Then, the light reflected by the reflecting member is received by the light receiving unit, and the state of the integrated member is detected. When the reflection member is provided on the accumulation member, the thickness of the case can be reduced as compared with the case where the reflection member is provided on the enclosure below the accumulation member, for example. As a result, the bill processing apparatus can be downsized.

  Moreover, in said banknote processing apparatus, the said light emission part and the said reflection member may be arrange | positioned so that the light which goes to the said reflection member from the said light emission part may cross | intersect the moving direction of the said integration | stacking member.

  Further, in the banknote handling apparatus, the amount of light reflected by the reflecting member when the stacking member is positioned away from the light emitting unit is the amount of light reflected by the reflecting member when the stacking member is positioned near the light emitting unit. It may be greater than the amount of light reflected by the member.

  In the bill processing apparatus, the light emitting unit and the reflecting member may be arranged so that light traveling from the light emitting unit to the reflecting member is parallel to a moving direction of the stacking member.

  In the banknote handling apparatus, the light emitting unit is a light emitting sensor, and further includes a control unit that controls an output of the light emitting sensor, and the control unit is configured such that the stacking member is located near the light emitting sensor. In this case, the output of the light emitting sensor may be reduced, and the output of the light emitting sensor may be increased when the integrated member is located away from the light emitting sensor.

  In the banknote handling apparatus, the light receiving unit is a light receiving sensor, and further includes a control unit that controls sensitivity of the light receiving sensor, and the control unit is configured such that the stacking member is located near the light receiving sensor. In this case, the sensitivity of the light receiving sensor may be reduced, and the sensitivity of the light receiving sensor may be increased when the integrated member is located away from the light receiving sensor.

  In the banknote handling apparatus, the stacking member may have a stacking surface for stacking the banknotes, and the reflecting member may be provided so as to be exposed on the stacking surface.

  In the above description, the coin processing device according to the present invention is a cash change machine connected to a register or the like, but is not limited thereto. For example, the coin processing device may be an automatic transaction device typified by ATM (Automated Teller Machine) provided in a branch of a financial institution or the like.

(1-2. Configuration of banknote deposit / withdrawal unit)
An example of the configuration of the banknote deposit / withdrawal unit 100 according to the first embodiment will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of the configuration of the banknote deposit / withdrawal unit 100 according to the first embodiment.

  The banknote depositing / withdrawing unit 100 of the banknote processing unit 30 combines the function of a depositing slot for inserting deposited banknotes and the function of a dispensing slot for discharging dispensed banknotes. Thus, it becomes possible for the banknote processing unit 30 (cash processing apparatus 10) to be reduced in size because the banknote depositing / withdrawing unit 100 also functions as a depositing port and a dispensing port.

  As shown in FIG. 2, the bill depositing / dispensing unit 100 includes a frame unit 101, a stage 102, a stage arm 103, a picker roller 104, a separation roller 105, an upper guide 106, a bill stopper 114, and a light emitting sensor. 121, a light receiving sensor 122, and a prism 124.

  The frame unit 101 forms a skeleton of the banknote deposit / withdrawal unit 100. A space for depositing / withdrawing bills is formed inside the frame portion 101. Further, the shutter 32 (FIG. 1) opens and closes with respect to the frame unit 101.

  The stage 102 has a function of accumulating banknotes. The stage 102 includes a stacking surface 102a for stacking banknotes. For example, the stage 102 accumulates deposited banknotes inserted by the operator and dispensed banknotes discharged from the apparatus on the accumulation surface 102a. The stage 102 can be moved in the vertical direction by the stage arm 103.

  The stage arm 103 is connected to a connecting portion 102b at the lower part of the stage 102, and is rotatable about a rotation shaft 103a. The stage arm 103 rotates in response to power from the drive mechanism, thereby moving the stage 102 up and down in the vertical direction (Z direction in FIG. 2). At this time, the stage 102 moves along guides located on both sides of the stage 102.

