Abstract

(57) [Abstract] [Purpose] To provide a variable winning device in which the open state and the continuation condition thereof are not dependent on the difference in the skill of the player. [Structure] The winning ball from the special winning opening 92 is received by the baffle plate 42 and then dropped from the falling opening 36 to the ball guiding mechanism 52. The position where the ball guide mechanism 52 is dropped does not depend on the arrangement of nails near the special winning opening 92 or the like. The probability that the ball guide mechanism 52 passes through the special drop opening 58 is not affected by the arrangement of the nails near the special winning openings 92, 92, or the like. For this reason, it is avoided that the probability of continuation of the open state is affected by the arrangement of nails in the vicinity of the special winning opening 92, which is advantageous for the player who is excellent in the ability to discriminate such an environment, and for those who are not so. Since the disadvantage is eliminated, the fairness of pachinko games is further improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a variable winning device for a pachinko machine.

[0002]

[Prior art]

 As is well known, some pachinko machines are equipped with a variable winning device that switches between a state where the winning probability is high and a state where the winning probability is low depending on whether or not a preset condition is satisfied.

As an example of such a variable winning apparatus, there is a variable winning apparatus called a first-class special electric accessory. As shown in FIG. 10, this type of variable winning device 300 determines whether a special game condition is satisfied by a calculation process each time a start winning hole is won, and when this condition is satisfied (big hit), a variable symbol display device A special symbol representing a hit such as 777 is displayed on 302, and the special winning opening 306 is opened by tilting the ball receiving plate 304 forward to create a gaming state in which the winning probability is extremely high. In the open state in which the special winning opening 306 is opened in the variable winning device 300, for example, when 30 seconds elapses or when there are 10 winning balls in the big winning opening 306, the big winning opening 306 is displayed on the ball receiving plate 304. Although it ends once by being closed, immediately after the predetermined continuation condition is satisfied, the special winning opening 306 is opened and the opened state is restarted. In other words, the open state will be continued when the continuation condition is satisfied. As shown in FIG. 11, the continuation condition in the variable winning device 300 is established when the winning ball passes through the special area 308 provided inside the special winning opening 306, and the passing condition of the winning ball special area 308 is satisfied. The probability is set to be about 1/3, for example.

However, the passage of the game ball through the special area 308 is greatly affected by the processing accuracy inside the special winning opening 306, the collision state of the gaming ball with the nail immediately before reaching the special winning opening 306, and the like. Specifically, if the arrangement of the nails near the special winning opening 306 is suitable, the winning ball to the special winning opening 306 can easily pass through the special area 308, and as a result, the open state can be easily maintained. . This is advantageous for a player who is excellent in the ability to determine the environment around the special winning opening 306 such as placement of nails, is disadvantageous for a player who is not so, and has a problem in the fairness of pachinko games. I was there.

Further, as shown in FIG. 12, there is known a variable winning a prize device 408 called a second type special electric auditors product that operates by winning a specific start winning hole 402, 404, 406. As shown in an enlarged scale in FIG. 13, the variable winning device 408 is preset when the start winning opening 402 to 406 is won and the pair of opening / closing members 410 are oscillated as shown by broken lines. The special winning opening 412 is opened for an opening time, for example, 0.5 seconds.

If the winning ball that has won the special winning opening 412 within the opening time of 0.5 seconds passes through the special area 420, the special winning opening 412 is opened and the winning probability is extremely high. Is created. On the other hand, if none of the winning balls within the opening time passes through the normal area 422 without passing through the special area 420, the open state is not created and until the start winning holes 402 to 406 are won again. The normal game state is continued.

