Abstract

PROBLEM TO BE SOLVED: To provide a game machine for preventing fraudulent practice, such as diversion of a circuit board, and allowing a circuit board of an identical wiring pattern to be shared.SOLUTION: The game machine includes a circuit board (main board 535), where a conductive pattern as wiring is formed on an insulating base board 571, and displays, on the circuit board, an identification marker for identifying the circuit board by display of a conductive pattern not affected by a conductive state or display for having the conductive pattern face a base board surface. In the game machine, there are formed a plurality of identification markers (identification markers 581, 582) for identifying the circuit board, there are formed shield parts (shield layer 575 or 576) for shielding the plurality of formed identification markers, other than identification markers for identifying the circuit board, to be hardly identified, and the circuit board is identifiable by unshielded identification markers.

Description

  The present invention relates to a gaming machine in which an identification mark is displayed on a circuit board.

  A gaming machine such as a pachinko machine or a pachislot machine has a circuit board called a game control board or a main board, and controls the game including the progress of the game and the like by the main board. This main board has a predetermined wiring pattern formed on an insulative base board, and a microcomputer for a game machine (CPU, ROM for storing a game program, a RAM for temporarily storing data, etc.) (Hereinafter referred to as a microcomputer).

  A circuit board such as this main board can be used for other gaming machines (for example, a main board with a different wiring program, even if the wiring pattern is the same), and a prize ball can be illegally obtained. There is a possibility that it can be used for illegal activities. Therefore, various identification signs are displayed on the circuit board in order to identify such a fraud so as to identify the circuit board. For example, an identification mark that identifies the manufacturer of a gaming machine that uses the circuit board, an identification mark (management number) that identifies the model of the gaming machine that uses the circuit board, and the like are displayed on the circuit board. .

  By the way, if the identification mark displayed on the circuit board can be easily erased, it is difficult to find the aforementioned fraud. For example, in a configuration in which the identification mark is formed on the surface of the base substrate by a method such as silk printing, illegal acts such as erasing the proper identification mark, newly forming a different identification mark, and diverting the circuit board There is a risk that it could be done without being discovered. In particular, if the wiring patterns and the like are the same, even if the game programs are different, the identification mark is changed, so that the appearance cannot be distinguished.

  Therefore, as in the case of the wiring pattern, a circuit board formed by a conductor layer of a circuit board and covered with an insulating film (protective film) is disclosed in Patent Document 1. In the case of this circuit board, the identification mark is printed on the base board in the same manner as the wiring pattern, and the base board is entirely covered with an insulating film, so that the identification mark cannot be easily erased later. As a result, when a similar main board used in other gaming machines is diverted or modified, it is possible to easily detect fraud such as diversion or modification by checking the identification mark, thereby preventing fraud. be able to.

  However, if the identification mark cannot be easily erased, even if the hardware configuration of the circuit board excluding the identification mark is the same, the circuit board can be used as the same if the identification mark is different due to different game machine models. There is a problem that productivity is not good. This is because, in recent pachinko machines and the like, the sub-control board that controls the liquid crystal display device controls speakers, lamps, movable parts for decoration, etc., and the main board sends control commands to the sub-control board. Thus, the movable part and the like are indirectly controlled. For this reason, the hardware configuration such as the wiring pattern of the main board is the same regardless of the model. By installing a game program for each model in the gaming machine microcomputer, the main board is technically different from model to model. Can be shared. However, if the identification mark that differs depending on the model or the like cannot be erased, the circuit board cannot be shared only by the difference in the identification mark.

  In particular, in recent years, as a gaming machine sales strategy, a gaming machine manufacturer has registered a second brand manufacturer with a group company, the direction of the manufacturer brand gaming machine that forms the core of the group, and second brand gaming. The direction of the machine is different and the sales channel is expanded. In such a group company, it is possible to use it in different brands (manufacturers) / models of circuit boards that can be used in common, but in order to prevent fraud, the brands (manufacturers) / It must be displayed for each model, and even though the wiring patterns are the same and can be shared with each other, circuit boards are created for different brands (manufacturers) and models, which is efficient. Not productive. If it can be shared, it can be reused and discarded due to inventory can be suppressed, and mass production is possible and costs can be reduced, but this has not been realized.

  In view of the above, an object of the present invention is to provide a gaming machine that can prevent an illegal act such as diversion of a circuit board and can share a circuit board having the same wiring pattern.

The gaming machine according to claim 1,
A circuit board having a conductive pattern formed as a wiring on an insulating base board is provided, and the circuit board is displayed by a conductive pattern not related to the conductive state or by displaying the base substrate surface from the conductive pattern, In a gaming machine that displays an identification mark that can identify the circuit board,
Forming a plurality of identification marks on the circuit board to identify the circuit board;
The plurality of formed identification signs are concealed to be difficult to identify except for an identification sign for specifying the circuit board, and the circuit board can be specified by the identification mark that is not concealed. .

  According to the present invention, since the identification mark is clearly shown on the circuit board by the conductive pattern and by facing the base substrate surface from the conductive pattern, it can be ensured that the identification mark cannot be easily erased. . Moreover, in this secured state, among the plurality of formed identification signs, the identification signs for specifying the circuit board are left, and the remaining identification signs are concealed so that they are difficult to identify. Can be used.

An abnormal state such as a floating state can be detected, and when such an abnormal state is detected, an abnormality detection signal is output. In addition, in order to enable the signal level conversion function as described above, the proximity I / F 121 is supplied with a voltage of 12 V in addition to a voltage of, for example, 5 V required for normal IC operation from the power supply device 400. ing.

  Here, all the outputs of the proximity I / F 121 (excluding the abnormality detection signal) are supplied to the second input port 122 and read into the gaming microcomputer 111 via the data bus 140, and from the main board 100 via the relay board 70. It is supplied to a test firing test apparatus (not shown). Further, the detection signals of the first start port SW51 and the second start port SW52 among the outputs of the proximity I / F 121 are input to the gaming microcomputer 111 via the inverting circuit 112 in addition to the second input port 122. It is configured. The inversion circuit 112 is provided because the signal input terminal of the gaming microcomputer 111 detects that a signal from a micro switch or the like is input, and detects negative logic, that is, low level (0 V) as an effective level. Because it is designed to do.

  In addition, detection signals from the magnetic SW 61 and the vibration SW 62 are also input to the second input port 122. The data held in the second input port 122 is read out by asserting the enable signal CE1 (changing to an effective level) by the gaming microcomputer 111 decoding the address assigned to the second input port 122. (Other ports can do the same). The enable signal of the first input port 123 is CE2.

  On the other hand, a signal from the glass frame opening SW 63 and the front frame opening SW 64 and a signal from the payout control device 200 are input to the first input port 123. These signals are supplied from the first input port 123 to the gaming microcomputer 111 via the data bus 140. The signals from the payout control device 200 include a status signal indicating a payout abnormality, a shot ball break switch signal indicating a shortage of game balls before payout, and an overflow switch signal indicating overflow. The overflow switch signal is a signal that is output when it is detected that a predetermined amount or more of the game balls are stored in the lower plate 10 (full).

  Further, the input unit 120 is provided with a Schmitt trigger circuit 124 for inputting signals such as a power failure monitoring signal, an initialization switch signal, and a reset signal from the power supply device 400 to the gaming microcomputer 111 and the like. Reference numeral 124 has a function of removing noise from these input signals. Of the signals from the power supply device 400, the power failure monitoring signal and the initialization switch signal are once inputted to the first input port 123 and taken into the gaming microcomputer 111 via the data bus 140. That is, it is treated as a signal equivalent to the signal from the above-mentioned various SWs. This is because the number of terminals receiving external signals provided in the gaming microcomputer 111 is limited.

  On the other hand, the reset signal RST from which noise has been removed by the Schmitt trigger circuit 124 is directly input to a reset terminal provided in the gaming microcomputer 111, and each port of the output unit 130 (ports 131, 132, 135, which will be described later). 136, 137). Further, the reset signal RST is directly output to the relay board 70 without going through the output unit 130, thereby turning off the test test signal held in the port (not shown) of the relay board 70 for output to the test board. It is configured as follows. Further, the reset signal RST may be configured to be output to the test firing test apparatus via the relay board 70. The reset signal RST is not supplied to the input ports 122 and 123 of the input unit 120. Data set to each port of the output unit 130 by the gaming microcomputer 111 immediately before the reset signal RST is input needs to be reset to prevent malfunction of the system, but each data of the input unit 120 is input immediately before the reset signal RST is input. This is because the data read by the gaming microcomputer 111 from the port is discarded when the gaming microcomputer 111 is reset.

