Abstract
The cleaning cassette is intended to clean signal heads in systems operated with magnetic tape cassettes, for example, in cartridge tape recorders, and is provided with a cleaning element (18) which mechanically acts upon the parts to be cleaned. In order to impregnate the cleaning element, preferably a driven cleaning tape (18) with cleansing fluid directly during the cleaning operation, the housing (10) of the cassette is provided with a cavity (12) designed for receiving the cleansing fluid. The said fluid is fed through a batching means (16) via an outlet valve (40) to the cleaning tape (18). The batching means (16) and the outlet valve (40) will supply the cleaning tape (19) with cleansing fluid only if the same has been circumferentially driven by the driving mechanism (58, 72) of the system. The cleaning tape (18) impregnated with cleansing fluid will thereupon get into contact with the signal heads (56) and the parts of the driving mechanism (58, 72) to be cleaned.
