Abstract

1303054 Recording and playback R J FREEMAN and H FREEMAN 10 July 1970 [11 Aug 1969] 40124/69 Heading G5R A timing mechanism controls a playback system to play back recorded information at selected times. In an embodiment, a cam wheel (1, Fig. 1, not shown) is rotated by an electric clock mechanism 5, and cams (2) on the wheel trigger a normally open switch 7 to energize, via a normally closed delayed action switch 8, a tape deck motor 6, and to so cause recorded information to be replayed. The end of each recorded passage is marked by a signal, or a metal strip, and on being detected a relay 9 is activated to open switch 8 and so stop the drive motor; switch 7 also opens with switch 8, ready for the next triggering, and switch 8 finally reverts to the closed position. In a second embodiment, a latched relay (18, Fig. 4, not shown) is used.
