When this surface area (J) meets the operating pin 233 of the continuous channel lever 230, the continuous channel lever 230 has returned to its normal position, and the winning ball processing device 78 has the operating pin 78e of the continuous channel lever 230. 230 has been rotated back to a position where it touches the upper end edge of the engagement hole 232. At this time, the bottom surface of the concave hole 78c (FIG. 9(A)) of the winning ball processing device 78 substantially coincides with the top surface position of the downflow gutter 71a, and the winning ball flowing down on the downflow gutter 71a is placed in the concave hole. It is possible to flow down into 78c.

At this time, the detection piece 78d at the end of the winning ball processing device 78 is connected to the U-shaped detection portion 22 of the switch sensor 221 (SW□).
It is in a state where it has entered 1a. In this state, the concave hole 7
When a winning ball flows into the ball 8c, the weight of the winning ball causes the operating pin 78e to move into the engagement hole 232 of the continuous channel lever 230.
The winning ball processing device 78 rotates to a position where it touches the lower edge of the ball and stops at that position, and the winning ball processing device 78
The terminal detection piece 78d is the switch sensor 221 (SWl)
It is in a state where it has come out of the U-shaped detection section 221a inside. In this state, the tip side of the winning ball processing device 78 is tilted backwards, and the winning balls in the concave hole 78c move toward the exit, but at the exit, they flow down. The prize ball is retained in the concave hole 78c by being retained by a retaining piece 71c, which serves as a winning ball outflow prevention means, which is vertically installed at the end of the gutter 71a.

The surface area is the outer peripheral surface of the cam protrusion 145, which has an arc shape with a constant curvature having the smallest radius of curvature from the center.

This area is the operating pin 23 of the continuous channel lever 230.
3, the connecting channel lever 230 is in a state in which its distal end side is rotated in a downward direction by the spring 234.

Accordingly, the winning ball processing device 78
30 is released, and the lower end of the tip rotates under the weight of the winning ball in the concave hole 78c to a position where it touches the lower guide gutter 71b, and as a result, The winning ball in the concave hole 78c is released from the lock by the locking piece 71c and flows out onto the lower guide gutter 71b.

The surface area (N) is the outer peripheral surface of the arc-shaped cam projection 145 whose distance from the center increases rapidly in the counterclockwise direction. This surface area (nu) is the operating pin 2 of the continuous channel lever 230.
33, as the connecting cam 140 rotates clockwise, the connecting lever 230 is rotated in the direction in which its distal end side is raised, and the lower end edge of the engagement hole 232 pushes up the operating pin 78e. By being
The winning ball processing device 78 is rotated in a direction in which its tip side is pushed up, and is forcibly rotated back to a normal position.

The surface area (R) is the outer peripheral surface of the arc-shaped cam protrusion 145 having a constant curvature and having the farthest radial distance from the center.

This surface area (ru) is the operating pin 23 of the continuous channel lever 230.
3, the winning ball processing device 78 is forcibly maintained in the state returned to the normal position by the continuous channel lever 230. At this time, the operating pin 233 is in contact with the lower end edge of the engagement hole 232 of the continuous channel lever 230, and even if the winning ball on the downflow gutter 71a flows into the concave hole 78c, the winning ball processing device 78 remains in its normal position. is maintained in a stopped state. Preparation time for the next prize ball ejection process is gained, and even if winning balls are generated continuously and a large ball pressure is applied to the ball locking piece 78h of the winning ball processing device 78, the ball is surely returned to the normal position. It is now possible to do so. At this time, the detection piece 78d at the rear end of the winning ball processing device 78
is the U-shaped detection part 2 of the switch sensor 221 (SW engineering)
The state is restored during 21a.

The surface area (W) is the outer circumferential surface of the cam protrusion 145, which has a substantially linear shape in which the distance from the center rapidly decreases in the counterclockwise direction.

