Thereby, the translucent decoration board 156 is attached to the upper opening 142 to which the passage member 147 and the rolling plate member 155 are attached so as to close the rear end portion thereof. The decorative lamp 157 arranged on the back side of the translucent decorative board 156 is turned on and blinked based on the control of the sub-integrated board 120 according to various gaming states, and the upper opening 142 is passed through the translucent decorative board 156. The interior is light-decorated.

  The translucent decorative plate 156 (free fitting attachment portion) is provided with an engagement hole 160 that engages with the engagement protrusion 154 of the passage member 147 when attached to the attachment substrate 140. The width dimension of the engagement hole 160 is set to be slightly larger than the width dimension of the engagement protrusion 154 (see FIG. 9). Therefore, the engagement between the engagement protrusion 154 and the engagement hole 160 positions the passage member 147 in the vertical direction with respect to the translucent decorative plate 156 (that is, the mounting substrate 140 to which the translucent decorative plate 156 is screwed). At the same time, movement in the rear (right direction shown in FIG. 8) is restricted, and positioning in the horizontal direction (left and right direction shown in FIG. 9) is not performed. However, the width difference (gap) between the engagement hole 160 and the engagement protrusion 154 is set to be smaller than the width difference between the engagement recess 150 and the engagement protrusion 151 described above. As a result, the passage member 147 is attached to the attachment substrate 140 with a play that can move in the left-right direction by a difference in lateral width (gap) between the engagement hole 160 and the engagement protrusion 154.

  Here, the mounting structure of the passage member 147 having the above-described play will be described. In the passage member 147 forming the guide passage 43, the engagement protrusion 151 of the passage formation portion 148 engages with the engagement recess 150 of the mounting substrate 140 in the lateral direction (left-right direction shown in FIG. 9) as described above. The mounting projection piece 153 and the engagement protrusion 154 of the plate-shaped mounting portion 149 are individually connected to the mounting cut portion 152 of the mounting substrate 140 and the engagement hole 160 of the translucent decorative plate 156, respectively. It is attached to the mounting substrate 140 by being engaged (freely fitted) with play in the direction (left and right direction shown in FIG. 9). Accordingly, when the game ball passes through the guide passage 43, the passage member 147 moves due to the flow of the game ball. That is, the attachment position of the passage member 147 on the attachment substrate 140 changes. For this reason, the relative positional relationship between the ball discharge port 43a and the cruise rolling plate 44 changes according to the flow-down mode of the game ball, and the game ball discharged from the ball discharge port 43a onto the cruise rolling plate 44. The discharge position of can be changed. As a result, it is possible to diversify the turning trajectory of the game ball on the Kroon rolling plate 44, and as a result, the visual interest in rolling the game ball is not reduced. Further, according to this configuration, the turning trajectory of the game ball can be diversified with a simple configuration in which play is provided in the attachment of the passage member 147 forming the guide passage 43.

  Moreover, the structure which diversifies the turning locus | trajectory of the above-mentioned game ball can change the time from the game ball | bowl entering the winning opening 41 to dropping the ball | bowl drop opening 44a for every turning locus | trajectory. Therefore, even if the player performs a driving operation of the game ball in anticipation of the timing at which the game ball enters the winning cutout portion 48 of the ball receiving rotator 47 constituting the ball distribution means, the game ball does not necessarily enter the winning cutout portion 48. It will not enter. That is, by diversifying the trajectory of the game ball, it is possible to prevent the game ball from hitting the winning notch 48.

  The guide passage 43 that spirally rolls the game ball as described above and drops it onto the Kroon rolling plate 44 adjusts the speed and flow direction of the game ball that has entered the winning opening 41 at various flow speeds. In this way, there is a function of rectifying a game ball to be fed onto the Kroon rolling plate 44. With such a rectifying function, there is a slight change in the discharge position of the game ball discharged on the Kroon rolling plate 44. This causes the diversification of the turning trajectory of the game ball as described above, and prevents the game ball from hitting the winning cutout portion 48.

  On the other hand, in the lower opening 143 of the mounting substrate 140 forming the lower space 45, a transparent covering plate 161 that covers the inside of the lower opening 143 (lower space 45) so as to be visible from the player side, and the transparent covering plate 161, A transparent partition plate 162 that forms a guide space 162a for a game ball sent from the ball drop opening 44a is attached to the back of the transparent partition plate 162. An attachment member 163 for attaching to the sphere and a covering member 164 covering the upper part of the ball receiving rotating body 47 are provided.

  At the center lower end portion of the transparent partition plate 162, a delivery opening 165 for feeding the game ball in the guide space 162a to the ball receiving rotor 47 disposed on the back side of the transparent partition plate 162 is formed. The delivery opening 165 has a rectangular opening shape having a width dimension of about three game balls and a height dimension of about two game balls.

