Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine equipped with a variable winning device that can be changed between a closed state in which pachinko balls are not or not easily received and an open state in which pachinko balls are easily received.

2. Description of the Related Art There is known a pachinko machine in which a movable piece that forms a special winning opening, an attacker, and the like is opened and closed intermittently at a fixed cycle based on the establishment of specific conditions.

Conventionally, when switching the opening and closing of the movable piece, it is common to detect the rise or fall of the monostable multivibrator and to control the operation and non-operation of the driving means for driving the movable piece. However, there is a disadvantage that the opening / closing cycle of the movable piece and the cycle constituting one opening / closing operation are always constant, and the opening / closing operation is monotonous.

Japanese Unexamined Patent Publication No. Hei 2-111383 discloses a timer switch for operating the movable wing of the variable winning device by operating one of three switches provided on the back of the game board. A pachinko machine that changes to a time corresponding to is described. However, in this apparatus, the opening time of the movable wing piece of the variable winning device can be changed by a manual setting operation, and the opening time of the movable wing piece is not changed during the game. The opening / closing cycle in the continuous opening / closing operation of the wing pieces and the cycle constituting one opening / closing operation are always constant.

Japanese Patent Application Laid-Open No. 1-170484 discloses a pachinko machine in which the closing time of the movable member is made shorter in the latter half of the first half and in the latter half of the continuous opening and closing operation of the movable member of the variable winning device so that the closing time of the movable member is different. Machine is listed. In this device, the continuous opening / closing operation of the movable member is clearly divided into a first half and a second half, and in the first half itself and the second half itself of the continuous opening / closing operation, the opening / closing cycle of the movable member and the cycle constituting one opening / closing operation are different. It is always constant.

The specification of the pachinko machine proposed as Japanese Utility Model Publication No. 63-106485 has a point that, in the continuous opening / closing operation of the opening / closing blade, the wait time time to be performed at the beginning of the continuous opening / closing operation is different from the closing time of the opening / closing blade. Although described, the opening / closing cycle of the opening / closing blades during the continuous opening / closing operation and the cycle constituting one opening / closing operation are always constant.

Japanese Unexamined Patent Publication No. 63-222783 describes that the opening time in a single opening / closing operation of the opening / closing blade is different from each opening time in a double opening / closing operation of the opening / closing blade. The opening / closing cycle of the opening / closing wing and the cycle constituting one opening / closing operation are always constant.

SUMMARY OF THE INVENTION An object of the present invention is to make the opening / closing operation irregular by arranging the arrangement of the time from the opening start to the next opening start during the continuous opening / closing operation of the movable piece, thereby providing more amusement. An object of the present invention is to provide a pachinko machine capable of performing high games.

Means for Solving the Problems The pachinko machine of the present invention has a variable winning device that can be changed between a closed state in which pachinko balls are not or not easily received and an open state in which pachinko balls are easily received, and Control means for performing a continuous opening and closing operation to repeat the state and the closed state a plurality of times, the control means,

S008) Then, the above-described defined processes are circulated and executed at predetermined intervals.

FIG. 6 is a flowchart showing the "winning ball detection processing". The CPU 59 that has shifted to the "winning ball detection processing" first reads information temporarily stored in the switch detection unit 62 (step S101). It is determined whether or not the detection signal from the second-type starting port switch 4a is stored, that is, whether or not the ball entering the middle second-type starting port 4 is stored (step
S102) If it is stored, the latch for storing the ball entering the starting opening 4 is reset, 1 is added to the winning number storage counter C (step S103), and 1 is set to the starting opening winning flag F1. (Step S104).

Also, it is determined whether or not the detection signals from the left and right second-type starting ports 5a and 6a are stored, that is, whether or not the incoming balls to the left and right second-type starting ports 5 and 6 are stored. Is determined (step S105), and if it is stored, the latch for storing the balls entering the starting ports 5 and 6 is reset and the winning number storage counter C is reset.
(Step S106), and the starting opening winning memory flag F2
Is set to 1 (step S107).

