DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is, for example, provided in a storage section such as a stocker capable of storing a plurality of cartridges containing a disk, sucking a cartridge carried from a recording / reproducing section of the disk into the storage section, and The present invention relates to a cartridge suction and discharge mechanism for discharging a cartridge stored in a storage unit to a recording / reproducing unit.

[0002]

2. Description of the Related Art In recent years, various disk devices for recording and reproducing data on and from a recording medium such as a disk have become widespread. In particular, a disk device provided with a stocker capable of storing a plurality of disks in a multilayer structure is convenient because it is not necessary to exchange disks one by one. Such a disk device is provided with a transport unit having transport rollers and the like, and the transport unit performs disk transport between a stocker and a turntable (recording / reproducing unit of a disk). However, this stocker is box-shaped,
Since several partitions are provided inside it and a space for storing the disc is provided between the partitions,
The transport roller of the transport section cannot enter the inside of the stocker. Therefore, it is difficult to pull out the disk from the interior of the stocker only by the transport rollers, or to completely store the disk in the stocker only by the transport rollers.

[0003] Conventionally, such a stocker is provided with a discharge mechanism for discharging the disc stored in the stocker and a suction mechanism for drawing the disc conveyed from the turntable into the stocker. These discharge and suction mechanisms ensure that the disc is sent out to the transport section and that the disc is stored in the stocker. An example in which such a conventional discharge mechanism and suction mechanism are provided in a disk device will be described below with reference to the drawings. Note that the upper part in the drawing is the rear, and the lower part in the drawing is the front.

First, the discharge mechanism will be described. That is,
As shown in FIG. 11, a box-shaped stocker 1 and a transport unit 2 are provided inside a chassis 6 of a disk drive. First, the stocker 1 has several partitions 1 inside.
a are arranged in a multi-layered manner, and a gap is provided between the partition plates 1a to allow the disk 7 to enter. A lever 5 is provided on the left rear side of the partition plate 1a. The lever 5 is an elongated small plate, and is rotatably provided around a central portion thereof. And the right end 5a of the lever 5
Is in contact with the rear of the disk 7 stored in the stocker. Also, the left end 5b of the lever 5
Are exposed from the left side of the stocker 1.

On the other hand, the transport section 2 is provided in front of the stocker 1 and can move back and forth. The transport unit 2 is provided with a transport roller 2a for transporting the disk 7 and an operation plate 2b for pressing the lever 5, and can be moved back and forth together with the transport unit 2. The operation plate 2 b is a plate extending along the left side surface of the stocker 1, and its tip 2 c is a left end 5 b of the lever 5.
Facing each other.

Next, the suction mechanism will be described. That is, as shown in FIG. 12, a suction mechanism is provided inside each partition plate 1a of the stocker 1. The suction mechanism includes two elongated arms 3 extending in the front-rear direction and two coil springs 4 for urging the arms 3 inward. First, the arm 3 is provided on the left and right of the partition plate 1a with the shaft 3a.
Is provided so as to be rotatable around the center. The shaft 3a is provided at the rear end of the arm 3a and is located behind the stocker 1. Further, a pin 3b protruding downward is provided at the front end of the arm 3. One end of a coil spring 4 is engaged with the inside of the two arms 3.
The opposite end of the coil spring 4 is engaged with the rear center of the partition plate 1a, and urges the arm 3 inward.

The operation of the above conventional example is as follows. First, the disk suction operation will be described. That is,
Before the disk is inserted, the arms 3 are urged inward by the coil springs 4, so that the front ends of the two arms 3 are closed inward. Next, the transport unit 2
Is inserted, the edge of the disk 2 hits the pin 3b.
Then, as the disk 2 advances toward the back of the stocker 1, the pin 3b is opened outward along the circumference of the disk 2, and the coil spring 4 extends. Further, as the insertion of the disk 2 proceeds, the pin 3b moves over a half circumference of the disk 2. Then, the pin 3 b closes inward along the circumference of the disk 2 by the urging force of the coil spring 4. Therefore, the disk 2 is stored inside the stocker 1.

