Claim 4

Compact and portable signal responsive paging and voice reproduction audio notebook apparatus of a size adapted to be held in thE hand having easily selectable paging, recording and reproducing modes comprising: filter means responsive to a plurality of predetermined code groups for developing a unique audibly heard code recognition signal indicative of a remotely-generated request to enter into conversation; amplifying means effecting economy in power and space for producing said audibly heard audio output signal; hand held and manually manipulable transducer means for converting variable pressure speech characteristics into electrical current variations suitable for voice recording: voice frequency signal recording and reproducing means including recording and reproducing output terminals, and further including reversibly operable transport means having first and second input terminals; and variable switching means integrally associated with said filter means, said amplifying means, said transducer means and said voice frequency signal recording and reproducing means in a portable, single unit occupying a minimum amount of space having plural sections, said switching means operable for selectively connecting said amplifying means in common to said filter means whereby paging signals to which said filter means responds are amplified by said amplifying means, to said transducer means and said recording input terminal whereby speech tones generated by said transducer means are applied to said recording terminal of said voice signal recording and reproducing means following amplification by said amplifying means, and to said reproducing output terminal whereby signals recorded by said voice frequency signal recording and reproducing means are applied to said amplifying means for amplification in the paging, recording and reproducing modes, respectively.

Claim 5

The apparatus as set forth in claim 1 wherein said transducer means is a microphone.

Claim 6

The apparatus as set forth in claim 1 wherein a recording head is connected to said recording input terminal, and a playback head is the source of voice signals applied to said reproducing output terminal.

Claim 7

The apparatus as set forth in claim 1 wherein said amplifying means includes at least two stages of audio amplification in said paging and reproducing modes.

Claim 8

A compact and portable paging communications receiver including internally available audio notebook voice recording and reproducing facilities, said receiver being hand held in operation and comprising: filter means responsive to a plurality of predetermined code groups for developing a unique audibly reproduced code recognition signal; amplifying means effecting economy in power and space for producing said audibly heard audio output signal; hand held and manually operable transducer means for converting variable pressure speech characteristics into electrical current variations suitable for voice recording; dual purpose voice storage and retrieval means including heads for recording and playback and transport means operable in both the record and playback mode in dependence on the polarity of the transport driving voltage; variable switching means integrally associated with said filter means, said amplifying means, said transducer means, and said voice storage and retrieval means in a portable single unit occupying a minimum amount of space for selecting one of the three operating modes of paging, recording, and playback; said switching means including three banks of selector switches, each of which comprises a plurality of fixed terminals, and a movable element operable into engagement therewith under the control of a single control lever; said movable elements being operable in unison to a first position for enabling said filter means to feed said amplifying means, simultaneously disabling said transducer means, said recording and playback heads, and said transport means, to a second position enabling said transducer means to feed said recording head through said amplifying means, simultaneously enabling said transport means in a voice-recording direction and disabling said filter means and said playback head, and to a third position for enabling said playback head to feed said amplifying means, simultaneously enabling said transport means in a voice reproducing direction and disabling said transducer means, said recording head, and said filter means.
