(Figures 1 and 2) Explanation of the 180° reversal and locking operation of the G4 carrier (Figures 1 to 4) A large amount of information is stored on a large number of disks as record carriers, and information is written and read by selectively pulling out a large number of disks at high speed so that the large amount of information can be read out at high speed. This invention relates to a disk file device that can be supplied to a player that performs the following operations.

Summary of the invention The invention consists of a stocker in which a number of cartridges each containing disks are stored in parallel in a number of storage shelves, a player that writes information to and reads information from and to the disks in each cartridge;
It has a carrier that transports and supplies the cartridge selectively pulled out from the stocker to the player, and the carrier has a pair of pull-out claws for pulling out the cartridge from the stocker, and can hold the pulled-out cartridge and rotate it 180 degrees. and a cartridge holding part configured to rotate the cartridge, and while the cartridge pulled out from the stocker is held in the cartridge holding part of the carrier and transferred, the A and B sides of the cartridge are reversed by inverting the cartridge holding part 180 degrees. In the disk file device configured to obtain, when the pull-out claw of the carrier is in a position other than the retracted position where the cartridge is pulled into the cartridge holder from the stocker, the cartridge holder cannot be turned over. By providing a locking mechanism that can be locked in place, when the pull-out pawl is engaged with the cartridge to pull out the cartridge from the stocker, or during the pull-out operation of the cartridge, First, it is possible to prevent the cartridge and the pull-out claw from being damaged immediately due to the cartridge holding part being inadvertently reversed.

C. Prior Art The prior invention (Japanese Patent Application No. 116211/1989) filed earlier by the applicant of the present invention is a system in which a number of cartridges each containing a disk are stored in parallel in a number of storage shelves. It has a stocker, a player that writes information to and reads information from a disk in each cartridge, and a carrier that transports cartridges selectively pulled out from the stocker and supplies them to the player, and the carrier pulls out the cartridges from the stocker. A cartridge holder is provided with a pair of pull-out claws for holding the pulled-out cartridge and a cartridge holder configured to be able to rotate the cartridge by 180 degrees. By turning the cartridge holding part 180°, the cartridge can be
This is a disk file device configured so that the B side can be reversed.

According to this prior invention, by using a double-sided disk, it is possible to write and read information on both sides of the disk while freely reversing the A and B sides of the cartridge, thereby doubling the amount of information files on the disk. I can do it.

D Problems to be solved by the invention However, in this prior invention, due to a failure of the system control circuit, etc., the pull-out claw is engaged with the cartridge to pull it out from the stocker, or the cartridge pull-out operation is interrupted. If the cartridge holder is inadvertently reversed during the process, an accident may occur in which the cartridge or the pull-out claw is immediately damaged.

In addition, in this type of disk file device, if the power is cut off due to a power outage while the pull-out claw is engaged with the cartridge of the stocker, the pull-out claw will be inserted into the cartridge holding part when the power is turned on next time. It is preferable to return the cartridge to its original position once. However, in the prior invention,
There was a problem with the pull-out claw returning to its origin.

In other words, when issuing a home return command to the drawer claw in the above condition, if the cartridge holding part is even slightly tilted from its normal position (parallel to the storage shelf of the stocker), the drawer will not be able to be pulled out. If the nail gets caught in the cartridge, it becomes stuck and an accident occurs.

The present invention enables the cartridge holding part to be rotated 180 degrees only when the pull-out claw of the carrier is at the cartridge retracting position within the cartridge holding part.
When the pull-out claw is in a position other than the cartridge retracting position, the cartridge holding part can be locked in a non-reversible state.

E. Means for Solving the Problems The present invention provides the above-described disk file device with a locking mechanism that can lock the cartridge holding portion of the carrier in two 180° reversed positions each time, and a lock release means for unlocking the locking mechanism when the claw reaches a retracted position in which the cartridge is pulled from the stocker into the cartridge holding part; This disk file device is constructed so that the cartridge holding section is locked in a non-reversible state when the cartridge is in the position shown in FIG.

F Function The present invention provides that when the carrier pull-out claw is at the cartridge retracting position within the cartridge holder,
The lock mechanism is unlocked by the lock release means, and the cartridge holder can be rotated 180 degrees. When the pull-out claw is in a position other than the cartridge retracting position, the cartridge holding portion is locked by the locking mechanism and cannot be turned over.

G. Embodiment Hereinafter, one embodiment of the disk file device of the present invention will be described based on the drawings.

The entire G1 disk file device will be explained with reference to FIGS. 5 to 7.