  The lower surface of the guide space 162a is constituted by a part of the mounting flange portion 145 formed in the lower side portion of the lower opening 143, and gradually descends and inclines toward the center and the rear side (the ball receiving rotor 47 side). Is formed. Thereby, the game ball sent into the guidance space 162a is sent out from the delivery opening 165 to the ball receiving rotor 47 side by natural flow. In addition, a buffer protrusion piece 166 having an arc shape when viewed from the front is provided in the guide space 162a. The buffer protrusion 166 is formed integrally with the front end portion of the covering member 164 and is disposed in the guide space 162 a through a through hole formed in the transparent partition plate 162. As a result, the game balls that have fallen through the ball drop opening 44a are once received by the buffer projecting piece 166 to weaken the drop speed, and then distributed in either the left or right direction and guided to the delivery opening 165.

  In addition, operation holes 167 are formed in the transparent cover plate 161 at two left and right positions slightly outside the delivery opening 165 when viewed from the front. The operation hole 167 is a hole for eliminating ball clogging at the lower end of the guide space 162a. Specifically, when a plurality of game balls continuously enter the winning opening 41 and a ball is clogged at the lower end of the guide space 162a, an elongated rod-like operation tool is inserted into the guide space 162a from the operation hole 167. Then, by pushing in the game ball in which the ball is clogged, the ball clogging at the lower end of the guide space 162a is eliminated.

  The covering member 164 is formed of a transparent synthetic resin material, and is a decorative surface portion that comes into contact with the back surface of the transparent partition plate 162 in a portion other than the above-described buffer protrusion piece 166 and the ball receiving rotor 47 when viewed from the front. 168. On the back surface of the decorative surface portion 168, a lamp substrate 170 on which a plurality of decorative lamps 169 (light irradiation means) is mounted is attached. As a result, the decoration lamp 169 arranged on the back side of the decoration surface portion 168 is lit and blinked based on the control of the sub-integrated board 120 according to various gaming states, and the ball receiving rotator 47 is passed through the decoration surface portion 168. Light decorate the outer periphery.

  The attachment member 163 includes a bearing surface portion 171 that supports the ball receiving rotating body 47. The bearing surface portion 171 is formed in a concave shape that is slightly larger than the ball receiving rotator 47 having a disk shape, and has an inclined surface in which the back side portion is inclined upward compared to the front side portion. Along with this, the ball receiving rotator 47 is attached with the rear side portion tilted upward as compared to the front side portion, and three notches (one winning winning hole) drilled in the outer peripheral portion of the ball receiving rotator 47. The notch 48 and the two unsuccessful notches 49) are easily visible from the player side.

  As shown in FIG. 10, an insertion hole 173 through which the rotation shaft 172 of the ball receiving rotating body 47 is inserted is formed in the center portion of the support surface portion 171. The rotating shaft 172 has an upper end portion integrally attached to the center of the back surface of the ball receiving rotator 47 and is rotatably supported by a shaft support portion 173 a provided in the insertion hole 173. On the other hand, a gear 174 is integrally attached to the lower end portion of the rotating shaft 172. The gear 174 meshes with a gear 175 rotatably attached to the attachment member 163, and a drive shaft 46 a of a motor 46 serving as a drive source of the ball receiving rotating body 47 is integrally formed at the center of the gear 175. It is attached.

  Thus, when the drive shaft 46 a of the motor 46 rotates, the gear 175 rotates integrally, and the gear 174 rotates in conjunction with the rotation of the gear 175. Then, when the rotating shaft 172 to which the gear 174 is integrally attached rotates, the ball receiving rotating body 47 rotates on the inclined support surface portion 171. The drive shaft 46a of the motor 46 is always rotated in one direction after the power is turned on. Accordingly, the ball receiving rotating body 47 is always in one direction (clockwise as viewed from the player side) during the operation period. Direction).

  As described above, one winning cutout portion 48 and two defeating cutout portions 49 are formed in the outer peripheral portion of the ball receiving and rotating body 47 having a disk shape. Yes. These three notches 48 and 49 are provided at regular intervals along the outer periphery of the ball receiving rotating body 47. That is, the three notches 48 and 49 are provided at equal intervals of 120 ° obtained by dividing the entire circumference (360 °) of the ball receiving and rotating body 47 into three equal parts. Then, when any of the notches 48 and 49 is rotated to the center position of the lower end of the guide space 162a in a state where the game ball that has entered the winning opening 41 is sent into the guide space 162a, the notch is inserted into the guide space 162a. Of game balls enter. In addition, a recognition sticker that allows the player to recognize that the notch is different from the other two notches (decision notch 49) on the upper surface portion of the ball receiving rotor 47 in the vicinity of the winning notch 48. A concave portion 176 is formed for attaching a seal (a winning determination portion) with a letter “V” (not shown), for example.

