Description

  The present invention relates to a gaming machine such as a pachinko machine.

  Conventionally, there is a pachinko machine, for example, as a representative example of a gaming machine. This pachinko machine has, for example, an outer frame that forms an outer shell of the pachinko machine and is fixed to a game island of a game hall (hall), and a left end side in front view of the outer frame with respect to the outer frame with the opening / closing axis as an opening / closing axis. An inner frame that is supported so as to be opened and closed, a game board that is attached so that a game area is positioned in an opening formed at a substantially center of the inner frame, and a left end side in front view of the inner frame as an opening / closing axis And a front door that is supported to be openable and closable with respect to the inner frame and has a viewing window for visually recognizing the game area.

  The pachinko machine has a control board for controlling the game on the back side. Specifically, the control board is accommodated in a transparent board case. The substrate case is provided with a sealing unit that is sealed by a sealing member. The sealing unit has a plurality of sealing portions that cannot be opened unless a predetermined portion is cut, and the number of times of opening can be determined by using the plurality of sealing portions individually. In other words, the number of destruction of the sealing part is the number of times of opening the substrate case, and based on the number of times of opening, the presence or absence of unauthorized opening can be confirmed, and since the substrate case can be used until all the sealing parts are destroyed, Prevention of unauthorized opening and effective use of the substrate case are attempted.

In addition, the board case containing the control board is attached to the mounting base provided on the back side of the pachinko machine. In addition to improper countermeasures by the board case sealing unit, the board case can be removed from the mounting base. In order to prevent this, the lock / unlock operation is performed on the back side of the mounting base. This makes it difficult to replace with a fake substrate case containing an illegal substrate (see, for example, Patent Document 1).

  According to the gaming machine according to the present invention, the board housing unit is sealed in a state in which the control board is housed inside, and a part of the first metal fitting is fixed inside the board housing unit. Since the first metal fitting cannot be removed from the board housing unit unless the board housing unit is unsealed or at least partly destroyed, illegal acts on the board housing unit side of the first metal fitting can be reduced. In other words, the substrate housing unit has a structure that cannot be opened unless the sealing is released, and when the sealing is released, the opening history remains (for example, the sealing portion provided in the substrate housing unit). Opening is possible by destroying the (caulking part), but it can be known from the destruction trace that it has been opened), so that unauthorized opening can be found from the opening history. In addition, in the case of a fraudulent act that destroys a portion other than the sealing portion, the unauthorized opening can be found by finding the broken portion. Therefore, since it is avoided to open the substrate housing unit with scratches or the like, it is possible to reduce an illegal act on the substrate housing unit side of the first metal fitting. In addition, since the metal second metal part is fixed to a portion covered with the fixing member on the back side of the game board, the fixing member is destroyed (particularly, the second metal part of the fixing member is covered). The second metal fitting cannot be removed from the fixing member without destroying the location of the second metal fitting, so that it is possible to reduce fraudulent acts on the fixing member side of the second metal fitting. Also, since the first metal fitting and the second metal fitting are made of metal, even if one of the metal fittings is cut to illegally remove the board housing unit and replace the whole board housing unit containing the illegal control board, the metal fitting is cut. In such a state, the illegal substrate storage unit cannot be attached, and even if it is joined by welding or adhesion, it is possible to find an exchange for an unauthorized substrate storage unit by finding the cut trace (joint trace). . Accordingly, since cutting the first metal fitting or the second metal fitting is avoided, it is possible to reduce fraudulent acts on the first metal fitting or the second metal fitting, and to prevent the board housing unit from being stolen. As a result, it is possible to provide a gaming machine with enhanced countermeasures against fraudulent acts such as theft or replacement of control boards.

