<p><P>PROBLEM TO BE SOLVED: To provide an optical print head which can make a focus adjusting mechanism thin. <P>SOLUTION: This optical print head is equipped with an LED array 3, a lens array 6, and the focus adjusting mechanism 10 which carries out focusing by adjusting a position in a Z direction of the lens array 6. The focus adjusting mechanism 10 includes at least a movable member 11 arranged movably in the Z direction in a state of coupling with the lens array 6, an adjusting belt 12 which adjusts a movement amount in the Z direction of the movable member 11, and a gear 13 which transmits a driving force from the adjusting belt 12 to the movable member 11. The driving force is transmitted from the adjusting belt 12 to the movable member 11 via the gear 13 by moving the adjusting belt 12 in a Y direction, whereby the movable member 11 is moved in the Z direction. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
