2. Description of the Related Art As a typical ball-and-ball game machine, a pachinko-game machine that repels a pachinko ball to play a game has become widespread and has become popular with players. By the way, in recent years, pachinko game machines, when a certain specific game state is reached, a large variable prize ball device provided on the game board opens until a relatively large amount of prize balls are produced, and many prize balls are released in a short time. The things that can be acquired are the mainstream. An example of such a pachinko gaming machine is a pachinko gaming machine generally called a "fever" (registered trademark owned by the applicant) type. Such a pachinko gaming machine is provided with a variable display device on its gaming board. This variable display device
When the ball hits the starting winning opening provided on the game board, the variable display is started, and the variable display is stopped by the operation of the push button switch by the player for a certain period of time.
When the combination of the display modes of the variable display device at the time of stop coincides with a predetermined combination (generally, when three drums or a digital display indicates "7"), a variable having a large winning area is provided. The winning ball device opens for the advantage of the player, and the open state continues for a predetermined time or until a predetermined number of prizes are won.
As long as there is a ball hitting the winning opening repeatedly in the open state, the open state is repeated a predetermined number of times. Therefore, the player is given the chance to obtain a large amount of prize balls in a short time by changing the variable winning ball device to the open state.

[0003]

By the way, in order to obtain the above-mentioned chance, as a premise, the variable display device must display a predetermined display state, a so-called specific display state. In the "fever" type pachinko gaming machine, the probability that the specific display state appears was limited to a certain value (generally, a probability of 1/200 or less). Therefore, when the specific display state appears once, it takes time until the next specific display state is reached, and it is not possible to sufficiently attract the player's interest. The present invention has been made in view of the above circumstances, and an object thereof is to provide a ball game machine in which the appearance interval of the specific display state is not always constant but changes under a certain condition. To do.

[0004]

In order to achieve the above-mentioned object, in the present invention, a variable display device, which is arranged on a game board and is capable of variably displaying in a plurality of display states, is beneficial to a player. A predetermined value giving means for giving a predetermined value, a variable display start signal generating means for generating a signal for variably starting the display mode of the variable display device, and a signal for instructing the variable display of the variable display device to stop. In response to the stop command signal generating means and the output of the variable display start signal generating means, the variable display device is variably driven, and the variable display driving of the variable display device is stopped in accordance with the output of the stop command signal generating means. A ball game machine including display drive control means and specific display state determination means for determining that the variable display device can be in a specific display state in which the predetermined value providing means can be operated. The ball game machine further includes a specific display state probability increase control means for increasing the appearance probability of the variable display device displaying the specific display state after the output based on the output of the specific display state determination means. A specific display state probability return control means for stopping the operation of the specific display state probability increase control means and returning to the original probability state when the number of times the specific display state after the increase reaches a predetermined number; , And the predetermined number of times is not updated by the output of the specific display state determination means output after the appearance probability increases until the predetermined number of times is reached.

[0005]

According to the present invention, when the first specific display state appears, the predetermined value adding means is activated and the probability that the next specific display state appears will be higher than the first appearance probability. Since it is possible to perform such a high probability state until the specific display state appears a predetermined number of times, the appearance interval of the specific display state is not constant, and
More entertaining games can be provided. Further, the predetermined number of times that the high-probability state is continued is not updated during the continuation of the high-probability state, so that the specific display state does not appear more than continuously.

In FIG. 7B, only one drum-shaped variable display member 71 is shown, but the other drum-shaped variable display members 72 and 73 are also drilled in exactly the same manner, and the description thereof is omitted. To do. 20 through holes 94
Correspond to the light receivers A to E.
It is classified into 94e. Further, the 20 through holes 94 are
Two through holes 94 of different types are arranged in each fan-shaped zone (ten of which are formed) formed by connecting the tooth tips of the ratchet gears 89 to 91 to the center of rotation. Has been drilled. According to the illustrated embodiment,
Through holes 94a and 94d are formed in the zone for detecting the symbol 1 (hereinafter referred to as the "1" zone).
When the zone is stopped at the position corresponding to the light receivers 101a to 101e, the symbol displayed to the player is 1. At this time, the position of the "1" zone and the display position of the symbol "1" drawn on the surface of the drum-shaped variable display device 71 are in a positional relationship shifted by 180 degrees. In the same manner, through holes 94a, 94e, and
Through holes 94b and 94c in the "3" zone, through holes 94b and 94d in the "4" zone, and through holes 9b in the "5" zone.

b, through holes 94c and 94d in the "7" zone, through holes 94c and 94e in the "8" zone, and 9 in the "9" zone.
In the zones 4a, 94c, and "0", 94d, 94e are provided, respectively. Therefore, as shown in FIGS. 8A to 12B, when the symbol displayed on the drum-shaped variable display member 71 is “1”, “1” is displayed.
The zones are located at positions corresponding to the light receivers 101a to 101e, and the light emitted by the light projectors 100a to 100e can pass through only the through holes 94a and 94d. Similarly, when the symbol is "2",
The "2" zone is located at a position corresponding to the light receivers 101a to 101e, and the light can pass through the through hole 9
4a and 94e only, and when the symbol is "3", the "3" zone is located at a position corresponding to the light receivers 101a to 101e, and light can pass through the through holes 94b and 94c. When the pattern is "4", the "4" zone is located at a position corresponding to the light receivers 101a to 101e, and light can pass through.
When only the through holes 94b and 94d are provided and the design is "5", the "5" zone is located at a position corresponding to the light receivers 101a to 101e, and light can pass through the through holes 94b. , 94e only, and when the design is "6", the "6" zone is the light receivers 101a to 101e.
The light can pass through only the through holes 94a and 94b, and when the design is "7", the "7" zone indicates the light receivers 101a to 101.
Since it comes to the position corresponding to e, light can pass only through holes 94c and 94d, and the design is "8".
, The “8” zone is the light receivers 101a to 10a.
Since it is in the position corresponding to 1e, light can pass through only the through holes 94c and 94e. When the design is "9", the "9" zone is the light receiver 101a.
Therefore, the light can pass through only the through holes 94a and 94c, and when the symbol is "0", the "0" zone is the light receiver 101.
It comes to the positions corresponding to a to 101e, and light can pass through only the through holes 94d and 94e.

