On the other hand, a connecting piece 32d bent at the front portion of the cam plate 32 is inserted into the groove 38b on the other end side of the conversion lever 38. As a result, the conversion lever 38 functions to convert the movement of the slide plate 37 in the directions of arrows A and B into the rotation of arrows E and F, and also to perform the reverse conversion.

Next, the operation of the above configuration will be described with reference to FIG. 3 and FIG.

(1) Loading of Cartridge In a standby state before loading of the cartridge, the engaging piece 34a of the cartridge hook 34 is inserted into the engaging hole 33a on the side surface of the receiver 33, and the cartridge hook 34 is stationary against the spring 52. . The eject lever 35 has a contact piece 35
a is suspended, and the contact piece 35a contacts a notch 31e formed at the rear of the frame 31, whereby the eject lever 35 is also stopped against the spring 46.

On the other hand, a locking piece 32e is formed at the left rear end of the cam plate 32, and the locking piece 32e is locked to the hook piece 36a of the cam plate hook 36, whereby the cam plate 32 is Resist
The movement in the directions of arrows A and B has stopped. Note that this locking piece 3
2e is inserted into a hole 31f formed in the frame 31.

In such a standby state, when the cartridge 4 is inserted in the direction of arrow A into the receiver 33, the arc-shaped corner 4c of the cartridge 4 is engaged with the engagement piece 34 of the cartridge hook 34.
In order to press the cartridge a, the cartridge hook 34 rotates in the direction of arrow E against the spring 52, whereby the engaging piece 34a comes into contact with the side surface 4d of the cartridge 4. When the cartridge 4 is further pushed in the direction of arrow A, the rear end face 4e of the cartridge 4 comes into contact with the pressing piece 35b at one end of the eject lever 35, so that the eject lever 35 rotates in the direction of arrow F against the spring 46.

Subsequently, when the cartridge 4 is pushed in, the engagement piece 34a of the cartridge hook 34 is
f, and the contact piece 35a of the eject lever 35 contacts one of the hook pieces 36b of the cam plate hook 36.
The cam plate hook 36 starts rotating in the direction of arrow F against the spring 48. As a result, the hook piece 36a of the cam plate hook 36 is disengaged from the engagement with the locking piece 32e of the cam plate 32.
2 is moved in the direction of arrow A by the bias of the spring 47, and the automatic retraction of the cartridge 4 is started.

FIG. 4 (a) shows a state before the automatic retraction, and when the automatic retraction of the cartridge 4 is started by the above-described operation, the cam groove 32a of the cam plate 32 moves in the direction of arrow A as shown in FIG. 4 (b). The cam groove 32a and the guide groove 3 of the frame 31
The receiver pin 45 inserted in 1a also moves in the direction of arrow A. Therefore, a receiver with receiver pin 45 attached
33 also moves in the same direction as the cam plate 32 moves in the direction of arrow A. As the receiver 33 moves in the direction of arrow A, the engaging piece 34a of the cartridge hook 34 comes into contact with the end face 4g of the engaging hole 4f of the cartridge 4 to transmit the moving force of the cartridge 4. And automatically moves in the direction of arrow A. That is, the cartridge 4 is pushed by hand until the lock of the cam plate hook 36 with the cam plate 32 is released.
Is automatically retracted.

When the cartridge 4 is pulled in the direction of the arrow A, the eject lever against which the rear end face 4e of the cartridge 4 is in contact
Since the pressing piece 35b of 35 is pushed in the direction of arrow A, the eject lever 35 is forcibly rotated in the direction of arrow F against the eject spring 46 about the shaft 39. At this time, the force for moving the eject spring 46 in the direction of the accumulated force is the spring 47 on the cam plate 32 side.
Is served by Therefore, the spring 47 of the cam plate 32 needs to have a sufficient spring force to rotate the eject lever 35 in the direction of arrow F against the bias of the eject spring 46.

