<p><P>PROBLEM TO BE SOLVED: To dispense with glass cleaning work of a parlor employee by automatically retaining the front face side of the glass in a clean state even if a player's finger frequently touches the front face of the glass. <P>SOLUTION: When the number of times that the player touches the glass 14 in front of a touch sensor 48 with a finger reaches 50, a part of a transparent film 18 covering the glass 14 in front of the touch sensor 48 moves and, as a substitute for it, a part of a clean transparent film 18 covers the glass 14 in front of the touch sensor 48 to be replaced. This constitution can utterly dispense with the glass cleaning work by the parlor employee. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
