Description

[Detailed description of the invention]

[00011

[Industrial Field of Application] The present invention relates to a bay saw machine equipped with a separate gaming means such as a variable display device and a variable prize winning device. [0002] [Prior Art] Conventionally, in this type of pachinko machine, when a hit ball flowing down the game board enters a specific winning hole, a separate game is played on a variable display device, and special conditions set in advance are set in this separate game. When this is achieved, the receiving state of the batted ball of the variable winning device changes from the second state, which is disadvantageous to the player, to the first state, which is advantageous to the player, and in this first state, the ball that has flowed into the variable winning device enters the continuous winning hole. A system has been proposed in which the first state is repeated when a prize is won. [0003] Problems to be Solved by the Invention However, in the conventional pachinko machine described above, the probability that the special condition is achieved with the variable display device is fixed at a predetermined value from the time the pachinko machine is manufactured. This probability cannot be adjusted externally, and once a special game occurs due to the achievement of a special condition, it will bring a large profit to the player. There is a tendency to suppress the occurrence of special games by suppressing winnings of balls hit into the winning hole. However, if winnings from the starting slot are suppressed, the features of the pachinko machine cannot be utilized, making it unattractive for large profits, or limited to a very small number of skilled players. However, there was a problem in that profits were unevenly distributed. [0004]

[Means to solve the problem]

Therefore, the present invention is aimed at achieving the above object, and the contents thereof will be explained below using embodiments shown in the drawings. A pachinko machine includes specific state detection means (for example, detectors 10a to 10c') for detecting a specific state of a batted ball, and separate game means (for example, a variable display 11a) that starts operating when the specific state detection means detects a specific state. ~11c) and
A special condition determining means (for example, the determining circuit 41) that determines whether the special condition has been achieved based on the game result of the separate gaming means; ) to a state advantageous to the player based on predetermined conditions (for example, a flip-flop 46a, a timer 52a).
etc.), and if it is determined that the continuation condition due to the batted ball is achieved during the conversion operation of the variable winning device, the continuation condition causes the drive control means to continue the variable winning device again to perform the conversion operation. Discrimination means (for example, special switch 30,
(flip-flop 55, etc.) and a termination condition that is achieved in relation to a batted ball flowing down inside the game section flowing into a specific hole, and if this termination condition is achieved during the special game, A target profit rate that can be given to the player based on the result of the special game ending in the cycle and the ending condition determining means (for example, the stop switch 60, the flip-flop 62, etc.) and the above-mentioned separate gaming means is controlled by an external operation. Target profit rate setting operation means that is set in multiple stages (for example, connection lines 67a to 67c)
), and special condition achievement probability control means (for example, 'WJ
D gates 35a to 35c, oscillators 36a to 36c, and counters 37a to 37C). [0005]

[For use]

When the specific state of the hit ball flowing down inside the game section of the game board 6 is detected by the specific state detection means 10a to 100',
Special condition achievement probability control means 35a-35c, 36a-36c, 37a-3 at a frequency based on the target profit rate set by target profit rate setting operation means 67a-67c.
Under the control of 7c, the separate gaming means 11a to 11C start operating. If the special condition determining means 41 determines that the special condition has been achieved based on the game results of the separate gaming means, one variable prize winning device 13 is activated by the drive control means 46a, etc.
Is it a special game that converts into the first state advantageous to the player? Start. During this conversion operation, if the continuation condition determining means 30 determines that the continuation condition has been achieved by hitting the ball, the drive control means causes the variable prize winning device to continue the conversion operation again, and the special game is started. Update cycle. On the other hand, during the conversion operation of the variable prize winning device, that is, during the special game,
When the termination condition determination means 60 or the like determines that a preset termination condition has been achieved in connection with the hitting of the ball, the drive control means operates to convert the variable prize winning device into a second state disadvantageous to the player. This causes the special game to end in this cycle. [0006]

【Example】

The present invention will be explained below based on embodiments shown in the drawings. In FIG. 1, a pachinko machine 1 has a ball supply tray 2 on its surface, and a player inserts a ball from the supply tray 2 into an operating section 3.