Next, it is determined whether or not a detection signal from the accessory continuous operation switch 38a is stored, that is, whether or not a ball to the special winning opening 38 in the winning device 3 is stored (step S108). If it is stored, the latch for storing the ball entering the special winning opening 38 is reset and the winning number storage counter C is reset.
, And 1 is added to the continuous operation opening winning number storage counter C1 (step S109).

Also, whether or not the detection signal from the special winning opening winning detection switch 42 is stored, that is, the winning opening 3 in the winning device 3
It is determined whether or not the ball entry to the winning entry 39, 40 is stored (step S110). If the entry is stored, the latch for storing the entry to the winning opening 39, 40 is reset to set the winning number storage counter C. And 1 is added to the special winning opening winning number storage counter C2 (step S111).

In this embodiment, as long as the large winning opening solenoid SOL1 is magnetized by the “solenoid driving process” described later to open the blades 2, 2, the blades 2, 2 of the winning device 3 are closed. The special prize port 38 and the prize ports 39 and 40 in the prize device 3 are not won.

Next, it is determined whether or not a detection signal from a winning detection switch provided in another winning opening is stored, that is, to the left and right tulip-type characters 7, 8 and the left and right winning openings 10, 11, and the like. It is determined whether or not the winning ball is stored (step S112). If it is stored, the latches corresponding to these winning ports are reset, 1 is added to the winning number storage counter C, and the processing of this cycle is performed. Is completed (step S113), and the flow shifts to "prize ball payout processing".

As described above, the "winning ball detection process" is executed in a cycle at predetermined intervals, and the value of each counter is sequentially incremented each time a ball is detected in each of various winning ports. It will be.

FIG. 7 is a flowchart showing the “prize ball payout process”. The CPU 59 that has shifted to the “prize ball payout process” first determines whether or not the payout process continuation flag F3 is set,
It is determined whether or not the prize ball payout device (not shown) is operating (step S201). If the prize ball payout device is not currently operating, the value of the winning number storage counter C is set to 0. Is determined (step S202), and if any value is stored in the winning number storage counter C, the prize ball payout device (not shown) is driven to determine the number corresponding to one winning. Start paying out pachinko balls (step S20
3), the payout processing continuation flag F3 is set to 1 to store that the operation of the prize ball payout apparatus has been started, and the processing of this cycle is ended (step S204);
Move to

On the other hand, if it is determined in step S201 that the payout process continuation flag F3 has been set, the switch detection unit
Whether or not the operation completion signal of the prize ball payout device (not shown) is stored in 62, that is, “prize ball payout processing” before the previous cycle.
It is determined whether or not one operation of the prize ball dispensing device operated in (2) is completed (step S205). If the operation of the prize ball dispensing device is completed, the number of pachinko balls corresponding to one winning is obtained. Since the payout has been completed, 1 is subtracted from the value of the winning number storage counter C (step S206), the payout processing continuation flag F3 is reset (step S207), and the flow shifts to "solenoid drive processing".

If the operation of the prize ball payout device has not been completed in step S205, a new payout cannot be started, so that the process in the cycle is ended and the process proceeds to the “solenoid drive process”.

Thereafter, each time the “prize ball payout process” is executed, the same process as described above is repeated, and the prize ball payout device operates sequentially until the value of the winning number storage counter C becomes 0.

FIGS. 2 (a) and 2 (b) are flowcharts showing the "solenoid driving process". The CPU 59 that has shifted to the "solenoid driving process" firstly sets the blades 2, 2 of the winning device 3.
It is determined whether or not the continuous opening flag F6 indicating that the blades are being continuously opened and closed is set (step S301).
If it is not during the continuous opening and closing of 2, the big win opening flag F
Whether or not 4 is set, that is, the type 2 opening 4, 5, 6
It is determined whether or not the blades 2, 2 are in an opened state due to the winning in (step S302).

