Title: Coin dispensing apparatus for circulating overflowing coins

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a coin dispensing apparatus, and more particularly, to a coin dispensing apparatus having a large bulk coin storage capacity, within a limited space, including a first coin storage bowl and a second coin storage bowl that can receiving overflowing coins which can operatively translate those coins through a coin transporter unit for re-circulating them to the first coin storage bowl. 
     2. Description of the Prior Art 
     High capacity coin hoppers have been suggested for storing, agitating and dispensing a large volume of coins or tokens in a gaming machine, such as illustrated in U.S. Pat. No. 5,190,495. A rotating coin dispensing disk is tilted to a horizontal surface and receives coins from a cylindrical mount adapter for ejecting coins from the coin hopper. A rotating cylinder is positioned between a coin bowl and the cylindrical mount adapter. Basically, the coins move through the coin hopper, the rotating cylinder, and the mounting adapter for dispensing by the rotating disk. The supply of coins depends upon a gravity feed, and as such, the coin bowl is tilted at least 30° and elevated relative to the disposition of the rotating coin disk dispenser. 
     The Japanese Laid Open Patent Publication 07/000595 discloses an overflow storage bowl which receives overflow coins from a hopper bowl, and a coin carrier device that can carry the coins from the storage bowl to the hopper bowl. A coin transporter unit is mounted within a sidewall of the hopper device for lifting the coins back to the coin hopper. 
     U.S. Pat. Nos. 4,589,433 and 5,122,094 are cited of general interest to disclose various types of hopper type coin dispensing apparatuses. 
     Increasing the coin storage capacity of a coin dispensing apparatus within the allocated space of a gaming machine remains an issue, particularly in the gaming industry, which relies on coin dispensing apparatuses and gaming machines such as slot machines, to continually pay out coins to players at high speeds. Therefore, there is still a need to maximize the coin storage capacity in this industry. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide an improved coin dispensing apparatus having a relatively large coin storage capacity by increasing the operative volumetric capacity of the limited space that is made available in a gaming machine. 
     The present invention includes a first coin storage member having a coin dispenser unit operatively connected to the first coin storage member for dispensing coins. A second coin storage member is operatively connected to the first coin storage member in such a manner to increase the overall storage capacity and is capable of receiving an overflow of coins when the first coin storage member stores a predetermined quantity of coins. A coin transporter unit is operatively mounted in the base of the second storage member to receive coins from a bottom surface of the second coin storage member and to translate them for removal from the second coin storage member. A coin guide member is operatively connected to the coin transporter unit for lifting coins from the coin transporter unit to return the coins to the first coin storage member. Appropriate sensors can monitor the storage level of coins in the first coin storage member and thereby automatically activate the coin transporter unit in the second coin storage member. 
     By optimally designing an arrangement between the first coin storage member and the configuration and shape of the second coin storage member, an increase in the storage capacity can be achieved and the previous loss of storage space beneath the first coin storage member can be utilized. The second coin storage member can basically encompass and extend beneath the first coin storage member whereby overflowing coins from the first coin storage member can fall by gravity into the second storage member. A horizontally orientated coin transporter unit can translate the coins from the bottom of the second coin storage member to a vertically orientated guide member that can lift the coins and deposit them by gravity into the first coin storage member. 
     The first coin storage member can still have a tilted disposition so that a gravity feed can direct coins to a coin dispenser unit operatively connected to the first coin storage member. The coin transporter unit mounted in the second coin storage member can be mounted underneath the first coin storage member with the coin guide member extending along a side of the second storage member for returning coins to the first coin storage member at a position above the coin dispenser unit. The arrangement of the coin transporter unit and coin guide member does not require a sloping bottom surface for the second coin storage member, and thereby maximizes the quantity of coins stored in the second coin storage member. The coin guide member can be relatively inexpensively constructed and can be integrally formed as a portion of the second coin storage member. The coin guide member can include a groove of an appropriate dimension for the coins which can be integrally formed on an outer wall surface of the second coin storage member. Alternatively, the coin guide member can be attached to an outer surface of the second coin storage member to further strengthen the construction. Preferably a drive member used for rotating the coin transporter unit is placed along one side of the second coin storage member.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventors of carrying out their invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the general principles of the present invention have been defined herein to specifically provide a coin dispensing apparatus having increased coin storage capabilities with a first coin storage member operatively positioned relative to a second overflow coin storage member so that it can re-charge the first coin storage member. 
