The diameter of the lamp socket plate 38 is slightly larger than the distance to the surface of the mounting member 36. Therefore, part of the lamp socket plate 38 falls into the opening 36B provided in the mounting member 36 and cannot be pulled out downward.

(B) Body The printed circuit board 43A is fixed in the body 42, and nine memory ball number indicating lamps 43, which are LEDs, are attached to the printed circuit board 43A. The memory ball number display lamp 43 and the in-head lamp 37 are drawn out from the opening 30B of the rear frame 30.

(C) Guide wall for legs In order to facilitate the movement of the legs 45 moving in the front-rear direction of the recessed chamber 20, the rear frame 30 is continuously connected to the legs 30 through openings 30C through which the legs 45 pass. Movement guide wall with a vertical U-shaped cross section relative to section 45
47 is provided.

Drive device frame (a) Drive of legs The drive device frame 50 has the ears 50A of the boss 3 of the rear surface frame 30.
Screwed to 9. The leg portion 45 of the background model 40 is reciprocated in the front-rear direction of the recess chamber 20 by a motor 51 with a speed reduction mechanism provided below the drive device frame 50 via a crank mechanism.

More specifically, the motor 51 is fixed to the mounting plate 52 fitted and fixed to the back surface of the drive device frame 50 with screws 51B from below,
The output shaft 51A extends upwardly for a long time, and the upper end of the output shaft 51A has a drive device frame 5
It is supported by a bearing plate 53 fixed to the back surface of 0. The first drive gear 54 is screwed to the lower part of the output shaft 51A,
The first drive gear 54 meshes with a driven gear 57 that is pivotally supported by a shaft 56 that hangs on a shelf frame 55 provided in the middle of the back surface of the drive device frame 50. A shaft 57A is provided on the lower surface of the driven gear 57 at a position shifted outward from the center of the shaft, and the shaft 57A and the shaft 45A provided inside the rear end of the leg portion 45 of the background model 40 are interlocked. Rod 5
Linked at 8. The driven gear 57, the interlocking rod 58,
The leg 45 is reciprocated by the crank mechanism of the leg 45.
As shown in Fig. 10, this crank mechanism is the first drive gear.
The positions of shafts 57A of driven gears 57, which are provided on both sides of 54 and pivotally support the left and right interlocking rods 58, are different from each other by 180 degrees. Therefore, the left and right legs 45 alternately project and retract.

(B) Head drive The output shaft 51A of the motor has a second drive gear 5 at the upper end thereof.
The second driving gear 59 is meshed with the gear 34 of the background model head described above. Therefore, the head portion 41 of the background model 40 is rotated in synchronization with the leg portion 45 of the background model 40 protruding and retracting due to the rotation of the output shaft 51A of the motor. Background model 40 with second drive gear 59
In order to detect the position where the head 41 of the robot is turned 180 degrees and stop it at that position, a cam barrel 60 is screwed to the output shaft 51A of the motor in the middle, and the shaft is attached to the peripheral surface of the cam barrel 60. Notches 61A and 61B are provided symmetrically and vertically, and the notches 61A and 6B are provided.
The actuators 62A and 62B of the position detector 62 composed of two-circuit micro switches are assigned to 1B. The micro switch is attached to the shelf frame 55 by a holder 63 formed integrally with the shelf frame 55 for easy positioning.

Movement of the movable body of the background model (a) Movement of the first movable body When the two legs 45 of the background model 40, which is the first movable body, do not move only linearly, but project to the front side, The two move forward while curving in the direction in which they approach each other.

More specifically, FIG. 10 (A) shows the time when the actuator 62A of the position detector 62 falls into the notch 61A of the cam cylinder 60 which is rotationally driven in one direction (direction of arrow A) by the motor 51. Indicates. At this time, the left and right legs 45 are stationary at the same position as seen in the front-rear direction of the recess 20.

Now, when the motor 51 is started, the actuator 62B of the position detector 62 in the central first drive gear 54 has the notch 61B of the cam barrel 60.
The driven gear 57 rotates about 180 degrees in the B direction until the driven gear 57 falls.

