<p>PROBLEM TO BE SOLVED: To provide a tablet without the need of a cable in a position indicator and to improve operability by operating an operation knob provided with a magnet and moving a conductive moving body from the outer side of a conductive pattern surface by magnetic attraction force. SOLUTION: When the operation knob 160 is provided with the magnet (permanent magnet) 161 and the operation knob 160 is moved on a surface sheet 113, by attraction force between the magnet 161 and the magnet 150 arranged in a clearance 140 formed by a spacer 130, the magnet 150 is moved along a coordinate read surface in the clearance 140. For the surface sheet 113, it is preferable to select a material for not generating the noise of excessive static electricity between the surface sheet 113 and the operation knob 160 when an operator moves the operation knob 160 on the surface sheet 113. Thus, the cordless operation knob 160 is realized, the operability is improved and the operation knob 160 is prevented from being moved at the time of not being operated by the magnetic attraction force.</p> |
