The lid body part 52 is formed in a rectangular plate shape, and is attached to the vicinity of the upper end of the front side plate located on the front side of the main body part 51 via a predetermined hinge. Thereby, the lid body part 52 can open or close the upper side of the main body part 51 by rotating with respect to the main body part 51.

The main body portion 51 is provided with a partition plate 53 as a suppressing portion on the rear upper side. The partition plate 53 is, for example, a plate-shaped material that is bent to form a front partition plate 53F on the front side and a lower partition plate 53L on the lower side, and is arranged in a posture that resembles a capital letter "L" when viewed from the right side. , is attached to the main body part 51. Furthermore, a sub-partition plate 54 is attached to the main body portion 51 at the upper and rear sides of the partition plate 53 and approximately at the center in the left-right direction.

Thus, in the main body part 51, the front side or lower side of the partition plate 53 becomes the replenishment and collection storage 24, the right side of the sub partition plate 54 on the rear side or the upper side of the partition plate 53 becomes the first replenishment reject storage 25, and The left side portion of the sub-partition plate 54 on the rear side or above the partition plate 53 serves as a second replenishment reject store 26.

Incidentally, a passage hole for passing coins is formed in the lid part 52 at a location near the lower end of the guide part 30A (FIG. 2) and corresponding to the ceiling part of the replenishment and collection storage 24. Similarly, coins are also allowed to pass through the lid portion 52 at locations near the lower ends of the guide portions 30B and 30G and corresponding to the ceiling portions of the first refill reject store 25 and the second refill reject store 26. A passage hole is drilled for each.

A conveyor belt portion 55 is provided near the lower end of the replenishment and collection warehouse 24 . The conveyor belt section 55 includes four pulleys such as a driven pulley 61, a driving pulley 62, a tension pulley 63, and a bending pulley 64, a belt 65, left and right belt guides 67 (67L and 67R), and left and right guide protrusions. 70.

The driven pulley 61 is disposed near the lower front end of the replenishment and recovery warehouse 24, and is formed in a cylindrical shape with its central axis aligned in the left-right direction. This driven pulley 61 is rotatably supported by the main body portion 51.

The drive pulley 62 is located near the center of the rear side of the replenishment and collection warehouse 24 in the vertical direction, and is disposed at a position lower than the lower surface of the partition plate 53 and higher than the driven pulley 61. Like the driven pulley 61, the drive pulley 62 is formed in a cylindrical shape with its center axis aligned in the left-right direction, and is rotatably supported by the main body portion 51. Further, the drive pulley 62 is rotated in the direction indicated by arrow R1 or R2 in FIG. 4, that is, clockwise or counterclockwise, by being supplied with a driving force from a motor (not shown).

The tension pulley 63 is located at the same position (that is, the height) as the driven pulley 61 in the vertical direction, and is located in front of the drive pulley 62 in the front-back direction, and below the partition plate 53. There is. Like the driven pulley 61, the tension pulley 63 is formed in a cylindrical shape with its central axis aligned in the left-right direction, and is rotatably supported. Further, the driven pulley 61 is biased backward or downward by a biasing member (not shown).

The bending pulley 64 has an overall cylindrical shape with its central axis extending in the left-right direction, and is rotatably supported by the main body 51 . Further, the bending pulley 64 is located on the rear side of the driven pulley 61 and on the front side of the tension pulley 63, and further above the driven pulley 61 and the tension pulley 63, and above the belt 65.

The belt 65 as a conveyance member is an endless and wide belt, and is made of a flexible material such as rubber. Incidentally, the length of the belt 65 in the left-right direction is slightly larger than the diameter of the largest diameter coin (the largest diameter coin handled by the coin processing device 10, for example, a 500 yen coin). That is, the belt 65 can place coins in a lying state (with the plate surface facing upward and downward) on its upper surface.

This belt 65 is stretched around the driven pulley 61, the driving pulley 62, and the tension pulley 63, and between the driven pulley 61 and the driving pulley 62, the portions near both ends in the left and right direction are bent. It is arranged so as to be in contact with the lower side of the pulley 64. Along with this, the belt 65 has a belt flat part 65F that is substantially horizontal and flat on the front side of the part where it contacts the bending pulley 64, and a belt slope part 65S that is inclined with respect to the horizontal plane on the rear side. There is. This belt 65 can place coins accumulated in the accumulation space 50 on its surface (hereinafter also referred to as a conveying surface).

Further, as shown in FIG. 5, which is a cross-sectional view taken along line A1-A2 in FIG. 4, a plurality of belt protrusions 66 are provided on the outer surface (ie, the conveying surface) of the belt 65 and protrude outward from the periphery. The belt protrusions 66 serving as conveyance protrusions are arranged at two locations spaced apart from each other in the width direction (that is, the left-right direction) of the belt 65, and are arranged at predetermined intervals in the running direction of the belt 65. That is, on the surface of the belt 65, belt protrusions 66 are arranged in two rows in the left-right direction, spaced apart at predetermined intervals along the circumferential direction.

Therefore, in the belt flat portion 65F of the conveyor belt portion 55, a running locus 66L drawn by the belt protrusions 66 as the belt 65 runs is drawn in the shape of two bands in the front-rear direction. This belt protrusion 66 can cause the coin CN to travel together with the belt 65 by catching the coin CN when the belt 65 travels.

Incidentally, in the conveyor belt portion 55, the interval between the belt protrusions 66 in the left-right direction is shorter than the diameter of the smallest diameter coin (the smallest diameter coin handled in the coin processing device 10, for example, a 1 yen coin). Therefore, the conveyor belt portion 55 can reliably hook the coin CN without letting it slip through the gap between the belt protrusions 66.

