Description

[Detailed explanation of the invention] [Industrial application field] The present invention is a method for storing large-capacity information such as document information, video information, and audio information using a large number of disks as record carriers. This invention relates to a disk file device that can selectively pull out a large number of disks at high speed so that information can be read out at high speed and supplied to a player that writes and reads information.

[Background technology and its problems]

As a known example, there is, for example, Japanese Utility Model Application Publication No. 59-25674. This known example consists of an oblong horizontal stocker in which multiple thin cartridges with disks stored inside are stored vertically and parallel to each other, and the stocker is placed in front of the stocker. It consists of a pull-out mechanism having a pair of upper and lower pull-out claws, and a player placed next to the pull-out mechanism. By moving the stocker in the horizontal direction, the tips of the pair of pull-out claws are relatively moved within the pair of pull-out claw engagement grooves provided on both upper and lower sides of one end of the cartridge.
The tips of the pair of pull-out claws are positioned within the pair of pull-out claw engagement grooves of the cartridge designated to be pulled out. After this horizontally transferred stocker is stopped at a designated position, the pull-out mechanism is operated to selectively pull out the designated cartridge to the front of the stocker using a pair of pull-out claws. The drawn cartridge is then supplied to a player to perform recording and playback on the disc in the cartridge.

However, in this known example, by horizontally transporting the stocker, a specified cartridge in the stocker can be approached (accessed) to the player.
Because of this, the cartridge stored in the stocker tends to fly out in front of the stocker due to vibrations during transport or when the stocker is stopped, and the position of each pair of pull-out pawl engagement grooves may be significantly misaligned. Easy to occur. If misalignment occurs in each pair of pull-out pawl engagement grooves, the tips of the pair of pull-out pawls cannot move safely within these pair of pull-out pawl engagement grooves when the stocker is horizontally transferred, and the pair The tip of the pull-out claw collides with the cartridge. Therefore, especially in this known example, the cartridge is carefully positioned within the stocker,
A positioning device must be provided to prevent the cartridge from shifting due to vibrations during transport or when the stocker is stopped.

For this reason, in this known example, each pair of positioning rollers is attached to the side surface of each cartridge storage shelf of the stocker by a leaf spring, and each pair of positioning rollers is installed in a pair of positioning grooves provided on one side of each cartridge. A positioning device was provided which positions each cartridge by engaging the positioning rollers with each other by the spring force of a leaf spring.

However, this known positioning device
It is necessary to provide twice the number of positioning rollers and grooves as the number of cartridges stored in the stocker, and the same number of leaf springs as the number of cartridges, making the structure very complicated and requiring a large number of parts and assembly man-hours. This results in significantly higher costs. In addition, the insertion and withdrawal of the cartridge from the stocker must be performed against each pair of positioning rollers, and a large amount of force is required for the insertion and withdrawal, and a large motor is required to drive the pair of withdrawal claws. must be used.

[Purpose of invention]

The present invention was devised to correct the above-mentioned deficiencies, and is capable of simultaneously positioning a large number of cartridges stored in a stocker with one positioning member, and also allows for the simultaneous positioning of a large number of cartridges stored in a stocker. This also allows for easy insertion operations.

[Summary of the idea]

The present invention consists of a stocker in which a number of thin cartridges each containing disks are stored in parallel in a number of storage shelves, a player that writes information to and reads information from the disks in each cartridge, and a stocker.

The tips of the pair of pull-out claws are positioned in the pair of pull-out claw engagement grooves of the cartridge, and the drawer claws are arranged on the side surface of the stocker parallel to the transport direction of the carrier and over substantially the entire length of the stocker. The provided long positioning member is disposed, and this positioning member is rotatably supported on the side surface of the stocker by a rotating member, so that the positioning member can be moved in and out of the stocker, and the positioning member is configured to be able to move in and out of the stocker. After the cartridges are inserted into each of the storage shelves, the positioning member is moved into the stocker by a spring to position them in the positioning grooves provided on each side of the numerous cartridges stored in the stocker. The members are engaged simultaneously to simultaneously position the plurality of cartridges so that the tips of the pair of pullout claws are positioned approximately at the center of the groove width of the pair of pullout claw engaging grooves of the plurality of cartridges. This is a disk file device configured as follows.

According to the present invention constructed in this manner, a large number of cartridges housed in the stocker can be simultaneously positioned with one positioning member. Furthermore, after the cartridge is inserted into each storage shelf of the stocker, the positioning member is engaged with the positioning groove of the cartridge by means of a spring, so when each cartridge is inserted into the stocker, the positioning member is engaged with the positioning groove of the cartridge.

The cartridge 1 and both pull-out claws 12 are moved in the direction of the arrow Y without being brought into contact with the cartridge 1 in the grooves 11 for engaging the pull-out claws. It is structured so that it does not get in the way.

