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.

摘要： Position coordinates in a space defined by the first to third axes of a coordinate input pointing tool are calculated. A coordinate output form includes at least an absolute coordinate output form in which calculated coordinate values are directly output, and a relative coordinate output form in which the differential values between the calculated coordinate values and predetermined coordinate values are output. The value of the first axis of the calculated coordinate values is compared with a predetermined value. It is determined whether the coordinate values of the second and third axes of the calculated coordinate values fall within a predetermined range. The calculated coordinate values are output in a coordinate output form determined on the basis of the comparison result and determination result.

摘要： A coordinate input apparatus includes retroreflecting units at two opposite sides of a rectangular-shaped coordinate input effective region, and a plurality of sensor units provided at the two sides. Each of the sensor units includes a light receiving unit for receiving light that reaches the light receiving unit, a light projecting unit for projecting light toward a retroreflecting unit provided at one of the two sides, which opposes the light projecting unit, and a surface light emitting unit for emitting even diffused light from a band-shaped surface. Each of the sensor units simultaneously detects, by the light receiving unit, light that has been projected by the light projecting unit and reflected back by the retroreflecting unit at the side opposing the light projecting unit, and light that has been emitted by surface light emitting units of a plurality of sensor units at the side opposing the light projecting unit.