Next, the output unit 130 of the game control device 100 includes the first port 131, the second port 132, the third port 135, the fourth port 136, and the fifth port 137 as output ports connected to the data bus 140. Prepare. Note that data is transmitted from the technique control device 100 to the payout control device 200 and the effect control device 300 through the ports 131 and 132 by parallel communication.
The first port 131 includes a 4-bit data signal to be output to the payout control device 200 (for example, a prize ball payout command or data), a control signal (data strobe signal) indicating validity / invalidity of the data signal, and a buffer A data strobe signal SSTB to be output to the production control device 300 via 133 is generated.
Second port 132 generates an 8-bit data signal to be output to effect control device 300.
The buffer 133 prevents the signal from being input to the game control device 100 from the side of the effect control device 300, that is, in order to secure one-way communication, the data strobe signal SSTB and the first output from the first port 131. This is a unidirectional buffer that outputs an 8-bit data signal from the 2-port 132. A similar buffer may be provided for a signal output from the first port 131 to the payout control device 200.

The third port 135 includes opening / closing data of a solenoid (large winning port solenoid) 72 for opening / closing the opening / closing member 27b of the variable winning device 27 and a solenoid (general power solenoid) 73 for opening / closing the opening / closing member 26a of the second start winning port 26. This is an output port for outputting on / off data of the digit line to which the cathode terminal of the LED of the collective display device 35 is connected.
The fourth port 136 is an output port for outputting on / off data of the segment line to which the anode terminal of the LED is connected according to the contents displayed on the collective display device 35.
The fifth port 137 is an output port for outputting information related to the pachinko machine 1 such as jackpot information to the external information terminal 71 as an external information signal. Note that the information output from the external information terminal 71 is supplied to, for example, an information collection terminal or a management device (not shown) installed in a game store.

  The output unit 130 is connected to the data bus 140 and outputs data indicating special symbol information of the variable display game to a test firing test apparatus of an accredited organization (not shown) or a signal indicating the probability of jackpot via the relay board 70. The buffer 134 is configured to be mountable. This buffer 134 is a component that is not mounted on the game control device 100 (main board) of the pachinko machine 1 as an actual machine (mass production product) installed in the game store. In addition, the detection signal of the switch which does not need to be processed such as the start port SW output from the proximity I / F 121 is supplied to the trial test apparatus via the relay board 70 without passing through the buffer 134.

  On the other hand, detection signals that cannot be supplied to the test fire testing device as they are, such as the magnetic SW 61 and the vibration SW 62, are once taken into the gaming microcomputer 111 and processed into other signals or information, for example, in a state where the gaming machine cannot control the game. An error signal indicating the presence of the error is supplied from the data bus 140 to the trial test apparatus via the buffer 134 and the relay board 70. The relay board 70 is provided with a port that takes in the signal output from the buffer 134 and supplies it to the test test apparatus, a connector that relays and transmits a signal line of a switch detection signal that does not pass through the buffer, and the like. ing. A chip enable signal CE output from the gaming microcomputer 111 is also supplied to the port on the relay board 70, and the signal of the port selected and controlled by the signal CE is supplied to the test firing test apparatus.

  The output unit 130 is provided with a plurality of drive circuits (first driver 138a to fourth driver 138d). The first driver 138a receives the opening / closing data signals of the special prize opening solenoid 72 and the general power solenoid 73 output from the third port 135, and generates and outputs respective solenoid drive signals. The second driver 138 b outputs an on / off drive signal for the digit line on the current drawing side of the collective display device 35 output from the third port 135. The third driver 138 c outputs an on / off drive signal for the segment line on the current supply side of the collective display device 35 output from the fourth port 136. The fourth driver 138d outputs an external information signal supplied from the fifth port 137 to an external device such as a management device to the external information terminal 71.

  The first driver 138a is supplied with DC32V from the power supply device 400 as a power supply voltage so that the solenoids 72 and 73 operating at 32V can be driven. Further, DC 12V is supplied to the third driver 138c for driving the segment line. Further, since the second driver 138b for driving the digit line is for pulling out the digit line corresponding to the display data with a current, the power supply voltage may be either 12V or 5V. Note that the collective display device 35 is configured such that a current flows into the anode terminal of the predetermined LED through the segment line by the third driver 138c that outputs 12V, and the cathode terminal of the predetermined LED by the second driver 138b that outputs the ground potential. As a result, current is drawn through the segment line, so that the power supply voltage flows to the LEDs sequentially selected by the dynamic drive method, and the predetermined LED is turned on. The fourth driver 138d is supplied with DC 12V in order to give the external information signal a level of 12V.

Further, the output unit 130 is provided with a photocoupler 139 for transmitting information such as an identification code and a program of each gaming machine to the external inspection device 450. The photocoupler 139 is configured to be capable of two-way communication so that the gaming microcomputer 111 can transmit and receive data to and from the inspection device 450 through serial communication. Note that such data transmission / reception is performed using a serial communication terminal of the gaming microcomputer 111 as in the case of a general general-purpose microprocessor, and therefore, ports such as the input ports 122 and 123 are not provided.
In the case of this example, a later-described main board 535 constituting the game control device 100 corresponds to the circuit board of the present invention, and a plurality of identification marks are formed on this main board (details will be described later).

(Production control device related)
Next, the configuration of the effect control device 300 and the equipment connected to the effect control device 300 will be described with reference to FIG. The effect control device 300 includes a main control microcomputer (1st CPU) 311 formed of an amusement chip (IC), as with the game microcomputer 111, and a video control microcomputer (2nd CPU) 312 that performs video control exclusively under the control of the 1st CPU 311. , VDP (Video Display Processor) 313 as a graphic processor that performs image processing for video display on the display device 41 in accordance with commands and data from the 2nd CPU 312 and various melody and sound effects are reproduced from the speakers 12a and 12b.

The contents of the output video of the display device 41 are instructed to 312, the reproduction sound is instructed to the sound source LSI 314, and the above-described drive control of the decoration devices 42 and 43 and the rendering devices 44 and 45 are executed.

For example, when a variation display game is executed, a command (for example, a variation pattern command to be described later) including stop combination (result mode) data and reach system (or variation time) data from the game control device 100. Is transmitted to the production control device 300, and the main control microcomputer 311 that receives this selects the stop mode and the change mode satisfying the change time, and the video control microcomputer 312 and the VDP 313. The display device 41 is variably displayed on the display device 41, and a special symbol variation display game is controlled in which a specific symbol combination (result mode) is finally derived and displayed.
It should be noted that aspects such as special display variation display actually implemented by the control of the effect control device 300 may be uniquely determined by a command from the game control device 100, but the conditions given by the above command A configuration in which the main control microcomputer 311 or the video control microcomputer 312 of the presentation control device 300 finally selects the mode by random number extraction or the like (a certain amount of discretion is given to select the mode also in the production control device 300). Configuration).

Here, RAMs that provide work areas for the main control microcomputer 311 and the video control microcomputer 312 are provided in the respective chips. The RAM that provides the work area may be provided outside the chip.
Although not particularly limited, data is transmitted and received in a serial manner between the main control microcomputer 311 and the video control microcomputer 312 and between the main control microcomputer 311 and the sound source LSI 314. Data is transmitted and received between the video control microcomputer 312 and the VDP 313 in a parallel manner. In general, commands and data can be transmitted in a shorter time than in the case of serial transmission by transmitting and receiving data in parallel.

Further, the video control microcomputer 312 receives from the main control microcomputer 311 a synchronization signal SYNC that informs that the video control microcomputer 312 is operating normally and gives command transmission timing. A call signal CTS and a response signal RTS are exchanged between the main control microcomputer 311 and the tone generator LSI 314 in order to transmit and receive commands and data in the handshake method.

  The video control microcomputer 312 uses a CPU that is faster, that is, more expensive than the main control microcomputer 311. By providing the video control microcomputer 312 separately from the main control microcomputer 311 and sharing the processing, it is possible to display on the display device 41 a fast-moving video with a large screen that is difficult to achieve with the main control microcomputer 311 alone. In addition, an increase in cost can be suppressed as compared with the case where two CPUs having processing capabilities equivalent to those of the video control microcomputer 312 are used. Also, by providing two CPUs, it becomes possible to separately develop the control programs for the two CPUs in parallel, thereby shortening the development period of the new model.

  In addition, the effect control device 300 has an interface chip (command I / F) that receives a command (8-bit data signal output from the second port 132) transmitted from the game microcomputer 111 of the game control device 100. 331 is provided. Via this command I / F 331, control commands from the gaming microcomputer 111, such as decoration special figure holding number command, special figure type / design information command, variation pattern random number command, customer waiting demonstration command, variation pattern command, and The main control microcomputer 311 receives a fanfare command or the like. Since the game microcomputer 111 of the game control device 100 operates at DC 5V and the main control microcomputer 311 of the effect control device 300 operates at DC 3.3V, the command I / F 331 is provided with a signal level conversion function. Yes.

  The effect control device 300 includes a panel decoration LED control circuit 332 for driving and controlling the LEDs of the panel decoration device 42, a frame decoration LED control circuit 333 for driving and controlling the LEDs of the frame decoration device 43, and the panel.

