An open portion 14 for the purpose is formed.

Hereinafter, the ball pulling mechanism 10 of the pachinko gaming machine 7 of this embodiment will be described in detail.
(Ball payout device 1)
The ball pulling mechanism 10 of this embodiment is formed in the ball payout device 1. The ball payout device 1 is configured to pay out the game ball B to the ball plate provided on the front surface of the pachinko game machine 7 when the game ball B fired in the game area wins in the pachinko game machine 7. There is.

As shown in FIG. 7, the ball payout device 1 is arranged on the back surface side of the main body frame (mechanical plate) 70 of the pachinko gaming machine 7. An opening hole 71 is formed in the main body frame 70 in a region facing the game board. On the back surface side of the main body frame 70, a ball tank 72 and a tank rail 73 for storing the game ball B are arranged at a position above the opening hole 71, and are connected to the tank rail 73 at a position lateral to the opening hole 71. The ball flow member 74 is arranged. The ball payout device 1 is connected to the lower end of the ball flow-down member 74.

As shown in FIG. 1, the ball payout device 1 includes a ball payout screw 4, a drive source 44 for rotating the ball payout screw 4, a ball ejection valve 3, a ball payout screw 4, a drive source 44, and a ball ejection valve 3. A case 2 for accommodating the ball and a ball detection switch 5 are provided.

(Case 2)
As shown in FIG. 1, the case 2 is formed with a ball flow path 21 through which the game ball B flows down. The ball inlet 22 of the game ball B is formed at the upper end of the ball flow path 21 in the case 2, and the ball payout outlet 23 is formed at the lower end of the ball flow path 21. In the case 2, near the ball payout outlet 23 of the ball flow path 21, a ball detection switch 5 that detects the game balls B paid out by the ball payout screw 4 one by one is arranged. The ball payout outlet 23 is formed continuously with the detection port 51 that detects the passage of the game ball B by the ball detection switch 5.

(Ball payout screw 4)
As shown in FIGS. 1 to 3, the ball payout screw 4 has a rotary shaft portion 41 directed in the vertical direction H and a spiral protrusion 42 that spirally protrudes on the outer circumference of the rotary shaft portion 41. At the lowermost position of the spiral protrusion 42, a vertical stop in which the lead angle formed in the spiral protrusion 42 in the direction of paying out the game ball B is substantially perpendicular to the axial direction of the rotating shaft portion 41. The portion 43 is formed.

As shown in FIG. 2, when the rotation of the ball payout screw 4 is stopped and the payout of the game ball B to the ball payout flow path 11 is stopped, the game ball B is placed on the vertical stop portion 43. It is in a state. The ball payout screw 4 is made of a hard nylon resin.

As shown in FIG. 1, the position detection sensor 45 arranged in the case 2 detects that the ball payout screw 4 is in the rotation stop position where the payout of the game ball B is stopped. The drive source 44 is a stepping motor, which is concentrically connected to the upper end of the ball payout screw 4. The case 2 is formed by being divided into two so as to accommodate the ball ejection valve 3, the ball payout screw 4, the drive source 44, and the like in between. FIG. 1 shows a state in which one of the cases 2 is removed.

In the present embodiment, as shown in FIGS. 2 and 3, the spiral protrusion 42 of the ball payout screw 4 is used to appropriately stop the payout of the game ball B by the ball payout screw 4 over a long period of time. The shape of the vertical stop portion 43 is devised. Specifically, the inclination angle in the vertical direction H and the radial direction R of the upper surface of the portion forming the vertical stop portion 43 of the spiral protrusion 42 changes in two stages.

In other words, on the upper surface of the portion forming the vertical stop portion 43 of the spiral protrusion 42, the upper inclined surfaces 431 and 433 and the upper inclined surfaces 431 and 433 are located below the upper inclined surfaces 431 and 433. The lower inclined surfaces 432 and 434 having an inclined angle gentler than the inclined angle of 432 and 434 are formed. The entire upper inclined surfaces 431 and 433 and the lower inclined surfaces 432 and 434 constitute the vertical stop portion 43. The inclination angle is assumed to be gentle when the angle of the ball ejection valve 3 with respect to the vertical line perpendicular to the rotation axis C1 is small, and steep when the angle with respect to the vertical line is large.

