Note that locking means (not shown) are attached to the glass door 4 and the plate plate 5, respectively. A ball ejecting portion 8 is formed at the bent corner of the base end of the ejecting rail 7, and an opening 9 is formed in the member 8 through which a mallet 25 at the tip of a ball hitting rod 24 in a ejecting device, which will be described later, can enter and exit. 1
Reference numeral 1 denotes a lower spherical plate, which is integrally assembled with a plate plate 12 attached to the front lower part of the front frame 2.

As schematically shown in FIG. 2, the upper spherical plate 13 has a case body 14 and a plate body 16 (both made of synthetic resin) assembled and set in the case body 14, both of which are closely attached to the front surface of the plate plate 5. In this state, they are attached with screws or the like and handled as a unit of five plate plates. A lid 15 made of transparent synthetic resin is removably set on the tip of the case body 14 (left end in FIG. 2) with screws or the like. In addition, in the dish main body 16, a housing section (not shown) is provided.
An alignment path 17 and a ball extraction mechanism 18 are formed to sequentially align balls thrown into the side. This mechanism 1
8, when operating the front surface of the spherical dish 13, the opening/closing valve 19 forming a part of the bottom surface of the alignment path 17 is moved to the right in FIG. 2 against the spring 20, thereby opening the alignment path 17. Ball extraction port 21 formed on the bottom
is opened, and the balls in the tray main body 16 can be returned to the lower ball tray 11 side via the ball removal path 22 and the like.

In the firing device, by operating the operating section 23 installed at the lower right portion of the front surface of the front frame 2, a motor (not shown) on the back side of the front frame 2 is driven, and a spring applied to the batting rod 24 is driven. The force is adjusted, and according to the constant rotation of a cam (not shown) on the motor side, the ball striking rod 24 performs an elastic movement that pulls the mallet 25 from the firing site 8, and a forceful movement of the hammer 25 toward the firing site 8. The firing action and firing action can be performed at a constant timing. Reference numeral 26 denotes an operating member installed at the lower front of the ball launcher 6, which controls the rebound of the ball rod 24,

In the above-mentioned pachinko machine, a ball rectifier 27 and a ball feed regulating device 33 are detachably attached to the front and rear surfaces of the tray plate 5, respectively. Ball rectifier 27
Now, screws are attached to the front of the plate plate 5, and the ball plate 1 is attached to the front surface of the plate plate 5.
In the main body 28 incorporated in the case main body 14 of No. 3, there is a rectification path 29 that communicates with the end portion of the alignment path 17 of the dish main body 16 and allows a plurality of balls to pass through in a horizontal line.
A deflection channel 30 is connected to the lower end of the rectifying channel 29 and accommodates one ball while changing the direction obliquely; A standby section 31 is formed in which the pressure of a considerable number of balls from the rectifying path 29 to the dish body 16 is skillfully reduced within the direction change path 30, so that most of the pressure is applied to the balls in the standby path 31. We are trying to adjust the pressure reduction so that it does not occur. Note that this ball rectifier 27 is normally covered with the lid 15, and the outlet of the standby path 31 is aligned with the passage 32 formed in the plate plate 5 (see FIGS. 5 to 7).

On the other hand, in the ball feed regulating device 33, as shown in FIGS.
is equipped with a ball feeding section 33A and a regulating section 33B for the same section 33A. In the base body 34, an inlet 35 is formed at the center of the lower part thereof, and is aligned with the passage 32 of the dish plate 5. A partition wall 36 is formed at the left edge of this inlet 35, and a partition wall 36 is formed at the lateral center. A pair of vertical supporting walls 38, 38 are formed above the lid wall 37.

