The specific area entry detection switch detects a game ball that has been distributed to the specific area by the distribution device when the game ball has entered the variable winning device.

  The microprocessor mounted on the control board includes at least gaming state transition control means, ball count control means, ball history storage control means, ball sum calculation control means, and fraud notification control means. The game state transition control means distributes the game balls that have entered the variable prize device by the distribution device to a specific area, and when the specific area entry detection switch detects the distributed game balls, the game state transition control means changes from the normal game state to the player. The game has entered a special gaming state that grants profits. The ball count control means detects the game ball that has entered the variable winning device by the variable winning device incoming ball detection switch until the transition from the normal gaming state to the special gaming state that gives a profit to the player, The number of game balls detected is counted. The ball number history storage control means stores the number of game balls counted by the ball count control means as a history. For example, if the number of game balls that have entered during the transition from the normal game state to the special game state that gives the player profits is 22, the value 22 is stored as a history, and the next normal game state If the number of game balls that have entered during the period from the start to the special game state that gives a profit to the player is 51, the value 51 is stored as a history, and from the next normal game state to the player If the number of game balls that have entered during the transition to the special game state where a profit is given is 37, the value 37 is stored as a history. As a result,..., Value 22, value 51 and value 37 are stored as the history, and the latest history becomes the value 37. The total ball count calculation control means extracts each history from the latest history to a history that is back by a predetermined number based on the history stored by the number history storage control means, and stored in this extracted history The total number of game balls counted by the ball count control means is calculated. For example, if the history from the latest history to the history that is back by 10 is the value 28,..., The value 22, the value 51, and the value 37, the sum of these values is calculated. The determination control means determines whether or not the value calculated by the total ball count calculation control means is smaller than a predetermined threshold value. The cheating notification control means performs cheating notification that informs that cheating is being performed when it is determined by the judgment control means that the value calculated by the total ball count calculation control means is smaller than a predetermined threshold value. When it is determined that the value calculated by the total ball count calculation control means is not smaller than a predetermined threshold value, that is, larger, the gaming state is maintained.

  Here, for example, in the case where an illegal act of distributing all the game balls that have entered the variable winning device to a specific area is performed, there is a period of transition from the normal game state to the special game state that gives a profit to the player. Extremely short. Therefore, the number of game balls that have entered during the transition from the normal game state to the special game state is stored as a history, and based on this stored history, a history that goes back a predetermined number from the latest history And the total number of game balls stored in the extracted history is calculated, and the calculated value is compared with a predetermined threshold value so that the player can play an illegal game. It can be determined whether or not a large number of balls have been acquired. Therefore, it is possible to prevent a large amount of game balls from being acquired by a player's cheating.

A switch (specific winning opening detection switch) 52 is installed. The game ball that has entered the specific winning opening in the center accessory 6 (passed through the specific area) is detected by the specific area switch 52 and then released. The game ball that has entered the general winning opening is released as it is through the right ball discharge passage 51.

(3. Action of game balls)
Next, an operation mode (rolling / guidance / allocation etc.) of the game ball in the center accessory 6 during an actual game will be described.

(3-1. When passing through a low probability route)
FIG. 3 shows this in a three-dimensional manner in a state where each part (upper and front side) of the center accessory 6 is partially cut or broken. When the game ball that has won the big winning opening 26 is guided to the left by the ball path changing member 34, the game ball is guided through the low probability path 36 as shown by the arrow in FIG. become.

  When the game ball guided through the low probability path 36 flows down to the lower edge of the center accessory 6, it rolls across the front side of the ball sorting member 46 and wraps around the back side. When the game ball reaches a position near the terminal end of the low probability path 36, the rolling direction is influenced by the ball stopping member 44.

  FIG. 4 specifically shows the inside of the center accessory 6. A plurality (eight in this example) of U-shaped notches are formed on the periphery of the ball sorting member 46 at equal intervals in the circumferential direction. Each of these cutouts can accept one game ball, one of which is a specific winning opening guide 46a, and the other (seven) cutouts are all general winning opening guide 46b. ing.

  The specific winning opening guide 46a has a notch deeper toward the center than the other general winning opening guide 46b, and is distinguished from the general winning opening guide 46b in terms of form. In addition, a decorative border is provided around the specific winning opening guide 46a so as to visually distinguish it, and the alphabet "V" is designed at a position near the center of the ball sorting member 46. Decorated body.

(3-1-1. When the ball stopping member is not operating)
The ball stopping member 44 can reciprocate so as to advance and retreat from the side (in this example, the right side) with respect to the low probability path 36. The center accessory 6 is equipped with a ball stop solenoid (hereinafter simply referred to as “solenoid”) 54, and this solenoid 54 is connected via a link mechanism (not shown). The ball stopping member 44 can be actuated (advanced / retracted). In the first embodiment, when the solenoid 54 is not energized (de-energized), the ball retaining member 44 is inoperative, and at this time, the ball 54 is held in a state of being advanced with respect to the low probability path 36.

  As shown in FIG. 4, when the ball retaining member 44 is not in operation, the tip portion thereof enters the low probability path 36 from the right side. In this state, the game ball that has passed through the low probability path 36 comes into contact with the tip of the ball retaining member 44 in the vicinity of the end thereof, and at this time, as shown by the arrow in the figure, it faces the ball distribution member 46. And is guided to roll.

  Each of the winning opening guide portions 46a and 46b is opened in the radial direction from the periphery of the ball sorting member 46, and therefore has a relative relationship capable of receiving a rolling game ball. On the other hand, since the ball sorting member 46 is rotated in a certain direction (clockwise as viewed from above) in the normal gaming state, etc., all the eight winning opening guides 46a and 46b have a probability of 1/8 each. A game ball may enter.

(3-1-2. During operation of ball stopping member)
Next, FIG. 5 shows the time of operation of the ball retaining member 44. When the solenoid 54 is energized, the ball retaining member 44 is activated, and the tip portion thereof is retracted outward from the low probability path 36. In this case, the game ball passing through the low probability path 36 passes through the side of the ball sorting member 46 as it is without coming into contact with the ball retaining member 44 in the vicinity of the terminal end. The above-mentioned general winning opening 56 is formed at the end position of the low probability path 36, and the game ball that has reached this point enters the general winning opening 56 and is released through the above-described ball discharge passage 51 as it is.

(3-2. Passing through high probability path)
FIG. 6 shows an operation mechanism of the ball path changing member 34. As described above, a ball path changing portion solenoid (hereinafter sometimes simply referred to as “solenoid”) 58 is disposed in the center accessory 6 so as to be attached to the ball path changing member 34. In a state where the solenoid 58 is not energized (de-energized), the ball path changing member 34 is tilted to the left as viewed from the front as shown by a solid line in FIG. The state will be described as a stopped state of the ball path changing member 34.

  On the other hand, when the solenoid 58 is energized, as shown by a two-dot chain line in FIG. 6, one end portion (the left end portion in this example) of the ball path changing member 34 is pulled up via the mechanism elements 58a and 58b. Therefore, as described above, the ball path changing member 34 falls to the right side (operating state).

  FIG. 7 shows a state where a game ball is guided through the high probability path 38 in the center accessory 6. When the game ball rolls at the timing when the ball path changing member 34 is actuated, the game ball is guided leftward and sent to the high probability path 38. In FIG. 7, each part (upper part and front side) of the center accessory 6 is shown in a partially cut or broken state.

(3-2-1. Ball falling part)
Below the liquid crystal display 40, the downstream portion of the high probability path 38 extends so as to protrude above the ball sorting member 46, and a ball dropping portion 38a is formed at the terminal position. The ball dropping part 38a has a hole formed at the lower end thereof, and the game ball can be dropped through the hole. The ball dropping part 38 a is located just above the center (not necessarily the exact center) of the ball sorting member 46, and the game ball dropped from the hole falls onto the ball sorting member 46. .

  The hole at the lower end of the ball dropping portion 38a is formed to have a size that allows only one game ball to pass through, but a funnel-shaped (or tapered, mortar-shaped) smooth guide surface is formed above it. Has been. For this reason, as shown by the arrows in FIG. 7, when the game ball that has rolled on the high probability path 38 reaches the ball dropping part 38a, it turns along the funnel-shaped guide surface and gradually gains momentum. Drops into the hole at the bottom while weakening. At this time, the time required for the game ball to fall from the ball drop portion 38a is not always constant, and it becomes non-uniform depending on the rolling state of the game ball (the momentum and the entry path when entering the ball drop portion 38a). Even if it is a product of this, a product individual difference etc. will arise. Or even if it restricts to the same pachinko machine 1, since it will be influenced by the inclination of the stand at that time, installation situation, secular change, etc., the time required for the game ball to fall through the ball drop part 38a (movement time) ) Is hardly constant. Note that such a function of the ball dropping portion 38a corresponds to a so-called “one-hole cloon”.

(3-2-2. Behavior on ball sorting member)
FIG. 8 shows the behavior of the game ball on the ball sorting member 46. A slightly larger stage 46c is formed at the center of the upper surface of the ball sorting member 46, and the game ball dropped from the ball dropping portion 38a as described above lands at the substantially center on the stage 46c. The periphery of the stage 46c is surrounded by four partition walls 46d, but a passage through which a game ball can pass is secured at a break portion between the partition walls 46d.

  On the other hand, the stage 46c has a shape whose upper surface is raised to a middle height. For this reason, there is a possibility that the game ball dropped on the stage 46c rolls in four directions through each cut portion as indicated by arrows in FIG. At this time, since one of the breaks is connected to the specific winning opening guide section 46a, the game ball dropped on the stage 46c can enter the specific winning opening guide section 46a with a probability of 1/4.

(3-3. Ball sorting operation)
FIG. 9 shows a ball sorting operation when a game ball enters the general winning opening guide 46b. As described above, the general winning opening guide 46b is a relatively shallow notch as viewed from the periphery of the ball sorting member 46, and its depth is slightly larger than the diameter of the game ball. The entered game ball is transferred in the circumferential direction along with the rotation of the ball sorting member 46 while being pressed against the wall surface surrounding the ball sorting member 46 ((a) in FIG. 9).

  Although only a part is shown in FIG. 9, the specific winning opening 60 that is one aspect of the specific area in the first embodiment is formed below the ball sorting member 46, and the specific winning opening 60 is It is located on the inner side with a distance from the wall surface surrounding the ball distribution member 46. For this reason, even if the game ball is positioned above the specific winning opening 60 in the state of entering the general winning opening guide 46b, it cannot fall into the specific winning opening 60 from there, and passes through it. Will be transferred.

  Thereafter, as shown in FIG. 9 (b), the game ball circulates around as the ball distribution member 46 rotates, to the rear of the general winning opening 50 (clockwise at 2 o'clock). When transferred, the game ball is discharged from the general winning opening guide 46b. The released game ball rolls on the guide surface 62 and falls into the general winning opening 50.

  On the other hand, the specific winning opening guide 46a is a relatively deep notch, and the depth thereof is sufficiently larger than the diameter of the game ball. Furthermore, a ball stopper 46e is formed along the periphery of the ball sorting member 46 in the specific winning opening guide 46a, and the game ball that has entered the specific winning opening guide 46a is located deeper than the ball stopper 46e. Held in. Therefore, the game ball that has entered the specific winning opening guide 46a is transferred in the rotational direction while being located slightly away from the peripheral wall surface surrounding the ball sorting member 46, that is, slightly closer to the inside of the ball sorting member 46. It will be.

  FIG. 10 shows a state in which the game balls that have entered the specific winning opening guide 46a are transferred. As described above, the game ball that has entered the specific winning opening guide 46a is positioned on the inner side from the peripheral wall surface surrounding the ball sorting member 46 ((a) in FIG. 10). If the game ball is positioned above the ball, it can fall into the specific winning opening 60, that is, pass through the specific area. Further, the fall of the game ball to the specific winning opening 60 (hereinafter referred to as “V winning”) is detected by the specific area switch 52 described above. In the first embodiment, terms such as “specific prize opening” and “V prize” are used for convenience. However, this is caused by the fall of the game ball to the specific prize opening 60 to some advantage. In order to recall this, it is not essential that the game ball is actually guided to the back side of the board or awarded.

  As described above, when the ball distribution member 46 receives the game ball, the ball distribution member 46 rotates in a state where the ball is received in the specific prize opening guide part 46a or the general prize opening guide part 46b, thereby specifying the destination of the game ball in the specific prize opening. 60 and the general winning opening 50. The distribution destination is determined depending on whether the game ball enters the specific winning opening guide 46a or the general winning opening guide 46b. Which guide the game ball enters is determined when the game ball is received. It depends on the posture of the ball sorting member 46.

(3-3-1. Sorting operation in the case of low probability path)
When the game ball has passed through the low probability path 36, the ball sorting member 46 receives the game ball from the outer peripheral direction. In this case, there is a possibility that the game ball may enter all of the eight guide portions 46a and 46b, but in reality, any of the eight guide portions at the timing when the game ball rolls from the vicinity of the end of the low probability path 36. Depending on whether 46a and 46b are opposed to the game ball, the destination is naturally determined.

  Therefore, if the ball sorting member 46 takes an attitude in which the specific winning opening guide 46a is opposed to the gaming ball when the game ball is received, the gaming ball can enter the specific winning opening guide 46a as it is. After that, the destination is distributed to the specific winning opening 60.

  On the other hand, if the ball sorting member 46 is in a posture to make the general winning opening guide 46b relatively to the gaming ball when the game ball is received, the gaming ball enters the general winning opening guide 46b, and thereafter The destination can be sorted to the general winning opening 50.

  At this time, since there is one specific winning opening guide 46a out of all eight, as a result, when a game ball is guided through the low probability path 36, the probability of winning a V in the future is 1/8. . However, this probability is based on the premise that the game ball is guided to the ball stopping member 44. If the ball stopping member 44 is retracted as described above, it is not received by the ball sorting member 46. The general winning opening 50 may be entered as it is. In the first embodiment, no special benefits are prepared for the game ball entering the general winning opening 50. However, in the previous stage, the winning entry to the big winning opening 26 was detected first. Sometimes prize balls are paid out.

(3-3-2. Distributing operation in case of high probability path)
The same can be considered when the game ball is guided through the high probability route 38. In this case, since the ball distribution member 46 receives the game ball on the stage 46c, it is assigned to one of the specific prize opening guide part 46a or the three general prize opening guide parts 46b as described above. A game ball may enter. However, since the game ball tends to roll in a direction in which the downward inclination of the stage 46c is larger, the stage 46c is designed to have a certain inclination (for example, having a downward inclination on the front side, etc.) due to the design of the ball sorting member 46. Is given, the game ball is distributed based on the inclination.

