DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is parallel to the horizontal row
The present invention relates to a pachinko machine that sequentially stops variable display of three symbols, and when the symbols at the time of the stop are a combination of the big hit symbols, enters a big hit state and opens and drives the variable winning device in a predetermined manner. .

[0002]

2. Description of the Related Art Conventionally, the variable display of a plurality of (for example, three) symbols is sequentially stopped, and when the symbols at the time of the stop become a combination of a big hit symbol, a big hit state is established and a variable winning device is set to a predetermined value. A large number of pachinko machines that are driven open in this manner have been provided on the market. In such a pachinko machine, the player can visually recognize the state in which the variable display of a plurality of symbols is sequentially stopped.

[0003]

By the way, in this kind of pachinko machine, in order for the player to obtain great profit, a combination of symbols displayed when a plurality of symbols are stopped is determined by a predetermined big hit symbol. Combinations, for example, all have the same design. In this case, it is possible to judge whether there is a possibility of a big hit in a state where the symbols except the last one are stopped, and if there is no possibility of a big hit, a change display of the symbol which stops changing at the end is displayed. Even if it can be visually recognized, the player's interest does not turn to the symbol, and only the player's interest is directed to the variable display of the symbol that stops changing only when there is a possibility of a big hit. The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a pachinko machine capable of directing a player's attention to a change display of a symbol that stops changing at the end. is there.

[0004]

In order to achieve the above-mentioned object, in the present invention, the variable display of three symbols arranged in a row is sequentially stopped, and the symbol at the time of the stop is the big hit symbol. In a pachinko machine that is driven to open in a predetermined manner when the combination is a big hit and the variable winning device is opened in a predetermined manner, the last one of the three symbols that is stopped to fluctuate is hidden so as to be difficult for the player to visually recognize. hiding means consists of the character to be provided, by operating the concealing means
The state where the pattern cannot be visually recognized by the concealing means and the concealing means
It is characterized in that the pattern is changed to a state in which the symbol can be visually recognized without flaws . In addition, the fluctuation display of the symbols other than the symbol that is finally fluctuated is stopped, and when the symbol at the time of the stop is likely to be a combination of the big hit symbols, the concealing means is released and the fluctuation is finally stopped. This feature is characterized in that a variable display of the symbol can be visually recognized by a player.

[0005]

[Action] because they are concealed by the end consisting of the variable display brat catcher La <br/> Kuta symbols stopped variation concealment means, the player against the variable display for symbols other than the hidden symbols As the interest gets better, it is not clear how the hidden symbols are displayed in a fluctuating manner, and it is possible to excite the player's sense of expectation. In particular, when there is a possibility of a big hit, the concealing means composed of the character is visually recognized by the player so that the pattern which has been difficult to be visually recognized until then can be visually recognized.
By changing it so that it does not occur, it is possible to give the player a fresh feeling of expectation.

Also, on each of the left and right sides of the game area 3, big hit lamps 11a and 11b which blink when a big hit state is made and notify the player of the fact are arranged.

[0012] At the bottom of the game area 3, there is also provided an out port 12 for collecting hit balls which do not win the above-mentioned winning ports or the like.

By the way, as shown in FIGS. 1 and 2, a symbol display device 20 provided substantially at the center of the game area 3 has:
It is formed collectively on a mounting board 21 mounted on the surface of the game board 1. That is, on the upper part of the mounting board 21,
The winning opening 22 is formed, and the 10
A winning number display LED 23 for displaying the number of winning balls detected by the count detection switch 14 is provided so as to face the front. Further, below the winning number display LED 23, a start storage display LED 24 for notifying that the number of winning balls that have won the starting winning ports 7a to 7c has been stored is also provided so as to face the front surface of the mounting board 21. This start memory display LE
D24 is stored and held when a hit ball wins the start winning opening 7a to 7c during the fluctuation display or the big hit state of the symbol indicators 25a to 25c, and the start storage display LED 24 lights up by the held number. , Symbol display 25a-25
The light is turned off one by one every time the change of c is started.
However, the maximum number of the stored memos is four, and a winning prize beyond that is invalidated.

