  However, in the conventional technique disclosed in Patent Document 1 described above, when a gaming machine that has already been installed is replaced with another model later on the gaming machine island, the replacement work is performed regardless of the form of the gaming machine island. Was cumbersome, time consuming and cumbersome.

  The present invention was made paying attention to the problems of the conventional technology as described above, and not only can the installation work be easily performed when installing the gaming machine on the gaming machine island, It is an object of the present invention to provide a gaming machine installation frame that can be very easily exchanged when an installed gaming machine is later replaced with another model.

The gist of the present invention for achieving the above-described object resides in the following invention.
In the gaming machine installation frame (300, 300A) for installing the gaming machine (10, 10A),
An outer frame case (310) attached to the installation location (4a) on the gaming machine island (4) and having at least the front side opened;
An inner frame case (320, 320A) which is detachably attached to the inside from the opening of the outer frame case (310), at least the front side is opened, and the gaming machine (10, 10A) is housed inside the opening; Have
The inner frame case (320, 320A) is prepared with a plurality of standards corresponding to each of the plurality of types of gaming machines (10, 10A),
The outer frame case (310) is a common standard in which the inner frame cases (320, 320A) of the plurality of standards can be attached and detached.
A hanging curtain plate (315) is provided at the upper edge of the opening of the outer frame case (310) so as to be openable and closable with the upper edge as the center of swinging.
A lower end edge of the curtain plate (315) is held at a closed position with a swing angle corresponding to the position of the gaming machine (10) installed in the inner frame case (320). Frame (300).

The present invention operates as follows.
According to the gaming machine installation frame (300, 300A), the installation work can be easily performed when installing the gaming machine (10, 10A) on the gaming machine island (4). Moreover, when the gaming machine (10, 10A) already installed on the gaming machine island (4) is later replaced with another gaming machine (10, 10A), the replacement work can be performed very easily. .

  That is, the gaming machine installation frame (300, 300A) has a double structure having an outer frame case (310) and an inner frame case (320, 320A), and there are a plurality of inner frame cases (320, 320A). A plurality of standards corresponding to each type of gaming machine (10, 10A) are prepared, and the outer frame case (310) is a common type in which all of the inner frame cases (320, 320A) of a plurality of standards can be attached and detached. It has become a standard.

  In order to install the gaming machine (10, 10A) or the like on the gaming machine island (4), first, the outer frame case (310) is attached to the installation location (4a) on the gaming machine island (4). Here, once attached, the outer frame case (310) is not replaced later, and is fixed to the gaming machine island (4) so that it cannot be easily removed. Next, the inner frame case (320, 320A) is attached inside the opening from the front side of the outer frame case (310).

  The inner frame case (320, 320A) is assumed to be removable from the outer frame case (310), and is detachably attached to the outer frame case (310). Then, the gaming machine (10, 10A) is housed inside the opening on the front side of the inner frame case (320, 320A). When exchanging the gaming machine (10, 10A) with another model, after removing the gaming machine (10, 10A) from the inner frame case (320, 320A), the inner frame case (320, 320A) is also the outer frame. It is removed from the case (310), and the outer frame case (310) is left as it is on the gaming machine island (4) side.

  Then, a standard inner frame case (320, 320A) corresponding to another game machine (10, 10A) to be newly replaced is prepared, and the inner frame case (320, 320A) is attached to the outer frame case (310). After that, another gaming machine (10, 10A) or the like may be stored inside the inner frame case (320, 320A). The outer frame case (310) is shared regardless of the type of the gaming machine (10, 10A) and is used repeatedly. With such a gaming machine installation frame (300, 300A), the gaming machine (10, 10A) can be replaced very easily.

  Further, a hanging curtain plate (315) is provided at the upper end edge of the opening of the outer frame case (310) so as to be openable and closable with the upper end edge as a swing center. The lower end edge of the curtain plate (315) is held at a closed position with a swing angle corresponding to the position of the gaming machine (10) installed in the inner frame case (320). Thereby, even if gaps with various widths are generated from the upper edge of the opening of the outer frame case (310) to the upper end of the gaming machine (10) inside the inner frame case (320), the width of these gaps is reduced. Accordingly, the gap can be closed by appropriately tilting the curtain plate (315).

  According to the gaming machine installation frame according to the present invention, when installing a gaming machine, not only can the installation work be performed easily, but also when an already installed gaming machine is later replaced with another model. The replacement work can be performed very easily.

The gaming machine island 1 is a so-called single island that is configured independently by circulating and using gaming balls. The game ball polishing apparatus 200 is combined as a part of the game ball lifting apparatus 100.

  The gaming machine 10 plays a game using a pachinko ball as a game ball. Adjacent to the left end of the gaming machine 10, a ball lending machine (card unit) 20 that lends a game ball by inserting a card or banknote is provided in parallel. As shown in FIG. 2 and FIG. 3, the gaming machine 10 overflows from the front lower portion of the gaming machine 10 with a handle 11 for launching a game ball on the game board surface in the machine, an upper tray 12 for storing the game ball to be launched, and an upper tray 12. A lower tray 13 or the like for receiving a game ball is provided. The ball lending machine 20 pays out the game balls lent to the player to the upper tray 12 from the inside of the gaming machine 10, but there is also a type in which the ball lending machine 20 pays out from the ball rental machine 20 itself to the upper tray 12 via a nozzle.

  Further, on the top plate located below the lower tray 13, there is provided a ball ball specification prize ball counter 14 that can drop the game balls in the lower tray 13 at any time. The prize ball counter 14 is integrally combined with the ball lending machine 20 as a unit, and is called a so-called each counter. Since the prize ball counter 14 is already general, a detailed description thereof is omitted, but when the game balls stored in the ball box portion are discharged into the game machine 10 from the discharge port on the bottom surface, Counting with a sensor while aligning in a line in an alignment lane.

