  FIG. 1 is a front view of a winning ball receiver that is a board surface component of a gaming machine and has a printed wiring board according to the present invention. 2 is a sectional view of the winning ball receiver along the line II-II in FIG. 1, and FIG. 3 is a sectional view of the front wall of the cover portion along the line III-III in FIG. . The housing 2 of the winning ball receiver 1 is composed of a container portion 21 in which an operation member 3 (FIG. 2) is stored, and a cover portion 22 attached to the front surface thereof. An opening 212 is formed in the front wall 211 of the container portion 21, and the outer peripheral portion of the front wall 211 is a mounting flange. The cover portion 22 has a substantially L-shaped cross section including a bottom wall 221 that contacts the front wall 211 of the container portion 21 and a front wall 222 that curves and rises from the bottom wall 221 (FIG. 2). The front wall 222 is formed in a predetermined shape having a narrower width than the front wall 211 (FIG. 1), and extends substantially parallel to the front wall 211 at a constant interval. A pair of shaft bodies 223 projecting toward the front wall 211 are formed on the rear surface of the front wall 222 at the middle left and right positions in the vertical direction. The shaft bodies 223 are respectively provided with bases of wing-like movable pieces 4A and 4B. The end is fitted with a through-hole so as to be rotatable.

  Each of the movable pieces 4A and 4B positioned between the front and rear front walls 211 and 222 is formed into a curved shape in which the opposed inner surface is formed into a flat shape and the outer surface is swelled. In a state where the movable pieces 4A and 4B are in the closed posture, the left and right movable pieces 4A and 4B are in the standing posture with the inner side surfaces facing each other substantially in parallel (FIG. 1). In a state where the movable pieces 4A and 4B are in the open posture, the left and right movable pieces 4A and 4B are tilted away from each other, and the opening diameter of the winning opening 11 formed between the movable pieces 4A and 4B is increased. The operation member 3 disposed in the container part 21 is a rectangular plate body, and a shaft member 31 penetrating in the width direction at an intermediate position thereof is rotatably supported between the side walls of the container part 21, and a balance. Can be tilted to the formula. In the tilted state, the operation member 3 has its front end portion 34 lowered, and the entire operation member 3 is slightly inclined downward. In the inclined state in which the front end portion 34 is raised as shown by the chain line in FIG. 2, the entire operation member 3 is greatly lowered and inclined backward.

  The front end portion 34 of the operation member 3 in the tilted state is positioned so as to interrupt between the base end portions of the left and right movable pieces 4A and 4B, and the movable pieces 4A and 4B are raised and closed (FIG. 1). When the game ball enters the winning opening 11 in this state, the game ball rolls backward on the operation member 3 from the front end portion 34 of the operation member 3, and the rear end portion 35 of the operation member 3 is lowered by the load. The operation member 3 is inclined. As a result, the front end portion 34 of the operating member is detached upward from between the base end portions of the left and right movable pieces 4A and 4B, and the movable pieces 4A and 4B are tilted and opened. When the game ball enters the winning opening 11 with the movable pieces 4A and 4B opened, the game ball contacts the contact portion 40 protruding from the front end portion 34 of the operation member 3, and the load of the operation member 3 is increased. The front end portion 34 is lowered and the movable pieces 4A and 4B are returned to the closed posture again.

  The front surface of the cover portion front wall 222 is a display portion D. In the display portion D, most of the front surface of the front wall except the outer peripheral edge is shallowly recessed to form a display surface 224. The display surface 224 is gently curved so as to be convex forward (FIG. 3), and the printed wiring board 5 described in detail below is disposed on the display surface 224. FIG. 4 shows a plan view of the printed wiring board 5, and FIG. 5 shows a cross-sectional view taken along the line V-V in FIG. The printed wiring board 5 includes a substrate body 51 made of a transparent and flexible resin film. The substrate body 51 includes a general portion 52, a cutout portion 53, a punched hole portion 54, and a narrow width portion 55. It is configured. The general portion 52 is a wide portion having a substantially similar shape that is slightly smaller than the display surface 224 of the front wall 222 of the cover portion. A light emitting diode chip 6 as a body chip is provided. Each of these light emitting diode chips 6 is connected to one end of a wiring (not shown) formed on the substrate body 51 by die bonding. Each wiring extends from the general portion 52 through the notch portion 53 adjacent thereto, extends from the punched hole portion 54 to the narrow width portion 55, and is input-connected to a connector 56 provided at one end of the narrow width portion 55. .

  In the notch 53, notches 531 are formed on both side edges of the substrate body 51 so as to enter the plate surface inward at a fixed length. Further, in the hole 54 that follows the notch 53, a hole 541 is formed in a plate surface portion where no wiring is formed. In the narrow width portion 56 following the punched hole portion 54, the interval between adjacent wirings extending to the connector 56 is relatively small, and the plate width is narrowed to about 1/4 of the general portion 52.

  In such a printed wiring board 5, the general part 52 of the board body 51 is positioned on the display surface 224 of the front wall 222 of the cover part with the front side thereof positioned forward. Then, the cutout portion 53 and the punched hole portion 54 are positioned at the position where the substrate body 51 starts to bend along the lower end curved portion of the front wall 222. The narrow width portion 55 of the substrate body 51 enters the cover portion 22 through the opening 225 provided at the lower end of the front wall 222 while being largely curved, and the connector 56 provided at one end thereof is connected to the bottom wall of the cover portion 22. 221 is located. In this state, the light emitting diode chips 6 provided on the back surface side of the general portion 52 of the substrate body 51 are respectively positioned in the openings 226 provided on the front wall 222 corresponding to these.

It is fixed on the display surface 224 by the attached seal body 7. An appropriate design pattern is attached to the surface of the seal body 7, and a predetermined region of the seal body 7 corresponding to the light-emitting diode chip 6 provided in the general portion 52 of the substrate body 51 diffuses the body of the seal body 7. The light emitted from the back side of the light-emitting diode chip 6 to the front of the front wall 222 is scattered by, for example, a material having a function.

  As described above, in this embodiment, the notch 531 of the notch 53 is formed on both side edges of the printed circuit board 5 where the board body 51 starts to be bent, so that stress generated on both side edges is reduced. Is done. Subsequently, since a plurality of punch holes 541 of the punch hole portion 54 are formed in the plate surface at a portion where the substrate body 51 is curved, the substrate body 51 is easily bent, and stress generated on the plate surface is reduced. Further, a narrow width portion 55 is located at a portion where the substrate body 51 is largely curved into the opening 225, and the board width of the substrate body 51 is significantly narrowed. Stress generated on the surface is reduced. In this way, the load applied to the substrate body 51 along with the curvature is reduced, and the durability is improved. Note that it is not necessary to provide all of the cutout portion 53, the punched hole portion 54, and the narrow width portion 55 provided in the curved portion of the substrate body 51. If one or more of them are provided, the effect of improving the durability is achieved. Is obtained.
