And a control unit 41.

  The bar storage 14 of the first embodiment is provided with a housing 50 on which the money depositing / dispensing machine 13 is mounted, and can be pulled out from the housing 50 to the operator side and stored in the housing 50. And a bar metal tray 51.

  Here, the bar metal of each denomination stored in the bar metal tray 51 will be described. As shown in the chart of FIG. 3, the types of bar metal are currently packaged by collecting 50 yen 1 yen bars and 50 yen brass coins in Japan. 50 yen bar, 50 yen coins, 50 yen coins, 50 yen coins, 50 yen coins, 50 yen coins, 50 yen coins, 50 yen coins. 100 yen bars, 50 first 500 yen brass coins, and 50 second 500 yen nickel brass coins. Gold may be handled.

  Looking at the material, the 50 yen, 100 yen and the first 500 yen have the same components and the same conductivity, while the 1 yen, 5 yen, 10 yen and the second 500 yen. Each has a different component and a different conductivity. In terms of diameter, the first 500 yen and the second 500 yen are the same, while the 1, 5, 10, 50, and 100 yen are different from the others. Furthermore, when we look at the weight in the case of a bar, the difference between the first 500 yen bar and the second 500 yen bar is small, but all are different. Furthermore, when looking at the length of the bar, the 1-yen bar, the 5-yen bar and the 10-yen bar are the same and shorter than the other, while the 100-yen bar is a 1-yen bar, It is slightly longer than the 5-yen bar and the 10-yen bar, the 50-yen bar is longer, and the first 500-yen bar and the second 500-yen bar are the same and longer.

  As shown in FIG. 1, the housing 50 has a substantially rectangular parallelepiped box shape with a low height, and an opening 52 is formed on the front surface on the operator side.

  The bar tray 51 is provided with a pair of slide rails (not shown) that extend in the front-rear direction on the outer sides of the left and right sides, and is slidably supported by the housing 50 via these slide rails. . 2 is turned on by the bar metal tray 51 in a state in which the bar metal tray 51 is housed in the housing 50, and is turned off at other positions. ) 58 and a drawer switch (storage detection means) 59 that is turned on by the bar metal tray 51 when it is located at a predetermined position where it is pulled out from the housing 50 and turned off at other positions. These are connected to a bar storage control unit 60 (bar metal presence / absence denomination identifying means, confirmation means, management means, storage detection means, power supply monitoring means) 60. When the close position switch 58 is turned on within a predetermined time after the drawer switch 59 is switched from OFF to ON, the bar storage controller 60 starts from the opened state in which the bar tray 51 is pulled out of the housing 50. Detects opening / closing switching to the closed state in which it is stored. Further, when the drawer switch 59 is turned on within a predetermined time after the closing position switch 58 is switched from on to off, the switching of the bar tray 51 with respect to the housing 50 from the closed state to the open state is detected.

  As shown in FIG. 4, the bar tray 51 is provided with a plurality of set portions S capable of setting all types of bar metal, divided into two rows on the left and right sides. . The plurality of set portions S on one side in the left-right direction are set in a posture in which any one of the metal bars B1, B5, B10, B50, B100, B500 has its axis line along the left-right direction. Each of them is arranged in parallel in the pull-out direction so that the positions in the left-right direction coincide with each other. In addition, the plurality of set portions S on the other side in the left-right direction are also set such that any one of the metal bars B1, B5, B10, B50, B100, B500 has its axis line along the left-right direction. Thus, they are arranged side by side in the drawing direction with their positions in the left-right direction matched. Here, the number of the set parts S is the same in two rows on one side and the other side in the left-right direction. Further, the left and right set portions S having the same arrangement order from the front side in the pull-out direction have the same position in the pull-out direction. As a result, the entire set portions S on one side in the left-right direction and the left-right direction The position in the pull-out direction is made to coincide with the entirety of the plurality of other set portions S on the other side.

  As shown in FIG. 5, each set portion S described above has a concave shape that is recessed downward, and is provided so as to be individually movable up and down, and has a cylindrical surface shape that is larger in diameter than the outer diameter of the largest outer diameter metal rod. And a pair of end surfaces 66 rising from the both sides in the axial direction of the bottom surface 65 at intervals longer than the length of the longest metal rod, and having an opening that is rectangular in plan view. ing. FIG. 5 illustrates a state in which a 10-yen coin bar B10 is set.