Further, the mounting board 21 is provided with three symbol indicators 25a to 25c substantially at the center thereof. Since the symbol displays 25a to 25c in the present embodiment are composed of 7-segment LEDs, there are ten types of symbols displayed by the numbers "1" to "0". Then, the symbol display devices 25a to 25c change and display the above numbers at such a speed that the player cannot identify them based on the fact that the hit ball has won the starting winning prize openings 7a to 7c,
When a predetermined time (for example, 5 seconds) has elapsed, the variable display of the left symbol display 25a is first stopped, and then after a predetermined time has elapsed, the variable display of the right symbol display 25c is stopped.
Further, the central symbol display 25b is controlled to stop after a predetermined time has elapsed. Three symbols display 25a when stopped
When all of the symbols displayed in the numbers ２５ to 25c have the same number, a big hit state is established, and as described above, the variable prize device 4 is drive-controlled to generate a large number of prize balls in a short time.

As shown in FIG. 2, a transparent front cover glass 26 is provided on the front surface of each of the symbol displays 25a to 25c, and a concealing means is provided at a position corresponding to the central symbol display 25b in front thereof. shutter member 27 is submerged exit infested hole 28 is provided as a. Thus, the shutter member 27 is hidden so as to hide the symbol display 25b in a normal state.

That is, when the numbers are the same (hereinafter, referred to as a reach state)
The shutter member 27 is immersed in the central symbol display 25
b can be visually recognized by the player. As a mechanism for driving the shutter member 27, as shown in FIG. 2, an engagement piece 29 protrudes rearward from the lower end of the shutter member 27, and an engagement slot formed in the engagement piece 29. 3
The engagement pin 32 protruding from the tip of the lever 31 is engaged with the lever 31. The rear portion of the lever 31 is rotatably supported by a support shaft 33. The rear end of the lever 31 faces a pressing piece 36 fixed to the tip of the plunger 35 of the shutter solenoid 34. Thus, in a normal state where the shutter solenoid 34 is not excited,
When the plunger 35 is lowered by the urging force of the spring 37 provided around the plunger 35, the pressing piece 36
As a result, the rear end of the lever 31 is pushed downward, so that the front end of the lever 31 is raised to the position where the shutter member 27 is raised. That is, the central symbol display 25b is invisible to the player (solid line in FIG. 2). On the other hand, shutter solenoid 3
When the lever 4 is excited, the plunger 35 is attracted and lifted, so that the pressing force of the pressing piece 36 on the rear end of the lever 31 is removed, so that the leading end of the lever 31 is
7, it will descend by its own weight. Therefore, the player can visually recognize the central symbol display 25b (the dashed line in FIG. 2).

The various configurations provided on the game board 1 of the pachinko machine have been described above. The above-described symbol display device 20, the variable winning device 4, and the like are controlled by the control circuit shown in FIG. The control circuit includes a microcomputer 40 as a control center, and an external ROM 41 and an external RAM 42 are connected to the microcomputer 40. The external ROM 41 stores program data indicating a processing procedure, and the external RAM 42 writes and calls necessary data.

The start winning detection switches 13a to 13
c, the 10 count detection switch 14 and the V winning detection switch 15 are connected to the microcomputer 40 via a waveform shaping circuit 43 composed of a flip-flop for preventing chattering.

The clock generating circuit 45 outputs an external interrupt signal via the frequency dividing circuit 44 to the IN of the microcomputer 40.
Output to T terminal. Then, in synchronization with the external interrupt signal, the microcomputer 40 reads the external ROM 41
Execute the main program stored in.

When power is supplied to the power supply circuit 46, a reset signal is output from the reset signal generation circuit 47 to the microcomputer 40, and the reset signal activates an initial program.

