Is divided into two right and left passages, a right foul ball collection passage 61 and a left foul ball collection passage 62.

  The right foul ball collection passage 61 is provided with an inclined portion 63 inclined downward and rearward at the upper portion, and the upper portion of the right foul ball collection passage 61 is inclined downward and rearward by the inclined portion 63. The lower part below extends vertically downward. The right foul ball collection passage 61 is provided with two right passage ribs 64 extending in the vertical direction. The right passage ribs 64, 64 have a rib height such that a space (passage width) sandwiched between the rear end portions of the right passage ribs 64, 64 and the front surface of the housing frame 9 is slightly larger than the diameter of the game ball. (Size) is set, so that the foul sphere flowing down in the right foul ball collection passage 61 is prevented from being exposed in the passage. The lower part of the right passage ribs 64, 64 has a height in the front-rear direction that increases rapidly toward the lower end, whereby the lower end side of the right foul ball collection passage 61 is inclined downward and rearward again.

  The left foul ball collection passage 62 is provided with two first left passage ribs 65 extending in the vertical direction, and five pieces extending in the front-rear direction on the right side surface (side surface on the collection passage 62 side) of the passage formation wall 56. The second left passage rib 66 is provided at a predetermined interval in the vertical direction. The first left passage ribs 65, 65 are such that the space (passage width) sandwiched between the rear end portions of the first left passage ribs 65, 65 and the front surface of the housing frame 9 is slightly larger than the diameter of the game ball. The height (size) of the rib is set. The second left passage rib 66 has a space (passage width) between the right end of the second left passage rib 66 and the left side surface of the collection passage partition wall 59 that is slightly larger than the diameter of the game ball. The rib height (size) is set. The first and second left side passage ribs 65 and 66 having the rib heights set in this way prevent the foul sphere flowing down in the left foul ball collection passage 62 from being exposed in the passage. The first left-side passage ribs 65, 65 increase in height in the front-rear direction as they approach the lower end, whereby the left-side foul ball collection passage 62 is inclined downward and rearward.

  The position inclined downward and rearward in the right foul ball collection passage 61 and the position inclined downward and rearward in the left foul ball collection passage 62 are set to positions shifted from each other in the vertical direction. Yes.

  Further, a lower collection passage formation wall 67 extending rightward from the lower end of the passage formation wall 56 is provided inside the passage formation member 51, and fired by the lower collection passage formation wall 67 and the lower wall portion 51c. A lower foul ball collection passage 68 is formed to connect the vicinity of the receiving port 55 of the passage 58 and the foul ball discharge recess 69 provided in the housing frame 9.

  As shown in FIG. 5, a foul ball discharge recess 69 is formed on the front surface of the storage frame 9 at a position aligned with the right and left foul ball collection paths 61 and 62 when the passage forming member 51 is attached to the storage frame 9. Is provided. The foul ball discharge recess 69 has an internal shape inclined downward and rearward in correspondence with the shapes of the right and left foul ball collection passages 61 and 62, and the lower rear portion of the foul ball discharge recess 69 is formed in the foul ball discharge passage 70. It is connected. The foul ball discharge passage 70 is formed in the housing frame 9 so as to connect the foul ball discharge recess 69 and the lower ball tray 7.

  In the foul ball collecting mechanism 50 configured as described above, the game ball launched by the game ball launching device 30 enters the passage forming member 51 from the receiving port 55, passes through the launch passage 58, and from the upper end opening 57. The game board side launch passage formed at 10 is reached. Here, since the launching strength of the game ball by the game ball launching device 30 is insufficient, the game ball (foul ball) that returns without reaching the game area of the game board 10 passes through the upper end opening 57 into the passage forming member 51. Flow into. At this time, as shown in FIG. 4, the firing passage 58 is inclined to the upper left, so that the foul sphere that has flowed into the passage forming member 51 from the upper end opening 57 is launched at a higher probability than entering the firing passage 58. It flows into a foul ball collection passage 60 formed on the left side of the passage 58. Since the upper end portion of the passage forming wall 56 and the upper end portion of the recovery passage partition wall 59 are each formed in a semicircular shape in a rear view, even if the foul ball collides with these upper end portions, It smoothly flows into one of the left foul ball collection passages 61 and 62.