  The winning cutout 48 has a cutout dimension (cutout dimension from the outer peripheral end of the ball receiving rotator 47 toward the center) substantially the same as the diameter of the game ball. On the other hand, the notch size of the dropout notch 49 is set slightly larger than the diameter of the game ball. For this reason, the game ball that has entered the unsuccessful notch 49 is gradually centered on the ball receiving rotator 47 with the rotation of the inclined ball rotator 47 (as the unsuccessful notch 49 moves upward). It is designed to move in the direction. On the other hand, the game ball that has entered the winning cutout portion 48 does not move within the winning cutout portion 48 regardless of the rotation position of the winning cutout portion 48 and is held at a fixed position.

  In addition, a winning hole 177 is formed in the upper left portion of the bearing surface portion 171 so as to have a size corresponding to one game ball, and a winning hole 178 is provided in the upper right portion of the bearing surface portion 171 for one game ball. It is drilled in the size of. The drop hole 177 is formed at a position where the distance from the rotation shaft 172 inserted into the insertion hole 173, that is, the distance from the center of the ball receiving rotating body 47 is shorter than the winning hole 178. Specifically, the winning hole 177 is formed at a position corresponding to the position of the game ball moved in the winning notch 49 with the rotation of the ball receiving rotator 47 (upward movement of the dropping notch 49). . On the other hand, the winning hole 178 is formed at a position corresponding to the position of the game ball held in the winning notch 48.

  Thus, the game ball that has entered the lost selection notch 49 gradually moves toward the center of the ball receiving rotator 47 as the ball receiving rotator 47 rotates, and the lost selection notch 49 rotates to the position of the lost selection hole 177. When you do, you enter the lost hole 177. On the other hand, since the game ball that has entered the winning cutout portion 48 is held in the winning cutout portion 48 (because it does not move toward the center of the ball receiving rotation body 47), the winning cutout portion 48 reaches the position of the dropout hole 177. Even if it rotates, it will not enter the lost hole 177. Thereafter, the game ball that has passed through the winning hole 177 enters the winning hole 178 when the winning notch 48 rotates to the position of the winning hole 178.

  A guide groove 179 is formed on the upper surface portion of the bearing surface portion 171 in the vicinity of the winning hole 177 for smoothly feeding the game ball in the winning notch 49 to the winning hole 177, and in the vicinity of the winning hole 178. A guide groove 180 for smoothly feeding the game ball in the winning cutout portion 48 into the winning hole 178 is formed on the upper surface portion of the support surface portion 171 to be.

  Further, as shown in FIG. 11, a lowering switch 181 (discharge ball detecting means) for detecting a game ball that has entered the lowering hole 177 is provided below the lowering hole 177, and below the lowering switch 181. Is provided with the above-described discharge passage 51 for collecting the game balls that have passed through the drop-off switch 181. On the other hand, a winning switch 182 (special ball detecting means) for detecting a game ball that has entered the winning hole 178 is provided below the winning hole 178, and the winning switch 182 passes below the winning switch 182. The above-described special passage portion 50 for guiding the game ball to the opening mechanisms of the first to eighth variable prize winning openings 61a to 61d and 81a to 81d is provided in communication. A command signal is output from the main control board 111 to the sub integrated board 120 (sound generation control means) based on the detection of the game ball by the winning switch 182. Based on the control of the command signal, a sound effect that causes the player to recognize that the winning game state is generated from the speakers 14 and 29 (sound generating means) is generated, so that the interest of the game is improved. It has become.

  By the way, in the structure which distributes a game ball to the special channel | path part 50 or the discharge channel | path part 51 by the ball receiving rotation body 47 demonstrated above, when a plurality of game balls are stopped in the guidance space 162a, the said plurality of game balls are taken out. It is avoided that the player is continuously guided to the special passage portion 50 to give a disadvantage to the player. That is, as described above, in a state where the winning gaming state has occurred, in other words, in a state where any one of the first to eighth variable winning ports 61a to 61d, 81a to 81d is open, When the game ball is sent into the special passage portion 50, all the variable winning ports 61a to 61d and 81a to 81d are again played when the game ball operates the opening mechanism without waiting for the opening of the variable winning port being opened. Is to be released. For this reason, if it is set as the structure which guides a some game ball to the special channel | path part 50 continuously, even if a some game ball was guide | induced to the special channel | path part 50, as a result This is the same as when the game ball is guided to the special passage portion 50 (the winning game state is generated only once), giving the player a disadvantage.

  However, according to the configuration of the present embodiment, the ball receiving rotator 47 in which the winning cutout portion 48 and the lost cutout portion 49 that are the size of one game ball are perforated in the outer peripheral portion is on the front side. A winning hole 178 for feeding the game ball that has entered the winning cutout portion 48 into the special passage portion 50 is formed in the upper portion of the bearing surface portion 171 while being attached so as to be inclined upward compared to the portion. Then, only one game ball enters the winning cutout portion 48 of the ball receiving rotator 47, and when the ball receiving rotator 47 rotates to a position (upper side) where the winning cutout portion 48 coincides with the winning hole 178, the winning is achieved. The game ball in the notch 48 is fed into the special passage 50 (winning hole 178). For this reason, even if a plurality of game balls are stopped in the guidance space 162a, the plurality of game balls are not continuously fed into the special passage portion 50 (winning hole 178), so that the player feels disadvantageous. Never give. In addition, when four game balls are stopped in the guide space 162a and the first game ball is guided to the special passage portion 50, the winning game state is generated by the first game ball, After the second and third game balls are guided to the discharge passage portion 51, the fourth game ball is again guided to the special passage portion 50, so that the variable prize opening (61 a to 61- 61d, 81a-81d) can be opened again to generate a winning gaming state.

