To greatly reduce the number of game balls to be prepared and to eliminate the need for various facilities for handling game balls outside the game machine provided in island facilities and the like. On the other hand, there is a new system that collects all game balls fired from the launcher toward the game board surface and guides them directly to the launcher, counts the number of winning balls, etc., and sequentially presents the necessary information to the player. Ball manipulation and detection mechanisms are required. In addition, a new ball management mechanism is required to acquire information necessary for cleaning due to dirt on enclosed game balls, and to detect clogging of game balls on the circulation path.

Here, one of the objectives of the managed gaming machine is to reduce access from the outside to the game balls sealed inside the gaming machine as much as possible. Therefore, in order to reduce the processing itself that requires access to the game balls, the game balls are reliably circulated without causing clogging inside the game machine, and maintenance such as cleaning the dirt on the game balls is automatically performed. Mechanisms have been proposed that allow this to be done inside game machines.

For example, Patent Literature 1 discloses a ball circulation device for an enclosed game machine that returns game balls shot from a shooting device to the shooting device. Game balls are circulated from the out port, the winning port and the foul port to the shooting device through a circulation gutter, and a dirt removing device equipped with a brush for removing dirt on the surface of the game ball is provided on the path. Also, there is provided a conveying device for conveying the game ball horizontally to the shooting device without gravity falling. These devices are mounted on the front side of the front frame that is hinged to the outer frame, and do not open the front frame. can be performed, and maintainability is improved. In addition, since the game balls are held and moved by the conveying device using the screw without gravity falling, it is possible to effectively prevent ball clogging while cleaning the game balls with the brush.

In addition, regarding the exchange of the game balls enclosed inside the game machine, after the game balls in use are accommodated in the detachable ball exchange cassette provided in the circulation path, the balls are exchanged with new game balls. A method has also been proposed that enables replacement without direct access to the game balls by replacing them with a cassette. Furthermore, if an illegal ball is mixed with a game ball, it will be difficult to detect it from the outside after the game ball is enclosed in the game machine, so a mechanism for detecting this inside the game machine has been proposed. there is

As shown in FIG. 1, the ball shooting/recovery unit 1 is attached to the back frame main body 2 from the back side of the game board (not shown), and is partially penetrated to the front side. The game board is arranged to be flush with the front side surface of the stepped portion 2a of the back frame main body 2 and the rear side surface of the discharge outlet 109 with the game board surface facing forward. A receiving opening 11 for receiving out balls and winning balls led to the back side of the game board is opened in the upper part of the ball shooting/collecting unit 1. - 特許庁Here, the ball shooting/recovery unit 1 is used in an enclosed game machine (management game machine) that encloses and circulates game balls. That is, the ball shooting/recovery unit 1 can receive game balls from the game board surface through the receiving opening 11, shoot the game balls from the shooting outlet 109 to the game board surface through the shooting passage, and circulate the game balls. By adopting the enclosed type, the total number of game balls can be reduced, so the unit price is allowed to rise, and non-magnetic stainless steel balls are used instead of iron balls for the purpose of fraud prevention.

Referring also to FIG. 2 , the ball shooting/retrieving unit 1 has a front door 3 on the front side, and a shooting section 100 inside the front door 3 . The shooting part 100 stores the game ball B discharged from the shooting ball loading port 101 on the shooting rail 104 with the ball stopping piece 102, and hits the game ball B with the hammer 103 to shoot the game ball B from the shooting rail 104 to the upper left. It can be shot toward the game board surface through the shooting passage up to the exit 109. - 特許庁A ball loading port 101 is provided with a sensor such as a proximity switch for detecting game balls, and game balls stored on a launch rail 104 can be detected to count the number of game balls loaded into the launching section 100 . A second firing rail 105 following the firing rail 104 is attached to the rear surface of the front door 3, and is continuous with the firing rail 104 and the third firing rail 106 when the front door 3 is closed. It is made to be eggplant. At the tip of the third shooting rail 106, there is provided a foul ball recovery port 111 which receives the return ball (foul ball) of the game ball which has been shot and failed to reach the game board surface, and is opened upward. The foul ball recovery port 111 is connected to a return ball inclined passage 112 so as to guide return balls to an outlet 112a, which will be described later. In addition, the return ball inclined passage 112 is provided with a sensor (not shown) such as a proximity switch, so that the return balls can be counted. The ejection outlet 109 is provided with an ejection outlet blocking piece 122 . The ejection outlet blocking piece 122 will be described later.

