Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball removal structure for a pachinko machine in which a ball removal opening is provided on the bottom surface of a ball tray that collects pachinko balls paid out from a ball discharge outlet and flows down to the ball launcher side.
[0002]
[Prior art]
A conventional general pachinko machine collects pachinko balls delivered from a ball outlet provided on the front side of the pachinko machine in a ball tray, and places the pachinko balls in a downstream guide channel by a downward slope on the bottom of the ball plate. It is configured to flow down and guide it to the ball launcher. In this configuration, at the end of the game, the player can release almost all the pachinko balls stored in the ball tray by opening the ball outlet provided in the downstream portion of the guide channel. When the amount of pachinko balls stored in the ball dish is large, there is a disadvantage that it takes time to complete the ball removal.
[0003]
In order to solve this drawback, as shown in Japanese Patent Application Laid-Open No. 11-9794, a ball outlet is also provided at the center of the bottom of the ball tray, so that two balls on the ball tray bottom and the guide channel are provided. Proposals have been made so that pachinko balls can be discharged from the opening. If only the ball outlet at the center of the bottom of the ball pan is opened, only the pachinko ball upstream from the ball outlet at the bottom of the ball pan is removed. The pachinko ball to be supplied to the ball launcher can be left. Therefore, when pachinko balls are continuously being paid out in large hits, etc., if only the ball outlet at the bottom of the ball tray is opened while playing a game, the pachinko balls upstream of the ball outlet are removed. There is an advantage that the game can be continued while preventing the ball tray from becoming full.
[0004]
[Problems to be solved by the invention]
However, in the above conventional configuration, since the ball outlet is provided at the center of the bottom surface of the ball tray, when the ball outlet at the center of the bottom surface of the ball tray is opened, a pachinko ball that is newly dispensed to the upstream portion of the ball tray Most of the water is discharged from the ball outlet at the center of the bottom of the ball tray. For this reason, even when pachinko balls are continuously paid out in large hits etc., the number of pachinko balls that roll down the side of the ball outlet and flow down to the downstream part of the ball dish is the number of pachinko balls. There is a possibility that the number of shots may be smaller than the number of shots. As a result, there is a possibility that the shot balls may be lost in a relatively short time when the ball is removed and the game cannot be continued. To avoid this, every time the pachinko ball storage amount in the ball tray decreases when the ball is removed, the ball outlet on the bottom of the ball plate can be closed to increase the pachinko ball storage amount. The player has to open and close the ball opening on the bottom of the ball tray many times, which is very troublesome.
[0005]
In addition, it is possible to increase the number of pachinko balls that flow down the side of the ball outlet by reducing the ball outlet on the bottom of the ball tray, but this increases the time for ball removal at the end of the game. End up.
[0006]
The present invention has been made in view of such circumstances. Therefore, the object of the present invention is to hold the ball outlet on the bottom of the ball tray in an open state so that the pachinko balls in the ball tray are removed from the ball bottom. You can continue playing the game by supplying enough pachinko balls to the downstream part of the ball dish while removing the ball from the mouth moderately, eliminating the trouble of the ball removal operation during the game and removing the ball at the end of the game It is to provide a ball punching structure for a pachinko machine that does not slow down.
[0007]
[Means for Solving the Problems]
By the way, when the amount of pachinko balls stored in the bowl is large, the pachinko balls flow almost uniformly over the entire bottom of the bowl, so the speed of ball removal from the bowl outlet on the bottom of the bowl is the position of the ball outlet. The opening area of the ball outlet is more related than the opening area of the ball outlet. The larger the opening area of the ball outlet, the shorter the ball removal time. On the other hand, when the amount of pachinko balls stored in the ball tray decreases, the pachinko balls that flow into the ball tray from the ball payout exit roll forward from the ball payout exit. If it does not collide with other pachinko balls, it rolls toward the front inner wall surface of the ball tray, and gradually rolls down the rolling plate due to the curved surface of the front inner wall surface of the ball tray or the downward slope of the bottom surface of the ball plate. Change direction and flow down to the downstream of the bowl. For this reason, when the amount of pachinko balls stored in the ball tray is reduced, the ratio of pachinko balls flowing into the ball tray from the ball discharge outlet tends to increase along the front inner wall surface of the ball tray.