As described above, since the through holes 94 are formed in the three drum-shaped variable display members 71 to 73 in exactly the same state, the light receivers 101a to 101a.
To activate any two of 1e at the same time, 3
It is necessary that the symbols drawn on the surfaces of the one drum-shaped variable display members 71 to 73 are the same symbols (numerals), and at that time, the signals detected by the light receivers 101a to 101e are control described later. Sent to the circuit. Light receiver 101a
The signals sent from the ˜101e are identified in the control circuit as a 5-bit signal as shown in FIG. In this figure, “1” indicates a state of receiving light, and “0” indicates a state of not receiving light.

The variable display device 70 configured as described above.
In the normal specific display state, the display of the drum-shaped variable display members 71 to 73 is “5, 5, 5” “7,
Three combinations of "7, 7" and "9, 9, 9" are selected. The appearance probability of this combination is calculated as follows. First, each drum has one "5",
The probability of displaying “5” on one drum is “1/10”
It becomes one by one. Therefore, the probability that "5" is displayed on the three drums is "1/1000" obtained by multiplying each probability. Similarly, the probability that "7" is displayed on the three drums is "1/1000", and the probability that "9" is displayed on the three drums is "1/1000". And
The probability of adding these three probabilities is "3/1000",
The appearance probability of the specific display state at the normal time on the variable display device 70 (hereinafter, sometimes referred to as normal probability).

By the way, the control circuit described later works to increase the appearance probability of the next specific display state when the first specific display state appears with the above-mentioned probability of "3/1000". Specifically, when the normal probability is “5, 5,
In the case of the three combinations of "5", "7,7,7", "9,9,9", the specific display state is set. "0""1,
"1,1" and "3,3,3" are also determined to be in the specific display state. Therefore, when the appearance probability increase control means operates, the appearance probability of the specific display state (hereinafter, sometimes referred to as high probability) is “6/1000”. Then, in the case of this embodiment, the above-mentioned increased probability of 2
When the times specific display state appears, the operation of the appearance probability increase control means ends, and the normal appearance probability is restored. At this time, the normal probability that the first specific display state has appeared (“3/1000” → one occurrence every 333 times) and the two high probabilities (“6
/ 1000 ”→ appears once in 166.5 times) and the average probability (“ 3/666 ”→ appears once in 222 times) is a constant appearance probability that is generally set in the past. / 20
It does not exceed the value of "0". Also, when the specific display state is reached while the appearance probability increase control means is operating,
The high probability state is not newly updated twice from that time, but only twice from the first operation of the appearance probability increase control means, and the value is not updated. This prevents the high probability state from continuing semipermanently. In addition, the probability display in each state is provided on the game board 7 of the pachinko gaming machine 1, the probability display 10
5 is displayed to inform the player.
The probability indicator 105 does not necessarily have to display a numerical value.

The control of the above-described embodiment will be described with reference to FIG. FIG. 13 is a block diagram of the control circuit configuration. In the figure, the control circuit includes a microcomputer 120 as a control center.

Reference numeral 30 decodes the address data from the MPU 121 and gives a chip select signal to each of the ROM 122, RAM 123, input circuit 124, output circuit 125, and sound generator 126. In this example,
The ROM 122 is a programmable ROM so that the contents can be rewritten, that is, the program data for the MPU 121 stored therein can be changed when the need arises. Then, the MPU 121 gives a control signal to the variable display device 70, the variable winning ball device 50 and the like in accordance with the program data stored in the ROM 122 and in response to the input of each control signal described below.

The following signals are given to the microcomputer 120 as input signals.

The detection signals detected by the light receivers 101a to 101e are given to the light receiver circuit 135 and given to the microcomputer 120 as a combination determination signal of the drum-shaped variable display members 71 to 73.

The microcomputer 120 also supplies control signals to the following circuits and devices. First, a drum drive signal is applied to the drum solenoids 95a to 95c of the drum-shaped variable display members 71 to 73 via the solenoid circuit 136. The projectors 100a to 10a through the projector circuit 137.
A lighting signal is given to 0e. A drive signal is given to the drum motor 82 of the drum-shaped variable display members 71 to 73 via the motor circuit 138. A drive signal is given to the solenoid 66 via the solenoid circuit 139 to open / close the opening / closing plate 54.

A control signal for displaying is given. Furthermore, amplifier 1
The sound effect is notified from the speaker 18 via 43.
A predetermined DC voltage is supplied from the power supply circuit 144 to each circuit having the above configuration.