The passing probability of the special area 420 is set to about 1/10, and as shown in, for example, FIGS. 13 and 14, inside the special winning opening 412, there is an inclination from the front to the back. An inclined plate 414 is provided, and the winning ball moves on the upper inclined plate 414 to the inner side and drops from two notches 416. The dropped winning balls move on the lower sloping plate 418 that inclines from the back to the front and pass either the special area 420 or the normal area 422. However, as is apparent from the drawing, a guide groove 424 is provided in the central portion of the downward swash plate 418, and the winning ball needs to be guided to the guide groove 424 in order to pass through the special area 420. There is. With such a configuration, the passing probability of the special area 420 is set to about 1/10. In addition, as shown in FIG. 13, the winning balls that have passed through the special area 420 pass through the proximity switch 426, merge with the winning balls that have passed through the ordinary area 422, and are discharged through the proximity switch 428.

The open state of the variable winning device 408 is such that, for example, 30 seconds have elapsed or 10 balls have entered the special winning opening 412 when the opening / closing member 410 repeats opening / closing at predetermined intervals, for example, at intervals of 0.5 seconds. When there is a winning ball, the opening / closing member 410 is closed, and the open state is temporarily terminated. However, if the winning ball passes through the special area 420 during the open state, it is determined that the continuation condition is satisfied, and the open state is restarted immediately thereafter.

As described above, the probability of passing the special area 420 of the winning ball is set to be about 1/10, and the continuation condition in the above-described variable winning device 300 (first-class special electric auditors). It is lower than the probability of success. That is, even if there is an opening of the special winning opening 412 due to the winning of the starting winning openings 402 to 406, the probability of being in an open state is low. However, if the number of winnings in the start winning holes 402 to 406 is large for 0.5 seconds when the special winning opening 412 is opened, it is relatively easy to reach the open state. The skill to win the prize in good timing is required depending on the condition of the nails around 412. That is, it is advantageous for the player who is excellent in the ability to determine the environment around the special winning opening 412 such as placement of nails, and is disadvantageous for the player who is not so. Further, since the probability of continuation of the open state is low, it can be said that the open state is small despite the frequent opening of the special winning opening 412.

However, in the variable winning device 408, as is clear from its structure, the probability that the continuation condition is satisfied is not easily affected by the arrangement of nails near the special winning opening 412.

[0011]

[Problems to be solved by the device]

 As described above, the conventional variable winning device, the first-class special electric auditors product, and the second-class special electric auditors product each have advantages and disadvantages, and a variable winning device having a configuration different from these has been demanded.

The present invention provides a probability that a continuation condition that depends on the skill of the player will be satisfied in the first-class special electric auditors and an open state that depends on the skill of the player in the second-class special electric auditors. It is intended to provide a new variable winning device in which the establishment and the probability of its continuation are low.

[0013]

[Means for Solving the Problems]

 As means for solving the above-mentioned problems, the variable winning device according to claim 1 is a variable winning device mounted on a pachinko machine and changing a winning probability depending on whether a preset condition is satisfied or not, Symbol display means capable of displaying a plurality of types of symbols, random number calculation means for calculating random numbers, starting signal output means for detecting a winning at the starting winning opening and outputting a starting signal, and due to the input of the starting signal Determination means for determining the hit by collating the randomly selected random number with a preset hit value, and display control for displaying a hit symbol on the display means when the hit is judged by the decision means Means, a pair of swinging blades that are swingably displaced between an upright position and a fall position about an axis substantially vertical to the board surface of the game board, and the swinging blades in the upright position close the winning probability When the swinging blade is in the laid-down position, a variable winning opening that is opened to increase the winning probability, a winning ball sensor that detects a winning ball to the variable winning opening and outputs a count signal, and based on the counting signal Counting means for counting winning balls to the variable winning a prize, and when the determining means determines a hit, the pair of swinging blades are continuously or repeatedly laid down to win the variable winning a prize. The open state with a high probability is set, and when the set opening time elapses or when the number of winning balls to the variable winning opening in the open state reaches the set number, the swinging blade is set to the standing position and the open state is ended. Means, a baffle that guides the winning ball to the variable winning opening to the falling opening, and a continuation condition judging means for judging the establishment of the continuation condition based on the timing of dropping the game ball from the falling opening or the route after the falling. And the continuation clause When the case determination means determines that the continuation condition is satisfied, the opening means is provided with continuation instructing means for instructing resumption immediately after the opening state is ended.

