Description

[Detailed explanation of the invention] <Industrial application field> The invention consists of an overflow ball gutter that receives balls spilled from the prize ball outlet when the opening/closing panel is opened, and a ball gutter that collects fall balls flowing down on the guide rail. A pachinko machine that is provided with a ball gutter that allows the balls in the upper tray to flow down to the lower tray, and a height difference between the outlet of the overflowing ball gutter, the outlet of the fur ball gutter, and the outlet of the ejected ball gutter. It is related to.

<Conventional technology> An overflow ball gutter that collects balls spilled from the prize ball outlet when the opening/closing panel is opened, a fall ball gutter that collects the balls flowing down on the guide rail, and a fall ball gutter that collects the balls in the upper tray. A pachinko machine equipped with a ball gutter that flows down into a tray is known from Japanese Utility Model Application Publication No. 102087/1987 by the present applicant. In such conventional pachinko machines, the outlet of the overflowing ball gutter and the outlet of the ejecting ball gutter are at the same height and intersect with each other at right angles to merge into a merging gutter, and the downstream end of the merging gutter is placed downward. It was connected to the dish.

<Problem that the invention aims to solve> For this reason, for example, if multiple balls overflow and flow down the ball gutter, the balls will pass through the merging gutter and flow back to the outlet of the adjacent ejection gutter. On the other hand, if the balls pulled out of the upper tray flow down the ball gutter, the balls may overflow and flow back to the outlet of the ball gutter, making it impossible to remove the balls smoothly.

In addition, if the opening/closing panel is opened when a large number of balls have accumulated in the upper tray, such as when a malfunction occurs in the ball supply mechanism during operation of the game parlor, the balls overflowing from the prize ball outlet will overflow. Balls do not enter smoothly into the ball sockets of the gutter and may fall onto the floor and be lost, causing discomfort and disadvantage to players.

<Means for solving the problem> This proposal was proposed in view of the above. A frame board is provided on the back side of the front frame, and the game board mounting portion of the frame board is surrounded by guide rails on the surface. A prize ball outlet for discharging prize balls to the upper tray is arranged above one side of the frame board, and a prize ball outlet for discharging prize balls to the upper tray is arranged so that the lower end of the game board forming the game part is located. In a pachinko machine with a firing rail attached to the front side, the front side of the frame board is provided with a vertical ball gutter in which a ball socket is opened between the sloped upper end of the firing rail and the sloped lower end of the guide rail. At the same time, a ball socket wider than the width of the prize ball outlet opens upward, and an overflow ball gutter slopes downward toward the fur ball gutter side, and the prize balls flowing out from the above-mentioned upper tray flow in. Drawn ball gutter having an inlet and sloping downward toward the Fuar ball gutter side are provided oppositely on the left and right sides of the Fuar ball gutter, and the sloped lower ends of both gutters are connected to the left and right sides of the Fuar ball gutter to prevent overflow. A difference in height is provided between the outlet of the overflowing ball gutter, the outlet of the Fouar ball gutter, and the outlet of the ejecting ball gutter at the part where the ball gutter, the FAR ball gutter, and the draining ball gutter merge.

<Function> In this project, at the part where the overflow ball gutter, the FAR ball gutter, and the pull-out ball gutter meet, a height difference is created between the outlet of the overflow ball gutter, the outlet of the FAR ball gutter, and the outlet of the pull-out ball gutter. Even when the balls flowing down are concentrated at the outlet of each gutter, they smoothly flow down and flow into the lower tray without causing stone wall-like ball clogging. In addition, even if a ball that has flown down the drain ball gutter and a ball that has flown down the overflow ball gutter collide at the outlet of each gutter, the ball will not stop because the flowing pressure of each ball is balanced by facing each other with a step. The phenomenon disappears. Therefore, the balls can be smoothly rectified at the merging portion, and the ball discharge process can be carried out efficiently.

When fixed in this manner, a game board storage space for storing the game board 11 is formed on the back side of the front frame 3.

The game board 11 to be stored in the game board storage space in the frame 10 is made by pasting sheet-like cells with an appropriate decorative pattern on the surface of a board material such as plywood cut to a predetermined size. A strip plate-shaped guide rail 66 is fixed to the surface of the cell in a substantially circular shape to form a game section 67, and a countless number of obstacle nails are planted in the game section 67, and a general prize opening, special prize opening, A winning device 68 such as a conversion winning device, a conversion display device 69, etc. are provided, a side case 70, a lamp display 71, etc. are provided on the outside of the gaming section 67, and the back side is provided with winning devices 68, etc. that are discharged from each winning device 68. The system is equipped with a prize-winning ball collection gutter, etc. to collect the winning balls.