14 to 16 are flow charts showing the operation of the control circuit shown in FIG. Here, the specific operation of this embodiment will be described with reference to FIGS. First, when the power supply of the control circuit is turned on, the microcomputer 120 initializes the stored contents of the LED circuit 141 (step S1) and waits for the next signal. By the way, when the process of step S1 is completed, the microcomputer 120 is processed so that the interrupt routine shown in FIG. 15 is always interrupted. This interrupt routine is performed by a pulse frequency dividing circuit (interrupt pulse generating circuit) 12
The processing of steps S52 to S56 is performed based on the signal interrupted every 9 to 4 mS. That is, it is determined whether or not the pachinko ball in the game has won in any of the start winning openings 52, 11a, 11b.
The determination is made based on the detection signals of 3, 34a, 34b (step S52), and one of the start winning openings 52, 11a, 1
If the player has won 1b, the variable display device 70
Is displayed during variable display (step S53).
When the variable display is being performed, the fact that the winning prize has been started is notified from the speaker 18 via the amplifier 143 (step S54). Further, after the notification, or when the variable display device 70 is not performing the variable display, the RAM 12
It is determined whether or not the value of the starting winning prize memory counter stored in 3 is "4" (step S55), and when it is not "4", 1 is added to the numerical value stored in the starting winning prize memory counter. Together with LED circuit 141 via L
The EDs 77a to 77d are turned on (step S56), and the interruption ends. On the other hand, if there is no detection signal from the start prize detection switches 33, 34a, 34b in step S52, or if the numerical value stored in the start prize storage counter is "4" in step S55, the interruption ends. From step S52 to step S56,
It is always interrupted by the microcomputer 120.

On the other hand, returning to the main routine and explaining, the game is started in the pachinko gaming machine 1 after being initialized in step S1, and the game area 9 of the game board 7 is started.
A pachinko ball is driven into the game, and the driven pachinko ball is processed by the interrupt routine, whereby it is determined whether or not the value of the starting winning prize memory counter is "0" (step S2). When the value of the starting winning prize memory counter is "0", this determination is repeated. When the value of the starting winning prize memory counter is not "0", the microcomputer 120 first subtracts 1 from the starting winning prize memory counter, and correspondingly turns off one of the LEDs 77a to 77d (step S3). , The solenoid excitation signal is applied to the solenoid circuit 136, and the drum solenoids 95a ...
95c is turned on (excitation) (step S4), a ramp signal is given to the ramp circuit 140, and the ramps 60, 61a, 61 are fed.
b is turned on or blinked, and an audio signal is further applied to the amplifier 143 to output a sound effect from the speaker 18 to notify that the drum variable display members 71 to 73 are variably displayed (step S5). In addition, the drum solenoid 95
After a to 95c are turned on, the drum-shaped variable display member 71
~ 73 ratchet gears 89-91 and stop lever 9
In order to completely disengage the hook portions 98a to 98c of 7a to 97c, after a lapse of a minute time T1 (100 mS) (step S6), a drum rotation control signal is given to the motor circuit 138. The rotation motor 82 is rotated to start the rotation of the drum-shaped variable display members 71 to 73 (step S7).

Then, in step S8, it is determined whether or not the player has pressed the stop switch 19 after the rotation of the drum-shaped variable display members 71 to 73 is started, and if it is not pressed, Is the next step S9
Then, it is determined whether or not 5 seconds have elapsed from the start of drum rotation. If 5 seconds have not elapsed, the process returns to step S8. In step S8, the stop switch 19 is pressed, or after 5 seconds have elapsed from the start of rotation of the drum without pressing the stop switch 19, one time T2 is randomly selected from 10 different times. Then (step S10), the process proceeds to the next step S11. In step S11, the time T2 selected in step S10
After the elapse, the left variable display member 71 is stopped first. This is because the microcomputer 120 uses the solenoid circuit 13
6 sends an excitation stop signal to the drum solenoid 95
This is done by deactivating a. At the same time, an audio signal is given to the amplifier 143 to output an audio signal indicating that the left variable display member 71 has stopped.
(Step S12). After the variable display member 71 on the left is stopped, one time T3 is randomly selected from 10 different times again (step S13),
After the lapse of the selected time T3, the central variable display member 72
Is stopped (step S14), and a voice indicating that the central variable display member 72 is stopped is generated (step S15). Further, after the variable display member 72 at the center is stopped, similarly, from among 10 times,
One time T4 is randomly selected (step S1
6) After the lapse of the selected time T4, the right variable display member 73 is stopped (step S17), and a sound indicating that the right variable display member 73 is stopped is generated (step S18).

After the three variable display members 71 to 73 are stopped, the microcomputer 120 causes the projector circuit 1 to
A control signal is supplied to the projector 37, and the projectors 100a-100
e is turned on (step S19). Floodlight 100a-
After 100e is turned on and a minute time T5 (0.4 seconds) has elapsed (step S20), it is determined in step S21 whether or not the value of the appearance frequency counter in the specific display state, that is, the big hit state is "0". In step S20, the minute time T5 is passed because the motor 82 is still rotating even when the drum solenoids 95a to 95c are all turned off, so that the deviation of the drum stop position can be eliminated. Is to earn. Also,
When the appearance frequency counter is "0", the fact that the appearance frequency counter is "0" means that the specific display state is determined with the normal probability without increasing the appearance probability of the specific display state. Is the light receivers 101a to 101
e detects the presence or absence of light emitted from the light projectors 100a to 100e, and supplies the detection signal to the microcomputer 120 via the light receiver circuit 135. In the microcomputer 120, the display modes of the drum-shaped variable display members 71 to 73 based on the input signal from the light receiver circuit 135 are a big hit of "5 flatter", "7 flatter" and "9 flatter". It is determined whether or not it is in the state (step S22). That is, when the appearance counter is "0", only three combinations are judged as a big hit state.

If it is not the big hit state, step S2
After turning off (turning off) the projectors 100a to 100e in 3 and stopping the rotation of the rotary motor 82, step S
Return to 2. In this case, if the display form of the variable display members 71 to 73 is not the big hit state but a predetermined display form, the player is given a value different from the big hit as the small hit state. Is also good.

Even when the microcomputer 120 determines the big hit state in step S22, the projectors 100a to 100e are turned off (turned off) and the rotation of the rotary motor 82 is stopped (step S25). In addition,
The probability display 105 provided on the game board 7 always displays, through the digital display drive circuit 142, that the appearance probability of the specific display state is “3/1000” at all times. When the value of the appearance counter is not "0", the appearance probability of the specific display state is "6/100".
It is designed to display that it is "0".

