Abstract

A small continuous loop tape recorder is connected to receive audio signals from a broadcast receiver, and a timer is provided to activate the recorder at intervals to record selected broadcast events. A mechanism is provided to manually activate the playback portion of the recorder whereby a previously recorded event is played back at a desired time. The receiver may be an integral part of a self-contained broadcast recorder unit, the receiver may be a conventional AM or FM broadcast receiver to which the recorder unit is connected, or there may be a combination of a self-contained receiver-recorder unit with a conventional broadcast receiver.

Claims

1. A broadcast receiver/recorder system for periodically receiving and recording selected broadcast events, comprising:

a radio receiver having an output;

a tape recorder having record and playback modes, a record input and a playback output, said tape recorder normally being in its record mode;

audio output means;

means connecting said receiver output to said record input of said tape recorder;

timer means for selectively and periodically activating said tape recorder to record selected periodic events;

first control means for selectively shifting said tape recorder from its record mode to its playback mode and for connecting said playback output to said audio output means; and

second control means responsive to said tape recorder for holding said tape recorder in its playback mode for a preselected time period and for thereafter shifting said recorder back to its record mode, whereby said recorder is activated by said timer means periodically to record each of said selected events, and is selectively activated by said first control means to play back said selected events.

2. The system of claim 1 wherein said second control means responsive to said tape recorder includes a continuous loop recording tape of preselected length, and tape controlled switch means responsive to said recording tape.

3. The system of claim 1, further including stop means for returning said tape recorder to its record mode before the end of said preselected time period.

4. The system of claim 1, further including pause switch means for interrupting the operation of said tape recorder during its playback mode without returning said recorder to its record mode.

5. The system of claim 1, wherein said means for shifting said tape recorder from its record mode to its playback mode includes playback switching means operable to activate said tape recorder.

6. The system of claim 1, wherein said means for shifting said tape recorder from its record mode to its playback mode includes:

first playback switch means operable to activate said tape recorder;

second playback switch means; and

a mode shifting switch responsive to operation of said second playback switch means to shift to a playback mode to connect said playback output to said audio output means and to shift said tape recorder to its playback mode.

7. The system of claim 6, wherein said first and second playback switch means are momentary, and wherein said second control means includes tape controlled switch means responsive to activation of said tape recorder to hold said tape recorder on for a predetermined time period and to hold said mode shifting switch in its playback mode for said predetermined time period.

8. The system of claim 7 wherein said first and second playback switch means comprise switch contact arms of a double-pole switch, and wherein said mode shifting switch comprises solenoid-controlled relay switch contacts.

9. The system of claim 1, wherein said receiver and said tape recorder comprise a unitary, self-contained, portable unit.

10. The system of claim 9, wherein said receiver and said recorder are connected in combination with a primary receiver, whereby said receiver is auxiliary to said primary receiver, the combination further including:

selected switch means connected to said audio output means for selectively connecting said primary receiver or said auxiliary receiver to said output means; and

means for disconnecting said selector switch means from said audio output means and for connecting the playback output of said tape recorder to said audio output means.

11. The system of claim 10, further including pause means for interrupting the operation of said tape recorder during its playback mode without returning said recorder to its record mode and for reconnecting said selector switch means to said audio output means.

12. The system of claim 1, wherein said second control means is further responsive to activation of said tape recorder by said timer means to maintain operation of said tape recorder in a record mode for a predetermined period of time to record a selected event of predetermined time duration.

13. The system of claim 1, wherein said second control means includes a continuous loop recording tape of preselected length, and tape controlled switch means responsive to said tape, whereby events having a time duration corresponding to the length of said tape are periodically recorded and previously recorded events are erased, whereby only the most recently recorded one of said selected periodic events is played back upon shifting of said tape recorder to its playback mode.
