In the opening of the back mechanism board 3, a rear case of a winning device (not shown) arranged on the game board or a center case (not shown) fitted from the front of the game board into an opening formed in the game board. A rear portion and the like are arranged, and these are covered from behind by a cover 4 attached to the opening of the back mechanism panel 3.

  In the upper part of the back mechanism board 3 is stored an external terminal 10 for electrically connecting the gaming machine 100 to an external device, and a game ball replenished from a replenishment device (not shown) provided in the island facility. A ball storage unit 11 for discharging the stored game balls is provided.

  On the side of the back mechanism board 3 (right side in FIG. 1), the ball discharged from the ball storage unit 11 is discharged to an upper plate and a lower plate (not shown) disposed on the front of the gaming machine. A unit 12 is disposed.

  A discharge control device 13 that controls the ball discharge unit 12 is disposed below the back mechanism board 3.

  The ball storage unit 11 includes a storage tank 14 that can store game balls, and a guide rod 15 that is disposed below the storage tank 14 and guides the game balls supplied from the storage tank 14 to the ball discharge unit 12. . In addition, the guide rod 15 is formed so that the game ball can roll on two lines.

  The ball discharge unit 12 is covered with a cover 16, and a discharge device 20 that discharges a required number of game balls based on the establishment of a predetermined discharge condition is housed in the cover 16.

  Here, the establishment of the predetermined discharge condition means that a game ball launched into the game area from the hitting ball launching device wins each winning opening arranged in the game area, or on the front side of the gaming machine 100 This is the case when a player pushes a ball lending switch on an operation panel (not shown) for the card ball lending unit provided.

  When a game ball wins each winning opening, a prize ball signal is output from the game control device (not shown) to the discharge control device 13, and the discharge device 20 discharges the required number of game balls to an upper plate or the like. . Further, when the ball lending switch is pushed by the player, a ball lending request signal is output from the card ball lending unit (not shown) provided in the gaming machine 100 to the discharge control device 13, and the discharging device 20 Discharge the required number of game balls to the top plate.

  Hereinafter, the discharge device 20 will be described with reference to FIGS. 2 is a perspective view of the discharge device 20, FIG. 3 is a front view showing the internal configuration of the discharge device 20, FIG. 4 is an exploded perspective view of the discharge device 20, and FIG. It is a perspective view. The cross section shown in FIG. 5 is a cross section parallel to the rotation axis of the rotating body.

  The discharge device 20 includes a casing 21 made of a transparent synthetic resin, a rotating body 23 that is disposed in the casing 21 and that can rotate around the rotating shaft 22, and an output shaft 24 a that is connected to the rotating shaft 22 to rotate the rotating body 23. And a motor 24 to be driven.

  As shown in FIG. 4, the casing 21 includes three cases: a first case 25 and a second case 26 that accommodate the rotating body 23, and a third case 27 that accommodates the motor 24. The first case 25 and the third case 27 are sandwiched and fastened together. FIG. 3 is a view showing a state in which the first case 25 is removed.

  As shown in FIG. 2, recesses 25 a and 26 a are formed on the upper surfaces of the first case 25 and the second case 26, respectively. Due to the recesses 25 a and 26 a, an inlet portion 28 is formed on the upper surface of the casing 21 when a game ball guided by the guide rod 15 of the ball storage unit 11 flows into the casing 21.

  The entrance portion 28 is formed to have a width at least twice as large as the diameter of the game ball so that the game balls can flow into the casing 21 in two rows.

  The rotating body 23 includes a pair of first rotating body 23A and second rotating body 23B that are fixed to the same rotating shaft 22 and have the same shape. Hereinafter, the pair of first rotating body 23A and second rotating body 23B will be collectively referred to as a rotating body 23.

  A plurality of ball holding portions 30 capable of holding one game ball are formed at equal intervals on the peripheral surfaces of the first rotating body 23A and the second rotating body 23B. The sphere holding part 30 is formed to be recessed in an arc shape. In the present embodiment, as shown in FIG. 3, three sphere holding portions 30 are formed at intervals of 120 degrees on the peripheral surfaces of the first rotating body 23A and the second rotating body 23B.

