Claims

[Scope of utility model registration request]

(1) In a case formed by combining a first half and a second half having substantially the same external shape as the cartridge, the cartridge is installed in a deck and rotates by being transmitted with the rotation of the capstan on the deck side. A swinging arm of a cartridge type cleaning pack, which is provided with a rotating member that rotates, and a swinging arm member that swings as the rotating member rotates to reciprocate a cleaner member attached to a magnetic head and a sensor on the deck side. The mechanism includes a plurality of protrusions integrally formed on one surface of the rotating member, rotatably supported on the first half, and on the inner surface of the second half. A cartridge type having a structure in which a protrusion is formed and the swing arm member is intersectingly sandwiched between the protrusion of the rotating member on the first half side and the protrusion of the second half. Cleaning pack swing arm mechanism.

(2) The rotating member integrally has a radial protrusion on the other surface, and the first half integrally has a substantially circular protrusion concentric with the rotating member on the inner surface. A swing arm mechanism for a cartridge type cleaning pack according to claim (1) of the registered utility model.