  Therefore, considering the above inclination, if the ball distribution member 46 receives the game ball on the stage 46c and the posture for positioning the specific winning opening guide 46a is on the near side, the game ball is Since it is possible to enter the specific winning opening guide 46a according to the inclination, the destination is distributed to the specific winning opening 60 thereafter.

  On the other hand, if the ball distribution member 46 receives the game ball on the stage 46c, the game ball is positioned as a general prize opening if the other three general prize opening guide portions 46b are positioned on the front side. After entering the guide part 46b, the destination is distributed to the general winning opening 50.

  Therefore, when a game ball is guided through the high probability path 38, the probability of winning a V in the future is reduced to a quarter, and as a result, the probability of V winning is higher than in the case of being guided through the low probability path 36. It can be said that.

(4. Supplement of production elements)
The center accessory 6 is provided with decorative designs at various locations, and decorative lamps / LEDs (not shown in particular) are arranged therein as production elements. The decoration lamp / LED can perform an effect by light-emitting decoration according to the progress of the game, or can perform demonstration light emission while the pachinko machine 1 is waiting.

  FIG. 11 specifically shows the notice effect character 64 attached to the center accessory 6. The notice effect character 64 is arranged so that it can appear from between the left and right big prize openings 26 in the center accessory 6 (see FIG. 2). Specifically, the effect solenoid (character drive) shown in FIG. Solenoid) 66, and appears to be visually recognized by the player at this time.

  The notice effect character 64 is normally hidden in a state of being collapsed to the back side of the center accessory 6, but appears when the effect solenoid 66 is energized under certain conditions. That is, when the effect solenoid 66 is energized, the notice effect character 64 turns about 90 ° to the near side via the mechanism element 66a, and rises to the near side as shown.

  In the normal gaming state, for example, based on the relative relationship between the timing at which the game ball is detected by the big prize opening count switch 28 and the attitude (rotation angle) of the ball sorting member 46 at that time, The notice effect character 64 appears when it is easy to enter the guide 46a.

  As another aspect, the game ball is based on the relative relationship between the timing at which the game ball is detected by the special winning opening count switch 28 and the posture of the ball path changing member 34 (whether it swings to the left or right). Is the timing at which it is easy to be sent to the high probability path 38, the notice effect character 64 appears.

  Further, in the case of the first embodiment, in accordance with the appearance of the notice effect character 64, the surroundings are lit up by illumination of a decoration lamp / LED, or a sound effect is generated to visually and auditorily give notice. It is intended to enhance the effects of the production.

(5. Configuration of control system)
Next, a configuration for controlling the game operation and the rendering operation by the pachinko machine 1 will be described.

  FIG. 12 schematically shows a part of the configuration related to the electronic devices of the pachinko machine 1. The pachinko machine 1 has a main control board (main board) 68 for controlling game operations and a sub-control board 70 for controlling various performance operations. These boards are connected to each other through wiring. In addition, electronic devices are connected to each board. All of these boards are arranged on the back side of the pachinko machine 1 and are usually not visible to the player.

  Further, a payout control board 72 is connected to the main control board 68, and this payout control board 72 controls the operation of a prize ball apparatus (not shown). A discharge control board 74 is further connected to the payout control board 72, and this discharge control board 74 controls the operation of a not-shown launch motor.

  Note that the pachinko machine 1 is also equipped with a power supply unit board, an interface board (in the case of a CR machine), and the like.

(5-1. Main control board)
The main control board 68 includes electronic components such as a CPU, RAM, ROM, and input / output interface (not shown). The main control board 68 is connected to the above-mentioned large winning opening count switch 28 and the specific area switch 52, and also includes sensors such as a once starting opening switch 76, a twice starting opening switch 78, and other winning opening switches 80. It is connected. Among these, the once and twice start port switches 76 and 78 detect that the corresponding one and two start ports 12 and 14 have been won, respectively, and output detection signals to the main control board 68. . In addition, winnings in the normal winning openings 8, 10 and the center winning combination 6 are detected by a plurality of other winning opening switches 80 corresponding to each, and the detection signal is the main control board 68. Is output.

  On the other hand, the operation of the driving elements such as the above-mentioned large winning opening solenoid 82, the ball path changing portion solenoid 58 and the ball stopping portion solenoid 54 is controlled based on the driving signal from the main control board 68. Yes.

  Further, a ball allocating unit motor 84 is provided in the center accessory 6, and the sphere allocating unit motor 84 can rotate the sphere distributing member 46 based on a command signal from the main control board 68. it can. Further, a motor index sensor 86 is attached to the ball distribution motor 84, and an index signal is input from the motor index sensor 86 to the main control board 68. Each control board is housed in a board box (not shown). In particular, the main control board 68 controls the progress of the game, and in this embodiment, the movable piece 24 of the center accessory 6 that determines whether or not to shift to a special game state that gives a profit to the player. And the ball sorter 46 are controlled. For this reason, the main control board 68 is housed in a board box that cannot be opened when the board box is sealed once, leaving a broken trace of the sealed part. That is, the board box for storing the main control board 68 is illegally strengthened. Thereby, since the microprocessor mounted on the main control board 68 performs various programs such as illegal row detection processing to be performed later, it is possible to prevent the various programs from being tampered with.

(5-2. Sub-control board)
Further, as the effect element, the speaker 88, the effect lamp / LED 90 and the like are connected to the sub-control board 70. While the game by the pachinko machine 1 is in progress, the sub-control board 70 controls the production operation based on the command signal transmitted from the main control board 68, and controls the production by the sound output or the lighting decoration according to a certain production pattern. ing. The effect solenoid 66 is also connected to the sub-control board 70, and the appearance action of the notice effect character 64 is controlled by the sub-control board 70.

  As an effect element using an image, the liquid crystal display 40 is connected to the sub-control board 70 via the liquid crystal control board 92, and a drawing command for the liquid crystal display 40 is output from the sub-control board 70. It has become.

  In the first embodiment, when a game ball is sent to the high probability path 38 in the center accessory 6, the high probability path passage switch 39 is provided with the sub control board 70 in order to perform an effect with a particularly high priority. It is connected to the. When the sub-control board 70 receives the detection signal from the high probability path passing switch 39, the sub-control board 70 performs a special effect display in preference to the normal display image.

(6. Details of control processing)
Next, the contents of the control process performed by the main control board 68 and the sub control board 70 will be described. In the following description, the control content related to the operation of the center accessory 6 is mainly taken up.

(6-1. When power is turned on)
FIG. 13 is a timing chart showing processing at power-on and the states of various switches. In FIG. 13 and subsequent figures, the “operating state” of each member means that the corresponding solenoid or motor is energized / driven, and conversely, the “stopped state” means that the solenoid or motor is not energized / driven. Means non-driven.

  When the power of the pachinko machine 1 is turned on, the CPU of the main control board 68 executes a self-diagnosis process and a power failure recovery process, and takes over the game contents backed up at the previous power-off and starts a normal process.

  Explaining along the timing chart of FIG. 13, first, the detection function of each of the start port switches 76 and 78 is validated by turning on the power. As a result, the first start port 12 and the second start port 14 each have a function (start function) for starting the operation of the center accessory 6 when a game ball enters and a function for performing a prize ball operation (prize ball function). Both are valid.

  Normally, when the power is turned on, the input signals from the start port switches 76 and 78 are not won, and the big prize port 26 is closed (the big prize port solenoid 82 is not energized). In this case, the function of the specific area switch 52 is disabled.

  On the other hand, in the center accessory 6, the ball path changing member 34 and the ball stopping member 44 are both stopped, but the ball sorting member 46 is activated when the power is turned on. At this time, the ball distribution member 46 is rotated at a constant rotational speed A (for example, about 1.9 seconds per rotation).

(6-2.1 times when winning at the starting point)
FIG. 14 shows the processing when there is a winning at the start port 12 once during the normal game. In this case, when a detection signal is input from the start port switch 76 to the main control board 68 once (no win → win), the main control board 68 invalidates the function (start function) of each start port switch 76, 78. And the function of the specific area switch 52 is activated. Then, the main control board 68 operates the special winning opening solenoid 82 after a predetermined time (for example, 1004 ms) has elapsed, and opens the special winning opening 26 once (for example, 400 ms). In the timing charts of FIG. 14 and subsequent figures, while the functions of the start port switches 76 and 78 are disabled, only the start function is disabled, and the prize ball function is still enabled.

  In connection with the opening operation of the big prize opening 26, the main control board 68 operates the ball path changing member 34 intermittently only twice according to a fixed pattern. As a result, the game ball won in the big winning opening 26 is guided to either the low probability route 36 or the high probability route 38.

  When there is a winning at the start port 12 once, the main control board 68 decelerates the ball sorting member 46 to a rotational speed C (for example, about 5.6 seconds per rotation) and the ball stopping member 44 is in an activated state. Alternately switch to and stop state. As a result, the ball stopping member 44 alternately retreats or enters the low-probability path 36, and in accordance with this, the character body 42 swings his / her head left and right. The operation state and the stop state of the ball retaining member 44 are periodically switched, and during this time, the solenoid 54 is driven with a duty ratio of about 50%. Therefore, in FIG. 14, the operation time a and the stop time b of the ball retaining member 44 are set to be substantially the same (a> b, a <b, a = b may be satisfied). Further, the operation time a and the stop time b of the ball retaining member 44 can be the same in FIG.

  Thereafter, the main control board 68 restores (enables) the functions of the start port switches 76 and 78 when a predetermined time (for example, 0.4 seconds) elapses after the special winning opening 26 is closed. At the same time, when a certain time (for example, 8 seconds) has passed since the special winning opening 26 is closed, the function of the specific area switch 52 is invalidated and the operation state of the ball sorting member 46 is set to the rotational speed A. Return (rotation speed C → A).

(6-3.2 When winning a prize at the starting point)
FIG. 15 shows the processing when there is a winning at the start port 14 twice during the normal game. In this case, when a detection signal is input to the main control board 68 from the start opening switch 78 twice (no win → winning), the main control board 68 invalidates the functions of the start opening switches 76 and 78 and specifies The function of the area switch 52 is activated. Then, the main control board 68 operates the special winning opening solenoid 82 after a predetermined time (for example, 1004 ms) has elapsed, and opens the special winning opening 26 intermittently twice (for example, every 400 ms). In addition, a predetermined waiting time (for example, 1004 ms) is secured between the first opening and the second opening.

  In relation to the opening operation (two times) of the special winning opening 26 as described above, the main control board 68 operates the ball path changing member 34 intermittently three times according to a certain pattern. As a result, a relatively large number of opportunities are provided for the game balls that have won the big prize opening 26 to be guided to the high probability path 38.

  When there is a prize at the start port 14 twice, the main control board 68 decelerates the ball sorting member 46 to the rotational speed C and switches the ball stopping member 44 alternately between the operating state and the stopped state. As a result, the ball stopping member 44 alternately retreats or enters the low-probability path 36, and in accordance with this, the character body 42 swings his / her head left and right.

  At this time, the operation time of the ball stopping member 44 is longer than that in the case where the winning at the start port 12 is once, and the number of times that the operation state and the stop state of the ball stopping member 44 are periodically switched is set. Yes. The drive duty ratio of the solenoid 54 is approximately 50% and may be the same as that at the time of winning the start port 12 once.

  Similarly, the main control board 68 returns (validates) the functions of the start port switches 76 and 78 when a predetermined time (for example, 0.4 seconds) elapses after the special winning opening 26 is closed. When a certain time (for example, 8 seconds) elapses after closing the special winning opening 26, the function of the specific area switch 52 is invalidated and the operating state of the ball sorting member 46 is returned to the rotational speed A. The (rotational speed C → A) process is the same as that when winning the start opening 12 once.

  In the first embodiment, the rotational speed of the ball sorting member 46 is changed (A) when the big winning opening 26 is opened in response to a winning at the starting opening 12 once or twice at the starting opening 14 in FIGS. → C), for example, it is a specification that does not work with a game method in which, for example, a number of game balls are launched aiming at a specific rotation angle of the ball sorting member 46, and thereby hitting a big hit .

(6-4. Special gaming state)
Next, FIG. 16 shows a process when a game ball wins a V prize in the center accessory 6. In the pachinko machine 1 according to the first embodiment, when a V is won in the normal gaming state, a special game state (big hit game) is given a privilege that a specific condition is satisfied.

  As shown in FIG. 16, when the passing of the game ball is detected by the specific area switch 52 (ON), the game shifts to a big hit game.

(6-4-1. Round operation)
When shifting to the big hit game, the center accessory 6 is operated in a predetermined operation pattern. The operation pattern at this time is one in which the opening / closing operation of the special winning opening 26 is periodically repeated, and the number of times of opening is set to 18 at the maximum.

  As described above, a predetermined production time is provided before the opening / closing of the big prize opening 26 is started as a big hit game, and a so-called round lottery production is performed during this time. The lottery itself is performed at the timing when the game ball wins at the first start port 12 or the second start port 14 which has been the trigger of the big hit, but the round lottery effect is an animation display by the liquid crystal display 40 and the speaker 88. It is executed by the sound output from.

  Further, when the main control board 68 receives the detection signal from the specific area switch 52, the main control board 68 first switches the operation state of the ball sorting member 46 to the rotation speed B (for example, about 3.7 seconds per rotation), and then the rotation speed A. Switch to.

  In this way, while the round lottery effect is in progress, the rotation speed of the ball sorting member 46 is switched to two stages. During this process, the main control board 68 outputs the third index signal from the motor index sensor 86. Upon reception, the rotation of the ball sorting member 46 is stopped there. In the case of the first embodiment, when the ball sorting member 46 is stopped at the timing when the index signal is received, the specific winning opening guide 46a in this state terminates the low probability path 36 (a direction in which a game ball can be received). Is positioned relative to. Further, since the ball path changing member 34 is held in a stopped state, the ball path changing member 34 remains fixed in a posture for guiding the game ball to the low probability path 36 during this period.

  When the above-described round lottery effect is completed, and the player is notified of the number of winning rounds, the main control board 68 starts the opening / closing operation of the big prize opening 26 according to the sequence of the big hit game. In accordance with this, the main control board 68 activates the function of the specific area switch 52.