  Next, detailed configurations of the upper variable winning ball device 60 and the lower variable winning ball device 80 will be described with reference to FIGS.

A game ball that has entered the second variable winning opening 61b is moved in the direction of the second winning ball device 92 (by the ball guiding portion 203b formed on the front structure 191 and the ball guiding portion 210b formed on the rear structure 192). A guiding path 65 for guiding to the second tulip-type winning opening 92c opening mechanism) is configured. A game ball that has entered the third variable winning opening 61c is moved in the direction of the third winning ball device 93 (by the ball guiding portion 203c formed on the front component 191 and the ball guiding portion 210c formed on the rear component 192). A guide path 66 for guiding to the third tulip-type winning opening 93c) is configured. A game ball that has entered the fourth variable winning opening 61d is moved in the direction of the fourth winning ball device 94 by the ball guiding portion 203d formed on the front component 191 and the ball guiding portion 210d formed on the rear component 192 ( A guide path 67 for guiding to the fourth tulip type winning opening 94b) is configured.

  Further, as shown in FIG. 14B and FIG. 17, a drop extending in the vertical direction is placed at the center of the rear structure 192 (between the ball guiding portions 203a and 203d and between the ball guiding portions 203b and 203c). A passage 213 is formed. An opening at the upper end of the drop passage 213 is formed as a ball inlet 213a for receiving a game ball from the special passage portion 50, and an opening at the lower end of the drop passage 213 is a ball outlet for discharging the game ball that has passed through the drop passage 213 downward. It is formed as 213b. That is, the falling passage 213 of the upper variable winning ball device 60 receives the game ball that has passed through the special passage portion 50 at the ball inlet 213a and discharges the gaming ball from the ball outlet 213b toward the lower variable winning ball device 80. On the other hand, the falling passage 213 of the lower variable winning ball device 80 receives the game ball that has passed through the upper variable winning ball device 60 at the ball inlet 213a, and enters the collection passage 232 from the ball outlet 213b (see FIG. 22B). Is discharged.

  In the drop passage 213, symmetrical opening / closing engagement members 214 are provided at two upper and lower positions between the ball guiding portions 203a and 203d and between the ball guiding portions 203b and 203c. The opening / closing engagement member 214 includes a shaft support portion 214a and is rotatably provided around the support shaft 215 by the shaft support portion 214a being rotatably supported by the support shaft 215. The left opening / closing engagement member 214 between the ball guiding portions 203a, 203d corresponds to the first variable winning opening 61a, and the right opening / closing engagement member 214 between the ball guiding portions 203a, 203d is This corresponds to the 4 variable prize winning opening 61d. On the other hand, the left opening / closing engagement member 214 between the ball guiding portions 203b and 203c corresponds to the second variable winning opening 61b, and the right opening / closing engagement member 214 between the ball guiding portions 203b and 203c is This corresponds to the third variable winning opening 61c.

  The left and right symmetrical opening / closing engagement members 214 corresponding to the upper variable winning opening (the first variable winning opening 61a and the fourth variable winning opening 61d) are respectively connected to the front structure 191 and the rear by a single support shaft 215. Similarly, each of the bilaterally symmetric opening / closing engaging members 214 corresponding to the lower variable winning opening (the second variable winning opening 61b and the third variable winning opening 61c) is also single. Are supported between the front side structural body 191 and the rear side structural body 192.

  The shaft support portion 214 a of the opening / closing engagement member 214 is disposed in a ball guiding portion (203 a to 203 d) formed in the front structure 191 and engages with the opening engagement portion 197 and the closing holding portion 198 of the opening / closing member 62. And an abutting portion 217 arranged in a drop passage 213 formed in the rear side structure 192 and abutting with a game ball falling in the drop passage 213, A bar-shaped weight 218 for adjusting the rotational balance of the opening / closing engagement member 214 around the support shaft 215 is embedded. In addition, the contact part 217 is formed as a ball receiving surface that receives the game ball at a contact part with the game ball falling through the drop passage 213. When the opening / holding state of the opening / closing member 62 is released, the bar-shaped weight 218 rotates the opening / closing engagement member 214 by its own weight, and moves the contact portion 217 from the tilting position to the standing position in the drop passage 213. .

  In addition, on the rear inner wall surface of the drop passage 213, a guide projection 213c is provided so as to receive a game ball falling in the drop passage 213 and guide it to the contact portion 217 side (front side of the drop passage 213). (See FIG. 14B and FIG. 17). The guide protrusions 213c are provided at two locations in the upper and lower sides so as to correspond to the upper and lower variable winning ports (variable winning ports 61a and 61d and variable winning ports 61b and 61c), respectively.

