The inclined guide wall surface 30a is erected on the right side in the width direction when viewed from the upstream side in the transport direction, and is inclined so as to approach the center in the width direction of the transport surface 14a toward the downstream side with respect to the extending direction of the transport surface 14a. doing. Thereby, the inclination guide wall surface 30a contacts the outer peripheral surface of the coin C which moves on the conveyance surface 14a, and guides this coin C to the width direction center side of the conveyance surface 14a. The inclined guide wall surface 30a matches the position of the conveying surface 14a in the extending direction with the upstream end of the wall surface 26a of the wall portion 26.

  When the reject wall 31 is horizontally rotatable and is in the standby state shown in FIG. 1, the standby guide wall surface (guide wall surface) 31 a on the conveyance surface 14 a side is continuous with the downstream end of the inclined guide wall surface 30 a of the wall portion 30. To do. When in the standby state, the standby guide wall surface 31a is erected on the right side in the width direction when viewed from the upstream side in the transport direction, and extends along the extending direction of the transport surface 14a. The standby guide wall surface 31a guides the coin C by contacting the outer peripheral surface of the coin C guided to the center side in the width direction of the transport surface 14a by the inclined guide wall surface 30a while moving on the transport surface 14a.

  The reference rail 32 has a reference guide wall surface (guide wall surface) 32a disposed on an extension of the standby guide wall surface 31a of the reject wall 31 in the standby state on the transport surface 14a side. The reference guide wall surface 32a is erected on the right side in the width direction when viewed from the upstream side in the transport direction, is provided on the downstream side of the inclined guide wall surface 30a, and extends along the extending direction of the transport surface 14a. The reference guide wall surface 32a guides the coin C by bringing the outer peripheral surface of the coin C moving on the transport surface 14a into contact with the standby guide wall surface 31a.

  An identification unit 35 for counting and counting coins C is embedded in the positions of the wall 25 and the wall 29 on the transport surface 14a. The identification unit 35 identifies whether or not the coin C is an acceptable coin C and the denomination of the acceptable coin C, and counts the acceptable coins C by denomination.

  The reject wall 31 constitutes a drop selection mechanism 37 together with a solenoid 36 that rotationally drives it, and is driven by the solenoid 36 to rotate between the above-described standby position and a reject position that is 90 degrees different from the standby position. . At the standby position, the reject wall 31 is connected to the standby guide wall surface 31a on the transport surface 14a side, which connects the downstream end of the inclined guide wall surface 30a of the wall portion 30 and the reference guide wall surface 32a of the reference rail 32, as described above. Position it on a flat surface. That is, when in the standby position, the reject wall portion 31 is in a non-projecting state in which it does not project from the downstream end of the inclined guide wall surface 30 a of the wall portion 30 and the reference guide wall surface 32 a of the reference rail 32. Further, when in the reject position, the reject wall portion 31 positions the other route change wall surface 31b on the transport surface 14a side, so that the route change wall surface 31b becomes the inclined guide wall surface 30a of the wall portion 30 and The projecting state projects from the reference guide wall surface 32a of the reference rail 32 to the center side in the width direction of the transport surface 14a.

  At the downstream position of the reject wall 31 on the transport surface 14a, a reject sorting hole (sorting hole) 38 for dropping the coin C identified as unacceptable by the identifying unit 35 is formed. The reject selection hole 38 is provided at a predetermined distance in the width direction of the transport surface 14a with respect to the standby guide wall surface 31a and the reference guide wall surface 32a at the standby position. Therefore, a drop regulating portion 39 is formed on the transport surface 14a between the reject selection hole 38 and the standby guide wall surface 31a and the reference guide wall surface 32a at the standby position.

  For the coin C identified as being acceptable by the identification unit 35, the drop selection mechanism 37 does not drive the solenoid 36 and puts the reject wall 31 in a non-projecting state located at the standby position. Then, the acceptable coin C moves on the drop restricting portion 39 of the transport surface 14a while the outer peripheral surface thereof is guided in contact with the standby guide wall surface 31a and the reference guide wall surface 32a arranged on the same plane. That is, the acceptable coin C comes into contact with the standby guide wall surface 31a and the reference guide wall surface 32a without being separated and is transported on the transport surface 14a, and falls without dropping from the reject sorting hole 38. It moves on the restricting portion 39, passes over the reject sorting hole 38, and moves to the downstream side of the reject sorting hole 38 on the transport surface 14a.