According to a second aspect of the present invention, there is provided the variable winning device according to the first aspect, further comprising a ball guiding mechanism that guides the winning balls dropped from the drop opening to a special area at a predetermined rate. The continuation condition determining means is configured to determine that the continuation condition is satisfied if any of the winning balls in the open state passes through the special area.

According to a third aspect of the present invention, there is provided the variable winning device according to the first or second aspect, wherein the dropping port is provided at one location and the winning ball sensor is installed at the dropping port. . It is characterized in that display means is provided for changing the display state when it is determined that one of the winning balls in the open state is hit.

[0016]

[Action]

 In the variable winning device according to claim 1 having the above-mentioned configuration, the symbol display means can display a plurality of types of symbols. The random number calculation means calculates a random number. The starting signal output means detects a winning in the starting winning opening and outputs a starting signal. The determination means compares the random number selected due to the input of the start signal with a preset hit value to determine a hit. The display control means causes the display means to display the hit symbol when the decision means determines that the hit is successful. The pair of oscillating blades are oscillatingly displaced between an upright position and a fallen position around an axis substantially vertical to the board surface of the game board. The variable winning opening is closed by the swinging blades in the upright position to reduce the winning probability, and when the swinging blade is in the lying position, it is opened to increase the winning probability. The winning ball sensor detects a winning ball to the variable winning opening and outputs a counting signal. The counting means counts the winning balls to the variable winning port based on the counting signal. When the determination means determines that the win is successful, the pair of swinging blades are continuously or repeatedly laid down to make the variable winning opening into an open state with a high winning probability, and the set open time has elapsed or has been released. When the number of winning balls to the variable winning port reaches the set number, the swinging blade is set to the standing position and the open state is ended. The baffle guides the winning ball to the variable winning port to the falling port. The continuation condition determination means determines whether or not the continuation condition is satisfied, based on the timing of the game ball falling from the drop opening or the route after the drop. When the continuation condition determination means determines that the continuation condition is satisfied, the continuation instruction means instructs the opening means to resume the operation immediately after the opening state is ended.

When it is determined that the winning is determined by the determining means, the player is informed that the winning pattern is displayed by the display of the winning symbol on the display means, and the variable winning opening is opened. No prizes are required to be awarded to the variable prize device when starting the open state. For this reason, it is not necessary to have a skill to win the prize in a timely manner depending on the state of the variable winning opening, which is advantageous for a player who has an excellent ability to determine the environment around the variable winning opening such as the arrangement of nails, and for those who do not Is not at a disadvantage.

This open state is temporarily terminated when the set time elapses or the set number of winnings are reached, but if it is determined that the continuation condition is satisfied for any of the winning balls in the open state, the open state is temporarily terminated. Immediately after it is restarted. The winning ball is once guided to the drop port by the baffle, and the continuation condition is determined by the timing of the drop from the drop port or the route after the drop, but the timing of the drop from the drop port and the subsequent route are However, it is not affected by the arrangement of nails near the variable winning device, especially near the variable winning opening. Therefore, the probability of establishment of the continuation condition is not influenced by the skill of the player who determines the environment around the large variation winning opening such as the arrangement of nails. It also eliminates the dissatisfaction that the open state is established and the probability of its continuation is too low compared to the frequency of the swinging blades.

In the variable winning device according to the second aspect, if any of the winning balls in the open state passes through the special area, the open state is restarted immediately after the open state is ended. Since the continuation of the open state is determined by the passage or non-passage of the special area, the configuration can be simplified and the effect of the configuration of claim 1 can be further ensured. Further, if the player can visually recognize the passage of the winning ball through the special area, the reliability of the player can be improved.

