Abstract

Abstract An integral recording unit type television camera which is provided with a trigger signal generating unit which generates an external trigger signal and internal trigger signal for controlling to a recording state or stopping state an external recording unit (2) and internal recording unit (1) by operation of a start/stop switch and which controls the trigger signal generating unit (5) so as to output both the external trigger signal and the internal trigger signal when both an external recording unit and internal recording unit are in the recording state or stopping state and so as to output just the internal trigger signal when the external recording unit is in the recording state and the internal recording unit is in the stopping state and, further, a tape cassette of the internal recording unit is in a recording standby state, whereby it is possible to place both the internal recording unit and external recording unit simultaneously in the recording state or the stopping state by operation of a single start/stop switch and whereby when the recording state of the internal recording unit is released due to the tape running out or other reasons, it is possible to place the internal recording unit in the recording state again without release of the recording state of the external recording unit by mounting a new tape cassette and operating the start/stop switch, thus enabling simultaneous control of the recording of the external recording unit and internal recording unit at the television camera side and, further, simplifying the operation due to operation by a single start/stop switch. Also, an integral recording unit type television camera which can be connected to an external recording unit by a cable, wherein provision is made of an AND circuit (A2,A3) and an OR circuit (A1) for obtaining the AND condition and OR condition of an internal status signal showing the operating state of the internal recording unit and an external status signal showing the operating state of the external recording unit, respectively, and wherein the output of the AND circuit is supplied to a display means when both the recording units are in the recording state and the output of the OR circuit is supplied to the display means when one is in the recording state, so the operating states of the two recording units are displayed by the display means by the AND signal of the internal status signal and the external status signal when both the recording units are in the recording state, an abnormality is displayed by the display means if one or both of the recording units show an abnormality, and the operating state of a single recording unit is displayed by the display means by the internal status signal or the external status signal when that recording unit is in the recording state, whereby there is the effect that it is possible to recognize the operating states of not only the internal recording unit but also the external recording unit by the display means.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 246 words
An integral recording unit type, television camera comprising: an internal recording unit (1) which stores video signals supplied from a picture element; a means for supplying said video signal through a cable to an external recording unit (2): an external recording state detection means for detecting which of a recording state and a stopping state said external recording unit is in; an internal recording state detection means (3) for detecting which of a recording state and a stopping state said internal recording unit is in; a cassette status detection means (S1,S2) for detecting if a tape cassette in said internal recording unit is in a state standing by for recording; a trigger signal generating means (5) for generating an external trigger signal and an internal trigger signal for controlling the recording state and stopping state, respectively of said external recording unit and said internal recording unit by operation of a start/stop switch; and a control means (6) for controlling said trigger signal generating means so as to output both said external trigger signal and said internal trigger signal when both said external recording state detection means and said internal recording state detection means detect one of said recording state and stopping state and so as to output just said internal trigger signal when said internal recording state detection means detects the recording state and said internal recording state detection means detects the stopping state and, further, said cassette state detection means detects a recording standby state.
Claim 2
Dependent Claim 148 words
An integral recording unit type television camera comprising: an internal recording unit for recording a video signal supplied from a picture element; a means for supplying the video signal through a cable to an external recording unit; an AND circuit for obtaining the AND condition of an internal status signal showing the operating state of the internal recording unit and an external status signal showing the operating state of the external recording unit; an OR circuit for obtaining the OR condition of the internal status signal and the external status signal; and a control means which supplies a display means with the output of the AND circuit when both the internal recording unit and the external recording unit are in the recording state and the output of the OR circuit when only one of the internal recording unit and the external recording unit are in the recording state.
Claim 3
Independent Claim 140 words
An apparatus having as a single unit a video camera and a first video recorder for recording and or reproducing a video signal generated by said video camera comprising: an output terminal for supplying said video signal to a second video recorder provided outside of said signal unit, first means for detecting a recording operation of said first and second video recorders, second means for detecting an existence of a record medium in said first video recorder and a condition whether the same being ready for recording, means for generating an outer and an inner trigger signals in response to a command signal generated by an operation of a command key and output signals of said first and second detecting means so as to activate at least one of said first and second video recorders to start recording operation thereby.
Claim 4
Dependent Claim 90 words
The apparatus according to claim 1, in which both of said outer and inner trigger signals are generated when said first detecting means detects the same condition of said first and second video recorders, and only said inner trigger signal is generated when said first detecting means detects a recording mode of said second video recorder and stop mode of said first video recorder and simultaneously when said second detecting means detects the existence of said record medium in said first video recorder and the same is ready for recording.
Claim 5
Dependent Claim 113 words
The apparatus according to claim 2, said apparatus further comprising and indicator for indicating disable condition of recording of at least one of said first and second recorders, and means for supplying disjunction signal of an inner condition signal representing an operating condition of said first video recorder and an outer condition signal representing the same of said second video recorder to said indicator when said first detecting means detects said first and second video recorders being activated for recording, and for supplying conjunction signal of said inner and outer condition signals to said indicator when said first detecting means detects one of said first and second video recorders being activated for recording.
