The game balls P flowing down the game area 6 are taken into the big prize opening 15 when each rotating member is in the first position (open state where the big prize opening is opened). The first solenoid is attached at the illustrated position (the back side of the big prize device 200), and the rotation members (in the embodiment, the first door portion 211 and the second door portion 212) rotate as will be described later. Control the drive.

  The prize winning device 200 will be described in detail with reference to the exploded perspective views of FIGS. The back surface of the base portion 201 includes the first door portion 211 (first rotating member), the second door portion 212 (second rotating member), and the third door portion 213 (third rotating member). A pivot door 210 is provided. Each of the door portions 211, 212, and 213 includes ball receiving portions 281, 282, and 283 each having a substantially flat plate shape (having a gently tapered surface), and the shaft portion 240 is rotated so that the game balls can be easily received. It can rotate as a center.

  The shaft portion 240 is provided with a shaft member 249, and the first door portion 211 (first rotating member), the second door portion 212 (second rotating member), and the third door portion 213 (third rotating member). In either case, the shaft member 249 is a common shaft. One end 249a of the shaft member 249 is inserted into the connecting hole 211s of the first door portion 211, and the shaft member 249 is passed through the loose fitting hole 213s of the third door portion 213. Then, the other end 249 b of the shaft member 249 is inserted into the connection hole 212 s of the second door portion 212. In this way, the third door portion 213 is held between the first door portion 211 and the second door portion 212.

  The shaft member 249 of the embodiment has both ends 249a and 249b having a substantially D-shaped notch in a cross-sectional view, and the connection between the first door portion 211 and the second door portion 212 is made stronger. That is, the rotation with respect to the shaft portion is restricted by the D-shaped notch so that the first door portion 211 and the second door portion 212 follow the rotation of the shaft portion. Accordingly, the first door portion 211 and the second door portion 212 are connected by the shaft member 249 (corresponding to the connecting means), and are rotated in an open state / closed state (first position / second position) in conjunction with each other. Is called. On the other hand, although the third door portion 213 shares the rotation shaft with the shaft member 249, the central position of the shaft member 249 has a circular cross section and is loosely fitted. For this reason, the 3rd door part 213 can be rotated without being restricted by rotation of the 1st door part 211 and the 2nd door part 212 (it becomes possible to move freely). If the structure which controls rotation with respect to the shaft part described above is taken, the door member to be driven with respect to the rotation of the shaft part is not bonded to the shaft part, and is driven with respect to the rotation of the shaft part. It can be used in a fixed state. In addition, it is possible to maintain a stronger fixed state than when the door member to be driven with respect to the rotation of the shaft portion is bonded to the shaft portion.

  The first door portion 211 is provided with a first opening / closing member 241 and receives the pressure of the first transmission member 243 behind. The third door portion 213 is provided with a second opening / closing member 242 and receives the pressure of the second transmission member 244 behind.

  An integrated body of the first door portion 211 and the second door portion 212 connected to the shaft member 249 and the third door portion 213 that freely moves with the shaft member (see the shaft moving body 300 in FIG. 12) is a base portion 201. By being mounted on the bearing portion 208, it becomes possible to rotate. The rear flow path member 202 is attached to the base portion 201 in order to hold the both end portions 249a and 249b. Further, the shaft portion 245 of the first transmission member 243 and the shaft portion 246 of the second transmission member 244 are mounted on the rear bearing portion 205 corresponding to each of the rear flow path members 202 and are held by the rear mounting plate 209. Reference numeral 201o is a base opening, 203 is a rear channel, 204 is an insertion portion for a winning ball count sensor, 206 is a ball entry portion, and 207 is a guidance portion.

  As can be understood from FIGS. 4 to 8 already shown, when the first door portion 211 (corresponding to the first rotating member) is in a closed state, naturally, the large winning opening 15 (base opening portion 201o) is naturally. Is closed, and the second door 212 (corresponding to the second rotating member) is also closed in the same manner as the first door 211 is closed, and the big prize opening 15 (base opening 201o) is closed. Between the first door portion 211 and the second door portion 212, a ball passage portion 215 having a size that allows at least one game ball (one ball) to pass therethrough is formed. The third door portion 213 (corresponding to a third rotating member) is a ball when the first door portion 211 and the second door portion 212 are in a closed state, and the third door portion 213 itself is also in a closed state. The passage part 215 is closed. That is, the third door portion 213 is approximately the same size as the ball passage portion.

