Abstract
An apparatus has LCD 13, a photosensitive material holding device that holds photosensitive material 21 on the back of the LCD, first shutter device 20 that can let through and block light from the LCD to the photosensitive material, and second shutter device 19 that blocks infiltration of external light by covering the display surface of the LCD during exposure. In addition, guiding device 18 that conducts the display light of the LCD to the photosensitive material and exposure light source 17 for the LCD also may be installed. Furthermore, apparatuses are disclosed that have a display window in which the LCD can be placed and a device that shields the display window, and support the LCD within a housing such that it rotates freely between a display position in which its display surface faces the display window and an exposure position in which its display surface faces the photosensitive material. The invention enables print output of display data on a liquid crystal display without damaging the portability of various types of portable electronic devices such as electronic cameras, data terminals, or portable telephones.