  Here, the opening and closing operation of the opening and closing member 62 by the opening and closing engagement member 214 and the opening and holding operation of the opening and closing member 62 by the stopper member 204 will be described. First, in the closed state of the opening / closing member 62 (variable winning openings 61a to 61d), as shown in FIG. 18B, which is a cross-sectional view taken along the line EE of FIG. The projecting portion 216 is in a state in which the engagement with the opening engagement portion 197 and the closing holding portion 198 of the opening / closing member 62 is released. However, when the opening / closing member 62 is rotated from this state by an external force such as vibration in a direction (a counterclockwise direction in FIG. 18B) that opens the variable winning opening (61a to 61d) around the support shaft 193. The closed holding portion 198 engages with the engaging protrusion 216 and restricts the rotation of the opening / closing member 62, whereby the closed state of the variable prize opening (61a to 61d) is held. That is, the opening / closing member 62 is held in a closed state with a slight play by the engagement between the closing holding portion 198 and the engaging protrusion 216.

  In the closed state of the opening / closing member 62 (variable winning ports 61a to 61d), the contact portion 217 of the opening / closing engagement member 214 is in an upright position in the drop passage 213 as shown in FIG. Further, the engagement claw 208 of the stopper member 204 engages with the holding engagement recess 199 of the opening / closing member 62 as shown in FIG. It is in a released state.

  Then, when the game ball sent from the special passage portion 50 passes through the fall passage 213 by natural fall, the game ball pushes down the contact portion 217 along with the passage, and the contact portion 217 is tilted from the standing position. Move to position. As a result, the opening / closing engagement member 214 rotates about the support shaft 215 in the clockwise direction in FIG. 18B (counterclockwise in FIG. 18C), and the engagement protrusion 216 is pushed up. As shown in FIG. 18C, which is a cross-sectional view taken along the line FF of FIG. 18A, the pushed-up engaging protrusion 216 engages with the release engaging portion 197, and as shown in FIG. The opening / closing member 62 is rotated in the clockwise direction in FIG.

  Further, when the opening / closing member 62 is rotated to the open position of the variable winning opening (61a to 61d) by the engagement of the engagement protrusion 216 and the release engagement portion 197, the HH line in FIG. As shown in FIG. 19C, which is a cross-sectional view, the stopper member 204 rotates around the support shaft 206 in the clockwise direction in FIG. 19C based on the rotation balance by the rod-shaped weight 209, and engages. The claw 208 engages with the holding engagement recess 199. Thereby, the open / close member 62 is kept open. In such an open state, the opening / closing engagement member 214 is in a state where the engagement protrusion 216 is pushed up by the closing holding portion 198 of the opening / closing member 62, and the contact portion 217 in the drop passage 213 is pushed down. Held in place.

  Thereafter, when a game ball wins the open variable winning opening (61a to 61d), the game ball flows down on the support guide surface 196 of the opening / closing member 62 and is sent to the rear (in the ball guide portions 203a to 203d). . Then, the game ball sent into the ball guiding portions (203a to 203d) pushes the ball receiving surface portion 205 backward, so that the stopper member 204 is centered on the support shaft 206 in the counterclockwise direction of FIG. 19 (B) clockwise), the engagement between the engagement claw 208 and the holding engagement recess 199 is released, and the open / close state of the opening / closing member 62 is released. At this time, the opening / closing member 62 is shown in FIG. It rotates counterclockwise at 19 (B) and closes the variable prize winning openings (61a to 61d). Accordingly, the opening / closing engagement member 214 rotates about the support shaft 215 in the clockwise direction in FIG. 19B based on the rotation balance by the rod-shaped weight 218, and the contact portion 217 falls in the drop passage 213. Move to the standing position.

  By the way, in the opening operation of the opening / closing member 62 by the opening / closing engaging member 214 described above, in the configuration of the present embodiment, the opening / closing member 62 is moved at a faster timing than the conventional configuration in which the opening / closing member is opened by the weight of the game ball. It is designed to be opened. Specifically, as shown in FIG. 20, a ball passage is constituted by a drop passage 213 that naturally drops a game ball, and a protrusion dimension L3 of the contact portion 217 in the drop passage 213 is set to a diameter dimension L2 of the game ball. Is set smaller. Then, by applying the impact force of the game ball that naturally falls in the drop passage 213 to the contact portion 217, the opening / closing engagement member 214 is rotated, and the engagement protrusion 216 and the opening / closing member of the rotating opening / closing engagement member 214 are rotated. The opening / closing member 62 is opened by the engagement with 62.