Is provided. These control circuits 332 to 335 are connected to a main control microcomputer (1st CPU) 311 via an address / data bus 340. Note that a light source other than the LED may be used as the light source of the panel decoration device 42 or the frame decoration device 43.

  Furthermore, in the effect control device 300, the effect button SW46 built in the effect button 9 provided on the glass frame 5 and the on / off state of the effect motor SW47 for detecting the initial position of the motor in the panel effect device 44 are displayed. SW input circuit 336 for detecting the signal and inputting a detection signal to main control microcomputer (1st CPU) 311; amplifier circuit 337a including an audio power amplifier for driving upper speaker 12a provided on glass frame 5; An amplifier circuit 337b for driving the provided lower speaker 12b is provided.

In addition to DC12V for driving the display device 41 composed of a liquid crystal panel, DC5V serving as the power supply voltage for the command I / F 331, DC18V for driving the LED and the speakers 12a and 12b, and direct current voltages thereof. It is configured to generate a voltage of NDC 24V that is used as a reference for the above and used to turn on the power supply monitor lamp. Further, when an LSI that operates at a low voltage such as 3.3 V or 1.2 V is used as the main control microcomputer (1st CPU) 311 or the video control microcomputer (2nd CPU) 312, DC 3. The effect control device 300 is provided with a DC-DC converter for generating 3V or DC 1.2V. The DC-DC converter may be provided in the normal power supply unit 410.

  The reset signal RST generated by the control signal generation unit 430 of the power supply apparatus 400 is supplied to the main control microcomputer 311, the video control microcomputer 312, the VDP 313, the tone generator LSI 314, the control circuits 332 to 335, and the amplifier circuits 337 a and 337 b described above. These are reset. In this embodiment, a general-purpose port of the video control microcomputer 312 is used to generate and supply a reset signal to the VDP 313. Thereby, the cooperation of the operations of the video control microcomputer 312 and the VDP 313 can be improved.

  In the case of this example, the circuit board constituting the effect control device 300 corresponds to the sub control board. As described above, the effect control device 300 (sub control board) that controls the display device 41 controls the speaker, the lamps, the movable part for decoration, and the like, which will be described later, constituting the game control device 100. The main board 535 indirectly controls the movable part and the like by sending a control command to the sub-control board. Therefore, the hardware configuration such as the wiring pattern of the main board 535 is basically the same regardless of the model, and technically the main board 535 is installed by installing a game program for each model in the gaming machine microcomputer 111. Can be shared with different models and brands.

E. Outline of Game Next, an outline of a game performed in the pachinko machine of this example and a flow of the game will be described.
First, at the beginning of the game (or before the start of the game), the customer is in a waiting state (during demonstration), and a command for instructing display of the customer waiting screen is transmitted from the game control device 100 to the effect control device 300. Then, a customer waiting screen (moving image or still image) is displayed on the display unit 41a of the display device 41. At the beginning of the game, generally, the game state is in the normal mode (normal game state). In this normal mode, the probability that the special figure is a big hit is a normal probability (a lower probability than the probability variation mode described later).

  When the game ball that has been driven into the game area 22 through the guide rail 21 wins the special winning start winning opening 25 or 26 (that is, when there is a special winning start winning), the fluctuation display of the special figure Is sent from the game control device 100 to the effect control device 300, and a display (so-called variable display) in which a special figure (including numbers, characters, symbols, patterns, etc.) fluctuates (for example, scrolls) on the display unit 41a. ) Is performed, and a special figure variation display game (hereinafter referred to as a special figure variation display game) is performed.

And, if the stop result of this special figure change display game (a combination of special figures derived by the change display) is a special result (for example, “3, 3, 3”, etc.), a privilege called a big hit is given. It is given to the player. In terms of control, for example, a value such as a big hit random number is extracted and stored on the condition that there has been a start prize, and this extracted and stored random number value is compared with a predetermined determination value at the time of determination. Based on the comparison determination result, whether or not to make a big hit is determined in advance, and in response to this determination, the special figure variation display game is started.
In addition, in the normal mode, if the stop result of the special figure variation display game is a specific aspect of the special result (for example, “7, 7, 7”), it will be the big hit and after the big hit game The game state shifts from the normal mode to the probability change mode (after a special prize period to be described later). In this probability variation mode, control is performed to increase the probability that the special figure will be a big hit (hereinafter referred to as the special figure big hit probability).

  In the second half of this variable display game, a reach state may occur. The reach state is a display state at the time when the variable display control has advanced to the stage before the entire display result is derived and displayed in the variable display game, and before the entire display result is derived and displayed. This means a display state in a case where at least a part of the display results of the plurality of determined variable display areas satisfies a condition for a special result. A typical reach state is a display state that satisfies a condition that a display result that has already been derived and displayed is a special result when some of the plurality of display results have not yet been derived and displayed (for example, “3, If a special result is obtained when three rows of special charts such as “3, 3” are obtained, only the central one row changes such as “3, ↓, 3” and the left and right two rows are derived as “3”. State). In addition, for example, a state (so-called full rotation reach) in which a variable display is performed by a plurality of variable display areas while maintaining a state in which special results are aligned is also included in the reach state.

In addition, when a big hit is made in a specific manner (a slot of “7, 7, 7”) in the probability change mode, the game state is also maintained in the probability change mode. However, the game state shifts to the normal mode when the number of fluctuations of the special figure reaches a predetermined number without generating a big hit after entering the probability variation mode. That is, in the probability variation mode, the number of fluctuations of the special figure is limited to a predetermined number. Here, the predetermined number of times is not particularly limited, is a predetermined number of times, and may be different for each type of jackpot.
Moreover, depending on the stop result of the variable display game, a mode in which a so-called time reduction state (time reduction mode) occurs may be used. The short time state is a state in which the fluctuation time of the special figure or ordinary figure variable display game is controlled to be shorter than the normal state, and as a result, the special figure or ordinary figure is easily hit.

  When the jackpot is reached and the jackpot state is reached, a fanfare period (a period in which an output of a sound effect that produces a jackpot is executed, etc.) is passed through a specified time ( For example, within a range not exceeding 30 seconds), for example, an opening operation (a jackpot round) that is temporarily opened for a period of up to 10 winnings is performed. This opening operation is repeated for a specified number of lands. Further, in this jackpot state, a command for instructing display of a jackpot screen for producing the jackpot state or notifying the player of the number of jackpot rounds is transmitted from the game control device 100 to the effect control device 300, and the display unit 41a. Then, such a big hit display is executed.

The period in which the jackpot is in effect (the fanfare period, the period of the jackpot round in which the jackpot 12a is opened, and the interval period between the jackpot round and the next jackpot round) corresponds to the special prize period. .
In addition, as the number of rounds of the big hit, for example, a big hit of 15 rounds is usually the main big hit, but a configuration of generating a 16R big hit as a premier or other configurations may be used. Further, there may be a two-round big hit or the like as a so-called abruptness (a sudden probability change in which the big hit probability changes via a big hit with few balls).

In addition, when a game ball is further won in the start winning opening 25 or 26 during the special figure fluctuation display game or in the big hit, a special figure start memory hold display is performed on the display unit 41a or the like, for example, up to four. After the variation display game or the big hit state is stored, the variation display game of the above special figure is repeated or returned to the customer waiting state based on the start memory.
That is, if the variable display game ends with a big hit, the game shifts to a big hit state, and if the variable display game ends with a start and there is a start memory, the variable display game is executed again, and the variable display game ends with a start and no start memory is stored. If the big hit ends and there is a start memory, the variable display game is executed again. If the big hit ends and there is no start memory, the flow returns to the customer wait state.

  In the case of this example, two types of fluctuations are displayed as a special figure fluctuation display game by displaying two types of special figure start memory (special figure start memory) display (special figure 1 hold display and special figure 2 hold display). A display game (a first variation display game and a second variation display game) is executed. That is, when a special figure start prize (first start prize) due to the game ball entering the first start prize opening 25 occurs, the display device 41 plays the first variation display game by the variation display of the special figure 1. When a game ball wins the first start winning opening 25 during any special figure variation display game or the like, one first start memory (start memory corresponding to the special figure 1 hold display) is stored. On the other hand, the first variation display game by the variation display of the special figure 1 is performed on the display device 41 after the special figure fluctuation display game is finished.

  Further, if there is a special figure start prize (second start prize) due to the game ball entering the second start prize opening 26, the display device 41 plays the second variation display game by the variation display of the special figure 2. When a game ball wins the second start winning opening 26 during any special figure variation display game or the like, one second start memory (start memory corresponding to the special figure 2 hold display) is stored. On the other hand, the second variation display game by the variation display of the special figure 2 is performed on the display device 41 after the above special figure fluctuation display game ends. When both the first start memory and the second start memory are present, either the first variation display game or the second variation display game is executed first in accordance with a preset rule. For example, a mode in which the second variable display game corresponding to the second start winning opening 26 is preferentially performed (that is, a mode in which the second start memory is preferentially consumed) or two types of variable display games are alternately displayed. There may be a mode to be performed.