Then, if the special winning opening release flag F4 is not set, it is determined whether or not the starting opening winning storage flags F1 and F2 are set, that is, the pachinko ball is placed in one of the second-type starting openings 4, 5, and 6. It is determined whether or not the player has entered a ball (steps S303 and S304). If the starting port winning memory flags F1 and F2 have not been set, the continuous operating port winning number memory for storing the ball in the special winning port 38 is stored. It is determined whether or not the value of the counter C1 is 0 (step S305), and the continuous operation opening winning number storage counter is determined.
If the value of C1 is 0, after these discrimination processes are completed, the "solenoid driving process" in the cycle is terminated, and the process returns to the "winning ball detection process" again.
Steps for "prize ball payout processing" and "solenoid drive processing"
The determination process from S301 to step S305 is executed at predetermined intervals.

When the pachinko ball wins in the middle type 2 starting port 4 while the CPU 59 repeats the processing in this way, the middle type 2 starting port switch 4a detects the pachinko ball entering and the switch detecting unit 62
Are set. After reading the information of the switch detection unit 62 in step S101 of the "winning ball detection process", the CPU 59 confirms that the ball has entered the middle type 2 starting port 4 (switch S102), and sets the starting port winning memory flag F1. Is set (step S104).

Step S3 in the "solenoid drive process" of the same cycle
The CPU 59, which has confirmed that the starting port winning memory flag F1 is set in 03, excites the big winning port opening solenoid SOL1 to open the blades 2, 2, while the character solenoid S
OL2 is magnetically excited to bring the movable member 31 into contact with the upper surface of the guide plate 30, and the ball path changing piece 43 is projected from the inner wall 35 (step S306), and the timer T is started to start timekeeping. The winning storage flag F1 is reset, and the special winning opening opening flag F4 is set (step S307).

Next, the elapsed time measured by the timer T is the third time.
Set time (t) as shown in the timing chart of FIG.
It is determined whether or not c, tb, and ta have been reached (steps S308, S309, and S310). At the present time immediately after the start of the timer T, the elapsed time T measured by the timer T is also equal to the set time ta. Since this is not the case, the “solenoid driving process” of this cycle ends after the determination processes in steps S308, S309, and S310 are completed.

In the “solenoid drive processing” in the next cycle and thereafter, since the special winning opening opening flag F4 has already been set, step S3
01, after performing the determination processing of step S302, step S308
Then, in the same manner as described above, only the determination processing of steps S308, S309, and S310 is executed.

In this manner, when it is determined that the elapsed time T measured by the timer T has reached the set time ta while the “solenoid driving process” is repeatedly executed at predetermined intervals (step S310), the CPU 59 Releases the magnetic excitation of the large winning opening opening solenoid SOL1 and closes the blades 2 and 2 (step S31).
1) It is determined whether or not the special winning opening flag F5 is set (step S312), but since the special winning opening flag F5 is not set at present, after the determination process of step S312 is completed, the cycle is determined. Is completed.

In the “solenoid driving process” executed in the next cycle and thereafter, when it is determined that the elapsed time T measured by the timer T has reached the set time tb (step S309), C is determined.
PU59 excites the big win opening solenoid SOL1 again
2 and 2 are released (step S313). Further, when it is determined that the elapsed time T measured by the timer T has reached the set time tc (step S308), the CPU 59 controls the magnetism of the special winning opening opening solenoid SOL1. While the excitation is released and the blades 2 and 2 are closed, the magnetic excitation of the character solenoid SOL2 is released and the movable member 31 is retracted from the upper surface of the guide plate 30 and the spherical path changing piece 43 is retracted from the inner wall 35 (step S314). ),
The timer T and the special winning opening opening flag F4 are reset (step S315), and the “solenoid driving process” of the cycle ends.

On the other hand, when a pachinko ball wins in either of the left and right type 2 starting ports 5 and 6, the left and right type 2 starting port switches 5a and 5b detect the pachinko ball entering. The corresponding latch of the switch detection unit 62 is set, and in step S105 of the "winning ball detection process", the ball is confirmed to have entered the left and right type 2 starting openings 5 and 6, and the starting opening winning memory flag F2 is set by the CPU 59. It is set (step S107).