  For this reason, unlike the configuration in which the game ball is placed on the contact portion 217 and then the contact portion 217 is pushed downward by the weight of the game ball to gradually move the opening / closing member 62 to the open position. The opening / closing engagement member 214 can be rotated at the moment when a force is applied to the contact portion 217 to open the opening / closing member 62 instantaneously. As a result, the opening / closing member 62 can be opened at a quick timing. Further, according to this configuration, the ball passage (falling passage 213) in which the contact portion 217 is arranged is not an inclined passage, and the contact portion 217 is not formed in a shape larger than the game ball. Therefore, it is possible to avoid an increase in the size of the variable winning ball device (upper variable winning ball device 60, lower variable winning ball device 80), and consequently, the design freedom of the variable winning ball device is not reduced.

  Further, the drop passage 213 is set such that the passage width dimension L1 thereof is slightly larger than the diameter dimension L2 (= 11 mm) of the game ball. For this reason, the frequency with which a game ball collides with the inner wall of the fall passage 213 can be reduced, and a fall of the fall speed of the game ball can be avoided as much as possible. Therefore, the impact force caused by the natural fall of the game ball can be applied to the contact portion 217 as much as possible, and the opening / closing member 62 can be opened at a much quicker timing. The passage width dimension L1 of the drop passage 213 may be a dimension that allows one game ball to pass smoothly through the drop passage 213 without passing two game balls simultaneously. Specifically, in the embodiment, 12 mm which is 1 mm larger than the diameter dimension L2 of the game ball is set as the passage width dimension L1.

  In addition, a guide projection 213c is provided on the inner wall of the drop passage 213 so as to guide the game ball to a portion of the contact portion 217 on the shaft support portion 214a side by collision with the game ball falling through the drop passage 213. ing. Thereby, the game ball (P1 state shown in FIG. 20) entering the ball inlet 213a subsequently collides with the guide protrusion 213c in the drop passage 213 (P2 state shown in FIG. 20), and the falling direction is changed. The contact portion 217 slightly tilted from the vertical direction is switched to the direction of the shaft support portion 214a and falls to a portion on the shaft support portion 214a side (state P3 shown in FIG. 20). For this reason, the impact force of the game ball can be efficiently converted into the rotational force of the opening / closing engagement member 214 (state of P4 shown in FIG. 20), and the rotation speed of the opening / closing engagement member 214 can be increased. The opening / closing member 62 can be opened at a faster timing.

  The contact portion 217 is formed such that a contact portion with a game ball falling through the fall passage 213 is formed as a ball receiving surface for receiving the game ball, and is slightly inclined downward toward the tip side. . In other words, the contact portion 217 is disposed in the drop passage 213 so as to be in a plane perpendicular to the drop direction of the game ball colliding with the guide protrusion 213c. As a result, a game ball that has collided with the guide projection 213c and whose fall direction in the fall passage 213 is slightly inclined from the vertical direction toward the pivotal support 214a is a contact portion 217 in a direction perpendicular to the ball receiving surface. Abut. For this reason, the impact force of a game ball can be applied to the contact part 217 efficiently.

  In addition, the guide protrusion 213c is provided on the inner wall surface of the drop passage 213 facing the contact portion 217 and at a position above the position where the shaft support portion 214a is disposed. As a result, the game ball can be guided to the contact portion 217 after the game ball collides with the guide projection portion 213c, so that the game ball is sandwiched between the guide projection portion 213c and the contact portion 217. Therefore, it is possible to prevent clogging of the balls in the falling passage 213. In the embodiment, the guide projection 213c protrudes upward from the center of the shaft support 214a at a height dimension L4 (= 11.4 mm).

  Further, the projecting dimension L5 of the guiding projection 213c is determined from the path width dimension of the dropping path 213 so that it is possible to prevent the game ball from stopping on the guiding projection 213c in the falling path 213. Is set to a value smaller than the value obtained by subtracting the diameter dimension L2. Specifically, in the embodiment, the passage width dimension corresponding to the portion where the guide protrusion 213c is projected is set to 14 mm, and the value obtained by subtracting the diameter dimension L2 (= 11 mm) of the game ball from the passage width dimension Is 3 mm. Correspondingly, the projection dimension L5 of the guide projection 213c is set to 2 mm, which is smaller than 3 mm. Accordingly, the dimension L6 from the tip end portion of the guide protrusion 213c to the inner wall surface of the falling passage 213 that is opposite is 12 mm, which is larger than the diameter L2 of the game ball. As a result, the game ball is smoothly dropped on the contact portion 217 without stopping on the guide protrusion 213c.

  In the present embodiment, a material having high strength (for example, glass fiber is included) in order to prevent the opening / closing engagement member 214 from being damaged by the impact force of the game ball being applied to the contact portion 217. The opening / closing engagement member 214 is formed of polycarbonate or the like. Further, in order to increase the strength of the base of the ball receiving surface of the contact portion 217 (the portion on the shaft support portion 214a side) where the impact force of the game ball is the largest, the thick portion of the ball receiving surface is advanced from the shaft support portion 214a side. It is formed in a tapered shape that gradually narrows toward the side.

