In addition, the front side 8'l of the case cover 51! Since the hook 11 pawl 2a (FIG. 6) provided on the mounting board 2 side is inserted into the hook 11 hole (not shown) formed in the case cover 51b, each case cover 51 and ) The holder 4 is held in a state IE pushed into the mounting board 2 side.

"Operation of the First Embodiment" In this state, when the drive motor 58 is driven to rotate the belt pulley 56, heald 57, and rotary table 55, each engaging convex portion 55a formed on the rotary table 55 and each The hole 10 of the reinforcing member 11 attached to the center of the magnetic sheet 6 is
l[Since the magnetic sheet 6 is engaged, the magnetic sheet 6
．． 6 rotates in a synchronous manner m, and image information is magnetically recorded on the magnetic sheet 6.6 in an annular manner corresponding to the position of the magnetic helad 8.8. Immediately after recording of image information for one track is completed, the plunger 41 of the solenoid device 40 is energized to move the IE return link 37 to the left (Figure 6). This allows the partition link 35 to
5c in the clockwise direction, and the ratchet feed pawl 34 moves in the direction of arrow E along the guide pin 36. As a result, the ratchet feed pawl 34a is pulled out from the trough of the ratchet portion 27a of ratchet tooth 1 (27).

Thereafter, when the plunger 41 of the solenoid device 40 moves to the right, the 11 return link 37 also moves to the right, so the link 35 that moves 4:A rotates counterclockwise about the pivot 35c. As a result, the ratchet feed pawl 34
Since the rod moves in the direction of arrow F while being guided by the idle pin 36, the engaging portion 34a pushes the 111 portion adjacent to the valley portion of the runaet portion 27a to ratchet feed the ratchet feed 27a. Therefore, ratchet/to IM+
27 rotates clockwise around the pivot 77, so the fan-shaped tooth 1 (29) that is interlocked with this rotates counterclockwise around the shaft 32. Therefore, the fan-shaped tooth m
The pressing protrusion 31 of the pressing member 30, which rotates integrally with the ilt 29, presses the pressed surface 33a of the swinging rod 33. Therefore, the swinging rod 33 rotates in the direction of the arrow G about the pivot 54, and the magnetic head 8 attached to the swinging rod 1- also moves in the direction of the arrow H within the head protrusion window 49. young [
Moving. Therefore, the magnetic head 8 can be automatically fed so that the second recording track can be formed at a position adjacent to the first recording track magnetically recorded on the upper surface of the innermost circumference of the magnetic sheet 6. -, ratchet south +1e27
When the is ratchet-fed by the ratchet feed pawl 34 by -111 minutes, the rotating bin 24 rotates in conjunction with this in the same direction.
rotates in the direction of the arrow. Therefore, since the dial display member 15 is rotated in the same direction by the rotary bin 24, the display part 21 and the protrusion 62 display "1 20th place n rl".
can point to.

Next, when the magnetic sheet 6 is magnetically recorded to the second position from the innermost circumference by the magnetic head 8 automatically fed to form a second recording track, the ratchet gear 2
7 is solenoid device i! Since the ratchet feed pawl 34 driven by the i40 intermittently feeds one thread per thread,
The swinging rod 33 rotates in the direction of arrow G via the fan-shaped teeth i1j 29 and the pressing protrusion 31 of the pressing member 30. Therefore, the magnetic head 8 is advanced one movement to the third recording track position l.During this time, the rotating bin 24 also rotates, so the display ff
121 and the protrusion 62 are also rotated to position "2" on the scale 20.

In this way, the magnetic helad 8 is automatically fed from one to one by the action of the ratchet feed pawl 34 and the swinging rod 33 according to the number of recording tracks magnetically recorded on the magnetic sheet 6, while the display means Since the dial display member 15 of No. 13 is rotated by a number corresponding to the number of recorded recording tracks, the still image information can be easily and reliably recorded.
The number of recording tracks is 40 for the jacket holder and 72 circular holes.
It can be visually recognized with the naked eye through the hole 51a of the case force 8-51 located at a position opposite to the case force 8-51.

