Abstract

PURPOSE:To remove dust securely, by providing a projection part for cleaning which is in contact with a magnetic sheet on the internal surface of the case of a magnetic cassette sheet, and allowing dust collected by the projection part to stick to a cohesive member. CONSTITUTION:Center holes 2 are formed at the center parts of half cassettes 1a and 1b superposed one over another to form a flat enclosure; and index windows 3 are formed with the center holes between and a head window 3 wherein a magnetic head is fitted is formed in a perpendicular direction. A magnetic sheet 7 is provided between the upper and lower cassette halves. On the reverse surface of the cassette half, the projection part 8 for cleaning is formed in a radius direction where it is opposed to and in contact with the magnetic sheet 7. The cohesive member 9 is arranged on the cassette side closely to the projection part in the outward direction. Consequently, collected dust is projected out to be removed securely.

Furthermore, a rad window 4 into which a magnetic head is fitted is formed on the front end side of the magnetic sheet cassette 1 in the mounting direction. On the opposite side of the head window 4 and the center hole 2 (the second is a side display section 5 on which a label indicating whether the magnetic sheet is side A or side B is pasted) is formed as a lowered recess. .

On the other hand, on the back side of cassette 8-) la, lb, magnetic sheet 7
At a position facing the magnetic sheet 7, a cleaning protrusion 8 is provided to protrude substantially along the radial direction at a position in contact with the magnetic sheet 7. As is clear from FIG. 2, this protrusion 8 is arranged so that its axial direction intersects a straight line l passing through the center of the magnetic sheet cassette 1 at a predetermined angle θ.

The reason for this arrangement is that if the magnetic sheet cassette 1 is arranged on the straight line l passing through the center of the magnetic sheet cassette 1, the dust collected from the magnetic sheet 7 by the protrusion 8 will come into contact with the protrusion 8 at right angles. This is because the particles accumulate in this area. Therefore, if the protruding part 8 is arranged so as to intersect the straight line l at an angle of θ, the collected dust (
On the other hand, a component force is generated outward of the magnetic sheet cassette 1, and a force is applied to push the dust outward (in the negative direction).

As is clear from the above explanation (= a protrusion for cleaning that comes into contact with the magnetic sheet is provided on the inner surface of the case of the magnetic sheet cassette, and the dust collected by the protrusion is guided to the adhesive member and attached thereto). Because of this structure, there is an excellent effect that the collected dust can be removed reliably without being rubbed against the magnetic sheet again and adhering to it.
