Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The gaming machine of the present embodiment is an application of the present invention to an encapsulated ball gaming machine as a pachinko gaming machine. For example, the gaming content can be the same as that of a conventional pachinko gaming machine. In addition, the size of the outer shape and the like is the same, and it can be installed in the current island facilities of pachinko amusement shops, but it does not use the ball supply mechanism or ball discharge mechanism of the island facilities Yes. That is, the enclosed ball type gaming machine uses a pre-enclosed game ball. The game sphere to be enclosed is a game sphere made of a non-magnetic material, so that illegal acts by a magnet are not performed.
In addition, the enclosed ball-type game machine can receive game value information (for example, money amount information) generated by, for example, inserting cash into a pedestrian machine (ball lending machine) or the like, and can use the game value information for games. The number of game balls (the number of game media) is converted into data on the number of possessed balls, and the game balls enclosed corresponding to this data can be launched into the game area, and when the game balls are launched, the number of game balls launched Correspondingly, the data on the number of balls is subtracted. In addition, when a game ball that has been launched wins a prize device such as various prize opening or a variable prize device and a prize ball (game ball) is generated, the actual number of balls held without paying out the actual game ball The number of prize balls is added to the data. Further, when the data on the number of possessed balls becomes 0, the game ball cannot be launched. In this state, when amount information as game value information, information on the number of stored game media, etc. are converted into data on the number of game media, the data on the number of game media converted to the data on the number of balls is added, and again Game balls can be launched.

  In other words, the enclosed ball type gaming machine is capable of playing with the number of balls held by the player, subtracting from the number of balls held by the launch, and adding to the number of balls held by winning a game ball. In addition, the released game balls reach the game area, and a part of them enter the prize area and are led to the back side of the game board and collected as safe balls, and the remaining game balls that have not been won are out. The balls are collected as spheres, and the collected game balls can be relaunched through the circulation flow path, and the game balls are circulated in the enclosed ball type gaming machine. In addition, the game ball that has become a foul is also collected in the circulation channel, and the game ball that has become a foul is collected and can be launched again without being involved in the game (without getting a chance to win a prize). Based on the occurrence of foul balls, the number of foul balls is added to the data on the number of balls held in the game value information.

  As shown in FIGS. 1 and 2, the enclosed ball type gaming machine 100 according to the present embodiment covers a machine frame 110 configured in a rectangular frame shape and a front side of the machine frame 110 and also covers the machine frame 110.

A supply ball detection sensor 246 that detects a game ball passing therethrough, and a ball supply port 247 that serves as a discharge port to the game ball launching device 60 of the supply flow path 245 (encapsulated ball circulation device 200).

  The restriction wall 241 moves to the supply flow path 245 that stops the game balls on the lowest inclination side of the game balls arranged on the inclined standby flow path 211 and causes only the game balls that have passed the restriction wall 241 to flow down to the launching device 60. It is possible. The regulation wall 241 has a height approximately equal to the radius of the game ball (the height from the upper surface of a ball holding portion 243a described later of the ball feeding member 243 positioned at the bottom), and the upper end portion is on the standby flow path 211 side. Is formed in a bent L-shaped plate shape, and the tip 241a protruding toward the standby flow path 211 comes into contact with the game ball, so that the game ball is placed in the ball receiving portion 242 (the ball holding portion of the ball feeding member 243). 243a)). The ball receiving portion 242 includes a holding portion bottom wall 248 that is joined to the restriction wall 241 at a right angle, and the restriction wall 241 and the holding portion bottom wall 248 are L-shaped.

  The ball feeding member 243 is disposed on the holding portion bottom wall 248 of the ball receiving portion 242 and includes a ball holding portion 243a for holding a game ball that has flowed into the ball receiving portion 242, and the left and right and rear sides are open. The ball holding portion forming portion 243b is formed in a letter shape (channel shape) and allows a game ball to pass from the right to the left when viewed from the back of the encapsulated ball game machine 100. The sphere holding portion 243a is a portion that becomes the bottom of the U-shaped sphere holding portion forming portion 243b.

