摘要:
In a coordinates input apparatus in which a vibration input from a vibration pen is detected by a plurality of vibration sensors attached to a transparent vibration propagating plate such as an acrylic or glass plate and the coordinate position of the vibration pen is detected from the vibration propagation times until the vibration sensors, the sensors and the vibration proof material are arranged in a manner such that a distance between the attaching boundary surface of the vibration proof material attached to the peripheral portion of the vibration propagating plate and the center of each sensor which is attached to the input side than the attaching boundary surface of the vibration proof material lies within a range from 0.5 time to a value less than 1.0 time as large as the diameter of the sensor, preferably, within a range from 1.0 mm to a value less than 2.0 mm.
