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 Unexamined Patent Publication No. 59-30263. 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. 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 and heavy stocker is transferred horizontally, and this large and heavy stocker cannot be transferred parallelly at high speed, so it is difficult to quickly search for cartridges in the stocker and to send the player to the player. 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 searching of cartridges in the stocker and high-speed supply of cartridges to the player, and in particular, prevents the cartridge ejected from the player from interfering with the carrier unexpectedly after writing or reading information. like,
This makes it possible to accurately stop the cartridge at a fixed position.

[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. and a carrier that is linearly transferred along the front side of the player, and the tips of a pair of pull-out claws provided on the carrier are attached to both sides of one end of a large number of cartridges stored in the stocker. The cartridge is selectively engaged with a pair of grooves provided in the stocker, and the cartridge is selectively pulled out from the stocker by the pair of pull-out pawls, and the pulled-out cartridge is transferred to the front position of the player by the carrier, and then the pair of drawers are pulled out. The cartridge is configured to be pushed out from the carrier and inserted into the player by a claw, and when the cartridge inserted in the player is ejected from the cartridge insertion slot on the front of the player after writing and reading the above information, the cartridge is inserted into the player. This disk file device is provided with a stopper for stopping the cartridge at a fixed position, and a reciprocating drive mechanism for reciprocating the stopper between an operating position in front of the cartridge insertion opening and a non-operating position outside the cartridge insertion opening. .

According to the present invention configured in this manner, a large and heavy stocker is fixed and a small and lightweight carrier is transported at high speed, thereby enabling high-speed searching of a large number of cartridges in the stocker and delivery of cartridges to the player. High-speed supply is possible.

Moreover, according to the present invention, in particular, writing of information,
After reading, the cartridge ejected from the player can be accurately stopped at a fixed position by the stopper, so the carrier can be transferred even if the cartridge ejection stop position is incorrect.
An inconvenience in which the pair of pull-out claws of the carrier are not accurately engaged within the pair of grooves of the cartridge, and the pair of pull-out claws unexpectedly interfere (collide) with a portion of the cartridge other than the pair of grooves. does not occur.

Further, according to the present invention, the reciprocating drive mechanism is configured to allow the stopper to reciprocate between an operating position in front of the cartridge insertion opening and a non-operating position away from in front of the cartridge insertion opening. Therefore, the stopper should be moved to the operating position only when the cartridge is inserted into the player, and when transferring the cartridge between the carrier and the player, the stopper should be moved so that it does not become an obstacle to the transfer of the cartridge. It can be moved back to the non-operating position.

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 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 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 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 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 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. The specified cartridge 1 is supplied from the carrier 6 to the player 5 at the lower part 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

4, it is rotationally biased in the direction of arrow a' in FIG. Further, as shown in FIGS. 5, 6, and 8, a pair of left and right optical sensors 47 are attached to the front panel 21 to detect the rotational position of the lower arm 27b of both detection levers 27. At this time, as shown in FIG. 8, the lower arms 27b of both detection levers 27 are formed sufficiently long with respect to the upper arm 27a, and the small holes 48 provided at the lower ends of the sufficiently long lower arms 27b are An optical sensor 47 is configured to detect it. Therefore, the upper and lower arms 27a,
By using the lever ratio of 27b, both optical sensors 47 can detect the positions of both detection members 28 in an enlarged state. 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.

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 it is detected that the cartridge 1 has been inserted into the player 4 as described above, the plunger solenoid 35 is energized and the plunger 36 is attracted in the direction of 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.
are positioned, and gaps G are formed between both side surfaces 11a and 11b of both grooves 11 and both side surfaces of 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' following the rear end surface 1c.

When both detection levers 27 reach the first detection position indicated by the solid line in FIG. 12th
Both pull-out claws 12 are pushed in to the position indicated by the one-dot chain line in the figure.
It is detected that the above-described positioning operation of both grooves 11 with respect to the tip 12a of the groove 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
is never brought into contact with both side surfaces 11a, 11b of both grooves 11.

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 a positioning operation has been performed such that a does not interfere with the cartridge 1.

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. The spring force of the spring 44 rotates 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. Moved forward in the Xb direction. 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 both optical sensors 47 do not detect the ejection of the cartridge 1 to the outside of the player 4, both stoppers 26 are held at the operating positions shown by 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 2.
6 and cannot enter into player 4. Both stops 26 therefore prevent double insertion of the cartridge 1 into the player 4.

[Application example]

The present invention is applicable to various types of 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) devices. 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 searching of cartridges in the stocker and high-speed supply of cartridges to the player, so that a large amount of information on a disk can be read at high speed. Furthermore, according to the present invention, the cartridge ejected from the player after information has been written or read can be precisely stopped at a fixed position by the stopper. When the carrier is moved, the pair of pull-out claws of the carrier are not accurately engaged in the pair of grooves of the cartridge, and the pair of pull-out claws accidentally interfere with (collide with) a part of the cartridge other than the pair of grooves. Therefore, it is possible to prevent an accident in which the pair of pull-out claws or the cartridge is damaged. Therefore, safety can be significantly improved.

Furthermore, according to the present invention, when transferring a cartridge between the carrier and the player, the stopper is moved from an operating position in front of the cartridge insertion opening to a non-operating position in front of the cartridge insertion opening so as not to obstruct the cartridge transfer. Since the cartridge can be moved back to the specified position, the above-mentioned cartridge can always be transferred smoothly.

The stopper of the present invention also has a function of preventing double insertion of cartridges into the player, and is extremely safe.
