<p>PROBLEM TO BE SOLVED: To finish exposure through single relative movement of a head and a recording medium by emitting light from a light source while switching a filter through rotation. SOLUTION: Based on a filter position signal from a photosensor 23, the timing for locating a specific filter [red(R), green(G), blue(B)] on an optical path 16 is detected and a light source (fluorescent light emitting tube 2) is driven with an image signal corresponding to the transmitting color of the filter (R, G, B). The light passes through the filter (R, G, B) and enters into a recording medium (film 3). The operation is conducted in specified order for R, G, B and the film 3 is irradiated repeatedly. For example, each color filter is turned by 60 deg. for writing a line in the main scanning direction onto the film 3 and the rotary filter section 15 is turned by 180 deg.. The film 3 is moved intermittently, for example, every time when a line is written and moved in the sub-scanning direction at the timing of irradiating dot-like light of RBG thus recording an image on the entire surface of the film 3.</p> |
