PURPOSE: An optical apparatus is to spout an air by an air providing unit operated with a media transmission unit and prevent lying of a dust on a pick-up lens for basically overcoming a reproducing operation fault. CONSTITUTION: An optical apparatus comprises: a media transmission unit(T); an air providing unit(200) for operating with the media transmission unit(T) including a cylinder unit(210) installed in a main body, a piston arbor(220) and a piston plate(230) to be installed in the cylinder unit(210) and to be geared and installed with the media transmission unit(T), a left and right side inhaling hole(211) to be formed at one side of the cylinder unit(210), and a shield unit(240) for preventing an inhaled air through the left and right side inhaling hole(240); and a spouting unit(300) for spouting an air according to the air providing unit(200). Since the generated operation fault is basically overcome, the pick-up lens having a clean stage is maintained.
