The operation of the recording apparatus having the above structure will be described with reference to FIG.

First, the camera 31 and the microphone 32
By supplying electric power to the recording apparatus and turning on the power switch of the recording apparatus, the signal storage unit 1 and the recording control unit 3 are brought into the operation start state S.

At this time, the camera 31 and the microphone 32
The image pickup signal and the audio signal supplied from the A / D converter 6 and the A / D converter 8 of the signal storage unit 1 are A / D converted, and the system control unit 23 of the recording control unit 3 issues an A / D conversion command to start A / D conversion. The D / D-converted image pickup signal and audio signal are supplied to the image signal processing unit 7 and the audio signal processing unit 9 and converted into an image signal and an audio signal by the above signal processing, and the image signal and the audio signal are time code generated. The track formatting processing unit 12 performs the permutation processing together with the time signal generated by the device 11. Next, in response to an instruction from the system controller 23 to start signal processing from the writing controller 21, the permutation-processed image signal and audio signal become the writing state MW in the signal memory 13.

Next, when a recording start operation is performed by the operation unit 4, the operation of the servo control system is started, and a control signal is supplied from the operation unit 4 to the system control unit 23. From this system control unit 23 to the read control unit 21
The reading instruction is given to. By the control of the read control unit 21 receiving this instruction, the image signal and the audio signal stored in the signal memory 13 before the time T are output after the time L from the start of the operation of the servo control system to the lock. The read state MR is read from the port.

The image signal and the audio signal stored before the time T are controlled by the read control unit 22 according to the instruction of the system control unit 23, and the signal memory 1 of the signal storage means 1 is controlled.
3 is supplied to the recording means 2 and the recording means 2 starts recording on the video tape 35 in accordance with an instruction from the system control section 23. Therefore, the image signal and the image signal before the recording start operation is performed by the operation unit 4 are recorded.

After that, when a recording end operation is performed on the operation unit 4, the read state M after a time T from the end operation.
R ends. Therefore, the image signal and the image signal after the recording end operation is performed by the operation unit 4 are recorded.

The writing state MW is ended by turning off the power switch of the recording apparatus.

In the above recording apparatus, when the time T is set to be longer than the time L in advance, the power is supplied from the camera 31 and the microphone 32 before the recording start operation is performed by the operation unit 2. The image pickup signal and the audio signal are recorded on the video tape 35 by the recording means 2.

Therefore, the image signal and the audio signal before the recording start operation is recorded by the operation unit, and the decisive moment can be surely recorded without missing the photo opportunity.

In the above embodiment, the case where the video tape is used as the recording medium for recording by the recording means has been described, but the present invention is not limited to such recording means, and for example, a magneto-optical device other than the video tape is used. The present invention is also applicable to the case where a recording means such as a disk is used as a recording medium for recording.

[0024]

As described in detail above, according to the recording apparatus of the present invention, when power is supplied from the power source,
Writing the supplied image signal and audio signal into the signal memory of the signal storage means, and recording means for recording the image signal and audio signal stored in the recording memory when a recording start operation is performed by the operation unit. It is possible to record on a recording medium.

Therefore, the image signal and the audio signal before the time when the recording operation is started by the operation unit are recorded, and the decisive moment can be surely recorded without missing the photo opportunity.
