    摘要: The present invention relates to a print head (3) including an illuminator (5) for emitting light in a line extending in a primary scanning direction, a liquid crystal shutter (6) for selecting whether or not light traveling from the illuminator (5) is allowed to pass, and a light emitting portion (323) for emitting light traveling from the liquid crystal shutter (6) toward a photosensitive recording medium (22). The liquid crystal shutter (6) includes a plurality of individual shutter portions aligned in the primary scanning direction, for example. Preferably, each of the shutter portions is capable of individually selecting whether or not the light traveling from the illuminator (5) is allowed to pass.