  Each set unit S of the bar tray 51 is provided with a weight sensor (bar bar presence / absence / denomination identifying means) 70a for detecting the weight of the set bar.

  The outputs of all the weight sensors 70a can be identified by scanning in a time division manner using a multiplexer circuit or the like, and are transmitted to the bar storage controller 60. Here, all the set parts S are not set with the denominations of the metal bars B1, B5, B10, B50, B100, and B500 to be set. For this reason, in the bar storage control unit 60, the weights detected by the respective weight sensors 70a provided in all the set units S are the set denominations of the metal bars B1, B5, B10, B50, B100, B500. Based on whether or not there is a match within a predetermined tolerance set for each denomination for each reference weight, the presence or absence of a bar and the set denomination of the bar are identified.

  That is, if the weight sensor 70a does not detect a weight equal to or greater than a predetermined value, it is determined that there is no bar. If the weight sensor 70a detects a weight equal to or greater than the predetermined value, the detected weight is set to the value of the one-yen bar B1. Reference weight, reference weight of 5-yen bar B5, reference weight of 10-yen bar B10, reference weight of 50-yen bar B50, reference weight of 100-yen bar B100 and reference weight of 500-yen bar B500 If the deviation from the standard weight of any one denomination is within the preset allowable range for each denomination, it is determined that there is a bar of that denomination, and the standard weight of any denomination is On the other hand, if the error is not within the allowable range, it is determined that the state is abnormal (the set state of an object other than a bar or the set state of an abnormal bar).

  For example, if the weight detected by the weight sensor 70a is within an allowable range set for the 1-yen bar B1 with respect to the reference weight of the 1-yen bar B1, it is determined that the 1-yen bar B1 exists. If the error from the reference weight of the 5-yen bar B5 is within the allowable range set for the 5-yen bar B5, it is determined that the 5-yen bar B5 is present, and the difference from the reference weight of the 10-yen bar B10 If the error is within the allowable range set for the 10-yen bar B10, it is determined that there is a 10-yen bar B10, and the error from the reference weight of the 50-yen bar B50 is set for the 50-yen bar B50. If it is within the allowable range, it is determined that there is a 50-yen bar B50, and if the error from the reference weight of the 100-yen bar B100 is within the allowable range set for the 100-yen bar B100, the 100-yen bar It is judged that there is B100, and the error from the reference weight of 500 yen bar B500 is 50 Yen coin 500 yen if within the allowable range set with respect to B500 coin bar B500 is determined that there is. And the bar metal storage control part 60 detects the amount of bar metal in the bar metal storage 14 based on the detection result of all the weight sensors 70a. Note that the tolerance range of each reference weight error is set so as not to overlap with the tolerance range of other reference weight errors.

  Here, the bar storage control unit 60 is communicably connected to the POS register control unit 20, and the POS register control unit 20 further includes a banknote deposit / withdrawal control unit 36 and a coin deposit / withdrawal control unit 41. It is connected so that it can communicate. The POS cash register control unit 20 receives power supply from an external power source, and supplies power to the banknote deposit / withdrawal control unit 36, the coin deposit / withdrawal control unit 41, and the bar storage control unit 60, respectively. The POS cash register control unit 20 is communicably connected to a system management device 71 that controls all cash register devices 11.

  Then, the bar storage control unit 60 switches the opening / closing from the opened state in which the bar tray 51 is pulled out to the housing 50 to the closed state in which the bar 50 is retracted, and the closed position switch after the drawer switch 59 is switched from OFF to ON. When it is detected by turning on 58, the amount of bar metal in the bar metal storage 14 is detected based on the presence / absence of bar metal detection based on the detection values of all the weight sensors 70a and the denomination identification result. That is, when the bar tray 51 is drawn out from the housing 50, the bar is taken out from the corresponding one of the plurality of set sections S for replenishment to the coin depositing and dispensing machine 31, or the set section S The bar metal B1, B5, B10, B50, B100, B500 of the bar metal tray 51 is additionally stored, such as any of the metal bars B1, B5, B10, B50, B100, B500, etc. Since there is a high possibility that the height will change, if the bar tray 51 is pulled out and stored in the housing 50, the present height is detected at this point. At this time, the set unit S that is in an abnormal state is excluded from detection of the height of the bar, and an abnormal signal is transmitted to the POS register control unit 20, and the POS register control unit 20 displays the signal. The part 24 displays that the abnormality has occurred in the bar storage 14 and the set part S in an abnormal state. The display of the set unit S in the abnormal state is, for example, displaying the entire layout and lighting the set unit S in the abnormal state. In addition, a lamp or the like may be attached to each set unit S so as to blink when there is an abnormality.