  By the way, in the opening operation of the opening / closing member 62 by the opening / closing engagement member 214 described above, the game ball flowing down the game area 12 is opened / closed at the timing when the game ball falling in the drop passage 213 contacts the contact portion 217. When the game ball passes in front of the opening / closing member 62, the opening / closing engagement member 214 (engagement projection 216) and the opening / closing member 62 (open engagement portion 197) that accompany the turning operation of the opening / closing engagement member 214 Will be hindered. In the worst case, the open / close member 62 may not be opened although the game ball passes through the drop passage 213. Therefore, the opening / closing member 62 may be reliably opened by adopting the configuration of the modification shown in FIG. Hereinafter, the configuration of the modification will be described with reference to FIG. In addition, about the same structure as above-mentioned embodiment, the same code | symbol is attached | subjected for convenience and the detailed description is abbreviate | omitted.

  As shown in FIG. 21, on the rear inner wall surface of the drop passage 213 (the inner wall that faces the abutting portion 217), a pushing projection portion 213d protrudes from a portion below the guide projection portion 213c. Yes. The pushing protrusion 213d is provided at a lower position than a shaft support 214a of an opening / closing engagement member 214 ′ to be described later, and similarly to the guide protrusion 213c, the upper and lower variable winning openings (variable winning openings 61a). , 61d and the variable prize winning openings 61b, 61c). In the embodiment, a pushing projection 213d is projected from the center of the shaft support 214a at a position of a height dimension L7 (= 3.4 mm).

  On the other hand, the open / close engaging member 214 ′ of the modified example includes a shaft support portion 214a rotatably supported on the support shaft 215, like the open / close engagement member 214, and the open / close member 62 is provided on the shaft support portion 214a. An engagement projection 216 that engages with the (open engagement portion 197 and the closing holding portion 198) and an abutment portion 217 ′ that abuts against a game ball that falls in the drop passage 213 are provided in a protruding manner. A bar-shaped weight 218 that adjusts the rotational balance of the opening / closing engagement member 214 centered on 215 is embedded. The contact portion 217 ′ of the opening / closing engagement member 214 ′ has a concave curved upper surface, and the tip portion of the contact portion 217 ′ constitutes a pressing projection 217 ′ a.

  Thus, the game ball that has collided with the guide protrusion 213c and dropped onto the contact portion 217 'is pushed down on the contact portion 217' by the subsequent downward drop, and is opened and closed in a direction to open the opening and closing member 62. The member 214 ′ is rotated. Thereafter, the game ball is pushed into the shaft support 214a side by contact with the push-in protrusion 213d, and the force for rotating the opening / closing engagement member 214 'is increased (state P5 shown in FIG. 21). Further, at this time, the pushing protrusion 217′a provided at the tip of the abutting portion 217 ′ is brought into contact with the game ball pushed by the pushing projection 213d, so that Assist in pushing. Thus, even when the game ball falls in front of the opening / closing member 62 in the closed position at the same timing as the game ball contacts the contact portion 217 ′ (P6 state shown in FIG. 21), the push-in is performed. By pushing the game ball by the protrusion 213d, the game ball in front of the opening / closing member 62 can be pushed away to open the opening / closing member (states P7 and P8 shown in FIG. 21).

  Note that the pushing protrusion 213d is in a state in which the abutting portion 217 ′ comes into contact with the game ball from the tip end portion of the pushing protrusion 213d in a state where the opening / closing member 62 has shifted to the open position (P8 shown in FIG. 21). The dimension L9 up to the contact tip portion (pushing protrusion 217′a) is provided at a position where it is slightly larger than the diameter L2 (= 11 mm) of the game ball. Thereby, pushing of the game ball by the pushing protrusion 213d can be performed more efficiently. The contact tip portion of the contact portion 217 ′ is the portion closest to the tip portion of the contact portion 217 ′ in the portion where the game ball falling through the drop passage 213 contacts the contact portion 217 ′. In the embodiment, it is the pressing convex portion 217′a at the tip of the contact portion 217 ′. In the embodiment, the dimension L9 from the tip portion of the pushing projection 213d to the abutting tip portion (pushing projection 217′a) where the abutting portion 217 ′ abuts on the game ball is 11.3 mm. A pressing projection 213d is provided. However, the protrusion dimension L8 of the pushing protrusion 213d is set to 1.8 mm.

  Next, the flow of game balls on the back of the game board 4 will be described with reference to FIG. 22A is a side view showing the ball passage cover body 220, and FIG. 22B is a cross-sectional view taken along the line II of FIG. 22A.

As shown in FIG. 22 (B), the ball passage cover body 220 receives a game ball sent to the discharge passage portion 51 of the winning distribution device 40 and collects it, and a winning distribution device. A communication passage 222 that connects the 40 special passage portions 50 and the drop passage 213 of the upper variable winning ball apparatus 60 is formed. Thus, the game balls that have been sent to the discharge passage portion 51 by sorting the ball receiving rotor 47 after entering the winning opening 41 are collected through the collection passage 221. On the other hand, the game balls that have been sent to the special passage portion 50 by sorting the ball receiving and rotating body 47 after entering the winning opening 41 pass through the communication passage 222 and fall passage 213 (ball inlet 213a) of the upper variable winning ball apparatus 60. Is sent to.

