  Hereinafter, the gaming machine of the present invention will be described in more detail based on examples. FIG. 1 is a block diagram illustrating a pachinko machine using an effect control board 3 according to an embodiment. The illustrated pachinko machine has a main control board 1 for centrally controlling gaming operations, a symbol control board 2 for changing characters and symbols displayed on the liquid crystal display DISP, a speaker and a blinking operation of lamps. An effect control board 3 that realizes a sound effect and a lamp effect, a payout control board 4 that pays out a game ball, a launch control board 5 that launches a game ball, and a DC voltage to each part of the apparatus and each control board And a power supply board 6 for supplying a system reset signal SRST to the reset circuit.

The main control board 1, the symbol control board 2, the effect control board 3, and the payout control board 4 are each composed of a computer circuit having a one-chip microcomputer. And the symbol control board 2 and the production | presentation control board 3 are connected by the structure based on RS232C so that serial data TXD and RXD can be transmitted / received. Further, the main control board 1 transmits an appropriate control command (16-bit parallel data) to the symbol control board 2 and the payout control board 4 at a necessary timing, and based on this control command, the rendering operation and the game ball The payout operation is realized. In this embodiment, the control command has a 16-bit length and is transmitted separately every 8 bits.

The control command transmitted from the main control board 1 to the symbol control board 2 is an effect command CMD ₁ related to the effect operation, and the control command transmitted from the main control board 1 to the payout control board 4 is used for paying out the game ball. The payout command CMD ₂ concerned. More specifically, the effect command CMD ₁ transmitted to the symbol control board 2 is a common effect command CMD that is commonly used for the symbol effect on the liquid crystal display DISP, the sound effect by the speaker, and the lamp effect by the LED or the like. _1A and an individual effect command CMD _1B that is individually used for a symbol effect, a sound effect, or a lamp effect.

In this pachinko machine, when a game ball wins at the symbol start opening, the LCD display DISP starts to change the display symbol. After a reach effect, the variable symbol stops after a predetermined time, and whether or not it is a big hit state. Is fixed. Therefore, in this embodiment, for the common effect command CMD _1A that defines such a series of effect operations, only the result of whether or not it is a big hit state and the effect total time are specified, and the specific effect contents are not specified. It is transmitted to the symbol control board 2.

Then, in the symbol control board 2 that has received the common effect command CMD _1A , the specific effect content is selected and determined by effect lottery, and a new effect command CMD _1A ′ for specifying the determined content is transmitted to the effect control board 3. At the same time, the symbol changing operation on the liquid crystal display DISP is started in accordance with the determined contents. When the individual effect command CMD _1B , which is not related to the symbol effect on the liquid crystal display DISP and is specific to the sound effect or the lamp effect, is received, the symbol control board 2 transfers it to the effect control board 3 as it is.

By the way, in the case of a present Example, the production | presentation control board 3 is comprised by the production | presentation main board | substrate 7 used in common regardless of the difference in a model, and the production | presentation sub board | substrate 8 designed separately for every model. . As shown in the figure, the production main board 7 is connected to the plurality of decorative boards 10... 10 via the lamp relay board 9, and the control command (CMD _1A ′ or CMD _1B ) received from the symbol control board 2 is received. Based on this, an appropriate lamp production is realized. The production main board 7 specifies a series of audio information to be output based on the control command (CMD _1A ′ or CMD _1B ) received from the symbol control board 2 and drives the speaker via the production sub board 8. is doing.

  As shown in FIG. 1, in this embodiment, an effect switch 11 is connected to the effect sub-board 8. Although the usage method of this production | presentation switch 11 is not specifically limited, For example, it is used when resuming production | presentation operation | movement interrupted on the way. In such an embodiment, different effects can be realized depending on the timing at which the effect switch 11 is pressed. For example, in the state where the symbol effect is interrupted (the sound effect and the lamp effect are also interrupted as necessary First, it is conceivable to cause the player to press the effect switch 11.

  Then, the switch signal Vout is transferred as a serial signal from the effect sub board 8 to the effect main board 7 and is supplied as an interrupt signal IR to the CPU of the effect main board 7. It is possible to perform a unique performance. In addition, the pressing timing of the effect switch 11 and the contents of the effect determined thereby can be transmitted to the symbol control board 2 via the USART circuit of the effect main circuit 7.