Next, when the receiver pin 45 passes the position shown in FIG. 4B, the receiver pin 45 enters the guide groove 31b of the frame 31, so that the receiver 33 and the cartridge 4 move in the arrow C direction. Then, the cartridge 4 is moved to the positioning holes 4a, 4
The position is corrected by b and the cartridge guide 41,
Since a predetermined positional relationship is established with respect to the frame 31, and the height is defined by the cartridge guide 41 and the boss 42, the loading of the cartridge 4 into the magnetic recording / reproducing apparatus is completed.

During this loading, the spring of the cam plate 32 is attached to the receiver 33.
The spring force in the direction of arrow C is exerted by 47, whereby the receiver 33 presses the upper surface of the cartridge 4, and the height of the cartridge 4 is regulated by the cartridge guide 41 and the boss 42. Therefore, the receiver pin 45 is shown in FIG.
As described above, the guide groove 31b does not fall to the lower end, and stops halfway.

On the other hand, in conjunction with the movement of the cam plate 32 in the direction of arrow A, the cam plate 32
The conversion lever 38 connected to the connecting piece 32d of the above rotates in the direction of arrow E. Since the conversion lever 38 is connected to the slide plate 37 via the interlocking pin 40, the slide plate 37 moves forward in the direction of arrow B. Next, the ejecting operation will be described. When the slide plate 37 which has moved forward is pushed and moved in the direction of arrow A, the operation reverse to the loading operation is performed. That is, by the movement of the slide plate 37 in the direction of arrow A, the conversion lever 38 engaged with the slide plate 37 rotates in the direction of arrow F,
32 moves in the direction of arrow B against the spring 47. By this movement, the receiver pin 45 moves from FIG. 4 (c) to FIG. 4 (b), so that the receiver 33 and the cartridge 4 are integrally lifted in the direction of arrow D. In addition, receiver pin 45
Moves from Fig. 4 (b) to (a), so the receiver
33 and the cartridge 4 move in the direction of arrow B.

At this time, the side face 36c of the cam plate hook 36 is in contact with the contact piece 32e of the cam plate. However, since the cam plate 32 moves in the direction of arrow B, the cam plate 32 is urged to rotate in the direction of arrow E by the spring 48. The cam plate hook 36 has a hook piece 36a whose cam plate 3
The second contact piece 32e contacts the second contact piece 32e. In addition, a cartridge hook
Since the engaging piece 34b of the 34 comes into contact with the cutout surface 31d of the frame 31, the cartridge hook 34 rotates in the direction of arrow E against the spring 52. By this operation, the cartridge 4 locked by the engagement piece 34a of the cartridge hook 34 is opened. Then, since the pressing piece 35b of the eject lever 35 pushes out the cartridge 4 by the spring force of the eject spring 46, the cartridge 4 is automatically ejected in the direction of arrow B.

[Problems to be solved by the invention]

The conventional external storage device has a structure in which the ejecting operation of the slide plate 37 causes the cam plate 32 to slide with respect to the frame 31 to eject the cartridge 4.

The structure is complicated,
There was a problem that fabrication was difficult. In addition, the slide plate 37, which is an operation member for ejecting, pushes into the frame 31, while the cam plate 32 ejects the cartridge 4 by moving in the opposite direction. A conversion lever 38 for connecting them is required. Therefore, the number of parts is large and the power transmission efficiency is poor.

The present invention has been made in view of such a problem, and provides an external storage device of an electronic information device that enables an ejection without the need for sliding movement and has a simple structure with a small number of components. With that purpose.

[Means for solving the problem]

To rotate the cam member And the slide member, the slide member, characterized in that it comprises a spring for biasing the eject direction of the medium.

