The side is the right side of the liquid crystal substrate box 33.

  As shown in FIG. 3, plate-like fixing pieces 41 extend laterally from the right side surface and the left side surface of the rectangular parallelepiped liquid crystal substrate box 33. In the vicinity of the upper and lower ends of each fixing piece 41, a fixing hole 42 through which a screw 38 (see FIG. 2) is inserted is formed. The liquid crystal substrate box 33 can be fixed to the game board 2 by inserting the screw 38 through the fixing hole 42 and fastening it to a screw hole (not shown) formed in the game board 2.

  The right side of the back surface 43 (the front surface in FIG. 3) of the liquid crystal substrate box 33 is an installation position 40 where the sub substrate box 35 is disposed. A first holding rib 45 is erected at the lower end of the installation position 40. The first holding rib 45 extends straight from the right end portion of the back surface 43 to the left and is bent vertically upward at the lower left end portion of the installation position 40. The operator can easily align the sub-board box 35 with respect to the installation position 40 only by bringing the left lower end portion of the sub-board box 35 having a rectangular parallelepiped shape into contact with the bent portion 46 of the first holding rib 45. Can do. Further, a second holding rib 47 is erected in the vertical center of the left end portion of the installation position 40. The first holding rib 45 and the second holding rib 47 are erected along the end of the installation position 40. That is, the first holding rib 45 and the second holding rib 47 correspond to the outer peripheral shape of the sub-board box 35.

  In the back surface 43, cylindrical convex portions 50 protrude in the vicinity of the four corners of the installation position 40. The convex portion 50 is integrally formed with the liquid crystal substrate box 33 by a synthetic resin.

  As shown in FIG. 4, the outer peripheral edge of the tip portion of the convex portion 50 is chamfered. That is, a chamfered portion 51 whose diameter decreases toward the distal end side is formed on the outer peripheral edge of the distal end portion of the convex portion 50. Thereby, fitting of the convex part 50 to the concave part 60 mentioned later can be performed easily.

  Next, the structure of the sub-board box 35 will be described with reference to FIGS. As shown in FIG. 5, a fixing piece 55 is provided slightly to the right of the center of the upper end portion of the sub board box 35. A fixing hole 56 through which the screw 39 (see FIG. 2) is inserted is formed in the fixing piece 55. The upper end portion of the sub board box 35 can be fixed to the game board 2 by inserting the screw 39 into the fixing hole 56 and fastening it to a screw hole (not shown) formed in the game board 2. In addition, a sealing portion 57 that seals the box is provided on the upper right end portion of the sub-board box 35 in order to prevent unauthorized access to the sub-integrated board stored therein. A screw (not shown) that can rotate only in the tightening direction is fastened to the sealing portion 57.

  Further, as shown in FIG. 5, four concave portions 60 are provided on the front surface 58 of the sub substrate box 35 at positions corresponding to the convex portions 50 of the liquid crystal substrate box 33. The recess 60 is made of a synthetic resin having moderate elasticity.

  In the following description, the lower left side in FIG. 6 is the front side of the recess 60, and the upper right side in FIG. 6 is the back side of the recess 60. As shown in FIG. 6, the recess 60 has a square shape when viewed from the front and a rectangular parallelepiped shape, and includes a base 61, an upper wall 62, a left wall 63, a right wall 64, and a lower wall 65. I have. The base 61 is a square plate-like member having a predetermined thickness. The upper wall portion 62 is erected in the vertical direction from the upper end portion of the base portion 61 to the front side. Similarly, the left wall 63 is erected from the left end of the base 61, the right wall 64 is erected from the right end of the base 61, and the lower wall 65 is erected from the lower end of the base 61 in the same direction as the upper wall 62. ing. The thicknesses of the upper wall portion 62, the left wall portion 63, the right wall portion 64, and the lower wall portion 65 (hereinafter collectively referred to as “wall portions 62 to 65”) are all constant and the width in the front-rear direction. Are all constant. The convex portion 50 is inserted into the concave space surrounded by the wall portions 62 to 65.

