Similarly, in a normal game, if the combination of symbols "bell"-"bell"-"red 7" appears, the combination of symbols "bell"-"bell"-"blue 7" or the symbol "bell"-" Bell"-"BAR" combination, also wins small prizes, and then pays ten medals each.

Also, in normal games, if three identical "plum" symbols appear on any active payline, you win a replay and can play another game without having to insert any medals, even if no medals are paid out. In addition, a combination of three "plum" symbols is also a combination that appears in JAC game winning in the JAC game during the RB game. The JAC game refers to a game of trying to get a combination of "plum"-"plum"-"plum" on the central payline L1 in the RB game.

Also, in a normal game, if a symbol "cherry" lands on an activated payline of the first reel 3, a small prize is won and two medals are paid out, which is called "two medal cherries". When betting three medals, if a symbol "Cherry" lands on two activated paylines, four medals are paid out, this is called "Four Medal Cherries".

9 and 10 show the circuit configurations arranged on the main control board 61 and sub-control board 62 for controlling the game processing operation of the slot machine 1 described above.

The main control board 61 shown in FIG. 9 has a control unit and other circuits for sampling random numbers, and the control unit includes a microcomputer 63 as its main part. The microcomputer 63 includes a main CPU (Central Processing Unit) 64 that performs control operations according to preset programs, a program ROM (Read Only Memory) 65 as a program storage device, and a control RAM (Random Access Memory) 66 that can be backed up. The CPU 64 is connected to a clock pulse generator 67 and a frequency divider for generating a reference clock pulse, a random number generator 69 for generating a certain range of random numbers, and a random number sampling circuit 70 for specifying one of the generated random numbers . In addition, the input/output port 71 is also connected to transmit signals with peripheral devices (exciters) described below. The ROM 32 has a separate storage unit for storing the winning probability table, symbol table, winning symbol combination table and sequence program.

The main actuators whose operation is controlled by control signals from the microcomputer 30 include stepping motors 45 for rotationally driving the respective reels 2, 3 and 4, various lamps (game operation indicator lamps 13-15, Start light 17 and winning light 19), various display units (prepaid amount of game medal display unit 16, chance LEDs 9-12, bonus point count display unit 18, payout medal amount display unit 20) and a storage box for accommodating medals 72. These are driven by a motor driving circuit 73, a single lamp driving circuit 74, a single display unit driving circuit 75 and a tank driving circuit 76, respectively. These drive circuits 73 - 76 are connected to the CPU 64 through the input/output port 71 of the microcomputer 63 .

The main input signal generating means for generating the input signal required by the microcomputer 63 so as to generate the control signal includes: an insertion medal sensor 83 for detecting any medal inserted into the medal insertion slot 8; Any operation; prepaid medal insertion switches 25-27 and prepaid medal adjustment switch 29 described above. In addition, there is a reel position detection circuit 77 which detects the rotational position of each reel 2, 3, 4 when receiving an output pulse signal from the photosensitive element 49. A photosensitive element 49 is included in the drive mechanism of each reel 2-4, not shown in this figure.

After the reel 2-4 starts to rotate, the reel position detection circuit 77 counts the number of drive pulses supplied to each stepping motor 45, and writes these counted values into a predetermined area in the RAM 66. Accordingly, RAM 66 stores count values corresponding to the rotational positions of each reel 2-4 within one rotational cycle. On the other hand, the photosensitive element 49 detects the shutter 50 every rotation cycle of the reel 2-4, generating a reset pulse. The reset pulse is supplied to the CPU 63 through the reel position detection circuit 77, and clears the count value of the drive pulses counted in the RAM 66 to "0".

This clearing process eliminates any discrepancies that occur between the motion display of each symbol and each rotation of the stepping motor 45 for one rotation cycle.

