  Hereinafter, an embodiment in the case of application to a spinning cylinder type gaming machine which is a kind of gaming machine, specifically, a slot machine will be described in detail based on the drawings. 1 is a front view of the slot machine 10, FIG. 2 is a perspective view of the slot machine 10 with the front door 12 closed, FIG. 3 is a perspective view of the slot machine 10 with the front door 12 opened, and FIG. 5 is a rear view of the door 12, and FIG.

  As shown in FIGS. 1 to 5, the slot machine 10 includes a housing 11 that forms an outer shell thereof. The housing 11 includes a top plate 11a, a bottom plate 11b, a back plate 11c, a left side plate 11d, and a right side plate 11e, and is formed in a box shape with the front surface opened as a whole.

  A front door 12 is attached to the front side of the housing 11 so as to be openable and closable. That is, the housing 11 is provided with a pair of upper and lower support shafts 13a and 13b on the left side when viewed from the front, and the front door 12 has a bearing portion 14a at a position corresponding to each support shaft 13a and 13b. , 14b are provided. When the support shafts 13a and 13b are inserted into the bearing portions 14a and 14b, the front door 12 rotates about an opening / closing axis extending in the vertical direction connecting the support shafts 13a and 13b to the housing 11. The front door 12 can be opened and closed by rotating the front door 12 so as to be movable. Further, the front door 12 is brought into a locked state that cannot be opened by a locking device 20 provided on the back surface thereof. A key cylinder 21 that is integrated with the locking device 20 is provided on the upper right side of the front door 12, and is configured such that the locked state is released by a predetermined key operation on the key cylinder 21.

  A game panel 25 for notifying the player of the game state is provided above the center of the front door 12. The game panel 25 is formed with three vertically long display windows 26L, 26M, and 26R, and the inside of the slot machine 10 is visible through the display windows 26L, 26M, and 26R. The display windows 26L, 26M, and 26R may be combined into a single display window.

  As shown in FIG. 3, the inside of the housing 11 is divided into upper and lower parts by a partition plate 30, and a reel unit 31 constituting variable display means is attached to the upper part of the partition plate 30. The reel unit 31 includes a left reel 32L, a middle reel 32M, and a right reel 32R each formed in a cylindrical shape (annular shape). Each of the reels 32L, 32M, and 32R is rotatably supported so that the central axis thereof is the rotation axis of the reel. The rotation axes of the reels 32L, 32M, and 32R are disposed on the same axis extending in the substantially horizontal direction, and the reels 32L, 32M, and 32R correspond to the display windows 26L, 26M, and 26R on a one-to-one basis. . Accordingly, a part of the surface of each reel 32L, 32M, 32R is visible through the corresponding display windows 26L, 26M, 26R. Further, when the reels 32L, 32M, and 32R are rotated forward, the surfaces of the reels 32L, 32M, and 32R are projected as if moving from top to bottom through the display windows 26L, 26M, and 26R.

  Here, the configuration of the reel unit 31 will be briefly described.

  Each of the reels 32L, 32M, and 32R is connected to a stepping motor, and each reel 32L, 32M, and 32R can be individually rotated, that is, independently driven by the driving of each stepping motor. . For example, the stepping motor is set to rotate once by giving a drive signal of 504 pulses (hereinafter also referred to as an excitation pulse), and the rotation position of the stepping motor, that is, the rotation position of the reel is determined by this excitation pulse. Be controlled. In the reel unit 31, a reel index sensor for detecting that the reel has made one rotation is installed on each of the reels 32L, 32M, and 32R. When the reel index sensor detects that the reel has made one rotation, a detection signal is output to the main controller 101 described later each time the reel is detected. Therefore, main controller 101 determines the angular position of each reel 32L, 32M, 32R for each rotation based on the detection signal of the reel index sensor and the number of excitation pulses output until the detection signal is input. It can be confirmed and corrected.

  On the outer peripheral surface of each reel 32L, 32M, 32R, a plurality of symbols as identification information are drawn in the long side direction (circumferential direction). More specifically, 21 symbols are drawn at equal intervals. Therefore, in order to switch the symbol at a predetermined position to the next symbol, it is necessary to output 24 pulses (= 504 pulses / 21 symbols) of excitation pulses. Further, the main control device 101 grasps the symbols visible from the display windows 26L, 26M, and 26R based on the number of excitation pulses output after the detection signal of the reel index sensor is input, or displays the display window. It is possible to perform control to stop a predetermined symbol at a position where it can be visually recognized from 26L, 26M, and 26R.

  Each of the display windows 26L, 26M, and 26R is formed so that there are three symbols from which the entire symbol can be visually recognized out of the twenty-one symbols attached to the corresponding reel. Therefore, when all the reels 32L, 32M, and 32R are stopped, 3 × 3 = 9 symbols are visible through the display windows 26L, 26M, and 26R. In this slot machine 10, a total of five combination lines are set, connecting three positions where these nine symbols become visible, three in parallel in the horizontal direction and two in the diagonal direction. ing. When the combination line is activated, that is, when the symbols are stopped on the effective line in a predetermined combination, a bonus that a predetermined number of medals as game media are paid out is given as a winning combination, or a big bonus (hereinafter, referred to as a bonus) The privilege that the game state is shifted to the state or the like is also given.

  On the lower left side of the game panel 25, a start lever 41 that is operated to start rotation of the reels 32L, 32M, and 32R is provided. The start lever 41 constitutes start operation means or start operation means operated to start rotation of the reels 32L, 32M, and 32R, that is, to start variable display of symbols. When the start lever 41 is operated while a predetermined number of medals are inserted, the reels 32L, 32M, and 32R start to rotate.

