Abstract

PURPOSE:To easily eject a cartridge by manual operation when an electric fault takes place by pushing a rod by hand externally so as to lift a cassette holder thereby ejecting the cartridge. CONSTITUTION:When a cartridge is ejected, a rod 2 is pushed in by hand against a force of a return spring 8. In this case, since a hook 4 is also depressed, a bound of a pin 3a by a hammer rod 3 by a claw of the hook 4 is released, an eject spring 9 is shortened and the hammer rod 3 is moved to the left (direction of arrow mark B). A loading plate 10 is moved also in the direction of the arrow mark B by a motion of the hammer rod 3 and a groove 10a of the loading plate 10 guides a shaft 11a of a cassette holder 11 and to lift it. As a result, the cassette holder 11 is lifted to eject the cartridge.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk device in which a cartridge containing an optical disk medium is mounted to record or reproduce information.

[0002]

2. Description of the Related Art A conventional optical disk device for recording or reproducing information by mounting a cartridge containing an optical disk medium has an optical disk loading device for ejecting the cartridge by electrically operating. If an electrical failure such as a failure of a related electric circuit or a power failure occurs, the cartridge cannot be ejected. At this time, as means for ejecting the cartridge,
A means of inserting a thin pin and ejecting the cartridge by the force of inserting the pin at that time is adopted.

[0003]

As described above, the conventional optical disk device has a means for ejecting the cartridge by inserting a thin pin when an electrical failure such as a defective electric circuit or a power failure occurs. Since it is adopted, the burden on the user is heavy, and a thin pin has to be inserted deep into the device, which has the drawback of giving psychological anxiety to the user.

[0004]

An optical disk apparatus according to the present invention comprises a cartridge holder for holding a cartridge containing an optical disk medium, a loading plate for moving the cartridge holder up and down, and a drive for driving the loading plate. An optical disk loading device having an optical disk loading device having a section, and a spring that is extended and held in that state when the cartridge is mounted on the cassette holder and a load down is performed; The cartridge ejecting mechanism section has a rod for releasing the coupled state of the loading plate and the driving section and releasing the holding state of the spring to raise the cassette holder and eject the cartridge.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is an exploded perspective view showing an embodiment of the present invention, FIG. 2 is a plan view showing an operating state of the embodiment of FIG. 1, and FIG.
[Fig. 2] is a front view showing an operation state of the embodiment of Fig. 1.

In FIG. 1, a gear base 1 is provided with a rod 2 and a hammer rod 3 in the front-rear direction (longitudinal direction) thereof.
Is movably attached to. Further, the motor bracket 6 to which the hook 4 and the load motor 5 are attached and the gear train 7 are attached to be rotatable or rotatable. The tip of the rod 2 is engaged with the motor bracket 6 (details will be described later), and the motor bracket 6 rotates as the rod 2 moves in the front-rear direction. A return spring 8 is attached to the rear end of the rod 2.
An eject spring 9 is attached to the rear end of the hammer rod 3.

The rotation of the funnel motor 5 is transmitted to the output gear 7a at the tip thereof via the gear train 7. Output gear 7a
Is a rack 10 provided on the loading plate 10.
When the load motor 5 rotates because it meshes with a,
The loading plate 10 is driven in the front-back direction.

The cassette holder 11 for holding the cartridge containing the optical disk medium has a shaft 11a provided on the side surface thereof engaged with an inclined groove portion 10b provided on the side surface of the loading plate 10, so that the cassette holder 11 is loaded. When the plate 10 moves in the front-back direction, the shaft 11a
Is guided to the groove portion 10b, and the cassette holder 11 moves in the vertical direction.

Next, the operation of the optical disk loading device of the optical disk device configured as described above will be described with reference to FIGS. 2 and 3.

As shown in FIG. 2 (a), a pin 4 a provided at the rear end of the hook 4 is fitted in a long hole 2 a provided at the center of the rod 2, and at the tip of the rod 2. A pin 6a provided on the motor bracket 6 is fitted in the provided groove 2b. On the other hand, in the hammer rod 3, when the eject spring 9 is extended, the pin 3a provided at the tip of the hammer rod 3 engages with the claw portion at the tip of the hook 4, and the movement thereof is stopped. In this state,
A worm gear 5a attached to the shaft of the load motor 5 meshes with the gear train 7.

To eject the cartridge, the rod 2 is manually pushed in this state in the direction of arrow A in FIG. 2B against the force of the return spring 8. As a result, the motor bracket 6 rotates in the direction of arrow C about the center shaft 12 because the pin 6a is guided by the groove 2b at the tip of the rod 2. This makes the worm gear 5
The meshing between a and the gear train 7 is disengaged.

When the rod 2 is further pushed in, the motor bracket 6 continues to rotate as shown in FIG.
Also, since the pin 4a is pushed by the elongated hole 2a, the pin 4a rotates about the center shaft 13 in the arrow D direction. By this movement of the hook 4, the pin 3a of the hammer rod 3 is released from the constraint by the claw portion of the hook 4, so that the eject spring 9 is shortened and the hammer rod 3 is moved leftward (in the direction of arrow B).
Move to.

As a result of the movement of the hammer rod 3, FIG.
As shown in (a), the hinge 1 in which the hammer portion 3b of the hammer rod 3 is provided on the lower surface of the loading plate 10
0c, and the loading plate 10 also moves in the direction of arrow B. When the loading plate 10 moves in the direction of arrow B, as shown in FIG. 3B, the groove portion 10 a of the loading plate 10 is moved to the shaft 11 of the cassette holder 11.
In order to guide and raise a, the cassette holder 11 rises (direction of arrow E) to eject the cartridge.

When the rod 2 is opened after the ejection of the cartridge is completed, the rod 2 returns to the original standby state by the force of the return spring 8. In this state, when the cartridge is attached to the cassette holder 11 to perform the load down,
Since the loading plate 10 is moved to the right,
The hinge 10c of the loading plate 10 pushes the hammer portion 3b of the hammer rod 3 while extending the eject spring 9, and the pin 3a of the hammer rod 3 is engaged with the claw portion of the hook 4 to restrain the hammer rod 3. As a result, the hammer rod 3 also enters the standby state.

[0016]

As described above, in the optical disk device of the present invention, when the cartridge is mounted on the cassette holder and the load is down, the spring is extended and held in that state, and the rod is manually operated from the outside. By pressing the to open the spring and raise the cassette holder to eject the cartridge, you can easily eject the cartridge manually when an electrical failure such as a defective electric circuit or power failure occurs. Therefore, it is possible to eliminate the psychological anxiety of the user.