The belt guide 67L (FIGS. 4 and 5) serving as a guide member is a part molded, for example, from a predetermined resin material by a method such as injection molding. It covers part of the neighborhood. The right end, that is, the inner end of the belt guide 67L is spaced apart from the traveling locus drawn by the belt protrusion 66 by a predetermined distance. This belt guide 67L has an inclined surface 68 forming the upper right surface and a protrusion 69 formed on the inclined surface 68.

The inclined surface 68 is formed in a planar shape connecting the upper left side and the lower right side. This inclined surface 68 has an angle α (hereinafter referred to as this) which is an inclined angle with respect to the belt flat portion 65F, as shown in FIG. 6, which is a cross-sectional view taken along B1-B2 in FIG. (also referred to as the first angle) is approximately 45 degrees. Further, a guide hole 68H penetrating in the left-right direction is provided near the center of the inclined surface 68 in the front-rear direction and slightly above the lower end.

The protruding portion 69 slightly projects from the inclined surface 68 toward the upper right, and is formed in an elongated straight line connecting the upper left side and the lower right side. A plurality of protrusions 69 are provided on the inclined surface 68 at predetermined intervals along the front-rear direction. The distance between the protrusions 69 (FIG. 5) in the front-rear direction is smaller than the diameter of the smallest coin (ie, the diameter of a 1-yen coin). Further, some of the protrusions 69 have protrusion end protrusions 69P formed by protruding more toward the upper right in the vicinity of the lower ends than the other portions.

On the other hand, although the right belt guide 67R is configured to be approximately symmetrical with the left belt guide 67L, the positions of the respective protrusions 69 and guide holes 68H in the front-rear direction are different from the left belt guide 67L. It is shifted forward by an offset distance L1. This offset distance L1 is, for example, about 1/2 to 1/3 of the diameter of the smallest coin (that is, the diameter of a 1 yen coin), and about half the period of the position of each protrusion 69 in the front-rear direction. ing.

As shown in FIG. 7, the guide protrusion 70 serving as a contact portion is attached to the main body frame 56, and is composed of a protrusion 71 and a guide protrusion support member 72. Incidentally, the guide protrusion 70 is configured to be substantially symmetrical on the left and right sides. Therefore, in the following description, the left guide protrusion 70 will be described as an example.

As shown in FIGS. 4 and 5, the protrusion 71 is provided so as to be embedded in a guide hole 68H formed in the inclined surface 68. As shown in a schematic three-view diagram in FIG. 8, the protrusion 71 is formed into a cylindrical shape centered on a virtual axis 71C along the left-right direction as a whole. Incidentally, the protrusion 71 is made of a metal material such as stainless steel, and is manufactured, for example, by cutting, polishing, or the like on an elongated cylindrical stainless steel material. That is, the protrusion 71 is made of a different material from the belt guide 67 made of a resin material.

Roughly divided along the axis 71C, the protrusion 71 includes a right end portion 81, a central portion 82 near the center, and a left end portion 83. Hereinafter, the right side where the tip portion 81 is located is also referred to as the tip side, and the left side where the distal end portion 83 is located is also referred to as the distal side.

The tip portion 81 is formed into a conical shape centered on the axis 71C, and a portion corresponding to a predetermined distance from the apex (ie, right end) of the cone is shaved off and rounded into a spherical shape. This tip portion 81 has an apex angle of about 60 degrees when viewed from the front-rear direction and the up-down direction, and an angle β (hereinafter referred to as a second angle), which is the angle between the hypotenuse corresponding to the surface of the cone and the axis 71C. ) is about 30 degrees. Further, a portion of the tip portion 81 below the axis 71C is cut by a plane substantially parallel to the axis 71C, thereby forming a first lower surface 91.

The central portion 82 has a basically cylindrical shape centered on the axis 71C and has the same diameter as the root side portion (that is, the left side portion) of the tip portion 81. Further, the center portion 82 has a lower portion cut off in the range of about 1/3 to about 2/5 of the tip portion 81 side (that is, the right side) in the same manner as the tip portion 81, so that the center portion 82 is A planar second lower surface 92 that is continuous with the first lower surface 91 is formed. Further, the central portion 82 includes a portion lower than the second lower surface 92 in a range of approximately 2/3 to 3/4 of the distal end portion 83 side (i.e., the left side) and the tip portion 81 side (i.e., the right side). By cutting, a third lower surface 93 that is substantially parallel to the second lower surface 92 is formed. Further, the end portion 83 is formed into a cylindrical shape that is one size smaller in diameter than the center portion 82, that is, one size smaller.

In addition, the central portion 82 has a first stepped surface 94, a second stepped surface 95, and a third stepped surface 96, all of which are planes perpendicular to the axis 71C. The first stepped surface 94 connects the distal end of the second lower surface 92 and the distal end of the third lower surface 93. The second stepped surface 95 connects the distal end of the third lower surface 93 and the vicinity of the lower end of the outer peripheral surface. The third stepped surface 96 connects the distal end of the distal portion 83 and the distal end of the central portion 82 .

The guide protrusion support member 72 (FIG. 7) is manufactured by cutting and bending a relatively small plate-shaped metal plate, and is bent into a crank shape when viewed from the front and rear directions, so that the guide protrusion support member 72 (FIG. 7) is formed by cutting and bending a relatively small metal plate. On the other hand, the upper part 72U is located on the left side. A guide protrusion insertion hole 72UH, which is a round hole penetrating in the left-right direction, is bored in the upper portion 72U. The diameter of this guide protrusion insertion hole 72UH is slightly larger than the diameter of the end portion 83 of the protrusion 71. The lower portion 72L is fixed to the left side surface of the main body frame 56 with a predetermined mounting screw.