Next, as shown in FIG. 5, each pair of grooves 11 in a large number of cartridges 1 stored in the stocker 2 and the cartridges 1 supplied to both players 4 and 5 are inserted in a direction parallel to the direction of arrow Y, which is the carrier transport direction. It is matched to the position on the vertical line Y′. When the carrier 6 is vertically transported linearly in the direction of arrow Y with both pull-out claws 12 pulled out to the pull-out position shown by solid lines in FIG.
inserts the inside of both grooves 11 of cartridge 1 into the cartridge 1.
The cartridge 1 and both pull-out claws 12 are constructed so that they do not interfere with the vertical movement of the carrier 6.

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 positions of both pull-out claws 12 of the carrier 6 indicate the position where the cartridge 1 is supplied to the upper player 4, and on the other hand, the used cartridge 1 from which information has already been read is ejected from the lower player 5. There is.

Next, transfer cartridge 1 to player 4 at the top.
After the supply of
It is engaged in both grooves 11 of the used cartridge 1 of the lower player 5.

Note that after 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 the information written on the disk in the cartridge 1 is read. will be held. 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 the next cartridge 1 to be pulled out is searched, pulled out, transferred, and A series of preparatory operations for continuous reading of information, such as waiting for supply to the lower player 5, 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 both pull-out claws 12 and pulled into the carrier 6 ( Actually, the cartridge is taken into the cartridge holding section (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 transferred to the height position of the original storage shelf 3 and stopped, both drawer claws 12 are moved horizontally in the 6 and is pushed back into the original storage shelf 3 of the stocker 2 and stored.

Next, the carrier 6 is vertically moved in the Ya direction to search for the next cartridge 1 to be pulled out. vertically transported along the inside.

After the carrier 6 searches for the designated cartridge 1 and is stopped, both the pull-out claws 12 are horizontally moved in the Xa direction and pulled in from the position, and the designated cartridge 1 is pulled out by the both pull-out claws 12. The carrier 6 is hung and pulled out from the storage shelf 3 of the stocker 2 into the carrier 6.Next, the carrier 6 is vertically transferred in the Ya direction to the height position of the lower player 5 and stopped, and then both drawers are pulled out. The claw 12 is horizontally transferred in the Xb direction and pushed out from the position, and the specified cartridge 1 is supplied from the carrier 6 to the lower player 5 by both pull-out claws 12.

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

Then, after both pull-out claws 12 move from the position to the lower player 5, the specified supplied cartridge 1 is pulled into the player 5, and the information written on the disk in the cartridge 1 is pulled into the lower player 5. While reading is carried out, the carrier 6 which has returned to the upper player 4 repeats a series of preparatory operations similar to those described above at high speed.

By the way, this disk file device can use a double-sided cartridge 1, and a carrier is used to selectively transfer and supply the cartridge 1 pulled out from each storage shelf 3 of the stocker 2 to both players 4 and 5. While the cartridge 6 is being vertically transferred in the Ya direction, the cartridge 1 taken from both players 4 and 5 is stored in the original storage shelf 3 of the stocker 2.
While the carrier 6 is being vertically transferred in the Yb direction to return to
The cartridge 1 is rotated 180° in each direction.
The configuration is such that selection (switching) between side A and side B of the disc within the disc is performed.

This disk file device also enables high-speed writing of information by both players 4 and 5, and is stored in the stocker 2 by a series of operations that are exactly the same as the above-mentioned high-speed reading operation of information. It is possible to sequentially and continuously draw out a large number of cartridges 1, and write information on the disks in the cartridges 1 sequentially and continuously.

The 180° reversal mechanism of the G2 carrier will be explained with reference to Figures 3 and 4.

First, the elevating frame 17 of the carrier 6 has a horizontal shape, and a mounting plate 21 is vertically fixed to one end thereof. On the side of the mounting plate 21, there are a total of four guide rollers 22, one pair each on the upper and lower sides. It is rotatably pivoted. Then, a guide roller 2 is attached to a guide rail 24 fixed perpendicularly to the side surface of the support column 23.
2 are engaged, and a portion of the timing belt 8 is fixed to its mounting plate 21. Therefore, the elevating frame 17 is configured to be cantilevered, driven by the timing belt 8, guided by the guide rail 24, and vertically moved at high speed in the direction of arrow Y while remaining horizontal.

Next, a cartridge holding part 26 is provided inside the reversing frame 18, and this reversing frame 18 has a pair of brackets at both ends of a rotating shaft 27 that is horizontally and rotatably supported at the tip of the elevating frame 17. 28
It is fixed through. Note that this rotation axis 27 is in the left-right width direction of the reversing frame 18 (left-right direction in FIG. 4).
The axis of this rotation shaft 27 is the rotation center line X'. A motor pulley 30 of a motor 29 mounted within the lifting frame 17 and a pulley 31 fixed to the rotating shaft 27 are interlocked by a timing belt 32.

