Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk device for recording / reproducing information while being stored in a disk stored in a case, and particularly to a case mounting / discharging case. It concerns the mechanism.

[Conventional technology]

Generally, in a disk device, when inserting a case,
The case inserted into the case holder (that is, the case containing the disc) is mounted at a predetermined position by the case holder, and at the time of discharging the case, the mounted case is detached from the position by the case holder. A mechanism for discharging from the holder, that is, a case mounting / discharging mechanism is required.

On the other hand, in a disk device using a 3.5-inch flexible magnetic disk, for example, a shutter for covering the opening and a shutter sensor notch (having a concave shape) for detecting the open / closed state of the shutter are provided in a case for storing the disk. Since it is provided, a shutter opening / closing mechanism is required in addition to the case mounting / discharging mechanism described above.

This shutter opening / closing mechanism opens and closes a shutter of the case in accordance with insertion / ejection of the case, and when the shutter is opened, a shutter engaging portion of the shutter opening / closing mechanism engages with a shutter sensor notch forming a concave shape of the case. Then, the case is fixed, that is, in an auto-lock state.

When the case is ejected, the case can be released by releasing the shutter engagement portion from the shutter sensor notch by pushing the case out by some means when the case is ejected. Therefore, in the case mounting / discharging mechanism used together with the shutter opening / closing mechanism as described above, a case pushing function for pushing the case when ejecting the case is required.

A conventional case mounting / discharging mechanism having such a case pushing function is disclosed in, for example, Japanese Patent Application Laid-Open No. 60-1479.
There is one described in No. 65.

Hereinafter, this conventional example will be described with reference to FIG.

FIG. 5 is a perspective view showing a conventional case mounting / discharging mechanism.

In FIG. 5, reference numeral 101 denotes an eject plate for lowering and raising a case holder (not shown) for holding a case (not shown) in accordance with mounting and discharging of the case, and reference numeral 102 denotes a case insertion standby position for the eject plate 101.

In FIG. 5, when the case is inserted, the pop-up plate 103 is pushed by the case and moves in the direction of arrow A. At this time, the pop-up plate 103 rotates the eject plate latch plate 102. Thereafter, the pop-up plate 103 is fixed by the pop-up plate latch plate 104 in the moved state. In addition, by the rotation of the eject plate latch plate 102, the eject plate 101 is released from the fixed state, moves in the direction of arrow B by the biasing force of the spring, lowers the case holder, and mounts the case in a predetermined position. I do.

When discharging the case, the operator moves the eject plate 101 in the direction of arrow A against the urging force of the spring. As a result, the eject plate 101 raises the case holder, and then the eject plate latch plate
The pop-up plate latch plate 104 is rotated while being fixed again by 102. The pop-up plate 103 is released from the fixed state by the rotation of the pop-up plate latch plate 104, moves in the direction of arrow B by the biasing force of the spring, and pushes the case in the direction of arrow B.

[Problems to be solved by the invention]

The conventional case mounting / discharging mechanism shown in FIG. 5 has a problem that the number of components such as the eject plate 101, the eject plate latch plate 102, the pop-up plate 103, and the pop-up plate latch plate 104 is large and the configuration becomes complicated. Was.

FIG. 6 is a side view showing a state where the case is mounted in the case mounting / discharging mechanism of FIG.

In FIG. 6, 105 is a chassis, and 106 is a case. Note that other eject plates 101 and the like are omitted.

As shown in FIG. 6, in the conventional case device / discharge mechanism shown in FIG. 5, an eject plate 101, an eject plate latch plate 102, a pop-up plate 103 are provided between a chassis 105 and a case 106 to be mounted. Since the pop-up plate latch plate 104 is provided, there is a problem that the height of the entire disk device is increased by the height h.

A first object of the present invention is to solve the above-mentioned problems of the prior art, to reduce the number of parts, and to install the case in a simple configuration.
It is to provide a discharge mechanism.

A second object of the present invention is to provide a case mounting / discharging mechanism capable of reducing the thickness of a disk device.

