<p>PURPOSE:To make it possible to transport a light sensitive element continuously and at constant speed by providing a tricolor division crystalline liquid shutter between a spherical lens and a focus. CONSTITUTION:A white light is linearly converged to a focus F by a cylindrical lens. A tricolor division crystalline liquid shutter 3 receives a color selection signal from a crystalline liquid drive circuit 8. Consequently, the crystalline liquid shutters 3r, 3g, 3b are opened by their specified times in that order, and the white light reaches a focus F, passing through R.G.B color filters. A crystalline liquid shutter array 4 receives an image signal form the crystalline liquid drive circuit 8 synchronized with the transmission time of each color light and opens at an element position for each color for required exposure time. Then the array allows line dot red, green and blue lights to pass toward light sensitive paper 5. In this case, the light sensitive paper 5 is fed continuously and at constant speed in synchronization with a time required for transmission of a single line of image signal.</p> |