When operated, the firing device 4 is activated, and the balls placed in the supply tray 2 are fired one after another. The shot ball is guided above the game part 7 on the surface of the game board 6 through the guide rail 5, and flows down the game part 7 while hitting an obstacle nail. Then, if you enter the prize opening 8 on the way down, it will be safe,
A prize ball discharging mechanism (not shown) provided on the back side of the game board 6 is activated, and a certain number of prize balls are discharged into the supply tray 2 or the receiving tray 2' provided below on the surface of the pachinko machine 10. However, if the batted ball flowing down the gaming section 7 does not enter any of the winning holes 8, it enters the out opening 9 provided at the lower end of the gaming section 7 and is confiscated. In the gaming section 7 described above, specific conditions to be achieved by hitting a ball are set. According to the embodiment of the drawings, this time-fixed condition is based on the left and right specific winning openings 10a provided above the gaming section 7,
This is achieved by detecting that the hit ball enters one of the slots 10b or that the ball passes through the specific prize winning frame 10c provided below the gaming section 7. Since it is preferable that this specific condition is not easily achieved, it is preferable to make it difficult for a hit ball to enter the specific winning slots 10a, 10b or to make it difficult for a hit ball to pass through the specific winning slot 10c by using an obstacle nail. Each of the specific winning slots 10a, 10b and the specific winning slot 10c is provided with a switch mechanism as a specific state detection means, and when a ball hits or passes, the switch mechanism is momentarily turned on and the specific condition is met. Detecting Achievement 2 [0007] It is detected that the hit ball happens to enter one of the specific winning holes or passes through a specific winning valve. According to the embodiment of the drawings, this separate game is performed using three variable displays 11a as separate game means.
This is done by rapidly changing ~llc. Each of the variable indicators 11a to llc has a number of 10 from "1" to "10".
This can be done mechanically by rotating a drum or disk displaying numbers at high speed, or by electrically controlling a segment display with seven segments arranged in a "day" shape. This may be done by rapidly changing the numbers from "1" to "0". [0008] In any case, when a specific condition is achieved by hitting a ball, another game starts on the variable displays 11a to 11C, and this other game continues for a predetermined time (for example, 7 seconds). When the player operates the stop switch 12 on the table 100 of the pachinko machine 1 within this predetermined time, each of the variable indicators 11a-l
The high-speed change of lc stops intermittently, and the window hole changes from "1" to "
Any number up to 0 will be displayed.

[0009] Furthermore, the player presses the stop switch 12 within a predetermined time during another game.
If the player does not operate the stop switch 12, the high-speed change of each of the variable indicators 11a to 11c will be stopped intermittently by electrical means immediately after the end of the predetermined time, resulting in the same state as if the player had operated the stop switch 12. [00101 As a result of the completion of another game in this way, if the special conditions are satisfied, a special game will start and bring a large profit to the player, and if the special conditions are not satisfied, the player will receive a small profit. And it doesn't bring it. This special condition is, for example, a case where all the numbers "7" are aligned and stopped in the window holes of each of the variable indicators 11a to 11c, and there is no special condition in other cases. This special condition applies to each variable display 11a to 1
The special condition determining means determines the stopped state of 1c. [0011] When the special conditions are achieved through a separate game, a special game starts in the gaming section 7 and can bring great profits to the player.

[0012] In this special game, the embodiment of the drawing is a variable winning device provided in the game section 7, and this state is maintained for a certain period of time (
[001
3] This special variable prize winning device 13 has a horizontally long opening 14, and guide pieces 15a to 15e are provided at a certain distance below the opening 14 on the right and left sides, and guide pieces 15a to 15e are provided on the left and right sides above the opening 14. Guide pieces 16a to 16b are provided. [0014] The linear guide pieces 15a and 15b are electromagnets 17a provided on the back surface of the game board 6. 17b. That is, each electromagnet 17a, 17b
The tips of the rods 18a, 18b are connected to the operating rods 19a, 1
The pins 22a and 22b of the swing rods 21a and 21b, which are pivoted to the base end of the pivot rod 9b and whose base ends are pivoted to the operating frames 20a and 20b provided at the tips of the operating rods 19a and 1.9b, are fitted, and the swing Support pins 23a and 23b provided at the ends of rods 21a and 21b are passed through the game board 5 and protruded from the surface,
Guide pieces 15a are provided at the protruding ends of the support pins 23a and 23b,
15b is attached, and each support pin 23a, 23b passes through an arcuate hole 24a, 24b. [0015] In the demagnetized state of each electromagnet 17a, 17b, the support pin 23
a, 23b are located at one end of the arcuate holes 24a, 24b,
Each guide piece 15a, 15b is located below the opening 14 in a separated state. Therefore, most of the batted balls flowing down the gaming section 7 cannot enter the opening 14, and this state is a second state disadvantageous to the player. [0016] However, when each electromagnet 17a, 17b is excited, the rods 18a, 18b are attracted, and the actuating rods 19a, 19b
As the turning rods 21a and 21b turn, the respective guide pieces 15a and 15b at the tips of the turning rods 21a and 21b move along the arcuate holes 24a and 24b, and each guide The piece 15a15b is located (dashed line in FIGS. 2 and 3). This state is a first state advantageous to the player, and the hit ball flowing down the gaming section 7 rolls through the opening 14 along the guide pieces 15a, 15b, and becomes a safe ball. Therefore, the special game is for each electromagnet 17a, 17
When the electromagnets 17a and 17b are demagnetized, they return to their original state due to the bias of the spring and their own weight, and the special variable winning device 13 returns to the second state which is disadvantageous to the player. [0017] Note that each of the auxiliary guide pieces 16a and 16b is the same as the guide piece 1.