[0011]
Paying attention to such characteristics, the invention according to claim 1 guides the flow of pachinko balls flowing down the bottom surface of the ball dish to the outer peripheral side of the ball outlet, at least upstream of the peripheral portion of the ball outlet. The ball flow restricting means is provided, and the ball flow restricting means is configured by a convex wall portion surrounding at least the upstream side of the peripheral portion of the ball outlet (in this case, the position of the ball outlet is Not limited). In this configuration, when the amount of pachinko balls stored in the ball pan is reduced, the ball flow restricting means (convex wall) prevents the pachinko ball flowing down the bottom of the ball pan from entering the ball outlet. . Thus, the game can be continued while the pachinko ball in the ball tray is appropriately removed from the ball outlet while the ball outlet on the bottom of the ball tray is kept open. Moreover, since the opening area of the ball outlet can be increased to some extent due to the presence of the ball flow restricting means (convex wall portion), the time for ball removal at the end of the game can be shortened.
In this case, as described in claim 2, it is desirable that the height dimension of the convex wall portion is set to a dimension around 1/2 of the diameter of the pachinko sphere. In this configuration, when the amount of pachinko balls stored in the ball pan is small, the flow of the pachinko balls flowing down the bottom surface of the ball pan is moved to the outer peripheral side of the ball vent at the convex wall even if the ball vent is open. Since it is guided, the pachinko ball can be prevented from flowing into the ball outlet. Therefore, when the game is continued while the ball outlet is kept open, when the amount of pachinko balls stored in the ball pan is reduced, the pachinko ball flowing into the ball pan is securely placed on the ball launcher side. Can be supplied to. Further, if the amount of pachinko balls stored in the ball tray increases, the pachinko balls on the upstream side of the ball outlet in the ball tray are removed from the ball outlet over the convex wall portion.

As shown in FIG. 2, the first ball removal port 28 is provided with a first ball removal member 30 for opening and closing the first ball removal port 28, and a first operation provided on the front surface of the ball tray 20. The first ball removal member 30 is slid laterally (rightward) as shown by a two-dot chain line with a lever (not shown) to open the first ball removal port 28, so that the pachinko ball becomes the first ball. It can be dropped from the outlet 28 to the ball discharge path 31 and discharged outside the machine. In the present embodiment (1), the first ball outlet 28 corresponds to the ball outlet referred to in the claims.
[0016]
Further, the bottom surface 23 of the front dish portion 21 is provided with a step at substantially the center position of the first ball outlet 28, and the bottom surface 23a of the right side portion is formed to be higher than the bottom surface 23b of the left side portion. Thereby, at the time of closing the first ball outlet 28, while preventing the formation of a step that inhibits the flow of the pachinko ball at the boundary between the upper surface of the first ball extraction member 30 and the bottom surface 23b of the left side portion, When the ball outlet 28 is opened, the first ball release member 30 can be stored below the bottom surface 23a of the right portion only by sliding the first ball release member 30 linearly in the lateral direction (right direction). ing.
[0017]
Further, as shown in FIG. 1, a portion of the front inner wall surface 32 of the front plate portion 21 facing the communication port 26 has an inclination angle of at least a portion facing the central portion of the communication port 26 with respect to the front panel 19. It is formed to be 40 to 60 °.

Is hooked on a locked portion (not shown) of the front panel 19 to lock the crime prevention cover 33 in a closed state (a state in which the rear plate portion 22 is covered). The crime prevention cover 33 is integrally formed with a single ball flow guide plate 35 that disperses pachinko balls that flow into the rear dish portion 22 from the ball outlet 27 into the corners of the rear tray portion 22. The storage space for the pachinko balls in the rear dish portion 22 is partially partitioned into two stages vertically by the plate 35. In addition, on the left and right sides and the front edge of the ball flow guide plate 35, a plurality of ball drop openings for dropping pachinko balls on the ball flow guide plate 35 into the storage space on the lower side (below the ball flow guide plate 35). 36 is provided.
[0020]
Further, a fullness detection switch 37 including a fullness detection lever 37 and a microswitch that is turned on / off by the fullness detection lever 37 is provided behind the ball flow guide plate 35. When the full detection lever 37 is pushed by the pressure of the pachinko ball stored in the upper storage space of the rear plate portion 22 and swings backward, the full detection switch 38 is turned on.
