In the conventional gaming machine, the sub control board is provided with a command signal output terminal and a selection signal output terminal for outputting a command signal and a selection signal to a display control circuit disposed on the display control board.
By the way, depending on the model of the gaming machine, there is a case where an effect specification by a light emitter such as an LED is adopted instead of an effect specification by a display device (decorative symbol display device). In this case, the command signal output terminal of the sub control board corresponding to the production specifications by the display device is not necessary. In gaming machines, it is prohibited to change the board terminal to an empty terminal, so it is necessary to replace the board with a sub-control board with a production specification by a light emitter.
Here, from the viewpoint of effective use of resources, there is an increasing demand for sharing the sub-control board. In addition, the sub-control board is being multilayered for the purpose of downsizing the board, and the cost of the sub-control board is high. From this point of view, there is a demand for sharing the sub-control board.
However, as described above, when the sub-control board of the effect specification by the display device is used for the effect specification by the light emitter, an empty terminal is generated at the command signal output terminal of the sub-control board. For this reason, the sub-control board cannot be shared.
The present invention was devised in view of the above points, and is a technology that can also be used as a sub-control board for different performance specifications while preventing the occurrence of empty terminals on the terminals of the board. The purpose is to provide.

In order to solve the above-mentioned problem, a first invention of the present invention has the structure described in claim 1.
The gaming machine of the present invention has at least a sub-control circuit that outputs a common sub-control signal and a selection signal based on a main control signal output from a main control circuit that controls the operation of the entire gaming machine. The sub control circuit is disposed on the sub control board. The sub control board is provided with a common sub control line for transmitting a common sub control signal in common, and a selection signal transmission line for transmitting a selection signal is individually arranged corresponding to the transmission destination of the selection signal. It is installed. Typically, a bus corresponds to the common sub control signal line. When outputting the individual sub control signal from the sub control circuit, the individual sub control line for transmitting the individual sub control signal is individually arranged corresponding to the output destination for outputting the individual sub control signal. . The common sub control signal line, selection signal line, and individual sub control signal line are typically formed as a wiring pattern.
In this specification, the “common sub-control signal” means a sub-control signal output to the common sub-control line, and typically corresponds to a sub-command signal such as a display command signal or a sound command signal. The common sub-control signal (sub-command signal) is composed of data (signal) of n bits (n is a positive integer of 1 or more), but is composed of data of 2 bits or more, typically 8 bits. The When the common sub control signal is transmitted in parallel, the number of common sub control lines is provided by the number of bits constituting the common sub control signal.
The selection signal output from the sub-control circuit is typically composed of 1-bit data (for example, “H” level or “L” level data). Note that a selection signal including a first selection signal and a second selection signal can be used to prevent malfunction due to noise or the like. In this case, when the first selection signal and the second selection signal satisfy a predetermined condition, for example, when both are at the “H” level, it is determined that the correct selection signal has been received.
The sub control board is provided with a common sub control signal output terminal and a selection signal output terminal for outputting a common sub control signal and a selection signal to the outside of the sub control board. The common sub control signal output terminal outputs a common sub control signal that transmits the common sub control signal line. A selection signal for transmitting a selection signal line corresponding to a control circuit arranged outside the control board is output from the selection signal output terminal. The mode of outputting the common sub control signal and the selection signal from the common sub control signal output terminal and the selection signal output terminal includes a mode of outputting via a relay circuit such as a transistor or an amplifier circuit.
For example, a display control board or a light emitter board can be connected to the sub-control board. These boards are provided with a common sub control signal output terminal disposed on the sub control board, a common sub control signal input terminal connected to the selection signal output terminal, and a selection signal input terminal. Preferably, the sub-control board is provided with an individual sub-control signal line and an individual sub-control signal output terminal for outputting the individual sub-control signal to the outside of the sub-control board, and the light emission connected to the sub-control board. An individual sub control signal input terminal connected to the individual sub control output terminal is disposed on the instrument board. The mode of outputting the individual sub control signal for transmitting the individual sub control signal line from the individual sub control signal output terminal includes a mode of outputting via a relay circuit such as a transistor or an amplifier circuit.
The light emitter substrate is provided with first and second light emitter connection terminals to which the light emitter is connected. Further, a current adjustment circuit is disposed on the light emitting substrate between the common sub control signal input terminal and the selection signal input terminal and one of the first and second light emitter connection terminals. Preferably, one of the first and second light emitter connection terminals to which the current adjustment circuit is connected is connected to the negative terminal (or ground terminal) of the DC power source, and the first and second light emitter connection terminals are connected. The other is connected to the positive terminal of the DC power supply.
The current adjustment circuit uses the common sub control signal input terminal to calculate the value of the current flowing through the light emitters connected to the first and second light emitter connection terminals without generating an empty terminal at the common sub control signal input terminal. Regardless of the common sub-control signal input to the input signal, the control signal is adjusted to be less than the lower lighting limit current value or higher than the lower lighting limit lower current value based on the selection signal input to the selection signal input terminal, Are configured so that the common sub-control signal for transmitting the signal does not change. The current adjustment circuit is typically configured by a resistor. The resistance value of the resistor of the current adjustment circuit is set in consideration of the voltage fluctuation of the DC power supply, the rated current of the light emitter, and the like.

According to the first aspect of the present invention, a light-emitting substrate that does not require a common sub-control signal is supplied with a selection signal input regardless of the sub-control signal input to the common sub-control signal input terminal. A current adjustment circuit for adjusting based on a selection signal input to the terminal is provided. Accordingly, even when the light emitter board on which the common sub control signal input terminal and the selection signal input terminal are arranged is connected to the sub control board on which the common sub control signal output terminal and the selection signal output terminal are arranged. In addition, it is possible to prevent the common sub control signal transmitted through the common sub control signal line from changing, and it is possible to prevent an empty terminal from being generated at the common sub control signal output terminal of the light emitter board.
Therefore, the sub-control board on which the common sub-control signal output terminal and the selection signal output terminal are arranged is commonly used for a gaming machine that produces an effect by the display device and a gaming machine that does not produce an effect by the display device. it can. Thereby, resource saving and cost reduction can be achieved.