On the other hand, if it is determined in step S22 that the appearance number counter is not "0", in step S24, the input from the photodetector circuit 137 in the microcomputer 120 is performed in order to increase the appearance probability of the big hit. The display mode of the variable display member is “0” based on the signal.
It is determined whether or not it is a big hit state of "doublet", "1 doublet", "3 doublet", "5 doublet", "7 doublet", "9 doublet". That is, the number of display modes that are in the big hit state is increased from three in the normal state to six, and the appearance probability of the big hit state is increased with a high probability. If it is determined in step S24 that the jackpot is not in the big hit state, the process proceeds to step S23, and if it is determined that the jackpot is in the big hit state, the process proceeds to step S25.

In step S22 or step S24, when the microcomputer 120 determines the big hit state, a sound signal is applied to the amplifier 143 to cause the speaker 18 to generate a sound, and a ramp signal is applied to the lamp circuit 140 to supply the lamp 30a. , 30b, 14a, 1
4b, 60, 61a, 61b, etc. are blinked or lit to notify the player of the big hit state (step S26).

Next, after a predetermined time T6 (about 3 to 6 seconds) elapses, in order to improve the feeling of intonation of the player by notifying that the big hit condition has occurred, there is a time margin (step S27). The opening / closing plate 54 of the variable winning ball device 50 is opened (step S28). This is done when the microcomputer 120 gives a control signal to the solenoid circuit 139 and the solenoid 66 is turned on (excited). At this time, 1 is added to the opening number counter that counts the number of times the opening / closing plate 54 is opened. And
The fact that the opening / closing plate 54 is opened is notified by the speaker 18, the lamps 60, 61a, 61b, etc., and the number of times of opening is displayed on the digital display 76 via the digital display drive circuit 142 (step S29).

Next, after the opening / closing plate 54 is opened, it is determined whether or not the balls that have won the variable winning ball device 50 have won the repeated condition winning area 55a (step S3).
0). This is done by sending the detection signal of the V winning ball detection switch 56 to the microcomputer 120 via the V winning ball detection circuit 133. When the microcomputer 120 determines that there is a detection signal from the V winning ball detection switch 56, it is determined whether or not the value of the opening number counter of the opening / closing plate 54 is "10" (step S31). . The value of the opening counter is 10
If not, it is further determined whether or not the V winning ball detection switch 56 has been actuated (step S33). This is the V stored in the RAM 123.
It is determined whether or not the value of the winning storage counter is "1". If the value of the V winning storage counter is not "1", "1" is added to the V winning storage counter and stored (step S34), and at the same time, the V winning display LED 56a, via the LED circuit 141, 56b is turned on to inform the player that there is a V prize (step S35). In the step S31, the opening / closing plate 5
If it is determined that the value of the opening number counter of 4 is "10", and in step S33, the value of V is already V.
If it is determined that the value of the winning storage counter is "1", the V winning ball detection signal is processed as invalid (step S32).

On the other hand, in step S30, if it is determined that the V winning ball detection switch 56 is not turned on or after the processing in step S32 or step S35 described above is completed, the process proceeds to step S36. In step S36, the 10-count detection switch 57 for detecting all winning balls that have won in the variable winning ball apparatus 50.
It is determined whether or not is turned on. Each time the 10-count detection switch 57 detects a winning ball, the detection signal is 1
It is sent to the microcomputer 120 via the 0 count detection circuit 134 and increments by 1 to the 10 count counter provided in the RAM 123 (step S3).
7) Each time the addition is made, a winning sound is generated from the speaker 18 via the amplifier 143, and the winning number is displayed on the digital display 59 via the digital display drive circuit 142 (step S38). When the process of step S38 is completed or when there is no detection signal of the 10-count detection switch 57 in step S36, it is determined whether or not the value of the 10-count counter in the RAM is "10". (Step S39). 10
When it is determined that the value of the count counter is not "10", the solenoid 66 is further turned on (excitation).
After 30 seconds, it is determined whether 30 seconds have passed (step S40). If 30 seconds have not passed, step S40
Returning to step 30, the processing from step S30 to step S40 is repeated.

On the other hand, if it is determined in step S39 that the value of the 10-count counter is "10", or if it is determined in step S40 that 30 seconds have passed since the solenoid 66 was turned on, the microcomputer The 120 sends a stop signal to the solenoid circuit 139 to turn off (demagnetize) the solenoid 66 (step S41). Therefore, the opening / closing plate 54 of the variable winning ball device 50 shifts from the open state to the closed state. Furthermore,
The lamps 60, 61a, 61b are turned off via the lamp circuit 140 to notify that the opening / closing plate 54 is closed (step S42). After closing the opening / closing plate 54, the microcomputer 120 determines whether or not the value of the V winning storage counter stored in the RAM 123 is "1" (step S43). When it is determined that the value of the V winning storage counter is "1", after the solenoid 66 is turned off, a predetermined time T7 (about 3 seconds) is elapsed (step S44), and then the RAM The stored contents of the 10-count counter and the V winning storage counter are cleared (step S45), the process returns to step S28, and the subsequent operations are repeated. In step S44, time T7
This is set in order to increase the processing time of the prize balls whose prize ball payout processing has not ended among the prize balls that have won the prize while the opening / closing door 54 is open.