Similarly to 5a and 15b, it is connected to auxiliary electromagnets 25a and 25b provided on the back side of the game board via auxiliary operating rods 26a and 26b and auxiliary turning rods 27a and 27b, and when auxiliary electromagnets 25a and 25b are demagnetized, Although each auxiliary guide piece 16a, 16b is located above the opening 14, when the auxiliary electromagnet 25a, 25b is excited, each opening 1
Located on the side edge of 4. In addition, this auxiliary guide piece 16a, 1
The action of 6b will be described later. [0018] As described above, when the special condition is achieved by a separate game, the electromagnets 17a and 17b are excited, and the guide pieces 15a and 15b are positioned at the lower side of the opening 14, so that the special variable prize winning device 13
is converted into the first state advantageous to the player, a special game starts, and the batted balls flowing down the game section 7 are likely to continuously enter the opening 14 and become safe balls. [0019] The opening 14 has a continuation port 28 into which it is relatively difficult for a batted ball to enter, and if a ball that enters the opening 14 during a special game happens to enter the continuation port 28, the core ball is It flows down the special flow path 29 and is detected by the special switch 30 as one component of the continuation condition determining means. [0020] When the special switch 30 detects the ball in the channel 29, after the special game ends for a certain period of time, the second special game continues for a certain period of time. That is, when the ball enters the continuation port 28 during the special game and the special switch 30 is turned on, the continuation condition is achieved,
Immediately after the energized electromagnets 17a and 17b are demagnetized, they are energized again, and the second special game is repeated for a certain period of time. [0021] Then, when a ball enters the continuation port 28 during the second special game and is detected, the third special game is played after the second special game ends.
The special game is repeated. Therefore, the special game will be repeated many times if the continuation condition is achieved during a certain period of time. [0022] However, if the continuation condition is not achieved due to the batted ball entering the opening 14 during the special game within a certain period of time, the special game ends at the time when the special game ends. In this way, if the batted ball achieves a specific condition in the game section 7, another game will occur, and if the special condition is achieved in another game,
A special game that can bring significant profits to the player occurs, and if a continuation condition is achieved while the special game continues for a certain period of time, the special game is repeated again after the special game ends. Therefore, the special game will be repeated as many times as the special conditions are achieved. [0023] Therefore, in the present invention, a termination condition that is achieved in relation to a batted ball flowing down inside the gaming section 7 flowing into a specific area is set in advance, and this termination condition is achieved during the special condition. In this case, even if the continuation condition is achieved, the special game is ended at that time. According to the embodiment shown in the drawings, this termination condition is established when a hit ball is detected to have entered either of the left and right specific holes 31 provided above the gaming section 7. For example, one or more specific holes 31 may be provided at a position where a hit ball is likely to flow down. Also, specific hole 3
1 is provided with a switch mechanism as a component of the termination condition determining means, and when a ball is hit, the switch mechanism is momentarily turned on and detects the establishment of the termination condition. [0024] When the end condition is achieved by a hit ball entering the specific hole 31 and being detected during the special game, another hit ball enters the continuation hole 28.
Even if the continuation condition is achieved by entering and being detected, the electromagnets 17a and 17b will no longer be energized after a certain period of time of the special game, and the special game will end at that time. [0025] Next, a description will be given using the block diagram of the control circuit shown in FIG. The batted ball flowing down the gaming section 7 enters the specific winning holes 10a and 10b.
A Japanese Patent Publication Publication No. 1999-3 that enters or passes through a specific winning opening 10c and faces each winning opening 10a, 10b or winning slot 10c.
-268773 (1G) When a specific condition is achieved by detection by the detectors 10a to 100' as steady state detection means, the output of any one of the detectors 10a 10c is sent from the OR gate 32 to the register 33. The signal is input, and the flip-flops 34a to 34c are set. [0026] As a result, the low level of the Q output of each flip-flop 34a to 34c becomes high level, and this high level signal is given to the individual power of the AND gates 35a to 35c connected individually, so that each oscillator 36a to Every time there is a signal from 36c, a check signal is input to decimal counters 37a to 37c. When this check signal is received, each 10
The advance counters 37a to 37c are 1, 2, . ...9. Variable display devices 11a to 11c that variably transmit the output of O at a speed that corresponds to the frequency of the oscillator, transmit this output variably at a speed that corresponds to the frequency of the oscillator, and configure another gaming means via the driver. given to. [0027] Therefore, each variable display device 11a-11c has a value from "1" to "1".