The production main board 7 also drives the production motor M when necessary based on the control command (CMD _1A ′ or CMD _1B ) received from the symbol control board 2. Here, the effect motor M rotates, for example, an effect rotating body provided on the game board, and an advanced effect operation such as rotating the rotating body in association with the pressing operation of the effect switch 11 is possible. It becomes.

  FIG. 2 is a block diagram showing the production main board 7 shown in FIG. 1 in more detail. As shown in the figure, the production main board 7 includes a one-chip microcomputer 11 that controls the production control operation, a program ROM 12 that stores the control program, and a voice that is stored in a voice data ROM (phrase data ROM in the embodiment) 13. The audio reproduction LSI 14 is mainly configured to read and expand the compressed data and output the analog audio signals AOL and AOR together with the control signal PLAY.

  The internal configuration of the one-chip microcomputer 11 is as shown in detail in FIG. 3, and more specifically as shown in FIG. As shown, the one-chip microcomputer 11 includes a CPU core 11a, a RAM 11b, an interrupt controller 11c, an external bus interface 11d, a synchronous / asynchronous serial port (USART circuit) 11e, timer / counter circuits 11f and 11g, , And 40-bit parallel port 11h.

  Returning to FIG. 2 and continuing the description, in this embodiment, the control command received from the symbol control board 2 is sent to the parallel port (input) of the one-chip microcomputer 11 via the Schmitt trigger buffer (for example, SN74LV8151PWR) 15 serving as a buffer circuit. Set to port) 11h. The strobe signal STB from the symbol control board 2 is supplied to the interrupt controller 11c via the Schmitt trigger buffer 15, and the interrupt processing program is activated to acquire a control command.

  The CPU core 11a is configured to output dynamic lighting data from a parallel port (set as an output port) 11h in order to execute a lamp effect operation specified by the acquired control command. The output lighting data is output via a transistor array (M54562FP and M54585FP in the embodiment) 16a and 16b as drivers, and is supplied to the LED group mounted on the decorative substrate 10 in this embodiment. In this way, the production main board 7 outputs an 8 bit common signal and 8 bit blinking data with a margin so that it can be used in common regardless of the model, but an appropriate number of them outputs a game. It is selected and used according to the total number of LEDs arranged in the machine.

  The data bus of the one-chip microcomputer 11 is a D-type flip-flop as a driver (for example, SN74273 is 3 so that rotation of the effect motor M based on the control command received from the symbol control board 2 and blinking operation of the display lamp can be realized. ) 17. Then, 12 bits out of the output of the D-type flip-flop 17 are outputted as they are, and in this embodiment, they are used as drive data (Φ1 to Φ4) of the stepping motor as the effect motor M. On the other hand, 11 bits out of the output of the D-type flip-flop 17 are outputted via a driver (for example, six TND017SWs) 18 and are used as blinking data of the light emitting lamp in this embodiment.

  As described above, this production main board 7 is designed to have a margin so that it can be used in common regardless of the model, and is used for motor drive data (Φ1 to Φ4) × 3 and lamps. Of the blinking data, only the required number is used as appropriate. The output data from the one-chip microcomputer 11 is typically used as motor drive data or lamp blinking data, but may be used for other purposes.

  As shown in FIG. 2, 4-bit data can be input to the interrupt controller 11 c of the one-chip microcomputer 11 through a bus buffer (for example, SN74244) 19. However, in this embodiment, only the position detection signal (1 bit) of the effect motor M and the effect switch data Vout (1 bit) are used among the outputs of the bus buffer 19.

  Further, the output data TXD of the USART circuit 11e and the control data RTS (request to send) are supplied to the input terminal of the bus buffer 19, and the design is sent from the output terminal of the bus buffer 19 to the design control board 2. It is output as input data RXD and control data CTS (clear to send) of the control board 2. On the other hand, the output data TXD and control data RST (request to send) from the symbol control board 2 are sent via the bus buffer 19 to the input data RXD and control data CTS (clear to send) of the one-chip microcomputer 11. ) Is supplied to the USRAT circuit 11e.