  On the right side of the start lever 41, button-like stop switches 42 to 44 that are operated to individually stop the rotating reels 32L, 32M, and 32R are provided. Each of the stop switches 42 to 44 is disposed immediately below the display windows 26L, 26M, and 26R corresponding to the reels 32L, 32M, and 32R to be stopped. That is, when the left stop switch 42 is operated, the rotation of the left reel 32L is stopped. When the middle stop switch 43 is operated, the rotation of the middle reel 32M is stopped and the right stop switch 44 is operated. In this case, the rotation of the right reel 32R is stopped. The stop switches 42 to 44 constitute stop operation means operated to stop the variable display of symbols based on the rotation of the reels 32L, 32M, 32R.

  On the lower right side of the display windows 26L, 26M, 26R, a medal insertion slot 45 for inserting medals is provided. The medal slot 45 constitutes an input means for inputting game media. If attention is paid to the point that the medal insertion slot 45 is directly inserted by the player, it can be said that it constitutes a direct input means for directly inputting the game medium.

  The medals inserted from the medal insertion slot 45 are guided to either the storage passage 47 or the discharge passage 48 by a selector 46 as passage switching means provided on the back surface of the front door 12. More specifically, the selector 46 is provided with a medal path switching solenoid 46a. When the medal path switching solenoid 46a is not excited, the medal is guided to the discharge path 48, and when the medal path switching solenoid 46a is excited, the medal is switched. Is guided to the storage passage 47 side. The medal guided to the storage passage 47 is guided to the hopper device 51 housed inside the housing 11. On the other hand, the medal guided to the discharge passage 48 is guided to the medal tray 50 from the medal discharge port 49 provided in the lower front portion of the front door 12 and returned to the player.

  The hopper device 51 includes a storage tank 52 that stores medals, and a payout device 53 that pays out medals to a player. The payout device 53 rotates a medal payout rotating plate (not shown) to discharge the medal to the opening 48 a provided in the discharge passage 48 and to pay out the medal to the medal tray 50 through the discharge passage 48. It has become. Further, a reserve tank 54 is provided on the right side of the hopper device 51 to avoid storing a predetermined amount or more of medals in the storage tank 52. Inside the storage tank 52 of the hopper device 51, a guide plate 52a for discharging medals from the storage tank 52 to the reserve tank 54 is provided. Therefore, when medals are stored more than the height at which the guide plate 52 a is provided, the medals are stored in the reserve tank 54.

  A button-like return switch 55 is provided below the medal slot 45. When the return switch 55 is operated in a situation where a medal inserted into the medal insertion slot 45 is jammed in the selector 46, the selector 46 is mechanically operated so that the medal jammed in the selector 46 becomes a medal. It is returned from the discharge port 49.

  On the lower left side of the display windows 26L, 26M, 26R, there is provided a first credit insertion switch 56 for inserting three credited virtual medals as game media at a time. Further, a second credit insertion switch 57 and a third credit insertion switch 58 are provided on the left side of the first credit insertion switch 56. The second credit insertion switch 57 is for inserting two virtual medals at a time, and the third credit insertion switch 58 is for inserting one virtual medal. Each of the credit insertion switches 56 to 58 constitutes input means for inputting a game medium together with the medal insertion slot 45. It should be noted that the medal insertion slot 45 is accompanied by an operation of directly inserting a medal by the player, whereas each of the credit insertion switches 56 to 58 is only accompanied by an operation of inserting a virtual medal based on the storage memory. In other words, it can be said to constitute indirect input means for indirectly inputting game media.

The first lid member 132 is formed of a transparent synthetic resin material, and has a main body portion 132a formed in a horizontally long rectangular flat plate shape, and extends rearward from the main body portion 132a at the upper left end of the main body portion 132a. A return plate portion 132b is formed. The return plate portion 132b is formed such that the dimension in the front-rear direction is slightly shorter than the dimension in the front-rear direction of the second groove 137b, and the dimension in the left-right direction is the left-right direction of the notch 137c of the second groove 137b. It is formed to be slightly shorter than the dimensions. In the lower right portion of the main body portion 132a, a vertically long flat plate-like protrusion 132c extending downward, that is, toward the second lid member 142 is formed. Also, a guide groove 142e extending in the left-right direction is formed on the front surface of the second lid member 142, the return plate 132b is inserted into the second groove 137b, and the protrusion 132c is inserted into the guide groove 142e. In the state, the first lid member 132 is supported so as to be slidable in the left-right direction with respect to the reset switch housing part 131, and the front open side of the reset switch housing part 131 is opened or closed by the sliding movement of the first lid member 132. You can do that. In this configuration, when the first lid member 132 is in the closed position shown in FIG. 6, the front side of the reset switch 104 is covered by the first lid member 132, and the first lid member 132 is in the open position shown in FIG. In some cases, the reset switch 104 is exposed.

  The setting key switch accommodating portion 141 has a bottom plate portion 143 extending in parallel with the main substrate, and an opening hole having a slightly larger outer diameter than the setting key switch 105 at a position corresponding to the setting key switch 105 of the bottom plate portion 143. 143a is formed. Further, the setting key switch accommodating portion 141 has a rectangular frame-shaped wall portion 145 that is formed upright from the peripheral edge portion of the bottom plate portion 143 to the front. In the present embodiment, the reset switch 104, the setting key switch 105, the reset switch housing 131, and the setting are shared by commonly using the lower wall 135c of the reset switch housing 131 as the upper wall of the setting key switch housing 141. The key switch accommodating portion 141 is arranged in a concentrated manner. A plurality of reinforcing ribs 146 are formed on the upper side wall portion and the lower side wall portion of the wall portion 145 on the setting key switch 105 side, that is, inside the setting key switch housing portion 141. The reinforcing rib 146 is formed along the corresponding wall portion from the bottom plate portion 143 and has a slightly shorter front-rear dimension than the wall portion. More specifically, the longitudinal dimension of the reinforcing rib 146 is obtained by subtracting the thickness dimension of the second lid member 142 from the longitudinal dimension of the wall portion. A concave portion is formed in the center portion of the right side wall portion of the wall portion 145, and a pair of upper and lower bearing portions 147a and 147b are formed so as to sandwich the concave portion. The left side wall portion of the wall portion 145 has a shorter front-rear dimension than the surrounding wall portion. Specifically, the front-rear dimension of the left side wall portion is equal to the front-rear dimension of the surrounding wall portion minus the thickness dimension of the second lid member 142, that is, the front-rear dimension of the reinforcing rib 146.

