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. A disk file that can be selectively pulled out from a large number of disks at high speed and supplied to a recording/reproducing device that performs at least one of writing and reading information. It is related to the device.

[Background technology and its problems]

As a known example, there is, for example, Japanese Unexamined Patent Publication No. 59-30263. This known example consists of an oblong horizontal stocker in which a plurality of thin cartridges with trays stored inside are stored vertically and parallel to each other, and the stocker is placed in front of the stocker. The apparatus includes a pull-out mechanism having a pair of upper and lower pull-out claws, and a player disposed beside the pull-out mechanism for writing and reading at least information. Then, by horizontally moving the stocker, a pair of pull-out claws are moved relatively within a pair of grooves provided on both upper and lower sides of one end of the cartridge, thereby searching for multiple cartridges stored in the stocker. I do.
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, a large, large-capacity stocker is horizontally transferred, and this large, heavy stocker cannot be horizontally transferred at high speed. Cartridges cannot be fed at high speed. Therefore, information on the disk could not be read out at high speed.

[Purpose of invention]

The present invention enables high-speed retrieval of cartridges in a stocker and high-speed supply of cartridges to a recording/reproducing device, and in particular, the cartridge is ejected from the recording/reproducing device after information is written or read in a location close to the ejecting position. The carrier may move unnecessarily even though it has not been ejected.
Furthermore, it is possible to detect that the cartridge has been ejected to the vicinity of its ejection position so that the cartridge does not unexpectedly interfere with the carrier.

[Summary of the idea]

The present invention provides a stocker in which a number of thin cartridges with disks stored therein are stored in parallel in a number of storage shelves, and at least one of writing and reading information to and from the disks in each cartridge. A recording and reproducing device that performs the recording and reproducing device, and a carrier that is linearly transported along the front side of the stocker and the recording and reproducing device, and the tips of a pair of pull-out claws provided on the carrier are stored in the stocker. The cartridges are selectively engaged with a pair of grooves provided on both sides of one end of a large number of cartridges, and the cartridges are selectively pulled out from the stocker by the pair of pull-out claws, and the pulled-out cartridges are recorded by a carrier. After the cartridge is transferred to the front position of the playback device, it is pushed out from the carrier by a pair of pull-out claws and inserted into the recording and playback device, and the cartridge inserted in the recording and playback device reads the information after writing or reading the above information. When the cartridge is ejected from the cartridge insertion slot on the front side of the playback device to the outside of the recording/playback device, the cartridge insertion slot indicates that the cartridge has been ejected to the vicinity of a predetermined ejection position corresponding to the position where the pair of pull-out claws wait. a reciprocating drive mechanism for reciprocating the detection member between a detection position in front of the cartridge insertion opening and a non-detection position located outside the front of the cartridge insertion opening;
When the detection member detects the ejection of the cartridge, the pair of pull-out claws engage the tip end of the cartridge with the pair of grooves of the cartridge and draw it into the carrier, and then the carrier The cartridge was brought from the front position of the recording/reproducing device to the front position of the designated storage shelf of the stocker,
Furthermore, the disk file device is configured such that the pair of pull-out claws push out the cartridge from the carrier and insert it into the predetermined storage shelf.

According to the present invention configured in this way, a large, large-capacity stocker is fixed, and a small, lightweight carrier is transported at high speed, so that a large number of cartridges in the stocker can be searched at high speed and sent to a recording/reproducing device. Cartridges can be fed at high speed.

Moreover, according to the present invention, in particular, by detecting with the detection member that the cartridge ejected from the recording/reproducing apparatus after writing or reading information has been ejected to the vicinity of the ejection position, the pair of drawers of the carrier can be removed. Since the tip of the claw engages with a pair of grooves in the cartridge to pull it into the carrier, the carrier may move unnecessarily even though the cartridge has not been ejected to the vicinity of the ejection position. Also, the carrier moves,
Inconveniences such as the pair of pull-out claws of the carrier accidentally interfering (colliding) with parts other than the pair of grooves of the cartridge do not occur.

Further, according to the present invention, the reciprocating drive mechanism is configured to allow the detection member to reciprocate between a detection position in front of the cartridge insertion opening and a non-detection position located outside the front of the cartridge insertion opening. Therefore, the detection member is moved to the detection position only when the cartridge is inserted into the recording/playback device, and when the cartridge is transferred between the carrier and the recording/playback device, the detection member is moved to the detection position of the cartridge. It is possible to return to the non-detection position so as not to interfere with the delivery.