  The system reset signal SRST supplied from the power supply board 8 shown in FIG. 1 is supplied to the reset circuit 20 shown in FIG. 2 and contributes to the reset operation of the CPU after the power is turned on. The system reset signal SRST is also supplied to the audio reproduction LSI 14 via the reset circuit 20, and the audio reproduction LSI 14 is also reset when the power is turned on.

  Here, the audio playback LSI 14 is not particularly limited as long as it compresses compressed audio data, but in this embodiment, an automatic performance LSI (Yamaha Corporation) incorporating a sequencer by an AMM (Amusement Music Compression) data decoder. YMZ770B) is used. This LSI includes an internal circuit as shown in FIG. 5, and operates based on a command received from a host CPU (a CPU core 11a of a one-chip microcomputer in this embodiment).

  In addition, since eight independent sequence phrases (phrase data decoding) can be simultaneously played back by eight sequencers (phrase data decode), the background sound that excites the gaming operation of the gaming machine can be reproduced as stereo sound, and whether or not it is a big hit It is also possible to reproduce the notice sound for notifying the final result in the middle of the production operation by superimposing it on the background sound independently of the left and right speakers.

  The reproduced sound from the automatic performance LSI can be output as a digital signal or an analog signal. In this embodiment, analog signals (AOL, AOR) are used. Further, when audio data is being reproduced, a PLAY signal is output from the automatic performance LSI. Therefore, the PLAY signal is used to control whether or not the analog amplifier (FIG. 6) is set in the MUTE state. is doing.

  FIG. 6 illustrates an example of the effect sub-control board 8. This effect sub-board 8 conveys a driver 50 (three Darlington sync drivers TD62064AF in the embodiment) receiving the output of the D-type flip-flop 17 of the effect main board 7 and a 4-bit signal to the effect main board 7. The Schmitt trigger circuit 51, the digital amplifier 52 and its associated circuit, and a serial transmission path 53 connected to the effect main board 7 or the symbol control board 2 are configured. However, in this embodiment, the serial transmission path 53 is not used, and the effect main board 7 and the symbol control board 2 are directly connected without the effect sub board 8.

  In this embodiment, only one 4-bit output among the outputs of the Darlington sink driver 50 is used to drive one effect motor M. Of the 4-bit data applied to the Schmitt trigger circuit 51, only 1 bit is used as the position detection signal of the effect motor M and only 1 bit is used as the switch signal Vout of the effect switch. Since such a configuration is adopted, it is possible to immediately cope with an increase in the production motor.

The digital amplifier 52 mounted on the effect sub-board 8 is not particularly limited as long as it performs an amplification operation by converting an analog signal into a digital signal such as a PWM (Pulse Width Modulation) wave. In this embodiment, TPA032D02 ( TI) CLASS-D AUDIO POWER AMPLIFIER is used. FIG. 7 shows the internal configuration, which has an amplification factor of about 25 dB.

  As described above, in this embodiment, since the digital amplifier 52 is used instead of the analog amplifier, the power consumption does not increase excessively even if a sound production with a large volume is executed. This is extremely effective in reducing the power consumption of a gaming hall where a large number of gaming machines are arranged.

  As mentioned above, although the usage method of the production main board | substrate 7 which concerns on an Example was demonstrated concretely, the concrete description content does not specifically limit this invention. For example, in the above embodiment, the production main board 7 is configured to receive the control command from the symbol control board 2, but instead of this configuration, the production main board 7 is the main control board as shown in FIG. 1 may receive a control command. In FIG. 8, the payout control board and the launch control board are not shown.

Also in the case of the configuration of FIG. 8, the effect main board 7 receives the common effect command CMD ₁ </ b _{> A} and the individual effect command CMD ₁ </ b> _B from the main control board 1. Then, the production main board 7 that has received the common production command CMD _1A selects and decides the specific production content by production lottery, and sends the production command CMD _1A 'for specifying the determined content via the production sub-board 8. While transmitting to the symbol control board 2, the sound effect and the lamp effect are started according to the determined content. On the other hand, the symbol control board 2 that receives the effect command CMD _1A ′ starts the symbol effect (variation operation) on the liquid crystal display DISP.

