It is possible to adjust the flight distance of the hit ball by changing the driving force of.

Although the firing handle 12 is attached to the front side of the opening / closing panel 3 together with the upper plate 10 and the lower plate 11 in the embodiment shown in the drawings, it may be attached to the front frame 5 in a state of being separated from the opening / closing panel 3. Good. When the firing handle 12 is attached to the front frame 5, the hinge mechanism 29 and the lock mechanism 30 of the opening / closing panel 3 are not loaded even if the firing handle 12 is rotated when the front frame 5 is opened and closed.

Next, members provided on the back side of the open / close panel 3 will be described in detail. First, the back surface ball downflow path 26 will be described. The back surface spherical flow-down path 26 is provided with a tubular member which is slightly shorter than the vertical length of the opening / closing panel 3 in the vertical direction.
In this embodiment, the opening portion of the upper end surface is provided with the foul ball recovery port 4
Since it is used as 2, the foul ball recovery port 42 is arranged at a position where it is fitted in the empty space between the inclined lower end of the guide rail 21 and the inclined upper end of the launch rail 18 when the opening / closing panel 3 is closed. . In addition, the lower end surface of this back surface ball flow down path 26 is closed, and the front of this bottom surface is opened as an outlet and overlaps with the second ball passage opening 39 of the opening / closing panel 3 to lower plate 1.
It communicates with the inside of 1.

Therefore, the ball hit by the launching pestle 17 of the ball launching device does not reach the game area 9, or the foul ball bounced back even if it enters the game area 9 moves backward on the guide rail 21a. Fall into the foul ball recovery port 42. Then, the foul ball that has fallen into the foul ball recovery port 42 flows down in the back surface ball downflow path 26 that functions as a foul ball recovery path, and is discharged from the second ball passage opening 39 of the opening / closing panel 3 to the lower plate 11 on the front surface. To be done.

In this embodiment, the opening on the upper end surface of the back surface ball falling path 26 is used as the foul ball collecting port 42, and the back surface ball falling path 26 itself is entirely functioned as a foul ball collecting path. Fal ball recovery port 42
Is provided separately from the back surface ball falling path 26, and the downstream side of the foul ball collecting path is connected (merged) with the back surface ball falling path 26 in the middle thereof.
May be configured to function as part of the foul ball recovery path.

The connecting gutter 27 guides the balls discharged from the ball discharging device provided on the back mechanism board to the upper plate 10 through the outlet 43 of the ball discharging gutter opened in the upright surface 13, and the opening / closing panel 3 A short, substantially rectangular cylinder is provided on the back surface of the.
The tip of the connecting gutter 27 has an upper opening edge so that the opening / closing panel 3 can be smoothly connected / disconnected from the outlet 43 of the ball discharge gutter when the opening / closing panel 3 is opened / closed, and the balls can smoothly flow. Forms an eaves portion 44 having a ball guide surface whose lower surface is inclined downward toward the front, and an auxiliary floor portion 45 is projected at the lower opening edge. When the opening / closing panel 3 is closed, the eaves portion 44 enters the inside of the outlet 43 of the ball discharge trough, and the ball guide surface bounces and guides the falling ball downward, and the auxiliary floor portion 45 is provided at the opening edge of the outlet 43. The gap between the connecting trough 27 and the outlet is eliminated by entering the groove formed below, and the flowing down ball is smoothly flown down toward the upper plate 10. Further, in the present embodiment, the communication gutter 27 is provided with an overflow mechanism for overflowing the flowing down prize balls to the lower plate 11 when the upper plate 10 is filled with balls.

In this overflow mechanism, the floor portion of the connecting gutter 27 is made into a swinging floor 46 which can be swung by the weight of the ball, and between the swinging tip end portion of the swinging floor 46 and the side wall of the connecting gutter 27. An overflow inlet 47 is opened in the above, and an overflow passage 48 is formed from the overflow inlet 47 along the opening / closing panel 3. Then, the overflow channel 48 formed on the back surface side of the opening / closing panel 3 is
The spheres that have overflowed are made to communicate (merge) with the back surface sphere flow-down path 26 provided on the back surface of the opening / closing panel 3, and flow down through the back surface sphere flow-down path 26 that functions as the overflow flow path 48, and then through the second ball passage port 39. It is configured to be discharged to the lower plate 11.

A ball drop prevention wall 49 is formed on the tip end side of the connecting gutter 27 of the overflow inlet 47 to prevent the ball flowing out from the outlet 43 of the ball discharge gutter directly falling into the overflow inlet 47.

The rocking floor 46 is axially attached to one side of the connecting gutter 27, and is always urged upward by a spring 50 to stop in a substantially horizontal posture. Further, a bank portion 51 is formed at the free end side edge of the rocking floor 46 so as to prevent the balls flowing out from the outlet 43 of the ball discharge trough to fall into the overflow inlet 47 as they are. The spring 50 for urging the rocking floor 46 holds the rocking floor 46 horizontally when the balls simply pass over the rocking floor 46, and moves the rocking floor 46 when a certain number of balls are loaded. Select the one that has the power to oscillate.