The pachinko machine shown in FIG. 1 includes a main control board 10, a sub control board 20, a display control board 30, a lamp board 40, and the like.
The main control board 10 is provided with a main control circuit 11, a storage circuit 12 such as a ROM and a RAM, a display device driving device 13, and the like. Usually, the main control circuit 11 and the storage circuit 12 are integrally configured as a control IC.
Various input signals are input to the main control circuit 11. For example, a start winning ball detection signal indicating that a game ball has entered the start winning device, which is output from the start winning ball detection device, a game ball which is output from the special winning ball detection device, enters the special winning opening A special winning ball detection signal indicating that the game ball has been output, a game ball that is output from the winning ball detection device, and a game ball that is output from the winning ball detection device that indicates that the game ball has entered the grand winning device A winning ball detection signal or the like indicating that has entered the winning hole is input.
The main control circuit 11 outputs a main control signal based on the input signal and a control program stored in the storage circuit 12 and various random number generation programs.
For example, when a start winning ball detection signal is input, a lottery is performed by lottery means to determine whether the lottery result is a win (lottery result) and to determine an effect display time for notifying the lottery result. . Then, a main command signal including lottery result information indicating the determined lottery result and effect display time information indicating the effect display time is output to the sub-control circuit 21 as a main control signal. Further, based on the determined lottery result and the effect display time, a control signal for controlling the display device driving device 13 that drives the special symbol display device 14 is output as a main control signal. In addition, when the lottery result is a win, after the lottery result is rendered, an opening / closing member control signal is output to a large winning opening / closing member driving circuit that drives a large winning opening / closing member that opens / closes the large winning opening. Then, a jackpot gaming state that is advantageous to the player is generated.

Based on the above, a sub-control signal is output.
For example, on the basis of the lottery result information and the variable display time information, a decorative symbol and a variation pattern to be displayed on the decorative symbol display device 37 are determined, and symbol information indicating the determined decorative symbol, variation pattern information indicating the variation pattern, and the like are displayed. The display command signal (subcommand signal) that is included is output to the display control circuit 31 as a subcontrol signal.
Further, in order to produce a sound according to the determined variation pattern, a sound command signal (subcommand signal) including variation pattern information indicating the determined variation pattern is output to the sound source IC 23 as a sub-control signal. The sound source IC 23 outputs a sound generator drive signal to the speaker 24 based on the input sound command signal, and generates a sound corresponding to the variation pattern from the speaker 24.
Further, in order to produce an effect with light according to the determined variation pattern, a lamp control signal according to the determined variation pattern is output to the lamp drive circuit 25 as a sub-control signal. Based on the input lamp control signal, the lamp driving circuit 25 outputs a lamp driving signal to the corresponding lamp 26 (supplying direct current power to the lamp), and turns on or off the lamp 26 in accordance with the fluctuation pattern. . As the lamp 26, for example, a light emitter such as an LED is used.

The display control circuit 31 outputs a display control signal to the VDP 34 based on a sub-control signal output from the sub-control circuit 21, for example, a display command signal (sub-command signal) including symbol information, variation pattern information, and the like.
Based on the input display control signal, the VDP 34 reads predetermined symbol image information, character image information, background image information, etc. from the ROM of the storage circuit 35, and adjusts the size and arrangement position of each read image information. The bit map data corresponding to the display screen is created by combining them, and stored in the RAM of the storage circuit 35.

For example, when the winning determination random number matches the winning value (when the lottery result is winning), the special symbol is displayed on the special symbol display device 14 and the variable display time variation display corresponding to the variable display time determination random number. After that (including a mode in which the LEDs are sequentially turned on), the special symbols are stopped and displayed. On the other hand, when the winning determination random number does not match the winning value (when the lottery result is out of date), the special symbol is displayed on the special symbol display device 14 and the variable display time variation display corresponding to the variable display time determination random number. After that, the special symbol for the loss is displayed. In addition, you may comprise so that a winning special symbol and an extraordinary special symbol may be determined by lottery.

Further, the main control circuit 11 outputs a main command signal indicating a lottery result and a variable display time (a hit determination random number and a variable display time determination random number) to the sub control circuit 21 as a main control signal.
In addition, when the winning determination random number matches the winning value (when the lottery result is winning), the main control circuit 11 opens the large winning opening opening / closing member that opens and closes the large winning opening after the variable display time has elapsed. A control signal to be controlled is output, and the special winning opening opening / closing member is controlled to open for a predetermined time.
Then, when the game ball enters the special winning opening within this predetermined time and a special winning ball detection signal is input, the jackpot gaming state is entered, and a control signal for controlling the opening of the large winning opening / closing member is output. The big winning opening / closing member is closed when a set time has elapsed or when a predetermined number of game balls have entered the big winning opening (running a round). Each time the special winning ball detection signal is input, the round for controlling the opening of the special winning opening / closing member is executed until a predetermined number of rounds are reached. If a special winning ball detection signal is input during the round, the process proceeds to the next round.
Further, when the special winning ball detection signal is input and the jackpot gaming state is started, a main command signal indicating the start of the jackpot gaming state is output to the sub-control circuit 21 as a main control signal.
Further, when a winning ball detection signal indicating that a game ball has entered a winning device such as a start winning device, a grand winning device, a winning device or the like is input to the main control circuit 11, a number of games corresponding to the winning device. A main command signal instructing to pay out a ball is output as a main control signal to a prize ball control circuit (not shown).
The main control circuit 11 performs various other controls.

