As shown in FIG. 6, the bill guide 24 moves along the slide groove 35 by fitting the slide pin 50 into the slide groove 35 provided in the frame (not shown) of the bill deposit / withdrawal portion 11. Supported as possible.

The bill press 26 is arranged so as to face the bill guide 24, forms one surface on the rear side of the storage space of the bill M in the bill deposit / withdrawal portion 11, and is movable in the front-rear direction by a drive mechanism (not shown). When paying out the bill M, it moves to the pickup roller 21 side together with the bill guide 24 and presses the bill M against the pickup roller 21.

Further, as shown in FIG. 5, the bill press 26 is also placed in the accommodation space from the lower side so that the root portion can protrude from the bottom plate 10a (FIG. 3) at a position facing the root portion of the bill elevating plate 40. Three notch holes 26c having a height that allows them to rise toward the surface are provided.

Further, the bill press 26 is provided with two slide pins 30 along the front-rear direction at both ends in the longitudinal direction (left-right direction). As shown in FIG. 6, the bill press 26 moves along the slide groove 35 by fitting the slide pin 30 into the slide groove 35 provided in the frame (not shown) of the bill deposit / withdrawal unit 11. Supported as possible.

The slide groove 35 is formed by a front portion 35a extending in the front-rear direction, a rear portion 35b one step higher than the front portion 35a, and an inclined bent portion 35c connecting between the front portion 35a and the rear portion 35b.

In the bent portion 35c of the slide groove 35, when the bill press 26 moves rearward and the slide pin 30 enters the bent portion 35c, the support surface 26a (opposing surface) of the bill press 26 becomes the contact surface 24a of the bill guide 24. From the state parallel to (opposing surface) (FIG. 7), the inclined surface 26b on the upper side of the surface facing the bill guide 24 in the bill press 26, which is tilted toward the integrated tongue piece roller 28, is the contact of the bill guide 24. The tilt angle is set so that the bill press 26 is tilted so as to be in a state substantially parallel to the contact surface 24a (FIG. 8).

The bill press 26 is provided with a position detection plate 31 below one end in the longitudinal direction thereof. For example, the position detection plate 31 blocks the optical axis of the position sensor 33 including an optical light receiving sensor and a light emitting sensor. Then, the position is detected. The bill guide 24 is also provided with a position detection plate 60 below one end in the longitudinal direction thereof, and the position of the position detection plate 31 is detected by a position sensor 70 similar to the position sensor 33. Each of the bill processing devices position sensors 33 and 70 has a U-shape with its opening pointed upward, and the position detection plates 31 and 60 block the optical axis between the light receiving sensor and the light emitting sensor to guide the bill. The positions of 24 and the bill press 26 are detected.

The integrated tongue piece roller 28 is a roller having a plurality of tongue pieces, and when the banknote M stored in the banknote storage unit 15 or the temporary storage unit 17 is transported to the banknote deposit / withdrawal unit 11 via the transport path 13. , The rear end of the bill M discharged into the bill deposit / withdrawal unit 11 is tapped to collect the bills on the bill guide 24.

[Operation of banknote deposit / withdrawal section]
Each unit of the banknote deposit / withdrawal unit 11 operates according to the control of the main control unit MCTL when the banknote M is inserted by the customer. Specifically, in the bill deposit / withdrawal unit 11, the bill guide 24 and the bill press 26 are moved so as to be narrower than the opening of the bill deposit / withdrawal port 5a and have a storage space that can be accessed by the customer, and then the shutter 20. Is opened.

Then, in the bill deposit / withdrawal unit 11, when the bill M is inserted into the accommodation space by the customer through the bill deposit / withdrawal port 5a, the shutter 20 is closed. After the shutter 20 is closed, the bill press 26 is moved to the bill guide 24 side, and the bill M inserted by the bill guide 24 and the bill press 26 is held in a standing position.

In the bill deposit / withdrawal section 11, the bill guide 24 and the bill press 26 are moved to the pickup roller 21 side while the bill M is sandwiched between the bill guide 24 and the bill press 26, and the pickup roller 21 is notched in the bill guide 24. It protrudes from the hole 24b into the accommodation space and comes into contact with the bill M (FIG. 7).

