Hereinafter, an embodiment when applied to a rotating cylinder type gaming machine, which is a kind of gaming machine, specifically, a slot machine, will be described in detail with reference to the drawings. 1 is a front view of the slot machine 10, FIG. 2 is a perspective view of the slot machine 10, FIG. 3 is a rear view of the front door 12, and FIG. 4 is a front view of the housing 11 with the front door 12 removed.

As shown in FIGS. 1 to 4, the slot machine 10 includes a housing 11 that forms an outer shell thereof. The housing 11 is composed of a top plate 11a, a bottom plate 11b, a back plate 11c, a left side plate 11d and a right side plate 11e formed in the shape of a wooden plate, and the adjacent plates 11a to 11e are fixed by fixing means such as adhesion. As a result, it is formed in a box shape with the front surface open as a whole. In addition to being made of wooden panels, each of the plates 11a to 11e may be made of a synthetic resin panel or a metal panel, or may be made of a synthetic resin material or a metal material to form an integral box. You may. The housing 11 configured as described above is attached by, for example, nailing a so-called island facility when it is installed in the game hall.

A front door 12 is provided on the front side of the housing 11. The front door 12 is rotatably supported by the left side plate 11d of the housing 11 by a pair of upper and lower hinge mechanisms 25a and 25b.

Further, the front door 12 is locked by the engagement between the locking device 600 provided on the back side thereof and the support metal fitting 800 provided on the housing 11 side. In the closed state of the front door 12, only the cylinder lock 700 of the locking device 600 is exposed on the front side of the front door 12. Then, by inserting the key into the cylinder lock 700 and rotating it clockwise when viewed from the front side of the slot machine 10, the locking device 600 and the support metal fitting 800 are unlocked, and the front door 12 is opened. Opening is allowed.

A game panel 30 for notifying the player of the game state is provided near the center of the front door 12. The game panel 30 is formed so that three vertically long display windows 31L, 31M, and 31R are arranged side by side. The display windows 31L, 31M, 31R are made of a transparent or translucent material, and the inside of the slot machine 10 can be visually recognized through the display windows 31L, 31M, 31R. The display windows 31L, 31M, and 31R may be combined into one to form a common display window.

As shown in FIG. 4, the inside of the housing 11 is divided into upper and lower parts by a partition plate 40, and a reel unit 41 constituting a variable display means is attached to the upper part of the partition plate 40.

The reel unit 41 includes a left reel 42L, a middle reel 42M, and a right reel 42R as rotating bodies formed in a cylindrical shape (annular shape), respectively. Each reel 42L, 42M, 42R is rotatably supported so that its central axis is the rotation axis of the reel. The rotation axes of the reels 42L, 42M, 42R are arranged on the same axis extending in the substantially horizontal direction, and the reels 42L, 42M, 42R correspond one-to-one with the display windows 31L, 31M, 31R. .. Therefore, a part of the surface of each reel 42L, 42M, 42R is visible through the corresponding display windows 31L, 31M, 31R, respectively. A belt-shaped belt is wound around the outer peripheral surfaces of the reels 42L, 42M, and 42R, and a large number of symbols as identification information are printed on the outer peripheral surface of the belt at equal intervals. Then, when the reels 42L, 42M, 42R rotate in the forward direction, the surfaces of the reels 42L, 42M, 42R are projected as if they are moving from top to bottom through the display windows 31L, 31M, 31R.

Each of these reels 42L, 42M, 42R is connected to stepping motors 61L, 61M, 61R (see FIG. 6) as driving means, and each reel 42L is driven by driving each stepping motor 61L, 61M, 61R. , 42M, 42R can be rotationally driven individually, that is, independently of each other. Then, as the drive shafts of the stepping motors 61L, 61M, 61R rotate, the reels 42L, 42M, 42R rotate around the drive shafts so as to rotate.

Further, reel index sensors 55L, 55M, 55R (see FIG. 6) are installed in the reel unit 41. In the present embodiment, as the reel index sensors 55L, 55M, 55R, a transmissive photo sensor in which a light emitting element and a light receiving element are held at predetermined intervals is adopted. Then, each reel index sensor 55L, 55M, 55R detects that a sensor cut van (not shown) passes between both elements every time each reel 42L, 42M, 42R makes almost one round, and each time, the main control described later is performed. A detection signal is output to the device 131. Based on this detection signal, the main control device 131 can confirm and correct the rotation position of each reel 42L, 42M, 42R approximately every one round.

For example, in the present embodiment, the stepping motors 61L, 61M, 61R are set to rotate once by giving a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter). That is, each reel 42L, 42M, 42R is configured to rotate by a rotation amount corresponding to the number of drive signals, such that each reel 42L, 42M, 42R changes by 5 ° with a 7-pulse drive signal. There is. Further, the rotation position of the stepping motors 61L, 61M, 61R, that is, the rotation position of each reel 42L, 42M, 42R is controlled by this drive signal.

On each of the belts of the reels 42L, 42M, and 42R described above, a plurality of symbols, specifically 21 symbols, are drawn in the long side direction (circumferential direction) thereof. Therefore, it takes 24 pulses (= 504 pulses ÷ 21 symbols) to switch from one symbol to the next at a predetermined position. Then, based on the number of pulses from the time when the rotation position of each reel 42L, 42M, 42R is detected, it is possible to recognize which symbol is visible from each display window 31L, 31M, 31R, or arbitrarily. It is possible to control the design so that it can be visually recognized from the display windows 31L, 31M, and 31R.

Of the symbols attached to the reels 42L, 42M, 42R, the number of symbols that can be visually recognized as a whole through the display windows 31L, 31M, 31R is mainly determined by the length of the display windows 31L, 31M, 31R in the vertical direction. Limited to a predetermined number. In this embodiment, there are three reels each. Therefore, when all the reels 42L, 42M, and 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

Here, the symbols attached to the reels 42L, 42M, and 42R will be described. FIG. 5 shows a design arrangement drawn on a belt wound around each of the left reel 42L, the middle reel 42M, and the right reel 42R. As shown in the figure, 21 symbols are provided in a row on each reel 42L, 42M, 42R. Numbers 1 to 21 are assigned to each reel 42L, 42M, 42R, but this is for convenience of explanation and is not actually attached to the reels 42L, 42M, 42R. .. However, in the following description, the number will be used.

