From this point of view, it can be said that the hopper type coin payout device is excellent in versatility and convenience.

  Hereinafter, the specific configuration of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 33 are used both as a large coin (Cl) having a diameter of 26.5 mm and a small coin (Cs) having a diameter of 20 mm. The two types of hopper-type coin payout devices that can be normally paid out are illustrated as follows: (1) is a mounting base integrated with a frame from a metal plate, and a rectangular metal base plate (2) on the opening surface thereof However, it is attached and fixed in a covered state from above. (3) is fixing screws at the four corners.

  In the case of the illustrated example, the base plate (2) attached and fixed to the opening surface of the mounting base (1) is in an inclined state of a certain angle (α), but there may be a specification that is attached and fixed in its horizontal state. In any case, a reversible motor (4) for rotating the disk rotor is attached to and integrated with the back surface of the base plate (2) via a plurality of fixing screws (not shown).

  The reversible motor (4) is rotated forward in one direction (counterclockwise) (F) in FIGS. 28 and 31, but a sensor (not shown) causes a phenomenon of biting or clogging coins (Cl) (Cs). When detected, the control board (not shown) receiving the detection output signal from the sensor is rotated backward (R) in the other direction (clockwise) as shown in FIGS. 30 and 33 to eliminate the abnormal phenomenon. Can be done.

  (5) is an output shaft of the reversible motor (4), and at the tip end that penetrates the base plate (2), a disk-carrying disk rotor (D) is detachable and replaceable from above, and It is attached so that it can rotate integrally. The perforated disk rotor (D) is integrally molded as shown in FIGS. 10 and 11 from a high-strength synthetic resin such as polyacetal resin (preferably trade name: Duracon).

  That is, in FIGS. 10 and 11 extracted and shown, (6) is a disc rotor main body having a constant thickness, and the center portion of the disc rotor body falls over the coin (Cl) (Cs) to the peripheral portion. As the guide convex (7), it stands upright and the disk rotor main body (6) has a peripheral edge portion corresponding to a constant thickness of the coin (Cl) (Cs) as a coin receiving wall (8). It is bordered in a standing upright position by the height to be.

Openings are formed in an overall radial symmetrical distribution type that maintains D (Pitch Circle Diameter). Each coin receiving hole (9) is slightly larger than the large-diameter coin (Cl), and its opening edge serves as a conical receiving surface and is chamfered so as to easily receive the coin (Cl) (Cs).

  (10) is a plurality of conical stirring protrusions projecting from the surface of the disk rotor body (6) as a positional relationship between adjacent coin receiving holes (9), and (11) is a coin As a positional relationship interposed between adjacent ones of the receiving holes (9), a plurality of protrusions are provided so as to protrude from the back surface of the disc rotor body (6) by a height substantially corresponding to a certain thickness of the coin (Cl) (Cs). (4 in total in the illustrated example) are rear curved wings, which push and convey coins (Cl) (Cs) as the perforated disk rotor (D) rotates.

  That is, the back surface left as a depressed state in the peripheral portion of the disc rotor body (6), as opposed to the backward projection of the rear curved blade (11), and the flat surface of the base plate (2) Are defined so as to function as a coin conveyance path (G) substantially corresponding to a certain thickness of coins (Cl) (Cs).

  Each of the rear bent blades (11) has a relatively small radius of curvature along the opening edge of each coin receiving hole (9) in relation to the forward rotation direction (F) of the perforated disk rotor (D). The disk rotor has a so-called tapered arc shape with a concave curved surface (12r) on the rear side and a convex curved surface (12f) having a relatively large radius of curvature that does not follow the opening edge of each coin receiving hole (9). The main body (6) extends from the center to the peripheral edge by a certain length.

  In the normal state where the perforated disk rotor (D) rotates forward in one direction (counterclockwise direction) (F) in FIGS. 28 and 31, coins (Cl) (Cs) are inserted by the convex curved surface (12f) on the front side. In the abnormal state where the perforated disk rotor (D) rotates backward in the other direction (clockwise direction) (R) in FIGS. 30 and 33 while the paper is pushed forward and conveyed, the coin (Cl) ( Cs) will be pushed forward.

