Abstract: 1,065,165. Recording and playback. H.LEITNER. Dec.18, 1964 [Jan. 23, 1964], No. No. 51617/64. Heading G5R. [Also in Division H4] .  A telephone subscriber s equipment. cornprises a telephone receiver, a loud-speaker, a dial, and a repertory dialler all included in or on a single housing which contains a storage medium, e.g. a magnetic band, on which dialling pulse sequences and incoming calls may be recorded in separate transversely spaced tracks. Fig. 2 shows the storage medium, i.e. magnetic band 17 and the apparatus for indexing the  record playback head 16 to various positions for recording or replay of different dialling pulse sequences. The head 16 is indexed to a particular track by operation of one of the pushbuttons 8. Depression of a push-button is arranged to release a catch 13 to allow plate 15 which is mounted on band 18 and which carries the record replay head 16, to be moved transversely across the record medium 17 by the spring 20 until-the edge of plate 15 engages the depressed button 8. Motor 27 is then energized to drive the record medium 17 past the head to record or reproduce the track selected by the respective button. In order to restore the head 16 to its original position when the record or replay operation is completed a traction magnet 28 is energized which disengages the drive to the record medium and engages a drive to roller 23 to rewind band 18 against the tension of spring 20. When the head 16 is in its original position the catch 13 re-engages ready for another button to be depressed. The motor and traction magnet may be energized in accordance with signals recorded on a control track on band 17 reproduced by head 31. The apparatus may be used as a telephone answering machine in which case the subscriber records a message on the record-medium using head 32, to be subsequently replayed automatically by .this head. Fig. 4 shows the electrical circuit of the subscriber's equipment in which switches 56 and 60, normally ganged provide, in a first position for the use of the machine as a standard telephone, in a second position the 'received signals are amplified in amplifier 57 and applied to loudspeaker 58, in a third position a microphone 61 is connected to record an answering signal on the record medium via head 32, in a fourth position the head 32 is connected to replay the recorded message to the line via amplifier 57, while in the final position the arrangement is connected as a repertory dialler  in which, with the relay contacts 48I to 48VII in the positions showns, impulses picked up from a recorded track on the head 16 operate, via a monostable trigger 59, a polarized relay 47 which has impulsing contacts 47I connected in the line circuit, while with contacts 48I to 48VII in their other condition impulses produced by the dial impulsing contacts 49 operate the monostable circuit 59 to record impulses on the record medium via head 16. A call relay 65 is provided to initiate the answering sequence in the absence of the subscriber and this relay may also operate a tape recorder to record incoming calls, or to cause the recording of the incoming calls on tracks of the record medium between the dialling impulse tracks.
