Abstract

PURPOSE:To remove dust stuck on the magnetic surface of a magnetic tape, by providing a cleaner main body holding two or more cleaner chips which are brought into contact with the full width of the magnetic surface in the vicinity of a reel inside the case of a cartridge magnetic tape. CONSTITUTION:The device is provided with at least two or more cleaner chips 5a and 5b which are positioned to the vicinity of a reel 2 inside the case of a cartridge magnetic tape and brought into contact with the full width of the magnetic surface of a tape 6, a cleaner main body 5 which holds the cleaner chips 5a and 5b, and a leaf spring 7 which is positioned to the opposite side of the cleaner chips 5a and 5b, with one end being engaged with the cleaner main body 5 and the other end being fixed to the side 3a of the case of the cartridge magnetic tape. Therefore, dust stuck on the magnetic tape 6 is removed by the tape cleaner 5 regardless of the running of the magnetic tape 6 in the forwarding or reverse, direction and the magnetic tape 6 slid on a magnetic head is always kept in a clean state. Accordingly, a better cleaning effect can be obtained and the service life of the magnetic tape 6 can be also be extended.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cartridge magnetic tape, and more particularly to a cartridge magnetic tape having a cleaning function for the magnetic surface of the magnetic tape.

[Conventional technology]

Conventional cartridge magnetic tapes of this type do not have a function to remove dust adhering to the magnetic surface of the tape inside the main body, and dust may adhere to the running surface of the magnetic head of the cartridge magnetic tape device. , it has the disadvantage of causing errors during writing and reading.

[Problem that the invention seeks to solve]

The problems to be solved by the present invention are as described above, in the conventional cartridge magnetic tape, it is not possible to remove the dust when the tape is running, and the problem is that the damage and deterioration of the tape due to the dust is accelerated. Therefore, it is an object of the present invention to provide a magnetic tape cartridge which eliminates the above-mentioned drawbacks, eliminates particles deposited on the magnetic surface of the tape, and extends the life of the tape.

[Means for solving problems]

at least two cleaner chips located near the reel in the case of the cartridge magnetic tape and in contact with the entire width of the magnetic surface of the tape; a cleaner body holding the cleaner chips; and one cleaner chip located opposite the cleaner chips. One end portion engages with the cleaner body, and the other end portion includes a leaf spring fixed to the side surface of the case of the cartridge magnetic tape.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows the entire magnetic tape as an example of the magnetic tape of the present invention, and FIG. 2(a) is an enlarged view of the tenth main part A. Figure 242(b) is an enlarged view of the main part A in Figure 1.
The state of the tape 71 on the supply reel 2 when there are four windings is shown.

In FIG. 1, 2E4, the tape cleaner main body 5 is
The cartridge is located near the supply reel 2 inside the magnetic tape main body 1, and is located in the center between the walls of the case 3 and the base plate 4 so as to be in contact with the magnetic surface 11 of the tape 6. The tape cleaner body 5 also has a tape 6 at the end.
two edge-shaped cleaner chips 5 that contact the magnetic surface of the
a and 5b, the other end engages with a leaf spring 7, and the leaf spring 7 is structured to be fixed to the side plate 3a of the case 3.

The operation of this embodiment will be explained. Cartridge magnetic tape body 1 set in a cartridge magnetic tape device
In this case, when the supply reel 20 is fully wound as shown in FIG. 2(a)K, the tape cleaner main body 5 is in contact with the tape in a compressed state in the direction of the arrow 12. As the tape 6 travels in the direction of the arrow 10, the cleaner chip 5a made of a highly hard material removes dust attached to the tape 6. As the tape on the supply reel 2 decreases, the tape cleaner main body 5 is pushed in the direction of the arrow 13 by the leaf spring 7 and constantly contacts the tape magnetic surface, and as shown in FIG. The dust continues to be removed until the tape 6 reaches the minimum tape (detected as the final tape).

When the tape 6 is rewound in the direction of the arrow 11, cleaning is also carried out by performing the reverse operation.

〔Effect of the invention〕

As explained above, when the cartridge magnetic tape of the present invention is used, the dust adhering to the magnetic tape is removed by the tape cleaner regardless of whether the magnetic tape is running forward or backward, and the magnetic head is Sliding magnetic tape can always be slid in a clean state and has an excellent cleaning effect. Furthermore, the life of the magnetic tape can be extended.