Further, as described above, the pull-out claw transfer means 13 for moving and driving the pair of left and right pull-out claws 12 is provided on the upper surface side 18a of the reversing frame 18 in FIG. Of the respective pairs of pulleys 34 and 35, the pair of pulleys 34 on one end side are connected by an interlocking rotating shaft 36. Further, the motor 15 is installed within the reversing frame 18, and the motor pulley 37 and the interlocking rotating shaft 3
6 is a timing belt 38, a pulley 39, an intermediate rotating shaft 40, a pulley 41, and a timing belt 42.
and are interlocked via a pulley 43. Then, claw mounting plates 46 extending from a pair of left and right sliding bodies 45 to which parts of both timing belts 14 are fixed and sliding along both guide rails 16 are inserted through both slits 19 to form a cartridge holding part. A pair of left and right pull-out claws 12 inserted into the cartridge holding portion 26 and disposed within the cartridge holding portion 26 are fixed to the claw mounting plate 46 .

Next, both pull-out claws 12 are connected to the cartridge holding portion 26.
The connecting plates 45 and 45 are connected to each other by a connecting plate 47 so that they can be moved together.
is also used as a lock release means. Two photo sensors 48 and 49 are provided on the upper surface side 18a of the reversing frame 18 to detect the two positions of the pull-out claws 12, which are the pull-out position shown by solid lines in FIG. Both photo sensors 48 and 49 are configured to be turned on and off by a shutter 50 provided on the sliding body 45 to which one of the pull-out claws 12 is attached. A plurality of guide rollers 51 are rotatably mounted along both left and right sides of the cartridge holding section 26 at predetermined intervals.

Next, a pair of left and right lock levers 52, 53 are attached to the lower surface side 18b of the reversing frame 18 in FIG. Both lock levers 5
A locking plate 54, on which the lock plate 2 is selectively locked, is fixed to the side surface 17a of the lifting frame 17. These two lock levers 52, 53 and the lock plate 5
4 constitute a lock mechanism 55.

The details of the G3 carrier's reversal lock mechanism are explained in the first part.
This will be explained with reference to the drawings and FIG. Note that both lock levers 52 and 53 are symmetrical to each other, and only one lock lever 52 will be described here.

First, the lock lever 52 is approximately L-shaped and is rotatably supported on the lower surface side 18b of the reversing frame 18 via a fulcrum shaft 56. A lock pin 57 is horizontally fixed to the side surface of one end 52a of the lock lever 52, and a roller 58 is vertically mounted on the other end 52b via a support shaft 59. Then, the roller 58 is inserted through the opening 63 provided in the reversing frame 18 and is inserted into the cartridge holding section 26.
The lock lever 52 is vertically inserted into the lock lever 52 from below, and the lock lever 52 is urged to rotate in the direction of arrow a by a return spring 60. Next, a lock plate 54 is vertically fixed to the side surface 17a of the elevating frame 17, and a pair of upper and lower lock pins 57 of each of the pair of left and right lock levers 52, 53 are selectively engaged with the lock plate 54. Lock holes 61 and 62 are provided. Two photo sensors 64 and 65 are provided on the side surface 17a of the lifting frame 17 for detecting two positions of the reversing frame 18: an upper reversing position indicated by a solid line in FIG. 4 and a lower reversing position indicated by a dashed line. Both photo sensors 6
4 and 65 are configured to be selectively turned on and off by a pair of shutters 66 and 67 attached to both left and right ends of the lower surface side 18b of the reversing frame 18.

The 180° reversal and locking operations of the G4 carrier will be explained with reference to FIGS. 1 to 4.

First, when both the pull-out claws 12 are pulled out to the pull-out position shown by solid lines in FIG.
is separated from both rollers 58 of both lock levers 52 and 53 in the direction of arrow Xb, and in this state, one lock lever 52 moves the reversing frame 18 to the fourth position.
It is locked in the horizontal position in the upper inverted position shown by the solid line in the figure.

That is, as shown by the solid line in FIGS. 1 and 2, one of the lock levers 52 is rotated in the direction of arrow a by the return spring 60, and the lock pin 57 is horizontally inserted into the upper lock hole 61 of the lock plate 54. The reversing frame 18 is horizontally fixed to the elevating frame 17 by being engaged with the reversing frame 18 . In this state, as shown by the solid line in FIG. 3, the shutter 50 turns off the photo sensor 48 and detects that both pull-out claws 12 are in the pulled-out position, and as shown in FIGS. As shown by the solid line, the photo sensor 64 is turned off by the shutter 66, and the reversing frame 18 is turned off.
is detected to be in the top inverted position.