After that, in the bill deposit / withdrawal unit 11, the pickup roller 21 and the feed roller 22 rotate in the direction of feeding the bill M (counterclockwise in FIG. 7), and the bills M in contact with the pickup roller 21 are separated one by one. Then, it is delivered to the transport path 13.

[Composition and operation of foreign matter discharge]
Here, the operation of discharging foreign matter from the bill deposit / withdrawal unit 11 will be described. The main control unit MCTL starts moving the pill press 26 toward the banknote guide 24 after the banknote M is inserted into the storage space by the customer, the shutter 20 is closed, and the banknote M is fed to the transport path 13. The thickness (number of sheets) of the banknotes M inserted into the accommodation space is calculated based on the moving distance of the bill press 26 when the banknotes M are narrowly held between the banknote guide 24 and the banknote guide 24. Therefore, the banknote deposit / withdrawal unit 11 has a storage space for inserting banknotes as shown in FIGS. 3 and 9.

The storage space is surrounded by a bill guide 24, a bill press 26, and a bottom plate 10a. The foreign matter accommodating portion 12 includes an opening 100 arranged below the accommodating space. The bill insertion slot width L1 is the distance between the support surface 26a of the bill press and the contact surface 24a of the bill guide 24 at the bill insertion position (FIG. 3), and is (assumed thickness per handling bill). The width calculated by x (the maximum number of banknotes to be inserted) is set to a size that is equal to or less than the short length of the banknotes handled.

The width L2 of the opening 100 is wider than the bill insertion slot width L1 between the support surface 26a of the bill press 26 and the contact surface 24a of the bill guide 24 at the insertion position of the bill M. Specifically, when the bill press 26 and the bill guide 24 swing in the front-rear direction with respect to the bill insertion slot width L1, each of the support surface 26a of the bill press 26 and the bill guide 24 contact surface 24a The width of the opening 100 is set to two sides in the L2 direction and an amount to be overlapped by a predetermined amount.

Further, as shown in FIGS. 3 and 9, the upper four sides of the opening 100 are inclined so as to be narrowed at an arbitrary angle (for example, 45 degrees or more) from the upper side to the lower side. Further, as shown in FIG. 9, a plurality of holes are formed in the bottom plate 10a. A plurality of holes are provided so as to be larger than a coin and smaller than a stub bill in which the bill M is half-folded in the lateral direction.

About the space height L3 (the space having the height indicated by the double-headed arrow in FIG. 3) which is the height between the bottom surface of the shutter 20 and the bottom plate 10a supporting the lower end of the bill inserted in the storage space. explain. The space height L3 is set in addition to a predetermined swing amount of the bill elevating plate 40 and a short length of the bill to be handled so that the bill M does not come into contact with the shutter 20 when the bill M is raised by the bill elevating plate 40. It is determined by the total value with an arbitrary gap amount.

The main control unit MCTL moves the bill press 26 to the bill guide 24 side as shown in FIG. 10A after the bill is inserted from the customer and closes the shutter 20, and is formed by the bill guide 24, the bill press 26, and the bottom plate 10a. The banknote M in the storage space is held in a standing position, and the thickness of the banknote M is measured.

Here, a method of measuring the thickness of the banknote M using the thickness detecting means in this embodiment will be described with reference to FIGS. 10A and 10B. The bill press 26 uses a bill press stepping motor (not shown) as a drive source, and moves by transmitting a driving force from the bill press stepping motor using a predetermined link mechanism or the like. When the building press 26 moves, the pulse count value of the stepping motor for building press (not shown) and the position data of the building press 26 (building press movement amount) are associated with each thickness of the bill, and the main control unit is used. It is stored in the MCTL, and the bill thickness and the number of inserted bills are calculated.

First, as shown in FIG. 10A, the main control unit MCTL moves the bill press 26 (shown by a broken line) and the bill guide 24 to a predetermined bill insertion position by position detection by the position sensors 33 and 60. Here, the main control unit MCTL stores the pulse count value of the stepping motor for bill press 26 (not shown) as 0 (FIG. 10B (A)).

