The spring force of the torsion spring 56 is cammed via the roller 58.
It acts on the first cam surface 60a of the part 60. The engaging portion 24b of the locking member 24
Is released, and the cover 14 rotates upward.
Get started. With the rotation of the cover 14 in the opening direction,
The roller 58 is, as shown in FIG.
The first cam surface 60a rolls and comes into contact with the step portion 60b. At this stage, the step portion 60b of the cam portion 60 is
The contact of the roller 58 causes the cover 14 to open.
Limited. That is, a torsion supporting the roller 58
Rotation radius of spring 56 and rotation of stepped portion 60b of cam portion 60
Since the radius intersects, the step portion 60b of the cam portion 60
Is prevented from rotating in the opening direction by the rollers 58.
Therefore, the cover 14 is moved to the position of the locking member 24 as described above.
Even when the ejecting operation is performed, the roller 58 is
It stops at the half-open position where it contacts the part 60b. As described above, the cover 14 stops at the half-open position.

Medium, for example, in the unlocking operation state shown in FIG.
The power was turned off and the electric eject operation stopped halfway
In this case, the locking member 24 is stopped at the unlocked position.
Therefore, the cover 14 cannot be locked at the closed position. Like that
In this case, by rotating the operation pin 22 in the E direction,
The locking member 24 can be returned to the locking position.
You. FIG. 15 shows the state during the electric ejection operation.
If it stops in the operating state,

And the cam gear 32 rotates in the E direction, and the cam gear 32
Away from form 30 (tooth disengagement)
It becomes a rotation free state. Thus, the slide member 38 is
The cam portion 32c of the cam gear 32 is pushed by the spring force of the screw 46.
It moves in the direction C while pressing and reaches the locking position. At this time,
The cam gear 32 pushes the cam portion 32c against the slide member 38.
It is rotated in the E direction by being pressed. Thereafter, the operation on the operation pin 22 is released.
Then, the support arm 34 is thereby caused by the spring force of 6.
The cam gear 32 meshes with the worm 30

If the writing of the information has been completed, the process proceeds to S13.
Then, the ejection motor 28 is driven to rotate. This
The rotational driving force of the ejection motor 28 is
0 to the cam gear 32. Also, in S12
In this case, information is written by the optical pickup 18.
If so, the current process ends. The cam gear 32 rotates counterclockwise.
As a result, the cam portion 32c becomes the cam contact portion of the slide member 38.
38d, the slide member 38 is moved in the D direction.
Then, the locking of the cover 14 is released (see FIG. 15). That
Therefore, the cover 14 is

Make sure it is switched on. In S14,
When the slide member 38 reaches the unlocked position,
The contact portion 38f is connected to the movable section 39a of the position detection switch 39.
When the contact is made and the position detection switch 39 is turned on,
Proceeding to S15, the movable section 39a of the position detection switch 39
Check if is switched off. After releasing the lock of the cover 14,
When the gear 32 rotates, the cam portion 32c becomes a slide member.
38 is separated from the cam contact portion 38d. Therefore,
The id member 38 is moved in the C direction by the spring force of the coil spring 46.
And the contact portion 38f moves the position detection switch 39.
The position detection switch 39 is turned off by separating from the section 39a.
(See FIG. 16). In S15, the position detection switch 39
When the movable section 39a is switched off, the process proceeds to S16,
Turn off the power to the eject motor 28 to
The rotation drive by the table 28 is stopped. Then, the program proceeds to S17, in which a cover closing detection switch is operated.
Check if 49 has been turned on. Cover 1
4 corresponds to the spring force of the torsion spring 56 of the cover opening mechanism 54
When the cover is further opened, the detection pin 44 is set to the cover detection switch.
Closed lid detection switch 49 switches off at a distance from 49
Wrong. Therefore, in S17, the cover closing detection switch
When the switch 49 is turned off, the cover 14 is opened.
Judgment is made and the current process ends. Also in S17
When the lid detection switch 49 is kept on,
It is determined that the cover 14 is not opened, and the process proceeds to S20, and the alert
Emits a message. As a result, the operator opens the cover 14
Notice that there isn't, and investigate the cause. And the electrical system
If the cause is a failure, insert the operation pin 22 into the guide hole 11b.
(See FIG. 5) and rotate the cover 14 in the E direction to