The input signal generating device described above also includes: a reel stop signal circuit 78, which generates a signal for stopping the corresponding reel when any of the stop buttons 31, 32, 33 is pressed; a medal detection unit 72s for counting the storage box 72 medal payout quantity; and unrepresented payout composite signal generating circuit. When the count value of actually paid-out medals input from the medal detection unit 72S reaches the payout amount data indicated by the count signal input from the display unit drive circuit 75, the payout composite signal generation circuit generates a signal indicating that the medal payout is complete. Each circuit constituting these input signal generating means is also connected to the CPU 64 through the input-output port 71.

The sub-control unit communication port 79 is connected to the input-output port 71 . The microcomputer 63 transmits signals to the sub-control board 62 through the sub-control unit communication port 79 . The sub-control board 62 shown in FIG. 10 is equipped with a main control unit communication port 80 for receiving this signal. Communication between the sub-control unit communication port 79 and the main control unit communication port 80 is performed only in one direction from the sub-control unit communication port 79 to the main control unit communication port 80 . In this embodiment, the signal transmitted from the sub-control unit communication port 79 to the main control unit communication port 80 is composed of a 7-bit long command type representing its control type and an 8-bit or 24-bit long signal representing the command content. composed of parameters.

The sub-control board 62 has a control unit including a microcomputer 81 as its main components, and another circuit for sampling random numbers. As in the case of the microcomputer 63 in the main control board 61, the microcomputer 81 also includes a sub CPU 82 that performs control operations according to preset programs; a program ROM 83 as a program storage device, and a control RAM 84 that can be backed up. The CPU 81 is also connected to a clock pulse generator 85 for generating reference clock pulses, and a frequency divider 86. In addition, an input and output port 87 is connected for transmitting signals with the main control unit communication port 80 and the exciter described below. The sub-CPU 82 calculates the data required for displaying the game machine data on the liquid crystal panel 39d according to the command sent from the main control board 61 for each game, and updates the data stored in the control RAM 84 to calculate the data for each game.

The exciter whose operation is controlled by the control signal of the microcomputer 81 includes reel backlights 47a, 47b and 47c embedded in the reels 2-4, respectively. The lighting of these reel backlights 47a-47c is controlled by an excitation signal from a lamp driving circuit 89 connected to the input and output port 87. In addition, the input signal generating means for generating input signals necessary for the microcomputer 81 to generate control signals includes the cross key 23, the A key 24 and the B key 25 described above. Furthermore, a game state monitoring timer 97 is connected to the input/output port 87 . This timer 97 is set by the sub CPU 82 when starting a game, and measures the elapsed time from the start of the game.

A picture control 1C (integrated circuit) 90 and a sound source 1C91 are also connected to the input/output 87 . The image control 1C 90 is connected to a character ROM 92 for storing character data and a video RAM 93 as a memory for color display representation. The image control IC 90 displays images on the liquid crystal panel 39d of the reel display window unit 39 under the control of the microcomputer 81. The microcomputer 81 fetches information such as the current game state and the winning token type from the main control board 61 through the main control unit communication port 80, and selects an image effect pattern to be displayed according to the fetched game state and winning token. Then it controls the image control 1C 90 so that the liquid crystal panel 39d displays the selected pattern. The liquid crystal panel 39d can be made to display information desired by the player by operating the cross key 23, the A key 24, and the B key 25.

The sound source 1C 91 is connected to a sound ROM 94 storing sound data. Under the control of the microcomputer 81, the sound source IC 91 makes the speaker 96 emit sound through the power amplifier 95. According to the command input from the main control board 61 through the main control unit communication port 80, the microcomputer 81 controls the sound source 1C 91 and the power amplifier 95, so that the speaker 96 produces the medal insertion sound and the start lever operation sound during the bonus game, The sound effect of the stop button operation sound is the same as the game sound.