Next, the disc ejection operation will be described. That is, the disk 7 is stored in the stocker 1.
Then, the transport unit 2 is moved closer to the stocker 1. Then
The tip 2c of the operation plate 2b is the left end 5b of the lever 5.
Press backward. Since the lever 5 is rotatable about its central portion, when the left end 5b is pressed backward, the right end 5a rotates forward. Since the right end 5a is in contact with the rear of the disk 7, the disk 7 is pushed forward. The extruded disk 7 is transported by the transport roller 2a.

[0009]

However, the above-described discharge mechanism and suction mechanism have the following problems. That is, a disk with a built-in cartridge, such as a floppy disk or a mini disk, which has become extremely popular recently, is somewhat thicker than a normal disk. Therefore, in a device that handles a disk with a built-in cartridge, if the above-described suction mechanism is provided on the partition plate 1a in the stocker 1, the thickness of the stocker 1 increases, which is disadvantageous in downsizing the device.

Further, since the cartridge is usually in the shape of a case, a suction operation using the above-described circumference of the disk 2 cannot smoothly perform the suction operation. Then, it takes a long time to urge the disk 2 backward by the transport roller 2 in order to operate the suction mechanism, and the driving force required for the transport roller 2 is high.

Further, since the discharge mechanism only moves the disk 7 by rotating the lever 5, its discharge force is weak and its discharge stroke is short. Therefore, in order to reliably send out the disk 7 to the roller 2 and eliminate ejection errors, it is necessary to keep the position of the transport roller 2 close to the stocker 1. However, the transport roller 2 must be moved up and down to select the disk 7 stored in the desired partition plate 1a. Therefore, when the transport roller 2 and the stocker 1 are close to each other, the transport roller 2 moves to the stocker 1. There is a possibility of contact.

To address these problems, Japanese Utility Model Application No.
A cartridge ejection mechanism as shown in Japanese Patent Application No. 82016 and a cartridge suction mechanism as shown in Japanese Utility Model Application No. Hei 4-82017 have been proposed. These mechanisms reduce the thickness of the stocker in the vertical direction by arranging a suction mechanism and a discharge mechanism on the left and right sides of a cartridge stored in the stocker. According to such a mechanism, a predetermined suction member is engaged with the groove provided on the side surface of the cartridge, and the suction member is moved in the storage direction, whereby the suction operation of the cartridge into the stocker can be performed. It becomes possible. In these conventional examples, a torsion coil spring is used in order to obtain an urging force for moving the suction member. However, by providing this torsion coil spring in a reversible manner, the urging force of the discharging operation of the cartridge is reduced. You can also use it to get. Therefore, the shortage of the discharging force and the discharging stroke of the cartridge can be solved.
The roller can be provided at an appropriate position so as not to hit the stocker.

However, according to the above conventional example,
The following problems remain. That is, since the suction mechanism and the discharge mechanism are separately provided in the stocker, the space efficiency is low.

Since the cartridge moves in the stocker in the front-rear direction, it is necessary to provide a certain clearance on the left and right sides of the cartridge. Further, since there is a slight difference in the size of the cartridge depending on the product, a fixed clearance may be generated on the left and right. Such a clearance causes the cartridge in the stocker to play. To address this,
It is conceivable to provide a member for biasing the cartridge to one of the left and right sides in the stocker. However, when the cartridge is moved to one of the left and right sides, the clearance on the opposite side is enlarged, and the Japanese Patent Application No. 4-82 provided on the left and right sides of the stocker.
016 cartridge discharge mechanism or Japanese Utility Model Application No. 4-820
Since it is separated from one of the cartridge suction mechanisms 17, a malfunction easily occurs.

The lever 5 for pressing the disk 7 in the discharging mechanism directly contacts the disk 7, but in the cartridge discharging mechanism of Japanese Patent Application No. 4-82016, similarly, the lever plate for discharging the cartridge is directly connected to the cartridge. The abutment may damage the edge of the cartridge.

The present invention has been proposed in order to solve such problems of the prior art, and an object of the present invention is to provide a cartridge suction / discharge mechanism capable of performing a space-efficient, smooth and stable suction / discharge operation. It is to be.
