Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a variable display device and an auxiliary variable display device, and when the game state becomes a preset game state, a prize mode is generated in the variable display device and the auxiliary variable display device. Regarding pachinko machines whose probabilities are changed.

[0002]

2. Description of the Related Art Conventionally, in order to enhance the enjoyment of a game, a variable winning device is advantageous to a player when, for example, a variable display device brings "7", "7" and "7" into a special game state. There is a so-called first type of pachinko machine configured to change to a state. In addition, in order to enhance the enjoyment of the game, for example, when a special display state such as "7", "7", and "7" is displayed on the variable display device, a special right occurs and a special winning opening is awarded. There is also a so-called third type of pachinko machine in which the variable winning device is repeatedly converted into an advantageous state for the player.

And, in these pachinko machines,
The probability of the variable display device is fixed, or even if it can be changed, it can only be changed uniformly by an external setting device or the like. Further, in the above-mentioned pachinko machine, when the movable member of the variable winning device converts the hit ball into a state in which it is easy to win the ball in a specific state, the movable member causes the obstacle nail to win the hit ball to another winning port. In many cases, it is adjusted so as to be bent so as to induce a so-called bonus prize in a specific game state, and such adjustment enhances the enjoyment of the game.

[0004]

However, inducing a bonus prize by bending an obstacle nail extremely is different from the game expected when the pachinko machine was designed, and is recognized as a healthy game. hard. Also, in pachinko machines that can change the probability of the variable display device by setting external devices, etc., keep the probability of the variable display device unknown to the player.
It is set so that it can be changed to / 1000, 1/500, 1/250, 1/100, etc., but once the player starts playing, which pachinko machine has the highest setting probability, which pachinko As a result, it is easy to judge whether the machine has a bad setting probability, which results in a difference from the business policy intended by the game store. For this reason, the player does not try to play on a pachinko machine with a low probability of setting, and only the pachinko machine with a high probability of setting results in playing a game, and the profit balance between the game store and the player is lost.

Therefore, the balance between the operating profit of the game store and the profit earned by the player is maintained, and the interest of the player can be enhanced without using any means such as unreasonably bending the obstacle nail. It has been desired to develop a pachinko machine that allows a player to enjoy the game in a healthy manner, in addition to the highly predictable game whether or not the specific game occurs even during the normal game.

Further, a display portion 51 for displaying the rotating state of the switching member 45 is formed on the front surface of the switching member 45, and a display window 52 facing the display portion 51 is opened on the front surface of the flow path switching frame 43. is there.

Inside the flow path switching frame 43, the special discharge port 5 is provided.
3 and the general discharge port 54 are provided side by side. Then, on the rear surface of the mounting substrate 42, a ball lead-out frame 55 that communicates with the flow path switching frame 43 is provided in a protruding manner. On the bottom surface of 55, a partition wall 57 is provided upright in series with the partition member 56, and a special discharge passage 58 communicating with the special discharge port 53 and a general discharge passage 59 communicating with the general discharge port 54 are formed side by side to form a special discharge passage. The special prize detector 60 faces the discharge passage 58 as special game state detecting means. Further, a solenoid storage frame 61 is attached behind the ball lead-out frame 55.

The switching member 45 has a rotary shaft insertion port 4
8 is attached to the rotary shaft 62 provided in the ball lead-out frame 55 so as to be rotatable in the horizontal direction, and is also connected to the plunger 65 of the solenoid 64, which is a driving member, through the incorrect rotation preventing member 63. is doing. Hereinafter, when viewed from the front of the pachinko machine, the illegal rotation prevention member on the right side is referred to as the first illegal rotation prevention member 63a, and the illegal rotation prevention member on the left side is referred to as the second illegal rotation prevention member 63b. The right solenoid is the first solenoid 64a, and the left solenoid is the second solenoid 64b.

The illicit rotation preventing member 63 is a plate member having a substantially L-shaped cross section and has a slide portion 66 at one end and an illicit rotation preventing hole 67 at the other end.
The plunger 65 of the solenoid 64 is connected to one side. The above-mentioned slide portion 66 is the solenoid storage frame 61.
Slides in slide grooves 68 provided on both side surfaces of the.

The improper rotation preventing hole 67 is for inserting the action projection 50 of the switching member 45 to prevent improper rotation due to an operation from the outside, and for rotating the switching member 45 by driving the solenoid 64. The solenoid 64 side serves as the rotation restricting portion 69, and the switching member 45 side serves as the rotating portion 70. After the outer side 71 of the turning portion 70 extends from the outer side 71 of the turning restricting portion 69 as it is, the inner side 72 extends obliquely inward from the inner side 72 of the turning restricting portion 69. , And is parallel to the outer side 71. Therefore, the horizontal width of the rotating portion 70 is wider than the horizontal width of the rotation restricting portion 69.

In the normal state, the action protrusion 5
The switching member 45 is attached so that 0 is located at the rotation restricting portion 69, and the inner side of the rotation restricting portion 69 functions as the rotation restricting surface 73 (solid line in FIG. 12). That is, if the switching member 45 is rotated clockwise from the outside, the second
The action protrusion 50b on the rotation restricting portion 69 of the unauthorized rotation preventing member 63b contacts the rotation restricting surface 73 to restrict the rotation of the switching member 45 (FIG. 10). Similarly, from the outside, the switching member 4
When 5 is rotated counterclockwise, the action protrusion 50a on the rotation restricting portion 69 of the first unauthorized rotation preventing member 63a contacts the rotation restricting surface 73, and restricts the rotation of the switching member 45.
At this time, since the space between the first ball passage port 46 and the second ball passage port 47 of the switching member 45 is located under the special winning opening 44, the balls winning the special winning opening 44 are on the switching member 45. As shown in Fig. 13, the flow down is regulated (Fig. 13).

On the other hand, when the first solenoid 64a is excited and the plunger 65a is attracted, the first illegal rotation prevention member 6
The action projection 50a on the rotation restricting portion 69 of 3a moves into the rotating portion 70 (dotted line in FIG. 12), and while contacting the tip side 74 without being restricted by the rotation restricting surface 73. It rotates counterclockwise about the rotation shaft 62 which is a rotation fulcrum (FIGS. 11 and 14). Therefore, the switching member 45 also rotates counterclockwise around the rotation shaft 62, which is a rotation fulcrum, and the second ball passage opening 47 is located below the special winning opening 44. At this time, “Atari” is displayed on the display window 52, and when a ball wins the special winning opening 44, the ball is held in the second ball passing opening 47 (FIG. 14). Then, when the first solenoid 64a is demagnetized, the plunger 35b is projected by the urging force of the return spring 74, the switching member 45 is rotated back clockwise, and the ball held in the second ball passage opening 47 is specially ejected. It passes through the outlet 53, is guided to the special discharge passage 58, and is detected by the special prize detector 60 (FIG. 15).

