I have. 63 is a hit judging means, which reads the signal from the random number judging means 57 and the signal from the stop control means 62, and determines whether or not all the symbols displayed on the three symbol display sections 22, 23, 24 match. Is determined.

Reference numeral 64 denotes right generating means for generating a right state advantageous to the player when the hit judging means 63 judges a hit. The right-generating means 64 generates a large winning prize each time the detection switch 56 detects the game ball B in the branch passage 50 on the hit side after the hit determination and one game ball B enters the upper right prize winning means 13 of the game board 5. The opening and closing plate 18a of the means 18 is opened for a predetermined time, and the opening and closing operation of the
It is designed to be repeated many times.

The special winning means 18 includes left and right symbol display sections 22 and 2
The opening / closing plate 18a is opened for a required time when the stop symbol after the fluctuation of 3 displays a predetermined hit symbol, for example, a combination symbol of "7.7.7". The counting means 59, the position setting means 60, the position determining means
61, by the stop control means 62, the game ball B different from the random number processing
The control means 65 for operating the symbol display section 24 by the above processing is constituted.

Next, the control operation of the pachinko machine will be described. In the game, when the operating handle 10 of the firing means 9 is operated, the game balls B are supplied one by one to the firing position of the firing rail in conjunction with the firing operation of the firing means 9, and the game balls B are moved along the guide rail 11. To sequentially fire on the upper side of the game board 5. Then, while the game ball B fired on the upper side of the game board 5 falls along the surface of the game board 5 and the game ball B enters the starting gate 19, the random number processing means 25 is activated. The symbols on the left and right symbol display portions 22 and 23 are changed, and when a predetermined change time elapses, each symbol display portion 22 and 2 is changed.
Stop symbol 3

At this time, the variation and stop control of the symbol display sections 22 and 23 is performed by reading a random number when the game ball B enters the starting gate 19 and processing the random number by the random number processing means 25. When a predetermined random number value is determined in advance, the symbols in the symbol display portions 22 and 23 match,
Symbols such as "0.0,""1.1,""2.2," and "9.9" are displayed.

Each of the left and right symbol display units 2 from the random number processing means 25
When a random number that matches the stop symbols of 2,23 is generated, the symbols on the left and right symbol display sections 22,23 fluctuate for a predetermined time, and then both stop at the same time or with a slight time difference, and The same symbol, for example, “3.3” is displayed on each symbol display section 22, 23. Therefore, in this case, if the symbol in the central symbol display section 24 becomes "3", it becomes a hit and a right state occurs.

On the other hand, when the symbols in the left and right symbol display portions 22 and 23 reach the "3/3" reach state, the random number at this time is determined by the random number determining means 57 and an operation command is sent to the opening / closing means 27. Since the output is performed, the opening / closing claw 30 of the opening / closing means 27 repeats the opening / closing operation intermittently a predetermined number of times. For example, open for 0.9 seconds,
This closing and opening operation is repeated six times, with one closing operation for 0.25 seconds. When the opening / closing means 27 is opened, the pair of opening / closing claws 30 open left and right, so that the game ball B can easily enter.

In the distribution means 26, the rotating body on the support plate 33
35 is driven around a rotation axis 45 by a stepping motor 44, and is always rotating in the direction indicated by the arrow a, and each light emitting diode 48 on the lower side of the turning rail 34 is synchronized with the rotation speed of the rotating body 35. Flashing to rotate. Also, at this time, if the stop symbols of the left and right symbol display portions 22 and 23 of the variation symbol display means 16 are “3.3”, when the game ball B enters the ball entry portion 43 of “3”, the variation symbol is displayed. Since the display symbols of the three symbol display portions 22, 23, 24 of the symbol display means 16 are all "3" and a winning right state occurs, the light emitting diode 48 on the lower side of the rotating body 35 Blinks in synchronization with the rotation of the rotator 35, that the ball entry portion 43 to be aimed at by the player is “3”, and where the rotation position of the ball entry portion 43 of “3” is Or display.

In this way, the opening / closing claw 30 of the opening / closing means 27 intermittently repeats the opening / closing operation, and the rotating body 35
When one of the game balls B enters the entrance 29 while the ball rotates, the detection switch (not shown) in the opening / closing means 27 causes the game ball B to enter.
Is detected.

Then, in response to a signal from the detection switch, the symbol in the central symbol display section 24 of the variable symbol display means 16 starts to vary, and the opening / closing claw 30 is closed, so that the subsequent game ball B enters. Block the ball. For this reason, distribution means
The number of game balls B entering 26 can be limited to one.

A game ball B which has entered the entrance 29 of the opening / closing means 27
When falling from the ball drop passage 38, the distribution top 39
Thus, the ball is distributed to the left and right ball guide passages 36, 37 at a ratio of about 1: 5. Therefore, a game ball falling from the ball drop passage 38
Most of the ball B enters the case body 32 of the sorting means 26 from the right ball guide passage 37 via the inclined passage 41, and turns on the turning rail 34 on the support plate 33 in the direction indicated by the arrow a.

