[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus having a rotary magnetic head, and more particularly to a cleaning mechanism for the rotary magnetic head.

[0002]

2. Description of the Related Art An example of a conventional cleaning mechanism for a rotary magnetic head is shown in FIGS. 8 and 9
The above configuration is a configuration example of a cleaning mechanism using two rollers. 8 and 9, a roller surface cleaning roller 10 as a roller surface cleaning member for cleaning the roller surface of the cleaning roller is rotatably engaged with a shaft 20 fixed to the chassis 8.
The roller surface cleaning roller 10 is generally made of a soft material such as urethane foam or felt, and has a surface coated with an adhesive material. On the other hand, the cleaning roller 5
Is rotatably engaged with the shaft 6 on the drive arm 7 and is movable by the drive arm 7 with respect to the chassis 8 in the direction of arrow 17. When cleaning the rotary magnetic head 3, the cleaning roller 5 moves to the drum device side and contacts the rotary magnetic head 3, the rotary drum 1, and the fixed drum 2. In this contact state, the cleaning roller 5
The rotary head 1 is rotated around the shaft 6 by the rotational force of the rotary drum 1 to clean the rotary head 3. Cleaning of the rotary magnetic head 3 is performed, for example, during a tape loading period. That is, during the loading period, the drive arm 7 is moved closer to the drum device to bring the cleaning roller 5 into contact with the rotating rotary magnetic head 3, the rotary drum 1, and the fixed drum 2, and at least the surface of the rotary magnetic head 3 is covered. The foreign matter 13 such as magnetic powder or dust is moved to the surface side of the cleaning roller 5. After performing the operation for a predetermined period, the cleaning roller 5 is retracted from the drum device by the drive arm 7, and the cleaning operation of the rotary magnetic head 3 is completed. In the cleaning operation, the cleaning roller 5 moves with respect to the roller surface cleaning roller 10 between the time when the cleaning roller 5 approaches the drum device and the time when the cleaning roller 5 retreats from the drum device, that is, the cleaning roller 5 moves toward the drum device. When it is not in contact with the roller surface cleaning roller 10, it comes into contact with the roller surface cleaning roller 10. By the contact, the foreign matter 13 on the surface of the cleaning roller 5 moved from the rotary magnetic head 3 side in the cleaning operation is moved to the surface side of the roller surface cleaning roller 10. Japanese Patent Application Laid-Open No. 8-329427 describes a head cleaning mechanism having the above configuration. Further, FIG. 10 shows an example of a head cleaning mechanism in which one roller and a scraper as a roller surface cleaning member are combined. In FIG. 10, the cleaning roller 5 moves to the drum device side by the movement displacement of the drive arm 7, contacts the rotary magnetic head 3 and the rotary drum 1, and moves at least the foreign matter 13 on the surface of the rotary magnetic head 3 to the roller surface. Let After a predetermined period of time, the cleaning roller 5 is moved from the drum device side to the scraper 22 side by the drive arm 7, and the contact state with the rotary magnetic head 3 and the rotary drum 1 is released, and the tip of the scraper 22 is released. The roller surface comes into contact with the portion. Due to the contact, the foreign matter 13 on the roller surface is scraped off. Japanese Patent Laid-Open No. 8-194923 discloses a head cleaning mechanism having the above structure.