  Moreover, in the middle part of each of the rear curved wings (11) extending as a tapered arc having a certain length from the center portion to the peripheral portion of the disc rotor body (6), a relief groove for a coin payout derivative described later is provided. (13) is cut out as a whole so as to draw a circle trajectory as shown in FIG. 11, whereby each of the rear bent wings (11) has a root side (center side) blade piece (11a) and a tip side. It is divided into two parts (peripheral side) and a blade piece (11b).

  In the case of the illustrated example, the above-mentioned coin payout derivative relief grooves (13) are notched in the middle part of each of the rear curved blades (11) in the disk rotor body (6) as two rows of the entire concentric circle locus. However, depending on the diameter of the coin (Cl) (Cs) to be handled or the number of paid-out derivatives thereof, the relief groove (13) may be cut out as a circle locus of one row or three or more rows.

  The perforated disk rotor (D) in the illustrated example is a synthetic resin product, and each of the rear curved blades (11) extends in a tapered arc shape. Further, the divided root side blade piece (11a) and the tip side blades are divided. The piece (11b) is shaped like a backward U-shaped rib when viewed from the back side as shown in FIG. 11, and the perforated disk rotor (D) is used as a metal product and each of the rear curved blades ( 11) may extend as a tapered arc from the center of the disk rotor body (6) toward the peripheral edge.

  Similarly, a coin outlet (17) having a constant opening width (W1) as shown in FIGS. 5, 12, and 13 is cut out on one side surface of the mounting flange (15). On the downstream side in the traveling direction (F) in which D) rotates forward, a separate roller escape port (17a), which will be described later, is partially cut away to the barrel (14). In the case of the illustrated example, the coin outlet (17) of the coin receiving hopper (H) is opened upward in the inclined base plate (2).

  On the other hand, a total of four locking pins (18) corresponding to the key holes (16) of the mounting flange (15) are planted in the base plate (2). By inserting the key hole (16) of the mounting flange (15) so that the key hole (16) can be freely inserted and removed from above, and rotating in one direction, the coin receiving hopper (H) is mounted on the surface of the base plate (2). It can be attached and fixed, and can be removed from the base plate (2) by turning in the opposite direction.

  In the attached state, as is apparent from FIG. 3, the peripheral portion of the perforated disc rotor (D) is surrounded by the barrel (14) of the coin receiving hopper (H). However, only the coin outlet (17) cut out in the mounting flange (15) of the coin receiving hopper (H) is in an open state communicating with the coin conveying path (G) of the perforated disk rotor (D). To be kept.

  (M) is a relationship facing the coin outlet (17) of the coin storage hopper (H) from above to one side surface corresponding to the base plate (2) (in the illustrated example, the upper side surface in an inclined installation state). This is a sensor cradle attached and fixed in a covering state that keeps a fixed gap with the flat surface of the base plate (2) by a fixing screw (19), and is composed of a single metal plate.

  As shown in FIGS. 2 to 4, the center portion of the sensor cradle (M) has a pair of oppositely bent pieces (20) and a base plate (2) to guide the coins of the coin receiving hopper (H). A section is formed as a tunnel-type coin payout passage (21) that faces the exit (17) and passes directly therethrough. (22) is an escape slit for the two back-facing folded pieces (20), and is cut out in the base plate (2).

  Reference numeral (23) denotes a coin count sensor installed and fixed to the sensor cradle (M) in a mounted state. The coin count sensor is composed of a transmissive (or reflective) photo interrupter and is paid out from the coin payout passage (21). The coin (Cl) (Cs) in the process is detected. (24) is a light transmission hole formed corresponding to the base plate (2).

  Reference numeral (25) denotes a pair of coin payout derivative sinking holes distributed in an elliptical shape that penetrates the base plate (2) in the inside surrounded by the barrel (14) of the coin receiving hopper (H). As suggested from FIGS. 28 to 33, on the entire concentric circle trajectory of the coin payout derivative escape groove (13) obtained by dividing the rear curved blade (11) of the perforated disk rotor (D). In parallel.

  (A) is a coin (Cl) (Cs) which is pushed forward along the coin transport path (G) by the perforated disk rotor (D) which rotates forward in one direction (counterclockwise) (F). In order to change the direction from the coin transport path (G) to the coin outlet (17) and the coin payout passage (21) of the coin receiving hopper (H). It is a payout derivative.