     The present invention is designed to provide an improved coin dispensing apparatus that can dispense coins, medallions, disks, or tokens that are commonly used in the gaming industry. The present invention utilizes the terminology “coin” in a generic manner to also include not only monetary coins, but other forms of disks, tokens, and medallions that are frequently used in the gaming industry. The present invention addresses the specific confines and limitations of storage space that is allocated in a gaming machine and attempts to maximize the coin storage capacity while maintaining an economical arrangement of parts for both construction and maintenance purposes. 
     As can be appreciated, the various components and parts described in the present invention can be formed from either metal or plastic components. Additionally, a person skilled in this field can appreciate that various equivalent components can be utilized to achieve the same function and purpose of the present invention and that a control system (not shown), for example, such as a microcomputer-based system having appropriate sensors and input/output interfaces can be used to automatically drive motors for controlling the disposition of the coins. 
     A first embodiment of the present invention is shown in FIGS. 1 through 8. Referring to FIGS. 1 and 2, an upright support plate  1  is mounted on a lower base in such a manner to provide a tilt to a first coin rotating disk  2  that forms a dispensing and segregating portion of a coin dispensing unit. A first storage coin bowl  3  is mounted to include sloping surfaces  3 S 1  and  3 S 2  above the first coin rotating disk  2  with a bottom wall  3 AC sloping to direct coins by gravity feed to the rotating coin disk  2 . The support plate  1  is fixed on the frame members  6 A and  6 B of the base  5 . The support plate  1  provides a tilt relative to a horizontal support surface of about 60°. The first rotating coin disk  2  includes a circumferential disk configuration with a base place  2 A and a perimeter flange  2 B. A plurality of coin receptacle holes  2 C, for example eight in the disclosed embodiment, are formed in the base plate  2 A. An output shaft  7 A of a gear reduction assembly such as a gear speed reducer unit  7  is connected to the rotating coin disk  2  and is fastened on the back surface of the support plate  1 . The illustrated shaft line CL disclosed in FIG. 4 of the rotating coin disk  2  is approximately at a right-angle position to the support plate  1 . The rotating coin disk  2  is thereby orientated at about 30° to the horizontal surface. An electric motor  8  can drive the speed reducer unit  7  which, in turn, drives the rotating coin disk  2 . 
     When a coin is to be dispensed, it is supported on the support plate  1  after it has passed through the coin holes  2 C, while the rotating coin disk  2  rotates. A protrusion (not illustrated) is provided on the rotating coin disk  2  of the back surface. When the coin contacts an appropriate pin on the support plate  1  at a predetermined position, the coin is thereby dispensed from a coin projection aperture or mouth  9 . 
