  FIG. 2 is a block diagram illustrating a configuration example of various substrates and peripheral devices. The pachinko gaming machine 1 is equipped with various control boards such as a main board 11, an effect control board 12, voice control boards 13A to 13C, a lamp control board 14, and a relay board 15 as shown in FIG. In addition, for example, various substrates such as a payout control substrate, an information terminal substrate, a launch control substrate, an interface substrate, and a touch sensor substrate may be mounted.

  On the main board 11, a game control microcomputer 100, a switch circuit 110, a solenoid circuit 111 and the like are mounted. On the main board 11, for various detections such as a gate switch 21, a start port switch (first start port switch 22A and second start port switch 22B), count switches 23A and 23B, a first detection switch 24A, and a second detection switch 24B. A signal taken in from the switch is transmitted to the game control microcomputer 100 via the switch circuit 110. The gate switch 21 detects a game ball (gate passing ball) that has passed through the passing gate 36. Based on the detection of the gate passing ball by the gate switch 21, variable display of the normal symbol by the normal symbol display 20 can be executed. The first start port switch 22A detects a game ball that has passed (entered) the first start winning port. The second start port switch 22B detects a game ball that has passed (entered) the second start winning port. The count switches 23A and 23B detect game balls that have passed (entered) through the big winning opening. When a game ball that has passed through various winning holes such as the first starting winning hole, the second starting winning hole, and the big winning hole is detected, a predetermined number of balls corresponding to each winning hole is determined. As a game ball is paid out.

  On the main board 11, a solenoid drive signal from the game control microcomputer 100 is transmitted to the solenoid 81 for the ordinary electric accessory and the solenoid 82 for the big prize door through the solenoid circuit 111. The solenoid 81 for the ordinary electric accessory is in a state where the game ball is difficult to pass (or a state where it does not pass) and a state where it is easy to pass (or a state where it passes) through the second start winning opening formed in the normally variable winning ball device 6B. And changeable. The solenoid 82 for the special winning opening door allows the special winning opening formed in the special variable winning ball apparatus 7 to be changed between a state in which a game ball cannot pass and a state in which it can pass. A command signal for performing display control of the first special symbol display device 4A, the second special symbol display device 4B, the normal symbol display device 20 and the like is transmitted from the main board 11. A communication unit 49 that can communicate with the hall management computer is connected to the main board 11.

  The game control microcomputer 100 mounted on the main board 11 is, for example, a one-chip microcomputer, and includes a ROM 101 that stores a game control program and fixed data, and a RAM 102 that provides a game control work area. A CPU 103 that executes a game control program to perform a control operation, a random number circuit 104 that updates a numerical data indicating a random number value independently of the CPU 103, and an I / O (Input / Output port) 105 It is prepared for. As an example, in the game control microcomputer 100, a process for controlling the progress of the game in the pachinko gaming machine 1 is executed by the CPU 103 executing a program read from the ROM 101. In the game control microcomputer 100 mounted on the main board 11, various random values used for controlling the progress of the game are obtained by, for example, a random number circuit 104 or a game random counter provided in a predetermined area of the RAM 102. The numerical data shown is counted (generated) in an updatable manner. The random number used for controlling the progress of the game is also called a game random number.

  The effect control board 12 receives the control signal (effect control command) transmitted from the main board 11 via the relay board 15, and the image display device 5, the first speakers 81R and 81L, and the second speakers 82R and 82L. It is possible to control the presentation operation by the third speaker 83, the game effect lamp 9 and the decorative electric parts such as the decoration LED. On the effect control board 12, an effect control CPU 120, ROM 121, RAM 122, display control unit 123, random number circuit 124, I / O 125, and the like are mounted. The sound control boards 13A to 13C are control boards for sound output control provided separately from the effect control board 12, and based on commands and control data from the effect control board 12, the first speakers 81R and 81L. A processing circuit for executing audio signal processing for outputting audio from the second speakers 82R and 82L and the third speaker 83 is mounted. The sound control board 13A controls the first speakers 81R and 81L. The sound control board 13B controls the second speakers 82R and 82L. The sound control board 13C controls the third speaker 83. The sound control boards 13A and 13B may include two boards corresponding to the individual speakers included in the first speakers 81R and 81L and the second speakers 82R and 82L. If the effect control CPU 120 mounted on the effect control board 12 can execute the audio signal processing, the sound control boards 13A to 13C may be provided with band filters, amplifier circuits, and the like. The lamp control board 14 is a control board for lamp output control provided separately from the effect control board 12, and based on commands and control data from the effect control board 12, the game effect lamp 9 and the decoration LED A lamp driver circuit that turns on and off is mounted.

  The effect control CPU 120 mounted on the effect control board 12 uses the effect control program read from the ROM 121, fixed data, and the like to execute a process for controlling the effect operation by the effect electric parts. The display control unit 123 mounted on the effect control board 12 determines the control content of the display operation in the image display device 5 based on the display control command from the effect control CPU 120. For example, the display control unit 123 performs control for executing decorative display variable display and various effect displays by determining the switching timing of effect images to be displayed on the display screen of the image display device 5.