[Action]

According to this configuration, when the media is pulled in, the media is inserted into the receiver, and when the slide plate is slid in the ejecting direction of the media by the spring, the cam member rotates and the receiver moves in the media inserting direction with respect to the frame. After sliding, it is possible to slide in a direction perpendicular to this. On the other hand, when ejecting the media, when the slide member is slid in the media insertion direction against the spring force, the cam member rotates, and the receiver slides in a direction perpendicular to the media eject direction with respect to the frame. Thereafter, it is possible to slide in the ejection direction.

At the same time, since the receiver pin 16 moves in the direction of arrow C, the front positioning hole 4a of the cartridge 4 fits into the corresponding front cartridge guide 11. This completes the loading of the cartridge 4 as shown in FIG. 2 (d).

Such a series of operations is performed by the spring force of the spring 23 of the slide plate 9, and the slide plate 9 advances in the direction of arrow B and stops. The moving amount of the slide plate 9 is L ₁ −L ₂
(See FIG. 2).

(2) Ejecting the cartridge In the state shown in FIG. 2 (d), the eject button is pushed and the slide plate 9 is pushed in the direction of arrow A. By the movement of the slide plate 9, the cam lever 2 connected via the interlocking pin 10 rotates in the direction of arrow G. And
When the cam lever 2 rotates to the position shown in FIG. 2C, the lever portion 2c of the cam lever 2 and the guide piece 3c of the receiver 3 come into contact with each other. Operates to lift. When the lifting of the rear portion is completed, the receiver pin 16 moves from the guide groove 1b of the frame 1 to the guide groove 1a and the balance piece 3d of the receiver 3 is placed on the receiver receiver 12, as shown in FIG. Abut At the same time, the receiver pin 16 moves in the guide groove 1a of the frame 1 in the direction of arrow B, and at the same time, the receiver 3 moves in the direction of arrow B, and the receiver hook 6 which has been released in the direction of arrow H by the ejecting member 5 until then moves to the arrow Starting to return in the G direction, the action piece 6b abuts on the lock piece 3b of the receiver 3.

When the receiver 3 further moves in the direction of arrow B, the action piece 6b of the receiver hook 6 slips off from above the lock piece 3b and comes into contact with the rear end face of the lock piece 3b.
The movement in the direction is locked. At the same time, the operation piece 6a of the receiver hook 6 comes into contact with the pin 17 on the frame side, so that the rotation of the receiver hook 6 stops. further,
Cartridge hook 7 attached to receiver 3
Since the engagement piece 7b abuts on the cutout surface 1e of the frame 1, the arm rotates in the direction of arrow E against the spring 20. As a result, the engaging piece 7a of the cartridge hook 7 that has been engaged with the engaging hole 4f of the cartridge is released from the engaged state. For this reason, the cartridge 4 is released from the cartridge hook 7, is moved in the direction of arrow B by the ejecting member 5, is ejected from the receiver 3, and enters the state shown in FIG. 2 (a).

In the above configuration, the cam lever 2 is pivotally attached to the frame 1 by the bearing hole 1d.
The cartridge 4 is ejected by rotating the receiver 3 in the direction of the arrow B by rotating the receiver 3 in the direction of the arrow A simultaneously with the movement of the receiver 3 in the direction of the arrow A by the insertion of the cartridge 3. Therefore, the cam lever 2 does not slide with respect to the frame 1, so that a guide member for sliding is not required, and play in design is not required. Therefore, the desired operation can be performed with a simple structure. Also,
The cam lever 2 is directly connected to a slide plate 9 for ejecting operation by an interlocking pin 10, and can directly transmit the sliding movement force of the slide plate 9 and the spring force of the spring 23 to the receiver 3. Therefore, the ejection operation can be performed with good transmission efficiency and light touch.

In the above embodiment, the description has been given of the floppy disk drive. However, it goes without saying that the present invention can be applied to an optical disk drive or the like.

〔The invention's effect〕

As described above, the present invention slides the receiver by converting the spring force by the cam member rotatably attached to the frame, so that the cam member does not need to be slid, and the structure is simplified and the conversion is simplified. No special member is required, and the number of parts can be reduced.
