<p>PURPOSE: To provide an input means with variety and to improve information volume to be inputted by changing the resonance state of a resonance circuit in accordance with which, a 1st or 2nd board face, is opposed to a coordinate input face so as to be approximately brought into contact. CONSTITUTION: A casing 110 is provided with 1st and 2nd board faces 111, 112 to be used oppositely to upper and lower sensor faces. In the casing 110, a coil 121 and a capacitor 122 are connected in parallel and a switch 123 and a capacitor 124 are also connected in parallel to constitute a resonance circuit 120. The resonance state of the circuit 120 is changed by turning on/off the switch 123 in accordance with which, the 1st or 2nd board face 111 or 112, is opposed to a coordinate input face so as to be approximately brought into contact. Consequently the input means is provided with variety and information volume to be inputted can be improved.</p> |
