Abstract

PURPOSE:To protect a magnetic disk device by using an eject lever to make the motion of a loading operation means independent of the motion of a slide plate and not ejecting a disk regardless of application of careless force to the operation means at the time of inhibiting the disk ejection. CONSTITUTION:When a solenoid 7 is driven at the time of inhibiting the ejection, a latch plate 5 follows up the motion of a plunger 7a and is turned, and therefore, the plate 5 and a slide plate 3 do not come into contact with each other. Even if an eject button 1 is depressed at this time, an eject lever 2 is only moved but a cassette cannot be ejected.

Description

[Detailed description of the invention] (Industrial application field) TECHNICAL FIELD This invention relates to a magnetic tissue device.

(Prior Art) Fig. 6 is a perspective view of a slide plate of a conventional magnetic disk device (hereinafter referred to as the device), and Fig. 7 is a small blade side view of the conventional device in a state where the disk υ1 can be ejected. FIG. 8 is a plan view showing the disk JJ11' inhibited state of the conventional device.

6 to 8 of the drawings, 1 is an eject button, 13 is a slide plate, and a cam portion 13b that engages with the bottle portion 10a of the holster 10 (FIG. 3, described later) and an eject button are provided. It is being 13C (FIG. 8) is a contact portion that is provided integrally with the slide plate 13 and comes into contact with the plunger 14a of the solenoid 14. The solenoid 14 is fixed to the main body of the magnetic tisf device.

Next, the operation of this conventional example will be explained using FIGS. 7 and 8.

In FIG. 7 of the drawing, when the plunger 14a is moved to the left side of the paper as shown in the drawing by using the operating part (not shown) of the solenoid 14, if the issue button 1 is pushed upward in the paper, the slide plate 13 is also moved in the L direction. Movement 1 is performed, and Tisfu can be discharged (this explanation will be omitted)
. Also, in Figure 8 of the drawing, solenoid!・Plunger 14a as shown in the figure by using the operation part (not shown)
When the eject button 1 is moved to the right side of the page, the abutting portion 13c of the slide plate 13
However, it collides with the plunger 14a and cannot be moved, resulting in 11. (This explanation is omitted).

As explained above, in the conventional example, the mechanism for inhibiting the operation (1) and (11) by a signal from inside or outside the device fixed the movement of the slide plate 13 itself.

[Problem to be solved by the invention] As described above, in the conventional example, the eject button 1
Since it is directly connected to the slide plate 13,
If you try to forcefully press the eject button 1 in the state where the ejection is prohibited (Fig. 8), the solenoid 14
There is a problem in that the magnetic tisf device itself may be destroyed if the slide plate 13 is deformed or the slide plate 13 is deformed.

In addition, in order to solve this problem,
9274S discloses an improved technique for the above-mentioned magnetic tisf, but there are still problems such as the mechanism is complicated and it is difficult to incorporate it into the device.

This invention was made in order to solve the problems as described in 1.b. An eject lever is used as the mechanism for performing this operation, and the movement of the loading operation means is made independent of the movement of the slide plate. The purpose is to protect.

Another object of the present invention is to form the eject lever and the slide plate into a unit, so that even if a disk drive is equipped with a disk discharge prohibition mechanism, it can be installed as easily as a magnetic disk device without such a mechanism.

[Failure to solve the problem]

Therefore, in the present invention, there is provided a slide plate that reciprocates in one direction, a loading operation means that operates the slide plate to load or unload a magnetic disk, and a loading operation means disposed on the slide plate. The above object is achieved by a magnetic tisf device comprising: an eject lever which is provided and is reciprocated in the same direction as the slide plate; and a switching means for interlocking or non-interlocking the slide plate and the eject lever. This is what I am trying to do.

[Effect]

In the magnetic disk drive of the present invention, the switching means allows the slide plate and the eject lever to be interlocked or non-interlocked, the eject lever moves back and forth in the same direction as the slide plate, and the rotating operation means operates the slide plate reciprocating in one direction. Then do one of the rope ink and unloading of the magnetic disk.