A front door extension 3a extending downward is provided on the lower right side of the front door 3 to block an illegal ball discharge port 29, which will be described later. On the other hand, the ball shooting/retrieving unit 1 is provided with a ball extraction button 121, a ball extraction passage outlet 128, and a ball extraction passage door 129 at positions not hidden by the closed front door 3, and the ball extraction is performed with the front door 3 closed. can be done. The details of such ball extraction will be described later.

Referring to FIG. 3, a ball receiving portion 10 provided with a receiving opening 11 is connected to an illegal ball sorting portion 20 as a path for game balls. Further, the irregular ball sorting section 20 is connected to the lower ball gutter 30 to form a main inclined passage leading from the receiving opening 11, and is connected to a ball feeding section 40 including a rotating disk 41 (see FIG. 8). The ball feeding portion 40 is connected to the discharge end portion 51b of the introduction passage 51 (see FIG. 8) of the ball rising portion 50 for lifting the game ball. Also, the ball-rising part 50 is connected to the launching part 100 via an upper-layer ball gutter 90 (see also FIGS. 8 and 11) that serves as a launching part passage.

As shown in FIG. 4, the ball receiving portion 10 has a receiving opening 11 which is widened so as to be connected to the path of out balls and winning balls led to the back side of the game board. A stepped passageway 12a and 12b is provided to align received game balls to pass a passing sensor 13 comprising a downstream proximity switch. The downstream of the passing detection sensor 13 is connected to the illegal ball sorting section 20 . The irregular ball distributing part 20 is provided with a gap part 21 for distributing small balls having a diameter smaller than a regulation and a magnetic force drop part 22 for dropping balls attracted by a magnet to the outside of the path to form a distributing passage.

Referring also to FIG. 5, the gap portion 21 has protruding pieces 23 on both sides of the passage that protrude inward from the side wall 20a of the internal passage of the irregular ball sorting portion 20 and extend along the passage. Here, if the game ball B has a specified diameter, it will pass over the gap 21 by rolling with its side part hooked on the protruding piece 23, but if it has a diameter smaller than the specified diameter, If it is a small ball, it falls through the gap between the projecting pieces 23 on both sides.

Further referring to FIG. 6, a small ball passage 21a is provided below the gap 21 to guide the small balls dropped in the gap 21 downward. On the other hand, inside a distribution passage cover 26 forming the ceiling of the distribution passage, a plate-shaped magnet 27 is provided so as to extend along the ceiling of the passage. Here, the game ball B that has passed over the gap portion 21 is directed to the distribution main passage 25 in the center. It falls into the ball passage 22a and does not fall into the sorting main passage 25. - 特許庁The iron ball passage 22a merges with the small ball passage 21a and is connected to the illegal ball outlet 29 (see FIG. 2). That is, among game balls passing through the main inclined passage, illegal balls such as small balls and iron balls are guided to the illegal ball discharge port 29. - 特許庁On the other hand, the game ball B, which has a prescribed diameter and is not attracted by the magnet, passes through the distribution main passage 25 and flows downward.

As shown in FIG. 7 , the distribution main passage 25 is connected to the lower ball gutter 30 . The lower ball gutter 30 forms an inclined passage so that the game ball B flows down, and the traveling direction thereof is bent as follows. That is, from the entrance 31a of the lower ball gutter 30, proceed toward the left on the front side horizontal course 31, proceed toward the back on the left side vertical course 32, and proceed on the central horizontal course 33 to the right. In addition, the central lateral course 33 has a crank portion 33a at its center which advances toward the near side. From the center lateral course 33, the right side longitudinal course 34 is turned toward the back again, and the far side lateral course 35 is turned to the left. In addition, the far side lateral path 35 has a large inclined portion 35a at its center. The far side lateral course 35 has a bent portion 35b that bends toward the front and then bends toward the left again, and the tip of the bent portion 35b forms an exit 36 of the main inclined passage. That is, the main inclined passage is an inclined passage that continues from the receiving opening 11 of the ball receiving portion 10 to the outlet 36, and rolls the game balls individually to the ball feeding portion 40 arranged in the vicinity of the lower portion of the ball raising portion 50. In addition, the lower ball gutter 30 is provided with sensors 30a and 30b for detecting the passage of game balls on the front side lateral path 31 and the back side lateral path 35, respectively, and the number of passing game balls can be counted at two points. can be done. In addition, the exit 36 is provided with a sensor 37 for detecting passage of the game ball B, is connected to the ball feeding part 40, and forms a waiting part in which only one game ball can be stored just before it.