  On the other hand, for the coin C identified as unacceptable by the identification unit 35, the drop selection mechanism 37 drives the solenoid 36 to bring the reject wall 31 into a protruding state located at the reject position. Then, the unacceptable coin C is guided while its outer peripheral surface comes into contact with the course changing wall 31b of the reject wall 31. That is, the unacceptable coin C moves to the center side in the width direction of the transport surface 14a rather than the reference guide wall surface 32a by coming into contact with the course changing wall surface 31b, and is separated from the reference guide wall surface 32a by a predetermined amount. 14a is conveyed. As a result, the unacceptable coin C cannot move on the drop restricting portion 39 and falls from the transport surface 14a to the reject sorting hole 38. The coins C that have fallen from the reject sorting hole 38 are discharged to a reject port (not shown) through a chute (not shown). The reject sorting hole 38 does not drop the coins C that move on the drop restricting portion 39 for all denominations to be handled, and drops the coins C that are guided by contact with the path changing wall surface 31b. , Its size and shape are set.

  The coin C, which is identified as being acceptable by the identification unit 35 and guided on the outer peripheral surface by the standby guide wall surface 31a and the reference guide wall surface 32a arranged on the same plane, is located downstream of the reject sorting hole 38 on the transport surface 14a. Denomination selection holes 40 to 45 of denominations that are dropped from the transport surface 14a are formed. All of the denomination sorting holes 40 to 44 are provided at a predetermined distance from the reference guide wall surface 32a in the width direction of the transport surface 14a. The denomination sorting holes 40 to 45 are, in order from the upstream side, the narrowest width, the denomination sorting hole 40 for dropping only one-yen coin guided by the reference guide wall surface 32 a, and the width is wider than the denomination sorting hole 40. A denomination selection hole 41 for dropping only 50-yen coins guided by the guide wall surface 32a, and a denomination selection hole 42 for dropping only 5-yen coins that are wider than the denomination selection hole 41 and guided by the reference guide wall surface 32a. , A denomination selection hole 43 for dropping only a 100-yen coin guided by the reference guide wall surface 32a wider than the denomination selection hole 42, and a width wider than the denomination selection hole 43 and guided by the reference guide wall surface 32a. A denomination selection hole 44 for dropping only 10-yen coins and a denomination selection hole 45 for dropping only 500-yen coins that are widest and guided by the reference guide wall surface 32a.

  The transport belt mechanism 15 includes a pair of pulleys 47 and 48 disposed on the upstream side and the downstream side above the transport surface 14a, and an endless transport belt that transports the coin C by being wound around the pulleys 47 and 48. 49. The pulley 48 is a driving pulley that is connected to the motor 51 shown in FIG. 2 and applies a driving force to the conveyor belt 49, and the pulley 47 is a driven pulley that rotates with the conveyor belt 49. The pulley 48 is provided with a rotary encoder 52 shown in FIG.

  The upstream pulley 47 is provided immediately after the separation supply mechanism 12 and rotates about a central axis parallel to the transport surface 14a. The downstream pulley 48 is provided at the position of the most downstream denomination selecting hole 45 and rotates around a central axis parallel to the transport surface 14a. Although these pulleys 47 and 48 have their central axes parallel to each other, the downstream pulley 48 is located closer to the reference guide wall surface 32 a in the width direction of the transport surface 14 a than the upstream pulley 47.

  The conveyor belt 49 is a round belt having a circular cross section. When the conveyor belt 49 is wound around the pulleys 47 and 48, the lower side portion 50 positioned at the lower portion is closer to the reference guide wall surface toward the downstream side in the extending direction of the conveyor surface 14a. It inclines so that it may be located on the 32a side. The lower side portion 50 presses the coin C against the transport surface 14a and sandwiches the coin C between the transport surface 14a and transports it to the downstream side. At this time, the coin C is moved to the reference guide wall surface 32a by the above-described inclination. Transport while pressing.

  The transport belt mechanism 15 transports the coins C separated and sent one by one from the separation supply mechanism 12 to the downstream side while pressing the coin C against the transport surface 14 a by the lower side portion 50 of the transport belt 49. Then, after all the denominations of the coins C conveyed by the conveyor belt mechanism 15 are identified by the identification unit 35, the coin C comes into contact with the inclined guide wall surface 30a, and the width direction of the conveyor surface 14a is guided by the guidance. It moves downstream while gradually shifting its position to the center side. Thereafter, only the acceptable coin C moves downstream while being pressed against the standby guide wall surface 31a of the reject wall 31 and the reference guide wall surface 32a of the reference rail 32 by the lower side portion 50 of the conveyor belt 49, and the denomination It falls to the corresponding denomination of the sorting holes 40-45.

