Abstract:
An electronic pen device comprising:first measuring means for measuring movement loci of a pen point in directions X and Y on the basis of a detection result in a ball rotation sensor detecting rotation of a ball provided on said pen point; contact state determination means for determining whether said pen point is in a contact state or in a noncontact state with an entry plane; second measuring means for measuring movement loci of said pen point in said directions X and Y on the basis of acceleration detected by an acceleration sensor; movement locus operation means for obtaining a contact movement locus of said pen point on the basis of a measurement result in said first measuring means when said contact state determination means determines that said pen point is in said contact state with said entry plane while obtaining a noncontact movement locus of said pen point on the basis of a measurement result in said second measuring means when said contact state determination means determines that said pen point is in said noncontact state with said entry plane; correction means for correcting said measurement result from said second measuring means when said pen point is in said noncontact state based on a measurement result received from said first measuring means determined when the pen point is in a prior contact state; a telephone circuit for making communication with the destination of transmission/receiving, a microphone for inputting a transmission a speaker for outputting a receiving tone, and call control means obtaining a telephone number of the destination of transmission on the basis of a character string recognized, by said character recognition, and means arid outputting said obtained telephones number to said telephone circuit for allowing said telephone circuit to make a call.
