Description

  The present invention relates to a ball feeding unit and a gaming machine for intermittently dropping balls one by one, and more particularly to a ball feeding unit and the like whose reliability and durability are improved by a dustproof structure.

  In a gaming machine such as a pachinko machine, a ball that has been shot flows down on the surface of the game board, and in the process of flowing down, the ball rolls while colliding with a gauge (also called a nail) or impeller on the surface of the game board. The flow direction changes. As a result, if a ball wins at various winning holes arranged on the surface of the game board, a predetermined prize ball is paid out. On the other hand, if a ball flows into the out port without winning any prize hole, no prize ball is paid out. . The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the ball flowing down and expecting to win a prize and give away a prize ball.

  Such a pachinko machine has a ball feeding unit that temporarily stops the balls in the ball path and flows them down one by one. This ball feeding unit is used in, for example, a rectifier that causes a ball to flow down from a ball storage tray one by one toward a ball launching device that launches a ball onto a game board surface. Also, it may be used in a prize ball payout device that pays out while counting the number of prize balls, or may be used in a prize ball processing device that discharges while counting prize balls.

  This ball feeding unit is configured to prevent or allow the ball to flow down by reciprocally swinging the ball feeding member by a solenoid and moving the ball stopper in the ball path. Therefore, the ball feeding member is provided with a magnetic plate that is attracted to the solenoid, and the ball feeding member is reciprocally oscillated when the magnetic plate is repeatedly attached to and detached from the solenoid.

  The solenoid is attached to and detached from the magnetic plate every time one sphere is caused to flow down. Therefore, the number of attachments / detachments between the solenoid and the magnetic plate during the use period of the pachinko machine is enormous. An example in which this ball feeding unit is applied to a rectifier is disclosed in, for example, Patent Document 1.

JP 2006-141502 A

  However, since the number of attachments / detachments between the solenoid and the magnetic plate is enormous, the solenoid or the magnetic plate is worn due to the attachment / detachment, and the wear dust is generated. Further, dirt and dust adhere to the sphere itself by using the sphere for a long time, but the dirt and dust may enter the swinging central axis portion of the ball feeding member.

  In this way, when wear dust, dust, or the like enters the swinging central shaft portion of the ball feeding member, the swinging operation of the ball feeding member cannot be performed smoothly. If it does so, there exists a problem that durability of this ball feed unit falls, or the operation | movement reliability of a ball feed unit falls.

  For example, when the ball feeding unit is used in the rectifier, the ball is not stably sent to the ball launch position, resulting in variations in the ball launch intensity. When used in a prize ball payout device or a winning ball processing device, a counting error occurs, causing a problem that a predetermined number of payouts are not performed.

  The present application was made in view of the above circumstances, and by making the rocking central shaft part a dust-proof structure, its reliability and durability are improved, contributing to stable ball launch strength and reliable ball counting.

Therefore, it is possible to effectively prevent dust from entering between the shaft end portion and the shaft portion and the bearing portion, and the reciprocating swing of the ball feeding member can be always operated smoothly. The reliability and durability of the operation of the ball feeding member are improved, and it is possible to contribute to the improvement of the stability of the ball launch strength and the prevention of mistakes in ball counting.

  Since the case member is provided with a bearing portion, and the ball feeding member and the shaft portion are held therein, the ball feeding unit can be an independent unit. Therefore, it can be easily attached to and detached from a gaming machine such as a pachinko machine, and can contribute to an improvement in assembly and maintenance of the pachinko machine. It is easy to construct a shielding structure in the shaft portion, and the degree of freedom in design is improved and the reliability of each structure is also improved. The shaft portion does not come off from the bearing portion when the unit is attached or detached.

  A ball feeding unit according to another exemplary aspect of the present invention includes a ball feeding member that causes balls in a ball path to flow down one by one, a driving unit that drives the ball feeding member, and a shaft portion that pivotally supports the ball feeding member.

An adsorbing plate 23b (magnetic plate) is protruded and fixed. The ball feeding member 19 is made of a resin such as polyacetal (POM), and the suction plate 23b is made of a magnetic metal plate such as iron or nickel. Further, the suction plate 23b may be integrally formed with the ball feeding member 19.

  The ball stopper 19a advances and retreats in the ball path 25c by the reciprocating swing of the ball feeding member 19. The ball stopper 25a narrows the ball path 25c when entering the ball path 25 to prevent the ball 20 from flowing down. Allow downflow.

