In the following description, “front” is the operator side, “rear” is the opposite side of the operator, and “left and right” are left and right as viewed from the operator.

  1 and 2 show a paper sheet counter 1 of the present embodiment. 1 and 2, reference numeral 11 denotes a hopper on which a plurality of paper sheets S are stacked in the vertical direction with the length direction set in the horizontal direction. The sheets S put in the hopper 11 in a stacked state are sequentially kicked out backward from the bottom one by the kicking roller 12 and supplied between the feeding roller 13 and the separation roller 14. The feeding roller 13 is driven by the counting motor 15 shown in FIG. 1 and rotates clockwise in FIG. Between the counting motor 15 and the feeding roller 13, there are provided a clutch 16 shown in FIG. 3 that switches between transmission and interruption of rotation and a brake 17 that suddenly stops the feeding roller 13. As shown in FIG. 1, the hopper 11 is provided with a reflective insertion detection sensor 18 that detects the presence or absence of a paper sheet S on the hopper 11.

  The kicking roller 12 is connected to the feeding roller 13 and rotates in the clockwise direction in FIG. 1 in conjunction with the feeding roller 13 by the driving force of the counting motor 15. A friction member 12 a is partially provided on the outer peripheral portion of the kicking roller 12, and a friction member 13 a is partially provided on the outer peripheral portion of the feeding roller 13. The kick roller 12 kicks out the paper sheet S when the friction member 12a comes into contact with the paper sheet S. The feeding roller 13 moves the paper sheet S between the separation roller 14 and the friction member 13a in contact with the paper sheet S. Pull in and feed backwards. The separation roller 14 is stopped and stops the paper sheet S above the paper sheet S that contacts the feeding roller 13.

  A kick roller 12, a feeding roller 13, a separation roller 14, a counting motor 15, a clutch 16 and a brake 17 sequentially separate the sheets S loaded in a stacked state in the hopper 11 one by one from the bottom one by one. Thus, a feeding portion 21 that extends backward is configured.

  The feeding unit 21 feeds the paper sheet S to the transport unit 22 (transport unit). The conveyance unit 22 includes a conveyance path 23 that guides the backward and downward movement of the paper sheet S fed from the feeding unit 21 and the forward movement of the folded sheet S, and a plurality of conveyance rollers 24 arranged at various points in the conveyance path 23. And have. These transport rollers 24 are rotationally driven by the counting motor 15 described above, and therefore the counting motor 15 is shared by the feeding unit 21 and the transport unit 22. The transport unit 22 transports the paper sheet S with the transport rollers 24 or between the transport roller 24 and other components.

  Further, the transport unit 22 is provided with a pair of integrated discharge vehicles 25 and a guide unit 26 shown in FIG. Further, the transport unit 22 includes an integrated discharge vehicle motor 27 shown in FIG. 3 that rotationally drives the pair of integrated discharge vehicles 25. The stacking discharge wheel 25 is driven to rotate counterclockwise in FIG. 1, and discharges the sequentially inserted sheets S toward the stacking unit 30 (stacking means). The accumulating portion 30 has a bottom portion 31 having a top surface inclined slightly forward and downward at an angle close to horizontal, and a receiving wall 32 having a rear surface rising slightly upward and inclined from the front end portion of the bottom portion 31 at an angle close to vertical. have. The receiving wall 32 rises from the front end portion of the bottom portion 31 and forms the lower front surface of the paper sheet counter 1.

  The integrated discharge wheel 25 has a large number of blades 33 extending rearward on the upstream side in the rotation direction when positioned at the upper portion thereof, and the paper sheet S fed from the upstream conveying roller 24 is removed. During rotation, it is received in the gap between the upper adjacent blades 33 facing the conveying roller 24 at that time. The integrated discharge wheel 25 rotates to convey the paper sheet S sandwiched between the blades 33 forward and downward.

  As shown in FIG. 2, the pair of integrated discharge vehicles 25 are provided at intervals in the left-right direction, and these integrated discharge vehicles 25 are provided so that only the upper portion and the front portion protrude from the guide portion 26. ing. As shown in FIG. 1, the guide unit 26 includes an upper guide 35 that extends rearward from the integrated discharge wheel 25 and restricts the downward movement of the paper sheet S fed from the transport roller 24, and a front end of the upper guide 35. It has a front guide portion 36 that is curved from the edge portion and extends forward and downward and is connected to the bottom portion 31 of the stacking portion 30.