The sub control circuit 21 outputs various sub control signals based on the main command signal output as the main control signal from the main control circuit 11.
For example, when the main command signal output from the main control circuit 11 indicates that the lottery result is winning (when the winning determination random number matches the winning value), the winning design random number is read. The random number for symbol variation pattern corresponding to the variation display time indicated by the main command signal (the variation display time indicated by the random number for variation display time determination) is read. Then, the decorative symbol and the variation pattern to be displayed on the decorative symbol display device 37 are determined by the read random number for the winning symbol and the random number for the winning symbol variation pattern. On the other hand, when the main command signal indicates that the lottery result is out of order (when the winning determination random number does not match the winning value), the lost symbol determining random number is read and indicated by the main command signal. The random number for the off symbol variation pattern corresponding to the variation display time is read. Then, the decorative symbol and the variation pattern to be displayed on the decorative symbol display device 37 are determined based on the read symbol random number and the symbol variation random number.
Then, common sub-control is performed on a display command signal (subcommand signal) including symbol information indicating the determined decorative symbol (winning symbol or off symbol) and variation pattern information indicating a variation pattern (per symbol variation pattern or off symbol variation pattern). The signal is output to the display control circuit 31 as a signal.
When a display command signal (common sub control signal) is output from the sub control circuit 21 to the display control circuit 31, the following method is used.

The sub control circuit 21 outputs 8-bit data corresponding to the display command signal output to the display control circuit 31 from the common sub control signal output terminals A1 to A8 in parallel to the common sub control signal line. At the same time, the sub control circuit 21 outputs a selection signal (for example, “H” level selection signal) indicating that the display control circuit 31 is selected from the selection signal output terminal S1 to the selection signal line 1. At this time, a selection signal (for example, an “L” level selection signal) indicating that the sound source IC 23 is not selected is output from the selection signal output terminal S2.
A display command signal composed of 8-bit data output from the sub-control circuit 21 is output to the common sub-control signal input terminals A1 to A8 of the sound source IC via the common sub-control signal line, and the common sub-control signal is output. The signal is output to the base terminals of the control signal output NPN transistors Tr21a to Tr281h. Accordingly, the common sub control signal output terminals C21a to C31h are in a state corresponding to the data of each bit constituting the common sub control signal (a common sub control signal is output). For example, when the bit data of the common sub-control signal is at “H” level, the NPN transistor for outputting the common sub-control signal is in a conductive state, and the common sub-control signal output terminal is in the “ground state”. On the other hand, when the bit data of the common sub-control signal is “L” level, the NPN transistor for outputting the common sub-control signal is turned off, and the common sub-control signal output terminal is in the “open state”.
In this embodiment, since the positive terminal of the 12V DC power supply is connected to the common sub control signal input terminals C31a to C31h of the display control board 30 via the pull-up resistor R31b, the common sub control signal output terminal When the NPN transistor is non-conductive, the common sub-control signal output terminal is at “H” level.
The selection signal output from the selection signal output terminal S1 of the sub control circuit 21 is output to the base terminal of the selection signal output NPN transistor Tr21i via the selection signal line 1. As a result, the selection signal output terminal C21i is in a state corresponding to the selection signal. For example, when the selection signal is “H” level, the selection signal output terminal C21i is “grounded”, and when the selection signal is “L” level, the selection control signal output terminal C21i is “ Open state ".
In the present embodiment, the mode of “outputting a selection signal (for example, a selection signal of“ H ”level”) indicating selection ”is used as the mode of“ outputting a selection signal ”. In addition, an aspect of outputting a selection signal indicating that the signal is not selected (for example, a selection signal of “L” level) is used as an aspect of “not outputting a selection signal”.

The display control circuit 31 determines whether or not to take in the sub command signals (common sub control signals) input to the common sub control signal input terminals A1 to A8 according to the selection signal input to the selection signal input terminal S. To do.
For example, when the “H” level selection signal indicating that the display control circuit 31 is selected is output from the selection signal output terminal S1 of the sub control circuit 21, the selection signal output NPN transistor Tr21i is turned on. The selection signal output terminal C21i of the sub control board 20 and therefore the selection signal input terminal C31i of the display control board 30 are set to the “ground state” (“L” level). As a result, the selection signal input NPN transistor Tr31i is turned off. In this case, since the collector terminal of the PNP transistor Tr31i for selection signal input is connected to the positive terminal of the 3.3V DC power supply via a pull-up resistor (not shown), the selection signal input terminal S of the display control circuit 31 Becomes “open state” (“H” level).
On the other hand, when the “L” level selection signal indicating that the display control circuit 31 is not selected is output from the selection signal output terminal S1 of the sub control circuit 21, the selection signal output NPN transistor Tr21i. Is in a non-conductive state, and the selection signal input terminal C31i of the display control board 30 and thus the selection signal input terminal C31i of the display control board 30 is in the “open state” (“H” level). As a result, the selection signal input NPN transistor Tr31i becomes conductive, and the selection signal input terminal S of the display control circuit 31 becomes "grounded"("L" level).
The sub-control circuit 31 receives sub-command signals (common sub-control signals) input to the common sub-control signal input terminals A1 to A8 when the selection signal input terminal S is in the “ground state” (“L” level). The sub-command signal (common sub-control signal) input to the common sub-control signal input terminals A1 to A8 when the selection signal input terminal S is in the “open state” (“H” level) is not captured.
When a display command signal (common sub control signal) is output from the sub control circuit 21 to the display control circuit 31, it is confirmed that the sound source IC 23 is not selected from the selection signal output terminal S2 corresponding to the sound source IC 23. The sound source IC 23 does not take in the sub command signals (common sub selection signals) input to the common sub control signal input terminals A1 to A8.

