Abstract

PURPOSE:To improve operability of inserting a cartridge into a magnetooptic disk device. CONSTITUTION:When a cartridge 1 is inserted from an opening 2a of a cassette holder 2 and inserted to a predetermined position, a protrusion 9a of a lock lever 9 mounted at a slide holder 8 is engaged with a recess 1d of the cartridge 1, held by the holder 8, which starts moving in an inserting direction of the cartridge 1. When the holder 8 is moved to a predetermined position of the holder 2, connection of a pin 18 with a groove 5b of a holder arm 5 is disconnected, the movement of the holder 8 is ended, and the position is held by a spring 7 provided at an arm 4. The holder 2 is moved perpendicularly to the inserting direction of the cartridge 1 along a groove 15a of the side due to the movement of a loading plate 15 to mount the cartridge 1 at a predetermined position.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magneto-optical disk cartridge mounting device.

0002

[Prior Art] In a conventional magneto-optical disk cartridge mounting device, when mounting a cartridge, the cartridge is inserted through a cartridge insertion opening provided in a part of a cassette holder that houses the cartridge, and the rear end of the cartridge is pressed with a fingertip. is inserted, and the cartridge is inserted while opening the shutter of the cartridge using the shutter arm built into the cassette holder. When the cartridge is inserted into the magneto-optical disk device just above the insertion position, the lock lever built into the cassette holder opens. At the same time, the elevating mechanism operates to lower the cassette holder and mount the cartridge at a predetermined position in the magneto-optical disk device. When ejecting the cartridge, the cassette holder rises when the lifting mechanism operates, and when the cassette holder rises to the cartridge ejection position, the lock lever is opened and the cartridge is released from the cassette holder, and the shutter arm receives a return force in the cartridge ejection direction. The cartridge is provided with a mechanism in which the cartridge is moved in the ejection direction by the reciprocating force of the shutter arm, and the ejection operation is completed when the shutter of the cartridge is closed.

0003

[Problems to be Solved by the Invention] In the above-described conventional magneto-optical disk cartridge loading device, when inserting a cartridge, the rear end of the cartridge is inserted into the magneto-optical disk device through the cartridge insertion slot provided on the front surface of the magneto-optical disk device. It is difficult to push the cartridge in because the cartridge insertion opening is narrow, and there is a risk that the fingertip may get caught in the gap between the rear end of the cartridge and the front wall of the magneto-optical disk drive when the cartridge is lowered. There are drawbacks.

Furthermore, when the cartridge is ejected, since there is no mechanism to regulate the amount of cartridge ejected, the cartridge is pushed out by the reciprocal force of the shutter arm, and the ejected amount is affected by variations in the reciprocal force and the friction between the cartridge and the cassette holder. There are disadvantages in that the product image is damaged due to the inconsistency, and in the worst case, there is a risk that the cartridge will jump out of the cassette holder and fall out of the magneto-optical disk device.

(b) is a diagram showing the state before the cartridge is inserted, and (b) is a diagram showing the state after the cartridge is inserted.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 and 2.
Explain using.

As shown in FIG. 2(a), the cartridge 1
is inserted through the opening 2a of the cassette holder 2 to a predetermined position, the protrusion 9a of the lock lever 9 attached to the slide holder 8 fits into the recess 1d of the cartridge 1, and the cartridge is held in the slide holder 8. Ru. Then, the drive motor 17 started to rotate and the reduction gear 18 rotated, and the pin 19 rotated the holder arm 5, so that the holder arm 4, which formed a link mechanism on the holder arm 5, rotated and was connected to the holder arm 4. Slide holder 8
starts moving in the insertion direction of the cartridge 1.

When the cartridge 1 held by the slide holder 8 moves together with the slide holder 8, the tip of the shutter arm 3 touches the shutter 1c of the cartridge 1.
As the cartridge 1 moves further, the shutter 1c opens as the shutter arm 3 rotates, releasing the access hole 1b. When the slide holder 8 moves to a predetermined position on the cassette holder 2, the connection between the pin 18 and the groove 5b of the holder arm 5 is released, and the movement of the slide holder 8 is completed.
The position is held by a spring 7 attached to the holder arm 4. However, the reduction gear 18 continues to rotate and the pin 19
Next, the loading plate 15, which is connected to the notch 15b of the loading plate 15 and held in position by the urging force of the spring 16, starts to move in the insertion direction of the cartridge 1 due to the rotation of the reduction gear 18. The cassette holder 2 moves perpendicularly to the insertion direction of the cartridge 1 along the side groove 15a by the movement of the loading plate 15, and mounts the cartridge 1 in a predetermined position. When the cassette holder 2 moves, the center part of the coil connecting rod 13 moves together with the cassette holder 2, and the end 7b of the connecting rod 7 fits into the groove 14b of the base 14.
remains in its original position, the connecting rod 7 rotates around the fulcrum 2d of the cassette holder 2, and the end 7a of the connecting rod 7 moves in the same direction as the moving direction of the cassette holder 2, The coil base 6 fitted to the coil base 7a is moved, and the bias magnetic field coil 10 attached to the coil base 6 is mounted in a predetermined position.

When the cartridge 1 is ejected, the drive motor 16 is rotated in the opposite direction to that when it was inserted, and the cartridge 1 is ejected in the reverse order described above, and the shutter 1c of the cartridge 1 is closed. At this point, the cartridge 1 is held in the slide holder 8 by the lock lever 9, and the ejection operation ends.

Even if the shutter arm 3 is rotatably attached to the slide holder 8, the act of manually inserting and releasing the shutter 1c of the cartridge 1 only increases, and the operation of moving the cartridge 1 in the insertion and ejection direction is not affected. .

[0021]

As explained above, the present invention adds a slide holder that can reciprocate in the cartridge insertion/ejection direction to a cassette holder for storing a cartridge, and a link mechanism for driving the slide holder, so that the cartridge can be inserted into the cassette holder. By adding the function of moving in the ejection direction, when inserting a cartridge, there is no need to insert the cartridge from the cartridge insertion slot of the magneto-optical disk device to just above the mounting position of the magneto-optical disk device. Operability is improved because there is no need to insert the cartridge into the magneto-optical disk device through the cartridge insertion slot of the disk device, and when ejecting the cartridge, the built-in lock lever holds the cartridge and removes it from the magneto-optical disk device. Since the cartridge is ejected, the amount of cartridge ejection is constant, and
This has the advantage that the danger of the cartridge falling out of the magneto-optical disk device can also be avoided.
