PURPOSE:To effectively perform dustproofing by possessing a flexible print board printed with a signal conductor for transmitting a signal based on a result of a detector to an actuator and covering a movable part with this print board. CONSTITUTION:A base of the movable part for moving a medium to a recording position, i.e. a carriage 11 is the flexible print board for transmitting a driving signal, etc., from a CPU to the actuator, etc. This flexible print board 11 is formed likely in a shape of enclosing the carriage, and is fitted to the carriage, spreading over a spot facing part 16. Then, the print board 11 is processed by cutting in order not to allow the print board 11 to obstruct an optical path of a light beam. Thus, since the movable part is blocked in its dust entering hole by using the flexible print board, the dustproof of a mirror part can effectively be performed without adding any parts. |