The sub-control circuit 21 outputs a sound command signal (sub-command signal) for producing a sound corresponding to the determined variation pattern or a sound effect when the special gaming state occurs to the sound source IC 23 as a common sub-control signal. To do. For example, a sound command signal (subcommand signal) including variation pattern information indicating the determined variation pattern is output to the sound source IC 23.
The sound source IC 23 outputs a sound generator drive signal for driving the speaker 24 based on the input sound command signal (subcommand signal).
When outputting a sound command signal (subcommand signal) from the sub-control circuit 21 to the sound source IC 23, the following method is used.
The sub-control circuit 21 outputs 8-bit data corresponding to the sound command signal output to the sound source IC 23 from the common sub-control signal output terminals A1 to A8 in parallel to the common sub-control signal line. At the same time, a selection signal (for example, an “H” level selection signal) indicating that the sound source IC 23 has been selected is output from the selection signal output terminal S2 to the selection signal line 2. At this time, a selection signal (for example, an “L” level selection signal) indicating that the display control circuit 31 is not selected is output from the selection signal output terminal S1.
A sound command signal (subcommand signal) composed of 8-bit data output from the sub control circuit 21 is output to the common sub control signal input terminals A1 to A8 of the sound source IC 23 via the common sub control signal line. At the same time, it is output to the base terminals of the NPN transistors Tr21a to Tr21h for outputting the common sub control signal. Thus, the common sub control signal output terminals C21a to C21h are in a state corresponding to the data of each bit constituting the common sub control signal. That is, 8-bit data constituting the common sub control signal is input to the common sub control signal input terminals A1 to A8 of the display control circuit 31.
In this case, since the sound source IC 23 receives a selection signal (for example, a selection signal of “H” level) indicating that the sound source IC 23 is selected to the selection signal input terminal S, the common sub control signal input terminal A1. The sub-command signal input to .about.A8 is fetched.
On the other hand, in the display control circuit 31, a selection signal indicating that the display control circuit 31 is not selected is input to the selection signal input terminal S (for example, the selection signal input terminal S is in the “ground state”). The sub command signals input to the common sub control signal input terminals A1 to A8 are not captured.

Further, the sub control circuit 21 uses a lamp control signal for performing a light effect corresponding to the determined variation pattern or a light effect when a special gaming state is generated as an individual sub control signal (lamp drive circuit). To 25.
When a lamp control signal (individual sub control signal) is output from the sub control circuit 21 to the lamp driving circuit 25, the following method is used.
The sub-control circuit 21 determines which LED is turned on and which is turned off to produce a light effect corresponding to the determined variation pattern.
Then, the LEDs are turned on from the individual sub control signal output terminals D1 to Dm corresponding to the individual sub control signal lines connected to the LED driving transistors Tr-1 to Tr-m that drive the LEDs to be turned on. A lamp control signal (for example, an “H” level lamp control signal) is output as an individual sub-control signal. As a result, the LED driving transistors Tr-1 to Tr-m are turned on, and the resistor R40m, the LEDs 1 to LEDm, the individual sub control signal input terminals C41-1 to C41-m, the individual sub-controls from the positive terminal of the 12V DC power supply. A current flows to the ground terminal via the control signal output terminals C22-1 to C22-m and the LED driving transistors Tr-1 to Tr-m that are in the conductive state, and the LEDs 1 to LEDm are lit.
Further, the LED is turned off from the individual sub control signal output terminals D1 to Dm corresponding to the individual sub control signal lines connected to the LED driving transistors Tr-1 to Tr-m that drive the LED to be turned off. A control signal (for example, “L” level lamp control signal) is output as an individual sub-control signal. As a result, the LED driving transistors Tr-1 to Tr-m are turned off, and no current flows through the LEDs 1 to LEDm, so that the LEDs are turned off.

Next, a case where an effect using an LED and a speaker is performed without performing an effect using the display device will be described. When performing an effect using an LED and a speaker, as shown in FIG. 3, a lamp substrate (light emitter substrate) 50 and a speaker 24 are connected to the sub-control substrate 20.
Here, the sub-control board 20 has the same configuration as that of the sub-control board 20 shown in FIG.

A connector is disposed on the lamp substrate 50.
In FIG. 3, a connector C51 connected to a connector C21 for outputting a subcommand signal (common subcontrol signal) and a selection signal of the subcontrol board 20, and a lamp drive signal (individual subcontrol signal) of the subcontrol board 20 ) And the connectors C55 and C56 connected to the power supply connectors C25 and C26 of the sub control board 20 are disposed. Further, a connector C54 to which the LEDs 1 to LEDm are connected and a connector C53 to which the additional LEDx is connected are provided.
Each connector is provided with a terminal. In the present embodiment, the connector C51 includes common sub control signal output terminals C21a to C21h provided on the connector C21 of the sub control board 20 and common sub control signal input terminals C51a to C21i connected to the selection signal output terminal C21i. C51h and a selection signal input terminal C51i are provided.
The connector C52 has individual sub control signal input terminals C52-1 to C52-m connected to the individual sub control signal output terminals C22-1 to C22-m provided on the connector C22 of the sub control board 20. Is provided.

Further, the connector C54 includes a first LED connection terminal C54-1a to C54-ma and a second LED connection terminal C54-, which constitute an LED connection terminal pair (LED power supply terminal pair) to which the LEDs 1 to LEDm are connected. b to C54-mb are provided. The first LED connection terminal and the second LED connection terminal are connected to the positive terminal and the negative terminal of the 12V DC power supply. In FIG. 3, the first LED connection terminals C54-1a to C54-ma are connected to the positive terminal of the 12V DC power supply via the overcurrent protection resistor R50m, and the second LED connection terminals C54-1b to C54 are connected. -Mb is connected to the common sub control signal input terminals C52-1 to C52-m, the common sub control signal output terminals C22-1 to C22-m, and the common sub control signal output NPN transistors Tr-1 to Tr-m. Connected to the ground terminal.
In addition, the connector C53 is provided with a first LED connection terminal C53a and a second LED connection terminal C53b that constitute an LED connection terminal pair (LED power supply terminal pair) to which the additional LEDx is connected. The first LED connection terminal C53a and the second LED connection terminal C53b are connected to the positive terminal and the negative terminal of the 12V DC power supply. In FIG. 3, the first LED connection terminal C53a is connected to the positive terminal of the 12V DC power source via the overcurrent protection resistor R50x, and the second LED connection terminal C53b is connected to the current adjustment circuit 51 described later. Connected to the negative terminal of the 12V DC power supply.
The LEDx is composed of one or a plurality of LEDs.
In this embodiment, LEDx, LED1 to LEDm42 correspond to the “light emitter” of the present invention, the lamp substrate 50 corresponds to the “light emitter substrate” of the present invention, and the first LED connection terminal C53a and the second LED The LED connection terminal C53b corresponds to the “first and second light emitter connection terminals” of the present invention, and the first LED connection terminals C54-1a to C54-ma and the second LED connection terminals C54-1b to C54- mb corresponds to “third and fourth light emitter connection terminals” of the present invention.