On the other hand, when the game ball passes through the usual figure start gate during the game, a usual figure change display game (hereinafter referred to as a usual figure change display game) is displayed on the display unit 41a or the like. And if this normal map change display game result (stopped general chart) is a predetermined mode (specific display mode), a privilege called per map is granted.
At this time, a game is held in which the pair of opening / closing members 26a of the second start winning opening 26 is temporarily held in an open state where the pair of opening / closing members 26a is opened in a reverse C-shape. This makes it easier for the game ball to start and win, and accordingly, the number of executions of the special figure variation display game increases and the possibility of a big hit increases.
In addition, during the above-described normal map change display game, when a game ball is further won at the general map start gate, the general display start memory is held on the display unit 41a and the like, and up to four are stored in this case. After the end of the variable display game, the usual variable display game is repeated based on the memory.

F. Structure of Game Control Device Next, the structure of the game control device 100 will be described with reference to FIGS. 3 and 7 to 14.
The game control device 100 is a thin box-shaped unit extending along the left-right direction of the game board 20 as shown in FIG. 7 and 8, the game control device 100 includes a substrate box 534 made of resin (for example, made of a colorless and transparent resin) that has translucency and can be seen through, and the inside of the substrate box 534.

  On the other hand, in order to remove (separate) the lid member 542 from the base member 541, the disengagement direction (FIG. 7A) of the lid member 542 toward one side of the base member 541 (rightward in FIG. 7B). ) In the direction indicated by the arrow C), the engaging piece 551 faces the fitting / removing portion 552, and in this state, the cover member 542 is moved away from the substrate box 534 in the separating direction (shown by the arrow D in FIG. 8). Direction) and away from the base member 541. Accordingly, the lid member 542 moves in the overlapping direction A of the substrate box 534 and then slides in the engaging direction B to be engaged with the base member 541. On the other hand, if the base member 541 slides from the engaged state to the disengagement direction C and then moves in the separation direction D, the base member 541 is separated.

  The sealing mechanism 545 includes a plurality of sealing heads 554 (see FIG. 9) arranged on each of the left and right sides of the lid member 542 (see FIG. 9), and left and right sides of the base member 541. It comprises a plurality of sealing receiving portions 555 (see FIG. 12) arranged at positions that can overlap with the sealing head portion 554, and a sealing member (not shown) such as a one-way screw.

  The sticking part 546 includes a base sticking part 557 and a lower sticking part 558 (shown in FIG. 12) formed on the base member 541, and a lid sticking part 559 (see FIG. 9) formed on the lid member 542. The electronic tag seal can be stuck across a part of the base member 541 and a part of the lid member 542. Further, the base-side adhesive portion 557 and the lid-side adhesive portion 559 are moved in a moving direction (overlapping direction A, engagement direction B, and engagement release direction C) for attaching and separating the base member 541 and the lid member 542. , And can be assembled along the separation direction D).

  Specifically, a base-side sticking portion 557 is provided at the tip (projecting end) of the protruding portion 548 (shown in FIG. 12A) of the base member 541, and the lower-side sticking portion 558 is provided on the lower surface portion of the protruding portion 548. Is provided so as to extend in the front-rear direction of the substrate box 534.

When the base member 541 and the lid member 542 are attached to each other, the lower portion is bent toward the front side of the substrate box 534 by the lid-side adhesive portion 559, the base-side adhesive portion 557, and the lower-side adhesive portion 558. It is set as the structure in which the sticking part 546 of the state which was made is formed. In addition, in a state where the base member 541 and the lid member 542 are attached to each other, the lid side adhesive portion 559 and the base side adhesive portion 557 are joined and located on substantially the same plane.

  The board box 534 includes a locking mechanism 565 (shown in FIGS. 9 and 12) that locks the base member 541 and the lid member 542 at a location where the lid-side adhesive portion 559 and the base-side adhesive portion 557 are joined. ). More specifically, as shown in FIG. 9B, locking projections 561 are provided at both the left and right positions on the lower end surface of the lid-side adhering portion 559 of the lid member 542 so as to protrude downward. ing. In addition, this latching protrusion 561 is provided in the position which shifted | deviated to the front side (the other side in FIG.9 (b)) rather than the surface of the cover side adhesion part 559 in the front-back direction. On the other hand, as shown in FIG. 12A, the base member 541 and the lid member 542 are attached to the left and right side positions of the base-side sticking portion 557 in the protruding portion 548 of the base member 541 (described above). In a state where the engagement mechanism 544 is engaged), an overlapping portion 566 that overlaps with the locking protrusion 561 is formed. Further, an engagement / disengagement portion 567 is formed at a position shifted from the overlapping portion 566 in the disengagement direction C. The engagement protrusion 561 is a notch that can be engaged / removed in the front-rear direction.

  The locking mechanism 565 is configured to function as follows. That is, when the base member 541 and the lid member 542 are attached to each other, when the lid member 542 is moved in the overlapping direction A, the locking projection 561 is fitted into the fitting / removing portion 567. Also move to the back (front side). After that, when the lid member 542 is slid in the engagement direction B, the locking projection 561 is superimposed on the front side of the overlapping portion 566 (the other side in FIG. The attaching portion 559 engages with the base side attaching portion 557 in a state where mutual movement in the front-rear direction is restricted. When the base member 541 and the lid member 542 are attached to each other and the locking mechanism 565 is actuated in this way, the overlapped locking protrusion 561 and overlapping portion 566 are not shown in the drawing such as screws. It is set as the structure which can mutually adhere by a fastening member.

Next, the electronic tag seal will be described.
Although not shown, the electronic tag seal is configured to include a rectangular base sheet and a long tag portion attached to the rear surface side of the base sheet. In addition, the tag unit includes a chip unit (IC chip) that stores unique identification information (for example, identification ID) related to the game control device 100, and an antenna unit that can transmit the identification information. The identified identification information is read by an external reading device (not shown), and it is possible to confirm whether or not the game control device 100 is a genuine product. In addition, a long antenna portion is linearly disposed along a diagonal line on the rear surface side of the rectangular base sheet, a chip portion is disposed at a predetermined position of the antenna portion, and an electronic tag seal is attached to the attachment portion 546. Then, for example, the chip part is set on the base side adhesive part 557, and the antenna part is set so as to intersect the boundary (fitting boundary) between the base side adhesive part 557 and the lid side adhesive part 559. Yes.

  And the character of "no opening" is printed on the surface of the electronic tag seal (the surface of the base sheet), in other words, the surface located on the back side of the game board 20 in a state of being attached to the attaching portion 546, and the tag portion ( An adhesive layer is provided on the entire back surface of the electronic tag seal including the chip portion and the antenna portion, in other words, the entire surface facing the adhesive portion 546, and the electronic tag seal can be attached to the adhesive portion 546 via the adhesive layer. It is said. In addition, although it is desirable to arrange | position the antenna part in a straight line on the diagonal of a base sheet, you may arrange | position in the state parallel to the diagonal of a base sheet, or the state inclined somewhat.

Next, the protective cover 537 will be described.
As shown in FIG. 14, the protective cover 537 is an L-shaped member that can be attached to the sticking portion 546 to cover the electronic tag seal. At the upper end of the protective cover 537, a fastening portion 568 is formed so as to protrude upward, and a through hole 568a penetrating in the front-rear direction is formed in the fastening portion 568. On the other hand, on the upper side of the lid side adhering portion 559 of the lid member 542, as shown in FIG. 9A and the like, a fitting recess 569 into which the fastening portion 568 is fitted is formed. A screw hole 569a is formed in the rear surface toward the front.

In FIG. 10A and the like, reference numeral 569b indicates a boss portion formed on the front surface side (inner surface side) of the lid member 542, and the screw hole 569a is formed inside the boss portion. .
Further, when the protective cover 537 is attached to the sticking portion 546, the fastening portion 568 is configured to fit into the fitting recess 569. In this mounted state, the protective cover 537 is fixed to the lid member 542 by a fastening member (not shown) such as a screw that is inserted from the through hole 568a of the fastening portion 568 and screwed into the screw hole 569a. It becomes the composition which is done.

  In order to assemble the game control apparatus 100 having such a configuration, first, the main board 535 is fixed to the inside of the lid member 542 and the wiring connector 535b is faced to the connector opening 547. In this state, the lid member 542 is The posture is set so that the main substrate 535 and the inside of the base member 541 face each other. When the posture of the lid member 542 is set, the lid member 542 is moved along the overlapping direction A (shown in FIG. 8) to overlap the base member 541 and the engaging piece 551 is passed through the fitting / removing portion 552. . Further, the locking protrusion 561 is fitted into the fitting / removing part 567 and is located behind the fitting / removing part 567. Then, as shown in FIG. 7A, the lid member 542 is slid in the engagement direction B to engage the engagement piece 551 with the engagement groove portion 550 to bring the engagement mechanism 544 into the engaged state. The aforementioned locking mechanism 565 is also in the locked state. Accordingly, the base member 541 and the lid member 542 are attached to each other with the main board 535 mounted on the inside.