  A first positioning rib 71 projects upward at the center of the inside of the lower wall portion 65. The first positioning rib 71 extends from the distal end portion of the lower wall portion 65 to the base portion 61 at a constant height. Two second positioning ribs 72 protrude upward on the left and right sides of the first positioning rib 71. The distance between the first positioning rib 71 and the left and right second positioning ribs 72 is the same. The second positioning rib 72 extends to the base 61 at a certain height from the rear end side slightly from the front end portion of the lower wall portion 65. The height of the two second positioning ribs 72 is formed to be higher than the height of the first positioning rib 71 in correspondence with the shape of the columnar convex portion 50. Therefore, the 1st positioning rib 71 and the 2nd positioning rib 72 can position the convex part 50 appropriately. The first positioning rib 71 and the second positioning rib 72 are not only fixed to the lower wall portion 65 but also the rear end portion is fixed to the base portion 61. Thereby, it is possible to prevent the first positioning rib 71 and the second positioning rib 72 from being bent, and to reliably position the convex portion 50.

  In addition, a first positioning rib 71 and two second positioning ribs 72 are provided on the inner side of the upper wall portion 62 similarly to the lower wall portion 65. The first positioning rib 71 and the second positioning rib 72 of the upper wall portion 62 are provided at positions symmetrical to the first positioning rib 71 and the second positioning rib 72 of the lower wall portion 65 around the center line P. Yes. The center line P is a line that passes through the center point of the base 61 and is perpendicular to the wall surface of the base 61. That is, when the columnar convex portion 50 is fitted into the concave portion 60, the convex portion 50 comes into contact with the positioning ribs 71 and 72 at a plurality of positions symmetrical about the central axis of the concave portion 60 and is positioned at an appropriate position. The The central axis of the positioned convex portion 50 coincides with the center line P.

  Inside the left wall 63, two fixing ribs 73 are erected on the right. The distance between the upper fixing rib 73 and the upper wall portion 62 is the same as the distance between the lower fixing rib 73 and the lower wall portion 65. The fixing rib 73 extends from the distal end portion of the left wall portion 63 to the base portion 61, but the height of the distal end portion of the fixing rib 73 is lower than the height of other portions. Further, the fixing rib 73 is only fixed to the left wall portion 63, and the rear end portion of the fixing rib 73 is not fixed to the base portion 61. Therefore, the fixing rib 73 can be appropriately bent, and the convex portion 50 can be firmly fixed by the repulsive force.

  In addition, two fixing ribs 73 are provided on the left side of the right wall portion 64 in the same manner as the left wall portion 63. The two fixing ribs 73 of the right wall portion 64 are provided at positions that are symmetrical with the two fixing ribs 73 of the left wall portion 63 with the central axis P as the center. Therefore, the total four fixing ribs 73 can apply a force evenly to the convex portion 50, and the convex portion 50 is fixed in a stable state.

  As shown in FIG. 7, the recess 60 is provided so as to enter the back side (upper side of the drawing in FIG. 7) than the front side 58 of the sub-board box 35. Thereby, the position of the end face on the front side of the recess 60 is matched with the position of the end face on the front side of the sub-board box 35. Accordingly, the contact area between the sub substrate box 35 and the liquid crystal substrate box 33 is increased as compared with the case where both end surfaces do not match, and the sub substrate box 35 is temporarily fixed in a stable state.

  Next, the procedure and effects for temporarily fixing the sub substrate box 35 to the liquid crystal substrate box 33 will be described. First, as shown in FIG. 8, the worker brings the left lower end portion of the sub-board box 35 having a rectangular parallelepiped shape into contact with the bent portion 46 of the first holding rib 45. Then, the position of the sub substrate box 35 with respect to the liquid crystal substrate box 33 is accurately defined by the first holding rib 45 and the second holding rib 47. Therefore, the operator can easily align the sub-board box 35 with respect to the installation position 40 (see FIG. 3) in the vertical and horizontal directions.