  A controller sensor unit 35A and a push sensor 35B are connected to the effect control board 12. The controller sensor unit 35A includes a tilt direction sensor and a trigger sensor. The tilt direction sensor makes it possible to detect the tilt direction of the operation rod using a plurality of sensors when the tilt operation is performed on the operation rod of the stick controller 31A. The trigger sensor makes it possible to detect the presence / absence of a push / pull operation on the trigger button provided on the operation stick of the stick controller 31A. That is, the controller sensor unit 35A can detect a player's operation using the stick controller 31A, such as a tilting operation with respect to the operating rod of the stick controller 31A or a push-pull operation with respect to the trigger button. The push sensor 35B can detect a player's operation using the push button 31B, such as a pressing operation on the push button 31B. On the effect control board 12, for example, a random counter for effects provided in a predetermined area of the random number circuit 124 or the RAM 122 counts numerical data indicating various random numbers used for controlling the execution of the effect in an updatable manner ( Generated). The random number used to control the execution of the effect is also referred to as an effect random number.

  In the pachinko gaming machine 1, a predetermined game using a game ball as a game medium is performed, and a predetermined game value can be given based on the game result. As an example of a game using a game ball, based on a hitting operation handle 54 provided at a lower right position of the gaming machine frame 3 in the pachinko gaming machine 1 being operated by a player (for example, a rotating operation), A game ball as a game medium is launched toward the game area 10 by a launch motor provided in a predetermined hitting ball launching device. When a game ball that has flowed down the game area 10 passes (enters) various winning holes, a game ball as a prize ball is paid out. If the variable symbol display result for special symbols and decorative symbols is “big hit”, the big prize opening is opened and the game ball easily passes (enters), which is an advantageous state advantageous to the player. It becomes a big hit game state.

  The advantageous state is not limited to the big hit gaming state, and may include a special gaming state such as a short time state or a probable change state. In addition, the upper limit number of round games that can be executed in the big hit game state is the first round number (for example, “15”) larger than the second round number (for example, “7”), and it can be executed in the short time state. The upper limit number of variable displays is a first number (for example, “100”) greater than the second number (for example, “50”), and the big hit probability in the probability variation state is higher than the second probability (for example, 1/50). The number of consecutive chunks, which is one probability (for example, 1/20), and the number of repeated control that is repeatedly controlled to the big hit gaming state without being controlled to the normal state is greater than the second consecutive number of channels (for example, “5”) It may include a game situation that is more advantageous for the player, such as a part or all of the fact that the number of consecutive channels (for example, “10”) is reached.

  Next, a configuration example of the speaker 80R will be described. The speaker 80R may be used as the speaker 81R included in the first speakers 81R and 81L and the speaker 82R included in the second speakers 82R and 82L. The speaker 81L included in the first speakers 81R and 81L and the speaker 82L included in the second speakers 82R and 82L only need to be able to use speakers configured symmetrically with the speaker 80R. FIG. 3 is a front view of the speaker 80R. FIG. 4 is a rear view of the speaker 80R. FIG. 5A is a view showing a cross section AA in FIG. 4, and FIG. 5B is a view showing an arrangement example of the elastic members 71. FIG. 6 is a right side view of the speaker 80R. FIG. 7 is a view showing a BB cross section shown in FIG. 6. FIG. 8 is a left side view of the speaker 80R. FIG. 9 is a front upper perspective view of the speaker 80R. FIG. 10 is a rear upper perspective view of the speaker 80R.

  A front cover member 60A is provided on the front side of the speaker 80R. 60 A of front cover members should just be screwed to the housing | casing (enclosure) 60 of the speaker 80R shown in FIG.6 and FIG.8 using the fixing screws 61A-61D. The front cover member 60A is formed using a synthetic resin such as an acrylic resin. The front cover member 60A only needs to be provided with a large number of through holes in front of the speaker body 80S in order to ensure good sound transmission from the speaker body 80S. The synthetic resin is not limited to an acrylic resin, and any resin may be used as long as it uses an ABS (acrylonitrile / butadiene / styrene) resin, a polypropylene resin, a polyethylene resin, or any other synthetic resin. Further, the front cover member 60A is not limited to one formed using a synthetic resin, and may be formed using a metal such as a punching metal or an expanded metal.

  60 A of front cover members should just be formed using the synthetic resin which has a light transmittance and can be seen through. Thereby, without removing the front cover member 60A, the speaker main body 80S and the like can be viewed, and an illegal act on the speaker 80R can be easily confirmed. In the front cover member 60A, the periphery of the screw hole into which the fixing screws 61A to 61D are inserted may be curved. Accordingly, it is only necessary to prevent an illegal act using an unauthorized tool such as a hook member.

  The housing 60 of the speaker 80R may be any one as long as the housing front member 60B and the housing rear member 60C are fitted to each other at the housing joint portion 60D and integrated. The housing front member 60B and the housing rear member 60C may be formed using a synthetic resin such as an acrylic resin, similarly to the front cover member 60A. The housing front member 60B and the housing rear member 60C may be formed using a synthetic resin that allows the inside of the housing 60 to be seen through, like the front cover member 60A. Thereby, the inside of the housing 60 can be viewed without separating the housing front member 60B and the housing rear member 60C, and an illegal act on the speaker 80R can be easily confirmed. The speaker body 80S is attached to the housing 60 by being screwed together with the front cover member 60A on the rear side of the front cover member 60A.

