As shown in FIGS. 8 and 10, the arm portion 27 of the engaging member 24 is bent vertically downward, and then horizontally bent forward below the cartridge holder 3. Has an engagement pin 28 implanted therein.

Next, the loading operation and the ejecting operation of the disk cartridge in the conventional example configured as described above will be described.

First, as shown in FIGS. 6 and 8, the disk cartridge 30 is manually inserted by hand to the insertion position in the cartridge holder 3 in the direction of arrow f. In addition,
The disk cartridge 30 is composed of a disk (micro floppy disk) 30a and a thin case 3 made of synthetic resin.
0b so as to be freely rotatable. When the disc cartridge 30 is inserted, the engaging member 24 is once rotated in the direction of arrow e 'by the front end of the disc cartridge 30 against the return spring 26, as shown by the dashed line in FIG. When the insertion member 30 is inserted to the insertion position, the engagement member 24 is rotated by the return spring 26 in the direction of arrow e as shown by the solid line, and the engagement pin 28
Are engaged in the semicircular engaged portion 31 provided on the lower surface of the case 30b of the disk cartridge 30.
The rotation of the engagement member 24 in the direction of the arrow e 'is released by the notch 32 formed in the side portion 3a of the cartridge holder 3. Also, as shown in FIG.
The shutter 33 is slidably attached to the disk cartridge 30 by the opening / closing pin 15 by being pressed and rotated in the direction of arrow c ′ against the return spring 14.
Is slightly opened in the direction of arrow g.

Next, when the disc cartridge 30 is slightly pressed in the direction of arrow f by hand from the insertion position, the shutter opening / closing lever 12 is further rotated in the direction of arrow c ',
The protrusion 35 of the lock lever 16 engaged in the notch 34 of the shutter opening / closing lever 12 is driven, and the lock lever 16 is rotated in the direction of arrow c 'as shown in FIG. At this moment, the lock pin 18 of the lock lever 16 is disengaged from the locked portion 19 of the elevating operation plate 2 and the lock is released. Then, the drive lever 7 is rotated in the direction of the arrow b by the drive spring 9, and the draw-in plate 20 moves forward in the direction of the arrow d via the pin 23. Due to the forward movement of the retracting plate 20, the disc cartridge 30 is retracted from the insertion position in the cartridge holder 3 to the retracted position in the direction of the arrow f via the engaging member 24. Further, when the drive lever 7 is rotated in the direction of arrow b, the pressed portion 11 of the elevating operation plate 2 is pressed by the pin 10 and the elevating operation plate 2 is slid in the direction of arrow a. As a result, each roller 4 of the cartridge holder 3 is guided downward by a pair of front and rear inclined guides 36 formed on the upper edges of both sides 2a of the lifting operation plate 2, and the cartridge holder 3 is moved from the raised position in FIG. 9 is lowered to the lower position. by this,
The disk 30a of the disk cartridge 30 is mounted horizontally on a turntable 37 on the chassis 1, and
As shown in FIG. 7, a recording / reproducing head (not shown) is inserted into a head insertion hole 38 which is completely opened by a shutter 33 which is completely opened. Thus, the disk cartridge 30 is automatically loaded by the spring force of the drive spring 9.