  A second lid member 142 is pivotally attached to the front side of the setting key switch accommodating portion 141. The second lid member 142 is made of a transparent synthetic resin material, and has a main body part 142a formed in a horizontally long rectangular flat plate shape, and a pair of left and right support shafts 142b formed on one side of the main body part 142a, 142c. When the support shafts 142b and 142c are inserted in the bearing portions 147a and 147b, the second lid member 142 opens and closes in the vertical direction connecting the support shafts 142b and 142c to the setting key switch housing portion 141. It is supported so as to be pivotable in the left-right direction around the axis, and the front open side of the setting key switch accommodating portion 141 can be opened or closed by the rotation of the second lid member 142. In such a configuration, when the second lid member 142 is in the closed position shown in FIG. 6, the front side of the setting key switch 105 is covered by the second lid member 142, and the second lid member 142 is in the open position shown in FIG. The setting key switch 105 is exposed. Further, when the second lid member 142 is in the closed position, the rear surface of the main body portion 142a of the second lid member 142 abuts on the distal end surface of the reinforcing rib 146 and the distal end surface of the left side wall portion of the setting key switch accommodating portion 141, The front surface of the main body portion 142a and the front end surfaces of the upper and lower side wall portions are located on the same plane. An opening 142d that penetrates forward and backward and opens upward is formed in the upper portion of the main body 142a. As shown in FIG. 12, the opening 142d has a shape that allows the protrusion 132c of the first lid member 132 to be inserted back and forth. In addition, a guide groove 142e having a substantially L-shaped cross section extending in the left-right direction is formed on the front surface of the main body 142a so as to straddle the opening 142d. Closed wall portions 142f are formed at both left and right ends of the guide groove portion 142e, and the guide groove portion 142e has a shape that is open only upward except for a position corresponding to the opening portion 142d. On the rear surface of the main body 142a of the second lid member 142, a shielding rib 142g is formed so as to extend along the sides where the support shafts 142b and 142c are formed and the sides excluding the opening 142d. When the second lid member 142 is in the closed position, the shielding rib 142g is located on the inner side of the reinforcing rib 146 of the setting key switch housing portion 105 and on the side surface facing the setting key switch 105 of the reinforcing rib 146 in the vertical direction. It is formed at a position where it abuts.

  Here, the attaching operation of the first lid member 132 and the second lid member 142 will be described.

  When the second lid member 142 is attached to the setting key switch accommodating portion 141, the support shafts 142b and 142c of the second lid member 142 are inserted into the bearing portions 147a and 147b of the setting key switch accommodating portion 141, respectively. Accordingly, the second lid member 142 is supported so as to be rotatable in the left-right direction with respect to the setting key switch accommodating portion 141.

  When attaching the first lid member 141 to the reset switch housing portion 141, as shown in FIG. 11A, first, the second lid member 142 is first opened from the setting key switch housing portion 141, and in this state, the extension wall portion The return plate portion 132b of the first lid member 132 is inserted into the cutout portion 137c of the second groove portion 137b formed at 136. Thereafter, as shown in FIG. 11B, the first lid member 132 is moved to the left so that the return plate portion 132b and the cutout portion 137c are displaced in the vertical direction. Thereby, the return plate part 132b can be locked to the second groove part 137b, and the first lid member 132 can be prevented from falling. Then, as shown in FIG. 12A, after positioning the first lid member 132 so that the protruding portion 132c of the first lid member 132 passes through the opening 142d of the second lid member 142, the second lid The member 142 is turned to the closing side (that is, leftward) to close the setting key switch accommodating portion 141. As a result, the return plate portion 132b is inserted into the second groove portion 137b and the leading end of the protruding portion 132c is inserted into the guide groove portion 142e, and as shown in FIG. The container 131 is supported so as to be slidable in the left-right direction. Note that the opening 142d of the second lid member 142 is the first when the first lid member 132 is positioned so that the protrusion 132c of the first lid member 132 passes through the opening 142d of the second lid member 142. The return plate portion 132b and the cutout portion 137c of the lid member 132 are formed at positions that are shifted in the vertical direction. For this reason, even if it is a case where the 1st cover member 132 is positioned so that it may become the said positional relationship, the return plate part 132b can be latched by the 2nd groove part 137b, and it can prevent that the 1st cover member 132 falls.

  Next, the operation of the first lid member 132 and the second lid member 142 will be described.

  When the first lid member 132 is slid and moved to the closed side (that is, to the right), the right side surface of the main body portion 132a of the first lid member 132 comes into contact with the right side wall portion 135b of the reset switch housing portion 131, so that The above slide movement is restricted. When the first lid member 132 is in a closed position (see FIG. 12B) where movement to the closed side is restricted, the front side of the reset switch 104 is covered by the first lid member 132. . At this time, the downward movement of the first lid member 132 is restricted by the return plate portion 132b engaging with the second groove portion 137b. In addition, when both the first lid member 132 and the second lid member 142 are in the closed position, as shown in FIG. 12B, the protruding portion 132 c of the first lid member 132 is formed on the second lid member 142. It is positioned in front of the main body 142a and shifted to the right from the opening 142d of the second lid member 142.

