Abstract:
A touch panel device for displaying information containing predetermined attributes comprising:a flat display device; a touch panel in front of the flat display device; an input pen for touching the touch panel, the input pen comprising: a signal oscillating section for oscillating a signal; a setting section for setting a frequency or an output level of the oscillated signal from the signal oscillating section; and a set value changing section for changing a set value of the frequency or the output level in the setting section; a sensing section for sensing the frequency or the output level of the oscillated signal from the signal oscillating section in the input pen at a touch position on the touch panel by the input pen; an attribute setting section for setting the attributes of input information in response to the frequency or the output level of the oscillated signal sensed by the sensing section; and a displaying section for displaying the input information on the flat display device based on the attributes set by the attribute setting section, wherein the input pen has an opening portion formed at a top end portion, and the oscillated signal that is output by the signal oscillating section being built in the input pen is oscillated from the opening portion to have a directivity of 360 degree around a penholder of the input pen.
