As shown in FIG. 4A, when dust floating in the air enters the housing 2 through the gap between the holes 201 and 202 and accumulates on the spindle motor 6 and the pickup driving unit 8, First, the knob 401 of the slide portion 4 is pulled out to open the side holes 203a and 203b. Next, for example, the side holes 20 are formed by air spray.
Air is injected from 3a toward the inside of the optical disc reproducing apparatus 1. Then, as shown in FIG. 4B, dust 1 deposited on the spindle motor 6 and the pickup driving unit 8 is removed.
2 is generated by air injected from the side hole 203a.
It is removed from the side hole 203b to the outside of the optical disc reproducing device 1. As described above, in the optical disc reproducing apparatus 1 of the present embodiment, even if the dust 12 accumulates on the spindle motor 6 and the pickup driving section 8, the knob 401 of the slide section 4 is slid forward and the side hole 203a After the dust is released from the side holes 203a and 203b, the accumulated dust 12 can be easily removed. When the optical disk reproducing apparatus 1 of this embodiment is used normally, as shown in FIG. 1, the knob 401 must be pushed backward until the rear surface of the slide portion 4 comes into contact with the front surface of the housing 2. Since the side holes 203a and 203b are closed by the side panels 402a and 402b, dust floating in the air is removed from the side holes 203a and 203b.
b, dust 12 can be prevented from entering the housing 2 and accumulating on the spindle motor 6 and the pickup drive unit 8. In the optical disk reproducing apparatus 1 of the present invention, the slide motor 4 is pulled out forward and air is jetted from the side holes 203a and 203b of the housing 2 by an air jet machine such as an air spray. Although the configuration is such that dust accumulated in the driving unit 8 is removed, a configuration may be employed in which a fan that sends air into the optical disc reproducing apparatus 1 is provided in the side hole 203a. In this case, when it is detected that the slide portion 4 has slid forward, the air of the fan passes through the inside of the housing 2 from the outside of the side hole 203a and flows to the outside through the side hole 203b. The entered dust is removed to the outside of the side hole 203b. As a result, the dust 12 can be prevented from being deposited on the spindle motor 6 and the pickup driving unit 8 only by pulling the knob 401 forward without using air spray. According to the present invention, it is possible to provide an optical disk reproducing apparatus capable of easily removing dust accumulated inside the housing.
