The present invention relates to a disc file device capable of selectively drawing out a large number of discs at high speed so that the information can be read out at high speed and supplying it to a player for writing and reading information.

[Background technology and its problems]

As a known example, there is JP-A-59-30263. In this known example, a plurality of thin cartridge ridges each having a disk accommodated therein are stored in parallel in the horizontal direction in a vertically standing state, and a stocker configured to be movable in the horizontal direction, It is composed of a drawer mechanism having a pair of upper and lower drawer claws arranged on the front surface, and a player arranged beside the drawer mechanism. Then, by moving the stocker horizontally, the designated cartridge out of the plurality of cartridges stored in the stocker is transferred to the front position of the drawer mechanism, and after the stocker is stopped, the drawer mechanism is operated to operate the pair of drawers. The pawl selectively pulls out the specified cartridge in front of the stocker. Then, the cartridge cartridge that has been pulled out is supplied to the player to record and reproduce the disk in the cartridge.

However, this known example has a structure in which a cartridge inverting device for rotating a cartridge extracted from a stocker by 180 ° and supplying it to a player cannot be provided. Therefore, in this known example, only a single-sided disk can be used, and it is completely possible to record and reproduce on both sides of the disk while freely reversing the A and B sides of the cartridge using a double-sided disk. Since it cannot be done, there was a defect that the amount of information file was limited.

[Object of the Invention]

According to the present invention, by providing the carrier with a cartridge reversing mechanism, it is possible to freely reverse the A and B surfaces of the cartridge which is pulled out from the stocker and supply it to the player. that time,
The reversing mechanism is made as small as possible to prevent the carrier from becoming large due to the provision of the reversing mechanism, and the reversing mechanism is supported very stably, and the reversing mechanism rattles while the cartridge is being transferred by the carrier. It is something that does not happen.

[Outline of Invention]

The present invention relates to a stocker in which a large number of thin cartridges each having a disk stored therein are stored in parallel in a large number of storage shelves, a player for writing and reading information on the disks in each cartridge, and the above stocker. In a disk file device having a carrier for selectively feeding a cartridge that has been drawn from the cartridge and supplying the cartridge to the player, one side of a reversing plate provided in the frame of the carrier overlaps the reversing plate. As described above, a pair of support shafts are provided, and a cartridge holding portion is provided on the other side surface, and the pair of support shafts are parallel to the cartridge loading / unloading direction at the center position in the width direction of the reversing plate. Are arranged on the same axis at a distance in the direction of insertion and removal, and the pair of support shafts causes the reversal plate to move to the frame. A motor that is rotatably supported by 180 ° and that is arranged between the pair of support shafts so as to overlap the inversion plate is configured to rotate and drive one support shaft. While the cartridge pulled out from the stocker is transferred to the player by the carrier while being held in the cartridge holding portion of the reversing plate, the reversing plate is moved by the motor.
This is a disk file device configured so that the A and B surfaces of this cartridge can be reversed by rotating it by 80 °.

According to the present invention having such a configuration, it is possible to freely reverse the A and B surfaces of the cartridge ledge pulled out from the stocker and supply it to the player. Moreover, at that time, since the motor that drives the reversing plate to rotate 180 ° is arranged between the pair of support shafts, the motor is housed within the projected area of the reversing plate, and the motor is placed outside the reversing plate. There is no such thing as a large protrusion to one side. Therefore, the reversing mechanism can be miniaturized as much as possible, and it is possible to prevent the carrier from becoming large due to the provision of the reversing mechanism. Also, the reversing plate tends to be cantilevered in relation to take in and out the cartridge ledge from one end side, but a pair of support shafts is provided on one side surface of the reversing plate and a cartridge ridge holding portion is provided on the other side surface, and By arranging the pair of support shafts at a distance in the direction of inserting and removing the cartridge, it was possible to support the reversal plate on both sides. Therefore, the reversing mechanism is supported extremely stably, and there is no rattling of the reversing plate in the reversing mechanism during the carriage of the cartridge by the carrier.