The main body frame 56 is a component that constitutes a part of the main body part 51 (FIG. 3), and is manufactured by appropriately cutting and bending a plate-shaped metal member that is relatively large and has a sufficient thickness. The main body frame 56 appropriately supports each component of the conveyor belt section 55, and a belt guide 67L is attached thereto. Further, the main body frame 56 is provided with a frame hole 56H that penetrates in the left-right direction on the left side of the guide hole portion 68H of the belt guide 67L. Although this frame hole 56H is generally circular and has a slightly larger diameter than the diameter of the central portion 82 of the protrusion 71 in the front-rear direction, a portion near the lower end is narrowed and formed into a straight line. ing.

As shown in FIG. 7, when the guide protrusion 70 is manufactured, a protrusion 71 is fixed to the main body frame 56 by a guide protrusion support member 72. Specifically, in the guide protrusion 70, first, the tip end 81 and center part 82 of the protrusion 71 are inserted from the left side of the main body frame 56 into the frame hole 56H and the guide hole 68H of the belt guide 67L. Next, in the guide protrusion 70, with the distal end 83 of the protrusion 71 inserted into the guide protrusion insertion hole 72UH of the guide protrusion support member 72, the lower part 72L of the guide protrusion support member 72 is screwed to the main body frame 56. be done.

Then, in the guide protrusion 70, the movement in the vertical direction and the front-back direction is restricted because the tip part 81 and the center part 82 of the protrusion 71 are inserted into the frame hole 56H and the guide hole part 68H. Further, in the guide protrusion 70 , the second step surface 95 of the protrusion 71 comes into contact with the left side surface of the main body frame 56 to restrict movement in the right direction, and the third step surface 96 of the guide protrusion support member 72 It comes into contact with the right side surface and movement to the left is restricted.

As a result, in the conveyor belt section 55, the protrusion 71 of the guide protrusion 70 is aligned with the axis 71C in the left-right direction and the first lower surface 91 and the second lower surface 92 are directed downward relative to the belt guide 67L. It becomes a fixed state.

Further, in the conveyor belt portion 55 (FIG. 7), the vicinity of the tip of the tip portion 81 of the protrusion 71 is made to protrude to the upper right side than the inclined surface 68 and the protrusion portion 69 above the belt flat portion 65F, and It is made to protrude to the right side of the lower end portion formed on the lower right side of the inclined surface 68.

Here, the tip of the protrusion 71 is located approximately 4 mm above the generally horizontal belt flat portion 65F. Furthermore, when focusing on the angle of inclination with respect to the belt flat portion 65F, the angle α between the inclined surface 68 and the protrusion 69 formed on the inclined surface 68 is about 45 degrees, while the tip of the protrusion 71 The angle β with the portion 81 is about 30 degrees. That is, in the conveyor belt portion 55, the tip portion 81 of the protrusion 71 is smaller than the inclined surface 68 and the protruding portion 69 with respect to the inclination angle with respect to the belt flat portion 65F that is substantially parallel to the horizontal direction.

Further, a discharge port 57 serving as a discharge portion is formed on the rear side surface of the main body portion 51 (FIGS. 3 and 4). The discharge port 57 is a square hole penetrating in the front-rear direction, and extends from the vicinity of the lower surface of the lower partition plate 53L to the vicinity of the upper end of the drive pulley 62 in the vertical direction, and from the vicinity of the left end of the main body portion 51 to the right end in the horizontal direction. It extends to the vicinity. Incidentally, the discharge port 57 can be opened and closed by a shutter (not shown).

With this configuration, the upper surface of the belt 65 of the conveyor belt section 55 forms the bottom surface of the accumulation space 50 formed inside the replenishment and collection storage 24 . That is, when the coins are guided by the guide section 30A (FIG. 2), the replenishment collection warehouse 24 allows the coins to pass through the passage hole of the lid body section 52 into the accumulation space 50, and is placed on the belt 65. Or collect them with other coins. Incidentally, in addition to the belt guide 67, other members forming an inner surface are appropriately provided inside the replenishment and collection storage 24 to prevent coins from entering gaps between parts.

Further, when a driving force is supplied to the drive pulley 62 from a motor (not shown), the conveyor belt section 55 rotates the drive pulley 62 clockwise in the direction of arrow R1 in FIG. The vehicle is caused to travel in the direction indicated by E1 (hereinafter also referred to as the forward direction). Thereby, the conveyor belt section 55 can convey the coins placed or accumulated on the belt 65 in the rear direction.

Incidentally, when the drive pulley 62 is rotated counterclockwise in the direction of arrow R2, the conveyor belt portion 55 rotates the belt 65 in the direction indicated by arrow E2 (hereinafter also referred to as the opposite direction), that is, in the opposite direction to arrow E1. run it. Thereby, the conveyor belt section 55 can convey the coins placed or accumulated on the belt 65 in the forward direction.

[1-4. Transport of coins]
Next, the conveyance of coins in the replenishment collection warehouse 24 will be explained. The replenishment collection warehouse 24 is removed as a coin cassette 31 from the coin processing device housing 11 (FIG. 2) by a worker or the like, and then the lid body part 52 is rotated upward with respect to the main body part 51. In the open state (FIG. 3), a plurality of coins for replenishment are inserted into the accumulation space 50. As a result, the replenishment collection warehouse 24 is in a state where the coins are accumulated on the belt 65 of the conveyor belt section 55 (FIG. 4), that is, within the accumulation space 50.