  When the speaker 80R is used as the speaker 81R included in the first speakers 81R and 81L, the speaker main body has one side surface on the front side among the side surfaces facing the front side and the rear side inside the housing 60. 80S is disposed, and the sound control board 13A is disposed on the other side surface on the rear side. When the speaker 80R is used as the speaker 82R included in the second speakers 82R and 82L, the speaker main body has one of the side surfaces facing the front side and the rear side inside the housing 60 on the front side. 80S is arrange | positioned and the audio | voice control board | substrate 13B should just be arrange | positioned at the other side surface used as the back side. Hereinafter, the sound control board 13B when the speaker 80R is used as the speaker 82R included in the second speakers 82R and 82L is the sound control board 13A when the speaker 80R is used as the speaker 81R included in the first speakers 81R and 81L. It has the same characteristics.

  In the housing rear member 60C shown in FIG. 4, an opening 60C0 (see, for example, FIG. 6) penetrating the inside and the outside of the housing 60 is formed in the board attaching portion to which the audio control board 13A is attached. . Of the side surfaces facing the front side and the rear side, the speaker main body 80S is disposed on one side surface that is the front side, and the opening 60C0 is formed on the other side surface that is the rear side. The Grooves 60CA, 60CB, 60CC, and 60CD are formed in the housing rear member 60C. Accordingly, it is only necessary to improve the rigidity and acoustic characteristics of the housing rear member 60C and reduce the occurrence of abnormal noise caused by unnecessary vibrations. Housing fixing members 63A and 63B are provided at the rear end of the housing rear member 60C.

  An audio control board 13A and a board cover 70 are provided on the board mounting portion on the rear side of the housing rear member 60C shown in FIG. The sound control board 13A shown in FIG. 4 may be accommodated in the board cover 70 and screwed to the housing rear member 60C using the fixing screws 72A to 72C. The gap between the peripheral edge of the opening 60C0 and the sound control board 13A is sealed with an elastic member 71 at the board mounting portion on the rear side of the housing rear member 60C shown in FIG.

  The elastic member 71 can be deformed when the sound control board 13A and the board cover 70 shown in FIG. 4 are screwed using the fixing screws 72A to 72C, and the case front member 60B and the case constituting the case 60 are deformed. What is necessary is just to be formed using a softer material than the body rear member 60C and the sound control board 13A. For example, the elastic member 71 is formed using a synthetic resin such as urethane resin or a synthetic rubber such as styrene butadiene rubber. The synthetic resin forming the elastic member 71 is not limited to the urethane resin, and may be any resin using polypropylene resin, nylon resin, EVA (ethylene vinyl acetate) resin, silicon resin, or any other synthetic resin. The synthetic rubber forming the elastic member 71 is not limited to styrene butadiene rubber, and any chloroprene rubber, ethylene propylene rubber, fluorine rubber, or any other synthetic rubber may be used.

  In the board attachment portion of the housing rear member 60C, when the audio control board 13A and the board cover 70 are screwed using the fixing screws 72A to 72C, one main surface (one of the front and back surfaces) of the elastic member 71 is It is only necessary that the peripheral surface of the opening 60C0 is in close contact with the outer surface of the housing rear member 60C, and the other main surface (the other of the front and back surfaces) of the elastic member 71 is in close contact with one surface (mounting surface) of the sound control board 13A. As described above, the elastic member 71 is in pressure contact with one surface of the housing rear member 60C constituting the housing 60 and the sound control board 13A within a predetermined range corresponding to the board mounting portion of the housing rear member 60C. You can do it. Further, for example, the elastic member 71 shown hatched in FIG. 5B is formed to be slightly larger (specifically, about several millimeters) than the sound control board 13A indicated by the alternate long and short dash line, and is indicated by the dotted line. What is necessary is just to be formed in the magnitude | size comparable as the cover 70. FIG. Similarly to the case front member 60B and the case rear member 60C, the substrate cover 70 may be formed using a synthetic resin such as an acrylic resin, and may be formed using a synthetic resin that allows the inside of the cover to be seen through. This makes it possible to visually recognize that the elastic member 71 is on the outer peripheral side of the opening 60C0 formed in the housing rear member 60C, and confirming the sealing property in the gap between the peripheral edge of the opening 60C0 and the sound control board 13A. Becomes easier. Since it becomes easy to confirm the sealing property in the gap between the peripheral edge of the opening 60C0 and the sound control board 13A, an illegal act on the speaker 80R can be prevented.

