Further, a slider 5 is housed inside the main body case 2. When the disc is ejected, the slider 5 is driven by the cartridge eject button 7. The cartridge eject button 7 is provided so as to protrude from the front panel 2a.

A cartridge holder 4 that holds the disk cartridge 1 is movably attached to the inside of the slider 5. The support pin 6 fixed to the side plate of the cartridge holder 4 passes through a guide groove 5a bored in the side plate of the slider 5. Furthermore, this support bin 6 is attached to the main body case 2.
It is provided so as to protrude from a long groove 2C that is elongated (extending) in the vertical direction in the figure, which is bored in the side plate 2b of the side plate 2b.In this way, the support bin 6 passes through the guide groove 5a and further extends into the long groove 2C.
Since the cartridge holder 4 protrudes from the cartridge holder 4, the cartridge holder 4 moves in the vertical direction in the drawing as the slider 5 moves in the horizontal direction in the drawing.

In this disk ejecting mechanism, when the cartridge ejecting button 7 is pushed into the front panel 2a during cartridge ejection, the slider 5 is driven to the right in the figure by the cartridge ejecting button 7. Then, the support bottle 6 will be relatively moved from point A at the lower end of the guide groove 5a to point B at the upper end, so it will move upward in the figure along the long groove 20. Therefore, the cartridge holder 4
In accordance with the operation of the support bin 6, the cartridge is raised from a disk rotation drive device close to a turntable (not shown) to a cartridge insertion/ejection position (the state shown in FIG. 8) facing the cartridge insertion opening 3. This allows the disk cartridge 1 to be inserted into the cartridge insertion slot 3.
It is designed to be taken out from

[Problems to be Solved by the Invention] However, as described above, the cartridge ejection button 7
In a conventional disk ejecting mechanism in which the disk is mechanically ejected by pushing in the disk, if the cartridge eject button 7 is pushed in while the disk is rotating, the disk cartridge 1 will be ejected while the disk continues to rotate.
could be ejected, potentially damaging the disc.

The present invention has been made with attention to such problems, and an object of the present invention is to provide a disk ejecting mechanism for a disk drive device that can prevent the disk from being ejected and damaged while the disk is rotating. do.

[Means to solve the problem]

The present invention provides a disk ejecting mechanism for a disk drive device in which a disk ejecting button protruding from a main body case is pushed into the main body case to move a disk holding part from a disk driving position to a disk ejecting position to eject a disk. The disk eject button includes a lock button that protrudes from the disk eject button when the disk is driven to prevent the disk eject button from being pushed into the main body case, and is pushed into the disk eject button when the disk is ejected; The present invention is characterized by being provided with a motor stop switch that stops the disk drive motor in conjunction with the pushing operation.

[Effect]

In the present invention, since a lock button is provided that protrudes from the disc eject button when the disc is being rotated, the disc eject button is prevented from being accidentally pushed into the main body case while the disc is rotating. In addition, in order to push in the disc button, it is necessary to push in the lock button, and when the lock button is pushed in, the motor stop switch is activated in conjunction with this.

Therefore, when ejecting the disk, the disk drive motor is reliably stopped before the disk eject button is pressed.

[Example] Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a partially sectional plan view showing a disk ejecting mechanism of a disk drive device according to a first embodiment of the present invention, and FIG. 2 is a perspective view showing the disk ejecting mechanism in a state in which a disk is inserted. 3 are perspective views showing the disk ejecting mechanism in a state in which no disk is inserted, and FIGS. 4 to 6 are plan views showing each operation of the disk ejecting mechanism of FIG. 1.

The basic structure of the disk ejecting mechanism according to the first embodiment is almost the same as that shown in the conventional example shown in FIG. That is, the front panel 11 of the main body case is provided with a disk insertion slot 11a into which a disk such as an optical disk or a floppy disk, or a disk cartridge containing the disk is inserted and ejected. Further, a disk eject button 12 protrudes from a hole 11b at the lower side of the disk insertion slot 11a. This disk eject button 12 drives a slider 5 as shown in FIG. A cartridge holder 4 that holds the disk cartridge 1 is movably attached to the inside of the slider 5. Alternatively, a disk holder including a disk mounting plate that moves between the inside and outside of the main body case 2 with the disk placed thereon may be movably attached to the inside of the slider 5.