  Next, the operator pushes the sub-board box 35 in the aligned state to the front side (the lower side of the drawing in FIG. 8). Then, each of the four convex portions 50 (see FIG. 3) provided on the back surface 43 of the liquid crystal substrate box 33 fits into the concave portions 60 (see FIG. 5) provided in the sub substrate box 35, and the sub substrate box. 35 is temporarily fixed at the installation position 40 (see FIG. 3) of the liquid crystal substrate box 33. Therefore, the sub-board box 35 can be temporarily fixed easily and firmly by simply pushing the sub-board box 35 from one direction without going through a complicated procedure for engaging the members.

  For example, the sub-board box 35 is removed from the main body of the pachinko machine 1, the ROM stored in the sub-board box 35 is replaced, and the operation check of the pachinko machine 1 is frequently performed in the development stage. Also, when the pachinko machine 1 is repaired, the sub-board box 35 is fixed to and removed from the main body of the pachinko machine 1. Thus, when fixing the sub board | substrate box 35 to the main body of the pachinko machine 1, conventionally, it was necessary to perform a fixing operation | work using a screw | thread every time, and work efficiency was bad. There was also a problem that the screws were scattered in the workplace and were troublesome. However, according to the pachinko machine 1 of the present embodiment, the operator can easily and firmly temporarily fix the sub-board box 35, and can confirm the operation in the temporarily fixed state. Therefore, work efficiency is dramatically improved. Even when the pachinko machine 1 is assembled, it is only necessary to temporarily fix the sub board box 35 and then fix it with screws. Therefore, it is not necessary to perform fixing work with screws while holding the sub board box 35 at the installation position 40. The sub-board box 35 is temporarily fixed and the operation is confirmed. After confirming that the sub-board box 35 is operating normally, the fixing work can be performed with screws. can do.

  Further, as described above, the chamfered portion 51 is formed on the outer peripheral edge of the tip portion of the convex portion 50 (see FIG. 4). Therefore, even when the position of the convex portion 50 and the position of the concave portion 60 are slightly shifted, the chamfered portion 51 is guided by the first positioning rib 71 and the second positioning rib 72 (see FIG. 6), and the convex portion 50 is Fits smoothly into the recess 60. Further, since the convex portion 50 is formed in a columnar shape instead of a prismatic shape, it is not necessary to consider the phase matching between the convex portion 50 and the concave portion 60.

  As shown in FIG. 6, the first positioning rib 71 extends from the top end portions of the upper wall portion 62 and the lower wall portion 65 to the base portion 61, and the second positioning rib 72 includes the upper wall portion 62 and the lower wall portion. It extends from the rear end side to the base 61 slightly from the front end portion of 65. Therefore, in the process in which the convex portion 50 is pushed in, first, the convex portion 50 enters the concave portion 60 while being vertically positioned by the two first positioning ribs 71. Thereafter, positioning in the left-right direction is also performed by the four second positioning ribs 72, and the temporary fixing of the sub-board box 35 is completed. That is, the convex portion 50 is gradually guided to an appropriate position while being pushed. Therefore, it is not necessary to perform the temporary fixing operation after the alignment of the convex portion 50 and the concave portion 60 is performed. Further, the tip side portion of the fixing rib 73 having a slightly low height also serves to define the position of the convex portion 50 at the stage where the pressing of the convex portion 50 is started. Therefore, positioning of the convex part 50 is performed more smoothly.

  As shown in FIG. 9, according to the temporary fixing structure of the control board box of the present embodiment, the sub board box 35 is held by the fitting of the convex portion 50 and the concave portion 60, and in addition, the first holding rib 45. The outer periphery is held by. Similarly, the second holding rib 47 (see FIG. 3) holds the outer periphery of the sub board box 35. Therefore, the sub substrate box 35 is temporarily fixed to the liquid crystal substrate box 33 more firmly.

