And an inner panel 40 fixed on the back side of the outer panel 31. A design sheet 48 on which a picture is drawn is sandwiched between the outer panel 31 and the inner panel 40. The outer panel 31, the inner panel 40, and the design sheet 48 constituting the lower panel 30 are formed of a transparent material that transmits light from the plurality of LEDs 64 mounted on the printed board 63 mounted in the mounting recess 50. 31 and the inner panel 40 are integrally molded.

  The outer panel 31 and the inner panel 40 of the lower panel 30 are shown in FIG. 4A (surface side exploded perspective view), FIG. 4B (surface side assembly perspective view), FIG. 5A (plan view), FIG. As shown in FIG. 5 (b) (front view) and FIG. 5 (c) (bottom view), the front panel 31 has a rectangular shape, and the outer panel 31 and the inner panel 40 are similar. The outer panel 31 has a plate-like outer panel main body 32 that covers the mounting recess 50, and a protrusion 33 that protrudes obliquely outward is provided on the panel portion side around the outer panel main body 32. The substantially entire back surface of the projecting portion 33 is subjected to graining.

  Graining refers to a process of forming a large number of fine irregularities on the back surface. For example, the protrusion 33 of the outer panel 31 is subjected to a sag processing by, for example, squeezing a part corresponding to a part of the outer panel 31 to be squeezed on the mold surface used when the outer panel 31 is molded. There is a way. The surface processing of the mold is performed by forming a large number of fine irregularities on the surface of the mold by chemical or physical treatment, and then squeezing the processed surface. Such graining can be physically performed by a blasting method such as sand blasting or shot blasting, or can be performed by a chemical method of corroding the surface by an etching method or the like.

  The inner panel 40 has a plate-like inner panel main body 41 that covers the mounting recess 50, and a protrusion 42 that protrudes obliquely outward toward the panel portion is provided around the inner panel main body 41. The substantially entire back surface of the projecting portion 42 is subjected to graining. A first locking portion 43 that protrudes toward the panel portion side and can be locked is provided at a substantially central portion in the left-right direction of the protruding portion 42 on the upper side of the inner panel 40.

  A plurality of plate-like second locking portions 44 that are arranged at a predetermined interval in the left-right direction and extend downward to be locked can be provided at the tip of the protrusion 42 on the lower side of the inner panel 40. . When the inner panel 40 is mounted on the back surface side of the outer panel 31, these second locking portions 44 are arranged so as to substantially coincide with the corresponding second locking portions 34 of the outer panel 31.

As shown in FIGS. 3 and 6 (cross-sectional views), an opening for inserting the second locking portions 34 and 44 is formed on the surface side of the lower portion of the mounting recess 50 to which the lower panel 30 configured in this way is attached. A plurality of portions 51 are provided with a predetermined interval in the left-right direction (mounting recess width direction). The dimensions of these openings 51 in the front-rear direction are set slightly larger than those of the second locking portions 34 and 44. Further, the inner surface 50a on the distal end side of the mounting recess 50 forming the opening 51 extends in the front-rear direction, whereas the protruding portion 33 of the outer panel 31 protrudes obliquely outward toward the panel portion. For this reason, a gap 52 is formed between the outside of the protrusion 33 of the outer panel 31 mounted in the mounting recess 50 and the inner surface 50 a on the tip side of the mounting recess 50, and the clearance 52 attaches the lower panel 30.

The lower panel 30 is attached to the front opening 50b of the mounting recess 50 while being locked to the joint.

  When the light from the LED 64 in the mounting recess 50 strikes the protrusion 42 of the inner panel 40 in a state where the lower panel 30 configured in this manner is mounted in the mounting recess 50, as shown in FIG. In the case where the back surface of each projecting portion 42, 33 of the outer panel 31 is not wrought, this light may pass through each projecting portion 33, 42 and leak to the front side of the slot machine 1. However, since the back surfaces of the protrusions 33 and 42 of the slot machine 1 are subjected to graining, the light from the LED 64 is applied to the protrusions 42 of the inner panel 40 as shown in FIG. 7 (cross-sectional view). When hitting the back surface, this light is diffusely reflected on the back surface of the projecting portion 42 of the inner panel 40 or the back surface of the projecting portion 33 of the outer panel 31 and returned to the mounting recess 50 as indicated by the solid line arrow. For this reason, the amount of light leaking to the front side of the slot machine 1 can be reduced. Accordingly, the amount of light transmitted through the design sheet 48 is insufficient and the picture drawn on the design sheet 48 is not darker than the peripheral portion of the lower panel 30, and the picture drawn on the design sheet 48 is illuminated brightly. It is possible to obtain the same effect as when the peripheral portion of the lower panel 30 is plated. Further, since light does not leak from the periphery of the lower panel 30, the light from the LEDs 64 can be used effectively, and even if the number of LEDs 64 is reduced, the picture drawn on the lower panel 30 can be illuminated sufficiently brightly. it can. For this reason, the cost of the whole gaming machine can be reduced.

However, the protrusion 33 of any one of the outer panel 31 and the inner panel 40 is illustrated. , 42 may be dented. Further, in the above-described embodiment, the entire back inner surface of each of the protrusions 33 and 42 of the outer panel 31 and the inner panel 40 is wrinkled, but the back surface of the protrusions 33 and 42 corresponding to the place where light leaks out. Only a part may be grained. Moreover, although the lower panel 30 was comprised by two members, the outer panel 31 and the inner panel 40, as long as it can manufacture, you may comprise these panels as one. Furthermore, in the above-described embodiment, the slot machine 1 is taken as an example, but a game machine or the like used in a pachinko or game center may be targeted.