Similarly, when the second solenoid 64b is excited and the plunger 65b is attracted, the action projection 50b on the rotation restricting portion 69 of the second illicit rotation preventing member 63b moves into the rotating portion 70. Then, while the movement is not restricted by the rotation restricting surface 73, it rotates clockwise around the rotation shaft 62, which is a rotation fulcrum, while being in contact with the front end side 74. Therefore,
The switching member 45 also rotates clockwise around the rotation shaft 62, which is a rotation fulcrum, and the first ball passage opening 46 is located below the special winning opening 44. At this time, the display window 52 shows “miss”
When a ball is displayed on the special winning opening 44 while being displayed, the ball is held in the first ball passing opening 46. And
When the second solenoid 64b is demagnetized, the plunger projects due to the bias of the return spring 74, the switching member 45 returns counterclockwise and rotates, and the ball held in the first ball passage port 46 passes through the general discharge port 54. Then, it is guided to the general discharge passage 59.

Further, as shown in FIG. 16, the special prize detector 60 is attached to a detector attachment portion 75 provided on the lower outside of the solenoid housing frame 61. This detector mounting part 75
Is a mounting portion 76 on which the base of the special prize detector 60 is mounted.
And a support portion 77 standing upright from the solenoid storage frame 61 on the side of the mounting portion 76. The support portion is provided with a fitting groove 78 into which one side of the special prize detector 60 is fitted. To attach the special prize detector 60 to the solenoid storage frame 61, the special prize detector 6 is mounted on the mounting portion 76 of the detector mounting portion 75.
No. 0 base is placed and the fitting groove 78 of the support 77 is mounted.
One side of the special prize detector 60 is fitted inside. And
The solenoid storage frame 61 may be attached to the ball lead-out frame 55 with a screw or the like so that the other side of the special prize detector 60 is pressed by the rear end surface of the ball lead-out frame 55. Therefore, the special winning award detector 60 can be easily attached without directly using a screw or the like, and the fitting groove 78 makes the positioning easy and accurate.

Next, a game in the pachinko machine having the above structure will be described. When the player operates the firing operation handle to cause the ball to enter the game section 3, the ball hits an obstacle nail and flows down while changing the direction of flow down. When the ball wins the specific winning opening 11, the specific winning detector 10 detects the ball and sends a signal to the electric control device. When the electric control device receives the signal from the specific winning detection device 10, it operates the auxiliary variable display device 6 provided on the front surface of the auxiliary variable winning device 7 to change the number at a speed that the player cannot identify. Display it. Then, when a predetermined time preset in the timer of the electric control device has elapsed, the variable display of the auxiliary variable display device 6 is stopped, and when the stop display forms a preset prize mode, for example, “7 Is displayed, the solenoid 34 of the auxiliary variation winning device 7 is excited for a predetermined time (for example, 6 seconds). Therefore, when the auxiliary variable display device 6 forms the prize mode by the auxiliary variable display device 6, the auxiliary variable winning device 7 opens the opening / closing blades 29, 29 for a predetermined time and converts the opening / closing wings 29, 29 into the second state in which the ball can be easily received. In addition, since the solenoid 34 is demagnetized after a lapse of a predetermined time, the auxiliary variation winning device 7 operates the opening / closing blades 29, 2
It returns to the first state in which 9 is closed.

When the ball that has won the auxiliary variable winning device 7 flows down the storage trough 38 and enters the special winning opening 44 of the flow path switching device 9, this ball passes through the first ball passage opening 4 of the switching member 45.
It stands between 6 and the 2nd ball passage opening 47, and stands by. When the sphere passes through the special winning opening 44, the special area passage detector 8 detects the sphere and sends a signal to the electric control device. Upon receiving this signal, the electric control device operates the three variable displays 14a, 14b, 14c of the variable display device 4 to convert and display the numbers at a speed that the player cannot recognize. Then, when a predetermined time preset in the timer of the electric control device has passed or the player operates a stop switch (not shown), the variable display of the variable display device 4 is stopped, and the three-digit display is performed. The number is stopped and displayed. Then, the electric control device determines whether or not the result mode of the stop display corresponds to a preset prize mode, and when the prize mode is not formed, the electric control device determines the flow path switching device. 9 second solenoid 64b
When the second solenoid 64b is demagnetized after the switching member 45 is rotated clockwise to hold the sphere in the first ball passage opening 46, the sphere held in the first ball passage opening 46 becomes It drops from the general discharge port 54 to the general discharge passage 59 and is processed as a winning ball. If the prize mode is not formed, the game does not change.

On the other hand, when the stop mode of the variable display device 4 forms the prize mode, for example, "7""7""7" or "3".
When "3", "3", etc. are displayed, the electrical control device excites the first solenoid 64a of the flow path switching device 9 to rotate the switching member 45 counterclockwise, and the inside of the second ball passage opening 47 is reached. When the first solenoid 64a is demagnetized after holding the ball, the ball held in the second ball passage port 47 drops from the special discharge port 53 to the special discharge passage 58, and is detected by the special prize detector 60. . When the special winning award detector 60 detects the ball, it sends a signal to the electric control device to the effect that the right to the special game is generated.

When the electric control device receives a signal from the special prize detector 60 that the right to the special game has been generated, the third
The third type starting detector 12 of the seed starting port 13 is enabled. Therefore, after the special game right is generated, the game section 3
When the ball that flows down inside wins the third type starting port 13,
The third type starting detector 12 detects this sphere and sends a signal to the electric control device, and the electric control device sets the solenoid 22 of the variable winning a prize device 5 for a predetermined period, for example, to a timer based on this signal. Excitation is performed only for a period until a predetermined time (10 seconds) elapses, or until a predetermined number (10) of balls are won in the variable winning device 5. Therefore, the variable winning device 5 converts the ball into the second state in which it is easy to accept the ball only during the predetermined period. When a ball wins in the state in which the variable winning device 5 is converted to the second state, the counting detector 26 detects one of the balls and sends a signal to the electric control device, and the electric control device outputs this signal. The number of winning balls is counted based on the above, and when it reaches a predetermined number, the solenoid 22 is demagnetized and the variable winning device 5 is returned to the first state. Even if the number of winning balls does not reach the predetermined number, the electric control device demagnetizes the solenoid 22 and the variable winning device 5 after a predetermined time of 10 seconds elapses.
To the first state. In this way, the variable winning a prize device 5 returns to the first state when either the predetermined time elapses or the number of winning balls reaches the predetermined number, the variable winning device 5 returns to the first state. When the variable display device 4 forms a predetermined prize mode after the above conditions are satisfied as a cycle, the cycle is updated and the special game can be continued a predetermined number of times (for example, the 16th cycle). That is, when the ball wins the third kind starting port 13 after the variable winning device 5 returns to the first state, the third kind starting detector 12 detects the ball and sends a signal to the electric control device.
Based on this signal, the electric control device excites the solenoid 22 of the variable winning a prize device 5, and is updated in the second cycle to continue the special game. In the special game of the second cycle, when the number of winning balls to the variable winning device 5 reaches a predetermined number (10) or a predetermined time (10 seconds) elapses,
The solenoid 22 is demagnetized and the second cycle ends. Then, when the ball wins the third-class start opening 13, it is similarly updated in the third cycle and the special game is continued. In this way, the cycle is updated on condition that the ball enters the third-type starting port 13. However, when the final 16th cycle ends, the special game right disappears, and the cycle is not updated even if the ball wins the third class starting opening 13 thereafter.