This surface area (wo) is the operating pin 23 of the continuous chamber lever 230.
3, the operating pin 233 rapidly descends to the position where it contacts the surface area 146 as the continuous cam 140 rotates clockwise, and the winning ball processing device 78 loses its own weight and the storage chamber on the terminal side. With the weight of the return weight ball 78g (FIG. 9(A)) housed in 78f, the distal end side is maintained at the normal position raised, and only the connecting channel lever 230 is rotated in the direction in which the distal end side is lowered. It is rotated back to the normal position. In the restored state, the winning ball processing device 78 has its concave hole 78c (FIG. 9(A))
The winning ball on the downflow gutter 71a is in the initial state in which it can flow into, and the operating pin 233 is located near the upper edge of the engaging hole 232 of the connecting channel lever 230 in a steady state,
The winning ball on the downflow gutter 71a falls into the concave hole 78c (Fig. 9(A)
), the winning ball processing device 78 is in the initial state where it can be rotated to a position where the operating pin 233 contacts the lower end edge in the engagement hole 232 of the connecting channel lever 230. Furthermore, this surface area (w) also has a hook-like function to prevent the motor 82 from reversing.

As shown by arrows in FIG. 7, the crank cam 130 and the continuous cam 140 have a rotation ratio of 1:1 between the gear parts 131 and 141, and the crank cam 130
The part of the cam groove 135 that is shifted approximately 15 degrees from the boundary between fully loaded (A) and (B) in the fully loaded (B) direction (clockwise direction) and the area (C) and (S) of the continuous cam 140. They mesh so that they meet the boundary of the two.

Next, the operation of these cams 130, 140, the evacuation case 77 that constitutes the winning ball processing device, and the winning ball processing device 78
The operation will be explained based on FIGS. 8 to 10.

First, a description will be given of the initial state in which the evacuation case 77 is on standby in preparation for the ejection of prize balls before the winning ball processing device 78 is activated.

Initially, as shown in FIG. 8(A), the crank cam 130
The detection part 134a of the detection piece 134 is the switch sensor 22.
3 (SW, ), and the detection part 143a of the detection piece 143 of the continuous cam 140 is in a state where it meets the switch sensor 222 (SW2), the motor 82 stops, and the crank cam 130 and the continuous cam 140 is in a stopped state. The starting end side of the full load (A) of the cam groove 135 formed in the crank cam 130 meets the operating pin 213 of the operating lever 210,
The evacuation case 77 that constitutes the prize ball ejecting device is shown in Fig. 10 (
As shown in A), the ball has returned to a steady state and is in a standby state in preparation for ejecting the prize ball. Also, the starting end side of the surface area (h) of the outer peripheral surface cam 146 formed on the crank cam 140 is shown in FIG.
), the connecting lever 230 meets the operating pin 233 of the connecting lever 230, and as shown in FIG.
Due to its own weight and the weight of the return weight ball stored in the storage chamber 78f on the rear end side, the winning ball processing device 78
Each has returned to its normal position, and at this time, the operating pin 78e of the winning ball processing device 78 is connected to the continuous channel lever 23.
It is in contact with the upper edge of the engagement hole 232 of No. 0. Also,
The detection piece 78d at the rear end of the winning ball processing device 78 is in a state where it meets the switch sensor 221 (SWl).

In this state, when the winning ball flowing down on the guide gutter 71a flows into the concave hole 78c of the winning ball processing device 78 (only one ball can enter), the weight of the winning ball that has flowed into the winning ball processing device 78 rotates clockwise in the figure, and as shown in Figure 9 (B
), the operating pin 78e stops in contact with the lower edge of the engagement hole 232 of the connecting channel lever 230. In the process of rotation, the detection piece 78d at the rear end of the winning ball processing device 78 separates from the switch sensor 221 (SW□), and at the time of separation, the output of the switch sensor 221 (SW, ) becomes "H".
(high) level, the output of the remote motor 82 is activated, and the crank cam 130 is rotated counterclockwise by this motor 82, and the continuous cam 140 is rotated clockwise, so that a series of prize balls are ejected as shown below. Processing is done. Until this process is completed, the winning balls in the concave hole 78c of the winning ball processing device 78 are lowered by the locking piece 71C at the tip of the downflow gutter 71a at the outlet, as shown in FIG. 9(B). The winning balls are prevented from flowing onto the side downflow gutter 71a.