A display drive circuit 48, a display selection circuit 49, and a driver 50 are connected to each output port of the microcomputer 40. The symbol display devices 25a to 25c are connected to the display drive circuit 48 and the display selection circuit 49. The display drive circuit 48 and the display selection circuit 49 include not only the symbol displays 25a to 25c but also a winning number display LED 23 and a start storage display LED 2 (not shown).
4 is also connected. These displays are dynamically driven by outputting selected data and display data from the microcomputer 40 at regular intervals. The driver 50 drives the opening / closing solenoid 6 and the shutter solenoid 34 in response to a signal from the microcomputer 40, and the big hit lamps 11a and 11b, the operation lamp 10
The lighting or blinking operation of is controlled.

Among the operations controlled by the control circuit described above, a variable display subroutine showing the procedure of the variable display of the symbol displays 25a to 25c, and a drive when the reach state is determined by the variable display subroutine. The shutter solenoid driving subroutine showing the processing procedure for driving the shutter solenoid 34 will be described with reference to FIGS.

First, the variable display subroutine is shown in FIG.
In the big hit state, the symbol indicators 25a to 25c are normally kept in a state of displaying the symbol that has become the big hit, so it is determined that the big hit flag is set in step S10. In such a case, the following variable display subroutine processing is not executed.
On the other hand, when it is determined that the big hit flag is not set, the state of the symbol display devices 25a to 25c is determined in steps S20 to S50. Specifically, in step S20, it is determined whether or not all of the symbol displays 25a to 25c are in a changing state (state flag = 1), and only the left symbol display 25a is stopped in step S30. It is determined whether or not the state has been changed (state flag = 2). In step S40, the left and right symbol displays 25a, 25
It is determined whether or not c is in a state in which fluctuation has stopped (state flag = 3).
It is determined whether the combination of the symbols displayed by a and 25c is in the reach state (state flag = 4).

When none of the above-mentioned states is present (when the state is not fluctuating), the state flag is 0. At this time, a start storage counter for storing the winning of the hit ball into the start winning openings 7a to 7c in step S60. It is determined whether or not the value of C is 1 or more. If there is no stored value in the start storage counter C, the process ends without executing the following processing of the variable display subroutine.

When the value of the start storage counter C is 1 or more, the timers t1, t2 and t3 are set in step S70, and all the symbol displays 25a to 25-2 are set in step S80.
The change of 5c is started, and the value of the state flag F is set to “1”. The timers t1, t2, and t3 regulate the fluctuation time of each of the symbol displays 25a to 25c, and have a relationship of t1 <t2 <t3; t2-t1 ≒ t3-t2. Then, it is determined in step S90 that the timer t1 has expired. If the timer has not expired, step S90 → the end of the variable display subroutine... ·repeat.

When it is determined that the timer t1 has expired, the variable display on the left symbol display 25a is stopped in step S100 and the state flag F
Is set to "2". Hereinafter, step S1 is similarly performed.
It is determined whether or not the time of the timer t2 has expired at 10, and if it is determined that the time has expired, the variable display of the right symbol display 25c is stopped at step S120 and the value of the state flag F is changed to ""3" is set. Then, when the variable display of the left and right symbol displays 25a, 25c is stopped, it is determined in step S130 whether the display is a reach display. If not, the timer t3 is timed out in step S140. It is determined whether or not the process has been performed, and step S140 → the end of the variable display subroutine ... the start of the variable display subroutine → step S40 → step S until the timer t3 times out.
.. Are repeated, and when the time is up, the process proceeds to step S180.

On the other hand, if the reach display is determined, it is determined in step S150 whether or not the reach flag has already been set. If not, the reach flag is set in step S160 and the timer t4 is set. Is newly set, and the value of the state flag F is set to “4”. Here, the timer t4 is the central symbol display 25b that finally stops changing when in the reach state.
Is extended, and t4> (t3-t
It is selected as the value that has the relationship of 2). Then, step S
At 170, it is determined whether or not the timer t4 has timed out.
0 → Change display subroutine end ・ ・ ・ Change display subroutine start → Step S50 → Step S170 →
Is repeated, and when the time is up, step S1
Go to 80.