  If the base member 541 and the lid member 542 are attached to each other, the sealing head portion 554 and the sealing receiving portion 555 are fastened with the sealing member and the substrate box 534 is attached before attaching the electronic tag seal. Seal. Further, the electronic tag seal is attached in a state where the edge of the electronic tag seal is along the edge of the attaching portion 546. Then, the RFID tag seal is bent at the lower part of the RFID tag seal and adhered onto the lower adhesive portion 558, and the locking mechanism 565 is covered with a base sheet, and the chip portion is disposed on the base adhesive portion 557, for example. Is done. Also, in FIG. 9B, for example, the antenna unit is set in a posture inclined upward toward the left side, the extending direction of the antenna unit intersects the engagement direction B and the disengagement direction C, The antenna portion is crossed at the fitting boundary between the base side adhesive portion 557 and the lid side adhesive portion 559. When the electronic tag seal is attached to the attaching portion 546, the protective cover 537 is attached to the attaching portion 546 to cover the electronic tag seal. By attaching the protective cover 537, it is possible to prevent inconvenience that the electronic tag seal is inadvertently damaged and the identification information cannot be transmitted.

  In the game control apparatus 100 assembled in this way, if the board box 534 is tampered with without removing the electronic tag seal, the following occurs. That is, the sealing head portion 554 and the sealing receiving portion 555 fixed (sealed) with the sealing member are cut out from the substrate box 534. In addition, the protective cover 537 is removed, and the overlapping portion 566 and the locking projection 561 are fixed by cutting off the portion covering the overlapping portion 566 of the electronic tag seal attached to the attaching portion 546. The member is exposed and the exposed fastening member is removed. Thus, in order to separate the base member 541 and the lid member 542, a part of the electronic tag seal is broken and the fastening member is removed. Therefore, if the electronic tag seal is visually checked to see if it has been broken, an unauthorized person has separated the base member 541 and the lid member 542 or attempted to separate the base member 541 and the lid member 542. You can easily grasp this.

  Then, when the lid member 542 is slid in the disengagement direction C in a state where the fastening member and the sealing mechanism 545 that have fixed the overlapping portion 566 and the locking projection 561 are removed, the game control device 100 displays the electronic tag seal. Among them, the part pasted on the base side sticking part 557 including the chip part is left on the base side sticking part 557, the electronic tag seal is broken along the fitting boundary, and further the antenna part is cut. . In addition, the electronic tag seal is cut in a state where the lower part of the electronic tag seal is left in the lower adhesive portion 558. Therefore, it is possible to invalidate the transmission function of the electronic tag seal (specifically, the function of transmitting identification information). Further, based on the fact that the identification information is not transmitted, it is possible to grasp that the board box 534 has been opened illegally. And the inconvenience that the transmission function of the electronic tag seal is reused after an illegal act is performed can be prevented.

  In the above embodiment, the movement direction for attaching / separating the base member 541 and the lid member 542 is the direction along the front / back direction of the substrate box 534 (overlapping direction A, separation direction D) and the substrate box 534. However, the present invention is not limited to this. For example, the base member 541 and the lid member 542 may be attached / separated only by moving the lid member 542 only in the direction along the front and back direction of the substrate box 534, or the lid member 542 may be attached to the substrate box 534. The base member 541 and the lid member 542 may be attached / separated only by moving in the direction along the left-right direction.

G. Next, the structure of the main substrate 535 and the identification mark will be described with reference to FIGS. 11 and 15 to 16.
(A) Structure of main substrate First, the structure of the main substrate 535 will be described. As shown in FIG. 15C, the main substrate 535 has a conductive layer 572 made of a conductive material (for example, copper) formed on the surface of a base substrate 571 that is an insulating and plate-like base material. A substrate body 574 is formed by forming a resist layer 573 as an insulating protective film on the surface of the conductive layer 572. Here, before the conductive layer 572 is covered with the resist layer 573, the conductive layer 572 is patterned by a known pattern forming technique (for example, etching or the like) to form a conductive pattern (also referred to as a wiring pattern) as a circuit conductor (circuit wiring). Is forming. That is, the board main body 574 is, for example, a printed wiring board (bare board), and the main board 535 is, for example, a printed circuit board (which is obtained by mounting components on a printed wiring board). In addition, there is a term “printed circuit board”, but this is not used here because it may mean a printed wiring board on which no component is mounted or a printed circuit board on which a component is mounted. .

  Further, as shown in FIGS. 11A and 11B, the substrate body 574 has a rectangular shape as a whole. Various electronic components including a chip of the gaming microcomputer 111 and a plurality of wiring connectors 535b are mounted on the board body 574, and the main board 535 shown in FIGS. 11A and 11B (that is, game control). The circuit board on which the circuit of the apparatus 100 is formed is configured.

(B) Main board identification mark Next, the main board 535 identification mark will be described. In this example, the main board 535 has a plurality of (two in this case) identification marks as shown in FIG. 15A at the position of the upper left edge indicated by reference numeral H1 in FIGS. 581 and 582 are formed. The identification marks 581 and 582 are board identification information (information consisting of letters, numbers, symbols, figures, etc.) that can specify the model of the gaming machine on which the circuit board (in this case, the main board 535) is used, and the manufacturer or brand. ) Is displayed.

  In this case, as shown in FIG. 15A, the identification mark 581 includes board specifying information made up of the characters “Sophia” (may be “SOPHIA”) as the manufacturer name or brand name, and the model management number. The board specifying information consisting of the letters and numbers “SP09015” as shown in FIG. 5 is represented by a display with a conductive pattern not related to the conductive state in a state where it is arranged in a line on the left and right. Further, as shown in FIG. 15A, the identification mark 582 includes board specifying information consisting of characters “NISHIJIN” (may be “Nishijin”) as a manufacturer name or brand name, and a model management number. The board specifying information consisting of letters and numbers “NS08015” is displayed in a state of being displayed in a conductive pattern that is not related to a conductive state in a state where it is arranged in a line on the left and right.

As described above, the identification marks 581 and 582 of the present example display the substrate specifying information by displaying with the conductive pattern not related to the conductive state formed by patterning the conductive layer 572.
Here, “display with a conductive pattern not related to the conductive state” means that the conductive pattern includes, for example, the letters “Sophia” itself, and the outside (background) of the letters “Sofia” is the base after removing the conductive layer 572. This is a display with a configuration in which information such as characters can be recognized by showing the substrate surface (the surface of the base substrate 571) to an observer. In FIG. 15A, the letters and numbers representing the above-mentioned manufacturing company names and model management numbers of the identification marks 581 and 582 are surrounded by a rectangular line. The boundary between the portion with and without the conductive layer 572 is shown. In addition, the boundary illustrated by the surrounding line is not limited to a rectangular shape as illustrated, and the shape and size thereof are not limited.

Here, the “conductive pattern not related to the conductive state” is not a conductive pattern as a circuit conductor constituting a circuit (in this case, a circuit constituting the game control device 100), but from a conductive layer 572 irrelevant to the circuit. Means a pattern. However, a conductive pattern as a circuit conductor having a ground potential may be included. The conductive pattern not related to the conductive state (that is, the conductive pattern constituting the identification marks 581 and 582) is formed at the same time as the conductive pattern as the circuit conductor of the circuit constituting the game control device 100 is formed, for example. Then, the manufacturing process of the circuit board (in this case, the main board 535) does not increase.
In addition, when the identification mark is configured by the conductive layer 572 as described above, it becomes difficult to remove or rewrite the identification mark itself. In particular, it is very difficult to remove or rewrite without leaving a trace.

  In the present embodiment, among the plurality of identification marks 581 and 582 formed as described above, except for the identification mark for specifying the circuit board (in this case, the main board 535), concealment is difficult. The circuit board can be specified by an identification mark that is not concealed. That is, at least in the state of being finally assembled and used in a gaming machine, the remaining identification signs other than the identification signs corresponding to the model of the gaming machine in which the circuit board is used are concealed so as to be difficult to identify. It has become.

  Here, as a concealing means, for example, as shown in FIGS. 15B and 15C, concealing layers 575 and 576 that do not transmit light are formed on the surface of the resist layer 573 so as to cover the identification mark. The concealing layers 575 and 576 may be, for example, a coating film formed by applying a paint, or a plate-like member (plastic or paper) attached to the surface of the resist layer 573 with an adhesive or an adhesive. There may be. For example, it may be formed by a method (usually silk printing) similar to the method of forming the display of the part number of each component mounted on the circuit board on the circuit board. In this case, by forming the part number display and the concealing layers 575 and 576 at the same time, an increase in the number of work steps can be avoided. In addition, when the concealing layer is constituted by a plate-like member attached to the surface of the resist layer with an adhesive or a pressure-sensitive adhesive, adhesion that always leaves a trace when it is simply peeled off (or peeled off) by human power or the like. It is preferably an agent or a pressure-sensitive adhesive.