Converts numbers up to 0 at high speed without being visible. This state is a separate game, and this separate game lasts for a certain period of time (for example, 7
seconds) continue. [0028] When the player operates the stop switch 12 within a certain period of time in this separate game, an input is input to the reset side of the flip-flop 34c via the OR gate 38, and the flip-flop 3
4c, the Q output becomes low level, so the AND gate 35c whose input is connected to this Q output is closed, and therefore 10
The advance counter 37c stops at the number it was counting just before the AND gate 35c closed, and the variable display 11C enters a state where it displays that number. [0029] On the other hand, since the inverted Q output becomes a high level due to the state reversal of the flip-flop 34c, the timer 39b connected to this output operates, and the timer 39b operates for a predetermined period of time.
For example, a high level output is generated after one second has elapsed. Since this output is given to the reset input of the flip-flop 34b, it is first set to 1 by the same action as the flip-flop 34c.
The 0-base counter 37b stops and the number is displayed on the variable display 11.
At the same time, another timer 39a is operated by the inversion of the inverted Q output of the flip-flop 34b. The output of this timer 39a is connected to the reset input of the remaining flip-flop 34a, so when the predetermined time set in this timer, for example 1 second, passes, the high level output from the timer 39a causes the flip-flop 34a to The state is also reversed. Therefore, as before, the decimal counter 37a counts a fixed number and stops outputting it, so the corresponding variable display 11a also stops displaying that number. [0030] A timer 40 is connected to the Q output of the flip-flop 34C that is first reset by the operation of the stop switch 12, and this output is connected to the reset input of the flip-flop 34c via the OR gate 38. Therefore, the timer 40 starts operating at the same time as the flip-flop 34c is set. Then, after a certain period of time set in the timer 40 has elapsed (for example, after 7 seconds), the state of the flip-flop 34C is forcibly reversed, and the above-described circuit operation occurs. This may be caused by the player inadvertently or intentionally
Even if 2 is not pressed, the purpose is to return the circuit system including the counter to the initial state after the time set by the timer 40 has elapsed, in other words, to end another game, and if the timer 40 is not present, the stop switch 12 The other game will continue unless you operate. [0031] When each of the decimal counters 37a to 37c outputs a predetermined count value and stops as described above, a binary coded decimal output, that is, each 4 bit with a weight of 1-2-4-8 is output. The output is input to a comparator or discrimination circuit 41, which is a combination of ordinary matching circuits, as special condition discrimination means. This discrimination circuit 41 transmits first, second, and third outputs. For example, the first output 42a is a case in which all counter outputs have reached a predetermined decimal value, such as "7" (all three phases of the display are set to "7"), which means that a special condition has been achieved. The second output 42b is the counter 37c, 37
The decimal value of the output of only b is the same (i.e. variable display 11
c, llb only power “1” and rlJ, r4J and “4”
etc.), the third output 42c is emitted in the other case. [0032] When the first output 42a is transmitted, a special game is started. That is, this first output 42a is applied to one input of an AND gate 43a, the other input of which is finally reset with respect to the counter. It is connected to the inverted Q output of a flip-flop 34a as one component of the drive control means. [0033] Therefore, the AND gate 43a is opened, and the other input of the other AND gate 45a is connected via the OR gate 44 to the flip-flop whose set input is connected to the output of the flip-flop 46a whose set input is connected to the output of this AND gate 45a. Since it is receiving the inverted Q output of the pulley 46a, the AND
Gate 45a takes AND, flip-flop 46a
is inverted and makes the Q output high level. Of course, at the same time, the inverted Q output of the flip-flop 46a becomes low level, so the AND gate 45a that set the flip-flop 46a is closed at this point. When the flip-flop 46a is set in this way,
The high-level Q output is given to the single input of the three-input AND game (46a). [0034] On the other hand, the other input which is the inverting input of this AND gate 47a is a 4-bit parallel output terminal (for convenience, 0.1 from the lowest , 2. The shift register 48a receives feedback from the most significant bit (No. 3) of the shift register 48a with a number of 3), and this input is an inverted input. Since the flip-flop 46a is inverted and reset by the low-level Q output in the non-set state, the AND game 47a is controlled by the remaining input. Since the output of an oscillator 49 that emits a high-level pulse signal at an appropriate frequency is connected to the last input of the AND gate 47a, the output of the AI'JD gate 47a becomes high level according to this frequency. , each time the shift register 48a changes the output to "1" or high level one bit at a time. This continues until the highest pitch (NO13), but the process is as follows: No, 1 output is OR game)5
The driver 51b is operated via 0a, and the electromagnet 17a is excited. [0035] And, a) Due to the delayed high level transition of the NO12 output, the driver 51c is activated via the OR gate 50b,
Electromagnet 17b is excited. Furthermore, when No. 3 output becomes high level, AND game)
Since the inverting input of 47a is inverted, the corresponding AND gate 4
7a is closed and all bits of shift register 48a are "1"
and stops. [0036] Therefore, since the bichamber magnets 17a and 17b continue to be excited,
The special game continues with each guide piece 15a, 15b located at the lower side of the opening. [0037] The continuation of this special game is ended in a certain period of time by a timer 52a, which is a component of the drive control means, which is activated by the high level transition of the output of N003 of the shift register 48a.