Next, in the variable winning device according to claim 3, since there is only one drop port and a prize ball sensor is installed at this drop port, the prize ball is first detected by the prize ball sensor. After being hit, it falls to the ball guide mechanism. For this reason, the time lag from the passage of the variable winning award winning ball to the output of the counting signal is shortened, so that it is less likely that more than the set number of award winning balls will be generated in one open state.

A special winning sensor 62 including 60 is installed. This special prize sensor 62 is a well-known proximity switch, and when a game ball passes through the passage opening 60, it detects this and outputs a special prize signal. Further, a separating plate 64 is erected on the inclined portion 56b so as to face the side plate 54b, and divides the inclined portion 56b into a special drop port side 66 and a normal side 68.

As shown in FIG. 4, a distribution member 70 is installed inside the frame member 54 along the back plate 54a. The distribution member 70 includes a pair of side plates 72a and 72b facing each other, and is divided into a special part 76 and a normal part 78 by a partition plate 74 provided between the side plates 72a and 72b. Further, the bottoms 80 and 82 of both the special portion 76 and the ordinary portion 78 are inclined in a direction in which they are higher near the partition plate 74 and lower as the distance from the partition plate 74 increases.

The display panel 96 has three types of numbers. The symbols and symbols can be displayed in a horizontal row. Further, the upper box member 86 is provided with four memory display lamps 98 along the upper side of the display panel 96, and a V lamp 100 larger than these is mounted above the memory display lamps 98. . The memory indicator lamp 98 and the V lamp 100 are LEDs. Further, a top winning port 102 is provided on the top of the upper box member 86. The winning ball to the top winning port 102 is discharged to the back side of the game board 14 through the passage formed in the mechanism accommodating portion 30.

As shown in FIG. 5, starter sensors 110, 110, 110 are connected to a control unit 106 incorporated in the control board 104 of the pachinko machine 12 via an input interface 108, and a start winning opening When any one of 16, 18, 20 wins, the start signal SS output from the start sensors 110, 110, 110 is input to the control unit 106. Similarly, the input interface 108 is connected to the winning sensor 50 and the special winning sensor 62 provided in the variable winning device 10, and the winning signal SI from the winning sensor 50 and the special winning sensor 62 from the special winning sensor 62 are connected. The award signal SP is input to the control unit 106.

The control unit 106 has a well-known CPU, ROM, RAM, etc., and is configured as an arithmetic circuit capable of executing various arithmetic processes according to a program stored in the ROM in advance. A timer circuit 112 and a counter 113 are connected to the control unit 106, and the control unit 106 can read the count values of the timer circuit 112 and the counter 113. Further, swinging solenoids 114, 114 for opening and closing the swinging blades 88, 88 are connected to the control unit 106 via drive circuits 116, 116, and a swinging solenoid is generated by a signal from the control unit 106. By operating 114, 114, it is possible to control the fall and rise of the swinging blades 88, 88, that is, the opening and closing of the special winning openings 92 1, 92. Similarly, a reciprocating drive mechanism 118 is connected to the control unit 106 via a drive circuit 117, and the reciprocating drive mechanism 118 is operated or stopped by a signal from the control unit 106 to reciprocate the distribution member 70. Can be controlled.

A memory indicator lamp 98 is connected to the control unit 106 via a drive circuit 119, and the memory indicator lamp 98 can be made to blink one by one in response to a signal from the controller 106. Similarly, the V lamp 100 is connected to the control unit 106 via the drive circuit 120, and the V lamp 100 can be blinked in response to a signal from the control unit 106. Further, a display panel 96 is connected to the control unit 106 via a drive circuit 122, and a three-digit number or symbol can be displayed on the display panel 96 according to a signal from the control unit 106.

It should be noted that the control unit 106 receives signals from a proximity switch or the like installed in the top winning opening 102 or another ordinary winning opening 22 provided in the game board 14, and receives a prize ball paying device, It is a configuration that can control the operation of solenoids and motors of various types of equipment, blinking of lamps, and various audio outputs.

