A first sealing member 120 for sealing the substrate box 110 is provided in each of the box cover 111 and the box case 112 at the center left portion of the first opening hole portion 118 and the center right portion of the second opening hole portion 119. It has been. Briefly describing the sealing, when a sealing pin is inserted into the first sealing member 120 of the box cover 111 and the box case 112, the box base 111 and the box cover 112 are coupled so as not to be opened. When the main board 102 is taken out from the board box 110, the first sealing member 120 with the sealing pin inserted is cut from the box cover 111 and the box case 112, so that the box base 111 and the box cover 112 are joined. Is released. That is, when the main substrate 102 is taken out of the substrate box 110, the cut traces of the first sealing member 120 remain on the box base 111 and the box cover 112. Therefore, if a history of opening the board box 110 is left on the hall side, it is possible to easily find out that the board box 110 has been illegally opened by checking the board box 110. In the first opening hole 118 and the second opening hole 119 of the box case 112, two second sealing members 121 for sealing the main control device 101 to the pedestal device 151 are provided.

  Here, the configuration of the reset switch housing part 131, the setting key switch housing part 141, and the both lid members 132 and 142 provided in the box cover 111 will be described in more detail.

  The reset switch housing part 131 has a bottom plate part 133 extending in parallel with the main substrate 102, and has a slightly larger outer diameter than the operation part 104 c of the reset switch 104 at a position corresponding to the reset switch 104 of the bottom plate part 133. An opening hole 133a is formed. 10A, in a state where the main board 102 is accommodated in the board box 110, the operation part 104c protrudes forward from the bottom plate part 133. More specifically, the rear end of the operation part 104c is the bottom plate. The front end of the operation unit 104c is positioned in front of the front surface of the bottom plate 133 while being positioned rearward of the front surface of the unit 133. A cylindrical covering wall portion 134 is integrally formed at the outer peripheral edge portion of the opening hole 133 a so as to cover the periphery of the reset switch 104. The covering wall portion 134 includes a first covering wall portion 134 a that protrudes forward from the bottom plate portion 133 and a second covering wall portion 134 b that protrudes rearward from the bottom plate portion 133. As shown in FIG. 10A, the first covering wall portion 134a is in a state where the reset switch 104 is not pushed from the front surface of the bottom plate portion 133 (hereinafter, the reset switch 104 in the state is said to be in the initial position). ), The front and back dimensions are shorter than the distance to the front end of the operation portion 104c. In this situation, the front end of the first covering wall portion 134a is located slightly behind the front end of the operation portion 104c. Further, as shown in FIG. 10B, the second covering wall portion 134b is in a state in which the reset switch 104 is pushed from the rear surface of the bottom plate portion 133 (hereinafter, the reset switch 104 in the state is in the post-operation position). The front and rear dimensions are longer than the distance to the tip of the operation portion 104c. That is, the covering wall portion 134 is formed such that at least a part of the operation portion 104c is positioned inside the covering wall portion 134 regardless of the displacement state of the operation portion 104c.

  Further, the reset switch housing part 131 has a rectangular frame-shaped wall part 135 that is formed to stand forward from the peripheral edge part of the bottom plate part 133. The wall 135 has a front-rear dimension whose front end is positioned forward of the front end of the operation unit 104 c of the reset switch 104. A plurality of reinforcing ribs 136 are formed on the upper side wall portion and the lower side wall portion of the wall portion 135 on the reset switch 104 side, that is, inside the reset switch housing portion 131. The reinforcing rib 136 is formed along the corresponding wall portion from the bottom plate portion 133 and has a slightly shorter front-rear dimension than the wall portion. More specifically, the longitudinal dimension of the reinforcing rib 136 is obtained by subtracting the thickness dimension of the first lid member 132 from the longitudinal dimension of the corresponding wall portion. A concave portion is formed in the central portion of the right side wall portion of the wall portion 135, and a pair of upper and lower bearing portions 137a and 137b are formed so as to sandwich the concave portion. Further, a shielding wall portion 138 for preventing a wire or the like from being inserted into the reset switch housing portion 131 from the recessed portion is formed on the right side of the covering wall portion 134 at a position corresponding to the recessed portion. . The left side wall portion of the wall portion 135 has a shorter front-rear dimension than the surrounding wall portion. Specifically, the front-rear dimension of the left side wall portion is the same as the front-rear dimension of the reinforcing rib 136 obtained by subtracting the thickness dimension of the first lid member 132 from the front-rear dimension of the surrounding wall portion.