  A square raised portion 64 is provided on the inner side of the housing rear member 60C around the intersection with the central axis of the speaker body 80S. The raised portion 64 is a region surrounded by a small inner square and an outer large square among the two squares indicated by dotted lines in FIG. 4. The housing rear member 60C is raised and formed so as to protrude from the region. The center of the raised portion 64 is arranged so as to be on the central axis of the speaker main body 80S. As described above, the protruding portion 64 is provided on the inner side of the casing rear member 60C, and the central axis of the speaker body 80S may be disposed so as not to pass through the opening 60C0. Thus, it is only necessary to be able to adjust the air flow inside the speaker 80R, prevent abnormal resonance such as air column resonance, improve the acoustic characteristics of the speaker 80R, and reduce the occurrence of abnormal sound.

  The sound control board 13A and the board cover 70 shown in FIG. 4 have an area that can cover a wider area than the opening 60C0 formed in the housing rear member 60C. Therefore, the opening 60C0 can be closed by screwing the sound control board 13A and the board cover 70 using the fixing screws 72A to 72C. As described above, the sound control board 13A is disposed so as to be able to close the opening 60C0 formed in the housing rear member 60C constituting the housing 60.

  The elastic member 71 is in close contact with the housing rear member 60C and the sound control board 13A, and is formed to have the same size or substantially the same size as the sound control board 13A and the board cover 70. Accordingly, it is only necessary to reliably seal the gap between the peripheral edge portion of the opening 60C0 and the sound control board 13A and prevent an illegal act such as inserting an unauthorized tool. Note that the elastic member 71 may be formed in a size such that the end portion is exposed from the substrate cover 70. This facilitates confirmation of the sealing performance in the gap between the peripheral edge of the opening 60C0 and the sound control board 13A. Alternatively, the elastic member 71 may be formed in such a size that the end portion is accommodated in the substrate cover 70. Even in this case, it is only necessary to confirm the sealing property in the gap between the peripheral portion of the opening 60C0 and the sound control board 13A by forming the substrate cover 70 using a synthetic resin that can be seen through. A groove along the shape of the substrate cover 70 may be formed in the housing rear member 60C. When the voice control board 13A and the board cover 70 are screwed using the fixing screws 72A to 72C, the elastic member 71 may be deformed and packed in the groove. Thereby, the clearance gap between the peripheral part of opening 60C0 and the audio | voice control board | substrate 13A should just be sealed reliably.

  The elastic member 71 may be bonded to one or both of the peripheral portion of the opening 60C0 and the sound control board 13A using, for example, an adhesive. When attaching the elastic member 71, after one main surface (one of the front and back surfaces) of the elastic member 71 is attached to the outer surface of the housing rear member 60C at the peripheral edge of the opening 60C0, the other main surface of the elastic member 71 is attached. (The other of the front and back surfaces) may be attached to one surface (mounting surface) of the sound control board 13A. Alternatively, after one main surface (one of the front and back surfaces) of the elastic member 71 is attached to one surface (mounting surface) of the sound control board 13A, the other main surface (the other of the front and back surfaces) of the elastic member 71 is an opening. The peripheral portion of 60C0 may be attached to the outer surface of the housing rear member 60C. Thus, the attachment order of the elastic member 71 should just be set arbitrarily.

  As shown in FIG. 5A, the substrate cover 70 is provided with recesses 70A and 70B so that the protruding portions on the solder surface of the sound control substrate 13A do not come into contact with each other. The sound control board 13A may be a single-sided mounting board on which various electrical components are mounted on the same surface. For example, in the audio control board 13A, the connector port 73A into which the connector plug coupled to the internal wiring 74 is inserted and the connector port 73B into which the connector plug coupled to the external wiring is inserted are the same as other electrical components. Mounted on the surface. By using a single-sided mounting board, soldering when mounting the connector ports 73A and 73B and other electrical components is facilitated, and the manufacturing burden of the board can be reduced. Note that the audio control board 13A is not limited to a single-sided mounting board, and may be a double-sided mounting board in which some electric components are mounted on the same surface and other electric components are mounted on the other surface. . For example, the connector port 73B into which the connector plug coupled to the external wiring is inserted may be mounted on the other surface which is the back surface of the board surface on which the connector port 73A and other electrical components are mounted.

  The sound control board 13A is formed using a synthetic resin such as glass epoxy. The sound control board 13A may be formed using a material having higher heat resistance than the housing front member 60B and the housing rear member 60C, for example. Alternatively, the audio control board 13A may be formed using a material having higher strength than, for example, the case front member 60B and the case rear member 60C. Thereby, it becomes difficult to break through the audio control board 13A using an unauthorized member, and an unauthorized act can be reliably prevented.

  In the board mounting portion of the housing rear member 60C, when the audio control board 13A and the board cover 70 are screwed using the fixing screws 72A to 72C, the connector port 73A is located inside the housing 60 (inside the housing). The partition by the casing rear member 60C is arranged so that the connector port 73B is provided outside the casing 60 (outside the casing). The connector port 73A is exposed to the inside of the casing at an opening 60C0 formed in the casing rear member 60C. The connector port 73B is exposed to the outside of the casing through an opening 60C1 formed in the casing rear member 60C. A connector plug coupled to the internal wiring 74 is inserted into the connector port 73A. The internal wiring 74 electrically connects the audio control board 13A and the speaker body 80S. A connector plug coupled to external wiring is inserted into connector port 73B. The external wiring may be a harness or the like that electrically connects the audio control board 13A and the effect control board 12. Thus, the housing rear member 60C constituting the housing 60 has an opening 60C0 that exposes the connector port 73A for internal wiring provided in the sound control board 13A to the inside of the housing, and the sound control board 13A. It is only necessary to provide an opening 60C1 that exposes the provided external wiring connector port 73B to the outside of the housing.

