation is started by the electronic control unit 79 (FIG. 3) transmitting a signal PICK to the pick mechanism 75. When the pick mechanism 74 receives the signal PICK, the bill 68 is inserted into the bill cassette.
Retrieved at 89 (FIG. 5) and passed through the sensor 60 to the entry nip A of the delay mechanism 10. Normally, the solenoid 54 is in a non-energized state, and the solenoid 54 and the arm
The assembly 46, 50, the shaft 42 and the pulley 60 are held by the spring 56 at the position indicated by the solid line in FIG. As described above, when the mechanism 10 is in its normal position (non-biased state), each pulley 60
Are in the same plane as the axes of the corresponding pulleys 30, 32.
Thus, typically, the joint portion of the belts 38, 40 extends along a straight path that is aligned with the transfer path 72. When the leading end of the bill 68 (FIG. 2) is detected by the sensor 66, a signal is sent from the sensor 66 to the electronic control unit 79, and the unit 79 receives the signal and stacks correctly. Check whether the sensor 66 has been reached. The decision is a signal PICK
Is calculated based on how many times the control unit 79 has received the timing signal from the timing disk sensor 64 during the occurrence of.

The electronic control unit 79 (FIG. 3) confirms that the bill 68 has reached the sensor 66 at the correct time, and
Is not energized, and after the bill 68 enters the entry nip A, it is engaged at the joint of the belts 38, 40 and the belts 38, 40
, Along a straight path aligned with the transfer path 72.
After leaving the delay mechanism 10 at the contact outlet B between the belts 38, 40, the leading end of the bill 68 is sent to one of the cavities 81 formed between the adjacent teeth 78 of the stacking wheel 75, and then the bill Stacking is completed. Banknote 68 is at the correct time sensor 66
The control unit 79 confirms that it has not arrived at
If 68 passes the mechanism 10 as it is, the stacking wheel 75
The control unit 79 sends a signal to the solenoid 54 to energize it because it is possible to hit the teeth 78 of the solenoid. When energized, arm 50 is rotated by armature 52 toward position 50 'against the action of spring 56 (shown in dashed lines in FIG. 2). Rotation of the arm 50 moves the arm 46, shaft 42 and pulley 60 to their respective positions 46 ', 42' and 60 '(the positions indicated by the dotted lines in FIG. 2), and the shaft 42 is moved to the side walls 12, 14 in FIG. Move along the hole 44. The movement of the pulley 60 to the position 60 'deforms the joint of the belts 38, 40 to new positions 38', 40 'as shown by the dotted lines in FIG. Because the belts 38, 40 are telescopic, the joints of the belts 38, 40 are so deformable. As shown in FIG. 2, the bill 68 is transferred along the transfer path ABC
Pass through. Point C is the point of contact between belts 38, 40 partially bent about pulley 60. The transfer path ABC is clearly longer than the fixed straight path AB and the range of movement of the shaft 42 is selected as follows. That is, transfer paths ACB and A-
The difference in length between B is delayed sufficiently that the incorrect bill 68 correctly enters the void 81 of the stacking wheel 75, and if the next following bill 68 correctly reaches the sensor 66, the straight path A
Designed to correctly enter cavity 81 through -B.

The advance and delay mechanism 82 is shown in FIG. Certain elements of the mechanism 82 correspond to elements of the delay mechanism 10 of FIGS.
Corresponding elements of the mechanisms 82, 10 are given the same numbers. Thus, the advance and delay mechanism 82 comprises a group of endless belts 38 of resilient and elastic material passing through pulleys 26 and 28 mounted on shafts 16 and 18 and pulleys 30 and 28 mounted on shafts 20 and 22.
And a second group of endless belts of resilient stretchable material passing through 32. The mechanism 82 also includes a group of pulleys 60 (the pulleys 60 are disposed in contact with the inside of the endless belt 40) rotatably mounted on the shaft 42.
Are fixed to corresponding ends of a pair of support arms 46 whose other ends are fixed to the shaft 24. Further, the mechanism 82 includes a timing disk 62 and a timing disk sensor.
64 (FIG. 1) and an optical sensor 66.