In the ball feeding section 33A, as shown in FIGS. 3 to 7, first and second control valves 4 are installed in a case 39 that is aligned with the cover wall 37 and screwed to the lower part of the base 34.
6 and 50 are inserted vertically, and the case 39 has a partition wall 40 formed at the center inside thereof and a partition wall 36 on the side of the base body 34 to connect the feed path 41 and the chamber 43.
is divided into left and right sections. Further, the feed path 41 is formed to a size that can accommodate substantially one ball, and is aligned and communicated with the inlet 35, and the outlet 42 is connected to the ejection portion 8 of the ejection rail 7.
It is placed at the top where appropriate. Note that there is a slit 44 between the two partition walls 36 and 40, and a feed path 41.
A slit 4 is provided between the inner end surface of the bottom plate and the base body 34.
5 are formed respectively.

The first control valve 46 moves up and down in conjunction with the operation of the ball batting rod 24 to open the entrance 35 of the feed path 41.
The valve 46 is vertically inserted into the chamber 43, and a contact portion 47 for the operating member 26 is formed at the lower end of the valve 46, and an opening/closing piece 48 for the inlet 35 is formed on the side edge of the valve 46. is formed and extends into the slit 45. Before operation, the control valve 46 is stopped at a lower end position where it is stopped by a stopper 49 at the lower end of the base body 34,
is open, and can be pushed up when the operating member 26 is tilted upward, and returned to its original state by its own weight when the operating member 26 is tilted downward. On the other hand, the second control valve 50
It controls the opening and closing of the outlet 42 of the feed path 41 by following the elevation and descent of the control valve 46, and is vertically inserted into the first valve 46 and connected in an uncoupled state, and the side of the first valve 50 On-off valve 51 for outlet 42 on edge
is formed and extends from the slit 44 into the feed path 41. Before operation, the control valve 50 is stopped at the lower end position where it is locked to the contact portion 47 of the first control valve 46 to close the outlet 42, and when the first valve 46 is raised, it is pulled up. 1st valve 4
During the descent of 6, it is possible to return to the descent by its own weight.

As shown in FIGS. 7a and 7b, both control valves 46 and 50 are synchronously interlocked with the movement of the ball hitting rod 24 by an amount S of elevation corresponding to the radius of the ball. Further, both opening/closing pieces 48, 51 are sized to be able to lock approximately the radius of the sphere, and a height difference H (smaller than the radius of the sphere) is provided between the upper and lower ends of each other. It rises and falls synchronously.

On the other hand, in the regulating portion 33B, the regulating lever 52 supported at the center of the base body 34 is connected to the control valve 4.
A regulation rod 57 for regulating the numbers 6 and 50 is articulated. The regulating lever 52 is brought into contact with and separated from the ball launching board 6 in connection with the opening and closing of the dish plate 5, and its center portion is connected to the both vertical support walls 38, as shown in FIGS. 2 and 4. A pin 53 is attached at the center between the two holes, and a first piece 54 extends toward the ball launcher 6. Note that the same lever 52 is connected to a spring 56.
(An example is shown in which the lever is hung between the upper end of the base body 34 and the second piece 55 of the lever 52.) It is biased counterclockwise in FIG. 4. On the other hand, the regulating rod 57 is suspended by a pin 58 attached to the tip of the second piece 55 of the regulating lever 52, and the regulating rod 57 is inserted into the chamber 43 from the hole 59 in the cover wall 37 of the base body 34. The locking ring 60 at the lower end is inserted into the second control valve 50 in the inner part so that the locking ring 60 at the lower end can be locked to the abutment part 47 of the first control valve 46 . Note that the rod 57 may be replaced with a string-like material.

Therefore, in the regulating portion 33B, when the plate plate 5 is in the closed state, the regulating lever 52 contacts the front surface of the ball launcher 6 and changes its tilt as shown by the imaginary line in FIG. When the regulating rod 57 is lowered to the lowest position and the first control valve 46 is held in the released state, and when the plate plate 5 is in the open state, the regulating lever 52 is moved by the spring 56 as shown by the solid line in the figure. As the ball is returned to the ball locking state, the regulating rod 57 pulls up the first and second control valves 46 and 50 to restrain the ball in the ball locking state.