It is. [0038] That is, after the timer 52a is activated (after the electromagnets 17a, 17b are energized), a high level output is generated when a predetermined period of time (for example, 30 seconds) has elapsed. This output is given to the output of an AND gate 53a whose output is connected to the reset input of the flip-flop 46a, and the input power of the AND gate 53a is already at a high level due to the feedback of the Q output of the flip-flop 46a. Therefore, a mutual AND operation is performed, and the flip-flop 46a is reset by the output of the gate 53a. The AND gate 53a, which was reset at the same time as this reset, closes and returns to its original state. [0039] By resetting the flip-flop 46a described above, Q
The shift register 48a whose output is inverted and used as a reset input is reset, and all bits become 0 or low level. As a result, the shift register 48a also returns to its initial state, so the artist magnets 17a and 17b are demagnetized and the special game ends. [0040] Note that the timer 52a is used for a certain period of time during which the special game continues.
The operating time of each circuit (shift time, etc.) is added to the set time (30 seconds) of the timer, but since the operating time of each circuit is negligible compared to the set time of the timer, It is recognized that the excitation time (the fixed time during which the special game continues) is determined by the timer 52a. Furthermore, instead of continuously exciting the electromagnets 17a and 17b for a certain period of time, they may be excited intermittently. [0041] As described above, when the detectors 10a to 10c are turned on, the decimal counts 37a to 37c are stopped by operating the stop switch 12 or counting up the timer 40, and the output numbers are all set to "7" (that is, 1- 2-4 weight is "1", weight 8 output is "0") Both electromagnets 17a, 17
b is excited and demagnetized after 30 seconds, that is, one cycle of one special game can be understood in detail. [0042] However, during the continuation of this circular motion, the batted ball that entered the opening 14 enters the continuation port 28, flows down the special flow path 29, and turns on the special switch 30, which is a component of the continuation condition determination means. When this happens, both electromagnets 17a and 17b are excited again for 30 seconds, so the special game is repeated. [0043] That is, the AN that is solely responsible for the output of the special switch 30
The output of the D gate 54 is supplied with the Q output of the flip-flop 46a before being reset by the timer 52a. Therefore, when the special switch 30 is turned on during the excitation of both electromagnets 17a and 17b, the AND gate 54 is opened and the flip-flop 55, which is a component of the continuation condition determining means, is set. This flip-flop 55 is a storage circuit until information about the next electromagnet excitation operation arrives, and then sends a signal for exciting both electromagnets 17a and 17b as a high level Q output to the AND gate 56. I have them on standby. [0044] Then, when the fourth special game ends after a certain period of time (30 seconds) has elapsed, the front vibrator circuit 57 emits one pulse, and this pulse is applied to the AND gate 56. Therefore, the AND gate 56 performs an AND operation with the high level Q output of the flip-flop 55 which is already on standby as described above, and then performs an AND operation via the OR gate 44.
A high level signal is sent to 45a alone. [00453 If this happens, the same operation as the first output 42a of the discrimination circuit 41 explained earlier will start, so both electromagnets 17a and 17b will be energized for the time set by the timer 52a and the special game will start. is repeated. [0046] The output of the OR gate 44 resets the flip-flop 55 via another OR gate 58, and the reset flip-flop 55 is activated when the special switch 30 is turned on during a repeated special game. You will remember the signal at the time. If the special condition is not achieved, there is no signal from the special switch 30, so the entire circuit returns to its original state after the special game ends, and if there is a signal from the special switch 3o, the special game is repeated again. It will be. In other words, the excitation operation of both electromagnets 17a and 17b that continues for a certain period of time (30 seconds) constitutes one basic unit, that is, one cycle. [0047] Also, the number of repetitions of the special game is kept constant (
For example, in order to limit the number of times (10 times), the following circuit configuration is added. [0048] That is, an N-ary counter 59 is used as a counting means, for example, by setting N=10 to make it a decimal counter, and a carry signal (carry signal) of the counter 59 is used to trigger the OR gate 58.