On the other hand, even if it is determined in step S43 that the value of the V winning storage counter is not "1", it is determined whether or not 2 seconds have elapsed since the solenoid was turned off (step S46). That is, even after the opening / closing plate 54 is closed, the V winning ball detection switch 5
The detection signal from 6 will wait for 2 seconds. This is particularly the case when the last ball that has won the variable winning ball device 50 repeatedly wins the condition winning area 55a, and the player feels that there is a V winning, and the V-detection of the pachinko ball happens to be bad and V detection happens. This is to avoid erroneously determining that there was no V prize when it was late. Therefore, before the lapse of 2 seconds, the process returns to step S43 to confirm whether or not there is a V winning. Also, after 2 seconds have passed, the above-mentioned step S
For the same reason as 44, a predetermined time T7 (about 3 seconds) is made to elapse (step S47), and then the 10-count counter in the RAM 123, the V winning memory counter, and the opening door 54.
The stored contents of the opening counter are cleared (step S48). Further, "1" is added to the stored contents of the jackpot counter also in the RAM (step S).
49). Then, in the next step S50, it is determined whether or not the stored numerical value of the jackpot number counter subjected to the addition processing is "3". The value of the jackpot counter is "3"
If it is determined that it is not, that is, if it is "1" or "2", it means that the specific display state has not been reached the predetermined number of times in the high probability state in which the appearance probability has been increased, and the appearance probability is again determined. In the high probability state in which is increased, the process returns to step S2. On the other hand, if it is determined in step S50 that the value of the jackpot counter is “3”,
Since the specific display state has appeared a predetermined number of times in the high-probability state in which the appearance probability has increased, the stored content of the jackpot number counter is cleared to return the appearance probability to the normal probability (step S51), and then step S2. Return to and repeat the subsequent processing. In step S51,
When clearing the stored contents of the jackpot counter, the microcomputer 120 sets the digital display drive circuit 1
The normal probability is displayed on the probability display 105 via 42.

As is apparent from the above description of the operation, in this embodiment, the appearance probability of the first specific display state is the normal probability that three ditches are produced, that is, "3/1".
000 ”, and when the specific display state appears with the normal probability, the opening / closing plates 54 of the variable winning ball apparatus 50 are opened for 30 seconds or until 10 pieces are won. The open state is repeated, and such repetition is continued up to 10 times to give a value that is profitable to the player. Then, the probability of becoming the specific display state again when the game in the specific display state as described above is finished is a high probability that six ditches are produced, that is, "6.
/ 1000 ". Therefore, the probability of occurrence of the second specific display state is twice the probability of appearance of the first time, which makes the player entertaining. Furthermore, in this embodiment, since the appearance probability of the third specific display state is also an increased high probability, the specific display state may appear at a relatively short time interval for the player, and further, The game is entertaining, and since the specific display state is prevented from being displayed unnecessarily continuously, it is easy for the game hall to manage.

FIG. 17 is a front view showing a second embodiment of the variable display device. The variable display device in the second embodiment is an electric variable display device, and the difference from the variable display device 70 of the first embodiment described above is that the variable display member is a mechanical drum in the first embodiment. In contrast to the shape variable display member, in the second embodiment, it is an electric digital variable display member using a 7-segment LED, and other than this point, it is almost the same.

The main structure of the digital variable display device 200 will be described with reference to FIG. The digital variable display device 200 has three digital variable display members 201 to 203 substantially in the center thereof, and each of the digital variable display members 201 to 203 has a number of 0 to 9 under the control of a control circuit. It is possible to display 10 types of numbers. In addition, the digital variable display device 2
In 00, the number-of-opening display 204, which displays the number of times the opening / closing plate 54 of the variable winning ball device 50 is opened, the variable winning ball device 50.
Number of prize balls display device 20 that displays the number of prize balls won
5. Start winning prize memory display LEDs 206a to 206 for storing and displaying the number of balls won in the starting winning prize holes 52, 11a, 11b
d, and probability display L for displaying the specific display state appearance probability
EDs 207a and 207b are provided respectively. Of these, the probability display LEDs 207a and 207b are each made up of 10 LED lamps, and with normal probability, 3 of 10 LED lamps are turned on,
It informs the player that it is a normal probability, and in the increased high probability, turns on 6 of the 10 LED lamps,
The player is informed of the increased probability.

Next, a method of controlling the increase of the appearance probability in the second embodiment will be described with reference to FIG.
FIG. 18 shows an example of a symbol pattern displayed on the digital variable display members 201 to 203 in the second embodiment. In the figure, in the digital variable display members 201 to 203, a state in which 10 numbers 0 to 9 are variably displayed one by one at relatively short time intervals is adopted as one cycle, and the cycle is repeated at high speed. ing. The data A is displayed during the variable display during normal operation. That is, the digital variable display member on the left side has "2" out of 10 numbers from 0 to 9.
Since the display is changed from "4" to "7", the probability that "7" is displayed at the time of stopping is "3".
/ 10 ”. Further, since 10 numbers from 0 to 9 are sequentially displayed on the central and right digital variable display members 202 and 203, "7" is displayed when the display is stopped. Each probability is "1/1
It becomes "0". Therefore, in the three digital variable display members 201 to 203, the probability that "7, 7, 7" is displayed as the specific display state is "3/1000" which is obtained by multiplying them. By the way, after the first specific display state appears with the above-described normal probability “3/1000”, the control circuit controls so as to increase the second and subsequent appearance probabilities. Then, as a method to control so that the appearance probability increases. As shown in data B and data C, three digital variable display members 201-203
Of these, only the number pattern displayed on the central digital variable display member 202 may be changed. That is, as shown in data B, “6” is changed to “7” among the numbers 0 to 9 and the “7” is continuously displayed (doubled in time). Or as shown in data C,
"2" is changed to "7" and displayed, and "7" is displayed in one cycle.
Is displayed twice, the probability of displaying “7” on the central digital variable display member 202 is “2/1.
It becomes "0". Therefore, the probability that "7, 7, 7" as the specific display state is displayed on the three digital variable display members 201 to 203 is "6/1000" by multiplying them. Also in the second embodiment, as in the first embodiment, when the specific display state appears twice with an increased high probability, the operation of the appearance probability increase control means ends and the normal probability is restored. Therefore, the average probability of the whole does not exceed the value of the constant appearance probability (1/200) which is generally set in the past.