The main control unit MCTL turns on the stepping motor for the bill press, moves the bill press 26 toward the bill guide 24 side, and at the position from the predetermined bill insertion position (pulse count value zero) of the bill press 26. The change is detected by the position sensor 33. That is, the main control unit MCTL stores the pulse count value A at the time when the position detection plate 31 does not block the optical axis of the position sensor 33 with the movement of the bill press 26 and becomes a bright state (OFF) as an initial value. (FIG. 10B (B)).

Then, the main control unit MCTL sandwiches the bill M inserted into the accommodation space in the process of moving the bill press 26 toward the bill guide 24 with the bill guide 24, and presses the bill M and the bill guide 24. While moving it to the bill guide 24 side.

In the main control unit MCTL, the bill guide 24 moves toward the pickup roller 21 due to the pressure caused by the movement of the bill press 26, and the position detection plate 70 of the bill guide 24 blocks the optical axis of the position sensor 70 with this movement. When the light state (OFF) is detected (solid line in FIG. 10B), the stepping motor for the bill press 26 is turned off (solid line in FIG. 10B (A)), and the banknote guide 24 is moved. The guide 26 motor (not shown) is turned on to stop the movement of the bill guide 24 (FIG. 10B (D)). The main control unit MCTL stores the pulse count value of the stepping motor for the bill press 26 at rest as B1 (with bills).

On the other hand, the main control unit MCTL is in a state where there are no banknotes in the accommodation space (at the time of 0 sheets), for example, the initial operation immediately after the device power is turned on, and each mechanism movable part (not shown for the next transaction) is designated. During the mode reset operation to return to the position, the bill press 26 is moved toward the bill guide 24 side in the same manner as described above, and the support surface 26a of the bill press 26 is brought into contact with the contact surface 24a of the bill guide 24. In the main control unit MCTL, the bill guide 24 moves toward the pickup roller 21 due to the pressure caused by the contact of the bill press 26, and the position detection plate 70 of the bill guide 24 blocks the optical axis of the position sensor 70 with this movement. When it disappears and a bright state (OFF) is detected (Dashed line in FIG. 10B (C)), the stepping motor for the bill press 26 is turned off (Dashed line in FIG. 10B (A)), and the bill guide 24 is moved. The guide 26 motor (not shown) is turned on to stop the movement of the bill guide 24 (FIG. 10B (E)). The main control unit MCTL stores in advance the pulse count value of the stepping motor for the bill press 26 at rest as B0 (without banknotes).

Here, let D be the difference (B0-A) between the pulse count value A of the initial value of the stepping motor for the bill press 24 and the pulse count value B0 at 0 sheets, and the pulse count value A and the pulse count value B1 when there is a bill. With the difference (B1-A) from the above as C, the main control unit MCTL calculates the "banknote thickness" (1) and the "number of inserted banknotes" (2) of the inserted banknote M by the following formula.
Banknote thickness = (DC) x amount of movement per pulse (specified value) ... (1)
Number of inserted banknotes = banknote thickness / thickness per assumed banknote ... (2)

Based on the number of bills (thickness) calculated in this way, the main control unit MCTL executes the foreign matter discharging operation.

For example, when the number of banknotes M inserted into the banknote deposit / withdrawal unit 11 is 1 to 50, the main control unit MCTL calculates the thickness of the banknote M by the method described above, and the banknotes are based on the thickness of the banknote M. It is determined that the number of M's is "small amount".

After that, the main control unit MCTL moves the bill press 26 back to the original bill insertion position (FIG. 3) from the state where the bill M is sandwiched between the bill press 26 and the bill guide 24 as shown in FIG. 10A (banknote guide). Move in the direction away from 24). At the same time, as shown in FIG. 11A, the banknote guide 24 is moved in a direction (rear) closer to the bill press 26 side by a predetermined amount, and then away from the original banknote insertion position side by a predetermined amount (front). Perform the movement operation multiple times. That is, the bill M is shaken by temporarily releasing the state in which the bill M is sandwiched between the bill press 26 and the bill guide 24 and moving the bill guide 24 back and forth. This causes foreign matter such as coins to fall.

As shown in FIG. 11B, when the number of banknotes M inserted into the banknote deposit / withdrawal unit 11 is 51 to 100, the main control unit MCTL has a "medium amount" of banknotes M based on the thickness of the banknotes M. Judge that.

