  The sub-control board 17 is housed in a board case 40 for preventing fraud, and the board case 40 is detachably attached to the back side of the effect display device 11g as a unit.

  As shown in FIG. 3 (perspective view), the effect lamps 22 and 22 provided on both lower sides of the panel unit 11 include a plurality of light sources (for example, LEDs) 42 mounted on a printed circuit board 41, and a light source 42. And a lens member 43 attached to the side portion of the panel portion 11.

  The printed circuit board 41 extends in the vertical direction, and the upper end of the printed circuit board 41 extends from the keyhole KY or the adjustment button MR to the inside of the panel unit. The printed circuit board 41 is fixed to the panel unit 11 by fastening means such as bolts. The lens member 43 has an inverted triangular shape when viewed from the front, and its outer end is bent and extends toward the back side of the lens member. A hole 43a for exposing the keyhole KY or the adjustment button MR is formed on the upper portion of the lens member 43. Is provided. A plurality of locking portions 44 each having a protrusion 44 b at the tip of an arm portion 44 a extending toward the rear surface of the lens member 43 are provided on the periphery of the rear surface of the lens member 43. The lens member 43 is integrally formed of a synthetic resin material or the like, and the arm portion 44a can be elastically deformed while being cantilevered. A plurality of mounting holes 45 for locking the protrusions 44 b of the locking portion 44 are provided on both sides of the panel portion 11. In addition, the latching | locking part 44 is good to arrange | position with the space | interval between other neighboring latching | locking parts 44 having a comparatively short distance (for example, 20-30 mm). This is because, when a locking state of one locking portion 44 is released and an illegal act is performed through the mounting hole, the other adjacent locking portions 44 in the locked state are unlocked. Since it is arranged at a relatively short distance with respect to the stop portion 44, even if the rod-shaped member is inserted between the lens member and the panel portion, the deformation amount of the lens member 43 can be reduced, and the rod-shaped member This is because it is difficult to perform the member insertion operation, and fraud can be effectively suppressed.

  When the projection 44b of the locking portion 44 is inserted into the corresponding mounting hole 45 in order to attach the lens member 43 to the side portion of the panel portion 11, the arm portion 44a is elastically deformed so that the projection 44b is within the mounting hole 45. When the projection 44b comes out from the back side of the panel portion of the mounting hole 45, the arm portion 44a tries to return to the original position and the projection 44b is locked to the mounting hole 45, and the peripheral portion of the lens member 43 is the panel. It is mounted on the side of the part 11 with almost no gap. For this reason, it is generally difficult to release the locked state of the protrusion 44b with respect to the mounting hole 45.

  However, the tip of the rod-like member with a thin and sharp tip is inserted between the peripheral edge of the lens member 43 and the side of the panel 11 or holes are formed in the side walls 11a and 11b of the panel 11 outside the arm 44a. Opening and inserting a rod-like member through this hole makes it possible to press the arm portion 44a from the lateral direction and to release the locking state of the projection 44b with respect to the mounting hole 45. As a result, the attachment hole 45 is opened, and there is a possibility that an unauthorized operation is performed on the power supply device board 34 provided in the main power supply device PWU shown in FIG.

  Therefore, as shown in FIG. 4 (back side perspective view), a rib 47 is provided on the back surface of the panel portion 11 so as to surround the attachment hole 45 and project toward the back surface side of the panel portion. The rib 47 has a substantially rectangular shape in a rear view, and a first rib 47a extending along the side walls 11a and 11b of the panel portion 11 and a second rib extending in the width direction of the panel portion connected to the upper end portion of the first rib 47a. The rib 47b includes a third rib 47c that is connected to the lower end of the first rib 47a and extends in the width direction of the panel portion, and the tip ends of the second rib 47b and the third rib 47c are sidewalls of the panel portion 11. 11a and 11b. These ribs 47a, 47b, 47c have substantially the same height.

  When the vertical frames 14 and 15 of the frame 13 are attached to the side portions of the panel portion 11, the lower portions of the vertical frames 14 and 15 cover the openings that open to the upper portions of the ribs 47 arranged in a rectangular shape. As a result, the space on the back side of the panel portion of the mounting hole 45 is closed.

  For this reason, even if a rod-shaped member (not shown) is inserted from the panel portion surface side of the mounting hole 45 and an unauthorized operation is attempted on the power supply device board 34 of the main power supply device PWU shown in FIG. Can not extend outward from the space surrounded by the ribs 47, the side walls 11a and 11b, and the vertical frames 14 and 15, so that illegal acts on the power supply board 34 can be surely prevented. It is possible to surely prevent a situation in which a lottery probability is changed to a high value and the number of medals to be paid out increases to prevent a fair game from being provided.

In addition , the shape of the rib 47 in the rear view may be any of a triangular shape, a circular shape, an arc shape, and the like in addition to the rectangular shape. Further, in the present embodiment, the case where the rib 47 is provided on the back side of the panel portion of the mounting hole 45 for locking one locking portion 44 of the lens member 43 is shown. Similar ribs may be provided on the whole or a part of the panel portion back side.
