[1-2. Reject cassette configuration]
Next, the configuration of the reject cassette 17 will be described. As shown in FIG. 2, the reject cassette 17 has a configuration in which a housing 31 occupying a lower portion and a lid 32 occupying an upper portion are connected via a rotating portion 33.

The storage body 31 and the lid body 32 are both formed in a rectangular parallelepiped shape, and the lengths in the front-rear direction and the left-right direction are made to coincide with each other. The rotation unit 33 is a rotation mechanism having a central axis directed in the left-right direction, and is attached to the vicinity of the upper end of the front surface of the storage body 31 and the vicinity of the lower end of the front surface of the lid body 32. The rotation unit 33 can rotate the lid 32 relative to the storage body 31 in the direction indicated by the arrow R1 in the clockwise direction in FIG.

That is, as shown in FIG. 2, the reject cassette 17 rotates the storage body 31 in the direction of the arrow R1 from the state in which the lid body 32 overlaps directly above the storage body 31 (hereinafter referred to as the closed state). As shown in FIG. 3, the state can be changed to a state in which the lid body 32 is positioned on the front upper side of the storage body 31 (hereinafter referred to as an open state). Further, the reject cassette 17 returns to the closed state (FIG. 2) in which the lid body 32 is stacked directly on the storage body 31 by the lid body 32 being rotated in the direction of the arrow R <b> 2 from the open state (FIG. 3). be able to. At this time, the lid body 32 blocks the inside of the storage body 31 from the outside.

Also, a lock 34 that is locked or unlocked by the key K1 is provided on the rear surface of the storage body 31. When the lock 34 is locked when the lid 32 is in the closed state, the lock 34 is maintained in the closed state and prohibits transition to the open state. Further, when the lock 34 is unlocked by the key K1, the lid 32 allows the cover 32 to transition to the open state.

The storage body 31 is formed in a hollow rectangular parallelepiped shape, and a communication hole 31H (FIG. 4) is formed on the upper side thereof for communicating the internal space with the outside. The internal space of the storage body 31 is divided into a first storage portion 36 on the front side and a second storage portion 37 on the rear side by a plate-like partition plate 35 located substantially in the center in the front-rear direction. As for this 1st storage part 36 and the 2nd storage part 37, as for all, the 1st storage space 36S and the 2nd storage space 37S which store a bill are formed in the inside, and the upper side is opened. For this reason, when the reject cassette 17 is in the open state (FIG. 3), the first storage portion 36S and the second storage space 37S can be opened simultaneously with the first storage portion 36S and the second storage space 37S being arranged side by side. it can.

As described above, the storage body 31 is provided with the passage hole 17U and the discharge unit 38 for allowing the bills conveyed from the switching unit 15 (FIG. 1) to pass therethrough. The discharge unit 38 is configured by a plurality of rollers or the like, and discharges the bills conveyed through the passage hole 17U into the first storage space 36S on the rear side. Incidentally, the discharge part 38 is configured such that a driving force is transmitted from a motor (not shown) provided on the housing case 10 side via a predetermined gear (not shown). For this reason, the reject cassette 17 is not provided with electric parts such as a motor.

The lid body 32 is generally formed in a rectangular parallelepiped shape whose periphery is closed, and an intake hole 17H is formed in front of the center on the upper surface. Further, inside the lid body 32, as an inner side surface connecting the intake hole 17H and the second storage space 37S positioned below the intake hole 17H when in the closed state (FIG. 2), the front side The first guide surface 41 and the rear second guide surface 42 are provided.

The first guide surface 41 is a flat surface inclined to lower the rear side with respect to the upper surface of the lid, that is, a flat surface inclined with respect to both the horizontal direction and the vertical direction, and is closed (FIG. 2). , The lower end is substantially the same as the rear surface of the partition plate 35. Incidentally, the inclination angle of the first guide surface 41 is substantially equal to the inclination angle of the front side surface 24F in the rear guide 24 of the bundle transport unit 3 (FIG. 1).

The second guide surface 42 is a flat surface inclined at the same inclination angle as the first guide surface 41. A communication space 43 is provided between the first guide surface 41 and the second guide surface 42 on the rear side to allow communication between the upper side of the intake hole 17H, that is, the outside of the reject cassette 17 and the inside of the second storage space 37S. Is formed. In the reject cassette 17, the first guide surface 41 and the second guide surface 42 can also be regarded as the lower side surface and the upper side surface of the communication space 43, respectively.

From another viewpoint, the reject cassette 17 can be easily accessed by arranging the first storage space 36S and the second storage space 37S horizontally. On the other hand, in the reject cassette 17, the intake hole 17H is positioned almost directly above the first storage portion 36S in relation to the lower conveyance path space 28 in the bundle conveyance unit 3. Therefore, the reject cassette 17 causes the communication space 43, the first guide surface 41, and the like to be inclined with respect to the horizontal direction and the vertical direction, and causes the banknote bundle W to fall obliquely downward.