When the pachinko machine is configured as shown in FIG. 8, the effect sub-board 8 is configured as shown in FIG. 9, and the control command (effect command CMD _{1 A} ′) is sent to the symbol control board 2 through the Schmitt trigger buffer 53. ) And the strobe signal STB. In this case, even if a 16-bit control command is transmitted every 8 bits, the drive data for the stepping motor or the lighting signal directed to the indicator lamp is limited by the strobe signal STB, but the design control board 2 produces effects. Since there is no need to perform lottery, the control burden on the symbol control board 2 is reduced.

  As described above, in the pachinko machine according to each embodiment, the production control board 3 that realizes a series of production operations excluding the design production (including the lamp production and the voice production) is general-purpose regardless of the model change. The production main board 7 that can be used for the production and the production sub board 8 that is designed to be changed in accordance with the model change are separated. Therefore, when developing a new model, only a part of the production sub-board 8 needs to be changed. After that, it is possible to concentrate on software development, so that the development process can be greatly shortened. Further, when paying attention to the flow of control commands, it is possible to provide a symbol control board on the upstream side of the effect control board or a symbol control board on the downstream side, and the degree of freedom in designing the pachinko machine is increased.

  By the way, it is not always necessary to provide the symbol control board 2 on the upstream side or the downstream side of the effect control board 3 in view of the flow of the control command. As shown in FIG. The substrate 2 may be configured in parallel connection. Further, it is not always necessary to mount the lamp control unit and the sound control unit on the common board (production control board 3), and the production control board 3 is used for lamp control as shown in FIGS. It is also preferable to divide into a main board (first board) and a sub board (second board).

  In this case, as seen from the flow of the control command, as shown in FIG. 13B, the sound control board and the effect board 3 may be configured in parallel connection, or the lamp control board may be used as the sound control board. Alternatively, the audio control board may be subordinate to the lamp control board (FIG. 13C).

  The configuration of the entire gaming machine can be changed as appropriate as shown in FIGS. In the case of FIGS. 14 and 15, the effect sub board 8 is also used as a relay board for the power supply voltage, and the wiring can be made clear. In the case of FIG. 15, a signal from the upper plate button (production switch 11) is supplied to the symbol control board 2 through a serial communication line, and a part of the lamps is produced by the control of the symbol control board 2. The operation is realized.

  FIG. 16 shows an embodiment in which no symbol control board is present, and an effect medium (particularly a display medium) such as a dot matrix display or a liquid crystal display is directly controlled by the effect control board 3. In this case, the effect sub-board generates a voltage value for the display medium by the DC / DC converter. It is also preferable to connect the serial port of the production main board 7 to a display medium such as a dot matrix display via the production sub board 8.

  In all embodiments, examples of the effect medium driven by the effect sub-board 8 include a speaker, a motor, a solenoid, a lamp, a 7-segment display, and a dot matrix display. If a symbol control board is not required to provide a 7-segment display or a dot matrix display (see FIG. 16), it is necessary to provide an external output terminal on the effect sub-board 8 due to legal restrictions. is there.

  Finally, a pachinko machine to which the present invention is preferably applied will be described for confirmation.

A ball lending switch 32b for instructing lending of game balls for a predetermined amount, and a return switch 32c for instructing to return the card at the end of the game. On the upper part of the glass door 26, a big hit LED lamp P1 indicating a big hit state is arranged. In addition, in the vicinity of the big hit LED lamp P1, abnormality notification LED lamps P2 and P3 are provided to indicate a replenishment state or a full state of the lower plate.

  As shown in FIG. 12, the game board 25 is provided with a guide rail 33 formed of a metal outer rail and an inner rail in an annular shape, and a liquid crystal color display DISP is provided at the approximate center of the game area 25a inside. Has been placed. In addition, at a suitable place in the game area 25a, a symbol start opening 35, a big winning opening 36, a plurality of normal winning openings 37 (four on the right and left of the big winning opening 36), and a gate 38 which is two passage openings are arranged.