  In the present embodiment, as shown in FIG. 3, the inclined guide wall surface 30a, the standby guide wall surface 31a at the standby position, and the reference are located upstream of the reject sorting hole 38 of the transport surface 14a in the coin transport direction, that is, on the identification unit 35 side. Two upstream detection sensors 61 and 62 are provided with different distances in the width direction of the transport surface 14a with respect to the guide wall surface 32a. In addition, two downstream detection sensors are provided with different distances in the width direction of the conveying surface 14a with respect to the reference guide wall surface 32a on the downstream side of the reject sorting hole 38 of the conveying surface 14a in the coin conveying direction, that is, on the side opposite to the identification portion 35. 63, 64 are provided.

  Here, the upstream end of the reject sorting hole 38 has a shape that is inclined so as to be positioned upstream as the distance in the width direction of the transport surface 14a from the standby guide wall surface 31a at the standby position increases. . The upstream side detection sensors 61 and 62 are arranged in accordance with the shape of the upstream end of the reject sorting hole 38. That is, among the upstream side detection sensors 61 and 62, the upstream side detection sensor 61 having a short distance from the inclined guide wall surface 30a in the width direction of the transport surface 14a, the standby guide wall surface 31a at the standby position, and the reference guide wall surface 32a is the same. It is arranged on the downstream side in the transport direction with respect to the upstream side detection sensor 62 which is far away.

  If the coins C of all denominations to be handled are in contact with the inclined guide wall surface 30a during conveyance by the conveyance belt mechanism 15, the upstream side detection sensor 61 is affected by these coins C even if there is a hole. It is arranged at the position to detect everything. Specifically, the upstream side detection sensor 61 is disposed at a position to detect a portion between a hole of a 50-yen coin, which is a perforated coin in a state where the outer peripheral surface is in contact with the inclined guide wall surface 30a, and the inclined guide wall surface 30a. ing. That is, the 50-yen coin is a perforated coin and has a minimum radial width of the meat portion, and this radial width is shorter than the minimum diameter of the non-perforated coin. All denominations can be detected without being affected. The upstream side detection sensor 61 also serves as a timing sensor for measuring the drive timing of the solenoid 36 of the drop selection mechanism 37.

  The upstream side detection sensor 62 is configured such that when all the denomination coins C handled are separated from the inclined guide wall surface 30a during conveyance by the conveyance belt mechanism 15 and cannot be detected by the upstream side detection sensor 61. Even if there is a hole, it is arranged at a position where it is detected without being affected by it. Specifically, the upstream side detection sensor 61 is disposed at a position for detecting a portion between the hole of the 50-yen coin in a state where the outer peripheral surface is in contact with the wall surface 26a and the wall surface 26a.

  The downstream side detection sensors 63 and 64 are arranged with their positions in the transport direction aligned with each other. Among the downstream side detection sensors 63 and 64, the downstream side detection sensor 63, which is near the distance from the reference guide wall surface 32a in the width direction of the conveyance surface 14a, is carrying all the denominated coins C by the conveyance belt mechanism 15. If these are in contact with the reference guide wall surface 32a, these coins C are arranged at positions where they are all detected without being affected by the holes. Specifically, the downstream detection sensor 63 is arranged at a position for detecting a portion between the hole of the 50-yen coin in a state where the outer peripheral surface is in contact with the reference guide wall surface 32a and the reference guide wall surface 32a.

  Of the downstream detection sensors 63 and 64, the downstream detection sensor 64, which is far from the reference guide wall surface 32a in the width direction of the transport surface 14a, is transporting all the denominated coins C by the transport belt mechanism 15. The coin C is disposed at a position where all the coins C are detected without being influenced by the downstream detection sensor 63 when they are not in contact with the reference guide wall surface 32a and cannot be detected by the downstream detection sensor 63. Specifically, the downstream side detection sensor 64 is disposed at a position for detecting a portion between the hole of the 50-yen coin in a state where the outer peripheral surface is in contact with the wall surface 26a and the wall surface 26a.

  Therefore, the coins C of all the handling denominations are located on the upstream side of the reject sorting hole 38 during the transport by the transport belt mechanism 15 at any position in the width direction on the transport surface 14a. A portion other than the hole is detected by at least one of the detection sensors 61 and 62, and the portion other than the hole is detected by at least one of the two downstream detection sensors 63 and 64 on the downstream side of the reject selection hole 38. The part will be detected. In other words, the two upstream side detection sensors 61 and 62 can detect the coin C by at least one of the coins C of all handling denominations in any position in the width direction on the transport surface 14a. The two downstream detection sensors 63 and 64 are arranged so that the coins C of all handling denominations are located at any position in the width direction on the transport surface 14a. It is arranged at a position that can be detected by either of them.