Further, a shutter 45 is provided near the upper surface of the lid 32. The shutter 45 is formed in a thin plate shape in the up-down direction, and the length in the front-rear direction and the left-right direction is longer than the intake hole 17H. The shutter 45 is configured to be movable in the front-rear direction. That is, when the shutter 45 is moved forward, as shown by the solid line in FIG. 2, the shutter 45 closes the intake hole 17H near the upper end of the communication space 43, and when it is moved backward, As shown in FIG. 1 and as indicated by a broken line in FIG. 2, the intake hole 17H is opened.

The shutter 45 opens and closes in conjunction with the attachment / detachment of the reject cassette 17 with respect to the storage housing 10 of the storage unit 2. That is, the shutter 45 is moved rearward to open the intake hole 17H when the reject cassette 17 is attached to the housing case 10 (FIG. 1). Further, the shutter 45 is moved forward when the reject cassette 17 is removed from the storage housing 10, and closes the intake hole 17H.

Also, the lid 32 incorporates a lock mechanism (not shown) that locks the shutter 45 in conjunction with the attachment / detachment of the reject cassette 17 with respect to the storage housing 10 of the storage unit 2 or releases the lock. This locking mechanism locks the position of the shutter 45 when the reject cassette 17 is removed from the storage housing 10 and the shutter 45 is moved forward to close the intake hole 17H. In addition, this lock mechanism releases the lock and allows the shutter 45 to move when the reject cassette 17 is mounted on the storage housing 10.

Therefore, if the reject cassette 17 is removed from the storage housing 10 and the intake hole 17H is closed by the shutter 45, the shutter 45 is locked by the lock mechanism. It is extremely difficult to move 45 backward, that is, to open the intake hole 17H.

[1-3. Withdrawal and import operations]
The banknote dispensing machine 1 (FIG. 1) starts a dispensing operation when receiving a withdrawal instruction and a withdrawal amount from a user through an operation unit (not shown). Specifically, the control unit 4 of the banknote dispensing machine 1 sequentially feeds out banknotes of the denomination and the number of banknotes corresponding to the withdrawal amount from the banknote cassette 11, and the transport unit 13 uses the direction along the short side of the banknote as the traveling direction. Is conveyed upward and is discriminated by the discrimination unit 14. At this time, based on the discrimination result obtained from the discrimination unit 14, the control unit 4 determines the transport destination to be the stacking unit 16 or the reject cassette 17 depending on whether or not banknotes can be withdrawn.

Subsequently, the control unit 4 causes the conveyance unit 13 to convey the banknotes identified by the identification unit 14 backward and upward to reach the switching unit 15. Based on the control of the control unit 4, the switching unit 15 switches the advancing direction according to the conveyance destination determined for each bill and advances the stacking unit 16 or the reject cassette 17. The reject cassette 17 (FIG. 2) takes in the banknote (that is, reject banknote) conveyed from the switching unit 15 (FIG. 1) into the inside through the passage hole 17U, and discharges it into the first storage space 36S by the discharge unit 38. Accumulate.

The stacking unit 16 discharges the conveyed banknotes into the stacking space 16S by the discharge unit and stacks it on the stage 16T. The control unit 4 sequentially counts the denominations and the number of banknotes collected in the stacking unit 16, that is, the banknotes stacked in the stacking unit 16, and the bill cassette 11 Stops paying bills from. As a result, on the stage 16T of the stacking unit 16, a banknote bundle W in which banknotes to be withdrawn are stacked in a bundle is placed.

Next, the control unit 4 opens the stacking hole 16H of the stacking unit 16 by moving the bundle conveyance guide 22 backward and closes the intake hole 17H, and then moves the stage 16T upward to move the banknote. The bundle W is lifted and positioned in the bundle conveyance path 3Y. Further, the control unit 4 advances the banknote bundle W forward along the bundle conveyance path 3Y by moving the upper conveyance belt 21 forward and moving the raschel portion 25 forward. At this time, when the banknote bundle W reaches the position where the banknote bundle W comes into contact with the upper surface of the lower conveyor belt 23, the controller 4 sandwiches the banknote bundle W from above and below by the upper conveyor belt 21 and the lower conveyor belt 23, and both belts travel. To move forward.

Eventually, when the control unit 4 detects that the banknote bundle W has reached the dispensing port 26 based on a notification from a sensor (not shown), the control unit 4 stops the travel of the upper transport belt 21 and the lower transport belt 23. Further, the control unit 4 causes the russell portion 25 to reach the vicinity of the front end of the bundle conveyance path 3Y, thereby retracting it above the bundle conveyance path 3Y by a retraction mechanism (not shown).

