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 includes a plurality of thin cartridges each containing disks stored therein, which are stored vertically and parallel to each other in the horizontal direction, and which is configured to be movable in the horizontal direction. It consists of a pull-out mechanism that has a pair of upper and lower pull-out claws placed on the front, and a player placed next to the pull-out mechanism. Then, by moving the stocker horizontally, a 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 pull out the pair of drawers. The designated cartridge is selectively pulled out in front of the stocker by the claw. The drawn cartridge is then supplied to a player to perform recording and playback on the disc in the cartridge.

However, this known example does not have a structure in which it is not possible to provide a cartridge reversing device that rotates the cartridge pulled out from the stocker by 180 degrees and supplies it to the player. Therefore, in this known example, only a single-sided disk can be used, and it is completely impossible to use a double-sided disk and record and play back on both sides of the disk while freely reversing the A and B sides of the cartridge. Because this is not possible, there was a defect that the amount of information in the file was limited.

[Purpose of invention]

By equipping the carrier with a cartridge reversing mechanism, the present invention enables the A and B sides of the cartridge pulled out from the stocker to be freely reversed and supplied to the player. In this case, 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, so that the reversing mechanism is supported while the cartridge is being transferred by the carrier. To prevent wobbling from occurring in the cartridge, and also to enable cartridges with A and B sides reversed to be accurately delivered to each storage shelf of a player and a stocker each time.

[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. It has a carrier for transporting cartridges selectively pulled out from the player and supplying them to the player, a reversing plate is provided in the almost U-shaped frame of the carrier, and a pair of support shafts are provided on one side of the reversing plate. and a cartridge holding part 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 pivoted to the frame by these pair of support shafts so that it can rotate freely by 180 degrees, and a motor is arranged on the same axis between these pair of support shafts. The cartridge is rotated and the cartridge pulled out from the stocker is held in the cartridge holding part of the reversing plate, and while the cartridge is being transferred to the player by the carrier, the reversing plate is rotated by the motor.
The A and B sides of this cartridge can be reversed by rotating 180 degrees, and two first sensors are provided on the frame to detect the 180 degree rotated position of the reversing plate. 180°
Two second sensors are provided on the frame, and the second sensors are disposed in correspondence with the two inverted positions of the cartridge holder whose positions are inverted on both sides of the pair of support shafts as the cartridge rotates, respectively. is configured as a sensor that detects a large number of detected parts provided at each storage shelf position of the stocker and at the cartridge supply position of the player, and when the reversing plate is rotated 180 degrees while the cartridge is being transferred by the carrier, the above two points are detected. One of the first sensors detects the 180° rotated position of the reversing plate, and one of the two second sensors is arranged on the side corresponding to the inverted position of the cartridge holder. The second sensor is switched to the operating state, and the carrier being transported is stopped by the detection operation of the detected portion by one of the second sensors, and the cartridge holding portion whose position has been reversed is moved to the cartridge supplying position of the player. and a disk file device configured to be positioned at a position opposite to a predetermined storage shelf position of a stocker.

According to the present invention constructed in this manner, the A and B sides of the cartridge pulled out from the stocker can be freely reversed and supplied to the player. Moreover, because the motor that drives the reversing plate to rotate 180 degrees is placed between a pair of spindles, the motor is housed within the projected area of the reversing plate, and the motor is placed outside the side of the reversing plate. There is nothing that stands out in any way. 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. In addition, the reversing plate tends to be supported on a cantilever because cartridges are inserted and removed from one end of the reversing plate. By arranging the pair of support shafts at a distance in the direction of loading and unloading the cartridge, it was possible to support the reversing plate on both sides. Therefore, the reversing mechanism is supported extremely stably,
There is no wobbling of the reversing plate in the reversing mechanism during transport of the cartridge by the carrier.