  As shown in FIGS. 7 to 9, when at least one of the first door portion 211, the second door portion 212, and the third door portion 213 (the third door portion 213 is illustrated) is in an open state, the third door portion The ball receiving portion 283 of 213 protrudes into the game area, and the game ball P flowing down through the protruding ball receiving portion 283 can be guided to the big prize opening 15 (base opening 201o). In addition, when at least one of the first door part 211, the second door part 212, and the third door part 213 (the first door part 211 and the second door part 212 are illustrated) is in a closed state, the first door part The ball receiving surface 281 of 211 and the ball receiving surface 282 of the second door portion 212 are retracted from the game area. That is, the special winning opening 15 (base opening 201o) is partially blocked. As a result, the game ball passes through the front side 291 of the first door part 211 or the front side 292 of the second door part 212 as illustrated.

  When the first door part 211 and the second door part 212 are in a closed state, the front side 291 of the first door part 211 and the front side 292 of the second door part 212 surround the side of the ball passage part 215. Wall members are erected. A first wall member 231 is erected on the front side of the first door portion 211, and a second wall member 232 is erected on the front side of the second door portion 212. Here, each wall member has a projection length substantially the same as the projection length when the third door portion is opened. Therefore, the game ball received by the third door 213 is almost certainly guided to the base opening 201 o by the first wall member 231 and the second wall member 232.

  As shown in FIGS. 7 to 10, at least one of the first door part 211, the second door part 212, and the third door part 213 (the first door part 211 and the second door part 212 are illustrated) is in an open state. At this time, the ball receiving portion 281 of the first door portion 211 and the ball receiving portion 282 of the second door portion 212 protrude into the game area, and the game ball P flowing down through the protruded both ball receiving portions 281 and 282 is a grand prize. It can be guided to the mouth 15 (base opening 201o). In addition, when at least one of the first door part 211, the second door part 212, and the third door part 213 (the third door part 213 is illustrated) is in a closed state, the receiving surface 283 of the third door part 213 is Retreating from the gaming area. That is, the special winning opening 15 (base opening 201o) is partially blocked. As a result, the game ball passes through the front side 293 of the retracted third door portion 213 as illustrated. Thus, when the 3rd door part 213 is a closed state, the 3rd wall member 233 is standingly arranged by the both-sides edge part 293e of the front side 293 of the 3rd door part 213. FIG. Here, the third wall member 233 has a projection length substantially the same as the projection length when the first door portion 211 and the second door portion 212 are opened. Therefore, the game ball received by the first door portion 211 or the second door portion 212 is almost certainly guided to the base opening 201 o by the third wall member 233.

  Moreover, in FIG. 11, all the rotation door parts (the 1st door part 211, the 2nd door part 212, the 3rd door part 213) of the special winning opening 15 represent the open state. In this case, the ball receiving portion 281 of the first door portion 211, the ball receiving portion 282 of the second door portion 212, and the ball receiving portion 283 of the third door portion 213 protrude from the game area and draw the flowing game balls into the grand prize opening. 15 (base opening 201o) can be guided. The first, second, and third wall members 231, 232, and 233 illustrated in FIGS. 9 and 10 are the upper portions when the door portions are in a closed state. The portion is tapered. That is, the flow of the game ball is facilitated by reducing the resistance of the game ball.

  The drive mechanism for the first, second and third door portions will be described with reference to FIGS. In the integrated body (axial moving body 300) of the first door part 211, the second door part 212, and the third door part 213 attached with the shaft member 249 as a common shaft for rotation, the first door part 211 or the second door part Either one of 212 (the first door portion 211 in the embodiment) uses the shaft member 249 (shaft portion 240) as a fulcrum, and a force point when opening the first door portion 211 and the second door portion 212. A first opening / closing member 241 that protrudes is provided.

  The first opening / closing member 241 is provided so as to protrude in the inner direction of the base opening 201o on the side of either the first door portion 211 or the second door portion 212 (first door portion 211 in the embodiment) (FIG. 8). reference). Therefore, the first solenoid 251 as the first drive source is installed via the first transmission member 243 on one end side of the big prize opening 15 (base opening 201o) on the same side as the first opening / closing member 241. . A contact surface 271 is formed on the first opening / closing member 241, and the contact surface 271 is pressed by the protruding end 273 of the first transmission member 243. Accordingly, the first opening / closing member 241 is a force point, the shaft member 249 is a fulcrum, and the ball receiving portion 281 is an action point, and the lever relationship is established.