In this way, the control unit 4 exposes a part of the banknote bundle W from the withdrawal port 26 and withdraws the banknote W near the rear end of the banknote bundle W by the upper transport belt 21 and the lower transport belt 23. End the operation. Thereby, the banknote dispensing machine 1 can make the user take out the banknote bundle W.

Here, the control unit 4 monitors whether or not the banknote bundle W has been taken out from the withdrawal port 26 based on a notification from a sensor (not shown). Therefore, if the banknote bundle W is not removed even after a predetermined waiting time (for example, 30 seconds) has elapsed, the control unit 4 regards that the banknote bundle W has been forgotten to be removed, and takes in the banknote bundle W. Start the operation. Hereinafter, the banknote forgotten by the user is also referred to as a forgotten banknote or a retracted banknote.

Specifically, the control unit 4 takes the banknote bundle W into the bundle conveyance path 3Y by running the upper conveyance belt 21 and the lower conveyance belt 23 backward while the raschel portion 25 is retracted upward, Advancing backward along the bundle conveying path 3Y. At this time, when the control unit 4 detects that the banknote bundle W has arrived behind the raschel section 25 by a sensor (not shown), the control section 4 moves the raschel section 25 rearward and enters the bundle transport path 3Y on the front side of the banknote bundle W. After returning, the backward movement of the banknote bundle W is assisted by moving further backward.

Eventually, when the banknote bundle W reaches above the intake hole 17H, the control unit 4 drops the banknote bundle W from the bundle transport path 3Y. At this time, the banknote bundle W descends in the rear lower direction in the conveyance path rear lower space 28 while being guided in the rear lower direction by the front side surface 24F of the rear guide 24 and eventually enters the reject cassette 17 from the intake hole 17H. . In the reject cassette 17, the banknote bundle W descends rearward and downward in the communication space 43 while sliding with its lower surface abutting against the first guide surface 41, and eventually reaches the second storage space 37S for storage. Is done.

For convenience of explanation, in the following, in the rear space 28 and the communication space 43 that are in communication with each other, the rear lower direction, which is the direction in which the banknote bundle W travels, is also referred to as the downstream side. A certain front upper side is also called an upstream side.

In this way, the reject cassette 17 takes in the banknote bundle W (that is, the bundle of forgotten banknotes) that the user has forgotten to remove from the intake hole 17H, descends the communication space 43 along the

first guide surface

41, 2 The storage space 37S is reached and stored.

[1-4. Configuration of banknote bundle detection unit]
In addition to such a configuration, the banknote dispenser 1 includes a banknote bundle detection unit that detects the presence or absence of the banknote bundle W at a position that spans the boundary between the bundle transport unit 3 and the reject cassette 17, as shown in FIG. 60 is provided. The banknote bundle detection unit 60 is a so-called optical sensor, and can detect the presence or absence of an object (for example, banknote bundle W) on the optical axis using predetermined detection light.

[1-4-1. Configuration and Basic Operation of Each Unit] The banknote bundle detection unit 60 includes a light emitting unit 61 and a light receiving unit 62 provided on the bundle conveyance unit 3 side, and a prism 63 provided on the reject cassette 17 side. The light emitting unit 61 is attached to the left side of the center in the left-right direction on the rear upper side of the front side surface 24F in the rear guide 24 of the bundle transport unit 3. The light emitting unit 61 is electrically connected to the control unit 4 (FIG. 1), a power supply circuit (not shown), and the like, and detects the detection light L (hereinafter referred to as “the detection light L” toward the front lower direction that is the normal direction of the front side surface 24F). The first detection light L1 is also emitted. Incidentally, a through hole (not shown) for allowing the first detection light L1 to pass through is formed in the front side surface 24F.

The first detection light L1 travels through the conveyance path rear lower space 28 which is a space in front of the front side surface 24F in the bundle conveyance unit 3 through a through hole (not shown) formed in the front side surface 24F. After that, it eventually passes through the intake hole 17H, proceeds in the communication space 43 on the reject cassette 17 side, and then reaches the first guide surface 41. Similar to the front side surface 24F, the first guide surface 41 is formed with a through hole (not shown) for allowing the first detection light L1 to pass therethrough, and this detection light L travels forward and downward.

A prism 63 is attached to the front lower side of the first guide surface 41 and where the first detection light L1 travels, that is, the normal direction side of the front side surface 24F with respect to the light emitting unit 61. ing. The prism 63 has a sufficient length in the left-right direction, and a plurality of reflecting surfaces that reflect light are formed. For this reason, the prism 63 changes the traveling direction of the detection light L (first detection light L1) traveling in the forward and downward direction to the right, travels a predetermined distance, and further moves the traveling direction backward and upward. Change direction. Hereinafter, the detection light L traveling in the rear upper direction is referred to as a second detection light L2.