The flip-flop 55, which serves as a special switch signal storage circuit, is reset through the circuit. The N-ary counter 59 counts the basic unit of the first special game as one cycle, and counts this cycle ten times. [0049] Therefore, since the carry signal from the counter 59 is not output until the 9th cycle, every time there is an output from the special switch 30 in each cycle, the flip-flop 55 which is a memory circuit is
stores this information and moves to the next cycle after the cycle ends. [00501 However, when the 10th cycle is reached, the N-ary counter 59
continues to issue a carry signal to keep the reset input of the flip-flop 55 at a high level, even if there is an output from the special switch 30 during that time, the flip-flop 55
The Q output of is pulled to a low level. Therefore, in the 10th cycle, even if there is an output from the special switch 30, that is, even if the continuation condition is achieved, it is equivalent to no output from the special switch 30, and the cycle does not proceed to the 11th cycle. [0051] In order to cause such an operation, the N-ary (decimal)
The counter 59 requires the following conditions. That is, the count must be reset before the first time the special game starts, and the count must be incremented by "1" every cycle. Such conditions can be easily set by a person skilled in the art by constructing arbitrary logic, but in the embodiment shown in the drawings, processing is performed as follows. [0052] First, the counter is reset using the first output 42a of the discrimination circuit 41, which is the starting condition for the first special game,
In addition, the repeat count of the special game is the electromagnet 17a, 17
The time-up signal of the timer 52a (signal to the AND gate 53a), which is activated after the timer 52b is excited, is input to the counter. [0053] Therefore, before the start of the first cycle of the special game, the decimal counter 59 is reset by the first output 42a, the special game is repeated for 10 cycles, and the signal from the timer 52a becomes 1.
If it is given 0 times, a carry signal is generated and the flip-flop 55 is reset, so that the special game in the 11th cycle is not played. [0054] In addition, when a batted ball enters the specific hole 31 during a special game and is detected by the stop switch 60 as a component of the end condition determining means, and the end condition is achieved, the stop switch 60 An output is given to AND gate 61. A
Since the ND gate 61 uses the Q output of the flip-flop 46a as a single source, when it receives the output from the stop switch 60 during the special game, the Q output of the flip-flop 46a
It is ANDed with the output, and this AND output sets the flip-flop 62. When the flip-flop 62 is set, the output of the AND gate 63 goes to a high level, and if a high level output is received from the timer 52a after a certain period of time while the special game continues, an AND is obtained, and this AND output is sent to the OR gate. 58 to reset the flip-flop 55. When the flip-flop 55 is reset, the special game ends in the cycle without energizing the electromagnets 17a and 17b as described above. [0055] Note that the flip-flop 62 is similar to the other flip-flop 4.
Since it is set by the AND output of the Q output of 6a and the abort switch 60, it can be set only during a special game where the Q output is at a high level. Further, the end condition may be a condition that is achieved in relation to a batted ball flowing down in the gaming section 7 flowing into a specific area, for example, a winning batted ball that enters the special variable winning device 13 during a game. If the number reaches a predetermined number, the end condition may be considered to have been achieved, and the special game may be ended in that cycle. [0056] On the other hand, for convenience during maintenance and inspection, a monitor switch 64 is provided on the back of the pachinko machine 1 in this embodiment, and when operated, each of the decimal counters 37a to 37
The output of this switch is put into the preset input of each decimal counter so that all digits c are sent to the decimal number "7". However, the flip-flops 34a to 34c, which operate the counters 37a to 37c when the detectors 10a to 10c' are turned on, are connected to the preset input from the monitor switch 64 so that this monitoring is possible only when they are all in the reset state. AND gates 65a to 65C are provided in the signal lines for performing an AND operation with the inverted Q outputs of the corresponding flip-flops 34a to 34c. [0057] Up to this explanation, the first output 42a is transmitted from the discrimination circuit 41 in the case where a specific condition is achieved by hitting the ball and there is a separate game, and in this separate game, the specific condition is achieved and a special game occurs. This makes everything work.