  When the first lid member 132 and the second lid member 142 are both slid from the closed position to the open side (that is, leftward), as shown in FIG. The left side surface of the return plate portion 132b contacts the left end surface of the second groove portion 137b, and further movement to the open side is restricted. When the first lid member 132 is in the open position where movement to the open side is restricted, the reset switch 104 is exposed and the reset switch 104 can be operated. When the first lid member 132 is in the open position and the second lid member 142 is in the closed position, the protruding portion 132c of the first lid member 132 is in front of the second lid member 142 and is second The lid member 142 is located at a position shifted to the left from the opening 142d.

  When the second lid member 142 is rotated to the closed side (that is, leftward), the rear surface of the main body portion 142a of the second lid member 142 comes into contact with the front end surface of the reinforcing rib 146 of the setting key switch accommodating portion 141, Further rotation is restricted. When the second lid member 142 is in a closed position (see FIG. 8) where movement to the closed side is restricted, the front side of the setting key switch 105 is covered by the second lid member 142 and the second lid member 142 is covered. The front surface of the main body 142a and the front end surface of the wall 145 are located on the same plane.

  When the first lid member 132 is in the closed position as shown in FIG. 12B, the protrusion 132c of the first lid member 132 is located in front of the main body portion 142a of the second lid member 142. The movement of the lid member 142 to the open side is restricted. Further, as shown in FIG. 8, even when the first lid member 132 is in the open position, the protruding portion 132 c of the first lid member 132 is located in front of the main body portion 142 a of the second lid member 142. The movement of the member 142 to the open side is restricted. On the other hand, when the first lid member 132 is moved to a position where the protruding portion 132c of the first lid member 132 and the opening 142d of the second lid member 142 overlap in the front-rear direction (see FIG. 12A). Since the protruding portion 132c of the first lid member 132 is not in front of the main body portion 142a of the second lid member 142, the restriction of the second lid member 142 by the protruding portion 132c is released, and the second lid member 142 is opened. It can be rotated to the right). In addition, in any case, the first lid member 132 is located at a position other than the restriction release position where the protrusion 132c of the first lid member 132 and the opening 142d of the second lid member 142 overlap each other. However, the protrusion 132c is positioned in front of the main body 142a of the second lid member 142, and the movement of the second lid member 142 to the open side is restricted. Thus, the second lid member 142 can be moved to the open side only when the first lid member 132 is in the restriction release position.

  When the second lid member 142 is rotated to the open side in a situation where the first lid member 132 is in the restriction release position, the side surface of the main body portion 142a of the second lid member 142 where the support shafts 142b and 142c are formed. Comes into contact with the side surface of the wall portion 145 of the setting key switch accommodating portion 141, and further rotation to the open side is restricted. When the second lid member 142 is in the open position (see FIG. 11B) where further movement to the open side is restricted, the setting key switch 105 is exposed and the setting key switch 105 is operated. be able to. For example, in a situation where the guide groove 142e of the second lid member 142 is not positioned below the protruding portion 132c of the first lid member 132, such as when the second lid member 142 is in the open position, the first lid Although there is a possibility that the member 132 falls, a position other than the position where the return plate portion 132b of the first lid member 132 and the cutout portion 137c of the second groove portion 137b coincide in the vertical direction as shown in FIG. By moving the first lid member 132, the return plate portion 132b can be locked with the second groove portion 137b, and the first lid member 132 can be prevented from falling.

  Next, specific work when the hall manager or the like changes the set value will be described.

  When changing the set value, first, the front door 12 is opened from the housing 11, and when the power is on, the power switch 71 is turned off to shut off the power. Thereafter, the first lid member 132 is moved from the closed position to the restriction release position, and then the second lid member 142 is rotated to the right from the closed position to move to the open position, so that the setting key switch 105 is exposed. Then, the setting key is inserted into the setting key switch 105 and turned on. When the power switch 71 is turned on in this state to turn on the power, the setting value of the slot machine 10 can be changed, and the setting value at that time (“1” in the present embodiment) is displayed on the setting display unit 106. ]) Is displayed.

  After turning on the power switch 71 to turn on the power, the first lid member 132 is moved from the restriction release position to the open position, and the reset switch 104 is exposed. Then, by pressing the reset switch 104, the setting value is changed to a setting value desired by the hall manager or the like. At this time, the setting display unit 106 displays a setting value that has been changed in accordance with the operation of the reset switch 104. When a setting value desired by the hall manager or the like is displayed on the setting display unit 106, the setting value is determined by operating the start lever 41. Thereafter, the setting key switch 105 is turned OFF, the setting key is removed from the setting key switch 105, the first lid member 132 is moved to the restriction release position, and the second lid member 142 is moved to the closed position. Then, after moving the first lid member 132 to the closed position, the front door 12 is closed. Since the slot machine 10 does not have a portion for displaying setting values except for the setting display unit 106 mounted on the main board 102, it is necessary to check the setting values through the setting display unit 106.

  Incidentally, when the hall manager or the like inserts the setting key into the setting key switch 105 and turns it on when the power is turned on, the setting value at that time is displayed on the setting display unit 106 and the setting value is displayed. Can be confirmed. At this time, even if the reset switch 104 is pressed, the set value cannot be changed.

  Here, the winning probability setting process executed by the main control device 101 when the setting change operation is performed will be described with reference to the flowchart of FIG. When the power is turned on by recovery from a power failure or turning on the power switch 71, the main controller 101 determines whether or not the setting key is inserted into the setting key switch 105 and is turned on. When the ON operation is performed, all the data (including data related to the set value) stored in the RAM is cleared as the forced RAM clear process, and then the winning probability setting process is performed. This slot machine 10 is prepared in advance with six stages of winning probabilities from “Setting 1” to “Setting 6”, and in the winning probability setting process, it is set which of the winning probabilities is used to execute the internal processing. To do.