  Moreover, the two upstream detection sensors 61 and 62 are configured to detect the coins C of all handling denominations if the coin C is detected by the upstream detection sensor 62 and not detected by the upstream detection sensor 61. It is disposed at a position where it may not be possible to return to the position where it is placed on the drop restricting portion 39 even by the inclined conveyance by the lower side portion 50 of the conveyance belt 49 of the conveyance belt mechanism 15.

  As shown in FIG. 2, the separation supply mechanism 12, the transport belt mechanism 15, the identification unit 35, the drop selection mechanism 37, the upstream side detection sensors 61 and 62, and the downstream side detection sensors 63 and 64 include a control unit (determination unit). ) 70 is communicably connected.

  And the control part 70 is the detection timing with a coin by at least any one of the two upstream detection sensors 61 and 62, the elapsed time from this detection timing, and the two downstream detection sensors 63 and 64. Based on whether or not the coin C is detected by any one of the above, whether or not the coin C is dropped in the reject sorting hole 38 is determined. The elapsed time can be actually measured by a timer or by counting the number of pulses of the rotary encoder 52 of the conveyor belt mechanism 15 that rotates at a constant speed.

  The control unit 70 sets the elapsed time from the detection timing of the coin C to be judged by the upstream detection sensor 61 on the side closer to the inclined guide wall surface 30a out of the two upstream detection sensors 61 and 62 to a predetermined reference range. When the presence of a coin is detected by one of the two downstream detection sensors 63 and 64 at a certain timing, it is determined that the determination target coin C does not fall through the reject sorting hole 38.

  That is, when the upstream detection sensor 62 located further upstream of the two upstream detection sensors 61 and 62 detects the coin C, the control unit 70 counts the coin C as the current determination target coin C. Start (at the start of the first timing). Next, before the elapsed time from the start timing of the first time reaches the predetermined separation determination reference time, the upstream detection sensor 61 located on the downstream side of the two upstream detection sensors 61 and 62 has the coin C Is detected, the coin C is determined to be the current determination target coin C, the time measurement is reset, and the time measurement is started again from 0 (second time measurement start time). At the same time, based on the identification result by the identification unit 35, when the determination target coin C is a reject coin, the solenoid 36 of the drop selection mechanism 37 is driven for a predetermined time to rotate the reject wall 31 for a predetermined time. If it is a coin, the solenoid 36 of the drop selection mechanism 37 is not driven and the reject wall 31 is not rotated. If the diameter of the coin C is small, the upstream detection sensor 61 may detect the coin C without the upstream detection sensor 62 being detected by the coin C. In this case, the upstream detection sensor 61 may detect the coin C. Is detected, this time is the second time start point.

  When the reject wall portion 31 is rotated to the reject position, when one of the two downstream detection sensors 63 and 64 detects the coin C, the process from the start of the second timing until this point is reached. If the time is within the predetermined first passage determination reference range, it is determined that the coin C is the current determination target coin C, and the current determination target coin C does not fall in the reject sorting hole 38, It is determined that it has passed over the reject sorting hole 38. As a result, the control unit 70 determines that a reject sorting abnormality has occurred in which the coin C to be dropped in the reject sorting hole 38 does not fall in the reject sorting hole 38 and passes over the reject sorting hole 38.

  On the other hand, when the control unit 70 does not rotate the reject wall 31 from the standby position, when one of the two downstream detection sensors 63 and 64 detects the coin C, the time until this point is reached. If the elapsed time from the second timing start time is within the predetermined second passage determination reference range, it is determined that this coin C is the current determination target coin C, and the current determination target coin C is rejected. It is determined that it has not passed through the sorting hole 38 and has passed over the reject sorting hole 38. Thereby, the control unit 70 determines that the coin C that should not fall in the reject sorting hole 38 has normally passed over the reject sorting hole 38.

  The controller 70 determines that the elapsed time from the detection timing of the coin C to be determined by the upstream detection sensor 61 on the inclined guide wall surface 30a side of the two upstream detection sensors 61 and 62 exceeds a predetermined reference time. On the other hand, if the presence of coins is not detected by any of the two downstream detection sensors 63 and 64, it is determined that the determination target coin C has fallen in the reject sorting hole 38.

