Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning device (cleaning device) for a magnetic head mounted on a rotating cylinder of a home video tape recorder (hereinafter referred to as VTR).

[Conventional technology]

The conventional device has a structure including one cleaning member for cleaning the rotating magnetic head, as described in Japanese Patent Application Laid-Open No. 1-282716. FIG. 3 shows a conventional example. Reference numeral 1 denotes a rotating shilling equipped with a magnetic head 1a, which rotates counterclockwise. A shaft 14 is provided at one end of the lever 5, and a cleaning member 13 is attached thereto. A springette 17 is attached to the other end of the lever 5, and the lever 5 rotates about the fulcrum 16 by the biasing force of the spring 17, causing the cleaning member 13 to come into contact with the magnetic head 1a of the rotary sill 1. Perform head cleaning.

[Problem to be solved by the invention]

However, since there are many types of stains on magnetic heads, such as adhesion of foreign matter and adhesion of tape magnetic powder, the conventional technology mentioned above, which uses a single cleaning member, may not be able to remove the stains due to the shape and characteristics of the cleaning member. Therefore, there were problems such as it took a long time to remove the dirt and it was not possible to completely remove the dirt. SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning device that compensates for the above-mentioned disadvantages of the cleaning member and improves the dirt removal effect.

[Means to solve the problem]

In order to achieve the above object, the present invention uses two cleaning members and has a configuration in which both of them come into contact with the magnetic head, thereby improving the effect of removing Ghent dirt. Also, 2
By configuring the individual cleaning members with different materials, the dirt removal effect is improved.

[Effect]

With this configuration, the two cleaning members can come into contact with the magnetic head of the rotary cylinder, increasing the dirt removal power, shortening the dirt removal time, and keeping the magnetic head surface clean at all times.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings (FIGS. 1 and 2).

In the figure, reference numeral 4 denotes an arm that is connected to one end of the lever 5 by a link pin 7, and a shaft 9 is attached to this arm 4.
10, and the cleaning members 2, 3 are attached to the shafts 9, 110.
is installed. - At the other end of the lever 5 which rotates around the fulcrum 6, there is a screw 8 which urges the cleaning members 2 and 3 in the direction of contacting the rotating cylinder 1 via the lever 5 and the arm 4. Since they are connected, when the lever 5 rotates around the fulcrum 6 towards the rotating cylinder due to the force of the spring 80, the arm 4 also moves towards the rotating cylinder 1, and the cleaning members 2 and 3 rotate with the rotating ram 11. The fixing member 1 to the ram 12 are in contact with each other, and the magnetic head 1a is cleaned using two types of cleaning members, for example, one type is a semi-synthetic fiber sheet, and the other type is a string abrasive paper or the like. I can do it.

〔Effect of the invention〕

As described above, according to the present invention, since the magnetic head can be cleaned using two cleaning members or two types of cleaning members, dirt can be removed from the magnetic head in a short time, and the surface of the head can be cleaned. It can always be kept in a clean condition.