To store the game board 11 in the game board storage space of the frame 10, open the glass storage frame 5 and opening/closing panel 7, and insert the game board 11 from the front of the front frame 3 through the window 2 into the frame 10. The lower edge of the game board 11 is placed on the game board mounting portion 23 of the frame board 21, and the back surface of the game board 11 is brought into contact with the back surface 15 of the frame 10. In this way, the game board 11 is brought into contact with the back surface 15 of the frame 10. When the game board 11 is stored in the frame 10 in this manner, the side edge of the back side of the game board 11 comes into contact with the inclined positioning piece 20' of the game board locking member 20 during storage, and is guided to a predetermined left and right position. determined in position. Further, a game board guide portion 19 protruding from the back surface 15 of the frame 10 guides the game board 11 to a predetermined height. Therefore, the game board 11 is installed at a predetermined position within the frame 10.

To stop the game board 11 housed in the frame 10, rotate the operating levers of each game board locking member 20 arranged on the upper and lower sides of the left and right side walls 12, 12 of the frame 10, and release the locking piece of the operating lever. The game board 11 is strongly pressed against the back surface 15 of the frame 10 by being locked to the outer surface of the reinforcing material with a shielding wall attached to the side edge of the game board 11. Therefore, the four game board locking members 20...
The game board 11 can be firmly locked by each locking piece.

Note that a hook 72 is provided at the lower end of the surface of the game board 11, and a toggle-type stop consisting of a locking ring 73 on the front surface 26 of the frame board 21 below the hook 72 and a lever 74 that pulls the locking ring 73 downward. By providing a locking ring 73 to the hook 72 on the game board side and pulling it downward with the lever 74, the game board 11 can be locked even more firmly.

When the game board 11 is housed in the frame 10 as described above and is locked by the game board locking member 20..., the prize ball discharge gutter fits into the prize ball gutter fitting part 25 to guide the prize ball. The outlet 24 opens forward, and the sloping lower end of the guide rail 66 faces the upper left end of the Far ball socket 59, and as shown in FIG. , and the outlet 38 of the discharge ball gutter 32 are connected to the inlet of the merging gutter 75 and communicate with the lower plate 8 via the merging gutter 75. Then, when the glass storage frame 5 is closed by manually pressing each free end side of the opening/closing panel 7 toward the front frame side, and the opening/closing panel is locked by a locking device (not shown) provided on the back side of the front frame 3, the opening/closing panel 7 is closed. A short connection gutter 76 protruding from the back side of the opening/closing panel 7 connects to the prize ball outlet 24 and communicates the prize ball outlet 24 with the upper tray 6, and also serves as a ball outlet of the ball extraction mechanism provided on the back side of the opening/closing panel 7. 77
communicates with the inlet 37 of the drain ball gutter 32, and
A ball supply port 78 of a ball supply mechanism arranged on the back side of the opening/closing panel 7 faces above the firing rail 28.

Therefore, when a ball is put into the upper tray 6 and the firing operation unit 9 is operated, the ball supply mechanism is activated and the balls introduced from the upper tray 6 are supplied one by one onto the firing rail 28 from the ball supply port 78. At the same time, the ball supplied to the firing position 51 at the inclined lower end of the firing rail 28 can be fired by rotating the firing rod 79 of the firing device. The ball fired by the firing rod 79 enters the game section 67 via the guide rail 66, hits an obstacle nail and flows down while changing the direction of flow, and if it enters any of the prize winning tools 68 on the way down. If the ball is a safe ball and does not land in any of the prize winning tools 68, it will be sent to the exit port 80 at the bottom of the gaming section 67.
The ball enters, becomes an out ball, and is discharged to the back side of the game board 11. When the ball hit is a safe ball, a prize ball discharge device (not shown) provided on the back side of the game board 11 is activated and a predetermined number of balls are flown down. These balls flow down in the prize ball discharge gutter and from the prize ball outlet 24 to the connection gutter 76.
The ball is discharged to the upper tray 6 as a prize ball.

On the other hand, a batted ball that does not enter the gaming section 67 due to insufficient flight distance, or a batted ball that once enters the gaming section 67 but hits an obstacle such as a nail and returns to the guide rail 66 becomes a foul ball, and the ball hits the guide rail 66. 66 toward the firing position 51, and the Fuar ball socket 59
The water flows into the fur ball gutter 29 from there. The Far balls that have flowed into the Far ball gutter 29 flow down through the merging gutter 75 from the outlet 61 at the lower end of the Far ball gutter 29, and are collected in the lower tray 8.