  The stage 102 moves between a plurality of positions. Specifically, the stage 102 moves between a standby position, an accumulation position, and a separation position as shown in FIG. Here, the standby position corresponds to a first position where the inserted deposited banknotes are accumulated, the separation position corresponds to a second position where the accumulated deposited banknotes are separated and fed into the apparatus, and the accumulation position is the apparatus. This corresponds to the third position for collecting the withdrawal banknotes discharged from the inside.

  FIG. 3 is a diagram for explaining a plurality of positions of the stage 102 according to the first embodiment. 3A shows the standby position of the stage 102, FIG. 3B shows the separation position of the stage 102, and FIG. 3C shows the accumulation position of the stage 102.

  The standby position of the stage 102 is located at the lowest position in the vertical direction (Z direction in FIG. 2). As shown in FIG. 3A, the stage 102 is positioned at the standby position when the operator inserts the deposited banknote S at the time of depositing. Further, the stage 102 is located at a standby position when an operator pulls out a withdrawal bill at the time of withdrawal.

  The separation position of the stage 102 is located at the uppermost position in the vertical direction. As shown in FIG. 3B, the stage 102 is positioned at the separation position when the deposited banknote S is separated by the picker roller 104 and the separation roller 105 and taken into the apparatus. The received deposited banknote is stored in, for example, a cassette. Note that the banknote S on the stage 102 is pressed against the picker roller 104 when the stage 102 is located at the separation position. At this time, an appropriate frictional force is generated between the bill and the picker roller 104.

  The accumulation position of the stage 102 is located between the standby position and the separation position in the vertical direction. As shown in FIG. 3C, the stage 102 is positioned at the stacking position when the withdrawal bill S is discharged from the inside of the apparatus (for example, a cassette for storing bills).

  The picker roller 104 is a pickup roller that picks up the banknote on the stage 102 located at the separation position shown in FIG. The separation roller 105 separates bills picked up by the picker roller 104 one by one and feeds them into the apparatus. The separation roller 105 and the picker roller 104 are connected by an idle gear, and rotate in the same direction upon receiving a driving force.

  The upper guide 106 supports the picker roller 104 and is rotatably connected to the shaft 105 a of the separation roller 105. The upper guide 106 and the picker roller 104 rotate together around the shaft 105 a of the separation roller 105. A spring 109 is provided above the upper guide 106 to urge the upper guide 106 toward the stage 102. When the stage 102 is positioned at the separation position, the upper guide 106 is rotated upward against the urging force of the spring 109 by pressing the picker roller 104 via a bill.

  A convex portion 106 a is formed at the tip of the upper guide 106 on the spring 109 side. The convex part 106a is for detecting the separation position of the stage 102 by shielding the light of the sensor 108 when the stage 102 is located at the separation position. The convex portion 106a is located at a position where the light of the sensor 108 is not shielded when the stage 102 is located at the standby position or the accumulation position.

  A stop roller 111 and a tongue piece 112 are provided at a position facing the separation roller 105. The stop roller 111 and the tongue piece 112 are provided coaxially and rotate only in the direction in which the banknotes are discharged onto the stage 102 and accumulated by the one-way clutch. Further, the stop roller 111 and the tongue piece 112 are biased toward the separation roller 105 by a spring.

  The bill stopper 114 has a function of preventing banknotes from jumping out of a deposit / withdrawal port formed by the frame unit 101 at the time of withdrawal. The bill stopper 114 can be moved in the vertical direction by a drive mechanism. The bill stopper 114 is positioned so as to block the deposit / withdrawal port only when the withdrawal banknotes are accumulated on the stage 102 (during withdrawal accumulation). Note that the bill stopper 114 is retracted to a position below the stage 102 at times other than the withdrawal accumulation. The shutter 32 (FIG. 1) described above may also function as the bill stopper 114.