  Also, as a concealing procedure, first, in the storage state in which the circuit board is stocked before use, all the formed identification signs are concealed, and the circuit board is used for the production of a specific gaming machine. In use, there is a method in which only the corresponding identification mark is exposed by removing only the concealment of the corresponding identification mark. Secondly, in the storage state, all of the formed identification signs are not concealed, and when the circuit board is used for the production of a specific gaming machine, the remaining identification signs excluding the corresponding identification signs There is a way to hide. With any of these methods, the circuit board in the storage state can be shared.

  As an aspect for removing the concealment (an aspect for removing the concealment), the concealment layer may be physically peeled off or scraped off by human power, a tool, or a machine tool (for example, a milling machine or an ultrasonic spindle device). A mode of removing (for example, peeling) by laser processing using laser light is desirable. In particular, laser processing is preferable in order to cleanly remove only the concealment layer while preventing damage to the circuit board and to achieve a clean finish of the portion from which the concealment layer has been removed.

  The ultrasonic spindle device is a device that rotates a tool such as a drill at a high speed while ultrasonically vibrating with a very small amplitude in the axial direction, and can be processed even with a brittle material such as glass, ceramic, or plastic. Laser processing is a processing technique in which an object is melted and evaporated by irradiating laser light, and removal, cutting, drilling, and the like are possible without contact. Since it is non-contact, it can be processed without applying extra stress to the object, and there is no damage due to deformation or cracking of the object. In addition, fine processing can be performed with a laser beam having a small beam diameter, and the processing depth can be finely adjusted by adjusting the output of the laser beam. For this reason, if laser processing is used, only the concealing layer can be removed cleanly without damaging the circuit board.

Further, as a procedure for mounting components (including electronic components and wiring connectors) on the circuit board, in the case of the main board 535 of this example, for example, the game microcomputer 111 has different software (programs) installed for each model. It cannot be mounted in the storage state, and must be mounted on a circuit board (including terminal connection such as soldering, etc.) when used for production of a specific gaming machine.
On the other hand, with respect to other parts (hereinafter referred to as common mounting parts) excluding parts unique to each model (hereinafter referred to as specific mounting parts) depending on the model (including differences in brand) such as the gaming microcomputer 111, The same is true even if the model is different, and such a common mounting component may be mounted in the storage state or may not be mounted in the storage state.

  In addition, in the first concealment procedure, a component (one or both of the common mounting component and the specific mounting component, the same applies below) is mounted before the step of removing only the concealment of the corresponding identification mark. Alternatively, components may be mounted after the same process. In the second concealment procedure, the component may be mounted before the step of concealing the identification mark excluding the corresponding identification mark, or the component may be mounted after the step. .

Hereinafter, the concealment procedure and the like will be described using a specific example shown in FIG.
First, as a first concealment procedure, in the storage state in which the main board 535 is stocked, all the identification marks 581 and 582 are concealed as shown in FIGS. 15B, 15C and 15D. The layers 575 and 576 are formed by, for example, silk printing. When the main board 535 is used for the production of the model K1 corresponding to the management number “SP09015” of “Sofia”, the specific mounting parts such as the gaming microcomputer 111 corresponding to the model K1 are mounted, and Only the concealment layer 575 of the identification mark 581 is removed as shown in FIGS. 16A and 16B, for example, by laser processing. When the main board 535 is used for the production of the model K2 corresponding to the management number “NS08015” of “NISHIJIN”, the specific mounting parts such as the gaming microcomputer 111 corresponding to the model K2 are mounted, and Only the concealment layer 576 of the identification mark 582 is removed as shown in FIGS. 16C and 16D, for example, by laser processing.

  At this time, the common mounting component may be mounted at the time of use (for example, mounted in the same process as the specific mounting component) without being mounted on the main substrate 535 in the storage state. It may be preinstalled in 535. Further, the display of the part number may be performed in a process different from the process of forming the concealment layers 575 and 576 in advance on the main substrate 535 in the storage state, but the concealment layer is previously displayed on the main substrate 535 in the storage state. If, for example, silk printing is performed at the same time as the step of forming 575,576, the number of steps does not increase.

  In the case of the first concealment procedure, in the storage state, the concealment layers 575 and 576 are formed for all of the identification marks 581 and 582, so that the main substrate 535 is either of the models K1 and K2. It becomes a state that can be commonly used for models (hereinafter, a circuit board in such a state is referred to as a common circuit board). That is, when the common mounting component is not mounted in the storage state, the concealing layer 575 is formed on the substrate body 574 having a common conductive pattern (including identification marks 581 and 582) and also coated with the resist layer 573. , 576 is a common circuit board. When a common mounting component is mounted in the storage state, a common circuit board is formed by forming concealing layers 575 and 576 on the substrate body 574 and mounting the common mounting component. In other words, it can be stocked in a state where it can be used in common at two stages before and after mounting the common mounting component.

  Next, as a second concealment procedure, the concealment layer 575 is not formed on all the identification marks 581 and 582 in the storage state in which the main substrate 535 is stocked as shown in FIG. . When the main board 535 is used for the production of the model K1 corresponding to the management number “SP09015” of “Sofia”, a specific mounting component such as the game microcomputer 111 corresponding to the model K1 is mounted and applicable. As shown in FIGS. 16A and 16B, a concealing layer 576 is formed on the remaining identification mark 582 excluding the identification mark 581. In addition, when the main board 535 is used for production of the model K2 corresponding to the management number “NS08015” of “NISHIJIN”, a specific mounting component such as the gaming microcomputer 111 corresponding to the model K2 is mounted and applicable. As shown in FIGS. 16C and 16D, a concealing layer 575 is formed on the remaining identification mark 581 excluding the identification mark 582.

  At this time, the common mounting component may be mounted at the time of use (for example, mounted in the same process as the specific mounting component) without being mounted on the main substrate 535 in the storage state. It may be preinstalled in 535. Further, the display of the part number may be formed in a process different from the process of forming the concealment layer 575 or 576 when used for production (for example, the display of the part number is formed in the state of the common circuit board). However, if it is simultaneously formed by, for example, silk printing in the same process as the process of forming the concealing layer 575 or 576 when used for production, the number of processes does not increase.

  In the case of this second concealment procedure, since the concealment layer 575 is not formed for all of the identification marks 581 and 582 in the storage state, the main substrate 535 can still be used in common for all models. State (common circuit board). That is, when the common mounting component is not mounted in the storage state, the substrate main body 574 having a common conductive pattern (including identification marks 581 and 582) and also coated with the resist layer 573 is provided as a common circuit board. It becomes. When a common mounting component is mounted in the storage state, a common circuit board is obtained by mounting the common mounting component on the board body 574. In other words, it can be stocked in a state where it can be used in common at two stages before and after mounting the common mounting component.

According to Example 1 demonstrated above, there exist the following effects.
That is, first, since the identification marks 581 and 582 are constituted by a conductive pattern formed by patterning the conductive layer 572, it is difficult to erase or rewrite itself. In particular, it is very difficult to remove or rewrite the identification marks 581 and 582 without leaving a trace. For this reason, fraudulent acts such as unauthorized diversion of the circuit board (in this case, the main board 535) can be prevented. It is to be noted that fraudulent acts that change the exposed identification sign by illegally removing the concealment layer 575 or 576 that conceals one of the identification signs 581 and 582 and illegally concealing the other identification sign. Can be considered. However, in this case, the range that can be used illegally is limited to models that correspond to any of a plurality of identification signs, and there is a possibility that fraudulent acts can be discovered by the traces from which the concealment layer has been removed or the concealment layer that has been illegally formed. high.
In addition, a circuit board (in this case, the main board 535) having a common wiring pattern (conductive pattern) can be shared and used effectively in the state of the common circuit board even if the models are different, and can be reused. Disposal due to inventory can be suppressed. In addition, since circuit boards can be mass-produced, costs can be reduced.

Further, when the concealing layer 575 or 576 is removed by laser processing in the first procedure, there is an effect that the work efficiency is good even if an electronic component (for example, a common mounting component) is mounted. This is because, for example, in the second procedure, it is difficult to form the concealment layer 575 or 576 by silk printing or the like in a state where the electronic component is mounted because the electronic component becomes an obstacle. On the other hand, since the operation of removing the masking layers 575 and 576 by laser processing is non-contact processing, the operation efficiency is good.
Also, the concealing layers 575 and 576 formed by silk printing or the like are removed in the first procedure, and the conductive pattern (resist layer 573 + conductive layer 572) coated with the resist layer 573 is not removed. Even in a state where the electronic component is mounted, there is an effect that it is not necessary to consider the risk of short-circuiting due to peeling debris or chips of the conductive layer 572 between terminals of an IC or the like which is an electronic component.