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 being supplied, 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 and engaged in both grooves 11 of the used cartridge 1 of the lower player 5.

Note that after the tips 12a of both pull-out claws 12 move from the position to the upper player 4,
The supplied cartridge 1 is drawn into the player 4, and the information written on the disk within the cartridge 1 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 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 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 and the stocker 2 to which the transferred 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 moved in the Ya direction to search for the next cartridge 1 to be pulled out.
It is vertically transferred along both grooves 11 of.

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 tips 12a of the two pull-out claws 12 are used to retrieve 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. A designated cartridge 1 is supplied from the carrier 6 to the lower player 5 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. both grooves 1 of used cartridge 1

It is rotationally biased in the a direction. Further, as shown in FIGS. 5, 7, and 9, a pair of elongated holes 33 are formed in a pair of left and right upright pieces 32 that are integrally provided at the rear end of the rotating member 24 at approximately the center position in the left-right direction. A pin 34 is horizontally inserted between both long holes 33. A substantially U-shaped connecting member 27 is attached to the upper end of the plunger 36 of the plunger solenoid 35 vertically attached to the front panel 21. It is rotatably supported almost in the center. Further, a long hole 39 is vertically provided at the upper end of the vertical solenoid mounting plate 38 that attaches the plunger solenoid 35 to the front panel 21, and a long hole 39 is provided horizontally at the upper end of the plunger 36 and the lower end of the connecting member 37. One end of the pin 40, which is attached through the pin 40, is inserted horizontally into the elongated hole 39. The plunger solenoid 35 is of a self-holding type, and once it is energized, it holds the plunger 36 in a attracted state in the direction of arrow b until it is energized again.

Next, as shown in Figures 6, 8 and 10,

As shown in FIGS. 5 and 6, a pair of left and right guide rollers 49 are provided at both left and right ends of the cartridge insertion slot 22 of the front panel 21 to guide the cartridge 1 inserted therein and to ensure smooth insertion. is rotatably mounted.

Then, move the stoppers 26 between the operating position in front of the cartridge insertion opening 22 shown by a solid line in FIG. While reciprocating in the direction, both detection members 28 are moved to the detection position in front of the cartridge insertion port 22 shown by solid lines and dotted lines in FIG.
A reciprocating drive mechanism 55 that reciprocates between the rotation member 24 and a non-detection position located downward from the rotation member 24, the plunger solenoid 35, and parts related thereto.

Next, the positioning operation of the cartridge 1 supplied to the player 4 based on the above configuration will be explained.

First, as explained in FIG. 1, after the carrier 6 is transferred to the front position of the player 4 and stopped, as explained in FIG.
is driven by the motor 15, and both pull-out claws 12 are horizontally transferred in the direction of arrow Xb from the retracted position indicated by the dashed line in FIG. 3 to the pulled-out position indicated by the solid line. Then, the 11th
As shown in the figure, the cartridge 1 is held horizontally in the cartridge holding part 50 of the carrier 6, and the tips 12a of both pull-out claws 12 are engaged in both grooves 11. The cartridge 1 is pushed out horizontally in the direction of
It is inserted horizontally from the direction.

At this time, the cartridge 1 is inserted into a cartridge holder 51 provided in the player 4, but there is a load resistance such as a cartridge pressing spring inside the cartridge holder 51.
The cartridge 1 is pushed into the cartridge holder 51 against its load resistance.

Further, when both pull-out claws 12 reach the above-mentioned pull-out position, the shutter 52 integrated with both pull-out claws 12 is detected by a pair of left and right optical sensors 53 attached to the reversing plate 18, as shown in FIG. The motor 15 is stopped, and the completion of insertion of the cartridge 1 into the player 4 is detected.

Therefore, when the cartridge 1 is pushed out from the carrier 6 by both pull-out claws 12 and completely inserted into the player 4, the tips 12a of both pull-out claws 12 are in one of the grooves 11, as shown by the solid line in FIG. is in contact with the side surface 11a of.

Next, when the completion of insertion of the cartridge 1 into the player 4 as described above is detected, the plunger solenoid 35 is energized and the plunger 36 is attracted in the direction of the arrow b in FIGS. Then, the rotating member 24 rotates in the direction of arrow a' through the connecting member 37 and pin 34 against the tension spring 31 from the backward movement position shown by the dashed line in FIG. 7 to the forward movement position shown by the solid line. be done. And this rotating member 24
A pair of left and right stoppers 26 attached to the rear end face 1c of the cartridge 1 are brought into contact with the rear end surface 1c of the cartridge 1 as shown in FIGS. Push it a little further in the direction of arrow Xb until it reaches the desired position. At this time, the pushing position of the cartridge 1 by both stoppers 26 is regulated by the pin 40 coming into contact with the lower end of the long hole 39 of the solenoid mounting plate 38 and being stopped, as shown by the solid line in FIG. be done.