  A first lid member 132 is rotatably attached to the front surface side of the reset switch housing portion 131. The first lid member 132 is made of a transparent synthetic resin material, and has a main body part 132a formed in a horizontally long rectangular flat plate shape, and a pair of upper and lower support shafts 132b formed on one side of the main body part 132a. 132c. When the support shafts 132b and 132c are inserted in the bearing portions 137a and 137b, the first lid member 132 is an open / close axis extending in the vertical direction connecting the support shafts 132b and 132c to the reset switch housing portion 131. The front opening side of the reset switch housing 131 can be opened or closed by the rotation of the first lid member 132. 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. When the first lid member 132 is in the closed position, the rear surface of the main body portion 132a of the first lid member 132 is in contact with the front end surface of the reinforcing rib 136 and the front end surface of the left side wall portion of the reset switch housing portion 131. The front surface of the portion 132a and the tip surfaces of the upper and lower side wall portions are located on the same plane. On the rear surface of the main body portion 132a of the first lid member 132, a U-shaped shielding rib 132d that opens toward the support shafts 132b and 132c is formed. When the first lid member 132 is in the closed position, the shielding rib 132d is inward of the reinforcing rib 136 of the reset switch housing portion 131 and contacts the side surface of the reinforcing rib 136 facing the reset switch 104 in the vertical direction. Formed in position. A coil spring 139 that biases the first lid member 132 toward the closed position is provided on the lower support shaft 132c of the first lid member 132 and the lower bearing portion 137b of the right side wall portion.

  The setting key switch accommodating portion 141 has a bottom plate portion 143 extending in parallel with the main substrate 102, and is slightly larger than the key cylinder portion 105b of the setting key switch 105 at a position corresponding to the setting key switch 105 of the bottom plate portion 143. An opening hole 143a having an outer diameter is formed. As shown in FIG. 9, the key cylinder portion 105 b protrudes forward from the bottom plate portion 143 when the main substrate 102 is accommodated in the substrate box 110. A cylindrical covering wall portion 144 protruding rearward from the bottom plate portion 143 is formed on the outer peripheral edge portion of the opening hole 143a. The covering wall portion 144 has a front-rear dimension in which the tip thereof is close to the tip of the base portion 105 a of the setting key switch 105. Thus, unlike the reset switch housing part 131, the setting key switch housing part 141 is not provided with a covering wall part protruding forward from the bottom plate part 143.

  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. The wall portion 145 has a front-rear dimension in which the front end is a front position from the front end of the setting key switch 105. Further, in the present embodiment, the reset switch 104, the setting key switch 105, the reset switch housing 131, and the reset switch housing 131 are commonly used as the upper wall of the setting key switch housing 141. The setting key switch accommodating portion 141 is centrally arranged. 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 at the central portion of the left 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. Also, a shielding wall 148 is formed on the left side of the setting key switch 105 at a position corresponding to the recess to prevent a wire or the like from being inserted into the setting key switch housing 141 from the recess. Yes. The right 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 right 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 portion 142a formed in a horizontally long rectangular flat plate shape, and a pair of upper and lower support shafts 142b formed on one side of the main body portion 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. 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 right 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. On the rear surface of the main body 142a of the second lid member 142, U-shaped shielding ribs 142d that open to the support shafts 142b and 142c are formed. When the second lid member 142 is in the closed position, the shielding rib 142d is 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. A coil spring 149 that urges the second lid member 142 toward the closed position is provided on the support shaft 142b on the upper side of the second lid member 142 and the bearing portion 147a on the upper side of the left side wall portion.

  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 second lid member 142 is rotated leftward from the closed position to move to the open position, and 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 rotated rightward from the closed position to move 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, and 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. In addition, since the first lid member 132 and the second lid member 142 are provided with coil springs 139 and 149 that are biased toward the closed position side, when the hall manager or the like finishes the above operation, the hall manager Even if the lid members 132 and 142 do not move the lid members 132 and 142 to the closed position, the lid members 132 and 142 move to the closed position, and the front surfaces of the reset switch 104 and the setting key switch 105 are covered.