  As shown in FIGS. 1 and 3, a ball collection tank 30 is disposed below the back side of the gaming machine 10, and a prize ball collection basket 40 is disposed separately from the ball collection tank 30. The incoming ball collection tank 30 receives the “incoming ball”, which is a game ball thrown into the gaming machine 10 by the rotation operation of the handle 11 by the player, and aligns later through an incoming ball collecting basket 31 (see FIG. 3). It is delivered to the rail 130. On the other hand, the prize ball collection basket 40 receives a “prize ball” which is a game ball acquired by the player from the gaming machine 10 from the prize ball counter 14 and delivers it to the alignment rail 130.

  As shown in FIGS. 1, 3, and 4, the game ball lifting device 100 is erected along the rear of the right end of the game machine 10, and receives a ball received from the ball collection tank 30 and the prize. The prize balls received from the ball collection basket 40 are each lifted separately. The game ball lifting device 100 includes a spiral body 110 that is rotationally driven around an axis in a state that extends in the vertical direction over the entire length, and extends in the vertical direction along the outer periphery of the spiral body 110, and between the pitches from the outer peripheral side of the spiral body 110. A pair of lifting paths 121 and 122 are provided to guide the game ball in which a part is fitted upward along with the rotational drive of the spiral body 110.

  As shown in FIGS. 5 to 8, each of the feed paths 121 and 122 is formed inside a pipe body 101 that extends in the vertical direction. The pipe main body 101 is formed with an insertion passage 102 that is a vertical hole having a circular cross section that extends along the axial center over the entire length of the pipe body 101 and allows the spiral body 110 to be inserted therethrough. The insertion path 102 is set to an inner diameter that can hold the outer periphery of the spiral body 110 without hindering the rotational drive of the spiral body 110. On both sides of the insertion passage 102, the respective feed paths 121 and 122 are formed as vertical holes extending in parallel with the insertion passage 102.

  Each of the feed paths 121 and 122 is formed as a vertical hole having an arc-shaped cross section that extends symmetrically along both sides of the insertion path 102 and communicates over the entire length of the insertion path 102. Each of the transport paths 121 and 122 is set to an inner diameter that can hold the outer periphery of the game ball without hindering the movement of the game ball. A part of the game ball that is accommodated in each of the transport paths 121 and 122 protrudes into the insertion path 102 and fits between pitches from the outer peripheral side of the spiral body 110 described later. In addition, the concrete cross-sectional shape of each of the lifting paths 121 and 122 is sufficient as long as it can hold a game ball, and is not necessarily limited to a circular shape.

  One of the transport paths 121, 122 is the entrance ball transport path 121 for transporting the entrance ball received from the entrance ball collection tank 30, and the other is the prize ball received from the prize ball collection basket 40. Each is set as a prize ball transport path 122 to be transported. The pipe body 101 may be formed by drilling the insertion passage 102 and the respective feeding passages 121 and 122 later in the integrally molded product, or alternatively, the insertion passage on the mutually facing surfaces of the two divided members. The member divided into two parts may be bonded together after cutting or forming 102 and each of the feed paths 121 and 122 by half.

  As shown in FIG. 6, the upper end side of the pipe main body 101 has a main pipe portion 103 that forms the upper end port of the insertion passage 102 and a pair of branch pipe portions that form upper end outlets of the feeding passages 121 and 122 on both sides thereof. 104 and 104 are formed in three crotch. An entrance counting means 123 for counting the entrances passing through the entrance pumping path 121 is provided at the upper end exit of the entrance pumping path 121. Also, at the upper end exit of the prize sphere transport path 122, a prize sphere counting means 124 for counting the prize spheres passing through the prize sphere transport path 122 is provided. The incoming ball counting means 123 and the prize ball counting means 124 are provided in the corresponding branch pipe sections 104, respectively.

  Each of the entrance ball counting means 123 and the prize ball counting means 124 is capable of detecting one game ball passing through the upper end exit, and specifically, for example, various kinds of sensors such as an optical sensor, a proximity sensor, or a magnetic sensor. What is necessary is just to comprise by a sensor. The entrance ball counting means 123 and the prize ball counting means 124 are respectively connected to control means (not shown) via signal lines, like the prize ball counting machine 14. The control means is composed of a microcomputer having a CPU, a ROM, and a RAM, and controls various related devices installed in the gaming machine island 1.

  The spiral body 110 is formed of a coil spring formed by bending a metal wire in a spiral shape. The spiral body 110 is inserted through the insertion passage 102 in a state of extending in the vertical direction over the entire length thereof, and is driven to rotate around an axis. The gap between the pitches of the spiral body 110 is set to be smaller than the outer diameter of the game balls, and the game balls introduced from the lower end inlets of the respective transport paths 121 and 122 are spaced from the outer periphery of the spiral body 110 to the pitch. In a state where the portion is fitted, the spiral body 110 is lifted upward along with the rotational drive.

  As shown in FIGS. 5 and 6, the spiral body 110 includes a hollow portion 111 that communicates with the gap between the pitches and extends in the axial direction. However, in the coil spring according to the present embodiment, the entire inside is directly intact. It has become. The hollow portion 111 is set as a falling path for foreign matter separated from the game ball being transported. In addition to the coil spring, the spiral body 110 has, for example, a structure in which screw blades are attached to the outer periphery of the cylinder, and slits are appropriately formed in the gaps between the pitches of the screw blades so that each slit communicates with the inside of the cylinder. Can be considered.

  An upper end port 113 of the spiral body 110 extends above the pipe body 101 and is attached to a main shaft 145 described later via a terminal cap 114. Thereby, the helical body 110 is driven to rotate by a power source in a form of pulling up instead of pushing the game ball upward from below. Further, the lower end 112 of the spiral body 110 extends below the pipe body 101, and is arranged so as to be freely rotatable while penetrating through a foreign matter discharge opening 133 in the alignment rail 130 described below. Yes.

