<p>1,082,523. Feeding record tapes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 8, 1965 [Jan. 11, 1964], No. 939/65. Heading G5R. A tape is continuously lapped, without relative movement, about a cylindrical processing station 3 by an arm 4 which causes rollers 12, 12<SP>1</SP>, 13, 13<SP>1</SP> to execute planetary movements about the station 3, the tape being unwound from a coil 1 and taken up on a coil 2. A motor 14 drives the arm 4 and a motor 15 drives the coils 1, 2 through a differential 16 to maintain tape tension. A rubber roller 8 holds the tape stationary on the surface 9 which may take the form of a stationary sprocket engaging holes in the tape. Where the tape is a punched paper one, the surface 9 may contain punches or feeler-type reading devices coacting with the roller 8. Where the tape is a magnetic one, the surface 9 may be circumferentially slotted to accommodate a wheel-mounted read/write head moving differentially of the other members. Preferably (though the arrangement is not detailed), one of the coils 1, 2 is wound inside out, so that the winding diameters of the two coils, though varying, are kept substantially equal to one another.</p> |
