Abstract
Abstract An information processing apparatus includes a vibration pen for generating a vibration, a transmission propagation member with which the vibration pen is brought into contact so as to propagate the vibration generated by the vibration pen, sensors for detecting the vibration propagating in the vibration propagation member, a CPU for calculating a contact position of the vibration pen from detection times of the vibration detected by the sensors, a mercury switch for detecting an obverse or reverse surface of the vibration propagation member, and a memory for storing coordinate values calculated by the CPU in different memory areas according to a detection result of the mercury switch. Coordinate data may be input selectively from either the obverse or the reverse side of the vibration propagation member, which thereby functions as a reversible input tablet.