As the symbols, there are a "red 7" symbol (for example, the 20th left belt) and a "white 7" symbol (for example, the 19th left belt) as the first special symbol for shifting to the big bonus game. .. In addition, there is a "BAR" symbol (for example, the 14th left belt) as a second special symbol for shifting to the regular bonus game. In addition, there is a "replay" symbol (for example, the eleventh left belt) as a third special symbol for shifting to the replay game. In addition, the "watermelon" symbol (for example, the 9th left belt), the "bell" symbol (for example, the 8th left belt), and the "cherry" symbol (for example, the left) as the small winning combination symbols for which the small winning combination is paid out. There is a fourth belt). As shown in FIG. 5, in the belts wound around the reels 42L, 42M, and 42R, the number and arrangement order of various symbols are completely different.

The game panel 30 is provided with a total of five combination lines, three in parallel in the horizontal direction and two in the diagonal direction so as to connect the display windows 31L, 31M, and 31R. Of course, the maximum number of combination lines may be 6 or more, less than 5, and the maximum number of combination lines may be changed according to a predetermined condition. Effective line display units 32, 33, and 34 are provided on the left side when viewed from the front of the display windows 31L, 31M, and 31R groups corresponding to each of these combination lines. The first effective line display unit 32 is notified by lighting or the like when the central horizontal line (center line) of the combination lines is activated. The second effective line display unit 33 is notified by lighting or the like when the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated. The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (a downward-sloping line and an upward-sloping line) of the combination lines are enabled. Then, when the symbols stop at the activated combination line, that is, the valid line in a predetermined combination, a prize is won, and a predetermined medal payout process, a transfer process to a specific game, and the like are executed.

Here, the number of payouts for each symbol in the case of winning a prize will be described. Regarding small role symbols, if the "watermelon" symbol is aligned with the left, middle, and right on the effective line, 15 medals will be paid out, and if the "bell" symbol is aligned with the left, middle, and right on the effective line, Eight medals are paid out, and two medals are paid out when the "cherry" symbol on the left reel 42L stops on the effective line. That is, the "cherry" symbols on the middle reel 42M and the right reel 42R have nothing to do with medal payout. In addition, since the medal is paid out regardless of the combination with other symbols only for the "cherry" symbol, "specifically, the upper or lower row" is set at the position where the plurality of effective lines of the left reel 42L overlap. When the "cherry" symbol is stopped, medals are paid out by multiplying the number of overlapping effective lines, and as a result, four medals are paid out in the present embodiment.

Regarding other symbols, when the "red 7" symbol or "white 7" symbol, which is a combination of the first special symbol (big bonus symbol), is aligned with the left, middle, and right on the effective line with the same symbol. 15 medals will be paid out, and 15 medals will be paid out even if the "BAR" symbol, which is a combination of the second special symbol (regular bonus symbol), is aligned with the left, middle, and right on the effective line. In the present embodiment, for example, the "red 7" symbol and the "cherry" symbol may be established at the same time, and in such a case, 15 medals are paid out. This is because the maximum number of medals to be paid out at one time is set to 15.

Furthermore, if the "replay" symbol, which is a combination of the third special symbols, is aligned with the left, middle, and right on the effective line, the medal will not be paid out. In other cases, that is, if the "cherry" symbol on the left reel 42L does not stop on the effective line and the same symbols as left, middle, and right are not aligned on the effective line, no medal is paid out.

Here, the bonus game in this embodiment will be described. The regular bonus (hereinafter referred to as "RB") game even consists of 12 JAC games. The JAC game is a game in which only one bet is allowed, and the probability that the JAC symbols (here, the replay symbols are substituted) are aligned on the effective line, that is, the establishment of the JAC symbols is very high. When the JAC symbol is established in the JAC game, the maximum number of medals (15 in this case) will be paid out. Then, when the JAC symbol is established 8 times, the RB game ends even before the JAC game reaches 12 times. On the other hand, the big bonus (hereinafter referred to as "BB") game is composed of 30 small role games and 3 JAC ins. A small role game is a game in which a small role is won with a high probability ("bell" symbols are aligned on the effective line), and JAC in means entering 12 JAC games, and a small role game. JAC in is established when the JAC symbols are aligned on the effective line. The JAC game is the same as the case of the RB game. Also, when the third JAC in is finished, the BB game is finished even before the small role game reaches 30 times, and when the 30 small role games are finished, before the JAC in reaches 3 times. Even if there is, the BB game ends. The form of the bonus game is not limited to the above form, and may be a different form.

By the way, an operation area 51 is provided below the game panel 30. The operation area 51 has a flat panel portion 51a extending from the lower end of the game panel 30 toward the front side, and a vertical wall portion 51b hanging downward from the front end of the flat panel portion 51a. ing.

On the left side of the vertical wall portion 51b, a start lever 71 that is operated to start rotating the reels 42L, 42M, and 42R all at once (not necessarily at the same time) is provided. The start lever 71 constitutes a starting operation means operated to start rotating the reels 42L, 42M, 42R, that is, to start the variable display. The start lever 71 is a lever that is pushed and operated by the player when the player starts the game, and automatically returns to the original position after the hand is released. If the start lever 71 is operated while the medal is being inserted, the reels 42L, 42M, and 42R start rotating all at once.

On the right side of the start lever 71, button-shaped stop switches 72, 73, 74 that are operated to individually stop the rotating reels 42L, 42M, 42R are provided. The stop switches 72, 73, and 74 are arranged substantially directly below the display windows 31L, 31M, and 31R corresponding to the reels 42L, 42M, and 42R to be stopped. The stop switches 72, 73, 74 constitute a stop operation means operated to stop the variable display based on the rotation of the reels 42L, 42M, 42R. Each of the stop switches 72, 73, 74 is in a state where it can be stopped after a predetermined time has elapsed from the start of rotation of the left reel 42L, and during such a state, a lamp (not shown) is lit and displayed to stop. It is notified that the operation is possible, and it is turned off when the rotation stops.

A medal insertion slot 75 for inserting medals is provided on the right side of the flat panel portion 51a of the operation area 51. The medals inserted from the medal insertion slot 75 are guided to either the storage passage 81 or the discharge passage 82 by the selector 84 as the passage switching means provided on the back surface of the front door 12. That is, the selector 84 is provided with a medal passage switching solenoid 83 (see FIG. 6) so that the medal passage switching solenoid 83 can be switched to the discharge passage 82 side when not excited and to the storage passage 81 side when excited. It has become. The medal guided to the storage passage 81 is guided to the hopper device 91 housed inside the housing 11. On the other hand, the medal guided to the discharge passage 82 is guided to the medal tray 18 from the medal discharge port 17 provided in the lower front portion of the front door 12, and is returned to the player.