If a problem such as a hit ball getting caught in the ball feeding device occurs during the game described above, the glass storage frame 5 is opened and the opening/closing panel 7 is then opened to deal with the problem. At this time, if a large amount of balls are accumulated in the upper tray 6, when the glass storage frame 5 is opened and the connection gutter 76 is detached from the prize ball outlet 24, the balls will be removed from the connection gutter 76 and the prize ball outlet 24. spills. The spilled balls are received by a ball socket 54 that is open below the prize ball outlet 24 and flow into the overflow ball gutter 30. The balls that have flowed into the overflow ball gutter 30 flow down the gutter, then flow into the merging gutter 75 from the outlet 56 and are discharged into the lower tray 8. In this embodiment, the ball socket 54 is sufficiently wider than the prize ball outlet 24, and the flow path is widened by the overflow ball gutter flow path expansion chamber 27, so that a large number of balls can be played simultaneously. Even if the balls spill, they can all be caught by the wide ball socket 54 and collected from the overflowing ball gutter 30 to the lower tray 8 via the merging gutter 75. Even if a large number of balls flow down into the overflow ball gutter 30, the outlet 56 of the overflow ball gutter 30, the outlet 61 of the fur ball gutter 29, and the outlet 38 of the pull ball gutter 32
Since there is a difference in height between them, the balls flowing out from the outlet 56 of the overflow ball gutter 30 reach the Fual ball gutter 2.
There is no backflow to the outlet of 9 or the outlet of the discharge ball gutter 32, and there is no risk of the balls clogging at the junction with the merging gutter 75.

If you want to stop the game and exchange the prize ball for a prize, or move to another pachinko machine and play, the upper tray 6
The ball is caused to flow into the upper tray 6 and into the lower tray 8 by operating the ball extraction operation part 81 provided in the upper tray 6 by the action of the ball extraction mechanism. When the ball extraction operation section 81 is operated, the ball in the upper tray 6 comes out from the ball outlet 77 on the back side of the opening/closing panel 7 and enters the ball extraction channel 32 on the frame board 21 side. The balls that have entered the ball extraction gutter 32 are discharged into the lower tray 8 through the merging gutter 75. In the ball gutter 32 of this embodiment, the width of the flow path including the flow path expansion chamber 31 for the gutter is formed to be more than twice the diameter of the ball, so that the ball in the upper tray 6 is transferred to the lower tray 8. It can be flowed down quickly. In addition, since the outlet 38 of the drain ball gutter 32 is located lower than the outlet 56 of the overflow ball gutter 30 and the outlet 61 of the full ball gutter 29, the outlet 38 of the drain ball gutter 32
Even if the balls flow down inside, there is no possibility that these balls will overflow and flow back to the outlet of the ball gutter 30 or the outlet of the Fouar ball gutter 29, and there is no fear that the balls will become clogged at the merging part with the merging gutter 75.

In the above embodiment, the outlet 56 of the overflow ball gutter 30 merges with the merge gutter 75 at the highest position, and the outlet 38 of the drain ball gutter 32 merges with the merge gutter 75 at the lowest position. As long as a height difference is provided at the outlet of each of the gutter 30, the fur ball gutter 29, and the discharge ball gutter 32, and the gutter 30, the fur ball gutter 29, and the discharge gutter 32 are merged into the merging gutter 75, they may be merged in any height order.

<Effects of the invention> As explained above, according to the invention, the overflow ball gutter and the pull-out ball gutter are provided oppositely on the left and right sides of the Fuar ball gutter, and the inclined lower ends of the two gutter are placed on the left and right sides of the Fuar ball gutter. Since there is a difference in height between the outlet of the overflowing ball gutter, the outlet of the Fual ball gutter, and the outlet of the ejected ball gutter, the balls that spill from the prize ball outlet and flow down forcefully inside the overflowing ball gutter will reach the ejected ball gutter. This prevents inconveniences such as balls flowing back into the outlet side of the ball gutter, or balls flowing down the ball gutter due to the ball removing operation of the upper plate overflowing and flowing back to the outlet side of the ball gutter.
In particular, the outlet of the overflowing ball gutter and the outlet of the draining ball gutter are formed oppositely on the left and right sides of the Fouar ball gutter, with a difference in height, so that the balls flowing down each gutter collide with each other at the outlet of each gutter. Also, the ball's downward pressure is not balanced, and the ball stops phenomenon can be prevented. Therefore, the balls can be smoothly rectified at the merging portion, and the ball discharge process can be carried out efficiently.

In addition, since the ball socket of the overflow ball gutter is made wider than the prize ball outlet, the opening/closing panel can be easily opened and closed when a large number of balls have accumulated in the upper tray, such as when a malfunction occurs during operation of the game parlor. Even if the ball overflows from the connecting gutter or prize ball outlet when the ball is opened, the ball will be automatically caught in the ball socket without spilling onto the floor, and collected from the overflowing ball gutter to the lower tray via the convergence gutter. be able to. Therefore,
Balls are not lost due to scattering on the floor, and players are not made to feel uncomfortable or disadvantaged.