[Means for solving the problem]

In order to achieve the first object, the present invention provides:
A case holder for holding the case containing the disc,
A case mounting / ejecting device comprising: a rotary driving means for driving the disk to rotate; and a slider which is mounted and removed between the disk and the rotary driving means by moving in a case insertion / ejection direction. When the slider is not inserted into the case holder, the slider is held. When the case is inserted into the case holder, the slider operates in a predetermined direction (hereinafter, referred to as a first direction) by the case, The holding of the slider is released to allow the slider to move, and when the disk is detached from the rotation driving means, the direction is opposite to the first direction (hereinafter, referred to as a second direction). , The case is ejected from the case holder by pushing out the case, and case detecting means for holding the slider is a case holder. To be provided.

Further, in order to achieve the second object, in the present invention, the trigger lever is attached to the case holder so as to be rotatable around a certain axis.

[Action]

The trigger lever operates in the first direction by the case when the case is inserted into the case holder, and detects the insertion of the case. When the case is detached from a predetermined position by the case holder, the case is operated in the second direction, and the case is ejected from the case holder by pushing the case.

Therefore, the trigger lever not only senses the insertion of the case at the time of mounting, but also pushes the case at the time of ejection, and is a component used exclusively for pushing the case, such as a conventional pop-up plate and pop-up plate latch plate. Is unnecessary, and therefore, the number of components can be reduced, and the configuration of the case mounting / discharging mechanism can be simplified.

Further, when the trigger lever is attached to the case holder so as to be rotatable around a certain axis, the trigger lever is moved by the case when the case is inserted into the case holder. By rotating in the direction, the insertion of the case is sensed. Further, when the case is separated from the position by the case holder, the case is pushed out by rotating in the second direction.

In this case, since the trigger lever is attached to the case holder, a space for disposing components of the case mounting / discharging mechanism is not required between the chassis and the mounted case. The disk device can be made thinner. Further, since no space is required on the chassis for disposing the components of the case mounting / discharging mechanism, the degree of freedom in designing the head transfer access mechanism and the like provided in the chassis is increased.

In addition, the trigger lever is always urged in the second direction by an urging means, and is brought into contact with a stopper portion of the case holder until the trigger lever is rotated in the first direction by the case. You may.

In this case, the rotation of the trigger lever in the second direction is restricted by the stopper portion until the case is inserted into the case holder and the case is rotated in the first direction by the case. . When the case is separated from the position by the case holder,
The case is rotated in the second direction by the urging force of the urging means, and the case is pushed out. Then, the case is again brought into contact with the stopper portion and the rotation in the second direction is regulated.

Also, by preparing a slider movably attached in the insertion direction and the discharge direction of the case, and urged in the insertion direction or the discharge direction of the case, by driving the case holder by moving the slider, The case is mounted at the position, or the mounted case is detached from the position. Until the trigger lever detects the insertion of the case, the trigger lever regulates the movement of the slider in the biasing direction. After the case is mounted, the state of the trigger lever is held by the holding portion of the slider.

The slider is restricted from moving in the biasing direction by the trigger lever until the trigger lever detects the insertion of the case.
Move in the biasing direction. Thereby, the case holder mounts the case at the position. After the case holder has mounted the case, the trigger lever is held in a state separated from the case by the holding portion of the slider. At the time of discharge, the slider is moved by the operator in a direction opposite to the urging direction, so that the case holder detaches the case from the position.

At this time, the state of the trigger lever 4 is the insertion standby state of the case 1, the case lever abutment part 4 a of the trigger lever 4 abuts against the stopper part 3 a of the case holder 3, and the rotation of the trigger lever 4 due to the urging force of the spring 15 is Has stopped.

The load lever contact portion 4c of the load lever 6 is in contact with the load slider contact portion 4c of the trigger lever 4. As a result, the load slider 6 is fixed at the position shown in the figure despite the urging force of the spring 13.

Hereinafter, the position of the load slider 6 at this time is referred to as an initial position, and the state of the trigger lever 4 is referred to as an initial state.

When the case 1 is further inserted in the direction of arrow A, (b)
The case 1 is a case contact portion 4b of the trigger lever 4 as shown in FIG.

When the case 1 is further inserted in the direction of arrow A, the trigger lever 4 is pushed by the case 1 as shown in FIG. As a result, the load slider contact portion 4c of the trigger lever 4 is
The load slider 6 is moved in the direction of arrow A slightly.

