Abstract:
An information processing apparatus comprising:a) coordinate information input means comprising a pen and a tablet for inputting coordinate data, said pen and tablet being coupled by electrical coupling means;b) processing means for processing said coordinate data;c) detecting means for detecting a velocity of changing said input coordinate data sequentially, said detecting means detecting said velocity of changing during a period of pressing said pen to said tablet, and for detecting whether or not said pen is pressed to said tablet;d) switching means for switching an operating mode of said apparatus according to said velocity of changing;e) said processing means having at least two operating modes, a first of said modes is selected by detecting that said velocity is at a level which is lower than a predetermined level and the pen is pressed to the tablet, and a second mode is selected by detecting that said velocity is at a level which is higher than said predetermined level and said pen is not pressed to the tablet, and means for changing the image information displayed on said display in accordance with each said mode;f) said velocity is detected at least in two conditions, one of said conditions is that said pen is down on said tablet so as to give a pressure to said tablet, and other said condition is that said pen is up from said tablet within a distance which can be detected by said tablet as a pen up condition.