From this state, the motor 82 causes the crank cam 130 to
is rotated counterclockwise, and the detection part 134 of the detection piece 134
a meets the switch sensor 223 (SW, ), the switch sensor 223 (SW, ) is turned on, and the continuous cam 140 is also rotated clockwise. Then, the operating pin 213 is lowered by the fully loaded cam groove 135 (a) formed in the crank cam 130, and the evacuation case 7
7 is the operating lever 210, the connecting rod 81, and the link 8
4, the ball is rotated counterclockwise as shown in FIG. 10(B), and the prize ball ejecting process is performed.

A cam groove 135 formed in the crank cam 130
Immediately before the starting end of the full load (b) meets the operating pin 213 of the operating lever 210, that is, immediately before the evacuation case 77 is rotated the most by the crank cam 130 as shown in FIG. The surface area of the outer peripheral surface cam 146 formed at 140 meets the operating pin 233 of the connecting channel lever 230, and the connecting channel lever 230 is rotated clockwise as shown in FIG. 9(C). The winning ball processing device 78 is further rotated clockwise due to the weight of the continuous lever 230 and the winning balls. Then,
The winning ball in the concave hole 78c, whose outflow has been blocked by the locking piece 71c at the tip of the downflow gutter 71a, is released from the locking by the locking piece 71c and flows out onto the lower downflow gutter 71b.

Thereafter, the full load (b) of the crank cam 130 meets the operating pin 213 of the operating lever 210, and the evacuation case 77 remains tilted as described above (sufficient time to eject the prize ball) for a while. At the same time, the continuous lever 230
The winning ball processing device 78 continues to rotate and tilt as shown in FIG. 9(C) for a while (sufficient time to eject the held balls).

On the other hand, when the winning ball processing device 78 continues to be in the most tilted state, the cam groove 13 of the crank cam 130
5 is in continuous contact with the operating pin 213 of the operating lever 210, and the evacuation case 77 continues to be tilted most counterclockwise for a while as shown in FIG. 10(B).

After a certain period of time has elapsed, the full load (c) of the crank cam 130 meets the operating pin 213 of the operating lever 210, and the surface area (nu) of the outer peripheral surface cam 146 of the continuous channel cam 140 reaches the operating pin of the continuous channel lever 230. 78e, the evacuation case 77 is returned to the steady state shown in FIG. The detection piece 78d at the rear end of the device 78 is returned to the state where it meets the switch sensor (SWl), and the full load (D) of the crank cam 130 is placed in the operating pin 21 of the operating lever 210.
3, and the surface area (R) of the outer peripheral surface cam 146 of the continuous channel cam 140 meets the operating pin 233 of the continuous channel lever 230.

The surface area (R) of the outer periphery cam 146 of the continuous channel cam 140 meets the operating pin 233 of the continuous channel lever 230, and the winning ball processing device 78 is forcibly maintained in a steady state by the continuous channel lever 230 for a certain period of time ( After the preparation time for the next prize ball ejection process has elapsed, the initial state shown in FIG. The surface area (H) of the outer peripheral surface cam 146 returns to the state where it meets the operating pin 233 of the connecting channel lever 230, and the evacuation case 77 returns to the steady state shown in FIG. 10(A).
The continuous channel lever 230 is returned to the steady state shown in FIG. The initial state is approximately tangent to the upper end of .

In this way, one prize ball ejection process is completed, and the crank cam 130, the continuous cam 140, the evacuation case 77,
When the winning ball processing device 78 and the continuous channel lever 230 return to the initial state, the detection part 143a of the detection piece 143 of the continuous channel cam 140 is activated by the switch sensor 222 (SW
2) and the sensor output becomes the "L" (low) level, the motor 82 is stopped and returns to the standby state in preparation for the next prize ball ejection process.