     As seen in FIGS. 1,  4  and  5 , the first coin storage member or first coin bowl includes a lower base bowl  3 A and an upper increased storage bowl portion  3 B. The base bowl  3 A is operatively connected to the first rotating coin disk  2  and has an inclined cylindrical base surface. The base bowl  3 A includes the base rim  3 AA which surrounds the first rotating coin disk  2  and an opening  3 AB that forms an upper surface sidewall. The base rim structure  3 AA is fixed to the support plate  1 . The bottom wall  3 AC is almost parallel with the axis of the shaft driving the rotating coin disk  2 . Any coins C that contact the bottom wall  3 AC will, by their weight and gravity, slide downward to interact with the first rotating coin disk  2 . A sensor electrode TB is mounted in the bottom wall  3 AC adjacent the rotating coin disk  2 . This bottom surface electrode TB is positioned to contact conductive coins, and with an upper sensor electrode TU which is fixed at a sidewall inner surface of the base bowl  3 A, constitutes a coin quantity sensor unit. When an electric current flows through the coins stacked between the electrode TB and TU, then it can be determined by a control circuit (not shown), that the coins in the first coin bowl storage member are at a level greater than a predetermined quantity of coins. As can be appreciated, the specific predetermined quantity of coins can vary over a range due to the random alignment of coins in a bulk storage configuration. When the output current is interrupted between the sensor electrodes TB and TU, a lift device shown in FIG. 3, is then operated by the control circuit. The increased bowl member  3 B also includes the first slope  3 S 1  above the rotating coin disk  2 , a second slope  3 S 2 , and a third slope  3 S 3  on the side of the rotating coin disk  2 . Generally, the storage bowl member  3 B has a funnel configuration of a pyramid shape. The upper end of the coin storage bowl  3 B provides a coin charge mouth or aperture  3 BE of a generally rectangular configuration. The lower end of the coin bowl  3 B is also of a rectangular exit configuration  3 BB and is inserted into the opening  3 AB of the base bowl  3 A. The lower end of the coin bowl  3 B is formed into a rectangular configuration which is smaller than the upper end including the exit  3 BB. The exit  3 BB of the coin bowl  3 B is inserted into the opening  3 AB of the base bowl  3 A and is fixed by screws or other appropriate fasteners to the base bowl  3 A at an upper end. An overflow mouth  3 WA is formed in the vertical wall surface of the increase bowl  3 B, which is positioned above and opposite to the first rotating coin disk  2 . Any overflow of coins stored in the first coin bowl  3  will overflow by gravity through the opening  3 WA to a second coin bowl storage unit  10 . 
     As can be seen in FIG. 1, the second coin storage member or storage bowl  10  has a rectangular configuration that encompasses a forward end of the first coin bowl  3 . The left wall panel  10 L of the second storage bowl  10  is also affixed by screws or other appropriate fasteners on the left side wall of the increase bowl  3 B. Likewise, the right wall panel  10 R is affixed by screws or appropriate fasteners to the right side wall of the increase bowl  3 B. The wall panel  10 C, which is opposite to the first rotating coin disk, is almost arranged in a vertical alignment. A cylindrical exit hole or aperture  10 E, as shown in FIG. 2, is positioned in the base plate  10 D of the second storage bowl  10 . The base plate  10 D, as shown in FIG. 4, has a slanted configuration so that the coins will slide downward to engage with the exit hole  10 E. The wall panel  10 F, as shown in FIGS. 2 and 4, contacts the bottom wall  3 AC of the base storage bowl  3 A. Therefore, the second storage bowl  10  includes at least the base bowl  3 A as part of its structure. As can be readily appreciated, the second storage area is formed between the second bowl  10 , the base bowl  3 A, and the increase bowl  3 B. A rectangular flange  10 G is formed about the circumference of the exit hole  10 E and is fixed on the upper surface of the gear box  27 . 
     A second coin rotating disk  21 , which forms a portion of a coin transporter unit, is operatively mounted to the second coin storage member or bowl to remove coins from a bottom surface of the second coin storage bowl member and to translate them for removal from the second coin storage bowl member. The second rotating coin disk  21  is placed below the exit hole  10 E of the second coin bowl  10 . The coin transporter unit  20  includes a second rotating coin disk  21  and a rotation extrusion body  23 . The second rotating disk  21  is circular and includes second coin passage holes  21 A, which in the preferred embodiment is three holes. A feed protrusion  21 B, as shown in FIG. 6, is placed between the passage holes  21 A of the second rotating coin disk  21  back surface. The second rotating coin disk is positioned in a horizontal plane and below the lowest edge of the first rotating coin disk  2  as shown in FIG. 4. A rotating shaft  22  is mounted on the gear box  27  and is connected to this second rotating coin disk  21 . The second rotating coin disk  21  is rotated at a first circular concavity  27 A formed at the upper surfaces  27 U of gear box  27  and exit hole  10 E of the second coin bowl  10 . The second rotating disk  21  is positioned at a left side wall  10 L offset from the shaft line CL of the first rotating coin disk as shown in FIG.  3 . The second coin rotating disk  21  is also placed below the coin passage mouth  3 WA of the increase bowl  3 B. 