  In other words, as shown in FIG. 1, the front frame set 14 has an abbreviation so that most of the game area 30a (see FIG. 2) of the game board 30 can be viewed from the outside above the upper plate unit 21 described above. A vertically long elliptical window 101 is formed. Specifically, the window 101 has a substantially vertically long elliptical shape with a hollow center, and a glass unit (not shown) is attached to the front frame set 14 so that the hollow portion is covered with a glass plate 137 having a substantially vertically long elliptical shape. It is attached to the back side. The glass unit (not shown) has a double glass structure in which two glass plates 137 are arranged close to each other in the front-rear direction. The substantially central portion of the window 101 may be linear, and the glass plate 137 may be matched to the shape. The glass plate 137 is not limited to glass, and any material may be used as long as it is a transparent plate having a predetermined strength.

  In addition, as shown in FIG. 1, the front frame set 14 is provided with various electrical decoration portions around the window portion 101 (for example, an upper location, a left location, a right location) on the front side. These lighting parts play a role of enhancing the effect of the game by changing the light emission mode such as lighting and blinking according to the change of the game state at the time of big hit or predetermined reach. For example, the left and right lighting parts with built-in LEDs and the like are respectively provided at the left and right portions of the periphery of the window 101, and the upper part (pachinko machine 10) at the periphery of the window 101. In the uppermost part), an upper illumination part having a built-in LED or the like is also provided.

  In this pachinko machine 10, the left side lighting part, the right side lighting part, and the upper side lighting part function as a jackpot lamp, and when the jackpot is lit, blinking is performed to notify that the jackpot is being hit. In addition, a corner portion of the pachinko machine 10 is provided with a prize ball lamp 105 that is lit during payout of a prize ball and an error display lamp 106 that is lit when a predetermined error occurs. In addition, a small window 107 made of a transparent resin is provided at a lower right corner of the periphery of the window 101 so that a part of the inner frame 12 surface, the game board 30 surface, and the like can be visually recognized.

Game balls are rented out. The ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. Is done. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The lending operation unit 120 may be further provided with a frequency display unit (not shown). This frequency display unit (not shown) displays the remaining amount information such as a card. It should be noted that the ball rental operation unit 120 is not necessary for a pachinko machine in which game balls are lent directly to the upper plate from a ball lending device or the like without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  As shown in FIG. 2, the game board 30 is made of a plywood having a quadrangular shape when viewed from the front, and its peripheral edge is attached in contact with the back side of the resin base (not shown) of the inner frame 12. A gaming area 30a, which is a substantially central portion on the front side of the game board 30, is visible from the front side of the inner frame 12 through the resin-based substantially elliptical window portion 101 (glass plate 137) shown in FIG. ing.

  Next, the configuration of the game board 30 will be described with reference to FIG. The game board 30 includes a general winning port 31, a variable winning device 32, first starting ports 33a and 33b (for example, operation chucker), a second starting port 34 (for example, a through gate), a variable display unit 35, and the like. Yes. These general winning port 31, variable winning device 32, first starting ports 33a and 33b (for example, operation chucker), second starting port 34 (for example, through gate), variable display unit 35, etc. Each of the through holes formed by router processing is disposed in each through hole, and is attached from the front side of the game board 30 with a wood screw or the like. A game ball enters the aforementioned general winning port 31, variable winning device 32, and first start ports 33a and 33b, and the detected balls are detected by detection switches (winning port switch, count switch, operation port switch) described later. Based on the output of the detection switch, a predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15). As described above, the first start port 33a on the upper side is provided with an operation port switch (passage detection switch), and a ball entering the first start port 33a is detected by the operation port switch. It is like that. Further, the first start port 33b on the lower side is also provided with an operation port switch (passage detection switch), and the ball entering the first start port 33b is detected by the operation port switch. . That is, in either case of entering a game ball into the first start port 33a on the upper side or entering a game ball into the first start port 33b on the lower side, it is a start prize. There is no change. The upper first start port 33a and the lower first start port 33b are configured by a single start winning device 33 as shown in FIG.

  In addition, as shown in FIG. 2, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices or the like pass through the out port 36 in a ball discharge path (not shown). You will be guided to the direction. A number of nails are planted on the game board 30 in order to appropriately disperse and adjust the falling direction of the game balls, and various members (acts) such as the windmill 37 are arranged.