  As shown in FIGS. 1, 3, and 5, an incoming ball that is a game ball to be transported and a prize ball are separately received and supplied to the lower end side of the spiral body 110 and the transport paths 121 and 122. An alignment rail 130 is provided. The alignment rail 130 is disposed between the downstream ends of the incoming ball collection basket 31 and the prize ball collection basket 40 and the lower end side of the pipe body 101. The alignment rail 130 guides the incoming ball delivered from the incoming ball collecting basket 31 to the lower end entrance of the incoming ball feeding path 121, and the incoming ball delivered from the prize ball collecting basket 40 to the prize ball lifting path 122. It leads to the lower end entrance.

  As shown in FIGS. 9 to 14, the alignment rail 130 is integrally formed of a synthetic resin, and includes an incoming ball collection path 131 that receives incoming balls, a premium ball collection path 132 that receives premium balls, and the spiral body 110. A foreign matter discharge opening 133 is formed to pass through. The incoming ball collection path 131 flows down from one end side connected to the downstream end of the incoming ball collection basket 31 to the other end side connected to the lower end inlet of the incoming ball feeding path 121 in a state where the incoming balls are aligned in a line. It is formed in a concave cross-sectional shape, and is gently inclined downward from one end side to the other end side.

  The prize sphere collection path 132 is gradually lined up from a multi-row state from one end side connected to the downstream end of the prize sphere collection basket 40 to the other end side connected to the lower end inlet of the prize sphere lifting path 122. It is formed in a concave cross-sectional shape that allows it to flow down in an aligned state. The concave section of the prize ball collection path 132 is formed wide at one end side to receive multiple rows of prize balls, but the other end side is gradually narrowed and has a groove width for aligning the prize balls in a line. Become. Further, the prize ball collecting path 132 is gently inclined downward from one end side to the other end side, and extends from a side edge extending in an arc shape near the ball collecting path 131 to a side end edge extending in a straight line on the opposite side. In addition, a slope with a round cross-sectional shape is provided.

  As shown in FIG. 5, the pipe body 101 is erected vertically on the other end side of the alignment rail 130. The insertion passage 102 of the pipe body 101 and the opening 133 of the alignment rail 130 communicate with each other in the vertical direction. The spiral body 110 extends downward from the lower end of the pipe body 101, and the lower end port 112 of the spiral body 110 extends further downward and is exposed to the outside in a state of passing through the opening 133. The gaming machine installation frame 2 is provided with a foreign matter discharge port 3 that faces the lower end port 112 of the spiral body 110 at a position that is located just below the opening 133.

  The lower end inlet of each of the transporting paths 121 and 122 is connected to the downstream end which is the other end side of the ball collection path 131 and the prize ball collection path 132 of the alignment rail 130, respectively. As shown in FIGS. 9 and 10, the downstream ends of the collection paths 131 and 132 are arranged in line symmetry with respect to the axis of the opening 133 (the spiral body 110 passing through). Here, the downstream ends of the collection paths 131 and 132 are set in a direction in which game balls are discharged along the rotation direction of the spiral body 110.

  In addition, portions of a predetermined length that follow the downstream ends of the incoming ball collection path 131 and the prize ball collection path 132 are disposed so as to extend in parallel to the diameter direction of the spiral body 110. As will be described in detail later, the arrangement of the collection paths 131 and 132 on the downstream end side as described above will be described in detail below until the first game ball in contact with the helical body 110 is lifted at the lower end inlet of each of the lift paths 121 and 122. The next game ball is not in contact with the spiral body 110.

  In addition, a game that overlaps the upper stage of the game balls lined up in a line that has flowed down the collection paths 131 and 132 at a position just before one game ball from the downstream ends of the entrance collection path 131 and the prize ball collection path 132. A rib 134 is provided that contacts the ball and prevents the upper game ball from entering, and prevents back flow of the game ball that has reached the lower end inlet of each of the corresponding transport paths 121 and 122.

  As shown in FIGS. 10 to 12, in detail, the rib 134 protrudes with a predetermined width at a position higher by one game ball than the inner wall of the downstream end of each recovery path 131, 132. The ribs 134 allow the game balls to pass through without protruding from the inner walls of the downstream ends of the collection paths 131 and 132 on the lower end side, but prevent the game balls from passing through the portions protruding from the inner walls of the downstream ends. As shown in FIGS. 13 and 14, the predetermined width of the rib 134 is set to such a width that the upper game ball that is blocked from passing the game ball that passes through the lower end side of the rib 134 does not come into contact. .

  With such ribs 134, as will be described in detail later, game balls are smoothly introduced into the lower end inlets of the respective transport paths 121, 122 one by one. Since the rib 134 has an undercut shape in the alignment rail 130, it cannot be integrally formed together with the entire alignment rail 130, and is formed as a separate body as shown in FIGS. 15 and 16. It is attached later to the inner wall at the downstream end of 132. On the lower end side of the rib 134, a tapered groove 135 that is curved downward is provided so as to gradually push the game ball downward toward the lower end inlet of each of the transport paths 121 and 122.

  As shown in FIGS. 1 and 18, a game ball polishing apparatus 200 for polishing the game balls after being lifted is disposed on the upper end side of each of the transfer paths 121 and 122. A power source for driving the game ball polishing apparatus 200 includes an electric motor 140 shared with the power source for rotationally driving the helical body 110. Furthermore, a storage unit 150 is provided above the game ball polishing apparatus 200 for receiving and storing the game balls released from the upper end outlets of the respective transport paths 121 and 122.

  The game ball polishing apparatus 200 is disposed just above the upper end port 113 of the spiral body 110 and is disposed along the outer periphery of the polishing gear 210 that is driven to rotate coaxially with the spiral body 110. A polishing means for polishing in contact with a game ball partially exposed from the tooth groove 212a of the polishing gear 210, and a game ball sequentially pushed by the rotational drive of the polishing gear 210 to a storage unit 150 to be described later And a transfer path 230 for guiding.

  As shown in FIG. 23, the grinding gear 210 is rotatably supported in a cylindrical casing 220 and attached to the base frame 201. The electric motor 140 as a power source is also attached to the base frame 201. The grinding gear 210 is formed in a substantially cylindrical cylinder shape, and is rotatably supported around the axis of the main shaft 145 that penetrates the grinding gear 210. Bearing portions 211a and 211b through which the main shaft 145 penetrates relatively rotatably are provided at the upper and lower ends of the grinding gear 210.