After that, the main control unit MCTL moves the bill press 26 in the direction of returning to the original bill insertion position as described above, and moves the bill guide 24 in the front-rear direction by a predetermined amount a plurality of times. Further, the main control unit MCTL performs a plurality of operations of moving the banknote M up and down by the banknote elevating plate 40 in addition to the operation of the bill press 26 and the banknote guide 24. That is, once the state in which the bill M is sandwiched between the bill press 26 and the bill guide 24 is released, and the bill guide 24 is moved back and forth, the bill M is swung, and at the same time, the bill M is moved up and down by the bill lifting plate 40. Vibrate. This causes foreign matter such as coins to fall.

As shown in FIG. 11C, when the number of banknotes M inserted into the banknote deposit / withdrawal unit 11 is from 101 to the maximum number of banknotes to be inserted, the main control unit MCTL has a "large number of banknotes M" based on the thickness of the banknotes M. It is judged that it is.

After that, the main control unit MCTL moves the bill press 26 to the opposite side of the bill guide 24 by a predetermined distance including the distance moved in the direction approaching the bill guide 24 from the insertion position and an arbitrary distance. The operation of moving the bill guide 24 side by the same distance as the predetermined distance is performed a plurality of times. At the same time, the bill guide 24 is also moved a predetermined amount in the front-rear direction a plurality of times.

Further, the main control unit MCTL performs a plurality of operations of moving the banknote M up and down by the banknote elevating plate 40 in addition to the operation of moving the bill press 26 and the banknote guide 24 in the front-rear direction. That is, the bill M is swung by moving the bill press 26 and the bill guide 24 in the front-rear direction, and the bill M is vibrated up and down by the bill elevating plate 40. This causes foreign matter such as coins to fall.

The amount of movement of the bill press 26, the bill guide 24, and the bill lifting plate 40 is an amount that the clamping force between the bills is released when the bill press 26, the bill guide 24, and the bill lifting plate 40 are moved. It is desirable that the amount of the banknotes is, for example, 5 mm or more so that there is a gap between the banknotes. By doing so, the pinching force of the foreign matter caught between the bills can be released.

As described above, according to the first embodiment, the bill M is swung in the front-rear direction by the bill press 26 and the bill guide 24 before the bill M inserted into the bill deposit / withdrawal unit 11 is separated and unwound. In addition, by vibrating the bill elevating plate 40 in the vertical direction, foreign matter mixed by mistake can be discharged to the foreign matter accommodating portion 12 more efficiently.

Further, the banknote M inserted into the banknote deposit / withdrawal unit 11 is separated, and the thickness of the banknote M is calculated from the moving distance of the bill press 26 to determine the number of banknotes M before the banknote M is unwound. Change the mechanism to make it. As a result, even if the number of bills M to be inserted into the bill deposit / withdrawal port 11 is different for each transaction, the foreign matter discharge operation can be performed according to the number of bills M to be inserted, and the foreign matter can be discharged more efficiently. It can be discharged to the accommodating portion 12.

In the first embodiment, the measurement of the number of inserted bills has been described by moving the bill press 26, but the bill guide 24 may be moved instead of the bill press 26. That is, the main control unit MCTL relatively moves the bill guide 24 and the pill press 26, holds the bill M between them, and calculates the number of bills inserted from the moving distance of either the bill guide 24 or the pill press 26. be able to.

[Second Example]
In this embodiment, instead of calculating the "banknote thickness" or the like using the movement amount of the bill press 26, the "banknote thickness" or the like is calculated from the image of the banknote obtained by photographing the storage space of the banknote. Since it is the same as that of the first embodiment, the same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In contrast to the first embodiment, in this embodiment, as shown in FIG. 12, an image capturing device 200 is provided in a frame (not shown) of the bill deposit / withdrawal unit 11 as a thickness detecting means. The image capturing device 200 is arranged on the side surface of the storage space composed of the bill press 26, the bill guide 24, and the bottom plate 10a, and captures and acquires an image of the side surface of the bill M inserted in the storage space. It has a configuration in which the image is transmitted to the main control unit MCTL.

