    摘要: Disclosed is a coordinate input apparatus for detecting an input vibration from a vibration pen by a vibration sensor provided on a vibration transmitting plate to measure a vibration transmission time to the vibration pen to detect the input coordinates of the vibration pen on the vibration transmitting plate on the basis of the measurement result. The vibration pen is made wireless by incorporating all mechanisms required to generate the vibration. A drive timing for vibration input from the vibration pen and used as a measurement origin of the vibration transmission time is transmitted to a main body for performing the coordinate detection processing by bringing the vibration pen in temporary contact with the main body.

    摘要: A coordinate input apparatus includes a vibration pen, a vibration transmission plate, a plurality of vibration detecting units, a calculating unit, a memory unit, and a control unit. The calculating unit calculates vibration transmission times from a point designated by the vibration pen to the vibration detecting units, and calculates coordinate values of the designated point of the vibration pen. The memory unit stores the vibration transmission times from a first designated point of the vibration pen on the vibration transmission plate to the vibration detecting units and coordinate values of the first designated point. The control unit performs calculations on the basis of vibration transmission times from a second designated point calculated by the calculating unit to the vibration detecting units, the vibration transmission times from the first designated point and the coordinate values of the first designated point stored in the memory unit, thereby calculating coordinate values of the second designated point.

    摘要: A coordinates input apparatus, for example, a digitizer, has a vibration propagation medium such as a transparent glass plate for allowing a vibration to propagate therethrough; an input pen for applying vibration to the vibration propagation medium; a vibration detector for detecting vibration applied by the input pen; an envelope output device for producing an envelope signal representing the envelope of the vibration detected by the vibration detector; a differentiator for conducting a differentiation of the envelope signal produced by the envelope output device so as to determine the peak; a controller adapted for determining, as the time of arrival of the vibration, a zero-cross point of the vibration that is located in the vicinity of a zero-cross point of the signal from the differentiator; and a computing device for computing the distance between the input pen and the vibration detector from the time determined by the controller.
