A cleaning device comprises a cassette housing 300 and a cleaning ribbon 318 mounted on spools within the housing. With the housing inserted into a video unit, the guide members of the unit move the cleaning ribbon outwardly into an engaged position to clean the operating components of the video unit. The housing has a first opening 312 in a forward portion to expose a first portion of said ribbon so that said ribbon can be engaged by said guide means and extended from said housing to its cleaning position, in such a manner that a cleaning second portion 378 of said ribbon is moved into engagement with at least the transducing head, said housing having a second opening 348 through which a cleaning material can be applied to said second ribbon portion when the ribbon is in its retracted position. <IMAGE> |