Next, when an eject signal is output after desired recording / reproduction, a drive gear 40 is driven to rotate by a motor 39 disposed at the rear end of the chassis 1, and an eccentric roller provided on the drive gear 40 is provided. Lifting operation plate 2 by 41
Is pulled and slid in the direction of arrow a '. Then, each roller 4 is guided by the inclined guide 36 of the elevating operation plate 2, and the cartridge holder 3 is moved from the lowered position in FIG.
To the ascent position. Also, an arrow a 'of the lifting operation plate 2
When sliding in the direction, the pressed lever 11
Is pushed, and the drive lever 7 is rotated in the direction of arrow b '. Then, as shown in FIGS. 7 to 6, the retracting plate 20 is moved back in the direction of the arrow d ′ via the pin 23 of the drive lever 7, and the disc cartridge 30 is retracted into the cartridge holder 3 via the engaging member 24. To the insertion position in the direction of arrow f '. When the disc cartridge 30 is pushed out, the lock lever 16 is rotated in the direction of arrow c by the return spring 14, and the lock pin 18 is engaged with the locked portion 19 and locked. Then, after the protrusion 42 of the engagement member 24 comes into contact with the rear end of the cartridge holder 3, the retracting plate 20 moves back in the direction of the arrow d ′ in the final stage of sliding of the elevating operation plate 2. As shown by the dashed line in FIG. 10, the engaging member 24 is rotated in the direction of the arrow e ′ against the return spring 26, and the engaging pin 28 is disengaged from the engaged portion 31 of the disk cartridge 30. . Then, the shutter opening / closing lever 12 is rotated in the direction of arrow c by the return spring 14,
While the shutter 33 is closed in the direction of arrow g ', the disc cartridge 30 is further pushed out of the insertion position in the direction of arrow f' and ejected. Thus, the disk cartridge 30 is automatically ejected by the motor 39.

[0011]

In the prior art, as described above, during the loading operation, the engaging member 24 is engaged with the disk cartridge 30 inserted into the insertion position in the cartridge holder 3. After that, the lock by the lock lever 16 is released, and the disk cartridge 30 is loaded. This prevents a so-called misloading in which the cartridge holder 3 is lowered in a state where the disk cartridge 30 is not completely drawn into the cartridge holder 3 (remaining state).

However, as described above, it is necessary to previously engage the engaging member 24 with the disk cartridge 30.
Conversely, it causes a problem during the eject operation. That is, in the above-described conventional example, the return spring 26 is urged to rotate to the engagement position in the direction of arrow e so that the engagement member 24 is always engaged with the disk cartridge 30. The retracting plate 20 at the final stage causes the engaging member 24 to rotate in the direction of arrow e ', and the engaging pin 28 to be disengaged from the engaged portion 31 of the disk cartridge 30. For this reason, if the user inadvertently touches the disc cartridge 30 with his / her hand immediately before the detachment to temporarily prevent the disc cartridge 30 from being pushed out, the lifting / lowering operation plate 2 is driven by the motor 39.
Even when the disk cartridge 30 is completely slid, the engaging pin 28 of the engaging member 24 is not disengaged from the engaged portion 31 of the disk cartridge 30. As a result, the disk cartridge 30 stops at the insertion position in the cartridge holder 3. It becomes a dead point.

As described above, in the conventional example, there is a dead point that is not completely ejected during the ejecting operation, and the user determines that this is a failure of the apparatus, and forcibly pulls the disk cartridge 30 out of the cartridge holder 3. As a result, not only the disk cartridge 30 but also the internal mechanism of the apparatus is destroyed. If the disk cartridge 30 cannot be pulled out due to the dead point, there is no problem if the disk cartridge 30 is once pressed to be loaded, ejected again, and completely ejected, but the handling of the user is various. Therefore, eliminating dead points is the most effective measure.

Therefore, the present invention prevents a drawback error when pulling a disk cartridge from an insertion position in a cartridge holder to a draw position, and completely eliminates a dead point when pushing a disk cartridge from the draw position to the insertion position. That can be eliminated.

[0015]

According to the present invention, in the above-described apparatus for mounting a disc cartridge, the engaging member is rotatably mounted on the draw-in plate between a disengaged position and an engaged position. A guide portion configured to bias the mating member to rotate to the disengagement position by a return spring, and to rotate the engagement member to the engagement position against the return spring as the retracting plate moves forward. Is provided in the cartridge holder, and when the disk cartridge is pulled from the insertion position to the retracted position by the forward movement of the retracting plate, the engaging member is guided by the guide portion along with the forward movement of the retracting plate. The engagement member is rotated from the disengaged position to the engagement position against the return spring to engage the disk cartridge, and the disk cartridge is returned by the retracting plate. When pushing out from the retracted position to the inserted position, the guide member releases the rotation of the engaging member to the engaged position with the return movement of the retracting plate, thereby returning the engaging member to the return position. The disk cartridge is configured to be pivoted to a detached position by a spring and detached from the disk cartridge.