Compared to the delay mechanism 10, when the mechanism 82 (FIG. 4) is in its normal position, the joint of the belts 38,40 will be in the entry nip A and The belts 38, 40 are bent away from the plane containing the outlet contact B, and the normal position of the belts 38, 40 is in tension as shown by the solid line in FIG. When the bill 68 reaches the sensor 66 of the mechanism 82 at the correct time, the belts 38, 40 remain in the correct position and the bill 6
8 passes along the transfer path AC'-B (C 'is partially bent by the pulley 60 and is the point of contact between the belts 38, 40). Again with the mechanism 10, the arm 46 of the mechanism 82
The assembly of the shaft 42 and the pulley 60 constitutes a bidirectional motor 84 which replaces the solenoid 54 of the mechanism 10. Motor 84 is shaft 24
Worm engaged with gear segment 88 fixed to
Drive 86.

The operation of the forward and delay mechanism 82 (FIG. 4) will be described with reference to FIG. The bill 68 is extracted from a cassette (not shown in FIG. 4) and sent to the sensor 66. When the mechanism 82 is in the normal position, the belts 38 and 40 are at the positions indicated by the solid lines in FIG.
At this time, the motor 84 is not energized. When the tip of the bill 66 is detected by the sensor 66, a signal is sent from the sensor 66 to the electronic control unit 79 (FIG. 3), whereby the unit
79 determines whether the bill 68 has reached the sensor 66 at the correct time, or too early or too late. In the case of the delay mechanism 10, this determination is made within the time between the reception of the signal from the sensor 66 by the control unit 79 and the generation of the signal PICK.
This is performed depending on how many timing signals from the sensor 64 are received by the control unit 79.

When the control unit 79 confirms that the banknote 68 has arrived at the sensor 66 at the correct time, the motor 84 is not energized and the banknote 68 enters the entry nip A and the belt 3
Supported along 8,40 corresponding sections and traveling along the A-C'-B transfer path. After leaving the mechanism 82, the leading end of the bill 68 is sent to the empty space 81 of the stacking wheel 75 (FIGS. 2 and 5), after which the stacking of the bill 68 is completed. If it is determined that the arrival of the bill 68 is too late, the leading end of the bill passes through the transfer path A-C'-B and the teeth 78 of the stacking wheel 75.
The control unit 79 sends a signal to the motor 84 to urge it, causing the gear segment 88 about the shaft 24 to rotate clockwise (in FIG. 4) via the worm 86. As the gear segment 88 rotates, the assembly of the arm 46, shaft 42 and pulley 60 rotates clockwise. The corresponding portions of the pulley 60 and the belts 38, 40 are located at positions 60 ", 38", 4 in FIG.
0 "and this clockwise rotation continues until shaft 42 is flush with shafts 20 and 22. When motor 84 is de-energized, belts 38 and 40 and pulley 60 are moved to positions 38" and 40. Hold at ″, 60 ″. Because the belts 38 and 40 are flexible, the belts 38 and 40 are in a state of tension as a whole even if the length is reduced. The bill 68 then passes through the mechanism 82 and through the straight path AB. Passage A
Since -B is shorter than the transfer path AC'-B, the bill 68 passes for a shorter period of time than when passing through the path AC'-B. The difference between the lengths of passages AB and AC'-B is the same as in the case where banknote 68 arrives correctly and passes through passages AC'-B and enters the correct space 81, so that passages AB are separated. Is chosen to give enough time to enter correctly.

If the control unit 79 determines that the entry of the banknote 68 is too early, the banknote may pass through the passages A-C'-B as it is.
Because of the possibility of hitting the tip of 78, unit 79 sends a signal to motor 84 which urges it in the opposite sense and rotates gear segment 88 counterclockwise (in FIG. 4). I do. This rotation causes the belts 38, 40 and the pulley 60 to move to position 38.
, 40, 60 (dotted lines in FIG. 4) and continue until the shaft 42 is higher than the normal position. At this time, the motor 84 is deenergized. Thus, the bill 68 travels along the path AC "-B. When the pulley is at position 60, C"
This is a contact point between the belts 38 and 40 that partially bend around the pulley 60. Passage A-C "-B is a regular passage A-
Since the bill 68 is longer than C'-B, the bill 68 will be
It takes longer than when you pass B. The range of movement of the shaft 42 is such that it takes sufficient time for the bill 68 to pass into the void 81, which would enter if it arrived at the correct time along the passage A-C'-B. , Passage AC ″
-B and AC'-B are chosen to produce a difference.