Therefore, when the ball discharging device flows the ball down in a state that the ball is not full in the upper tray 10, the ball passes from the outlet 43 of the ball discharging gutter to the swing floor 46 of the connecting gutter 27. Then, it is discharged to the upper plate 10. Then, the balls in the upper plate 10 gradually increase and finally become full, and the balls flowing out from the outlet 43 are not discharged into the upper plate 10 but swinging floor 4
6 starts to stay above 6, the balance between the weights of the plurality of balls in the traffic jam and the inability of the spring 50 is lost, and the swing floor 46
Descends on the free end side and inclines downward to the overflow inlet 47 side. Therefore, the ball on the rocking floor 46 and the newly discharged ball fall into the overflow inlet 47. Then, the dropped balls flow down the overflow flow path 48 extending obliquely downward, and then enter the back surface ball flow-down path 26 extending substantially vertically on the back surface of the opening / closing panel 3,
After flowing down the back surface ball downflow path 26 that functions as a part of the overflow flow path 48, the ball flows out through the second ball passage port 39 to the front side of the open / close panel 3 and is discharged to the lower tray 11.

In this manner, when the sphere overflows due to the rocking of the rocking floor 46, the weight of the ball rocking on the rocking floor 46 is lost, so that the rocking floor 46 is biased by the spring 50. It oscillates back to return to a horizontal posture (normal state), and this horizontal state is maintained until the quantity on the oscillating floor 46 falls to some extent. Then, when the prize balls are discharged and a certain number of them are stagnated on the rocking floor 46, the rocking floor 46 rocks due to the weight of the balls, and the stuck balls are overflowed to lower the tray as in the above. Discharge to 11 and store.

When the overflow balls gradually accumulate in the lower plate 11, the lower plate 11 finally becomes full, and then the overflowed balls start to accumulate in the back surface ball flow down passage 26. Therefore, as shown in FIG. 6, a ball pressing plate 55 is provided in the middle of the back surface ball down path 26, and an overflow detector 56 that is turned on / off by the movement of the ball pressing plate 55 is provided so that the ball pressing plate 55 stays. When the overflow detector 56 oscillates due to the ball pressure of the overflow ball and acts on the overflow detector 56, the operation of the hitting ball launching device is stopped based on the signal from the overflow detector 56.

In this way, not only the upper plate 10 but also the lower plate 11 is filled with the balls, and when the overflow balls are accumulated up to the middle of the back surface ball flow down path 26, the ball is shot based on the signal from the overflow detector 56. When the operation of the device is stopped, even if the hit balls shot up to that time are won and the prize balls are discharged several times, further overflow balls are stored in the back surface ball downflow path 26 on the upstream side of the ball pressing plate 55. Is possible.
Therefore, the prize balls discharged from the ball discharging device do not stay in the ball discharging trough. Therefore, even if the open / close panel 3 is opened and the communication gutter 27 is separated from the outlet 43 of the ball discharge gutter, the balls in the ball discharge gutter do not spill.

Next, the sphere supplying device 2 for supplying the spheres in the upper plate 10 one by one to the sphere firing position at the lower end of the inclination of the firing rail 18.
8 will be described. The ball supply device 28 is shown in FIGS.
As shown in FIG. 5, a ball introducing path 61 communicating with the first ball passage opening 35 of the opening / closing panel 3 is formed inside the case 60 attached to the back surface of the opening / closing panel 3, and the inclined lower end of the ball introducing path 61 is provided. In the empty state, the ball supply member 62 is swingably attached to the shaft,
A ball removing passage 63 is formed below the ball introducing passage 61, a ball removing switching valve 64 is provided at the bottom of the ball introducing passage 61, and the ball removing operating portion 36 of the upper tray 10 is connected to the ball removing switching valve 64. I am doing it. Note that FIG. 7 shows the ball supply device 28 in a state where the cover 65 of the case 60 is removed. When the cover 65 is covered, the side surface of the ball introduction path 61 and the like can be closed. The bottom of the flow channel 63 enters the portion indicated by the alternate long and short dash line in FIG. 7 to form the ball-drain flow channel 63. The ball-removing flow path 63 extends to the outside of the case 60 and communicates (merges) with the back-side ball flow-down path 26.

Ball removal switching valve 64 in the ball introduction path 61 described above
Is always closed as shown in FIG. 7 by the biasing of a spring (not shown). Therefore, the balls stored in the upper plate 10 flow down from the first ball passage port 35 into the ball introduction path 61, and the first ball is the U-shaped ball mounting portion 66 of the ball supply member 62.
Stops by contacting the stopper on the top of. When the electromagnet 67 is excited in this state and the iron plate 68 provided on the upper portion of the sphere supply member 62 is attracted, the sphere supply member 62 swings around the shaft 39 in the direction in which the sphere mounting portion 66 rises, Only one ball that has stopped by hitting the stopper due to the rocking falls into the ball mounting portion 66. Then, when the electromagnet 67 is demagnetized, the ball supply member 62 returns and swings due to its own weight, and the ball mounting portion 66.
By moving down, the balls in the ball mounting portion 66 are supplied to the launch rail 18 side from the ball supply port 70 opened in the lid 65.