During this time, first, when the driven gear 57 rotates about 45 degrees in the B direction, the interlocking rod 58 moves the left leg portion 45 forward in the arrow C direction and the right leg portion 45 retracts in the arrow E direction. , Which are the positions indicated by the solid lines in FIG. 10 (B). Driven gear 57 is about 45
When it is rotated in the B direction only once, the left leg 45 moves forward a little while keeping the solid line shape, and the right leg 45 moves backward a little while keeping the solid line shape. The left interlocking rod 58 is the frontmost position, the right interlocking rod 58 is the last position, and the moving direction thereafter is reversed in the D direction and the F direction. That is, the left leg 45 is retracted, and the right leg is
45 switches to the forward direction.

When the driven gear 57 further rotates about 45 degrees, the left interlocking rod 58 moves from the frontmost position to the D direction, and the right interlocking rod 58 moves from the last position to the F direction to the position indicated by the broken line in FIG. 10 (B). Become. In this case, the position of the pivot shaft 45A at the tip of the interlocking rod 58 hardly changes, while the position of the pivot shaft 57A at the rear end moves beyond the rotation center shaft 56 of the driven gear 57 and moves to the opposite side. As for 45, as it moves backward, it is displaced in the direction parallel to the movement guide wall 47 as shown by the broken line (around the axis 45A in FIG. 10 (B)).
And the right leg 45 is displaced toward the inside while moving forward (rotating counterclockwise around the shaft 45A in FIG. 10 (B)).

After that, the left leg 45 continues to move backward, the right leg 45 continues to move forward, and when the left and right legs 45 are aligned, the actuator 62B of the position detector 62 falls into the notch 61B of the cam barrel 60 and the motor 51
Stops.

(B) Movement of the second movable body The head 41 of the background model 40, which is the second movable body, is the leg portion.
In synchronism with the forward or backward movement of 45, it is rotated 180 degrees and the surface facing the recessed chamber 20 is inverted. That is, when the second drive gear 57 is rotated together with the first drive gear 54 by the motor 51, the gear 34 meshing with the first drive gear 54 rotates around the tubular member 35 via the bearing ring 34A, and the background model. At the position where the semi-transparent part 41A and the opaque part 41B of the head 41 of the 40 are reversed, the motor is just
51 stops.

As described above, the leg part 45 moves forward while being drawn inward, and draws a movement trajectory that curves toward the special winning opening 19 in the center, so it is won in the device and dropped onto the leg part 45 from the diversion shelf 22. The game balls will be actively collected in the special winning opening 19 by the legs 45. Therefore, not only the movement of the first movable body and the second movable body, but also the winning probability for the special winning opening 19 and the interest of the pachinko game are enhanced.

Further, since the substrate frame 10, the rear surface frame 30, and the drive device frame 50 are configured as a single unit and are separable,
Easy to assemble and repair.

Next, an example of a pachinko machine to which the above-mentioned variable prize device 1 is applied will be described.

In FIG. 11, the above-mentioned variable prize winning device 1 is disposed substantially at the center of a game area 2A defined by a guide rail 3 of a game board 2. Further, in the game area 2A, general winning devices 4, 5, guiding nails (not shown), windmill 6, out hole 7
Etc. are provided. Below the variable winning device 1, a total of three specific winning ports, that is, left and right first specific winning ports 8, 8 and a central second specific winning port 9 are juxtaposed. A first operation detector (first operation switch SW1) belongs to the first specific winning opening 8 and a second operation detector (second operation switch SW2) belongs to the second specific winning opening 9. There is.

In FIG. 12, 63 is a winning ball gathering gutter for the variable winning device 1, and with this winning ball gathering gutter 63, a winning ball from the normal winning hole 18 of the varying winning device 1 and a special winning hole 19 are special. The winning balls dropped through the prize detector 64 are collected in the count detector 65, and the total is counted.

Control Device The control operation of this pachinko machine will be described below with reference to the circuit diagram of FIG.

Reference numeral 70 is a reference time generation unit having a clock oscillation circuit 71 and a counter circuit 72. The counter circuit 72 includes a multistage frequency divider for the oscillation clock and a logic circuit connected to the frequency divider, and receives the oscillation clock to generate seven kinds of time signals T0 to T6 necessary for operation. There is. T0 is 0.8
Seconds, T2 is 3.2 seconds, T3 is a time signal with a repetition period of 0.1 seconds, T1 is 1.3 seconds later, T4 is 1.6 seconds later, T5 is 16.8 seconds later,
T6 is a time signal that rises after 29.6 seconds.

