That is, the sorting device disclosed in Patent Document 1 is provided with two permanent magnets in a rotating part having a first ball receiving part and a second ball receiving part, and the rotating part is rotated by the weight of the ball. In addition, a permanent magnet opposed to the magnet is provided on the front cover, and the posture of the rotating portion is maintained by the attractive magnetic force.
In addition, the sorting device disclosed in Patent Document 2 is provided with an inverted T-shaped sorting piece that is rotatable directly below the safe ball inlet, and rotates the sorting piece according to the weight of the safe ball. It was designed to be distributed alternately to the ball socket.

  By the way, in the sorting device shown in Patent Document 1 or Patent Document 2, there is a defect that if the next ball flows in during the rotation of the rotating body, the ball is likely to be clogged, and the impact of the ball is always the sorting piece. The disadvantage of being easily damaged because it is added to the tip of the material, and the sorting device shown in Patent Document 1 requires a plurality of permanent magnets as component parts, which requires a large number of required parts and takes time to assemble, resulting in high manufacturing costs. There was a problem.

The present invention is to solve the above-mentioned problems, and the invention of the game ball sorting apparatus according to claim 1 includes a case member in which a ball passage that branches to the left and right sides is formed below the ball inlet, The swing member is pivotally supported in the case member so as to be able to tilt left and right in a pendulum manner so that the center of the upper surface is directly below the branch portion of the ball passage. It has a wall surface and a bottom surface that is formed in a symmetrical low mountain shape, and a weight ball is accommodated in the swing member so as to be able to move to the left and right over the mountain, according to the position of the weight ball. The swinging member is maintained in one of the left and right tilting postures, and the game ball dropped on the upper surface of the swinging member is guided to one of the left and right ball paths according to the tilting posture, and the left and right ball In the passage, there is an invitation for the game ball to collide with the wall surface of the rocking member. Parts are formed, wherein the game ball weight ball by impact when the game ball collides with the wall surface is flowing from the bulb inlet port by moving has to be distributed to the right and left.
The invention described in claim 2 is characterized in that, in the game ball sorting apparatus, a step portion is formed at the ball inlet, and the game ball falls onto the upper surface of the tilting body through the step portion. .
According to the third aspect of the present invention, the ball flow path of the same game ball sorting device is connected to the ball flow outlets of the right and left ball passages in the game ball sorting device, so that more game balls can pass through the ball path. It is characterized in that it can be distributed to.

  The game ball sorting apparatus according to the present invention has a simple configuration and is less likely to cause clogging or damage.

  Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view of the game ball sorting apparatus, and FIG. 2 is a longitudinal sectional view thereof. Reference numeral 1 denotes a case member formed of transparent plastic. A ball inlet 2 is formed at the upper center of the case member, and the ball passages 3a and 3b branch to the left and right sides at a branch portion 3 below the ball inlet. Are formed symmetrically. 4 is a step formed in the spherical inlet 2, and by forming the step, the spherical inlet 2 is formed in a side crank shape as shown in FIG. The game ball that has flowed into the vehicle once falls into the stepped portion and then falls further down. As will be described later, guide portions 6a and 6b are formed on the inner wall surfaces of the ball passages 3a and 3b. The extreme ends of the ball passages 3a and 3b are connected to the ball outlets 5a and 5b, respectively.

  Reference numeral 10 denotes a symmetrical box frame-like rocking member, which is pendulum-shaped by a support shaft 11 at the center in the case member 1 so that the center of the flat upper surface 12 of the rocking member is directly below the branching portion 3. It is pivotally supported so that it can be tilted left and right. The oscillating member 10 has wall surfaces 13a and 13b on both the left and right sides, and the bottom surface 14 is formed in a low symmetrical left and right ridge shape. A weight ball 15 is accommodated in the swing member 10 so as to move over the mountain and move left and right. In addition, drooping pieces 16 a and 16 b are formed on both sides of the lower portion of the swing member 10, and the drooping pieces are hung from an opening 7 formed at the center of the bottom of the case member 1, and are formed on both side edges 7 a and 7 b of the opening 7. The hanging pieces 16a and 16b function as stoppers when the hanging pieces hit, and the tilt angle α (tilt angle from the horizontal plane) is regulated to an angle of about 5 degrees at which the game ball can roll. Therefore, when the weight sphere 15 is located on the left wall surface 13a of the swing member 10 as shown by a solid line in FIG. 2, the swing member 10 is inclined to the left by its gravity. The upper surface 12 is kept inclined to the left. Further, when the weight sphere 15 is located against the right wall surface 13b, the swinging member 10 assumes a right inclination posture as shown by a broken line in FIG. 2, and the upper surface 12 is inclined to the right. Maintained.