[0021]
The pachinko machine is also provided with a winning ball sensor (not shown) for detecting that a pachinko ball has won, and a card unit (not shown) for lending a ball. These winning ball sensors, card units, and full detection The output signal of the switch 38 is input to a control circuit (not shown) of the pachinko machine. The control circuit controls the operation of the ball dispensing device 16 based on a winning signal from the winning ball sensor or a ball lending request signal from the card unit, and pays out a pachinko ball.
[0022]
The pachinko balls paid out from the ball dispensing device 16 flow down the ball dispensing channel 17 and flow into the rear dish portion 22 from the ball discharge port 27, flow down through the rear plate portion 22, and then enter the communication port 26. It flows into the front dish part 21 through. When many pachinko balls are continuously paid out from the ball dispensing device 16, the pachinko balls are first stored in the front plate portion 21, and when the front plate portion 21 is full, the next is in the rear plate portion 22. Accumulated. In the rear plate portion 22, first, pachinko balls are stored in the lower storage space, and when the lower storage space is full, the pachinko balls are stored in the upper storage space.
[0023]
When the amount of pachinko balls stored in the ball tray 20 is large (at least when the pachinko balls are accumulated up to the upstream side of the first ball outlet 28), if the first ball outlet 28 is opened while playing a game, The pachinko balls accumulated on the upstream side of the first ball extraction port 28 can be extracted from the first ball extraction port 8 in a short time, and the ball tray 20 can be prevented from becoming full. In this case, since the pachinko ball to be supplied to the ball launching device can be left downstream of the first ball outlet 28, the game can be continued.
[0024]
On the other hand, when the amount of pachinko balls stored in the ball tray 20 is reduced, the pachinko balls flowing into the front dish portion 21 from the communication port 26 roll out forward from the communication port 26, and therefore, the solid line arrows in FIG. As shown, the pachinko balls that have rolled out from the communication port 26 roll down toward the front inner wall surface 32 of the front plate portion 21 as long as they do not collide with other pachinko balls, while descending on the bottom surface 23 of the front plate portion 21. Or the curved surface of the front inner wall surface 32 gradually changes the rolling direction to the downstream direction and flows down to the downstream portion of the front plate portion 21. For this reason, when the amount of pachinko balls stored in the front plate portion 21 is reduced, the ratio of the pachinko balls flowing into the front plate portion 21 from the communication port 26 flows along the front inner wall surface 32 of the front plate portion 21 increases. Tend.
[0025]
Focusing on such characteristics, in the present embodiment (1), the first ball outlet 28 is provided in the vicinity of the rear inner wall surface 29 in the vicinity of the downstream side of the communication port 26. While securing the opening area of 28 and ensuring the ball removal performance when the pachinko ball storage amount is large, when the pachinko ball storage amount is small, the pachinko ball is located between the front inner wall surface 32 and the first ball extraction port 28. It is possible to secure a sufficient flow path. Thus, even if the first ball outlet 28 is opened, the front inner wall surface 32 and the first ball outlet are appropriately removed from the first ball outlet 28 while the pachinko balls flowing into the front dish portion 21 are appropriately removed. The pachinko sphere can be sufficiently supplied to the downstream part of the front dish part 21 by the flow path between the two parts.
[0026]
Therefore, in this embodiment (1), when a large amount of pachinko balls are continuously paid out due to a big hit or the like, if the player keeps the first ball outlet 28 open, The game can be continued by supplying enough pachinko balls to the downstream part of the front plate part 21 while appropriately removing the pachinko balls that are paid out to the ball. There is no need to open and close 28, and the troublesomeness of the ball removal operation can be eliminated. Moreover, since the opening area of the first ball outlet 28 can be increased to some extent, the pachinko balls accumulated on the upstream side of the first ball outlet 28 can be extracted in a short time.
[0027]
By the way, when the pachinko ball vigorously flows into the front dish portion 21 from the communication port 26, the pachinko ball may collide with the front inner wall surface 32 facing the communication port 26 and bounce off. If the ball is rebounded vigorously, there may be less pachinko balls flowing toward the flow path between the front inner wall surface 32 and the first ball outlet 28.