  The housing rear member 60C is provided with a connector attachment portion 60CF formed by bending the housing rear member 60C inward of the housing as a concave portion for inserting and removing the connector near the connector port 73B. The connector mounting portion 60CF only needs to have a size that allows, for example, a human thumb to be inserted in the peripheral portion of the connector port 73B. This facilitates the insertion / removal operation when a connector plug for external wiring is inserted into or removed from the connector port 73B.

  A screw hole that is screwed into the fixing screws 72A to 72C is formed in the board mounting portion of the housing rear member 60C. These screw holes have a hollow cylindrical shape, and the bottom surfaces of the screw holes are closed by the housing rear member 60C. As a result, the insertion of a wire or the like from the inside of the housing 60 into the screw hole formed in the board mounting portion of the housing rear member 60C is blocked by the housing rear member 60C. Even if any one of these is removed, it is possible to reliably prevent an illegal act by inserting an unauthorized member.

  When the audio control board 13A, the board cover 70, and the like are screwed at the board mounting portion of the casing rear member 60C, the fixing screws 72A to 72C are electrically insulated by the casing rear member 60C forming a screw hole. What is necessary is just to be in the state. Thus, it is only necessary to prevent the audio control board 13A from being electrically destroyed.

  In the housing rear member 60C, on the inner side of the housing, a boss 65A is provided at the front end of the groove 60CA, a boss 65B is provided at the front end of the groove 60CB, and a boss 65C is provided at the front end of the groove 60CC. A boss 65D is provided at the front end of the groove 60CD. The bosses 65A to 65D are all arranged so as to extend to the front side of the housing joint portion 60D. The boss 65A is formed with a screw hole to be screwed with the fixing screw 61A, the boss 65B is formed with a screw hole to be screwed with the fixing screw 61B, and the boss 65C is formed with a screw hole to be screwed with the fixing screw 61C. The boss 65D is formed with a screw hole to be screwed with the fixing screw 61D. At the base of the bosses 65A to 65D, the bottom surface of the screw hole having a hollow cylindrical shape is closed by the housing rear member 60C. As a result, when any of the fixing screws 61A to 61D is removed, even if a wire or the like is inserted into the screw hole, it is blocked by the housing rear member 60C. Can be prevented. The bases of the bosses 65A to 65D are fixed to the front end of the groove portion 60CA or the like. Accordingly, it is only necessary to increase the strength of the bosses 65 </ b> A to 65 </ b> D and reduce the possibility and frequency of physical destruction.

  The speaker 80 </ b> R is provided with a bass reflex duct 62 inside the housing 60. For example, the duct 62 is disposed above the speaker body 80S so that a straight line along the extending direction does not pass through the opening 60C0. For example, the duct 62 may be provided so that the extending direction is shifted in the left-right direction (X direction or -X direction) from the position of the opening 60C0. Alternatively, the duct 62 may be provided such that the extending direction is shifted in the vertical direction (Y direction or -Y direction) from the position of the opening 60C0. Alternatively, the duct 62 may be provided such that the extending direction is shifted from the position of the opening 60C0 in an oblique direction (a combination of the X direction or the −X direction and the Y direction or the −Y direction).

  The housing rear member 60 </ b> C is provided with a step for arranging the board mounting portion in a forwardly protruding state from the rear side of the duct 62. The duct 62 and the step need only be arranged so that an arbitrary straight line passing through the inside of the duct 62 does not pass through the side of the board mounting portion with respect to the step provided on the housing rear member 60C. By arranging in this way, it is only necessary to prevent an illegal act by inserting an unauthorized member into the duct 62.

  For example, the duct 62 is installed such that one end is attached to the front side of the housing front member 60B and the other end extends to the rear side of the housing joint portion 60D. As a result, even if an unauthorized member is inserted into the duct 62, it is difficult to cause the unauthorized member to reach the housing joint 60D, and an unauthorized act of opening the housing joint 60D can be reliably prevented. .