Incidentally, the prism 63 positions and angles of the respective reflecting surfaces so that the optical axis X2 of the second detection light L2 is positioned at a location that is substantially symmetrical in the communication space 43 with respect to the optical axis X1 of the first detection light L1. Etc. have been adjusted. Further, the first guide surface 41 has a through-hole (not shown) for allowing the second detection light L2 to pass through the part corresponding to the second detection light L2 as well as the part corresponding to the first detection light L1. ) Is formed.

After passing through the through hole of the first guide surface 41, the second detection light L2 travels through the communication space 43 and passes through the intake hole 17H, and passes through the lower space 28 after the conveyance path on the bundle conveyance unit 3 side. After traveling, it passes through a through hole (not shown) formed in the front side surface 24F and reaches the rear upper side of the front side surface 24F.

A light receiving portion 62 is attached to a location where the second detection light L2 reaches on the rear upper side of the front side surface 24F, that is, a location on the right side of the light emitting portion 61 and substantially symmetrical to the light emitting portion 61. Similar to the light emitting unit 61, the light receiving unit 62 is electrically connected to the control unit 4 (FIG. 1), a power supply circuit (not shown), and the like, and when receiving the second detection light L2, the amount of received light (that is, light intensity). A light receiving signal having a signal level (that is, voltage) corresponding to is generated and supplied to the control unit 4.

The control unit 4 recognizes whether or not the detection light L has reached the light receiving unit 62 based on the signal level of the light reception signal, and then determines the detection result of the banknote bundle W by the banknote bundle detection unit 60. Specifically, when the detection light L reaches the light receiving unit 62, the control unit 4 does not block both the first detection light L <b> 1 and the second detection light L <b> 2 with the banknote bundle W, and thus the banknote bundle detection unit 60. It is determined that the banknote bundle W has not been detected. In addition, when the detection light L does not reach the light receiving unit 62, the control unit 4 has at least one of the first detection light L1 and the second detection light L2 blocked by the banknote bundle W, and thus the banknote bundle detection unit 60. It is determined that the banknote bundle W is detected.

[1-4-2. Detailed layout of each part]
Next, the detailed arrangement of the light emitting unit 61, the light receiving unit 62, and the prism 63 in the banknote dispensing machine 1 will be described in detail with reference to FIG. 5A.

In the reject cassette 17 of the banknote dispenser 1, when the shutter 45 is normally closed, the front end thereof is brought into contact with or very close to the first guide surface 41 as shown by a broken line in the drawing. As a result, the reject cassette 17 hardly forms a gap between the shutter 45 and the first guide surface 41, and can prevent the banknotes from being drawn out from the second storage space 37S.

Here, a position near the upper end of the first guide surface 41 and intersecting the closed shutter 45 (indicated by a thin broken line in the figure) is defined as a point P1. Further, among the banknotes handled by the banknote dispenser 1, a banknote bundle W in which banknotes having the shortest length in the short side direction (hereinafter referred to as the shortest banknote) are accumulated in a bundle is used as the shortest banknote bundle WS. And In the following, the shortest banknote bundle WS is also referred to as a shortest medium bundle.

In addition, in the reject cassette 17, the shortest banknote bundle WS rides on another banknote bundle WA, and the paper surface is brought into contact with the first guide surface 41 and the upper end thereof is positioned at the point P1. Suppose. Furthermore, a point where the lower end of the shortest banknote bundle WS is located at this time is defined as a point P2. The length DP, which is the distance between the point P1 and the point P2, is equivalent to the length of the short side of the shortest banknote.

If the reject cassette 17 closes the shutter 45 in this state, the shortest banknote bundle WS is sandwiched between the front end of the shutter 45 and the first guide surface 41. Therefore, the shutter 45 cannot be closed correctly, and this shortest The banknote bundle WS and other banknotes in the second storage space 37S may be extracted outside. In other words, the shortest banknote bundle WS at this time is at a position where obstruction of the intake hole 17H by the shutter 45 is obstructed.

Next, as shown by a thick broken line in the figure, the shortest banknote bundle WS has the lower end positioned at the point P2, while the upper end is positioned at a position away from the point P1 on the first guide surface 41 rearward and upward. In other words, it is assumed that the user is “standing” with the paper surface substantially in the front-rear direction. The shortest banknote bundle WS has an upper end located in the post-transport path lower space 28 on the bundle transport unit 3 side, and intersects with a trajectory (ie, a thin broken line in the drawing) through which the shutter 45 passes. Yes.