  Further, when the bar storage control unit 60 detects off-on switching from off to on of the external power supply via the POS register control unit 20, the bar metal storage control unit 60 detects the bar metal based on the detection values of all the weight sensors 70a. Based on the presence / absence and denomination identification result, the amount of bar metal in the bar metal storage 14 is detected. In other words, if an unstable power management situation occurs when the external power supply is turned off and the bar management is difficult, such as when a power failure occurs or a failure occurs, the bar is immediately restored when the power supply is restored. The amount of bar metal in the storage 14 is detected in the same manner as described above.

  Then, the bar metal storage control unit 60 transmits the detected amount of the bar metal to the POS cash register control unit 20, and the POS cash register control unit 20 stores the bar metal in the bar metal storage 14. The head amount is updated and stored, and the head amount is output to the system management device 71. Here, in the POS cash register control unit 20, for example, when there is an appropriate operation input to the operation unit 23, the amount of bar metal at that time is displayed on the display unit 24. Further, the system management device 71 calculates and displays the number and the like of the bar for each denomination to be prepared at the time of the next bar replenishment from the amount information of the bar sent to each register device 11. Based on this, the replenisher prepares the bar. Further, the system management device 71 monitors whether or not there is a denomination from which all the bar metal has been taken out for each cash register device 11, and there is a cashier device 11 having a replenishment denomination that has been taken out of all the bar metal. If this occurs, an alarm is generated to urge the cashier 11 to add a replenishment denomination required.

  According to the first embodiment described above, the bar tray 51 has a plurality of set portions S on which all types of bar bars B1, B5, B10, B50, B100, and B500 can be set. The set part S is provided with a weight sensor 70a capable of identifying the presence / absence of the bar and the denomination of the set bar, and the bar storage unit 60 controls the set part S corresponding to each weight sensor 70a. By detecting the presence or absence of a bar and the denomination of the set bar, the height of the bars B1, B5, B10, B50, B100, and B500 is detected. Thus, since the weight sensor 70a which detects the presence or absence of a bar metal and the denomination of the set bar metal is provided in all the setting parts S, it is possible to detect the height of the bar metal at an arbitrary timing. it can.

  Further, since the weight sensor 70a detects the presence or absence of a bar in the set unit S and the denomination of the set bar, no matter what type of bar is set in any set unit S, the height is incorrect. Set operation becomes easier.

  Furthermore, when opening / closing switching in which the bar tray 51 pulled out with respect to the housing 50 is accommodated is detected based on the detection results of the close position switch 58 and the drawer switch 59, the bar storage control unit 60 controls the amount of bar metal. Therefore, the amount of the metal bar can be automatically detected when the bar metal tray 51 is changed after being pulled out. That is, it is possible to efficiently detect the present height without unnecessarily performing the present height detection at a timing at which the present height does not change.

  In addition, when the bar storage control unit 60 detects the on / off switching from off to on of the external power supply, the bar metal storage controller 60 detects the amount of the metal bar, so that, for example, when the power supply is interrupted or a failure occurs, Even if it becomes difficult to manage the bar to be turned off, it is possible to detect the amount of the bar immediately after the power supply is restored. Therefore, even if a management problem occurs in a state where bar metal management is difficult, it is possible to respond immediately by detecting the height immediately.

  Furthermore, since the bar metal configured by packaging a specified number of loose coins has a weight difference that allows the denomination to be identified, the bar metal storage control unit 60 sets each bar in the set unit S. By comparing the weight of the bar metal detected by each weight sensor 70a with the reference weight of the bar metal of each denomination, the presence or absence of the bar metal in the set portion S and the denomination of the set bar metal are identified. . Therefore, it is possible to reliably detect the presence or absence of the bar and the denomination of the set bar with a simple configuration.

  Next, a bar storage room according to the second embodiment of the present invention will be described mainly with reference to FIG. 6 with a focus on differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the part similar to 1st Embodiment, and the description is abbreviate | omitted.