  The sheet S fed out from the conveying roller 24 and inserted between the blades 33 of the stacking discharge wheel 25 is sandwiched between the adjacent blades 33 and moved forward and downward by rotating the stacking discharge wheel 25 and guiding the guide unit 26. While being conveyed, in the meantime, it abuts against the upper surface of the bottom 31 of the stacking unit 30 in a standing state. Then, the paper sheet S is further prevented from descending, and is pulled out from between adjacent blades 33 of the rotating stacking discharge wheel 25 (that is, discharged from the transport unit 22 to the stacking unit 30) and held until then. The blade 33 is pushed forward by the blade 33 on the upstream side in the rotation direction. As a result, the sheet S is moved forward while the lower end edge is guided on the upper surface of the bottom 31 of the stacking unit 30 while being in the standing position, and is received by the receiving wall 32 of the stacking unit 30. Therefore, the stacking unit 30 receives the paper sheets S discharged from the transport unit 22 by the front receiving wall 32 and stacks them in the front-rear direction in the standing state. The stacking unit 30 is provided at a position exposed to the outside of the apparatus, and thus allows the stacked paper sheets S to be taken out of the apparatus.

The thickness detection unit 51 detects the position of the bearing 52 by detecting the position of the bearing 52 and the bearing 52 provided so as to be able to approach and move away from each other in the radial direction with respect to the one conveyance roller 24 whose position in the conveyance direction of the sheet S is matched. A detection main body 53 shown in FIG. 3 for detecting the thickness of the leaf S is provided. As shown in FIG. 1, the bearing 52 of the thickness detection unit 51 is provided on the downstream side of the identification counting unit 41 in the transport direction of the paper sheet S.

  At the folded portion of the transport unit 22, a transport residual detection sensor 61 that detects the paper sheet S moving through the transport unit 22 is provided. The conveyance residual detection sensor 61 is an optical sensor composed of a light emitting element 61a and a light receiving element 61b. Similar to the counting sensor 42, a paper sheet S between these elements depends on whether the light receiving element 61b receives light from the light emitting element 61a. Detects the absence of. The conveyance residual detection sensor 61 is provided on the downstream side of the bearing 52 of the thickness detection unit 51 in the conveyance direction of the paper sheet S.

  The stacking unit 30 is provided at a front position facing the outside of the sheet counting machine 1, and the upper front side thereof is open. Therefore, the paper sheet S discharged to the stacking unit 30 by the transport unit 22 is exposed to the outside of the apparatus and can be visually observed by the operator. That is, the stacking unit 30 receives and stacks the paper sheets S discharged from the transport unit 22 so as to be visible.

  The front guide part 36 and the receiving wall 32 of the guide part 26 are provided with a discharge residual detection sensor 65 (presence / absence detection means) that detects the presence or absence of the paper sheet S on the upper surface of the bottom part 31 of the stacking part 30. . The discharge residual detection sensor 65 is an optical sensor including a light emitting element 65a provided on the front guide portion 36 and a light receiving element 65b provided on the receiving wall 32, and the light emitted from the light emitting element 65a is received by the light receiving element. In a state where light is received by 65b, it is detected that there is no paper sheet S between them, that is, in the stacking unit 30, and in a state where the light receiving element 65b does not receive the light emitted by the light emitting element 65a, between these, that is, in the stacking unit 30 The presence of the paper sheet S is detected.

  As shown in FIG. 2, the stacking unit 30 is configured such that the center portion in the left-right direction of the bottom portion 31 is an insole forming portion 71 integrated with the guide portion 26. The stacking unit 30 has a slide member 72 that can slide in the front-rear direction with respect to the insole component 71. When the portion excluding the slide member 72 of the paper sheet counting machine 1 is the counting machine main body 101, the insole forming portion 71 is provided in the counting machine main body 101. The counter body 101 is formed with side wall portions 102 projecting forward from the guide portion 26 on both the left and right sides of the guide portion 26. The side wall portions 102 on both sides are formed with a protruding portion 104 protruding forward from the intermediate portion 103 in the vertical direction at the upper portion, and an extending portion 105 extending forward from the intermediate portion 103 and the protruding portion 104 at the lower portion. Is formed. A slide member 72 is disposed between the extending portions 105 on both sides.