(6-4-2. Continuation of round operation)
In the case of the first embodiment, the jackpot game can be continued up to 15 rounds, and the end condition of one round is, for example, that any one of the following (1) to (3) is satisfied.
(1) When the number of times of opening / closing the grand prize winning opening 26 has reached 18 times.
(2) When the number of game balls won in the big winning opening 26 reaches ten.
(3) When a game ball is detected by the specific area switch 52.

  In addition, the continuation condition to the next round in the big hit game is that the game ball is detected by the specific area switch 52, that is, V winning. However, in the fifteenth round, even if a game ball is detected by the specific area switch 52, the round is not continued.

  In addition, the round lottery is performed based on the counter value acquired by the main control board 68 at the timing when the game ball wins the first start port 12 or the second start port 14. There are 2 rounds, 7 rounds, and 15 rounds, and the probabilities are 1/3 each.

(6-4-3. Continuation plan means)
Regardless of the result of the lottery, the first round after the transition to the big hit game is always planned to continue to the next round. Alternatively, when the lottery result is 15 rounds, continuation to the next round is scheduled for all the second to fourteenth rounds.

(A. Execution of guidance operation)
In these cases, as shown in FIG. 16, the ball path changing member 34 is in a state of guiding the game ball to the low probability path 36 during the round execution. The winning opening guide 46a stops in a posture that makes it easy to receive the game ball, and the ball retaining member 44 has advanced toward the low probability path 36. Therefore, the first game ball that has won the big winning opening 26 during the round is first guided to the specific winning opening guide 46 a through the low probability path 36.

  Thereafter, when the number of winning balls to the big winning opening 26 increases from 2 to 5, the game ball (first winning prize) that has entered the specific winning opening guide 46a in the center role 6 From there, the following game balls (winning 2nd to 5th) stop in one row in the low probability path 36.

  However, if the sixth winning ball is counted before the opening of the special winning opening 26 reaches 18 times, as shown by the broken line in FIG. The control board 68 operates the ball retaining member 44. In this case, since the ball stopping member 44 is retracted to the outside from the low-probability path 36, the game balls (third to fifth) that have been stopped until then lose support, and remain in the low-probability path 36 as they are. It rolls in the downstream direction and falls to the general winning opening 50.

  Further, when the main control board 68 ends the round (one segment) for the time being, either the 10 winning balls are detected by the special winning opening count switch 28 or the special winning opening 26 is opened or closed 18 times. With the earlier timing as a trigger, the rotation of the ball sorting member 46 is resumed after a predetermined time (for example, 1.8 seconds) has elapsed. At this time, since the first winning ball has already entered the specific winning opening guide 46a, the gaming ball surely wins V. As a result, since the passing of the game ball is detected by the specific area switch 52, the continuation to the next round is confirmed.

  However, even if the continuation to the next round is scheduled as described above, if the player is not allowed to win the big winning opening 26, the continuation condition is not satisfied, and the big hit game ends there. . In this case, as shown in FIG. 16, when a predetermined time (for example, 8 seconds) elapses after the opening / closing operation of the big prize opening 26 is stopped, the main control board 68 functions the start port switches 76, 78. Is enabled while the function of the specific area switch 52 is disabled. At the same time, the main control board 68 returns the operating state of the ball sorting member 46 to the rotational speed A (high speed) and returns the ball retaining member 44 to the stopped state.

  FIG. 17 shows the processing in the round continued during the big hit game. The content of the processing is almost the same as in the case of FIG. 16, but here the passage of the game ball is detected by the specific area switch 52 because the period for the round lottery effect is not prepared. The time until the opening / closing operation is started (for example, 4 seconds) is shortened.

(B. Stopping guidance operation)
The processes in FIGS. 16 and 17 are the contents when continuation to the next round is scheduled. On the other hand, when the result of the round lottery is 2 rounds or 7 rounds, the continuation to the 3rd round or later or the 8th round or later is not scheduled in principle. For this reason, when the result of the round lottery is the second round or the seventh round, the process (guide operation) for actively shifting to the next round is not performed in the round (the second round or the seventh round).

  FIG. 18 shows the process when the continuation to the next round is not scheduled, that is, the process of the second round or the seventh round determined as the final round as a result of the round lottery. In this case, the main control board 68 once stops the ball sorting member 46 at a fixed position at the start of the second round or the seventh round (before the big prize opening 26 is opened), and then opens and closes the big prize opening 26. The rotation of the ball sorting member 46 is started in synchronization with the timing of starting the operation (time ts). Thereafter, the rotation of the ball sorting member 46 is maintained, and the ball sorting member 46 remains rotated at a constant speed B (medium speed) during the round.

  In accordance with this, the main control board 68 repeatedly executes the forward / backward movement of the ball retaining member 44. This operation is also performed in synchronization with the rotation of the ball distributing member 46. The member 44 is driven to a forward state and a backward state with a duty factor of approximately 50%.

  Therefore, at this time, the main control board 68 retreats the ball stopping member 44 at the timing when the specific winning opening guide 46a opposes, for example, near the end of the low probability path 36, and conversely the timing at which the general winning opening guide 46b opposes. Then, by advancing the ball stopping member 44, it is possible to stop the operation of guiding the game ball that has passed through the low probability path 36 to the specific winning opening guide 46a.

(6-4-4. Granting a prize opportunity)
If the V-winning is not won in the second round or the seventh round, the round continuation condition is not satisfied, and the big hit game ends in the round. However, the pachinko machine 1 according to the first embodiment has a specification that allows a round to be continued (a V-winning is possible) by a player's technical intervention, and the specific specification will be described below.

  In other words, in the first embodiment, the specification is such that an opportunity to make a V prize by technical intervention is provided only once at a specific timing during a round. This is when the ball reaches the seventh count. For example, the game ball (seventh) that has won the grand prize opening 26 at this specific timing is given an opportunity to win a V in the following manner, for example.

  First, the main control board 68 fixes the ball path changing member 34 in a stopped state until the number of winning balls to the big winning opening 26 reaches 6 counts (time ts to time tc). Any game balls that have won the winning opening 26 are sent to the low probability path 36. When the game ball is guided to the ball stopping member 44 in the vicinity of its terminal end, it enters the general winning opening guide 46b, and conversely, when it is not guided to the ball stopping member 44, it falls to the general winning opening 50 as it is.

  In contrast, when the winning ball reaches 7 counts (time tc), the main control board 68 operates the ball path changing member 34 for a predetermined time (for example, 1.2 seconds) using this as a trigger. As a result, the game ball won in the seventh count is almost certainly sent to the high probability path 38. In this case, since the game ball passes through the high probability path 38 and falls onto the stage 46c of the ball sorting member 46, the game ball can enter the specific winning opening guide 46a with a probability of 1/4.

  Also, in this case, the game ball won in the seventh count is given an opportunity to win a V regardless of the guiding operation by the ball stopping member 44, and the V winning probability at that time is a comparatively 1/4. It is set high. Therefore, even if the player is simply playing a game, if he can win 7 in the big prize opening 26, he will always have a chance of winning a V prize with a probability of a quarter, that is, challenge the continuation of the round. Have an opportunity to do. As a result, even a player who has played a game casually will know that there is a possibility that he can win a round continuation if he can win up to the seventh count, and the motivation for the game will increase naturally.

  The specifications of the pachinko machine 1 as described above are extremely excellent in that the content can be equally beneficial for all, regardless of whether or not the player specifically recognizes the contents as information. The utility of such specifications is remarkable when a player who is not very skilled (beginner), a player who is not familiar with information, a player who is not interested in technical intervention originally played a game with the pachinko machine 1, etc. Become.

  Further, in the first embodiment, the winning ball of the seventh count can be guided to a different route (high probability path 38), so that a game is given that an opportunity for V winning is given by a visual change. Easy to recognize. Therefore, even if the player does not know the specifications of the technical intervention as information, the pachinko machine 1 of the first embodiment can easily understand the specifications just by looking at the movement of the game ball. It is possible to provide a game that is easy for everyone to understand and interesting.

(A. Synchronization with the opening and closing operation of the prize winning opening)
The technical intervention specification by the pachinko machine 1 according to the first embodiment is not only a chance at the seventh count, but is further advanced and more advanced elements are added.

  In other words, in a round that is not scheduled to continue, the ball sorting member 46 starts rotating at the timing when the first opening / closing operation of the big prize opening 26 is started as described above (time ts). At this time, the opening / closing operation of the special winning opening 26 is repeated at a constant cycle, and the rotational speed (angular velocity) of the ball sorting member 46 is constant. The posture (rotation angle) of the minute member 46 and the timing at which the special winning opening 26 is opened are synchronized with a certain relative relationship.

  For this reason, if the player has deeper observation and exploration, he / she should play the game after understanding the relative relationship between the timing of opening the special winning opening 26 and the rotation angle of the ball sorting member 46. Is possible. Therefore, for example, while the player observes the pachinko machine 1 well, if the player makes a 7th count at the opening timing, it is possible for the player to determine whether the player is likely to win a V. It is. Players who have arrived so far will have a greater enjoyment of technical intervention than other average players, and will be able to feel great satisfaction in continuing the round as a result.

(B. Non-uniformity when the ball is dropped)
However, if the behavior always continues mechanically, the player may get bored and the interest in technical intervention may be halved. In this regard, in the pachinko machine 1 according to the first embodiment, since the ball dropping portion (one-hole croon) 38a is formed at the terminal position of the high probability path 38, the game ball falls while turning. Therefore, non-uniformity will occur in the time required for dropping.

  In this case, based on the relative relationship between the opening / closing operation timing of the big winning opening 26 and the rotation angle of the ball sorting member 46, it is assumed that the player can easily determine the opening timing at which the player can easily win V at the seventh count. However, the game ball does not always exhibit the same behavior (the movement time from when the ball is entered until it is received by the ball sorting member 46) at the point where it enters the special winning opening 26. Thereby, the arrival of the player's tiredness can be delayed, and the difference in the number of balls due to the difference in the technique of the player can be reduced.

  In addition, even if the player plays the game after understanding the general specifications, whether or not the round can be continued successfully by technical intervention depends on the individual differences of the pachinko machine 1 and variations due to accidental effects. Therefore, an interesting element from another viewpoint is added. Therefore, for players who are actively involved in technical intervention, the enjoyment of playing games while identifying the non-uniform factors due to individual product differences increases, so for players who have further studied the specifications and characteristics of the pachinko machine 1, In addition to the success of his own technical intervention, he can get great satisfaction with the achievements such as rounding around the hall and choosing a platform.

(6-5. Final round)
FIG. 19 shows processing in the final round (15 rounds). Not only when the lottery was performed at the start of the opening 12 and 14, but when it was 15 rounds, despite the lottery result of 2 rounds or 7 rounds, if the big hit game could be continued up to 15 rounds, In the final round, the following processing is performed.

  Here, first, when a detection signal from the specific area switch 52 is input, the main control board 68 disables the function of the specific area switch 52 and does not enable it until the end of the round. Further, the main control board 68 temporarily stops the ball sorting member 46 based on the index signal from the motor index sensor 86, but the rotation of the ball sorting member 46 is synchronized with the timing at which the big winning opening 26 is opened. To start. Further, the ball retaining member 44 is switched to the operating state in accordance with this and maintained as it is until the end of the round. On the other hand, since the ball path changing member 34 remains in a stopped state until the end of the round, the game ball won in the big winning opening 26 passes through the low probability path 36 and is not received by the ball sorting member 46. It simply falls to the general winning opening 50.

  Through the above process, the V-winning is avoided in the final round. Therefore, when either of the winnings at the big winning opening 26 reaches 10 counts or the big winning opening 26 is opened 18 times, As a result, the final round ends, and the main control board 68 ends a series of big hit game processes.

(7. Supplement on timing chart)
The description of the processing with reference to the timing charts of FIGS. 13 to 19 is completed as described above, but the points to be supplemented with respect to the description of these drawings are listed below.

  (1) In FIGS. 13 to 19, symbols with arrows (A, B, C) attached to the state change of the ball sorting member represent the rotation speed within the designated period. ing.

  (2) In FIG. 14 or FIG. 15, when the passage of the game ball is detected within the effective period of the specific area switch 52, the main control board 68 proceeds to the process of FIG.

  (3) In FIG. 16 to FIG. 19, the end timing of the opening operation of the big prize opening is the earlier of the 18th closing time or 10 winning prizes.

  (4) In FIG. 16 and FIG. 17, the portion indicated by a broken line as the state change of the ball stopping member during the opening / closing operation of the big prize opening is, as a rule, switched to the operation state of the ball stopping member 44 at 6 counts. Represents that. However, if the 6th count is not reached, the ball stopping member 44 operates at the 18th closing time of the grand prize winning opening 26, and if the 6th count is reached before the grand winning opening 26 is opened, Operates at 10 counts.

  (5) In FIG. 17 and FIG. 18, the portions indicated by broken lines as the state changes of the ball sorting member and the ball retaining member at the time of starting of the specific area switch are the rounds of the ball sorting member and the ball retaining member, respectively. If it is in operation, it is in the operating state at that time. Conversely, if it is in the stopping state, it indicates that it changes from the stopped state to the operating state at the rise of the detection signal by the specific area switch.

  (6) Similarly, in FIG. 19, the portion indicated by a broken line as a change in the state of the ball retaining member when the specific area switch is started is in the operating state at that time if the ball retaining member was operating in the previous round. On the other hand, when the vehicle is stopped, it indicates that the detection signal is changed from the stopped state to the operating state at the rising edge of the detection signal by the specific area switch.

(8. Round lottery effect processing)
Next, the round lottery effect process will be described in detail. As already described in (6-4-1. Round operation) above, the round lottery itself is performed when a winning is detected by each start port switch 76, 78 (decision means). In the pachinko machine 1 according to the first embodiment, a round lottery effect and a promotion effect are executed during the big hit game. At this time, the number of rounds selected by lottery is one of a relatively high stage (15 rounds), a relatively medium stage (7 rounds), or a relatively low stage (2 rounds). The lottery probabilities for each round are equally one third.

  FIG. 20 shows an example of an image displayed on the liquid crystal display 40 when a big hit is made in the normal gaming state (when V is won). In this example, the screen up to that point is changed over, the “big hit” character is displayed on the screen in a decorative manner, and a state of a stunning operation by a plurality of characters is drawn. A voice message or sound effect is output from the speaker 88 with the output of these images.

