<p><P>PROBLEM TO BE SOLVED: To prevent dimming of the display in a symbol display caused by the influence of dust. <P>SOLUTION: In the pachinko game machine, an arm 164 is moved in the vertical direction when a lift motor 156 is driven, and dust is wiped from the rear face of a game board by a front brush 166 and wiped from the display screen of the symbol display by a rear brush 168. When the lift motor 156 is operated, a blower 172 is operated, and the dust is sucked into the arm 164 from a front suction nozzle 165 and a rear suction nozzle 167 and transferred from inside the arm 164 into a dust box 177 through a suction hose 170. Accordingly, the dust can be wiped and discharged from the rear face of the game board and from the display screen of the symbol display without detaching the game board from the symbol display even if the game board and the symbol display are jointed to each other, and therefore, dimming of the display in the symbol display can be prevented. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