  The variable display device unit 35 includes a first symbol display device 40 for variably displaying a first symbol (for example, a special symbol) as identification information, triggered by winning in the first start ports 33a and 33b, and a second start. With the passage of the mouth 34 as a trigger, the second symbol display device 41 that variably displays the second symbol (for example, a normal symbol) and the winning of the first start ports 33a and 33b as a trigger, the third symbol (for example, a decorative symbol) ) In a variable manner.

  The first symbol display device 40 includes, for example, a plurality (two in this embodiment) of two-color light emitting type LEDs (light emitting diodes) 40a and 40b, and a hold indicating the number of hold of the variable display on the LEDs 40a and 40b. And a lamp 40c. The LEDs 40a and 40b can emit light in red and blue, for example. The first symbol display device 40 generates a variable display state of the first symbol (in this embodiment, the emission color mode of each LED 40a, 40b) by alternately changing the emission color of each LED 40a, 40b, for example, When both LEDs 40a and 40b stop in a red light emitting state, a probable big hit (specific hit) is indicated, and when both LEDs 40a and 40b stop in a blue light emitting state, a normal big hit (non-specific hit) is indicated, and both LEDs 40a and 40b are mutually connected. When it stops in the light emission state of a different color, it will show off.

  In addition, as this 1st symbol display apparatus 40, you may employ | adopt the single LED of the type which can light-emit at least 3 colors or more, and by performing light emission of each color alternately, the 1st symbol is displayed. When the LED stops in the light emission state of the first color, it shows a probable big hit (specific hit), and when the LED stops in the light emission state of the second color, it usually shows a big hit (non-specific hit) When the LED stops in the light emission state of the third color, it may be indicated that the LED has come off. The first symbol display device 40 described above corresponds to the identification information fluctuation display means in the present invention.

  The second symbol display device 41 includes, for example, a display unit 41a on which “○” is drawn for the second symbol, a display unit 41b on which “x” is drawn for the second symbol, and a holding lamp 41c. When the game ball passes through the second starting port 34, for example, the display symbols (ordinary symbols) displayed by the display units 41a and 41b change, and when the change display stops at a predetermined symbol, the lower side One start port 33b is configured to be in an activated state (opened) for a predetermined time. The number of times that the game ball has passed through the second start port 34 is held up to a maximum of 4 times, and the number of times the game ball is held is lit on the hold lamp 41c. The display units 41a and 41b have LEDs (light emitting diodes) inside thereof, and are configured to be variably displayed by switching the light emission of the LEDs (or lighting of the lamps). The second symbol display device 41 described above corresponds to the normal identification information fluctuation display means in the present invention.

  The 3rd symbol display apparatus 42 is comprised, for example with the liquid crystal display device, and the display content is controlled by the display control apparatus 45 mentioned later. On the third symbol display device 42, for example, as shown in FIG. 5 described later, three decorative symbol rows L, M, and R on the left, middle, and right are displayed. Each of the decorative symbol rows L, M, R is composed of a plurality of decorative symbols, and these decorative symbols are variably displayed on the third symbol display device 42 so as to be scrolled for each of the decorative symbol rows L, M, R. It has become so. In the present embodiment, the third symbol display device 42 (liquid crystal display device) includes, for example, a large liquid crystal display of 11 inch size. The variable display device unit 35 is provided with a center frame 47 so as to surround the third symbol display device 42. The above-described third symbol display device 42 corresponds to decoration identification information (design) variation display means in the present invention, and the above-described display control device 45 corresponds to display control means in the present invention.

  As shown in FIG. 2, the variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is in an open state in which a game ball is easy to win in the case of a big win and a normal closed state. It is operated repeatedly. As described above, a state in which the variable winning device 32 is repeatedly operated in an open state and a normal closed state in the case of a big win is called a special game state (for example, a big win state). Since the ball enters (wins) and a lot of game balls are paid out for the winning, the game state is advantageous to the player.

