  However, the sub-control board 21 and the main control board 76 have unit structures individually housed in a hard plastic protective case.

  In the slot machine 1 configured as described above, the mini main reel device 20 includes a case 22 having an upper case portion 23 and a lower case portion 30 that can be divided into upper and lower parts, as shown in FIG. The reel unit includes three reel units 40, 40 ′, and 40 ″ that rotatably support the reels MR1, MR2, and MR3 arranged side by side. The three reel units 40, 40 ′, 40 ″ have the same structure. Therefore, the reel unit 40 will be described, and the description of the other reel units 40 ′ and 40 ″ will be omitted.

  The reel unit 40 includes a reel MR1 and a support member 41 that rotatably supports the reel MR1. As shown in FIGS. 4A and 4B, the reel MR <b> 1 includes a skeleton-like frame body 43 and a stepping motor SM that rotates the frame body 43. The frame 43 is constituted by connecting a plurality of bridge piers 43b between the peripheral portions of a pair of annular portions 43a arranged to face each other. A disc-shaped base 43c is disposed at the center of one annular portion 43a, and a plurality of radially extending arms 43d are connected between the base 43c and the annular portion 43a.

The relay shaft 44, the relay member 45, and the stepping motor SM are arranged inside the frame body 43 from the base portion 43c, and the screw 46 inserted through the relay shaft 44 and the relay member 45 from the base portion 43c is the shaft portion SM _{1 of the} stepping motor SM. And the stepping motor SM is fixed to the base 43c. Then, as shown in FIG. 5, the base end side end portion of the stepping motor SM protrudes outward from the side surface of the other annular portion 43a and extends along the side surface of the other annular portion 43a. It is fixed to the member 41. That is, the reel MR1 is rotatably supported by the support member 41 via the relay shaft 44, the relay member 45, and the stepping motor SM. For this reason, when the stepping motor SM is driven, the reel MR1 rotates with respect to the support member 41.

  As shown in FIG. 3, the support member 41 is made of sheet metal, extends in the vertical direction, has a substantially rectangular shape in a side view, and a main body portion 41 a that covers the side surface of the reel MR <b> 1 and a protruding portion 41 b that protrudes rearward therefrom. It has. Inclined portions 41c are formed at both front and lower end portions on the front side of the main body portion 41a. The inclined portions 41c are formed on the bottom plates 33 on the front side of the upper case portion 23 and the lower case portion 30. The engaged groove portion 31 is engaged. The rear end of the projecting portion 41b extends in a substantially vertical direction and engages with the first guide groove portion 32 and the second guide groove portion 24 formed in the respective rear plates 35 of the lower case portion 30 and the upper case portion 23.

  A flange portion 41d that protrudes toward the reel MR1 is formed at the front lower portion and the rear upper portion of the main body portion 41a. The flange portion 41 d is disposed at a position in contact with the inner surface of the bottom plate 33 of each case portion 30, 23 in a state where the reel unit 40 is accommodated between the lower case portion 30 and the upper case portion 23. The flange portion 41d is provided with a female screw 41e. When a male screw (not shown) inserted through the lower case portion 30 is tightened into the female screw 41e of the lower flange portion 41d, the lower portion of the support member 41 can be fixed to the lower case portion 30 and the upper case portion 23 is fixed. When the inserted male screw (not shown) is fastened to the female screw 41e of the upper flange portion 41d, the upper portion of the support member 41 can be fixed to the upper case portion 23. For this reason, the reel MR <b> 1 can be firmly fixed to the case 22 via the support member 41.

  Moreover, since the upper case part 23 and the lower case part 30 are connected by the support member 41, the rigidity of the case 22 in the vertical direction can be improved. As a result, the upper case portion 23 and the lower case portion 30 do not require ribs or the like for improving the rigidity in the vertical direction, and the structures of the upper case portion 23 and the lower case portion 30 can be simplified. Detailed structures of the upper case portion 23 and the lower case portion 30 will be described later. Since the support member 41 is made of sheet metal, the heat generated from the stepping motor SM described above can be radiated through the support member 41.

  The lower case portion 30 of the case 22 that accommodates the reel unit 40 configured as described above includes a bottom plate 33 that extends in the front-rear direction, a pair of side plates 34 that extend upward from the left and right ends of the bottom plate 33, and the rear end portions of the bottom plate 33. And a rear plate 35 connected to the rear end portions of the pair of side plates 34 and formed in a box shape. The inner space of the lower case portion 30 is surrounded by a bottom plate 33, a pair of side plates 34, and a rear plate 35 to form a receiving portion 36 that can receive the lower portions of the three reel units 40, 40 ′, 40 ″. . The housing portion 36 is open on the upper side and the front side.

  On the front upper surface of the bottom plate 33, the above-described engaging groove portion 31 is formed which is arranged with a predetermined interval in the left-right direction and extends in the front-rear direction. The engaging groove portion 31 has substantially the same length as the inclined portion 41 c below the support member 41 and extends. Accordingly, when the lower inclined portion 41 c is engaged with the engagement groove portion 31, the front lower portion of the support member 41 can be positioned.