Therefore, the sphere supplying device 28 includes the electromagnet 6
When 7 is intermittently excited, the balls in the upper plate 10 can be supplied one by one onto the firing rail 18 of the firing unit 14. The ball supplied onto the launch rail 18 rolls due to the tilt of the launch rail 18, stops at the launch position at the lower end of the tilt, and is swung by the rotation of the launching pestle 17.

When the game is finished in a state where the balls remain in the upper plate 10 or when the ball is moved to another pachinko machine 1, the balls in the upper plate 10 must be dropped into the lower plate 11. Therefore, next, the operation of pulling out the balls in the upper plate 10 into the lower plate 11 will be described. When the ball removing operation unit 36 provided on the upper plate 10 is operated, the ball removing switching valve 64 provided at the bottom of the ball introducing passage 61 moves to open the bottom surface, and the ball introducing passage 61 communicates with the ball removing passage 63. To do. Therefore, the sphere stopped in the sphere introduction path 61 and the sphere stored in the upper plate 10 flow down into the sphere removal flow path 63 from the opening,
The sphere that has flowed down into the ball-removing flow path 63, even if it goes out of the case 60, flows down obliquely downward and enters into the back surface sphere flow-down passage 26. Then, after flowing down to the lower end in the back surface ball downflow path 26, it passes through the second ball passage port 39 of the opening / closing panel 3 and is discharged to the lower tray 11 on the surface of the opening / closing panel 3. Therefore,
The back surface spherical flow-down path 26 also functions as the ball removal flow path 63.

A detector for detecting the state where the ball introducing passage 61 communicates with the ball removing passage 63 is provided, for example, a detector which is turned on / off by moving the ball removing operation portion 36 or the ball removing switching valve 64 is provided. , If the detector is connected to the lamp 24,
While the ball is removed, the lamp 24 can be turned on or blinked to make the decorative member 23 shine.

As described above, when the lamp 24 of the decoration member 23 is caused to emit light by interlocking with the ball removing operation, not only the decorative effect can be enhanced, but also the waiting time until all the balls flow down to the lower plate 11 is increased. , You can make you feel short by making you feel the number of balls you have acquired.

In the above-described embodiment, one back surface spherical flow-down passage 26 is provided substantially at the center of the back surface of the opening / closing panel 3, and the back surface spherical flow-down passage 26 is provided with the overflow passage 48, the foul ball collecting passage and the ball removing passage 63. However, it is also possible to provide a plurality of back surface spherical flow-down passages 26 and connect the outlets at the lower ends to the lower tray 11 or to join the outlets at the lower ends.

The present invention is not limited to the pachinko machine 1, but may have any structure as long as it is a ball-and-ball game machine such as a sparrow-ball type game machine, an arrangement ball game machine or the like that shoots a ball to perform a game.

In the ball game machine according to claim 1, the upper plate and the lower plate are provided on the front side of the same opening / closing panel, and the overflow flow path is joined to the back surface ball flow down path provided on the back surface side of the opening / closing panel. It is no longer necessary to form an overflow channel in the back mechanism. Therefore, the structure of the back mechanism board can be simplified, the structure of the molding die of the back mechanism board is simple, and the manufacturing is easy.

Further, by providing the upper plate and the lower plate on the same opening / closing panel, the vertical length of this opening / closing panel can be made larger than before, so that the lower portion of the opening window portion of the front frame is made larger than before. It can be opened. Therefore, the hitting ball launching device can be unitized so that it can be attached and detached from the front side of the gaming machine, and the degree of freedom in design can be expanded.

In the ball-ball game machine according to the second aspect of the invention, since the ball removing flow path from the ball supply device is joined to the back surface ball flow down path, it is necessary to form the ball removing flow path in the back mechanism on the front frame side. Disappears. Therefore, the structure of the back mechanism board can be further simplified, and the structure of the molding die of the back mechanism board is not simpler.
Easy to manufacture.

In the ball game machine according to the third aspect, since the upper plate, the lower plate and the hitting ball launching operation section are provided on the front side of the same opening and closing panel, when the opening and closing panel is opened and closed, the upper plate, the lower plate and the hitting ball are hit. The firing operation part opens and closes together with the opening and closing panel. Therefore, the lower part of the opening window portion of the front frame can be opened further largely, and the degree of freedom in design is further expanded.

In the ball-ball game machine according to the fourth aspect of the invention, the foul ball recovery path is joined with the back surface ball flow down path so that the back surface ball flow down path also functions as the foul ball recovery path. There is no need for a road. Therefore, the structure of the back mechanism board can be further simplified, and the manufacture of the back mechanism board is easier.