  In the housing joint 60D, for example, as shown in FIG. 7, the housing front member 60B and the housing rear member 60C form a continuous inner surface (housing inner surface) and outer surface (housing outer surface) of the housing 60. doing. Further, in the housing joint portion 60D, the joint outer surface of the housing front member 60B and the joint inner surface of the housing rear member 60C face each other. In the housing joint portion 60D, the joint inner surface of the housing front member 60B is a continuous surface formed in one surface continuous with the inner surface of the housing other than the housing joint portion 60D, and the housing rear member 60C. The joint outer surface is a continuous surface formed in one surface continuous with the housing outer surface other than the housing joint 60D. On the other hand, in the housing joint portion 60D, the joint outer surface of the housing front member 60B is formed with a gradient so that the thickness decreases from the front side toward the rear side, and the joint inner surface of the housing rear member 60C is A gradient is formed so that the thickness decreases from the rear side toward the front side. The joint portion of the housing front member 60B and the joint portion of the housing rear member 60C sandwich the elastic member 66, and the inner periphery of the joint portion of the housing rear member 60C is the outer periphery of the joint portion of the housing front member 60B. The joining portion of the housing rear member 60C covers and joins the joining portion of the housing front member 60B so as to cover. After joining, it is only necessary that the housing front member 60B and the housing rear member 60C can form the inner surface and the outer surface of the housing with no step (or a small step) in the housing joint 60D. As a result, even when an unauthorized member is inserted into the housing 60 from the front side of the speaker 80R, it becomes difficult to insert the unauthorized member into the housing joint 60D, and an illegal act of prying open the housing joint 60D. Certain prevention is possible.

  The elastic member 66 is formed, for example, in a ring shape, and can be deformed when the housing front member 60B and the housing rear member 60C are fitted together, and the housing front member 60B and the housing rear member that constitute the housing 60. What is necessary is just to form using a softer material than 60C etc. For example, the elastic member 66 may be formed using a synthetic resin such as urethane resin or a synthetic rubber such as styrene butadiene rubber, similarly to the elastic member 71. Alternatively, the elastic member 66 may be configured using a synthetic resin or a synthetic rubber different from the elastic member 71. When the housing front member 60B and the housing rear member 60C are fitted together, the elastic member 66 is formed on the joint outer surface of the housing front member 60B and the joint inner surface of the housing rear member 60C at the housing joint portion 60D. What is necessary is just to adhere. The elastic member 66 may be formed in a size that is exposed from the housing joint 60D. Thereby, the confirmation of the airtightness in the housing joint portion 60D may be facilitated. Alternatively, the elastic member 66 may be formed in such a size that the entire elastic member 66 is accommodated in the gap between the outer surface of the housing front member 60B and the inner surface of the housing rear member 60C. Even in this case, it is only necessary that the casing front member 60B and the casing rear member 60C constituting the casing 60 are configured using a synthetic resin capable of seeing through the inside so that the sealing property at the casing joint portion 60D can be confirmed. .

  The joining portion of the housing rear member 60C as shown in FIG. 7 is not limited to the joining portion that covers the joining portion of the housing front member 60B, and the joining portion of the housing front member 60B is that of the housing rear member 60C. It may be one that covers and joins the joint portion. The housing front member 60B and the housing rear member 60C are fixed by screwing the fixing screws 61A to 61D into the screw holes of the bosses 65A to 65D. Instead, for example, a locking piece is provided on one or both of the housing front member 60B and the housing rear member 60C, and the housing front member 60B and the housing rear member 60C are fixed by the locking pieces. There may be.

  Next, a configuration example of the speaker unit 84 will be described. FIG. 11 is a rear view of the speaker unit 84. FIG. 12 is an enlarged view showing the lid member attaching portion of the speaker unit 84. FIG. 13 is an enlarged view showing the inside of the lid member 84A.

  On the back surface of the speaker unit 84 shown in FIG. 11, the lid member 84 </ b> A only needs to be screwed to the board attachment portion to which the audio control board 13 </ b> C is attached using fixing screws 85 </ b> A to 85 </ b> C. The lid member 84A is formed with a protrusion 84A0 used for positioning and the like. When the fixing screws 85A to 85C are removed, the sound control board 13C is attached to the inside of the lid member 84A as shown in FIG. On the back surface of the speaker unit 84, an opening 840 that penetrates the inside of the housing of the speaker unit 84 and the outside of the housing is formed in the board mounting portion that is covered with the lid member 84 </ b> A. Inside the housing of the speaker unit 84, the third speaker 83 is disposed on one side which is the front side among the side surfaces facing the front side and the rear side, and the sound control board is provided on the other side which is the rear side. 13C is arranged.

  For example, the sound control board 13C may be screwed to the lid member 84A. A gap between the peripheral edge of the opening 840 and the sound control board 13 </ b> C is sealed with an elastic member 87 at the board mounting portion on the back surface of the speaker unit 84. The elastic member 87 is deformable when the sound control board 13C and the lid member 84A are screwed using the fixing screws 85A to 85C, and is formed using a softer material than the housing of the speaker unit 84. Just do it. For example, the elastic member 87 may be formed using a synthetic resin such as urethane resin or a synthetic rubber such as styrene butadiene rubber, like the elastic member 71 and the elastic member 66. Alternatively, the elastic member 87 may be configured using a synthetic resin, a synthetic rubber, or the like different from the elastic member 71 and the elastic member 66. When the sound control board 13 </ b> C and the lid member 84 </ b> A are screwed using the fixing screws 85 </ b> A to 85 </ b> C, one main surface (one of the front and back surfaces) of the elastic member 87 is at the periphery of the opening 840 of the speaker unit 84. The other main surface (the other of the front and back surfaces) of the elastic member 87 may be in close contact with one surface (mounting surface) of the sound control board 13C.

