  In the reel rotation processing, the CPU 101 rotates each of the reels R1 to R3 by continuously supplying pulses to each of the stepping motors 54a to 54c. When the CPU 101 receives an operation of the stop button 13 while the reel R is rotating, the CPU 101 stops the rotation of the reel R. When the winning of any combination is determined by the internal lottery process, the CPU 101 stops the reel R so that the symbol related to the winning combination is drawn on the winning line L1.

  The CPU 101 performs a winning determination process when all of the reels R1 to R3 are stopped. When it is determined that the winning combination is won by the winning determination process, the CPU 101 executes a process according to the winning combination such as a medal payment process. On the other hand, if the CPU 101 determines that a small role has not been won by the winning determination process, or after executing the medal payment process, the process related to one game is terminated.

  The display control board 100B has an instruction function. The instruction function is to notify the player of the operation mode such as the operation order and operation timing of the stop button 13 in a special gaming state. This is realized by the CPU 191 receiving the result of the internal lottery process from the CPU 101 and causing the liquid crystal display device 30 to display the operation mode of the stop button 13 determined based on the result of the internal lottery process. In a special gaming state, the player can reliably win a winning combination or the like won by the internal lottery process by operating the stop button 13 in accordance with the notified operation mode.

And a concave portion 352 formed as a hole penetrating the lid-side convex portion 351. Thereby, when the box side recessed part 311 and the lid side convex part 351 are engaged, the convex part 312a and the convex part 312b are fitted into the concave part 352, respectively, so that the box side concave part 311 and the lid side convex part 351 are fitted. The state of engagement with becomes stronger.

  In addition, since the concave portion 352 included in the lid-side convex portion 351 is formed as a through hole, when the box-side concave portion 311 and the lid-side convex portion 351 are engaged, the adhesive of the box-side concave portion 311 Since it flows inward, it can prevent that an adhesive agent leaks to the exterior of the box side recessed part 311 and the cover side convex part 351. FIG.

  The width w1 of the lid-side convex portion 351 is larger than the interval w2 between the tip of the convex portion 312a and the tip of the convex portion 312b. For this reason, when the lid side convex part 351 is engaged with the box side concave part 311, the outer wall 311a and the inner side wall 311b of the box side concave part 311 formed in a concave shape are curved outward. In the box-side recess 311, the thickness of the width w5 of the outer wall 311a in the vicinity of the portion having the convex portion 312a is thinner than the thickness of the width w3 of the outer wall 311a in the vicinity of the portion not having the convex portion 312a.

As shown in FIG. 9B, the lid-side convex portion 351 may include a convex portion 352c and a convex portion 352d formed in a convex shape on both side surfaces thereof. Moreover, you may form the recessed part 312c and recessed part 312d which were formed as a through-hole in each of the outer side wall 311a and the inner side wall 311b of the box side recessed part 311. In this case, when the box-side concave portion 311 and the lid-side convex portion 351 are engaged, the concave portion 312c is fitted into the convex portion 352c, and the concave portion 312d is fitted into the convex portion 352d.

(3) Modification 3
In each form mentioned above, although the structure provided with a recessed part or a convex part in the both sides | surfaces of the lid side convex part 351 was illustrated, it is not restricted to this. Although illustration is omitted, for example, a concave portion or a convex portion is provided only on one side of the lid side convex portion 351, and the concave portion or the convex portion is provided only on one side of the outer side wall 311a or the inner side wall 311b of the corresponding portion of the box side concave portion 311. You may make it provide a convex part. Thus, the form of each shape formed in order to make the engagement between the box-side concave portion 311 and the lid-side convex portion 351 stronger may be appropriately modified.

(4) Modification 4
In each of the embodiments described above, each of the box-side recess 311 included in the box member 310 and the lid-side protrusion 351 included in the lid member 350 is bonded to the box case 310 and the lid member 350 so that the substrate case 300 is the display control board. Although an example of a configuration in which the outer periphery of the display control board 100B is surrounded continuously when the 100B is housed therein is illustrated, the present invention is not limited to this. For example, when the box member 310 and the lid member 350 are joined, the box-side concave portion 311 and the lid-side convex portion 351 may be configured at a plurality of locations that surround the outer periphery of the display control board 100B.

(5) Modification 5
In each form mentioned above, although the box member 310 and the cover member 350 which comprise the substrate case 300 illustrated the structure which uses transparent polycarbonate resin, it is not restricted to this. For example, the box member 310 and the lid member 350 may be made of other materials, or may be made of a translucent or opaque material.

(6) Modification 6
In each of the above-described embodiments, the configuration in which the substrate case 300 stores the display control substrate 100B inside is illustrated, but the present invention is not limited to this. For example, the control board accommodated in the board case 300 may be the main control board 100A or another control board.

  In each form mentioned above, although the cover member 350 illustrated the structure which forms locations other than the location in which the cover side convex part 351 is formed as thickness h1, it is not restricted to this. FIG. 10A is a front view of a lid member 350 having a thin portion 355 and a seam portion 355a when viewed from directly above the bonding direction with respect to the box member 310. FIG. The thin portion 355 is continuously formed on the inner side of the lid-side convex portion 351 formed on the inner periphery of the inner surface of the box member 310. The thin portion 355 is formed at a position corresponding to a plurality of air holes (not shown) provided in the box member 310 in a state where the box member 310 and the lid member 350 are joined. Moreover, the thin part 355 has the seam part 355a formed in the semicylindrical shape in several places.

  FIG. 10B is a cross-sectional view taken along the line CC in FIG. The thin portion 355 is formed with a thickness h2 that is thinner than the thickness h1 of the lid member 350. Further, the vicinity of the apex of the semi-cylindrical joint portion 355a is formed with a thickness substantially the same as the thickness h1 of the lid member 350. Accordingly, when the lid member 350 is to be peeled from the substrate case 300 by intruding the rod-shaped member into the air hole of the box member 310 from the outside of the box member 310 and pressing the lid member 350 from the inside. Since the rod-shaped member breaks the thin part 355 and penetrates with a weaker force than the box member 310 and the lid member 350 which are joined by the engagement between the box-side concave portion 311 and the lid-side convex portion 351 are peeled off. Further, the lid member 350 cannot be peeled from the substrate case 300.

  The reason why the thin portion 355 has the plurality of joint portions 355a is that a bypass path for improving the flow of the resin at regular intervals is provided in a mold for molding the lid member 350. In the present invention, the seam portion 355a is formed in a semi-cylindrical shape. Thereby, even when the rod-shaped member is inserted from the vent so as to press the joint portion 355a, the rod-shaped member slides down the joint portion 355a and reaches the thin portion 355. Since the thin portion 355 is broken and penetrated, the lid member 350 cannot be peeled off from the substrate case 300.

  The thin portion 355 of the lid member 350 may be formed at a position that does not correspond to the hole provided in the box member 310 in a state where the box member 310 and the lid member 350 are joined. In this case, a position where the rod-shaped member that has entered from the hole of the box member 310 breaks part of the lid member 350 with a weaker force than the adhesive force of the adhesive in the box-side concave portion 311 and the lid-side convex portion 351. In addition, the thin portion 355 in the lid member 350 may be formed. As a result, even when the substrate case 300 is opened by the rod-shaped member that has entered from the hole of the box member 310 destroying a part of the lid member 350, the destruction trace remains, and thus the control board is illegal. Acts can be easily discovered.