  The light emission sensor 121 has a function of a light emitting unit that emits light toward the stage 102 in order to detect a banknote on the stage 102. The light emission sensor 121 is fixedly disposed so as to face the stage 102 above the stage 102.

  The light receiving sensor 122 has a function of a light receiving unit that receives light reflected by the prism 124. The light receiving sensor 122 is fixedly disposed so as to be adjacent to the light emitting sensor 121 above the stage 102. The light receiving sensor 122 receives the light whose direction is reversed by the prism 124.

  The prism 124 has a function of a reflecting member that reflects light emitted from the light emitting sensor 121. The prism 124 is provided on the stage 102. As a result, the prism 124 moves up and down together with the stage 102.

  The light emitting sensor 121, the light receiving sensor 122, and the prism 124 are respectively provided on both ends of the stage 102 in the longitudinal direction (longitudinal direction of banknotes). Thereby, the breakage of the banknote on the stage 102 can be detected.

  FIG. 4A is a diagram for explaining the prism 124 provided on the stage 102. FIG. 4B is a diagram illustrating the positions of the stage 102, the light emission sensor 121, and the light reception sensor 122. 4B is a schematic view of the stage 102 and the like viewed from the Y direction (front side of the apparatus) shown in FIG. The light emitting sensor 121 and the light receiving sensor 122 may be arranged in a line parallel to the longitudinal direction of the banknote as shown in FIG. 4B, or may be arranged side by side so as to intersect the longitudinal direction of the banknote. .

  As shown in FIGS. 4A and 4B, the prism 124 has an incident surface 124a, a light guide part 124b, and an output surface 124c. The light emitted from the light emitting sensor 121 is introduced into the incident surface 124a. The light guide unit 124b reflects the light introduced from the incident surface 124a by the reflecting surface and guides it to the emitting surface 124c. The emission surface 124c emits the light reflected by the light guide unit 124b. The light emitted from the emission surface 124 c is received by the light receiving sensor 122.

  The entrance surface 124a and the exit surface 124c of the prism 124 are provided so as to be exposed to the integration surface 102a of the stage 102 as shown in FIG. 4A. Thereby, the entrance surface 124a and the exit surface 124c are cleaned by the banknotes stacked on the stage 102. For this reason, it is not necessary to provide a dedicated component for cleaning the entrance surface 124a and the exit surface 124c. In the above description, both the entrance surface 124a and the exit surface 124c are exposed to the integration surface 102a. However, the present invention is not limited to this, and only one of the entrance surface 124a and the exit surface 124c may be exposed. good. Even in such a case, the exposed surface is cleaned with banknotes.

  By the way, in 1st Embodiment, the light emission sensor 121, the light reception sensor 122, and the prism 124 are arrange | positioned as follows. That is, the prism 124 provided on the stage 102 is arranged at a position away from directly below the light emitting sensor 121 and the light receiving sensor 122 as shown in FIG. The light emitting sensor 121, the light receiving sensor 122, and the prism 124 are arranged obliquely with respect to the vertical direction. For this reason, the light traveling from the light emitting sensor 121 toward the prism 124 intersects the moving direction of the stage 102.

  In the first embodiment, the prism 124 is positioned on the optical axis of the light emitted from the light emitting sensor 121 when the stage 102 is positioned away from the light emitting sensor 121, and the stage 102 is close to the light emitting sensor 121. When positioned, the light emitted from the light emitting sensor 121 is shifted from the optical axis. For this reason, the amount of light reflected by the prism 124 when the stage 102 is located at the standby position is larger than the amount of light reflected by the prism 124 when the stage 102 is located at the separation position or the accumulation position. This makes it possible to maintain the light receiving level of the light receiving sensor 122 that receives the light emitted from the light emitting sensor 121 and reflected by the prism 124 when the stage 102 is positioned at the standby position, the separation position, and the accumulation position. .

