Title:
表示機能を内蔵した画像入力装置
Document Type and Number:
Japanese Patent JP4543560
Kind Code:
B2
Abstract:
An image input device comprising a transparent substrate, a plurality of light emitting means arranged on one surface of this transparent substrate, a plurality of photoelectric conversion means arranged on the above one surface of the transparent substrate, and a light switching means disposed on the other surface of the transparent substrate, for selectively reflecting or transmitting light emitted from the light emitting means. The light emitting means emits light toward the above other surface of the transparent substrate, and the photoelectric conversion means detects light incident on the toe above one surface, and allows, when an image is to be input, the light emitting means to emit light toward the above other surface of the transparent substrate and the light switching means to be set to reflect the above light so that the photoelectric conversion means receives a reflection light from the image. When an image is to be displayed, the light switching means is set to transmit the light and allows the light emitting device to emit light toward the above other surface of the transparent substrate as required by the image.