  As shown in FIG. 22, the grinding gear 210 is formed in a cylindrical shape as a whole. More specifically, the upper portion of the polishing gear 210 is a large diameter portion 210a, and the guide teeth 212 are formed along the outer periphery of the large diameter portion 210a so as to extend along the generatrix of the column surface. The tooth gap 212a between the guide teeth 212 is formed in an arcuate cross-sectional shape so as to embrace more than half of the game ball.

  The groove opening of the tooth groove 212a is set to be narrower than the maximum diameter of the game ball so that the game ball cannot be detached from the tooth groove 212a to the outside. That is, the tooth groove 212a can guide the game ball received from the upper end side of the tooth groove 212a to the lower end side, and a plurality of game balls are sequentially accommodated in the tooth groove 212a in a state of overlapping vertically.

A large-diameter receiving port 151 leading to the upper end opening of the tooth gap 212a is opened. However, a part of the receiving port 151 is covered and closed by a cover part 150 a that forms the bottom of the storage part 150.

  In addition, a pair of discharge ports 152 and 152 are provided near the receiving port 151 at the bottom of the storage unit 150 so that the upper end outlets of the transport paths 121 and 122 communicate with each other. Each discharge port 152 is connected to each branch pipe portion 104 which is an upper end outlet of each of the transport paths 121 and 122. Here, each discharge port 152 and each branch pipe portion 104 are indirectly connected via a deformable or extendable bellows pipe 105.

  As shown in FIG. 23, a polishing opening 221 is formed in the cylindrical wall of the middle part of the casing 220. The polishing opening 221 allows the polishing sheet 240 (see FIG. 24) constituting the polishing means to enter from the outside to the inside and be routed along the outer periphery of the guide tooth 212 of the polishing gear 210. It is made up. As the polishing gear 210 is driven to rotate, the polishing ball 240 is repeatedly brought into contact with the gaming ball partially exposed from the tooth groove 212a, whereby the gaming ball is polished. The details of the polishing sheet 240 will be described later.

  As shown in FIG. 18, a transfer path 230 is connected to the lower part of the casing 220 to guide the game balls sequentially pushed downward along with the rotational drive of the grinding gear 210 to the storage unit 150 again. ing. The inner peripheral wall of the lower part of the casing 220 abuts against the game balls guided by the tooth grooves 214a of the locking teeth 214 and pushes the game balls toward the lower end inlet of the transfer path 230 in a state of being aligned in a row. Guide ribs 222 are provided.

  The transfer path 230 has an inner diameter that is slightly larger than the diameter of the game balls, and is composed of a pipe member that transfers the game balls in a state of being aligned in a row. The transfer path 230 is curved obliquely upward from a lower end inlet connected to the lower portion of the casing 220, and the upper end outlet is connected to a reintroduction port 153 opened at the bottom of the storage unit 150. As shown in FIG. 20, the reintroduction port 153 is arranged at a position farther from the discharge ports 152 than the receiving port 151 that is also opened at the bottom of the storage unit 150.

  As shown in FIGS. 18 to 20, the bottom of the reservoir 150 is directed from the position including each discharge port 152 and the reintroduction port 153 toward the receiving port 151 on one end side with the reintroduction port 153 as a boundary. A polishing slope 150b is formed to allow the game ball to flow down under its own weight. An inclination top end 150c which is the uppermost position of the polishing inclination 150b is arranged so as to extend in a diameter direction of the reintroduction port 153, and a game ball is directed from the inclination top end 150c toward the other end side of the storage portion 150. A replenishment slope 150d is formed so as to flow down under its own weight.

  A partition wall 150e is provided between each discharge port 152 and the reintroduction port 153 so as to guide the game ball released from the reintroduction port 153 to the receiving port 151 while avoiding the vicinity of each discharge port 152. Yes. The game balls discharged from the reintroduction port 153 are not directly directed to the receiving port 151 by the partition wall 150e as shown by the arrows indicating the flow of the game balls in FIG. It flows down the slope 150b and is introduced into the receiving port 151 so as to go around.

  A replenishment basket 160 is connected to the other end side of the storage unit 150. The replenishment basket 160 is disposed so as to extend obliquely downward from the other end side of the storage unit 150 over the gaming machine 10. When the storage unit 150 is filled with game balls and the storage amount is excessive, the excess game balls are set so as to get over the inclined top end 150c and flow into the supply tank 160 through the supply inclination 150d. .

  As shown in FIGS. 18 and 20, a detection sensor 161 for detecting the presence or absence of a game ball is provided on the upstream side of the supply basket 160. The detection sensor 161 is continuously turned on when the game ball stays on the upstream side of the replenishing bowl 160, and when the ON state continues for a predetermined time (for example, 2 seconds) or more, the game ball is full. Is set to output the signal. The detection sensor 161 is specifically configured by, for example, a photoelectric switch, a level switch, a limit switch, or the like.

  Further, a distribution chute 162 for supplying the gaming machine 10 in a state where the flowing game balls are aligned is disposed in the middle of the supply basket 160. Here, as the distribution chute 162, for example, the invention described in Japanese Patent Application Laid-Open No. 2011-104042 that has already been proposed by the applicant may be used. The distribution chute 162 and the gaming machine 10 communicate with each other via a bellows 163 that guides a falling game ball. In FIG. 1, a bellows 163 connecting the distribution chute 162 and the ball lending machine 20 is closed in this embodiment so as not to pay out game balls from the ball lending machine 20 itself.

  As shown in FIGS. 18 and 23, an electric motor 140 is attached to the side of the grinding gear 210 in the base frame 201. A gear head 141 and a drive shaft 141a are integrally assembled with the electric motor 140. Two large and small spur gears 142 and 143 having different outer diameters are fixed to the drive shaft 141a. A spur gear 215 is fixed to the bearing portion 211 a of the grinding gear 210, and a timing belt 144 is wound around the spur gear 215 and the spur gear 142. As a result, the grinding gear 210 is configured to rotate by receiving the power of the electric motor 140.