The hopper device 91 as a payout means for giving medals to the player is composed of a storage tank 92 for storing medals and a payout device 93 for paying out medals to the player. The payout device 93 discharges medals to the opening 94 provided in the center right portion of the discharge passage 82 by rotating a rotating plate for paying medals (not shown), and medals to the medal tray 18 through the discharge passage 82. Is to be paid out. Further, on the right side of the hopper device 91, a spare tank 95 is provided to prevent a predetermined amount or more of medals from being stored in the storage tank 92. Inside the storage tank 92 of the hopper device 91, a guide plate 96 for discharging medals from the storage tank 92 to the spare tank 95 is provided. Therefore, when medals are stored above the height at which the guide plate 96 is provided, such medals are stored in the spare tank 95.

A button-shaped return switch 76 is provided below the medal insertion slot 75. The return switch 76 is a switch that is pressed when a medal inserted into the medal insertion slot 75 is jammed in the selector 84, and when this switch is pressed, the selector 84 is mechanically interlocked to operate, and the selector 84 is operated. The medals packed in the 84 are returned from the medal outlet 17.

A first credit insertion switch 77 is provided on the left side of the flat panel portion 51a of the operation area 51. The first credit insertion switch 77 is for inserting three credited virtual medals at a time. Further, on the left side of the first credit insertion switch 77, a second credit insertion switch 78 is provided as a button-shaped switch smaller than the switch 77. The second credit insertion switch 78 is for inserting one credited virtual medal at a time.

The first credit insertion switch 77 is a so-called max bet button in which the maximum medal bet is placed in one operation. Therefore, since the first credit insertion switch 77 is operated by the player relatively frequently, the operation buttons such as the stop switches 72 to 74 are formed larger than other switches, making it easier for the player to operate. ing.

By the way, a button-shaped changeover switch 80 is provided on the left side of the start lever 71. The changeover switch 80 is configured to be a toggle type that turns on when pressed once, turns off when pressed again, and switches on and off each time a subsequent pressing operation is performed. The changeover switch 80 is operated to change the handling format of the inserted medals inserted into the medal insertion slot 75 in excess of the required amount and the acquired medals returned to the player as a result of a predetermined game.

When the changeover switch 80 is on, the "credit mode" is set so that the surplus inserted medals and the medals won at the time of winning are stored and stored as credit medals until the predetermined maximum value (for example, 50 medals) is reached. ". When the changeover switch 80 is in the off state, the "direct mode" is set so that the surplus inserted medals and the winning medals at the time of winning are paid out as actual medals. If there is a credit medal when the mode is switched from the credit mode to the direct mode, the credit medal for that amount is paid out as an actual medal. In this way, the player can execute the game in a format according to his / her preference by switching between the credit mode and the direct mode. The changeover switch 80 constitutes a changeover operation means for switching the handling type. Further, paying attention to the function of paying out the credited virtual medal as an actual medal, it can be said that the changeover switch 80 constitutes a settlement operation means for actually paying out the stored and stored game value. In addition to being configured to switch between "credit mode" and "direct mode" by operating the changeover switch 80, the virtual medal stored and stored is paid out when the changeover switch 80 is operated by always setting the "credit mode". It may function as a payment switch only.

Various operation switches such as the start lever 71, stop switches 72 to 74, credit input switches 77 and 78, and changeover switch 80 are unitized by housing various members such as operation buttons and sensors for detecting their operations in a case. It is attached to the operation area 51 in the state. Each of these operation switches is connected to an operation relay board 112 described later via a connection cable, and the operation relay board 112 is connected to a main control device 131 described later via a connection cable. However, each of the above operation switches in the present embodiment is connected to the connection cable by a connector in the case, and the connection cable cannot be removed unless the case is opened.

Below the display windows 31L, 31M, 31R of the game panel 30, there is a remaining number display unit 35 that displays the number of medals that are activated and stored in the credit mode, and in special game states such as big bonuses and regular bonuses. For example, a game number display unit 36 for displaying the number of remaining games and the like and an acquired number display unit 37 for displaying the number of acquired medals are provided. These display units 35 to 37 are composed of a 7-segment display, but it is naturally possible to replace them with a liquid crystal display or the like.

Here, the procedure for betting medals will be described. In both the direct mode and the credit mode, when a medal is inserted from the medal insertion slot 75 at the start of the game, a bet is placed.

That is, when the first medal is inserted into the medal insertion slot 75, the first effective line display unit 32 lights up, and the corresponding central line becomes the effective line, and the second medal is the medal insertion slot. When it is inserted into 75, the second effective line display unit 33 lights up, and a total of three combination lines including the corresponding upper line and lower line become effective lines, and the third medal is a medal. When it is inserted into the insertion port 75, the third effective line display unit 34 is further lit, and all five combination lines including a pair of diagonal lines corresponding to the third effective line display unit 34 become effective lines.

Further, when four or more medals are inserted into the medal insertion slot 75, the surplus medals exceeding three are switched to the discharge passage 82 by the selector 84 if the mode at that time is the direct mode. It is returned from the discharge port 17 to the medal tray 18. On the other hand, in the credit mode, the number of saved cards is displayed inside the slot machine and the remaining number display unit 35 displays the number of saved cards. An upper limit is set for the number of stored medals (for example, 50), and when more medals are inserted, the medals are returned from the medal ejection port 17 to the medal tray 18.

In addition, when the game is played in the credit mode and the number of stored sheets is displayed on the remaining number display unit 35, the virtual medal is also displayed when any of the first and second credit insertion switches 77 and 78 is pressed. Is put in and becomes a bet.

For example, when the second credit insertion switch 78 is pressed, one numerical value displayed on the remaining number display unit 35 is decremented as if one virtual medal has been inserted, and the first effective line display unit is displayed. 32 lights up and the center line becomes an effective line. Further, when the first credit insertion switch 77 is pressed, three numerical values displayed on the remaining number display unit 35 are decremented as if three virtual medals have been inserted, and all the effective line display units are displayed. 32 to 34 are lit and a total of 5 combination lines become effective lines.

When the virtual medals to be inserted when any of the first and second credit insertion switches 77 and 78 are pressed are not stored, for example, when the display of the remaining number display unit 35 is 2, the first credit is inserted. When the insertion switch 77 is pressed, all the numerical values of the remaining number display unit 35 are decremented to 0, and only the virtual medals that can be inserted are bet.