 Next, the operation will be described.

Control of Normal Game State Normally, the opening / closing blade 12 closes the variable winning device 1 with respect to the game ball. However, when a hit ball is won in the specific winning openings 8 and 9, the solenoid SOL is actuated in the following manner, and the opening / closing blade 12 opens the ball easily from a closed state (Fig. 1) in which no game ball is won. It is converted to the state (Fig. 6).

(B) Winning the first special winning opening The first winning detecting switch SW after winning the special winning opening 8
When 1 is turned ON, the flip-flop FF1 is set via the waveform shaping circuit 73, and its output terminal Q is inverted to H level and L level. As a result, on the other hand, the flip-flop FF6 is set via the falling differentiating circuit 74 and the OR gate 75, and the output terminal of the flip-flop FF6 becomes L level, thereby releasing the reset state of the effective time generation timer 76 composed of a counter. The timer 76 starts the clock operation of the time for treating the winning ball as valid. The flip-flop FF6 is returned to the reset state via the OR gate 77 when the timer time is up. On the other hand, until then H
The output of the AND gate 78 in the level disappears, and the OR gate 7
The reset state of the counter circuit 72 is released via 9 and the counting operation of the counter in the counter circuit 72 is started.

As shown in FIG. 14 (a), an output pulse (T3) is generated at the output terminal Q3 of the counter circuit 72, and the lamp 37 in the head 41 of the background model 40 is driven for 0.1 second via the lamp drive circuit 80. Is lit in the blinking cycle of. In addition, when 0.8 seconds has elapsed after the start of counting, the output pulse (T
0) occurs and is sent to the solenoid drive circuit 83 as the blade operation signal S0 through the two-input AND gate 81 and the OR gate 82 which are opened by the output of the flip-flop FF3, and the solenoid SOL is energized. The blade operation signal S0 is shortened to a width of 0.5 seconds for the following reason, and causes the opening / closing blade 12 to open / close once.

That is, when 1.3 seconds have passed from the start of counting, the counter circuit 72
An output pulse (T1) shown in FIG. 14 (a) is generated at the output terminal Q1 of the flip-flop FF1 and the reset terminal of the flip-flop FF1 via the two-input AND gate 84 and the OR gate 85 opened. Join and reset it to the initial state. When the flip-flop FF1 is reset, the output of the flip-flop FF1 returns to the H level, the output of the AND gate 78 goes to the H level, and the counter circuit 72 returns to the reset state.

(B) Winning in the second specific winning opening The second specific winning opening 9 is won, and the second operation detection switch
When SW2 operates, the opening / closing wing 12 performs the opening / closing operation only twice under the control described below.

First, when the second operation detection switch SW2 operates, the flip-flop FF2 is set through the waveform shaping circuit 86. The flip-flop FF1 is also set by the Q output of the flip-flop FF2, and the reset state of the counter circuit 72 is released. Therefore, the process in which the blade operation signal is generated 0.8 seconds after the start of counting and the opening / closing blade 12 opens and closes once is the same as in the case of winning the first specific winning opening.

However, in the case of winning the second specific winning opening, the output of the flip-flop FF2 becomes the L level, so the two inputs A
ND gate 84 is closed. Therefore, even if the output pulse (T1) shown in FIG. 14 (a) is generated at the output terminal Q1 of the counter circuit 72 after the lapse of 1.3 seconds, the two-input AND
Gate 84 does not accept this. Therefore, the counter circuit
The count of 72 advances, and 3.2 seconds after the start of counting, the counter circuit 72
An output pulse (T2) shown in FIG. 14 (b) is generated at the output terminal Q2 of. This pulse is applied to the reset input terminal R of the flip-flops FF1 and FF2 through the OR gate 85, and resets both flip-flops FF1 and FF2. Since the outputs of both flip-flops FF1 and FF2 return to the H level, the output of the AND gate 78 goes to the H level, and the counter circuit 72 returns to the reset state.

Until this counter circuit 72 returns to the reset state,
As shown in FIG. 14 (b), the output terminal of the counter circuit 72
The second pulse is generated at Q0, and the two-input AND gate 78,
Through the solenoid drive circuit 83, the solenoid SOL is energized for 0.8 seconds. Therefore, the opening / closing blade 12 performs opening / closing operation twice in total.