Next, the operation of the variable winning apparatus 10 will be described together with the variable winning control executed by the control unit 106. Prior to this, the count routine executed by the counter 113 will be described. This counting routine is continuously executed while the pachinko machine 12 is operating.

As shown in FIG. 6, when the power of the pachinko machine 12 is turned on and the count routine is started, the counter 113 sets the count value N to 0 (step 1100). Then, it is determined whether or not there is an output request from the control unit 106 (step 1200). If it is determined in step 1200 that there is an output request, the counter 113 proceeds to step 1300 and outputs N to the control unit 106. When it is determined in step 1200 that there is no output request and after the processing of step 1300 is performed, the counter 113 determines N = 249 (step 1400). If N = 249, the counter 113 returns to step 1100 and repeats the above processing. On the other hand, if N ≠ 249, the counter 113 increments N and returns to step 1200. That is, the counter 113 repeats counting from 0 to 249 as N, and outputs the count value N every time there is a request from the control unit 106. Further, the ROM of the control unit 106 stores in advance a display numerical value table in which the count value N and the 3-digit display numerical value N2 are associated with each other, and the control unit 106 controls the display numerical value N 2 based on the count value N 2. Can read N2.

Next, the variable winning control routine executed by the control unit 106 will be described. It should be noted that this variable winning control routine is repeatedly executed during the operation of the pachinko machine by a time interrupt at a preset timing. As shown in FIG. 7, the control unit 106 that has started the variable winning control routine (hereinafter, also referred to as a main routine) determines whether or not there is a start signal SS from the start sensor 110 (step 2100). If the start signal SS is input here, the process proceeds to the next step 2200, and if No, the main routine is once ended.

In step 2200, the control unit 106 requests the counter 113 to output the count value N and reads the count value N. Subsequently, the control unit 106 determines whether or not the count value N matches the preset hit value A. If N ≠ A, the control unit 106 causes the display numerical value N2 (outlier numerical value) read from the display numerical value table based on the count value N to be displayed on the display panel 96 (step 2400), and the main routine To finish. On the other hand, if N = A, the control unit 106 causes the display panel 96 to display the display value N2 (a hit value, for example, 777) read from the display value table based on the count value N (step 2500). . Here, the count value N is determined by the input of the start signal SS from the start sensor 110, that is, the timing of winning the start winning holes 16, 18, 20. Since the timing of winning at the starting winning openings 16, 18, and 20 cannot be predicted, the count value N used in the processing in the control unit 106 is determined at an unpredictable timing. The count value N output to the control unit 106 is actually a random number.

Next, the control unit 106 executes a continuation control subroutine in step 2600. As shown in FIG. 8, when the continuous control subroutine is started, the control unit 106 resets the number of balls entered CI, the number of openings CC and the hit flag F to 0 (step 3100). Subsequently, the control unit 106 operates the reciprocating drive mechanism 118 to reciprocate the distribution member 70 (step 3200).

Next, the control unit 106 energizes the swinging solenoids 114 and 114 by the output of the solenoid drive signal, and causes the swinging blades 88 and 88 to lie down to open the special winning openings 92 and 92 (step 3300). ). Therefore, the variable winning apparatus 10 is in an open state with a high winning probability. The output of the solenoid drive signal is continued until a stop condition described later is satisfied.

Next, the control unit 106 increments the opening count CC (step 3400). The number corresponding to the number of times of opening CC is displayed on a number-of-times display panel (not shown) so that the player can recognize the number of times of opening. Next, the control unit 106 determines whether or not there is a winning signal SI from the winning sensor 50 (step 3500). If the winning signal SI is input here, the number of winning balls CI representing the number of winning balls to the special winning openings 92, 92 is incremented in the next step 3600. Subsequently, the control unit 106 determines whether the CI has reached 10, that is, whether or not the winnings in the special winning openings 92, 92 have reached 10 balls (step 3700). If CI is 10 or less, the process proceeds to step 3800, and it is determined whether or not there is the special winning signal SP from the special winning sensor 62. If there is the special winning signal SP here, the control unit 106 proceeds to step 3900 to determine whether or not the hit flag F = 1. If F ≠ 1, the control unit 106 proceeds to step 4000 and sets the hit flag F to 1. Subsequently, the control unit 106 turns on the V lamp 100 (step 4100). By turning on the V lamp 100, it is possible to inform the player that the game ball has passed through the special drop opening 58. After this step 4100 or when it is determined that F = 1 in step 3900, the control unit 106 proceeds to step 4200.