  A terminal cap 114 is attached to the upper end opening 113 of the helical body 110, and the lower end of the main shaft 145 is connected to the terminal cap 114 so as to be integrally rotatable. A spur gear 115 is fixed immediately above the terminal cap 114 in the main shaft 145, and a timing belt 146 is wound around the spur gear 115 and the spur gear 143. Accordingly, the helical body 110 is configured to be driven to rotate by transmitting the power of the electric motor 140.

  As shown in FIG. 23, the polishing means accommodates the polishing sheet 240 (see FIG. 24) disposed in the polishing opening 221 of the casing 220 and the polishing gear 210 while accommodating the polishing sheet 240. A storage case 250 that can be attached to and detached from the position, a feeding mechanism that feeds the polishing sheet 240 out of the housing case 250 and moves it along the outer periphery of the grinding gear 210, and the feeding mechanism that rotates the grinding gear 210. And an interlocking mechanism for interlocking.

  An interlocking mechanism is disposed on the side of the gear head 141 of the electric motor 140. This interlocking mechanism includes a support bracket 270 and three shafts 271 to 273 that are rotatably supported in the support bracket 270. Within the support bracket 270, the rotation of the shaft 271 is transmitted to the shaft 272 via the worm and the worm wheel, and the rotation of the shaft 272 is transmitted to the shaft 273 via the worm and the worm wheel.

  A feeding roller 274 for feeding the polishing sheet 240 is fixed to the shaft 273. On the outer peripheral surface of the feeding roller 274, knurling for preventing slippage and other notches are formed. The feeding roller 274 constitutes a main part of the feeding mechanism, and is set to be interlocked with the rotational drive of the grinding gear 210 by the interlocking mechanism described above. The shaft 271 is configured to transmit the rotational force of the drive shaft 141a via a transmission mechanism such as a pulley.

  The feeding roller 274 feeds the polishing sheet 240 from the storage case 250 described below at a speed corresponding to the moving speed of the game ball by the guide teeth 212 when the polishing gear 210 is driven to rotate. It is comprised so that it may move along an outer periphery. That is, the interlocking mechanism moves the polishing sheet 240 by the feeding mechanism at a speed obtained by reducing the rotational speed of the polishing gear 210 by a predetermined ratio.

  As shown in FIG. 23, the storage case 250 of the polishing sheet 240 is detachably attached at a position facing the polishing opening 221 of the casing 220. As shown in FIGS. 24 and 25, the storage case 250 has a cassette case shape for storing the polishing sheet 240. The casing 220 is provided with a lock member 258 for restraining the storage case 250 in a mounted state.

  Specifically, the lock member 258 is formed in an arm shape, its base end is pivotally supported so as to be swingable, and a stopper 259 is provided at the swing end. The stopper 259 is set so as to be able to be engaged and disengaged from one direction with respect to the curved front end surface of the storage case 250 in a state of being attached to the casing 220. As shown in FIG. 24, when the lock member 258 is swung until it becomes parallel to the longitudinal direction of the storage case 250, the stopper 259 engages with the front end surface of the storage case 250 and is restrained in a state where the storage case 250 is mounted. can do.

  The polishing sheet 240 is a thin non-woven fabric made of a material capable of polishing the game ball, and is accommodated in a state of being wound around a cylindrical winding shaft 241 shown in FIG. The polishing sheet 240 is fed out from the storage case 250 by the feeding mechanism and used for polishing, and is then collected in the storage case 250 again. In the storage case 250, a partition wall 252 for separating the unused portion of the polishing sheet 240, that is, the portion still wound around the winding shaft 241 and the used portion recovered again in the storage case 250, is arranged. Has been. The partition 252 is a wall-like member erected in the illustrated shape.

  The front surface portion of the storage case 250 is formed in a cross-sectional shape that is recessed in an arc shape along the outer periphery of the polishing gear 210, and a cushion member 253 is attached to this portion. The cushion member 253 is formed of an elastic material such as felt. The polishing sheet 240 passes through a guide groove 254 on one side end side of the storage case 250 and is fed to one end side of the cushion member 253 so that the game ball on the polishing gear 210 side can be pressed by the elastic force of the cushion member 253. In this state, the cushion member 253 is extended from one end side to the other end side along the outer periphery of the guide tooth 212.

  The front end side of the portion used for polishing the polishing sheet 240 is again collected in the storage case 250 by the feeding mechanism. A holding roller 255 is rotatably supported on the side of the storage case 250 facing the guide groove 254 so as to be in contact with the feeding roller 274 and sandwich the abrasive sheet 240 therebetween. The outer peripheral surface of the holding roller 255 is formed of an elastic material such as urethane.

  The polishing sheet 240 is sequentially collected in the storage case 250 as the feeding roller 274 is driven in a state where the polishing sheet 240 is sandwiched between the feeding roller 274 and the holding roller 255. . Here, the used portion collected in the storage case 250 is stored in a space defined by the partition 252 while being freely folded. As shown in FIG. 25, the upper surface side of the storage case 250 is formed as a lid portion 256 that can be opened and closed.

Next, the operation of the above-described embodiment will be described.
In FIG. 2, when starting a game, the player inserts a card or banknote into the ball lending machine 20 and receives a rental amount of game balls for a corresponding amount. In the case of the present embodiment, the rented game balls are paid out directly to the upper tray 12. In the gaming machine 10, the game balls in the upper tray 12 are launched one by one on the game board surface by rotating the handle 11. As described above, the “incoming balls” that are the game balls thrown into the gaming machine 10 are collected in the incoming collection tank 30 shown in FIGS. Passed to the rail 130.