Special mode Conversion to game state During the period when the opening / closing blade 12 is performing one or two opening / closing operations as described above, a ball that wins with the opening / closing blade as a guide is a special winning of the variable winning device 1. When the player wins in the mouth 19 and is detected by the special winning switch SW3, the opening / closing operation is continued up to 18 times. In order to convert to this special mode game state, in the circuit of FIG.
While the FF6 maintains the set state, the game ball wins the special winning opening 19 and the special winning switch SW3 is turned on,
To be more precise, it is necessary that the special winning switch SW3 be turned on while the AND gate 88 is opened by the output of the flip-flop FF6 provided through the OR gate 89.

(A) Start of wait time When the special winning switch SW3 is turned on, a pulse is applied to the AND gate 88 via the waveform shaping circuit 87. AND gate 88 is now open by the Q output of flip-flop FF6. Accordingly, the pulse passes through the AND gate 88 and is applied to the flip-flop FF3 to set it, so that the Q output of the flip-flop FF3 goes high and the output goes low. At this time, this pulse causes the flip-flop FF6 through the OR gate 77, the counter circuit 72 through the OR gate 79, and the flip-flops FF5 and FF7 through the OR gate 91 to be in the initial state.

Flip-flop FF3 is set and its output is L
By inversion to the level, the reset state of the counter circuit 72, the flip-flops FF4, FF5, FF7, and the right number counter 92 is released. The counter circuit 72 starts its counting function, and each flip-flop FF4, FF5, FF7 is in a state in which it expects that a pulse will be sent from the counter circuit 72. That is, a "wait time" of 1.6 seconds to be described later starts.

(B) Operation of background model The position detector 62 belonging to the cam barrel 60 is shown in FIG.
As shown in FIG. 10, in the initial state, the position detection switch SW5 of the upper actuator 62A is OFF and the position detection switch SW6 of the lower actuator 62B is ON. When the lower position detection switch SW6 is ON, the waveform shaping circuit 107 and
The AND gate 102 is opened through the OR gate 101. Therefore, when flip-flop FF3 is set, its Q
The output is applied to the motor drive circuit 105 through the AND gate 102 to drive the motor 51. Therefore, the head 41 of the background model 40 rotates 180 degrees and stops. During this time, background model 4
The left and right legs 45 of 0 make a protruding and retracting motion, and stand still at the same position. The head 41 of the background model 40 is inverted and its semi-transparent portion 41A faces the concave chamber 20 side, so that the player can visualize the lamp 37 inside the head. This allows the player to know that the game has shifted to the special prize mode.

The right count counter 92 causes the right count display 25 to display “1” via the decoder 93.

(C) Temporary prohibition of opening / closing operation During the wait time as shown in Fig. 14 (c),
The opening / closing operation of the opening / closing blade 12 is temporarily prohibited. This is because the AND gate 81 is prohibited by the output of the flip-flop FF3.

(D) End of wait time When 1.6 seconds has elapsed after the start of counting, a pulse (T4) is generated at the output terminal Q4 of the counter circuit 72, and the pulse is input to the clock input terminal of the flip-flop FF7, and the flip-flop is turned on. FF7 is set. That is, the output of the flip-flop FF7 is switched to the L level and the Q output is switched to the H level. AND gate by the Q output of flip-flop FF7
109 is opened. The pulse generated at the output terminal Q0 of the counter circuit 72 is inverted via the inverter 110, and the inverted signal is applied to the solenoid drive circuit 83 through the AND gate 19. Thereby, the continuous opening / closing operation of the opening / closing wing 12 is started for the first time. In other words, the opening / closing blade 12 maintains the closed state as shown in FIG. 1 until 1.6 seconds elapses after the start of counting.

When the output of the flip-flop FF7 drops to L level, the reset state of the winning ball number display circuit 97 is released. Further, the Q output of the flip-flop FF7 also opens the AND gate 88 through the AND gate 90 and the OR gate 89.

Control of Special State Game State After the conversion to the special state game state, the opening / closing wing 12 performs the opening / closing operation up to 18 times. Here, "maximum" 18 times is written as 18 times is a unit cycle of a special mode game, one cycle, and during this cycle, when the special winning opening 19 is further won, even if the opening / closing blade 12 This is because the cycle is interrupted and the first cycle of the next new cycle is started even before the 18 times of opening / closing operations have been completed.