(About the light receiving level of the light receiving sensor 122)
The light receiving level of the light receiving sensor 122 that receives the light emitted from the light emitting sensor 121 and reflected by the prism 124 when the stage 102 is located at the standby position, the separation position, and the accumulation position will be described.

  When the stage 102 is positioned at the standby position, the prism 124 is positioned on the optical path (optical axis) in the traveling direction of the light emitted from the light emitting sensor 121 as described above. Similarly, the light receiving sensor 122 is positioned on the optical path in the traveling direction of the light reflected by the prism 124. For this reason, the light emitted from the light emitting sensor 121 is reflected by the prism 124 and received by the light receiving sensor 122 at a high light receiving level (for convenience of explanation, the light receiving level is 100). As a result, the inserted bill on the stage 102 at the standby position can be accurately detected.

When the stage 102 is located at the separation position, the prism 124 is displaced from the optical path (optical axis) in the traveling direction of the light emitted from the light emitting sensor 121 as described above. Since the amount of light reflected by the prism 124 is reduced by this amount of deviation, the light receiving level of the light receiving sensor 122 is also reduced compared to the standby position (for example, it is assumed that the level A is reduced). On the other hand, when the stage 102 is located at the separation position, the distance from the light emitting sensor 121 (light receiving sensor 122) is shortened. Usually, as the distance is shorter, the amount of light tends to increase. Therefore, the light receiving level of the light receiving sensor 122 also increases compared to the standby position (for example, it is assumed that the level B increases). Therefore, when the stage 102 is located at the separation position, the light receiving level of the light receiving sensor 122 is expressed by the following equation (1).
Light reception level = 100−A + B Expression (1)
Note that 100 in the above formula (1) is a light reception level when the stage 102 is positioned at the standby position.

  In the first embodiment, the light reception level A for the decrease in Expression (1) and the light reception level B for the increase are substantially the same, so that the light reception when the stage 102 is located at the separation position is performed. The light reception level of the sensor 122 is the same as the light reception level of the light reception sensor 122 in which the stage 102 is positioned at the standby position. For this reason, even if the position of the stage 102 fluctuates, the same light receiving level can be maintained, and as a result, the banknote can be detected with high accuracy.

  Even when the stage 102 is located at the accumulation position, the prism 124 is deviated from the optical path (optical axis) in the traveling direction of the light emitted from the light emitting sensor 121 as in the separation position. Decrease compared to position. On the other hand, when the stage 102 is located at the accumulation position, the distance to the light emitting sensor 121 (light receiving sensor 122) is shortened, so that the light receiving level of the light receiving sensor 122 is also increased compared to the standby position. For this reason, when the stage 102 is located at the accumulation position, the light receiving level of the light receiving sensor 122 is expressed in the same manner as the above-described equation (1).

  At the integration position, the light reception level A of the decrease is substantially the same as the light reception level B of the increase, so that the light reception level of the light reception sensor 122 when the stage 102 is located at the integration position is It becomes the same as the light receiving level of the light receiving sensor 122 when it is located at the standby position. For this reason, even if the position of the stage 102 fluctuates, the same light receiving level can be maintained, and as a result, the banknote can be detected with high accuracy.

  In the above description, the stage 102 on which the prism 124 is disposed is provided in the banknote deposit / withdrawal unit 100, but the present invention is not limited to this. For example, the stage on which the prism is arranged may be provided in a cassette for storing deposited banknotes in the cash processing apparatus 10.

  In the above description, the prism 124 is described as an example of the reflecting member that reflects the light emitted from the light emitting sensor 121. However, the present invention is not limited to this. The reflection member may be, for example, a reflection plate as long as the direction of light can be reversed.

(1-3. Functional configuration of cash processing apparatus)
An example of the functional configuration of the cash processing apparatus 10 will be described with reference to FIG. FIG. 5 is a block diagram illustrating an example of a functional configuration of the cash processing apparatus 10.

