Abstract

En rensekassett for kassettbåndopptakere omfattende et renseelement som ved plassering av kassetten i båndopptakeren, settes i inngrep med dennes opptaker-/kopieringshode og som via en overførings-anordning er koblet til en effektiv spoledrivaksel i båndspilleren for å gi renseelementet en frem- og tilbakesveipende bevegelse langs lydhodet ved hjelp av rotasjon av spoledrivakselen. Overføringsanord-ningen omfatter to gjensidig festede drevne tannhjul (14, 16), hvorav det ene bærer det eksentriske hodet (8) som ved hjelp av en svingarm (5) gir renseelementet (1) frem- og tilbakebeveg-elsen. Nevnte drevne tannhjul (14, 16) er arrangert for å brukes i en enveis-koblingsforbidelse med henholdsvis et første og andre drev (12, 13) som individuelt er anordnet aksialt flyttbart på et gjenget navorgan (10, 11) som står i inngrep med en spoledrivaksel, for derved å tillate bevegelse mellom posisjoner i hvilke drevet (12, 13) henholdsvis er/ikke er i inngrep med det drevne tannhjul. Uansett hvilken av navorganene (10, 11) som er koblet til den virkende spoledrivakselen, oppnås en korrekt rensefunksjon uten etablering av noen drivforbidelse med det andre navorgan via rensekassetten.A cleaning cassette for cassette tape recorders comprising a cleaning element which, when placing the cassette in the tape recorder, is engaged with its recorder / copying head and which via a transfer device is connected to an efficient spool drive shaft in the tape player to give the cleaning element a reciprocating movement. the sound head by means of rotation of the spool drive shaft. The transfer device comprises two mutually fastened driven gears (14, 16), one of which carries the eccentric head (8) which by means of a pivot arm (5) gives the cleaning element (1) the reciprocating movement. Said driven gears (14, 16) are arranged for use in a one-way coupling connection with a first and a second gear (12, 13), respectively, which are individually arranged axially movable on a threaded hub member (10, 11) which engages a spool drive shaft, thereby allowing movement between positions in which the gear (12, 13) is / is not engaged with the driven gear, respectively. Regardless of which of the hub means (10, 11) is connected to the acting coil drive shaft, a correct cleaning function is achieved without establishing any drive connection with the other hub means via the cleaning cassette.