In the next step 4200, the control unit 106 determines whether CI = 10. If CI ≠ 10, that is, if it is determined that the current winning ball is not the tenth ball, the control unit 106 proceeds to step 4300. Also, when it is determined in step 3500 described above that the winning signal S I is not input, the control unit 106 proceeds to step 4300. In step 4300, the control unit 106 determines, based on the output of the timer circuit 112, whether 30 seconds have elapsed from the start of the open state. If it is determined that 30 seconds have not elapsed, the control unit 106 returns to step 3500 and repeats the above processing.

On the other hand, if it is determined in step 4300 that 30 seconds have elapsed, the control unit 106 proceeds to step 4400 shown in FIG. Further, also when it is determined in the above-described step 3700 that the number C I of incoming balls exceeds 10 and when it is determined in step 4200 that the number C I of incoming balls is 10, the control unit 106 proceeds to step 4400.

As shown in FIG. 9, in step 4400, the control unit 106 temporarily stops the output of the solenoid drive signal to stop the energization of the swinging solenoids 114, 114, thereby causing the swinging blades 88, 88 to move. It stands up and closes the special winning openings 92, 92. As a result, the variable winning device 10 temporarily ends the open state. In other words, the open state is terminated when the number of winning balls is 10 or more or 30 seconds have passed after the start of the open state. However, for the tenth winning ball, steps 3800 to 4100 are executed and then the open state is ended.

Subsequently, the control unit 106 determines whether the opening count CC has reached 16 (step 4500). If the number of releases is 16 or more, the control unit 106 returns from this subroutine and ends the variable winning control routine. If CC is less than 16, the control unit 106 proceeds to step 4600 and determines whether the flag F = 1 or not, that is, whether there is a game ball that has passed through the special drop opening 58 in the above-mentioned open state. . If the hit flag F ≠ 1, the control unit 106 returns from the continuous control routine to end the variable winning control routine. If F = 1, the process proceeds to the next step 4700.

In step 4700, the control unit 106 resets the hit flag F and the number of incoming balls CI to 0. Subsequently, the control unit 106 turns off the V lamp 100 (step 4800) and returns to step 3300 shown in FIG. As a result, the variable winning device 10 is opened again. That is, the open state of the variable winning device 10 is continued.

As described above, the control unit 106 opens the variable winning apparatus 10 and then wins 10 balls into the special winning openings 92, 92 (steps 3700 and 4200) or after 30 seconds (step 4300). The open state of the variable winning a prize device 10 is temporarily ended, and if any of the 10 winning balls that have won the large winning holes 92 and 92 have passed through the special drop opening 58 during this open state ( (Step 3800: YES), the open state of the variable winning a prize device 10 is continued. Moreover, if there is such a game ball (= continuation of the open state), the V lamp 100 is turned on, so that the player can recognize the continuation of the open state.

Further, in the case where no winning balls pass through the special drop opening 58 in one open state, or when the number of times of opening reaches 16 times due to the continuation of the above-mentioned open state, the open state Does not continue, and the variable winning apparatus 10 is closed. If there is a start winning a prize in the starting winning openings 16, 18, 20 in such an open state, the control unit 106 stores the number of starting winnings (up to 4 balls) and also according to the number of starting winnings. The memory display lamps 98 are turned on one by one. Further, when the continuation of the open state is completed as described above, the control unit 106 repeats the variable winning control routine until the stored starting winning number becomes zero.