In the main row pachinko machine configured as described above, when the plate plate 5 with the ball plate 13 attached thereto is held in the normal closed position, the ball feed regulating device 3
3 is in the released state as described above, in the ball feeding section 33A, the first and second control valves 46, 50 are closed as shown in FIGS. 5 and 7a.
is released from the regulating rod 57 and stopped at the lower end position, opening the inlet 35 to the feed path 41 and opening the outlet 4.
2 is held in a ball feeding standby state with closed.
Therefore, the pachinko balls thrown into the tray body 16 of the ball tray 13 are then passed through the alignment path 17 to the ball rectifier 27.
The ball passes through the rectifying path 29 of the ball, and then passes from the standby path 31 through the port 32 and the inlet 35 into the feed path 41, and the leading ball is locked in the opening/closing piece 51 of the second control valve 50. be done. As a result, the first ball
B ₁ is held in a restrained position just before exit 42, and is on standby road 3.
The second ball B ₂ in the first ball B 1 contacts the first ball B ₁ and waits at a position facing the entrance 35 , and thereafter moves toward the turning path 30 .
The inner ball B ₃ and the frontmost ball B ₄ in the rectifying passage 29 are accommodated in three diagonal stages, and the rectifying passage 29
A plurality of balls are housed in a row inside. Furthermore, the plate body 1
6 to the rectification path 29 is skillfully changed by the direction changing path 30, and the ball pressure acting on the first and second balls B ₁ and B ₂ is significantly reduced, so that both balls are B ₁ and B ₂ can be smoothly moved in and out.

When the firing device is operated in the above-described ball passing state, the first and second control valves 46 and 50 move up and down in conjunction with each other with respect to the ball batting rod 24, thereby feeding the ball. That is, in response to the elastic movement of the ball hitting rod 24, the first control valve 46 is directly pushed up via the operating member 26, and its opening/closing piece 48 instantly closes the entrance 35 of the feed path 41, thereby releasing the second ball. B ₂ is stopped in a state where it is slightly pushed back to the standby path 31, and in response to this, the second control valve 50 is pulled up by the first control valve 46 and its opening/closing piece 51 instantly opens the outlet 42 of the feed path 41. do. As a result, while the second ball B ₂ is held in the waiting path 31 , only the first ball B ₁ is released and falls from the exit 42 to the firing rail 7 side under its own weight, and is then sent to the firing site 8 . It is then placed in a standby position for a while (see Figure 7b). Note that the slight movement (return) of the second ball B ₂ is reasonably allowed due to the fluctuations of the third and fourth balls B ₃ and B ₄ .

Next, as soon as the first control valve 46 is released from the operating member 26 in response to the springing action of the batting rod 24, it returns to its original position under its own weight and closes the inlet 35 with its opening/closing piece 48.
At the same time, the second control valve 50 returns to its original position under its own weight in synchronization with the first control valve 46, and returns to the ball feeding standby state in which the outlet 42 is closed by the opening/closing piece 51. As a result, the second ball B ₂
is released from the opening/closing piece 48 on the first side and enters the feed path 4.
1, and the opening/closing piece 5 on the second side.
1 and waits at a position facing the exit 42 (see FIG. 7a). Thereafter, in conjunction with the operation of the ball batting rod 24, both control valves 46 and 50 are moved up and down to stop and feed the ball, and one ball is delivered to the firing site 8 in the preceding order.