  Therefore, as shown in FIG. 4A, when the game ball P falls on the upper surface 12 from the ball inlet 2 when the swinging member 10 is in the left inclined posture, the game ball It rolls to the left according to the inclination and flows into the spherical passage 3a, curves along the arcuate guide portion 6a formed on the inner wall surface of the spherical passage 3a, and swings as shown in FIG. After colliding with 10 wall surfaces 13a, it flows out to the spherical outlet 5a. Due to the impact, the weight sphere 15 is pushed out, and the weight sphere 15 climbs over a low mountain on the bottom surface 14, leans against the wall surface 13b and stops, so that the swinging member 10 is moved to the right as shown in FIG. The inclined posture is maintained.

  Next, as shown in FIG. 5D, when the game ball P falls on the upper surface 12 from the ball inlet 2 when the swinging member 10 is in the right inclined posture, the game ball is inclined. To the right and flow into the spherical passage 3b, curve along the arcuate guide portion 6b formed on the inner wall surface of the spherical passage 3b, and as shown in FIG. And then flows out to the ball outlet 5b. The weight sphere 15 is pushed away by the impact, and the weight sphere 15 gets over the lower mountain on the bottom surface 14 and leans against the wall surface 13a to stop. For this reason, the swinging member 10 returns to the left inclined posture as shown in FIG. For this reason, when a game ball flows in again from the ball inflow port 2, the game ball flows out from the ball outflow port 5b as shown in FIG. As described above, in this sorter, the game balls flowing into the ball inlet 2 can be alternately distributed to the two ball outlets 5a and 5b.

In this embodiment, the guide portions 6a and 6b are formed in an arcuate shape. However, this is intended to maintain a constant speed at which the game ball collides with the wall surfaces 13a and 13b. However, it may be formed in other curved or linear shapes.
As described above, in this game ball sorting device, the game balls P roll in the tilt direction of the upper surface 12 of the swing member 10 and are alternately sorted. Therefore, there is very little possibility that the balls will be clogged at this sorting portion. The game ball rolls freely and is always distributed smoothly without any fear of applying unnecessary force.

  In addition, a step 4 is provided at the ball inlet 2 so that the game ball flowing down from the ball inlet 2 once hits the step 4 and then drops onto the upper surface 12 so that the velocity of the game ball flowing in is reduced. Further, since the ball pressure is reduced by the stepped portion and an unnecessary load is not applied to the upper surface 12, a smoother distribution operation can be expected.

  This device can be provided directly on the game board surface of the pachinko machine, or can be provided inside a prize-winning device or an accessory, as well as a game machine using a pachinko ball such as an arrange ball machine or a sparrow ball machine as a game medium. It is provided and used appropriately to change the winning path and to control the winning rate.

  On the other hand, in FIG. 6, the six game ball sorting devices 100 to 600 as described above are arranged in a three-stage pyramid shape, and the middle stage sorting devices 200 and 300 are arranged at two ball outlets of the upper sorting device 100. Are connected to one of the ball outlets of the sorting device 200, the ball inlet of the lower sorting device 400 is connected to the other ball outlet of the sorting device 200, and one of the ball flows of the sorting device 300. The ball inlet of the lower sorting device 500 is connected to the outlet, the ball inlet of the lower sorting device 600 is connected to the other ball outlet of the sorting device 300, and flows into the ball inlet Y of the upper sorting device 100. The game balls thus made flow out of any one of the ball outlets A to D of the lower sorting devices 400 to 600. By connecting in this way, the game balls are placed in a predetermined order. The probability that a game ball that has flowed into the ball inlet Y can flow out of the ball outlet A is 1/8, and that of the ball outlet B is 3/8. The probability of flowing out from the ball outlet C is 3/8, and the probability of flowing out from the ball outlet D is 1/8. Thus, by connecting the sorting devices in multiple stages, the game balls can be sorted more finely, and the sorting order and probability can be set as expected.