The cash dispensing unit 73 is included in the mechanism 10, and will be described in detail with reference to FIG. Unit 73 includes a plurality of bill cassettes 89
, And each cassette 89 has a bill stack loaded thereon. When one or more bills 68 are paid by the cash dispensing operation, the pick mechanism 74 is operated to draw out the bills 68 from the lower side of the bill stack of the cassette 89, and the leading end of the bills 68 is moved to the first pair of drive / banknotes. It moves to a position where it is gripped by the roller 90. Then, the bill 68 is sent by the drive roller 90 and is transferred by a group of drive rollers 92 to the stacking wheel 75 through the transfer path 72 and the delay mechanism 10.
Stacking wheel 75 is continuously rotating counterclockwise (FIG. 5). The teeth 78 of the stacking plate 76 pass between fingers 94 of a stripper plate assembly 96 rotatably mounted on a shaft 98. The banknote 68 that has passed through the delay mechanism 10 enters the void 81 formed between the group of teeth 78, is held for a part of the rotation of the stacking wheel 75, and is removed from the wheel 75 with the finger 94,
The bill is loaded on the belt 100 such that the long side of the bill is on the stripper plate assembly 96. As described above, if the bill 68 did not arrive at the correct time (e.g., if the tip of the bill is bent or a slip of the bill occurs).
When the control unit 79 determines, the solenoid 54 (FIG. 1,
(FIG. 2) is activated to allow the bill 68 to pass through the delay unit 10 to provide the correct time for the bill 68 to properly enter the void 81.
Delay 68.

Belt 100 is normally a shaft 104 held in the position of FIG.
Cooperate with a pair of belts (only one is shown) 102 rotatably mounted on the belt. When the bill bundle to be paid to the user in response to the payment request is loaded on the belt 100, the belt 102 rotates clockwise and is caught between the two belts 100,102. During this rotation, the belt passes between adjacent stacking plates 76. Assuming now that the bundle of banknotes 68 'is not rejected, belts 100 and 102 drive the bundle of banknotes 68' toward a pair of drive belts 106 and 106. Belt 106,1
08 transfers the bundle of banknotes 68 'to a position where the user can take it out from the payout port 110 of the housing 112 of the cash payment unit 73. Belts 100, 102 are resiliently attached to one another and belts 106, 108
Are also resiliently attached to each other so that bill bundles of different thicknesses can be held and transferred between the belts 100,102 and between the belts 106,108. Banknote 6 for belt 100
If duplicate feeds of the 8 'bundle are detected or the bill is rejected for any reason, the stripper plate assembly 96 will
The belt 100 and 102 are rotated to the position indicated by the dotted line 96 'in FIG.
The 8 'bundle is transferred in the opposite direction to the normal
It is stored in the rejected bill container 114 via 16.

Obviously, the advance and delay mechanism 82 can be used in the cash payment unit 73 instead of the delay mechanism 10.

The delay mechanism 10 of FIGS. 1 to 3 and 5 has the advantage that it is simple and versatile. Therefore, mechanism 10
Is operable to change the length of the transfer path at any time, even when the bill 68 is being fed along the transfer path 72 or after entering the mechanism 10. The advance and delay mechanism 82 (FIG. 4) has the above-mentioned advantages and also has the advantage that the length of the transfer path through the mechanism 82 can be changed indefinitely.
Moreover, by using the mechanism 10 or 82 in the cash dispensing unit 73, the picking mechanism 74 and the stacking wheel 75 do not need to be synchronized as in the normal case, thereby simplifying the structure of the unit 73.

Next, referring to FIGS.
0 will be explained. Mechanism 200 includes four elastically stretchable endless belts 202,204,206,208. Belt 202-208
Is made of a material similar to belts 38,40 made of a material that can be referred to as an elastomeric material such as polyurethane or silicone rubber. Belt 202 wraps around pulleys 210 and 212, belt 204 wraps around pulleys 214 and 216, belt 206 wraps around pulleys 218 and 220, and belt
208 goes around the pulleys 222 and 224. As seen in FIG. 6, belts 202 and 204 co-engage with each other, and similarly belts 206 and 208 co-engage with each other. The pulleys 212 and 220 are fixed to the drive shaft 226, and the pulleys 216 and 224 are
8, and the drive shafts 226, 228 are driven by the motor drive 229 in the direction indicated by the arrow in FIG. Pulley 2
10 and 218 are rotatably mounted on the fixed shaft 230 and pulley 21
The 4,222 is rotatably mounted on the fixed shaft 232. Shafts 226,22
8,230,232 all extend between the side walls 234,236 (Fig. 7)
Shafts 230,232 are fixed to walls 234,236 and drive shafts 226,228
Is rotatably mounted on walls 234 and 236.