Next, the coin cassette 31 is loaded into the front loading section 11CF (FIG. 2) of the coin processing device housing 11 with the lid portion 52 (FIG. 3) closed. When the coin processing device 10 performs a replenishment process of transporting coins in the replenishment and collection warehouse 24 to the stacker section 21 based on an operation instruction from an operator or the like, the coin processing device 10 first transfers the coins in the replenishment and collection warehouse 24 based on the control of the coin control section 12. The coins stored in the coins are sequentially fed out to the lower separating section 29 on the rear side.

At this time, when the belt 65 of the conveyor belt section 55 runs in the forward direction, the belt protrusion 66 (see FIG. 5, etc.) provided on the belt 65 catches the coin at the bottom of the accumulation space 50. , transported to the rear. As a result, the replenishment collection warehouse 24 moves the coins in the accumulation space 50, centering on the portion near the lower end, on the belt flat portion 65F, then on the belt slope portion 65S, and then moves the coins from the discharge port 57 to the rear side. Coins can be fed out to the lower separating section 29 (FIG. 2).

By the way, when the number of coins stored in the replenishment collection warehouse 24 decreases, for example, as shown in a perspective view in FIG. 9 and a cross-sectional view and a side view in FIGS. 10(A) and (B), One coin CN may be in a state (that is, a standing state) leaning against the left belt guide 67L near the left end on the belt flat portion 65F. Here, when the coin processing device 10 handles Japanese coins CN, a 500 yen coin (hereinafter referred to as coin CN500) having the largest diameter among the coins CN that can be handled by the coin processing device 10 will be described.

As shown in FIG. 10(A), the right end of the coin CN500 is located to the left of the belt protrusion 66. For this reason, the coin CN500 is not caught on the belt protrusion 66 of the belt 65 when the belt 65 travels backward, which is the traveling direction. In other words, although the coin CN500 may move backward as the belt 65 travels, it may not be able to move forward if it gets caught in a surrounding guide or at a point where the belt changes from the flat part 65F to the belt slope part 65S. There is a possibility that it will run out and continue to rotate in place.

Here, in the replenishment collection warehouse 24, the diameter of the coin CN500 is about 26 [mm], and since it is leaning against the inclined surface 68 having an inclination angle of about 45 degrees with respect to the belt flat part 65F, its center of gravity is The center point (shown as the intersection of two thin lines in the figure) is located approximately 9.2 mm above the belt flat portion 65F. In addition, in the replenishment collection warehouse 24, the vicinity of the tip of the protrusion 71 protrudes to the upper right side from the inclined surface 68, and the tip is approximately 4 mm above the belt flat portion 65F, that is, from the center of gravity of the coin CN500. It is located at the bottom.

Therefore, in the replenishment and collection warehouse 24, when the coin CN500 is conveyed and comes into contact with the protrusion 71, as shown in FIGS. 11 and 12, which correspond to FIGS. The lower side of the center of gravity of the coin CN500 is guided so as to be pushed out to the right, and the vicinity of the lower end is brought into the range of the travel locus 66L of the belt protrusion 66. That is, the replenishment and collection warehouse 24 can change the posture of the coin CN500 from the standing state by the protrusion 71. Then, in the replenishment collection warehouse 24, as the belt 65 runs, the coin CN500 can be hooked on the belt protrusion 66, etc., and the coin CN500 can be smoothly conveyed.

Next, when the coin processing device 10 handles Japanese coins CN, a 1 yen coin (hereinafter referred to as coin CN1) having the smallest diameter among the coins CN that can be handled by the coin processing device 10 will be described. In FIGS. 13A and 13B, which correspond to FIGS. 10A and 10B, the coin CN1 is in an upright position, as in the case of coin CN500, and its right end is closer to the belt protrusion 66. It is also located on the left side. For this reason, the coin CN1 is not caught by the belt protrusion 66 of the belt 65 when the belt 65 travels backward, which is the traveling direction, as in the case of the coin CN500.

Here, in the replenishment collection warehouse 24, the diameter of the coin CN1 is about 20 [mm], and since it is leaning against the inclined surface 68, its center point, which is the center of gravity, is about 7.1 [mm] from the belt flat part 65F. It is located on the upper side, that is, above the vicinity of the tip of the protrusion 71.

Therefore, in the replenishment and collection warehouse 24, when the coin CN1 is conveyed and comes into contact with the projection 71, as shown in FIG. 14 corresponding to FIG. The lower side of the center of gravity of the coin CN1 is guided so as to be pushed out to the right, and the vicinity of the lower end is brought into the range of the travel locus 66L of the belt protrusion 66. That is, the replenishment and collection warehouse 24 can change the attitude of the coin CN1 from the standing state by the protrusion 71. Then, in the replenishment collection warehouse 24, the coin CN1 can be smoothly transported by hooking the coin CN1 on the belt protrusion 66 as the belt 65 runs, as in the case of the coin CN500.

Next, a 5 yen coin (hereinafter referred to as coin CN5) with a hole formed in the center will be explained. In FIGS. 15A and 15B, which correspond to FIGS. 10A and 10B, the right end of the coin CN5 is located to the left of the belt protrusion 66, as in the case of the coin CN500, etc. . For this reason, the coin CN5 is not caught by the belt protrusion 66 of the belt 65 when the belt 65 travels backward, which is the traveling direction, as in the case of the coin CN500 and the like.

Here, in the replenishment collection warehouse 24, the diameter of the coin CN5 is about 22 [mm], and since it is leaning against the inclined surface 68, its center point, which is the center of gravity, is about 7.8 [mm] from the belt flat part 65F. It is located on the upper side, that is, above the vicinity of the tip of the protrusion 71.