Also in the second embodiment, as in the first embodiment, the digital variable display members 201 to 2 are used.
In 03, the numbers 0 to 9 are variably displayed in order, and the normal specific display state is "5, 5, 5""7,
There are three types of "7, 7" and "9, 9, 9", and after the appearance probability increasing means is activated, in addition to them, "0, 0, 0"
It is also possible to determine that "1, 1, 1" and "3, 3, 3" are also in the specific display state, and control them so that there are a total of 6 types. The control circuit and operation of the second embodiment are substantially the same as those of the first embodiment if the drum part and the digital part, which are the differences from the first embodiment, are replaced, and therefore the block diagram of the control circuit and A flow chart showing the operation is omitted.

The above-mentioned first and second embodiments are
In both of them, the specific display state is made to appear by combining a plurality of variable display members, but the specific display state may be made to appear by using one variable display member.

FIG. 19 is a front view showing a third embodiment of the variable display device. The variable display device in the third embodiment is the same electrically variable display device as in the second embodiment described above. Although three are arranged side by side,
The third embodiment is characterized in that a total of nine digital displays are arranged by arranging three columns vertically and horizontally.

The main structure of the line display type variable display device 300 of the third embodiment will be described with reference to FIG. Near the center of the line display type variable display device 300,
Nine digital display units 301 to 309 (A to I; used when explaining a flow chart described later) are arranged in vertical and horizontal three columns, and each digital display unit 301 to 309.
Can display 10 kinds of numbers from 0 to 9 under the control of the control circuit. However, in this case, three digital displays 301 to 303, 3
Since 04 to 306 and 307 to 309 are controlled so that the numbers move in order from the top, when viewed from the front,
The numbers appear to rotate at high speed. Further, on each of the left and right sides of the digital display row, a pair of five hit line indicators 310a to 310e are vertically arranged. That is, the three horizontal digital displays 302, 305 in the center,
A line display (LED) 310a that connects 308 to form a line “a”, a line display 310b that connects three horizontal upper digital displays 301, 304, and 307 to form a line “b”, and a lower line display 310b. A line display 310c that connects the three horizontal digital displays 303, 306, and 309 to form a line "c" and a digital display 301, 305, and 309 that are arranged diagonally to the upper left to connect the line "d" The constituent line display 310d and the digital displays 303, 305, 30 arranged diagonally downward to the left
A line indicator 310 that connects 7 to form a line "e"
e and are provided. In addition, the line display type variable display device 3
00, a number-of-opening display 311 that displays the number of times the opening / closing plate 54 of the variable winning ball device 50 is opened is also provided.

Explaining the appearance probability of the specific display state of the line display type variable display device 300 as described above,
Normally, "7, 7, 7" or "9," on line "a"
When the display of "9, 9" is lined up, it is set as a specific display state. Therefore, as described in the first embodiment, the probability that "7, 7, 7" are aligned in a horizontal row is "1.
Since it is "/ 1000", the probability that two ditches are lined up is "2/1000". At this time, the line display 310a of the line "a" is turned on to notify the player of an effective hit line.

By the way, after the first specific display state appears with the above-mentioned normal probability "2/1000", the control circuit controls so as to increase the second and subsequent appearance probabilities.
First, in the line display type variable display device 300, the second appearance probability increasing method is to enable three lines “a” to “a”, “b”, and “c” as the winning lines. It is done by controlling. Therefore, the probability that "7, 7, 7""9, 9, 9" will appear on these three hit lines "a", "b", "c" is
Since it is three times the probability of the first time, it becomes “6/1000”. Furthermore, the third appearance probability increasing method is to increase the number of hit lines and to control the five lines “a”, “b”, “c”, “d”, and “e” to be valid as hit lines. Done. At this time, the probability that the above-mentioned two double stitches appear on these five hit lines is 5 times the probability of the first time, and is therefore “10/1000”.
Also in this third embodiment, as in the first embodiment, when the specific display state appears twice with an increased high probability,
The operation of the appearance probability increase control means ends, and the normal probability is restored. And the probability of the first time is "2/10
00 → 500 times, 1 occurrence ”, 2nd probability: 6/10
00 → 166.5 times, 1 occurrence ”, 3rd probability: 10
/ 1000 → 100 occurrences once ", and the overall average probability becomes" 3 / 766.5 → 255 occurrences once ", which is a constant occurrence probability (1 /
200) is not exceeded.

Further, the above-mentioned game contents are characterized in that, if the viewpoint is changed, the display contents of the game change as the probability increases. That is, at normal probability,
While the player pays attention to only one hit line “a”, he / she plays three hit lines “a” “b” “c” or five hit lines “a” at the time of high probability after the second hit. "
Since the game is played by paying attention to "b", "c", "d", and "e",
From the player's point of view, he / she has the impression that he is playing a different game, which can further attract the player's interest. In this case, the fact that the game is different is displayed by the hit line indicators 310a to 310e, so that the player can easily understand the change in the game content.

FIG. 20 is a block diagram of a control circuit configuration for controlling the third embodiment. This control circuit is almost the same as the control circuit of the first embodiment shown in FIG. 13, and only different points will be described. The same components as those shown in FIG. 13 are designated by the same reference numerals. The configuration of the microcomputer 120 is exactly the same as that of FIG. 13, but the types of input signals received by the microcomputer 120 and the types of control signals sent from the microcomputer 120 are different. The input / output signal will be described below.