  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 turned ON, the data in the RAM 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 finished (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 102, and the first lid member 132 and the second lid member 142 are arranged adjacent to each other. Can be suppressed.

  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.

  Coil springs 139 and 149 for urging the first lid member 132 and the second lid member 142 toward the closed position are provided. In such a configuration, since it becomes necessary to operate the reset switch 104 and the setting key switch 105 while urging the lid members 132 and 142 toward the open position, the fraudulent acts the lid members 132 and 142 at the open position. It is necessary to insert a wire or the like for maintaining and a wire or the like for operating the reset switch 104 and the setting key switch 105. Therefore, it is possible to make it difficult to change the setting without opening the front door 12 from the housing 11 or slightly opening it. Moreover, since it becomes necessary to insert more wires or the like through the gap between the housing 11 and the front door 12, it becomes possible to easily find the fraud. Further, after the hall manager or the like changes the set value, the lid members 132 and 142 are moved to the closed position by the bias of the coil springs 139 and 149, so that the hall manager or the like moves the lid members 132 and 142 to the closed position. It is possible to prevent an unauthorized act of changing the setting from being a result of forgetting to move to.

  When the first lid member 132 is in the closed position, the front surface of the main body portion 132a of the first lid member 132 and the distal end surfaces of the upper and lower side walls of the reset switch housing portion 131 are located on the same plane, and the second lid When the member 142 is in the closed position, the front surface of the main body portion 142a of the second lid member 142 and the front end surfaces of the upper and lower wall portions of the setting key switch 141 are located on the same plane. As described above, the front surfaces of the lid members 132 and 142 are positioned on the same plane as the front end surfaces of the corresponding accommodating portions 131 and 141, so that, for example, one wire or the like is first from above the reset switch accommodating portion 131. The wire is inserted into the gap between the lid member 132 and the reset switch housing part 131 and the wire or the like is further inserted into the gap between the second lid member 142 and the setting key switch housing part 141 so that both the lid members 132 and 142 are moved to the open position side. It is possible to suppress illegal movement. In addition, since the shielding ribs 132d and 142d are provided on the rear surfaces of the lid members 132 and 142, one wire or the like is formed between the first lid member 132 and the reset switch housing portion 131, and the second lid member 142 and the setting key switch housing portion. It can be made more difficult to insert into the gap 141.

  Since the reset switch 104 and the setting key switch 105 are directly mounted on the main board 102, there are cables that electrically connect the main board 102 and the reset switch 104, cables that electrically connect the main board 102 and the setting key switch 105, and the like. It 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 102, 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 to cheat changing the settings without doing so. 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. Further, since the setting display unit 106 is directly mounted on the main board 102, a cable or the like for electrically connecting the setting display unit and the main board 102 is not necessary. As a result, an illegal board or the like is electrically connected between the setting display section and the main board 102, 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 It is possible to prevent fraud that misrecognizes the outgoing 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 102 and a setting value different from the actual setting value of the slot machine 10 can be displayed on the setting display unit, A 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 assumes. On the other hand, in the configuration in which the setting display unit 106 is directly mounted on the main board 102, since the board box 110 is sealed, even the hole manager or the like cannot perform the above fraud, and the player or the like is not allowed. Problems that incur profits 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 102, even if each of the members related to the setting change is directly mounted on the main board 102, an electronic device such as a CPU. It is possible to suppress a decrease in the degree of design freedom regarding the arrangement of components. Further, 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 arranged on the right side of the main board 102. That is, since it is provided on the open end side of the front door 12, a hall manager or the like can easily change the set value.

  Since the main control device 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 reset switch housing portion 131 and the setting key switch housing portion 141 are provided with a second covering wall portion 134b and a covering wall portion 144 that protrude rearward from the bottom plate portions 133 and 143 at the outer peripheral edge portions of the opening holes 133a and 143a. . By adopting such a configuration, it is possible to cheat on the IC chip or the like mounted on the main board 102 from the opening holes 133a and 143a while suppressing the occurrence of problems such as an increase in the defect rate of the box cover 111. This can be suppressed.

