DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A recording / reproducing apparatus with a photographing device (hereinafter abbreviated as a disk camera) according to an embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram of the disk camera of this embodiment. FIG. 2 is a perspective plan view of this embodiment.

In FIGS. 1 and 2, the optical image from the taking lens 1 is a photoelectric conversion element (CCD) 2 and a video circuit 3.
Is converted into a video signal. The video signal is converted into a predetermined recording signal by the recording / reproducing circuit 4, and is recorded on the disk 7 via the optical head 6 while detecting the recorded data capacity by the capacity detecting circuit 5. The disk 7 is a control circuit 9 that controls the drive of the spindle motor 8.
Is rotating at a predetermined rotation speed. Also, the optical head 6
Is a guide shaft 10 for transporting the optical head 6,
Screw guide shaft 11 and stepping motor 1
A traverse mechanism 13 for coarse movement composed of 2 and an actuator (not shown) for finely moving the optical head 6 are controlled so as to follow a track on the disk 7.

For reproduction, the spindle motor 8 is rotated by the high-speed reproduction control circuit 9b of the control circuit 9 to rotate the disk 7 at high speed, and the signal recorded on the disk 7 is read out at high speed by the optical head 6. The read signal is accumulated in the memory 4a of the recording / reproducing circuit 4 while detecting the data amount of the reproduced signal by the capacity detecting circuit 5, converted from the memory 4a to a normal reproducing speed, and reproduced from the reproducing output terminal 13 to the outside. Output as.

Next, the case where the disc 7 is replaced at the time of recording will be described. When the capacity detection circuit 5 detects that the recording capacity of the disk is exhausted while recording a captured image, the control circuit 9 interrupts the recording operation on the disk 7 and the memory in the recording / reproducing circuit 4 is stopped. Recording signals are accumulated in 4a.

While the signal is being stored in the memory 4a, the rotation of the disk 7 is stopped, the disk 7 is separated from the spindle motor 8, and the disk transfer lever 14 is rotated by the control circuit 9 in the direction of arrow A. And disk 7
Is transferred from the recording / reproducing position to the storage rack 15 and stored.

As shown in FIG. 2, a plurality of disks 7a to 7g are inserted into the storage rack 15, and the storage rack 15 is provided with the disks 7 which have been used for recording up to now. Rack 16a and rack transfer guide 16
The storage rack moving mechanism composed of b and the rack moving motor 17 moves the storage rack 15 in the B direction to move the disk transfer lever 14 in order to transfer a new disk (for example, 7d) from the storage rack 15 to the recording / reproducing position. The disc 7d is rotated in the direction opposite to the arrow A, and the new disc 7d is set at the recording / reproducing position. When the disk 7d is mounted, the spindle motor 8 is driven and controlled by the high-speed recording control circuit 9a in the control circuit 9 to rotate the disk 7d at high speed, and the signal stored in the memory 4a is transferred to the disk through the optical head 6. High speed recording is performed on 7d. Then, when there is no data accumulated in the memory 4a, the rotation speed of the spindle motor is slowed down to return to the normal recording operation.

Next, the disc exchange at the time of reproduction will be described. When a signal is being reproduced from the disc, the high-speed reproduction control circuit 9b drives and controls the rotation of the disc and the optical head so that the signal corresponding to the disc exchange time is always stored in the memory 4a in advance so that the signal is reproduced at high speed. To do. When the capacity detection circuit 5 detects that the reproduction signal on the disk 7 has disappeared, the control circuit 9 replaces the disk in the same manner as in the case of the replacement at the time of disk recording. During the disk exchange, the data stored in the memory 4a is output from the reproduction output terminal 13 as a reproduction signal.

The disc can be exchanged manually by the exchange switch 19 provided on the handgrip 18 in the same manner as described above.

The above-described embodiment has been described with respect to the case of the disk medium, but it goes without saying that the same principle can be used for recording and reproducing in the case of the tape medium.

Further, the storage rack portion of the disk may be constructed so as to be separable from the main body of the image taking apparatus so that the storage rack can be exchanged. Furthermore, the photographing unit and the recording / reproducing unit may be separated.

As a recording method, the recording operation to the memory is performed when the recording capacity of the recording medium is exhausted. However, recording is always performed on the recording medium through the memory and the recording medium is exhausted when the recording capacity is exhausted. It is also possible to interrupt the recording operation to.

Further, the method of using the memory is not limited to the method of this embodiment as long as it can be controlled so that the recorded and reproduced images are not interrupted during the recording or reproducing operation.

[0026]

As described above, according to the present invention, a plurality of recording media (disks, tapes, etc.) are accommodated in the main body, the media are automatically replaced, and the recorded image or reproduction during the replacement is performed. Images can be recorded and played back without interruption. Furthermore, by automatically exchanging the medium, the exchanging time is shortened, and a plurality of accommodating media can be stored. Therefore, it is not necessary to carry the recording medium separately, and a recording / reproducing apparatus with a photographing device having good operability can be realized.