In this first embodiment, the number of teeth of the ratchet south +1 (27) and the number of lAy of the drive teeth 11 (25) for rotating the rotating bin 24 are set to 50, and the number of recording tracks recorded on the magnetic sheet 6L is set to 50. 50, but the number 14 can be changed arbitrarily.

Further, when, for example, 30 recording tracks (corresponding to 30 static 11: images) are recorded on the magnetic sheet 6 and the magnetic sheet 6 is taken out, the display section 2I of the dial display member 15 will be at the position "30". ” remains at 1, +r+i
You can check later how far you have recorded.

Also, when loading the magnetic sheet jacket 3 again, the dial display member 15 is at the "30" position, so
Since the human movement pin 60 in the position pointing to "0" is not inserted into the keyhole 14, the protrusion 62 of the human movement pin 60 is at "3".
0'' position. In this case, since the magnetic head F8 is configured not to perform magnetic recording during that time, redundant recording of new image information on the already recorded recording track is prevented.

Due to the position holding action of II', the state 7p is reached.

In such a state yE, when each jacket housing 115 is inserted into the jacket housing insertion/removal hole 142, the four bodies 141 that are inserted into the jacket I bodies 115 are installed in the jacket holder 129, 130. Protrusion 66
As a result, these four jacket i bodies 141 are opened from each window 7 provided in the jacket housing 115 and are therefore accommodated in the jacket housing 115. The - section of the magnetic sheet 116 that is exposed is exposed to light from the windows 130a provided in the windows 8 and 17 and the jacket holders 129 and 130.
Do t. Here, the operator pushes the outer case 125 to the original opening 71Qi. During this pushing operation, the rotational drive shaft 132 is inserted into the hole provided in the jacket holder 129, as clearly shown in FIG. 9A. 129a,
]The hole 10 of the reinforcing member 115a provided in the jacket flute body 115 on the second side is located in the center of the mounting block 128.
It passes through the through hole 128a provided in the jacket holder 130, the hole 130b provided in the jacket holter 130, and the hole 10 in the reinforcing member 115a provided in the jacket housing 115 on the door side.

37 is compressed, and the unlock button 152 engages the IL claw 123.
Once engaged, the mounting block 128, jacket holder 129, 130 will occupy a predetermined operating position (Fig. 8). : In the operating position in the JSa diagram, the magnetic head 126, 127 and the guide plate 138, 139 are
Windows 129a, 130 of jacket holder 129, 130
a reaches near the surface of the magnetic sheets 116, 116, and the distance between the magnetic head 12-6 and the guide plate 138 is the same as the post 126 protruding from the magnetic head 126 side.
The magnetic head 127 and the guide plate 139 are
Similarly to +ii, the distance between the top of the boss 127a protruding from the magnetic head 127 side is
This is ensured by contacting the step portion 139a of No.9. In this initial state, the magnetic sheets 126 and 127 occupy the positions of the innermost recording tracks of the corresponding magnetic heads 116, and the magnetic recording device 113 is operated by operating the release button 114 on the camera body 111 side. It will be in a waiting state for starting.

Operation of the first embodiment] In this state, the motor 118 is driven.

When the drive shaft 132 is rotated one rotation, the
Thus, each magnetic sheet 116 rotates +1 synchronously, and static IL image information is magnetically recorded on each magnetic sheet 116 in a ring shape corresponding to the position of the magnetic helad 126, for example. Immediately after reading 77 minutes of image information, the solenoid 143 is energized, the plunger 144 is moved f lines, and the L link 145 is rotated (Fig. 1O).
As a result, the ratchet 11 (146) is ratcheted, and on the one hand, the 11 stages of the display means 140 are advanced one track clockwise, and on the other hand, the magnetic head 126 is moved outward by one track via the swinging rod 147. This is,
The next image information is magnetically recorded in a circular manner in a second recording track adjacent to the first track, and when the release button 114 is operated for the second time, the second recording track is recorded and the first one is recorded. "1" on the display scale 140 is set to "2".

