ABSTRACT:
It is an object to provide a portable coordinates input apparatus which can be manufactured at low costs. An input pen applies a voltage to a desired position in a coordinate input area on a vibration propagating plate having a piezoelectric performance and having a first surface including the coordinate input area and a second area that faces the first surface. A vibration generated by the voltage is detected as an electric signal by a vibration detecting electrode arranged out of the coordinate input area.