As described above, whether the variable winning apparatus 10 is opened or not is determined by the counter 113 which is selected due to the winning of the starting winning opening, as in the case of the conventional first-class special electric auditors. Since it is determined based on the count value N, it does not require a skill to win the prize in a timely manner according to the state of the special winning opening 92, the nails around the 92, etc. unlike the second-class special electric accessory. Therefore, it is advantageous for the player who is excellent in the ability to determine the environment around the special winning holes 92 and 92 such as the arrangement of nails, and is not disadvantageous for the player who is not so. It will be further improved.

Further, the continuation or discontinuity of the open state is determined by a game ball that has once passed over the baffle plate 38 and dropped from the drop port 36 by the distribution member 70 and the separation plate 64 in cooperation. It depends on whether or not it passes through the special drop opening 58, but since the obstacle member as described above is interposed between the special winning openings 92, 92 and the special drop opening 58, it is a special feature of the game ball. The passing probability of the drop opening 58 is not affected by the arrangement of the nails near the special winning opening 92, 92, or the like. Therefore, unlike the conventional first-class special electric auditors, it is avoided that the probability of continuation of the open state is affected by the placement of the nails near the special winning opening 92, 92, etc. Since the advantage of the player with excellent ability and the disadvantage of the player with less ability are eliminated, the fairness of the pachinko game is further improved.

As described above, in the variable winning a prize device 10 mounted on the pachinko machine 12 of the present embodiment, the influence of the arrangement of the nails around the variable winning a prize device 10 and the like is satisfied with respect to the establishment of the conditions for starting and continuing the open state. Since it can be avoided, it is suitable for improving fairness in pachinko games.

In the above-described embodiment, the display panel 96 is the symbol display means, the counter 113 is the random number calculation means, the starting sensor 110 is the starting signal output means, and the special winning opening 92 is the variable winning opening. The winning sensor 50 corresponds to the winning ball sensor, the special drop port 58 corresponds to the special area, and the control unit 106 serves as the judging unit, the display controlling unit, the counting unit, the releasing unit, the continuation condition judging unit and the continuation instructing unit. It is functioning.

The present invention has been described above according to the embodiments. However, it goes without saying that the present invention is not limited to such embodiments and can be variously implemented without departing from the gist of the present invention. For example, in the above-mentioned example, the probability that the opening condition is satisfied by matching the counter value N with the winning number A is 1/250, but this probability is not limited to 1/250.

Further, in the open state, the oscillating blades 88, 88 are continuously laid down, but the ON-OFF control in which the laying-up is repeated at a predetermined timing as in the case of the conventional second-class special electric accessory. It is also possible to Further, in addition to the counter 113, a counter that repeatedly counts from 0 to a set value is provided, and every time there is a winning signal SI from the winning sensor 50, the count value of this counter is collated with a preset hit value. However, when the two match, it is possible to determine that the continuation condition is satisfied and to keep the variable winning device in the open state. With this configuration, the special drop port 58 and the special winning sensor 62 can be omitted.

[Effect of device]

 As described above, according to the variable winning device according to claim 1, the probability of the start of the open state or the establishment of the continuation condition is determined by the skill of the player who can determine the environment around the large variation winning opening such as the arrangement of nails. Is not affected. In addition, the dissatisfaction that the open state is established and the probability of its continuation is too low as compared with the frequency of operation of the oscillating blades is eliminated.

In the variable winning device according to the second aspect, the continuation of the open state is determined by the passage or non-passage of the special area, so that the effect of the first aspect can be further ensured with a simple configuration. Further, if the player can visually recognize the passage of the winning ball through the special area, the reliability of the player can be improved.

According to the variable winning device of claim 3, since the winning port is provided at one place and the winning ball sensor is installed in this dropping port, the winning ball is first detected by the winning ball sensor. It falls to the ball guide mechanism. For this reason, the time lag from the passage of the variable winning award winning ball to the output of the counting signal is shortened, so that it is less likely that more than the set number of award winning balls will be generated in one open state.
