It is possible. The damper 32 engages the helad load arm 12 and causes the second carriage 4 with at least one head to rest on the medium contained in the disk cartridge 17.

For attachment, a root 33 is provided on the frame 1, and a plurality of threaded portions are provided for attachment to the device.

The operation of the structure of the present invention having the above structure will be explained. First, to install the disk cartridge 17, in the standby state at the disk cartridge insertion/extraction position shown in FIG.
When inserted in the 8 direction, the decorative plate lid 16 is opened and comes into contact with the shutter opening/closing arm 9a of the shutter lever 9, and the shutter 17a is opened in the arrow 28 direction. When the disk cartridge 17 is further advanced, it comes into contact with the trigger arm 11b of the trigger 11, causing the trigger 11 to rotate in the direction of the arrow 26. When the disk cartridge 17 is further inserted, it comes into contact with the holder stopper part 6f of the holder 6, and
It moves together with the holder 6 in the direction of arrow 18 against the biasing force of the biasing member 8 .

Then, the guide roller 60 of the holder 6 comes off from the horizontal guide groove 1b of the frame 1, and the holder 6 moves in the direction of arrow 23 due to the urging force of the urging member 8, as shown in FIGS. 3 and 5. It is attached to the recording/playback position. At this time, the holder 6 is prevented from moving in the direction of the arrow 19 by the vertical guide groove IC of the frame 1. Further, the trigger rotation locking portion 11c of the trigger 11 engages with the frame locking portion 1e of the frame 1, so that the trigger 11 is prevented from rotating in the direction of the arrow 27. As a result, the biasing force in the direction of the arrow 19 is no longer exerted on the disk cartridge 17. - The rotating body 7 is in contact with a part of the holding body arm 6b of the holding body 6 and the rotating body stopping portion 7d with play in the standby state of the disk cartridge insertion/extraction position shown in FIG. rotation is stopped. Furthermore, the eject button 14 and the button lever 15 are in a retracted state by the rotating pressing part 7b of the rotating body 7, but when the above-mentioned mounting operation is performed, the holding body arm 6b of the holding body 6 is pressed against the rotating body 7. The rotating body 7 is rotated in the direction of arrow 20 by contacting the rotating body arm 7C. At this time, eject button 14
The button lever 15 is slid in the direction of the arrow 19 by the rotating body pressing portion 7b of the rotating body 7, and enters the state shown in FIG. As a result, the medium stored inside the disk cartridge 17 inserted into the holder 6 comes into contact with the head of the carriage 3 and at least one head of the second carriage 4, as shown in FIGS. 2 and 3. Recording and reproduction are performed by sliding in the directions of arrows 18 and 19 by the drive means of the drive motor 2.

Next, ejection of the disk cartridge 17 will be explained. In FIGS. 3 and 5, when the eject button 14 arranged in parallel on the decorative board 5 is pressed in the direction of the arrow 18, the button lever 15 to which the eject button 14 is attached presses the rotating body pressing portion 7b of the rotating body 7. Then, the rotating body 7 is rotated in the direction of arrow 21 around the rotating protrusion 7a of the rotating body 7.

Then, the rotor arm 7c engages with the holder arm 6b and lifts the holder 6 at the rear as shown in FIG. At this time, the guide roller 6e of the holder 6 engages with the vertical guide groove 1C of the frame 1 and is prevented from moving in the direction of the arrow 19. When the eject button 14 is further pressed, the holding body 6
It comes into contact with the removal prevention screw 31 and becomes the center of rotation, lifts the front of the holder 6 in the direction of the arrow 34, and the guide roller 6
e is removed from the vertical guide groove IC, the holder 6 slides in the horizontal guide groove 1b in the direction of arrow 19 by the biasing member 8, and is locked by the locking groove 1a of the frame 1.

On the other hand, the trigger rotation locking portion 11c of the trigger 11 engages with the frame locking portion 1e of the frame 1, preventing rotation in the direction of arrow 27, but the holder 6 prevents sliding in the direction of arrow 19. Once started, the trigger 11 is rotated in the direction of arrow 27 by the shutter lever spring 10, and the trigger arm 11b contacts the disk cartridge 17 to eject it in the direction of arrow 19. The shutter lever 9 also returns in the direction of arrow 25. Further, the rotor stopping portion 7d of the rotor 7 engages with the holder arm portion 6b again, and the disk cartridge is returned to the disk cartridge insertion/extraction position shown in FIG. Also, in the above explanation,
When lifting the holding body 6, first lift the rear part, then
I explained that the front part is lifted up, but the position of the holder spring 8 attached to the holder 6 is indicated by the arrow 19.18.
By moving the holding body arm 6b and the rotating body arm 7c, you can lift the holding body 6 with the front first, the rear first, or almost parallel. It is also possible to lift it up. This is because the holding body 6 is lifted at two points on both sides by the rotating arm 7c of the rotating body 7.

Next, locking of the holding body 6 when it is not in use will be explained.

The unnecessary operation of the holder 6 is when the disc cartridge 17 is inserted incorrectly, the holder 6 slides before the shutter 17a of the disc cartridge 17 is opened, or the shutter 17a does not open. In FIG. 8, when the disk cartridge 17 is inserted in the direction of arrow 18 with the front and back or front and back reversed, the shutter lever 9 rotates in the direction of arrow 24 and the shutter opening/closing arm 9
However, when it is further inserted, the shutter lever lock portion 9b comes into contact with a part of the holder 6 before it comes into contact with the trigger arm 11b of the trigger 11. Then, the holder 6 slides a little in the direction of the arrow 18 against the biasing force of the biasing member 8, but eventually the trigger holder lock portion 11a of the trigger 11 disposed on the holder 6 and the frame 1 It comes into contact with the provided frame lock portion 1e and is prevented from sliding in the direction of arrow 18, as shown in FIG. As a result, the holding body 6
Since it does not come off the horizontal guide groove 1b shown in the figure, it is not attached to the recording/reproducing position. Further, even if the shutter lever 9 does not swing and the holder 6 slides in the direction of the arrow 18 due to some external force, the holder 6 will not be attached due to the above-described operation. This prevents damage to internal components of the device. As described above, in the present invention, when the holder 6 is moved from the recording/reproducing position to the disk cartridge insertion/extraction position and returned, the structure is explained in which the rear part of the holder 6 is lifted by the rotating body 7 and then the front part is lifted. It is also possible to create a structure in which the front of the holding body 6 is lifted first and then the rear thereof is lifted by changing the position of the biasing member 8 and the position of the rotating body arm 7C. It is also possible to lift it horizontally.

[Effects of the Invention] As described above, according to the present invention, when a disk cartridge is inserted into the holder at the insertion/extraction position, the holder slides into the groove provided in the frame, and the biasing member causes the recording to be performed. attached to the playback position. Since the holding body is returned to the insertion/extraction position again by rotating the rotating body that is in contact with the holding body, the sliding load is reduced by the rotation. Furthermore, there is no need for a separate guide for the rotating body, and space can be reduced by arranging the rotating body on the upper surface of the holder, that is, on the disk cartridge insertion/extraction side. Further, since the holding body is held by a groove provided in the frame, the number of parts to be guided can be reduced, thereby eliminating wasted space, and the size of the parts can also be reduced. As a result, a thin magnetic recording device can be provided, and the practical effects of the present invention are great.