Further, two pulleys 238, 240 (FIG. 7) are disposed in co-contact with the inside of the endless belts 202,206. The pulley 238 has a stud 24 fixed to one end of an arm 244.
2 is rotatably mounted, the other end of which passes through a side wall 234 and is fixed to one end of a shaft 246 which is rotatably mounted therein. At the same time, the pulley 240 is rotatably mounted on a stud 248 secured to one end of the arm 250 and the other end passes through a side wall 236 and is secured to one end of a shaft 252 rotatably mounted thereon. Axis 246,252 are driven by bidirectional stepper motors 254,256 respectively
Arms 244,250 selectively rotate about axes 246,252. Usually, the pulleys 238, 240 and the arms 244, 250 are in the positions indicated by the solid lines in FIG. 6, the axis of the pulley 238 is coplanar with the axis of the pulleys 210, 212, and the axis of the pulley 240 is coplanar with the axis of the pulleys 218, 220. For the reasons described below, the mechanism 200
In operation, the motor 256 is allowed to operate for a selected period of time, and the pulley 240, arm 250 assembly is moved clockwise (in FIG. 6) from its normal position, as indicated by the dotted line in FIG. Rotate to positions 240 ', 250'. This pulley 2
Movement of 40 causes the joint portion of belts 206, 208 to deform to new positions 206 ', 208' shown in FIG. Since the belts 206 and 208 are elastic, they can be deformed in this manner.
The amount of rotation of the pulley 240 and the arm 250 depends on the required belt 206,
Can be varied according to the amount of 208 deformations. Similarly,
In operation of mechanism 200, motor 254 is allowed to operate for a selected period of time, rotating pulley 238 and arm 244 clockwise (in FIG. 6) from their normal position, causing belts 206,
Belts 202,2 in a manner similar to the way joint 208 deforms
Achieve 04 joint part transformation. Each of the pulleys 238, 240 can be returned to the normal position by rotating the motors 254, 256 in the reverse direction, and the elasticity of the belts 202, 204, 206, 208 acts to return to the normal position shown by the solid line in FIG.

The timing disk 258 (FIG. 7) is fixed to the end of the shaft 226 projecting from the side wall 236, and the disk 258 is
It has a group of radial marks equally spaced around 226. The disk 258 cooperates with an optical sensor 260 mounted on the side wall 236, and the sensor 260 generates a group of timing pulses in response to sensing a mark on the disk 258.
The first and second document sensors 262,264 (FIG. 6) are mounted between the side walls 234,236 by means not shown in the figure, the axis 266 of the sensors 262,264 being in a plate parallel to the axes 226-232. Sensors 262 and 264 are the leading edge of document 270 (Figure 7)
Documents, such as banknotes, arranged to sense the passage of 268
When 70 passes through the axes 266 of the sensors 262,264, the document
It is sent to the skew correction mechanism 200 in the direction of 272.

FIG. 8 illustrates the operation of the skew correction mechanism 200 used with the bill validator 274. As shown in FIG.
After passing through the mechanism 200, the 70 is sent to the collator 274 (by means not shown). In order for the bill validator 274 to operate correctly, the billing machine 2
Must be in the right direction for 74. The correct direction is achieved when the bill 270 leaves the skew correction mechanism 200 if its tip is parallel to the axis of the shafts 226-232.