  As shown in FIG. 4, the slide member 72 includes left and right side bottom components 75 that constitute the bottom 31 on both sides of the midsole component 71, and both side bottom components 75 that are located below the midsole component 71. The connecting portion 76 that connects the two, the receiving wall 32 that extends upward from the front edge of the side bottom component 75 on both sides, and the middle bottom component 71 of each of the side bottom components 75 on opposite sides are opposite to each other. It has integrally the wall part 77 of the both sides extended upwards from the edge part of the side. A pair of left and right guide grooves 81 are formed in the connecting portion 76, and the slide member 72 is formed by a pair of left and right guide pins 82 that are inserted into the guide grooves 81 and fixed to the midsole component 71. 71 is connected. As shown in FIG. 5, the guide groove 81 has a long shape in the front-rear direction, and the guide pin 82 can move relative to the guide groove 81 in the front-rear direction. As a result, the slide member 72 is slidably connected to the midsole component 71 of the counter body 101.

  The slide member 72 is determined by the guide groove 81 as shown in FIGS. 5A and 5B while maintaining the upper surfaces of the side bottom component portions 75 on both sides in the same plane as the upper surface of the midsole component portion 71. It can slide back and forth within a predetermined range. That is, as shown in FIG. 5A, the guide pin 82 is brought into contact with the front end portion of the guide groove 81 and the guide pin 82 is brought into contact with the rear end portion of the guide groove 81 as shown in FIG. It is possible to slide within the range between the front end position where the abutment is brought into contact.

  The slide member 72 is guided manually by the extending portions 105 on both sides of the counter main body 101 shown in FIG. 2, the insole constituting portion 71 shown in FIG. 4, and the left and right guide pins 82 shown in FIGS. Slide back and forth. When the manual operation is released, the slide member 72 is maintained in a stopped state at an arbitrary position mainly by the frictional force between the extending portions 105 on both sides and the insole constituting portion 71.

  As shown in FIG. 4, a detected portion 84 that protrudes outward in the left-right direction is integrally provided on one wall 77 side of the slide member 72. The detected portion 84 has a shape extending in the sliding direction of the slide member 72 as shown in FIG. As shown in FIG. 4, in the side wall portion 102 of the counter body 101 on the same side as the detected portion 84, a plurality of position detecting sensors shown in FIG. 85, 86, 87, 88 are arranged in this order from the rear to the front.

  The position detection sensor 85 is an optical sensor composed of a light emitting element 85a and a light receiving element 85b. In a state where the light receiving element 85b receives light emitted from the light emitting element 85a, there is no detected portion 84 between them. In a state where the light receiving element 85b does not receive the light emitted from the light emitting element 85a, it is detected that the detected portion 84 is between them. Similarly, for the position detection sensors 86 to 88, the position detection sensor 86 is a light emitting element 86a and a light receiving element 86b, the position detection sensor 87 is a light emitting element 87a and a light receiving element 87b, and the position detection sensor 88 is a light emitting element 88a and a light receiving element 88b. Respectively.

  The position detection sensor 85 located on the rearmost side is located at the rear end position where the slide member 72 including the receiving wall 32 is pushed most rearward with respect to the counter body 101 as shown in FIG. Sometimes it is provided at a position where the detected portion 84 is detected. Further, as shown in FIG. 6B, the position detection sensor 88 located on the foremost side is located at the front end position where the slide member 72 including the receiving wall 32 is most pulled out with respect to the counter body 101. 84 is provided at a position where 84 is not detected. And the position detection sensors 85-88 detect that the slide member 72 containing the receiving wall 32 is located in a front side, so that there are few things to detect the to-be-detected part 84. FIG. In other words, the position detection sensors 85 to 88 detect that the slide member 72 including the receiving wall 32 is located on the rear side as the number of the detected parts 84 is increased.

  The plurality of position detection sensors 85 to 88 arranged in the front and rear form a position detection unit 90 that detects a stop position in the front and rear direction of the slide member 72 including the receiving wall 32. Here, the residual discharge detection sensor 65 shown in FIG. 1 detects the presence or absence of the sheets S of the stacking unit 30 regardless of the position of the slide member 72 in the front-rear direction.