  When game balls launched on the surface of the game board win various prize holes, a predetermined number of game balls are paid out to the upper tray 12. As described above, the “prize balls”, which are the game balls acquired by the player from the gaming machine 10, are collected in the prize ball counter 14 via the lower tray 13, and then counted as a count based on the player's operation. 3 and FIG. 4, it flows down along the inclination of the prize ball collection basket 40 and is delivered to the alignment rail 130. The count result of the prize sphere by the prize sphere counter 14 is output to the control means and is managed.

  As shown in FIG. 4, an alignment rail 130 is arranged at the downstream end of the incoming ball collecting basket 31 and the prize ball collecting basket 40, and the game balls are divided into the incoming ball and the premium ball separately by the alignment rail 130. It is supplied to the game ball lifting device 100 as it is. As shown in FIGS. 9 and 10, the alignment rail 130 has a ball collection path 131 for receiving a ball and a prize ball collection path 132 for receiving a prize ball, and the corresponding lifting paths 121 and 122 respectively. The entrance ball and the prize ball can be led separately to the lower end entrance of the.

  The incoming balls received in the incoming ball collecting path 131 flow down in the incoming ball collecting path 131 in a state of being aligned in a line, and are guided to the lower end entrance of the incoming ball feeding path 121. On the other hand, in many cases, the prize sphere collection path 132 accepts a large amount of prize spheres at a time in a multi-row state, and the prize sphere received in the prize sphere collection path 132 flows down in the prize sphere collection path 132. Gradually gathered from the multi-row state, and finally led to the lower end entrance of the prize ball lifting path 122 in a state of being aligned in a line as in the ball collection path 131.

  Generally, in the gaming machine 10, the incoming balls are sequentially discharged into the machine, but the prize balls are often discharged at a time. In accordance with such characteristics, according to the entrance collection path 131 and the prize ball collection path 132, it is possible not only to distinguish and receive the entrance ball and the prize ball, but also to efficiently accept each assumed number of game balls. It becomes possible, and it can be quickly and smoothly delivered separately to the incoming ball transport path 121 and the prize ball transport path 122, and the transport capacity can be increased. Since the bottom of the prize sphere collecting path 132 has the above-described slope of the cross-sectional shape, not only the prize spheres are efficiently aggregated in a row, but also dust accumulates on the bottom of the prize sphere collecting path 132. Can be prevented.

  As shown in FIG. 9 to FIG. 12, the rib 134 described above is provided at a position in front of one game ball from the downstream end of each recovery path 131, 132. As indicated by a in FIG. 13, the rib 134 abuts against the game balls that overlap the upper stage of the game balls that have flowed down the collection paths 131 and 132, and prevents the upper game balls from entering. Can do. Further, the game balls that have reached the lower end inlets of the respective transport paths 121 and 122 are subjected to a force in the direction of being pushed back as shown by b in FIG. The backflow of the game ball can be prevented by the tapered groove 135. Furthermore, as indicated by c in FIG. 13, the rib 134 is set to such a width that the upper game ball that is blocked from passing the game ball that passes through the lower end side of the rib 134 does not come into contact. Further, it is possible to prevent clogging of the balls and to prevent the ribs 134 from being damaged.

  Further, as shown in FIG. 17A, the downstream ends of the recovery paths 131 and 132 are arranged symmetrically with respect to the axial center of the spiral body 110, and are portions of a predetermined length following the respective downstream ends. Are arranged in parallel to each other with respect to the diameter direction of the spiral body 110. Thus, the next game ball is not in contact with the spiral body 110 until the game ball that reaches the lower end entrance of each of the transport paths 121 and 122 and first contacts the spiral body 110 is lifted. That is, in FIG. 17A, the second game ball following the first game ball comes into contact with the first game ball (P1), and also comes into contact with the inner walls of the downstream ends of the collection paths 131 and 132 (P2). ) Alone, and does not contact the spiral 110 further.

  As a result, even if the lower end side of the spiral body 110 meanders, the second game ball following the first game ball that has reached the lower end entrance of each of the transport paths 121 and 122 becomes the first game ball and each transport path. In addition to the inner walls of 121 and 122, there is no situation in which the spiral body 110 is brought into contact and engaged at three points, and it is possible to prevent the occurrence of a ball clogging due to the formation of a bridge of game balls due to such a situation. .

  As shown in FIG. 17B, if the portions of a predetermined length following the downstream end of the recovery path 131 are not parallel to each other in the diameter direction of the spiral body 110, the first game ball is lifted. If the lower end side of the spiral body 110 meanders at the time, the second game ball contacts the first game ball (P1), contacts the downstream end inner wall of the recovery path 131 (P2), and further contacts the spiral body 110. (P3) Therefore, there is a high possibility that a ball clogging due to the bridge formation of the game ball due to the engagement at the three points will occur.

  With the alignment rail 130, the game balls are supplied to the game ball lifting device 100 while the incoming balls and the prize balls are distinguished. When the helical body 110 of the game ball lifting device 100 is rotationally driven, the game balls are lifted from the lower end inlets of the respective transport paths 121 and 122 along the pipe body 101 standing on one end side of the alignment rail 130. The The electric motor 140 that rotationally drives the helical body 110 operates in response to a signal output from the detection sensor 161 (see FIG. 18) on the upstream side of the replenishing rod 160.

  In FIG. 5, a part of the game balls introduced in a row with respect to the lower end inlets of the respective transport paths 121 and 122 are fitted between the pitches from the outer peripheral side of the spiral body 110, and the spiral body 110 is driven to rotate. Along with this, the inside of each of the transport paths 121 and 122 is moved upward. The spiral body 110 includes a hollow portion 111 that communicates with a gap between pitches and extends in the axial direction, and foreign matter separated from the game ball being transported enters the hollow portion 111 through the gap. become.

  Since the hollow part 111 serves as a foreign substance drop path, the foreign substance that has entered the hollow part 111 is dropped and discharged to the outside. The lower end port 112 of the spiral body 110 extends below the pipe main body 101, and is disposed so as to be freely rotatable while penetrating through a foreign matter discharge opening 133 in the alignment rail 130. Thereby, the foreign material separated from the game ball can be easily discharged outside without staying in the pipe body 101. The foreign matter dropped from the lower end port 112 of the spiral body 110 is discharged to the outside from the foreign matter discharge port 3 in the gaming machine installation frame 2.

