It is necessary to sequentially turn over the plate-shaped recording medium and find it while reading the label. Therefore, the search is troublesome and takes a lot of time, and since the search is aimed at the plate-shaped recording medium, there is a risk of bending and damaging the plate-shaped recording medium. There was a drawback that there was.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks, to provide a retrieval device which can easily retrieve a desired one from among a large number of plate-shaped recording media in a short time, and which is free from the possibility of damaging the plate-shaped recording media. In order to achieve this object, the present invention sequentially stores plate-shaped recording media in storage sections of a storage box, provides display elements corresponding to these storage sections, and displays large-sized storage media. The file names of the plate-shaped recording medium are stored in the order in which they are stored, and when a desired file name is input, n'i is searched from the memorized nfc file name, the corresponding display element is driven, and the plate-shaped recording medium is The present invention is characterized in that the stored contents are modified in accordance with changes in the storage arrangement of recording media.

The present invention will be described below based on the illustrated embodiments. FIG. 1 is a schematic diagram of a floppy disk search device according to an embodiment of the present invention. In the figure, 1 is a storage box for storing recorded floppy disks, and 2 is a large control device that searches for a desired one of the n+ floppy disks stored in storage box 1. The control device 2 is a keyboard 2a
, a display section 2b, etc., the details of which will be described later.

FIG. 2 is a perspective view of the storage box shown in FIG. 1.

In the figure, 3 is a case for storing floppy disks, and the storage box 1 is used to store recorded floppy disks.
Stored in. 4 is a holding plate that presses the case 3 at the -left end (left end in Fig. 2) of the case 3; 5 is a space between one side wall of the storage box 1 (left side wall in Fig. 2) and the holding plate 4; It is a spring mounted on. By pressing the holding plate 4 with the spring 5, the case 3 on the left end is pushed to the right.As a result, all the cases 3 stored in the storage box 1 are pushed toward the right side wall of the storage box 1. They are arranged in order from the right side wall to the left without any gaps. This arrangement is always maintained ζn. Therefore, in the portion of the storage box 1 where the cases 3 are present, a storage section corresponding to the volume of the case 3 is formed for each case 3. 6 is a floppy disk insertion guide fixed at a predetermined position facing the front of the storage case L, and the necessary information is recorded on the new 6.
Insert the case 3 into which a used floppy disk or a used floppy disk is stored, through the groove 6a of the insertion guide 6, into the left side of the leftmost case 3 in the storage box 1 against the spring force of the spring 5. .

7 is an n+ motor provided separately from storage box 1, and 8 is motor 7.
9 is a shaft holder fixed to the storage box l and into which the n1 shaft 8 is inserted. The shaft 8 is formed with a spiral thread, and the shaft holder 9 is formed with a groove that matches this thread. Then, when the motor 7 is driven and the shaft 8 rotates, the storage box 1-1) is moved in the direction of rotation.
Move left or right. Reference numerals 10a and 10b are two optical sensors (only one optical sensor 10a is shown in the figure) that are provided facing the back surface of the storage box 1 and control the drive of the motor 7. The position coincides with the position facing the groove 6a of the insertion guide 6. Reference numeral 11 denotes an n-sized display element provided at the upper front surface of the storage box 1. The display element 6 is arranged in a one-to-one correspondence with the storage section formed by the case 3. That is, when the case 3 is stored in the storage box l, fL,7<, the display element 11 corresponding to kneading is always disposed at the storage position of the case 3. The display element 11 uses a light emitting element such as a light emitting diode or a small lamp.

Next, the operation of this embodiment will be explained with reference to FIGS. 3 and 4. As shown in FIG.
Insert into. At this time, a title (hereinafter referred to as file name) representing the recorded contents of the floppy disk 3 is pasted at an appropriate location on the case 3. With the file name pasted ζf'1, the case 3 is inserted into the storage box 1 through the groove 6a of the insertion guide 6.