  As shown in FIG. 2, an operation unit 110 and a display unit 111 are provided on the upper front surface of the counter body 101 of the paper sheet counter 1. Further, inside the counter body 101, a storage unit 115 and a control unit 116 (integrated thickness detection means, control means, clear means) shown in FIG. 3 are provided.

  Here, the control unit 116 can select and set the identification item of the identification counting unit 41 in advance by an operation input to the operation unit 110. For example, when counting bills as the paper sheet S, the identification counting unit 41 identifies authenticity, correctness, and normality of the denomination. Is counted, whether the length in the transport direction is normal or abnormal.

  In the paper counting machine 1 described above, when an operator sets a group of paper sheets to be counted in the hopper 11 of the paper counting machine 1 in an accumulated state, and a start operation is input to the start button of the operation unit 110. The control unit 116 starts the counting process. In starting the counting process, the control unit 116 first determines the detection state of the detected portion 84 of the position detection sensors 85 to 88 of the position detection unit 90. Then, the fullness determination thickness Tm that is the fullness determination amount of the stacking of the paper sheets S of the stacking unit 30 is determined according to the detection state of the detected portions 84 of the position detection sensors 85 to 88. Specifically, the accumulation fullness determination thickness Tm of the accumulation unit 30 stored for each of the detection states of the detected portions 84 of the position detection sensors 85 to 88 is read from the storage unit 115. The fullness determination thickness Tm of stacking is an allowable maximum value of the stacking thickness of the paper sheets S stacked on the stacking unit 30.

  That is, in the storage unit 115, as shown in FIG. 6A, the first full determination thickness Tm <b> 1 when all the position detection sensors 85 to 88 detect the detected portion 84, and the rear end The second fullness determination thickness Tm2 is set in advance when the position detection sensor 85 does not detect the detected portion 84 and all the position detection sensors 86 to 88 on the front side thereof detect the detected portion 84. It is remembered. Further, in the storage unit 115, the two position detection sensors 85 and 86 from the rear end do not detect the detected part 84 and the front side position detection sensors 87 and 88 detect the detected part 84. When the third fullness determination thickness Tm3 and the three position detection sensors 85 to 87 from the rear end do not detect the detected portion 84, and only the foremost position detection sensor 88 detects the detected portion 84. The fourth fullness determination thickness Tm4, and the fifth fullness determination thickness Tm5 when all the position detection sensors 85 to 88 do not detect the detected portion 84 as shown in FIG. Is preset and stored.

  Here, the first to fifth fullness determination thicknesses Tm1 to Tm5 are maximum values in a range where the occurrence rate of the jam of the paper sheets S is lower than a predetermined ratio in the stacking unit 30, and are previously simulated or experimentally performed. Is set in Therefore, the second fullness determination thickness Tm2 is larger than the first fullness determination thickness Tm1, the third fullness determination thickness Tm3 is larger than the second fullness determination thickness Tm2, and the third The fourth fullness determination thickness Tm4 is larger than the fullness determination thickness Tm3, and the fifth fullness determination thickness Tm5 is larger than the fourth fullness determination thickness Tm4.

  If all the position detection sensors 85 to 88 have detected the detected portions 84 in the determination of the detection state of the detected portion 84 by the position detection portion 90 described above, the control portion 116 determines the first full determination thickness Tm1. Is read from the storage unit 115, and the first full determination thickness Tm1 is set to the full determination thickness. That is, the first full determination thickness Tm1 is determined as the full determination thickness. If only the position detection sensors 86 to 88 detect the detected portion 84, the control unit 116 reads the second fullness determination thickness Tm2 from the storage unit 115 and sets it to the fullness determination thickness. If only the position detection sensors 87 and 88 detect the detected portion 84, the control unit 116 reads the third fullness determination thickness Tm3 from the storage unit 115 and sets it to the fullness determination thickness. If only the position detection sensor 88 detects the detected portion 84, the control unit 116 reads the fourth fullness determination thickness Tm4 from the storage unit 115 and sets it to the fullness determination thickness. If none of the position detection sensors 85 to 88 detect the detected portion 84, the control unit 116 reads the fifth fullness determination thickness Tm5 from the storage unit 115 and sets this as the fullness determination thickness. .