〔Example〕

Hereinafter, a two-length embodiment of the present invention will be described based on the drawings.

FIG. 1 is a plan view showing a magnetic disk device according to a first embodiment of the present invention in a state in which disk ejection is prohibited, FIG. 2 is a plan view showing a state in which disk ejection is prohibited in the first embodiment, and FIG. A perspective view of the disk device, FIG. 4 is the second embodiment of the present invention.
FIG. 5 is a plan view showing the disk JJI prohibited state of the magnetic disk device according to the embodiment, and FIG. 5 is a plan view showing the disk ejection +1J enabled state of the second embodiment.

In FIGS. 1 and 2, A is a loading operation means, which is composed of an eject button 1, and loads and unloads a magnetic disk (not shown) by operating a slide plate 3 that reciprocates in one direction. (details will be described later). Reference numeral B denotes a switching means, which is composed of a solenoid 7 (described later) and a latch plate 5 (described later), and is a means (described later) for interlocking or non-interlocking the slide plate 3 and the eject lever 2.

In addition, in FIGS. 1 and 2, 1 is an eject button, 2 is an eject lever directly connected to the eject button, and 3 is a slide plate, which moves the magnetic disk to the 11th line upper position for writing or reading. For this purpose, a cam portion is provided on the side surface. Reference numeral 4 denotes an eject lever spring, which is applied to the slide plate 3- to bias the eject lever'-2 in the direction of the eject button. 5 is an eject) and a latch play 1 to .5 is rotatably arranged on the lever 2. 6 is a latch spring that biases the latch plate 1-5 counterclockwise in the figure, 7 is a solenoid for rotating the latch plate 5, and 2a is a stopper for the latch lever 5 disposed on the eject lever 2. 3a is the contact part of the slide plate 3 with the latch lever 5, 5a is the contact part of the latch lever 5 with the slide plate 3, 5b is the contact part of the crawler lever 5 with the stopper 2a, and 7a is the solenoid. The plunger 7b is a solenoid spring that urges the plunger 7a to the right in the figure.

FIG. 3 is a perspective view of the magnetic disk drive before the magnetic disk is inserted, in which 8 is the head of the magnetic disk, 9 is the front panel, 10 is a holder for holding the magnetic disk, 9
a is a magnetic disk insertion provided on the front panel 9; 1, 10a is a pin portion of the halter 10 that engages with the slide plate 3;

Further, a cam portion similar to the cam portion 13b of FIG. 6 in the conventional example is also provided in the slide plate 3 of this embodiment.

Next, the operation of the first embodiment will be explained using FIGS. 1 and 2.

Before this explanation, the rope ink and unloading of the magnetic disk by the rope ink operating means will be explained with reference to FIGS. 3 and 4.

First, I will explain about rope ink.

When a magnetic disk (not shown) is inserted into the magnetic disk drive in the state shown in FIG. 3, it is moved toward the slide plate 13 or the front panel 9 by a rope ink mechanism (boo not shown).

Along with this, the holder 10 holding the magnetic disk moves downward in the figure along the cam portion 13b, fixing the magnetic disk at a readable or writable position.

Next, unloading will be explained.

From this state, press the eject button 1 and move the slide play) 13 in the direction opposite to the front panel 9. At the same time, the halter 10 moves upward in the figure along the cam part 13b, and the rope The slide play 13 is fixed by the ink mechanism (Figure/Fake-4'') and the magnetic disk is ejected.

Next, the operation of the first embodiment will be explained.

In the first embodiment, the slide plate unit shown in FIGS. 1 and 2 is used in place of the slide plate 13 shown in FIG. 6 of the drawings.

Since the steps from inserting the magnetic disk to fixing the cassette in a readable or writable state are as described above, the explanation thereof will be omitted.

FIG. 1 of the drawings of this embodiment shows a state in which the cassette cannot be ejected even if the solenoid 7 is driven and the eject button 1 is pressed, and FIG.
This shows a state where normal cassette ejection is possible.