By the way, on the upper part of the front door 12, there is an upper lamp 13 that lights up or blinks as the game progresses, various sound effects are sounded as the game progresses, and the game state is notified to the player. A pair of left and right speakers 14A and an auxiliary display unit 15 for giving various information to the player are provided. In the present embodiment, the auxiliary display unit 15 is configured by a liquid crystal display for the purpose of diversifying the display contents and increasing the weight of the display effect, but even if another display such as a dot matrix display is used. Good. The auxiliary display unit 15 is for executing various display effects as the game progresses, and it can be considered that the game by each reel 42L, 42M, 42R is due to the main display unit. Therefore, in the present embodiment, the auxiliary display unit 15 is used. It is called an auxiliary display unit 15. On the back surface of the auxiliary display unit 15, an upper lamp 13, a speaker 14A, and a sub control device 111 for driving the auxiliary display unit 15 are provided. The positions and numbers of the upper lamp 13 and the speaker 14A are not particularly limited to those described above.

The sub control device 111 is a control device for driving the upper lamp 13, the speakers 14A and 14B, and the auxiliary display unit 15, and includes a substrate including a CPU, ROM, RAM, and the like for driving these.

The sub control device 111 is configured to independently drive and control the upper lamp 13, the speakers 14A and 14B, and the auxiliary display unit 15 based on a signal from the main control device 131 described later. By executing the indirect control of voice, lamp, display, etc. related to the game by the sub control device 111, the burden on the main control device 131 can be reduced. That is, the sub-control device 111 corresponds to a sub-board that executes auxiliary control in relation to the main control device 131, which is the main board that controls and manages the game. Of course, the sub-control device 111 may control the various display units 32 to 37.

The sub control device 111 is configured such that the substrate (sub substrate) 200 is housed in a substrate box 201 as an encapsulating member made of a transparent resin material or the like (see FIG. 9). The substrate box 201 includes a box base 202 having a substantially rectangular parallelepiped shape, and a box cover 203 that covers an opening of the box base 202. The substrate box 201 has a sealing structure (so-called caulking structure), whereby the box base 202 and the box cover 203 are unopenably connected to each other.

Any configuration can be applied to the sealing structure as long as the box base 202 and the box cover 203 are connected so as not to be opened. However, in the present embodiment, as shown in FIG. 7, a plurality of connecting portions 205 are connected. By inserting a caulking member such as a breaking screw or a one-way screw into the hole of the connecting portion 205, the box base 202 and the box cover 203 are connected so as not to be opened.

The sealing process of the substrate box 201 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if the unauthorized opening is performed, and once opened. Even after this, it is possible to reopen and seal the seal. That is, the sealing process is performed by inserting the caulking member into the hole of at least one of the plurality of connecting portions 205. Then, when the substrate box 201 is opened due to a defect in the accommodated substrate 200 or the like, the connection between the connecting portion 205 into which the caulking member is inserted and the other connecting portion 205 is cut off. After that, when the sealing process is performed again, the caulking member is inserted into the hole of the other connecting portion 205. If the history of the opening of the board box 201 is left in the board box 201, it is possible to easily discover that the illegal opening has been performed by looking at the board box 201.

However, as will be described later, the board 200 is provided with terminal portions 401 and the like for connecting the connectors of various connection cables, and the board box 201 is provided with connector openings 405 and the like corresponding to these terminal portions 401 and the like. Is provided (see FIG. 7). As a result, the terminal portion 401 and the like are exposed from the board box 201.

Above the medal tray 18, a lower plate 16 on which a model name, characters related to the game, and the like are displayed is mounted. Further, on the left side of the medal tray 18, an ashtray 19 that can be inverted is provided on the lower front side. Further, in the back of the medal tray 18, a pair of left and right speakers 14B similar to the speaker 14A are provided.

A power supply box 121 is provided on the left side of the hopper device 91 inside the housing 11. The power supply box 121 includes a power supply switch 122, a setting key insertion hole 124, and the like. The power switch 122 is a start switch for supplying power to each unit including the main control device 131. The setting key insertion hole 124 is for a hole manager or the like to adjust the medal output. That is, the hall manager or the like can change the setting state (winning probability setting process) of the slot machine 10 from "setting 1" to "setting 6" by inserting the setting key into the setting key insertion hole 124 and operating the slot machine 10. It has become.

Above the reel unit 41, the main control device 131 is attached to the back plate 11c of the housing 11. The main control device 131 constitutes a main board that centrally manages the game, and as will be described later, a CPU that controls the main control, a ROM that stores the game program, and necessary data according to the progress of the game are temporarily stored. It is equipped with a board (main board) including a RAM for storing data, a port for communicating with various devices, a clock circuit used for time counting and synchronization, etc., and is similar to the sub-control device 111. This substrate is housed in a substrate box having a sealed structure.

Here, the characteristic configuration of the present embodiment will be described. In the present embodiment, the main control device 131, the sub control device 111, and the like have a characteristic configuration related to a portion to which the connector of the connection cable is connected. Hereinafter, the sub-control device 111 will be described in detail as an example.

The substrate 200 of the sub-control device 111 is provided with terminal portions 401, 402, 403, and 404 electrically connected to a CPU or the like via a wiring pattern (see FIG. 7).

The connector of the connection cable for receiving the control signal from the main control device 131 is connected to the terminal portion 401, and the connector of the connection cable for outputting the control signal to the upper lamp 13 is connected to the terminal portion 402. , The connector of the connection cable for outputting the control signal to the speakers 14A and 14B is connected to the terminal portion 403, and the connector of the connection cable for outputting the control signal to the auxiliary display unit 15 is connected to the terminal portion 404. Connected (see Figure 9).

On the other hand, in the recess 203a of the board box 201 (box cover 203), a plurality of connector openings (hereinafter, simply referred to as openings) 405 to 408 are provided corresponding to the terminal portions 401 to 404 (hereinafter, simply referred to as openings). (See FIG. 7). Then, the terminal portions 401 to 404 protrude from the openings 405 to 408, respectively, and are exposed to the outside of the substrate box 201.

Further, a connector cover 411 as a covering member made of a transparent resin material is attached to the board box 201 so as to cover these terminal portions 401 to 404 (connectors of connection cables connected to the terminal portions 401 to 404). (See Fig. 9).

8 (a) and 8 (b) are a side view and a bottom view showing the connector cover 411, respectively. The connector cover 411 has a substantially rectangular cover wall portion that covers the surface of the connection cable on the disconnection direction side. 412, a top wall portion 413 projecting in a direction orthogonal to the cover wall portion 412, and a pair of arm portions 414 extending integrally to both ends of the ceiling wall 413 and projecting in a direction orthogonal to the cover wall portion 412. A locking claw 415 that is integrally provided at the tip of the arm portion 414 and projects downward, a support wall portion 416 that extends from the lower side of the cover wall portion 412 in the same direction as the arm portion 414, and the support wall. It is provided with a side wall portion 417 that connects the portions 416 and the arm portions 414, and a protrusion 418 that protrudes from the central portion in the longitudinal direction of the lower side of the cover wall portion 412 in the direction opposite to the support wall portion 416. ~ 418 are integrally molded.