Next, a second embodiment of the present invention will be described with reference to FIGS.
The second embodiment is characterized in that the main substrate 535 includes a substrate body 574 having identification marks 583 and 584 by facing the base substrate surface, and other configurations may be the same as those of the first embodiment. That is, in this example, as shown in FIGS. 17A to 17C, the circuit board (in this case, the main board) is displayed by displaying the base board surface (the surface of the base board 571) from the conductive pattern 572. 535) can be specified, and identification marks 583 and 584 are displayed. “Display by facing the base substrate surface from the conductive pattern” means that the base substrate surface can be seen as, for example, “Sophia”, that is, the conductive pattern on the outside (background) forming the letters “Sofia” (preferably, The portion that is not related to the conduction state or the portion that becomes the ground potential on the circuit) and that forms the characters “Sophia” is a display that can recognize information such as characters by removing the conductive layer. That is, the “display by facing the base substrate surface from the conductive pattern” has a relationship in which characters and the background are reversed with respect to the “display by the conductive pattern” in the first embodiment.

The display contents of the identification marks 583 and 584 are the same as the identification marks 581 and 582 of the first embodiment.
Also in the second embodiment, like the first embodiment, the concealing layers 575 and 576 finally conceal the identification marks 583 and 584 that do not correspond to the used model (FIGS. 18A to 18D). Reference) and the same effects can be obtained.

Next, Embodiment 3 of the present invention will be described with reference to FIG.
In the third embodiment, as shown in FIG. 19A, one of the identification marks 581 and 582 is formed on the edge of the long side of the substrate body 574, and the other identification mark 582 is formed on the substrate body. It is characterized in that it is formed at the edge on the short side of 574, and the other configuration may be the same as in the first embodiment.
Also in the third embodiment, as in the first embodiment, the concealing layers 575 and 576 finally conceal the identification marks 581 and 582 that do not correspond to the used model (FIGS. 19B and 19C). Reference) and the same effects can be obtained.
Moreover, when the identification mark is formed and arranged separately in the longitudinal direction and the short direction as in the third embodiment, it can be identified by the position of the identification mark that is exposed, so any model (or which It is easy to identify the circuit board of the manufacturer or brand).

Next, a fourth embodiment of the present invention will be described with reference to FIG.
Example 4 is an example in which three identification marks 585, 586, 587 are formed. The configuration may be the same as that of the first embodiment except that there are three identification marks and corresponding shielding layers 577, 578, and 579. As shown in FIG. 20, the identification signs 585, 586, 587 are all of the same brand “Sophia” in this example, and display the difference of models within the same brand.

In Example 3, as in Example 1, the concealing layer finally conceals the one of the identification marks 585 to 587 that does not correspond to the used model (see FIGS. 20B to 20D). Similar effects can be obtained.
Thus, there may be three or more identification marks of the present invention. Further, as in the fourth embodiment, all of the plurality of identification signs may be of the same brand, or as in the first embodiment, the plurality of identification signs may have different brands.

Next, a fifth embodiment of the present invention will be described.
The fifth embodiment is an aspect in which, for example, a so-called laser marker hides an identification mark (not an identification mark that specifies a circuit board) that is not exposed among the identification marks 581 and 582. Other configurations may be the same as those in the first embodiment.

  The laser marker is a technique for changing or coloring a material using laser light, and includes a marking for thinning a color by firing, a marking by condensation, a marking by carbonization, and a marking by chemical change. Among these, for example, marking by condensation is performed by adding a predetermined additive (for example, a pigment having a high absorption rate of laser light) to the material and condensing by increasing the molecular density of the additive due to the thermal effect of the irradiated laser light. For example, a part of the surface of the material is changed to a dark color. Carbonization marking also adds an additive to the material and continues to irradiate the laser beam with higher energy to carbonize the polymer around the additive, for example, the surface of the material. The part is colored black. In addition, marking by chemical change causes changes in the crystal structure of the ions and the amount of hydration in the crystals by irradiating laser light when the components such as pigments in the substrate contain metal ions. Thus, the composition itself of the component is chemically changed to increase the concentration of the pigment or the like to develop a color.

In the fifth embodiment, for example, using any one of the marking by condensation, the marking by carbonization, and the marking by chemical change, for example, the identification marks 581 and 582 on the substrate body 574 in the state shown in FIG. The conductive pattern (conductive layer 572) itself that constitutes an identification mark that is not to be exposed, and the resist layer 573 and / or the base substrate 571 located on or around the surface of the conductive pattern that constitutes this identification mark are changed or colored. Thus, the identification mark that is not exposed is concealed with difficulty in identification.
The present invention may employ a concealment method by such discoloration or color development. In this case, it is not necessary to form a layer that does not transmit light, such as the concealment layers 575 and 576 described above. In this case, there is also an advantage that peeling dust and shavings are not generated.

The fifth embodiment may have the following aspect. That is, for example, a marking that is made of a material that can be changed or colored by the above-mentioned marking by condensation, marking by carbonization, or marking by chemical change, and marking for marking by a material that is transparent or translucent at first (before marking) A layer is formed. The marking layer is formed in a position range that covers at least the identification marks 581 and 582, similarly to the concealment layers 575 and 576. Then, when concealing an identification mark that is not exposed, the marking layer is concealed by discoloring or coloring at least a portion of the marking layer located on the surface of the identification mark to make the identification mark difficult to see. The method may be used.
In this embodiment, the portion to be marked (marking layer) can be easily composed of an optimum material for marking (added with an additive if necessary). There is an effect that can be concealed.

Next, the inventive concept extracted from each of the above embodiments will be described sequentially.
<Invention concept A2>
First, an invention concept A2 corresponding to a subordinate concept invention of the invention described in claim 1 of the present application (invention concept A1)

As a result, a circuit board having a common wiring pattern can be used effectively, can be reused, and can be prevented from being discarded due to inventory. Moreover, since mass production becomes possible, cost can be suppressed.
In addition, for example, silk printed matter is removed, and the circuit pattern (for example, resist + copper foil) coated with resist is not removed. Therefore, even when electronic parts are mounted, the circuit pattern between IC terminals is not removed. There is an effect that it is not necessary to consider the danger of short-circuiting due to circuit pattern removal waste (for example, peeling waste).

As a result, a circuit board having a common wiring pattern can be used effectively, can be reused, and can be prevented from being discarded due to inventory. Moreover, since mass production becomes possible, cost can be suppressed.

In addition, since removal (for example, peeling) is performed with a laser, there is an effect that even if an electronic component is mounted, the working efficiency is improved as compared with concealing by silk printing or the like in that state.
In addition, for example, silk printed matter is removed, and the circuit pattern (for example, resist + copper foil) coated with resist is not removed. Therefore, even when electronic parts are mounted, the circuit pattern between IC terminals is not removed.

Next, another embodiment B (Examples B1 to B4) for solving the same problem as the present invention, which is an embodiment different from each of the above-described Examples 1 to 5 (Embodiment A), will be described sequentially. To do.
<Example B1>
In the embodiment B1, among the identification marks formed on the main board (the circuit board of the game control device), the remaining identification signs except for the identification mark for specifying the main board are removed with difficulty in removal. The main substrate can be specified by the identification mark that is not. The configuration other than the identification mark may be the same as that of the first embodiment.

  That is, in this example, a plurality of main boards 535 are provided at the position of the upper left edge indicated by reference numeral H1 in FIGS. 11A and 11B (in this case, as shown in FIGS. 21A and 21C). Two identification marks 581 and 582 are formed, and these identification marks 581 and 582 remain without being removed in a storage state before being used for a specific model. As in the first embodiment, the identification indicators 581 and 582 are board identification information (letters, numbers, and the like) that can specify the model of the gaming machine on which the circuit board (in this case, the main board 535) is used, and the manufacturer or brand. Information consisting of symbols, figures, etc.).

  In this case, as shown in FIG. 21A, the identification mark 581 includes board specifying information made up of the characters “Sophia” (may be “SOPHIA”) as the manufacturer name or brand name, and the model management number. The board specifying information consisting of the letters and numbers “SP09015” as shown in FIG. 5 is represented by a display with a conductive pattern not related to the conductive state in a state where it is arranged in a line on the left and right. Further, as shown in FIG. 21A, the identification mark 582 includes board specifying information consisting of characters “NISHIJIN” (or “Nishijin”) as the manufacturer name or brand name, and a model management number. The board specifying information consisting of letters and numbers “NS08015” is displayed in a state of being displayed in a conductive pattern that is not related to a conductive state in a state where it is arranged in a line on the left and right.