  Also in the third door portion 213, the shaft member 249 (shaft portion 240) is used as a fulcrum, and a second opening / closing member 242 serving as a power point for opening and closing the third door portion is connected via the arm portion 214. Has been provided. The second opening / closing member 242 is provided so as to protrude in the inner direction of the base opening 201o on the other side (the second door portion 212 in the embodiment) of the first door portion 211 or the second door portion 212, which is different from the above. (See FIG. 8). Therefore, the second solenoid 252 as the second drive source is installed via the second transmission member 244 on the other end side of the big prize opening 15 (base opening 201o) on the same side as the second opening / closing member 242. The A contact surface 272 is formed on the second opening / closing member 242, and the contact surface 272 receives pressure from the protruding end 274 of the second transmission member 244. Accordingly, the second opening / closing member 242 is a force point, the shaft member 249 is a fulcrum, and the ball receiving portion 283 is an action point, and the lever relationship is established.

  Since the second opening / closing member 242 is provided connected to the arm portion 214 as in the illustrated third door portion 213, the second opening / closing member is spaced from the third door portion by a necessary distance. 242 can be provided. As is apparent from the structure of the axially moving body 300, the first opening / closing member 241 and the second opening / closing member 242 are in a substantially bilaterally symmetrical positional relationship. Therefore, members involved in opening and closing movements of the doors are gathered on the left and right of the big prize opening 15 (base opening 201o). Therefore, as shown in FIGS. 6 to 8, the internal space of the special winning opening 15 (base opening 201o) can be effectively utilized. For example, the design of the rear channel 203, the winning ball count sensor insertion unit 204, the ball entering unit 206, and the guiding unit 207 is facilitated.

  The first solenoid 251 and the second solenoid 252 are provided on both sides of the big prize opening 15 (large prize winning device 200) as shown in FIGS. 4 (b) and 6, and in the closed state shown in FIG. 13 (a). The first solenoid 251 (first drive source) is turned off, and the movable iron core 255 acts (presses) on the first opening / closing member 241 via the first transmission member 243 by the spring 253 of the solenoid. The first transmission member 243 rotates about the shaft portion 245 as a rotation center by pressing of the solenoid. Then, the contact surface 271 of the first opening / closing member 241 is pushed down in response to the pressure applied to the protruding end 273 of the first transmission member. As a result, the first door portion 211 (the ball receiving portion 281) rises with the shaft member 249 as the center of rotation. As already described, since the first door portion 211 and the second door portion 212 are connected by the shaft member 249, the door portions are lifted (driven) in conjunction with each other.

  In the open state shown in FIG. 13B, the first solenoid 251 (first drive source) is turned on, the coil in the solenoid is exemplified, and the movable iron core 255 is drawn toward the solenoid. Therefore, the pressure applied to the protruding end 273 of the first transmission member 243 is released, and the contact surface 271 of the first opening / closing member 241 rises. As a result, the first door portion 211 (the ball receiving portion 281) is lowered opposite to FIG. 13A with the shaft member 249 as the center of rotation. Of course, because of the connection by the shaft member 249, the second door 212 is also lowered.

  In the closed state shown in FIG. 14A, the second solenoid 252 (second drive source) is also turned off, and the movable iron core 256 acts (presses) on the second opening / closing member 242 by the spring 254 of the solenoid. ing. The second transmission member 244 rotates about the shaft portion 246 as a rotation center by pressing of the solenoid. Then, the contact surface 272 of the second opening / closing member 242 is pushed down in response to the pressure applied to the protruding end 274 of the second transmission member. As a result, the third door portion 213 (the ball receiving portion 283) rises with the shaft member 249 as the center of rotation.

  In the open state shown in FIG. 14B, the second solenoid 252 (second drive source) is turned on, the coil in the solenoid is exemplified, and the movable iron core 256 is drawn toward the solenoid side. Therefore, the pressure applied to the protruding end 272 of the second transmission member 242 is released, and the contact surface 272 of the second opening / closing member 242 rises. As a result, the third door portion 213 (the ball receiving portion 283) is lowered opposite to FIG. 14A with the shaft member 249 as the center of rotation.

  Although solenoids have been disclosed as the first and second drive sources, the modes of excitation and demagnetization of the illustrated solenoids are appropriate. In addition to the solenoid, various electric motors can be used.

  Each of the wall members 231, 232, 233 erected on the illustrated door portions 211, 212, 213 is provided with a weight 260. The weight 260 is provided below the front surface side of each wall member when closed, and the center of gravity of each door portion is maintained on the front side of the shaft portion (shaft member) and below. For this reason, in the embodiment, when the solenoid is no longer pressed, the doors can be naturally opened. As understood from FIGS. 13B and 14B in particular, when the door is opened by the action of the solenoid, the door is quickly opened by these weights. In addition, since the opened state is maintained by the weight in the door portion once opened, the possibility of accidental opening and closing of the big prize opening due to vibration and impact is reduced. Furthermore, when the door portions 211, 212, and 213 are opened, a portion that is one side below each wall member when the door portions 231, 232, and 233 are closed contacts the base member 201. In other words, the central angle of each fan-shaped wall member is substantially the same as the opening angle of the door. Therefore, the wall member plays the role of a stick, and the durability of the door portion can be enhanced against an impact when receiving the game ball flowing down.