Depending on the number of game balls to be circulated in the ball shooting/recovery unit 1, the lower ball gutter 30 may be, for example, a reservoir for continuously storing the game balls B in a row up to the lateral path 31 on the front side. may In such a case, by forming the lower ball gutter 30 as a meandering path that is bent as described above, a long inclined path is formed while having an inclination that does not hinder the flow of the game balls, and it is compact and can be stored. The number of possible game balls B can be increased. Thus, it is possible to prevent interruption of shooting game balls even in an enclosed type game machine having many accessories for retaining or storing game balls on the game board surface.

Further, the lower ball gutter 30 is bent as described above so as not to apply a large pressure to the stored game ball at the tip. For example, in the crank portion 33a, part of the pressure of the stored game balls is borne by the wall surface, the pressure between the game balls is reduced, and ball biting is suppressed. In addition, the pressure of the game ball from the inclined portion 35a reliably feeds the game ball into the ball feeding portion 40, and the bending portion 35b relieves the pressure of the game ball from the outlet 36 toward the ball feeding portion 40 to prevent ball clogging. I try to suppress it. In addition, a horizontal bent portion may be provided in the middle of the above-described storage portion, such as making the inclination of the bent portion 35b substantially horizontal, to further relieve the pressure of the game ball.

As shown in FIG. 8, the ball feeding section 40 connects to the outlet 36 (see FIG. 7) and the outlet 112a of the main inclined passage and return ball inclined passage 112, respectively, and closes the outlet 36 and the outlet 112a at their peripheries. It has a rotating disk 41 that horizontally rotates while rotating. A rotating disk 41 has a notch 42 in a part of its peripheral edge, and only one game ball B can be accommodated in the notch 42.例文帳に追加Thereby, one game ball B can be accommodated when the notch 42 not accommodating the game ball B is positioned to face the exit 36 or the exit 112a. In addition, the peripheral edge portion of the rotating disc 41 also faces the introduction end portion 51a of the introduction passage 51 that rolls and guides the game ball B to the rising ball portion 50 . Thereby, the game ball B can be discharged to the introduction end portion 51a when the notch 42 containing the game ball B is made to face the introduction end portion 51a.

In other words, the rotating disk 41 can accommodate the game balls from the exit 36 or the exit 112a in the notch 42 and discharge the game balls from the notch 42 to the lead-in end portion 51a. Here, as for the direction of rotation of the rotating disk 41, the notch 42 that has been emptied by the discharge of the game ball to the lead-in end 51a is first passed in front of the exit 112a of the inclined return ball passage 112, and then the main inclined path. Make it pass in front of the exit 36 of the passageway. That is, in the figure, the introduction end portion 51a, the outlet 112a, and the outlet 36 are arranged in this order counterclockwise, and the rotating disk 41 is rotated counterclockwise. With such an arrangement, the ball feeder 40 can preferentially guide the return ball from the return ball inclined passage 112 to the introduction passage 51 rather than the game ball from the main inclined passage.

Although two notches 42 are provided in this embodiment, the number of notches 42 may be singular or plural. Since it is preferable to synchronize with the rising ball portion 50 which will be described later, when a plurality of cutouts 42 are provided, they are preferably arranged around the rotating disk 41 at regular intervals.

Referring also to FIG. 9, the ball rising section 50 to which the game ball is guided from the ball feeding section 40 includes a screw 52 having a spiral blade that rotates around a rotation axis L extending in a substantially vertical direction. A casing 53 is provided around the screw 52 so as to cover the sides thereof. The casing 53 is provided with a discharge end 54 connected downward to the introduction passage 51 to serve as its discharge port, a groove 55 extending in a substantially vertical direction and bulging forward, and an outlet 56 opening upward toward the front. The groove 55 can hold only one game ball in the horizontal direction between itself and the screw 52 , and can move vertically while holding the game ball received from the discharge end 54 by the rotation of the screw 52 . In addition, the bottom of the groove 55 is provided with a window 55a extending vertically so as to expose the outer periphery of the game ball to the front side.