  As shown in FIG. 10, when the convex portion 50 is pushed into the concave portion 60, the four fixing ribs 73 having elasticity are in contact with the peripheral wall surface of the convex portion 50 obliquely and bent. Specifically, the tip of the upper fixing rib 73 is bent upward, and the tip of the lower fixing rib 73 is bent downward (the arrow direction in FIG. 10 indicates the bending direction). The bent fixing rib 73 presses the convex portion 50 by a repulsive force. Therefore, the sub substrate box 35 can be temporarily fixed to the liquid crystal substrate box 33 easily and firmly. Since the four fixing ribs 73 are provided at positions that are symmetric with respect to the central axis of the convex portion 50, force is equally applied from the four fixing ribs 73 to the convex portion 50. Therefore, the sub board box 35 can be temporarily fixed in a stable state.

  The concave portion 60 includes a first positioning rib 71 and a second positioning rib 72 that contact the peripheral wall surface of the cylindrical convex portion 50 to position the convex portion 50. Thereby, the sub board | substrate box 35 can be positioned in an exact position. The plurality of first positioning ribs 71 and the second positioning ribs 72 are arranged at positions that are symmetrical about the central axis of the convex portion 50 that fits into the concave portion 60. Therefore, the force applied to the plurality of first positioning ribs 71 and the second positioning ribs 72 can be evenly distributed, and the sub-board box 35 can be temporarily fixed in a more stable state. Furthermore, since a large load is not applied to the specific rib, the risk of the rib being worn or damaged can be reduced.

  It should be noted that the present invention is not limited to the embodiment described in detail above, and various modifications can be made without departing from the scope of the present invention. For example, in the above-described embodiment, the concave portion 60 is provided in the sub substrate box 35 and the convex portion 50 is provided in the liquid crystal substrate box 33. However, it goes without saying that the recess 60 may be provided in the liquid crystal substrate box 33 and the protrusion 50 may be provided in the sub-substrate box 35.

  In the above embodiment, the structure for temporarily fixing the sub substrate box 35 to the installation position 40 of the liquid crystal substrate box 33 has been described. However, it goes without saying that the present invention can be applied to other than temporary fixing of the sub-board box 35. For example, the present invention may be applied to temporarily fix the effect control board box 34 to the liquid crystal board box 33. The present invention may be applied to temporarily fix the liquid crystal substrate box 33 to the game board 2.

  In the said embodiment, although the convex part 50 is formed in the column shape, you may form in a prismatic shape. Further, the outer shape of the concave portion 60 does not need to be a rectangular parallelepiped shape, and the concave portion 60 can be changed to another shape such as a bottomed cylindrical shape.

  In the above embodiment, the convex portion 50 is fixed by bending and deforming the fixing rib 73 to generate a repulsive force. However, a repulsive force may be generated by deforming the tip of the fixing rib 73 having elasticity. Also in this case, the convex part 50 can be firmly fixed similarly to the said embodiment. The number of the fixing ribs 73, the arrangement position, and the like can be changed as appropriate. For example, like the first positioning rib 71 and the second positioning rib 72, a plurality of fixing ribs having different heights may be provided.

  The number and arrangement positions of the first positioning ribs 71 and the second positioning ribs 72 can also be changed. For example, when the convex portion 50 is formed in a quadrangular prism shape instead of a cylindrical shape, it is not necessary to make the height of the first positioning rib 71 different from the height of the second positioning rib 72.

  In the above embodiment, the first holding rib 45 and the second holding rib 47 that hold the lower end portion and the left end portion of the sub-board box 35 from the outside are provided. However, the holding ribs may be formed so as to hold all four ends of the upper, lower, left and right sides. You may form a holding rib so that the perimeter of an outer periphery may be hold | maintained. The present invention can be applied not only to pachinko machines but also to various game machines such as pachislot machines.