As described above, in this embodiment, the ball is the special winning opening 4
The variable display device 4 operates on condition that the variable display device 4 has passed, and when a predetermined prize mode is formed by the variable display device 4, the ball passing through the special winning opening 44 flows down the special discharge passage 58 and receives the special prize. It acts on the detector 60, whereby the right of special game is generated, and the variable winning device 5 is the second for a predetermined period on the condition that the ball wins the third kind starting opening 13 in the state where the right is generated. The game is converted into a state, and after the variable winning device 5 returns to the first state, the cycle is updated and the special game is continued on condition that the ball wins the third type starting opening 13. Then, when a predetermined time elapses in the final cycle or when the number of winning balls reaches a predetermined number, the right of the special game is extinguished at this point and the special game is ended.

When the variable winning device 5 is in the second state, the ball passes through the special winning opening 44 and the variable display device 4 operates, and when the prize mode is formed, the right to the special game disappears. The special game is a so-called puncture that ends at that point. Therefore, when the special game is started, it is desirable to shoot a hit ball aiming at the right side as much as possible so that the ball does not enter the special winning opening 44.

Next, the electric control device will be described.
First, the configuration for controlling the variable display device 4, the auxiliary variable display device 6, and the switching member 45 of the flow path switching device 9 as described above will be described based on the block diagram of FIG. For convenience of explanation, signals are represented by H level “H” and L level “L”.

As shown in FIG. 17, when the special area passage detector 8 of the flow path switching device 9 detects a sphere, "H" is sent to the special symbol operation control means 101, so from the special symbol operation control means 101. Special random number extraction means 1 based on the signal of
02 extracts a random number from the first random number table 103 or the second random number table 104, and sends the extracted random number to the special symbol selection means 105. Also, the special symbol operation control means 10
1 receives the signal from the special area passage detector 8,
Since "H" is sent to the AND gate 106, the first AND gate 106 is opened in synchronization with the pulse from the display update pulse generation means 107, and a signal is sent to the special symbol display control means 108 to control the special symbol display. The means 108 operates the variable display device 4 to display the three-digit number at high speed conversion display at such a speed that the player cannot visually recognize it. Then, when a predetermined time set in advance in the timer 109 of the special symbol operation control means 101 has passed, an "H" signal is sent from the special symbol operation control means 101 to the special symbol comparison means 110, whereby the special symbol comparison means 110 is , The special symbol selecting means 105 is started to compare the stop symbol sent from the special symbol display control means 108 with the symbol of the variable display device 4, and if both symbols match, the special symbol operation control means 101 is displayed. Send a signal. When the special symbol operation control means 101 receives this signal, it converts "H" to the first AND gate 106 into "L", so that the first AND gate 106 is closed, so that the variable display of the variable display device 4 is performed. It is stopped and the three-digit number selected by the special symbol selection means 105 is stopped and displayed. In addition, the special symbol operation control means 101 sends a determination signal to the special symbol stop determination means 111 at the same time as converting the signal to the first AND gate 106 to "L", so the special symbol stop determination means 111 outputs this signal. Upon receipt, it is determined whether or not the symbols (three-digit numbers) stopped and displayed based on the signal sent from the special symbol display control means 108 form the prize mode.

Special symbol stop determination means 111 is "miss"
If it is determined that the "miss" effect is transmitted to the switching drive control means 112, a signal indicating "miss" is sent to the switching drive control means 112, and a signal indicating "miss" is sent to the sound effect generating means 113 described later. Generate a sound. The switching drive control means 112 receiving the "miss" signal selects the solenoid 64 driven by the drive member selection means 114 based on this signal, and sends the signal to the second drive control means 115. In response to this, the second drive control means 115 causes the second solenoid 6
4b is operated for a certain period of time to rotate the switching member 45 clockwise so as to hold the ball in the first ball passage port 46 of the switching member 45, and then drop it into the general discharge passage 59 through the general discharge port 54 and discharge it. To do.

On the other hand, when the special symbol stop determination means 111 determines "Atari", it sends a signal indicating "Atari" to the switching drive control means 112 and also to the sound effect generation means 113 described later. A signal indicating "Atari" is sent to generate the "Atari" sound effect. Upon receiving the "Atari" signal, the switching drive control means 112 causes the drive member selection means 114 to drive the solenoid 64 based on this signal.
Is selected to send a signal to the first drive control means 116. Therefore, the first drive control means 116 operates the first solenoid 64a for a certain period of time to rotate the switching member 45 counterclockwise to hold the ball in the second ball passage 47 of the switching member 45, and then It is dropped into the special discharge passage 58 through the discharge port 53 and discharged. When the ball falls into the special discharge passage 58, the special prize detector 60 detects the ball and sends an "H" signal.

Further, the specific winning detector 1 of the specific winning opening 11
When 0 detects a sphere, “H” is designated as the specific winning control means 117.
Based on the signal from the specific winning control means 117, the normal random number extraction means 118 causes the first random number table 1 to be transmitted.
19 or a random number is extracted from the second random number table 120, and the extracted random number is sent to the normal symbol selecting means 121. Further, when the specific winning control means 117 receives a signal from the specific winning detector 10, it sends “H” to the second AND gate 122, so that the second AND gate 122 outputs a pulse from the display update pulse generating means 123. It opens in synchronization and sends a signal to the normal symbol display control means 124, and the normal symbol display control means 124 operates the auxiliary variable display device 6 to convert a one-digit number at a high speed at a speed that cannot be visually recognized by the player. While displaying, the normal symbol display control means 124 also sends a signal to the effect sound generation means 113 to the effect that the auxiliary variable display device 6 is in the process of display conversion to generate sound effects. Then, when a predetermined time set in advance in the timer 125 of the specific winning control means 117 has passed, an "H" signal is sent from the specific winning control means 117 to the normal symbol comparing means 126, whereby the normal symbol comparing means 126 is normal. The comparison of the stop symbol sent from the symbol selection means 121 and the symbol of the auxiliary variable display device 6 sent from the normal symbol display control means 124 is started, and when both symbols match, a signal is sent to the specific winning control means 117. send. Upon receipt of this signal, the specific winning control means 117 converts "H" to the second AND gate 122 into "L", so that the second AND gate 122 is closed, whereby the variable display of the auxiliary variable display device 6 is performed. It is stopped and the one-digit number selected by the normal symbol selecting means 121 is stopped and displayed. Further, the specific winning control means 117 converts the signal to the second AND gate 122 into “L” and at the same time sends the determination signal to the normal symbol stop determination means 127,
When the normal symbol stop determination means 127 receives this signal, it determines whether or not the symbols (one digit number) stopped and displayed based on the signal sent from the specific winning control means 117 form the prize mode. To do.

Normal symbol stop determination means 127 is "miss"
If it is determined that the “miss” is transmitted to the third drive control means 128, a signal indicating “miss” is also sent to the sound effect generating means 113 described later. Generate a sound effect. In the case of this “miss”, no operation is performed.