As described above, the belts 202 to 208 and the pulleys 238 and 240 are usually at the positions indicated by the solid lines in FIG. Skew correction mechanism 200
The tip 268 (FIG. 7) of the bill 270 arriving at the belt 202, 20
4 and 206,208 enter the nip, banknote 270 belt 202,204
And through the mechanism 200 to be captured during the joint portion of 206,208. When the belts 202 to 208 are in the correct positions, the bill 270 is transferred straight through the mechanism 200 without changing the direction of the tip 268 with respect to the axes 226 to 232. Outputs of the sensors 262 and 264 that detect the leading end 268 of the bill are transmitted to the electronic control unit 276 to control the operation of the motors 254 and 256.
Timing pulses generated by the timing disk sensor 260 are also supplied to the electronic control unit 276.
When the bill 270 arrives at the skew correction mechanism 200, a sensor
If 262,264 senses the tip 268 of the bill 270 at the same time (the bill is oriented in the right direction to the reconciliation machine 274), then the control unit 276 does not energize the motors 254,256, so the bill 270 has It is fed through mechanism 200 parallel to axes 226-232. If the bill is not in the correct direction as shown in FIG.
4 senses before sensor 262 senses tip 268. In that case, the control unit 276 sends a signal to the motor 256 so that the motor 256 sends a signal to rotate the arm 250 and pulley 240 assembly clockwise in FIG. This deforms the joint portion of the belts 206, 208 to a position such as positions 206 ', 208' in FIG. The rotation range of the arm 250 and the pulley 240, that is, the deformation amount of the common portion of the belts 206 and 208,
During the time period between the sensing of tip 268 by sensor 264 and the sensing of tip by sensor 262, a timing disk sensor
Control unit 276 based on the number of pulses supplied from 260
Is determined by If this period is extended, the belt 20
Increase the deformation of 6,208 joints. Belts 206, 208
Is deformed, the bill supplied to the bill correcting mechanism 200 is captured by the belts 206 and 208 (that is, the side ends 2).
The portion of the note 270 captured by the belts 202 and 204 (i.e., the portion of the note 270 near the side edge 280) is transferred along a longer transfer path. Accordingly, the bill 270 is fed through the mechanism 200 and gradually rotates around its center in the counterclockwise direction in FIG. When the bill 270 approaches the mechanism 200, the control unit 276 controls the axes 226-232.
Regardless of the amount skewed to the belt 206,
The amount of deformation of the joint portion 208 is controlled so that the leading end 268 of the bill 270 is parallel to the axes when leaving the mechanism 200. After the bill 270 leaves the mechanism 200, the control unit 276 operates the motor 256 to return the pulley 240 and the belts 206, 208 to their proper positions.

When the bill 270 approaches the skew correction mechanism 200 in a skew state opposite to the skew state shown in FIG. 7 (that is, before the sensor 264 detects the bill 270 near the side end 280, the bill 270 near the side end 278). Then, the control unit 276 sends a signal to the motor 254 to operate the motor 254 so as to rotate the assembly of the arm 244 and the pulley 238 clockwise in FIG. The deformation of the joints of the belts 202 and 204 is achieved as well as the deformation of the joints of the belts 206 and 208 of FIG. In this case, the bill 270 is
Pass through the banknote 270, the portion near the side edge 280 of the banknote 270
It travels along a longer supply path through which the portion near the zero side edge 278 passes. As in the case of the deformation of the belts 206 and 208, the electronic control unit 276 controls the rotation of the shafts 226 to 226 when the bill 270 approaches the mechanism 200.
Belts 202,2 regardless of the amount skewed against 232
Control the amount of deformation of the joint part of 04. And when the bill 270 leaves the mechanism 200, its tip 268 is parallel to the axis. After the bill 270 leaves the mechanism 200, the control unit 276
The motor 254 is operated to return the belt 38 and the belts 202 and 204 to their normal positions.

Through the skew correction rotation of the bill 270, the bill 270 is
When passed through zero and transferred by subsequent operations of the motors 254 and 256, a certain amount of slippage occurs between the bill 270 and the contact portions of the belts 202-208. The surfaces of the belts 202 to 208 are formed so that the bills 270 can be fed sufficiently smoothly and uniformly so as not to wrinkle.

The skew correction mechanism 200 ensures that the bill to be verified is genuine and arrives at the verification machine 274 in the correct direction so that the verification machine 274 can determine whether it is in a satisfactory state. Banknote 2
70 is genuine and verifies that you are in a satisfactory state
Once 274 is determined, banknote 270 can be sent from reconciliation machine 274 to a storage location. If the collator 274 fails to make the above determination (i.e., if it is torn or has something else attached), the collator 274 sends a signal to the control unit 276 and a turning means 282 (FIG. 8). ) To turn the bill 270 into a rejection bottle (not shown) or return it to the issuer.

The skew correction mechanism 200 can easily and effectively correct a wide range of skew, and the skew can be performed in two opposite directions with respect to a given axis.
