Description

The present invention relates to a gaming machine including a board case that accommodates a control board that controls a game.

In a slot machine, which is one of the gaming machines, a control board that controls the progress and effects of the game is mounted, and the control board is housed in a board case. A push button such as a reset switch may be mounted on this type of control board. For example, in the gaming machine described in Patent Document 1, a push button is mounted on the control board, and the push button is housed in the board case together with the control board. The board case is provided with an opening just above the push button so that the push button can be pressed. According to this configuration, since the illegal jig can be easily inserted through the opening of the substrate case, there is a possibility that an illegal act will be performed. Therefore, in the gaming machine described in Patent Document 1, an inner wall is provided on the control board housing space side of the control board so as to surround the push button, and the other mounted components are separated from the push button.

JP-A-2018-47377 (see paragraphs 0035 to 0038 and FIG. 12)

However, in the gaming machine described in Patent Document 1, the structure of the board case becomes complicated and the cost of the board case increases. Further, although the inner wall can prevent direct access to other mounted components, there is still a possibility of fraudulent acts when wiring for transmitting control signals is formed around the push button or on the control board directly below. Yes, it is not sufficient as a measure against fraud. Further, since the push button itself needs to be depressed, if the push button is covered with a cover such as a fitting window, the convenience of the push button is reduced.

The present invention has been made in view of the above problems, and when the control board on which the push button is mounted is housed in the board case, the push button is pressed without complicating the structure of the board case. It is an object of the present invention to prevent fraud from the opening provided in the.

In order to achieve the above-mentioned object, a gaming machine according to the present invention is a gaming machine including a control device for controlling the progress of a game, in which a plurality of wirings for handling signals related to the control by the control device are formed. A board, a push button mounted on the mounting surface of the control board, a 7-segment display mounted on the mounting surface of the control board, and a board case covering the control board. The push button includes a first wiring for handling a signal and a second wiring for handling another signal. When the push button is pushed, a signal is transmitted to the control device, and the board case is provided with the An opening is formed through which the push button can be pressed, a metal plate surrounding the push button is disposed on the control board, and the metal plate is viewed from a direction perpendicular to the mounting surface. Is formed in a wider area than the opening, and in the region of the control board that overlaps the opening when viewed from a direction perpendicular to the mounting surface, the first layer is formed over the entire layer. Two wirings are not formed, the first wiring and the second wiring are formed so as to avoid a region overlapping with the rectangular 7-segment display and not to pass a predetermined side of the 7-segment display, and the metal plate and The second wiring is not formed over the entire layer in the overlapping region .

According to this configuration, the wiring (second wiring) that handles signals related to control other than the push button is not formed in the area overlapping the opening provided for pressing the push button, so the second wiring is targeted. It is possible to prevent cheating. Moreover, since it is not necessary to provide an inner wall for fraud prevention in the board case, the manufacturing cost of the board case can be suppressed. Further, for example, if the metal plate is grounded, even if an illegal signal such as a wire is inserted around the push button and an illegal signal is transmitted, if it hits the metallic plate, it will be discharged and the control device Since no fraudulent signal ever reaches, it is possible to reliably prevent this kind of fraudulent activity. Further, since the static electricity generated when the push button is pressed can be discharged by the metal plate, it is possible to prevent damage to the mounted components of the control board and the wiring pattern. Furthermore, when an unauthorized jig enters, it can function as a physical defense plate.

Further, the second wiring may be formed so as to bypass the opening.

According to this configuration, the degree of freedom in designing the wiring pattern is limited, but the safety of signals to the control device can be further improved.

In addition, a setting relating to a payout rate of a game can be changed, and a setting change mode in which the mode is changed based on an operation of a mode changing operation means, and a normal mode in which a game is performed based on the setting determined in the setting change mode. In some cases, the push button may function as a transmission button of a setting change signal for instructing a setting change, and the control device changes the setting of the signal received from the push button only in the setting change mode. It may be processed as a signal.

According to this configuration, even if an attempt is made to make a mistake on the setting change signal transmitted from the push button signal, it is processed as the setting change signal unless the mode change operation means is operated to shift to the setting change mode. Therefore, even if the push button and the first wiring are exposed and installed for the sake of convenience, security can be ensured for the first wiring.