For example, when the special winning switch SW3 is turned on again after the twelfth opening / closing operation is finished and the next cycle starts, the next thirteenth opening / closing operation is not the thirteenth time of the previous cycle but the first update cycle. Further, this update cycle number, that is, the right exercise count “q” of the special mode game is allowed up to 8 cycles (q = 8) in this example. Therefore, if the maximum number of opening / closing operations of 18 times in each cycle is observed, 18 × 8 opening / closing operations can be expected, but conversely, even in the first cycle, the prize at the special winning opening 19 is won. If not, it is designed to end in that cycle. Further, in the present control device, even if the number of winning balls to the normal and special winning openings 18 and 19 reaches a predetermined number (10 in this example), the cycle is finished.

(B) Operation before update As described above, when 1.6 seconds (way time) has elapsed after the start of counting, the signal is generated at the output terminal Q0 of the counter circuit 72.
The inverted signal of the pulse every 8 seconds passes through the AND gate 109,
Applied to the solenoid drive circuit 83. The solenoid SOL is energized for each pulse of this inversion signal, and the opening / closing blade 12 repeats a maximum of 18 continuous opening / closing operations in the first cycle.

Winning Number Display During this opening / closing operation, many gaming balls win the variable winning device 1 through the opening / closing wings 12. The total of the winning balls is counted by the count switch SW4, and it is checked whether it is within a predetermined number. In detail,
The winning balls that enter the variable winning device 1 are normally winning holes 18
Regardless of whether it is a winning ball from or a winning ball from the special winning opening 19, it is collected in the count switch SW4 on the back surface of the game board and turns on the count switch. Every time the count switch SW4 is turned on, through the waveform shaping circuit 95,
One pulse is input to the winning ball number display circuit 97 including a counter. A counter (not shown) of the winning sphere number display circuit 97 is sequentially advanced by one step, and a total of nine LEDs 1 to LE as a winning sphere number display 43 via a decoder and a driver (not shown).
D9 lights up sequentially, and the number is displayed according to the number of lights.

Operation of the background model When the number of winning prizes reaches half of the predetermined number, here five, the detection signal from the winning ball number display circuit 97 causes the OR gate 10
It is input to the flip-flop FF4 through 0, and the flip-flop FF4 is set. Also, the opening / closing operation of the opening / closing blade 12 is 1
The output terminal Q of the counter circuit 72 even when it is performed up to 0 times.
An output pulse (T5) is generated at 5, causing flip-flop FF4 to set via OR gate 100. This set output activates the motor 105 through the OR gate 101, the AND gate 102, the OR gate 104, and the motor drive circuit 105. Therefore, unless the flip-flop FF4 is reset, the rotating operation of the head 41 and the projecting / retracting operation of the legs 45 of the background model 40 are continuously performed. As described above, when the predetermined conditions (the number of winnings is 5 or the operation of the opening / closing blades is 10 times) are satisfied, the background model is continuously operated to flow down the diversion shelves. By matching the timing of falling into the flow space and the timing of the leg portion 45 projecting forward, the chance of continuation can be increased.

(B) Renewal of the cycle Under the constraint of the total number of winning balls of 10 in the above 1 cycle, and before the above 18 times of opening and closing operations are completed, fortunately, the special winning opening 19 If there is a winning ball in, it will be updated to a new cycle. If the special winning switch SW3 detects again during this new cycle, this cycle is updated to the next cycle by the same operation as described above. Otherwise, the winning ball number display circuit 97 displays the pulse number "1".
When "0" is counted, the state returns to the initial state with the end of one cycle of the circuit. Head 41 and legs 45 of the background model 40 above
The continuous operation of (3) also informs the player that the special prize mode ends if there is no winning ball in the special winning opening 19 as it is.