  Furthermore, the coin payout derivative (A) is a pseudo-Y-shaped type having a base-side mounting seat (26) and a tip-side bifurcated fork piece (27) as shown in FIGS. The base plate (2) is made of a rigid stainless steel plate cut out in a contour shape, and a base fixing seat (26) whose base seat (26) hangs downward from the base plate (2) integrally. It is attached to the back side in a cantilevered state. (29) is a fixed screw receiving hole of the mounting seat (26).

  Further, (30) is a spring pressure adjusting nut screwed and fastened in the middle of the fixing screw (28), and a compression coil spring (31) interposed between the upper and lower sides of this and the coin payout derivative (A). Is wound around the fixing screw (28), and thereby the coin payout derivative (A) itself is pressed against the back surface of the base plate (2) and pressed.

  On the other hand, a pair of cylindrical coin receiving pins (32) that work during forward rotation of the perforated disk rotor (D) are caulked and integrated into the front-side planted state on the bifurcated fork piece (27) on the tip side. Has been. The coin receiving pins (32) are fixed to the thickness of the coin (Cl) (Cs) from the surface of the base plate (2) through the retracting hole (25) of the base plate (2) by the biasing force of the compression coil spring (31). 18, coins (Cl) (Cs) that are pushed forward in one direction (counterclockwise) (F) by the positive rotation of the perforated disk rotor (D) are shown in FIG. As described above, once received from the downstream side by the circular arc surface, the direction is properly changed from the coin transfer path (G) to the coin outlet (17) and the coin payout path (21) of the coin receiving hopper (H). To induce.

  Further, a pair of coin escape guiding pieces (33) that work when the perforated disc rotor (D) rotates in the reverse direction from the bifurcated fork piece (27) on the front end side is also the arc back surface of the coin receiving pin (32). As the upright state corresponding to the position, the surface is bent upward and integrally, and the bent upper surface (the cut edge of the stainless steel plate) is a smooth climbing slope surface toward the apex of the coin receiving pin (32). Modeled as (33a). Both the coin escape guide pieces (33) are also in a biased state in which they always protrude face-up from the intrusion hole (25) of the base plate (2).

  Then, coins (Cl) (Cs) pushed forward in the other direction (clockwise) (R) by the reverse rotation of the perforated disk rotor (D), as shown in FIG. ), And the coin (Cl) (Cs) can overcome the coin receiving pin (32) and return to the normal upstream side. At the moment of overcoming, the coin escape guide piece (33) of the coin payout derivative (A) and the coin receiving pin (32) resist the urging force of the compression coil spring (31), while the protrusion / recess hole of the base plate (2) (25) will be immersed together.

  (34) is a steady-state pin that is suspended downward from the base plate (2) in a penetrating state as shown in FIGS. 7 and 8 inside the bifurcated fork piece (27). (A) Prevents itself from swinging around the fulcrum of the fixing screw (28), and inserts the coin receiving pin (32) and the coin escape guide piece (33) on the tip side into the protrusion and recess hole (25) of the base plate (2). In contrast, it is regulated so that it can properly appear and go up and down.

  In order to omit the installation of the steady-state pin (34) and the compression coil spring (31), the coin payout derivative (A) is cut out from a spring steel plate instead of a rigid stainless steel plate, and the base side thereof is cut. The mounting seat (26) is attached and fixed to the back surface of the base plate (2) by a plurality of short fixing screws (28), and the remaining forked side of the fork piece (27) can be freely deformed. The coin receiving pin (32) and the coin escape guide piece (33) may be vertically upright and integrated. Needless to say, the number of the coin payout derivative (A) and its opening / closing hole (25) is the number corresponding to the coin payout derivative escape groove (13) of the perforated disk rotor (D).

  (35) and (36) are coin payout passages (21) formed by the coin outlet (17) cut out in the mounting flange (15) of the coin receiving hopper (H) and the sensor cradle (M). And a coin payout roller and a separate roller interposed in a parallel state as shown in FIG. 3 and FIGS. 28 to 33, and a traveling direction (F) in which the perforated disk rotor (D) rotates in the forward direction. Therefore, the pair of a coin payout roller (35) facing the upstream side and a separate roller (36) facing the downstream side makes the entrance portion of the coin payout passage (21) the small diameter coin (Cs). The opening width (W2) is slightly narrower than the diameter.

