Abstract

1,152,743. Recording and playback. MINISTER OF TECHNOLOGY. 24 Aug., 1966 [26 Aug., 1965], No. 36647/65. Heading G5R. [Also in Division H3] A sound-reproducing apparatus for playing back recorded commentaries, e.g. at exhibitions, incorporates a telephone handset 4, a magnetic tape playback device 1 arranged to apply signals to the telephone earphone and a bi-stable control circuit 5 (see Division H3), the conditions of which determine whether or not the tape is played, there being a switch in the telephone handset which sets the bi-stable circuit to initiate playback of the tape when the telephone is lifted from its rest. A sensing system 2 responds to indicia on the tape to reset the bi-stable circuit, if the telephone has been returned to the rest, at the end of the commentary. The sensing system may be operated either photo-electrically by detecting light reflected from a metal indicium or electrically by a brush contacting the metal indicium. A number of playback assemblies may be controlled by one telephone in the same way, and the tapes may be in loadable magazines.