In the above, we have explained the one-time operation of ejecting the prize ball in a normal state, that is, a state where the guide gutter 73 is sufficiently filled with balls and a state where no balls are clogged in the guide gutter 73. The treadle lever 110 is used to stop the prize ball discharge when the ball is not sufficiently filled in the guide channel 73, or when the guide gutter 73 is clogged with balls.
The tip side of the locking piece 1 rises and the locking piece 1 is moved by the operation of the connecting rod 113.
14 is engaged with the engagement piece 77s of the evacuation case 77 to lock the tilting of the evacuation case 77, when a winning ball occurs, the evacuation case 77 and the winning ball processing device 78 are operated as follows. become. Initially, crank cam 130,
The continuous cam 140 is also in the state shown in FIG. 8 as before, and in this state, the winning balls flowing down on the guide gutter 71 are affected by the weight of the winning balls that have flowed into the concave holes 78c of the winning ball processing device 78. The winning ball processing device 78 rotates clockwise from the state shown in FIG. 9(A), and the operating pin 78e shown in FIG. 9(B) comes into contact with the lower end edge of the engagement hole 232 of the continuous channel lever 230. It stops in the state. As a result, the switch sensor 22
1 (SWl), the remoter 82 starts rotating. Then, the actuating pin 213 that meets the surface area (a) of the crank cam 130 attempts to rotate the actuating lever clockwise, but the locking pawl 114 engages with the engaging piece 77s of the evacuation case 77. Therefore, the rotation of the motor 82 is forcibly stopped, and the clockwise rotation of the actuating pin 213 is also stopped when it is in contact with the middle of the surface area (a) of the crank cam 130. In this state, the operating pin 233 of the continuous cam is in contact with the surface area (h), and the winning ball processing device 78 is stopped in the state shown in FIG. 9(B). At this point, the replenishing device is activated to replenish the balls, or the jammed balls are removed, and the tip side of the treadle lever 110 for stopping prize ball ejection is pushed down by the weight of the balls, so that the connecting rod 1
13 is activated, the locking pawl 114 disengages from the engagement piece 77s of the evacuation case 77, and the evacuation case 77 becomes tiltable, so that the motor 82 continues to rotate from the above state, A prize ball ejecting operation is performed. As mentioned above, the evacuation case 7
7 is locked, and the winning ball processing device 78 is maintained in the state shown in FIG. This can be prevented.

Detection section 143 of the detection piece 143 of the continuous cam 140
meets the switch sensor 222 (SW2) and the motor 8
2 is stopped, the detection part 134a of the detection piece 134 of the crank cam 130 detects the switch sensor 223 (S
Leave W3).

Next, based on FIGS. 11(A) and (B), two systems of ejection processing in the above prize ball ejection processing, that is, normal ejection processing (e.g.,
The timing and operation of the 13-piece discharge process) and the small-size discharge process (for example, the 7-piece discharge process) will be explained.

In this embodiment, the normal discharge process (for example, the 13-piece discharge process) is performed when a ball hits a winning area 5, 7, 8, etc. other than the winning space 21 of the variable winning device 10.

During this normal discharge process, the limit solenoid 92 is energized by the control means described later, and as shown in FIG. 11(a), (
By contracting the actuating rod 92a as shown by the solid line in b), the rotary lever 91 is rotated clockwise in the figure via the actuating lever 94, and the tip side of the flow prevention lever 93 The locking claw 93a comes off the evacuation case 77 and the ball sheath case 7
Since all of the prize balls (13 pieces) waiting during 7th are in a state where they can be released, the evacuation case 77 is
) from the state shown in Fig. 11 (B).
When the state shown in is reached, all of the prize balls (13 pieces) waiting therein are ejected.

Even when the prize ball ejection process is completed and the evacuation case 77 returns to a steady state, the limit solenoid 92 is still energized and the locking claw 93a of the falling prevention lever 93 has come out of the ball sheath case 77. Then, the evacuation case 77 is filled with the prize balls waiting in the guide gutter 73.

