In the symbol display device 36 as described above, when the first symbol indicator 21a at the upper stage is turned on and the second symbol indicator 21b at the lower stage is turned off, the light emitted from the first symbol indicator 21a is emitted from the first half mirror 22a and the first half mirror 22a. Since the light is reflected by the second half mirror 22b and guided to the center display lens 32, the player can visually recognize the display mode of the first symbol display 21a through the display window 28 (FIG. 4). When the second symbol display 21b of the lower story is turned on and the first symbol indicator 21a of the upper row is turned off, the second symbol display of the lower row is turned off.
Since the light emitted from the symbol display 21b passes through the second half mirror 22b and is guided to the center display lens 32, the player can visually recognize the display mode of the lower second symbol display 21b through the display window 28. (FIG. 5). Further, when the upper and lower first symbol display 21a and the second symbol display 21b are simultaneously turned on, the display modes of the two symbol indicators 21a and 21b are combined, and the combined display mode is displayed from the display window 28 by the player. You can see it. Furthermore, when the upper and lower symbol indicators 21a and 21b are turned off and the lamp L2 housed in the first display chamber 35a is turned on, the pattern drawn on the first half mirror 22a can be displayed (FIG. 6). ). The lighting and extinguishing of each symbol display 21 are controlled by display control means (not shown).

According to the symbol display device 36 having the above-described configuration, various display modes can be created, it is possible to correspond to various game modes, and the visual effect is significantly improved. In addition, the first symbol display 21a and the second symbol display 21b
The dynamic change at the time of switching is also a visual stimulus and gives a fresh surprise to the player. Further, in the illustrated embodiment, the lower second symbol display 21b is connected to the upper first symbol display 2b.
Since it is larger than 1a, when switching from the first symbol display 21a to the second symbol display 21b, the symbol to be displayed can be enlarged and a zoom-up effect can be obtained. When the lamps 21a and 21b are turned on at the same time, the display mode of the first symbol display 21a and the display mode of the second symbol display 21b are combined to enable a display full of a three-dimensional effect.

Then, in the central accessory unit 14 of the present embodiment,
The center case 29 is separated by a partition, and the first symbol display 21a
And three symbol display devices 36 each composed of a second symbol display 21b and both half mirrors 22a and 22b are connected in the horizontal direction, and each of the symbol indicators 21 is controlled to be turned on and off by the display control means. . Further, in the illustrated central role unit 14, a windmill 37 is provided in the vicinity of the display window 28 at an obliquely lower position.

A starting port switch 50 is provided in the middle of the guiding gutter 49 while providing the starting port 49. In the illustrated embodiment, a lamp L4 is provided below the starting port 15b, and a tulip-type accessory 51 as the accessory winning tool 19 is provided beside the starting port 15b.

Next, a specific game of the pachinko machine 1 provided with the central accessory unit 14 having the symbol display devices 21 having the above-described configuration will be described with reference to a block circuit diagram, a time chart, and a flowchart.

Reference numeral 52 denotes a central processing unit (hereinafter referred to as a CPU) including a timer, a RAM used for calculating data, and the like; 53, a clock circuit for supplying a predetermined pulse to the CPU; 54, a reset circuit for resetting the CPU; A power reset circuit for initializing a CPU or the like when power is turned on, a frequency divider circuit 56 for supplying a desired pulse to the reset circuit, and a memory 57 storing a program and data for operating the CPU. (Hereinafter referred to as ROM), 58 is an input / output control device, 5

Is a continuous winning switch circuit, 48 is a 10 count switch, 71
Is a 10 count switch circuit.

When the power is turned on, the CPU 52 performs initial settings such as clearing of the RAM and checking of each part, and if there is no abnormality, each symbol display device 36... That is, the left symbol display device 36l and the middle symbol display device 36c are 0 to 9 and 11
, And the letters A, H, and L are sequentially displayed at low luminance as a display mode, and the right symbol display device is displayed.
Numerals 36r indicate 0 to 9 and 11 and alphabetic characters A, H, L, and F are sequentially displayed at low luminance in a cyclic manner. It should be noted that the above numbers 0 to 9, 11 and A, H,
The letter L is hereinafter abbreviated as a symbol. The player visually recognizes, as a display mode, the symbols visually displayed by each of the symbol display devices 36 through the display window 28. In the present invention, the player is energized in this state to actually visually display the symbols. Only the first symbol display 21a in the upper stage, and the second symbol display 21b
Is off. In other words, the player is the first symbol display 21a
Is visually recognized at the position of the second symbol display 21b via the first half mirror 22a and the second half mirror 22b.