  In the vicinity of the upper variable winning ball device 60 in the ball passage cover 220, the game balls discharged from the guide path 64 (the ball discharge port 211a) are placed on the first winning ball device 91 side (the first tulip type winning port 91c). The first guiding passage 223 for guiding to the opening mechanism) and the game balls discharged from the guiding path 65 (ball discharge port 211b) are guided to the second winning ball device 92 side (opening mechanism of the second tulip type winning port 92c). And a third guide passage for guiding game balls discharged from the guide passage 66 (ball discharge port 211c) to the third winning ball apparatus 93 side (opening mechanism of the third tulip type winning port 93c). 225 and a fourth guide passage 226 for guiding the game ball discharged from the guide path 67 (ball discharge port 211d) to the fourth winning ball device 94 side (the opening mechanism of the fourth tulip type winning port 94c). The To have.

  Thus, in the open state of the upper variable winning ball device 60 (first to fourth variable winning ports 61a to 61d) accompanying the occurrence of the winning gaming state, the game ball that has entered the first variable winning port 61a 64 is sent to the first guide passage 223 and is guided to the first winning ball apparatus 91 side through the first guide passage 223 to operate the opening mechanism of the first tulip type winning opening 91c. The first tulip type winning opening 91c is opened. The game ball that has entered the second variable winning opening 61b is sent to the second guide path 224 through the guide path 65, and is guided to the second winning ball apparatus 92 side through the second guide path 224. Then, the opening mechanism of the second tulip type winning opening 92c is operated to open the second tulip type winning opening 92c. The game ball that has entered the third variable winning opening 61c is sent to the third guiding passage 225 through the guiding path 66, and is guided to the third winning ball apparatus 93 side through the third guiding path 225. Then, the opening mechanism of the third tulip type winning opening 93c is operated to open the third tulip type winning opening 93c. The game ball that has entered the fourth variable winning opening 61d is sent to the fourth guide path 226 through the guide path 67, and is guided to the fourth winning ball apparatus 94 side through the fourth guide path 226. Then, the opening mechanism of the fourth tulip type winning opening 94c is operated to open the fourth tulip type winning opening 94c. Note that the game ball that has actuated the opening mechanism of the first to fourth tulip-type prize winning ports 91c to 94c is collected through a collection passage (not marked in particular) formed in the ball passage cover body 220. .

  Further, in the lower part of the upper variable winning ball device 60 in the ball path cover body 220, there are a falling passage 213 (ball outlet 213b) of the upper variable winning ball device 60 and a falling passage 213 (ball inlet 213a) of the lower variable winning ball device 80. ) Is formed. Thus, the game ball that has passed through the drop passage 213 of the upper variable winning ball device 60 (naturally dropped) passes through the communication passage 227 and is directly dropped into the falling passage 213 (ball inlet 213a) of the lower variable winning ball device 80 by natural falling. It is sent.

  In the vicinity of the lower variable winning ball apparatus 80 in the ball path cover body 220, a game path discharged from the guide path 84 is received and collected, and a game ball discharged from the path 85 is received. A collection passage 229 for collecting the game balls, a collection passage 230 for receiving and collecting the game balls discharged from the guide passage 86, and a collection passage 231 for receiving and collecting the game balls discharged from the guide passage 87. And are formed.

  Thus, in the open state of the lower variable winning ball device 60 (the fifth to eighth variable winning ports 81a to 81d) accompanying the occurrence of the winning gaming state, the game balls that have entered the fifth variable winning port 81a 84 is sent to the recovery passageway 228 and is recovered through the recovery passageway 228. The game balls that have entered the sixth variable winning opening 81 b are sent to the collection passage 229 through the guide path 85 and collected through the collection path 229. The game balls that have entered the seventh variable winning opening 81 c are sent to the collection passage 230 through the guide path 86 and are collected through the collection path 230. The game balls that have entered the eighth variable winning opening 81d are sent to the collection passage 231 through the guide path 87 and collected through the collection passage 231.

  Further, a lower part of the lower variable winning ball apparatus 80 in the ball path cover body 220 receives a game ball discharged from the falling path 213 (ball outlet 213b) of the lower variable winning ball apparatus 80 and collects it. 232 is formed.

  As described above, according to the configuration of the present embodiment, the upper variable winning ball device 60 enters the winning port switch 63 that detects the game balls that have entered the variable winning ports 61a to 61d and the variable winning ports 61a to 61d. Guide paths 64 to 67 for guiding the game balls on the back side of the game board 4, and the guide paths 64 to 67 discharge the game balls toward the side of the upper variable winning ball apparatus 60. The winning opening switch 63 has a ball detection hole 63a for detecting the game ball based on the passage of the game ball, and the ball detection hole 63a is a passage side wall of the ball guiding portions 210a to 210d.