Further, as shown in FIG. 3, the upper inclined surfaces 431 and 433 and the lower inclined surfaces 432 and 434 on the upper surface of the portion forming the vertical stop portion 43 of the spiral protrusion 42 have stepped portions along the radial direction R. 430 is formed. In other words, in the vertical direction H of the ball payout screw 4, the upper inclined surface 431 of the lowermost end portion 43A forming the vertical stop portion 43 of the spiral protrusion 42 forms the vertical stop portion 43 of the spiral protrusion 42. It is located lower than the upper inclined surface 433 of the adjacent portion 43B adjacent to the lowermost end portion 43A. Further, the lower inclined surface 432 of the lowermost end portion 43A forming the vertical stop portion 43 of the spiral protrusion 42 is lower than the lower inclined surface 434 of the adjacent portion 43B forming the vertical stop portion 43 of the spiral protrusion 42. In position. The lowermost end portion 43A means a spiral portion of the spiral protrusion 42 located on the lowermost end side in the vertical direction H.

As shown in FIG. 3, in the initial setting, the ball payout screw 4 rotates in a state where the game ball B is in contact with the upper inclined surface 433 of the adjacent portion 43B forming the vertical stop portion 43 of the spiral protrusion 42. It is configured to be stopped and stop the flow of the game ball B. At the time of this initial setting, the game ball B is not in contact with the lower inclined surface 434 of the adjacent portion 43B, and a slight gap is formed between the lower inclined surface 434 and the game ball B. .. When the rotation of the ball payout screw 4 is stopped, no electric power is applied to the stepping motor which is the drive source 44, and the stop state of the ball payout screw 4 is maintained by the detent torque of the stepping motor.

Here, the ball pressure of a large number of game balls B existing on the upstream side of the game ball B placed on the upper inclined surface 433 of the adjacent portion 43B is applied. However, the ball pressure F by the game ball B placed on the vertical stop portion 43 is the rotation axis (rotation center) of the ball payout screw 4 by the vertical stop portion 43 substantially perpendicular to the axial direction of the rotation shaft portion 41. Join for C2. As a result, the torque for rotating the ball payout screw 4 hardly acts on the ball payout screw 4 from the game ball B. Therefore, the ball payout screw 4 is prevented from rotating unnecessarily, and the game ball B is prevented from being unnecessarily paid out to the ball plate.

After the pachinko gaming machine 7 is used and the upper inclined surface 433 of the adjacent portion 43B is worn by the contact with the gaming ball B, the contact point of the gaming ball B with the vertical stop portion 43 moves downward. .. At this time, the rotation of the ball payout screw 4 is stopped while the game ball B is in contact with the lower inclined surface 434 of the adjacent portion 43B.

Further, in the ball payout screw 4, the upper inclined surface 431 and the lower inclined surface 432 of the lowermost end portion 43A forming the vertical stop portion 43 of the spiral protrusion 42 are formed by the lower inclined surface 434 of the adjacent portion 43B, so that the game ball B If the flow of the game ball B is not stopped, it becomes a portion for stopping the flow of the game ball B. In other words, the upper inclined surface 431 and the lower inclined surface 432 of the lowermost end portion 43A are worn even when the upper inclined surface 433 and the lower inclined surface 434 of the adjacent portion 43B are worn by the game ball B. By moving the contact point of the game ball B to the vertical stop portion 43, it becomes a spare inclined surface capable of stopping the flow of the game ball B. As described above, in the ball payout screw 4 of the present embodiment, special measures are taken against the wear caused on the spiral protrusion 42 due to the contact of the game ball B. Therefore, the durability of the ball payout screw 4 is excellent.

Further, as shown in FIG. 2, the lower end of the metal shaft center portion 411 provided at the shaft center of the rotation shaft portion 41 of the ball payout screw 4 is provided by a bearing 29 such as a metal bush provided in the case 2. It is rotationally supported. The shaft center portion 411 is made of a material such as stainless steel. On the outer periphery of the shaft core portion 411, a sliding portion 412 that makes rotational contact with the bearing 29 together with the shaft core portion 411 is provided. The sliding portion 412 is formed of a resin such as POM having excellent slidability. The durability of the rotation of the ball payout screw 4 can be ensured by the configuration using the shaft center portion 411 and the sliding portion 412.

Further, on the outer peripheral portion of the lower end portion of the rotating shaft portion 41 of the ball payout screw 4, a covering portion 413 extending downward in the vertical direction H and covering the upper end surface of the bearing 29 and its vicinity is formed. .. By forming the covering portion 413, it is possible to prevent dust from entering the gap between the bearing 29, the shaft center portion 411, and the sliding portion 412.