  More specifically, when a game ball wins the first start opening 33a, 33b, the two LEDs 40a, 40b of the first symbol display device 40 are displayed in a variable manner, and the display of the LEDs 40a, 40b after the change stop is preset. The special gaming state occurs when the combination of the light emission modes is achieved. For example, in the case of a light emitting mode in which both LEDs 40a and 40b are stopped in a red light emitting state, it indicates that a special gaming state with a probable big hit (specific hit) is won, and both LEDs 40a and 40b are stopped in a blue light emitting state. In the case of the light-emitting mode, it means that the special game state of the big hit (non-specific hit) is normally won, and in the case of the light-emitting mode in which both LEDs 40a and 40b are stopped in the light-emitting states of different colors. (You have lost the special game state).

  The variable winning device 32 is configured such that the large winning opening 32a is in a predetermined open state, and the game ball is likely to win (a big hit state). Specifically, the special winning opening 32a of the variable winning device 32 is repeatedly opened a predetermined number of times (the number of rounds) with the passage of a predetermined time or a predetermined number of winnings in the open state as one round. The number of times that the game ball has passed through the first start ports 33a and 33b is held up to a maximum of 4 times, and the number of times that the game ball is held is lit and displayed by the hold lamp 40c. Note that the hold lamp 40c may be configured such that a hold display is performed on a part of the display screen of the third symbol display device 42.

  Further, as shown in FIG. 2, the game board 30 is provided with a plurality of rails 51 and 52 for guiding the game balls launched from the game ball launching device 38 (see FIG. 3) to the upper part of the game board 30. Thus, the game balls launched in accordance with the turning operation of the game ball launching handle 18 are guided to a predetermined game area 30a through a ball guide passage 49 (to be described later) of the plurality of rails 51 and 52. . The plurality of rails 51 and 52 are long metal strip members made of stainless steel, and are attached to the game board 30 in an inner and outer double. The inner rail 51 is formed in a substantially annular shape except for about 1/4 of the upper side. The outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51. In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a ball guide passage 49 is formed by a portion (the left portion toward the left) where the rails 51 and 52 are parallel to each other at a predetermined interval. . The ball guide passage 49 is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (the upper left portion in FIG. 2). This prevents a situation in which the game ball once guided from the ball guide passage 49 between the inner rail 51 and the outer rail 52 to the upper portion of the game board 30 returns to the ball guide passage 49 again. It has become. Further, in a state in which the game board 30 is attached to the inner frame 12, the outer rail 52 is located at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 2: a portion corresponding to the tip portion of the outer rail 52). Is configured such that a return rubber (not shown) provided on the inner frame 12 is positioned. Accordingly, a game ball launched at a predetermined momentum or more is bounced by hitting a return rubber (not shown). Since the outer rail 52 is made of a long metal strip made of stainless steel, the flight of the game ball can be made smoother, that is, the frictional resistance of the game ball can be reduced.

  The lower right corner of the game board 30 is a space for sticking a seal (S1 in FIG. 2) such as a certificate (for example, a serial number is written) or a plate. By sticking a sticker such as a certificate (S1 in FIG. 2) to the lower right corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

  Next, the game area 30a of the game board 30 will be described. As shown in FIG. 2, the game area 30 a is partitioned and formed into a substantially vertically long circular shape by inner peripheral portions (inner and outer rails) of the inner rail 51 and the outer rail 52. In particular, in the present embodiment, the game board 30 The game area 30a defined on the board surface is much larger than before. In the present embodiment, the distance between the uppermost point of the outer rail 52 and the lower part of the game board 30 is 445 mm (58 mm longer than the conventional product), and is from the extreme left position of the outer rail 52 to the extreme right position of the inner rail 51. The distance is 435 mm (50 mm longer than the conventional product). The distance from the extreme left position of the inner rail 51 to the extreme right position of the inner rail 51 is 418 mm.