Furthermore, by rotating the reversing plate 180°, the position of the cartridge holder is reversed to both sides of the pair of spindles, and the cartridge supply position of the player and the position of the cartridge holder relative to each storage shelf of the stocker are changed. However, the 180° rotated position of the reversing plate is detected by one of the two first sensors, and one of the two second sensors is placed on the side corresponding to the reversed position of the cartridge holder. The one second sensor is switched to the operating state, and the one second sensor detects the detected parts provided at each storage shelf position of the stocker and the cartridge supply position of the player, and detects the detected parts provided at the cartridge supply position of the player. To stop the carrier, the cartridge holder, which has been reversed to both sides of the pair of spindles by rotating the reversing plate 180 degrees, is moved to a position facing the cartridge supply position of the player and the predetermined storage shelf position of the stocker. Accurate positioning can be performed each time. Therefore, during transportation by the carrier, the cartridge with its A and B sides reversed can be accurately delivered to each storage shelf of the player and stocker each time. Moreover, at that time, 2
The two second sensors are offset in advance in accordance with the amount of offset of the cartridge holding section that is reversed on both sides of the pair of support shafts, so one of the second sensors can detect the detected section at a predetermined position. By simply detecting and stopping the carrier, the carrier can be accurately stopped at a predetermined position. Therefore, there is no need to perform troublesome and complicated control such as controlling the carrier transport distance each time by a distance corresponding to the offset amount of the cartridge holding portion, and the carrier transport can be controlled extremely easily.

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. It is hung 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 specified cartridge 1 is supplied from the carrier 6 to the player 5 at the bottom 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 have moved from the position to the lower player 5, the supplied designated 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 original position, the reversing plate 18 in the carrier 6 is each inverted 180° in the arrow Za or Zb direction around the rotation center line X', as shown in FIG. The configuration is such that selection (switching) between side A and side B of the disk in the cartridge 1 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.

When writing and reading information to and from the disk in the cartridge 1 using both players 4 and 5, there are two methods: rotating the disk while it is housed in the cartridge 1, and separating the upper and lower halves of the cartridge 1 into upper and lower halves. There is a method in which the disk is rotated in the state of the cartridge.If the latter method is adopted, after writing or reading the disk, the disk is sandwiched between the upper and lower halves of the cartridge 1 from above and below, and the top and bottom thickness of the cartridge 1 can be adjusted. This cartridge 1 can be made very thin.
The space factor when storing the stock in stocker 2 is greatly improved.

Next, the details of the reversing mechanism of the reversing plate 18 provided in the carrier 6 will be explained with reference to FIGS. 5 to 9B.

First, a pair of support shafts 21 and 22 are provided on one side 18a of the reversing plate 18, and a cartridge holding portion 23 is provided on the other side 18b. Note that the above-mentioned pull-out pawl transfer means 13 is also provided on one side 18a side.

Next, the pair of support shafts 21 and 22 are located at the center of the reversing plate 18 in the left-right width direction (left-right direction in FIG. 5), and the rotation center is parallel to the loading/unloading direction of the cartridge 1 (arrow X direction in FIG. 5). They are arranged horizontally on line X' with an interval l in the direction of insertion and removal. And these two support shafts 21 and 22 are the seventh
As shown in Figures A and 7B, a support plate 2 is fixed horizontally to the middle part of the frame 17 in the vertical thickness direction.
It is rotatably supported by a plurality of bracket parts 24a, 24b of 4, and both support shafts 21, 2
A pair of brackets 25 and 26 fixed to one side surface 18a of the reversing plate 18 are rotatably supported on the reversing plate 2. Note that one support shaft 21 is fixed to one bracket 25 by a set screw 27, and this support shaft 21 is configured to rotate together with the reversing plate 18.

Next, the motor 28 is placed between the pair of support shafts 21 and 22.
are arranged horizontally on the same axis, and this motor 28 is connected to one bracket part 2 of the support plate 24.
It is fixed to 4a. A motor shaft 29 of the motor 28 is integrally engaged with one of the support shafts 21 via a shaft coupling 30 so as to form the same axis. Note that the motor 28 has a built-in rotation angle detector 31 that detects the rotation angle of the motor shaft 29.

