Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic recording device, and more particularly to a magnetic recording device that records still images on a disc-shaped magnetic recording medium.

It is generally known that still images can be recorded and reproduced by using a video camera and a video tape recorder used for recording moving images. However, since this type of device uses a thin magnetic tape as a recording medium, when playing back still images, the magnetic head continuously scans the same location on the magnetic tape, causing damage to the magnetic tape. It is extremely unsuitable for recording and reproducing still images.

In response to this, in recent years so-called electronic cameras have been proposed and developed that record still images on disk-shaped magnetic recording media (hereinafter referred to as magnetic disks). An electronic camera generally uses a solid-state imaging device such as a CCD, photoelectrically converts a subject image, extracts an image signal, and records one still image per rotation of a magnetic disk that rotates at a predetermined speed. These electronic cameras use magnetic disks, which are relatively thicker than magnetic tapes, so they are suitable for recording and playing back still images, but unlike magnetic tapes, they cannot be wound onto reels to provide a large storage capacity. Therefore, there is a problem that the recording capacity of a single magnetic disk is extremely small compared to that of a magnetic tape.

Conventionally, as a means to solve this problem, it has been proposed to stack magnetic disks in several layers and use these magnetic disks selectively. It is necessary to rotate the disks at the same time, and moving the magnetic head becomes complicated, resulting in an increase in the size of the device.
There is also the disadvantage of increased costs. Furthermore, if continuous shooting is not required, it is sufficient to replace the magnetic disk, and when used for such purposes, a compact and lightweight device is desired even if the recording capacity per disk is small.

The present invention has been made based on the above-mentioned circumstances, and it is an object of the present invention to provide a magnetic recording device that can continuously record a large number of still images and is small and lightweight during normal use.

In order to achieve the above object, the present invention provides a first apparatus for photoelectrically converting a subject image and recording the image signal on a magnetic disk.
A second device including a first storage unit that stores a plurality of magnetic disks for recording and a second storage unit that stores a recorded magnetic disk. The present invention is characterized in that a second sending means for sending the recording magnetic disk to the first device is provided, and the first and second devices are coupled as necessary.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

Further, the gear portion 8a of the holder 8 meshes with a drive gear 20 of the holder moving motor 19, and the position of the holder 8 is regulated by the moving motor 19. That is, in the position shown in FIG. 1, the magnetic disk 7 and the drive motor 4 are in a mounted state, and in the position shown in FIG. 3, they are not mounted. Incidentally, an insertion hole 21 and a discharge hole 22 for the jacket 6 are provided on the side surface of the first device 1.
A release button 23, a photographing mode selection switch 24, etc. are provided on the top surface.

FIG. 3 is a diagram showing a state in which a second device is coupled to the first device. As shown in the figure, the second device 25 includes a first accommodating section 27 that accommodates a plurality of recording jackets 26, and a second accommodating section 27 that accommodates the recorded jackets 28 sent out from the first device 1.
A housing portion 29 is formed to sandwich the first device 1 therebetween. The first housing section 27 of the second device 25 is provided with rotating rollers 30 to 32 and a feed-out roller 34, and the feed-out roller 34 has an endless belt 36 that transmits the rotation of the second feed-out motor 35. It is suspended horizontally.

Next, the operation of this embodiment configured as described above will be explained.

For example, when performing continuous shooting, the second device 25 is coupled to the first device 1 as shown in FIG. 3, and the shooting mode selection switch 24 is set to the continuous shooting mode. When the release button 23 is pressed, the magnetic disk 7 of the jacket 6 held in the holder 8
is rotationally driven by a drive motor 4, and this rotation causes the magnetic head 5 to slide on the magnetic disk 7 in the circumferential direction. On the other hand, the subject image from the imaging lens 2 is converted into an electrical signal by the solid-state imaging device 3, processed by a known circuit configuration, and then magnetized and recorded on the magnetic disk 7 via the magnetic head 5. Ru. Here, one frame of a still image recorded on the magnetic disk 7 is recorded on one track, and the magnetic head 5, which has finished recording one frame, is moved toward the center of the magnetic disk 7 by known means. In the case of continuous shooting mode, the above recording operation is repeated at regular intervals.

In this way, when the magnetic head 5 moves close to the center of the magnetic disk 7 and a predetermined number of still images are recorded on the magnetic disk 7, the position of the magnetic head 5 is detected by known means such as a limit switch. be done. As a result, the magnetic head 5
returns to the initial position, and the holder moving motor 19 is driven to move the holder 8 to the position shown in FIG. When the movement of the holder 8 is completed, the first feed motor 15 is driven,
The rollers 13 and 14 of the holder 8 are rotated counterclockwise in FIG. 3 via the endless belt 16. As a result, the jacket 6 on which the still image is recorded
is sent out from the discharge hole 22 by the rotation of the rollers 13 and 14, and is accommodated in the second storage section 29 of the second device 25.

On the other hand, when the jacket 6 is fed out from the discharge hole 22, the second feed motor 36 is driven, and the rotation of the roller 31 causes the jacket 26 accommodated in the first accommodation portion 27 to be delivered from the insertion opening 21 to the holder 8.
is sent to the entrance of At this time, the first feed motor 15 is driven again to hold the jacket 26 in a predetermined position within the holder 8. When the jacket 26 is held at a predetermined position within the holder 8, the holder moving motor 19 is driven in the opposite direction to the above, returning the holder 8 to its original position as shown in FIG. The action is performed again. Furthermore, the first
The second feed motors 15, 36 and the holder moving motor 19 are controlled by known means and rotate as many times as necessary.

Furthermore, when using the camera in the normal shooting mode (single-shot shooting), it is also possible to use only the first device 1.