Therefore, in the replenishment and collection warehouse 24, when the coin CN5 is transported and comes into contact with the projection 71, as shown in FIG. 16 corresponding to FIG. As a result, the lower side of the center of gravity of the coin CN5 is pushed out to the right, and the vicinity of the lower end is brought into the range of the travel locus 66L of the belt protrusion 66. That is, the replenishment and collection warehouse 24 can change the posture of the coin CN5 from the standing state by the protrusion 71. Then, in the replenishment collection warehouse 24, the coin CN5 can be smoothly conveyed by hooking the coin CN5 on the belt protrusion 66 as the belt 65 runs, as in the case of the coin CN500 and the like.

By the way, the coin CN5 has a hole with a diameter of about 5 [mm] formed in its center. Therefore, if the tip of the protrusion 71 were to enter this hole, the coin CN5 would be caught in the protrusion 71, and its progress may be hindered. Therefore, in the replenishment collection warehouse 24, the shape, distance, angle, etc. of each part are appropriately set according to the diameter of the coin CN5 and the diameter of the hole, so that the tip of the protrusion 71 fits into the hole of the coin CN5. It is designed not to get caught.

Specifically, in the replenishment collection warehouse 24, the angle α (45 degrees, FIG. 8) of the inclined surface 68 with respect to the belt flat portion 65F, and the angle β (30 degrees, FIG. ), the height from the belt flat portion 65F (approximately 4 [mm]), etc. are appropriately set. In addition, in the replenishment and collection warehouse 24, a portion of the tip 81 of the protrusion 71 corresponding to a predetermined distance from the apex of the conical shape is shaved off and rounded (FIG. 6).

As a result, in the replenishment collection warehouse 24, even if part of the tip 81 of the protrusion 71 enters the hole of the coin CN5 as the belt 65 runs, it will not come out from the opposite side of the hole. When a force is applied to the coin CN5 from the belt protrusion 66, the protrusion 71 easily comes out of the hole of the coin CN5 and does not interfere with conveyance.

[1-5. Effects, etc.]
In the above configuration, the coin processing device 10 of the automatic teller machine 1 according to the first embodiment is installed at a location near the lower end of the inclined surface 68 with respect to the belt guide 67 (68L and 68R) of the replenishment and collection warehouse 24. A protrusion 71 was provided (FIGS. 3 to 8).

For this reason, when the coin is in an upright position leaning against the inclined surface 68 on the outside of the belt protrusion 66 of the belt 65, when the belt 65 is run, the replenishment and recovery storage 24 is located at a position lower than the center of gravity of the coin. The vicinity of the tip of the projection 71 can be brought into contact with the side. As a result, the replenishment collection warehouse 24 can guide the coins to the inside of the belt protrusions 66 of the belt 65, and eventually bring them into contact with the belt protrusions 66, and transport the coins by the force from the belt protrusions 66, so that the coins can be transported into the accumulation space. 50 can be effectively prevented.

In particular, in the replenishment/recovery storage 24, the tip of the protrusion 71 is located approximately 4 mm above the belt flat portion 65F. As a result, the replenishment collection warehouse 24 can handle any of the coins handled by the coin processing device 10, from the largest diameter (500 yen coin) to the smallest diameter (1 yen coin), by using the inclined surface 68 of the belt guide 67. Alternatively, when the coin is in an upright position leaning against the protrusion portion 69, the protrusion 71 can be brought into contact with a position lower than the center of gravity of the coin.

In addition, in the replenishment collection storage 24, the angle β of the tip portion 81 of the protrusion 71 is set to approximately 30 degrees with respect to the substantially horizontal belt flat portion 65F, which is smaller than the angle α of the inclined surface 68 of approximately 45 degrees. (Figure 7). Therefore, in the replenishment and recovery storage 24, the portion of the tip 81 that protrudes beyond the inclined surface 68 is only the uniform conical side surface and the spherical portion at the tip, and the tip 81 and the center portion 82 (FIG. 8) There is no need to position a bent shape such as a joint part. As a result, in the replenishment collection warehouse 24, when a coin comes into contact with the protrusion 71 as the belt 65 runs, it can be slid smoothly and the vicinity of the lower end can be guided within the running range of the belt protrusion 66.

Further, in the replenishment and collection warehouse 24, the belt guide 67 is a molded part made of a resin material. Therefore, in the replenishment collection warehouse 24, the belt guide 67 can be configured to appropriately surround the accumulation space 50 and have a shape suitable for guiding coins. Further, in the replenishment and collection warehouse 24, the protrusion 71 is made of stainless steel, which is a metal material. Therefore, in the replenishment and recovery warehouse 24, it is possible to suppress the protrusion 71 protruding from the inclined surface 68 from being worn out due to contact with coins.

Further, in the replenishment and collection warehouse 24, the positions of the respective protrusions 71 in the front-rear direction are separated by an offset distance L1 between the left belt guide 67L and the right belt guide 67R (FIG. 5). Therefore, in the replenishment and collection warehouse 24, when the belt 65 moves from the front side to the rear side in the accumulation space 50, the protrusions 71 can appear alternately from the right side and the left side. As a result, in the replenishment and collection warehouse 24, the problem that may occur when the protrusions 71 are provided in symmetrical positions, such as the width in the left and right direction near the surface of the belt 65 becoming extremely narrow, is avoided, such that coins become jammed. can.

According to the above configuration, the coin processing device 10 of the automatic teller machine 1 according to the first embodiment has a guide protrusion at a location near the lower end of the inclined surface 68 with respect to the conveyor belt portion 55 of the replenishment and collection warehouse 24. A section 70 was provided. For this reason, when a coin is in an upright position outside the belt protrusion 66 of the belt 65, the replenishment and collection storage 24 brings the vicinity of the tip of the protrusion 71 into contact with the lower side of the center of gravity of the coin. As a result, the replenishment collection warehouse 24 can guide the coins to the inner side of the belt protrusions 66 of the belt 65, can transport the coins by the belt protrusions 66, and can effectively prevent the coins from remaining in the accumulation space 50.