Next, the cartridge holding section 23 holds the cartridge 1
It has a flat housing shape corresponding to the upper and lower thicknesses of the stocker 2, and as shown in FIG.
The cartridge 1 is configured to be horizontally inserted and removed from an opening 33 at one end facing the a side. The pair of left and right pull-out claws 12 are configured to be transported along both left and right end positions within the cartridge holding section 23, and these two pull-out claws 12 are driven by the pair of left and right timing belts 14. A pair of left and right pull-out pawl drive members 34
is configured to be transferred via.

That is, as shown in FIG.
is configured to slide while being guided by the pair of left and right guide rails 16 fixed on one side surface 18a of the reversing plate 18, and one end 34a of both pull-out claw drive members 34 It is fixed to the timing belt 14. The other end 34b of both pull-out claw driving members 34 is inserted into the cartridge holding portion 23 by passing through the pair of left and right slits 19 provided in the reversing plate 18, and both pull-out claws 12 are inserted into the other end 34b. It is fixed. Note that the cartridge holding portion 2 is located at both the left and right end positions in the cartridge holding portion 23 and at the upper and lower positions of the other end 34b.
A pair of upper and lower guide rails 35 are provided for guiding the transfer of the cartridge 1 into and out of the cartridge 3.

Next, the operation of reversing the A and B sides of the cartridge 1 transported by the carrier 6 based on the above configuration will be explained.

First, both timing belts 14 are rotationally driven by the motor 15 in the direction Xa in FIGS. It is pulled in the Xa direction from the extrusion position to the retraction position shown by the solid line. As a result, the cartridge 1 in the stocker 2 or in the players 4 and 5 is pulled out by both pull-out claws 12 and horizontally drawn into the cartridge holding part 23 of the carrier 6. In contrast to this, both the timing belts 14 are rotationally driven in the Xb direction in FIGS.
1 from the retracted position shown in solid lines in Figures 5 and 6.
It is extruded in the Xb direction to the extrusion position shown by the dotted chain line.
As a result, the cartridge holding portion 23 of the carrier 6
The cartridge inside is pushed out by both pull-out claws 12 and pushed out horizontally into the stocker 2 or into the players 4 and 5.

Next, as shown in FIGS. 7A and 9A, while the cartridge 1 is horizontally drawn into and held in the cartridge holding portion 23 of the carrier 6, the motor 28 moves the motor 28 to one of the support shafts via the motor shaft 29. 21 is rotated 180° in the Za direction, the reversing plate 18 rotates in the Za direction around both support shafts 21 and 22.
The A and B sides of the horizontal cartridge 1 in the cartridge holder 23 are rotated 180° in the direction
From the state of Figures A and 9A to Figures 7B and 9B
It is flipped 180° to the state shown in the figure. However, on the contrary,
In the state shown in FIGS. 7B and 9B, one of the support shafts 21 is rotated by 180° in the Zb direction by the motor 28 via the motor shaft 29, so that the reversing plate 1
8 is rotated 180° in the Zb direction around both support shafts 21 and 22, and the A and B surfaces of the horizontal cartridge 1 in the cartridge holding part 23 are rotated as shown in FIGS. 7B and 9B.
180° from the state shown in the figure to the state shown in Figs. 7A and 9A.
be reversed.

At this time, the reversing position of the reversing plate 18 in FIGS. 7A and 9A or FIGS. 7B and 9B is determined by the motor 28.
The rotation angle is accurately detected by the rotation angle detector 31 built into the motor 2.
By applying a servo to 8, the reversing plate 18
7A and 9A or 7B and 9B
It is held horizontally in the reversed position shown in the figure.

However, A and B of the above cartridge 1
As explained in FIG. 1, the surface reversal operation occurs when the carrier 6 is vertically transferred in the Ya direction to transfer the cartridge 1 from the stocker 2 to the players 4 and 5, or when the carrier 6 is vertically transferred in the Yb direction. This is efficiently carried out while the cartridge 1 is being transferred from the players 4 and 5 to the stocker 2.