  The cash processing apparatus 10 includes a control unit 70 that controls the overall operation of the cash processing apparatus 10. For example, the control unit 70 controls the operation of the banknote deposit / withdrawal unit 100. As shown in FIG. 5, the control unit 70 includes a control unit 72 and a storage unit 74.

  The controller 72 controls the movement of the stage 102 when depositing or dispensing banknotes. Further, the control unit 72 controls the operation of the light emitting sensor 121 and the light receiving sensor 122. For example, the control unit 72 detects the presence / absence of banknotes on the stage 102 by the light emitting sensor 121 and the light receiving sensor 122. And the control part 72 controls the movement of the stage 102 according to the detection of the presence or absence of the banknote on the stage 102. FIG. Note that the control unit 72 may control the output of the light emitting sensor 121 and the sensitivity of the light receiving sensor 122.

  The storage unit 74 stores a program executed by the control unit 72. The storage unit 74 stores various data necessary for the operation of the cash processing apparatus 10. For example, the storage unit 74 may store a set value for the output of the light emitting sensor 121 and a set value for the sensitivity of the light receiving sensor 122.

(1-4. Example of operation of banknote deposit / withdrawal unit)
Below, it demonstrates in order of the operation example of the banknote depositing / withdrawing part 100 at the time of payment of a banknote, and the operation example of the banknote depositing / withdrawing part 100 at the time of payment of a banknote. In addition, operation | movement of the banknote depositing / withdrawing part 100 is implement | achieved when the control part 72 of the control unit 70 runs the program memorize | stored in the memory | storage part 74. FIG.

(Operation example when depositing)
First, an operation example of the banknote deposit / withdrawal unit 100 when depositing banknotes will be described.

  Here, it is assumed that the stage 102 is located at the standby position (FIG. 3A). The operator inserts the deposited banknote into the stage 102 located at the standby position. When the inserted bill is detected by the light emitting sensor 121, the light receiving sensor 122, and the prism 124, the control unit 72 raises the stage 102 and moves it to the separation position (FIG. 3B). Then, the control unit 72 causes the picker roller 104 and the separation roller 105 to separate the banknotes on the stage 102 located at the separation position one by one, and takes them into the apparatus. The taken banknote is stored in, for example, a cassette.

  Next, the control unit 72 detects the presence or absence of banknotes on the stage 102 located at the separation position by the light emitting sensor 121, the light receiving sensor 122, and the prism 124. As described above, even if the stage 102 is located at the separation position, the light receiving level of the light receiving sensor 122 can be maintained similarly to the standby position, so that the presence or absence of banknotes on the stage 102 can be detected appropriately.

  Then, when it is detected that there are no banknotes on the stage 102, the control unit 72 determines that all banknotes have been taken into the apparatus, and moves the stage 102 to a standby position, for example. Even if the position of the stage 102 fluctuates, the presence / absence of banknotes can be detected appropriately, so that control for moving the stage 102 to the standby position can be performed at an appropriate timing.

  In addition, when a banknote is thrown in on the stage 102 or when the banknote on the stage 102 is drawn out, the entrance surface 124a and the exit surface 124c of the prism 124 are cleaned by the banknote. As a result, it is possible to prevent erroneous detection of banknotes due to dust and the like adhering to the prism 124.

(Operation example when withdrawing)
The operation example of the banknote depositing / withdrawing unit 100 when dispensing banknotes will be described.

  Here, it is assumed that the stage 102 is located at the accumulation position (FIG. 3C). When the operator designates the number of dispensed banknotes, the control unit 72 causes the stage 102 to eject the dispensed banknotes conveyed from within the apparatus (for example, a cassette). Thereby, banknotes are stacked on the stage 102 located at the stacking position.

  Next, the control unit 72 detects the presence or absence of banknotes on the stage 102 located at the stacking position by the light emitting sensor 121, the light receiving sensor 122, and the prism 124. As described above, even when the stage 102 is located at the stacking position, the light receiving level of the light receiving sensor 122 can be maintained as in the standby position, so that the presence or absence of banknotes on the stage 102 can be detected appropriately.