When the setting change button 56 (reset switch) is pressed once in the setting change mode, the setting value set before power-on is provisionally set to the next higher setting value (for example, setting 3 to setting 4 is temporarily changed). Configuration). The temporary setting value is stored in the temporary setting value storage area set in the ROM 67 of the main CPU 61. After that, each time the setting change button 56 is pressed, the setting value is temporarily set to the next higher setting value. At this time, each time the setting change button 56 is pressed, the temporary setting value stored in the temporary setting value storage area is rewritten with a new value.

However, when the setting change button 56 is pressed when the temporary setting value is 6, the setting value returns to 1 and is temporarily set. Finally, the set value is confirmed by turning on the start switch 19, and the provisional set value at that time becomes the set value of the slot machine 1. At this time, the stored contents of the set value storage area of the RWM 65 of the main control board 63 are rewritten with the changed set values. In the setting change mode, the temporary set value is displayed on the 7-segment LED 83c mounted on the relay board 83 so that the set temporary set value can be confirmed.

After the setting is changed, when the setting change key is inserted into the keyhole and rotated counterclockwise by about 60°, the setting change key switch 52 is turned off. As a result, the setting change mode is switched to the normal mode in which a game can be played.

Since the setting change key switch 52 is arranged in the operation box 49 arranged inside the housing 3, it cannot be operated unless the front door 5 is opened. Therefore, only the game manager can change the setting. On the other hand, when the power supply switch 50 is ON and the setting change key switch 52 is ON, the set value at that time is displayed on the 7-segment LED 83c so that the set value can be confirmed. In order to change the setting, it is necessary to operate both the setting change key switch 52 and the setting change button 56, but the setting change key switch 52 is provided in the operation box 49 and the setting change button 56 is operated. It is arranged on a relay board 83 different from the box 49. That is, since these switches 52 and 56 are physically separated from each other, security against setting changes is ensured.

(Error handling)
When an event (error) that hinders the progress of the game occurs, the fact is notified by a notification sound. Among the errors, there are errors that require interruption of the game and possible errors that the game cannot progress. Various error contents are reported using the two 7-segment LEDs of the payout display 46. For example, a medal insertion error is a state in which a medal abnormally passes through the insertion sensor 53, and E1 is set as an error code. The payout medal error 1 is a state in which ON of the payout sensor 54 is continuously detected for a certain period of time or more, and E2 is set as an error code. The payout medal error 2 is a state in which the payout sensor 54 is ON when the medal is not paid out, and E3 is set as an error code. The medal-out error is a state in which the medal does not pass through the payout sensor 54 even if the hopper motor 57 is operated, and E4 is set as the error code. In addition, the RWM error in which the RWM 65 of the main control board 63 is abnormal, the reel error in which the rotation of the reels 13L, 13M, and 13R is abnormal, and the auxiliary tank of the hopper unit 43 are There is an overflow error that is full of medals, and a unique error code is set for each.

Then, when an error occurs, an error code is displayed on the two 7-segment LEDs of the payout display unit 46 to notify the content of the error. After removing the error event, the normal game is restored by pressing the setting change button 56.

As described above, the setting change button 56 may be used both as a switch for setting change and a switch for canceling an error when an error occurs. Here, the main CPU 61 of the main control board 63 performs different processing on the signal from the setting change button 56 in the setting change mode in which the game cannot proceed and in the normal mode in which the game can proceed. To execute.

In the setting mode, when the main CPU 61 receives a signal from the setting change button 56, the main CPU 61 executes a process of rewriting the temporary setting value in the temporary setting value storage area stored in the RWM 65 to the temporary setting value which is +1. On the other hand, in the normal mode, when the signal from the setting change button 56 is received, the processing for canceling the error is executed. That is, the process of returning the display of the error code displayed on the payout display 46 to the default, the process of transmitting a command for notifying the error recovery to the sub control board 73 to stop the error warning sound, the reception of the insertion of medals. Execute processing to remove the prohibition.

The relay board 83 is housed in the board case 84, and openings (not shown) are formed in the board case 84 at positions corresponding to the respective connectors 83a and 83b. An opening 84a (see FIGS. 3 and 4) is also formed at a position corresponding to the setting change button 56 of the board case 84. Here, the corresponding position is a portion of the board case 84 that overlaps each of the connectors 83a and 83b and the setting change button 56 when viewed from a direction perpendicular to the mounting surface 830 of the relay board 83.