Next, a series of operations related to high-speed reading of information in this disk file device based on the above configuration will be explained with reference to FIG.

First, the tips 12a of both pull-out claws 12 of the carrier 6
The position indicates the position where the cartridge 1 is supplied to the upper player 4, while the used cartridge 1 from which information has already been read is ejected from the lower player 5.

Next, transfer cartridge 1 to player 4 at the top.
After the carrier 6 is fed, the carrier 6 is vertically moved in the Ya direction, and the tips 12a of both pull-out claws 12 are moved from the position to be engaged in the pull-out claw engaging grooves 11 of the used cartridge 1 of the lower player 5. .

Note that after the tips 12a of both pull-out claws 12 have moved from the position to the upper player 4, the supplied cartridge 1 is pulled into the player 4, and data is written on the disk in the cartridge 1. Information is read.
While the information is being read, the used cartridge 1 of the lower player 5 is returned to the original storage shelf 3 of the stocker 2, and then access is made to the cartridge 1 to be pulled out next, and the cartridge 1 is pulled out. A series of preparatory operations for continuous reading of information, such as , transport, and standby for supply to the player 5 below, are performed at high speed.

That is, first, both pull-out claws 12 of the carrier 6 are horizontally transferred in the Xa direction and pulled in from the position, and the used cartridge 1 of the lower player 5 is hooked by the tips 12a of both pull-out claws 12, and the carrier 6 is pulled out. 6 (actually, inside the cartridge holding section provided on the reversing plate 18).

Next, the carrier 6 is vertically transferred in the Yb direction to the stocker 2 to which the used cartridge 1 is to be returned.
After being moved to the height position of the original storage shelf 3 and stopped, both pull-out claws 12 are moved horizontally in the Xb direction and pushed out from the position, and the tips 12a of both pull-out claws 12 remove the used cartridge 1 is pushed back from the carrier 6 into the original storage shelf 3 of the stocker 2 and stored therein.

Next, the carrier 6 is vertically transferred (in the Ya direction) to a position opposite to the cartridge 1 to be pulled out next. It is vertically transferred along the inside of the groove 11 for engaging both pull-out claws.

Then, after the carrier 6 approaches (accesses) the designated cartridge 1 and is stopped, both pull-out claws 1
2 is horizontally transferred in the Xa direction and pulled in from the position, and the tips 12a of both pull-out claws 12
The designated cartridge 1 is hooked and pulled out from the storage shelf 3 of the stocker 2 into the carrier 6.

Next, the carrier 6 is vertically moved in the Ya direction to a position at the height of the lower player 5 and stopped, and then both pull-out claws 12 are moved horizontally in the Xb direction and pushed out from the position. The specified cartridge 1 is supplied from the carrier 6 to the player 5 at the lower portion by the tips 12a of both pull-out claws 12.

As a result of the above, a series of preparatory operations are performed at high speed,
When the upper player 4 finishes reading the information and the used cartridge 1 is ejected, the carrier 6 is vertically moved in the Yb direction, and the tips 12a of both pull-out claws 12 move from the position to the upper player 4. is engaged in both pull-out pawl engagement grooves 11 of the used cartridge 1.

As explained in FIG. 1, when the carrier 6 is vertically transferred in the direction of the arrow Y and approaches (accesses) the cartridge 1 in the stocker 2 to be pulled out next, both pull-out claws 12 of the carrier 6 are moved. Tip 12
a is safely vertically transferred approximately at the center of the groove width W of the grooves 11 for engaging the pull-out claws of all the cartridges 1 in the stocker 2, and the tips 12a of both pull-out claws 12 are accidentally moved into the cartridge 1. There is no chance of any collisions.

Note that the carrier 6 is connected to a predetermined cartridge 1.
When the two drawer claws 12 pull out the specified cartridge 1 in the direction of arrow Xa in FIG. 6 after approaching (accessing) the cartridge, the motor 33 is first rotated in the direction of arrow c in FIG. , the positioning member 22 is pulled out of the stocker 2 via the rotating member 23 in the direction of arrow b, as indicated by the dashed line in FIG. Thereafter, the pull-out pawl transfer means is driven by the motor 15, and the cartridge 1 is pulled out by both the pull-out pawls 12 in the direction of arrow Xa in FIG. At this time, when the positioning member 22 is pulled out of the stocker 2, the positioning state of the cartridge 1 inside the stocker 2 is released, but as shown in FIG. Each temporary fixing member 43 has a weak spring 44 in the temporary fixing groove 41.
Since each cartridge 1 is temporarily fixed in each storage shelf 3, each cartridge 1 will not fly greatly toward the front side 2a of the stocker 2 due to vibration or the like. I won't release it.