  First, in step S101, the next timer interrupt is permitted. Thereafter, the current set value is read in step S102, and the current set value is displayed on the setting display unit 106 in step S103. However, in the process immediately after the setting key is inserted and the ON operation is performed, the RAM data is cleared by the previous forced RAM clear process, so the setting value displayed on the setting display unit 106 is the initial value “ 1 ”.

  In step S104, it is determined whether or not the start lever 41 is operated. If the start lever 41 is not operated, setting update processing shown in steps S105 to S106 is performed. In step S105, it is determined whether or not the reset switch 104 has been operated. If the reset switch 104 is not operated, the process directly returns to step S103. If the reset switch 104 is operated, the set value is updated by 1 in step S106, and then the process returns to step S103. That is, in the setting update process, every time the reset switch 104 is operated, the setting value is updated by 1, and the updated setting value is displayed on the setting display unit 106. If the reset switch 104 is operated when the set value is “6”, the set value is updated to “1”.

  If the start lever 41 is operated in step S104, it is determined in step S107 whether or not the setting key is continuously turned on. If the ON operation of the setting key is continued, the process waits as it is, and if the ON operation is completed (when the OFF operation is performed), the next timer interruption is prohibited in step S108. Thereafter, the set value is stored in step S109, and data other than the set value stored in the RAM is cleared in step S110, and this process is terminated.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  The first lid member 132 is provided on the front side of the reset switch housing part 131 so that the front side of the reset switch 104 is covered, and the second lid member 142 is provided on the front side of the setting key switch housing part 141 for setting. The front side of the key switch 105 is covered. With such a configuration, even if a wire or the like is inserted from the gap between the housing 11 and the front door 12 in order to change the set value illegally, the both ends of the wire and the like are reset by the both lid members 132 and 142. It can be difficult to reach the setting key switch 105.

  Certainly, even if the front side of the reset switch 104 and the setting key switch 105 is covered with one lid member, it is difficult to reach the wire or the like to the reset switch 104 or the setting key switch 105. can do. However, in such a configuration, when the lid member is pulled to the open position side by a wire or the like, both the reset switch 104 and the setting key switch 105 are exposed and can be operated. On the other hand, in the present embodiment in which each is covered with a separate lid member, it is necessary to pull each lid member to the open position side, so that the reset switch 104 and the setting key switch are compared with the configuration in which each lid member is covered. It can be difficult to expose the 105 together.

  On the other hand, when the front surfaces of the reset switch 104 and the setting key switch 105 are covered with the lid members 132 and 142 as described above, there is a possibility that the work when the hall manager or the like changes the setting becomes complicated. Although there is a concern, the reset switch 104 and the setting key switch 105 are centrally arranged on one side of the main board, and the first lid member 132 and the second lid member 142 are arranged adjacent to each other. It becomes possible to suppress.

  The first lid member 132 and the second lid member are arranged so that the direction in which the first lid member 132 moves from the closed position to the open position and the direction in which the second lid member 142 moves from the closed position to the open position are reversed. 142 was attached. With this configuration, even if a wire or the like is inserted from the gap between the housing 11 and the front door 12 and one lid member is pulled by the wire or the like so as to move to the open position side, the other lid member is It can prevent moving to an open position. Therefore, it is difficult to expose both the reset switch 104 and the setting key switch 105 even if a wire or the like is inserted from the gap between the housing 11 and the front door 12 without opening the front door 12 or slightly opening it. Therefore, it is possible to suitably suppress the setting from being illegally changed. Further, in order to move the lid members 132 and 142 to the open position using a wire or the like, it is necessary to insert a plurality of wires or the like from the gap between the housing 11 and the front door 12 and pull these wires or the like in different directions. is there. Therefore, it becomes possible to make the cheating act stand out, and it becomes possible to easily find the cheating action.

  A protrusion 132c extending toward the second lid member 142 side is provided at the lower right portion of the main body portion 132a of the first lid member 132 to restrict the second lid member 142 from rotating to the open side. In such a configuration, the second lid member 142 cannot be rotated to the open side unless the first lid member 132 is moved to the restriction release position. Further, in order to move both the lid members 132 and 142 to the open position, the lid members 132 and 142 are moved in a specific order of the first lid member 132 → the second lid member 142 → the first lid member 132. It can be said that it is necessary. In this way, the reset switch 104 and the setting key switch 105 are exposed on the condition that the lid members 132 and 142 are moved in a specific order, so that the front door 12 is not opened from the housing 11. Alternatively, it is possible to make it difficult to cheat by slightly opening the lid members 132 and 142 to the open position using a wire or the like from the gap between the housing 11 and the front door 12.

  The second lid member 142 is formed with an opening 142d so that the first lid member 132 can be rotated to the open side only when the first lid member 132 is located at the restriction release position between the closed position and the open position. By adopting such a configuration, it is possible to suitably suppress the setting value from being illegally changed. When a wire or the like is inserted from the gap between the housing 11 and the front door 12 and pulled by the wire or the like so that the first lid member 132 moves to the open side, the first lid member 132 passes through the restriction release position. When the first lid member 132 is in the open position, the second lid member 142 remains restricted from rotating to the open side. The second lid member 142 cannot be rotated to the open side. Accordingly, an unauthorized person who changes the setting value without opening the front door 12 from the housing 11 moves the first lid member 132 to the restriction release position in a situation where the displacement state of the first lid member 132 cannot be visually recognized. In order to further rotate the second lid member 142 to the open side, the first lid member 132 must be positioned and held at the restriction release position. Therefore, it is possible to make it difficult to expose the reset switch 104 and the setting key switch 105, and it is possible to appropriately suppress the setting value from being changed illegally.