  Moreover, the separate roller (36) is taller on the downstream side of the coin outlet (17) than the coin payout roller (35) is away from the coin outlet (17) of the coin receiving hopper (H). Through the cut-out escape port (17a), it is at a position as close as possible so as not to interfere with the peripheral edge of the perforated disk rotor (D). As described above, the coin payout derivative (A) is located on the downstream side in the traveling direction (F) in which the perforated disk rotor (D) is rotated in the same manner as the separate roller (36). is there.

  (37) is a fulcrum shaft that hangs downward and integrally from the base plate (2), and a base portion of a coin payout arm (38) made of a metal plate of a fixed length is pivotally attached to the shaft. On the other hand, the coin payout roller (35) is inserted into the roller shaft (39) standing upright from the front end portion of the payout arm (38) so as to be freely rotatable. Similarly, (40) is a spring receiving piece bent back from the tip of the payout arm (38).

  Further, (41) is a pedestal of a metal plate, and as is apparent from FIGS. 7 and 8, at the two points of the fulcrum shaft (37) penetrating the intermediate portion and the fixing screw (42) at one end. The base plate (2) is attached and fixed to the back surface. (43) is an arc-shaped adjustment slot cut out at one end of the pedestal (41) in order to allow the fixing screw (42) to escape, and the mounting position with the fulcrum shaft (37) as the center of rotation. Used for adjustment of

  And between the opposing spring receiving pieces (44) bent from the other end of the base (41) and the corresponding spring receiving pieces (40) of the coin payout arm (38), A tension coil spring (45) having a relatively weak tension is connected. Reference numeral (46) is a stopper stopper piece of the coin biasing arm (38) that is tensioned and biased backward from the vicinity of the other end of the pedestal (41). ) Is inserted and fixed.

  At the position where the coin payout arm (38) is received by the stopper piece (46) of the pedestal (41) by the urging force of the tension coil spring (45), as shown in FIGS. The inlet portion of the coin payout passage (21) is slightly smaller than the diameter of the small coin (Cs) due to the upstream coin payout roller (35) pivotally supported by the portion and the downstream separate roller (36). The narrow opening width (W2) is maintained. Therefore, when the coin (Cl) (Cs) passes therethrough, the coin payout arm (38) resists the urging force of the tension coil spring (45), and the fulcrum shaft The arc moves around (37), and the coin (Cl) (Cs) is taken by itself, coupled with the urging force of the coil spring (45) and the loosening action of the coin payout roller (35) itself. So that the payout at the time. Reference numeral (48) denotes an escape arc long hole for the coin payout roller (35), which is cut out in the base plate (2).

On the other hand, (49) is a separate arm made of a metal plate of a certain length, and as is apparent from FIGS. 20 to 27 extracted and shown, a circular washer receiving burr hole (50 ) Is opened. Reference numeral (51) denotes a fulcrum screw that pivotally attaches the separate arm (49) to the back surface of the base plate (2). The countersunk head (51a) of the fulcrum screw (51) and the separate arm (49) A washer (52) having a cylindrical boss (52a) that is loosely fitted to the fool hole (50) is inserted between the upper and lower sides of the upper and lower sides. (52b) is a conical saucer surface for alignment of the washer (52).

  Therefore, when the separate arm (49) performs a seesaw motion around the fulcrum screw (51), it is freely displaced in all directions of 360 degrees so as to be eccentric from the fulcrum screw (51). The boss (52a) of the washer (52) for receiving the fulcrum screw (51) has a circular shape slightly smaller in diameter than the flaw hole (50) of the separate arm (49), and more than the plate thickness of the separate arm (49). Is slightly raised. (E) shows the eccentricity (clearance) of the separate arm (49).

  The separate roller (36) is slidably fitted into a roller shaft (53) that stands up together from one end of such a separate arm (49) so as to freely rotate, and a coin payout roller (35 ) In parallel.

  Similarly, (54) is a spring receiving piece bent backward from one end of the separate arm (49), and the spring receiving piece (54) and the fixing screw (28) of the coin payout derivative (A) face each other. A tension coil spring (55) having a relatively strong tension is connected between them. Reference numeral (56) denotes a stopper piece for receiving the other end of the tension-biased separate arm (49), which is cut back from the base plate (2).