  Certainly, in the configuration in which the opening holes 133a and 143a communicating with the main board 102 are provided in the box cover 111, the diameters of the opening holes 133a and 143a are set to the outside diameter of the operation portion 104c of the reset switch 104 or the key cylinder portion 105b of the setting key switch 105. If it is made equal to the diameter, the gap between the opening hole 133a and the operation part 104c and the gap between the opening hole 143a and the key cylinder part 105b can be substantially eliminated, and the above-mentioned fraud can be suppressed. However, in such a configuration, due to molding variation, the diameter of the opening hole 133a is smaller than the outer diameter of the operation portion 104c, or the diameter of the opening hole 143a is smaller than the outer diameter of the key cylinder portion 105b, and the defect rate of the box cover 111 is reduced. There is concern about the possibility of an increase. Further, there is a concern that the operation unit 104c and the opening hole 133a may be rubbed and worn or damaged when the reset switch 104 is pushed. On the other hand, in the configuration in which the second covering wall portion 134b and the covering wall portion 144 are provided, for example, even if a wire or the like is inserted from the gap between the opening hole 133a and the operation portion 104c, the wire or the like is moved by the second covering wall portion 134b. Movement to the center side of the main board 102 can be restricted, and fraud to the main board 102 can be made difficult. Further, in the opening hole 143a on the setting key switch 105 side, even if a wire or the like is inserted from the gap between the opening hole 143a and the key cylinder part 105b, the wire or the like is moved to the center side of the main substrate 102 by the covering wall part 144. Further movement to the main board 102 side can be restricted by the base portion 105a of the setting key switch 105 while restricting this, and fraud with respect to the main board 102 can be made difficult. As described above, by providing the second covering wall portion 134b and the covering wall portion 144, it becomes possible to give a margin to the dimensional accuracy of the opening holes 133a and 143a while making it difficult to cheat the main substrate 102. It is possible to suppress the occurrence of problems such as an increase in the defect rate of the box cover 111.

  In addition, the reset switch housing part 131 is provided with the first covering wall part 134a projecting forward from the bottom plate part 133 at the outer peripheral edge part of the opening hole 133a, so that it is more difficult to cheat the main board 102. It becomes possible. The distance from the front end surface of the covering wall portion 134 to the main substrate 102 (that is, the distance from the position where the wire or the like is inserted to the main substrate 102) can be increased, and the length of the covering wall portion 134 in the front-rear direction can be increased. This is because it becomes difficult to incline the wire or the like toward the center of the main substrate 102 as the length increases. Further, by providing the first covering wall portion 134a, the distance from the front end surface of the covering wall portion 134 to the rear end of the operation portion 104c can be increased, and the gap between the covering wall portion 134 and the reset switch 104 becomes large. It is difficult to insert a wire or the like up to the portion 104b and make the wire or the like reach the center side of the main substrate 102 using the gap. Furthermore, when the reset switch 104 is in the post-operation position as in the present embodiment, the first covering wall portion 134a is not provided in the configuration in which the distal end of the operation portion 104c is located behind the front surface of the bottom plate portion 133. Then, by pressing the reset switch 104, the operation unit 104c is moved rearward from the front surface of the bottom plate 133, and the wire is inserted so as to allow the wire to reach the IC chip while ensuring a wide space around the opening hole 133a. There is concern about cheating. On the other hand, in the configuration in which the first covering wall part 134a is provided, even if the reset switch 104 is moved to the post-operation position, it is possible to prevent the first covering wall part 134a from securing a space around the opening hole 133a. The above concerns can be resolved.

  Since the first covering wall portion 134a has a configuration in which the front end of the first covering wall portion 134a is slightly rearward from the front end of the operation portion 104c of the reset switch 104 when the reset switch 104 is in the initial position, The portion 104c may be difficult to be removed from the body portion 104b or the base portion 104a, and the operation portion 104c is removed from the body portion 104b or the base portion 104a, and then the body portion 104b or the base portion 104a is connected to the first portion. It is possible to suppress fraud in which a wire or the like is inserted from the gap between the covering wall portions 134a. In addition, the operability of the reset switch 104 can be ensured. If the first covering wall portion 134a has a front-rear dimension that is in front of the front end of the operation portion 104c of the reset switch 104, the finger of a hole manager or the like interferes with the first covering wall portion 134a and the operation portion 104c. This is because there is a possibility that the button cannot be operated.