(8-1. Notification means)
Next, FIG. 21 has shown an example of the image displayed as an effect at the time of a round lottery. Such effect display is performed before the opening / closing operation of the big prize opening 26 is started in the first round of the big hit game. Here, as a result of the round lottery, the number of rounds scheduled to be continued can be displayed in a stunning manner by changing the decorative pattern (designed with the numbers “2”, “7”, “15”). . In the first embodiment, three types of symbols are scrolled in the vertical direction on the screen, for example, in the vertical direction, and when a certain amount of time has passed, the scrolling is stopped and the symbols are stopped and displayed.

(8-2. Temporary duration)
23 to 24 show examples of images when the symbols are stopped and displayed from the above scroll state. These images have the content of notifying the player of the result of the round lottery according to the type of symbols that are stopped and displayed, and the lottery result is 2 rounds (FIG. 22), 7 rounds (FIG. 23), or the maximum 15 The fact that it was a round (FIG. 24) is represented by a symbol.

  Before the stop display is made, the scrolled symbol (for example, “2”) is temporarily stopped, and after a short time, the symbol is changed to the next symbol (for example, “7”). In some cases, the display may change to the next symbol (for example, “15”) at a further interval, and a final stop display may be displayed there. Due to such a change in the display mode, an effect can be obtained in which the result of the round lottery is informed in a staged manner while making the player feel excited.

  Among these, when the lottery result based on the original probability of 1/3 is 7 rounds or the maximum 15 rounds, the correct lottery result is 7 rounds (FIG. 23) or 15 rounds (FIG. 24) in the round lottery effect. In some cases, it may be notified, and in some cases, an unreal lottery result is notified as an effect. Specifically, even though the true lottery result is 15 rounds, the round lottery effect may be notified as 7 rounds or 2 rounds. Alternatively, even though the true lottery result is 7 rounds, the round lottery effect may be notified as 2 rounds.

  In this way, the determination as to whether or not to notify the number of rounds that is not the true lottery result as an effect is made on the sub-control board 70 of the pachinko machine 1. When receiving a command indicating the real lottery result from the main control board 68, the sub control board 70 determines the number of rounds (maximum number of rounds) to be notified in the round lottery effect and the effect time, and based on this determination, the liquid crystal The display of the display 40 is controlled. The appearance ratio of the number of rounds notified at this time is, for example, as described in Table 1 below.

  From the appearance ratio shown in Table 1, the following is clear. In other words, since the original lottery probability of each round is 1/3 (about 33.3%), the round lottery effect is reported as 2 rounds (61.5%). Half of them show that the 7th or 15th round is the real lottery result. In other words, even if the round lottery effect is notified as 2 rounds, there are about half the cases where the promotion effect is promoted to 7 rounds or 15 rounds. Accordingly, in the first embodiment, the 2nd and 7th rounds that are notified in the round lottery effect in the case of a big win are the contents (temporary continuation period, number of tentative continuations) that are temporarily notified including the real result. It can be said. However, when 15 rounds are notified, there is no case where they are demoted to 7 rounds or 2 rounds, so the lottery result is fixed to 15 rounds at this time. By configuring the round lottery production method in this way, the player can always face a big hit game with a sense of expectation for the round promotion.

(8-3. Promotion effect means)
After the above round lottery effects are performed, further promotion effects are performed by the sub-control board 70 during the big hit game. In this promotion effect, for example, what was reported as 2 rounds is changed to a number of rounds exceeding that, that is, there is a possibility of promotion, and the effect information indicating the number of rounds after promotion is displayed by an image The contents are displayed.

  In the first embodiment, the promotion effect is performed twice during the jackpot game, and the first time is during the first round jackpot game, and the second time is during the sixth round jackpot game. For example, if the round lottery effect is informed that there are two rounds, the first promotion effect is an effect of whether it is 2 rounds, or it is promoted to 7 rounds or 15 rounds. Also, if you were informed of 7 rounds, or if you were promoted from 2 rounds to 7 rounds in the 1st promotion effect, will you remain 7 rounds in the 2nd promotion effect or will you be promoted to 15 rounds? Is promoted. If the first round lottery effect has already been notified as 15 rounds, the promotion effect is not performed. Similarly, when the first round lottery effect has already been reported as 7 rounds, the promotion effect is not performed during the first round jackpot game.

  In any case, since the real lottery results are assigned in three ways with a probability of 1/3, if the round lottery production is instructed to produce as 2 rounds or 7 rounds, the promotion will be promoted thereafter. The ratio of final promotion to 7 rounds or 15 rounds in production (first or second time) will settle down to the promotion ratios shown in Table 2 below, for example.

  FIG. 25 shows an example of an image displayed on the liquid crystal display 40 when the promotion effect is started. In this example, the character information marked “promotion chance !!” is displayed large on the screen, and the symbol (here “2”) indicating the number of rounds that were temporarily informed is displayed large. Yes. In addition, sound information indicating “promotion chance” is output from the speaker 88 and a sound effect that excites the atmosphere is output.

  When a promotion effect is implemented in the big hit game, when a game ball wins first in the big winning opening 26 after the round operation starts (first count), this is used as a trigger in the liquid crystal display 40 as shown in FIG. Will appear and the actual promotion will begin.

(8-4. Production information)
FIG. 26 to FIG. 28 respectively show examples of effect information displayed on the liquid crystal display 40 in the first (first round) promotion effect. Here, the following three display modes are listed as effect information.

  (1) A mode in which a character imitating a police officer shoots down a symbol while shooting a handgun with a comical motion against a background of symbols representing 2, 7, and 15 rounds (FIG. 26).

  (2) A graphic representing the 2, 7, and 15 rounds is drawn on the ice against the background of the curling ground, and the three-dimensional design is moving in a horizontal direction with the three-dimensional design aligned in a cage. Is displayed. Then, a three-dimensional symbol rotating by a character imitating a person with a spear in the direction of curling is guided in a curling manner, and the symbols to be positioned in front of the player are successively changed (FIG. 27). .

  (3) Patterns representing rounds 2, 7, and 15 are displayed in the depth direction against the background of the garden of a private house, and a character imitating a housewife is rhythmic in the manner of hitting a futon from behind. The mode which changes the design which should be located in front one after another while hitting (FIG. 28).

(A. Relationship between game progress and performance information)
In the first embodiment, in the promotion effect using the display modes (1) to (3) above, each display mode (character action or symbol content) changes according to the progress of the game. ing. That is, when a winning of a game ball is detected by the big winning port count switch 28 during the big hit game, a winning command is transmitted from the main control board 68 to the sub control board 70 based on this detection result. The sub-control board 70 controls the display of the number of counts (for example, “2C”, etc.) based on the received winning command, and controls the display modes (1) to (3) listed as effect information. I do. In the first embodiment, for example, the above-described count number display is performed in the upper right portion of the screen of the liquid crystal display 40, and the numerical display is controlled so as to sequentially change as the number of winning prizes increases. This is a general count number display and is not included in the “change the display mode of effect information” in the first embodiment.

  Thereby, the change of each display mode specifically becomes the following, for example.

  (1) In the display mode of FIG. 26, the symbols are shot down in order as the number of counts increases, and when the specified count number (for example, 10 counts) is reached, the symbol is represented by the last remaining symbol without being shot down. Promotion to a round is confirmed. However, if the symbol “2” is left last, it is not promoted after all.

  (2) In the display mode of FIG. 27, as the number of counts increases, the positions of the three-dimensional symbols are switched in order, and when the specified number of counts is reached, the round is finally represented by a symbol facing the front. Promotion to is confirmed. Similarly, if the symbol “2” faces the front, it will not be promoted.

  (3) In the display mode of FIG. 28, the positions of the symbols are sequentially switched as the count number increases, and when the specified count number is reached, the promotion to the round represented by the symbol positioned at the front is finally made. Is confirmed. It is the same as (1) and (2) above that the symbol “2” is not promoted when the symbol “2” is positioned at the front.

  In this way, in the first embodiment, it can be said that there is a device in the effect animation by the liquid crystal display 40 and the promotion effect animation itself for entertaining the player during the big hit game. Normally, the production of animation by this type of liquid crystal display is an effect that switches every time a predetermined time elapses using a production scheduler, whereas in the first embodiment, during the big hit game When the game ball that has entered the big prize opening 26 is detected by the big prize mouth count switch 28, the effect is switched. For this reason, it is not an effect of dressing up in advance, but an interesting effect linked to the progress of the game for the player.

  Also, in the promotion effect animations exemplified in the above (1) to (3), if the player wants to see each result quickly, the player appropriately sets the launch intensity (commonly referred to as “stroke”) of the game ball. Therefore, it becomes more interesting that it is necessary to make the game ball enter the big winning opening 26 as soon as possible, and the player is not bored.

(B. Notification of the result of the round)
However, there is a possibility that an adverse effect that the ending of the effect animation cannot be seen when the number of winnings per round is less than the prescribed number (10) only by this. In this regard, if there is no specified number of prizes in one round and the round is over (when the big prize opening 26 is closed for the 18th time), the sub-control board 70 adjusts the progress of the animation. The device has been devised to forcibly display the end of the promotion effect at the end of the round.

(C. Promotion reliability by display mode)
Here, in the first embodiment, the display modes (1) to (3) are listed as the images for promotion effects, but which mode appears may be promoted to a higher round ( It depends on the level of so-called reliability. Specifically, the above-described aspect (1) has a relatively low promotion reliability (or expectation), and the next aspect (2) has a relatively medium promotion reliability, and the last (3 ) Has a relatively high degree of reliability for promotion.

  It is left to the sub-control board 70 to determine in which display mode (1) to (3) the promotion effect is performed, and the sub-control board 70 has the lowest degree of reliability in promotion in the control of the promotion effect. (For example, when the real winning round is 2 rounds), the promotion effect can be controlled using the aspect of (1) above, and the reliability of promotion is moderate. When it can be determined (for example, when the real winning round is 7 rounds), the promotion effect can be controlled using the mode of (2) above. When the sub-control board 70 can be determined to have the highest degree of reliability of promotion (for example, when the real winning round is 15 rounds), the promotion effect can be controlled using the mode (3) above. it can.

  Thus, by changing the display mode for presentation according to the reliability of promotion (expectation of promotion to a higher round), it is possible to suggest the level of promotion possibility to the player. Further, the player can estimate the degree of reliability of promotion to some extent from the display mode at the time of promotion effect.

  29 and 30 show examples of images displayed on the liquid crystal display 40 as a result of the promotion effect. If two rounds are announced in the round lottery effect, and the first promotion effect is promoted to 7 rounds, the image shown in FIG. 29 is displayed, and if promoted to 15 rounds, the image shown in FIG. 30 is displayed. Is displayed. In these images, a symbol representing the number of rounds for which promotion has been established is displayed large in the center of the screen, and character information of “promotion” is displayed separately on both sides. Behind the pattern, a character imitating a police officer and a character imitating a person with a spear are lined up to show a comical expression. In accordance with the display of these images, sound information such as “promotion” is output from the speaker 88 in the voice color of each character, and a sound effect is output.

(8-5. Staging method)
When 7 rounds are notified by the above-mentioned round lottery effect or the first promotion effect, the promotion effect of whether the player is promoted to 7 rounds or 15 rounds during the sixth round jackpot game is performed. At this time, in the first embodiment, in order to increase the interest of the production, the possibility of promotion to the 15th round from the content of the production animation by the liquid crystal display 40 in the third, fourth, and fifth rounds is implied.

(8-6. Production information with script)
There are various ways of suggestion, but in the first embodiment, a series of performance animations displayed in 3 to 5 rounds is given a story, and the performance animation proceeds along the story. ing. In other words, the comical characters that appear in the production animation change destinations in various places (inside sewer pipes, fields (or rivers), in front of dispatch stations, on the chimney of the public bath, etc.) Entertaining players by taking various actions.

  As an example, a character imitating a thief appears in a production animation displayed in 3-5 rounds, and a character imitating a police officer is drawn while looking around while changing destinations. Also, in the production animation, the thief shows the gesture of escaping by carrying the symbol representing “15”, and the police officers are desperately searching to recover this. As a result, in the production animation, the thief's right to promote 15 rounds was stolen, so a story as if police officers were desperately searching to regain it. There are a variety of performance animation patterns displayed along the story at this time, but there is a certain relationship between the content of the story and the possibility of promotion. If it is a person, it is possible to guess a promotion possibility from the production animation displayed in 3-5 rounds.

  However, in the first embodiment, since there are 150 or more types of effect animation patterns displayed along the above-described story, it can be said that the implied method is slightly too complicated. For this reason, it is difficult for a player to feel the implied possibility of being promoted to 15 rounds from the contents of various production animations. Therefore, in the first embodiment, it is implied that the possibility of promotion increases as the character moves to a relatively high place in the production animation, and the possibility of promotion decreases as the character moves to a relatively low place. Techniques are further adopted.

  31 to 34 show examples of images displayed by the liquid crystal display 40 in the promotion effect of the sixth round. Here, the following four examples are given as display modes of the staging effect information.

  (1) A character imitating a police officer at the end of the fifth round enters the manhole underground, and the same character chases a thief while running inside the sewer pipe in the sixth round (FIG. 31). In this aspect, a state in which a symbol representing 7 rounds currently informed and a symbol representing 15 rounds after promotion run together in the sewer pipe together with the character are drawn.

  (2) When a character imitating a police officer runs up the bank at the end of the fifth round, a character imitating an infant appears in the sixth round, and the character runs on a tricycle and runs through the field (Kawara) (FIG. 32). In this aspect, a state in which a symbol representing 7 rounds currently informed and a symbol representing 15 rounds after promotion run along the field together with the character are drawn.

  (3) A mode in which a character imitating a police officer fades out with the screen at the end of the fifth round, and the same character moves in front of the dispatching station in the sixth round (FIG. 33). In this aspect, a state in which a symbol representing 7 rounds currently informed and a symbol representing 15 rounds after promotion drop from the head of the character and crush the character are drawn.

  (4) When a character imitating a police officer moves toward the public bath chimney at the end of the fifth round, a character imitating a person with a spear in the sixth round appears, and this character is at the top of the chimney. The mode which is paying off (FIG. 34). In this aspect, a state in which a symbol representing 7 rounds currently informed and a symbol representing 15 rounds after promotion appear and exit from the chimney are drawn.

  The aspect of (1) above implies that the destination of the character is relatively low, and thus the possibility of promotion is relatively low. On the contrary, the mode (4) implies that the destination of the character is relatively high, and in this case, the possibility of promotion is relatively high. In this way, by associating the big direction and the possibility of promotion in the story development of the production animation, it is possible to easily suggest the possibility of promotion to the player even if the production of the complex pattern is used it can. In other words, by such a device, it is possible to satisfy the conflicting demands of preventing the player from getting bored with a complicated performance and making it easier for the player to guess the possibility of promotion at a high level.