On the other hand, when the normal symbol stop determination means 127 determines "Atari", it sends a signal indicating "Atari" to the third drive control means 128 and also to the sound effect generation means 113 described later. A signal indicating "Atari" is sent to generate the "Atari" sound effect. The third drive control means 128, which has received the "Atari" signal, sends a drive signal to the solenoid of the auxiliary variation winning apparatus 7 based on this signal, and also sends the solenoid of the auxiliary variation winning apparatus 7 to the sound effect generating means 113 described later. Is transmitted to generate a sound effect indicating that the auxiliary variation winning device 7 is being driven. Therefore, the auxiliary variation winning device 7 converts the first state, which is disadvantageous to the player, into the second state, which is advantageous to the player, for a certain period of time determined by the timer 129 of the third drive control means 128.

Further, the specific winning control means 117, when receiving the signal from the specific winning detector 10, sends an "H" signal to the first display control means 130, and receives the "H" signal to perform the first display. The control means 130 causes the memory display 131 to store and display the number of winnings in the specific winning opening 11. The memory display on the memory display 131 is specific winning control means 11
In "7", "1" is added each time "H" is sent, and "1" is subtracted each time "L" is sent.
In the present embodiment, the upper limit of storage is "4", but this number is not limited to "4" and can be changed as appropriate.

Switching control of each random number table for extracting random numbers by the special random number extracting means 102 and the ordinary random number extracting means 118 is performed by the random number selecting function means 132. The random number selected for displaying the special symbol on the variable display device 4 is the random number selection function means 132.
It is performed by the first effective use random number display unit 134 via the second display control unit 133 based on the signal from. In this display, when the random number in the first random number table 103 is selected, the lamp is turned off, and when the random number in the second random number table 104 is selected, the lamp is turned on. Also,
The random number selected for normal symbol display on the auxiliary variable display device 6 is performed by the second effective use random number display 136 via the third display control means 135 based on the signal from the random number selection function means 132. In this display, when the random number in the first random number table 119 is selected, the lamp is turned off, and when the random number in the second random number table 120 is selected, the lamp is turned on. The player can know whether the currently selected random number is advantageous or unfavorable to the player by displaying the effective use random number indicators 134 and 136.

As shown in FIG. 18, the random number selection function means 132 selects the first flip-flop 137 for selecting a special symbol to be displayed on the variable display device 4, and the ordinary symbol to be displayed on the auxiliary variable display device 6. The second flip-flop 138 for doing so is the main constituent element. A signal related to the random number change is input from the random number change state detection unit 139 to the random number selection function unit 132.

To the reset input of the first flip-flop 137 of the random number selection function means 132, a reset signal is input via the first OR gate 140 when the electric control unit is powered on or when the reset switch is turned on. It
On the other hand, to the reset input of the second flip-flop 138, the above-mentioned reset signal and the special device operation control means 1
The right generation signal from 41 (FIG. 21) is input through the second OR gate 142.

The clock inputs of both flip-flops 137 and 138 are connected to the third-type starting prize counting means 143 (see FIG. 2).
Special game end signal from 1) (16 count signal)
And the right generation signal from the special device operation control means 141, which is transmitted when the special game becomes a so-called puncture state,
It is input after being delayed by the delay circuit 144. Also,
The first input is applied to the D inputs of both flip-flops 137 and 138.
The inverted Q output of the flip-flop 137 is input. Then, the random number selection function means 132 is the special random number extraction means 1
02 and the ordinary random number extraction means 118, and after resetting the electrical control device, the random numbers of the respective first random number tables 103 and 119 are extracted.
The random numbers in this random number table are compared with the first random number tables 103 and 119, respectively, and the second random number tables 104 and 1
Random numbers are stored so that 20 is advantageous to the player.

Therefore, as shown in the time chart of FIG. 19, the Q output of the first flip-flop 137 after reset is “L”, the output of the inverted Q is “H”, and the first random number table 103 is referred to. ing. Then, the rise of the special game end signal transmitted when the special game ends in a predetermined cycle, or the fall of the right generation signal from the special device operation control means 141 transmitted when the special game enters a so-called puncture state. When the clock is input, the D input at this time is "H" equivalent to the inverted Q output.
Therefore, the Q output is inverted to “H” and the inverted Q output is inverted to “L”, and the second random number table 104 is referred to. Then, the rise of the special game end signal transmitted when the special game ends again in a predetermined cycle, or the rise of the right generation signal from the special device operation control means 141 transmitted when the special game enters a so-called puncture state. When the falling clock is input, the D input at this time is "L" which is equivalent to the inverted Q output, so the Q output is "L".
Then, the inverted Q output is inverted to “H”, and the first random number table 1
03 will be referred. In this way, the random numbers for extracting the special symbols are alternately exchanged with the random number table to be extracted each time the special game is completed.

On the other hand, the Q output of the second flip-flop 138 after reset is “L” and the output of the inverted Q is “H”, and the first random number table 119 is referred to. Then, the rise of the special game end signal transmitted when the special game ends in a predetermined cycle, or the fall of the right generation signal from the special device operation control means 141 transmitted when the special game becomes a so-called puncture state. When the clock signal is input, the D input at this time is "H" equivalent to the inverted Q output of the first flip-flop, so the Q output is inverted to "H" and the inverted Q output is inverted to "L". , The second random number table 120 is referred to. Then, when the right generation signal from the special device operation control means 141 is input, the second flip-flop 138 is reset by the rising of the right generation signal, the Q output becomes "L", and the inverted Q output becomes "H". Then, the first random number table 119 is referred to. Then, the rise of the special game end signal transmitted when the special game ends again in a predetermined cycle, or the rise of the right generation signal from the special device operation control means 141 transmitted when the special game enters a so-called puncture state. When the falling clock is input, the D input at this time is the inverted Q of the first flip-flop 137.
Since it is "L" equivalent to the output, the Q output remains "L" and the inverted Q output also remains "H". Therefore, the first random number table 119 is continuously referred to. Then, again, the rise of the special game end signal transmitted when the special game ends in a predetermined cycle, or the right generation signal from the special device operation control means 141 transmitted when the special game becomes a so-called puncture state. When the falling clock is input, the D input at this time is the first
Since it is "H" equivalent to the inverted Q output of the flip-flop 137, the Q output is inverted to "H", the inverted Q output is inverted to "L", and the second random number table 120 is referred to. In this way, the random number for extracting the normal symbol is referred to the second random number table 120, which is more advantageous to the player when the first special game is finished after resetting, and when the right to the special game is generated, to the player. The first disadvantage
Returning to the random number table 119, the second random number table 120, which is more advantageous for the player, is referred to again by the end of the second special game from that time.