[0028]
In that respect, in the present embodiment (1), a portion of the front inner wall surface 32 facing the communication port 26 has an inclination angle of at least a portion facing the central portion of the communication port 26 with respect to the front panel 19. Since it is formed so as to be 60 °, the pachinko ball rolls straight from the communication port 26 forward (perpendicular to the front panel 19) and collides with the front inner wall surface 32 as shown by a two-dot chain line in FIG. However, the rebound direction is within the range of the direction inclined 10 ° rearward with respect to the downstream direction of the front plate portion 21 (the direction parallel to the front panel 19) and the direction inclined 30 ° forward, and substantially the front inner wall surface 32. The direction along. For this reason, even if the pachinko balls collide with the front inner wall surface 32 when the pachinko ball storage amount decreases, most of the pachinko balls flow between the front inner wall surface 32 and the first ball outlet 28. The path can be flowed down and supplied to the downstream part of the front plate part 21.
[0029]
However, the angle of inclination of the portion of the front inner wall surface 32 facing the communication port 26 is not necessarily 40 to 60 ° with respect to the front panel 19, and the flow characteristics of the pachinko sphere and the first ball outlet 28 and It may be changed as appropriate in consideration of the positional relationship.
[0030]
[Embodiment (2)]
Next, Embodiment (2) of this invention is demonstrated using FIG.4 and FIG.5. In this embodiment (2), as shown in FIGS. 4 and 5, a semicircular convex wall portion 39 is formed on the bottom surface 23 of the front plate portion 21 so as to surround the upstream peripheral portion of the first ball outlet 28. (Ball flow restricting means) are integrally formed. The height dimension of the convex wall portion 39 is set to a dimension (for example, 3 to 7 mm) around 1/2 the diameter of the pachinko sphere. Other configurations are the same as those in the embodiment (1).
[0031]
In the present embodiment (2), since the upstream peripheral portion of the first ball outlet 28 is surrounded by the convex wall portion 39, the first sphere is reduced when the amount of pachinko balls stored in the front plate portion 21 is reduced. Even if the opening 28 is opened, the flow of the pachinko sphere flowing down the bottom surface 23 of the front plate portion 21 is guided to the outer peripheral side of the first sphere opening 28 by the convex wall portion 39. It is possible to prevent entry into the ball outlet 28. Accordingly, when the game is continued while the first ball outlet 28 is kept open, when the amount of pachinko balls stored in the front plate portion 21 is reduced, the pachinko balls flowing into the front plate portion 21 are surely secured. Can be supplied to the downstream part of the front plate part 21 (on the side of the ball launcher). In addition, if the amount of pachinko balls stored in the front plate portion 21 increases, the pachinko balls on the upstream side of the first ball discharge port 28 in the front plate portion 21 exceed the convex wall portion 39 and the first ball discharge port 28. The ball will be removed from.
[0032]
In this embodiment (2), as shown in FIG. 6, the first ball outlet 40 is provided at a position near the front inner wall surface 41 or at the center of the bottom surface 23, and upstream of the first ball outlet 40. You may make it form the semicircular convex wall part 42 (sphere flow control means) so that a peripheral part may be surrounded. Further, the inclination angle of the portion of the front inner wall surface 41 that faces the communication port 26 that faces the central portion of the communication port 26 may be smaller than 40 ° with respect to the front panel 19. Even in this case, it is possible to prevent the pachinko balls from entering the first ball outlet 40 when the storage amount of the pachinko balls in the front plate portion 21 is reduced, so that the big hit etc. When pachinko balls are continuously being dispensed in large quantities, if the first ball outlet 40 is kept in an open state, the pachinko balls can be sufficiently removed from the front plate portion 21 while appropriately removing the pachinko balls. You can continue playing the game by supplying a pachinko ball.
[0033]
In the embodiment (2), the semicircular convex wall portion is formed so as to surround the upstream side periphery of the first bulb outlet, but the shape and position of the convex wall portion may be changed as appropriate, In short, it is only necessary that the flow of pachinko balls flowing down the bottom surface 23 of the front plate portion 21 can be guided to the outer peripheral side of the first ball outlet when the pachinko ball storage amount in the front plate portion 21 decreases. . Moreover, you may make it provide a 1st ball extraction port in the center part of the bottom face 23 of the front plate part 21, or enlarge the magnitude | size of a 1st ball extraction port.
[0034]
Further, in each of the above embodiments (1) and (2), the present invention is applied to the front dish portion 21 provided in front of the front panel 19 in the ball tray 20 composed of the front dish portion 21 and the rear dish portion 22. Although applied, the present invention may be applied to a ball tray provided only in front of the front panel 19.