  Furthermore, the player may become bored of the game by simply determining the possibility of promotion based only on the destination and moving direction of the character. For this reason, even if it is a display mode that moves to a sewer pipe that has a low possibility of promotion, multiple patterns (commonly called “iron plate patterns”) that can be surely promoted depending on the destination or action after that are provided. Devised to draw out the player's inquisitive mind.

  FIG. 35 shows an example of a display mode corresponding to the “iron plate pattern”. In this display mode, the character imitating an infant is drawn happily wearing a tricycle against the background of the garden of a private house, and a pattern representing 15 rounds after promotion is displayed along with the character. be painted.

  FIG. 36 shows an example of an image displayed on the liquid crystal display 40 when the promotion to the 15th round is confirmed by the promotion effect of the 6th round. Here again, as in the promotion effect for the first round (FIG. 30), the symbol representing the 15th round after promotion is displayed in the center of the screen, and the character information of “promotion” is displayed on both sides. The The same applies to the point that audio information, sound effects, and the like are output from the speaker 88.

  The above is the contents of the promotion effect using a series of effect animations. However, there is naturally a case where an effect that is not promoted (seven rounds) is performed as a result. In this case, a symbol representing 7 rounds currently informed at the end of the promotion effect is displayed large on the screen, so that the player is informed easily that there has been no promotion.

  However, in the first embodiment, even if it is noticed that there was no promotion once, there is also an effect in which this result is overturned and the result of promotion to 15 rounds is notified again. This further enhances the appeal to players. In this case, an effect screen that is not promoted once is displayed, but after that, for example, a character imitating a police officer appears, and an effect of generating a strange voice (“Still More!” Etc.) with a motivated expression is performed. Then, the result of the promotion to 15 rounds will be notified again, so from the player's point of view, it seems as if the player who gave up the promotion once was revived and gained the promotion. As a result, there will be more direct entertainment.

(9. Second embodiment)
Next, a second embodiment that is distinguished from the first embodiment will be described.
In the second embodiment, the pachinko machine 1 used in the first embodiment can be applied as it is, but here the maximum number of rounds, the round lottery effect, and the effect display mode during the round operation are different. The differences between the first embodiment and the second embodiment are listed below.

  (1) In the first embodiment, the maximum number of rounds assigned by the main control board 68 is 15 rounds, but in the second embodiment, up to 16 rounds can be continued. However, this is merely a difference in game specifications and does not cause an essential difference in the invention.

  (2) In the first embodiment, when a big hit is made in the normal gaming state (when winning V), as shown in FIGS. 22 to 24, the number of rounds scheduled to be continued by round lottery ( 2 or 7, or 15) was reported, but in the second embodiment, the maximum number of rounds (the maximum number of rounds that can be continued in the gaming specifications) is always reported when a big hit is made, and it is scheduled to continue with it. The number of rounds is notified.

  The "maximum number of rounds" here is set in the game specifications, but there are multiple settings for the "maximum number of rounds", and the "maximum number of rounds" is determined by lottery at that time. The specification may be distributed. For example, by assigning the “maximum number of rounds” to 16 rounds in a big hit at one time, or to 10 rounds in another big hit, the value of the privilege given to the player for each big hit can be made different. it can. In addition, since the assist round number is determined by lottery within the range of the allocated “maximum round number” or less, for example, when the “maximum round number” is allocated to 16 rounds, the assist round number in that case is 16 Within the following range, it is distributed to 2, 7, 16 rounds, etc. Alternatively, when the “maximum number of rounds” is allocated to 10 rounds, the number of assist rounds in that case is allocated to, for example, 2, 7, 10 rounds within a range of 10 or less.

  In the first embodiment described above, since the player is not informed of the maximum number of rounds as a game specification, how far can the round operation be continued in one big hit game? The player may not be aware of this.

  Therefore, in the second embodiment, notification patterns 1 and 2 are provided that allow the player to always play the game after clearly recognizing the maximum number of rounds in the game specification. The aspect of the round notification in the second embodiment will be described below with a specific example.

(9-1. Notification pattern 1)
37 to 39 show examples of images used in the notification pattern 1 for the number of rounds. In the notification pattern 1, for example, character information “maximum continuation count” is displayed at the top of the screen, and subsequently, a symbol representing the maximum number of rounds “16” is displayed at the upper right position of the screen. Thus, the player can recognize that there is a possibility that the big hit game can be continued up to 16 rounds by one big hit game due to the gaming specifications of the pachinko machine 1.

  In addition, in the notification pattern 1, a symbol (for example, a design of the numbers “2”, “7”, “16” designed to represent the number of times of continuation) distributed in the round lottery is displayed in the center of the screen. The player can know the number of winning rounds (scheduled number of continuations) given to him from this symbol. Also, since the character information “Assist Round” is superimposed below each symbol “2”, “7”, “16”, the player can play the center up to the number of rounds represented by each symbol. It is possible to recognize that V winning is assisted in the accessory 6 (ball sorting member, ball stopping member, etc.), and that it is scheduled to continue.

  37 to 39, separate characters are displayed at the right positions of the symbols “2”, “7”, and “16” representing the number of assist rounds, and each character is classified according to the number of assist rounds. It is assigned in association.

  For example, in FIG. 37, a comical character imitating a small boy is displayed, and this character is drawn in an unfortunate expression for viewing. It can be said that such a character's facial expression expresses that it was an unfortunate lottery result, because the number of assist rounds was relatively small, only two, so the player received less profit.

  Also, in FIG. 38, a character imitating a kid with a pink suit and a bow tie is displayed, and this character is drawn with a smiling expression at first glance. In this case, the number of assist rounds is 7 and the fact that the result is a lottery that can receive a relatively moderate profit is expressed in a stunning manner.

  In FIG. 39, a character imitating a male student is displayed, and this character is drawn in a facial expression that makes a smile in a comical pose. In this case, since the number of assist rounds is 16 and the continuation is planned up to the maximum number of rounds, it is expressed stellarly that the lottery result is the highest profit.

  According to the notification pattern 1 described above, the player can correctly recognize the number of assist rounds together with the maximum number of rounds in the case of a big hit. For this reason, if the number of assist rounds is less than the maximum number of rounds (2 rounds or 7 rounds), the player can raise awareness towards continuing the round by technical intervention after the number of assist rounds has passed, If the same number of assist rounds as the maximum number of rounds is displayed, the player can feel great satisfaction in receiving the maximum profit from the round drawing.

(9-2. Notification pattern 2)
Next, FIGS. 40 to 43 show examples of images used in the notification pattern 2. In the notification pattern 2, when a big hit is made during a normal game, an effect image (see, for example, FIG. 20) is displayed and then the image shown in FIG. 40 is displayed, and thereafter, the images shown in FIGS. The displayed image is displayed.

  First, in FIG. 40, for example, character information “maximum number of continuations” is displayed at the top of the screen, and a symbol representing the maximum number of rounds “16” is displayed largely at the center of the screen below. Thereby, the player can first recognize that there is a possibility that the big hit game can be continued up to 16 rounds by one big hit game due to the gaming specifications of the pachinko machine 1. In FIG. 40, character information “Challenge Game !!” is displayed near the symbol representing the maximum number of rounds “16”, and character information “How long will it continue?” Is displayed below the symbol. It is displayed. For this reason, even if the player first recognizes the maximum number of rounds by contacting these character information, the player can additionally recognize that the continuation to the maximum number of rounds is not necessarily promised. .

  In addition, in the notification pattern 2, the images shown in FIGS. 41 to 43 are displayed after the image shown in FIG. 40. These images are scrolled in order except for the background image, and finally any one of them is displayed. One of the images may be stopped and displayed, or the image may be switched to any one of the images shown in FIGS. In these FIG. 41 to FIG. 43, symbols representing the number of assist rounds (designed by the numbers “2”, “7”, and “16”) are displayed large in the center of the screen, and the right position of each symbol is displayed. Are displayed corresponding types of characters (same type as the notification pattern 1). Note that the meaning of the facial expression of each character is the same as the notification pattern 1.

  In any case, when the image shown in FIGS. 41 to 43 is displayed after the image shown in FIG. 40, the player knows the winning round number (assist round number) given to him. be able to. Also, if the images shown in FIGS. 41 to 43 are scrolled as described above, the player can watch the images carefully in the hope that a better assist round will be given during that time. it can.

  According to the notification pattern 2, in the case of a big win, the player can clearly recognize the maximum number of rounds in the game specification first, and subsequently the number of assist rounds that he has obtained in the round lottery. Can be recognized correctly. Similarly in this case, if the number of assist rounds is less than the maximum number of rounds (2 rounds or 7 rounds), the awareness can be raised toward continuing the round by technical intervention after the number of assist rounds has passed, When the number of assist rounds equal to the maximum number of rounds is obtained, the player can feel a great satisfaction with the lottery result.

Further, the second embodiment has the following advantages in common with the notification patterns 1 and 2.
(1) With regard to the specifications of the pachinko machine 1 (the jackpot has the maximum number of rounds and assist rounds, etc.), the player can easily determine the maximum number of rounds based on the specifications and information magazines published by the manufacturer. Although it is possible to know, even if the player has not accessed such advance information, the number of assist rounds is notified together with the maximum number of rounds at the time of big hit, so the specifications of the pachinko machine 1 are correct. There is an advantage that it can be recognized. For this reason, even a player who did not know the specifications of the pachinko machine 1 in advance needs to know the necessary information without guessing the maximum number of rounds that can be continued empirically or asking the hall clerk. You can continue the big hit game smoothly.

  (2) In addition, since the maximum number of rounds is always notified at the time of big hit, even if a beginner who is unfamiliar with the game, the big hit game is compulsory (or automatically) when the assist round number given in the lottery is digested ) Will not have the wrong perception that it will end.

(9-3. Other patterns)
(1) In the second embodiment, the same “promotion effect” as in the first embodiment can be performed. For example, in the notification pattern 1, even if the assist round number is notified by the image shown in FIG. 37 or 38 at first, “2” or “7”, when the actual round operation is performed, 1 A mode in which the same promotion effect as in the case of the first embodiment is performed in the round or the sixth round may be used. Similarly, in the notification pattern 2, even if the assist round number is reported to be “2” or “7” by the image shown in FIG. 41 or FIG. 42 following the image shown in FIG. When the round operation is performed, a promotion effect similar to the case of the first embodiment may be performed in the first round or the sixth round.

  (2) Here, each character (shown in FIGS. 37, 38, and 39) is associated with the assist round numbers “2”, “7”, and “16”, respectively. By utilizing such characteristics, for example, by displaying any character in the image during an actual jackpot game (round action), the number of assist rounds given in this jackpot is always given to the player. It becomes possible to appeal.

  For example, as shown in FIG. 31 used in the first embodiment, character information (such as “6R”) indicating how many times the current round operation is during the big hit game, The winning count number (“6C” or the like) is displayed, but the number of assist rounds originally is not displayed as information. On the other hand, if the information on the assist round number is displayed on the screen during the big hit game and numerically displayed, there is a problem that the information given to the player is difficult to read at a glance.

  Therefore, in the second embodiment, by adding a character corresponding to each assist round number to the image during the big hit game, in addition to the current round number and winning count number, It can be easily recognized again. Specifically, when the character shown in FIG. 37 appears on the screen during the jackpot game, the player always recognizes that the number of assist rounds given in the jackpot game is “2”. Can do. Similarly, when the character shown in FIG. 38 appears, the number of assist rounds is “7”, and when the character shown in FIG. 39 appears, the number of assist rounds is “16”. Can recognize again.

  As a result, players will not have any doubts about how many rounds they will be assisted in the middle of the big hit game, and they will be able to tackle the big hit game with a feeling of comfort until they have exhausted all of the assist rounds. Yes, there is an advantage that when you approach the end of the assist round, you will be aware that the continuation of the round (challenge game) through technical intervention will begin, and you can change your feelings and tackle the game.

  Each character may be always displayed during the big hit game, or may be displayed at a specific timing or at an arbitrary timing. In any case, it is sufficient that the player can re-recognize the number of assist rounds by displaying the character.

  (3) On the other hand, if the original number of assist rounds is displayed in addition to the current number of rounds during a big hit game, the number of rounds that the player has continued on his own after the assist round is over is easy. There is an advantage that you can know.

  That is, the pachinko machine 1 is in a state in which the center continuation 6 assists the continuation of the round (V prize) during the assist round, but when the assist round is over, the state shifts to a state called “challenge game”. It is necessary to continue the round by technical intervention. At this time, if the player keeps repeating the round several times on his own, either the player in the game has a characteristic that is easy to win a V, or the player's technique is excellent. Is likely.

  In this case, if the above-mentioned character is used to display the assist round number, the original assist round number display is compared with the current round number display, and the number of rounds that the player has continued by himself is easy. There is an advantage that it is easy to understand that even if it is viewed objectively, the table in the game has the characteristic of easily winning V.

(10. Various control processes of the main control board)
Next, various control processes performed by the main control board 68 shown in FIG. 12 according to the progress of the game of the pachinko machine 1 will be described. First, various random numbers used for game control will be described, followed by power-on processing, timer interrupt processing, and specific area winning probability monitoring processing. 44 is a flowchart showing an example of the power-on process, FIG. 45 is a flowchart showing the continuation of the power-on process of FIG. 44, FIG. 46 is a flowchart showing an example of the timer interrupt process, and FIG. FIG. 48 is a flowchart showing an example of the specific area winning probability monitoring process. FIG. 48 shows initial values (a) set in the winning prize winning number storage buffer and the counting buffer, the winning prize winning number storing buffer and the count after initialization. It is a figure which shows the shift (c) of the shift (b) of a buffer, and the big winning opening winning number storage buffer and count buffer in the case of fraud. The specific area winning probability monitoring process is performed as one process of the fraud detection process in step S84 in a timer interrupt process to be described later.

(10-1. Various random numbers)
As various random numbers used for game control, a maximum round number setting random number, a maximum round number setting initial value update random number used for determining an initial value of the maximum round number setting random number, and the like are prepared.