[Explanation of operation]
When the main control unit MCTL detects that the bill M has been inserted into the accommodation space by a sensor (not shown), the main control unit MCTL moves the shutter 20 in the closing direction to close the bill deposit / withdrawal port 5a. After that, the main control unit MCTL photographs the banknotes M inserted into the accommodation space by the image capturing device 200 before the banknotes are separated and fed out, and the number of banknotes M inserted and the banknotes M are inserted based on the acquired image. Determine the state.

As a method of determining the number of banknotes M from the image, for example, as the number of banknotes M inserted increases, the thickness increases in the front-rear direction as shown in FIG. 11, so that the width of the banknote M in the front-back direction is an image. It may be recognized by processing and the number of banknotes M may be determined based on the width in the front-back direction.

As shown in FIGS. 13 and 14, the main control unit MCTL changes the foreign matter discharging operation according to the number of bills and the insertion state. Here, it is assumed that the number of bills inserted into the bill deposit / withdrawal unit 11 is a "medium amount" of 51 to 100 bills.

From the image of the banknote M taken by the image capturing device 200, the main control unit MCTL is a "medium-weight" banknote M having 51 to 100 banknotes as shown in FIG. 13A, and the banknote guide 24 is on the upper side thereof. It is judged that the banknote is thrown in the state of being tilted toward the side. In this case, the main control unit MCTL moves the bill press 26 toward the bill guide 24 by a predetermined amount and then moves it away from the bill guide 24 by a predetermined amount. That is, the bill M is swung by moving the bill press 26 in the front-rear direction (FIG. 13B). At the same time, the main control unit MCTL vibrates the bill M up and down by moving the bill elevating plate 40 up and down a plurality of times as in the first embodiment. This causes foreign matter such as coins to fall.

On the other hand, when the main control unit MCTL determines that the banknotes are inserted in a state where the upper side of the "medium amount" banknote M is tilted toward the bill press 26 side as shown in FIG. 14A, the banknote guide After moving the 24 to the bill press 26 side by a predetermined amount, it is moved in a direction away from the bill press 26 by a predetermined amount. That is, the banknote M is swung by moving the banknote guide 24 in the front-rear direction (FIG. 14B). At the same time, the main control unit MCTL vibrates the bill M up and down by moving the bill elevating plate 40 up and down a plurality of times as in the first embodiment. This causes foreign matter such as coins to fall.

When the main control unit MCTL determines from the image of the banknote M taken by the image capturing device 200 that the number of banknotes inserted into the banknote deposit / withdrawal unit 11 is a "small amount" of 1 to 50, the banknotes As in the case where M is "medium amount", the bill press 26 or the bill guide 24 is operated to perform the foreign matter ejection operation. When the bill M is a "small amount", the operation of the bill lifting plate 40 may be omitted.

Further, when the main control unit MCTL determines from the image of the banknote M taken by the image capturing device 200 that the number of banknotes inserted into the banknote deposit / withdrawal unit 11 is "a large amount" of 101 to the maximum number of banknotes to be inserted. Similar to the first embodiment, the bill press 26, the bill guide 24, and the bill lifting plate 40 are operated to discharge foreign matter.

The main control unit MCTL operates as described in the first embodiment when the bill M is inserted in a state substantially parallel to each of the support surface 26a of the bill press 26 and the contact surface 24a of the bill guide 24. Similarly, the foreign matter ejection operation is performed according to the number of bills M.

As described above, according to the second embodiment, the number of inserted banknotes M and the inserted state are determined from the image taken in the accommodation space before the banknotes are separated and carried over, and the foreign matter ejection operation is performed based on this determination result. By changing the above, it is possible to perform a foreign matter discharging operation according to the number of bills and the insertion state, which are different for each transaction, and it is possible to discharge the foreign matter such as coins mixed by mistake to the foreign matter accommodating portion 12.

The above embodiment has been described with an example in which the swinging motion is divided into three divisions of 1 to 50 sheets, 51 to 100 sheets, and 101 to the maximum number of sheets to be loaded, but the number of sheets for changing the foreign matter discharging operation is appropriately changed. You may.

Further, in the first embodiment, when the number of banknotes M to be inserted is "small amount" of 1 to 50, the example of not moving the banknote elevating plate 40 has been described, but the banknote M is "medium amount". It may be moved at the same time as the bill guide 24 as in the case of "large amount".