For this reason, when the shutter 45 moves forward so as to close the shutter 45, the shortest banknote bundle WS receives a forward force from the shutter 45 and falls forward so as to rotate about the point P2. As a result, the shortest banknote bundle WS is in a state where its upper end is positioned at the point P1, as shown by the solid line, and is sandwiched between the front end of the shutter 45 and the first guide surface 41 as described above. It is.

As described above, in the banknote dispensing machine 1, when the lower end of the shortest banknote bundle WS is located at the point P2, the paper surface is in contact with the first guide surface 41 or in a standing posture. The shutter 45 cannot be normally closed. Therefore, the banknote dispensing machine 1 defines the shortest arc CS, which is a virtual arc having a length DP as a radius around the point P2. Further, in the banknote dispensing machine 1, a point where the shortest arc CS intersects the front side surface 24F of the rear guide 24 is defined as a point Q1, and the lower end of the front side surface 24F is defined as a point Q2.

Then, in the banknote dispensing machine 1, if the upper end of the shortest banknote bundle WS is located downstream from the shortest arc CS (that is, the rear lower side, the portion indicated by the hatching in the drawing), the shutter 45 Can be closed normally. Further, in the banknote dispensing machine 1, if the upper end of the shortest banknote bundle WS is positioned upstream (ie, the front upper side) from the shortest arc CS, the shutter 45 cannot be normally closed, and the shortest banknote bundle WS is It is sandwiched between the first guide surface 41 and the first guide surface 41.

Therefore, in the banknote dispensing machine 1, if it can be detected that the upper end of the shortest banknote bundle WS is located above the shortest arc CS (that is, the hatched portion), the stage before the shutter 45 is actually closed is detected. Thus, it can be recognized in advance that the shutter 45 cannot be normally closed.

Here, in the banknote dispensing machine 1, when the optical sensor is arranged so that the linear optical axis is positioned below the shortest arc CS, the upper end of the shortest banknote bundle WS is positioned above the shortest arc CS. If so, the shortest banknote bundle WS crosses the optical axis and shields the detection light. For this reason, in the banknote dispenser 1, when the detection light is shielded by the shortest banknote bundle WS in this optical sensor, the upper end of the shortest banknote bundle WS is positioned at least above the optical axis of the optical sensor. In addition, the possibility of being located above the shortest arc CS becomes higher.

That is, in the banknote dispenser 1, if the optical sensor is arranged so that the optical axis is positioned below the shortest arc CS with respect to the shortest banknote WS, the shutter 45 can be normally closed by the shortest banknote WS. It can be detected without omission that there may be no possibility.

Next, among the banknotes handled by the banknote dispenser 1, the banknote bundle W formed by stacking banknotes having the longest length in the short side direction (hereinafter referred to as the longest banknote) in the form of a bundle is referred to as the longest banknote bundle. Let it be WL. In addition, as shown in FIG. 5B, it is assumed that the upper end of the longest banknote bundle WL is located at the point P1 in the banknote dispensing machine 1, and at this time, the position where the lower end of the longest banknote bundle WL is located is indicated by a point P2L. It is defined as This point P2L is located downstream of the point P2. In the following description, the length from the point P1 to the point P2L, that is, the length of the short side of the longest bank note is referred to as a length DPL.

Further, as in the case of the shortest banknote bundle WS, the longest arc CL is defined as a virtual arc having a length DPL as a radius around the point P2L where the lower end is located. Then, in the banknote dispensing machine 1, as in the case of the shortest banknote bundle WS, when the upper end of the longest banknote bundle WL is positioned above the longest arc CL, the longest banknote bundle WL is placed on the shutter 45 and the first guide surface 41. It will be sandwiched.

The longest arc CL is located on the upstream side of the shortest arc CS due to a geometrical relationship, and intersects the front side surface 24F of the rear guide 24 at a point Q1L located on the upstream side of the point Q1. For this reason, in the banknote dispenser 1, if the optical axis of the optical sensor is located below the shortest arc CS, this optical axis is also located below the longest arc CL.

Therefore, in the banknote dispensing machine 1, regardless of the length of the banknotes constituting the banknote bundle W, when the shutter 45 is closed by detecting the banknote bundle W whose upper end is located above the shortest arc CS. It can be reliably detected that the banknote bundle W may be sandwiched between the first guide surface 41.

Therefore, in the banknote dispenser 1, in the banknote bundle detection unit 60 described above, the inner side of the conveyance path rear lower space 28 and the communication space 43 on the optical axis X1 of the first detection light L1 and the optical axis X2 of the second detection light L2. The light emitting part 61, the light receiving part 62, and the prism 63 are arranged so that the entire range of the part is located downstream of the shortest arc CS.

