Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention particularly relates to a floppy disk device that uses media housed in a hard case.

[Technical background of the invention and its problems] In recent years, floppy disk drives that use media (flexible magnetic recording media) housed in hard cases made of plastic or the like have been put into practical use. This floppy disk device is a small disk device that uses, for example, a 3.5-inch media, and has the great advantage of being able to be built into a device body such as a word processor or a small computer.

Incidentally, in such a floppy disk device, media are relatively frequently loaded and unloaded.

Therefore, it is necessary to perform media loading and ejecting operations easily and reliably. however,
In conventional floppy disk devices, the loading and ejecting mechanisms are complicated, resulting in problems such as an increase in the number of parts and difficulty in assembly. For this reason, it was decided that the reliability of the number of loading and ejecting units would decrease and the cost of the entire device would increase.

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to realize reliable loading and ejecting operations with a simple configuration in a floppy disk device that uses media stored in a hard case. The objective is to provide a floppy disk device that can.

[Summary of the Invention] In the present invention, a latch-like structure is provided that latches the eject plate at a predetermined position when unloading the media and releases the latch when loading the media.

The eject plate has the ability to move the receiver holding the medium downward and upward during loading and ejecting. Furthermore, a shutter opener-like structure is installed on the receiver, and this shutter opener-like structure opens the shutter installed on the media when the media is inserted, and causes the media to hop up when the media is ejected. It is composed of

With such a configuration, loading and ejecting operations of media can be performed reliably.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings. 1st
3 through 3 are perspective views showing the configuration of a floppy disk device according to one embodiment. First, a medium 20 as shown in FIG. 1 is loaded into and taken out from the floppy disk device main body 10. As shown in FIG. This media 20 is
It is housed in a hard case 21 made of plastic or the like, and a window 23 is opened and closed by opening and closing a shutter 22 provided in the hard case 21. Through this window 23, a magnetic head (not shown) in the disk device main body 10 comes into contact with the medium 20, and data read and write operations are performed. Further, a hub 24 made of plastic or metal is integrated into the center of the media 20. This hub 24 engages with a spindle (11a in FIG. 2) in the disk device main body 10, and the media 20 is rotationally driven. Further, the hard case 21 is provided with a positioning hole 25, and the hard case 21 is positioned in the media positioning bin 16 through the hole 25 when the media 20 is loaded.

The disk device main body 10 is equipped with a receiver 12 as shown in FIG.
0 (including the hard case 21).

The receiver 12 is held by a guide plate 13 attached to the frame 11 as shown in FIG.

That is, as shown in FIG. 3 (exploded perspective view), the receiver 1
A receiver bin 12a is attached to the guide plate 2, and the receiver bin 12a is held by a longitudinally elongated hole 13a of the guide plate 13, so that the receiver 12 can move in the vertical direction.

On the other hand, as shown in FIG. 2, an eject plate 14 is provided on the frame 11 in close proximity to the guide plate 13. This eject plate 14 is configured to be movable in the front-rear direction (horizontal to the vertical movement of the receiver 12) through a horizontal elongated hole 13b of the guide plate 13 shown in FIG. In this case, the eject plate 14 is connected to the long hole 13 of the guide plate 13 by the eject bin 14b fixed to the caulking hole 14a.
It will move along b. Further, the eject plate 14 includes an inclined hole 14C, and when the receiver bin 12a of the receiver 12 engages with the inclined hole 14C, the receiver 12 is moved in the vertical direction. That is, the inclined hole 140 is an elongated hole having an inclined portion formed so that the height from the frame 11 changes by a predetermined amount when the receiver bin 12a moves by a predetermined stroke.

Under normal conditions, the eject plate 14 is attracted forward (toward the media 20 insertion port 17 side) by a load spring 14d whose one end is fixed to the spring hook hole 13c of the guide plate 13.

As shown in FIG. 3, a latch bin 14e and an eject button 14f are fixed to predetermined portions of the eject plate 14, respectively. Ijiektobutan 14f
is a button that is operated when taking out the medium 20 from the disk device main body 10. Further, the latch bin 14e is held by a notch 15a of a latch plate 15 attached to the frame 11 when the media 20 is unloaded. The latch plate 15 rotates around a latch shaft 15b and is biased in a certain direction by a latch spring 15c. Furthermore, the latch plate 15 is provided with a PU bin 15d. This PU bin 15d rotates the latch plate 15 when inserting the media 20, and the eject plate 14
release the latch, and when ejecting, release the latch plate 15.
It has the ability to eject the medium 20 with its restoring force.

