    摘要： A device has a projection type image display unit which has a projection lens and generates a coordinate input screen, and linear sensors for sensing an image of a beam spot, and computes a coordinate value corresponding to the beam spot on the basis of information obtained by the projection type image display unit and the output signals from the linear sensors. This beam spot is generated by irradiating the predetermined position on the coordinate input screen with light coming from a pointing tool, or corresponds to a light-emitting portion provided to the distal end of the pointing tool located near the coordinate input screen.

    摘要： The invention aims to provide a coordinate input apparatus having high detection reliability and high efficiency and to control the influence of ambient light using a simple structure. The apparatus detects a light spot flashing on and off in a predetermined cycle and incident at a desired position on a coordinate input screen, and includes a detection device having photoelectric conversion elements corresponding to N pixels for detecting a light spot coordinate. The difference between signals from photoelectric elements in light emission state and in light non-emission state at each N pixel is found, and the smaller of the difference signals of the m-th pixel having the maximum difference signal is set as a threshold value. Effective pixels are identified based on the threshold value, and the coordinate is calculated by using the difference data of the selected effective pixels.

    摘要： A cap covering a light-emitting element attached to the distal end of an indicator is held by a sliding member, and is slidably attached axially along the indicator. By pressing/separating the cap against/from a coordinate input surface, a tact switch operates interlockingly with the cap to switch driving control of the light-emitting element. For example, the light-emitting element is driven by pressing the cap, and driving of the light-emitting element is stopped by separating the cap. Since the cap covers the light-emitting element, the light-emitting element can be prevented from being worn and scratched. Driving control of the light-emitting element need not be additionally switched, resulting in high operability.