Specifically, in the banknote dispensing machine 1, a point that intersects the first guide surface 41 (hereinafter referred to as an intersection point XP) of the optical axes X1 and X2 is positioned between the points P1 and P2. At the same time, in the banknote dispenser 1, a point that intersects the front side surface 24F of the rear guide 24 (hereinafter referred to as the intersection point XQ) of the optical axes X1 and X2 is positioned between the point Q1 and the point Q2. . Furthermore, in the banknote dispensing machine 1, the optical axes X1 and X2 are substantially parallel to the normal line of the first guide surface 41.

As a result, the banknote dispensing machine 1 reliably detects that the banknote bundle W is sandwiched between the first guide surface 41 when the shutter 45 is closed regardless of the length of the banknote. Can do. For convenience of explanation, in the following, a part of the banknote bundle W crosses at least one of the optical axes X1 and X2 as described above, and the banknote bundle between the first guide surface 41 when the shutter 45 is closed. A state in which there is a possibility of sandwiching W is referred to as a blockage abnormality preliminary state.

Incidentally, the banknote dispenser 1 may detect a banknote bundle W that is not sandwiched between the first guide surface 41 when the shutter 45 is closed, that is, a banknote bundle W that has no problem. However, the banknote dispenser 1 can reliably detect the banknote bundle W in the closed abnormal reserve state. That is, in the banknote dispenser 1, from the viewpoint of failing to detect the blockage abnormal preliminary state, so as to eliminate so-called detection omission, it is allowed to detect even when the shutter 45 can be closed, that is, to detect excessively. Yes.

[1-5. Effect]
In the above configuration, in the banknote dispenser 1 according to the first embodiment, the banknote bundle detection unit 60 is provided in the connection portion of the communication space 43 of the reject cassette 17 and the lower space 28 after the transport path of the bundle transport unit 3. (FIGS. 4 and 5). In particular, in the banknote dispenser 1, the light emitting unit 61 is arranged so that the optical axis X1 of the first detection light L1 and the optical axis X2 of the second detection light L2 in the banknote bundle detection unit 60 are positioned downstream of the shortest arc CS. The light receiving part 62 and the prism 63 are arranged (FIG. 5).

For this reason, as shown in FIG. 6, for example, the banknote bundle detection unit 60 has a banknote bundle W in a closed abnormal state, that is, regardless of the short sides of the banknotes constituting the banknote bundle W or the posture of the banknote bundle W. The banknote bundle W that may be pinched between the first guide surface 41 when the shutter 45 is closed can be detected without omission. As a result, when the banknote bundle detection unit 60 detects the banknote bundle W, the control unit 4 (FIG. 1), for example, notifies this to a staff member of the financial institution and prompts the maintenance work to be performed. Removal of the banknote bundle W detected as an abnormal standby state and storage in the second storage space can be performed.

As a result, in the banknote dispensing machine 1, when the reject cassette 17 is removed from the storage housing 10, the shutter 45 is not completely closed and the banknote bundle W is sandwiched between the first guide surface 41, It is possible to prevent the banknote bundle W and banknotes in the second storage space from being extracted by a malicious person. Further, in the banknote dispenser 1, while the shutter 45 cannot be completely closed, damage to each part due to the forcible removal of the reject cassette 17 from the storage housing 10 or the contact between the shutter 45 and the first guide surface 41. It is possible to prevent the banknote bundle W sandwiched therebetween from being caught and damaged by other parts.

Moreover, in the banknote dispenser 1, while attaching the light emission part 61 and the light-receiving part 62 which are electrical components among the components which comprise the banknote bundle detection part 60 to the rear guide 24 of the bundle conveyance unit 3, electricity supply and communication are unnecessary. The prism 63, which is an optical component, was attached to the first guide surface 41 of the reject cassette 17 (FIG. 4).

For this reason, in the banknote dispenser 1, it is not necessary to provide an electronic component on the side of the reject cassette 17 that is transported after being removed from the storage housing 10 (FIG. 1) and may be subjected to an impact, and the storage housing There is no need to provide a connector or the like for realizing electrical connection and disconnection between 10 and the reject cassette 17. As a result, in the banknote dispensing machine 1, the configuration of the reject cassette 17 can be simplified, and it can contribute to miniaturization and weight reduction. Therefore, the burden on workers and the like in transportation work and detachment work can be minimized. In addition, the cost of the reject cassette 17 can be reduced.

According to the above configuration, in the banknote dispensing machine 1 according to the first embodiment, the light emitting unit 61 and the light receiving unit 62 attached to the rear guide 24 of the bundle transport unit 3 and the first guide surface 41 of the reject cassette 17. The bill bundle detection unit 60 is configured by the prism 63 attached to the optical axis X1 and X2 so that the optical axes X1 and X2 are positioned downstream of the virtual shortest arc CS (FIG. 5). As a result, in the banknote dispenser 1, the reject cassette 17 to be attached and detached has a simple configuration, and there is a risk that the banknote bundle W in the closed abnormal reserve state, that is, may be sandwiched between the first guide surface 41 when the shutter 45 is closed. The presence of a banknote bundle W can be detected with certainty, and maintenance work can be promoted.