In the above embodiment, the signal input to the clock input of the second flip-flop 138 is a special game end signal transmitted when the special game ends for a predetermined cycle, or a special game is a so-called puncture. Although it is the right generation signal from the special device operation control means 141 that is transmitted when the state becomes the state, the clock input signal is not limited to these, and for example, a signal when a hit ball is won in the special prize detector 60 or , A signal when the launch ball detector that detects the launch ball detects a fixed number of launch balls, or a signal when the specific prize detector 10 detects a fixed number of prize balls, that is, the auxiliary variable winning device 7 is fixed. A signal based on the number of times of operation, a signal when a collected ball detector that detects collected balls detects a fixed number of collected balls, and a difference number that is the difference between the collected balls and the number of prize balls discharged is a fixed number. It is the signal or if the signal or when the special region transmission detector 8 detects a predetermined number of winning ball may be a signal or the like when the variable display device 4 becomes the particular stop mode.

In the above embodiment, the random number tables referred to by the random number extracting means 102, 118 are the first random number tables 103, 119 and the second random number tables 104, 1.
However, the random number table to be referred to is not limited to one set, and a plurality of random number tables may be prepared as shown in FIG.

Five sets of random numbers A to D are provided for determining the special symbols to be displayed on the variable display device 4. The probability of "Atari" generated by the random number table of each set is "1/50" and "1/50" in the A set, "1/50" and "1/25" in the B set,
"1/50" and "1/10" for group C, "1/50" for group D
50 ”and“ 1/5 ”. On the other hand, the random number table for determining the normal symbol to be displayed on the auxiliary variable display device 6 is prepared in five sets A to D. The probability of "Atari" generated by the random number table of each set is "1/10" and "1/1" in the A set, "1/10" and "1/2" in the B set, and "1" in the C set. “1/10” and “1/5”, and D group has “1/10” and “1/10”.

In order to select the random number table to be referred to, first, a set of random number tables to be referred to in the variable display device 4 is determined by an external operation switch installed in the management device or the pachinko machine. The setting by the external operation switch is transmitted to the special random number extracting means 102 via the random number change state detecting means 139 and the random number selecting function means 132, and the special random number extracting means 102 selects a corresponding set of random number tables.
Further, when a set of random number tables referred to by the variable display device 4 is set, the automatic random number selection means 145 causes the variable display device 4 to operate.

The game contents that are advantageous to the player are not limited to those described above, and for example, the opening angle of the ball receiving member 236 is made larger than usual, or the time for the ball receiving member 236 to convert to the second state is extended more than usual. Alternatively, it may be configured such that more hit balls are won in the variable winning device 235.

An outline of an electric control device for controlling the variable winning device 235 and the like in the second type of pachinko machine will be described with reference to FIG. The random number selection function means 253 receives the random number selection signal from the random number change state detection means 254,
The random number extraction signal is transmitted to the special symbol random number extraction means 255. In response to this, in the special symbol random number extraction means 255,
A random number table for extracting a random number is specified, a random number is extracted from the first random number table 256 or the second random number table 257, and a special symbol selection signal is transmitted to the special symbol selection means 258. In response to this, the special symbol selection means 258 transmits the aspect of the special symbol based on the random number of the selected random number table to the variable display control means 259.

The variable display control means 259 has a special prize detector 248 (which also serves as a continuation switch in this embodiment).
From the signal from the special symbol selection means 258,
The signal from the count switch 244 is input.
Then, when the signal from the count switch 244 is received, the display conversion of the variable display device 245 is started by the special symbol selected by the special symbol selection means 258, and the special winning detector 2
When the signal from 48 is received, the display conversion in the variable display device 245 is stopped.

Further, the special symbol determination means 260 determines whether or not the stop display mode of the variable display device 245 described above forms the prize mode. Then, when the prize mode is formed, the signal of "Atari" is output.
This "Atari" signal is input to the variable winning device drive control means 262 via the continuation control means 261. In response to this, the variable winning device drive control means 262 converts the variable winning device 235 from the first state, which is disadvantageous to the player, to the second state, which is advantageous to the player.

The variable winning device drive control means 262 includes continuation control means 261 and start switches 239a, 239.
39b and the special game end control means 263 are connected to each other, and the count switch 244 is connected to the special game end control means 263. Start switches 239a, 2
The operation of the variable winning device 235 when 39b detects a sphere and the continuation of the special game are as described above. Further, if the continuation condition is not satisfied, that is, the special winning opening 247 is won and the special winning detector 248 does not detect a ball within a predetermined time during the special game, or the count switch 244 counts a predetermined number of balls. Or, when the special game ends for a predetermined number of cycles, the special game end control means 263.
Sends a special game end signal to the variable winning device drive control means 262, and the special game ends.

Further, the random number selection function means 253 receives the random number selection signal from the random number change state detection means 254 and transmits the random number extraction signal to the normal symbol random number extraction means 264.
In response to this, the normal symbol random number extraction means 264 specifies a random number table for extracting random numbers, and the first random number table 2
65 or a random number extracted from the second random number table 266,
A normal symbol selection signal is transmitted to the normal symbol selection means 267. In response to this, the normal symbol selection means 267 transmits the mode of the normal symbol based on the random number of the selected random number table to the auxiliary variable display control means 268. To the auxiliary variable display control means 268, the signal from the specific winning award detector 251 and the signal from the normal symbol selecting means 267 are input. Then, when the signal from the specific winning detector 251 is received, the normal symbol selected by the normal symbol selecting means 267 is displayed on the auxiliary variable display device 250.

Further, the normal symbol judging means 269 judges whether or not the normal symbol selected by the above-mentioned normal symbol selecting means 267 forms a prize mode. When the prize mode is formed, the auxiliary variable winning device drive control means 270 drives the auxiliary variable winning device 238,
The first state, which is disadvantageous to the player, is converted into the second state, which is advantageous to the player.

The condition for transmitting the random number selection signal to the random number selection function means 253 by the random number change state detection means 254 is that the special game end signal from the special game end control means 263 is received. That is, every time the special game ends, the random number table for extracting the random numbers is alternately converted. The conditions for the random number change state detection means 214 to transmit the random number selection signal to the random number selection function means 213 are not limited to those described above, and other signals, for example, signals based on the number of shot balls reaching a predetermined number. And so on.

In the above embodiment, the selection switching control of the first random number tables 103 and 119 and the second random number tables 104 and 120 is performed with a certain regularity, but the random number selection method of the random number selection function means 132 is , But is not limited to this.

For example, when the stop symbol of the variable display device 4 corresponds to a predetermined specific mode (for example, the number of the stop symbol is an odd number), the random number selection function means is the first random number means (for example, first, first). Specific random numbers in the second random number tables 103 and 104 (for example, the second random number table 1 advantageous to the player)
The random number extracted from 04) is selected as the random number used for determining the stop symbol of the variable display device 4, and when the above-described specific mode is displayed on the variable display device 4 as the stop symbol, the next variable display The device 4 may be configured to increase the probability that a prize mode is formed. By doing so, an irregular switching element can be mixed in during the regular switching control as in the above-described embodiment, and the switching of the selected random number can be made difficult to predict.