  If the upper end portion of the passage forming wall 56 is formed in a tapered shape inclined downward on the foul ball collection passage 60 side, the foul ball colliding with the upper end portion is not on the firing passage 58 side but on the foul ball collection passage 60. Can be guided to the side. Further, if the upper end portion of the recovery passage partition wall 59 is formed in a tapered shape inclined downward on the right foul ball recovery passage 61 side, the game ball colliding with the upper end portion will bounce and flow into the launch passage 58. Can be prevented.

  The foul ball that has flowed into one of the right and left foul ball collection passages 61 and 62 has a passage width in each of the passage ribs so that the passage width in the collection passages 61 and 62 is slightly larger than the diameter of the game ball. Since the height is set, there is no rampage in the passage, and each of the collection passages 61 and 62 has a portion inclined downward and rearward. It flows into the foul ball discharge passage 70 from the foul ball discharge recess 69 through the foul ball collection passage, and is discharged to the lower ball tray 7 through the foul ball discharge passage 70.

  The launching strength of the game ball by the game ball launching device 30 is very weak, and the game ball that can only reach the launch passage 58 and returns to it flows into the lower foul ball collection passage 68. Then, the game ball flows into the foul ball discharge recess 69 through the lower foul ball collection passage 68 and is discharged to the lower ball tray 7 through the foul ball discharge passage 70 in the same manner as the foul ball. Thus, since the lower foul ball collection passage 68 is provided in the vicinity of the receiving port 55 of the launch passage 58, the launching strength of the game ball by the game ball launching device 30 is very weak and reaches the upper portion of the launch passage 58. No game balls can be collected quickly.

  The foul ball collection mechanism 50 configured as described above includes a passage forming member 51 that can be attached to and detached from the storage frame 9, and a foul ball discharge recess 69 and a foul ball discharge passage 70 formed in the storage frame 9. Therefore, the number of components is small, and the foul ball collection mechanism can be configured simply. Further, since the passage forming member 51 is detachable from the housing frame 9, even if a ball clogging occurs, the restoration work is easy, and the passage forming member 51 can be replaced or cleaned. Maintenance work is easy. As described above, since the maintenance work is easy, the maintenance work can be performed periodically to prevent clogging of the balls in the foul ball collection passage.

  Further, in the foul ball collection mechanism 50, the foul ball collection passage 60 is divided into two left and right passages by the collection passage partition wall 59. Therefore, even when a plurality of foul balls are generated, for example, Since the left and right foul ball collection passages 61 and 62 are divided and flow down, it is possible to prevent clogging of the balls in the foul ball collection passage. Further, since the left and right foul ball collection passages 61 and 62 each have an inclined portion whose position is shifted in the vertical direction, the flow timing of the foul balls flowing down in the left and right foul ball collection passages 61 and 62, respectively. Therefore, even when a plurality of foul balls are generated, it is possible to prevent clogging of the balls in the foul ball discharge recess 69 and the foul ball discharge passage 70 on the downstream side of the foul ball collection passage 60. Can do. In addition, since the height of each passage rib is set so that the passage width in the foul ball collection passage 60 becomes a passage width slightly larger than the diameter of the game ball, the falling foul ball may be violent in the passage. This can prevent the clogging of the balls in the foul ball collection passage. Furthermore, the impact by the falling foul ball can be absorbed by each passage rib.

  In the above-described embodiment, the pachinko machine PM has been described as an example of a bullet ball game machine provided with the foul ball collection mechanism 50. However, the present invention is not limited to this. For example, a sparrow ball game machine or an arrange ball machine The present invention can also be applied to a ball game machine such as the above.