[2. Second Embodiment]
Compared with the banknote dispensing machine 1 according to the first embodiment, the banknote dispensing machine 101 (FIG. 1) according to the second embodiment includes a bundle conveyance unit 103 that replaces the bundle conveyance unit 3 and the control unit 4, and Although different in that the control unit 104 is provided, other points are configured in the same manner.

As shown in FIG. 7 corresponding to FIG. 4, the bundle conveyance unit 103 is different from the bundle conveyance unit 3 according to the first embodiment in that it has a bundle conveyance guide 122 instead of the bundle conveyance guide 22. However, the other points are configured similarly. As shown in FIG. 8, the bundle conveyance guide 122 is provided with a plurality of projecting portions 172 that project downward in a discrete manner at the rear portion of the lower surface of the main body portion 171. The protruding portion 172 as the protruding body is formed in a right triangle shape when viewed from the left-right direction, and the front side is substantially vertical while the rear side is inclined.

Similar to the control unit 4 according to the first embodiment, the control unit 104 is mainly configured by a CPU (not shown), and reads out and executes a predetermined program from a ROM, a flash memory, etc. (not shown). Processing such as processing is performed. However, in the control unit 104, the processing when the banknote bundle detection unit 60 detects the presence of the banknote bundle W is partially different from the control unit 4.

Specifically, when the banknote bundle detection unit 60 detects the banknote bundle W in the closed abnormal reserve state, the control unit 104 moves the bundle conveyance guide 122 to the rear side as shown in FIG. Make a round trip several times. As a result, the control unit 104 applies a force in the forward direction or the backward direction by bringing the protruding portion 172 into contact with the banknote bundle W, and this action causes the blockage abnormal reserve such as riding on the other banknote bundle W. The state is eliminated, that is, the state of traversing the optical axes X1 and X2 of the banknote bundle detection unit 60 is eliminated.

Here, the control unit 104 acquires the detection result from the banknote bundle detection unit 60 again, and confirms whether or not the banknote bundle W in the closed abnormal reserve state is detected. Here, when the presence of the banknote bundle W is no longer detected, the control unit 104 determines that the blockage abnormal reserve state has been eliminated, and does not notify the financial institution staff or the like. On the other hand, when the control unit 104 detects the presence of the banknote bundle W again, the control unit 104 determines that the blockage abnormal reserve state continues, notifies the staff of the financial institution, and removes the banknote bundle W. Prompt.

That is, when the banknote bundle detector 101 detects the presence of the banknote bundle W by the banknote bundle detection unit 60, the banknote dispenser 101 can eliminate the blockage abnormal reserve state by moving the bundle conveyance guide 122 in the front-rear direction. As a result, the banknote dispenser 101 can reduce the frequency with which maintenance work is performed by the staff of the financial institution, reduce the work load, and increase the so-called availability to the extent that the banknote dispenser 101 can be operated normally. Can do.

Further, the bundle conveyance guide 122 is provided with a protruding portion 172 only on the rear side of the lower surface of the main body portion 171. Thereby, when the bundle conveying guide 122 is moved to the front side and closes the upper side of the stacking space 16S in the stacking unit 16 (FIG. 1), the banknote discharged from the discharge unit is not adversely affected. It can be accumulated, and when it is moved to the rear side, it is possible to eliminate the blocking abnormal preliminary state.

In other respects, the banknote dispensing machine 101 can achieve the same effects as the banknote dispensing machine 1 according to the first embodiment.

According to the above configuration, in the banknote dispenser 101 according to the second embodiment, the banknote bundle detection unit 60 is provided, and the optical axes X1 and X2 are positioned downstream of the virtual shortest arc CS. (FIG. 5). As a result, the banknote dispenser 1 can reliably detect the presence of the banknote bundle W in the closed abnormally closed state while simplifying the reject cassette 17 to be attached and detached, and can prompt the execution of maintenance work. In addition to this, in the banknote dispensing machine 101, the protrusion 172 is provided on the lower surface of the main body 171 in the bundle conveyance guide 122 (FIG. 8). By moving the bundle conveying guide 122 in the front-rear direction, it is possible to eliminate the blockage abnormal preliminary state.

[3. Other Embodiments]
In the first embodiment described above, the first guide surface 41, which is the side surface of the communication space 43 that forms the second storage space 37S in the reject cassette 17 on the rear side of the intake hole 17H and communicates both. The case of tilting with respect to the vertical direction has been described (FIG. 2). However, the present invention is not limited to this. For example, the second storage space 37S is formed immediately below the intake hole 17H, the communication space 43 is formed along the vertical direction, and the first guide surface 41 is a plane along the vertical direction. It is also good. The same applies to the second embodiment.