The openings corresponding to the respective connectors 83a and 83b have a horizontally long rectangular shape that is substantially the same as the outer shape of the corresponding first connector 83a (connector header), and are formed slightly larger than the outer shape of the corresponding first connector 83a. There is. When the relay board 83 is housed in the board case 84, the connectors 83a and 83b are both exposed, and the connector socket can be attached and detached without removing the relay board 83 from the board case 84. There is.

Further, as shown in FIGS. 3 and 4, in this embodiment, the setting change button 56 is formed in a circular columnar shape when viewed from a direction perpendicular to the mounting surface 830 of the relay board 83. ing. Further, the opening 84a (the circle formed by the alternate long and short dash line in FIG. 3) corresponding to the setting change button 56 of the board case 84 is from a direction perpendicular to the mounting surface 830 of the relay board 83 of the setting change button 56. The circle is the same as the formation (circle) when viewed, and is formed as a circle slightly larger than the circle formed by the setting change button 56. In the state where the relay board 83 is housed in the board case 84, the setting change button 56 is exposed and can be pressed without taking out the relay board 83 from the board case 84.

Further, in this embodiment, the setting change button 56 before being pressed has a height H2 from the mounting surface 830 of the relay board 83 that is higher than the mounting surface 830 of the board case 84, as shown in FIG. It is formed slightly higher than the height H1. On the other hand, the setting change button 56 is formed so that the height H3 from the mounting surface 830 is lower than the height H1 of the substrate case 84 in the pressed state. Therefore, when the setting change button 56 is pressed, the relay board 83 can be easily accessed from the opening 84a of the board case 84. Here, a wiring for transmitting a signal from each switch or sensor to a region corresponding to the opening 84a of the relay board 83 (a region overlapping the opening 84a when viewed from a direction perpendicular to the mounting surface 830) ( For example, if a part of the wiring pattern P2) is formed, an illegal signal can be sent to the wiring by inserting an illegal jig into the gap between the opening 84a and the setting change button 56. For example, the display of the credit indicator 45 or the payout indicator 46 may be changed illegally, or an illegal signal may be sent from the wiring pattern transmitted by the signal from the medal selector 48, so that the main control may be performed even if the medal has not been inserted. There is a risk of misconduct such as making the board 63 misidentify the insertion of a medal.

Therefore, in this embodiment, when viewed from the direction perpendicular to the mounting surface 830 of the relay board 83, the predetermined area A in the relay board 83 including the area overlapping the opening 84a for the setting change button 56 is It is set in the formation prohibited area of the wiring pattern for signal transmission. In this embodiment, the predetermined area A is set to an area (the same size as the opening 84a) that overlaps the opening 84a when viewed from a direction perpendicular to the mounting surface 830. The range of the predetermined area A (formation prohibited area) can be appropriately changed as long as it is larger than the opening 84a.

Particularly, of the second connector 83b for transmitting signals to the main control board 63, to which signals from the bet switch 15, the maximum bet switch 17, the start switch 19, the closing sensor 53, and the stop switches 21L, 21M, and 21R are input. Each wiring pattern that connects each terminal (pin) with a corresponding predetermined terminal (pin) of the first connector 83a, when viewed from a direction perpendicular to the mounting surface 830 of the relay board 83, None of them are formed so as to bypass the inner region of the opening 84a and to bypass the inner region. In addition, the wiring patterns for transmitting the control signals (credit indicator 45, payout indicator 46) from the main control board 63 are both opened when viewed from the direction perpendicular to the mounting surface 830 of the relay board 83. It is formed so as not to pass through the inner region of the portion 84a but to bypass. In this embodiment, not only these wiring patterns of the control signal system (for example, the wiring pattern P2) but also all wiring patterns except the wiring pattern P1 and the wiring pattern of the power supply system are the predetermined area A (formation prohibited area). Is formed to avoid.

For example, as shown in FIG. 3, the terminal of the second connector 83b to which one of the signals from the bet switch 15, the maximum bet switch 17, the start switch 19, the closing sensor 53, and the stop switches 21L, 21M, and 21R is input. The wiring pattern P2 that connects the (pin) and a predetermined terminal (pin) of the first connector 83a for transmitting the signal to the main control board 63 is in a direction perpendicular to the mounting surface 830 of the relay board 83. When viewed from above, even if the route that crosses the predetermined region A (formation prohibited region) can be made shorter, the route is formed to bypass the predetermined region A (formation prohibited region).

