<p><P>PROBLEM TO BE SOLVED: To increase a performance effect by substantially changing a visible area including the entire change so as to demonstrate the maximum effect of using a large-sized display device. <P>SOLUTION: When a shielding plate 58 is positioned on one end side of the rotation range of a motor 70 (first position), the display area of an LCD 54 is visible from the entire range of a special through-hole 56C. When the shielding plate 58 is positioned on the other end side of the rotation range of the motor 70 (second position), the entire special through-hole 56C is shielded and the display area of the LCD 54 is invisible. On the other hand, when the shielding plate 58 is at the first position, the display area of the LCD 54 is visible from the entire range of a normal through-hole 56B. When the shielding plate 58 is at the second position, the entire normal through-hole 56B is shielded and the display area of the LCD 54 is invisible. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
