Abstract

872,424. Magnetic sound-and-picture sheets; copying. TOKYO DENKI KAGAKU KOGYO KABUSHIKI KAISHA, and HOSHINO, J. Nov. 19, 1958 [Nov. 20, 1957 (2)], No. 37254/58. Class 40 (2). A multiple machine, of the type described in Specification 850,291 has common drive means for all the turntables T and two multiple pressure plates 22, one being available for reloading as the other is holding record sheets in transducing position. The apparatus shown may be used either to produce three simultaneous records from an external signal source, or by suitable switching may record two copies of a record simultaneously played back at a third turntable.