  Further, the ball feeding member 243 has an arm portion 243c that extends in the left direction along the left-right direction (the side opposite to the side where the standby flow path 211 is formed) at the upper end portion of the ball holding portion forming portion 243b. One end portion of the arm portion 243c to which the ball holding portion forming portion 243b is not connected is rotatably engaged with an engaging portion 244a extending to the lower portion of the ball feeding electromagnet 244. Furthermore, an adsorbing piece 243d made of a material (for example, iron) capable of adsorbing the magnet is provided on the upper surface of the arm portion 243c and facing the ball feeding electromagnet 244. Further, a restricting piece 243e for restricting the downward movement of the arm portion 243c is formed in the vicinity of a portion where the arm portion 243c is engaged with a part of the ball feeding electromagnet 244.

  The arm portion 243c is configured such that the attracting piece 243d is centered on the portion engaged with the engaging portion 244a of the ball feeding electromagnet 244 by repeatedly attracting and releasing the attracting piece 243d by the ball feeding electromagnet 244. The arm portion 243c rotates in the vertical direction within a range between the position attracted by the arm portion 243c and the position where the arm portion 243c contacts the upper surface of the restricting piece 243e. Further, as the arm portion 243c rotates, the ball holding portion forming portion 243b (ball holding portion 243a) at one end of the arm portion 243c moves up and down. When the arm portion 243c is at the upper limit position in the rotation range, that is, at the position where the attracting piece 243d is attracted to the ball feeding electromagnet 244, the upper surface of the ball holding portion 243a is substantially the same as the upper end of the regulating wall 241. It is supposed to be high. Further, when the arm portion 243c is at the lower limit position in the rotation range, that is, at the position where the arm portion 243c is in contact with the upper surface of the regulating piece 243e, the upper surface on which the game ball of the ball holding portion 243a is placed is on standby. A position where the game ball can be received continuously at the downstream end of the channel 211 is set.

  From the above, the ball feeding member 243 has a position where the upper surface on which the game ball of the ball holding part 243a of the ball holding part forming part 243b is placed can receive the game ball continuously to the downstream end of the standby flow path 211. Thus, the upper surface of the ball holding portion 243a can be moved up and down between a position where the upper surface of the ball holding portion 243a is substantially the same height as the upper end of the regulating wall 241. When the ball supply device 240 is not in operation, the arm portion 243c of the ball feeding member 243 is in contact with the upper surface of the restriction piece 243e that is the lower limit in the rotation range. The game ball is stopped in a state where it is received in the ball holding portion 243a.

  Further, the upper surface of the ball holding portion 243a is inclined so as to descend from right to left when viewed from the back surface side, and flows from the standby flow path 211 onto the ball holding portion 243a of the ball feeding member 243 disposed in the ball receiving portion 242. The gaming ball is in contact with the regulating wall 241 on the side of the regulating wall 241 due to its inclination on the ball holding portion 243a. Then, as shown in FIG. 5, when the ball feeding member 243 is raised by the ball feeding electromagnet 244 and the upper surface of the ball holding portion 243 a reaches a position that is substantially the same height as the upper end of the restriction wall 241, The game ball on the holding part 243a flows down to the supply flow path 245 side over the regulation wall 241 due to the inclination of the ball holding part 243a. When one side end (the end facing the standby flow path 211) of the ball holding portion 243 a rises, the game ball to be sent to the ball feed member 243 on the standby flow path 211 next becomes the ball feed member 243. The diameter of the game ball waiting on the most downstream side of the standby flow path 211 is prevented from rising higher so as not to enter below. When the ball holding portion 243a is raised, the next game ball to be sent to the ball feeding member 243 comes into contact with one end of the ball holding portion 243a.

  Here, as shown in FIG. 4, the game ball on the ball holding portion 243a is in contact with the tip portion 241a that protrudes toward the standby flow path 211 of the regulating wall 241. It is in a state of projecting to the standby flow path 211 side from one side end (an end facing the standby flow path 211) of 243a. Therefore, as shown in FIG. 5, when the ball holding portion 243a is lifted and the game ball to be sent next to the ball feeding member 243 comes into contact with one side end of the ball holding portion 243a, the ball holding portion 243a. The game ball on the upper side is pushed upward so that the restriction wall 241 can be more easily exceeded.

