DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a still image photographing electronic camera that uses a rotating magnetic disk as a recording medium, and in particular, the rotating magnetic disk described above can be used as an audio recording/reproducing disk for recording and reproducing audio. This invention relates to an electronic camera that can be used together with the camera.

Cameras are highly portable and are widely used as a means of recording still images while traveling.

Furthermore, in addition to the image recording described above, there are many cases in which audio recording is required these days, and in that case, a tape recorder or the like must be separately prepared.

If it were possible to record both still images and audio with one device, it would be extremely convenient for reporting meetings and the like.

The present invention has been proposed in view of the above circumstances, and it adds an audio recording function in addition to a still image recording function to a still image camera using a rotating magnetic disk, which has already been proposed by the applicant. A rotating magnetic disk can be used for recording still images or audio signals, and a single electronic camera can selectively record still images or audio signals.

That is, the present invention includes an optical sensor that receives input video information, a video recording process means that converts the output of this optical sensor into a still image recording signal, a microphone that collects input audio information, and an optical sensor that converts the output of this microphone into a still image recording signal. audio recording processing means for converting into an audio recording signal; selection means for selecting an output signal from the video recording processing means or the audio recording processing means; and reproducing the recorded audio recording signal into a signal corresponding to input audio information. An audio reproduction process means, an output means for outputting the output of the audio reproduction process means to the outside of the camera housing, and a magnetic disk for recording and reproduction are all integrally provided in the camera housing, and the still image recording A signal or an audio recording signal can be selectively recorded on the magnetic disk via the selection means, and the audio signal recorded on the magnetic disk can be selectively reproduced and output outside the camera housing. That is.

The present invention also provides a means for selectively recording a still image recording signal and an audio recording signal within one camera housing, and a means for selectively reproducing an audio signal recorded on a magnetic disk and transmitting the audio signal outside the camera housing. Since all of the output means are provided, a single electronic camera can freely record still images or audio, and can also reproduce audio signals recorded on a magnetic disk.

Next, before explaining the details of the present invention, an outline of an electronic camera already proposed by the present applicant will be explained with reference to FIG.

That is, the camera housing 1 includes a lens system 2, an iris mechanism 3, a shutter mechanism consisting of a shutter plate 4 and a shutter button 5, mirrors 6, 7, and a viewfinder 8, as in a normal camera.
is provided. Further, as components unique to an electronic camera, a CCD 9 as an optical sensor for receiving input video information, a signal recording/recording 10, a motor 1 for rotating a magnetic head 11 and a magnetic disk 12 are provided.
3rd class is provided.

Further, a disk jacket 14 housing the rotating magnetic disk 12 is configured to be inserted into a jacket holder 15 of the camera housing 1 from the outside.

Then, image information from the lens system 2 is detected by the CCD 9, and sent to the magnetic head 11 as a magnetic recording signal by the signal recording circuit 10, and one image signal is concentrically recorded on each track on the magnetic disk 12. recorded. Note that the reproduced image of the above image can be viewed on a normal television.

Next, an embodiment of the electronic camera according to the present invention will be described with reference to FIGS. 2 and 3. In these drawings, the same members as those shown in FIG. 1 will be described with the same reference numbers.

That is, a lens barrel section 1A is provided protruding from the front surface of the camera housing 1, and a lens system 2 and an iris 3 are attached within this barrel section 1A. Furthermore, a pair of microphones 16, 1 are installed near both sides of the front surface of the housing 1 to enable stereo sound collection.
6 is installed. Further, a headphone terminal 17 is attached to one side of the housing 1, and a speaker 18 and an audio/video changeover switch button 19 are attached near both sides of the back side. Furthermore, inside the camera housing 1, there is a CCD 9 that detects an image captured by the lens system 2 and converts it into an electric signal, and a video recording process means 10 that converts the detection signal of the CCD 9 into an image recording signal.
A is arranged to constitute an image recording system. Furthermore, an audio recording/reproducing process means to which the microphones 16, 16 are connected, and the headphone terminal 17 and speaker 18 are connected is provided in the camera housing 1, thereby forming an audio recording/reproducing system. has been done.

The video recording processing means 10A and the audio recording/reproducing processing means are configured to selectively send a video signal or an audio signal to the magnetic head system 11A by operating a changeover switch 21 using a changeover switch button 19. Note that the magnetic head system 11A is configured in a two-head system.

Further, the motor 13 is equipped with a chuck mechanism at the end of its output shaft 13A, and has a magnetic disk 12 which will be described later.
It is designed to be driven in rotation.

A motor controller 22 for changing the rotation speed of the motor 13 and a head shift controller 23 for changing the tracking state of the magnetic head 11A so that it becomes concentric or spiral are connected to the audio/video changeover switch button 19. has been done.

Further, reference numeral 14 denotes a disk jacket, and a circular sheet-shaped magnetic disk 12 is housed inside.By loading the jacket into a jacket holder 15 provided on the back of the camera housing 1, the motor output shaft 13A is aligned at the center of the disk. When inserted into the hole 12A, the magnetic head system 11A comes into sliding contact with the magnetic recording surface of the magnetic disk 12.

In the above configuration, when photographing a still image, when the changeover switch button 19 is switched to video mode, the motor controller 22 changes the rotational speed of the motor 13 to, for example, 1/60 sec.
The magnetic head system 11A is shifted by the head shift controller 23 so as to concentrically track the magnetic disk 12, and the changeover switch 21 is switched to the terminal 21A side, and the video recording process means 10 is switched to the terminal 21A side.
A is connected to the magnetic head system 11A. In this state, when the shutter button 24 is turned on, the magnetic disk 12 contains one still image signal.
The track state can be recorded and photographed as a concentric track T as shown in FIG. 4A.

On the other hand, when recording audio using the camera configured as described above, when the audio/video switching button 19 is switched to audio mode, the switching switch 2
1 is switched to the terminal 21B side, that is, the audio recording/reproducing process means 20 side, the microphones 16, 16 are connected to the magnetic head system 11A, the speaker 18 or the headphone terminal 17 is connected, and the motor controller 22 is connected to the motor 13. At the same time, the head shifter 23 switches the rotation speed of the magnetic head system 1 so that the rotation speed of the magnetic disk 12 is 8 seconds/rotation.
1A is switched so that it comes into sliding contact with the disk surface in a spiral manner.

As a result, when a recording button (not shown) is turned on, the sounds collected from the microphones 16, 16 are recorded on the magnetic disk 12 as a spiral recording track T as shown in FIG. 4B.

To reproduce the audio from the magnetic disk 12, a speaker 18 provided on the camera or a headphone 28 connected to the headphone terminal 17 is used.
Alternatively, as shown in FIG. 5, you can take out the magnetic disk jacket 14 recorded by the camera C and use the video player 25 as an adapter to listen to it through the speakers of the television receiver 26. You can do it like this.

Furthermore, it is convenient to provide camera C with a switch for switching between monaural recording and stereo recording. Furthermore, as shown in FIG. 2, if a battery pack 27 is prepared and connected to the camera C, it will be convenient for long plays.

As described above, in the present invention, a magnetic disk for video can be used for recording and reproducing audio signals, and a single disk can be used to record video and record and reproduce audio.

Furthermore, by using a magnetic disk recorded in a studio, high-quality stereo monitoring becomes possible, and the camera used while traveling can be transformed into a portable recording/playback device.