Then, the hit ball fired by the player jumps into the starting port 15a provided in the game section 9 or the starting port 15b provided in the variable winning device 16, and when the starting port switch 50 is turned on, a symbol stop process is performed. That is, the first symbol display 21 of each symbol display device 36...
“a” increases the brightness and starts a bright and fluctuating display. Even in this state, the second symbol display 21b is turned off. When 5 seconds elapse after each symbol display device 36 starts to fluctuate brightly, the stop symbol of the left symbol display 21l is determined. This symbol is determined by generating a random number for the left symbol by an interrupt process of the CPU 52 and corresponding to the random number at the time point after the elapse of 5 seconds.

After the left symbol is determined, for example, 0.3 as a fixed time
When the time obtained by adding the determined symbol stop timing adjustment time to the second elapses, the first symbol display 2 in the upper stage of the left symbol display device 36l.
At the same time as 1a is turned off, the lower second symbol display 21b is lit brightly, and the symbol determined as described above is displayed brightly. At this time, in the illustrated embodiment, the second symbol display 21b in the lower stage is larger than the first symbol indicator 21a in the upper stage.
Since the display pattern is suddenly enlarged by switching to 1b, the player feels a fresh surprise with an illusion that the display pattern is zoomed up, and the visual effect is extremely high.

It should be noted that the above-mentioned fixed time is merely provided for providing an interval, and thus may not be particularly provided.In the present embodiment, the left symbol display device 36l, the middle symbol display device 36c, and the right symbol display device are provided.
This is set because 36r may stop at the same time. The symbol determination stop timing adjustment time varies from a minimum of 0 seconds to a maximum time required for the symbols to be sequenced, for example, about 0.2 seconds, and the determined symbols and the symbol indicators 21 are displayed. This is the time required to match the symbol.

When the left symbol display device 36l stops, the middle symbol is determined. In the middle symbol display device 36c, as in the case of the left symbol display device 36l, the first symbol display 21a of the middle symbol display device 36c is turned on when a time obtained by adding the fixed symbol stop timing adjustment time to the fixed time has elapsed. The light is turned off, the second symbol display 21b is turned on, and the determined symbol is visually displayed by the second symbol display 21b. Therefore, the player feels fresh impression again because the middle symbol appears to be enlarged at the same time as the stop.

When the middle symbol stops, the right symbol is determined, and the first symbol indicator 21a of the right symbol display device 36r is turned off after the time obtained by adding the determined symbol stop timing adjustment time to the fixed time similarly to the above, and the second symbol is turned off. The symbol display 21b is turned on to visually display the determined symbol. Also in the right symbol display device 36r, the player suddenly feels a fresh impression because the displayed symbol is suddenly enlarged.

Instead of setting the fixed time, for example, in the middle symbol display device 36c, the determination of the stop symbol is performed when the left symbol is stopped, but the determination timing of the middle symbol is determined after a predetermined time has elapsed after the left symbol is stopped. If it is set so that it is possible to prevent the left symbol display device 36l and the middle symbol display device 36c from stopping at the same time without setting the fixed time, it is possible to obtain the same effect as the setting of the fixed time Can be.

In this embodiment, the time until the symbol is determined is RO
The CPU 52 appropriately determines according to the program stored in the M57. However, a variation time reduction button (not shown) that can be externally operated by the player is provided on the outer frame 2 of the pachinko machine 1, and the variation time reduction button is provided. The change time may be reduced by a user.

Then, after elapse of 0.5 seconds from the stop of the right symbol display device 36r, the CPU 52 determines a combination. As the winning combination, the stopped symbols displayed by the stopped symbol display devices 36... Are used as the identification information, and the case where all the stopped symbols match each other is set as a big hit (big winning).
That is, for example, the case where the left symbol display device 36l visually displays “7”, the middle symbol display device 36c also displays “7”, and the right symbol display device 36r also displays “7” is a big hit. Become. If the winning combination is not established, one second after the determination of the winning position, the second symbol display 21b of each symbol display device 36 ... is turned off while brightly displaying the stop symbol blinking, and the first symbol indicator 21a is lit dark. Then, the variable display of the symbol is restarted at a low luminance.