The following signals are given to the microcomputer 120 as input signals. First, the detection signals of the start prize winning ball detection switches 33, 34a, 34b provided corresponding to the start prize holes 52, 11a, 11b are given to the start prize detecting circuit 131, and the microcomputer 120 starts the start prize balls. A detection signal is given. The detection signal detected by the stop switch 19 is given to the stop circuit 132 and given to the microcomputer 120 as a stop signal. The detection signal detected by the V winning ball detection switch 56 is the V winning ball detection circuit 13
3 and the repetitive signal to the microcomputer 120. 10 count detection switch 57
The detection signal detected in 1 is given to the 10-count detection circuit 134, and given to the microcomputer 120 as a winning ball number counting signal.

The microcomputer 120 also supplies control signals to the following circuits and devices. First, a variable display drive signal for variably displaying the digital displays 301 to 309 (A to I) of the line display type variable display device 300 is given via the digital display drive circuit 350. The hit line display 310a is passed through the hit line display drive circuit 351.
A control signal for lighting or blinking ~ 310e is given. A drive signal is given to the solenoid 66 via the solenoid circuit 139 to open / close the opening / closing plate 54. Through the lamp circuit 140, the frame lamps 30a and 30b, the specific display state notification lamps 14a and 14b, and the decorative lamps 60 and 61
A control signal for lighting or blinking a and 61b is given. Via the LED circuit 141, the starting winning opening 52,
LEDs 77a to display the number of winnings in 11a and 11b
77d and the control signal for turning on the V winning display LEDs 56a and 56b indicating that the winning is made in the repetitive condition winning area 55a. A control signal for displaying the digital displays 311 and 59 is given through the digital display drive circuit 142. Furthermore, the sound effect is reported from the speaker 18 via the amplifier 143.

21 to 23 are flow charts showing the operation of the control circuit shown in FIG. Note that FIG. 22 and FIG. 23 are exactly the same as FIG. 15 and FIG.
Therefore, a specific operation of this embodiment will be described with reference to FIGS. 1 to 3 and 19 to 23.
First, when the power supply of the control circuit is turned on, the microcomputer 120 initializes the stored contents of the LED circuit 141 (step S1) and waits for the next signal. By the way, when the processing of step S1 is completed, the microcomputer 120 is processed so that the interrupt routine shown in FIG. 22 is always interrupted. This interrupt routine
4m from pulse division circuit (interrupt pulse generation circuit) 129
The processing of steps S49 to S53 is performed based on the signal interrupted for each S. That is, it is determined whether or not the pachinko ball in the game has won in any of the starting winning openings 52, 11a, 11b.
It is determined based on the detection signals of a and 34b (step S4
9) If any of the starting winning openings 52, 11a, 11b has been won, it is further determined whether or not the line display type variable display device 300 is performing variable display (step S5).
0). When the variable display is being performed, the fact that the winning prize has been started is notified from the speaker 18 via the amplifier 143 (step S51). After the notification, or when the line display type variable display device 300 is not variably displaying, it is determined whether or not the value of the start winning award storage counter stored in the RAM 123 is "4" (step). S52), if it is not "4", 1 is added to the numerical value stored in the starting winning prize memory counter, the LEDs 77a to 77d are turned on via the LED circuit 141 (step S53), and the interruption is ended. On the other hand, step S
If there is no detection signal from the start winning detection switches 33, 34a, 34b at 49, and if the numerical value stored in the starting prize storage counter is "4" at step S52, the interruption ends. The microcomputer 120 always performs an interrupt process from step S49 to step S53.

On the other hand, returning to the main routine for explanation, after being initialized in step S1, first,
It is determined whether or not the value of the jackpot (specific display state) number counter stored in the RAM 123 of the microcomputer 120 is "0" (step S2). When the value of the number of big hits is "0", since it is the first big hit, only the combination displayed on the line "a" which is the normal probability is validated (step S4). At this time, the microcomputer 120 turns on or blinks the hit line indicator 310a (LED) via the hit line display circuit 351. On the other hand, when the value of the big hit number counter is not "0", it is further determined whether or not the value of the big hit number counter is "1" (step S3). If it is determined that the value of the number of big hits is "1", it means that the first appearance probability is increased, and therefore three lines "a" to "c" are activated ( Step S5)
And hit line indicators 310a, 310b, 310
Turn on or blink c. Further, when it is determined that the value of the jackpot counter is not "1", the five appearance lines "a" to "e" are activated because the second appearance probability is in an increasing state (step S6)
And hit line indicators 310a, 310b, 310
C, 310d, 310e are turned on or blinked. Then, step S4, step S5, and step S6
With the line activation set in, the game is started on the pachinko gaming machine 1, a pachinko ball is driven into the game area 9 of the game board 7, and the driven pachinko ball is
Depending on the processing performed by the interrupt routine, it is determined whether or not the value of the start winning a prize memory counter is "0" (step S7). The value of the starting prize winning memory counter is "0"
In the case of, this determination is repeated. If the value of the starting winning prize memory counter is not "0", the microcomputer 1
20 first subtracts "1" from the start winning prize memory counter, turns off one of the LEDs 77a to 77d in response to this (step S8), and thereafter gives a digital display drive signal to the digital display drive circuit 350, Variable display of the digital displays 301 to 309 is started (step S
9), the ramp signal is given to the ramp circuit 140 and the ramp 6
0, 61a, 61b are lit or blinked, and a sound signal is applied to the amplifier 143 to cause the speaker 18 to produce a sound effect to notify that the line display type variable display device 300 is performing variable display (step S10). ).