When the timer t3 when the reach display is not performed has timed out, when the timer t4 when the reach display is performed,
When the time is up, the variable display of the central symbol display 25b is stopped in step S180, and thereafter, it is determined in step S190 whether or not a combination of the big hit symbols is determined. To reset the reach flag and the status flag to end the variable display subroutine. On the other hand, if it is determined that the hit is a big hit, step S2
At 10, the reach flag is reset, the status flag is reset, and the big hit flag is set.

When it is determined in step S140 that the timer t3 has timed out, it is not necessary to determine a big hit. Therefore, the variable display on the central symbol display 25b is stopped, only the state flag is reset, and the variable display subroutine ends. You may make it.

Next, a drive subroutine of the shutter solenoid 34 driven when it is determined that the reach display is performed in the above-described variable display subroutine will be described with reference to FIG.

First, it is determined in step S300 whether or not the jackpot flag has been set. If not, it is determined in step S310 whether or not the reach flag has been set. If neither the big hit flag nor the reach flag is set, the shutter solenoid 34 is turned off in step S320. If any of the big hit flag or the reach flag is set, the shutter solenoid 34 is turned on in step S330. Is turned on. That is, in the present embodiment, during the big hit state and the reach state, the shutter solenoid 34 is excited to cause the shutter member 27 to enter through the hole 28 so that the player can visually recognize the central symbol display 25b, In states other than the state and the reach state, the shutter solenoid 34 is de-energized to make the shutter member 27 protrude from the hole 28 so that the central symbol display 25b is not visible to the player. In the above description of the operation, the shutter member 27 is immersed so that the player can visually recognize the central symbol display 25b not only during the reach state but also during the big hit state. The purpose of this is to inform the player which type of the big hit is caused by the big hit, and if this notification is not necessary, the shutter member 2 is set in the big hit state.
7, the central symbol display 25b may be made invisible to the player.

The embodiment has been described above. In the above-described embodiment, the shutter member 27 which is mechanically driven as the concealing means is shown. However, the shutter member 27 is a movable decorative member provided with a character such as a person. It is desirable to operate to open or close anyway. Further, an electric means may be used as the concealing means. For example, a dimming liquid crystal sheet that becomes transparent when a voltage is applied to the front cover glass 26 and becomes opaque when no voltage is applied may be affixed.
The driving display may not be performed until b reaches the reach state, or the driving display may be performed at a low luminance.

In the above embodiment, the central symbol display 25b is not visible to the player at all by the shutter member 27. However, the shutter member 27 is made translucent, or the size of the symbol display 25b is reduced. May also be made smaller so that it is difficult to see.

As the symbol display devices 25a to 25c,
Although a 7-segment LED is shown, other indicators, for example,
LCD, EL, dot matrix display,
It may be a rotating drum or the like. Also, the number of symbol displays is not limited to three, but may be more. In this case, a shutter member is provided for each of the symbol displays that fluctuate and stop after the third, and when there is a possibility of a combination of big hit symbols, the shutter members are sequentially driven to sequentially play the symbol indicators. It may be made visible to a person.
Further, the fluctuation stop signal of the symbol display may not be controlled only by time, but may be generated by a stop switch that can be operated by a player.

[0034]

Effect of the Invention] Thus, as it is apparent from the description, in the present invention, since last being concealed by concealing means comprising a variable display brat Yarakuta variations symbols stopped, except hidden symbols The player's interest in the variable display of the symbol is also improved, and it is not clear how the hidden symbol is displayed in a variable manner, which can excite the player's expectation. In particular, when there is a possibility of a big hit, a concealing means composed of a character is played so that a pattern which has been difficult to recognize until then can be visually recognized.
The player can be given a fresh feeling of expectation by changing it so that it cannot be visually recognized by the player.