  The first rotating body 23A and the second rotating body 23B are fixed to the rotating shaft 22 with the sphere holding portions 30 having a predetermined phase difference. In the present embodiment, the adjacent sphere holding portions 30 of the first rotating body 23A and the second rotating body 23B are fixed with a phase difference of 60 degrees (see FIG. 6).

  As shown in FIG. 3, a standby flow path 31 is formed in the first case 25 and the second case 26 to supply the game ball that has flowed into the casing 21 from the inlet portion 28 to the rotating body 23. .

  The standby flow path 31 is formed so that the axial width of the rotating shaft 22 of the rotating body 23 is at least twice the diameter of the game ball, and the game balls can be supplied to the rotating body 23 in two strips. Is done. The standby flow path 31 is formed with the downstream end facing the peripheral surface of the rotating body 23. Accordingly, when the game balls flow down the standby flow path 31 in two lines, one game ball is supplied to each peripheral surface of the first rotating body 23A and the second rotating body 23B.

  As shown in FIG. 3, the standby flow path 31 is arranged so that the rotating shaft 22 of the rotating body 23 is positioned vertically below the downstream end. Therefore, in the process of rotation of the rotator 23, the sphere holder 30 faces the downstream end of the standby flow path 31 when the opening of the sphere holder 30 faces directly upward. In the present embodiment, the rotating body 23 rotates clockwise as viewed from the direction of FIGS.

  Since the game balls exist in a daisy chain from the storage tank 14 of the ball storage unit 11 to the downstream end of the standby flow path 31, the game balls are placed on the peripheral surface of the rotating body 23 at the downstream end of the standby flow path 31. Is in a standby state. Since each of the ball holding portions 30 of the first rotating body 23A and the second rotating body 23B alternately faces the downstream end of the standby flow path 31 as the rotary body 23 rotates, the downstream of the standby flow path 31. The game balls waiting at the end are alternately accommodated in the ball holding portions 30 of the first rotating body 23A and the second rotating body 23B. Be transported.

  The game balls accommodated in the ball holding portion 30 of the second rotating body 23B are guided and conveyed by an arcuate guide 34 (see FIG. 3) formed in the second case 26. And when it faces the discharge flow path 32 formed inside the first case 25 and the second case 26, it flows out of the ball holding portion 30 by its own weight and is discharged to the discharge flow path 32. Similarly, the game balls accommodated in the ball holding portion 30 of the first rotating body 23 </ b> A are guided and conveyed by an arcuate guide 34 (not shown) formed in the first case 25, and are discharged to the discharge flow path 32. At the point of time, it flows out of the sphere holder 30 by its own weight and is discharged to the discharge channel 32.

  The game ball discharged to the discharge flow path 32 is discharged to the outside of the casing 21 through the opening 33a of the discharge sensor 33 disposed below the second case 26.

  As described above, the rotating body 23 holds the game ball waiting at the downstream end of the standby flow path 31 with the ball holding section 30, conveys it by rotation, and discharges it to the discharge flow path 32. Here, since the first rotating body 23A and the second rotating body 23B are fixed to the rotating shaft 22 with the respective ball holding portions 30 having a predetermined phase difference, the game ball is the same as the first rotating body 23A. The second rotary body 23B is alternately discharged to the discharge flow path 32. Specifically, in the first rotating body 23A and the second rotating body 23B, the ball holding portions 30 adjacent to each other are arranged with a phase difference of 60 degrees. One ball is discharged to the discharge flow path 32 every six rotations and passes through the discharge sensor 33. Therefore, the opening 33a of the discharge sensor 33 is formed to a size that allows one game ball to pass through.

  The motor 24 is disposed fixed to the back surface of the second case 26 via a fastening portion 24b (see FIG. 4) of the motor body, and the output shaft 24a is inserted through the opening 26b formed in the second case 26. Then, it is directly connected to the rotating shaft 22 of the rotating body 23 (see FIG. 5). Further, since the motor 24 is disposed so that the rear end faces the circular opening 27a for heat dissipation formed in the third case 27, the heat generated in the motor 24 is discharged through the opening 27a. . A relay board 36 that electrically connects the discharge control device 13 and the motor 24 is disposed on the side of the casing 21.