When the cartridge 1 is pushed in the direction of arrow Xb to the position shown by the dashed-dotted line in FIG.
Both pull-out claws 12 are located approximately at the center of the groove width W of both grooves 11.
Both grooves 11 are positioned so that the tips 12a of the two grooves 11 are located, and gaps G are formed between both side surfaces 11a and 11b of both grooves 11 and both sides of the tips 12a of both pull-out claws 12.

On the other hand, when the rotating member 24 is rotated in the direction of arrow a' in FIG. 7, both detection levers 27 follow it and move from the backward movement position indicated by the dashed dotted line to the first detection position indicated by the solid line in FIG. It is rotated in the direction of arrow a′. In addition, at this time,
Both detection levers 27 are biased to rotate in the direction of arrow a' in FIG.
8 is rotated in the direction of arrow a' in advance of both stoppers 26 by the amount of play of pin 42 in both pin insertion holes 43. Similar to both stoppers 26, these detection members 28 come into contact with the rear end surface 1c of the cartridge 1, as shown in FIGS. 6, 8, and 12, and are rotated in the direction of arrow a' in accordance with the rear end surface 1c. .

When both detection levers 27 reach the first detection position indicated by the solid line in FIG. 1st
In Figure 2, both pull-out claws 1 are pushed in to the position indicated by the chain line.
It is detected that the above-described positioning operation of both grooves 11 with respect to the tip 12a of the groove 2 is completed. The pair of left and right optical sensors 47 also detect the parallelism of the cartridge inserted into the player 4.

Then, only when the completion of the positioning operation of the cartridge 1 as described above is detected, vertical movement of the carrier 6 in the direction of the arrow Y explained in FIG. 1 is permitted. After that, when the carrier 6 is vertically transferred in the direction of the arrow Y, both sides 11a and 11b of both grooves 11 and both sides of the tips 12a of both pull-out claws 12 are Since a gap G is formed in
are both sides 11a of both grooves 11, . There is no contact with 11b at all.

In short, when the cartridge 1 is pushed by both stoppers 26 to the position indicated by the one-dot chain line in FIG.
This means that the cartridge 1 has been positioned such that the grooves 11 of the cartridge 1 and the grooves 11 of the cartridge 1 do not interfere with each other.

Note that after the carrier 6 is vertically transferred from the front position of the player 4 in the direction of arrow Y in FIG.
1, the cartridge 1 is pulled into the player 4 in the direction of arrow d by the cartridge holder 51, and the cartridge 1
The information written on the internal disk is read. After the reading is completed, the cartridge 1 is moved to the 11th cartridge by the cartridge holder 51.
The cartridge 1 is ejected in the direction of arrow d' to the original position shown by the solid line in the figure. At this time, both stoppers 26 act as positioning stoppers for the cartridge 1 to be ejected, and both detection members 28 act as positioning stops for the cartridge 1 to be ejected. Detects the ejection position.

That is, first, when the cartridge 1 is pulled into the player 4 from the insertion position shown in FIG. 8 by the spring force of 44 in the direction of arrow a' from the first detection position indicated by the solid line to the second detection position indicated by the dotted line in FIG.
is moved forward in the direction of arrow Xb. Then, the small hole 48 at the lower end of the lower arm 27b of both detection levers 27 is removed from the optical sensor 47 in the direction of arrow a' as shown by the dotted line.

On the other hand, both stoppers 26 are held in the operating position shown by solid lines in FIG. 7 by a self-holding plunger solenoid 35.

Next, as described above, when the cartridge 1 is ejected from the player 4 in the direction of the arrow Xa in FIGS. is pushed in the direction of arrow Xa, and both detection levers 27 are rotated in the direction of arrow a from the second detection position indicated by a dotted line in FIG. 8 against both torsion springs 44.

On the other hand, the rear end surface 1c of the ejected cartridge 1 is attached to both stoppers 26 as shown by solid lines in FIG.
It comes into contact with and stops at a certain position.