FIG. 4 is a plan view when case 3' (e-storage box lK) is stored.Currently, among the cases 3 stored in storage box 1, the leftmost case 3 is moved to case 3n, and one of them is The case on the right is Case 3n-□, the case on the right of Case 3n-□ is Case 3n-2, and the case 3 stored in Shinra Roku is Case 3n+. Also, storage box 1 is Case 3n+. It is assumed that the left side edge of the case 3n almost coincides with the right side wall of the groove 6a of the insertion guide 6, and the case 3n is in front of the optical sensor 10b. When the case 3 is present in front of the case 3, the light from the light source is reflected and the light receiving element receives the reflected light to generate an output, and when the case 3 is not present in the front, the light from the light source is not reflected. If an output signal is generated only from the optical sensor 10a, the motor 7 is not driven and the optical sensor lOa, 1
If neither of the optical sensors 10a or 10b generates an output signal, the motor 7 is driven in the rotational direction to move the storage box 1 to the right. If both the optical sensors 10a and 10b generate output signals, the motor 7 moves to the right side of the storage box 1. is driven in a rotational direction that moves it to the left.

- Now, when the recording on the floppy disk 13 is completed, this jacket 1 is stored in the jacket 12.
2 is entered in case 3n+□, and the Sial name is pasted on case 3 of n et n1. As shown in FIG.
The storage box I V is forcibly moved from the front gap S of the presser plate 4 to the left against the spring force of the spring 5.
C storage area. Case 3n+ is pressed to the right by the spring force of spring 5 via the holding plate 4, and is in contact with case 3nK'J, and is stored in storage box 1.
are held in n storage sections, respectively.

The optical sensor 10a is inserted into the groove 6a of the insertion guide 6 as described above.
When the case 3n+ is placed in the storage box 1, the case 3n+ is placed in front of the optical sensor 10a. Then, the original sensor 10a generates an output signal, and both optical sensors loa,
10b will also generate an output signal. Therefore, the motor 7 is driven and the storage box l moves to the right. Due to the movement of storage box l to the right, case 3n+ has optical sensor lO.
Case 3 is located in front of optical sensor 10a.
ceases to exist. In this state, the drive of the motor 7 is stopped, and the storage box 1 is placed in a position where the next case 3 can be stored via the insertion guide 6.

Next, among the six cases 3 stored in the storage case 3, put the floppy disk 13 necessary for playback into the six cases 3'f.
: The operation of the storage box 1 when taken out will be described. When a desired case 3 is taken out from the storage box l, each case 3 on the left side of the case is moved to the case 1 by the spring force of the spring 5.
Move to the right by an amount. Here, if the case 3n is at the left end position, when the desired case 3 is taken out, the case 3n moves to the position of the case 3n-1 to the right. Therefore, the case 3 no longer exists in front of the optical sensor 10b. As a result, the optical sensor 10'b does not generate an output signal, and both optical sensors 10a and 10b do not generate an output signal, and the motor 7 is driven to move leftward into the storage box 1'. When the storage box 1 is moved to the left, the case 3n is positioned in front of the optical sensor 10b, and the optical sensor 10b generates an output signal and the drive of the motor 7 is stopped. The movement of the n1 storage box 1 to the left is also stopped.

At this time, the storage box 1 is in a position where the next case 3 can be stored via the insertion guide 6. In this way, as the cases 3 are stored and taken out, the storage box 1 moves by one storage section to the right or left, and the cases 3 in the storage box 1 are arranged in order from the right side in each storage section without any gaps. Sanru.

Next, a description will be given of the control device 2 and its operation for instructing the desired case 3 to be stored in the storage box IK f17' from among a large number of cases 3.

FIG. 5 is a block diagram of the control device shown in FIG. 1. In the figure, 2a + 2b + 11 is the same as the above-mentioned 2a.
2d is a CPU (central processing unit) that performs necessary calculations and control, 2f is a ROM (read-only memory) that stores all the processing procedures of CPU 2d, and 2g is each Storage position (storage category) where case 3 is stored, file name of each case 3, RAM (random medium access memory) that stores input large signals and calculation results, 2h is calculation and control This is an output section that outputs the value obtained.

FIGS. 6(a) and 6(b) are layout diagrams of the storage contents of the RAM 2g. Now, each address of the temporary KRAM 2g and each storage position of storage box 1 are set such that address 1 is the first position (rightmost position), 2
It is assumed that the address is associated with the second position, and the N address is associated with the iN position.

Therefore, when storing the case 3 in the storage box 1, if you operate the keyboard 2a and check the file name of the case 3 on the display 2b, the file name of the case 3 can be stored in the RAM 2gK in order. As shown in Figure (a), address 1 (first storage location) K file name BMCALC, address 2 (second storage location)
Storage location) file name 0UTP,...
...The file name ZZP may be stored at address N (Nth storage position), but this storage position and file name actually match the storage status of case 3 stored in storage box 1. be.

