摘要： A laser beam emitted from a semiconductor laser is guided to a sensitive recording medium on a drum by a focusing optical system and an optical anisotropic element. The optical anisotropic element separates the laser beam along its optical axis to produce a laser beam having two focused positions for thereby increasing the depth of focus. With the increased depth of focus, it is possible to record a highly accurate image on the sensitive recording medium even if the sensitive recording medium is displaced because the drum has its outer circumferential surface not concentric with its axis or the sensitive recording medium is lifted off the drum.

摘要： A photographic printer has a first polarizing beam splitter for splitting light from a light source into a first polarized light and a second polarized light. The first polarized light passes through a first liquid crystal cell having a liquid crystal material held between grid-like transparent electrodes. At this time, the plane of polarization of the first polarized light is changed in each small region formed in the liquid crystal cell. The first polarized light then enters a second polarizing beam splitter. On the other hand, the second polarized light enters the second polarizing beam splitter after its plane of polarization has been changed. At the second polarizing beam splitter, the first polarized light and the second polarized light are combined and then projected on a print paper via a photographic film so that an image recorded on the photographic film is exposed and printed on the print paper. Accordingly, the time required for exposure can be shortened compared to conventional photographic printers using polarizing plates.

摘要： A photographic printer has an exposure station, in which a frame of a photographic film and color photographic paper are set. A light source is disposed in opposition to the color paper with reference to the photographic film set in the exposure station, and constituted by LED elements. The LED elements are disposed in a matrix for emitting light of red, green and blue colors. The light source illuminates the frame from behind. The color paper is exposed by the light transmitted through the frame, to print the frame recorded on the photographic film to the color paper. In a preferred embodiment, a drive signal is determined individually for driving respective the LED elements. The drive signal is applied to the respective LED elements.