The game ball B on the swivel rail 34 circulates on the swivel rail 34 at a speed corresponding to the inertia force when passing through the ball drop passage 38 and the inclined passage 41 from the entrance port 29, and gradually during this time. Stall. When the game ball B stalls, the game ball B
Is any of the recesses 34a formed on the inner peripheral side of the turning rail 34.
From above, rolls on the rotating body 35 in a rotating state,
Upon hitting the ball 42, it jumps on the rotating body 35 and is distributed into any one of the ten ball entry portions 43 to enter the ball.

The game ball B that has entered the ball entry section 43 of the rotating body 35 is
Then, the rotating body is supported by the lower support plate 33.
35 moves in the direction of the arrow A together with the
Corresponding to the falling hole 46 on the front side of the
It falls from 43 through the drop hole 46 to the lower branching means 51 side,
The detection switch 55 detects the game ball B.

The stepping motor 44 is a motor driving means 58
, And rotates the rotating body 35 in the direction indicated by the arrow a. During the operation of the stepping motor 44, the counting means 59 sequentially counts the pulses from the motor driving means 58, and measures the rotational position of the rotating body 35 based on the number of pulses. When the detection switch 55 detects the game ball B, the position discriminating means 61 reads the number of pulses from the counting means 59, and the number of pulses is read by the position setting means 60 to each of the ball entry sections 43.
Compared with each set pulse number set for each,
The position of the ball entry section 43 in which B has entered is determined.

In this case, since the rotating body 35 is rotating,
There is a time lag between the time when the detection switch 55 detects the game ball B and the time when the position determining means 61 reads the number of pulses from the counting means 59. However, since the stepping motor 44 is constantly rotating at a constant speed, if the time lag is corrected at the time of processing by the position determining means 61, the number of pulses from the counting means 59 and the number of pulses set by the position setting means 60 will be reduced. By comparing the rotational position of the rotating body 35, that is, the position of the entering ball portion 43 in which the game ball B has entered, it is possible to easily and reliably determine the rotational position.

When the position discriminating means 61 discriminates the position of the ball entry section 43, the stop control means 62 operates according to the position signal and the hit judging means 63 judges whether or not it is hit.
That is, in the stop control means 62, when a position signal corresponding to each ball entry section 43 is output from the position determination means 61, the variable symbol display means 16
In order to display the position of the ball entry section 43 at that time on the central symbol display section 24, the variable symbol on the central symbol display section 24 is stopped by the position signal. That is, when the ball 3 has entered the ball entry section 43 of "3", the symbol on the symbol display section 24 at the center becomes "3".

At the same time, the random number signal from the random number judging means 57 and the position signal from the position judging means 61 are input to the hit judging means 63, and the hit judging means 63 determines whether or not a hit has occurred. For example, the entering ball part 43 in which the game ball B is contained is "3".
Otherwise, the hit judging means 63 judges that it has come off,
In the case of "3", the hit judging means 63 judges a hit.

When the hit judging means 63 judges that the game ball B has fallen off, the branch claw 52 of the branching means 51 remains in the solid line state in FIG.
Is guided to the branch passage 49, and thereafter, the payout processing of the prize balls is performed by the normal winning processing.

When the hit judging means 63 judges that a hit has occurred, the branch claw 52 of the splitting means 51 switches from the solid line to the virtual line in FIG.
To the branch passage 50. Then, when the detection switch 56 of the branch passage 50 detects the game ball B and confirms a hit, a right state in which the right generation means 64 operates is generated.

When this right state occurs, thereafter, every time one game ball B enters the upper right winning means 13, the right generating means 64 operates, and the opening / closing plate 18a of the big winning means 18 is opened forward for a predetermined time. Therefore, the game ball B falling from above along the game board 5 is guided into the special winning means 18 by the opening / closing plate 18a.
Then, according to the number of the game balls B entering the special winning means 18, the payout processing of the prize balls is performed by the normal prize processing, and the profit is returned to the player.

In this way, the symbols "3" and "3" are displayed on the left and right symbol display sections 22 and 23 of the variable symbol display means 16 by ordinary random number processing, and the central symbol display section is displayed.
In 24, the distribution processing of the game ball B by the distribution means 26,
In other words, since the symbol "3" is displayed by the display processing of the rotation position of the rotating body 35, the symbol "3.3.3" is displayed on each symbol display section 22, 23, 24 of the variable symbol display means 16. Will be done.

Therefore, after the game ball B enters the central winning means 17 and is distributed by the rotating body 35 of the distribution means 26, the game ball B falls from the drop hole 46. In the meantime, the player keeps track of the moving state of
You can play the game while checking it visually.
Moreover, it can be indirectly involved in the symbol change processing of the variable symbol display means 16.

For this reason, the interest of the player is remarkably improved as compared with the case where the symbol of the variable symbol display means 16 is changed by the conventional random number processing, and the game ball B enters the central winning means 17. When the player hits the ball, the player can play the game while watching the game ball B while expecting the destination.