     As shown in FIG. 6, the second rotating coin disk  21  has, adjacent to one side, a rotation extrusion body  23  of a three-prong shape having arms  23 A,  23 B, and  23 C positioned at 120° offset spaces. Rotation body  23  is affixed to a rotating shaft  24  of the gear box  27 . A second circular concavity  27 B is placed at the upper surface  27 U of the gear box  27  in a left side wall  10 L from the shaft line CL. The rotation body  23  rotates so that the tips of the protruding arms  23 A- 23 C are rotated in a horizontal plane beneath the second coin rotating disk  21 . An electric motor  26  with a speed reducing gear arrangement  25  is affixed at the upper surface in a right wall panel  10 R of the gear box  27 . The electric motor  26  is placed at an outside edge of the slope of the base plate  10 D of the second coin bowl member  10 . While the electric motor  26  is on an upper surface  27 U of the gear box  27 , its arrangement does not interfere with the position of the second coin bowl  10 . A gear  28  is affixed at the output shaft  25 A of gear box  27  beneath the speed reducer  25  shown in FIG.  8 . An idle gear  30  is fixed on a rotation counter shaft  29  mounted in the gear box  27  and engages with gear  28 . A gear  31  is affixed at the upper end of the rotating shaft  24  and engages with the gear  30 . Gear  32  is affixed at the lower end of the rotating shaft  22  and engages with gear  31 . Gears  30 - 32  are the same diameter and are rotated in synchronization. 
     A mobile roller  23  is positioned at the boundary of a depression or groove  27 D and the second circular concavity  27 B as shown in FIG.  7 . The mobile rollers  33  are freely mounted at the tip of the shaft  35  as shown in FIG.  8 . Shaft  35 , in turn, is fixed on a fluctuation lever  34  placed on the back surface side of the gear box  27 . The fluctuating lever  34  is arranged about the rotating shaft  24  and is biased by a spring  37  anchored on a pin  36  on the underside of the gear box  27  so that the fluctuation lever  34  is biased in a counter-clockwise direction. Mobile roller  33  is rotated, in FIG. 7, in a counter-clockwise direction when the fluctuation lever  34  is stopped by the stopper  38 . The space between the mobile roller  33  and a regulation piece  39 B of a first circular concavity  27 A is set at a distance less than the diameter of the coin C thereby preventing any backward movement of the coin C as it is being translated to a coin guide member. A guide disk G, as shown in FIG. 7, is fixed in the first circular concavity  27 A about the rotating shaft  22  so that it is concentrically arranged. Three feed protrusions  21 B are placed between the second coin passage hole  21 A at the same radial position from the rotating shaft  22  so that they rotate outside of the guide disk G. A rod-like regulation pin  39 A is placed in between the guide disk G and the rotation locus of the feed protrusion  21 B. The regulation pin  39 A is affixed on the gear box  27  outside of the feed protrusion  21 B rotation locus. The regulation piece  39 B includes a linear guide plane  39 BS which is almost parallel to form a tangent between the first circular concavity  27 A and the second circular concavity  27 B. A second induction plane  27 D 2  of derivation groove  27 D is formed in the extension of the guide plane  39 BS of the upper surfaces  27 U of the gear box  27 . 