  At the position where the other end of the separate arm (49) is received by the stopper piece (56) of the base plate (2) by the tension coil spring (55), as shown in FIG. 3 and FIGS. The separation roller (36) pivotally supported by the portion passes through the separation roller escape port (17a) positioned corresponding to the downstream side of the coin outlet (17) in the coin receiving hopper (H) to provide a perforated disk rotor. It is in the state which approached the peripheral part of (D).

  In the unlikely event that a later-described biting phenomenon or clogging phenomenon of coins (Cl) (Cs) occurs, the separation roller (36) moves the boss (52a) of the washer (52) and its fool hole ( 50), the seesaw motion is performed outwardly in a state of being offset by a fixed amount (E) around the fulcrum screw (51), and the tension coil spring (55 ) And the free-rolling action of the separate roller (36) itself, the above-mentioned abnormal phenomenon can be resolved instantly. (57) is a long hole for escape of the separate roller (36), which is notched in the base plate (2).

  The coin outlet (17) having a constant opening width (W1) is notched in the mounting flange (15) of the coin receiving hopper (H), and the direction in which the perforated disc rotor (D) rotates forward. In relation to (F), a parallel pair of a coin payout roller (35) facing the upstream side and a separate roller (36) facing the downstream side forms a coin outlet (17) and a coin payout passage (21). As described above, the entrance portion of the coin payout passage (21) is maintained in the opening width (W2) narrower than the diameter of the small coin (Cs) by interposing between the two facing each other. The upstream opening edge of the coin outlet (17) is continuous with the inner peripheral surface of the circular cylinder (14) of the coin receiving hopper (H) as a coin guide wall (58) that satisfies the following various requirements. It is shaped to.

  That is, it is pushed forward from the coin conveying path (G) to the coin payout path (21) by the rear curved blade (11) of the perforated disk rotor (D) that rotates forward in one direction (counterclockwise) (F). The small diameter coin (Cs) in the process has a coin payout roller (35) and a second contact point (P2) at the convex curved surface (12f) and the first contact point (P1) of the rear curved blade (11) as shown in FIG. , When it is assumed that the upstream opening edge of the coin outlet (17) and the third contact (P3) are in contact with each other, a virtual straight line (Z−) connecting the first and second contacts (P1) and (P2). The position of the third contact (P3) is determined so that Z) is always biased outward from the center (O) of the small-diameter coin (Cs) by a certain distance (L1). This is the first requirement.

  Next, the small-diameter coin in the process of being pushed forward to the upstream side of the coin outlet (17) by the rear curved blade (11) of the perforated disk rotor (D) that rotates in the opposite direction (clockwise) (R). (Cs) at the concave curved surface (12r) and the first contact (P1) of the rear curved blade (11) as shown in FIG. 30, the coin payout roller (35) and the coin contact outlet at the second contact (P2). Assuming that the upstream opening edge of (17) and the third contact (P3) are in contact with each other, the rotation circle locus drawn by the first contact (P1) is the center (O) of the small-diameter coin (Cs). Instead, the position of the third contact (P3) is determined so as to be biased outward by a certain distance (L2). This is the second requirement.

  Furthermore, the opening width (W3) between the third contact (P3) forming the upstream opening edge in the coin outlet (17) and the separating roller (36) located downstream is necessarily large. The position of the third contact (P3) is determined so as to be larger than the diameter of the coin (Cl). This is the third requirement.

  A smooth concave curve from the third contact point (P3) positioned in this way to the outer peripheral surface of the cylinder (14) in the coin receiving hopper (H) is defined as the coin outlet (17 ) Is formed as the upstream coin guiding wall (58). However, as long as it becomes the coin guide wall surface (58) satisfying such first to third requirements, it is shaped from a straight line as shown by a chain line in FIG. No problem.

  12 and 13, the coin outlet (17) having a constant opening width (W1) shaped with the upstream opening edge as a coin guiding wall (58) is attached to the synthetic resin coin receiving hopper (H). Although notched in the flange (15), as shown in the modified embodiment of FIG. 14 corresponding to FIG. 12, the metal liner plate (between the upper and lower sides of the mounting flange (15) and the base plate (2) ( 59), the coin outlet (17) provided with the coin guide wall surface (58) may be cut out.