  In other words, when the upstream side detection sensor 62 detects the coin C, the control unit 70 starts measuring time with the coin C as the current determination target coin C (first timing start time). Next, if the upstream side detection sensor 61 detects the coin C before the elapsed time from the start timing of the first time reaches the predetermined separation determination reference time, the coin C is determined to be the current determination target coin C. Judgment is made to reset the timekeeping time, and timekeeping starts again from 0 (second timekeeping start time). At the same time, based on the identification result by the identification unit 35, when the determination target coin C is a reject coin, the solenoid 36 of the drop selection mechanism 37 is driven for a predetermined time to rotate the reject wall 31 for a predetermined time. If it is a coin, the solenoid 36 of the drop selection mechanism 37 is not driven and the reject wall 31 is not rotated. When the diameter of the coin C is small, the upstream detection sensor 61 may detect the coin C without the upstream detection sensor 62 detecting the coin C. In this case, the upstream detection sensor 61 may detect the coin C. Is detected, this time is the second time start point.

  When the reject wall 31 is rotated to the reject position, the two downstream detection sensors 63 and 64 do not detect the coin C, and the predetermined time which is the longest time of the first passage determination reference range described above. When the first passage determination maximum reference time has passed, it is determined that the current determination target coin C has fallen in the reject sorting hole 38. As a result, the control unit 70 determines that the coin C that should fall into the reject sorting hole 38 has fallen normally into the reject sorting hole 38.

  On the other hand, if the control unit 70 does not rotate the reject wall 31 from the standby position, then the second passage determination criterion described above without any of the two downstream detection sensors 63 and 64 detecting the coin C. When the predetermined second passage determination maximum reference time, which is the longest time of the range, has passed, it is determined that the current determination target coin C has fallen in the reject sorting hole 38. As a result, the control unit 70 determines that a reject sorting abnormality has occurred in which the coin C that should not fall into the reject sorting hole 38 has fallen into the reject sorting hole 38.

  When the control unit 70 detects that there is a coin of the determination target coin C only by the upstream detection sensor 62 on the side opposite to the inclined guide wall surface 30a among the two upstream detection sensors 61 and 62, the progress from the timing of the detection. When the presence of a coin is detected by one of the two downstream detection sensors 63 and 64 at a timing when the time is within a predetermined reference range, it is determined that the determination target coin C does not fall through the reject sorting hole 38.

  In other words, when the upstream side detection sensor 62 detects the coin C, the control unit 70 starts measuring time with the coin C as the current determination target coin C (first timing start time). Next, in a state in which the upstream detection sensor 61 does not detect the coin C, after the elapsed time from the first timing start time has passed a predetermined separation determination reference time, one of the two downstream detection sensors 63 and 64 When the earlier one detects the coin C, if the elapsed time from the first timing start time up to this point is within a predetermined third passage determination reference range, this coin C is the current determination target coin C. It is determined that the current coin C to be determined has not passed through the reject sorting hole 38 and has passed over the reject sorting hole 38. That is, from the identification result of the identification unit 35, the control unit 70 determines that the current determination target coin C has passed normally over the reject selection hole 38 when it is not the coin C to be dropped into the rejection selection hole 38. On the other hand, from the identification result of the identification unit 35, when the current coin C to be judged is the coin C that should fall into the reject sorting hole 38, the coin C that should fall into the reject sorting hole 38 has passed over the reject sorting hole 38. It is determined that a reject sorting error has occurred.

  In addition, although it is a reference technique, the presence of a coin of the judgment target coin C is detected only by the upstream detection sensor 62 on the opposite side to the inclined guide wall surface 30a among the two upstream detection sensors 61 and 62 (that is, the coin C is detected). When it is determined that the separation guide wall surface 32a is away from the reference guide wall surface 32a), the separation supply mechanism 12 and the conveyance belt mechanism 15 may be stopped to generate an alarm. Specifically, when the above-described upstream side detection sensor 62 detects the coin C and the upstream side detection sensor 61 does not detect the coin C, the separation supply mechanism 12 is passed when a predetermined separation determination reference time has passed. Then, the conveying belt mechanism 15 is stopped and an alarm is generated. Similarly, when the existence of coins of the judgment target coin C is detected only by the downstream detection sensor 64 on the side opposite to the reference guide wall surface 32a among the two downstream detection sensors 63 and 64, the separation supply mechanism 12 and the transport belt mechanism 15 are detected. May be stopped to generate an alarm.