  As described above, the control unit 116 and the storage unit 115 determine the fullness determination amount of the stacking unit 30 based on the detection result of the position detecting unit 90 including the position detection sensors 85 to 88. At that time, the accumulated thickness of the sheets S accumulated in the accumulating unit 30 is calculated as the full determination amount, that is, the full determination thickness.

  Next, the control unit 116 sets the rotation speed of the counting motor 15 to a predetermined counting rotation speed that is set in advance and stored in the storage unit 115, and the rotation speed of the integrated discharge vehicle motor 27 is set in advance. Are driven as predetermined integrated discharge vehicle rotation speeds stored in the storage unit 115. Then, the transport roller 24 and the integrated discharge wheel 25 are rotated. Next, the control unit 116 connects the clutch 16. Then, the kick roller 12 and the feeding roller 13 rotate together, and the sheets S in the sheet group loaded and placed in the hopper 11 are separated one by one and sequentially sent out to the transport unit 22. The paper sheet S sent to the transport unit 22 is transported toward the stacking unit 30 by the transport roller 24. At that time, the identification and counting unit 41 performs identification and counting, and the thickness detection unit 51 is detected. After the thickness is detected at, it is fed to the integrated discharge vehicle 25 and discharged from the integrated discharge vehicle 25 to the stacking unit 30. At that time, the paper sheets S are stacked in order from the front to the rear so that they are pushed forward in the standing state, moved on the bottom 31 of the stacking unit 30 and leaned against the receiving wall 32.

  After the start operation is input to the start button of the operation unit 110, the control unit 116 sequentially accumulates the thickness t of the sheets S detected by the thickness detection unit 51 to calculate and store the accumulated value Σak. Yes. For example, after the start operation is input, five sheets S are detected by the counting sensor 42, and the thickness t detected by the thickness detection unit 51 of these sheets S is t1, t2, t3, t4, and t5. If there is, the cumulative value Σak = t1 + t2 + t3 + t4 + t5 is calculated and stored. The accumulated value Σak is an accumulation thickness that is an accumulation amount of the sheets S of the accumulation unit 30 at the time when the sheet S having the thickness t last added to the accumulation value Σak is discharged to the accumulation unit 30. T. That is, the control unit 116 detects the accumulated thickness T of the sheets S of the accumulating unit 30 from the cumulative value Σak of the thickness t of the sheets S detected by the thickness detecting unit 51.

  Then, the controller 116 determines that the accumulated value Σak of the thickness t of the paper sheet S detected by the thickness detector 51 is determined according to the position of the slide member 72 including the receiving wall 32. When the determination thickness Tm is reached (that is, Σak ≧ Tm), the time when the sheet S having the thickness t finally added to the cumulative value Σak is discharged to the stacking unit 30, that is, the sheet S of the stacking unit 30 When the stacking thickness T, which is the stacking amount, reaches the full determination thickness Tm, the feeding unit 21 feeds the paper sheet S, the transporting unit 22 transports the paper sheet S, and the paper to the stacking unit 30. The discharge of the leaves S is temporarily stopped and the counting process is interrupted.

  Specifically, when the control unit 116 reaches the full determination thickness Tm for which the cumulative value Σak is set, the sheet S in which the thickness t is finally added to the cumulative value Σak is discharged to the stacking unit 30. At the time, the counting motor 15 is stopped, the clutch 16 is disconnected, and the feeding roller 13 and the kicking roller 12 are stopped by the brake 17. Further, the control unit 116 stops the integrated discharge vehicle motor 27 simultaneously with the stop of the counting motor 15. When the counting motor 15 and the integrated discharge vehicle motor 27 are stopped, the transport roller 24 and the integrated discharge vehicle 25 are also stopped, and the sheet S next to the sheet S in which the thickness t is added to the accumulated value Σak at the end. Even if it remains in the transport unit 22, it is not discharged to the stacking unit 30.

  If the feeding interval of the sheet S of the feeding unit 21 is set so that the next sheet S is fed when the fed sheet S is discharged to the stacking unit 30, the feeding unit When the feeding of the 21 sheets S is stopped, the sheet S basically does not remain in the transport unit 22. In this case, once the feeding of the paper sheet S by the feeding unit 21 is stopped, the transport and discharge of the paper sheet S are stopped even if the downstream transport unit 22 maintains the driving state. Therefore, the control unit 116 does not stop the counting motor 15 and the integrated discharge vehicle motor 27, disengages the clutch 16, and stops the feeding roller 13 and the kicking roller 12 by the brake 17. Thus, the feeding of the paper sheet S and the transport of the paper sheet S to the stacking unit 30 by the transport unit 22 are stopped. Of course, the counting motor 15 and the integrated discharge vehicle motor 27 may be stopped in the case where the paper sheet S is fed out.