The screw 52 is connected to a gear group 62 at the upper end of its shaft and is driven by a motor 61 . The lower end of the shaft of the screw 52 is connected to another gear group (not shown) to transmit the driving force to the rotating disc 41 and to synchronize its rotation with the rotating disc 41 . As a result, the ball-rising part 50 lifts the game ball received from the discharge end 54 of the introduction passage 51 along the groove 55 while exposing it to the front side through the window 55 a and discharges it from the exit 56 . In addition, the timing of receiving the game ball from the ball feeder 40 can be synchronized with the game ball to be lifted. For example, the rotation of the rotating disk 41 can be controlled in synchronism with the screw 52 so that only one game ball is placed in the lead-in passage 51, thereby preventing ball biting in the rising ball section 50. obtain. The rotation of the rotating disk 41 and the screw 52 is preferably controlled according to the number of game balls stored on the launch rail 104 of the launch unit 100 .

As shown in FIG. 10, a polishing sheet 71 is arranged on the front side of the ascending ball portion 50 so as to cover most of the window 55a. The polishing sheet 71 is a belt-like body exposed from the polishing unit 70 toward the back, and the exposed portion is substantially flat. In other words, it is exposed to the path of the game ball that is vertically moved by the ball-rising part 50 and comes into contact with the game ball. Since the polishing sheet 71 is brought into contact with the game balls moved by the ball rising section 50 in this way, the ball shooting/recovery unit 1 including the polishing unit 70 can be compactly configured while suppressing ball clogging.

Further, the polishing sheet 71 can be moved in the longitudinal direction by the rotation of the roller 72 in the polishing unit 70 to move the exposed portion. In this embodiment, the abrasive sheet 71 is fed parallel to the path of the game ball, but it may be fed in a direction perpendicular to the path of the game ball. It is preferable that the polishing unit 70 is of a cassette type and detachable. For example, in this embodiment, the cassette-type polishing unit 70 is inserted from the front side and fixed with a lock lever 73 (see FIG. 1). The polishing unit 70 may also include a detection section that detects dirt on the polishing sheet 71 . For example, the detection unit can project light onto the polishing sheet 71 and determine the presence or absence of contamination based on reflected light or transmitted light. Further, when the polishing unit 70 detects dirt on the polishing sheet 71, the polishing unit 70 may receive the detection signal and rotate the roller 72 to expose a new surface of the polishing sheet 71 to the path of the game ball. . Further, it is preferable that the polishing sheet 71 be detachable from the polishing unit 70 to facilitate replacement of the polishing sheet 71 .

As shown in FIG. 11 , the game ball lifted by the screw 52 of the ball rising section 50 is introduced into the upper ball gutter 90 from the upper ball gutter entrance 91 . That is, the upper ball gutter entrance 91 is opened toward the back and is connected to the exit 56 (see FIG. 9) of the ascending ball section 50 . The upper ball gutter 90 includes a straight part 92 extending rightward from the upper ball gutter entrance 91, a ball removal shutter 93 bending forward at the tip thereof, a bending part 94 bending leftward, and a meandering part. 95 and continues to the upper ball gutter outlet 96. The upper ball gutter outlet 96 communicates with the ball loading port 101 via a ball feeder (not shown). In other words, the upper layer ball gutter 90 and the shot ball feeder are combined to form the shot part passage. In addition, the upper ball gutter 90 is preferably provided with sensors for detecting the passage of game balls at two locations to count and monitor the passing game balls. As the shot ball feeding device, a known device capable of supplying game balls to the shot ball loading port 101 one by one can be used. For example, it is a device that drives a shutter member that switches between stopping and passing of a game ball by means of a solenoid. Further, by moving the pin 93a toward the back, the ball removal shutter 93 rotates about the rotation shaft 93b to be in the open position, and the game ball flowing down the upper ball gutter 90 is discharged into the ball removal passage 120 below. can be dropped.