On the other hand, for small discharge processing (e.g. 7 pieces), in this example,
Winning area 26.2 in the winning space 21 of the variable winning device 10
This is done when a ball hits the 7th place.

During this small discharge process, the limit solenoid 92 is demagnetized by the control means described later, and as shown in FIGS.
The actuating rod 92a is connected to the spring 92 as shown by the chain line in FIG.
By being extended by the force b, the rotary lever 91 is rotated counterclockwise in the figure via the operating lever 94, and its locking claw 93a enters into the spherical sheath case 77, and the upstream side of the evacuation case 77 is rotated. The prize balls (6 pieces) are prevented from flowing out, and the ball sheath case 77 rotates counterclockwise from the state shown in FIG. 11(A) to the state shown in FIG. 11(B). When this happens, only the downstream prize balls (7 balls) out of the 13 prize balls waiting therein are ejected.

Then, when the ball sheath case 77 is returned to the steady state after the prize ball ejection process is completed, the limit solenoid 92 is energized by the control means described later and the rotation lever 93 is rotated clockwise just before the return. The locking claw 93a
escapes from the evacuation case 77, and the guide gutter 73 is quickly filled with spare balls as prize balls waiting on the guide gutter 73.

FIG. 13 shows a timing chart when discharging prize balls.

The limit solenoid 92 is always energized at the time of normal prize ball ejection which is carried out when a prize is won in the winning areas 4, 5, 7, 8.11 other than the winning areas 26, 27.27 in the variable winning device 10. , the locking claw 9 of the flow prevention lever 93
Since ball 3a has come out of the evacuation case 77, 13 batted balls are waiting in the ball sheath case 77 for normal ejection. And winning areas 4, 5, 7, 8
The ball that won in ゜11 is game board 11! & Side drainage gutter 7
1a flows down into the concave portion 78C of the winning ball processing device 78, and when the winning ball processing device 78 rotates one step in the direction in which its front side falls down due to the weight of the winning balls, the back of the winning ball processing device 78 The detection piece 78d at the end is the switch sensor 221 (S
When the switch sensor 221 (SW □) is turned on, its output becomes "H" (high) level and the motor 82 is driven.

When the motor 82 is driven, the crank cam 130 and the continuous cam 140 are rotated, and the detection portion 134a of the detection piece 134 of the crank cam 130 first meets the U-shaped detection portion 222a of the switch sensor 222 (SW2). The output becomes r) (J (high) level. After that,
As the winning ball processing device 78 is returned with the rotation of the continuous cam 140, the detection piece 78d at the rear end returns to the U-shaped detection part 221a of the switch sensor 221 (SW work), and , ) output is r
After that, the detection part 134a of the detection piece 134 of the crank cam 130 comes out of the U-shaped detection part 223a of the switch sensor 223 (SW3), and the sensor output becomes "L" (low) level. low) level. Then, when T

A small discharge (e.g., 7 pieces discharged) wins a prize in the winning areas 26, 27, 27 in the variable prize winning device 10, and the winning prize is transferred to the control device 40.
This is performed when the data is stored in the memory section 0. Switch sensor 221 (SWl), 2 during this small discharge
The rising and falling timings of the sensor outputs 22 (SW2) and 223 (SW, ) and the starting and stopping timings of the motor 82 are the same as in the above-mentioned normal discharge.

And, especially at this small ejection, winning areas 26, 27.2
The switch sensor 223 (SW
In synchronization with the "H" (high) level in 3), the limit solenoid 92 becomes "L" (low) level and becomes demagnetized, and the locking claw 93a at the tip of the flow prevention lever 93 enters into the evacuation case 77. Then, only some of the prize balls (for example, 7 balls) in the evacuation case 77 can be ejected.