  The bar storage 14 of the second embodiment replaces the weight sensor 70a of the first embodiment with a distance sensor (bar) in order to identify the presence or absence of a bar in each set part S and the denomination of the set bar. (Money presence / absence / denomination identifying means) 70b is provided. FIG. 6 illustrates a state in which a 10-yen coin bar B10 is set.

  Therefore, first, all the set parts S of the bar metal tray 51 are configured such that the set height of the bar metal differs according to the outer diameter of the bar metal to be set. That is, each set portion S has a concave shape that is recessed downward with an isosceles trapezoidal shape in cross section, has a mirror symmetry with respect to the vertical plane, and a pair of support surfaces that are narrower toward each other. 75 and a horizontal bottom surface 76 connecting the lower edge portions of these support surfaces 75. Here, the shortest distance between the pair of support surfaces 75 is narrower than the outer diameter of the bar metal having the smallest outer diameter.

  As described above, the shortest distance from the bottom surface 76 of the bar metal, that is, the set height, of all the setting portions S differs depending on the outer diameter of the bar metal set to each of the set parts S. A non-contact distance sensor 70b for detecting the set height is provided on the bottom surface 76. The distance sensor 70b is, for example, an optical reflective sensor.

  The outputs of all the distance sensors 70b can be identified by scanning in a time division manner using a multiplexer circuit or the like, and transmitted to the bar storage controller 60. Here, all the set parts S are not set with the denominations of the metal bars B1, B5, B10, B50, B100, and B500 to be set. Since the set height detected by each distance sensor 70b provided in all the set parts S is good, the set height of the set metal bars B1, B5, B10, B50, B100, The presence / absence of a bar and the denomination of the set bar are identified based on whether there is a match within an allowable range with respect to each reference set height of B500.

  That is, if the set height within the predetermined value is not detected by the distance sensor 70b, it is determined that there is no bar, and if the set height within the predetermined value is detected by the distance sensor 70b, the detected set height is The standard set height of 1 yen bar B1, the standard set height of 5 yen bar B5, the standard set height of 10 yen bar B10, the standard set height of 50 yen bar B50, the 100 yen bar B100 Compared with the standard set height and the standard set height of 500 yen bar B500, if the error with the standard set height of any one denomination is within the allowable range, it is judged that there is a bar of that denomination. If the error is not in the allowable range with respect to the reference set height of any denomination, it is determined that there is an abnormal state (a set state of an object other than a bar or a set state of an abnormal bar).

  For example, if the set height detected by the distance sensor 70b is within the allowable range with respect to the reference set height of the 1-yen bar B1, it is determined that the 1-yen bar B1 is present, and the 5-yen bar B5 If the error with the reference set height is within the allowable range, it is determined that there is a 5-yen bar B5, and if the error with the reference set height of the 10-yen bar B10 is within the allowable range, there is a 10-yen bar B10. If the error with the reference set height of the 50 yen bar B50 is within the allowable range, it is determined that there is a 50 yen bar B50, and the error with the reference set height of the 100 yen bar B100 is within the allowable range. If it is, it is determined that there is a 100-yen bar B100, and if the error from the reference set height of the 500-yen bar B500 is within an allowable range, it is determined that there is a 500-yen bar B500. And the bar metal storage control part 60 detects the amount of bar metal in the bar metal storage 14 similarly to 1st Embodiment based on the detection result of all the distance sensors 70b. It should be noted that the allowable range of error of each reference set height is set so as not to overlap with the allowable range of errors of other reference set heights.

  According to the second embodiment described above, the metal bars B1, B5, B10, B50, B100, and B500 configured by wrapping loose coins having a specified outer diameter have an outer diameter that can identify the denomination. Because there is a difference, the set part S can use this outer diameter difference to change the set height, and all set parts S can identify the presence or absence of bar metal and the type of bar metal set. The distance sensor 70b is provided, and the bar storage controller 60 detects the presence or absence of the bar in the corresponding set unit S and the denomination of the set bar by each distance sensor 70b. The height of B1, B5, B10, B50, B100, and B500 is detected. Thus, since the distance sensor 70b which detects the presence or absence of a bar metal and the denomination of the set bar metal is provided in all the setting parts S, it is possible to detect the height of the bar metal at an arbitrary timing. it can.