(10-2. Power-on processing)
When the pachinko machine 1 is powered on, the MPU 68a, which is the microprocessor of the main control board 68, performs power-on processing as shown in FIGS. When the power-on process is started, the MPU 68a sets a stack pointer (step S10). The stack pointer indicates, for example, the address accumulated on the stack to temporarily store the contents of the memory element (register) in use, or temporarily returns the return address of this routine when returning to this routine after completing the subroutine. It indicates the address that is stacked on the stack for storage, and the stack pointer advances each time the stack is stacked. In step S10, an initial address is set in the stack pointer, and the contents of the register, the return address, etc. are stacked on the stack from this initial address. Then, the stack pointer returns to the initial address by sequentially reading from the last stacked stack to the first stacked stack.

  Subsequent to step S10, output of a power failure clear signal is started at the CLR terminal which is a clear terminal of a D-type flip-flop IC (not shown) of the main control board 68 (in this embodiment, manufactured by Tokyo Shibaura Electric: TC74HC74) (step S12). ). The power failure clear signal is input to the clear terminal CLR via the I / O port 68b of the main control board 68 with the logic being LOW. As a result, the MPU 68a can release the latch state of the D-type flip-flop IC, and the logic input to the PR terminal, which is the preset terminal of the D-type flip-flop IC, until the latch state described later is set. It can be inverted and output from the 1Q terminal, which is the output terminal, and the signal from the 1Q terminal can be monitored. A signal from a power failure monitoring circuit (not shown) of the main control board 68 is input to the PR terminal.

  Subsequent to step S12, wait timer processing 1 is performed (step S14), and it is determined whether or not a power failure warning signal is input (step S16). The voltage does not rise immediately from when the power is turned on until the voltage reaches the predetermined voltage. On the other hand, when there is a power failure or a momentary power failure (a phenomenon in which the supply of power is temporarily stopped), when the voltage drops and becomes smaller than the power failure warning voltage (reference voltage Vref), a power failure warning signal is input as a power failure warning from the power failure monitoring circuit. . Similarly, when the voltage becomes lower than the power failure warning voltage from when the power is turned on to when the voltage rises to a predetermined voltage, a power failure warning signal is input from the power failure monitoring circuit. Therefore, the wait timer process 1 in step S14 is a process for waiting after the power is turned on until the voltage becomes larger than the power failure warning voltage and stabilizes. In this embodiment, the wait timer process 200 waits for 200 milliseconds (wait timer) (wait timer). ms) is set. In step S16, it is determined whether or not the power failure notice signal is input. This determination is performed based on a signal output from the 1Q terminal, which is the output terminal of the D-type flip-flop IC, as a power failure warning signal.

  Subsequent to step S16, the output of the power failure clear signal is stopped at the CLR terminal which is the clear terminal of the D-type flip-flop IC (step S18). By stopping the output of the power failure clear signal, the logic becomes HI via the I / O port 68b and is input to the CLR terminal which is a clear terminal. As a result, the MPU 68a can set the D-type flip-flop IC in the latched state. When the D-type flip-flop IC latches the state where the logic is LOW and is input to the PR terminal which is the preset terminal, the D-type flip-flop IC outputs a power failure warning signal from the 1Q terminal which is the output terminal.

  Subsequent to step S18, it is determined whether or not the RAM clear switch 68c of the main control board 68 is operated (step S20). This determination is made based on whether or not the RAM clear switch 68c is operated and an operation signal (detection signal) is input to the MPU 68a. When the detection signal is input, it is determined that the RAM clear switch 68c is operated. On the other hand, when the detection signal is not input, it is determined that the RAM clear switch 68c is not operated.

  When the RAM clear switch 68c is operated in step S20, a value 1 is set to the RAM clear notification flag RCL-FLG (step S22). On the other hand, when the RAM clear switch 68c is not operated in step S20, the RAM clear is cleared. A value 0 is set in the notification flag RCL-FLG (step S24). This RAM clear notification flag RCL-FLG determines whether or not to erase game information relating to a game such as unpaid prize balls, which is stored in a RAM (hereinafter referred to as “built-in RAM”) built in the MPU 68a. And is set to a value of 1 when erasing game information and a value of 0 when not erasing game information. The RAM clear notification flag RCL-FLG set in step S22 and step S24 is stored in the general-purpose storage element (general-purpose register) of the MPU 68a.

  Subsequent to step S22 or step S24, wait timer processing 2 is performed (step S26). In this wait timer process 2, the system waits until the system for controlling the drawing of the liquid crystal display 40 by the liquid crystal control board 92 is started (booted) as shown in FIG. For example, various control programs compressed from a liquid crystal control ROM (not shown) of the liquid crystal control board 92 are read out and stored in a RAM built in a microprocessor (not shown) of the liquid crystal control board 92. In this embodiment, 2 seconds (s) is set as a time until booting (boot timer).

  Following step S26, it is determined whether or not the RAM clear notification flag RCL-FLG is 0 (step S28). As described above, the RAM clear notification flag RCL-FLG is set to a value of 1 when erasing game information and a value of 0 when not erasing game information. When the RAM clear notification flag RCL-FLG is 0 in step S28, that is, when the game information is not deleted, a checksum is calculated (step S30). This checksum is calculated by regarding the game information stored in the built-in RAM as a numerical value and calculating the sum.

  Subsequent to step S30, it is determined whether or not the calculated checksum value (sum value) matches a checksum value (sum value) stored in a power-off process (power-off) described later. (Step S32). If they match, it is determined whether or not the backup flag BK-FLG is 1 (step S34). The backup flag BK-FLG is a backup of game information, a checksum value (sum value), a backup flag BK-FLG value, a value of a winning prize winning number storage buffer DB, a value of a count buffer CB, etc., which will be described later. This is a flag indicating whether or not information is stored in the internal RAM in the power-off process described later. Value 1 when the power-off process is terminated normally, and value when the power-off process is not terminated normally Set to 0 respectively.

  When the backup flag BK-FLG has a value of 1 in step S34, that is, when the power-off process is normally completed, the work area of the built-in RAM is set as the time of power recovery (step S36). In this setting, in addition to setting the backup flag BK-FLG to 0, the power recovery time information is read from the ROM built in the MPU 68a (hereinafter referred to as “built-in ROM”), and this power recovery time information is stored. Set in RAM work area. Here, “at the time of power recovery” includes not only a state in which the power is turned off but also a state in which the power is turned on, and a state in which power is restored after a power failure or a momentary power failure.

  Subsequent to step S36, power-on command creation processing is performed (step S38). In the power-on command creation process, game information is read from the backup information, and various commands corresponding to the game information are stored in a predetermined storage area of the built-in RAM. For example, the values stored in the large winning opening winning number storage buffer DB (high winning opening winning number storing buffer DB [9] to large winning opening winning number storing buffer DB [0]) described later are also restored based on the backup information. Restored to

  On the other hand, when the RAM clear notification flag RCL-FLG is not 0 (value 1) in step S28, that is, when the game information is erased, or when the checksum value (sum value) does not match in step S32. Alternatively, when the backup flag BK-FLG is not a value 1 (value 0) in step S34, that is, when the power-off process is not normally terminated, the entire area of the built-in RAM is cleared (step S40). Specifically, the initial value (value 0) is written in the built-in RAM.

  Subsequent to step S40, a work area of the built-in RAM is set as an initial setting (step S42). In this setting, the initial information is read from the internal ROM, and this initial information is set in the work area of the internal RAM. For example, each time the opening / closing operation of the big prize opening 26 is performed once when a game ball enters the start opening 12, 12 or the start opening 14 shown in FIG. The initial value 0 is set in the counting buffer CB that counts and stores the number of game balls that have entered the winning opening 26, or from the normal game state to the start of the big hit game state, that is, from the normal game state. The initial value INI (this embodiment) is stored in the big prize winning number storage buffer DB that stores the value of the counting buffer CB that counts the number of game balls that have entered the big winning opening 26 until the V winning is stored as history information. Then, the value is 4, and a threshold value TH1 (value 40), which will be described later, is a value obtained by dividing the threshold value TH1 (value 40) by the number of arrays (10) in the big prize winning number storage buffer DB). (See FIG. 48 (a)). Note that the winning prize winning number storage buffer DB is configured as ten arrays of the winning prize winning number storage buffer DB [0] to the winning prize winning number storage buffer DB [9]. The value of the counting buffer CB that counts the number of game balls that have entered the grand prize opening 26 until winning the V prize is used as history information for ten times, and the prize winning number storage buffer DB [0] to the big prize is obtained. It is stored in the array of the winning prize storage buffer DB [9].

  Subsequent to step S42, RAM clear notification and test command creation processing is performed (step S44). In this RAM clear notification and test command creation processing, a RAM clear notification command for notifying the sub-control board 70 shown in FIG. A test command for performing an inspection is created and stored as transmission information in a transmission information storage area of the built-in RAM. When the sub control board 70 receives the RAM clear notification command, the RAM clear notification command is transmitted to the liquid crystal control board 92. On the other hand, when the sub control board 70 receives the test command, various inspections of the liquid crystal control board 92 are performed. A test command for execution is transmitted to the liquid crystal control board 92 and the like.

  Subsequent to step S38 or step S44, interrupt initialization is performed (step S46). This setting sets an interrupt cycle when timer interrupt processing described later is performed. In this embodiment, it is set to 4 ms.

  Subsequent to step S46, interrupt permission is set. (Step S48). With this setting, timer interrupt processing is repeatedly performed every interrupt cycle set in step S46, that is, every 4 ms.

  Subsequent to step S48, a value A is set in the watchdog timer clear register WCL (step S50). The watchdog timer is cleared by setting value A, value B and value C in this order in this watchdog timer clear register WCL.

  Following step S50, it is determined whether a power failure warning signal is input (step S52). This determination is performed based on a power failure warning signal from the power failure monitoring circuit of the main control board 68. When the power of the pachinko machine 1 is cut off or a power failure or a momentary power failure occurs, the voltage becomes lower than the power failure warning voltage (reference voltage Vref), and a power failure warning signal is input as a power failure warning from the power failure monitoring circuit.

  When no power failure warning signal is input in step S52, random number update processing 1 is performed (step S54). In this random number update process 1, the above-described maximum round number setting initial value update random number is updated. The initial value update random number for setting the maximum number of rounds is incremented (counted up) by 1 every time the random number update process 1 is performed, the range from the lower limit value to the upper limit value.

  Following step S54, the process returns to step S50 again to set the value A in the watchdog timer clear register WCL. In step S52, it is determined whether or not a power failure warning signal has been input. For example, the random number update process 1 is performed in step S54, and steps S50 to S54 are repeated. The processing from step S50 to step S54 is referred to as “main processing”. Since this main process is repeated while the timer interrupt process described later is not performed, the maximum round number setting initial random number is incremented in the random number updating process 1 in step S54, thereby increasing the maximum round number setting initial value. The value update random number is counted up at high speed.

  On the other hand, when a power failure warning signal is input in step S52, interrupt prohibition setting is performed (step S56). With this setting, timer interrupt processing, which will be described later, is not performed, writing to the built-in RAM is prevented, and rewriting of the game information, the value of the prize winning number storage buffer DB, the value of the counting buffer CB, and the like is protected.

  Subsequent to step S56, a power failure clear signal is output to the CLR terminal which is the clear terminal of the D-type flip-flop IC shown in FIG. 151 via the I / O port 68b, or the ball distribution shown in FIG. The drive signal output to the section motor 84, the special winning opening solenoid 82, etc. is stopped (step S58). When the power failure clear signal is output, the D-type flip-flop IC can release the latched state.

  Subsequent to step S58, a checksum is calculated and the calculated value is stored (step S60). The checksum is calculated by regarding the game information in the work area of the built-in RAM as a numerical value excluding the storage area for the checksum value (sum value) and the backup flag BK-FLG described above.

  Subsequent to step S60, the value 1 is set to the backup flag BK-FLG. (Step S62) This completes the storage of the backup information. Note that such backup is normally performed for game information, but in this embodiment, the value of the big prize winning number storage buffer DB and the value of the count buffer CB are also performed in conjunction with the game information. . This is because the special winning opening winning number storage buffer DB and the counting buffer CB are important parameters in the specific area winning probability monitoring process described later for determining whether or not the player is illegal.

  Subsequent to step S62, the watchdog timer is cleared (step S64). As described above, the clear setting is performed by sequentially setting the value A, the value B, and the value C in the watchdog timer clear register WCL.

  Following step S64, an infinite loop is entered. In this infinite loop, the value A, the value B, and the value C are not sequentially set in the watchdog timer clear register WCL, so that the watchdog timer is not cleared. Therefore, the MPU 68a is reset, and then the MPU 68a performs this power-on process again. The processing from step S56 to step S64 and the infinite loop are referred to as “power-off processing”.

  The pachinko machine 1 (MPU 68a) is reset when a power failure occurs or when an instantaneous power failure occurs, and the power-on process is performed by subsequent power recovery.

  In step S32, it is inspected whether the backup information stored in the built-in RAM is normal, and in step S34, it is inspected whether the power-off process has been normally completed. In this way, the backup information stored in the built-in RAM is checked twice to check whether the backup information is stored by fraud.

(10-3. Timer interrupt processing)
Next, timer interrupt processing will be described. This timer interrupt process is repeated at every interrupt period (4 ms in this embodiment) set in the power-on process shown in FIGS.

  When the timer interrupt process is started, the MPU 68a of the main control board 68 sets the value B in the watchdog timer clear register WCL (step S70). At this time, the value B is set in the watchdog timer clear register WCL following the value A set in step S50 of the power-on process (main process).

  Subsequent to step S70, the interrupt flag is cleared (step S72). By clearing the interrupt flag, the interrupt cycle is initialized, and the next interrupt cycle is counted from the initial value.

  Subsequent to step S72, switch input processing is performed (step S74). In this switch input process, various signals input to the input terminal of the I / O port 68b are read and stored as input information in the input information storage area of the built-in RAM. Specifically, detection from the big winning opening count switches 28, 28, the once starting opening switches 76, 76, the twice starting opening switch 78, the specific area switch 52, the other winning opening switch 80, etc. shown in FIG. A signal, an ACK signal from the payout control board 72 that informs that the payout control board 72 has successfully received a prize ball command transmitted in a prize ball control process, which will be described later, is read and stored as input information in the input information storage area. .

  Subsequent to step S74, timer subtraction processing is performed (step S76). In this timer subtraction process, for example, various commands transmitted by the main control board 68 (MPU 68a) during the time for which the big prize opening solenoid 82 shown in FIG. The time management of various times such as the ACK signal input determination time set as the determination condition is performed when determining whether or not the ACK signal indicating that the signal is normally received is input. Specifically, for example, when the ACK signal input determination time is set to 100 ms, every time this timer subtraction process is performed, the ACK signal input determination time is subtracted by 4 ms, and the subtraction result becomes 0. ACK signal input judgment time is accurately measured. These various times are stored as time management information in the time management information storage area of the built-in RAM.