     The coin guide member  40 , which provides a passageway for the coins, is shown in FIGS. 6 and 7 and includes an arc division  41 , a straight division section  42 , an arc guide  44 , a straight guide  45 , and an induction guide  46 . The arc division  41  includes an arc plane  43  with a one quarter circumferential length. The straight division  42  continues the arc division  41  and is mounted above it. An overlapping arc guide  44  is bent in a complimentary configuration to capture the coins being translated up the arc guide  44 . A straight guide portion also captures the coins when mounted on the straight division  42 . The rectangular slab-shaped guide  46  guides the coins back to the first storage bowl  3 . The arc division member  41  is affixed at the upper surface  27 U of the gear box  27 . As can be appreciated, the groove  41 G is slightly smaller than the diameter of the coin, so that the coin will slide along the rims  41 L and  41 R. An outer rim  41 R 2  and  41 L 2  can interface with the arc division guide  44 . Appropriate fasteners can be utilized to fasten the structure together. The lower end of the arc division  41  is arranged adjacent to the groove  27 E formed on the upper surface  27 U of the gear box  27 . The upper surface of the rims  41 R and  41 L are located in the extension of a plane of the groove  27 D. 
     Openings  44 A are provided in the arc guide  44  in order to monitor coin movement, while a stiffening bracket  44 B extends across the arc guide  44 . The upper vertical straight division  42  has spacers  42 L and  42 R which interface with the straight guide  45 . As can be appreciated, a coin is directed through the straight groove  43 D to the curve passageway  43 P to direct the coins to a rectangular tubular guide  46  that protrudes on the left side. The tip of the guide  46  tilts to the increased storage bowl  3 B. The guide  46  is inserted into a coin storage mouth  47  of the sidewall  3 BR of increase storage bowl  3 B. This coin supply mouth is placed above the lower end of the first coin rotating disk  2  so that it can supply the re-circulated overflow coins to the base coin bowl  3 A. Base  5  and gear box  27  are fixed and united on the plane substrate  49 . 
     In operation, the first embodiment of the present invention has bulk coins C supplied until the upper electrode sensor TU is contacted. At that point, a predetermined quantity of coins is contained within the second storage compartment  11  of the second coin bowl  10 . As additional coins are inserted during the play of the game, they are introduced into the coin charge mouth  3 BE to the first coin storage bowl  3 . Overflow coins C will thereby flow from the coin mouth  3 WA to the second coin bowl  10 . 
     When coins are to be dispensed, the first coin rotating disk  2  is activated by energizing the electric motor  8  so that it is rotated through the speed reducer unit  7 . A coin C will fall within the coin holder  2 C by the rotation of the first coin rotating disk  2 . The coin is then subsequently dispensed from the aperture  9 . Other coins C will slide down the bottom wall  3 AC to the first coin rotating disk  2  until such a point that the electric current will not flow between the upper sensor electrode TU and the bottom sensor electrode TB. At this time, it can be determined that the quantity of coins C remaining in the base storage bowl  3 A is lower than a predetermined number. At this point, a control circuit (not shown) will then be activated to energize motor  26  to thereby rotate the second rotating disk  21  in a counter-clockwise direction through the speed reducer  25 , the output shaft  25 A, and the respective gears  28 - 32 . The rotation extrusion body  23  is synchronized with the second coin rotating disk  21  and is rotated in a clockwise direction. As a result of the rotation of the second coin rotating disk  21 , coins are stirred and are caused to fall into the second coin passage hole  21 A when the coins become parallel to the second rotating coin disk  21 . The coin C is supported in the basal plane of the first circular concavity  27 A and is guided in the guide disk G so that the feed protrusion  21 B of the back surface of the second rotating disk  21  pushes it forward. 