  The spiral body 110 extends in the vertical direction over the entire length, has no horizontal or curved portion, and there is no possibility that foreign matter may stay in the middle of the hollow portion 111. Further, in the present embodiment, the helical body 110 is formed of a coil spring, and the inside of the coil spring is directly used as the hollow portion 111, so that it can be configured very simply. Moreover, since the space | interval of the coil spring is a wide clearance gap and the wide hollow part 111 is obtained according to the magnitude | size of an outer diameter, the efficiency which takes in and discharges a foreign material can be improved.

  Further, by providing the pumping paths 121 and 122 so as to be arranged at equal intervals with the axis of the spiral body 110 in between, it is possible to efficiently separate the incoming ball and the premium ball in a limited space. It becomes possible to do. Here, each of the lifting paths 121 and 122 becomes a landing ball feeding path 121 for lifting the incoming ball, and the other becomes a prize ball lifting path 122 for lifting the prize ball. In the process, it is possible to clearly distinguish the incoming ball and the premium ball. Thereby, it is possible to count game balls for each of the transport paths 121 and 122.

  That is, as shown in FIG. 1, there is an entrance counting means 123 for counting entrances passing through the entrance pumping path 121 at the upper end exit of the entrance pumping path 121. Has a prize sphere counting means 124 for counting the prize spheres passing through the prize sphere transporting path 122, and the entrance sphere and the prize sphere can be separately counted in the process of lifting the game sphere. Each of the counting means 123 and 124 is specifically composed of a sensor, and outputs a pulse signal each time a game ball is detected. These pulse signals are input to the control means and collected and managed in the backup memory.

  The prize sphere is counted by the prize sphere counter 14 separately from the prize sphere counting means 124 before being introduced into the prize sphere transporting path 122. The counting result by the prize ball counter 14 is also input to the control means separately from the counting result of the prize ball counting means 124 and collected and managed. Here, the control means has determination means as one of the control program functions, and the determination means outputs the count result output from the prize ball counting means 124 and the count result output from the prize ball counter 14 by the determination means. Comparison is made to determine whether or not the count results match. If the counting results do not match, it is possible to know a spilled ball or a malfunction of the prize sphere counting means 124 or the prize sphere counter 14.

  Further, in the process of lifting the game ball by the game ball lifting device 100, the game ball being lifted is not polished. Therefore, the frictional resistance applied to the polishing of the game ball does not directly apply a load to the drive system of the game ball lifting device 100. In addition, it is possible to prevent a situation in which an excessive force is applied to the spiral body 110 that may occur when the game ball is polished in the middle of the spiral body 110. In the present embodiment, a game ball polishing apparatus 200 for polishing the game ball after being lifted is disposed above the pipe body 101.

  Thus, by lifting the game ball and then polishing it again, it is possible to more sufficiently polish the relatively less dirty game ball from which foreign matter has been removed in the above-described lifting process. Become. Although the game ball polishing apparatus 200 is provided separately from the spiral body 110 or the lifting paths 121 and 122, the electric motor 140, which is a power source for driving the game ball polishing apparatus 200, is rotated by the spiral body 110. By sharing the driving power source, it is possible to reduce the number of parts and power consumption, thereby preventing an extra cost increase.

  In FIG. 18, the rotation of the spur gear 143 due to the operation of the electric motor 140 is transmitted to the spur gear 115 via the timing belt 146, whereby the integral helical body 110 is connected to the pipe via the spur gear 115 and the main shaft 145. It is driven to rotate within the main body 101. Similarly, the rotation of the spur gear 142 by the operation of the electric motor 140 is transmitted to the spur gear 215 via the timing belt 144, whereby the integral grinding gear 210 is connected to the casing via the spur gear 215 and the main shaft 145. It is driven to rotate within 220.

  In FIG. 18, the incoming ball and the prize ball that are lifted through the respective lifting paths 121 and 122 pass through the bellows pipe 105 connected to the branch pipe portion 104 at the upper end of the pipe body 101, and are respectively released. It is discharged from the outlet 152 into the storage unit 150 and stored. The incoming ball and the prize ball are mixed in the storage unit 150 and are reliably guided to the receiving port 151 by the polishing inclination 150b. The game ball that has dropped to the receiving port 151 flows into the tooth groove 212 a of the grinding gear 210. The game ball entering the upper end side of the tooth groove 212a moves to the lower end side of the tooth groove 212a by its own weight, and a new game ball enters the upper end side of the tooth groove 212a.

  The game balls in the tooth groove 212a are sequentially guided to the lower end side of the tooth groove 212a with the rotational drive of the grinding gear 210 synchronized with the helical body 110. Subsequently, the game balls pass through the tooth grooves 213a through the tooth grooves 214a, and then are aligned in a row by the guide ribs 222 at the lower part of the casing 220. The game balls pass through the transfer path 230 and enter the storage portion 150 again from the reintroduction port 153. Released. Here, since the reintroduction port 153 is located at a position away from each of the discharge ports 152 with respect to the receiving port 151, the game ball that has just been lifted is more easily polished in the storage unit 150.

  The game ball released from the reintroduction port 153 is guided again to the receiving port 151 by the polishing gradient 150b with the reintroduction port 153 as a boundary, or by the replenishment gradient 150d with the reintroduction port 153 as a boundary. When the storage unit 150 is full of game balls, the storage unit 150 faces the replenishment basket 160. Thus, if the inside of the storage unit 150 is not full of game balls, even a game ball that has been ground once falls back to the receiving port 151 and repeatedly flows into the tooth groove 212a of the grinding gear 210. Become.

  As shown in FIGS. 20 and 21, since there are partition walls 150e between the reintroduction ports 153 and the respective discharge ports 152, the game balls released from the reintroduction ports 153 by the partition walls 150e are the respective discharge ports 152. To the receiving port 151 so as to avoid the vicinity. As a result, it is possible to prevent a situation in which a large amount of game balls from the respective discharge ports 152 and reintroduction ports 153 enter the receiving port 151 at one time, and the grinding gear 210 is overloaded and damaged. In addition, it is possible to avoid a situation in which the game balls discharged from the discharge ports 152 and the reintroduction ports 153 collide with each other.