  Specifically, if all the position detection sensors 85 to 88 detect the detected portion 84, the control unit 116 determines that the accumulated thickness T of the sheets S of the accumulation unit 30 is the first full determination thickness Tm1. Is reached, the feeding of the paper sheet S by the feeding unit 21 and the conveyance of the paper sheet S by the transport unit 22 are temporarily stopped. Further, if only the position detection sensors 86 to 88 detect the detected portion 84, when the accumulated thickness of the sheets S of the accumulation portion 30 reaches the second full determination thickness Tm <b> 2, the paper by the feeding portion 21. The feeding of the leaves S and the transport of the paper sheets S by the transport unit 22 are temporarily stopped. Further, if only the position detection sensors 87 and 88 detect the detected portion 84, when the accumulated thickness T of the sheets S of the accumulation portion 30 reaches the third full determination thickness Tm3, the feeding portion 21 The feeding of the paper sheet S and the conveyance of the paper sheet S by the conveying unit 22 are temporarily stopped. Further, if only the position detection sensor 88 detects the detected portion 84, when the accumulated thickness T of the sheets S of the accumulating portion 30 reaches the fourth fullness determination thickness Tm 4, the sheet S by the feeding portion 21. And the conveyance of the paper sheet S by the conveyance unit 22 are temporarily stopped. If none of the position detection sensors 85 to 88 detect the detected portion 84, the feeding portion 21 determines that the accumulation thickness T of the sheets S of the accumulation portion 30 reaches the fifth fullness determination thickness Tm 5. The feeding of the paper sheet S and the conveyance of the paper sheet S by the conveying unit 22 are temporarily stopped.

  From the state where the transport of the paper sheet S by the transport unit 22 and the discharge of the paper sheet S to the stacking unit 30 by the transport unit 22 are temporarily stopped as described above, the paper sheet S of the stacking unit 30 changes from the presence of the paper sheet to the absence of the paper sheet. When the discharge residual detection sensor 65 detects that the state has been reached, the control unit 116 clears the accumulated value Σak, that is, the accumulated thickness T, which is the accumulated amount of the sheets S of the accumulating unit 30 to 0, and the counting motor 15. In addition, the integrated discharge vehicle motor 27 is driven, the brake 17 is released, and the clutch 16 is engaged, so that the feeding of the paper S by the feeding unit 21 and the conveyance and discharging of the paper S by the transporting unit 22 are resumed. . That is, the counting process is resumed.

  When the above detection process 18, the counting and counting unit 41, and the conveyance residual detection sensor 61 detect that the sheet S is not present in the hopper 11 and the conveyance unit 22, the control unit 116 performs the counting motor 15 and the integration. The discharge vehicle motor 27 is stopped, the clutch 16 is disconnected, the brake 17 is applied, the feeding of the paper S by the feeding unit 21 and the conveyance of the paper S by the transporting unit 22 are stopped, and the paper of the stacking unit 30 is stopped. The accumulated value Σak which is the accumulation amount of the leaves S, that is, the accumulation thickness T is cleared to 0, the counting result of the identification counting unit 41 is displayed on the display unit 111, and the current counting process is terminated.

  Of course, after the start of the counting process, the fullness determination thickness in which the cumulative value Σak of the thickness t of the paper sheet S detected by the thickness detection unit 51 is determined according to the position of the slide member 72 including the receiving wall 32. Even when the insertion detection sensor 18, the identification counting unit 41, and the conveyance residual detection sensor 61 detect that there is no paper sheet S in the hopper 11 and the conveyance unit 22 without reaching the length Tm, the control unit 116 The same control is performed. That is, the control unit 116 stops the feeding of the paper sheet S by the feeding unit 21 and the conveyance of the paper sheet S by the transporting unit 22, and the accumulated value Σak that is the accumulation amount of the paper sheets S of the stacking unit 30, that is, the accumulation thickness. T is cleared to 0, the counting result of the identification counting unit 41 is displayed on the display unit 111, and the counting process is terminated.