Now, as shown in FIG. 15, fortunately, during the first cycle, when the special winning switch SW3 is turned on, the pulse generated in the AND gate 88 at this time causes the counter circuit 72, the flip-flop FF7 and the number of winning balls. Each of the display circuits 97 is once returned to the initial state and the wait time is entered. By resetting the flip-flop FF7, as in the transition to the special mode game state in the middle, the opening / closing operation of the opening / closing blade is temporarily prohibited, the background model 40 is stopped at a predetermined position after rotating 180 degrees, and the like. In this way, the weight time serves to return the movable pair provided in the concave chamber to the initial state, or to secure the time required for discharging the winning ball and operating the prize ball. By resetting flip-flop FF7, the number of winning balls indicator 4
3 is reset and all the LEDs of the winning ball number indicator 43 are turned off. Further, the pulse generated in the AND gate 88 is added to the right count 92, and the content of the counter is decremented by 1, so that the right count display 25 is switched from "1" to "2". As a result, the first cycle G is interrupted and updated to the second cycle, and the content displayed on the number-of-rights display 25 indicates the number of times the rights have been exercised.

This is the same when the special winning opening 19 is won again in the transition to the second cycle, and the operation is repeated in the same manner. At that time, each renewal point, that is, the end of each cycle, is clearly perceived by the player by the wait time in which the opening / closing wing 12 is closed for 1.6 seconds. In addition, special prize switch
At the same time as the cycle is updated every time SW3 is detected,
The right counter 92 advances its contents for a while.

Fortunately, if it is updated up to the final cycle, the eighth, the special opening / closing operation of the total of 18 times as promised in the cycle or the generation of a total of 10 prize balls will occur. The game state is completed.

That is, when the special winning opening 19 is won in the middle of the seventh cycle, the content of the number-of-rights counter 92 becomes "8", and the number-of-rights indicator 25 becomes "8" to indicate that it is the final cycle. , The output of the inverter 94 connected to the counter drops to L level. Therefore, in the eighth cycle (final cycle) currently in progress, the AND gate 88 does not accept the ON signal of the special winning switch SW3 thereafter.

When a total of 18 opening / closing operations promised in the eighth cycle have been performed, the counter circuit 72 sets the time when the total of 18 opening / closing operations are completed, more precisely, at the time when 29.6 seconds have elapsed after the start of counting, A pulse (T6) is generated at the output terminal Q6. or,
If a total of 10 winning balls are generated, the winning ball number display circuit
The end signal is generated in the decoder in 97. These pulses or signals are passed through the OR gate 108 to flip-flop F
Reset F3. The output of flip-flop FF3 is H
By returning to the level, the counter circuit 72, the flip-flops FF4, FF5, FF7, the right number counter 92, and the winning ball number display circuit 97 are reset. Further, the AND gate 106 is opened by the output of the flip-flop FF3. Therefore, if the background model 40 is not in the initial position, the ON signal of the position detection switch SW5 enters the AND gate 106 from the waveform shaping circuit 106, and the motor 51 operates via the OR gate 104 and the motor drive circuit 105, It is returned to the initial position. Since the Q output of the flip-flop FF3 is L level, the AND gate 102
Is prohibited.

Thus, the entire circuit system is returned to the initial state, and the pachinko machine is changed from the special mode gaming state to the normal gaming state.

Forcible switching to the normal game state When a certain cycle in the middle is finished without being updated, that is, a total of 1 with 1.6 seconds as one opening / closing operation unit
When the opening / closing operation of eight times is completed, a pulse is generated at the output terminal Q6 of the counter circuit 72 at a time point 29.6 seconds after the start of counting by the counter circuit 72, and as described above, the entire circuit system is operated. It is returned to the initial state, the special mode game state is forcibly released, and returns to the normal game state. Therefore, after that, unless a series of operations from winning the first and second specific winning openings 8 and 9 is performed, the special mode game state cannot be achieved. The disadvantageous situation for the player occurs because there is no winning in the special winning opening 19 after that in one cycle in which the above-mentioned 18 times is set as one unit.

On the other hand, during the opening and closing operation, a large number of game balls enter the variable winning device 1 through the opening and closing blades 12, and when the total number of the winning balls reaches 10, the winning ball number display circuit 97 The content becomes "10". Therefore, an end signal is generated in the decoder in the winning ball number display circuit 97, and the flip-flop FF3 is reset through the OR gate 108. Therefore, the special mode game state is forcibly released.

(Effects of the Invention) According to the present invention, a game ball that jumps into the device and flows down in the middle of the flow path of a plurality of game balls in the variable winning device operates when a predetermined game condition is satisfied. By contacting the movable body and increasing the winning probability to a specific winning hole of the above-mentioned plural kinds of winning holes, compared to the conventional device, a more advantageous state for the player appears and the pachinko game is more interesting. To be enhanced.