In the levered state, however, both pull-out claws 12 are engaged in both grooves 11 of the cartridge 1 housed in the stocker 2, for example, as shown in FIG. Therefore, when a command signal for withdrawing the cartridge 1 is issued to the carrier 6, the motor 15 is driven to rotate in the forward direction, and the timing belt 38, intermediate rotating shaft 40,
Both timing belts 14 are driven in the direction of the arrow Xa in FIG. 3 via the timing belt 42 and the interlocking rotation shaft 36, and the cartridge 1 is pulled out from inside the stocker 2 by the two drawer claws 12 in the direction of the arrow Xa in FIG. It is pulled out and pulled horizontally into the cartridge holding part 26 of the carrier 6.

3, when the cartridge 1 is completely retracted into the cartridge holding frame 26 and both pull-out claws 12 reach the retracted position,
The lock of the reversing frame 18 by one of the lock levers 52 is automatically released.

That is, when both the pull-out claws 12 reach the retracted position as shown by the one-dot chain line in FIGS. 2 and 3, the connecting plate 47
is brought into contact with the rollers 58 of both lock levers 52, 53, and one of the lock levers 52 is rotated in the direction of arrow b in FIGS. 1 and 2 against the return spring 60. As a result, the lock pin 57 is removed from the upper lock hole 61 of the lock plate 54, and the horizontal state of the reversing plate 18 is unlocked. Incidentally, when both the pull-out claws 12 reach the retracted position as shown by the one-dot chain line in FIG. 3, the photo sensor 49 is turned off by the shutter 50, this is detected, and the motor 15 is stopped.

Next, as described above, while the carrier 6 is vertically transporting the cartridge 1 in the direction of the arrow Ya or Yb, when a command signal for reversing the cartridge 1 by 180° is issued to the carrier 6, the motor 29 is driven to rotate in the forward direction.
The rotation axis 27 is rotated 180° by the timing belt 32.
By being rotated, the reversing frame 18 is reversed by 180° in the direction of arrow Za from the upper reversing position indicated by the solid line in FIG. 4 to the lower reversing position indicated by the dashed-dotted line in FIG. When the reversing frame 18 becomes horizontal again at the lower reversing position, the photo sensor 65 is activated by the shutter 67.
is turned off, this is detected, and the motor 29
will be stopped.

Note that by reversing the reversing frame 18 by 180°, the fourth
As shown by the dashed line in the figure, the lock pin 57 of the other lock lever 53 is now opposed to the lower lock hole 62 of the lock plate 54.

However, after this, the cartridge 1 was inserted into the carrier 6.
When the push-out command signal is issued, the motor 15 is driven to rotate in reverse, and the cartridge 1 in the cartridge holder 26 is pushed out in the direction of arrow Xb in FIG. 3 by both pull-out claws 12. 12 is the third
At the moment when the reversing frame 18 is moved a little in the direction of arrow Xb from the retracted position indicated by the one-dot chain line in the figure, the reversing frame 18 is brought into a horizontal state at the lower reversing position indicated by the one-dot chain line in Fig. 4 by the other lock lever 53. It will be automatically locked again.

That is, when both pull-out claws 12 are moved in the direction of arrow Xb, the connecting plate 47 is separated from both rollers 58 of both lock levers 52 and 53 in the direction of arrow Xb. As a result, the other lock lever 53 returns to the spring 60.
1, and the lock pin 57 is horizontally engaged in the lower lock hole 62 of the lock plate 54 as shown by the dashed line in FIGS. 1 and 4. , the reversing frame 18 is the elevating frame 17
It is fixed again horizontally.

This locked state of the reversing frame 18 is maintained until both the pull-out claws 12 return to the retracted position indicated by the dashed-dotted line in FIG. 3 again.

Although one embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and various effective changes can be made based on the technical idea of the present invention.

For example, 180° of the cartridge holding frame in this invention.
The reversing mechanism, its locking mechanism, and lock release means may have any structure.

Furthermore, the present invention is applicable to various disk file devices capable of storing document information, video information, audio information, or a mixture thereof using disks, and is applicable to playback (reading) only devices or recording (writing) devices. The present invention is applicable to any recording/reproduction device capable of both reproduction (reading) and reproduction.

H. Effects of the invention The present invention enables the cartridge holding part to be rotated 180 degrees only when the pull-out claw of the carrier is pulled into the cartridge retraction position within the cartridge holding part, and when the pull-out claw of the carrier is at a position other than the cartridge retraction position. In this state, the cartridge holder can be locked in a non-reversible state, so if there is a failure in the system control circuit, etc., the pull-out claw is engaged with the cartridge in order to pull it out from the stocker. Even if the cartridge holding part should be inadvertently reversed during operation or during the cartridge withdrawal operation, the cartridge holding part will not be reversed at all, resulting in extremely high safety. In addition, if the power is cut off due to a power outage while the pull-out claw is engaged with the cartridge of the stocker,
When the power is turned on next time, the pull-out claw can be safely returned to its original position to the cartridge retracting position within the cartridge holding section.