  In the above description, the near full determination thickness Tn smaller than the full determination thickness Tm is set according to the position of the slide member 72 including the receiving wall 32, and the accumulated value Σak, that is, the accumulation of the sheets S of the accumulation unit 30 is set. When the thickness T reaches the near-full determination thickness Tn, the feeding speed of the paper sheet S by the feeding section 21 and the transport speed of the paper sheet S by the transport section 22 may be lowered and intermittent feeding may be performed. Thereby, it is possible to notify the operator that the vehicle is almost full.

  According to the present embodiment described above, the stacking unit 30 that allows the sheets S discharged from the transport unit 22 to be received by the front receiving wall 32 in a standing position and stacked in the front-rear direction and taken out outside the apparatus. The receiving wall 32 is slidable in the front-rear direction. For this reason, when it is desired to reduce the size of the fuselage, it is possible to reduce the size by positioning the receiving wall 32 constituting the front of the fuselage at the rear position, and when it is desired to increase the accumulation amount of the accumulation unit 30. Can be increased by placing the receiving wall 32 in the forward position.

  When the position detection unit 90 detects the stop position of the receiving wall 32 in the front-rear direction, the control unit 116 calculates the accumulation fullness determination amount of the accumulation unit 30 from the information stored in the storage unit 115 based on this. When the stacking amount of the sheets S of the stacking unit 30 detected based on the detection result of the thickness detecting unit 51 reaches the full determination amount, the control unit 116 feeds out and conveys the sheets S by the feeding unit 21. The conveyance of the sheets S to the stacking unit 30 by 22 is stopped. Therefore, even when the receiving wall 32 is slidable in the front-rear direction, the stacked amount of paper sheets S corresponding to the stop position of the receiving wall 32 can be stacked on the stacking unit 30. Therefore, regardless of the stop position of the receiving wall 32, it is possible to suppress the occurrence of jam that occurs when the accumulation amount is too large, and it is possible to suppress the decrease in counting efficiency that occurs when the accumulation amount is too small.

  Further, when the thickness detection unit 51 detects the thickness of the sheet S being moved by the transport unit 22, the control unit 116 accumulates the accumulated value of the thickness of the sheet S detected by the thickness detection unit 51. When the accumulated amount reaches the full determination amount, the feeding of the paper S by the feeding unit 21 and the conveyance of the paper S to the stacking unit 30 by the conveying unit 22 are stopped. Therefore, when counting a plurality of types of paper sheets S having different thicknesses, the occurrence of jam can be suppressed even when the thick paper sheets S are counted, and even when the thin paper sheets S are counted. A decrease in efficiency can be suppressed.

  According to the present embodiment described above, when the thickness detection unit 51 detects the thickness of the sheet S being moved by the transport unit 22, the control unit 116 detects the sheet S detected by the thickness detection unit 51. The accumulated thickness of the paper sheets S in the stacking unit 30 is detected from the accumulated value of the thicknesses. Therefore, when a plurality of types of paper sheets S having different thicknesses are processed, the accumulated thickness of the paper sheets S can be detected.

  Further, when the accumulation thickness of the sheets S of the accumulation unit 30 detected by the thickness detection unit 51 reaches the full determination thickness, the control unit 116 causes the conveyance unit 22 to convey the sheets S to the accumulation unit 30. Stop. Therefore, it is possible to suppress the occurrence of a jam that occurs when the integration thickness is increased, and it is possible to suppress a decrease in processing efficiency that occurs when the integration thickness is thin and stops.

  In addition, when the discharge residual detection sensor 65 that detects the presence or absence of the paper sheets S in the stacking unit 30 detects from the presence of paper sheets to the absence of paper sheets, the control unit 116 clears the stacking thickness of the stacking unit 30 up to that time. The processing can be automatically resumed. Therefore, a reduction in processing efficiency can be suppressed.

  In the above embodiment, the case where the slide member 72 is slid back and forth by manual operation has been described as an example. However, the slide member 72 may be slid by being driven by a motor. In that case, it is possible to detect the stop position of the slide member 72 by the rotation amount of the motor.

  In the above embodiment, the paper sheet counting machine 1 that counts the paper sheets S has been described as an example.
