Inoue's invention relates to a magnetic head device which is built, for instance, in
a tape recorder and has an automatic cleaning mechanism. As best shown in Figure 4,
the cleaning mechanism includes (1) a movable inverted-L-shaped lever 4 comprising a
horizontal arm 4h and a vertical arm 4v, and (2) a brush 4e attached to the vertical arm
4v. The brush 4e is formed as follows: A bar, around which fibers such as Nylon fibers
and carbon fibers are wound, is fixedly held on the vertical arm 4v, for instance, by
caulking. The use of the brush 4e of carbon fibers contributes to prevention of the
occurrence of static electricity.