  When the control unit 70 detects that there is a coin of the determination target coin C only by the upstream detection sensor 62 on the side opposite to the inclined guide wall surface 30a among the two upstream detection sensors 61 and 62, the progress from the timing of the detection. If the presence of coins is not detected by any of the two downstream detection sensors 63 and 64 even after the predetermined reference time has elapsed, it is determined that the determination target coin C has fallen through the reject sorting hole 38.

  In other words, when the upstream side detection sensor 62 detects the coin C, the control unit 70 starts measuring time with the coin C as the current determination target coin C (first timing start time). Next, in a state in which the upstream detection sensor 61 does not detect the coin C, after the elapsed time from the first timing start time has passed a predetermined separation determination reference time, one of the two downstream detection sensors 63 and 64 In any case, if the elapsed time from the start of the first timing exceeds the predetermined third passage determination maximum reference time which is the longest time of the third passage determination reference range without detecting the coin C, the current determination target coin It is determined that C has dropped at the reject sorting hole 38. That is, from the identification result of the identification unit 35, the control unit 70 determines that the current determination target coin C is normally dropped from the reject sorting hole 38 when it is the coin C that should fall into the reject sorting hole 38. On the other hand, if the coin C to be judged is not the coin C that should be dropped into the reject sorting hole 38 based on the discrimination result of the discriminating unit 35, the reject that the coin C that should not fall into the reject sorting hole 38 has fallen into the reject sorting hole 38 is rejected. It is determined that a sorting abnormality has occurred.

  The control unit 70 accepts the coin C that is identified as being unacceptable and should fall from the reject sorting hole 38 based on the identification result of the identifying unit 35, or is not acceptable or accepts the coin C that should pass through the reject sorting hole 38. The following control is performed at the time of the close conveyance in which the coin C identified to fall from the reject selection hole 38 is continuously conveyed at a narrow interval.

  The control unit 70 falls after the detection of the presence of the coin of the preceding coin C to be dropped from the reject sorting hole 38 by the upstream detection sensor 61 on the inclined guide wall surface 30a side of the two upstream detection sensors 61 and 62. In the case where the succeeding coin C following the preceding preceding coin C is the coin C to be dropped from the reject sorting hole 38, from the detection timing (the second timing start time) of the succeeding coin C by the upstream detection sensor 61. Is present at a timing earlier than a predetermined first passage determination minimum reference time which is the shortest time of the first passage determination reference range, and there is a coin by one of the two downstream detection sensors 63 and 64 which is earlier. Is detected (that is, when early arrival of the coin C is detected), it is determined that the coin C to be dropped does not fall through the reject sorting hole 38.

  Further, the control unit 70 detects the presence of the coin of the preceding coin C to be dropped from the reject sorting hole 38 by the upstream detection sensor 61 on the inclined guide wall surface 30a side of the two upstream detection sensors 61 and 62, When the succeeding coin C following the preceding coin C to be dropped is a coin C that should not be dropped in the reject sorting hole 38, the detection timing (second timing) of the succeeding coin C by the upstream detection sensor 61 The elapsed time from the start time) is earlier than a predetermined second passage determination shortest reference time that is the shortest time in the second passage determination reference range, whichever of the two downstream detection sensors 63 and 64 is earlier. When the presence of a coin is detected by one side (that is, when early arrival of the coin C is detected), it is determined that the coin C to be dropped does not fall through the reject sorting hole 38.

  That is, for example, when the conveyance interval of the coins C becomes narrow and it is difficult to determine whether the detection by the upstream detection sensor 61 and the detection by the downstream detection sensors 63 and 64 are the same coin C or not. When an abnormality occurs in which the preceding coin C to be dropped from the reject sorting hole 38 does not fall, the preceding coin C is detected at two timings earlier than the timing at which the succeeding coin C is to be detected. By utilizing the fact that one of 63 and 64 is detected, a reject sorting abnormality in which the preceding coin C to be dropped in the reject sorting hole 38 has passed over the reject sorting hole 38 is detected.

  In the above description, the control unit 70 should accept and pass the reject sorting hole 38 with respect to the coin C identified from the discrimination result of the discrimination unit 35 as being acceptable and passing through the reject sorting hole 38. You may make it perform the following control at the time of the proximity | contact conveyance in which the coin C is continuously conveyed by the narrow space | interval.

  The control unit 70 detects the presence of coins of the preceding coin C to be passed over the reject sorting hole 38 by the upstream detection sensor 61 on the reference guide wall surface 32a side of the two upstream detection sensors 61 and 62 (second timing). The elapsed time from the time measurement start point) exceeds a predetermined second passage determination longest reference time that is the longest time of the second passage determination reference range, whichever of the two downstream detection sensors 63 and 64 is earlier. When the presence of a coin is detected by one side (that is, when the late arrival of the coin C is detected), it is determined that the preceding coin C that should pass through the reject sorting hole 38 has fallen into the reject sorting hole 38. Also good.