  Since the first lid member 132 that covers the front side of the reset switch 104 is formed with a protruding portion 132c that restricts the rotation of the second lid member 142 to the open side, the work of the hole manager or the like is prevented from becoming complicated. It becomes possible to do. The reset switch 104 is a switch operated not only when the set value is changed but also when the slot machine 10 is returned from the error state. That is, the reset switch 104 may be operated during the business hours of the hall and is operated more frequently than the setting key switch 105. Therefore, by forming the protrusion 132c on the first lid member 132 that covers the front side of the reset switch 104, the first lid member 132 is moved to the open side without rotating the second lid member 142 to the open side. This makes it possible to prevent the hole manager or the like from complicating work when returning the slot machine 10 from the error state. Furthermore, when changing the setting value, it is necessary to operate the reset switch 104 after the setting key switch 105 is turned on. For this reason, by setting it as the structure which the rotation of the 2nd cover member 142 which covers the setting key switch 105 operated previously is controlled by the 1st cover member 132 which covers the reset switch 104 operated later, a setting value is set. It is possible to reduce the motivation of the fraudulent person who changes the fraudulently, and it is possible to expect a deterrent effect of the fraudulent act itself that illegally changes the set value.

  Since the protrusion 132c is formed on the first lid member 132 to restrict the rotation of the second lid member 142, the first lid member 132 is closed before the second lid member 142 after the set value is changed. In the case where the second lid member 142 is moved to the closed position, the projection 132c of the first lid member 132 cannot move the second lid member 142 to the closed position. More specifically, when the second lid member 142 is rotated to the closed side after the first lid member 132 is moved to the closed position, the second lid member 142 overlaps in front of the protruding portion 132c of the first lid member 132. Thus, the further movement of the second lid member 142 toward the closed side is restricted. For this reason, even if the set value is illegally changed, the fact can be easily found.

  Since the guide groove 142e that supports the first lid member 132 so as to be slidable is provided in the second lid member 142, when the second lid member 142 is in the open position, the first lid member 132 is provided with the second groove 137b. The situation where it is supported so as to be slidable only by this occurs. Under such circumstances, when the first lid member 132 is moved to a position where the return plate portion 132b of the first lid member 132 and the cutout portion 137c of the second groove portion 137b coincide in the vertical direction, the first lid member 132 is moved. The first lid member 132 falls unless an upward external force is applied. Here, when the first lid member 132 is illegally moved from the gap between the housing 11 and the front door 12 using a wire or the like without opening the front door 12, the first lid member 132 is in the open position or Since it is difficult to grasp the position of the first lid member 132 except when it is in the closed position, an opportunity to drop the first lid member 132 can be generated. That is, if the setting is changed illegally, it is possible to leave a trace that the first lid member 132 is dropped. Therefore, it is possible to easily detect fraud.

  When the opening 142d of the second lid member 142 is positioned at the restriction release position, the return plate portion 132b and the notch 137c of the first lid member 132 are displaced in the vertical direction. Formed in position. For this reason, even when the hole manager or the like changes the setting, even when the first lid member 132 is moved to the restriction release position, the return plate portion 132b can be locked to the second groove portion 137b. Even if the second lid member 142 is rotated to the open side, the first lid member 132 can be prevented from falling.

  Since the reset switch 104 and the setting key switch 105 are directly mounted on the main board, a cable or the like for electrically connecting the main board and the reset switch 104 or a cable for electrically connecting the main board and the setting key switch 105 becomes unnecessary. . As a result, it is possible to prevent an unauthorized act of changing the setting by short-circuiting the cable or the like instead of operating the reset switch 104 or the setting key switch 105.

  Since the setting display unit 106 for displaying the setting value is provided only on the main board, the setting value cannot be confirmed unless the front door 12 is opened, and the front door 12 is opened from the housing 11. It is possible to make it difficult for the user to change the setting without any problem. The hall manager or the like changes the setting value desired by the hall manager or the like while checking the setting value displayed on the setting display unit 106 in order to perform the setting change operation after opening the front door 12 from the housing 11. On the other hand, the fraudster who changes the setting using a wire or the like cannot check the set value, and therefore cannot change the setting value desired by the fraudster. In addition, since the setting display unit 106 is directly mounted on the main board, a cable or the like for electrically connecting the setting display unit and the main board is not required. As a result, an illegal board or the like is electrically connected between the setting display section and the main board, and a setting value different from the actual setting value is displayed on the setting display section so that the hall manager or the like can exit the slot machine 10. It is possible to prevent fraud that misrecognizes the rate. Furthermore, it is possible to suppress not only the above-described frauds, ie, player-side frauds, but also frauds performed by the hall manager or the like on the players, ie, hall-side frauds. For example, even if the setting display unit is provided on the rear surface side of the front door 12, it is possible to make it difficult for the user to change the setting using a wire or the like. However, for example, when a hall manager or the like provides an illegal board or the like between the setting display unit and the main board and a setting value different from the actual setting value of the slot machine 10 can be displayed on the setting display unit, The player or the like may misrecognize the setting value of the slot machine 10 through the setting value displayed on the setting display unit, and may be forced to play a game with a lower rate than the player or the like assumes. On the other hand, in the configuration in which the setting display unit 106 is directly mounted on the main board, since the board box 110 is sealed, even the hole manager or the like cannot perform the fraud, and the player or the like is disadvantageous. Can be avoided.