  Subsequent to step S76, random number update processing 2 is performed (step S78). In this random number update process 2, the maximum round number setting random number and the maximum round number setting initial value updating random number described above are updated. This initial value update random number for setting the maximum number of rounds is also updated in the random number update process 1 of step S54 in the power-on process (main process) shown in FIG. The MPU 68a of the main control board 68 counts up the range from the lower limit value of the maximum round number setting initial value update random number to the upper limit value every time this timer interrupt process is performed. Specifically, by counting up from the initial value of the initial value update random number for maximum round number setting to its upper limit value, and counting up from the lower limit value of the initial value update random number for maximum round number setting to its initial value, The random number for setting the maximum number of rounds is counted up from the lower limit of the initial value update random number for setting the maximum number of rounds to the upper limit. When this count-up is completed, the initial value update random number for setting the maximum number of rounds updated in the random number update process 2 is used as an initial value again, and the maximum number of rounds setting random number is set to the lower limit of the initial value update random number for setting the maximum number of rounds. To the upper limit value. In this way, the initial value update random number for setting the maximum number of rounds is updated in the main process and the timer interrupt process, thereby improving the randomness.

  Subsequent to step S78, prize ball control processing is performed (step S80). In this prize ball control process, the input information is read from the above-mentioned input information storage area and a prize ball command for paying out a game ball is created based on this input information, or the board of the main control board 68 and the payout control board 72 Or create a self-check command to check the connection status. Then, the created prize ball command or self-check command is transmitted to the payout control board 72. For example, when one game ball enters the big winning opening 26, a prize ball command for paying out 10 balls as a prize ball is created and transmitted to the payout control board 72, or the prize ball command is sent to the payout control board 72. When a payer ACK signal indicating that the reception has been completed successfully is not input within a predetermined time, a payout control board is created by creating a self-check command for checking the connection state between the main control board 68 and the payout control board 72. 72.

  Subsequent to step S80, frame command reception processing is performed (step S82). The payout control board 72 transmits, for example, a status command such as a state in which a prize ball unit (not shown) that pays out a game ball to the player causes the ball to bend and the game ball cannot be paid out. In the frame command reception process of step S82, when this status command is normally received, information to that effect is sent to the payout control board 72 and stored as output information in the output information storage area of the built-in RAM. Further, the normally received status command is shaped and stored as transmission information in the transmission information storage area described above.

  Subsequent to step S82, fraud detection processing is performed (step S84). In this fraud detection process, the abnormal state related to the prize ball is confirmed. For example, the input information is read from the above-described input information storage area, and whether or not the detection signal from the big winning port count switches 28 and 28 is inputted when not in the big win gaming state (when the big winning game port 26 is not in the big hit gaming state). Whether or not a game ball has entered the game), or reading the large winning opening winning number storage buffer DB stored in the internal RAM, and confirming the history of the number of game balls that have entered the V prize. Or If the player has illegally acquired a game ball by this confirmation, a prize ball abnormality notification command is created as an abnormal state and stored as transmission information in the transmission information storage area described above.

  Subsequent to step S84, game processing is performed (step S86). In this game process, various game settings are made in order to read the input information from the above-described input information storage area and advance the game according to the various timing charts shown in FIGS. For example, it is determined whether or not the maximum round number setting random number matches any of the 2 round determination value, the 7 round determination value, and the 15 round determination value stored in the built-in ROM in advance. A game effect command is transmitted to notify the fact that the player has won the 1st start prize opening 12, 12, the 2nd start prize opening, the grand prize winning opening 26 and the V winning prize, and stores the transmission information described above as transmission information. When the game is stored in the area, or when winning a V and shifting from the normal gaming state to the big hit gaming state, the output of the driving signal to the big winning opening solenoid 82 is set so as to open and close the movable piece 24, and the output information is described above. Or stored in an output information storage area.

  Subsequent to step S86, port output processing is performed (step S88). In this port output processing, output information is read from the output information storage area described above from the output terminal of the I / O port 68b, and various signals are output based on this output information. For example, when the status command from the payout control board 72 is normally received from the output terminal based on the output information, the main payout ACK signal is output to the payout control board 72, or when it is in the big hit gaming state, Is output to the big winning opening solenoid 82 that opens 26, or a big hit information output signal that tells that a big hit gaming state has occurred, the game ball is in the start port 12, 12 once or the start port 14 twice Various information (game information) related to the game, such as a start opening prize information output signal that conveys the fact that the player has entered, and an unauthorized information output signal that informs that the player has illegally acquired the game ball, are provided via the payout control board 72. To the external terminal board 73. The external terminal board 73 is electrically connected to a hall computer (not shown) that supervises and manages pachinko machines installed in the hall, and the hall computer monitors the gaming state of the pachinko machine.

  Subsequent to step S88, sub-control board command transmission processing is performed (step S90). In the sub-control board command transmission process, the transmission information is read from the transmission information storage area described above, and the transmission information is transmitted to the sub-control board 70. As described above, the transmission information includes a game effect command, a RAM clear notification command, a test command, a prize ball abnormality notification command, a status command, and the like. In addition to transmitting this transmission information, there is a problem in the connection state based on the value of the self-check flag set when the connection state between the main control board 68 and the payout control board 72 is confirmed. Sometimes a connection failure command is created and transmitted to the sub-control board 70.

  Subsequent to step S90, the value C is set in the watchdog timer clear register WCL (step S92). By setting the value C in the watchdog timer clear register WCL in step S92, the value C is set in the watchdog timer clear register WCL following the value B set in step S70. As a result, the value A, the value B, and the value C are sequentially set in the watchdog timer clear register WCL, and the watchdog timer is cleared.

  Subsequent to step S92, the register is switched (returned) (step S94), and this routine is terminated. Here, when this timer interrupt process is started, the MPU 68a loads and saves the contents of the general-purpose register on the stack in hardware. This prevents the contents of the general-purpose register used in the main process from being destroyed. In step S96, the contents saved on the stack are read and written to the original register. The MPU 68a sets the interrupt permission after the return in step S96.

(10-4. Specific area winning probability monitoring process)
Next, the specific area winning probability monitoring process will be described. In the specific area winning probability monitoring process, the game ball that has entered the big winning opening 26 falls through the high probability path 38 to the stage 46c of the ball sorting member 46, and the dropped gaming ball is used as the specific winning opening guide section. 46a, in order to make it accept to 46a, it removes the cut part connected to specific prize mouth guide part 46a among the cut parts of four partition 46d formed in the circumference of stage 46c, that is, it leads to general prize mouth guide part 46b 3 This is a process for determining whether or not an illegal act of covering all the cut portions with a cover or the like is performed. When a game ball that has entered the grand prize winning opening 26 by such a fraudulent activity is sent to the high probability path 38 by the ball path changing member 34, the game ball is forcibly specified through the high probability path 38. It will be accepted by the winning opening guide 46a, and it is always possible to win V.

  When the specific area winning probability monitoring process is started, the MPU 68a of the main control board 68 determines whether or not it is a big hit gaming state as shown in FIG. 47 (step S100). When it is not the big hit gaming state in step S100, it is determined whether or not the output setting of the drive signal to the big winning opening solenoid 82 is performed (step S102). In this determination, the output information is read from the output information storage area described above, and the determination is made based on the output information. Specifically, it is determined whether or not information for outputting a drive signal to the special winning opening solenoid 82 that opens the special winning opening 26 is set in the output information.

  When the output of the drive signal to the big prize opening solenoid 82 is set in step S102, that is, when the information for outputting the driving signal to the big prize opening solenoid 82 that opens the big prize opening 26 is set as the output information. Then, it is determined whether or not there is a detection signal from the special winning opening count switches 28, 28 (step S104). In this determination, input information is read from the above-described input information storage area, and the determination is made based on this input information. Specifically, it is determined whether or not the detection signals from the special winning opening count switches 28 and 28 are input to the input terminal of the I / O port 68b.

  When there is a detection signal from the big winning count switch 28, 28 in step S104, that is, when the detection signal from the big winning count switch 28, 28 is inputted to the input terminal of the I / O port 68b, the counting buffer. The value 1 is added to CB (increment, step S106). The counting buffer CB is used to count the number of game balls that have entered the grand prize opening 26. Each time the entered game ball is detected by the big prize port count switches 28, 28, the value 1 is counted. Is added.

  On the other hand, when there is no detection signal from the big prize opening count switches 28, 28 in step 104, that is, when the detection signal from the big prize opening count switches 28, 28 is not inputted to the input terminal of the I / O port 68b. Or, following step S106, it is determined whether or not there is a detection signal from the specific area switch 52 (step S108). In this determination, the input information is read from the input information storage area and is performed based on the input information. Specifically, it is determined whether or not the detection signal from the specific area switch 52 has been input to the input terminal of the I / O port 68b.

  When there is a detection signal from the specific area switch 52 in step S108, that is, when the detection signal from the specific area switch 52 is input to the input terminal of the I / O port 68b, the big winning opening winning number storage buffer processing is performed. (Step S110). In the big prize winning number storage buffer process, the big prize winning number storage buffer DB is shifted. Specifically, the value of the big winning mouth winning number storage buffer DB [8] is shifted to the big winning mouth winning number storage buffer DB [9], and the big winning mouth prize winning buffer DB [8] is shifted to the big winning mouth winning number storage buffer DB [8]. The value of the number storage buffer DB [7] is shifted,..., The value of the big prize winning number storage buffer DB [0] is shifted to the big winning prize winning number storage buffer DB [1], and the big winning prize winning is achieved. The value of the count buffer CB described above is set in the number storage buffer DB [0]. Then, the initial value 0 is set in the counting buffer CB. As described above, the large winning opening winning number storage buffer process is performed when the detection signal from the specific area switch 52 is input to the input terminal of the I / O port 68b. In other words, it is performed when winning a V and shifting to the big hit gaming state. As a result, the arrangement of the winning prize winning number storage buffer DB [0] to the winning prize winning number storage buffer DB [9] is arranged from the normal gaming state to the start of the big hit gaming state, that is, the normal gaming state. The number of game balls that have entered the big prize opening 26 from V to V is stored.

  Subsequent to step S110, the sum value SV of the big prize winning number storage buffer DB is calculated (step S112). Here, the values of the winning prize winning number storage buffer DB [9] to the winning prize winning number storing buffer DB [0] shifted in step S110 are extracted, and all the extracted values are added to obtain the sum value SV. Is calculated.

  Following step S112, it is determined whether or not the calculated sum value SV is smaller than the threshold value TH1 (step S114). This threshold value TH1 is the number of winning prizes when the initial value INI is stored in 10 arrays of the winning prize winning number storage buffer DB [0] to the winning prize winning number storing buffer DB [9]. The sum value of the storage buffer DB is 40 (= initial value INI (value 4) × 10 times). In the present embodiment, a game ball that has entered the big winning opening 26 is sent to either the low probability path 36 or the high probability path 38 by the ball path changing member 34 and received by the ball sorting member 46. . As described above, in the ball distribution member 46, one of the eight U-shaped notches formed at equal intervals in the circumferential direction is the specific winning opening guide 46a, and the other (seven ) Are all general prize opening guides 46b. Further, as described above, one of the cut portions between the four partition walls 46d formed around the stage 46c is connected to the specific winning opening guide portion 46a on the upper surface of the ball sorting member 46, and the others. The (three) cut portions are connected to the general winning opening guide 46b. When the game ball sent to the low probability path 36 by the ball path changing member 34 is received by the ball sorting member 46, the game ball enters the specific winning opening guide 46a with a probability of 1/8, that is, V wins. There is a possibility that when the game ball sent to the high probability path 38 by the ball path changing member 34 is received by the ball sorting member 46, the game ball enters the specific winning opening guide 46a with a quarter probability. In other words, there is a possibility of winning V. Here, for example, out of the cut portions between the four partition walls 46d formed around the stage 46c, the cut portion connected to the specific winning port guide portion 46a is excluded, that is, three cut portions connected to the general winning port guide portion 46b. If an illegal act of covering all with a lid or the like is performed, the game ball sent to the high probability path 38 by the ball path changing member 34 is reduced by a quarter when received by the ball sorting member 46. The game balls do not enter the specific winning opening guide section 46a with a probability, but all the game balls enter the specific winning opening guide section 46a and win V, so that the normal gaming state shifts to the big hit gaming state. In this case, the arrangement of the winning prize winning number storage buffer DB [0] to the winning prize winning number storage buffer DB [9] is from the normal gaming state to the start of the big hit gaming state, that is, the normal gaming state. Since the number of game balls that have entered the big prize opening 26 from the time of winning to the V winning is stored, any value from 1 to 4 is stored. Become. Then, when an illegal act is performed, the sum value of the values stored in the ten arrays of the big prize winning number storage buffer DB [0] to the big prize winning number storage buffer DB [9] is calculated. Then, the calculated value becomes smaller than the value 40 (in FIG. 48C, the sum value SV becomes the value 29). Therefore, in the present embodiment, the number of game balls that have entered the big prize opening 26 from the normal game state to the V prize is stored as a history, and the number of game balls is monitored, so that Of the cuts between the four partition walls 46d formed around the stage 46c, except for the cut connected to the specific winning opening guide 46a, that is, to all three cuts connected to the general winning opening guide 46b. It is determined whether an illegal act of covering with a lid or the like is being performed.

  When the thumb value SV calculated in step S114 is smaller than the threshold value TH1, that is, when an illegal act is performed in which the general winning opening guide 46b of the ball sorting member 46 is closed with a lid or the like, a probability abnormality notification setting process is performed. (Step S116), and this routine is finished. In this probability abnormality notification setting process, in order to notify the store clerk or the like that an illegal act is being performed, a lighting signal or a blinking signal number for the decoration lamp 2a is set, and the output information storage area described above as output information Or a prize ball abnormality notification command is created as an abnormal state and stored in the transmission information storage area described above as transmission information.