At this time, when the relay substrate 83 has a multilayer structure and the wiring pattern P2 is formed over a plurality of layers, it is formed on any of the mounting surface 830, each inner layer, and the back surface 840 opposite to the mounting surface 830. The portion to be formed is also formed so as not to overlap the predetermined area A (formation prohibited area).

However, the wiring pattern P1 that connects the setting change button 56 and the corresponding terminal of the first connector 83a and the wiring pattern of the power supply system are formed in an area that overlaps the predetermined area A (formation prohibited area). May be That is, the setting change button 56, the wiring pattern P1 for connecting the setting change button 56 and the terminal of the first connector 83a for transmitting to the main control board 63, the wiring pattern for supplying power to the 7-segment LED 83c, and the like. May be partially or entirely formed in the predetermined area A (formation prohibited area).

It should be noted that all (or part) of the wiring pattern P1 and the wiring pattern P2 that connect the setting change button 56 and the corresponding terminal of the first connector 83a when viewed from a direction perpendicular to the mounting surface 830. In addition, it is preferably formed so as to avoid a region overlapping with the 7-segment LED 83c. Further, it is more preferable not to form a wiring pattern other than the wiring pattern that handles the signal relating to the 7-segment LED 83c in the region overlapping with the 7-segment LED 83c. With this arrangement, even if the illegal IC is hidden right under the 7-segment LED 83c and a signal relating to the control by the main control board 63 is illegally acted, the connection portion between the illegal IC and the wiring pattern can be visually recognized. Therefore, the discovery becomes easy.

Therefore, according to the above-described embodiment, the relay board 83 has the detection signal of the closing sensor 53, the signal indicating that the stop switches 21L, 21M, and 21R have been pressed, and the fact that the bet switch 15 has been pressed. A signal, a signal indicating that the maximum bet switch 17 has been pressed, a signal indicating that the start switch 19 has been operated, a signal indicating that the setting change button 56 has been operated, etc., for the progress of the game of the main control board 63. A second connector 83b for inputting related signals and a first connector 83a for transmitting these signals to the main control board 63 are mounted, and further, a terminal of the second connector 83b on the input side and an output side. The terminals of the first connector 83a are connected by the wiring pattern (for example, the wiring pattern P2) formed on the relay board 83. Further, the relay board 83 is provided with a setting change button 56 for transmitting a signal for instructing a setting change and an error cancellation signal, which are other signals related to the progress of the game of the main control board 63. Then, a terminal for outputting the signal is provided on the first connector 83a, and the setting change button 56 and the terminal are connected by the wiring pattern formed on the relay board 83.

Here, when viewed from the direction perpendicular to the mounting surface 830, in the area (predetermined area A) that overlaps the opening 84a of the board case 84 of the relay board 83, the setting change button 56 and the corresponding first button A wiring pattern for transmitting a signal regarding the progress of the game by the main control board 63 is not formed except for the wiring pattern for connecting the terminals of the 1 connector 83a. By doing this, an unauthorized jig is inserted through the gap between the setting change button 56 and the opening 84a, which is enlarged by pressing the setting change button 56, and is used as a transmission path for a signal relating to the progress of the game by the main control board 63. It is possible to prevent a fraudulent act of transmitting a fraudulent signal. Further, in order to prevent such fraudulent acts, it is not necessary to provide an inner wall for fraud prevention on the substrate case 84, so that the manufacturing cost of the substrate case 84 can be reduced.

Further, as a measure for preventing the fraudulent act, wiring for transmitting a signal from the setting change button 56 in the relay board 83 by mounting the setting change button 56 on the end portion of the relay board 83, for example. It can be considered to divide into a region where a pattern is formed and a region where a wiring pattern for transmitting other signals is formed. However, in this case, the degree of freedom in arranging the mounted components and the like on the relay board 83 is reduced. On the other hand, according to this embodiment, in order to prevent the illegal action, a region for forming a wiring pattern for transmitting the signal from the setting change button 56 and a wiring pattern for transmitting other signals are formed. Since it is not necessary to divide the area into the area to be mounted, the degree of freedom in the arrangement of mounted components and the like is improved.