In this embodiment, among the plurality of identification marks 581 and 582 formed as described above, the remaining identification marks other than the identification mark for specifying the circuit board (in this case, the main board 535) are identified. The circuit board can be specified by an identification mark that is difficult to remove and not removed. In other words, at least in the state where the circuit board is finally assembled and used, the remaining identification signs other than the identification signs corresponding to the model of the gaming machine in which the circuit board is used are removed in a difficult-to-identify manner. It has become.
Here, it is preferable to remove only part of the conductive layer 572 constituting the identification mark and the resist layer 573 located on the surface thereof. For example, it is possible to remove the portion where the identification mark is formed, including the base substrate 571, but in this case, the removal operation is not easy. On the other hand, if only a part of the conductive layer 572 constituting the identification mark and the resist layer 573 on the surface thereof are removed, there is an effect that the removing operation is easy.

  Here, the removal procedure is such that when the circuit board is stocked before use, all the formed identification marks are not removed, and the circuit board is used for the production of a specific game machine. In addition, only the remaining identification marks except the corresponding identification mark are removed and removed. Thereby, the circuit board in the said storage state can be shared.

  As a mode for removing the identification mark, a part of the conductive layer constituting the identification mark and the resist layer on the surface thereof are physically peeled off by a tool or a machine tool (for example, a milling machine or an ultrasonic spindle device), or A mode of scraping off may be used, but a mode of removing (for example, peeling) by laser processing using laser light is desirable. In particular, in order to achieve a clean finish of the part from which the identification mark is removed by cleanly removing only a part of the conductive layer constituting the identification mark and the resist layer on the surface while preventing damage to the circuit board, Laser processing is preferred. As described above, since laser processing is non-contact, it can be processed without applying extra stress to the object, and there is no damage due to deformation or cracking of the object. In addition, fine processing can be performed with a laser beam having a small beam diameter, and the processing depth can be finely adjusted by adjusting the output of the laser beam. For this reason, if laser processing is used, only a part of the conductive layer and the resist layer on the surface can be removed cleanly without damaging the circuit board.

In addition, as a procedure for mounting components (including electronic components and wiring connectors) on a circuit board, the above-described specific mounting parts need to be mounted on a circuit board when used for production of a specific gaming machine. The common mounting component described above may be mounted in the storage state, or may not be mounted in the storage state.
In addition, in the removal procedure, a component (one or both of a common mounting component and a specific mounting component, and so on) is mounted before the step of removing only the remaining identification markers excluding the corresponding identification markers. Alternatively, components may be mounted after the same process.
In addition, the display of the part number of each component mounted on the circuit board may be formed in advance on the circuit board in the storage state by silk printing or the like. For example, the circuit board is used for the production of a specific game machine. In this case, it may be formed by silk printing or the like.

Hereinafter, the removal procedure and the like will be described using a specific example shown in FIG.
First, in the storage state in which the main substrate 535 is stocked, all of the identification marks 581 and 582 are left without being removed as shown in FIGS. 21 (a) and (c).
When the main board 535 is used for the production of the model K1 corresponding to the management number “SP09015” of “Sofia”, the specific mounting parts such as the gaming microcomputer 111 corresponding to the model K1 are mounted, and Only the remaining identification mark 582 excluding the identification mark 581 to be removed is removed by, for example, laser processing as shown in FIGS. 22 (a) and 22 (b). At this time, as shown in FIGS. 22A and 22B, the base substrate 571 is not removed, but only a part of the conductive layer 572 constituting the identification mark 582 and the resist layer 573 on the surface thereof are removed. Is preferred.

  When the main board 535 is used for the production of the model K2 corresponding to the management number “NS08015” of “NISHIJIN”, the specific mounting parts such as the gaming microcomputer 111 corresponding to the model K2 are mounted, and Only the other identification mark 581 except for the identification mark 582 to be removed is removed by, for example, laser processing as shown in FIGS. 22 (c) and 22 (d). At this time, as shown in FIGS. 22C and 22D, the base substrate 571 is not removed, and only a part of the conductive layer 572 constituting the identification mark 581 and the resist layer 573 on the surface thereof are removed. Is preferred.

  The common mounting component may be mounted at the time of use (for example, mounted in the same process as the specific mounting component) without being mounted on the main substrate 535 in the storage state, but the main substrate 535 in the storage state. It may be mounted in advance.

  In this case, since all of the identification marks 581 and 582 remain without being removed in the storage state, the main board 535 can be used in common with both the models K1 and K2 (hereinafter referred to as this model). A circuit board in such a state is called a common circuit board). That is, when the common mounting component is not mounted in the storage state, the substrate main body 574 having a common conductive pattern (including identification marks 581 and 582) and also coated with the resist layer 573 is provided as a common circuit board. It becomes. When a common mounting component is mounted in the storage state, a common circuit board is obtained by mounting the common mounting component on the board body 574. In other words, it can be stocked in a state where it can be used in common at two stages before and after mounting the common mounting component.

According to Example B1 demonstrated above, there exist the following effects.
That is, first, since the identification marks 581 and 582 are constituted by a conductive pattern formed by patterning the conductive layer 572, it is difficult to erase or rewrite itself. In particular, it is very difficult to remove or rewrite the identification marks 581 and 582 without leaving a trace. For this reason, fraudulent acts such as unauthorized diversion of the circuit board (in this case, the main board 535) can be prevented.
In addition, a circuit board (in this case, the main board 535) having a common wiring pattern (conductive pattern) can be shared and used effectively in the state of the common circuit board even if the models are different, and can be reused. Disposal due to inventory can be suppressed. In addition, since circuit boards can be mass-produced, costs can be reduced.

  Further, when the identification mark 581 or 582 is removed by laser processing in the removing procedure, an effect is obtained that the work efficiency is good even if an electronic component (for example, a common mounting component) is mounted. This is because, for example, in the removal procedure, it is difficult to remove the identification mark 581 or 582 by machining or the like while the electronic component is mounted because the electronic component becomes an obstacle. On the other hand, since the operation of removing the identification mark 581 or 582 by laser processing is non-contact processing, the work efficiency is good even in a state where electronic parts are mounted.

  In addition, since the identification marks 581 and 582 of this example are based on the display by the conductive pattern, the following effects are obtained as compared with the mode of Example B2 (display by facing the base substrate surface) described later. There is. That is, it is more effective to form the identification mark with the conductive pattern than when the identification mark is formed by showing the base substrate surface from the conductive pattern (a part of the conductive layer and the resist layer on the surface). ) Is only removed, the amount to be removed is small, and the effort to clean up the peeling dust and shavings generated by the removal can be minimized.

<Example B2>
Next, Example B2 will be described with reference to FIGS.
The embodiment B2 is characterized in that the main substrate 535 includes a substrate body 574 having identification marks 583 and 584 by facing the base substrate surface, and other configurations may be the same as the embodiment B1. That is, in this example, as shown in FIGS. 17A to 17C, the circuit board (this circuit board (this) is displayed by displaying the base board surface (the surface of the base board 571) from the conductive pattern (conductive layer 572). In this case, an identification mark that can identify the main board 535) is displayed. That is, the configuration of the identification mark is the same as that of the second embodiment.

The display contents of the identification marks 583 and 584 are the same as the identification marks 581 and 582 of the first embodiment.
In Example B2, as in Example B1, the identification marks 583 and 584 that do not correspond to the model to be used are removed (see FIGS. 23A to 23D), and the same operation as in Example B1 is performed. There is an effect.

<Example B3>
Next, Example B3 will be described with reference to FIG.
In Example B3, one of the identification marks 581 and 582 is formed on the edge on the long side of the substrate body 574, and the other identification mark 582 is formed on the edge on the short side of the substrate body 574. The other features are the same as in Example B1.
Also in this Example B3, as in Example B1, the identification marks 581 and 582 that do not correspond to the model to be used are removed (see FIGS. 24B and 24C), and the same effect is obtained. Can do.
In addition, when the identification mark is formed and arranged separately in the longitudinal direction and the short direction as in Example B3, it can be identified by the position of the identification mark that has not been removed. It is easy to identify the circuit board of the manufacturer or brand).

<Example B4>
Next, Example B4 will be described with reference to FIG.
Example B4 is an example in which three identification marks 585, 586, 587 are formed. The configuration may be the same as that of Example B1 except that there are three identification marks and two identification marks to be removed. As shown in FIG. 25, the identification marks 585, 586, 587 are all of the same brand “Sophia” in this example, and display the difference of models within the same brand.

Also in this Example B4, as in Example B1, the identification marks 585 to 587 that do not correspond to the model to be used are removed (see FIGS. 25 (b) to (d)), and the same effect is obtained. Can do.
As described above, there may be three or more identification labels of the embodiment B. Further, the plurality of identification signs may all be of the same brand as in Example B4, or there may be different brands of the plurality of identification signs as in Example B1.

Next, the inventive concept extracted from the embodiment B will be sequentially described.
