    • 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.

    • A coordinates input apparatus for detecting coordinates of an instructed position from a vibration progagation time on a vibration propagation plate is provided. This apparatus comprises; a vibration pen to generate a vibration; a vibration propagation plate with which the vibration pen is come into contact and which transmits the vibration; a sensor which is arranged in contact relation with the vibration propagation plate and detects the vibration; a vibration-proof material attached to the periphery of the vibration propagation plate so as to have a width of 1/2 of a wavelength of the elastic wave of the vibration; and an operation controller to calculate the contact position of the vibration pen on the vibration propagation plate from the detection time when the vibration was detected by the sensor. The sensor detects the surface wave of the vibration-proof material. With this apparatus, the coordinates of the instructed point can be accurately detected using the vibration with being hardly influenced by the reflected waves from the periphery of the plate.

    • Position information of a first sensor unit and a second sensor unit is calculated using angle information of peaks calculated from a light amount distribution having a plurality of peaks detected by light-receiving unit of the second sensor unit from light emitted by light-emitting unit of the first sensor unit. The coordinates of a pointed position are calculated based on the position information of the first sensor unit and the second sensor unit and a change in a received light amount distribution that occurs due to a pointing to a coordinate input region detected by the light-receiving units. Here, the light-emitting units of the respective multiple sensor units are arranged in known positions relative to the light-receiving units.