As a lamp drive signal (light emitter drive signal) for turning on or off the LED x, a selection signal (selection signal for selecting the display control circuit 31 in FIG. 2) output from the selection signal output terminal C21i of the sub-control board 20 is used. Can be used.
Here, as described above, in the gaming machine, the terminal of the board cannot be an empty terminal. For this reason, the common sub control signal input terminals C51a to C51h provided in the connector C51 of the lamp substrate 50 cannot be set to the open state.
Further, common sub control signal input terminals C51a to C51h provided on the connector C51 of the lamp substrate 50 have each bit constituting the sub command signal (common sub control signal) transmitted through the common sub control signal line. Data is input via common sub control signal output terminals C21a to C21h provided on the connector C21 of the sub control board 20. Therefore, the sub-command signal (common sub-control signal) transmitted through the common sub-control signal line is affected by the current flowing through the common sub-control signal input terminals C51a to C51h provided on the connector C51 of the lamp board 50. It is necessary to process the common sub control signal input terminals C51a to C51h so as not to receive.

In the present embodiment, the second LED connection terminal C53b of the first LED connection terminal C53a and the second LED connection terminal 53b to which the additional LEDx is connected and the common sub-control provided in the connector C51. A current adjustment circuit 51 is provided between the signal input terminals C51a to C51h and the selection signal input terminal C51i.
The current adjustment circuit 51 includes a first resistor R51a to an eighth resistor R51h and a first resistor R51a disposed between the sub control signal input terminals C51a to C51h and the second LED connection terminal C53b. ˜Eighth resistor R51h and the second LED connection terminal C53b are configured by a ninth resistor R51i disposed between the connection point (common connection point) and the selection signal input terminal C51i.
As for the resistance values of the first resistor R51a to the ninth resistor R51i of the current adjustment circuit 51, a selection signal in which LEDx is not selected (LEDx is turned off) is input to the selection signal input terminal C51i of the connector C51. At this time, for example, a selection signal of “L” level is output from the selection signal output terminal S1 (selection signal output terminal corresponding to the display control circuit 31 in FIG. 2) S1 of the sub control circuit 21 to select the selection signal. When the output NPN transistor Tr21i is in a non-conductive state and the selection signal output terminal C21i and the selection signal input terminal C51i are in the “open state” (“H” level), the first LED connection terminal C53a and the second LED connection The value of the current flowing through the LED x connected to the terminal C53b is less than the minimum current value that can be turned on for the LED x (the LED x is turned off) So that in), is set. At this time, the value of the current flowing through the LEDx can be turned on regardless of the subcommand signals (common subcontrol signals) input to the common subcontrol signal input terminals C51a to C51h provided in the connector C51. It is set to be less than the minimum current value (so that the LED x is kept off regardless of the sub-command signal).
When a selection signal for selecting LEDx (lighting LEDx) is input to the selection signal input terminal C51i of the connector C51, for example, the selection signal output terminal S1 corresponding to LEDx of the sub-control circuit 21. When the selection signal of “H” level is output from the NPN transistor Tr21i for selection signal output and the selection signal output terminal C21i and the selection signal input terminal C51i are in the “ground state” (“L” level), The value of the current flowing through the LEDx connected to the first LED connector C53a and the second LED connection terminal C53b is set to be equal to or greater than the minimum current value that can be lit up of the LEDx (LEDx is lit). The At this time, the value of the current flowing through the LEDx can be turned on regardless of the subcommand signals (common subcontrol signals) input to the common subcontrol signal input terminals C51a to C51h provided in the connector C51. It is set so as to be equal to or greater than the minimum current value (so that LEDx is kept lit regardless of the sub-command signal).

That is, the current adjustment circuit 51 uses the selection signal input to the selection signal input terminal C51i regardless of the subcommand signal (common subcontrol signal) input to the common subcontrol signal input terminals C51a to C51h. It is configured to adjust the value of the current flowing through the LEDx connected to the LED connection terminal C53a and the second LED connection terminal C53b (so that the LEDx is turned on or off).
As a result, the common sub control signal input terminals C51a to C51h can be prevented from becoming empty terminals, and the common sub control signal transmitted through the common sub control signal line is not changed.
The resistance values of the first resistor R51a to the ninth resistor R51i of the current adjustment circuit 51 can be set as appropriate. For example, when the resistance value of the overcurrent protection resistor R50x is set to 560Ω, the resistance values of the first resistor R51a to the eighth resistor R51h are set to 6.8 kΩ, and the resistance value of the ninth resistor R51i is set to 10Ω. can do. The resistances of the first resistor R51a to the eighth resistor R51b are preferably large.
In addition, the current adjustment circuit 51 can use various other configurations.
The operation using the LEDs 1 to LEDm and the operation using the speaker 24 are as described above.