  In the present embodiment, the game area 30a is viewed from the front of the pachinko machine 10, and the area of the guide rail that is a parallel part of the inner and outer rails 51 and 52 is excluded from the area surrounded by the inner rail 51 and the outer rail 52. As an area. Accordingly, when the game area 30 a is referred to, the guide rail portion is not included, and therefore the left limit position toward the game area 30 a is specified by the inner rail 51, not by the outer rail 52. Similarly, the right limit position toward the game area 30 a is specified by the inner rail 51. Further, the lower limit position of the game area 30 a is specified by the lower end position of the game board 30. The upper limit position of the game area 30 a is specified by the outer rail 52.

  Therefore, in the present embodiment, the width (maximum width in the left-right direction) of the game area 30a is 418 mm, and the height (maximum width in the vertical direction) of the game area 30a is 445 mm.

  Although detailed disclosure of the drawings is omitted, game balls are supplied to the game ball launcher 38 one by one from the ball outlet on the front frame set 14 side (the ball outlet leading from the most downstream portion of the upper plate 19). .

  Next, the configuration of the back surface of the pachinko machine 10 will be described. As shown in FIG. 3, the pachinko machine 10 is configured such that various control boards are arranged vertically or horizontally on the back surface (actually the back surface of the inner frame 12 and the game board 30) or stacked in front and back. Further, a game ball supply device (payout mechanism portion 352) for supplying game balls, a protective cover made of resin, and the like are attached. In this embodiment, the control board is roughly divided into two groups: a group in which some of the various control boards are mounted on one mounting base (not shown) and a group of other control boards. It is adapted to be mounted on the frame 12 or the back side of the game board 30. In this case, the main control device 261 and the sub control device 262 shown in FIG. 4 to be described later are in one group, but in detail, the main control device 261 is unitized and the sub control device is located near the main control device 261. 262 is disposed, and a payout control device 311, a launch control device 312 and a power supply device 313 shown in FIG. 4 to be described later are mounted on a mounting base (not shown) to form a unit. Here, for convenience, the former unit is referred to as “first control board unit 201”, and the latter unit is referred to as “second control board unit 202”.

  Further, since the dispensing mechanism 352 and the protective cover are also integrated as one unit, and the resin portion is generally referred to as a back pack, the unit is referred to as a “back pack unit 203” here. The detailed configuration of each unit 201 to 203 will be described later.

  As will be described later, the first control board unit 201 has a structure that cannot be normally removed once attached. However, the second control board unit 202 and the back pack unit 203 can be attached and detached without using any tools or the like. In addition to this, in addition to this, a support shaft portion is provided in a part so that it can be opened and closed with respect to the inner frame 12 or the back surface of the game board 30. This is also a device for making it possible to easily check a hidden configuration or the like even if the units 201 to 203 and other configurations are arranged one behind the other.

  In addition, on the back surface of the game board 30, a winning detection mechanism for detecting the passage of game balls such as various winning holes is provided. Specifically, a prize opening switch is provided at a position corresponding to the general prize opening 31 on the front side of the game board 30, and the variable prize winning device 32 is provided with a count switch. The count switch is a switch for counting winning balls. In addition, operation port switches are provided at positions corresponding to the first start ports 33a and 33b, respectively, and the entry of game balls into the first start ports 33a and 33b is detected by the operation port switches. A gate switch is provided at a position corresponding to the second starting port 34, and the passage of the game ball to the second starting port 34 is detected by the operating port switch. The operating port switch described above corresponds to the winning detection means in the present invention.

  The RAM 503 has a configuration in which data can be retained (backed up) by being supplied with a backup voltage from the power supply device 313 even after the pachinko machine 10 is turned off. The RAM 503 temporarily stores various data and the like. It has a memory and area.