[2. Second embodiment]
An automated teller machine 201 (FIG. 1) according to the second embodiment is different from the automated teller machine 1 according to the first embodiment in that it includes a coin processing device 210 instead of the coin processing device 10. However, in other respects they are structured similarly. The coin processing device 210 (FIG. 2) is different from the coin processing device 10 according to the first embodiment in that it includes a replenishment collection storage 224 instead of the replenishment collection storage 24, but the other points are the same. It is composed of

The replenishment collection warehouse 224 (FIG. 4) is different from the replenishment collection warehouse 24 according to the first embodiment in that it includes a conveyor belt section 255 in place of the conveyor belt section 55, but is otherwise similar. It is composed of The conveyor belt section 255 (FIGS. 4 and 5) is different from the conveyor belt section 55 according to the first embodiment in that it has a guide protrusion 270 instead of the guide protrusion 70, but has other points. are structured in the same way.

As shown in FIGS. 17 and 18, which correspond to FIGS. 6 and 7, the guide protrusion 270 as an abutment part is formed by the protrusion 71 of the guide protrusion 70 and the guide protrusion support member 72 according to the first embodiment. Instead, it has a protrusion 271 and a guide protrusion support member 272, and further includes a spring 273.

The protrusion 271 as an abutting body has a tip part 81, a central part 82, and a similar part to the protrusion 71 according to the first embodiment, as shown in a schematic three-view diagram in FIG. 19, which corresponds to FIG. In addition to the distal end 83, it has a second end 284. The second end portion 284 is provided on the left end side of the end portion 83 and has a cylindrical shape that is slightly thinner (that is, has a shorter diameter) than the end portion 83 . Incidentally, like the protrusion 71 according to the first embodiment, the protrusion 271 is manufactured, for example, by cutting, polishing, or the like on an elongated cylindrical stainless steel material.

The guide protrusion support member 272 (FIG. 18), like the guide protrusion support member 72 according to the first embodiment, is manufactured by cutting and bending a relatively small plate-shaped metal plate, and when viewed from the front and rear directions. By being bent into a crank shape, the upper part 272U is located on the left side of the lower part 272L. However, in the guide protrusion support member 272, the distance between the lower part 272L and the upper part 272U in the left-right direction is larger than that of the guide protrusion support member 72 in the first embodiment, and the distal end 83 of the protrusion 271 along the axis 71C and the second end portion 284.
It's getting bigger.

Similar to the upper part 72U, the upper part 272U is provided with a guide protrusion insertion hole 272UH, which is a round hole that penetrates in the left-right direction. However, unlike the first embodiment, the diameter of the guide projection insertion hole 272UH is smaller than the diameter of the end portion 83 of the projection 271 and slightly larger than the diameter of the second end portion 284. The lower portion 272L, like the lower portion 72L, is fixed to the left side surface of the main body frame 56 with a predetermined mounting screw.

The spring 273 is a so-called coil spring, and its inner diameter is larger than the diameter of the end portion 83 of the protrusion 271 and smaller than the diameter of the central portion 82. Further, the natural length of the spring 273 is equal to or greater than the distance between the lower portion 272L and the upper portion 272U in the left-right direction.

As shown in FIG. 18, the guide protrusion 270 is attached to the main body frame 56 with the guide protrusion support member 272 sandwiching the protrusion 271 and the spring 273 during manufacture. Specifically, in the guide protrusion 270, the tip end 81 and center part 82 of the protrusion 271 are first inserted from the left side of the main body frame 56 into the frame hole 56H and the guide hole 68H of the belt guide 67L. Next, in the guide protrusion 270, with the spring 273 inserted through the end 83 and second end 284 of the protrusion 71, the guide protrusion insertion hole 272UH of the guide protrusion support member 272 is inserted while compressing the spring 273. The lower portion 272L of the guide protrusion support member 272 is inserted through the second end portion 284 and screwed to the main body frame 56.

Then, in the guide protrusion 270, as in the first embodiment, the tip part 81 and the center part 82 of the protrusion 271 are inserted into the frame hole 56H and the guide hole part 68H, so that the guide protrusion 270 moves in the vertical direction and the front-back direction. movement is regulated. In addition, in the guide protrusion 270, since the spring 273 is compressed from its natural length, the restoring force acts on the upper part 272U of the guide protrusion support member 272 to the left (end side), and the protrusion A force is applied to the third stepped surface 96 of 271 to the right (toward the tip side). As a result, the protrusion 271 as a whole is biased toward the right side, and the second stepped surface 95 is brought into contact with the left side surface of the main body frame 56 .

As a result, as shown in FIG. 20A, which corresponds to FIG. It will be in a state where it is protruded to the upper right side. Hereinafter, this will be referred to as a protruding state. Incidentally, for convenience of explanation, FIG. 20(A) shows a cross-sectional view passing through the axis 71C (FIG. 19) of the protrusion 271.

Furthermore, by appropriately selecting the spring constant of the spring 273, the guide protrusion 270 does not contract when a force weaker than a predetermined reference force is applied, and does not contract when a force weaker than a predetermined reference force is applied. It is designed to contract when a large (large) force is applied.