  On the other hand, when it is a big hit gaming state at step S100, or when the output setting of the drive signal to the big prize opening solenoid 82 is not set at step S102, that is, the driving signal to the big prize opening solenoid 82 that opens the big prize opening 26. Is not set in the output information, or when the sum value SV calculated in step S114 is greater than or equal to the threshold value TH1, that is, all three cuts connected to the general winning opening guide 46b are covered with lids, etc. This routine is finished as it is when an illegal act of covering with a cover is not performed. Note that the proportion of game balls that entered the big prize opening 26 in a timely manner depends on the position of the nail arranged near the big prize opening 26, so in this embodiment, a prototype was produced. By actually making a test shot of the pachinko machine 1, the above-described threshold value TH1 is set to an appropriate value.

  According to the pachinko machine 1 of the present embodiment described above, the main control board 68, the center accessory 6, and the ball sorting member 46 are provided. The main control board 68 is mounted with an MPU 68a which is a microprocessor for controlling the progress of the game. The center accessory 6 is arranged at substantially the center of the game area, and the game ball launched into the game area can enter the big winning opening 26 when the movable piece 24 is operated. The ball allocating member 46 is provided in the center accessory 6 and distributes the game balls that have entered the center accessory 6 to a specific winning port 60 that is a specific region or a general winning port 50 that is a non-specific region. ing.

  The center accessory 6 further includes special winning opening count switches 28 and 28 and a specific area switch 52. The big winning opening count switches 28, 28 detect a game ball that has entered the center accessory 6 (large winning opening 26). The specific area switch 52 is a game ball in which a game ball that has entered the center accessory 6 (large winning opening 26) has entered the specific winning opening 60 by the ball sorting member 46 (the game ball falling to the specific winning opening 60) ) Is detected.

  The MPU 68a, which is a microprocessor mounted on the main control board 68, has various types of games in order to proceed in accordance with the various timing charts shown in FIGS. Perform game settings. For example, it is determined whether or not the maximum round number setting random number matches any of the 2 round determination value, the 7 round determination value, and the 15 round determination value stored in the built-in ROM in advance. A game effect command is transmitted to notify the fact that the player has won the 1st start prize opening 12, 12, the 2nd start prize opening, the grand prize winning opening 26 and the V winning prize, and stores the transmission information described above as transmission information. When the game is stored in the area, or when winning a V and shifting from the normal gaming state to the big hit gaming state, the output of the driving signal to the big winning opening solenoid 82 is set so as to open and close the movable piece 24, and the output information is described above. Or stored in an output information storage area.

  Subsequently, the MPU 68a adds 1 to the count buffer CB in the process of step S106 in the specific area winning probability monitoring process of FIG. The counting buffer CB is used to count the number of game balls that have entered the grand prize opening 26. Each time the entered game ball is detected by the big prize port count switches 28, 28, the value 1 is counted. Is added.

  Subsequently, the MPU 68a performs a shift process of the big prize winning number storage buffer DB in the big prize winning number storage buffer process of step S110 in the specific area winning probability monitoring process of FIG. Specifically, as described above, the value of the big prize winning prize storage buffer DB [8] is shifted to the big winning prize winning number storage buffer DB [9], and the big winning prize winning number storage buffer DB [8] is shifted. The value of the winning prize winning number storage buffer DB [7] is shifted to ..., and the value of the winning prize winning number storage buffer DB [0] is shifted to the winning prize winning number storage buffer DB [1]. Then, the value of the counting buffer CB is set in the large winning opening winning number storage buffer DB [0]. Then, the initial value 0 is set in the counting buffer CB. As described above, the large winning opening winning number storage buffer process is performed when the detection signal from the specific area switch 52 is input to the input terminal of the I / O port 68b. In other words, it is performed when winning a V and shifting to the big hit gaming state. As a result, the arrangement of the winning prize winning number storage buffer DB [0] to the winning prize winning number storage buffer DB [9] is arranged from the normal gaming state to the start of the big hit gaming state, that is, the normal gaming state. The number of game balls that have entered the big prize opening 26 from V to V is stored.

  Subsequently, in the process of step S112 in the specific area winning probability monitoring process of FIG. 47, the MPU 68a shifts the winning prize winning number storage buffer DB [9] to the winning prize winning number storage buffer DB [0] shifted in step S110. The sum value SV is extracted, and all the extracted values are added to calculate the sum value SV.

  Subsequently, the MPU 68a determines whether or not the sum value SV calculated in step S112 is smaller than the threshold value TH1 in the determination process of step S114 in the specific area winning probability monitoring process of FIG. This threshold value TH1 is the number of winning prizes when the initial value INI is stored in 10 arrays of the winning prize winning number storage buffer DB [0] to the winning prize winning number storing buffer DB [9]. The sum value of the storage buffer DB is 40 (= initial value INI (value 4) × 10 times).

  Subsequently, when the thumb value SV calculated in step S114 is smaller than the threshold value TH1, that is, when an illegal act of closing the general winning opening guide portion 46b of the ball sorting member 46 with a lid or the like is being performed, the MPU 68a The probability abnormality notification setting process of step S116 in the 47 specific area winning probability monitoring process is performed. In order to notify the hall clerk or the like that an illegal act is being performed, a lighting signal or blinking signal number is set to the decorative lamp 2a, and the sum value SV calculated in step S114 is equal to or greater than a threshold value TH1. 47, that is, when an illegal act of covering all three cuts connected to the general winning opening guide 46b with a cover or the like is not performed, the specific area winning probability monitoring process of FIG. 47 is terminated and the gaming state is changed. Is maintained.

  Here, for example, a fraudulent act (specifically, the stage 46c of the ball sorting member 46 of the ball sorting member 46) that distributes all game balls that have entered the center role 6 (large winning opening 26) to the specific winning opening 60 that is a specific area. Cover all three cut portions connected to the general winning opening guide portion 46b except for the cut portion connected to the specific winning opening guide portion 46a among the cut portions of the four partition walls 46d formed in the periphery. In the case where a fraudulent act is performed, the period of transition from the normal gaming state to the special gaming state in which a profit is given to the player is extremely short. Accordingly, the number of game balls that have entered during the transition from the normal gaming state to the special gaming state is used as a history to receive the winning prize winning number storage buffer DB [0] to the winning prize winning number storage buffer DB [9]. Is stored in this arrangement, and the winning prize winning number storage buffer DB DB which is the latest history based on the history stored in the winning prize winning number storing buffer DB [0] to the winning prize winning number storing buffer DB [9]. The value of the big winning mouth winning number storage buffer DB [9], which is a history that goes back 10 times from [0], is extracted, and all the extracted values are added to calculate the sum value SV. Can be determined whether or not the player has acquired a large amount of illegal game balls. Therefore, it is possible to prevent a large amount of game balls from being acquired due to a player's fraud.

  Further, when a power failure or a momentary power failure occurs, the MPU 68a which is a microprocessor mounted on the main control board 68 is stored in the built-in RAM in the power-off process in steps S56 to S64 in the power-on process in FIG. Back up the information you have. Then, when recovering from a power failure or a momentary power failure, in the power-on command creation process in step S38 in the power-on process of FIG. 45, the recovery is performed based on the information stored in the internal RAM backed up in the power-off process. . As a result, the values stored in the big prize winning number storage buffer DB [9] to the big winning number winning number storage buffer DB [0] are also restored to the original values. As described above, when recovering from a power failure or a momentary power failure, the winning prize winning number storage buffer DB [9] to the winning prize winning number storage buffer DB [0] are promptly based on the information stored in the internal RAM. ] Is restored to the original value, so that the player can start the game after the recovery.

  Furthermore, the MPU 68a, which is a microprocessor mounted on the main control board 68, determines whether or not the RAM clear switch 68c is operated in the determination process of step S20 in the power-on process of FIG. If it is determined that 68c is operated, in the process of step S42 in the power-on process of FIG. 45, the initial information is read from the internal ROM and this initial information is set in the work area of the internal RAM. For example, as described above, the opening / closing operation of the grand prize opening 26 is performed once when the game ball enters the start port 12, 12 or the start port 14 shown in FIG. Every time, the initial value 0 is set in the counting buffer CB that counts and stores the number of game balls that have entered the big winning opening 26, or until the big hit game state is started from the normal game state, In other words, the initial value is stored in the big prize winning number storage buffer DB that stores the value of the counting buffer CB that counts the number of game balls that have entered the big prize opening 26 from the normal gaming state until the V winning is stored as history information. INI (value 4 in this embodiment) is set. For this reason, when the RAM clear switch 68c is operated, all the history stored in the built-in RAM is cleared and the value 0 is overwritten (initialized) as an initial value, but the initial value INI ( Value 4 = value obtained by dividing the threshold value TH1 (value 40) by the number of arrays (10) in the big prize winning number storage buffer DB) is overwritten as an initial value. As a result, the MPU 68a, in the process of step S112 in the specific area winning probability monitoring process of FIG. 47, receives the winning prize winning number storage buffer DB [9] to the winning prize winning number storage buffer DB [0] shifted in step S110. ], And the sum value SV calculated by adding all of the extracted values becomes the threshold value TH1, so that the MPU 68a can execute the identification shown in FIG. 47 even if the RAM clear switch 68c is operated. In the determination process of step S114 in the area winning probability monitoring process, it is not determined that the sum value SV calculated in step S112 is smaller than the threshold value TH1. Therefore, even if the RAM clear switch 68c is operated, it is possible to prevent erroneous determination that an illegal act by the player is being performed by the determination process in step S114. As a result, even if some trouble occurs in the pachinko machine 1 and a store clerk or the like of the hall is forced to operate the RAM clear switch 68c, it happens that the player has started playing after the RAM clear switch 68c is operated. Even if a game ball wins a V, it will not be reported as an illegal act, so it will not be seen by other players or hall clerk, etc. .

(11. Other examples)
It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be implemented in various modes as long as it belongs to the technical scope of the present invention.

  For example, in the above-described embodiment, the values stored in the ten arrays of the winning prize winning number storage buffer DB [0] to the winning prize winning number storage buffer DB [9] are respectively extracted, and the extracted values are extracted. The sum is calculated by comparing the calculated value with the threshold value TH1, and is stored in the winning prize winning number storage buffer DB [0] to the winning prize winning number storage buffer DB [9]. A moving average may be calculated based on the obtained value and compared with the threshold value TH2. Here, the moving average is calculated by extracting values stored in 10 arrays from the winning prize winning number storage buffer DB [0] to the winning prize winning number storing buffer DB [9], respectively. It can be calculated by dividing the sum total of the values by the number of arrays in the big prize winning number storage buffer DB. The threshold value TH2 is set to a value 4, which is the same value as the initial value INI. This is because, as described above, the game ball that has entered the big prize opening 26 is sent to either the low probability path 36 or the high probability path 38 by the ball path changing member 34 and received by the ball sorting member 46. It has become. In the ball distribution member 46, one of the eight U-shaped notches formed at equal intervals in the circumferential direction is a specific winning opening guide portion 46a, and the other (seven) notches are all. It is a general winning opening guide 46b. In addition, on the upper surface of the ball sorting member 46, one cut portion of the cut portions of the four partition walls 46d formed around the stage 46c is connected to the specific winning opening guide portion 46a, and the other (three). The cut portion is connected to the general winning opening guide 46b. When the game ball sent to the low probability path 36 by the ball path changing member 34 is received by the ball sorting member 46, the game ball enters the specific winning opening guide 46a with a probability of 1/8, that is, V wins. There is a possibility that when the game ball sent to the high probability path 38 by the ball path changing member 34 is received by the ball sorting member 46, the game ball enters the specific winning opening guide 46a with a quarter probability. In other words, there is a possibility of winning V. Here, for example, out of the cut portions between the four partition walls 46d formed around the stage 46c, the cut portion connected to the specific winning port guide portion 46a is excluded, that is, three cut portions connected to the general winning port guide portion 46b. If an illegal act of covering all with a lid or the like is performed, the game ball sent to the high probability path 38 by the ball path changing member 34 is reduced by a quarter when received by the ball sorting member 46. The game balls do not enter the specific winning opening guide section 46a with a probability, but all the game balls enter the specific winning opening guide section 46a and win V, so that the normal gaming state shifts to the big hit gaming state. In this case, the arrangement of the winning prize winning number storage buffer DB [0] to the winning prize winning number storage buffer DB [9] is from the normal gaming state to the start of the big hit gaming state, that is, the normal gaming state. Since the number of game balls that have entered the big prize opening 26 from the time of winning to the V winning is stored, any value from 1 to 4 is stored. Become. Therefore, when determining whether or not the player is performing an illegal act of acquiring a large amount of illegal game balls, the prize winning number winning buffer storage buffer DB [0] to the prize winning prize winning number storing buffer DB When determining the presence or absence of the fraud using the moving average based on the value stored in [9], for example, when the calculated moving average value is 3.9, the threshold value TH2 is set. Since it is smaller than the set value 4, it can be determined that the player is performing an illegal act of acquiring a large amount of illegal game balls.

  In the above-described embodiment, when the RAM clear switch 68c is operated, the initial value INI, which is a fixed value, is stored in the big prize winning prize storage buffer DB [0] to the big winning prize winning prize storage buffer DB [9]. Each is set, but it may be changed to an initial value INI. For example, since the player may start playing after the RAM clear switch 68c is operated, the game ball may win V, so that the big winning opening 26 is changed from the normal game state to the big hit game state. The number of game balls that have entered the field is the value 4, value 8, value 10,..., Value 40, value 40, value 40, etc., and the initial value INI is set a predetermined number of times since the RAM clear switch 68c is operated. Let it fluctuate and then set it to a fixed value. In the case where the initial value INI is changed by such a predetermined number of times, it is necessary to set each value to be changed to an appropriate value by actually making a trial hit of the prototype pachinko machine 1.

  Furthermore, in the above-described embodiment, the MPU 68a, which is a microprocessor mounted on the main control board 68, determines whether or not the RAM clear switch 68c is operated in the determination process of step S20 in the power-on process of FIG. If it is determined that the RAM clear switch 68c has been operated, the initial information is read from the built-in ROM and set in the work area of the built-in RAM in the process of step S42 in the power-on process of FIG. However, at this time, it may be performed only for information other than the prize winning number storage buffer DB [0] to the prize winning number storage buffer DB [9] stored in the built-in RAM. That is, when the RAM clear switch 68c is operated, the initial value INI is not set in the large winning opening winning number storing buffer DB [0] to the large winning opening winning number storing buffer DB [9], and is directly stored in the built-in RAM. The stored value may be retained. In this way, the value of the winning prize winning number storage buffer DB [0] to the winning prize winning number storage buffer DB [9] can be held regardless of whether or not the RAM clear switch 68c is operated. Even after the operation of the clear switch 68c, it is possible to continuously monitor whether or not the player is illegal.