In the slot machine 1 according to this embodiment having the structure described above, when the player operates the start lever 30, this operation causes the start switch 303 to be turned on. This ON signal is detected by the main CPU 64 through the input-output port 71. The main CPU 64 then controls the motor drive circuit 73 that drives the stepper motor 45, causing each reel 2-4 to rotate. Simultaneously with this rotation, the main CPU 64 executes probabilistic lottery processing. By referring to the lottery probability table stored in the program ROM 65, the lottery of the winning mode inside is drawn. The type of internal winning mode drawn and the current game state are sent to the sub-control board 62 through the sub-control unit communication port 79 .

As each reel 2-4 is spun, a moving sequence of symbols is variably displayed in each window 5-7. The player tries to adjust the timing of operating each of the stop buttons 31-33 while observing this variable display, and performs the pushing operation of each of the stop buttons 31-33 at an appropriate timing. The operation of each of the stop buttons 31-33 is detected by the main CPU 64 through the reel stop signal circuit 78. At this detection time, the supply of drive pulses to each stepping motor 45 is stopped by the control of the main CPU 64. When the supply of the drive pulse to each stepping motor 45 is stopped, each reel 2-4 stops rotating, and the symbol corresponding to the operation time of each stop button 31-33 stops being displayed on each window 5-7. At this point, if any predetermined combination of symbols represented in the paytable ceases to be displayed in this window 5-7, a win occurs. When winning occurs, the main CPU 64 controls the bin drive circuit 76 that drives the bin 72, and a predetermined number of medals are paid out from the payout opening 35 to the receiving tray 34.

Therefore, there are fewer obstacles interposed between the transparent acrylic plate 39a and the reel 2-4, on which the light is variably displayed, in a manner that prevents the passage of light. Therefore, the visibility of the variable display symbols on reels 2-4 is increased.

In addition, these openings 5b, 6b and 7b are formed corresponding to the rows of variable display of these symbols. Therefore, with the light guide plate 39g also located between the opening 5b and the opening 6b and between the opening 6b and the opening 7b, the light from the cold cathode tube 40a is guided toward the liquid crystal panel 39d. As a result, the visibility of the variably displayed symbols on the reels 2-4 is increased, and with the liquid crystal panel 39d between the respective display windows 5-7, brightness can be obtained.

As described above, according to the present invention, a liquid crystal display panel for variable display patterns placed in front of the variable display device serves as a new machine part for performing game effects. In addition, a base frame and a panel frame are interposed between a transparent flat panel and a liquid crystal display panel on the surface of the machine. Therefore, the display unit of the liquid crystal display panel for displaying game effects is placed in a recessed position from the transparent flat plate. Thus, new game effects can be implemented on the liquid crystal display panel, which helps to maintain the innovativeness of game effects. Also, since the LCD panel is located in a recessed position, its display unit is equipped with a sense of depth. In addition, blind spots for viewing the display unit are eliminated, so that the display unit can be clearly viewed at its edges.

As described above, according to the present invention, a liquid crystal display panel for variable display patterns placed in front of the variable display device serves as a new machine part for performing game effects. In addition, preferably the base frame in front of the liquid crystal panel is of a background color. In this case, incident light on the base frame is hardly reflected in the liquid crystal panel. Therefore, new game effects can be implemented on the liquid crystal display panel, which helps to maintain the innovativeness of game effects. Furthermore, since incident light on the base frame is not reflected into the liquid crystal panel, it is possible to maintain the visibility of the liquid crystal panel and the variable display device behind it.

As described above, according to the present invention, the electric display device for variable display patterns placed in front of the variable display means serves as a new machine part for performing game effects. In addition, it is preferable to remove the corner portion of the periphery in the rear side of the window formed in the rear fixture. In this case, when the player observes the variable display device behind the electric display device, the player is prevented from viewing the corner portion of the periphery. Therefore, new game effects can be implemented on the panel of the electric display device, which helps to keep the innovation of game effects. And, because the corner portion of the periphery in the rear side of the window formed in the rear holder is invisible, the player thinks that the thickness of the rear holder is relatively thin, thus preventing recognition of the thickness of the electric display device completely.