The connector cover 411 is attached to the board box 201 from the front side of the box cover 203 in the orientation shown in FIG.

More specifically, the connector cover 411 moves the arm portion 414 along the side surface of the substrate box 201 until the tips of the side wall portion 417 and the support wall portion 416 come into contact with the recess 203a of the substrate box 201. As a result, the locking claw 415 is caught on the back side (box base 202) of the substrate box 201 and is in a locked state (see FIG. 9).

As shown in FIG. 9, when the connector cover 411 is attached, the distance between the connector CN of the connection cable CC and the cover wall portion 412 is shorter than the distance (insertion amount) required for removing the connector CN. Become. Further, the tilting of the connector cover 411 is restricted by the surface contact of the support wall portion 416 with the stepped portion 203b of the box cover 203. Further, the cover wall portion 412 of the connector cover 411 and the front wall 203c of the box cover 203 adjacent thereto are substantially flush with each other.

At the same time, in the mounted state of the connector cover 411, an opening 419 is formed between the top wall portion 413 and the board box 201, and the cable CA of the connection cable CC is derived from the opening 419. Due to the presence of the opening 419, the connection state of the connection cable CC is not hindered, and the adverse effect on the cable CA is suppressed.

Further, a protrusion 204 is provided on the edge of the front wall 203c of the box cover 203 that is flush with the cover wall 412 of the connector cover 411, corresponding to the protrusion 418 of the connector cover 411. The protrusion 418 corresponds to the first protrusion in the present embodiment, and the protrusion 204 corresponds to the second protrusion.

The protrusion 418 and the protrusion 204 in the present embodiment are formed so that their protrusion length, width, thickness, and the like are substantially the same. When the connector cover 411 is attached, the protrusions 418 and 204 overlap each other in the thickness direction (left-right direction in FIG. 9) and are in surface contact with each other.

Further, through holes 418a and 204a penetrating in the thickness direction thereof are formed at the roots of the protrusions 418 and 204. Instead of the through holes 418a and 204a, it may be a recess into which the locking claws 513a and 514a of the locking pieces 513 and 514 described later enter.

Then, as shown in FIG. 9, after the connector cover 411 is attached, the sealing cap 500 is attached to the protrusions 418 and 204 so as to cover the protrusion 418 of the connector cover 411 and the protrusion 204 of the box cover 203. Is attached. That is, the sealing cap 500 is attached so as to straddle both the connector cover 411 and the box cover 203. The sealing cap 500 corresponds to the lid member in this embodiment.

Here, the sealing cap 500 will be described in detail with reference to FIGS. 10 to 15. 10 to 14 are a perspective view, a plan view, a front view, a rear view, and a side view showing the sealing cap 500, respectively. FIG. 15 is a cross-sectional view taken along the line KK of FIG.

The sealing cap 500 is integrally formed entirely of a resin material such as polycarbonate.

The sealing cap 500 includes a substantially box-shaped main body 501 having an opening on the front side. The main body portion 501 is composed of an upper wall portion 502, a lower wall portion 503, a left wall portion 504, a right wall portion 505, and a back wall portion 506. These wall portions 502 to 506 form a peripheral wall portion in the present embodiment.

In the left wall portion 504 and the right wall portion 505, bulging portions 507 and 508 that bulge outward in a stepped shape in the central portion in the vertical direction are formed along the front-rear direction, and inside the bulging portions 507 and 508, respectively. Grooves 509 and 510 are formed along the front-rear direction. The distance X1 between the groove portions 509 and 510 is set to a size corresponding to the width of the protrusions 418 and 204. Further, the vertical width X2 of the groove portions 509 and 510 is set to a size corresponding to the thickness of the protrusion portions 418 and 204. The groove portions 509 and 510 correspond to the guide grooves in the present embodiment.

The back wall portion 506 is formed with a rectangular opening 511 that opens in the entire left-right direction in a range corresponding to the upper and lower sections of the grooves 509 and 510.

Inside the main body 501, a pair of locking pieces 513, 514 extending forward in the shape of a tongue piece from the upper and lower sides of the opening 511 are provided. Locking claws 513a and 514a are projected from the tips of both locking pieces 513 and 514 on opposite sides, respectively.

At the distance X3 between the locking piece 513 and the upper wall portion 502 of the sealing cap 500 and the distance X4 between the locking piece 514 and the lower wall portion 503, the sealing cap 500 is attached to the protrusions 418 and 204, respectively. At that time, the locking pieces 513 and 514 are set to be larger than the interval required for elastic deformation. As a result, when the sealing cap 500 is removed as described later, the upper wall portion 502 and the lower wall portion 503 can be easily cut from the main body portion 501 by a tool such as nippers.

A tab portion 515 as a grip portion is provided behind the main body portion 501. More specifically, a pair of connecting portions 517,518 are formed so as to project rearward from the upper part of the rear end of the left and right bulging portions 507,508, and are substantially flat so as to connect the rear ends of the connecting portions 517,518. The tab portion 515 is connected. The tab portion 515 extends parallel to the upper wall portion 502, and its left and right end portions project further outward than the bulging portions 507 and 508. A predetermined identification mark such as a manufacturer name, a model name, a serial number, etc. is attached to the tab portion 515 (not shown).

Subsequently, the procedure for attaching the sealing cap 500 will be described.

After attaching the connector cover 411 to the board box 201, the sealing cap 500 is attached in the direction shown in FIG. 7 toward the protrusion 418 of the connector cover 411 and the protrusion 204 of the box cover 203 in the superimposed state.

When the protrusions 418 and 204 are inserted into the main body 501 from the front side of the sealing cap 500 along the grooves 509 and 510, the protrusions 418 and 204 come into contact with the locking claws 513a and 514a. While elastically deforming the locking pieces 513 and 514, they are inserted into the interior.

When the tips of both protrusions 418 and 204 pass through the opening 511 and are substantially flush with the outer surface of the back wall portion 506, the locking claws 513a and 514a reach the through holes 418a and 204a and the locking pieces 513 and 514. Returns to its original state. That is, the locking claws 513a and 514a enter the through holes 418a and 204a and are locked to both protrusions 418 and 204, so that the sealing cap 500 is completely attached (see FIG. 9).