  The motor 24 is a pulse motor and is set to rotate 1/6 with N pulses. Therefore, when the discharge control device 13 is requested to discharge X gaming balls, the motor 24 receives an N × X pulse signal from the discharge control device 13. The discharge sensor 33 detects the passage of the game ball in the opening 33a, and the discharge control device 13 periodically monitors whether the number of prize balls or the number of rented balls is normal based on the detection signal.

  Next, the rotating body 23 will be described in detail with reference to FIGS. 6 is a perspective view of the rotating body 23, FIG. 7 is a front view of the rotating body 23, FIG. 8 is a side view of the rotating body 23, and FIG. 9 is a game at the downstream end of the standby flow path 31. FIG. 10 is a diagram showing a state where two balls are waiting, and FIG. 10 is a diagram showing a state where one game ball is waiting at the downstream end of the standby channel 31. The three sphere holding portions formed on the first rotating body 23A are 30A, 30B, 30C, and the three sphere holding portions formed on the second rotating body 23B are 30a, 30b, 30c. This is referred to as a sphere holding unit 30. The spherical holding unit 30 faces the downstream end of the standby flow path 31 in the order of 30A, 30a, 30B, 30b, 30C, and 30c as the rotating body 23 rotates.

  As described above, the standby flow path 31 is formed so that the axial width of the rotating shaft 22 of the rotating body 23 is at least twice the diameter of the game ball. Therefore, normally, the game balls flow down the standby flow path 31 in two strips and are supplied one by one on the peripheral surfaces of the first rotating body 23A and the second rotating body 23B as shown in FIG. At the downstream end of the standby flow path 31, two game balls (game balls indicated by reference numerals 40a and 40b in FIG. 9) are on standby. In this case, as the rotating body 23 rotates, the game balls 40a and 40b waiting at the downstream end of the standby flow path 31 are the ball holding sections 30 of the first rotating body 23A and the second rotating body 23B. Accordingly, the game balls are held by all the ball holding portions 30 of the rotating body 23.

  However, since the gaming machine 100 does not have a device for rectifying the gaming ball into two pieces in the guide rod 15 of the ball storage unit 11, as shown in FIG. There may be a state in which only one game ball (the game ball indicated by reference numeral 40c in FIG. 10) stands by, that is, a state in which the game ball is fitted in a groove between the two game balls 40d and 40e immediately above. This state is likely to occur when the supply of game balls to the discharge device 20 is started with no game balls in the discharge device 20. It may also occur when the game ball is fitted between the front two and the rear two game balls in the process of being guided from the guide rod 15 to the discharge device 20.

  In the state where only one game ball waits at the downstream end of the standby flow path 31, the game ball 40c waits near the boundary between the first rotating body 23A and the second rotating body 23B. Even when the rotating body 23 rotates and the sphere holder 30 faces the downstream end of the standby flow path 31, the sphere holder 30 may not be accommodated in the sphere holder 30. In the state of FIG. 10, the game ball 40 c must be accommodated in the ball holding portion 30 a of the second rotating body 23 </ b> B that faces the downstream end portion of the standby flow path 31 next as the rotating body 23 rotates. In some cases, the second rotating body 23B is not accommodated in the sphere holding portion 30a but is then accommodated in the sphere holding portion 30B of the first rotating body 23A that faces the downstream end of the standby flow path 31.

  Thus, in a state where only one game ball is waiting at the downstream end of the standby flow path 31, the one game ball 40c may not be stored in the ball holding unit 30 to be stored, In that case, the discharge device 20 cannot discharge the game ball as requested for discharge.

  In order to avoid such a situation, when there is only one game ball waiting at the downstream end of the standby flow path 31 on the peripheral surface of the rotator 23, the game ball is placed next in the standby flow path. A plurality of guide portions 41 for guiding to the ball holding portion 30 facing the downstream end portion of 31 are formed.

  As shown in FIGS. 6 and 8, the guide portion 41 is disposed between the ball holding portions 30 adjacent to each other of the first rotating body 23 </ b> A and the second rotating body 23 </ b> B, and extends along the circumferential direction of the rotating body 23. A depression is formed. In the present embodiment, six guide portions 41 (41A to 41F) are formed and face the downstream end portion of the standby flow path 31 in the order of 41A, 41B,.