  Then, when it is detected that there is a banknote on the stage 102, the control unit 72 determines that the banknote has been discharged, and moves the stage 102 to a standby position, for example. Thereby, the operator can extract the withdrawal banknote discharged | emitted by the stage 102. FIG.

  When the withdrawal bill is discharged onto the stage 102, the entrance surface 124a and the exit surface 124c of the prism 124 are cleaned by the withdrawal bill. As a result, it is possible to prevent erroneous detection of banknotes due to dust and the like adhering to the prism 124.

(1-5. Effectiveness of the first embodiment)
In the cash processing apparatus 10 according to the first embodiment described above, the prism 124 that reflects the light emitted from the light emitting sensor 121 is provided on the moving stage 102. Thereby, size reduction of the cash processing apparatus 10 is attained. Here, it demonstrates, contrasting with the comparative example shown in FIG.

  FIG. 6 is a diagram illustrating a configuration of the banknote depositing / withdrawing unit 900 according to the comparative example. 6A shows the standby position of the stage 902, FIG. 6B shows the separation position of the stage 902, and FIG. 6C shows the accumulation position of the stage 902. Also in the banknote depositing / withdrawing unit 900 according to the comparative example, the stage 902 for stacking banknotes moves between a standby position, a separation position, and a stacking position. On the other hand, in the banknote deposit / withdrawal unit 900, a prism 924 that reflects light emitted from the light emitting sensor 921 is built in the attachment unit 930 of the frame unit 901 below the stage 902. For this reason, the frame part 901 is also thickened by the thickness of the attachment part 930, and the length of the banknote depositing / withdrawing part 900 in the vertical direction (Z direction in FIG. 6) is increased.

  On the other hand, in the first embodiment, by providing the prism 124 on the stage 102, an attachment portion for incorporating the prism 124 into the frame portion 101 is not necessary, and thus the thickness of the frame portion 101 can be reduced. As a result, the vertical length of the banknote deposit / withdrawal unit 100 can be reduced, and the cash processing apparatus 10 can be downsized.

  In the comparative example shown in FIG. 6, dust 950 such as paper dust may adhere to the prism 924. If the dust 950 adheres to the prism 924 (for example, the incident surface or the exit surface of the prism 924), it may cause a false detection. Therefore, it is necessary to provide a cleaning member for cleaning the prism 924.

  On the other hand, in the first embodiment, the incident surface 124 a and the emission surface 124 c of the prism 124 exposed to the stage 102 are cleaned by the banknotes accumulated on the stage 102. Accordingly, it is possible to prevent erroneous detection caused by dust or the like adhering to the incident surface 124a and the emission surface 124c without providing a cleaning member.

  Furthermore, in the first embodiment, the light emission sensor 121 and the prism 124 are arranged so that light traveling from the light emission sensor 121 to the prism 124 intersects the moving direction of the stage 102. Thereby, even if the position of the stage 102 fluctuates, the light receiving level of the light receiving sensor 122 can be maintained, so that the banknotes on the stage 102 can be detected appropriately.

<2. Second Embodiment>
The structure of the banknote depositing / withdrawing part 100 which concerns on 2nd Embodiment is demonstrated referring FIG.7 and FIG.8.

  FIG. 7 is a diagram illustrating a configuration of the banknote depositing / dispensing unit 100 according to the second embodiment. FIG. 8 is a diagram for explaining a plurality of positions of the stage 102 according to the second embodiment. 8A shows the standby position of the stage 102, FIG. 8B shows the separation position of the stage 102, and FIG. 8C shows the accumulation position of the stage 102.

  Also in the second embodiment, the prism 124 is provided on the stage 102. Specifically, as in the first embodiment, the entrance surface 124 a and the exit surface 124 c of the prism 124 are provided so as to be exposed to the integration surface 102 a of the stage 102. For this reason, also in 2nd Embodiment, size reduction of an apparatus is realizable. Moreover, the entrance surface 124a and the exit surface 124c are cleaned by the banknote.