Further, the variable display device 4 is constructed so that the stop symbol of the variable display device 4 can be stored and held, and the stored variable display device 4 is stored.
When the stop symbol and the symbol determined as the latest variable display device 4 stop symbol satisfy a predetermined specific relationship (for example, when both the memory symbol and the determined symbol are odd numbers), , Forcibly changing the stop symbol of the variable display device 4 (for example, changing to an even hit symbol), and making the symbol forcibly changed the stop symbol of the variable display device 4, the symbol forcibly changed (even symbol) ) The random number selection operation of the random number selection function means based on the memory may be made to intervene (the advantageous random number selection based on the storage of the odd symbols is not consecutively performed twice in succession). In this way, the randomness can be further added to the random number selection operation of the random number selection function means having the randomness of the random number selection operation based on the memory of the symbols stopped and displayed on the variable display device 4.

A second embodiment of the electric control device constructed as above will be described below with reference to FIGS. 26 and 27. 26, the same components as those of FIG. 17 are designated by the same reference numerals and the description thereof will be omitted.

Based on the special area passing sphere detector 8 detecting the special area passing sphere, the special symbol operation control means 10
Special random number extraction means 102 that receives a random number extraction command from 1
The random number is extracted from the first random number table 103 or the second random number table 104 according to the selected random number input from the random number selection function means 132 ', and the random number is supplied to the special symbol selection means 105. Then, the variable display device 4 based on the random numbers supplied by the special symbol selection means 105.
The stop symbol is selected and determined, and the selected symbol is supplied to the symbol conversion control means 301.

The symbol conversion control means 301 is a hit that is stored based on a storage signal supplied from a hit symbol classification means 302 (described later in detail) that stores and holds the previous hit stop symbol in the variable display device 4. Stop design (previous Atari mode) is determined, and this stored hit design,
When the selected symbol supplied from the special symbol selection unit 105 satisfies a certain relationship, the mode of the stop symbol is converted into a predetermined symbol mode and is supplied to the special symbol control unit 110, which is stored. When the hit stop symbol and the selected symbol do not satisfy a specific relationship, the selected symbol is directly supplied to the special symbol control means 110.

Thus, the conversion operation of the variable display device 4 based on the control of the special symbol operation control means 101 elapses a predetermined time, based on the symbol comparison start command issued by the special symbol operation control means 101. Symbol comparison means 110
Starts the comparison judgment between the symbol displayed on the variable display device 4 and the symbol supplied from the symbol conversion control means 301. Then, when both symbols match, the special symbol comparison means 110 sends a symbol matching signal to the special symbol operation control means 10
1, the special symbol operation control means 101 stops the conversion display on the variable display device 4 with the input of the coincidence signal (in the present embodiment, the signal to the first AND gate 106 is at a low level). Convert).

As described above, the variable display device 4 displays the symbol selected by the special symbol selection means 105 (or the symbol converted by the symbol change control means 301), and the stopped symbol. The special symbol stop determination means 111 determines whether or not corresponds to the prize mode. If the result of this determination is "miss", the miss signal is supplied to the drive member selection means 114 of the switching drive control means 114, respectively. In this example, the atari signal is
It does not consist only of information that it is Atari,
Mode of the Atari (for example, the display pattern is "7", "7",
It is assumed that "7" or "2", "2", "2", or the like) is output as a signal including information that allows identification.

Special symbol stop determination means 1 as described above
Atari signal output from 11 is a hit symbol classification means 30
It is also assumed that the hit symbol classification means 302 supplies the stored signal of the hit stop symbol to the random number selection function means 132 'and the symbol conversion control means 301 based on the attrition mode in the inputted atari signal. Supply. Thus, the special symbol selection means 1 based on the next random number extraction
When the selected symbol supplied from 05 and the previously stored symbol of Atari mode satisfy a certain relationship,
As described above, the symbol conversion control means 301 forcibly changes the symbol selected by the special symbol selection means 105 and supplies it to the special symbol comparison means 110.

On the other hand, the random number selection function means 132 ′ to which the memory signal is inputted from the hit symbol classification means 302 is a random mode in this memory signal and the random number change state detection means 13.
Input state and past of various signals supplied from 9 (signal input based on power-on or reset, special game end signal from third-class start prize counting means 143, right generation signal from special device operation control means 141, etc.) The random number table selection command to be supplied to the special random number extraction means 102 is appropriately changed based on the memory etc. In this way, by interposing the random numbers extracted from the first random number table 103 or the second random number table 104, which is the first random number means, in the random number table selection for random number extraction, the first random number table 103 and the second random number table 103 The switching operation with the random number table 104 can be made unpredictable.

Therefore, like the random number selection function means 132 in the above-described embodiment (FIG. 17), it is possible to prevent the player from giving up the regularity of changing the random number for random number extraction at a predetermined interval, and the player is concerned. It is possible to further enhance the interest in playing a game on a pachinko machine.

The point that the random number selection function means 132 'integrally selects the first random number means for special symbol selection and the second random number for normal symbol selection is the same as the above-mentioned embodiment. Whether or not the selection random number changing control based on the stored signal from the hit symbol classification means 302 is also applied to the ordinary random number extraction means 118 is not particularly limited. Further, in the above-described embodiment (FIG. 26), only the winning symbol is stored and held by the winning symbol classification means 302. However, for example, the aspect of the lost symbol is stored and retained, and the stored defective display symbol is stored, Special symbol selection means 301
When the stop symbol selected and determined satisfies a specific relationship, the symbol conversion control means 301 is the special symbol comparison means 110.
It is configured to supply a predetermined specific stop symbol to, and based on this specific stop symbol being the stop symbol of the variable display device 4, the random number selection function means 132 'is the special random number extraction means 102. Alternatively, a signal for selecting the second random number table 104 may be output.

Next, the hit symbol classification means 302 is an odd number ("1", "1", "1" stop symbol of the stop symbol) among the hit patterns in the stop symbol of the variable display device 4,
"3", "3", stop design of "3", "5", "5",
"5" stop symbol, "7", "7", "7" stop symbol, "9", "9", "9" stop symbol either) or even ("0", ""0","0" stop design, "2"
"2", "2" stop symbol, "4", "4", "4" stop symbol, "6", "6", "6" stop symbol,
It is assumed that only "8", "8", or "8" stop symbol) is stored and retained, and the symbol conversion control means 301
When the memory of the hit symbol classification means 302 is odd, only when an odd hit symbol is supplied from the special symbol selection means 105, the stop symbol is converted into an even hit symbol and special symbol comparison means. FIG. 27 shows the configuration of the random number selection function means 132 ′ when supplying to the 110.
It will be explained based on.

The random number selection function means 132 'is composed of a first flip-flop 137' and a second flip-flop 138 ', and the special game end signal from the random number change state detection means 139 is passed through the delay circuit 144'. The first flip-flop 137 'and the second flip-flop 13
The reset signal and the right generation signal from the random number change state detecting means 139 are supplied to the clock inputs of 8'and the reset inputs of the first flip-flop 137 'and the second flip-flop 138' via the second OR gate 142 '. To supply to each.