  The sound control board 13 </ b> C and the lid member 84 </ b> A have an area that can cover a wider area than the opening 840 formed on the back surface of the speaker unit 84. Accordingly, the opening 840 can be closed by screwing the audio control board 13C and the lid member 84A using the fixing screws 85A to 85C. Thus, the sound control board 13 </ b> C is disposed so as to be able to close the opening 840 formed in the housing of the speaker unit 84.

  The elastic member 87 is formed in the same size as or substantially the same size as the sound control board 13C when in contact with the outer surface of the housing of the speaker unit 84 and the sound control board 13C. Accordingly, it is only necessary to reliably seal a gap between the peripheral edge of the opening 840 and the sound control board 13C and prevent an illegal act by inserting an unauthorized tool. A groove along the shape of the audio control board 13C may be formed on the outer surface of the housing of the speaker unit 84. When the sound control board 13C and the lid member 84A are screwed using the fixing screws 85A to 85C, the elastic member 87 may be deformed and packed in the groove. Thereby, the clearance gap between the peripheral part of the opening part 840 and the audio | voice control board | substrate 13C should just be sealed reliably.

  The elastic member 87 may be bonded to one or both of the peripheral edge of the opening 840 and the sound control board 13C using, for example, an adhesive. In the case shown in FIG. 12, the elastic member 87 is bonded to the peripheral edge of the opening 840. When attaching the elastic member 87, after one main surface (one of the front and back surfaces) of the elastic member 87 is attached to the outer surface of the casing of the speaker unit 84 at the peripheral edge of the opening 840, the other main surface of the elastic member 87 is attached. (The other of the front and back surfaces) may be attached to one surface (mounting surface) of the sound control board 13C. Alternatively, after one main surface (one of the front and back surfaces) of the elastic member 87 is attached to one surface (mounting surface) of the sound control board 13C, the other main surface (the other of the front and back surfaces) of the elastic member 87 is an opening. It may be attached to the outer surface of the casing of the speaker unit 84 at the periphery of 840. Thus, the attachment order of the elastic member 87 should just be set arbitrarily.

  The sound control board 13C may be a single-sided mounting board on which various electrical components are mounted on the same surface. For example, in the audio control board 13C, a connector port 90T into which a connector plug 90G coupled to the internal wiring 91A is inserted is mounted on the same surface as other electrical components. The external wiring 91B only needs to be soldered directly to the sound control board 13C. Alternatively, the connector port into which the connector plug coupled to the external wiring is inserted may be mounted on the same surface as the connector port 90T and other electrical components. By using a single-sided mounting board, soldering when mounting the connector port 90T and other electrical components is facilitated, and the manufacturing burden of the board can be reduced. Note that the voice control board 13C is not limited to a single-sided mounting board, and may be a double-sided mounting board in which some electrical components are mounted on the same surface and other electrical components are mounted on the other surface. .

  The sound control board 13C is formed using a synthetic resin such as glass epoxy. The sound control board 13C may be formed using a material having higher heat resistance than the housing of the speaker unit 84, for example. Alternatively, the sound control board 13C may be formed using a material having a higher strength than the housing of the speaker unit 84, for example. Thereby, it becomes difficult to break through the sound control board 13C using an unauthorized member, and an unauthorized act can be reliably prevented.

  At the board mounting portion on the back surface of the speaker unit 84, when the audio control board 13C and the lid member 84A are screwed using the fixing screws 85A to 85C, the connector port 90T is provided inside the housing of the speaker unit 84, A partition by the casing of the speaker unit 84 is arranged so that the external wiring 91B can be drawn out of the casing of the speaker unit 84. The connector port 90T is exposed inside the housing at an opening 840 formed on the back surface of the speaker unit 84. The external wiring 91 </ b> B is drawn to the outside of the housing through an opening 841 formed on the back surface of the speaker unit 84. A connector plug 90G coupled to the internal wiring 91A is inserted into the connector port 90T. The internal wiring 91A electrically connects the audio control board 13C and the third speaker 83. The external wiring 91 </ b> B electrically connects the audio control board 13 </ b> C and the effect control board 12. As described above, in the housing of the speaker unit 84, the opening 840 for exposing the internal wiring connector port 90T provided in the audio control board 13C to the inside of the housing, and the external wiring attached to the audio control board 13C. It is only necessary to provide an opening 841 through which 91B can be pulled out of the housing.

  Screw holes 86 </ b> A to 86 </ b> C that are screwed into the fixing screws 85 </ b> A to 85 </ b> C are formed in the board mounting portion on the back surface of the speaker unit 84. These screw holes have a hollow cylindrical shape, and the bottom surfaces of the screw holes are closed by the housing of the speaker unit 84. As a result, insertion of a wire or the like into the screw holes 86A to 86C from the front side of the speaker unit 84 is prevented by the casing of the speaker unit 84, so even if any of the fixing screws 85A to 85C is removed. In addition, it is possible to reliably prevent an illegal act caused by inserting an illegal member.

