Abstract

1485672 Audio-visual apparatus KONISHIROKU PHOTO INDUSTRY CO Ltd 29 Oct 1975 44766/75 Heading G5R A transparency 1 carrying a magnetic recording area 3 is located by means of holes 14 engaging pins 13 on an illuminated face 5 and is recorded or played back by means of a magnetic head 11 moving either rectilinearly as shown or spirally, Figs. 5 and 6 (not shown). The recording area 3 may be pressed against the magnetic head 11 by a pressure plate 28, Fig. 4, hinged to the head mounting 1 la. As described, in the rectilinear layout the head 11 is driven to and fro by an electric motor (15), Fig. 3 (not shown), through a lead-screw 16 under the control of limit switches (18, 19) which also cause a switch (20) to effect change of track in a multi-track head 11 and to switch off at the end of the last track, or earlier in response to a recorded signal.