  According to the above configuration, the small-diameter coin (Cs) that is in contact with the first to third contacts (P1), (P2), and (P3) in FIG. As shown by the advancing chain line in the figure, the coin is passed through the mutual gap between the upstream coin payout roller (35) and the downstream coin payout derivative (A) by the front convex curved surface (12f) of the wing (11). Combined with the turning action of the payout derivative (A), it can be guided from the coin outlet (17) of the coin receiving hopper (H) to the coin payout passage (21) and can be smoothly paid out by itself.

  During the progress of the small-diameter coin (Cs), only the coin payout roller (35) receiving the weak tension of the tension coil spring (45) is arced along the arc long hole (48) of the base plate (2). It moves and the opening width (W2) of the entrance part in the coin payout passage (21) is instantly expanded.

  In FIG. 29, the small-diameter coin (Cs) rides on the coin payout derivative (A), and the center (O) of the coin (Cs) is the center of the curvature radius (12f) of the convex curved surface (12f) of the rear curved blade (11). X) and the separation roller (36) and the perforated disk rotor (D), while accidentally positioned on a thought line (LL) connecting the support point (Y) of the separate roller (36). In the meantime, the case where it is bitten in a tension state is assumed.

  When such a biting phenomenon occurs, the separate arm (49) of the separate roller (36) that receives a strong tension from the coin (Cs) is shown in FIGS. Since the center roller is displaced so as to be eccentric around the fulcrum screw (51) and the separate roller (36) retreats outwardly, the biting phenomenon can be surely eliminated by itself. it can.

  In that case, based on the output signal from the sensor (not shown) that detects the biting phenomenon, the perforated disk rotor (D) is rotated in the reverse direction (clockwise) (R) by the reversible motor (4). In this case as well, as is clear from FIG. 30, the coin receiving hopper is formed by the rear concave curved surface (12r) of the rear curved blade (11) in the disk rotor (D) with the small diameter coin (Cs). The coin can be smoothly scraped and returned from the coin outlet (17) of (H) to the coin transport path (G) of the disk rotor (D). It is possible to prepare for the push-out action.

  Since the first and second requirements for forming the coin guide wall surface (58) of the coin receiving hopper (H) are set so as to satisfy the relationship with the small-diameter coin (Cs), the large-diameter coin (Cl) As is obvious from FIGS. 31 to 33 corresponding to FIGS. 28 to 30, the large diameter coin (Cl) is moved forward with the perforated disk rotor (D). In any of the reverse rotation in which the biting phenomenon occurs, the payout action can be correctly performed by itself in the same manner as the small-diameter coin (Cs).

  In other words, the hopper type coin payout device of the present invention is based on the configuration of the coin guide wall surface (58) in the above-described coin receiving hopper (H), and uses two types of coins (small coin (Cs) and large coin (Cl)). The coin payout roller (35), separate roller (36), coin receiving hopper (H), perforated disk rotor (D), etc. can be used for coins (Cl) (Cs). There is no need to replace it according to changes in diameter, or to adjust its mounting position, and it is excellent in versatility and convenience.

  In the illustrated embodiment, a small diameter coin (Cs) having a diameter of 20 mm and a large diameter coin (Cl) having a diameter of 26.5 mm are illustrated, and two kinds of coins having a diameter difference of this degree ( Cl) (Cs) can be used as it is without needing to replace even the perforated disk rotor (D). However, if the difference in diameter becomes larger than the above, it is perforated. It is only necessary to replace the disk rotor (D) with one in which the coin receiving holes (9) corresponding to the diameter of the coin are distributed.

  The first and second requirements for modeling the coin guiding wall surface (58) of the coin receiving hopper (H) are set in relation to the minimum coin (Cs). Similarly, the third requirement is the maximum coin (Cl). Thus, for example, two or more types of coins having a diameter of 20 mm to 32 mm can be operated without any problem.

  Further, when the biting phenomenon occurs, the small diameter coin (Cs) contacts the large curved coin (Cs) with respect to the convex curved surface (12f) of the rear curved blade (11) in the perforated disk rotor (D). Unlike the contact of Cl), the contact changes completely according to the diameter of the coin, but the separate arm (49) of the separate roller (36) has a circular hole (50) and the washer (52). ) In the 360-degree cylindrical boss (52a), it is designed to deviate in all directions of 360 degrees, so that the biting phenomenon is always resolved automatically regardless of the coin diameter change. It can be done.
