Similarly, even if foreign matter such as a piano wire or wire is intruded from the gap between the open side surface of the front plate 7 or the front lower plate 9 and the front surface of the front frame body 4, The front plate 7 or the front lower plate is caught by catching foreign matter on the locking bracket 72 or the lower locking bracket 83 because it cannot hit the fraud prevention rib 71a and the fraud prevention rib 79a of the front lower plate 9 and cannot enter further. It is possible to reliably prevent an illegal act of opening 9. Further, even if foreign matter such as piano wire or wire enters from the shaft support side of the glass plate holding frame 5, the front plate 7 and the front lower plate 9, the tip of the foreign matter prevents the inner wall member 88 b and the glass plate holding frame 5. It becomes impossible to enter the game area of the game board 15 by hitting against the rib 68b for fraud, the rib 71b for fraud prevention on the front plate 7 and the rib 79b for fraud prevention on the lower front plate 9. It should be noted that fraud prevention plates 89 and 90 are attached to the side edge portions of the front plate 7 and the front lower plate 9 on the pivotal support side to form a double fraud prevention structure.
[0024]
Thus, a fixing member 91 is provided on the open side of the lower front plate 9 and at the lower back position of the metal plate 9a. As shown in FIG. 16, the fixing member 91 is formed of a synthetic resin in a rectangular three-dimensional shape. A cylindrical recess 92 and a mounting boss 93 are integrally formed. As shown in FIG. 15, a metal plate body is formed. A cylindrical recess 92 is fitted into a projection 95 integral with a lower ball receiving tray 8 projecting rearward from a through hole 94 drilled in 9 a, and the projection 95 is inserted into a screw insertion hole 96 drilled in a fixing member 91. The screw 98 is firmly fixed to the front lower plate 9 by fitting and screwing the screw 98 into the screw hole 97. The mounting boss 93 is configured such that the front end of the mounting boss 93 is in contact with the front surface of the front frame 4 with the front lower plate 9 closed, and a mounting hole 99 is provided at the center thereof. In addition, a small through hole 100 for attachment is formed in the main frame portion 11 of the front frame 4 at a position corresponding to the attachment hole 99 of the attachment boss 93.
[0025]
As shown in FIG. 15, the front lower plate 9 having the above-described configuration closes the front lower plate 9 and locks the lower locking fitting 83 to the locking portion 84 of the front frame 4, and then The screw 101 is fitted into the mounting hole 99 of the fixing member 91 from the small through hole 100 and fastened. As a result, the front lower plate 9 is firmly fixed to the front frame body 4 and the lowering of the strength of the front lower plate 9 is suppressed, and surplus spheres from the upper ball tray 6 are placed on the lower ball tray 8. Even if a large amount is stored and a considerable load is applied to the front lower plate 9, the shaft support portion of the front lower plate 9 is not bent or distorted. For this reason, the front lower plate 9 can be smoothly opened and closed even when used for a long period of time, and there is no gap between the front frame body 4 and the front lower plate 9 and fraud is performed. The problem of being easily broken can be solved. Then, it is necessary to open the front lower plate 9 for repair or replacement of the hitting ball launching mechanism 19 attached to the front lower portion of the front frame body 4, the passage member 20, or the speaker 82 provided on the rear surface of the front lower plate 9. In some cases, the fixing member 91 and the front frame 4 can be easily released by releasing the screwing, and then releasing the locking between the flange portion 85 and the locking portion 84 of the lower locking metal fitting 83.