On the other hand, in this way, the A and B sides of the cartridge 1 pulled out from the stocker 2 can be freely reversed and supplied to the players 4 and 5. Information can be freely written and read on the B side.

Next, a structure for controlling the transfer of the carrier 6 in accordance with the reversing operation of the reversing plate 18 will be explained with reference to FIGS. 5 to 9B.

First, two first sensors 37, 3 detect the vertical position of the reversing plate 18 rotated by 180 degrees as shown in FIGS. 7A and 9A and FIGS. 7B and 9B.
8 is attached to the rear end side of the frame 17.
Note that both of these first sensors 37 and 38 are constituted by optical sensors each consisting of a light emitting element and a light receiving element (none of which are shown), and the reversing plate 18
A pair of left and right shutters 39 installed on the
40 are inserted alternately between the light emitting element and the light receiving element of both the first sensors 37, 38, so that detection outputs are alternately output from the two first sensors 37, 38. There is.

Next, the cartridge holding portion 23 provided on the other side of the reversing plate 18 is rotated by 180° rotation of the reversing plate 18, as shown in FIGS. 7A and 9A and 7B and 9B. The positions of the support shafts 21 and 22 are reversed vertically. As shown in FIGS. 5 and 6, a pair of upper and lower second sensors 41 and 42 are attached to one end of the front end of the frame 17, respectively, and are arranged to correspond to the vertically inverted positions of the cartridge holder 23. . That is, as shown in FIG. 6, the pair of upper and lower second sensors 41 and 42 are offset in advance on both upper and lower sides of the support shafts 21 and 22 in accordance with the vertical offset amount _l1 of the cartridge holding section 23 which is turned upside down. It is what is placed. Note that, like the first sensors 37 and 38, both of these second sensors 41 and 42 are also constituted by optical sensors consisting of a light emitting element and a light receiving element (none of which are shown).

Next, as shown in FIGS. 5 and 6, one end side of the front side 2a of the stocker 2 and both players 4,
A slit plate 4 is provided on one end side of the front side 4a, 5a of 5.
3 is mounted vertically, and this slit plate 43 is inserted between the light emitting element and the light receiving element of both second sensors 41,42. This slit plate 43 is provided with a large number of detected parts 44 made of slits.
4 are provided corresponding to the positions of each storage shelf 3 of the stocker 2 and the cartridge supply positions of both players 4 and 5 shown in FIG. Both second sensors 41 and 42 detect a predetermined detected portion 44 to drive the drive motor 9 of the carrier transfer means 7 described above.
It works to stop. Further, the first sensors 37 and 38 operate to detect the 180° rotated position of the reversing plate 18 and selectively switch the second sensors 41 and 42 into an operating state.

Next, a method for controlling the transfer of the carrier 6 in accordance with the reversing operation of the reversing plate 18 will be explained based on the structure as described above.

First, as explained in Figure 1, the carrier 6
While the cartridge 1 is vertically transferred in the Ya direction to transfer the cartridge 1 from the stocker 2 to the players 4 and 5, or while the carrier 6 is vertically transferred in the Yb direction to transfer the cartridge 1 from the players 4 and 5 to the stocker 2, the reversing plate The A and B sides of the cartridge 1 are reversed by the 180° rotation of the cartridge 18.

At this time, while the carrier 6 is being vertically transferred in the Ya direction or the Yb direction, for example, the A and B sides of the cartridge 1 change from the state shown in FIG. 9B to the state shown in FIG. 9A.
The cartridge 1 which has been reversed by 180 degrees and is held in the cartridge holder 23 is attached to both the support shafts 21 and 22.
When the shutter 39 is reversed to the lower position, one shutter 39 is connected to one first sensor 37 as shown in FIG. 9A.
The first sensor 37 is inserted between the light emitting element and the light receiving element, and a detection output is output from the first sensor 37. Then, one of the second sensors 41 on the lower side shown in FIG. 6 is switched to the operating state. Then, the carrier 6 vertically transferred in the Ya direction or the Yb direction reaches the cartridge supply position of one of the players 4 and 5 shown in FIG. When one of the second sensors 41 detects the detected portion 44 set to
motor 9 is stopped, and carrier 6 is stopped at that position.