As described above, in the present embodiment, the sub-control board 20 to which the display control board 30 can be connected (having the common control signal output terminal and the selection signal output terminal) is replaced with the lamp board (light emission) instead of the display control board 30. Device board) 50 can be connected. Thereby, the sub-control board 20 can be used as a gaming machine having a specification using a display device (decorative symbol display device) and a light emitter and a specification having a specification using a light emitter without using a display device. Since they can also be used, resources can be saved and costs can be reduced.
In addition, the current flowing through the lamp substrate (light emitter substrate) 50 and the LED x (light emitter) 42 is supplied to the selection signal input terminal C51i regardless of the common sub control signal input from the common sub control signal input terminals C51a to C51h. A current adjustment circuit 51 that adjusts the value according to the input selection signal is provided. Thus, the common sub control signal transmitted through the common sub control signal line is not affected, and the common sub control signal output terminal of the sub control board 20 and the common sub control signal input terminal of the lamp board 50 are vacant terminals. Can be prevented.

Incidentally, noise or the like entering the signal line may cause a noise signal to be transmitted to the signal line or a signal transmitted through the signal line to change. When such a noise signal or signal change occurs, the control circuit may malfunction. For example, there is a possibility that the display control circuit malfunctions and the winning decorative symbol is erroneously displayed even though the lottery result is not a win, or the decorative ornament symbol is erroneously displayed although the lottery result is a hit. If such erroneous display is performed, there is a possibility that the interest of the player in the game will be reduced. For this reason, it is necessary to prevent such a malfunction.
A second embodiment having a configuration for preventing the display control circuit from malfunctioning due to noise or the like will be described below. In this embodiment, the sub control circuit outputs a selection signal composed of the first selection signal and the second selection signal to the display control circuit, and the display control circuit outputs the first selection signal and the second selection signal. It is determined whether or not an erroneous signal is input depending on whether or not the selection signal satisfies a predetermined condition.

At the same time, it is output to the base terminals of the NPN transistors Tr121a to Tr121h for outputting the common sub control signal. Further, the first selection signal for determining whether or not the display control circuit 131 is selected is the base terminal of the selection signal output NPN transistor Tr121i from the first selection signal output terminal S1a via the selection signal line 1a. The second selection signal output to is output from the second selection signal output terminal S1b to the base terminal of the selection signal output NPN transistor Tr121j via the selection signal line 1b.

The selection signal is output from the second selection signal output terminal S2b to the selection signal input terminal Sb of the sound source IC 123 via the selection signal line 2b.
In the present embodiment, the sub control circuit 121 outputs the same selection signal from the first and second selection signal output terminals S1a and S1b, and outputs the same selection signal from the selection signal output terminals S2a and S2b. For example, both “H” level selection signals or both “L” level selection signals are output.

The display command signal is output to the common sub control signal input terminals A1 to A8 of the sound source IC 123 via the common sub control line, and is also output to the base terminals of the NPN transistors Tr121a to Tr121h for outputting the common sub control signal. . Accordingly, the common sub control signal output terminals C121a to C121h, and thus the common sub control signal input terminals C131a to C131h, are in a state corresponding to each bit of the display command signal.
At the same time, the sub control circuit 121 selects a selection signal (for example, “H” level) indicating that the display control circuit 131 is selected from the first and second selection signal output terminals S1a and S1b corresponding to the display control circuit 131. Are output to the base terminals of the NPN transistors Tr121i and Tr121j for outputting the first and second selection signals via the first and second selection signal lines 1a and 1b. As a result, the first and second selection signal output terminals C121i and C121j, and thus the first and second selection signal input terminals C131i and C131j, are in a state corresponding to the level of the selection signal.
At this time, selection signals (for example, “L” level selection signals) indicating that the sound source IC 123 is not selected are output from the first and second selection signal output terminals S2a and S2b corresponding to the sound source IC 123. ing.

The display control circuit 131 determines whether or not the selection signals input to the first and second selection signal input terminals S1a and S1b satisfy a predetermined condition. For example, whether or not a selection signal (for example, an “H level” selection signal) indicating that the display control circuit 131 is selected is input to the first and second selection signal input terminals S1a and S1b. Is determined. If the selection signals input to the first and second selection signal input terminals S1a and S1b indicate that the display control circuit 131 is selected, the common sub control signal input terminal A1. A display command signal (subcommand signal) input as a common subcontrol signal is taken in to A8. On the other hand, when the selection signal input to one of the first and second selection signal input terminals S1a and S1b indicates that the display control circuit 131 is not selected, the common sub control signal input The display command signal input to the terminals A1 to A8 is not captured.
When outputting a common sub control signal to the sound source IC 123, the sub control circuit 121 sends a sound command signal (sub command signal) as a common sub control signal from the common sub control signal output terminals A1 to A8 to the common sub control signal line. Is output. The sound command signal is output to the common sub control signal input terminals A1 to A8 of the sound source IC 123 via the common sub control line, and is also output to the NPN transistors Tr121a to Tr121h for outputting the common sub control signal. At the same time, the sub-control circuit 121 first and second of the sound source IC 123 from the first and second selection signal output terminals S2a and S2b corresponding to the sound source IC 123 via the first and second selection signal lines 2a and 2b. A selection signal (for example, an “H” level selection signal) indicating that the sound source IC 123 is selected is output to the second selection signal input terminals Sa and Sb.
The operation of the sound source IC 123 is the same as that of the display control circuit 131.

Thus, in the present embodiment, the sub control circuit 121 outputs a selection signal composed of the first and second selection signals when outputting the common sub control signal. The display control circuit reads the common sub control signal only when the first and second selection signals satisfy a predetermined condition.
Here, the selection signal line for transmitting the selection signal and the common sub-control signal line for transmitting the common sub-control signal are often arranged at close positions. For this reason, the determination result of whether or not noise is mixed in the selection signal that transmits the selection signal line is also the determination result of whether or not noise is mixed in the common sub control signal that transmits the common sub control signal. Can be used. Therefore, by determining whether or not noise is mixed in the selection signal, it is determined whether or not there is a possibility that a display command signal including noise is input to the display control circuit 131, that is, the display control circuit. It is possible to determine whether or not 131 may malfunction.
Thereby, in this Embodiment, it can prevent that the decoration symbol different from a lottery result is displayed on the display apparatus (decoration pattern display apparatus) 137. FIG.
The same applies to the operation of the sound source IC 123.