Generally speaking, as shown in FIG. 1, a shutter opener 18 is provided on the receiver 12. As shown in FIG. 3, this shutter opener 18 includes an opener bin 18a.
The shutter 22 of the media 20 is opened by the opener bin 18a. At this time, the opener bin 18a is held in a recess 2θ provided in the hard case 21 as shown in FIG. As shown in FIG. 1, the shutter opener 18 rotates around an opener shaft 18b and is biased in a fixed direction by an opener spring 18c. In addition, 16 shown in FIGS. 2 and 3
is a media positioning bin that engages with the positioning hole 25 of the hard case 21 to move the media 20 into the disk device main body 1.
Set to the predetermined position of 0 (drive). □ In a floppy disk device configured as above,
The operation according to one embodiment will be explained with reference to FIGS. 4 to 7. Here, FIG. 4 is a plan view, FIG. 5(a), and FIG.
Figures (a) and 7 (a) are front views, and Figures 5 (b), 6 (b), and 7 (b) are side views. First, in the unloaded state (FIGS. 4(a) and 5), the receiver 12 is positioned upward and the eject plate 14 is moved toward the back. At this time, the eject plate 14
As shown in FIG. 4(a), the latch pin 14e is engaged and latched by the latch plate 15.

In this state, the media 20 (along with the hard case 21)
When inserted into the disk device main body 10 from the insertion slot 17,
The shutter opener 18 comes into contact with the opener bin 18a and moves as shown in FIG. 4(a). As the shutter opener 18 moves, the shutter 22 of the media 20
is opened and the opener bin 18a enters the recess 2G of the medium 20 when the insertion is completed.

Shortly before the insertion of the medium 20 is completed, the hard case 21 comes into contact with the PU bin 15d of the latch plate 15, and the latch plate 15 begins to rotate. If the media 20 is roughly inserted, the notch 15a of the latch plate 15 will come off the latch bin 14e (FIG. 4(b)). By releasing the latch, the eject plate 14 is guided by the elongated hole 13b of the guide plate 13 by the suction force of the load spring 14d, and moves forward (toward the insertion port 17 side) by a predetermined stroke (Fig. 4(b) ), Figures 5 to 7). At this point, the receiver 12 moves downward (in the direction of the frame 11) because the receiver bin 12a is guided by the inclined hole 14C of the input plate 14 and the elongated hole 13a of the guide plate 13. Move to. As a result, the media 20 is attached to the spindle 11a.
It will be loaded into. At this time, the eject plate 14 is moving forward as described above, and the open nubbin IEla of the shutter opener 18 is moved toward the media 20.
It is in the recess 26 of. For this reason, the media 20
is latched in the loaded state.

Next, in order to remove the loaded medium 20, the eject button 14f is pressed in the direction of the arrow shown in FIG. 4(C). As a result, the eject plate 14 moves to the back, and the receiver 12 guided by the inclined hole 14C and the elongated hole 13a moves upward (Fig. 5).
. At this time, the latch bin 14 of the eject plate 14
e moves toward the back while rotating the latch plate 15. When the eject button 14f is continued to be pressed after the resino \12 has been raised, the latch bin 14e is moved to the notch 15a of the latch plate 15, as shown in FIG. 4 <C>.
latched to. At this time, the PU bin 1 of the latch plate 15
5d pushes the media 20 forward, and the opener bin 18a comes off from the recess 26 of the hard case 21. Therefore, the shutter opener 18 returns in the direction shown in FIG. 4(C), and the return force at this time causes the medium 20 to hop up. Then, the state returns to the unloading state shown in FIGS. 4(a) and 5.

In this way, the medium 20 can be loaded into the disk device main body 10 simply by inserting it through the insertion slot 17, and can be ejected from the disk device main body 10 by simply operating the eject button 14r. in this case,
Receiver 12, eject plate 14, latch plate 15
A relatively simple mechanism consisting of a latch mechanism such as the above, a shutter opener 18, etc., allows the operation of loading and ejecting the media 20 to be performed reliably. In particular, the launch plate 15 and notch 1 are important for loading and ejecting operations.
The latch mechanism consisting of the PU bottle 5a and the PU bottle 15d has a small number of parts and a simple configuration. Therefore, assembly work is simple and operation is reliable. Further, the opener bin 18a of the shutter opener 18 ensures that the loaded state of the medium 2° is maintained, and the medium 2° is hopped up at the time of ejection, thereby ensuring that it is ejected.

[Effects of the Invention] As described in detail above, according to the present invention, in a floppy disk device using media housed in a hard case, loading and ejecting operations for media can be reliably performed with a simple configuration. Therefore, there is an advantage that neither particularly complicated assembly work nor a large number of parts are required for loading and ejecting Im. This results in
As a result, the assembly process of the entire floppy disk device can be simplified and manufacturing costs can be reduced.

Furthermore, since the configuration is simple, there are fewer failures and reliable loading and ejecting operations can be achieved.