As mentioned above, in the ball feeding section 33A, the ball hitting rod 24
During the upward movement of both valves 46 and 50 in time with the elastic movement of the opening/closing piece 48 on the first side,
After locking the ball inside, the opening/closing piece 51 on the second side releases the ball in the feeding path 41, so that only one ball is accurately sent to the firing part 8 side, and the two balls are Delivery is avoided. In addition, in the process of lowering the valves 46 and 50 in time with the springing action of the ball hitting rod 24, the opening/closing piece 51 on the second side first closes the outlet 42, and then the mallet 25 hits the ball at the firing site 8. When the ball is hit, the opening/closing piece 48 on the first side releases the ball in the waiting path 31, so that even if the ball passes quickly into the feeding path 41, it is stopped and waiting at the exit 42, and the ball is stopped at the exit 42 and sent to the firing site 8.
Sending to the other side is avoided in advance. Especially the first and second
Since the control valves 46 and 50 are connected to each other in a non-coupled manner, they can be moved up and down smoothly without interfering with each other, and ball jamming can be avoided. Furthermore, since the height difference H is set between the opening and closing pieces 48 and 51 on both sides, the ball can be restrained and released quickly and in a timely manner with a necessary minimum time difference between each other, and the ball can be hit with the height difference H. The lifting amount and lifting time of both control valves 46 and 50 relative to the operation of the rod 24 can be reduced, and stable and accurate ball feeding operation can be continued from beginning to end.

In this example pachinko machine, when the plate plate 5 equipped with the ball plate 13 is opened to inspect the inside of the machine,
As is clear from FIG. 4, as soon as the regulating lever 52 in the regulating portion 33B is separated from the ball launcher 6, it quickly returns to the ball stopping state shown by the solid line in the figure, and following this, the regulating lever 57 is raised. Ru. This causes the first control valve 46 to close to the regulating rod 5.
The second control valve 50 is engaged with the locking ring 60 of No. 7.
As shown in Figure 7b, the first
The ball in the standby path 31 of the ball rectifier 27 is restrained by the side opening/closing piece 48 in the ball stopping position where the inlet 35 is closed. When the plate plate 5 is set to the original closed position again, the regulating lever 52 and the regulating rod 57 are changed to the above-mentioned released state as shown by the imaginary line in FIG. Second control valve 4
6, 50 are lowered to their original positions where they can be interlocked with the operating member 26, and returned to the ball feeding standby state in which the outlet 42 is closed by the opening/closing piece 51 on the second side, as shown in FIG. The ball that has passed inside is stopped by the opening/closing piece 51 on the second side.

[Summary of the invention]

As can be understood from the above-described embodiments, the pachinko game machine of the present invention has a front frame that can be opened and closed, and receives the pachinko balls in the ball tray one by one on the back side of the tray plate equipped with the ball tray. It is equipped with a ball feeding part that sends out the ball to the firing part of the firing rail, and a regulating part that regulates the ball feeding part according to the open/closed state of the plate plate. Two control valves that alternately open and close the inlet of the communicating feeding section and the outlet of the feeding path facing the firing site are appropriately connected to the ball hitting means of the firing device, and are linked to the ball hitting means of the ball hitting means to open and close one of the two control valves. Ball feeding, that is, balls in the feeding path, is alternately changed between a ball feeding standby position where one control valve closes the outlet of the feeding path and a ball stopping position where the other control valve closes the feeding path entrance. The delivery of the ball to the launch site and the passage of the ball into the delivery path in the ball dish can be carried out stably from beginning to end, and the ball can be continued to be launched appropriately based on such ball delivery. .

In the above-mentioned regulating section for the above-mentioned ball feeding section, when the regulating lever comes into contact with the fixing member inside the front frame and changes in the releasing direction when the plate plate is in the closed state, the regulating member connected to the lever is moved. releases the control valve and returns it to the above-mentioned ball feeding standby position, and as the plate plate is in the open state, the regulation lever is separated from the fixing member and returned to the regulation direction, and as a result, the regulation member is released. Since the control valve can be engaged and restrained at the above-mentioned ball stopping position, it is possible to prevent the balls from falling out (outflow) in the ball tray equipped on the tray when the tray is open, and also When opening and closing the valve, interference and damage between the ball hitting means and the control valve can be avoided.

The technical concept of linking the regulation part to the ball feeding part mentioned above makes it possible to assemble both parts into one base or case body, which makes it possible to combine both into one and make it compact. It is also easy to configure it as a ball feed regulating device that is easy to handle.