On the other hand, a lock button 13 is located on the side of the disc eject button 12.
is installed protrudingly. This lock button 13 is pushed in the direction of arrow α in FIG. 1 so that it can be stored in the disc eject button 12.

Further, the disc eject button 12 has a built-in motor stop switch 14 connected to a drive circuit of a spindle motor (not shown) for driving the rotation of the disc via a lead wire 14a. This motor stop switch 14
The operating section 14b is fixed to the lock button 13. As a result, the motor stop switch 14 is configured to stop the spindle motor or allow it to rotate in conjunction with the pushing or protruding operation of the lock button 13. Further, a spring 15 is wound around the operating portion 14b between the motor stop switch 14 and the lock button 13 to bias the lock button 13 in the projecting direction (to the left in the figure).

Next, the operation will be explained.

When the disk is driven, the lock button 13 protrudes from the disk eject button 12, and this protrusion prevents the disk eject button 12 from being pushed in. When ejecting the disk, first, the lock button 13 is pushed in the direction of the arrow α in FIG. 1, and the operating portion 14b of the motor stop switch 14 is pushed to stop the rotation of the spindle motor. In this case, as shown in FIG. 4, the lock button 13 and the operation part 14b are
2, and the motor stop switch 14 is kept in a self-holding state. Push the disk eject button 12 in the direction of the front panel 11 (in the direction of the arrow β in FIG. 5). When you push it in, in the process,
As shown in FIG. 5, the end of the lock button 13 that slightly protrudes from the disk eject button 12 is pushed against the tapered surface 11c of the front panel 11, thereby unlocking the operating section 14b and turning the motor stop switch 14 on. Self-hold is released. When the disc eject button 12 is pushed all the way to the state shown in FIG.
It will be taken out from 1a.

Next, the operation when inserting a disc will be explained. Insert the disc (or disc cartridge) into the disc insertion slot 11 with no disc inserted, as shown in Figures 3 and 6.
When inserted from a, accordingly, as shown in Figure 5,
A disk eject button 12 protrudes from the front panel 11. At that time, since the lock button 13 has already been released from self-holding by the tapered surface 11C as described above,
It will completely protrude from the disc eject button 12 (
(See Figures 1 and 2).

Next, FIG. 7 is a partially sectional plan view showing a disk ejecting mechanism according to a second embodiment of the present invention.

In this second embodiment, a recess 2 is formed in the side wall of the front panel 21 in which a hole for protruding the disc eject button 12 is formed.
1a is provided. Also, inside the disc eject button 12, an abbreviated locking arm 22 is provided for supporting the bin 2.
3 is a fulcrum and is rotatable. When this locking arm is rotated clockwise in the figure, one end 22a thereof is fitted into the recess 21a.

Additionally, a lock button 24 is located on the left side of the disc eject button 12.
is installed protrudingly. A motor stop switch 25 is provided inside the disk eject button 12. The operating portion 25a of the motor stop switch 25 is fixed to the lock button 24 at one end and to the lower end portion 22b of the locking arm at the other end. Thereby, the locking arm 22 is configured to rotate counterclockwise and clockwise in the figure in response to the pushing and protruding operations of the lock button 24.

With the above structure, in this second embodiment, when a disc is inserted, the lock button 24 protrudes, and therefore the locking arm 22 rotates clockwise to lock the upper end. 22a is fitted into the recess 21a. Therefore, in this case, the pushing operation of the disc eject button 12 is blocked by the upper end portion 22a and the recess 21a.

On the other hand, when the disc is ejected, the motor is stopped by the motor stop switch 25 by pushing in the lock button 24. At the same time, the locking arm 22 rotates counterclockwise and the upper end 22a moves out of the recess 21a, allowing the disc eject button 12 to be pushed in.

Therefore, this second embodiment also provides the same effects as the first embodiment.

〔Effect of the invention〕

According to the present invention, it is possible to reliably stop the rotation of the disk before the disk ejection operation, and it is also possible to prevent the disk from being erroneously ejected while the disk is rotating. Therefore, it is possible to prevent the disk from being damaged by being ejected while it continues to rotate.