As shown in FIG. 12, the ball extracting mechanism 130 for driving the ball extracting shutter 93 has a main slide body 131 to which the ball extracting button 121 is fixed and a sub slide body 132 to which the ejection exit blocking piece 122 is fixed. It is held by the mechanism base body 133 so as to be slidable forward and backward (front-to-back). The main slide body 131 has a cavity 131a penetrating vertically through its center, and a spring support part 133a extending from a ball removing mechanism base body 133 is inserted into the cavity 131a from below. A compression spring 134 is provided between the front side wall of the cavity 131a and the spring support portion 133a, and biases the main slide body 131 toward the front side with respect to the ball extracting mechanism base body 133. As shown in FIG.

Referring also to FIG. 13, a link arm 135 for interlocking the main slide body 131 and the sub-slide body 132 is provided below the main slide body 131 and the sub-slide body 132 . The link arm 135 is rotatably supported by a rotation shaft (not shown) extending upward from the ball extracting mechanism base body 133 at an arm rotation bearing 135 a at substantially the center. One end of the link arm 135 is provided with a first elongated hole 135b whose longitudinal direction is the direction facing the arm rotation bearing 135a. is inserted into The other end of the link arm 135 is similarly provided with a second elongated hole 135c whose longitudinal direction is the direction facing the arm rotation bearing 135a. is inserted into A concave portion 131d formed by an elongated hole whose longitudinal direction is the horizontal direction is provided on the lower surface of the right convex portion 131c of the main slide body 131, into which the pin 93a of the above-mentioned ball removal shutter 93 is slidably inserted.

In addition, the main slide body 131 has a central protrusion 131b on the inner side surface of the center, and when it is slid to the inner side, the central protrusion 131b is engaged with a push latch 136 provided on the ball removing mechanism base body 133 and pushed. The rearward slid position can be maintained even against the bias of the spring 134 . In addition, the main slide body 131 is provided with a projecting piece 131f at a position on the far side of the sub slide body 132, and when it is slid to the back, it is slid to the back by a photo sensor 137 provided on the ball removing mechanism base body 133. detected to be in the specified position. Based on such detection by the photo sensor 137, the ball shooting/retrieving unit 1 drives the shooting section 100 to shoot a game ball guided from the shooting section passage (the upper ball gutter 90 and the shooting ball feeding device). .

In other words, when the ball extracting button 121 is pushed inward, the main slide body 131 slides inward, and the first elongated hole 135b into which the pin body 131e is inserted and the pin 93a inserted in the recess 131d are displaced. move it inside. As a result, the pin 93a moved to the back opens the ball release shutter 93 and drops the game ball flowing down the upper ball gutter 90 into the ball release passage 120 below. At the same time, the first elongated hole 135b that has been moved to the back rotates the link arm 135 to move the second elongated hole 135c forward. As a result, the sub-slide body 132 is moved forward together with the pin body 132a inserted into the second elongated hole 135c. As the sub-slide body 132 moves forward, the ejection outlet blocking piece 122 also moves forward to block the ejection outlet 109 . At the same time, the projecting piece 131f provided on the main slide body 131 is detected by the photosensor 137 and causes the shooting section 100 to shoot a game ball. In other words, the shooting section 100 is operated in conjunction with the depression of the ball ejecting button 121 . In addition, the ball feeding section 40 and the ball raising section 50 are also operated in accordance with the operation of the shooting section 100 .

As a result, the game ball flowing down the upper ball gutter 90 is dropped from the ball removal shutter 93 to the ball removal passage 120 below. At the same time, the game ball downstream of the ball release shutter 93 is shot, and the game ball B hit by the ejection outlet blocking piece 122 blocking the ejection outlet 109 is led to the foul ball recovery port 111 (see FIG. 2). From the foul ball recovery port 111, the game ball B passes through the return ball inclined passage 112, is guided from the exit 112a to the upper layer ball gutter 90 via the ball feeding portion 40 and the ball rising portion 50, and passes through the ball removal shutter 93 to the ball removal passage 120. (see FIG. 8). In this way, all game balls circulating in the ball shooting/recovery unit 1 can be guided to the ball removal passage 120 and discharged by opening the ball removal passage door 129.例文帳に追加When the ball eject button 121 is pushed backward again, the lock of the push latch 136 is released, and the main slide body 131 and the sub-slide body 132 are returned to their original positions by the biasing force of the push spring 134. 122 also returns to its original position to open the ejection outlet 109 .

In this way, all ball removal can be completed simply by pressing the ball removal button 121 to the back when exchanging game balls.