Next, if the specific condition is not achieved in another game and the first profit game occurs, that is, each decimal counter 37a to 37
The case where the decimal values of only the counters 37c and 37b of c are aligned and the discrimination circuit 41 issues the second output 42b will be explained. [0059] In this case, the profit level for the player is much lower than that of the special game, and the second output 42b and the flip-flop 34a, which have been reset as described above, are
The AND gate 43b performs an AND operation with the inverted Q output of the AND gate 43b, and this AND output is given to the output of another AND game 45b. Since the supply input of this gate 45b receives the inverted Q output of the flip-flop 46b which uses this gate output as the set input, the AND game 45b will also be opened, and the flip-flop 46b will be set and the Q output will be set. Output becomes high level. At the same time, the inverted Q output becomes low level, and the AND gate 45b is closed. [0060] On the other hand, the high level signal of the Q output from the set of flip-flops 46b is sent to one non-inverting input of a three-input AND gate 47b having a -inverting input, and the inverting input is clocked by the output of this gate 47b. The most significant bit output of the shift register 48b, which has a 4-bit parallel output terminal, is received, and since this output is at a low level, each time the output of the oscillator 49 enters the remaining non-inverting input, an AND is performed. The gate 47b passes this, and therefore the shift register 48b sequentially sets the parallel bit output from "1" to high level from the LSB to the MSB. As a result, first, the auxiliary electromagnet 25a is excited via the driver 51a, then the electromagnet 17a is excited via the ○R agate 0a and the driver 51b, and then the electromagnet 17b is excited via the OR gate 50b and the driver 51c. , the electromagnet 25b is finally excited. [0061] Then, when the shift register 48b subsequently sets the MSB output to "1", this output closes the AND game 47b, and the output of the oscillator 49 is no longer given to this register 48b, so each electromagnet 25a, 17a, 17b,
25b is continuously excited. [0062] This state is the mode of the first profit game, and each electromagnet 25
a, 17a, 17b. When 25b is excited, the guide pieces 15a and 1 are energized as described above.
5b is located at the lower side of the opening 14, and the auxiliary guide pieces 16a, 16b are located at the left and right sides of the opening 14. Therefore, when a hit ball flowing down the gaming section 7 reaches the opening 14, it is guided by one of the guide pieces 15a, 15b and enters the inside, becoming a safe ball, so that the probability of the hit ball winning a prize increases. [0063] The first profit game described above does not continue indefinitely, but only for the set time of the timer 52b. This timer 52b starts operating with the MSB output of the shift register 48b, and when the set time (for example, 15 seconds) has elapsed, the AND gate 53b performs an AND operation with the Q output of the flip-flop 46b that has been set. AND game)
53b returns the flip-flop 46b to its initial state, and at the same time, the low-level Q output is applied to the reset input of the shift register 48b having an inverted reset input via the OR gate 66a.
All electromagnets 25a, 17a, whose b is reset
17b and 25b are demagnetized [0064] Therefore, the first profit game lasts only 15 seconds, for example, set by the timer 52b, and there is no repeat function like the special game described above, and when it ends, the first profit game 2 outputs 4
Return to the initial state with 2b. [0065] In addition, the structure of the code|symbol which attached the number rbJ in the circuit of the 1st profit game is the same as the structure of the circuit in the previous special game. [0066] On the other hand, if the player's batted ball achieves the first condition in the gaming section but does not achieve anything in another game and the discrimination circuit 41 issues the third output 42c, it is considered as a second profit game. J Kai 13-db611d('tLP)ru. This second profit game has even fewer profit states for the player than the first profit game, and the circuit configuration of this second profit game is almost the same as the circuit configuration of the first profit game, as is clear from the block diagram. . [0067] To explain the electrical processing mode of this second profit game, the third output 42c and the inverted Q output of the flip-flop 34a are ANDed by the AND gate 43c, and this AND output is sent to the other AND gate 45C. given to the power of one person. This AND gate 45c is open because its other input receives the inverted Q output of the flip-flop 46c.
The flip-flop 46c is set and the Q output becomes high level. The high level signal of this Q output is sent to one non-inverting input of a three-input AND gate (47c) having one inverting input, and the inverting input is a shift register with a 4-bit parallel output terminal that receives the output of this gate 47C as a clock. Since this output is at a low level, the AND gate 47c passes it every time the output of the oscillator 49 is input to the other non-inverting input, and therefore the shift register 48c receives the output from the LSB. The parallel bit output is sequentially set from "1" to high level toward the MSB. [0068] As a result, first, the OR gate 50a and the driver 51b
The electromagnet 17a is excited via the
, the electromagnet 17b is excited via the driver 51c, and then when the MSB output is set to "1", the AND game 47c is closed by this output, and the oscillator 4
Since the output of No. 9 is no longer given to the shift register 48c, both electromagnets 17a and 17b are continuously excited. This state is the mode of the second profit game, and both electromagnets 17a, 1
Both guide pieces 15a and 1 are attached to the lower side of the opening 14 by the excitation of 7b.
5b is located, and a part of the ball hits both guide pieces 15a, 15b.
This causes the ball to flow into the opening 14 and become a winning ball. [0069] Therefore, in the second profit game, the guide piece 15a is activated by excitation of the electromagnets 17a and 17b. 15b is located at the lower side of the opening 14 to receive the batted ball flowing down the gaming section, and continues for the time set by the timer 52c (for example, 5 seconds). The timer 52C, like the timer 52b, operates on the MSB output side of the shift register 48c, and when the time is up after 5 seconds have elapsed, an AND game 53c performs an AND operation with the Q output of the flip-flop 46c, which is set. The flip-flop 46c is reset by the output of the gate 53c to return to the initial state, and the low-level Q output is applied to the reset input of the shift register 48c via the OR gate 66c, thereby resetting the shift register 48c. The artist magnets 17a and 17b are demagnetized. [00701] Therefore, the second profit game continues for, for example, 5 seconds set by the timer 52c, and like the first profit game, there is no repeat function. [0071] Also in the second profit game, the configuration of the symbol with the number "c" is the same as the circuit configuration in the special game. [0072] Also, in the circuits for the first profit game and the second profit game, ○ is inserted in the reset signal lines to the shift registers 48b and 48c.