As a result of the role determination, if the big hit is established, the second state is established in which the game is advantageously developed for the player. That is, each of the symbol display devices 36... Blinks for 4 seconds to display a stopped symbol, and after 4 seconds, the solenoid SOL of the variable winning device 16
And the gate 40 is rotated to open the special winning opening 44. The opening of the special winning opening 44 continues for about 30 seconds or until ten balls enter the special winning opening 44. In addition, grand prize mouth 44
When the continuation switch 45 detects the ball flowing into the
After one second elapses after closing the gate 40, the gate 40 is rotated again to open the special winning opening 44. The winning opening 44 can be opened up to ten times. After the gate 40 is closed, the valid time is limited so that the continuation switch 45 operates effectively only for one second. This is because the longer the effective time of the continuation switch 45 is, the easier the game is to be continued, and there is a risk that the gambling may be unnecessarily incited. Simultaneously with the opening of the special winning opening 44, the left symbol display device 36l displays the number of times the gate 40 has been opened while the second symbol display 21b changes color between green and red. The middle symbol display device 36c is off. Further, the right symbol display device 36r displays the number of winning balls in the large winning opening 44 alternately brightly in green and red. In the illustrated embodiment, when the continuation switch 45 is turned on, the lamp L1 is turned on for one second, and each of the symbol indicators 21.
The display color is switched.

When one second elapses after the last opening of the gate 40 is completed, the second of the left symbol display device 36l, which has been brightly lit up to now, is second.
The symbol display 21b is turned off, the first symbol display 21a is dark, and the fluctuation display is restarted. In the middle symbol display device 36c, the first symbol display 21a changes to a dark and fluctuating display. Right symbol display device 36r
In, the first symbol display 21a is dark and restarts the fluctuating display. Then, the first symbol display 21a of each symbol display device 36 as described above waits for the next ball to enter the starting port 15 in the normal game state in which symbols are darkly displayed.

Further, the gate as described above will be described from the control means side. The CPU 52, the ROM 57, the LED decoder circuit 59 of the input / output control device 58, the LED drive circuit 60, the LED display selection circuit 65, and the LE
The D connection circuit 61 and the like constitute display control means, and control the display mode of each symbol display device 36. Also,
The LED color selection circuit 65, the red LED drive circuit 66, and the green LED drive circuit 67 constitute emission color control means, and switch the color of the symbol display device 36 at the time of a big hit.

The LED decoder circuit 59 receives a bit display signal (a signal instructing which symbol is to be displayed) output every single time from the CPU 52, and outputs this display signal to each decoder signal (each segment) corresponding to each segment. On the other hand, and outputs the signal to the LED drive circuit 60. The LED drive circuit 60 receives the decoder signal, performs current amplification or the like sufficient to light each segment, and supplies the amplified signal to the LED connection circuit 61.
Further, the luminescent color control means receives a luminescent color designation signal output from the CPU 52 at a constant cycle, and causes the red LED and the green LED to emit light alternately. The LED display selection circuit 64 receives a display selection signal output from the CPU 52 at a fixed cycle, and selects a symbol signal to be supplied from the LED drive circuit 60 based on the selection signal from among the symbol displays 21. The LED display duty switching circuit 62, which outputs a signal for selection, receives an output from the LED display light / dark switching circuit 63, and switches the ratio (duty) of the output time of the selection output to each of the symbol displays 21. Is switched. The display signal and the display selection signal are always output from the CPU 52. That is, during the normal operation of the pachinko machine 1, the first symbol display 21a of each symbol display device 36... Illuminates darkly (low brightness mode), and the numerals 0 to 9, 11 and the characters A,
H and L are sequentially displayed in a fluctuating manner. When a hit ball enters the starting port 15 and the starting port switch 50 is turned on, the first symbol display in each symbol display device 36.
The brightness level of 21a is switched to bright lighting (high brightness mode).

When the predetermined time set in the timer elapses after the brightness level switching, the CPU 52 outputs the display signal and the display selection signal,
It has a function to hold the state at that time or at the time when a predetermined time has elapsed, for a certain period of time, whereby the variable display of the symbol display 21 is stopped for a certain period of time. Specifically, when a ball enters the starting port 15, the starting port switch 50 is turned on,
Each symbol display device 36 starts to fluctuate brightly, and after 5 seconds or more have passed since the start port switch 50 was turned on, first the left symbol display device 36l stops bright, and after the left symbol display device 36l stops, a predetermined After the random time elapses, the middle symbol display device 36c stops, and after the middle symbol display device 36c stops, and after the random time elapses, the right symbol display device 36r stops bright. The random time is determined by the CPU 52 generating a random number. Therefore, each symbol appears equally on each symbol display device 36.