  The inner surface of the rear plate 35 is provided with the first guide groove portion 32 described above that is arranged with a predetermined interval in the left-right direction and extends in the up-down direction. The first guide groove portion 32 is formed by a space portion between two projecting pieces 32 a that project at a predetermined interval in the left-right direction of the inner surface of the rear plate 35. The 1st guide groove part 32 is arrange | positioned in the substantially same position in the left-right direction as the engagement groove part 31 corresponding to this. For this reason, when the protruding portion 41 b of the support member 41 extending linearly is engaged with the first guide groove portion 32, the lower inclined portion 41 c of the support member 41 can be easily engaged with the engagement groove portion 31. . The first guide groove portion 32 extends from the lower portion to the upper end of the inner surface of the rear plate 35, and has a length that is substantially half of the vertical length of the protruding portion 41 b of the support member 41. For this reason, when the lower side of the protrusion 41b is inserted downward from the upper end of the first guide groove 32 and the lower end of the support member 41 contacts the upper surface of the bottom plate 33, the substantially lower half of the protrusion 41b is moved to the first. The guide groove 32 can be engaged. Thereby, the lower side of the protrusion 41b is securely held and positioned.

  Furthermore, the dimension (width dimension) of the left-right direction of the 1st guide groove part 32 has a magnitude | size which fits the protrusion part 41b so that positioning is possible. That is, the gap between the two when the lower portion of the protruding portion 41b is inserted into the first guide groove portion 32 is designed to be small. For this reason, if the protrusion part 41b is inserted in the 1st guide groove part 32, the protrusion part 41b can be attached to the 1st guide groove part 32 without backlash.

  A flange portion 34a extending outward in the left-right direction is formed on each upper portion of the pair of side plates 34, and a plurality of fixing holes 34b are provided in each flange portion 34a.

  The upper case part 23 arranged to face the lower case part 30 configured as described above has a shape substantially similar to that of the lower case part 30. For this reason, about the upper case part 23, only the part which is different from the lower case part 30 is demonstrated, about the same aspect part as the lower case part 30, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  On the inner surface of the rear plate 35 of the upper case portion 23, the above-described second guide groove portion 24 that is disposed with a predetermined interval in the left-right direction and extends in the up-down direction is provided. The second guide groove portion 24 is disposed at a position communicating with the first guide groove portion 32 when the flange portions 34a of the lower case portion 30 and the upper case portion 23 are joined in a state of being opposed to each other. Accordingly, the upper side of the protruding portion 41 b of the support member 41 inserted into the first guide groove portion 32 can be inserted into the second guide groove portion 24.

  Here, the width dimension of the second guide groove portion 24 is larger than that of the first guide groove portion 32. For this reason, the insertion of the upper part of the protrusion part 41b to the 2nd guide groove part 24 can be made easy. The width of the second guide groove 24 may be the same in the vertical direction, or may be expanded as at least the opening at the end is separated from the opening.

  The lower case portion 30 and the upper case portion 23 thus configured are not provided with reinforcing members such as ribs extending in the vertical direction. Since the support member 41 is fixed between the lower case portion 30 and the upper case portion 23 as described above, the upper and lower sides of the case 22 including the lower case portion 30 and the upper case portion 23 are supported by the support member 41. This is because the rigidity in the direction can be reinforced. For this reason, the structure of the lower case part 30 and the upper case part 23 is simplified, and the case 22 can be reduced in size. The lower case portion 30 and the upper case portion 23 are made of a synthetic resin material and are integrally formed. Here, the depth of these case portions is shallower than that of the case 22. For this reason, these case parts can be molded by a mold having a shallow depth, and the mold can be easily manufactured. As a result, the manufacturing cost of the case part can be reduced.

  An intermediate member 80 made of sheet metal is attached to the upper part on the rear side of the upper case portion 23. The intermediate member 80 includes a base 81 that extends in the front-rear direction and is fastened in contact with the upper surface of the upper flange portion 41d of the support member 41; an intermediate portion 82 that extends stepwise from the base 81 to the front side; 82 and a connecting portion 83 extending upward from the front side. The base portion 81 and the connection portion 83 are provided with a plurality of through holes 84 through which fastening means such as bolts are inserted. The connection portion 83 is fastened to another structure portion made of a metal material (not shown) in the front door 10 shown in FIG. For this reason, the heat generated from the stepping motor SM in the reel unit 40 can be radiated to the other structural parts via the support member 41 and the intermediate member 80, and the reel units 40, 40 ′, 40 ″. In addition, it is possible to suppress an increase in the temperature and to suppress electrical noise generated from the stepping motor SM.

Next, a method for assembling the mini main reel device 20 configured as described above will be described with reference to FIG. As shown in FIG. 3, first, the lower case portion 30 is placed so that the opening on the upper side of the accommodating portion 36 of the lower case portion 30 faces upward. Then, the reel unit 40 is moved downward from above the lower case portion 30, and the lower side of the protruding portion 41 b of the support member 41 is inserted into the first guide groove portion 32. At substantially the same time, the lower inclined portion 41 c of the support member 41 is inserted into the engagement groove 31. Here, since the first guide groove portion 32 extends in the vertical direction, an operator (not shown) visually confirms the position of the protrusion portion 41b from directly above the first guide groove portion 32, while the protrusion portion 41b. Can be inserted into the first guide groove 32. For this reason, even if the clearance gap between both when inserting the lower part of the protrusion part 41b into the 1st guide groove part 32 is small, the insertion operation to the 1st guide groove part 32 of the protrusion part 41b can be performed easily.