  The relationship between the opening aspect of each door part of the big prize opening in the ball game machine 1 of an Example and the combination of the special symbol based on a success-and-failure determination result is demonstrated. As described above, when the game success / failure determination result is a win and the combination of the special symbols displayed on the image display unit 50 of the symbol display device 43 is '6', '8', '10' A signal for exciting only the second solenoid 252 is transmitted. In this case, as shown in FIG. 9, the third door portion 213 rotates and falls, and the ball receiving portion 283 appears in the game area. Once the game ball P has come into contact with the ball receiving portion 283, the game ball P is guided to the first and second wall members 231 and 232 of the first and second door portions and is transferred to the inside of the special winning opening 15 (base opening portion 201o). It becomes easy to be moved.

  In addition, when the game success / failure determination result is a win and the combination of the special symbols displayed on the image display unit 50 of the symbol display device 43 is “0”, “2”, “4”, the first A signal for exciting only one solenoid 251 is transmitted. In this case, as shown in FIG. 10, the first door portion 211 and the second door portion 212 are rotated and lowered, and the ball receiving portions 281 and 282 appear in the game area. Once the game balls P have come into contact with the ball receiving portions 281 and 282, they are guided to the third wall member 233 of the third door portion and easily roll into the big winning opening 15 (base opening 201o).

  On the other hand, the game success / failure determination result is a win, and the combination of special symbols displayed on the image display unit 50 of the symbol display device 43 is an odd number of symbols, that is, '1', '3'. , '5', '7', '9', '11', a signal for exciting both the first solenoid 251 and the second solenoid 252 is transmitted. In this case, as shown in FIG. 11, all of the first door portion 211, the second door portion 212, and the third door portion 213 are rotated and lowered, and the ball receiving portions 281, 282, and 283 appear in the game area. The game balls P in contact with these ball receiving portions are guided to the respective ball receiving portions and easily roll into the special winning opening 15 (base opening 201o).

  As described above, when the success / failure determination result is a win, there is a difference in the ease of winning the prize winning opening 15 depending on the combination of the special symbols displayed on the image display unit 50 of the symbol display device 43. Is provided. Therefore, the player is always interested in what kind of special symbol combination it will be, and the interest of the player is further enhanced. In addition, the first game's success / failure determination result is a win, and the opening and closing of the door portion can be made different for each round according to the combination of special symbols displayed on the image display portion of the symbol display device. .

  Further, compared to a mechanism that opens and closes the big prize opening of the ball game machine by only two door portions, the degree of freedom in arrangement design of nails arranged around the big prize opening is also increased. In addition, the door portion can be driven by the two drive sources while the door portions that appear to be three at a glance are driven independently as in the embodiment.

  As another embodiment, the shaft support structure disclosed in FIGS. 15 and 16 is also possible. Specifically, the first door portion 211 (first rotating member) and the second door portion 212 (second rotating member) are connected by a beam portion 216, and both door portions open and close in conjunction. The 1st door part 211 and the 2nd door part 212 are loosely fitted by the shaft member 249, and the 3rd door part 213 is suitably fixed to the shaft member 249 used as this shaft part. In FIG. 16, the shaft member 249 serving as the shaft portion 240 is connected to the third door portion 213, but actually, the through hole 211 t of the first door portion 211 and the through hole 212 t of the second door portion 212. The through holes 213t of the third door portion 213 are arranged on the same straight line, and the shaft member 249 is inserted into each of the through holes to form the shaft moving body 300K. Therefore, the third door portion 213 can be rotated without being restricted by the rotation of the first door portion 211 and the second door portion 212 (becomes movable).

  The present invention is not limited to the embodiments, and can be implemented by appropriately changing a part of the configuration without departing from the spirit of the invention. In the embodiment, an example of application of a rotating member that is pivotally supported and rotated to a door portion used for opening and closing a special prize opening is disclosed. Therefore, it is possible to produce a variety of opening modes by providing two or more winning prize openings having the same configuration. In addition to this, it is of course possible to apply to expansion opening and reduction opening control at the start winning opening. Furthermore, the present invention can also be applied to a member such as an accessory that appropriately changes the flow path of the game ball flowing down the game area. Incidentally, although the present invention has been described using a pachinko gaming machine, it can also be applied to an appropriate gaming machine such as an arrange ball gaming machine.