However, in this case, one of the second sensors 41
The cartridge holder 23 is flipped to the lower position.
Therefore, when the carrier 6 stops, the cartridge holding part 23 corresponds to the cartridge supply position of either of the players 4 and 5 or the front of the predetermined storage shelf 3 position of the stocker 2. accurately positioned at the specified position.

Note that while the carrier 6 is being vertically transferred in the Ya direction or the Yb direction, the A and B sides of the cartridge 1 are
After being flipped 180 degrees from the state shown in the figure to the state shown in Fig. 9B,
When the cartridge 1 held in the cartridge holding part 23 is reversed to the upper position of both the support shafts 21 and 22, the other shutter 40 is turned over to the light emitting element of the other first sensor 38, as shown in FIG. 9B. and the other first light receiving element.
A detection output is output from the sensor 38, and the other second sensor 42 on the upper side shown in FIG. 6 is switched to the operating state. and Ya direction or Yb
The carrier 6 vertically transferred to the cartridge supply position of either of the players 4 and 5 shown in FIG.
When the position is reached and the other second sensor 42 detects the detected part 44 set at that position, the motor 9 of the carrier transport means 7 is stopped, and the carrier 6 is stopped at that position. .

However, in this case, since the other second sensor 42 is arranged to correspond to the cartridge holding part 23 which has been inverted to the upper position, the cartridge holding part 23 is moved simultaneously with the stop of the carrier 6.
is accurately positioned at a position corresponding to the cartridge supply position of either one of the players 4, 5 or the front of a predetermined storage shelf 3 position of the stocker 2.

As a result of the above, after the carrier 6 has stopped, it is possible to accurately transfer the cartridge 1 to each storage shelf 3 of both players 4, 5 and stocker 2 each time.

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, in the embodiment, a large number of horizontal cartridges were stored vertically in parallel in a vertically long stocker, but the cartridges were erected vertically using a horizontally long stocker. It is also possible to configure the carrier to be stored in parallel to the horizontal direction and 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 mechanism for inserting and removing the cartridge into and out of the cartridge holding portion of the carrier is not limited to the structure using the pair of pull-out claws and the means for transferring the pull-out claws shown in the embodiment, and various other effective mechanisms for taking the cartridge in and out can be used. .

In addition, in the embodiment, the reversing plate is configured to be rotated by a motor in both the Za direction in FIG. 7A and the Zb direction in FIG. 7B, but for example, only one direction (Za direction) is rotated by the motor. It is also possible to drive and return the rotation in the other direction (Zb direction) using the return force of the spring.

Further, in the embodiment, a pair of first sensors and a second sensor are provided.
Although an optical sensor was used as the sensor, mechanical,
Various types of magnetic and photoelectric sensors can be used, and the sensor may be either a contact type or a non-contact type.

[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 allows the cartridge reversing mechanism provided in the carrier to freely invert the A and B sides of the cartridge pulled out from the stocker and supply it to the player.
The player can write and read information on both sides of the disk, A and B, thereby doubling the amount of information in the file.

Moreover, in this case, the reversing mechanism can be made as small as possible, and the carrier can be prevented from increasing in size due to the reversing mechanism, so the carrier can be configured to be small and lightweight, and the carrier can move easily. In addition to reducing the size of the entire disk file device by minimizing the size of the disk file, a small and lightweight carrier can be transported at high speed, and information can be read out at high speed.

In addition, since the reversing mechanism is supported extremely stably, there is no wobbling in the reversing mechanism during transport of the cartridge by the carrier, so that the cartridge can be transported smoothly at high speed.

Furthermore, according to the present invention, it is possible to accurately transfer the cartridge with the A and B sides reversed to each storage shelf of the player and the stocker each time the cartridge is being transferred by the carrier. Control is extremely easy.