  Since the setting display unit 106 is arranged in the vicinity of the reset switch 104 and the setting key switch 105, the hall manager or the like can perform a setting change operation without moving the line of sight so much. Therefore, the setting change operation can be facilitated. In addition, since the setting display unit 106, the reset switch 104, and the setting key switch 105 are centrally arranged on one side of the main board, even if the above-described members related to the setting change are directly mounted on the main board, the electronic components such as the CPU It is possible to suppress a decrease in the degree of design freedom regarding the arrangement. More specifically, the front door 12 is supported so as to be rotatable about the opening / closing axis of the left side of the housing 11, and the reset switch 104, the setting key switch 105, and the setting display unit 106 are on the right side of the main board, that is, Since it is provided on the open end side of the front door 12, the hall manager or the like can easily change the set value.

  Since the main controller 101 is disposed on the upper back side inside the housing 11, the distance from the front end of the housing 11, that is, the gap between the housing 11 and the front door 12, to the reset switch 104 and the setting key switch 105 can be increased. It becomes possible to make it difficult to operate the reset switch 104 and the setting key switch 105 using a wire or the like.

  The configuration of the present invention is not limited to the above-described embodiment (hereinafter referred to as the first embodiment), and various modifications can be made. For example, FIGS. 14 to 16 are diagrams for explaining another embodiment (hereinafter referred to as a second embodiment).

  FIG. 14A is a perspective view of a main part showing a case where the first lid member 132 and the second lid member 242 are in the closed position, and FIG. 14B shows that the first lid member 132 and the second lid member 242 are in the closed position. FIG. 15 and FIG. 16 are views for explaining the operation of the first lid member 132 and the second lid member 242 when they are in the open position. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The reset switch housing part 131 and the first lid member 132 have the same configuration as that of the first embodiment. The setting key switch accommodating portion 241 is formed with a pair of upper and lower bearing portions 247a and 247b on the left side wall portion, and the second lid member 242 is turnable in the left-right direction as in the first embodiment. Although it is pivotally supported, the setting key switch 105 is exposed when it is turned leftward, and the front side of the setting key switch 105 is covered when it is turned rightward. That is, the second lid member 242 is pivotally supported in the setting key switch accommodating portion 241 in the direction opposite to that of the first embodiment. The second lid member 242 and the lower bearing portion 247b are provided with coil springs (not shown) that urge the second lid member 242 toward the closed position.

  The second lid member 242 is made of a transparent synthetic resin material, and has a main body part 242a formed in a horizontally long rectangular flat plate shape, and a pair of left and right support shafts 242b formed on one side of the main body part 242a, 242c. An opening 242d that penetrates forward and backward and opens upward is formed in the upper portion of the main body 242a. As shown in FIG. 15B, the opening 242d has a shape that allows the protruding portion 132c of the first lid member 132 to be inserted back and forth. A guide groove 242e having a substantially L-shaped cross section extending in the left-right direction is formed on the front surface of the main body 242a so as to straddle the opening 242d. Closed wall portions 242f are formed at both left and right ends of the guide groove portion 242e, and the guide groove portion 242e has a shape that is open only upward except for a position corresponding to the opening portion 242d. On the rear surface of the main body 242a, shielding ribs are provided along the sides excluding the sides where the support shafts 242b and 242c are formed, the opening 242d, and the sides between the side and the opening 242d. 242g is formed. Further, a stopper portion 242h having a substantially L-shaped cross section extending in the left-right direction is formed on the rear surface of the main body portion 242a between the side portion where the support shafts 242b and 242c are formed and the opening portion 242d. The stopper portion 242h has a closed wall portion 242i formed at the end portion on the opening portion 242d side, and is open upward and leftward (opening and closing center side where the support shafts 242b and 242c are formed). .

  Here, since the mounting operation of the first lid member 132 and the second lid member 242 is the same as that of the first embodiment, the description thereof is omitted, and the operation when the lid members 132 and 242 are moved to the open position. explain.

  When both the lid members 132 and 242 are moved to the open position from the situation where both the lid members 132 and 242 are in the closed position (see FIG. 15A), the first lid member 132 is moved to the first lid member 132. The protrusion 132c and the opening 242d of the second lid member 242 are moved to the restriction release position where they overlap each other, and the restriction of the second lid member 242 by the protrusion 132c is released (see FIG. 15B). Then, the second lid member 242 is rotated leftward and moved to the open position (see FIG. 16A). Thereafter, with the second lid member 242 positioned and held at the open position, the first lid member 132 is moved to the open position, and the protruding portion 132c of the first lid member 132 is inserted into the stopper portion 242h of the second lid member 242. (See FIG. 16B). Under such circumstances, since the rotation of the second lid member 242 toward the closing side is restricted by the locking of the stopper portion 242h and the protruding portion 132c, the hole manager or the like resists the urging force of the coil spring. Even if the lid member 242 is not positioned and held at the open position, the lid members 132 and 242 can be positioned and held at the open position.

  In the second embodiment described in detail above, the following excellent effects are obtained in addition to the operational effects in the first embodiment described above.

  A stopper portion 242h is provided on the rear surface of the main body portion 242a of the second lid member 242, and when both the lid members 132 and 242 are in the open position, the protruding portion 132c of the first lid member 132 and the stopper portion 242h of the second lid member 242 are provided. It was set as the structure which latches. By adopting such a configuration, both the lid members 132 and 242 can be positioned and held at the open position while the first lid member 132 restricts the rotation of the second lid member 242 to the closing side, so that the set value is changed. It becomes possible to prevent the work at the time from becoming complicated.

  In addition, it is not limited to the description content of each embodiment mentioned above, For example, you may implement as follows.

  (1) In each of the above embodiments, the reset switch 104 and the setting key switch 105 are directly mounted on the main controller 101. However, the power switch 70 may be provided on the rear side of the front door 12. It is good also as a structure to provide. Even if it is a case where it is set as these structures, if it is set as the structure which covers the reset switch 104 and the setting key switch 105 with the 1st cover member and 2nd cover member which were mentioned above, there exists an effect similar to said each embodiment. Can do.