The eject lever 2 is provided on a slide plate 31- so as to be movable in the vertical direction in the figure.
It is energized in the downward direction in the figure.

The latch plates 1 and 5 are rotatably installed on the eject lever 2-1, and are energized counterclockwise in the figure by the latch spring 6, so that the plunger 7a of the solenoid 7
is in contact with

The latch spring 6 is set to be weaker than the solenoid spring 7b. The tip of the solenoid in contact with the latch plays 1 and 5 is in an R state.

Solenoid 7, plunger 7a, solenoid blade 7b
1 and 2 are all incorporated into the slide plate 30 and are unitized.

As shown in FIG. 1, when the solenoid is being driven, the latch plate 5 follows the movement of the plunger 7a and rotates 1-, so the latch plate 5 and slide plate 3 do not come into contact with each other. At this time, even if the eject button 1 is pressed, only the eject lever 2 moves, and the slide plate 3 does not move. Therefore, even if you can press eject button 1, the cassette)
I can't go out.

In addition, as shown in FIG. 2 of the drawings, when the solenoid 7 is not driven and is in a released state, the portion 5a of the sliding plate 5 is attached to the slide plate 3a portion due to the biasing force of the solenoid spring 7b and the biasing force of the latch spring 6. The slide plate 3 can be moved by pressing the eject button 1. Therefore, it is possible to output the cassette υ1 as in the conventional example.

Note that the solenoid 7 is driven by the 4 inside the magnetic tisf device, which is linked to the read/11: write signal.
No. 11 may be used, or a signal external to the magnetic disk device, such as from a system equipped with a magnetic disk device, may be used.

Next, regarding the second embodiment of the present invention, FIGS.
This will be explained using figures.

The process from inserting the magnetic disk to fixing the cassette in a readable or writable state is the same as described above.

FIG. 4 shows a state in which the cassette cannot be ejected even if the solenoid 7 is driven and the eject button 1 is pressed.

FIG. 5 shows a state in which the solenoid 7 is released and normal cassette ejection is possible.

The eject lever 11 has a slide plate 30. It is provided so as to be movable in the vertical direction and rotated in the figure, and is biased in the figure direction and clockwise by the eject lever spring 4.

Further, the eject lever 11 is in contact with the plunger 7a, and the component force acting on the rotation of the biasing force of the eject lever spring 4 is set to be weaker than that of the solenoid spring 7b.

Next, the operation of the second embodiment will be explained using FIGS. 4 and 5.

In FIG. 4, when the solenoid 7 is being driven, the eject lever 1 is moved by the movement of the plunger 7a.
1, the eject lever 11 and the slide plate 3 do not come into contact with each other. At this time, even if you press eject button 1, eject lever 1
1 only moves, and the slide plate 3 does not move.

Therefore, although the eject button 1 can be pressed, the cassette cannot be ejected.

Next, in FIG. 5 of the drawing, when the solenoid 7 is not driven and is in the released state, the contact portion 1 of the eject lever 11 is
1a is pressed by the abutment part 3a of the slide plate due to the difference between the rotational force of the solenoid spring 7b and the force of the eject lever spring 4, and the eject button 1 cannot be pressed. Therefore, the cassette can be ejected as described above.

In the case of this second embodiment, when the solenoid 7 is driven, the eject button 1 also moves in accordance with the rotation of the eject lever 11. However, since the center of rotation of the eject lever 11 is close to the eject button side,
The movement of the eject button 1 is slight compared to the movement of the contact portion between the eject lever 11 and the slide plate 3, and there is no problem in practical use.

〔Effect of the invention〕

As described above, in this invention, the eject lever is used as the mechanism for discharging the disk υ1, and the movement of the loading operation means is made independent of the movement of the slide plate.
The magnetic tissue device can be protected by the switching means even if an unexpected force is applied to the operating means when the fluid discharge is prohibited.

Moreover, by making the eject lever and slide play into a unit, even if a disk υF ejection inhibiting mechanism is included, it is possible to achieve the same ease of installation as a magnetic disk device without such a mechanism.