This reference force is, for example, when one coin CN collides with the tip 81 of the protrusion 271 in a situation where the belt 65 is conveying the coins CN at a predetermined conveyance speed in the replenishment collection warehouse 224. Due to the slope of the front side portion of 81, the force is greater than the relatively weak force acting toward the distal side. Hereinafter, this relatively weak force will be referred to as a coin impact force or a medium impact force.

Further, this reference force is based on the condition that, for example, in a situation where a large amount of coins CN are accumulated in the accumulation space 50 in the replenishment collection warehouse 224, a downward force due to the weight of these coins CN is applied to the tip 81 of the protrusion 271. In this case, the slope of the upper surface portion of the distal end portion 81 is smaller than the relatively strong force acting toward the distal end. Hereinafter, this relatively strong force will be referred to as the accumulated coin loading force or the accumulated medium loading force.

Here, when a force larger than the reference force is applied to the tip 81 of the protrusion 271 toward the left end, the guide protrusion 270 moves toward the distal end while contracting the spring 273, as shown in FIG. 20(B). As shown, the process stops when the fourth step surface 297 of the protrusion 271 comes into contact with the upper part 272U of the guide protrusion support member 272. At this time, the protrusion 271 is in a state in which the tip portion 81 is recessed into the guide hole 68H of the belt guide 67, that is, in a buried state. As a result, the replenishment collection storage 224 is in a state in which the protrusion 271 of the guide protrusion 270 is retracted to the left side of the slope 68, that is, to the outside of the accumulation space 50, so that the coins in the accumulation space 50 are not obstructed. can proceed. Therefore, in the following, such a state will be referred to as a save state.

In this way, the guide protrusion 270 moves the protrusion 271 in the left-right direction in accordance with the applied external force, so that a part of the protrusion 271 protrudes into the accumulation space 50 (see FIG. 20(A)). ), or the protrusion 271 can be retracted into the guide hole 68H and retracted outside the accumulation space 50 (FIG. 20(B)). In other words, the spring 273 maintains the protrusion 271 in a protruding state when one coin CN collides with the tip 81, and the load from the large number of accumulated coins CN acts on the tip 81. The spring constant is appropriately selected so that the state transitions to the retracted state when

Therefore, in the guide protrusion 270, when a coin collision force weaker than the reference force is applied to the distal end 81 of the protrusion 271, the spring 273 is not contracted and the spring 273 is in the protruding state (see FIG. 20). A)) maintain. On the other hand, in the guide protrusion 270, when an accumulated coin load force stronger than the reference force is applied to the tip 81 of the protrusion 271, the protrusion 271 is moved toward the distal end while the spring 273 is contracted. Ru. Furthermore, if the force applied at this time is sufficiently large, the guide protrusion 270 transitions to the retracted state (FIG. 20(B)).

For example, in the replenishment collection warehouse 224, a relatively large amount of coins is accumulated in the accumulation space 50, and the coins are accumulated not only above the conveyor belt section 255 but also above the inclined surface 68 of the belt guide 67 and the protrusion 271. may be done. In this case, in the replenishment collection warehouse 224, an accumulated coin load force stronger than the reference force is applied from a large amount of coins to the tip 81 of the protrusion 271, so the spring 273 contracts and the protrusion 271 is in the retracted state. (FIG. 20(B)).

In addition, in the replenishment and collection warehouse 224, when a large amount of coins is delivered from the discharge port 57 (FIGS. 4 and 5) by running the belt 65 of the conveyor belt section 255, the number of coins in the accumulation space 50 becomes relatively small. . In this case, in the replenishment collection warehouse 224, the force applied from the coins remaining in the accumulation space 50 to the tip 81 of the protrusion 271 becomes relatively weak (small), so the restoring action of the spring 273 causes the protrusion The body 271 transitions from the retracted state (FIG. 20(B)) to the protruded state (FIG. 20(A)).

In the above configuration, the coin processing device 10 of the automatic teller machine 201 according to the second embodiment collects coins accumulated in the accumulation space 50 using the replenishment collection warehouse 224, as in the first embodiment. It is transported by the transport belt section 255. As in the case shown in FIGS. 9 and 10, the replenishment collection storage 224 is in an upright state in which one coin CN500 is leaning against the left belt guide 67L near the left end on the belt flat portion 65F. , as the belt 65 runs, the coin CN500 is conveyed and brought into contact with the protrusion 271.

At this time, the replenishment collection warehouse 224 maintains the guide protrusion 270 in the protruding state (FIG. 20(A)), and as shown in FIGS. The lower side of the center of gravity is guided so as to be pushed out to the right, and the vicinity of the lower end reaches within the range of the locus of the belt protrusion 66.

That is, like the first embodiment, the replenishment collection warehouse 224 can change the posture of the coin CN500 from the standing state using the protrusion 271. Then, in the replenishment collection warehouse 224, as the belt 65 runs, the coin CN500 can be hooked onto the belt protrusion 66, thereby smoothly transporting the coin CN500.

Similarly, for coins of other denominations, such as coins CN1 and coins CN5, if one coin is in an upright position, the replenishment collection warehouse 224 also changes its posture by bringing the protrusion 271 into contact with the coin. It can be conveyed by breaking it down and hooking it onto the belt protrusion 66.

Furthermore, as shown in FIG. 21, if a plurality of coins are being conveyed by the belt 65 between the left and right belt guides 67 while leaning against each other, the replenishment collection warehouse 224 will be able to transport these coins. At the stage when the coin abuts the protrusion 271 of the guide protrusion 270, the protrusion 271 can be moved to the retracted state (FIG. 20(B)). As a result, the replenishment collection warehouse 224 can avoid a situation in which coins are caught on the guide protrusion 270 and transportation is obstructed.

In other respects as well, the replenishment collection warehouse 224 according to the second embodiment can have the same effects as the replenishment collection warehouse 24 according to the first embodiment.

