Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head peripheral cleaning device for a magnetic recording / reproducing apparatus, and in particular, a cleaning member simultaneously cleans a magnetic head surface and a negative pressure slider surface as a magnetic disk cassette is inserted and ejected. The present invention relates to a head cleaning device.

2. Description of the Related Art A recording / reproducing apparatus using a magnetic disk as a recording medium is widely used in personal computers, word processors, and other electronic still cameras.

For example, in a magnetic recording / reproducing apparatus of an electronic still camera, a magnetic disk cassette is inserted from an insertion opening to operate a disk cassette ejecting mechanism so that the disk is drawn into the apparatus and automatically stored at a recording / reproducing position. There is a so-called slot-in type configuration. Conventionally, a head cleaning device for cleaning the head surface of a magnetic head by utilizing the insertion / ejection operation of the magnetic disk cassette to provide a special movable member on the disk insertion path and integrally provide a cleaning member on the movable member. It has been proposed (Shokai Sho 57-168838).

[0004]

However, in the above-described head cleaning device provided with the special movable member, the special movable member is provided only for cleaning, so that the structure is complicated and the device is miniaturized. However, it was inconvenient for the price reduction. Furthermore, only the cleaning of the head surface is considered as the object to be cleaned, and in reality, dust and dirt are collected on the negative pressure slider surface provided around the head to stably contact the head with the disk-shaped magnetic disk. However, there is a problem that the magnetic disk is damaged.

It is an object of the present invention to propose a cleaning device for the peripheral portion of the head, which is capable of cleaning both the head surface and the negative pressure slider surface at the same time and has a compact movable member.

[0006]

SUMMARY OF THE INVENTION The present invention is a slot-in type magnetic recording / reproducing apparatus equipped with a magnetic disk cassette, a magnetic head, and a negative pressure slider for bringing the head into stable contact with a disk-shaped magnetic disk. A rotatable cleaning member is provided on the upper surface of the disk cassette holder, and the cleaning member is rotated by inserting and ejecting the magnetic disk cassette to simultaneously clean the magnetic head surface and the negative pressure slider surface.

According to another aspect of the present invention, there is provided a slot-in type magnetic recording / reproducing apparatus equipped with a magnetic disk cassette, a magnetic head, and a negative pressure slider for stably contacting the head with a disk-shaped magnetic disk. A cleaning member is provided on the disk cassette discharge lever, and the cleaning member cleans the magnetic head surface and the negative pressure slider surface at the same time by the movement of the disk cassette discharge lever accompanying the insertion and discharge of the magnetic disk cassette. ing.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are schematic diagrams showing a schematic configuration of a first embodiment of the present invention.

FIG. 1 is a perspective view showing the main structure, FIG. 2 (A) is a schematic sectional view after the insertion of the magnetic disk cassette in FIG. 1 is completed, and FIG. 2 (B) is the insertion of the magnetic disk cassette. It is a schematic sectional drawing which shows the state in the middle of discharge.

In the figure, a disk cassette 2 containing a magnetic disk 1 is inserted into a cassette insertion / ejection port 4 of a magnetic recording / reproducing apparatus main body 3 for recording or reproduction, and is ejected when not in use. Here, a rotatable rotating member 7 is provided on the chassis portion forming the upper surface of the disk cassette holder 5 built in the magnetic recording / reproducing apparatus main body 3, and the rotating member is provided when the disk cassette 2 is inserted or ejected. When the rotating member 7 is rotated, the surfaces of the magnetic head 11 and the negative pressure slider 12 with respect to the magnetic disk 1 are cleaned by the cleaning member 7a attached to the tip of the rotating member 7.

Here, the rotating shaft 7b of the rotating member 7 is rotatably supported at both ends by a supporting portion 6 provided on the disc cassette holder 5. Further, the rotating member 7 is pressed against a stopper portion 9 provided on the upper surface chassis portion of the disc cassette holder 5 by a spring 8, and is stationary in the state of FIG.

Next, the operation of inserting and ejecting the disc cassette will be described. When the disc cassette 2 is inserted, the rotating member 7 rotates counterclockwise in FIG. 2B at the end surface 2a of the disc cassette 2, and the cleaning member 7a moves together with the magnetic head 11 and the negative pressure slider. When the surface of the magnetic disk 1 of 12 is cleaned and then the insertion of the disk cassette 2 is completed, as shown in FIG. 2A, the rotating member 7 is pushed to the upper side of the disk cassette 2.

When the disc cassette 2 is ejected,
The spring 8 rotates clockwise in FIG. 2 (A), and the cleaning member 7 a moves with the rotation of the magnetic head 11 and the negative pressure slider 12.
The surface of the magnetic disk 1 against the magnetic disk 1 is cleaned, and the apparatus is stopped in the state of FIG.

Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a schematic configuration diagram of the second embodiment of the present invention, and the portions having the same configurations as those in FIG. The upper surface portion of the disc cassette holder 5 is omitted, and a discharge lever 15 for the disc cassette 2 having a shaft 16 as a fulcrum is provided on the bottom portion of the disc cassette holder 5, and the disc cassette 2 is inserted and ejected. The cleaning member 15a attached to the tip of the ejection lever 15 brushes and cleans the surfaces of the magnetic head 11 and the negative pressure slider 12 with respect to the magnetic disk 1 as the ejection lever 15 rotates.
Here, when the disc cassette 2 is ejected, the ejection lever 15 is rotated from the B position to the A position by the spring 17 and pressed against the stopper portion 18, and is stationary at the position A in FIG.

Next, the operation of inserting and ejecting the disc cassette will be described. When the disk cassette 2 is inserted, the ejection lever 15 is pushed by the end surface 2a of the magnetic disk 2 in the counterclockwise direction in FIG. 3, and the cleaning member 15a and the magnetic head 11 and the magnetic head 11 are moved in the middle of the movement along with the rotation. The surface of the pressure slider 12 with respect to the magnetic disk 1 is cleaned, and the pressure slider 12 stands still at the position B in FIG.

When the disc cassette 2 is ejected, the ejection lever 15 is rotated clockwise by the spring 17 in FIG.
The disk cassette 2 is moved so as to be pushed out, and the cleaning member 15a cleans the surfaces of the magnetic head 11 and the negative pressure slider 12 with respect to the magnetic disk 1 during the movement, and is stopped by the stopper portion 18 to be in the position A of FIG. To stand still.

In this embodiment, the cleaning member has a brush shape, but may be any member having a cleaning effect such as a felt shape.

[0018]

As described above, according to the present invention, both the magnetic head surface and the negative pressure slider surface can be cleaned at the same time when the magnetic disk cassette is inserted and ejected, without the user having to bother. Can be cleaned at all times. In addition, the structure is compact and does not consume power. In particular, cleaning the surface of the negative pressure slider where dust and dirt are likely to collect is effective in preventing scratches and damages on the magnetic disk.