Moreover, in 1st Embodiment mentioned above, in the banknote bundle detection part 60, the conveyance path back lower space 28 and the communication space 43 among the optical axes X1 of the 1st detection light L1 and the optical axes X2 of the 2nd detection light L2. A case has been described in which the entire range of the portion inside is positioned downstream of the shortest arc CS (FIG. 5A). However, the present invention is not limited to this. For example, the intersection XQ, that is, the point where the optical axes X1 and X2 intersect the front side surface 24F of the rear guide 24 is positioned above the point Q1, and a part of the optical axes X1 and X2 May be positioned above the shortest arc CS. Thereby, although there is a possibility that some of the cases where the banknote bundle W is in the closed abnormal reserve state may not be detected, the frequency of erroneously detecting the case where the banknote bundle W is not in the closed abnormal reserve state as a closed abnormal reserve state is reduced. Can be made. The same applies to the second embodiment.

Furthermore, in the first embodiment described above, the prism 63 is attached to the front lower side of the first guide surface 41, and through holes are respectively formed in the passing portions of the first detection light L1 and the second detection light L2. Stated. However, the present invention is not limited to this. For example, a relatively large through hole may be formed in the first guide surface 41 so that part or all of the prism 63 is embedded. In this case, since the optical axes X1 and X2 are along the normal direction of the first guide surface 41, the surface of the prism 63 is substantially parallel to the first guide surface 41. Accordingly, when at least a part of the banknote bundle W descends while sliding along the first guide surface 41, the prism 63 causes dust, dust, and the like attached to the surface thereof to be removed. The possibility that L1 and the second detection light L2 are attenuated or blocked by the dust or the like can be reduced. The same applies to the second embodiment.

Furthermore, in 1st Embodiment mentioned above, the advancing direction of the 1st detection light L1 which goes to the front lower direction in the banknote bundle detection part 60 is changed, and it is set as the 2nd detection light L2 which goes to a back upper direction. The case where the prism 63 is used as the optical component and is attached to the first guide surface 41 has been described. However, the present invention is not limited to this, and various optical components such as an optical component formed by combining two or more mirrors may be attached to the first guide surface 41. In short, it is only necessary to change the traveling direction of the first detection light L1 heading forward and downward to obtain the second detection light L2 heading backward and upward without requiring power supply or communication. The same applies to the second embodiment.

Furthermore, in the above-described first embodiment, the light emitting unit 61, the light receiving unit 62, and the prism 63 of the banknote bundle detecting unit 60 are respectively arranged at positions where the optical axes X1 and X2 overlap when viewed from the left-right direction. (FIG. 5A). However, the present invention is not limited to this. For example, the optical axis X2 may be positioned upstream or downstream with respect to the optical axis X1, and the angle of the optical axis X1 and the angle of the optical axis X2 with respect to the first guide surface 41 are set. They may be different from each other. That is, the optical axes X1 and X2 may be inclined at an angle different from the normal line of the first guide surface 41. The same applies to the second embodiment.

Further, in the above-described first embodiment, when the shutter 45 is opened, it moves (slides) to the rear side of the intake hole 17H, that is, the side opposite to the first guide surface 41 with the communication space 43 and the intake hole 17H interposed therebetween. The case of letting it was described. However, the present invention is not limited to this. For example, the shutter 45 may be moved to the front side of the intake hole 17H when opened, or may be rotated by a variety of other methods such as rotating around a predetermined rotation axis. The shutter 45 may be opened and closed with respect to the intake hole 17H. The same applies to the second embodiment.

Furthermore, in the above-described second embodiment, the case where the protrusions 172 provided on the bundle conveyance guide 122 are formed in a right triangle shape when viewed from the left-right direction has been described. However, the present invention is not limited to this, and may have various shapes such as an isosceles triangle shape and a semi-elliptical shape when viewed from the left-right direction.

Furthermore, in the first embodiment described above, the case where the present invention is applied to the banknote dispensing machine 1 that stacks banknotes, which are paper-like media, in a bundle and dispenses them as banknote bundles W has been described. However, the present invention is not limited to this, and may be applied to various apparatuses that handle a bundle of media formed by stacking various paper-like media such as securities and cash vouchers, gift certificates and admission tickets. The same applies to the second embodiment.

Furthermore, the present invention is not limited to the above-described embodiments and other embodiments. That is, the scope of the present invention extends to embodiments in which some or all of the above-described embodiments and other embodiments described above are arbitrarily combined, and embodiments in which some are extracted. It is.

Furthermore, in the above-described first embodiment, the case where the medium transaction apparatus is configured by the storage casing 10 and the bundle transport unit 3 as the main body and the reject cassette 17 as the medium storage has been described.