  That is, when the power is cut off due to the occurrence of a power failure or the like, the CPU 501 of the main control device 261 executes the normal processing up to the end, so that the RAM 503 is when the power is turned off (including when a power failure occurs, and so on). It is only necessary to store and hold the contents of the counter buffer and the holding ball storage area, and the state of the pachinko machine 10 can be restored to the state before the power is turned off when the power is turned on again. Specifically, the RAM 503 has a dedicated backup area for storing values of registers, I / O, and the like for game information during normal processing when the power is turned off (including when a power failure occurs). There is no need to provide it. The N501 terminal (non-maskable interrupt terminal) of the CPU 501 is configured to receive a power failure signal S1 output from a power failure monitoring circuit 542, which will be described later, when a power failure occurs due to the occurrence of a power failure or the like. Due to the occurrence, the power failure process (NMI interrupt process) is immediately executed.

  An input / output port 505 is connected to the CPU 501 incorporating the ROM 502 and RAM 503 via a bus line 504 including an address bus and a data bus. The input / output port 505 includes a RAM erasing switch circuit 543, a payout control device 311, a firing control device 312, a sub control device 262, a first symbol display device 40, a second symbol display device 41, and other switches not shown.

The stopper claw 439 cannot be pulled out by being caught in the recess 265a, and the latching claw 439 is depressed by a part of the substrate housing unit 390 even if the posture of the plate portion 432 is changed so that the latching portion is separated from the recess 265a. It is restricted so as not to be disengaged from the H.265a, and the posture of the plate portion 432 cannot be changed, so that unauthorized destruction aimed at pulling out the plate portion 432 can be reduced.

  The present invention is not limited to the above-described embodiment, and can be modified as follows.

  (1) In the first embodiment described above, as shown in FIG. 14, the screw 433 inserted into the pinning through hole 434 regulates the movement of the plate portion 432 in the direction toward the slit portion 264. However, the plate portion 432 of the first metal fitting 430 may be screwed and fixed to the box base 265.

  That is, the plate portion 432 of the first metal fitting 430 includes a screw through hole instead of the pinning through hole 434 of the first embodiment, and the screw penetration in the plate portion 432 in a state of being inserted into the slit portion 264. It is also possible to adopt a configuration in which the plate portion 432 is fixed inside the substrate housing unit 390 by screwing the screw 433 inserted into the hole into the screw hole 266 of the box base 265.

  In this case, as shown in FIGS. 13 and 14, when the first metal fitting 430 is pulled out from the state in which the plate portion 432 is inserted into the slit portion 264 of the substrate housing unit 390, the locking claws of the plate portion 432 are engaged. 435 is hooked on the edge of the slit portion 264, and above all, a screw 433 is inserted through the screw through hole of the plate portion 432, and the plate portion 432 is fixed inside the substrate housing unit 390. ing.

  Accordingly, not only can the first metal fitting 430 be prevented from being pulled out by the locking claws 435 of the substrate housing unit 390 while the plate portion 432 of the first metal fitting 430 is inserted into the slit portion 264 of the substrate housing unit 390. Since the screw 433 is inserted into the pinning through hole 434 of the portion 432, it is possible to prevent the screw 433 from coming out of the slit portion 264. In addition, since the screw head is embedded in the pinning through hole 434 of the first metal fitting 430, an unauthorized cutting tool (for example, the purpose of cutting the screw head) is formed in the slit portion 264 of the substrate housing unit 390. In this case, even if a thin plate-like or thread-like unauthorized cutting tool or the like inserted into the slit portion 264 of the substrate housing unit 390 is inserted, the screw head only passes over, and the screw head cannot be cut. Unauthorized destruction aimed at 433 (screw for fastening the plate portion 432 of the first metal fitting 430 to the inside of the substrate housing unit) can be reduced.

  (2) In the first embodiment described above, the collective plate 410 includes the rib 417 as shown in FIG. 6, but this rib 417 reaches the location of the second metal fitting through hole 441 of the second metal fitting 440. It may be. In this case, the rib 417 makes it difficult to access the rivet 450 of the first metal fitting 430 and the second metal fitting 440. In addition, the collective plate 410 can be retrofitted so that the standing portion 443 of the second metal fitting 440 is inserted into the notch portion 415.

