In the rotation allowance state of the ball release lever 165, the locking portion 167 is retracted from below the ball receiver 163, and the ball receiver 163 rotates from the closed state to the open state by its own weight. Each is released.

According to the said Example 3, there exist the following effects.
Since the curved middle parallel passage portion 140 is formed in each of the left sphere supply path 80 and the right sphere supply path 83, the game ball rolls in the left sphere supply path 80 and the right sphere supply path 83, respectively. In addition, the rolling speed is slowed down in the middle parallel passage portion 140. A conductive earth partition plate 136 was used as a partition between these two parallel passage portions 140. For this reason, the time required for each of the game balls in the left sphere supply path 80 and the game balls in the right sphere supply path 83 to pass through the ground partition plate 136 becomes long, and the game balls in the left sphere supply path 80 When the game balls roll in the left sphere supply path 80 and the right sphere supply path 83, the contact time in which each of the game balls in the right sphere supply path 83 and the ground partition plate 136 are in contact with each other becomes longer. Then, static electricity is reliably discharged from the game ball through the ground partition plate 136.

  Since the inclined surface 153 is provided in each of the left rib 151 and the right rib 152 of the lower partition part 132, the game balls in the left sphere supply path 80 are separated from the lower partition part 132 along the inclined surface 153 of the left rib 151. The game ball in the right ball supply path 83 and the game ball in the right ball 152 along the inclined surface 153 of the right rib 152 in a direction away from the lower partition portion 132, respectively. External force acts on the. Since the lower partition part 132 is formed integrally with the upper partition part 133, an external force acting on the lower partition part 132 from the game ball is dispersed throughout the lower partition part 132 and the upper partition part 133. For this reason, since the lower partition part 132 is prevented from shaking greatly, the game ball in the left sphere supply path 80 is stably guided along the inclined surface 153 of the left rib 151 in a direction away from the lower partition part 132. The game ball in the right ball supply path 83 is stably guided along the inclined surface 153 of the right rib 152 in a direction away from the lower partition part 132.

  Since the left rib 151 having the inclined surface 153 and the right rib 152 having the inclined surface 153 are provided in the lower partition portion 132 made of synthetic resin, when the left rib 151 and the right rib 152 are provided on the metal ground divider 136. In comparison, the manufacturing work of the left rib 151 and the right rib 152 is simplified. In addition, since the angle and the size of the inclined surface 153 can be adjusted by changing the shape of the mold, the degree of freedom in designing the inclined surface 153 is increased.

  As shown in FIG. 19, a lower partition member 170 is housed inside the main body case 40 in place of the lower partition plate 96. The lower partition member 170 has a resin partition plate 171 made of non-conductive synthetic resin and a ground partition plate 172 made of conductive metal, and the ground partition plate 172 is grounded via wiring. The earth partition plate 172 is interposed between the outlet of the upper left tray guide path 103 and the outlet of the upper right tray guide path 107 and between the outlet of the lower left tray guide path 104 and the outlet of the lower right dish guide path 108. Each of the game balls released from the left sprocket 66 and the game balls released from the right sprocket 60 comes into contact with the earth partition plate 172 immediately before being discharged to the outside of the main body case 40.

  As shown in FIG. 20, a left guide surface 173 is formed in each of the upper left plate guide path 103 and the lower left plate guide path 104 so as to be located in the entire area of the ground partition plate 172. Each of these left guide surfaces 173 guides the game ball toward the ground partition plate 172, and has an inclined shape descending toward the ground partition plate 172. A right guide surface 174 is formed in each of the upper right plate guide path 107 and the lower right plate guide path 108 so as to be located in the entire area of the ground partition plate 172. Each of these right guiding surfaces 174 guides the game ball toward the ground partition plate 172 and has an inclined shape that descends toward the ground partition plate 172.

According to the said Example 4, there exists the following effect.
An earth partition plate 172 was interposed between the outlet of the upper left tray guide path 103 and the outlet of the upper right tray guide path 107 and between the outlet of the lower left tray guide path 104 and the outlet of the lower right dish guide path 108. For this reason, since the static electricity is removed from the game balls based on the fact that the game balls come into contact with the ground partition plate 172 immediately before the game balls are discharged from the inside of the main body case 40 to the outside, Each of the game balls is prevented from being paid out in a charged state.

  A left guide surface 173 was formed at each of the outlet of the upper left dish guide path 103 and the outlet of the lower left dish guide path 104. Therefore, the game ball rolls along the left guide surface 173 toward the ground partition plate 172 in the middle of passing through each of the upper left tray guide path 103 and the lower left tray guide path 104. Will come to do. A right guide surface 174 was formed at each of the exit of the upper right dish guide path 107 and the exit of the lower right dish guide path 108. Therefore, the game ball rolls along the right guide surface 174 toward the ground partition plate 172 in the middle of passing through each of the upper right tray guide path 107 and the lower right tray guide path 108, so that the ground partition plate 172 is surely attached. Come into contact.