  When the audio control board 13C, the lid member 84A, and the like are screwed at the board mounting portion on the back surface of the speaker unit 84, the fixing screws 85A to 85C depend on the housing of the speaker unit 84 that forms the screw holes 86A to 86C. What is necessary is just to be in the state electrically insulated. Thereby, it is only necessary to prevent the audio control board 13C from being electrically destroyed.

  The present invention is not limited to the above embodiments, and various modifications and applications are possible. For example, the pachinko gaming machine 1 does not have to include all the technical features shown in the above embodiment, and the part described in the above embodiment so as to solve at least one problem in the prior art.

More specifically, in the above embodiment, the gap between the peripheral edge of the opening 60C0 and the sound control board 13A is sealed by the elastic member 71, and the housing 60 has a front side and a rear side. As described above, the speaker main body 80S is disposed on one side which is the front side among the side surfaces facing each other, and the opening 60C0 is formed on the other side surface which is the rear side. In contrast, the gap between the peripheral edge of the opening 60C0 and the sound control board 13A is sealed by the elastic member 71, while the opening 60C is on the other side facing the one side where the speaker body 80S is disposed. It may be formed on a side surface different from the above. Alternatively, the opening 60C is formed on the other side surface opposite to the one side surface on which the speaker body 80S is disposed, while the gap between the peripheral portion of the opening 60C0 and the sound control board 13A is sealed with the elastic member 71. It does not have to be.

  The speaker 80R and the speaker unit 84 are not limited to those used as front speakers, and may be used as bottom speakers, for example.

  The control board that can close the opening 60C0 is not limited to a board on which a large number of electrical components such as the audio control board 13A are mounted. For example, the connector port 73A and the connector port 73B, and a printed wiring that electrically connects them. It may be a simple board mounted.

  The member that seals the gap between the peripheral edge of the opening 60C0 and the sound control board 13A is not limited to the elastic member 71, and a solid member such as an adhesive that cures by drying may be used. Alternatively, at the peripheral edge of the opening 60C0, the gap between the peripheral edge of the opening 60C0 and the sound control board 13A may be sealed by, for example, welding the housing rear member 60C to the sound control board 13A.

  The present invention is applicable not only to the pachinko gaming machine 1 but also to a slot machine or the like. The slot machine is an arbitrary gaming machine that performs a predetermined game such as variable display of symbols that are a plurality of types of identification information, and that can give a predetermined game value based on the game result, more specifically, The game can be started by setting a predetermined number of bets (the number of medals or the number of credits) for one game, and a variable display device that variably displays a plurality of types of identification information (designs) that can be individually identified The display result of a plurality of reels, for example, is derived and displayed, and one game is completed, and a prize is awarded according to the display result (for example, cherry prize, watermelon prize, bell prize, replay prize, BB prize, RB prize, etc.) Is a gaming machine that can be generated. In such a slot machine, the hardware resources including a game control microcomputer for performing game control and software for performing a predetermined process cooperate with each other so that the pachinko game described in the above embodiment is performed. What is necessary is just to be comprised so that all or one part of the characteristics which the machine 1 has may be provided.

  In addition, the device configuration and various operations of the gaming machine can be arbitrarily changed and modified without departing from the spirit of the present invention. In addition, the gaming machine of the present invention is not limited to a payout type gaming machine that pays out a predetermined number of gaming media as prizes based on the occurrence of winnings, and is scored based on the occurrence of winnings by enclosing gaming media It can also be applied to an enclosed game machine that gives Slot machines are not limited to those where bets are set using medals and credits as gaming values, but only slot machines that set betting numbers using gaming balls as gaming values, or only credits as gaming values.

  As described above, in the gaming machine such as the pachinko gaming machine 1 according to the present application, for example, in the speaker 80R, the opening portion 60C0 is formed in the housing rear member 60C constituting the housing 60 to which the speaker main body 80S is attached, A gap between the peripheral edge of the opening 60C0 and the sound control board 13A is sealed with a member such as an elastic member 71. Thereby, the illegal act by inserting an unauthorized tool etc. can be prevented.

  Alternatively, for example, in the speaker 80R, the housing 60 to which the speaker main body 80S is attached has the speaker main body 80S disposed on one of the side surfaces facing the front side and the rear side on the front side. The sound control board 13A is disposed on the other side surface on the rear side. Thereby, since it is not necessary to provide the insertion part etc. which let a harness pass, the illegal act by inserting an unauthorized tool etc. can be prevented.

  Since the deformable elastic member 71 is used as a member that seals the gap, the sealing performance is improved and fraud can be prevented.

  The sound control board 13A is screwed at a board mounting portion on the rear side of the housing rear member 60C, and the elastic member 71 is placed in a predetermined range corresponding to the board mounting portion of the housing rear member 60C. One surface of the casing rear member 60C to be configured is pressed against the sound control board 13A. Thereby, the sealing property in the clearance gap between the peripheral part of the opening part 60C0 and the audio | voice control board | substrate 13A improves, and it can prevent an illegal act.

  It can be visually recognized that the elastic member 71 is on the outer peripheral side of the opening 60C0. As a result, it is easy to check the sealing performance in the gap between the peripheral edge of the opening 60C0 and the sound control board 13A, thereby preventing an illegal act.