When the attachment of the sealing cap 500 is completed, the surroundings of the locking claws 513a and 514a are surrounded by the main body 501 of the sealing cap 500. Therefore, the locking pieces 513 and 514 cannot be directly operated from the outside, and the sealing cap 500 cannot be removed from both the protrusions 418 and 204. As a result, the movement of the connector cover 411 in the removing direction (upward in FIG. 9) is restricted, and the connector cover 411 is irremovably attached to the board box 201.

As described above, when the connector cover 411 is in the attached state, its tilt is restricted. Therefore, even if the lock by the locking claw 415 of the arm portion 414 can be temporarily released, the seal of the sealing cap 500 is not released. As long as it is, the connector CN of the connection cable CC cannot be removed.

Therefore, if it becomes necessary to disconnect the connector CN of the connection cable CC for a legitimate reason such as when replacing the board box 201, the procedure is as follows.

First, using a tool such as nippers, the upper wall portion 502 of the sealing cap 500 is cut from the main body portion 501 (see the cutting line S in FIG. 15). As a result, the upper part of the main body 501 is opened, and the locking piece 513 can be operated.

Then, the sealing cap 500 is removed by picking the tab portion 515 and pulling it diagonally upward to the left in FIG. 9 to release the engagement state between the locking claw 513a of the locking piece 513 and the protrusion 418. To. Of course, instead of or in addition to the upper wall portion 502, the lower wall portion 503 may be cut to remove the sealing cap 500.

When the sealing cap 500 is removed, the connector cover 411 can be removed, and by removing the connector cover 411, the connector CN of the connection cable CC can be removed.

On the other hand, by using the unused sealing cap 500, the connector cover 411 can be attached again without being removed.

Similar to the sub control device 111, the connector covers 411A and 411B and the sealing caps 500A and 500B having the same configurations as the connector cover 411 and the sealing cap 500 are attached to the main control device 131 and the operation relay board 112, respectively. (See Figures 3 and 4).

Next, the electrical configuration of the slot machine 10 will be described with reference to the block diagram of FIG.

The main control device 131 is equipped with a microcomputer centered on the CPU 151. In addition to the power supply device 161 provided inside the power supply box 121, a clock circuit 154 that outputs a rectangular wave having a predetermined frequency, an input / output port 155, and the like are connected to the CPU 151 via an internal bus.

On the input side of the main controller 131, there are a start detection sensor 71a that detects the operation of the start lever 71, a stop detection sensor 72a, 73a, 74a that individually detects the operation of each of the stop switches 72, 73, 74, and a medal insertion slot. Insertion medal detection sensor 75a that detects the medals inserted from 75, credit insertion detection sensors 77a, 78a that individually detect the operation of each credit insertion switch 77, 78, changeover detection sensor 80a that detects the operation of the changeover switch 80, Reel index sensors 55L, 55M, 55R that individually detect the rotation position of each reel 42L, 42M, 42R, payout detection sensor 91a that detects medals paid out from the hopper device 91, reset detection sensor 640 that detects reset operation, setting Various sensors such as a setting key detection sensor 124a for detecting that a setting key has been inserted into the key insertion hole 124 and an opening detection switch 820 (see FIG. 4) for detecting the opening of the front door 12 are connected. Signals from these various sensors are output to the CPU 151 via the input / output port 155. The start detection sensor 71a, the stop detection sensor 72a, 73a, 74a, the insertion medal detection sensor 75a, the credit insertion detection sensor 77a, 78a, and the switching detection sensor 80a are mainly connected via the operation relay board 112 as described above. Although it is connected to the control device 131, the operation relay board 112 is omitted in the block diagram of FIG. 6 for convenience.

The inserted medal detection sensor 75a is actually composed of a plurality of sensors. That is, the storage passage 81 from the medal insertion slot 75 to the hopper device 91 is configured so that medals can pass in one row in the upstream portion thereof. A first sensor is provided in the upstream portion of the storage passage 81, and the second sensor and the third sensor are close to each other on the downstream side separated by the width of the medal or more (at least for a certain period of time, the same medal is detected at the same time). The inserted medal detection sensor 75a is configured by each of the first to third sensors. The main control device 131 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, it considers that the medal is jammed or fraudulent and makes an error. When an error occurs, the operation by the player until the error is notified and the error is cleared is invalidated. The main control device 131 also monitors the order in which the second sensor and the third sensor are turned on and off, and the second and third sensors are both off, only the second sensor is on, and the second and third sensors are both on. , Only when only the 3rd sensor is on and both the 2nd and 3rd sensors are off, and when the time to shift to each on / off switching is within the predetermined time, it is judged that the medal is normally captured. However, in other cases, an error occurs. This is done in order to prevent medals from being jammed in the storage passage 81 and to prevent fraud in which medals are reciprocated in the vicinity of the inserted medal detection sensor 75a to be mistaken for inserted medals.

Further, a power failure monitoring circuit 161b provided in the power supply device 161 is connected to the input side of the main control device 131 via the input / output port 155. The power supply device 161 is equipped with a power supply unit 161a that supplies drive power to each electronic device of the slot machine 10, including the main control device 131, and the above-mentioned power failure monitoring circuit 161b.

The power failure monitoring circuit 161b monitors the power cutoff state and generates a power failure signal not only when the power is cut off but also when the power supply is cut off by the power switch 122. In this example, the stabilized drive voltage of DC 12 volt is monitored, and when this drive voltage drops to less than 10 volt, it is determined that the voltage is cut off and a power failure signal is output. The power failure signal is supplied to each of the CPU 151 and the input / output port 155, and the CPU 151 recognizes the power failure signal to execute a predetermined power failure processing.

Even if the output voltage drops to less than 10 volts from the power supply unit 161a, a regulated voltage of 5 volts, which is used as a drive voltage in a control system such as the main control device 131, is output. As the time during which the regulated voltage is output, a sufficient time is secured for executing the power failure processing by the main controller 131.

To rotate each effective line display unit 32, 33, 34, remaining number display unit 35, game number display unit 36, acquired number display unit 37, and reels 42L, 42M, 42R on the output side of the main control device 131. The stepping motors 61L, 61M, 61R, the medal passage switching solenoid 83 provided in the selector 84, the hopper device 91, the sub control device 111, the external centralized terminal plate 171 that can transmit information to the hall management device of the game hall, etc. It is connected via the input / output port 155.

After receiving the signal from the main control device 131 as described above, the sub control device 111 independently drives and controls the upper lamp 13, the speakers 14A and 14B, and the auxiliary display unit 15.

