Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to file a large amount of information such as literary information, video information, audio information, etc. using a large number of disks as record carriers, and This invention relates to a disk file device that can selectively pull out a large number of disks at high speed so that the information on the capacity can be read out at high speed, and supply the information to a player that reads the information. .

[Background technology and its problems]

One known example is JP-A-5'9-30263, for example. In this case, a plurality of thin cartridges containing Guinuku are stored vertically and parallel to each other in the horizontal direction.

The stocker is configured to be movable in the horizontal direction, a pull-out mechanism having a pair of upper and lower pull-out claws disposed in front of the stocker, and a player placed beside the pull-out mechanism. By moving the stocker in the horizontal direction, a designated cartridge from among the plurality of cartridges stored in the stocker is transferred to the front position of the pull-out mechanism.

After the stocker has stopped, the pull-out mechanism is operated to selectively pull out the designated cartridge to the front of the stocker using the pair of pull-out claws. Then feed the cartridge you pulled out to the player.

It is configured to perform recording and playback on the disc in the cartridge.

However, this known example cannot be provided with a cartridge reversing device that rotates the cartridge pulled out from the stocker by 80 degrees and supplies it to the player. Therefore, in this known example, only one single-sided disc can be used, and it is completely impossible to use a double-sided disc and record and play back on both sides of the disc while freely reversing sides A and B of the cartridge. There was a flaw in that the amount of information in the file was limited.

[Purpose of the invention]

The present invention enables the carrier to be provided with a cartridge reversing mechanism so that sides A and B of the cartridge pulled out from the stocker can be freely reversed and supplied to the player. 1
The reversing mechanism is made as small as possible to prevent the carrier from increasing in size due to the provision of the reversing mechanism, and the reversing mechanism is supported extremely stably to prevent the reversing mechanism from wobbling while the cartridge is being transferred by the carrier. This is to prevent this from happening.

[Summary of the invention]

The present invention relates to a stocker in which a number of thin cartridges each containing discs are housed in parallel in a number of storage shelves, a player for writing and reading information to and from the discs in each cartridge, and a stocker. The cartridge is selectively pulled out from the cartridge and is transported to the player. In addition, a cartridge holding portion is provided on the other side, and the pair of support shafts are arranged on the same axis parallel to the cartridge loading/unloading direction at a central position in the width direction of the reversing plate and spaced apart from each other in the cartridge loading/unloading direction. The reversing plate is pivotally supported to the frame by these pair of support shafts so as to be rotatable by 180 degrees, and a motor is disposed on the same axis between these pair of support shafts, and one of the support shafts is rotationally driven by the motor. With the cartridge drawn out from the stocker being held in the cartridge holding part of the reversing plate, the reversing plate is rotated 180 degrees by a motor while the cartridge is being transferred to the player by the carrier, so that the A of the cartridge is ◇ According to the present invention configured in this way, the A and B sides of the cartridge pulled out from the stocker can be freely arranged between a pair of spindles. As a result, the motor is accommodated within the projected area of the reversing plate.

There is no possibility that the motor will protrude outward from the side of the reversing plate. Therefore, the reversing mechanism can be made as small as possible, and it is possible to prevent the carrier from increasing in size due to the provision of the reversing mechanism. Furthermore, since the reversing plate is likely to be supported on a cantilever because cartridges are inserted and removed from one end thereof, a pair of support shafts are provided on one side of the reversing plate, and a cartridge holding portion is provided on the other side.

By arranging the pair of support shafts at a distance in the cartridge loading/unloading direction, it was possible to support and rotate the single reversal plate on both sides. Therefore, the reversing mechanism is supported extremely stably, and there is no wobbling of the reversing plate in the reversing mechanism during transport of the cartridge by the carrier.