According to the above configuration, the coin processing device 210 of the automatic teller machine 201 according to the second embodiment has a guide protrusion at a location near the lower end of the inclined surface 68 with respect to the conveyor belt portion 55 of the replenishment and collection warehouse 224. A section 270 is provided. Therefore, when a coin is in an upright position outside the belt protrusion 66 of the belt 65, the replenishment collection storage 224 guides the coin inward by bringing the vicinity of the tip of the protrusion 271 into contact with the coin. As a result, the replenishment collection warehouse 224 can transport the coins using the belt protrusion 66, and can effectively prevent the coins from remaining in the accumulation space 50. Furthermore, when a force equivalent to a plurality of coins is applied to the protrusion 271, the replenishment collection storage 224 moves the protrusion 271 from the protruding state to the retracted state, thereby smoothly removing the coins in the accumulation space 50. It can be transported.

[3. Third embodiment]
An automated teller machine 301 (FIG. 1) according to the third embodiment is different from the automated teller machine 1 according to the first embodiment in that it includes a coin processing device 310 in place of the coin processing device 10. However, in other respects they are structured similarly. The coin processing device 310 (FIG. 2) is different from the coin processing device 10 according to the first embodiment in that it includes a replenishment collection storage 324 instead of the replenishment collection storage 24, but is similar in other respects. It is composed of

The replenishment collection warehouse 324 (FIG. 3) is different from the replenishment collection warehouse 24 according to the first embodiment in that it includes a conveyor belt section 355 in place of the conveyor belt section 55, but is otherwise similar. It is composed of

As shown in FIG. 22A, which corresponds to FIG. 6, the conveyor belt section 355 is different from the conveyor belt section 55 according to the first embodiment in that it has a guide protrusion 370 in place of the guide protrusion 70. Although they are different in some respects, they have the same structure in other respects.

The guide protrusion 370 has a protrusion 371 and a leaf spring 373 that respectively correspond to the protrusion 271 and spring 273 of the guide protrusion 270 according to the second embodiment. The protrusion 371 has a three-dimensional shape that is generally similar to a cylinder, and although its lower surface side (plate spring 373 side) is a plane substantially perpendicular to the central axis of the cylinder, its upper surface side (accumulation space 50 side) is a plane that is inclined with respect to the lower surface. Incidentally, like the protrusion 71 and the like in the first embodiment, the protrusion 371 is made of a metal material such as stainless steel.

The leaf spring 373 is an elastic metal plate-like member, and the upper surface side near its upper end is fixed to the lower surface side of the belt guide 67, and the bottom surface side of the protrusion 371 is fixed to the upper surface side near its lower end. .

With this configuration, the guide protrusion 370 allows a part of the protrusion 371 to pass through the guide hole 68H of the belt guide 67L in a natural state in which no external force is applied to the leaf spring 373, so that the vicinity of the tip of the protrusion 370 is inserted into the inclined surface 68. Protrude to the upper right side. Hereinafter, in this embodiment, this will be referred to as a protruding state. At this time, the guide protrusion 370 maintains its protruding state due to the elastic force of the leaf spring 373 even if one coin abuts against the protrusion 371.

Thereby, the guide protrusion 370 can function in the same manner as when the guide protrusion 270 is in the protruding state (FIG. 20(A)) in the second embodiment. In other words, when a coin is in a standing state leaning against the left belt guide 67L near the left end on the belt flat portion 65F, the replenishment collection storage 324 transports the coin by the running of the belt 65 and moves the coin to the protrusion. By bringing the coin into contact with the body 371, the coin can be brought out of its standing position. Then, in the replenishment collection warehouse 324, as the belt 65 runs, coins can be hooked on the belt protrusions 66 and transported smoothly.

In addition, when a relatively large external force is applied to the leaf spring 373, such as when a force equivalent to a plurality of coins is applied to the protrusion 371, the guide protrusion 370 becomes as shown in FIG. 22(B). While the plate spring 373 is elastically deformed, the protrusion 371 is moved diagonally downward to the left in a generally arc shape and is retreated to the outside of the accumulation space 50. Hereinafter, in this embodiment, this will be referred to as a save state. At this time, the guide protrusion 370 can function in the same manner as when the guide protrusion 270 is in the retracted state (FIG. 20(B)) in the second embodiment. In other words, since the replenishment and recovery warehouse 324 has the protrusion 371 of the guide protrusion 370 retracted to the outside of the accumulation space 50, the coins in the accumulation space 50 can be advanced without being obstructed.

In other respects as well, the replenishment collection warehouse 324 according to the third embodiment can have the same effects as the replenishment collection warehouse 24 according to the first embodiment and the replenishment collection warehouse 224 according to the second embodiment. .

According to the above configuration, the coin processing device 310 of the automatic teller machine 301 according to the third embodiment has a guide protrusion at a location near the lower end of the inclined surface 68 with respect to the conveyor belt portion 55 of the replenishment and collection warehouse 324. A protrusion 371 of the portion 370 is provided. Therefore, when a coin is in an upright position outside the belt protrusion 66 of the belt 65, the replenishment collection storage 324 guides the coin inward by bringing the vicinity of the tip of the protrusion 371 into contact with the coin. As a result, the replenishment collection warehouse 324 can transport the coins using the belt protrusion 66, and can effectively prevent the coins from remaining in the accumulation space 50. Furthermore, when a force equivalent to a plurality of coins is applied to the protrusion 371, the replenishment collection storage 324 moves the protrusion 371 from the protruding state to the retracted state, thereby smoothly removing the coins in the accumulation space 50. It can be transported.