  The ball receiver 19b temporarily receives the ball 20 from the ball stopper 19a and sends out the ball 20 toward the ball launch position on the downstream side. That is, the ball 20 flowing down from the ball stopper 19a when the ball stopper 19a is retracted can be received once. Then, when the subsequent ball stopper 19a enters, the ball 20 once received first flows down to the downstream side and is sent out to the ball launch position.

  The shaft hole 19 c is a hole for penetrating the shaft portion 21, and is formed so as to penetrate along the width direction X of the ball feeding member 19. In the present embodiment, the shaft hole 19c and the shaft portion 21 are fitted with a clearance, and the ball feed member 19 and the shaft portion 21 are slidably rotatable.

  The shaft portion 21 is for supporting the ball feeding member 19 and is a cylindrical member made of metal such as brass or stainless steel. The shaft portion 21 is a separate member from the ball feeding member 19, and both shaft end portions 21a and 21b are held by a bearing portion 25f described later. The ball feed member 19 is reciprocally swung around the shaft portion 21 as a rotation center.

  The swinging means 23 is for reciprocally swinging the ball feeding member 19, and in the present embodiment, is configured to include a solenoid 23a and a suction plate 23b. That is, the suction plate 23b is attached to and detached from the solenoid as the energization of the solenoid 23a is turned on and off, so that the ball feed member 19 reciprocally swings.

  The solenoid 23 a and the suction plate 23 b are disposed adjacent to the ball feeding member 19 inside the case member 25. However, the case member 25 is formed with a partition wall 25n that partitions the ball feeding member 19 and the swinging means 23 (solenoid 23a and suction plate 23b), and dust generated by the swinging means 23 is generated by the ball feeding member. It is difficult to enter 19 side.

  The case member 25 has a function as a casing that encompasses the entire rectifier 16, and holds the ball feeding member 19, the swinging means 23, the suction plate 23 b, and the shaft portion 21 inside. In the present embodiment, the case member 25 is configured to be divided into a cover body 25a and a base body 25b as shown in FIG.

  4 is an external perspective view of the cover body 25a viewed from the inner surface side, and FIG. 5 is an external perspective view of the base body 25b viewed from the inner surface side.

  The cover body 25a has an inlet 25d as a part of the spherical path 25c, and the base body 25b has an outlet 25e as a part of the spherical path 25c. A ball path 25c is formed from the inflow port 25d to the discharge port 25e, and a ball stopper 19a of the ball feeding member 19 can advance and retreat in the middle of the ball path 25c.

  The sphere 20 sent from the upper plate 14 flows into the rectifier 16 from the inlet 25d. And it discharges | emits intermittently from the discharge port 25e one by one through the ball | bowl path | route 25c via the ball | bowl feeding member 19. FIG. The discharged sphere 20 flows down to the sphere launch position and is bulleted by the sphere launcher.

  A first lid portion 25g and a second lid portion 25h as a part of the bearing portion 25f are formed below the inlet 25d in the cover body 25a (in the direction of arrow Z in FIG. 4). On the other hand, a first holding portion 25i and a second holding portion 25j as a part of the bearing portion 25f are formed below the discharge port 25e in the base body 25b (in the direction of arrow Z in FIG. 5).

  The first shaft end portion 21a of the shaft portion 21 is held by the first holding portion 25i, and the second shaft end portion 21b of the shaft portion 21 is held by the second holding portion 25j. Then, when the cover body 25a and the base body 25b are assembled in an overlapping manner, the first lid portion 25g and the second lid portion 25h are superimposed on the first holding portion 25i and the second holding portion 25j, respectively, and the shaft portion 21 Both shaft end portions 21a and 21b are substantially sealed.

  That is, the first holding portion 25i and the first lid portion 25g are fitted in a state where the first shaft end portion 21a is held in the concave portion of the first holding portion 25i. Then, the outer peripheral portion of the first shaft end portion 21a is entirely sealed by the concave portion of the first holding portion 25i and the first lid portion 25g. In addition, the side end portion of the first shaft end portion 21a is sealed by a shielding wall 25k and a first lid portion 25g described later.

  Similarly, the second holding portion 25j and the second lid portion 25h are fitted in a state where the second shaft end portion 21b is held in the concave portion of the second holding portion 25j. Then, the outer peripheral portion of the second shaft end portion 21b is entirely sealed by the recessed portion of the second holding portion 25j and the second lid portion 25h. In addition, the side end portion of the second shaft end portion 21b is hermetically sealed by the standing wall 25p and the second lid portion 25h that stand on the side end portion of the second holding portion 25j.