     The coin C will be stopped at the regulation pin  39 A when the feed protrusion  21 B pushes it to that point and then the feed protrusion  21 B will push the coin out to the groove  27 D. The coin C will contact the guide plane  39 BS of the regulation piece  39 B. At this point, the coin C will be temporarily positioned as shown in FIG. 7 until arm  23 A will push the coin C forward to be guided by the guide plane  39 BS and the second guide plane  27 D 2  whereby it is pushed into the groove  27 D. The coin C will act against the bias force of the spring  37  to push the mobile roller  33  to the right side direction. Afterwards, the mobile roller  33  pushes the coin C out to the groove  27 D. The coin C is captured at the upper part of the groove  27 D and the lower end division of the arc guide  44 . After the initial coin C passes, the fluctuation lever  34  is rotated by spring  37  and is stopped by the stopper  38  to remain in a standby condition. In this standby condition, the coin C is stopped by mobile roller  33  if coin C attempts to return to rotating coin disk  21 . The distribution of the coins C will continue as the second coin rotating disk  21  rotates. The successive coins will push the preceding coins up the passive coin guide member  40  until the coins are ultimately dispensed back into the first storage coin bowl  3 . The electric motor  26  will continue to operate to re-charge the overflowed coins back into the coin storage bowl  3  until the upper sensor electrode TU and the lower sensor electrode TB are again electrically interconnected through the accumulation of stored bulk coins. 
     By this particular arrangement, it is possible to re-direct the coins discharged from the second coin bowl from initially a horizontal arrangement to a vertical orientation through the coin guide member  40  in a relatively limited space. As can be appreciated, the coin guide member  40  is initially arranged in a horizontal position and below the lower end of the first coin rotating disk  2 . This increases the storage space of the second storage bowl  10  whereby the quantity of the coins that can be utilized in this limited space is significantly increased. 
     Additionally, by connecting the coin guide member  40  at the right wall panel  10 R of the second coin storage bowl  10 , the right wall panel  10 R is further reinforced. 
     As a modification to this first embodiment, the first coin bowl  3  can be composed of only the base bowl  3 A. In such an arrangement, guide boards can be utilized to dispense the coin C from the straight passage  43 D to fall into the opening  3 AB of the base coin bowl  3 A. Additionally, the rotation extrusion body  23  may be deleted, and accordingly, the feed protrusion  21 B of the second coin rotating disk will push the coins C into the groove  27 D. In such an arrangement, the coin transporting unit  20  includes the second rotating coin disk  21  which is operatively connected to the coin guide member. Additionally, the second coin rotating disk  21  can be of a type which dispenses coin C one by one by pins which are affixed to the surface of a rotating disk in a predetermined space. The coin quantity sensor can also be modified to use a light sensor whereupon the vertical buildup of the bulk coins can prevent the emitted light from a light emitter from reaching a photo receptor thereby activating a sensor signal for the control circuit. 
     A second embodiment of the present invention can be understood by reference to FIGS. 9-12. In this embodiment, the first coin storage bowl  3  is only the base bowl  3 A and the structure of the coin guide member  40  is altered. A second coin bowl  51  represents a combination between the first coin bowl piece  51 A and a second bowl piece  51 B. The first coin bowl piece  51 A includes a tip sidewall  51 AS including left and right L-shaped sideboards  51 A and  51 AR. The first bowl piece  51 A further includes a ramp  51 S 1  extending from the sidewall  51 AS and a second interconnecting ramp  51 S 2  with a lower straight board  51 S 3  as seen in FIG.  12 . The first coin bowl piece  51 A includes a first circular concavity  27 A and a second circular concavity  27 B, an arc concavity  52 A, straight groove  53 D, and guide groove  54  of the base plate  51 A. The arc concavity  52 A constitutes an arc division  52 . The respective straight groove  53 D and groove  54  of the straight division  53  are formed as indentations in the inner surface of the right side board  51 AR. 
