Time lapse recording/reproducing device that provides for both continuous recording and intermittent recording simultaneously

A recording/reproducing device for time lapse recording/reproducing a video signal comprising:

• an input/output circuit for inputting/outputting a video signal;
• a picture compression/expansion unit connected to said input/output circuit and provided with a means for intra-frame picture compressing/expanding a video signal inputted through said input/output circuit;
• a first recording/reproducing unit provided with a disk like record medium that is connected to said picture compression/expansion unit;
• a second recording/reproducing unit connected to said picture compression/expansion unit and provided with a record medium that has the capability of recording for a longer period than the record medium of said first recording/reproducing unit;
• a recording control unit to give directions and perform controlling so that a signal fed from said picture compression/expansion unit is recorded as a moving picture on the record medium of said first recording/reproducing unit and at the same time recorded intermittently on the record medium of said second recording/reproducing unit;
• and
• an alarm signal generating means for feeding an alarm signal to said recording control unit, wherein said recording control unit has the recording operation of the first recording/reproducing unit terminated after a signal fed from said picture compression/expansion unit has been recorded on the record medium of said first recording/reproducing unit from the time, when an alarm signal from said alarm signal generating means was received, till a certain predetermined time.