Step S3 in the "solenoid drive process" of the same cycle
After confirming that the starting port winning memory flag F2 is set in 04, the CPU 59 magnetizes the large winning port opening solenoid SOL1 to open the blades 2 and 2 (step S316), starts the timer T, and counts the time. On the other hand, the starting opening winning memory flag F2 is reset, the winning opening opening flag F4 and the winning opening opening flag F5 are set (step S317), and the “solenoid driving process” of this cycle ends.

In the “solenoid drive processing” in the next cycle and thereafter, since the special winning opening opening flag F4 has already been set, step S3
01, after performing the determination processing of step S302, step S308
Then, it is determined whether or not the elapsed time measured by the timer T has reached the set time tc, tb, ta (step S).
308, step S309, step S310) At the present time immediately after the start of the timer T, the elapsed time T measured by the timer T is less than the set time ta.
After the end of the determination processing in step 308, step S309, and step S310, the "solenoid driving processing" of this cycle ends.

In the "solenoid driving process" executed in the next cycle and thereafter, if it is determined that the elapsed time T measured by the timer T has reached the set time ta (step S310), C is determined.
PU59 releases the magnetic excitation of the special winning opening opening solenoid SOL1, closes the blades 2 and 2 (step S311), and sets the special winning opening opening flag F5.
Is set (step S31).
2). In this case, the large winning opening opening flag F5 has already been set based on the winning in the left and right type 2 starting openings 5 and 6,
After completion of the determination processing in step S312, the process proceeds to step S318,
Reset the timer T and the winning opening flag F4, F5,
The “solenoid driving process” of this cycle ends.

That is, in the present embodiment, when the pachinko ball wins in the middle type 2 starting port 4, the large winning port opening solenoid SOL1 is magnetized only for the set time ta (= E), and the blades 2, 2
Are opened for a set time tb-ta, and further opened for a set time tc-tb (= E), and the character solenoid SOL2 is always magnetized during this time. Then, while the set time tc has elapsed, the movable member 31 is in contact with the upper surface of the guide plate 30 and the spherical path changing piece 43 projects from the inner wall 35 (see the timing chart of FIG. 3). When a pachinko ball wins in the left and right type 2 starting ports 5 and 6, the large winning port opening solenoid SOL1 is magnetized only for the set time ta (= E) and the blades 2, 2
Only open.

When the blades 2 and 2 are released in this manner, it becomes possible to enter the prize device 3. When pachinko balls enter the prize device 3, these pachinko balls are finally won. Various prize ports arranged in the space 26, that is, special prize ports 38 or prize ports 39 and 40, will be won, and the detection switches provided in these prize ports will detect switches according to the winning state. When the latch of the unit 62 is set, the winning information stored in the switch detecting unit 62 is confirmed by the CPU 59 in the above-mentioned "winning ball detection process".

Briefly describing the flow of the pachinko balls that have entered the prize device 3, the pachinko balls that have entered the prize device 3 first enter the prize space 26 and fall on the guide plate 30. If the character solenoid SOL2 is in a magnetized state, a movable member with a wedge shape in horizontal cross section
The pachinko ball rolling on the guide plate 30 is distributed in the left and right direction by hitting the wedge-shaped tip of the movable member 31 because the 31 is in contact with the upper surface of the guide plate 30, and falls from the trailing edge of the guide plate 30. However, there is a high probability of entering the rear lower space 26b partitioned by the partition wall 36. When the character solenoid SOL2 is magnetized, the ball path changing piece 43 protrudes inward from the inner wall 35, so that the pachinko ball entering the lower space 26b on the rear side includes the inner wall 35, the partition wall 36, and the rotating drum. It will be temporarily stored in the space surrounded by the 32 peripheral walls 32c.

