<p>PURPOSE:To attain the highly accurate carrying wide sub-scanning of sheet matters by separating a pair of feed rolls from a sheet matter when a sheet matter like a film, etc., is held between a pair of carrying rolls. CONSTITUTION:When the edge part of a film F reaches a main scanning position of the laser light L, an optical part 24 is driven to make the light L irradiate a prescribed area of the film F in the main scanning direction to start a picture recording action to the film F. When the edge part of the film F is set between rolls 164a and 164b, the roller 164a is approximated to the roll 164b and the film F is held between pairs of rolls 162 and 164. When the film F is held between the pair of rolls 164, the roll 162a of the pair of rolls 162 is separated from the roll 162b. The carrying while sub-scanning of the film F is executed by the pair of rolls 164.</p> |