Then, in this state, the evacuation case 77 is tilted by the crank cam 130 to perform a small ejection (e.g., ejecting 7 pieces), and the continuous cam 140 rotates once, causing the switch sensor 22
The evacuation case is removed by demagnetizing the limit solenoid 92 at the rising edge of the switch sensor 223 (SW3) T seconds before the output of SW2 (SW2) returns to the J low level and the motor 82 is stopped. The locking claw 93a at the tip of the falling prevention lever 93 is disengaged from inside the guide gutter 73 and the evacuation case 77 is replenished with spare balls as prize balls. That is, just before the evacuation case 77 finishes returning with the rotation of the crank cam 130, the locking claw 93a at the tip of the flow prevention lever 93 comes out of the guide gutter 77, and the spare ball as a prize ball is quickly inserted into the evacuation case 77. will be replenished. Then, when the continuous sensor 140 rotates once, the detection part 143a of the detection piece 143 meets the switch sensor 222 (SW,) and the sensor output reaches the "L" (low) level. At the falling edge, the above control is performed. The number of winnings stored in the storage section of the means (not shown) is counted down by "1".

Since the pachinko game machine according to this embodiment is configured as described above, the winning balls are placed in the concave hole 78c of the winning ball processing device 78.
When the ball enters, the winning ball processing device 78 is tilted one step and is locked to the continuous speed chamber lever 230, and the winning ball is locked by the locking piece 71c so that it does not flow out from the concave hole 78c. While the prize ball is locked, the prize ball is discharged, and after that, the prize ball processing device 78 is tilted to two stages together with the continuous channel lever 230, and the concave hole 78 is tilted to two stages.
8c, the winning balls are discharged onto the downflow gutter 71b of the winning ball processing device 78, and each winning ball can be reliably discharged. In conjunction with this, there is no need for a winning ball blocking member that causes winning balls to flow out.

In addition, a limit solenoid 92 that drives a locking lever 93 that changes the number of prize balls to be ejected and a switch sensor 223 (SW3) that operates the limit solenoid 92 are detachably attached to the back mechanism panel 80, and accessories such as An accessory control device 40 that corresponds one-to-one to the variable prize winning device 10)
Since it is connected to 0, the game board 1 that discharges prize balls in one system and the game board 1 that discharges prize balls in multiple systems can be exchanged, and the accessory control made in one-to-one correspondence with the game boards 1. Device 4
By exchanging 00, it becomes possible to replace a pachinko game machine that discharges one system of prize balls with a pachinko game machine that discharges multiple systems of prize balls, and the back mechanism panel 80 of the pachinko game machine can be used effectively.

In the above embodiment, the number of prize balls discharged during normal time is 13, and the number of prize balls discharged during small discharge is 7, but these numbers may be any number.

For example, if you want to make the number of prize balls ejected at the time of small ejection an even number such as 10, the locking pawl a of the locking lever 93 may be made step-shaped.

In addition, a locking piece 71c is provided at the tip of the downflow gutter 71a as a winning ball outflow prevention means, but the winning ball can be locked in the concave hole 78c when the winning ball processing device 78 is displaced by one step. Any means available may be used.

[Effects of the Invention] As described above, in the pachinko game machine according to the present invention, the game board having the game area and the accessory and the back mechanism board having the prize ball ejection processing mechanism can be detachably attached to the pachinko game machine main body. A prize ball discharge control board having a prize ball discharge control unit for controlling the prize ball discharge operation of the prize ball discharge processing mechanism is installed on the back mechanism panel, and also controls the accessory object. Since the configuration includes an accessory control device having an accessory control unit for discharging prize balls and a prize ball number control unit for changing the number of prize balls ejected by the prize ball ejection processing mechanism, one system of prize ball ejection can be performed. By replacing the game board with a game board that ejects multiple FA prize balls and replacing the accessory control device that is made in one-to-one correspondence with these game parts, a pachinko game machine that ejects one system of prize balls can be created. It becomes possible to replace the pachinko game machine with a pachinko game machine that ejects multiple systems of prize balls, and the back mechanism board of the pachinko game machine can be used effectively, thereby making it possible to effectively use the back mechanism board of the pachinko game machine.