Since the rotation of the rotating drum 32 has already started at the same time as the power is turned on, the inner wall 35, the partition 36 and the peripheral wall 32c of the rotating drum 32
The pachinko balls stored in the space surrounded by are taken into the inside of the rotary drum 2 via the notches 32b, 32b in a state where the notches 32b, 32b in the peripheral wall 32c face in the left-right direction, The rotating drum 32 is rotatably supported by a rotating shaft 33, and
The fin 34a of the rotating body 34 that rotates together with the rotating drum 32 due to the friction existing between the rotating shaft 33 and the rotating shaft 33,
The phase of the rotational position of the rotator 34 with respect to is changed.

When the rotating drum 32 further rotates and one of the notches 32b, 32b reaches near the bottom dead center, the pachinko ball in the rotating drum 32 is discharged onto the bottom surface 41 via the one notch 32b. Then, it rolls toward the front on the guide plate 37 in the space on the near side partitioned by the partition wall 36, and finally wins either the special winning opening 38 or the winning opening 39, 39.

Further, before the pachinko balls temporarily stored in the space surrounded by the inner wall 35, the partition wall 36, and the peripheral wall 32c of the rotary drum 32 are taken into the rotary drum 32, the character solenoid SO is inserted.
When the magnetic excitation of L2 is released and the ball path changing piece 43 retreats from the inner wall 35, the pachinko ball whose lower part is supported by the ball path changing piece 43 falls as it is, and is rearwardly separated by the partition wall 36. The winning opening 40 provided at the lower left and right ends of the lower space 26b on the side is won.

On the other hand, if the character solenoid SOL2 is in a non-excited state when the pachinko ball enters the winning space 26, the movable member 31 is retracted above the guide plate 30, and the pachinko ball receives the interference of the movable member 31. Induction plate 30 without
After rolling on the upper side, it falls from the rear edge of the guide plate 30 and enters the rear lower space 26b partitioned by the partition wall 36.

The pachinko ball that has fallen from the approximate center of the rear edge of the guide plate 30 falls on the outer peripheral surface of the peripheral wall 32c if the cutouts 32b and 32b in the peripheral wall 32c of the rotating drum 32 are in the left-right direction. The pachinko balls are distributed in the left and right directions, and usually win the prize holes 40 provided at the lower left and right ends of the lower space 26b on the rear side partitioned by the partition 36, but the distributed direction of the pachinko balls is the rotation of the rotating drum 32. If the direction is opposite,
During the time lag when the pachinko ball falling and rebounding on the outer peripheral surface of the peripheral wall 32c falls again, one of the notches 32b of the peripheral wall 32c rotates to the top dead center side, and the notch 32b
The pachinko ball may be taken into the rotating drum 32 via the.

In this case, the pachinko balls taken into the rotating drum 32 are fins 34a of the rotating body 34 that rotates together with the rotating drum 32.
After changing the phase of the rotational position of the rotating body 34 with respect to the rotating shaft 33, the liquid is discharged onto the bottom surface 41 through the other notch 32b, and the guiding plate of the space on the near side partitioned by the partition 36. 37, it rolls toward the front, and finally wins either the special winning opening 38 or the winning opening 39, 39.
In addition, the pachinko balls that have fallen from the left and right ends of the rear edge of the guide plate 30 fall in the vertical direction as they are, and win the winning holes 40 provided at the lower left and right lower ends of the rear lower space 26 b partitioned by the partition 36. Will do.

When the pachinko ball enters the special winning opening 38, the accessory continuous operation switch 38a detects the entry of the pachinko ball, sets the corresponding latch of the switch detection unit 62, and sets the CPU 5
9 reads the information of the switch detecting unit 62 in the switch S101 of the "winning ball detection process", confirms the ball entering the special winning opening 38 (step S108), and stores 1 in the continuous operating opening winning number storage counter C1. Is added, the number of winnings in the special winning opening 38 is stored (step S109).