The CPU 151 described above has a ROM 152 that stores various control programs and fixed value data executed by the CPU 151, and an operation that temporarily stores various data when executing the control program stored in the ROM 152. In addition to the RAM 153 for securing the area, as is well known, various processing circuits required in the slot machine 10 such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit, and a credit counter that counts the number of credits, as is not shown, Various counters such as are built-in. A main memory as a storage means is configured by the ROM 152 and the RAM 153, and a program for executing various processes is stored in the ROM 152 described above as a part of the control program.

The RAM 153 has a configuration in which a backup voltage is supplied from the power supply device 161 provided in the power supply box 121 to hold (back up) data even after the power supply of the slot machine 10 is cut off. A backup area is provided in addition to a memory and an area for temporarily storing various data and the like.

In the backup area, when the power is cut off due to a power failure or the like, the stack pointer at the time of power cutoff (including power cutoff by operating the power switch 122; the same applies hereinafter), each register, the value of I / O, etc. It is an area for storing the above, and when the power failure is resolved (including turning on the power by operating the power switch 122. The same applies hereinafter), the state of the slot machine 10 is set to the state before the power is cut off based on the information in the backup area. It is possible to return to the state. Writing to the backup area is executed when the power is cut off due to power failure processing, and restoration of each value written in the backup area is executed in the main processing when the power is turned on. The NMI terminal (non-maskable interrupt terminal) of the CPU 151 is configured to input a power failure signal from the power failure monitoring circuit 161b when the power is cut off due to a power failure or the like, and the NMI is associated with the occurrence of a power failure or the like. Interrupt processing is executed immediately.

Therefore, if the power is shut off in the normal procedure as in the case where the game hall is closed, the state before the shutoff is stored in memory, but if the power switch 122 is turned on while performing a reset operation, the backup data is reset. It has become like. The reset operation is performed by inserting the key into the cylinder lock 700 and rotating it in the counterclockwise direction when viewed from the front side of the slot machine 10. Then, the reset detection sensor 640 (see FIG. 3) detects the operation of the locking device 600 related to this operation, and outputs a detection signal to the main control device 131. Based on this detection signal, the main control device 131 can grasp that the reset operation has been performed. As a result, it is possible to reset an error state such as a hopper error without opening the front door 12.

The power supply unit 161a of the power supply device 161 holds the output of the regulated voltage (5 volts) used as the drive voltage of the control system for a sufficient time to execute the above-mentioned NMI interrupt processing and power failure processing. It is configured to. In the present embodiment, the drive voltage is continuously output for 30 msec.

As described in detail above, according to the present embodiment, the connector cover 411 that regulates the movement of the connector CN of the connection cable CC connected to the terminal portion 401 or the like of the sub control device 111 in the disconnection direction is provided in the board box 201. Can be installed. Therefore, in the mounted state of the connector cover 411, even if the connector CN of the connection cable CC is illegally removed and a malicious act is performed, it is difficult to remove the connector CN. The act can be deterred.

Moreover, the sealing cap 500 is irremovably attached so as to straddle both the protrusion 418 of the connector cover 411 and the protrusion 204 of the box cover 203, and the connector cover 411 cannot be removed from the board box 201. Therefore, in the unlikely event that the connector cover 411 or the sealing cap 500 is forcibly removed, some traces such as partial damage will remain, and the connector cover 411 or the sealing cap 500 will be returned to the original position. Since it cannot be installed properly as in the state, the fraudulent activity can be detected early and easily by confirming it. Therefore, not only the direct prevention of fraudulent activity but also the deterrence of fraudulent activity can be achieved from the aspect of early detection of fraudulent activity. As a result, it becomes difficult to connect an unauthorized device such as a driving machine without leaving a trace.

Unlike the configuration of the present embodiment, a caulking member such as a one-way screw may be internally inserted into the hole formed in the protrusion to fasten both protrusions, but in such a configuration, the caulking member is attached. It takes time and effort to perform the work, and it may take time and effort to confirm whether or not the caulking member is properly attached.

It is also conceivable to provide through holes in both protrusions and fasten both protrusions with a binding band or the like, but in such a configuration, the band portion of the binding band is inserted through the through holes of both protrusions in a very fine manner. Since it requires troublesome work, work efficiency may deteriorate.

In this respect, in the present embodiment, since the sealing cap 500 is mounted so as to wrap the protruding portions 418 and 204 formed on the protrusions, the mounting and removing work is facilitated, and the mounting state can be easily confirmed. Can be done.

As a result, according to the present embodiment, it is possible to secure sufficient protection performance against fraudulent activities and improve maintainability at the same time.

Further, when the attachment of the sealing cap 500 is completed, the tips of both protrusions 418 and 204 pass through the opening 511 and become substantially flush with the outer surface of the back wall portion 506. This makes it possible to easily confirm from the outside of the main body 501 whether or not the sealing cap 500 is properly attached.

The content is not limited to the description of the above-described embodiment, and may be implemented as follows, for example.

(A) The configuration of the sealing cap 500 is not limited to the above embodiment. For example, a slit for cutting or a thin-walled portion as a breaking portion may be formed along the cutting line S in FIG. According to such a configuration, the cutting work of the upper wall portion 502 and the like can be easily performed.

Further, as shown in FIG. 16, slits 610 are intermittently provided along the upper wall portion 502 at the upper portions of the left wall portion 504, the right wall portion 505, and the back wall portion 506, and the upper portion of the upper wall portion 502. The tab portion 612 may be provided on the surface. Further, a notch 614 may be provided in a part of the connecting portion 613 connecting the left wall portion 504, the right wall portion 505, the back wall portion 506, and the upper wall portion 502. The left and right ends of the tab portion 612 project further outward than the bulging portions 507 and 508, and the thickness (front-rear width) thereof is larger than the thickness of the connecting portion 613.

Under such a configuration, the upper wall portion 502 can be separated from the main body portion 501 by gripping and twisting the tab portion 612 and cutting the connecting portion 613. In this way, the upper wall portion 502 can be cut from the main body portion 501 by simply applying force with bare hands without using a tool such as nippers.

The size of the tab portion 612 is not limited to that shown in FIG. 16, but in consideration of cutting the upper wall portion 502, it is preferable to adopt a relatively large tab portion that is easier to apply force.