  (3) In the first embodiment described above, the collective plate 410 is provided with a notch 415 as shown in FIG. 6, but an insertion hole is provided instead of the notch 415, and a second is provided in the insertion hole. You may employ | adopt the structure which inserts the standing part 443 of the metal fitting 440. FIG. In this case, unless the insertion hole portion of the collective plate 410 is broken, the collective plate 410 cannot be removed unless the collective plate 410 is also removed from the game board 30, which is excellent in anti-fraud measures.

  (4) In each of the above-described embodiments, the board box 263 itself can be opened to the game board 30 by the one-side opening mechanism 420, but the mounting base (mounting base) to which the board box 263 is attached is one-sided. A configuration in which the mechanism 420 can be opened to the game board 30 by a mechanism 420 may be adopted.

  Examples of such a configuration include the following. That is, the board housing unit includes a board box that houses the main control board 261a and a mounting base to which the board box is attached. The board box is a first breaking screw that breaks at a predetermined position when turned in the loosening direction. Or, it can be fixed to the mounting base with a second breaking screw that is turned in the tightening direction to break the screw head, or a one-way screw that cannot be turned in the loosening direction or is difficult to turn. The base is supported on the back side of the game board 30 so as to be freely openable to the game board 30. The board box includes a box base 265 and a box cover 267, and the box base 265 and the box cover 267 are combined. In this state, the main control board 261a is accommodated in the internal space. Configuration that includes a sealing unit 269 to seal the box base 265 and the box cover 267 (sealing) and the like.

  In the case of the single-opening mechanism 420 that supports such a configuration, that is, the mounting base to which the board box 263 containing the main control board 261a is attached is supported on the back side of the game board 30 so as to be freely openable to the game board 30. Even so, the same effects as those of the first embodiment are obtained.

  (5) In the above-described embodiment, as shown in FIG. 15, the box base 265 and the box cover 267 are sealed by the sealing unit 269, but the above-described breaking screw (first breaking screw or second breaking screw). Alternatively, sealing may be performed using one-way screws, or these breaking screws and one-way screws may be employed together with the sealing unit 269.

  (6) In each of the above-described embodiments, an example in which the main control board 261a is adopted as the control board has been described, but a control board other than the main control board 261a (for example, the payout control board 311a, the sub control board 262a, etc.) Various control boards) may be employed.

  (7) In the embodiment described above, the collective plate 410 is employed as the fixing member, but a member other than the collective plate 410 and fixed to the game board 30 may be employed.

  (8) In the above-described embodiment, the rivet 450 is employed as the connecting (fastening) member, but a fastener or a connecting tool other than the rivet may be employed. In the above-described embodiment, the tip of the rivet 450 is deformed, but a hole may be formed at the tip of the rivet 450, and a stop pin may be inserted into the hole to form a connecting (fastening) member. In addition, an insertion portion is formed at a predetermined location of the first metal fitting 430, the insertion portion of the first metal fitting 430 is inserted into an insertion hole formed in the second metal fitting 440, and the predetermined location of the insertion portion is deformed in that state. The first metal fitting 430 and the second metal fitting 440 may be pivotally connected (fastened), or an insertion portion may be formed in the second metal fitting 440 and an insertion hole formed in the first metal fitting 430.

  (9) The present invention may be implemented in various (for example, first type, third type, etc.) gaming machines, or may be implemented in a pachinko machine of a type different from the above example. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Moreover, after a jackpot symbol is displayed, it may be implemented as a pachinko machine that enters a special game state on the condition that a ball is won in a predetermined area. Moreover, you may implement as a pachinko machine which will be in a special game state when a ball enters a predetermined winning opening. Further, in addition to pachinko machines, various game machines such as an arrangement ball type pachinko machine, a sparrow ball, a game machine in which a so-called pachinko machine and a slot machine are integrated may be used.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are fused, a variable display means for displaying a fixed symbol after displaying a variable symbol row consisting of a plurality of symbols is provided, and a handle for launching a ball is provided. What is not provided.