R game) 66a, 66b, the OR gate 66a,
66b is connected to the reset signal line to the shift register 48a for the special game, even when the circuit system is operating due to the first profit game or the second profit game, at the same time as the reset of the special game, all The purpose is to demagnetize the electromagnet. [0073] Next, a case will be described in which the probability of occurrence of a special game is electrically adjusted. Now, assuming that the outputs of the three decimal counters 37a to 37c are not tampered with, the probability that they will match is 1/10, that is, 1.
It is 1 in 1,000, and the specific condition is achieved only 1 out of 1,000 times in another game. Considering the state of the weighted bits of each decimal counter in this case,
The weight 8 is '0111.' As shown by the connection line 67a, if the output of is pulled up to the power supply potential +Vcc and fixed at "1", the remaining 8-4-2 bits become "'011" and the value becomes the decimal number "7J (0111)". Outside of “6J”
(0110). That is, actually the counter 37a
Even if ``6'' is output, the counter 37a outputs ``7''.In the end, when ``7'' outputs ``6'', this counter 37a outputs ``7''.
can be considered to be outputting. Therefore, the probability that this counter 37a outputs "7" is 1/5, compared to 1/10 of the other counters 37b and 37c. Therefore, the probability that all the counters 37a to 37c are 7 is 115xl/10xl/10=11500
Therefore, the probability of special games occurring increases. therefore,
The connection line 67a functions as a target profit rate setting operation means. [0075] In exactly the same way, the LSB of the two decimal counters 37a and 37b is connected to the connecting line 67b as a target profit rate setting operation means.
If you pull it up to the power supply potential +Vcc and fix it to "1", the probability that each counter will have "7" is 115X115X
1/10 = 1/250, which is 1/250, and each counter 37a to 37c is connected to LS via the connection line 67c.
If you pull up B, 115xl 15xl 15=1
/125, and the specific condition is achieved only once out of 125 times in another game. Then, when the connection lines 67a to 67c functioning as target profit rate setting operation means are operated from outside to set the target profit rate that can be given to the player based on the result of another game, A
ND gates 35a to 35c, oscillators 36a to 36c
, the counters 37a to 37c function as special condition achievement probability control means, and can cause another gaming means to achieve the special condition at a frequency based on the target profit rate set by the connection line. [0076] Of course, this probability adjustment can be done on either bit output, and instead of pulling up to the supply voltage, either bit can be pulled down to ground potential, i.e., the binary "0" This can also be done by fixing it to ``. [0077] The electrical operations of the special game, the first profit game, and the second profit game described above are just one example, and the circuits can be designed freely by other electronic means that can be considered. [0078] The design of the present invention can be changed in any state as long as it complies with the description of the claims. For example, as described above, the circuit may be changed appropriately, or the number of decimal counters may be changed. or the number of electromagnets so that only the special game can be played, or the special game and either or both of the first profit game and the second profit game can be selectively performed. [0079] Further, the specific hole 31 is not limited to the above embodiment. For example, another embodiment of the specific hole 31 shown in FIG.
This is a so-called tulip type in which the movable piece 69 changes to a state where it can easily receive a batted ball as shown on the right side of the figure. When the specific conditions are met and the special game starts, the solenoid 68 is energized by the first output 42b as shown in FIG. 5, and the movable pieces 69 and 69 change the state into a state where it is easy to receive the ball. [0080] The player fires a batted ball while being careful not to let the batted ball enter the specific hole 31. However, if the batted ball unfortunately lands on the movable piece 69 and enters the specific hole 31, the stop switch 60 detects the batted ball. to end the special game in that cycle. [0081] Note that when the solenoid 68 is demagnetized and the movable piece 69 is closed, the obstacle piece 70 located above the movable piece 69 prevents the ball from being hit so that the end condition is not satisfied. [0082] Another embodiment of the specific hole 31 shown in FIG. 31 is configured to have a narrow width. If a batted ball enters the opening 14 during the special game and enters the continuation hole 28, the special switch 30 is turned on and the special game can be repeated. However, if the batted ball enters the specific hole 31. , the cancel switch 60 is turned on, and the special game ends in this cycle. For this reason, players play special games with a mixture of expectations and anxiety, and the interest in pachinko games increases significantly [0083]