Next, a case where an effect using an LED and a speaker is performed without performing an effect using the display device will be described. When performing an effect using an LED and a speaker, a lamp substrate (light emitter substrate) 150 and a speaker 124 are connected to the sub control substrate 120 as shown in FIG.
Here, the sub control board 120 has the same configuration as that of the sub control board 120 shown in FIG.

A connector is disposed on the lamp substrate 150. In FIG. 5, a connector C151 connected to a connector C121 that outputs a common sub-control signal and a selection signal, a connector C152 connected to a connector C122 that outputs an individual sub-control signal, and connectors C125 and C126 that supply a 12V DC power supply. Connectors C155 and C156 to be connected are provided. A connector C154 for connecting LEDs 1 to LEDm and a connector C153 for connecting LEDx are provided.
Each connector is provided with a terminal. The connector C151 includes sub-control signal output terminals C121a to C121h provided on the connector 121 of the sub-control board 120, and sub-control signal input terminals C151a to C151a connected to the first and second selection signal output terminals C121i and C121j. C151h and first and second selection signal input terminals C151i and C151j are provided.
The connector C152 is provided with individual sub-control signal input terminals C152-1 to C152-m connected to the individual sub-control signal output terminals C122-1 to C122-m provided on the connector C122 of the sub-control board 120. ing.
The connector C154 includes a first LED connection terminal C154-1a to C154-ma and a second LED connection terminal C154-1b to C154, which are LED connection terminal pairs (LED power supply terminal pairs) to which the LEDs 1 to LEDm are connected. -Mb is provided. The first LED connection terminals C154-1a to C154-ma are connected to the positive terminal of the 12V DC power supply via the overcurrent protection resistor R150m, and the second LED connection terminals C154-mb to C154-mb are Connected to the ground terminal.
The connector C153 is provided with a first LED connection terminal C153a and a second LED connection terminal C153b, which are LED connection terminal pairs (LED power supply terminal pairs) to which additional LEDs x are connected. The first LED connection terminal C153a is connected to the positive terminal of the 12V DC power source via the overcurrent protection resistor R150x, and the second LED connection terminal C153b is connected to the ground terminal via the current adjustment circuit 151. Has been.

One of the common sub control signal input terminals C151a to C151h, the first and second selection signal input terminals C151i and C151j provided in the connector C151 (in FIG. 5, the first selection signal input terminal C151i), the first and second A current adjustment circuit 151 is disposed between one of the second LED connection terminals C153a and C153b (in FIG. 5, the second LED connection terminal C153b).
In the present embodiment, the current adjustment circuit 151 includes a first resistor R151a to an eighth resistor R151h disposed between the sub control signal input terminals C151a to C151h and the second LED connection terminal C153b. The ninth resistor disposed between the connection point (common connection point) of the first resistor R151a to the eighth resistor R151h and the second LED connection terminal C153b and the first selection signal input terminal C151i. The resistor R151i is used.
As for the resistance values of the first resistor R151a to the ninth resistor R151i of the current adjustment circuit 151, a selection signal in which LEDx is not selected (LEDx is turned off) is input to the first selection signal input terminal C151i of the connector C151. For example, the selection signal output terminal corresponding to LEDx (in FIG. 4, the selection signal output terminal corresponding to the display control circuit 131) S1a of the sub-control circuit 121 outputs an “L” level selection signal. When the selection signal output NPN transistor Tr121i is non-conductive and the selection signal output terminal C121i and the selection signal input terminal C151i are in the “open state” (“H” level), the first and second LED connection terminals The value of the current flowing through the LEDx connected to C153a and C153b is less than the minimum current value that can be turned on for the LEDx. Sea urchin is (LEDx is so turned off) setting. At this time, the value of the current flowing through the LED x is less than the minimum litable current value of the LED x regardless of the common sub control signal input to the common sub control signal input terminals C151a to C151h provided in the connector C151. So that the LED x is kept off regardless of the common sub-control signal.
When a selection signal for selecting LEDx (lighting LEDx) is input to the first selection signal input terminal C151i of the connector C151, for example, a selection signal corresponding to LEDx of the sub control circuit 121 An “H” level selection signal is output from the output terminal S1a, the selection signal output NPN transistor Tr121i is in a conductive state, and the selection signal output terminal C121i and the selection signal input terminal C151i are in a “ground state” (“L” level). Is set so that the value of the current flowing through the LEDx connected to the first and second LED connection terminals C153a and C153b is equal to or greater than the minimum illuminable current value of the LEDx (LEDx is lit). Is done. At this time, the value of the current flowing through the LEDx is equal to or greater than the minimum illuminable current value of the LEDx regardless of the common subcontrol signal input to the common subcontrol signal input terminals C151a to C151h provided in the connector C151. (So that the LED x is kept on regardless of the common sub-control signal).
In the configuration shown in FIG. 5, the value of the current flowing through the LED x is determined by the values of the overcurrent protection resistor R150x and the first to ninth resistors R151a to R151i.

That is, the current adjustment circuit 151 has the first and second input signals depending on the selection signal input to the first selection signal input terminal C151i regardless of the common subcontrol signal input to the common subcontrol signal input terminals C151a to C151h. The LED connection terminals C153a and C153b are configured to adjust the value of the current flowing through the LEDx connected thereto.
As a result, the common sub control signal input terminals C151a to C151h can be prevented from becoming empty terminals, and the common sub control signal transmitted through the common sub control signal line can be prevented from changing.
The resistance values of the first resistor R151a to the ninth resistor R151i of the current adjustment circuit 151 are independent of the common sub control signal input to the common sub control signal input terminals C151a to C151h, and the first selection signal input terminal C151i. In accordance with the selection signal input to, the value of the current flowing through the LED x can be appropriately selected within a range in which the value can be adjusted to be less than the minimum lightable current value or greater than the minimum lightable current value. Note that as the first resistor R151a to the eighth resistor R151g, it is preferable to use resistors having high resistance values.