  That is, when an anomaly occurs in which the preceding coin C that should pass through the reject sorting hole 38 falls into the reject sorting hole 38, the succeeding coin C that should pass through the reject sorting hole 38 is a reference for the preceding coin C. By utilizing the fact that one of the two downstream detection sensors 63 and 64 is detected after a lapse of time, a reject sorting abnormality in which the preceding coin C that should pass through the reject sorting hole 38 has fallen from the reject sorting hole 38 is detected. To do.

  If the control unit 70 determines that the coin C determined to be acceptable from the identification result of the identification unit 35 does not fall in the reject sorting hole 38 and has passed over the reject sorting hole 38, the reject sorting is normal. Judge that there was.

  In addition, when the control unit 70 determines that the coin C determined to be acceptable from the identification result of the identification unit 35 has dropped from the reject selection hole 38, the control unit 70 determines that the rejection selection is abnormal, and the identification unit 35 Are subtracted from the number of acceptable coins C calculated from the identification result, and an error is notified.

  In addition, when it is determined that the coin C determined to be unacceptable from the identification result of the identification unit 35 has fallen from the reject sorting hole 38, the control unit 70 determines that the reject sorting is normal.

  In addition, when the control unit 70 determines that the coin C determined to be unacceptable from the identification result of the identification unit 35 does not fall in the reject selection hole 38 and passes over the reject selection hole 38, the reject selection is performed. It is determined that there is an abnormality, the separation supply mechanism 12 and the conveyor belt mechanism 15 are immediately stopped, an error is notified, and the manual removal of the coin C on the conveyor surface 14a is urged.

  The control unit 70 also determines that there is a coin if the continuous detection time with coins is equal to or longer than a predetermined detection judgment reference time for each of the two upstream detection sensors 61 and 62 and the two downstream detection sensors 63 and 64. If it is shorter than the predetermined detection determination reference time, it is determined that the coin is not detected. Here, when the continuous detection time with coins is shorter than a predetermined detection determination reference time, the control unit 70 determines that a foreign object has been detected, and immediately stops the separation supply mechanism 12 and the conveyance belt mechanism 15. Thus, an error is notified and the manual removal of the foreign matter on the transport surface 14a is urged.

  According to the present embodiment described above, the two upstream side detection sensors 61 and 62 are arranged on the upstream side of the reject selection hole 38 with different distances from the inclined guide wall surface 30a, the standby guide wall surface 31a and the reference guide wall surface 32a. And two downstream detection sensors 63 and 64 are provided on the downstream side of the reject selection hole 38 at different distances from the reference guide wall surface 32a, and the control unit 70 includes two upstream detection sensors 61 and 62. Based on the detection timing of the presence of coins by at least one of them, the elapsed time from this detection timing, and the presence or absence of detection of coins by one of the two downstream detection sensors 63, 64 Whether or not the coin C is dropped in the sorting hole 38 is determined. As a result, it is possible to determine whether or not there is a drop in the reject sorting hole 38 for both the coin C in contact with the reference guide wall surface 32a and the coin C in a state separated from the reference guide wall surface 32a. Therefore, it is possible to improve the reliability related to sorting.

  Further, the two upstream side detection sensors 61 and 62 on the upstream side of the reject sorting hole 38 can detect the coin C regardless of the position in the width direction on the transport surface 14a. The two downstream detection sensors 63 and 64 on the downstream side of the reject sorting hole 38 are detected by at least one of them, and the positions of the coins C of all handling denominations in the width direction on the transport surface 14a. Even if it exists, the said coin C will be detected by at least any one. As a result, it is possible to determine whether or not the coins C of all handling denominations transported on the transport surface 14a have fallen in the reject sorting hole 38. Therefore, it is possible to improve the reliability related to sorting.

  In addition, the control unit 70 recognizes the coin of the determination target coin C only by the upstream detection sensor 62 on the opposite side of the two upstream detection sensors 61 and 62 from the inclined guide wall surface 30a, the standby guide wall surface 31a, and the reference guide wall surface 32a. When the presence is detected, if the presence of a coin is detected by one of the two downstream detection sensors 63 and 64 at a timing when the elapsed time from the detection timing is within a predetermined reference range, the reject selection of the determination target coin C is rejected. It is determined that there is no drop in the hole 38. Thereby, it is possible to determine whether or not the coin C is separated from the inclined guide wall surface 30a on the upstream side of the reject sorting hole 38 and does not fall from the reject sorting hole 38.