Step S3 in the "solenoid drive process" of the same cycle
In step 05, the CPU 59 confirms that the numerical value is stored in the continuous operation opening winning number storage counter C1 and starts the timer T to start timekeeping, and the special winning opening opening solenoid SO
The solenoid switching signal S for storing the switching operation of L1, the set time selection index i, and the continuous opening flag F6 are each set to 1 (step S319).
L1, character solenoid SOL2, drive processing of the large winning opening opening solenoid SOL1 etc., which drives the blades 2, 2 which are movable pieces, based on the set values of the ROM 60 which stores the drive continuation time and drive suspension time of the motor M, etc. Will start.

The CPU 59 first reads the i-th switching time ti from the ROM 60 storing the timing chart of the switching time ti (see FIG. 1), stores it in the switching time storage register R (t) (switch S320), and sets the timer T The elapsed time T measured by the above is the value of the switching time storage register R (t), that is,
It is determined whether the i-th switching time ti has been reached (step S321). If the elapsed time T measured by the timer T has not reached the i-th switching time ti, then the process proceeds to step S322. The process proceeds to determine whether or not the value of the special winning opening winning number storage counter C2 is 3, that is, whether or not three pachinko balls are winning in the winning device 3.

If the value of the special winning opening winning number storage counter C2 is 3, the character solenoid SOL2 is magnetically excited to bring the movable member 31 into contact with the upper surface of the guide plate 30 and to cause the ball path changing piece 43 to protrude from the inner wall 35. (Step S323) If the value of the special winning opening winning number storage counter C2 is other than 3, the process proceeds to step S324 without executing the process of step S323.

Next, it is determined whether or not the value of the special winning opening winning number storage counter C2 is 7, that is, whether or not seven pachinko balls are winning in the winning device 3 (step S324). If the value of the number storage counter C2 is 7, when the value of the counter C2 becomes 3 is detected, the magnetic excitation of the magnetized character solenoid SOL2 is released, and the movable member 31 is moved to the induction plate 30. Evacuate upward and change ball path 43
Is retracted from the inner wall 35 and the driving of the motor M is stopped to stop the driving of the rotating drum 32 and the rotating body 34 (step S325).

In this case, by confirming the input of the home position detection signal from the rotary body home position detection switch 57, the notched portions 32b, 32b of the rotary drum 32 are turned up and down as shown in FIG. Since the driving of the rotating drum 32 is stopped, the probability that the pachinko ball once taken into the rotating drum 32 will win the special winning opening 38 increases.

If the value of the special winning opening winning number storage counter C2 is other than 7, the process proceeds to step S326 without executing the process of step S325.

Next, it is determined whether or not the value of the special winning opening winning number storage counter C2 is 10 or more, that is, whether or not ten or more pachinko balls are winning in the winning device 3 (step S326). If the value of the win winning number storage counter C2 is 10 or more, the magnetizing solenoid of the special winning opening opening solenoid SOL1 is released and the blades 2 and 2 are closed (when SOL1 is magnetized), and the character drive solenoid is operated. Release the magnetic excitation of SOL2 and move the movable member 31
Is retracted above the induction plate 30 (when SOL2 is magnetized) (step S327), and the motor M stopped when the value of the special winning opening winning number storage counter C2 is detected to be 7 Of the rotating drum 32 and the rotating body 34
Is restarted (step S328), 1 is subtracted from the value of the continuous operation port winning number storage counter C1, and the fact that one continuous opening operation based on winning in the special winning port 38 is stored, and
The special winning opening winning number storage counters C2 and C1 store the number of pachinko balls that have won the winning device 3 during the continuous opening operation.
Continuous release flag F6 that stores that the continuous release operation is being performed
Is reset (step S329), the timer T is reset (step S330), the operation state of the pachinko machine is returned to the initial state, and the "solenoid driving process" of this cycle is ended.

Since the value of the continuous operation opening winning number storage counter C1 is not reset, the continuous opening operation of the blades 2 and 2 is repeatedly performed each time the value of the counter C1 is confirmed in step 305 of the "solenoid driving process". That is, in the present embodiment, the number of repetitions of the continuous opening operation based on the pachinko ball that has entered the special winning opening 38 during one continuous opening operation is limited to 10 times.