Furthermore, the other of the first and second selection signal input terminals C151i and C151j (the selection signal output terminal not connected to the current adjustment circuit 151), in the present embodiment, the second selection signal input terminal C151j is The current flowing through the additional LEDx is bypassed (or the terminal voltage of the additional LEDx is adjusted to be less than the minimum voltage value that can be lit).
In the present embodiment, the bypass circuit is configured by an NPN transistor Tr115j for the bypass circuit. The collector of the NPN transistor Tr115j for the bypass circuit is the other of the first and second LED connection terminals 153a and 153b to which the additional LEDx is connected (the LED connection terminal that is not connected to the current adjustment circuit 151). ), The emitter terminal is connected to the ground terminal, the base terminal is connected to the positive terminal of the 12V DC power source via resistors R115jb and R115ja (pull-up resistor), and the second terminal is connected to the second terminal via resistor R115jb. To the selection signal input terminal C151j.
Thereby, when the second selection signal input terminal C151j is in a state (for example, “ground state”) indicating that the LED x is not selected, the bypass NPN transistor Tr115j is turned on, and the bypass NPN transistor A bypass circuit constituted by Tr 115j is formed, and a current to LEDx flows through this bypass circuit. At this time, the value of the current flowing through the bypass NPN transistor Tr115j is limited by the overcurrent protection resistor R150x. In this case, even if a selection signal is input to the first selection signal input terminal C151i due to noise or the like, the LED x does not light up.
Therefore, when the second selection signal input terminal C151j is in a state where the LED x is not selected, it is possible to prevent the LED x from erroneously lighting due to noise or the like.

Here, in the present embodiment, the collector terminal of the bypass NPN transistor Tr115j is connected to the positive terminal of the 12V DC power supply among the first and second LED connection terminals C153a and C153b to which the LEDx is connected. It is connected to the first LED connection terminal C153a. Therefore, when the second selection signal input terminal C151j is in a state (for example, “open state”) indicating that the LED x is selected, the common sub control signal line is transmitted even if a current flows through the bypass circuit. The common sub-control signal does not change.
On the other hand, when the second selection signal input terminal C151j is in a state (for example, “open state”) indicating that the LED x is selected, the bypass NPN transistor Tr115j is turned off. In this case, the current flowing through the LEDx is adjusted by the first selection signal input to the first selection signal input terminal C151i. At this time, the change of the common sub control signal transmitted through the common sub control signal line is prevented by the first resistors R151a to R151h.

Next, an operation when the lamp substrate 150 and the speaker 124 are connected to the sub control substrate 120 will be described.
That the LED x is not selected from the first and second selection signal output terminals (selection signal output terminals corresponding to the display control circuit 131 in FIG. 4) S1a and S1b of the sub-control circuit 121 corresponding to LEDx. When a selection signal (for example, a selection signal of “L” level) is output, the NPN transistors Tr121i and Tr121j for outputting the first and second selection signals are in a non-conductive state. As a result, the first and second selection signal output terminals C121i and C121j, and thus the first and second selection signal input terminals C151i and C151j are in the “open state”.
As a result, the bypass transistor Tr115j is turned on to form a bypass circuit. By this bypass circuit, the current value of the current flowing through the LEDx connected to the first and second LED connection terminals C135a and C135b can be turned on. Limited to less than current value. Further, the value of the current flowing through the LED x is also adjusted to be less than the minimum illuminable current value by the current adjustment circuit 151. Therefore, the LED x is surely turned off. In this case, regardless of the common sub control signal input to the common sub control signal input terminals C151a to C151h, the value of the current flowing through the LED x is adjusted to be less than the minimum illuminable current value, and the common sub control line is transmitted. The common sub control signal does not change.

  On the other hand, a selection signal (for example, a selection signal of “H” level) indicating that LEDx is selected from the first and second selection signal output terminals S1a and S1b corresponding to LEDx of the sub control circuit 121. When the signal is being output, the NPN transistors Tr121i and Tr121j for outputting the first and second selection signals become conductive. In this case, since the bypass transistor Tr115j is in a non-conductive state, a bypass circuit is not formed. Then, the value of the current flowing through the LEDx connected to the first and second LED connection terminals C135a and C135b is adjusted by the current adjustment circuit 151 to be equal to or greater than the minimum lightable current value. Therefore, the LED x is surely turned on. In this case, regardless of the common sub-control signal input to the common sub-control signal input terminals C141a to C141h, the value of the current flowing through the LEDx is adjusted to be equal to or greater than the minimum lightable current, and the common sub-control line is transmitted. The sub control signal does not change.

In the present embodiment, when the sub control circuit 121 outputs a common sub control signal (sub command signal) to the display control circuit 131, the display control circuit 131 displays a selection signal composed of the first and second selection signals. Output to. The display control circuit 131 reads the common sub control signal when the first and second selection signals satisfy a predetermined condition. Thereby, it is possible to prevent the display control circuit 131 from malfunctioning due to noise or the like and displaying a decorative symbol different from the lottery result on the display device (decorative symbol display device).
Further, in the lamp substrate (light emitter substrate) 150, when an additional LED x is not selected, a bypass circuit that bypasses the current flowing through the LED x is formed by one of the first and second selection signals. Thereby, when LEDx is not selected, the value of the current flowing through LEDx can be reliably suppressed to be less than the minimum current value that can be lit of LEDx, and the light emitter can be prevented from being turned on erroneously. .
In addition, the current adjustment circuit 151 adjusts the value of the current flowing through the LED x to be equal to or greater than the minimum illuminable current value or less than the minimum illuminable current value by the selection signal regardless of the common sub control signal output from the sub control circuit 121. Is done. Thus, even when the lamp board 150 is connected to the sub control board 120, the common sub control signal transmitted through the common sub control line is not affected, and the common sub control signal input terminals C151a to C151h have empty terminals. Can be prevented.