  In addition, the control unit 70 recognizes the coin of the determination target coin C only by the upstream detection sensor 62 on the opposite side of the two upstream detection sensors 61 and 62 from the inclined guide wall surface 30a, the standby guide wall surface 31a, and the reference guide wall surface 32a. When the presence is detected, if the presence of coins is not detected by any of the two downstream detection sensors 63 and 64 even if the elapsed time from the detection timing exceeds a predetermined reference time, the reject selection of the judgment target coin C is rejected. It is determined that there is a drop in the hole 38. As a result, it is possible to determine whether or not a coin that is separated from the inclined guide wall surface 30a on the upstream side of the reject sorting hole 38 and falls from the reject sorting hole 38 is dropped.

  Further, the control unit 70 detects the presence of the coin of the judgment target coin C by the upstream detection sensor 61 on the inclined guide wall surface 30a, the standby guide wall surface 31a, and the reference guide wall surface 32a of the two upstream detection sensors 61 and 62. If the presence of a coin is detected by one of the two downstream detection sensors 63 and 64 at a timing when the elapsed time from the timing is within a predetermined reference range, it is determined that the determination target coin C does not fall through the reject sorting hole 38. To do. Thereby, about the coin C which maintains the state which contacts the reference | standard guide wall surface 32a before and behind the rejection selection hole 38, and the coin C which will be in the state away from the reference | standard guide wall surface 32a from the state which contacts the reference | standard guide wall surface 32a, It can be determined that there is no drop in the reject sorting hole 38.

  Further, the control unit 70 detects the presence of the coin of the judgment target coin C by the upstream detection sensor 61 on the inclined guide wall surface 30a, the standby guide wall surface 31a, and the reference guide wall surface 32a of the two upstream detection sensors 61 and 62. Even if the elapsed time from the timing exceeds a predetermined reference time, if the presence of coins is not detected by any of the two downstream detection sensors 63 and 64, it is determined that the determination target coin C has fallen in the reject sorting hole 38. To do. Thereby, about the coin C which maintains the state which contacts the reference | standard guide wall surface 32a before and behind the rejection selection hole 38, and the coin C which will be in the state away from the reference | standard guide wall surface 32a from the state which contacts the reference | standard guide wall surface 32a, It can be determined that there is a drop in the reject sorting hole 38.

  Further, the control unit 70 should be dropped from the reject selection hole 38 by the upstream detection sensor 61 on the inclined guide wall surface 30a, the standby guide wall surface 31a and the reference guide wall surface 32a side of the two upstream detection sensors 61 and 62. After detection of the presence of coins in coin C, the elapsed time from the detection timing of presence of coins by upstream detection sensor 61 on the reference guide wall surface 32a side of subsequent coins C following the preceding coins C to be dropped is a predetermined reference time. If the presence of a coin is detected by at least one of the two downstream detection sensors 63 and 64 at an earlier timing, it is determined that the preceding coin C to be dropped does not fall in the reject sorting hole 38. As a result, it is possible to determine whether there is no abnormality in the reject sorting hole 38 of the preceding coin C that should fall from the reject sorting hole 38.

  Further, the control unit 70 should pass over the reject selection hole 38 by the upstream detection sensor 61 on the inclined guide wall surface 30a, the standby guide wall surface 31a, and the reference guide wall surface 32a side of the two upstream detection sensors 61 and 62. When the elapsed time from the detection timing of the preceding coin C with the presence of a coin passes a predetermined reference time and one of the two downstream detection sensors 63 and 64 detects the presence of a coin, it should pass over the reject sorting hole 38. It is determined that the preceding coin C has fallen in the reject sorting hole 38. As a result, it is possible to determine whether there is a drop in the reject sorting hole 38 of the preceding coin C that should pass through the reject sorting hole 38.

  Further, the control unit 70 detects the presence of coins when the continuous detection time with coins is shorter than a predetermined reference time for each of the two upstream detection sensors 61 and 62 and the two downstream detection sensors 63 and 64. Therefore, it is possible to suppress erroneous detection due to foreign matter or the like.

  In the above description, the case where the sorting hole is the reject sorting hole 38 for returning the unacceptable coin C has been described as an example. However, the gold for sorting the acceptable coins C of specific denominations from the coins of other denominations. The present invention can also be applied to a seed selection hole.