  On the other hand, in the first embodiment described above, the light emitting sensor 121 and the prism 124 are arranged so that the optical axis between the light emitting sensor 121 and the prism 124 intersects the moving direction of the stage 102. On the other hand, in the second embodiment, the light emission sensor 121 and the prism 124 are arranged so that the light traveling from the light emission sensor 121 to the prism 124 is parallel to the moving direction of the stage 102 as shown in FIG. Has been.

  In the case of the configuration described above, unlike the first embodiment, the light receiving level of the light receiving sensor 122 differs depending on the position of the stage 102. That is, the light receiving level of the light receiving sensor 122 increases as the stage 102 approaches the light emitting sensor 121. Therefore, in the second embodiment, the control unit 72 performs the following control so that the light receiving level of the light receiving sensor 122 is maintained even if the position of the stage 102 changes.

  First, the control unit 72 reduces the output of the light emission sensor 121 when the stage 102 is located near the light emission sensor 121, and increases the output of the light emission sensor 121 when the stage 102 is located away from the light emission sensor 121. . Further, the control unit 72 decreases the sensitivity of the light receiving sensor 122 when the stage 102 is located near the light receiving sensor 122, and increases the sensitivity of the light receiving sensor 122 when the stage 102 is positioned away from the light receiving sensor 122. .

  FIG. 9 is a diagram illustrating a setting table for the output of the light emitting sensor 121 and the sensitivity of the light receiving sensor 122 according to the second embodiment. The setting table is stored in the storage unit 74 (FIG. 5), for example. As shown in FIG. 9, the outputs a1, a2, and a3 of the light emitting sensor 121 and the sensitivities b1, b2, and b3 of the light receiving sensor 122 are set for each standby position, separation position, and stacking position of the stage 102, respectively. Here, the output a1 of the light emitting sensor 121 at the standby position, the output a2 at the accumulation position, and the output a3 at the separation position have a relationship of a1> a2> a3. The sensitivity b1 of the light receiving sensor 122 at the standby position, the sensitivity b2 at the integration position, and the sensitivity b3 at the separation position are in a relationship of b1> b2> b3. That is, the closer the stage 102 is to the light emitting sensor 121, the smaller the output of the light emitting sensor 121 and the sensitivity of the light receiving sensor 122 are.

  In the second embodiment, the outputs a <b> 1 to a <b> 3 and the sensitivities b <b> 1 to b <b> 3 are set so that the light reception level of the light reception sensor 122 at each position of the stage 102 is the same. Thereby, even if the position of the stage 102 fluctuates, the light receiving level can be maintained, and as a result, the presence or absence of banknotes at each position of the stage 102 can be detected with high accuracy.

  In the above description, the output of the light emitting sensor 121 and the sensitivity of the light receiving sensor 122 are changed according to the position of the stage 102, but the present invention is not limited to this. For example, only one of the output of the light emitting sensor 121 and the sensitivity of the light receiving sensor 122 may be varied according to the position of the stage 102. Even in such a case, the light reception level can be maintained even if the position of the stage 102 fluctuates.

  Also in the first embodiment, similarly to the second embodiment, the outputs a1 to a3 of the light emitting sensor 121 and the sensitivities b1 to b3 of the light receiving sensor 122 may be varied according to the position of the stage 102. . Thereby, even if the position of the stage 102 fluctuates, the light reception level can be maintained.

  In the above description, the light receiving sensor 122 is provided above the stage 102 so as to be adjacent to the light emitting sensor 121. However, the present invention is not limited to this. For example, the light receiving sensor 122 may be provided on the stage 102, and the outputs a1 to a3 of the light emitting sensor 121 and the sensitivities b1 to b3 of the light receiving sensor 122 may be varied depending on the position of the stage 102.

  The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims.