Further, the wiring pattern (excluding the wiring pattern of the setting change button 56) to which a signal regarding the progress of the game by the main control board 63 is transmitted is the opening 84a when viewed from the direction perpendicular to the mounting surface 830. Since the wiring patterns are provided so as not to intersect with each other, the wiring patterns for signal transmission can be easily formed while avoiding the area (predetermined area A) overlapping the opening 84a.

In addition, since the wiring pattern for transmitting the signal from the setting change button 56 is formed in the area (predetermined area A) overlapping the opening 84a, there is a possibility that a fraudulent act regarding the setting change is performed. However, in this embodiment, the main CPU 61 sets the setting change key switch 52 operable by the game manager to ON and sets the signal from the setting change button 56 only in the setting change mode. Since the processing is performed as the change instruction signal, the security of the signal transmitted from the setting change button 56 can be improved. Further, since the security of the transmission signal from the setting change button 56 can be ensured, the setting change button 56 and the wiring pattern P1 connected to this can be exposed and installed with emphasis on convenience.

The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention. For example, as shown in FIG. 5, in the above-described embodiment, the metal plate 85 may be arranged around the setting change button 56. In this case, for example, on the relay board 83, a rectangular metal plate having the setting change button 56 arranged in a circular shape is cut out and mounted as a metal plate 85, and the metal plate 85 is arranged around the setting change button 56. To do. The metal plate 85 is connected to, for example, a grounded wiring (for example, a ground electrode) on the mounting surface 830. As a result, the metal plate 85 functions as a ground plate. The metal plate 85 is preferably formed in a wider area than the opening 84a when viewed from the direction perpendicular to the mounting surface 830. Further, the metal plate 85 does not need to be entirely formed of metal. For example, a resin block having a metal plate arranged on the upper surface is mounted on the mounting surface 830, and grounded wiring on the mounting surface 830 is used. A configuration may be used in which the metal plate is connected by a conductor.

By doing so, the static electricity generated when the setting change button 56 is pressed can be discharged by the metal plate 85, so that damage to the mounted components and the wiring pattern of the relay board 83 can be prevented. Further, when an illegal jig enters, it can function as a physical defense plate. Further, for example, even if an illegal tool such as a wire is inserted around the setting change button 56 and an illegal signal is transmitted, if the metallic plate 85 is contacted with the illegal electric discharge, the illegal electric discharge is surely prevented. can do. In addition, when the metal plate 85 is discharged, a unit may be provided to determine whether the discharge is caused by static electricity due to noise or an unauthorized signal. In this case, when it is determined that the signal is an illegal signal, the fact may be notified or the game may be disabled so that the subsequent illegal activities cannot be performed.

Further, the state in which the unauthorized jig is inserted through the gap between the setting change button 56 and the opening 84a is the state in which the setting change button 56 is pressed. Further, the front door 5 may be closed and the setting change button 56 may be pressed. Therefore, for example, a unit is provided to determine whether or not the state where the setting change button 56 is pressed is for a certain period of time or more, and whether or not the setting change button 56 is pressed with the front door 5 closed. If it is determined that these situations have occurred, the main control board 63 may be configured to perform control such that subsequent fraudulent acts cannot be performed. Further, the main control board 63 determines that the fraudulent act has been performed when it detects a state that does not normally occur, such as when the signal for pressing the setting change button 56 and other signals are received at the same time, and the subsequent fraud The action may be prohibited.

Further, in this embodiment, the setting change button 56 mounted on the relay board 83 has been described as an example, but the present invention, for example, includes the main control board 63, the sub control board 73, and the like that are stored in a board case. It can be widely applied to push buttons such as substrates.

Further, in this embodiment, the setting change button 56 has a circular columnar shape when viewed from the direction perpendicular to the mounting surface 830, but has a circular column shape, for example, from the direction perpendicular to the mounting surface 830. The shape when viewed can be appropriately changed, such as a rectangular column shape.

Further, the height before pressing the setting change button 56 may be higher than the height position (H2) of the substrate case 84 as shown in FIG. 4, or may be the same (H1=H2). Alternatively, it may be low (H1<H2).

Further, in this embodiment, the setting change button 56 has been described as an example of the push button for transmitting the signal regarding the control by the main control board 63, but if the push button for transmitting the signal regarding the control by the main control board 63 is used, Not limited to this.