  Moreover, since the distance sensor 70b detects the presence or absence of a bar in the set unit S and the denomination of the set bar, no matter what type of bar is set in any set unit S, the height is incorrect. Set operation becomes easier.

  Further, the set portion S is supported by a pair of support surfaces 75 having a shape in which the distance between each other is narrowed downward, so that the set height of the bars B1, B5, B10, B50, B100, and B500 is set for each outer diameter value. In order to make it different, the set height of the bar can be made different for each outer diameter value with a simple configuration.

  In addition, since the set height that changes in accordance with the outer diameter is detected by the distance sensor 70b, the setting gold having the same weight as the set denomination and different outer diameter cannot be detected in the first embodiment using the weight sensor. It can be determined that the bar other than the seed (including other objects) is not the bar of the set denomination.

  In addition, as shown in FIG. 7, the setting portion S is not a pair of support surfaces 75, but has the same height at an interval narrower than the outer diameter of the smallest diameter metal rod as seen from the axial direction of the metal rod to be set. A set of two support points 77 and a set of two support points 78 arranged at the same position and aligned in the axial direction, on both sides in the axial direction of the bar metal, You may make it vary the set height of this bar metal according to the outer diameter of the bar metal set by supporting at these support points. Even if comprised in this way, the set height of a bar metal can be varied for every outer diameter value with a simple structure.

  Next, the bar storage room according to the third embodiment of the present invention will be described mainly with reference to FIG. 8 focusing on the differences from the second embodiment. In addition, the same code | symbol is attached | subjected to the part similar to 2nd Embodiment, and the description is abbreviate | omitted.

  The bar metal storage 14 of the third embodiment replaces the distance sensor of the second embodiment with a magnetic sensor (bar metal) in order to identify the presence or absence of the bar metal in each set unit S and the denomination of the set bar metal. (Presence / absence / denomination identifying means) 70c is provided.

  That is, as in the second embodiment, the set portion S has a pair of support surfaces 75 whose intervals are narrowed downward, and a horizontal bottom surface 76 that connects the lower edges of the support surfaces 75. In addition, the distance from the bottom surface 76 of the bar metal, that is, the set height differs according to the outer diameter of the bar metal to be set, and the non-contact type magnetic sensor 70c for detecting the set height. Is provided on the bottom surface 76.

  The outputs of all the magnetic sensors 70c are scanned in a time-division manner by using a multiplexer circuit or the like and can be identified, and transmitted to the bar storage controller 60. Here, all the set parts S are not set with the denominations of the metal bars B1, B5, B10, B50, B100, and B500 to be set. For this reason, in the bar stock storage control unit 60, the magnetic data detected by the magnetic sensors 70c provided in all the set units S are the set denominations of the bar types B1, B5, B10, B50, B100, B500. The presence / absence of a bar and the denomination of the set bar are identified based on whether there is a match within the allowable range for each of the reference magnetic data.

  In other words, if the magnetic sensor 70c does not detect magnetic data at a level that can be determined that any of the metal bars B1, B5, B10, B50, B100, and B500 is present in the set portion S, the magnetic sensor 70c determines that there is no bar metal. When the sensor 70c detects the magnetic data at the above level, the detected magnetic data is converted into the reference magnetic data for the 1 yen bar B1, the reference magnetic data for the 5 bar B5, and the reference magnetic data for the 10 bar B10. Compared to the standard magnetic data of 50 yen bar B50, the standard magnetic data of 100 yen bar B100, and the standard magnetic data of 500 yen bar B500, the tolerance of any one type of magnetic data is acceptable If it is within the range, it is determined that there is a bar of that denomination. It judged to be in the set state) the state or the abnormal coin.

  For example, if the magnetic data detected by the magnetic sensor 70c is within an allowable range with respect to the reference magnetic data of the 1-yen bar B1, it is determined that the 1-yen bar B1 is present, and the 5-yen bar B5 is used as a reference. If the error with the magnetic data is within the allowable range, it is determined that there is a 5-yen bar B5. If the error with the reference magnetic data of the 10-yen bar B10 is within the allowable range, there is a 10-yen bar B10. If it is determined that the error from the reference magnetic data of the 50-yen bar B50 is within the allowable range, it is determined that the 50-yen bar B50 is present, and the error from the reference magnetic data of the 100-yen bar B100 is within the allowable range. If it exists, it is determined that there is a 100 yen bar B100, and if the error from the reference magnetic data of the 500 yen bar B500 is within an allowable range, it is determined that there is a 500 yen bar B500. And the bar metal storage control part 60 detects the amount of bar metal in the bar metal storage 14 similarly to 1st Embodiment based on the detection result of all the magnetic sensors 70c. Note that the allowable range of error of each reference magnetic data is set so as not to overlap with the allowable range of errors of other reference magnetic data.