The Q output and the inverted Q output of the first flip-flop 137 'and the second flip-flop 138' are the special random number extracting means 102 and the ordinary random number extracting means 118.
And the first flip-flop 13
The inverted Q output of 7'is D of the second flip-flop 138 '.
It is supplied to one input side of the fourth AND gate 303 having two inputs and two inputs. Further, the other input side of the fourth AND gate 303 is to be inputted with a memory signal from the hit symbol classification means 302, and when the memory of the hit symbol classification means 302 is an odd number, a signal of the memory signal. The level is set to "H", and when the storage is even, the signal level of the storage signal is set to "L", and the output is continued until the storage is changed.

Random number selection function means 1 configured as described above
In 32 ', the Q output of the first flip-flop 137' in the reset state is low level, the inverted Q output is high level, the Q output of the second flip-flop 138 'is low level, and the inverted Q output is high level. The memory signals output from the symbol classification means 302 are set to low levels, respectively. Then, when the display mode of the stop symbol when the right of the special game occurs thereafter is odd, the signal level of the storage signal input to the fourth AND gate 303 from the hit symbol classification means 302 is "H". Then, the fourth AND gate 303 is opened. Thus, when a trigger based on detecting the falling edge of the special game end signal is input, the first flip-flop 137 '
And a high level signal is input to the D input of the second flip-flop 138 ', the Q output of the first flip-flop 137' is high level, the inverted Q output is low level, and the second flip-flop 138 '. Q output is inverted to a high level and the inverted Q output is inverted to a low level. That is, the first flip-flop 137 'and the second flip-flop 137'
Since the Q output of the flip-flop 138 'becomes high level, the second random number table 10 advantageous for the player
4,120 will be used.

As described above, after the second random number tables 104 and 120, which are advantageous to the player, are referred to, the right generation signal based on the right to generate the special game is generated again by the random number selection function means. When input to 132 ', the first flip-flop 137' and the second flip-flop 138 'are reset, the Q output of the first flip-flop 137' is low level, the inverted Q output is high level, The 2 flip-flop 138'Q output is inverted to the low level and the inverted Q output is inverted to the high level, respectively, and the first random number table 103, which is disadvantageous to the player,
119 will be referred to. Since the memory of the winning symbol classification means 302 is an odd number symbol (the signal level is "H"), the odd number symbol is again displayed on the variable display device 4 as the prize mode based on the control of the symbol conversion control means 301 described above. Since it is restricted from being displayed, the winning symbol classification means 3
The memory symbol 02 is inevitably an even symbol (the signal level of the memory signal is “L”), and the fourth AND gate 303 is closed.

Then, the special game end signal based on the end of the special game is the first flip-flop 137 '.
And the clock input of the second flip-flop 138 ', the D input of the first flip-flop 137' is low level, but the second flip-flop 138 'is low.
D input of high level (first flip-flop 137 '
Of the second flip-flop 138 ', only the Q output and the inverted Q output of the second flip-flop 138' are inverted (the Q output is "H" and the inverted Q output is "L"). Therefore, the special random number extraction means 102 continues to use the first random number table 103, which is disadvantageous to the player, while the ordinary random number extraction means 118 uses the second random number table 120, which is advantageous to the player, and the auxiliary variable display device. Only the probability of forming the prize mode for 6 is improved.

As described above, the symbol conversion control means 301 intervenes in the selection change of the stop symbol in the variable display device 4 to prevent the odd number of hit symbols from continuously occurring, thereby giving the player By eliminating the case where the second random number table 104 having an advantageous probability is referred to again, the profits of the player and the game store are balanced. The symbol conversion control by the symbol conversion control means 301 is not limited to the case where the symbol conversion control unit 301 functions to restrict the selection of the second random number table 104.
Prize mode of a specific display symbol (for example, "7", "7",
When “7”) is displayed on the variable display device 4 and the right to the special game is generated, the random number is selected again from the second random number table 104 having the probability of being advantageous to the player.
The special symbol supplied from the special symbol selection means 105 may be configured to be output as an odd symbol again.

Further, the random number table change control based on the stop symbol mode of the variable display device as described above and the stop symbol change control based on the stop symbol memory are the above-mentioned first type pachinko machine and second type pachinko machine. It can also be used in a machine, and the same effects as those exemplified in the above-mentioned third type of pachinko machine can be expected.

First, with reference to FIG. 28, an example of the case where a similar structure is adopted for a first type pachinko machine will be described. Note that, in FIG. 28, those having the same configuration as that of FIG. 23 are denoted by the same reference numerals, and description thereof will be omitted.

On the basis of the start switches 209 and 210 detecting the start winning ball, the variable display control means 219 performs the variable display and stop operation of the variable display device 203 based on the stop symbol received from the symbol conversion control means 311. To control. On the other hand, the special symbol random number extraction means 215, based on the timing of the operation / stop of the variable display 203, the first random number means (first random number) according to the selected random number command input from the random number selection function means 213 '. A random number is extracted from the table 216 or the second random number table 217), and the random number is supplied to the special symbol selecting means 218, and the special symbol selecting means 218 supplies the variable display 20 based on the supplied random number.
The stop symbol of 3 is selected and determined, and the selected symbol is supplied to the symbol conversion control means 311.

The symbol conversion control means 311 is based on the storage signal supplied from the hit symbol classification means 312 which stores and holds the previous hit stop symbol in the variable display 203, and the hit stop symbol stored (previous time). Atari mode)
If the stored hit symbol and the selected symbol supplied from the special symbol selection means 218 satisfy a certain relationship, the mode of the stopped symbol is converted into a predetermined symbol mode. And then supplied to the variable display control means 219, and if the stored hit stop symbol and the selected symbol do not satisfy a specific relationship, the selected symbol is directly supplied to the variable display control means 219. Is configured.

Thus, when the conversion operation of the variable display device 203 based on the control of the variable display control means 219 ends and the symbol supplied from the symbol conversion control means 311 is stopped, the stop symbol corresponds to the prize mode. The special symbol determination means 221 determines whether or not. When the determination result is "Atari", the special symbol determination unit 221 sends a command signal to the variable winning device drive control unit 222, and supplies the Atari signal to the hit symbol classification unit 312. In the present embodiment as well, similar to the third type embodiment, the Atari signal does not consist only of information indicating that Atari is present, but the mode of the Atari (for example, the display symbol is "7",
(7), "7", or "2", "2", "2" (pattern aspect such as "2") is output as a signal including information that can be identified.

As described above, the special symbol judging means 22
Based on the Atari mode supplied from 1, the memory signal of the hit stop symbol is supplied to the random number selection function means 213 'and the symbol conversion control means 311. Thus, when the selected symbol supplied from the special symbol selection means 218 based on the next random number extraction and the stored symbol of the previous Atari mode satisfy a certain relationship, as described above, The conversion control means 311 forcibly changes the symbol selected by the special symbol selection means 218 and supplies it to the special symbol comparison means 110.

On the other hand, the random number selection function means 213 'to which the memory signal is inputted from the hit symbol classification means 312 is the random mode in this memory signal and the random number change state detection means 21.
Based on the input state of the signal supplied from 4 (for example, the signal based on the start / end of the special game input from the special game end control means 224) and the past memory, the special symbol random number extraction means 215 is supplied. That is, the random number table selection command to be changed is appropriately changed.