Then, in step S11, it is determined whether or not the player has pressed the stop switch 19 after the variable display of the digital displays 301 to 309 (A to I) is started, and if it is pressed, it is determined. If not,
In the next step S12, it is determined whether or not 5 seconds have elapsed since the start of variable display. If 5 seconds have not elapsed, the process returns to step S11. In step S11, the stop switch 19 is pressed or the stop switch 19 is pressed.
Without being pressed, digital displays 301-309
After 5 seconds have elapsed from the start of variable display of (A to I), 1
One time T1 is randomly selected from 0 kinds of time (step S13), and the process proceeds to the next step S14.
In step S14, after the time T1 selected in step S13 has elapsed, the digital display 301 in the left column is first displayed.
(A), 302 (D) and 303 (G) are stopped. At the same time, an audio signal is given to the amplifier 143 to generate an audio from the speaker 18 indicating that the digital displays A, D and G in the left column are stopped (step S15). After the digital displays A, D, and G in the left column stop, again from among the 10 times, randomly select 1
One time T2 is selected (step S16), and after the selected time T2 has elapsed, the digital display 304 in the center column
(B), 305 (E), and 306 (H) are stopped (step S17), and at the same time, a sound indicating that the digital indicators B, E, and H in the center row are stopped is generated (step S18). . Further, after the digital displays B, E, H in the center row are stopped, one time T3 is randomly selected from the 10 times in the same manner (step S
19), after the lapse of the selected time T3, the digital displays 307 (C), 308 (F), 309 (I) in the right column.
Is stopped (step S20), and at the same time, a sound indicating that the digital displays C, F, I in the right column are stopped is generated (step S21).

Then, all the digital displays A to I
After the stop, the microcomputer 120 determines whether or not there is a specific display of "7, 7, 7""9, 9, 9" on the lines activated in steps S4 to S6 ( Step S22). When it is determined that the specific display is not present on the activated line, the process returns to step S7. On the other hand, when it is determined that the specific display is on the activated line, the process proceeds to the next step S23 in order to give the player a profitable value.

The processing from step S23 to step S48 shown in FIG. 23 is performed by step S2 shown in FIG.
Since it is exactly the same as the processing from 6 to step S51,
The description is omitted.

As is apparent from the above description of the operation, in the third embodiment, the appearance probability of the first specific display state is the normal probability that two ditches appear on one line "a", that is, When the specific display state appears with the probability of "2/1000", the opening / closing plate 54 of the variable winning ball device 50 is opened for 30 seconds or until 10 pieces are won, and if there is a V winning ball during the opening, Repeat the above-mentioned open state again, continue such repetition up to 10 times,
It provides value that is profitable to the player. And
The probability of returning to the specific display state after the game in the specific display state as described above is finished is three lines “a”
It is controlled so that there is a high probability that two ditches appear on “b” and “c”, that is, “6/1000”. Therefore, the appearance probability of the second specific display state is three times as high as the appearance probability of the first time, which makes the player entertaining. Further, in this embodiment, the probability of the third specific display state is five lines “a” and “b”.
It is controlled so as to have a high probability that two ditches are generated in “c”, “d”, and “e”, that is, “10/1000”. Therefore, the appearance probability of the third specific display state is five times the first appearance probability, and the specific display state may appear at an extremely short time interval for the player.
It has become an even more entertaining game. Especially, in the case of the third embodiment, unlike the case of the first embodiment, since the appearance probabilities of the specific display state are set to increase in sequence, the player is expected to have a sense of expectation. It has become a game. In addition, as the change of the display content of the game, the winning line is shown to be sequentially increased to "1""3""5", but the display content may be changed by another method. However, even in this case, it is necessary to make it easy for the player to know that the change has been made.

In the above-mentioned three embodiments, the variable display device employs the mechanical drum type variable display member and the electrical digital type variable display member. Not limited to this, for example, a leaf-type variable display member may be adopted as the mechanical variable display member, and further, as the electrically variable display member, a device that variably displays by blinking movement of LED lamps or LCD ( It may be a variable display using a liquid crystal). Also, a mechanical display drum may be used as the line display type variable display device as in the third embodiment. Further, it may be a combination of a mechanical variable display member and an electrical variable display member.

Further, in each of the embodiments, the variable winning ball device is exemplified as the predetermined value, but another winning ball device may be used, or a large amount of prize balls may be directly discharged. good. In short, in the ball game, any value may be used as long as it is a value that is profitable to the player.

In addition, as a display mode of the variable display device, in a normal state, a variable display is always performed in order to give a decorative effect, and a display mode for displaying a specific display state from the time of winning the start winning opening. Therefore, the variable display may be started. At this time, for example, the original variable display (started by winning at the start winning port) is performed so that the decorative variable display and the variable display as the original function of the variable display device can be distinguished. It is preferable to turn on a notification lamp to that effect.

In the above-mentioned three embodiments, the condition for ending the operation of the specific display state appearance probability increase control means is limited by the number of appearances of the specific display state. However, the condition is not limited to this. For example, the operation of the specific display state probability increase control means may be terminated when a predetermined time has elapsed from the start of the operation, or the variable display device has been operated a predetermined number of times. When it becomes the specified display mode,
You may make it each operation end.

[0069]

As described above, according to the present invention, when the first specific display state appears, a predetermined value is given to the player, and the appearance probability of the specific display state a predetermined number of times from the next time is first calculated. Since it is made to increase more than the appearance probability, when the first specific display state appears, the next specific display state appears at a relatively short time interval, which is more interesting for the player. A game can be provided. Further, since the high probability state does not continue unnecessarily, and the number of appearances of the specific display state in the high probability is limited without updating, it is possible to provide a ball game machine that is easy to manage even for a game arcade. In addition to being able to do so, the specific display state does not continuously appear more than necessary.