The CPU 52 and the ROM 57 also function as determination means, and determine whether or not the symbol displayed when the variable display of the symbol display device 36 has specific identification information has specific identification information. When it is determined that the information is information, a drive signal is output to the solenoid drive circuit 69, and a display signal is output by hitting each symbol display device. For example, in a case where the CPU 52 determines a combination 0.5 seconds after the right symbol stops, and sets a state in which the symbols displayed by the three symbol display devices 36l, 36c, and 36r match as a specific identification state (so-called big hit). For example, if each of the symbol display devices 36l, 36c, 36r is displaying "7", the determining means determines that "big hit", outputs a drive signal to the solenoid drive circuit 69, and displays a predetermined big hit display. Each symbol display device 36 to perform
The display signal is output to. Then, the CPU 52 also activates the electronic sound circuit 72 to generate a jackpot effect sound, and activates the lamp drive circuit 73 to turn on or blink an indicator lamp or the like consisting of the lamp group 74 to visually confirm the achievement of the jackpot. Along with the display, it is also displayed audibly.

Furthermore, in the present embodiment, the symbols displayed by the left symbol display device 36l and the middle symbol display device 36c match, and the right symbol display device 36r
If any of the characters A, H, and L is displayed, the determination means determines that the hit is a small hit, generates a sound effect different from that of the big hit, and causes the solenoid drive circuit 69 to perform a predetermined time, for example, 2 seconds.
Output drive signal for second. And the solenoid drive circuit
When 69 receives a drive signal from the CPU 52, it excites the drive solenoid SOL for 2 seconds, whereby the gate 40 rotates and the variable winning device 16 is converted to a second state advantageous to the player who has opened the large winning opening 4. You. The drive signal is continuously output for a predetermined time according to the combination, and the second state of the variable winning device 16 is continued for the predetermined time.

Each 10-count switch 48 counts the number of balls entered in the variable winning device 16, and the total of the counted values is "1".
When "0" is reached, a drive stop signal is output from the 10 count switch circuit 71, and the CPU 52 stops outputting the drive signal even before the time for which the second state is to be continued, and the gate 4
Close 0.

When a ball wins in the special winning opening 46 provided in the special winning opening 44, the continuation switch 45 is turned on, and the continuous winning switch circuit is turned on.
A continuation signal is output from 70 to the CPU 52. In this case, the second state of the variable winning device 16 is temporarily stopped after 10 counts, and then restarted again.

Furthermore, when a plurality of balls enter the starting port 15, the CPU 52 stores up to four entering balls, and the stored number is visually displayed by a starting storage number indicator light 31 provided in the central role unit 14,
After the determination of the winning combination, one display lamp 31 is turned off after a predetermined time elapses based on the determination result, and the symbol is continuously displayed in a bright and fluctuating manner.

As described above, the present invention has been described with reference to the embodiment in the drawings. However, the present invention is not limited to the above-described embodiment, and can be appropriately implemented as long as the configuration described in the claims is not changed. For example, in the symbol display device in the illustrated embodiment,
Although two symbol displays and two half mirrors are used, the symbol display device may be configured with two symbol indicators and one half mirror. Also, in the illustrated embodiment, the variable winning device is opened by the identification information created by the variable display device and the game is advantageously developed for the player, but the identification information is combined with other information or conditions to play the game. The game can be developed advantageously for the player.

<Effects of the Invention> In short, the present invention switches between the one symbol display that displays the symbols variably and the other symbol indicator that stops and displays the symbols by the display control means, and changes the symbols displayed by each symbol indicator. Since the half mirror is seen through or reflected by the half mirror, the visual stimulus when the display of the symbol is switched from the variable display to the stop display is large, and the player has a fresh It can surprise and impress, and can significantly improve the interest of pachinko games. In addition, compared to the conventional one in which the fluctuation display and the stop display are performed by one symbol display, the actual feeling that the fluctuation of the symbol stops and the visual effect accompanying it increase, and the symbol that has stopped further means Makes pachinko games complicated and profound, including expectations and disappointments.