Then, at the moment when the rear end surface 1c of the cartridge 1 comes into contact with both stoppers 26, both detection members 28
is pushed back to the first detection position indicated by the solid line in Fig. 8,
The small holes 48 at the lower ends of the lower arms 27b of both detection levers 27 are detected by both optical sensors 47, and the ejection position of the cartridge 1 to the outside of the player 4 is detected.

Therefore, the ejection stop position of the cartridge 1 that has been ejected and stopped at a certain position by both stoppers 26 is the position shown by the dashed line in FIG. Due to the vertical movement of the pull-out claws 12, the tips 12a of both the pull-out claws 12 can accurately enter into approximately the center position of the groove width W of both the grooves 11 without coming into contact with the cartridge 1.

Furthermore, as mentioned above, if the cartridge 1 is correctly ejected to the outside of the player 4, the cartridge 1
When both optical sensors 47 detect the discharge position, the plunger solenoid 35 is energized again and the suction of the plunger 36 is released. Then, the rotation member 24 is rotated by the tension spring 31 in the direction of the arrow a to the return position indicated by the dashed line in FIG. The stoppers 26 are rotated in the direction of the arrow a to the return position indicated by the dashed dot line in FIG. is returned to the non-detection position.

Therefore, after this, the cartridge 1 is transferred between the carrier 6 and the player 4 as shown in FIGS.
When the cartridge 1 is transferred in the directions of arrows Xa and Xb in the figure, both stoppers 26 and both detection members 28 do not obstruct the transfer of the cartridge 1 at all.

As long as the optical sensor 47 does not detect the ejection of the cartridge 1 to the outside of the player 4, the stoppers 26 are held at the operating position shown by the solid lines in FIG. Even if another cartridge 1 is inserted into the player 4 while the cartridge 1 is being drawn into the player 4 and information is being written or read, that cartridge 1 will be inserted into both stoppers 26.
It is not possible to enter player 4 due to contact with the player. Both stops 26 therefore prevent double insertion of the cartridge 1 into the player 4.

Although one embodiment of the present invention has been described above, various modifications can be made based on the technical idea of the present invention.

For example, the carrier and both pull-out claws are not limited to the structures shown in the embodiments, but can be changed to various structures.

Further, the carrier transfer means and the pull-out claw transfer means are not limited to the structures shown in the embodiments, but can be changed to various structures.

In addition, when using a single-sided cartridge, use the carrier reversal plate shown in the example to
No inverted structure is required.

In addition, in the embodiment, a large number of horizontal cartridges were stored vertically and parallel in a vertically long stocker, but the cartridges were placed vertically using a horizontally long stocker. so that it is stored parallel to the horizontal direction,
It is also possible to arrange for the carrier to be transported horizontally along the front side of the stocker.

Further, in the embodiment, a plurality of players are arranged below the stocker, but a plurality of players may be arranged above the stocker, or they may be arranged above and below the stocker.

Further, the detection member 28 and its reciprocating drive mechanism 55 are not limited to the structure shown in the embodiment, but can be changed to various structures.

[Application example]

The present invention is applicable to various disk file devices that can store document information, video information, audio information, or a combination of these information using disks, and is applicable to playback (reading) only devices or recording (writing), The present invention is applicable to any recording/reproducing device capable of both reproduction (reading).

[Effect of idea]

As described above, the present invention enables high-speed retrieval of cartridges in a stocker and high-speed supply of cartridges to a recording/reproducing device, so that a large amount of information on a disk can be read at high speed.

Moreover, according to the present invention, in particular, by detecting with the detection member that the cartridge ejected from the recording/reproducing apparatus after writing or reading information has been ejected to the vicinity of the ejection position, the pair of drawers of the carrier can be removed. Since the tip of the claw engages with a pair of grooves in the cartridge to pull it into the carrier, the carrier may move unnecessarily even though the cartridge has not been ejected to the vicinity of the ejection position. Also, the carrier moves,
It is possible to prevent an accident in which the pair of pull-out claws of the carrier unexpectedly interferes with (collides with) a portion of the cartridge other than the pair of grooves, thereby damaging the pair of pull-out claws and the cartridge. Therefore, safety can be significantly improved.

Furthermore, according to the present invention, when transferring a cartridge between the carrier and the recording/reproducing device,
Since the detection member can be moved back from the detection position in front of the cartridge insertion opening to the non-detection position outside the front of the cartridge insertion opening so that the detection member does not become an obstacle to the delivery of the cartridge,
The above-mentioned cartridges can always be delivered smoothly.