  The guiding unit 41 rotates the second rotating body 23A and the second rotating body 23A so that the game ball waiting in the vicinity of the boundary 23a between the first rotating body 23A and the second rotating body 23B can be guided to the subsequent ball holding unit 30. It is formed from the boundary 23a with the body 23B toward the subsequent sphere holding part 30. In addition, the guide portion 41 is formed in a substantially V shape and is formed wider toward the subsequent sphere holding portion 30.

  The guide portion 41 is formed in an arc shape in cross section, and opens in an arc shape with respect to the subsequent sphere holding portion 30. By forming the cross section of the guide portion 41 in an arc shape, a trough portion 42 (see FIG. 6) that is the bottom is formed in the guide portion 41, and the trough portion 42 includes the first rotating body 23A and the second portion. It extends with a predetermined angle difference with respect to the boundary 23a with the rotating body 23B, that is, with respect to the rotating direction of the rotating body 23.

  Furthermore, the guide part 41 is formed across the boundary 23a between the first rotating body 23A and the second rotating body 23B. That is, it is formed across the circumferential surfaces of the first rotating body 23A and the second rotating body 23B.

  More specifically, the guide portion 41 is provided at a position where the V-shaped tip portion 41a approaches the preceding ball holding portion 30 side with respect to the boundary 23a, and the rear end that discharges the game ball The portion 41b opens to the subsequent sphere holding portion 30 as described above. In this way, since the guiding portion 41 is formed across the boundary 23a, the game ball waiting in the vicinity of the boundary 23a between the first rotating body 23A and the second rotating body 23B is guided as the rotating body 23 rotates. It is guided smoothly to the part 41 and guided to the subsequent sphere holding part 30.

  Here, the succeeding sphere holding unit 30 and the preceding sphere holding unit 30 indicate the two sphere holding units 30 sandwiching the guide unit 41, respectively, in the rotation direction rear side and the rotation direction front side.

  Two guide edges 41c and 41d that extend from the front end portion 41a of the guide portion 41 toward the subsequent ball holding portion 30 and guide the game ball guided to the subsequent ball holding portion 30 are formed with the first rotating body 23A and the first rotation body 23A. It is formed in a straight line so as to guide the game ball waiting in the vicinity of the boundary 23a with the two-rotor 23B to the subsequent ball holding unit 30 through the shortest path.

  In addition, the guide portion 41 is formed to be inclined downward toward the subsequent sphere holding portion 30. Therefore, the game ball is smoothly guided to the subsequent ball holding unit 30 when being guided by the guide unit 41.

  The guiding part 41 described above will be described with reference to the reference numerals shown in FIGS.

  The guide portion 41A is provided at the position where the tip end portion 41a approaches the preceding ball holding portion 30c side with respect to the boundary 23a, that is, at the second rotating body 23B, and the rear end portion 41b is formed at the first rotating body 23A. An opening is made with respect to the succeeding sphere holder 30A. Thereby, the guide unit 41A guides the game ball to the subsequent ball holding unit 30A formed on the first rotating body 23A.

  In addition, the guide portion 41B is provided at the position where the tip portion 41a approaches the preceding ball holding portion 30A side with respect to the boundary 23a, that is, in the first rotating body 23A, and the rear end portion 41b is provided in the second rotating body 23B. An opening is made with respect to the succeeding sphere holding part 30a formed in the above. Thereby, the guide unit 41B guides the game ball to the subsequent ball holding unit 30a formed in the second rotating body 23B.

  In this way, the guiding units 41 are arranged in reverse directions so that the game balls can be guided to the subsequent ball holding unit 30.

  A photoelectric sensor 37 (see FIGS. 4 and 5) is disposed in the first case 25. The photoelectric sensor 37 is formed in a concave shape, and one protrusion is a light emitting part, and the other protrusion is a light receiving part. The first rotating body 23 </ b> A is provided with six light shielding rods 38 arranged in an annular shape around the rotation shaft 22, and each light shielding rod 38 is sequentially recessed in the photoelectric sensor 37 as the rotating body 23 rotates. Pass through.