  When the reset switch 104 is in the post-operation position, the second covering wall portion 134b has a front-rear dimension in which the rear end of the second covering wall portion 134b is located behind the front end of the operation portion 104c. With this configuration, at least a part of the operation unit 104c can be positioned inside the covering wall unit 134 regardless of the displacement state of the operation unit 104c. Therefore, the operation part 104c is pushed from the rear end of the second covering wall part 134b to the rear to create a large gap, thereby preventing an illegal act of inserting a wire or the like from the gap.

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

  (1) In the above embodiment, the second covering wall portion 134b protruding rearward from the bottom plate portion 133 is provided on the outer peripheral edge portion of the opening hole 133a of the reset switch housing portion 131. However, the second covering wall portion 134b may be omitted. That is, only the first covering wall portion 134a protruding forward from the bottom plate portion 133 is provided. Even in such a configuration, it is possible to give a margin to the dimensional accuracy of the opening hole 133a while making it difficult to cheat the main substrate 102, and the defect rate of the box cover 111 is increased. Can be prevented from occurring. However, with such a configuration, when the reset switch 104 is in the post-operation position, the distal end of the operation portion 104c is positioned in front of the bottom plate portion 133 (that is, in front of the base end of the first covering wall portion 134a). It is desirable to do.

  (2) In the above embodiment, when the reset switch 104 is in the initial position, the tip end of the first cover wall portion 134a is slightly behind the tip end of the operation portion 104c of the reset switch 104. Although the configuration has the front-rear dimension, the front end of the first covering wall portion 134a may have a front-rear dimension in which the front end is positioned ahead of the front end of the operation portion 104c of the reset switch 104.

  (3) In the above embodiment, the second covering wall portion 134b is formed in a cylindrical shape, that is, over the entire circumference of the opening hole 133a, but may be formed only on the side where the IC chip is mounted. Even in such a configuration, it is possible to restrict the wire or the like from reaching the IC chip by the second covering wall portion, and it is possible to suppress frauds made to the main substrate 102. .

  (4) In the above embodiment, the covering wall portion 134 is integrally formed with the box cover 111. However, the covering wall portion may be attached and fixed to the outer peripheral edge portion of the opening hole 133a. Even if it is a case where it is set as this structure, there can exist an effect similar to the said embodiment. However, in such a configuration, it is desirable to fix the covering wall portion so that it cannot be removed, or to fix the trace when it is removed.

  (5) In the above embodiment, the configuration in which both the first lid member and the second lid member are pivotally supported is described. However, the present invention is not limited to such a configuration, and is supported so as to be slidable. It is good also as the structure currently made.

  (6) Although the first lid member 132 that covers the front of the reset switch 104 is provided in the above embodiment, it may not be provided.

  (7) In the above embodiment, the reset switch 104 is provided on the front right side of the main board 102. However, the reset switch 104 may be provided on the front left side or the front center. Arrangement positions are arbitrary. However, in consideration of the possibility of inserting a wire or the like from the opening hole, the reset switch 104 is preferably provided on one side of the front side of the main board 102.

  (8) In the above embodiment, 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. Alternatively, the setting value may be automatically updated every predetermined time, and the setting value may be determined by operating the reset switch 104 when the setting value desired by the hall manager or the like is displayed.

  (9) In the above embodiment, the setting key switch accommodating portion 141 is not provided with the covering wall portion protruding forward from the bottom plate portion 143, but it goes without saying that it may be provided.

  (10) In the above embodiment, the configuration in which the reset switch 104 that is operated when the set value is changed and when the error state is restored is directly mounted on the main board 102. However, when the set value is changed. A cover wall portion may be provided in a configuration in which a switch that is operated only on the main board 102 is directly mounted, or in a configuration in which a switch that is operated only when returning from an error state is directly mounted on the main board 102 It is good also as a structure which provides a part.

  (11) In the above embodiment, the configuration in which the reset switch 104 is directly mounted on the main board 102 and the covering wall portion 134 is provided has been described. However, the display control device 81 is pressed when, for example, changing the display effect. It is good also as a structure which directly mounts an operation part and provides a coating | coated wall part. Even if it is a case where it is set as this structure, there can exist an effect similar to the said embodiment.

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

  (13) In the above embodiment, an example of the slot machine 10 is shown. However, the present invention is applied to a pachinko machine having a control device in which an operation unit whose internal state is changed when a push operation is performed is directly mounted. Alternatively, the present invention may be applied to a gaming machine in which a slot machine and a pachinko machine are combined.