  (2) In each of the embodiments described above, the reset switch 104 and the setting key switch 105 are arranged so as to be lined up and down, but it goes without saying that they may be lined up side by side. When the first lid member is configured to be supported so as to be slidable up and down and the second lid member is configured to be supported so as to be capable of being pivoted up and down, The same operational effects as those of the respective embodiments can be obtained.

  (3) In the above embodiments, the first lid member 132 that covers the front side of the reset switch 104 restricts the movement of the second lid members 142 and 242 that cover the front side of the setting key switch 105 to the open side. However, the lid member that covers the front side of the setting key switch may be configured to restrict the movement of the lid member that covers the front side of the reset switch to the open side. For example, in the above embodiments, the arrangement of the reset switch 104 and the setting key switch 105 is switched. However, in such a configuration, when the slot machine 10 is returned from the error state, the lid member that covers the front side of the reset key is moved after the lid member that covers the front side of the setting key switch is moved to the restriction release position. Since the member must be moved to the open side, there is a concern that the work for returning from the error state may become complicated.

  (4) In each of the above embodiments, the first lid member 132 is configured such that the upper part of the main body part 132a and the lower part of the protruding part 132 are slidably supported. However, the present invention is not limited to such a structure. The part of the first lid member 132 that is supported so as to be slidable is arbitrary.

  (5) In the above embodiments, the openings 142d and 242d are formed in the second lid members 142 and 242, and the second lid members 142 and 242 are moved when the first lid member 132 is moved to the restriction release position. Although the configuration is such that the movement restriction to the open side is released, this configuration is changed. That is, instead of forming an opening in the second lid member, the extension wall portion and the second groove portion are extended to the left, and the first lid member and the second lid member do not overlap each other in the first and second positions. The lid member is configured to be slidable. Even in the case of such a configuration, if the first lid member is moved to the position, the movement restriction to the opening side of the second lid member is released, and thus the same effect as that of each of the above embodiments is obtained. Can play.

  (6) In each of the above embodiments, when the first lid member 132 is moved from the closed position to the open side, the second groove portion 137b restricts further movement to the open side. It is good also as a structure which is not performed. Specifically, the second groove part and the guide groove part of the second lid member have a shape opened to the left. In such a configuration, when the first lid member 132 is excessively pulled to the open side using a wire or the like, the locking of the return plate portion and the second groove portion of the first lid member is released. The locking of the protruding portion of the first lid member and the guide groove portion is released, and the first lid member falls. Therefore, as in the above-described embodiments, it is possible to leave a trace when fraud is made. In this case, when the first lid member is assembled, the return plate portion of the first lid member can be inserted from the left side of the second groove portion, so that the notch portion is not provided in the second groove portion. Good.

  (7) In each of the above embodiments, the guide groove portions 142e and 242e that support the first lid member 132 so as to be slidable are provided on the front side of the second lid members 142 and 242, but the second lid members 142 and 242 are provided. Needless to say, it may be provided on the rear side.

  (8) In the first embodiment, it goes without saying that a coil spring that biases toward the closing side may be provided on at least one of the first lid member 132 and the second lid member 142.

  (9) In each of the above embodiments, the reset switch 104 and the setting key switch 105 are directly mounted on the main control device 101, and when the front door 12 is opened from the housing 11, both the switches 104 and 105 can be seen from the front. This configuration is changed. That is, a reset switch and a setting key switch are provided on the rear surface side of the power supply box, and these switches are covered with the first lid member and the second lid member described above. In such a configuration, when a wire or the like is inserted from the gap between the housing and the front door, the wire or the like can be prevented from reaching both switches by the power supply box in addition to the both lid members. Therefore, it is possible to suitably suppress the setting from being illegally changed.

  (10) In each of the above embodiments, only the setting display unit 106 has a function of displaying the setting value. However, in addition to the setting display unit 106, for example, a function of displaying the setting value on the credit display unit 60 is provided. It is good also as a structure to provide. Even in the case of such a configuration, the regular setting value can be grasped by checking the setting value displayed on the setting display unit 106 directly mounted on the main board 102. It is possible to suppress fraud performed on players and the like. However, there is a concern that a fraudster who illegally changes the setting value may change the setting value desired by the fraudster while confirming the setting value displayed on the credit display unit 60. For this reason, when it is set as the structure which provides another member in addition to a main board | substrate, it is desirable to provide a setting display part in the inside of a housing | casing or the rear surface of a front door.

  (11) In each of the above embodiments, the setting display unit 106 is provided on the front right side of the main board 102. However, the setting display unit 106 may be provided on the front left side or the front center. Arrangement positions are arbitrary.

  (12) In each of the above embodiments, when the power is turned on while the setting key switch 105 is ON, the forced RAM clear process is performed to set the setting value to “1”. The configuration may be such that the static RAM clear processing is not performed, or the data other than the set value is cleared by the forced RAM clear processing.

  (13) In each of the above embodiments, the setting value is updated by one each time the reset switch 104 is operated. However, the present invention is not limited to such a configuration, and the setting value is updated at random. A configuration may be used, or a setting value may be automatically updated every predetermined time, and a setting value may be determined by operating the reset switch 104 when a setting value desired by a hall manager or the like is displayed. .

  (14) In each of the above-described embodiments, a specific example of the slot machine 10 has been described. However, the present invention is applied to a pachinko machine that has a plurality of winning probabilities and can change the winning probability by performing a setting change operation. Alternatively, it may be applied to a gaming machine of a type in which a slot machine and a pachinko machine are fused.
