    摘要: A backlight emits diffused light beams. An emission direction characteristic-forming plate allows light beams which have been incident thereon at generally right angles therewith to pass therethrough and intercepts light beams which have been incident thereon obliquely. An image display/input panel has light receiving elements each incorporated in a corresponding pixel having a liquid crystal cell. In an image input operation, pixels are sequentially turned on and off so as to scan an original document by parallel light emitted vertically from a turned-on pixel. Light reflected by the original document is received by the light receiving element incorporated in the turned-on pixel and converted into an electric signal. Light emitted from the turned-on pixel of the image display/input panel and reflected by the original document is received by only the turned-on pixel. In this manner, a high resolution can be obtained in the image input operation.

    摘要: A printer film carrier turning apparatus for obtaining a photograph by irradiating light onto a film comprises a film carrier for supporting the film, a carrier supporting table for supporting the film carrier parallel with the film to make the film carrier turn through a 90.degree. range, and a light diffusion box for diffusing illuminance light to uniformly illuminate a film range which is to be printed. The film turning apparatus is constructed such that the film carrier turns in unison with the light diffusion box. Therefore, transferring rollers of the film carrier cannot interfere with the light diffusion box, which allows the light diffusion box to be placed very close to the film carrier and thereby increases the efficiency of the light source. Also, the film carrier can be turned in unison with the light diffusion box, thereby improving the operating mechanism.