  The ball feeding electromagnet 244 includes an electromagnet capable of attracting the attracting piece 243d provided on the upper surface of the arm portion 243c, and a downward extending engagement with one end of the arm portion 243c being pivotally engaged with a part thereof. Part 244a. The ball feeding electromagnet 244 is controlled in synchronization with the launching device 60 by the launching control device 63, and immediately after the launching device 60 launches the game ball, the attracting piece 243d is attracted and released to thereby dispose the ball feeding member 243. The game ball is sent to the launching device 60 by moving up and down. Since the ball feeding member 243 moves up and down so as to rotate about the engaging portion 244a, the attracting surface that attracts the attracting piece 243d of the ball feeding electromagnet 244 has a radius of a circle centered on the engaging portion 244a. It is arranged at an angle so as to substantially follow.

  The supply flow path 245 is formed on the side opposite to the side where the ball holding portion forming portion 243b is arranged with the regulation wall 241 interposed therebetween, and guides forward after the game ball has flowed almost right along the regulation wall 241. Then, the game ball is led out from the front ball supply port 247 to the launching device 60 side on the front side of the enclosed ball circulation device 200. The supply flow path 245 is provided with a supply ball detection sensor 246 that detects a game ball flowing down the supply flow path 245. Since the game ball detected by the supply ball detection sensor 246 is supplied to the launching device 60 and fired immediately after detection, the supply ball detection sensor 246 is on the front side of the launching device 60. It also serves as a launch ball sensor that detects launch.

  The ball supply device 240 as described above is configured to supply the game balls to the launching device 60 one by one by slightly raising the game balls so as to get over the regulation wall 241. Compared to a structure in which each of the sphere supply devices 240 is discharged downward one by one in a state of flowing down, many parts of the sphere supply device 240 are not arranged below the standby flow path 211, and the sphere supply Since the device 240 is located below the standby flow path 211, the vertical length of the enclosed sphere circulation device 200 can be prevented from becoming long, and the enclosed sphere circulation device 200 can be downsized. In particular, the vertical width of the enclosed ball circulation device 200 can be shortened.

  Further, the ball supply device 240 raises the game ball by the length of its diameter in order to get over the regulation wall 241, and does not lift the game ball over a long distance. The circulating path 210 of the circulation device 200 can be sufficiently accommodated within the minimum required vertical width range, and the vertical width of the sealed ball circulation device 200 can be reliably shortened. Further, the ball supply device 240 has a simple structure in which the ball feeding electromagnet 244 simply adsorbs the ball feeding member 243, and the possibility of occurrence of trouble is extremely low.

  As shown in FIG. 3, on the rear surface side of the ball supply device 240 adjacent to the downstream end of the circulation path 210 (standby channel 211), a ball removal device 230 for extracting the game ball from the encapsulated ball circulation device 200 is provided. It has been. This ball removal device 230 has a ball removal opening formed in the rear wall member 202 and a plate-like lid member 232 for opening and closing the opening. The ball opening is provided at a position facing the ball holding portion forming portion 243b of the ball feeding member 243 in the rear wall member 202, and is large enough to allow one game ball to pass. . Further, a plate-like lid member 232 for opening and closing the ball extraction opening is provided so as to be rotatable around a rotation shaft 232a so as to cover the ball extraction opening from the outside.

  Moreover, although the upper surface of the above-mentioned ball | bowl holding | maintenance part 243a inclines so that it may go down from right to left toward the back surface side, it is also the inclination which goes down back. That is, the upper surface of the sphere holding portion 243a is inclined so as to descend from the right front side to the left rear side when viewed from the back surface side of the encapsulated sphere circulation device 200. Therefore, if the lid member 232 is opened, the game ball on the ball holding portion 243a naturally flows out from the ball opening portion along the inclination. Furthermore, the game balls in the circulation path 210 also flow out to the outside so that the game balls in the enclosed ball circulation device 200 can be extracted.