  The photoelectric sensor 37 is disposed vertically above the rotating shaft 22, and each light blocking bar 38 is disposed corresponding to each guiding portion 41A to 41F as shown in FIG. Therefore, the photoelectric sensor 37 can detect the state in which each of the guide portions 41A to 41F faces the downstream end portion of the standby flow path 31, so that the game ball is accommodated in the ball holding portion 30 based on the detection signal. The rotating body 23 can be stopped in the state immediately before the operation (the state shown in FIG. 9). Thereby, the stop position of the rotary body 23 can be controlled accurately, and it is possible to prevent extra game balls from being discharged.

  Next, the operation of the guiding portion 41 will be described mainly with reference to FIGS. FIG. 11 is a diagram showing a state in which two game balls are waiting at the downstream end of the standby flow path 31, and FIG. 12 is a view of one game ball waiting at the downstream end of the standby flow path 31. FIG. 13 is a diagram of a state in which a game ball has flowed into the ball holding unit 30. 11 to 13 are views in which the rotating body 23 is viewed from the standby flow path 31 side, that is, the rotating body 23 is viewed from directly above, and the game ball is present at the downstream end of the standby flow path 31. Show only what to do.

  First, as shown in FIG. 11, a normal case where two game balls 40a and 40b are waiting at the downstream end of the standby flow path 31 will be described. Along with the rotation of the rotating body 23, the game ball 40 b waiting on the circumference of the second rotating body 23 B is guided by the guiding portion 41 B and then faces the downstream end of the waiting flow path 31. It is accommodated in the ball holding portion 30a of 23B. Further, the game ball 40a waiting on the circumference of the first rotating body 23A is guided by the guide portion 41C, and then faces the downstream end of the waiting flow path 31, and the ball holding portion 30B of the first rotating body 23A. Is housed in.

  Thus, when there are two game balls waiting at the downstream end of the standby flow path 31, the guide unit 41 receives the two game balls waiting around the periphery of the rotating body 23. Guide along the direction and smoothly guide to the ball holding unit 30.

  Next, as shown in FIG. 12, a case where only one game ball 40c stands by at the downstream end of the standby flow path 31 and the game ball 40c is guided by the guide portion 41B will be described.

  The guide portion 41B is formed so as to cross the boundary 23a and communicate with the subsequent ball holding portion 30a. Therefore, with the rotation of the rotating body 23, the game ball 40c that stands by in the vicinity of the boundary 23a moves to the second rotating body 23B side by the guide portion 41B, and next, as shown in FIG. 31 is accommodated in the sphere holding portion 30a of the second rotating body 23B facing the downstream end portion.

  As described above, when the number of game balls waiting at the downstream end of the standby flow path 31 is one, the guide unit 41 receives the single game ball that waits for the next downstream end of the standby flow path 31. Guide to the sphere holding part 30 facing the part.

  According to the embodiment described above, the following effects can be obtained.

  Even if there is only one game ball waiting at the downstream end of the standby flow path 31, the game ball is surely transferred to the ball holding section 30 facing the downstream end of the standby flow path 31 by the guide portion 41. Therefore, the game balls are accommodated in all the ball holding portions 30 of the first rotating body 23A and the second rotating body 23B. As described above, the discharge device 20 can discharge the game ball and rectify the game ball supplied to the rotating body 23. Therefore, it is not necessary to provide a separate rectification device in the gaming machine 100. A simple structure can be obtained.

  Further, suppose that the guide portion 41 is formed so as to be raised on the peripheral surface of the rotating body 23 and guides one game ball that stands by in the vicinity of the boundary 23a by the raised shape. In this case, when the waiting game ball is guided by the guide unit, the game ball is lifted and guided by the raised guide unit. At this time, the upper game ball waiting in the standby flow path 31 is also lifted, so that a high load may be applied to the motor 24. On the other hand, in this embodiment, since the guide part 41 is formed to be recessed in the peripheral surface of the rotating body 23, when the waiting game ball is guided by the guide part 41, the game ball is the guide part. The motor 24 is not lifted up, and a high load does not act on the motor 24. Therefore, even when a single game ball waiting in the vicinity of the boundary 23 a is guided by the guiding portion 41, the motor 24 rotates stably and contributes to power saving of the motor 24.