  Here, in the magnetic sensor 70c, the detected magnetic data changes depending on the difference in the set height, but the detected magnetic data also changes depending on the difference in the material. Even if they are the same, if the material is different, the detected magnetic data will be different from the reference magnetic data. For this reason, by using the magnetic sensor 70c, the denomination identification can be determined by the set height and the material.

  According to the third embodiment described above, the metal bars B1, B5, B10, B50, B100, and B500 configured by wrapping loose coins having a specified outer diameter have an outer diameter that can identify the denomination. Since there is a difference, the set portion S uses this outer diameter difference to change the set height, and the magnetic data of the bar metal set in the set portion S is detected by the magnetic sensor 70c, which is set. The presence or absence of the set denomination bar is checked based on whether or not the denomination bar coincides with the reference magnetic data. Therefore, it is possible to reliably detect the presence or absence of the bar and the denomination of the set bar with a simple configuration.

  In addition, since the magnetic properties of the bar metal are detected by the magnetic sensor 70c, the bar metal having the same outer diameter and the same material as the bar metal of the handling denomination (others) cannot be detected in the second embodiment using the distance sensor 70b. (Including objects) can also be detected.

  Next, a bar storage room according to the fourth embodiment of the present invention will be described mainly with reference to FIG. 9 focusing on the differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the part similar to 1st Embodiment, and the description is abbreviate | omitted.

  In the fourth embodiment, each set portion S has a concave shape that is recessed downward, and is wider than the outer diameter of the set denomination bar so that the bar can be stored. It has a rectangular flat plate-like bottom surface 81 longer than the length of gold, a side surface 82 rising vertically from both long sides of the bottom surface 81, and an end surface 83 rising vertically from both short sides of the bottom surface 81. Also, on the one side in the axial direction, as viewed from the axial direction of the bar to be set, it is arranged at the same height position with a narrower interval than the outer diameter of the smallest diameter bar, and the position in the axial direction is aligned. Two support points 84 to be arranged are provided, and on the other side in the axial direction, an arcuate support portion 85 having a diameter larger than the outer diameter of all the denominations is provided. As a result, the set height of the bars B1, B5, B10, B50, B100, and B500 is constant regardless of the outer diameter at the position of one support portion 85, and is set according to the outer diameter at the position of the other support point 84. The height is different. Furthermore, a positioning portion 86 for determining the axial position of the bar is provided on the support portion 85 side. Of course, it is also possible to provide the positioning portion 86 on the support point 84 side.

  Here, all of the set portions S have a set denomination bar (for example, a 10-yen bar B10) set in advance as a denomination determination reference, with one end abutting against the positioning portion 86, and two locations. In a three-point support state in which one side in the axial direction is supported by the support point 84 and the other side in the axial direction is supported by the support portion 85, as shown by a solid line in FIG. The positional relationship among the positioning portion 86, the support portion 85, and the pair of support points 84 is set so that the center in the axial direction is located at the center with respect to the support point 84. As a result, when a coin having a diameter larger than that of the set denomination is set with one end abutting against the positioning portion 86, the support position side at the support point 84 is moved as shown by a two-dot chain line in FIG. When a coin having a diameter smaller than that of the set denomination bar is set with its one end abutting against the positioning portion 86, it is tilted so as to be positioned above the positioning portion 86 side. As shown, the support position side at the support point 84 is inclined so as to be located below the positioning portion 86 side.