Further, if it is determined in step S326 that the value of the special winning opening winning number storage counter C2 is less than 10, the processing from step S327 to step S330 is not executed, and after the determination processing in step S326 is completed, The “solenoid drive processing” of the cycle ends.

On the other hand, if it is determined in step S321 that the elapsed time T measured by the timer T has reached the i-th switching time ti, then the solenoid switching signal S
Is determined whether the value is 1 or -1 (step S3
31).

If the value of the solenoid switching signal S is 1, as shown in FIG. 1, i = 1, 3, 5,..., That is, the large winning opening opening solenoid SOL1 is magnetized to open the blades 2, 2. Since it is time to go to step S332, the big win opening solenoid SOL1 is magnetically excited to open the blades 2, 2, while if the value of the solenoid switching signal S is -1, this is shown in FIG. , I.e., i = 2, 4, 6,..., That is, it is time to release the magnetic excitation of the large winning port opening solenoid SOL1 and close the blades 2, 2, so that the process proceeds to step S333 to enter the large winning port. The magnetic excitation of the open solenoid SOL1 is released, and the blades 2, 2 are closed.

For example, if the value of the set time selection index i is 1, the value of the solenoid switching signal S is 1, and in step S321, the elapsed time T measured by the timer T reaches the first switching time t1. At the time of determination,
Based on the value of the solenoid switching signal S (= 1),
The first release of No. 2 will be executed (see FIG. 1).

Next, it is determined whether or not the value of the set time selection index i is 10, that is, whether or not this processing cycle is a cycle for executing the fifth closing of the blades 2, 2 (step S334). If the value of the set time selection index i is 10, the character drive solenoid SOL2 is magnetized, and the fifth closing of the blades 2, 2 causes the movable member 31 to abut on the upper surface of the guide plate 30; While the path changing piece 43 is projected to the inner wall 35 (step S335), if the value of the set time selection index i is other than 10, the processing of step S335 is not executed and step S336 is not executed.
Move to

Next, whether or not the value of the set time selection index i is 29,
That is, it is determined whether or not this processing cycle is a cycle for performing the fifteenth opening of the blades 2 and 2 (step S336).
If the value of the set time selection index i is 29, the fifth
The excitation of the character drive solenoid SOL2, which was excited with the closing of the first time, is released, and the movable member 31 is retracted from the upper surface of the guide plate 30 with the 15th opening of the blades 2, 2,
Further, the spherical path changing piece 43 is retracted from the inner wall 35, and the driving of the motor M is stopped to stop the driving of the rotating drum 32 and the rotating body 34 (step S341).

If the value of the set time selection index i is other than 29, the process proceeds to step S337 without executing the process of step S341. Next, it is determined whether or not the value of the set time selection index i is 36, that is, whether or not this processing cycle is the cycle for executing the eighteenth closing of the blades 2, 2 (step
S337) If the value of the set time selection index i is not 36, the flow shifts to step S338.

Next, the value of the set time selection index i is updated by adding 1 (step S338). Based on the value of the index i, the i-th switching time ti is read from the ROM 60 and stored in the switching time storage register R (t). It is stored (step S339), the sign of the solenoid switching signal S is inverted (step S340), and the “solenoid driving process” of this cycle ends.

Therefore, the sign of the solenoid switching signal S is sequentially inverted each time the elapsed time T measured by the timer T reaches the switching time ti stored in the ROM 60 and the switching of the big win opening solenoid SOL1 is executed. Then, the special winning opening solenoid SOL1 is driven based on the timing chart (see FIG. 1) stored in the ROM 60, and the continuous opening operation of the blades 2, 2 is executed.