When the insertion operation of the case 1 is completed, the load slider contact portion 4c of the trigger lever 4 is disengaged from the trigger lever contact portion 6d of the load slider 6 as shown in FIG. The case 1 and the magnetic head 5 move in the direction of arrow B by the urging force of the spring 13.
Is lowered, and the disk is mounted on the disk rotation drive means. At this time, the biasing force of the spring 15 acts on the trigger lever 4, but as shown in (e), the load slider contact portion 4 c of the trigger lever 4 contacts the trigger lever holding portion 6 e of the load slider 6 and is regulated. Therefore, the trigger lever 4 is fixed so as not to contact the case 1.

Next, the operation of discharging the case 1 will be described with reference to FIG.

In FIG. 4, (a) the state when the disk is mounted,
(B) is the state when the load slider 6 is moved to the initial position, (c) is the state when the load slider 6 is further moved, and (d) is the state when the trigger lever 4 contacts the case 1. (E) shows the state when the trigger lever 4 pushes out the case 1, and (f) shows the initial state of the trigger lever 4 after pushing out the case 1.

When the case 1 is ejected, the operator pushes the eject button 6f of the load slider 6 in the direction of arrow A, thereby causing the load slider 6 to move in the direction of arrow A as shown in FIG.
Moved in the direction. Thereby, the magnetic head 5 and the case 1 are raised. At this time, the load slider contact portion 4c of the trigger lever 4 is connected to the trigger lever holding portion 6e of the load slider 6.
And the case contact portion 4b of the trigger lever 4

At this time, the contact portion 4b of the trigger lever 4 is separated from the case 1.

When the operator further pushes the eject button 6f of the load slider 6 in the direction of arrow A, and the load slider 6 is further moved in the direction of arrow A, the load slider contact portion of the trigger lever 4 as shown in FIG. 4c is disengaged from the trigger lever holding portion 6e of the load slider 6, and the trigger lever 4 starts rotating in the direction of arrow C by the urging force of the spring 15. As a result, the case contact portion 4b of the trigger lever 4
As shown in (d), it acts on the case 1 so as to push the case 1 in the direction of arrow B (the direction opposite to the insertion direction).

Then, the trigger lever 4 has its case holder contact portion 4a.
Rotates until it comes into contact with the stopper portion 3a of the case holder 3, and at the same time, the case 1 is pushed out by the stopper contact portion 4b of the trigger lever 4 and discharged from the case holder 3, as shown in FIG. In (e), the trigger lever 4 and the load stopper 6 are separated from each other because the operator still keeps pushing the eject button 6f of the load slider 6 in the direction of arrow A.

Then, when the operator stops pressing the eject button 6f of the load slider 6, the load slider 6 moves in the direction of arrow B by the urging force of the spring 13 as shown in FIG. It comes into contact with the load slider contact portion 4c of the trigger lever 4. Thereby, the trigger lever 4 is
The initial state is again the same as that shown in FIG. 3A, and the state is awaiting insertion of the case 1.

According to the present embodiment, the trigger lever 4 not only fixes the load slider 6 to the initial position at the time of waiting for the insertion of the case 1 but also pushes the case 1 at the time of ejecting the case. A component such as a latch plate used exclusively for pushing out the case is not required, so that the number of components is reduced and the configuration of the case mounting / discharging mechanism can be simplified.

Further, according to the present embodiment, the trigger lever 4 is provided inside the case holder 3 and on the far side with respect to the insertion direction of the case 1, and even when the case 1 is mounted, the trigger lever 4 is provided.
Is not located between the chassis 11 and the mounted case 1. Therefore, a base for disposing the components of the case mounting / discharging mechanism between the chassis 11 and the mounted case 1 is unnecessary, and the height of the magneto-optical disk device can be reduced by the height of the base. In addition, since the components of the case mounting / discharging mechanism are not disposed above the case holder 3, the space above the case holder 3 can be effectively used.

In the present embodiment, the trigger lever 4 is attached to the case holder 3 in order to reduce the thickness of the magneto-optical disk device. However, the present invention is not particularly limited to this, and the trigger lever 4 is attached to other parts. Is also good.

〔The invention's effect〕

As described above, according to the present invention, the trigger lever