As shown in FIG. 2, the spiral protrusion 42 of the ball payout screw 4 has a length that the game ball B contacts only one ball, in other words, a length of about one round in the circumferential direction S of the rotating shaft portion 41. Is formed in. With this configuration, when the ball payout screw 4 is rotated only once, only one game ball B is paid out, and when the ball payout screw 4 is used to diagnose ball breakage, ball clogging, failure, etc. In addition, this diagnosis can be made quickly.

As shown in FIGS. 2 and 4, when the flow of the game ball B is stopped by the ball payout screw 4, the game ball B is rotated on the upper surface of the vertical stop portion 43 of the spiral protrusion 42 and the ball ejection valve 3. It comes into contact with the outer peripheral surface of the main body 31 and the side wall 20 forming the spherical flow path 21 in the case 2. With this configuration, the rotation position of the ball payout screw 4 becomes the rotation stop position, so that the flow of the game ball B is stopped.

In the pachinko gaming machine 7, when the player plays a pachinko game, the ball withdrawal valve 3 is at the initial position 301. Then, when a prize is won in the game area, the ball payout screw 4 rotates, and a predetermined number of game balls B are paid out from the ball flow path 21 to the ball plate via the ball payout outlet 23. At this time, as shown in FIGS. 2 and 4, the game ball B in the ball flow path 21 is guided to the ball payout outlet 23 by the guide rib 36 formed in the rotating main body 31 of the ball pulling valve 3. .. Further, as shown in FIG. 4, the guide piece 32 of the ball withdrawal valve 3 is retracted to a position where the ball payout flow path 11 and the ball payout outlet 23 are opened. Then, the side wall portion 311 of the rotating main body portion 31 of the ball withdrawal valve 3 functions as a wall for guiding the flow of the game ball B in the ball flow path 21.

Further, when the manager or the like of the pachinko gaming machine 7 pulls out the game ball B left in the ball flow path 21 to the outside of the ball payout device 1, the manager or the like operates the operation unit 35 to move the ball pulling valve 3 to the initial position. The rotation operation is performed from 301 to the ball removal position 302. At this time, as shown in FIGS. 1 and 5, after the ball payout outlet 23 is blocked by the guide piece 32, the game ball B is pulled out from the guide piece 32 to the ball outlet 24 via the guide flow path 33. The ball removal flow path 12 to be taken out is formed. Then, the game ball B left in the ball flow path 21 is guided to the guide flow path 33 by the guide piece 32, passes through the guide flow path 33, and is taken out to the ball ejection port 24.

By the way, in the ball payout device 1, the periphery of the ball ejection valve 3 and the periphery of the ball payout screw 4 are not only the parts that the game ball B frequently contacts, but also the parts that foreign matter easily invades. Therefore, maintenance of these parts is required by the administrator of the pachinko gaming machine 7 or the like.

As shown in FIGS. 1 and 5, the ball pulling valve 3 of the ball pulling mechanism 10 is formed with an opening hole 312 as a part of the opening portion 14. The opening hole 312 is opened (exposed) to the outside of the ball payout device 1 through the opening 26 of the case 2 when the ball pulling valve 3 is rotated from the initial position 301 to the ball pulling position 302. Then, the administrator of the pachinko gaming machine 7 inserts a maintenance tool or the like into the opening hole 312 through the opening 26, and clears the ball clogging of the flow path forming portion 13 through the opening hole 312. Maintenance such as removal and cleaning of foreign matter that has entered the flow path forming portion 13 can be performed.

As a result, the manager or the like can quickly maintain the flow path forming portion 13 by operating the ball pulling valve 3 at the ball pulling position 302. Therefore, according to the ball pulling mechanism 10 in the ball payout device 1 of the game machine of the present embodiment, the maintenance of the flow path forming portion 13 can be performed quickly.

On the other hand, when the ball pulling valve 3 is in the initial position 301 and the pachinko gaming machine 7 plays a game, the opening hole 312 of the ball pulling valve 3 is in a state where the flow path forming portion 13 cannot be maintained. As a result, it is possible to prevent an unauthorized person or the like from committing an illegal act on the flow path forming portion 13 through the opening hole 312, and it is possible to take security measures.

In addition to being formed on the ball payout device 1, the ball pulling mechanism 10 can be provided on various parts and devices on which the game ball B flows down. For example, the ball removing mechanism 10 can be provided on the ball tank 72, the tank rail 73, the ball flow-down member 74, and the like.

The present invention is not limited to each embodiment, and further different embodiments can be configured without departing from the gist thereof. The present invention also includes various modifications, modifications within an equal range, and the like. Further, combinations, forms, etc. of various components assumed from the present invention are also included in the technical idea of the present invention.