  At this time, as shown in FIG. 2, the vicinity of the center of the shaft portion 21 is covered with the ball feeding member 19. Since both shaft end portions 21a and 21b of the shaft portion 21 are covered with the bearing portion 25f, the shaft portion 21 is entirely sealed by the cooperation of the ball feeding member 19 and the bearing portion 25f.

  The first holding portion 25i has a shielding wall 25k erected on the swinging means 23 side so as to cover the first shaft end portion 21a. The shielding wall 25k separates the ball feeding member 19 and the swinging means 23 disposed adjacent thereto, so that dust or the like from the swinging means 23 enters the ball feeding member 19 side, that is, the shaft portion 21 side. Is preventing. In the present embodiment, the shaft portion 21 is substantially sealed by the ball feeding member 19 and the bearing portion 25f. However, if the shielding wall 25k is provided even if the shaft portion 21 is not a sealed structure, the shaft portion 21 may be shaken. An effect of preventing dust from the moving means 23 from entering the shaft portion 21 side can be exhibited.

  In the vicinity of the first lid portion 25g of the cover body 25a, a partition lid 25l is erected along the vertical direction. On the other hand, a partition plate 25m is erected in the vicinity of the first holding portion 25i of the base body 25b along the vertical direction. When the cover body 25a and the base body 25b are overlapped and assembled, the partition lid 251 and the partition plate 25m are in close contact with each other, and cooperate to form the partition wall 25n. The partition wall 25n separates the ball feeding member 19 and the swinging means 23 in the case member 25. Accordingly, dust and the like from the swinging means 23 side is blocked more firmly, and entry into the ball feeding member 19 side is effectively prevented.

  The rectifier 16 causes the balls from the upper plate 14 to flow down one by one to the ball launching position by the ball feeding member 19. The ball feeding operation is realized by the ball feeding member 19 reciprocatingly swinging around the shaft portion 21 due to the attaching / detaching operation of the suction plate 23b by the solenoid 23a. Dust is generated from the solenoid 23a or the suction plate 23b by the repeated mounting / removing operation by the solenoid 23a, but the shaft portion 21 is separated from the solenoid 23a side and the ball feeding member 19 side by the shielding wall 25k and the partition wall 25n. It is possible to effectively prevent dust from entering the side.

  Further, since the shaft portion 21 is substantially sealed by the ball feeding member 19 and the bearing portion 25f, it is possible to prevent the intrusion of dust even more strongly, and the intrusion of dirt, dust, etc. dropped from the ball 20 is also effective. Can be prevented.

  The ball launching device (not shown) is for firing (bulleting) the ball 20 sent out by the rectifying device 16 and stopped and held at the ball launching position toward the upper part of the game area 6b. The ball launching device energizes, for example, a launcher that launches the ball 20 sent to the launch position toward the game area 6b, a launch motor that drives the launcher to reciprocate the launcher, and a launcher. The unit is configured to have a firing spring or the like that generates a force for the ball and is attached to the machine casing 8.

  The firing handle 17 is a handle for adjusting the strength of the bullet ball by the ball launching device, and is operated by the player by hand. For example, it is arranged on the lower right side of the front surface of the pachinko machine 2 and has a substantially cylindrical shape, and its strength adjusting rod 17a is rotatable along the circumferential surface of the cylinder. The player can adjust the firing strength of the ball 20 by rotating the strength adjusting rod 17a while holding the firing handle 17 by hand.

  The reliability of the ball feeding operation by the rectifying device 16 is improved, and the ball 20 is stably stopped and held at the ball launch position, so that the ball launch intensity is stabilized. Therefore, the player can easily hit the ball 20 at the aimed position. It is not necessary to make a fine correction of the firing intensity by frequently rotating the firing handle 17 so that the ball firing intensity does not vary.

  In the above embodiment, the ball feeding member 19 and the shaft portion 21 are separate members, and the shaft portion 21 is fitted in the shaft hole 19c of the ball feeding member 19, but of course as shown in FIG. Alternatively, the ball feeding member 19 and the shaft portion 21 may be integrated, and the ball feeding member 19 and the shaft portion 21 may always be rotated.

  In this case, the sliding rotation between the shaft portion 21 and the bearing portion 25f is increased as compared with the above embodiment, but dust and dust intrusion from the swinging means 23 and the ball 20 are effectively prevented. Therefore, the reliability and durability of the rectifier 16 are improved.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary. For example, as described above, it is of course within the scope of the present invention that the ball feeding unit according to the present invention is applied not to the rectifier but to a prize ball payout device or a winning ball processing device. In this case, the ball feeding member may be a sprocket, and the driving means may be a motor that rotationally drives the sprocket.
