Therefore, air mixed with foreign matter such as dirt and dust from the environment in which the computer is placed passes through the inside of the disk device, causing foreign matter such as dust to adhere to the head 24 of the disk device 12 and the drive mechanism (not shown). It had some drawbacks such as being stowed away.

The present invention has been made to eliminate the above-mentioned drawbacks, and is intended to prevent foreign matter such as dust from getting into the head or drive mechanism of a disk device without interfering with the ventilation function of the computer main body in which a recording or reproducing device such as a disk device is installed. The object of the present invention is to provide a disk device that is less susceptible to intrusion.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a recording or reproducing apparatus equipped with a head that performs recording or reproduction on a recording medium inserted into the apparatus. When forming an air flow within the device by forming an air intake port that takes in air from the outside and an air outlet that discharges the air that has flowed in from the air intake port, the center of the air flow is located in the recording medium. A configuration is adopted in which the air inlet and the air outlet are formed so that the air does not pass through the exposed portion of the medium and the head.

[Function] In this configuration, air is sucked in from the disc insertion/exhaust port at the front of the computer by exhausting air using the fan at the rear of the computer, but in the case of a disc device used as a recording or playback device, the insertion slot is open. The others have only an open air outlet window near the disk insertion slot, and the others have a sealed structure, so the air taken in from the disk insertion slot is exhausted from the rear of the computer through this air outlet. At this time, it does not pass along the head and drive mechanism.

[Example] Next, the present invention will be described in detail using an example shown in the drawings.

Figures 1 and 2 are for explaining one embodiment of the present invention, and the same or corresponding parts as in Figures 4 and 5 are given the same reference numerals, and their explanations are omitted. .

The disk device 12 shown in FIG. 1 is formed in the shape of a casing as a whole, and the front surface of the case 26 is closed by a front panel 30 having a disk insertion slot 28, and one side of the case 26 is closed. front panel 30
An air window 32, which is an open portion, is formed nearby.

Note that the reference numeral 34 is an eject button for inserting the disk cassette 20.