If it is determined in step S337 that the value of the set time selection index i is 36, it is determined that the eighteenth closing of the blades 2, 2 has already been performed in the "solenoid driving process" of this cycle. This means that all the continuous opening operations of the blades 2 and 2 in the present embodiment are completed, so the process proceeds to step S328 and the blades 2 and 2
The drive of the motor M stopped with the 15th opening of 2 is restarted, the rotation drive of the rotating drum 32 and the rotating body 34 is restarted, and 1 is subtracted from the value of the continuous operation opening winning number storage counter C1. The special winning opening 38 stores the completion of one continuous opening operation based on the winning, and stores the number of pachinko balls that have won the winning device 3 during the continuous opening operation. The continuous release flag F6 storing that one continuous release operation is being performed is reset (step S329), the timer T is reset (step S330), and the operation state of the pachinko machine is returned to the initial state. Solenoid drive processing "ends.

As described above, the special winning opening solenoid SOL1 that drives the movable blades 2, 2 is driven based on the set time ti set in the ROM 60, as shown in the timing chart of FIG. Although controlled, in the present embodiment, the drive continuation time, that is, the incremental amount of the opening time of the blades 2, 2 is set to the time A, while the drive suspension time,
That is, the incremental amounts of the blades 2, 2 during the closing time are A, B,
By setting C and D to four types, the operation of the blades 2 and 2 is diversified. In the case of this embodiment, the opening time and closing time of the blades 2, 2 are determined by the set time ti and Ti (i = i + 1).
It is a matter of course that the opening time and the closing time of the blades 2, 2 can be arbitrarily set by changing the set time ti.

For example, as in the present embodiment, only the closing time may be changed while keeping the opening time of the blades 2 and 2 constant, or only the opening time may be changed while the closing time of the blades 2 and 2 is fixed or the closing time may be changed. Both the time and the opening time may be changed.

In this embodiment, the character solenoid SOL2 for driving the movable member 31 and the ball path variation piece 43 and the motor M for driving the rotating drum 32 and the rotating body 34 are also basically RO
Since the drive is controlled based on the set time ti set in M60, the operations of the movable member 31, the spherical path varying piece 43, the rotating drum 32, and the rotating body 34 are also set, for example, in steps S334 and S336. By changing the comparison value for the selection index i, the control can be appropriately performed.

The timing chart shown in FIG. 1 shows the basic operation states of the special winning opening opening solenoid SOL1, the character solenoid SOL2, and the motor M. In particular, regarding the character solenoid SOL2 and the motor M, FIG. The switching of the operation is not always performed at the timing shown in FIG. That is, if three pachinko balls are awarded in the winning device 3 earlier than the fifth closing of the blades 2, 2 is performed after the continuous opening operation of the blades 2, 2 is started, The character solenoid SOL2 is magnetized without waiting for the fifth closing of the blades 2, 2 (step S323), and a prize is won earlier than the 15th opening of the blades 2, 2 is executed. When seven pachinko balls are won in the device 3, the magnetic excitation of the character solenoid SOL2 is released without waiting for the fifteenth opening of the blades 2, 2, and the driving of the motor M is stopped ( Step S32
Five).

In addition, if ten or more pachinko balls are awarded in the prize winning device 3 earlier than the eighteenth closing of the blades 2, 2, the waiting for the eighteenth closing of the blades 2, 2 must be performed. No one
The continuous opening operation is completed (steps S327 to S327).
Step S330) In the present embodiment, in addition to the time control of the character solenoid SOL2 and the motor M, the control based on the number of winnings in the winning device 3 is used in combination with the movable piece 31, the ball path variation piece 43. , Rotating drum 32, rotating body 34
And so on.

According to the pachinko machine of the present invention, during the continuous opening / closing operation in which the open state in which pachinko balls are easily accepted and the closed state in which pachinko balls are not accepted or difficult to accept are repeated a plurality of times, from the opening start to the next opening start The opening / closing operation is made irregular by making the time arrangement irregular, so that the opening / closing operation is not repeatedly performed at a constant cycle, so that it does not become monotonous, and a more entertaining pachinko game is performed. be able to.