The number of connecting portions 613 is also not particularly limited, but from the viewpoint of cutting the upper wall portion 502, at least one each corresponding to the left wall portion 504, the right wall portion 505, and the back wall portion 506, for a total of 3 It is preferable to provide this. Among them, from the viewpoint of preventing fraudulent activity, as shown in FIG. 16, one connecting portion 613 is provided at each of the front end portions of the left wall portion 504 and the right wall portion 505 on the side where the locking claws 513a and 514a are located.

Hereinafter, technical ideas that are not described in the claims and can be grasped from the above-described embodiment will be described together with their effects.

Means 1. A board provided with a terminal portion (board-side connector) for transmitting or receiving a signal to or from a predetermined electric device, and a board.
It is provided with an encapsulating member (board box) that encloses the substrate in a state where the terminal portion is exposed.
In a gaming machine in which a connector (cable side connector) of a connection cable electrically connected to the electric device is connected to the terminal portion.
A covering member (connector cover) that is detachably attached to the encapsulating member so as to cover the terminal portion and regulates the movement of the connection cable connected to the terminal portion in the disconnection direction.
The first protrusion formed on the covering member and
A second protrusion formed so as to protrude in parallel with the first protrusion from the encapsulating member or a predetermined member assembled to the encapsulating member.
A lid member (sealing cap) that is irremovably attached to both of the first protrusions and the second protrusions is provided so as to wrap the first protrusions and the second protrusions.
A gaming machine characterized in that the covering member cannot be removed from the encapsulating member when the lid portion is attached.

Here, "covering member" and "lid member" are "non-removable" because the covering member, lid member, etc. cannot be removed or extremely unless, for example, the covering member, lid member, etc. are cut or destroyed. It means that it is difficult.

According to the above means 1, a covering member that regulates the movement of the connection cable connected to the terminal portion in the disconnection direction is attached to the encapsulating member. For this reason, in the state where the covering member is attached, even if an attempt is made to perform a malicious act after illegally removing the connector of the connection cable, it is difficult to remove the connector, and such an act is suppressed. be able to.

Moreover, the lid member is irremovably attached so as to straddle both the covering member (first protrusion) and the encapsulating member (second protrusion), and the covering member cannot be removed from the encapsulating member. Therefore, in the unlikely event that a fraudulent act such as forcibly removing the covering member or lid member is performed, some traces such as partial damage will remain, and the covering member or lid member will be restored to its original state. Since it cannot be properly attached to the lid, the fraudulent activity can be detected early and easily by confirming it. Therefore, not only the direct prevention of fraudulent activity but also the deterrence of fraudulent activity can be achieved from the aspect of early detection of fraudulent activity.

Conventionally, in a game hall where a game machine such as a slot machine is installed, there is a store that provides a so-called "morning" service as a means of attracting customers.

The "morning" service in slot machines is to set the slot machine in an internal winning state on the hall side in advance before the start of business, and to operate the slot machine in a state where the player can play a bonus game from the time of opening the hall. By doing so, the player can obtain a bonus game with a reduced initial investment.

Such a "morning" service may affect the performance of the game machine, such as a predetermined winning probability, and may impair fairness between players or game halls. In addition, it fuels the gambling spirit of the players and contributes to the excessive investment of game funds.

As a device that intentionally creates an internal winning state, an illegal device called a "driving machine" is known. The driving machine artificially inputs signals output from various operating means operated by the player according to the progress of the game to the main board, and does not operate the operating means until the bonus flag is set. The game progresses automatically (until the internal winning is won).

To connect the driving machine to the slot machine, first remove the connector of the connection cable extending from the operating means such as the start lever and stop switch from the terminal part of the main board (or relay board), and instead control the connector of the driving machine. This is done by connecting to the terminal part of the board. Furthermore, by connecting the connector of the connection cable extending from the main board to the sub board etc. to the driving machine, when the internal winning is done, the winning signal etc. originally output to the sub board etc. is sent to the driving machine. It is input and it can be recognized that the driving machine has won the internal winning.

On the other hand, according to this means, it becomes difficult to connect an unauthorized device such as a driving machine without leaving a trace, so that the above-mentioned fraudulent activity can be suppressed. Of course, this means is not limited to this, and also for other fraudulent acts that connect fraudulent devices, for example, fraudulent acts such as attaching a separate board to the connection cable or terminal, so-called "hanging". It is valid.

On the other hand, when the board box is replaced due to a legitimate reason such as a failure, the lid member may be destroyed and removed. After removing the lid member, the covering member is removed from the encapsulating member, and the connector of the connection cable is pulled out, so that the board box can be replaced. When the sealing process is performed again after replacing the substrate box, the covering member may be attached to the encapsulating member, and then a new lid member may be attached to the protrusion.

Unlike the configuration of this means, a caulking member such as a one-way screw may be internally inserted into the hole formed in the protrusion to fasten both protrusions, but in such a configuration, the caulking member is attached. It takes time and effort, and it may take time and effort to confirm whether or not the caulking member is properly attached.

It is also conceivable to provide through holes in both protrusions and fasten both protrusions with a binding band or the like, but in such a configuration, the band portion of the binding band is inserted through the through holes of both protrusions in a very fine manner. Since it requires troublesome work, work efficiency may deteriorate.

In this respect, since the lid member is mounted so as to wrap the protruding portion formed by the protrusion in this means, the mounting and removing work can be facilitated, and the mounting state can be easily confirmed.

For example, in a slot machine, a sub-board, a relay board, or the like is provided behind a front door on which an operating means such as a stop switch is provided. Therefore, as compared with the main board or the like provided on the housing side, the sub board or the like is more likely to have a problem due to the influence of vibration or the like during operation such as when the player bangs the operation means. That is, there is a possibility that the frequency of inspection and replacement after removing the connector of the connection cable and further removing the sub-board or the like from the front door may increase, so that the configuration of this means becomes more effective.

In the mounted state of the lid member, the lid member is in a protruding state, and there is a possibility that illegal release of the seal may be easily performed as compared with the above-mentioned configuration in which the caulking member is internally inserted, but by any chance the lid member is forcibly pulled. When a fraudulent act such as removal is performed, some traces such as partial damage remain, and the fraudulent act can be detected early and easily, so that no particular problem is unlikely to occur.

As a result, according to this means, it is possible to secure sufficient protection performance against fraudulent activities and improve maintainability at the same time.

Examples of the "electrical device" include other boards (sub-boards, relay boards, etc.) that transmit or receive signals from the above-mentioned "board", and operating means such as a start lever and a stop switch. Listed in.

Further, as the "predetermined member to be assembled to the encapsulated member" in which the second protrusion is formed to protrude, for example, the base member for mounting the encapsulated member at a predetermined position and the connector cover are assembled to the encapsulated member.