  And in all the set parts S, with the space | interval in the axial direction of the bar metal to be set, the position of the support part 85 where the set height of the bar metal becomes constant regardless of the outer diameter, and the outer diameter Two magnetic sensors (bar metal presence / absence / denomination identifying means) 70d and 70e are provided at the positions of a pair of support points 84 having different bar metal set heights. The two sensors of the magnetic sensor 70d at the position of the support portion 85 and the magnetic sensor 70e at the position of the support point 84 are set when a predetermined set denomination bar (for example, a 10 yen bar B10) is set. It arrange | positions at the bottom face 81 so that the distance with a metal rod may become equal and an output may be balanced. The magnetic sensors 70d and 70e are, for example, those using eddy current type chip coils, and a sensor circuit (not shown) to which the magnetic sensors 70d and 70e are connected is connected to each of the magnetic sensors 70d and 70e. This is a differential circuit that uses a common balance coil, and is a circuit that scans the magnetic sensors 70d and 70e in a time-sharing manner.

  Since all the set parts S are not set with the denominations of the set metal bars B1, B5, B10, B50, B100, B500, any of the denominations may be set. The bar storage control unit 60 detects the presence or absence of bar metal based on the magnetic data detected by the magnetic sensors 70d and 70e provided in all the set units S, and checks the balance of these magnetic data, Based on whether the magnetic data is balanced or how much the unbalance amount is, the presence or absence of the bar and the denomination of the set bar are identified. That is, the balance of the magnetic data detected by the magnetic sensors 70d and 70e is confirmed, and the first predetermined range in which these unbalance amounts are set for a set denomination bar (for example, a 10-yen bar B10). If it is within and is balanced, it is determined that there is a set denomination (for example, a 10 yen bar B10), and if these unbalance amounts are within the second predetermined range, other than the set denomination If it is determined that there is a first denomination bar, and these unbalance amounts are within the third predetermined range, it is determined that there is a second denomination bar other than the set denomination, and these unbalances If the amount is in the fourth predetermined range, it is determined that there is a third denomination other than the set denomination, and if these unbalance amounts are in the fifth predetermined range, the third denomination other than the set denomination It is determined that there are four denominations, and these unbalance amounts are within the sixth predetermined range. For example, it is judged that there is a fifth denomination other than the set denomination, and if these unbalance amounts are not in any of the first to sixth ranges, an abnormal state (no bar, no bar Other object set state or abnormal bar metal set state).

  For example, when a bar having a larger outer diameter (for example, a 500-yen bar B500) than a set denomination (for example, a 10-yen bar B10) is set, the magnetic sensor 70d and the bar on the support unit 85 side Is a fixed distance, the distance between the magnetic sensor 70e on the support point 84 side and the bar is wider than the fixed distance, and the balance of the magnetic data of the magnetic sensors 70d and 70e is lost by an amount corresponding to the denomination. Therefore, even if a bar (for example, 1-yen bar B1) having an outer diameter smaller than that of the set denomination (for example, 10-yen bar B10) is set, the magnetic sensor 70d and the bar on the support unit 85 side are set. Whereas the distance from the gold is a fixed distance, the distance between the magnetic sensor 70e on the support point 84 side and the bar is closer than this fixed distance, and the balance of the magnetic data of the magnetic sensors 70d and 70e is an amount corresponding to the denomination. It will only collapse. Which bar is set is detected from an unbalance amount that differs depending on the denomination.

  And the bar metal storage control part 60 detects the amount of bar metal in the bar metal storage 14 based on the detection result of all the magnetic sensors 70d and 70e similarly to 1st Embodiment.

  According to the fourth embodiment described above, the metal bars B1, B5, B10, B50, B100, and B500 configured by wrapping loose coins having a specified outer diameter have an outer diameter that can identify the denomination. Since there is a difference, in the state where the set denomination bar is set in the set part S, the outputs of both magnetic sensors 70d and 70e are balanced, and a bar other than the set denomination is set. In this state, the balance between the outputs of the magnetic sensors 70d and 70e is lost in accordance with the outer diameter of the bar metal, and the bar metal storage control unit 60 determines the output of the two magnetic sensors 70d and 70e. The presence / absence of a bar and the denomination of the set bar are identified based on whether or not the output difference is balanced and the unbalance amount. Therefore, the presence / absence of a bar and the set denomination of the bar can be reliably identified with a simple configuration.

  In addition, since the balance between the outputs of the two magnetic sensors 70d and 70e occurs even when the diameter difference is small, it is possible to reliably detect the presence or absence of the set denomination. Further, since the external noise can be canceled by looking at the balance between the outputs of the two magnetic sensors 70d and 70e, the reliability is improved.
