<p><P>PROBLEM TO BE SOLVED: To solve the following problems: when a conventional sensor with pressure-sensitive resistance film that detects a resistance value when an indicator is operated in an X-, Y- and Z-axis direction is employed in a projector-type information board having a projection means on the rear side thereof, it has no translucency and information cannot be displayed thereon, and on the other hand, a touch panel cannot detects a resistance value in the Z-axis direction, and it is clear and colorless to cause dazzle on the front side. <P>SOLUTION: The information board 3 that detects a resistance value when the indicator is operated in the X-, Y- and Z-axis directions, and projects light output from the projection means disposed on the side opposite to a viewer includes: a light-transmissive pressure-sensitive resistance sheet 3A having a transmittance of 20-70%; and transparent electrode sheets 3B, 3B each laminated on each of both faces of the pressure-sensitive resistance sheet 3A across dot spacers S. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