  As long as the game ball is sufficiently supplied to the storage unit 150, the game ball is received without interruption from the tooth groove 212a to the tooth groove 214a shown in FIG. In such a state, the locking ball 214 can push the game ball up to the transfer path 230 again without skipping. Here, since the storage unit 150 has a capacity capable of storing a sufficient number of game balls, the polishing of the game balls will be repeated not only once but several times, and can be reliably polished. it can.

  In the present embodiment, the polishing amount of the game ball per unit time due to the rotational drive of the grinding gear 210 is set larger than the amount of game ball lifted per unit time due to the rotational drive of the helical body 110. Thereby, the game balls in the grinding gear 210 tend to be insufficient, and the game balls in the storage unit 150 are repeatedly polished. By this balance of entering and exiting, it is possible to prevent the game balls that have not been polished from flowing out to the supply basket 160.

  However, it is preferable that the specific speed ratio between the lift amount of the game ball and the polishing amount be maintained in a state where the game ball is stored in the storage unit 150 and can be supplied to the polishing gear 210 at all times. By introducing a sufficient amount of game balls into the tooth groove 212a of the grinding gear 210, not only the polishing efficiency is increased, but also damage to the tooth groove 212a is suppressed. The rotational drive of the grinding gear 210 is also controlled by the control means.

  Further, when the helical gear 110 continues to be lifted and the grinding gear 210 is filled with game balls, and the storage unit 150 is filled with game balls and the storage amount becomes excessive, the excess game balls are Over the slope top end 150c which is the top of the grinding slope 150b, the replenishment slope 150d flows down to the replenishment rod 160. Then, the game balls flowing down the replenishment basket 160 are appropriately supplied to the gaming machines 10 via the distribution chute 162.

  Further, when the replenishment basket 160 is filled with game balls, the detection sensor 161 detects this and stops the operation of the electric motor 140. That is, the lifting operation and the polishing operation are stopped simultaneously. Thereby, unnecessary power consumption can be reduced. Thereafter, when the detection sensor 161 no longer detects the fullness of the game ball, the operation of the electric motor 140 is started after a predetermined time has elapsed.

  Thereby, it is possible to replenish the gaming machine 10 with the ground game ball. Here, instead of starting the operation of the electric motor 140 immediately, the time difference is provided after a predetermined time has elapsed, after which the storage unit 150 is immediately filled with game balls, and the detection sensor 161 is filled with game balls. This is because the case of detecting the above is taken into consideration. The operation of the electric motor 140 is also controlled by the control means.

  As shown in FIG. 23, a polishing opening 221 is formed in a part of the casing 220 in which the polishing gear 210 is stored, and a storage in which the polishing sheet 240 is stored at a position facing the polishing opening 221. A case 250 is attached. When the storage case 250 is mounted, the storage case 250 may be pushed into the polishing opening 221 in the longitudinal direction while the lock member 258 is swung to the unlocking position indicated by the solid line in FIG. .

  After mounting the storage case 250, when the lock member 258 is swung to the lock position indicated by the imaginary line in FIG. 24, the stopper 259 engages with the front end surface of the storage case 250, so the storage case 250 is mounted. Can be constrained to the state. In this state, the polishing sheet 240 is routed along the outer periphery of the polishing gear 210 and comes into contact with the game ball viewed from the tooth gap 212a with an appropriate pressure. Thus, the game ball is repeatedly polished until it moves from the upper end side to the lower end side of the tooth groove 212a.

  The polishing sheet 240 is housed in the storage case 250 in a state of being wound in a roll shape, and an appropriate length is fed by a feeding roller 274 that is interlocked with the rotational drive of the polishing gear 210. In FIG. 23, the rotational force of the drive shaft 141a due to the operation of the electric motor 140 is first transmitted to the shaft 271 in the interlocking mechanism, and the feeding roller 274 is rotationally driven through the engagement of the worms and worm wheels of the shafts 271 to 273. To do. When the feeding roller 274 rotates, the polishing sheet 240 sandwiched between the feeding roller 274 and the holding roller 255 is fed out of the storage case 250 in FIG.

  As described above, when polishing the game ball, the unused polishing sheet 240 can be automatically drawn out from the storage case 250 and used, and the operator does not need to replace the unused polishing sheet 240. Further, when the polishing gear 210 stops rotating by the interlocking mechanism, the rotation of the feeding roller 274 of the feeding mechanism also stops. That is, only when the polishing gear 210 is rotated to polish the game ball, the polishing sheet 240 is fed out from the storage case 250 and the unnecessary polishing sheet 240 is not fed out, so that the consumption cost of the polishing sheet 240 is reduced. It is also possible.

  In FIG. 24, the polishing sheet 240 passes through the guide groove 254 of the storage case 250 and is fed to one end side of the cushion member 253. The fed polishing sheet 240 is extended to the other end side of the cushion member 253 through a gap between the cushion member 253 and the polishing gear 210. At this time, the polishing sheet 240 is in a state where the game ball in the tooth gap 212a can be pressed by the elastic force of the cushion member 253. The used portion of the polishing sheet 240 is stored while being freely folded in the storage case 250 from the other end of the cushion member 253 again.

  In the storage case 250, the unused portion and the used portion of the polishing sheet 240 are separated by the partition 252, so that there is no possibility that dirt on the used portion moves to the unused portion. When there is no unused portion of the polishing sheet 240 in the storage case 250, the used portion stored in the storage case 250 is discarded as "disposable". In order to facilitate the replacement work of the polishing sheet 240, it is preferable to prepare another storage case 250 in which a roll of a new polishing sheet 240 is set in advance and replace the storage case 250 together. When the storage case 250 is removed from the casing 220, the lock member 258 may be swung to the unlock position.