In this way, the magnetic head 126 activated for recording
is sequentially advanced by one movement according to the number of recording tracks magnetically recorded on the magnetic sheet 1-116k.Meanwhile, the display means 14
Since 114& of 0 is advanced by a number corresponding to the number of recorded recording tracks, the Okiichi image information is reliably recorded, and the number of recorded tracks can be confirmed in IPitrL.

The second embodiment has been explained in detail below, but the final principle has been revised...-'J! Since it is the same as the example, the omitted parts will be explained in 1-1 from the description of the example.
I think it is possible to imagine this in a minute.

[How to use] The following explanation of the second example and the first example is as follows.
Although the scope of the present invention is limited to the principle of how to accommodate two magnetic sheets and drive the two accommodated magnetic sheets with a drive unit configured as an RP body, the embodiment described in h is a special example. By using suitable software, that is, by selectively controlling the two magnetic heads by a combination of a control circuit including a selective recording means and a signal processing circuit, it is possible to increase the number of uses that have changed by 7:C. method can be adopted. That is: During recording (at the time of photographing) i) Detect the recording protrusion signal generated when recording is completed on one magnetic sheet 6, and proceed to recording start operation on the other magnetic sheet 6 in response to this recording completion No. Y4j] ] If configured to move dynamically, two magnetic sheets 6.6
The recording operation can be performed continuously, and therefore the recording capacity can be doubled.

1i) selectively silent 11 for the two magnetic sheets 6.6
- If a recording selection switch for recording image information is provided, it is possible to record on each magnetic sheet 6.6, for example, on the intersection II: or every 5 tracks on the intersection II:, or on one of the magnetic sheets. 6 for Mr. A, the other magnetic sheet 6
It is possible to selectively record this as Mr. B's river.

1ii) If the brightness levels are recorded in different image quality states for each magnetic sheet 6.6, one subject image can be recorded brightly on one magnetic sheet 6 and brightly on the other magnetic sheet 6, for example. You can record so that it becomes darker.

i) If one magnetic sheet 6 is configured to magnetically record still image information and the other magnetic sheet 6 is configured to magnetically record audio information, for example, , desired audio information matching the contents of the still IL image information recorded on the other magnetic sheet 6 can be recorded in order.

This earthwork 1) Continuous regeneration can be performed for two magnetic sheets 6.6.

11) If a dubbing mechanism is provided in the camera body 101 that can record still image information recorded on one magnetic sheet 6 onto the other magnetic sheet 6, The recorded still image information can be edited and recorded on the other magnetic sheets 1 and 6.

In the following, this invention will be explained through an example in which two magnetic sheets (floppy disks) are applied to an electronic still camera, but this invention is not limited thereto, and those skilled in the art will understand the spirit of this invention. Many changes and modifications may be made without departing from its scope.

For example, by increasing the number of floppy disks to two or more, you can expand the range of recordings, make the && collection even more varied, or use a compact disk (as a magnetic recording medium).
A good example of this is the use of a compact disc (CD) and a compact disk device or a magnetic recording device.

[Effects of the Invention] As explained in detail above, the present invention has a plurality of disk-shaped magnetic recording media housed in a plurality of jacket housing sections, which are rotated synchronously by a driving means, so that there is no hardware problem. For example, it eliminates the Q distortion during dubbing, significantly reduces the number of components that are safe for drive means conventionally used in devices containing multiple magnetic recording media, and reduces the failure rate associated with it.In terms of software, Recording capacity I
-) increase and variety! &! This provides the advantage of being able to selectively use each floppy disk.
