<p>PURPOSE:To prevent a position detector from the generation of malfunction by canceling a signal due to hand touch, out of detecting signals of a vibration unit. CONSTITUTION:An I/O panel 1 is constituted of a touch panel 40 consisting of a vibration detecting unit 30 and a conductive plate arranged on a tablet 10 through a shielding plate 20. When the touch panel 40 is depressed by a magnetic generator 3, the interval between the 1st and 2nd plate materials 31, 32 constituting the unit 30 is changed, stress due to a projection part is applied to a vibration sensor and a signal is outputted. Since the plate materials 31, 32 are similarly vibrated by external vibration, the change of the interval is not generated and no signal is extracted. On the other hand, hand touch is detected from the touch panel 40 and a signal extracted from the vibration generated in the unit 30 at the time of hand touch is canceled.</p> |