     In arc division  52 , the first and second stage divisions are equal to the first embodiment so that an arc groove  52 G is formed for permitting the passage of coins. A relatively straight passageway  53 D extends upward from the continuation of the arc groove  52 G and interconnects with the groove  54  to permit coins to fall onto the second ramp  51 S 2  side. At the second ramp  51 S 2  and the straight board  51 S 3 , a semi-circular opening  51 W is formed so that the base coin bowl  3 A may fit into it. Therefore, the first coin bowl  3  is the base bowl  3 A. An electric motor  26  with a speed reducing gear arrangement  25  is affixed at the base plate  51 AB on the right side board  51 AR. The gears (shown in FIG. 8) are also included in the back surface side of the base plate  51 AB. A second bowl piece  51 B has a rectangular configuration and includes a left side board  51 BL and the right side board  51 BR, an episternum  51 BF and a base plate  51 BB. The episternum  51 BF connects between the left side board  51 BL and the right side board  51 BR. 
     A circular exit hole  10 E is formed at the base plate  51 BB and the base plate  51 BB has slopes which approach from the lower end of the side plate  51 BL,  51 BR, and  51 BF to the exit hole  10 E. As can be appreciated, a coin C will slide down the base plate  51 BB. An arc convex division  51 B is opposite to the arc concavity  52 A to form a curving coin passage groove on the underside of the base plate  51 BB. The surfaces  51 BS cover the straight groove  53 D and groove  54  to provide a straight passageway  43 P and groove  51 P. A rectangular oblique notch  55  is formed at the right side board  51 BR under the groove  54 , which is opposite to a second ramp  51 S 2 . Wall surface  54 B of the groove  54  tilts downward to the second coin bowl  51  and is opposite to the coin supply mouth  56 . The guide plate  51 BG is affixed to the inner surface of the right side board  51 BR below the coin supply mouth  56 . 
     Mounting flange  51 BH is formed in the circumference of the exit hole  10 E. Referring to FIG. 12, the combination between the first compass bowl piece  51 A and the second compass piece  51 B is illustrated. The first bowl piece  51 A is combined so that the base bowl  3 A may protrude into the second bowl  51  from the opening  51 W. In this arrangement, the first bowl piece  51 A is affixed to the substrate  49 . 
     The first coin rotating disk  2  is placed below the first ramp  51 S 1  and the second ramp  51 S 2 . The second bowl piece  51 B fits into the inside of the first bowl piece  51 A so that the external surface of the left side board  51 BL of the second bowl piece  51 B contacts the inner surface of the left side board  51 AL of the first bowl piece  51 A. The external surface of the right side board  51 BR contacts along the inner surface of the left side board  51 AR. Flange  51 BH is affixed onto base plate  51 AB and the second coin storage bowl  51  is thereby constructed. The second coin storage bowl  51  includes the base bowl  3 A which is the first coin storage bowl  3 . The arc coin passageway  41 P is constructed of the arc convex division  52 B of the second bowl piece  51 B covering the arc concavity  52 A. The straight coin passageway  43 P and passage  51 P are constructed by the external surface  51 B as to the right side board  51 BR that cover the straight groove  53 D and grooves  54 . The tip of the guide plate  51 BG is located above the opening  3 AB of the base bowl  3 A. 
     As with the first embodiment, the coin rotating disk  21  and the rotation extrusion body  23  will push the coins C up the arc passageways  41 P. The coins, when they are pushed through the passage way  51 P, will fall into the inclination side stage division  54 C. In turn, the coin C will fall onto the wall surface  54 B by the pull of gravity and will slide on the wall surface until it reaches the coin supply mouth  56  and falls into the guide plate  51 BG. As can be appreciated, the coin guide passageway is constructed by using the coin bowls&#39; wall surface thereby simplifying the structure and increasing the utilization of the narrow space that is available. The coin passageway  51 P, which is connected to the coin supply mouth  56 , is a coin passageway which tilts above, thereby coin C will not block the supply mouth  56  because it does not flow into the coin passageway  51 P. 
     Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiments can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
