2. Description of the Related Art Recording or reproducing apparatus, for example, having a diameter of about 6
2. Description of the Related Art There is a disk recording or reproducing apparatus which can mount a disk such as a 4 mm magneto-optical disk or a read-only optical disk on a disk table and perform recording or reproduction on the disk or both of them.

FIGS. 8 to 12 show an example of such a conventional disk recording or reproducing apparatus.

A disc recording or reproducing apparatus a has a main body b and a lid c rotatably supported by the main body b, and the main body b has a shallow box-like lower case d opened upward. And a mechanical chassis e disposed in the lower case d (see FIGS. 8 and 10).

A disk table f is mounted on the mechanical chassis e.
Required components such as an optical pickup (not shown) and the like are arranged. The disk table f is fixed to an upper end of a motor shaft h of a spindle motor g disposed below the disk table f, and is rotated by a driving force of the spindle motor g. A magnet (not shown) is embedded in the disk table f.

[0006] The front edge of the lower case d is formed as a step portion i whose inner portion is lowered by one step (see Fig. 10).
An engaging member j is supported movably in the A1-A2 direction shown in FIGS. The engaging member j is formed by integrally forming a vertical portion k extending vertically and an engaging portion 1 projecting rightward from an upper end of the vertical portion k. And the engaging portion l
Has an inclined edge m that is displaced downward as going to the right. The engaging member j is urged in the direction A1 by a spring member (not shown).

On the front surface of the lower case d, a slide knob n is slidably supported in the A1-A2 direction (FIG. 8).
reference). The slide knob n is formed by integrally forming an operated part o located on the front surface of the lower case d and a connecting part p projecting rearward from the operated part o, and a rear end of the connecting part p is engaged. It is connected to the lower end of the vertical part k of the joint member j. Therefore,
When the slide knob n is slid in the direction A1, the engaging member j is also moved in the direction A1, and when the slide knob n is slid in the direction A2, the engaging member j is also moved in the direction A2.

The lid c has a shallow box shape opened downward, and is rotatably supported by the lower case d with its rear end as a pivot point. A lock piece q protruding from the inner surface of the lid c is provided at the front end of the lid c. The lock piece q protrudes forward from the lower edge of the protrusion r protruding downward from the lid c and the lower end of the protrusion r. The lock portion s is integrally formed.

A holder t is provided below the lid c.
The holder t is rotatably supported by the rear end of the lid c. The holder t is opened forward, rearward, and downward, and has holding pieces u, u protruding from the lower edges of the left and right side surfaces in a direction approaching each other.

One end of a leaf spring member v is attached to the upper surface of the holder t, and the other end of the leaf spring member v is in elastic contact with the lower surface of the lid c (see FIG. 10). Therefore, the lid c and the holder t are urged by the leaf spring member v in a direction away from each other. The lid c and the holder t can rotate relative to each other with respect to the holder t and the lid c. However, when the lid c and the holder t are separated from each other by a predetermined distance, a coupling mechanism (not shown) causes the lid c and the holder t to move. When the cover t and the holder t are connected, the cover c and the holder t are integrally rotated while maintaining a predetermined distance.

The disk cartridge w is formed by rotatably storing a disk (not shown) in a case body, and a core made of a magnetic material is provided at the center of the disk.

When the disc cartridge w is inserted into the holder t to a predetermined position from the state in which the lid c is opened, the disc cartridge w is locked in the holder t by a cartridge locking mechanism (not shown), and the disc cartridge w is moved in the front-rear direction. Be regulated. When the lid c is pressed downward from this state, the lid c is rotated and moved substantially downward, and the disk cartridge w is moved with the movement of the lid c.
Is also moved downward.

By moving the holder t downward, the center of the disk of the disk cartridge w is placed on the disk table f, and the core provided at the center of the disk is attracted to the magnet embedded in the disk table f.
Thus, the disk is mounted on the disk table f. When the disc is attracted to the magnet of the disc table f, the holder t is locked by a holder lock mechanism (not shown).

Simultaneously, the downward movement of the lid c causes the lock piece q to move downward from the state shown by the two-dot chain line in FIG. 9 and the lock portion s of the lock piece q to tilt the engagement member j. The engaging member j slides against the edge m and moves in the direction A2 shown in FIGS. 8 and 9 against the urging force of the spring member (the state of the engaging member j shown by the two-dot chain line in FIG. 9). When the lock portion s of the lock piece q reaches the lower end of the engagement portion 1 of the engagement member j, the engagement member j is returned in the direction A1 by the spring member,
As a result, the engaging portion 1 of the engaging member j and the locking portion s of the locking piece q are engaged (the state of the engaging member j and the locking piece q shown by a solid line in FIG. 9), and the lid c is locked at the closed position. (Fig. 10
reference).

The ejecting operation of the disk cartridge w will be described below (see FIGS. 10 to 12).

As shown in FIG. 10, the finger x is applied to the slide knob n, and the slide knob n is moved to the position A shown in FIG. 8 and FIG.
Slide in two directions. When the slide knob n is slid in the direction A2, the engagement member j is moved in the direction A2, the engagement between the engagement member j and the lock piece q is released, and the lid c
Is rotated substantially upward with respect to the holder t by the spring force of the leaf spring member v. When the lid c is rotated by a predetermined angle, the lid c and the holder t are separated by a predetermined distance and connected by the above-mentioned connecting mechanism, and the upward movement of the lid c is restricted here. (See FIG. 11). At this time, the holder t is not rotated since it is locked by the holder lock mechanism, and the disk remains mounted on the disk table f.

When the lid c is moved upward, a gap y is formed between the front of the lid c and the front of the lower case d. Then, the finger x is inserted into the gap y to reach the lower edge of the front surface of the lid c, and the lid c is further rotated substantially upward.

When the lid c is further rotated upward, the lock of the holder t by the holder lock mechanism is released, and the holder t is rotated upward integrally with the lid c, so that the disk can be transferred to the disk table f. The attachment is released. At this time, the disc cartridge w locked in the holder t by the cartridge lock mechanism is unlocked, and the disc cartridge w is ejected to the outside by a return spring (not shown) (see FIG. 12).

[0019]

However, in the above-described conventional disk recording or reproducing apparatus a, when the disk cartridge w is ejected, the finger x must be moved to the cover c.
The finger x is positioned in the gap y formed between the front surface of the lid c and the front surface of the lower case d (see FIG. 12). Therefore, as shown in FIG. 12, there is a problem that the front surface of the disc cartridge w to be ejected comes into contact with the finger x and the usability is poor.

Further, the finger x addressed to the lower edge of the lid c must be once removed from the lid c, and the newly ejected disk cartridge w must be grasped and pulled out from the holder t. There is also a problem that it is troublesome to take out.

Further, in order to remove the disk cartridge w, the slide knob n is slid with the finger x, the lid c is opened with the finger x, and the discharged disk cartridge w is gripped with the finger x. Since the user has to pull the disk cartridge w out of the holder t, there is also a problem that the operation performed with the finger x is large and it takes a lot of time to take out the disk cartridge w.

Therefore, the recording medium ejecting mechanism of the present invention and a recording or reproducing apparatus using the same overcome the above-mentioned problems, facilitate the ejecting operation of the recording medium, and improve the usability of the recording or reproducing apparatus. The task is to achieve this.