As described above, by interposing the irregular random number extracted from the first random number table 216 or the second random number table 217 as the first random number means in the selection of the random number table for random number extraction, the first random number table The switching operation between 216 and the second random number table 217 can be made unpredictable. Further, based on the stored signal from the hit symbol classification means 312, the symbol conversion control means 311 forcibly changes the stop symbol supplied from the special symbol selection means 218, thereby hitting the changed stop symbol. By storing in the classification means 312, it is possible to intervene in the change control of the random number selection command to the special symbol random number extraction means 215 performed by the random number selection function means 213 '.

Next, with reference to FIG. 29, an example in which a similar structure is adopted for a second type of pachinko machine will be described. In FIG. 29, the same components as those of FIG. 25 are designated by the same reference numerals and the description thereof will be omitted.

On the basis of the special prize detector 248 detecting the special winning ball, the variable display control means 259 performs the variable display and stop operation of the variable display device 245 based on the stop symbol received from the symbol conversion control means 321. To control. On the other hand, the special symbol random number extraction means 255, based on the timing of the operation / stop of the variable display 245, the first random number means (first random number) according to the selected random number command input from the random number selection function means 253 '. A random number is extracted from the table 256 or the second random number table 257), the random number is supplied to the special symbol selection means 258, and this special symbol selection means 2
58 selects and determines the stop symbol of the variable display 245 based on the supplied random number, and supplies the selected symbol to the symbol conversion control means 321.

The symbol conversion control means 321 is based on the memory signal supplied from the hit symbol classification means 322 which stores and holds the previous hit stop symbol in the variable display 245, and the hit stop symbol stored (previous time). Atari mode)
If the stored hit symbol and the selected symbol supplied from the special symbol selection means 258 satisfy a certain relationship, the stop symbol mode is converted into a predetermined symbol mode. Then, the selected symbol is supplied to the variable display control means 259 as it is when the hit stop symbol and the selected symbol stored in the variable display control means 259 do not satisfy a specific relationship. Is configured.

Thus, when the conversion operation of the variable display 245 based on the control of the variable display control means 259 is completed and the symbols supplied from the symbol conversion control means 321 are stopped, the stop symbol corresponds to the prize mode. The special symbol determination means 260 determines whether or not. This special symbol determination means 260, if the determination result is "Atari", the continuation control means 2
While sending the command signal to 61, the hit signal is supplied to the symbol classification means 322. In the present embodiment as well, similar to the third and second embodiments, the Atari signal does not only consist of information indicating that Atari is present, but the mode of the Atari (for example, the display symbol is " 7 ”,
(7), "7", or "2", "2", "2" (pattern aspect such as "2") is output as a signal including information that can be identified.

As described above, the special symbol judging means 26
Based on the Atari mode supplied from 0, the memory signal of the hit stop symbol is supplied to the random number selection function means 253 'and the symbol conversion control means 321. Thus, when the selected symbol supplied from the special symbol selection means 258 based on the next random number extraction and the stored symbol of the previous Atari mode satisfy a certain relationship, as described above, The conversion control means 321 forcibly changes the symbol selected by the special symbol selection means 258 and supplies it to the special symbol comparison means 110.

On the other hand, the random number selection function means 253 'to which the memory signal is input from the hit symbol classification means 322 is the random mode in this memory signal and the random number change state detection means 21.
Based on the input state of the signal supplied from 4 (for example, the signal based on the start / end of the special game input from the special game end control means 224) and the past memory, the special symbol random number extraction means 255 is supplied. That is, the random number table selection command to be changed is appropriately changed.

As described above, by interposing the irregular random number extracted from the first random number table 256 or the second random number table 257 as the first random number means in the selection of the random number table for random number extraction, the first random number table The switching operation between 256 and the second random number table 257 can be made unpredictable. Further, based on the stored signal from the hit symbol classification means 322, the symbol conversion control means 321 forcibly changes the stop symbol supplied from the special symbol selection means 258, thereby hitting the changed stop symbol. By storing in the classification means 322, it is possible to intervene in the change control of the random number selection command to the special symbol random number extraction means 255 performed by the random number selection function means 253 '.

Although the other embodiments of the selection control of the first random numbers in the first and second types of pachinko machines have been described above, the switching control of the selection of these random numbers is also an accidental operation based on the selected random numbers. Whether or not the second random number selection is switched in conjunction with the switching of the first random number selection is not particularly limited. Further, in the above-described embodiment, the "specific mode" used for the switching control of the random number selection is the "odd hit pattern", but the specific mode is not limited to this and various types other than numbers are used. In a pachinko machine equipped with a variable display device that converts figures and symbols,
When a specific symbol or symbol is displayed, a winning symbol is set as a specific mode, or when a predetermined specific symbol or symbol is displayed at a specific position, a deviation symbol is set as a specific mode. You may.

[0114]

As described above, according to the present invention,
A plurality of random numbers that determine the stop symbol of the variable display device are set, and since the random numbers have a probability of being advantageous to the player and a probability of being disadvantageous to the player, the player has the probability of being advantageous. When the game progresses so that the game is performed and the probability is changed to an advantage, it is possible to obtain a chance to obtain a great profit. Therefore, in the special game, the probability that the prize mode is formed in the variable display device is different because the setting probability of the variable display device is different, and thus the degree of conversion of the variable winning device into the second state, that is, the special game. Since the probability of occurrence will also differ,
It is possible to enhance the interest of pachinko games while giving a moderate amount of fire. In addition, a plurality of random numbers that determine the stop symbol of the auxiliary variable winning device are set, and since this probability is a probability that is advantageous to the player and a probability that is disadvantageous to the player, the probability that the player is advantageous If the game progresses so as to be played under the condition, and if the probability is changed to an advantage, it is possible to obtain a chance to obtain a larger profit.

In addition, since the setting probability of the auxiliary variable display device is different during the normal game, there is a different probability that a prize mode is formed on the auxiliary variable display device, whereby the auxiliary variable winning device is converted into the second state. Since the degree to which they play is different, unlike a pachinko machine that only has a special game and only has a high level of playability, the player can have a chance to make a profit while enjoying the pachinko game.
Further, by changing the probability of the variable display device and the auxiliary variable display device in conjunction with each other according to a preset condition, the profit is increased to a good probability when the probability is changed to a good probability, and a bad probability is generated. In the case of the transition, the profit of the game store can be increased. That is, since the state with the high probability is set after the state with the low probability, the player does not leave the pachinko machine even if the probability is low, and it is possible to contribute to the improvement in the sales of the game store. In addition, since the state with a good probability is set after the state with a bad probability, if a special game occurs at a bad probability, there is a high possibility that the special game will continue to occur with a good probability. , Players can benefit greatly.

In short, since it is possible to provide a pachinko machine in which the operating profit of the game shop is taken into consideration and the profit earned by the player is also taken into consideration, it is possible to maintain the profit balance between the game shop and the player while maintaining the balance between them. You can secure a profit. In addition, not only is the game highly predictive of whether or not a specific game occurs even during a normal game, but the player can enjoy a healthy game without excessively inspiring the player's emotive heart. The interest in pachinko games can be increased.