Now, when case 3 is stored in the same arrangement as the memory contents shown in storage box IK Fig. 6 (a), the file name CTRP
Suppose that it becomes necessary to take out the floppy disk 13 and play it. Operate keyboard 2a to select file name CT
When the RP is output (confirmed on the display section 2b), a signal corresponding to this is sent to the CPU 2. Incorporated into d
, according to the processing procedure stored in ROM2f,
Import t″L large file name CTRP and RAM 2g 1
The file names stored at address 2, . . . are sequentially compared. This comparison yields a match down to address 5. Therefore, it is determined that the storage position of the case with the required file name CTRP is at the 87!5 storage position, and the result is output to the display element 11 from the output section 2h. That is, corresponding to the fifth storage position from the output section 2h, five of the display elements 11 from the right side are
The th display element 11 emits light. The above operation can be performed in an extremely short time, so use keyboard 2a to enter the file name CT.
Immediately after the RP is implanted, the display element 11 emits light. Therefore, it is possible to remove the desired floppy disk 13 in a short time without having to search for each file name one by one.

When the case 3 in the 5th storage position causes the display element 110 to emit light and then takes it out, the 7A5 storage position IFt-I
τ1 left from t-! As described above, the case 3 at position 1 is moved to the right by one storage section by the spring force of the spring 5, and the case 3 is moved to the left in preparation for storage of the next case 3.

On the other hand, the memory contents of RAM2g are stored in ROM2f.
In accordance with the above processing procedure, the file name stored at each address after address 6 is moved up by one address and changed to the content that is not to be stored. The changed NFC storage contents are shown in FIG. 6(b). That is, the file name NAP that was previously stored at address 6 is now stored at address 5,
The file name PQP stored at address 7 is stored at address 6. The file name ZZP stored at address N is stored at address N-1. n, N
The address becomes a vacant address.

The change in the stored contents may be executed only when, for example, the output signals from both optical sensors 10a and 10b disappear. The stored contents shown in FIG. 6(b) match the storage state of each case 3 in the storage box 1 after the case 3 with the file name CTRP is removed.

When the playback of the floppy disk 13 with the file name CTRP is finished and the case 3 is stored in the storage box l again,
Keyboard 2a' (il-operate to enter file name CTRP
When instructed to store the file name CTRP, the file name is stored in the RAM2g at the address next to the last address where the file name is stored.
is memorized. That is, the file name CTRP will be stored at address N. On the other hand, after the operation using the keyboard 2a is completed, the case 3 with the file name CTRP is stored in the storage box 1 from the insertion guide 6 against the spring force of the spring 5 as described above. And this file name CTRP
The stored state of each case 3 in the storage box 1 after the cases 3 have been stored matches the contents stored in the memory type fL6 in the RAM 2g.

In the above description, an example is described in which an optical sensor is used to control the drive of the motor. However, the optical sensor may be limited to a laser sensor, a magnetic sensor, or other type of sensor.

Furthermore, instead of rotating the shaft, the movement of the endless belt can be used to move the storage box.

Furthermore, the insertion guide and the sensor can be moved together when the storage box is moved.

In this way, in the non-implemented example, a floppy disk is inserted, the six cases are pushed to one side of the storage box by the spring, and placed without any gaps, and the sensor detects the insertion and removal of the case. The storage box is moved accordingly, and a display element is provided corresponding to the storage position of the case, and the RA in the control device is
M stores all the file names in the order in which the cases are stored in the storage box, and when a desired case is extracted, the control device searches for the storage position of that case and displays the corresponding display element. In addition, the storage contents of the DRAM can be modified by changing the storage position of the case, so that the desired floppy disk can be easily retrieved in a short time without having to insert the floppy disk. Furthermore, when storing a floppy disk, there is no need to consider its storage position, so it can be easily stored. It goes without saying that the present invention can also be applied to other plate-shaped recording media. Further, the case does not necessarily have to be a rigid body, and may be flexible to some extent. Furthermore, it may be a jacket without using a case.

Furthermore, the file name is converted into a barcode and affixed to the case, jacket, or plate-like record body, while a light source and optical sensor are placed on the wall of the insertion guide, and the file is stored through the insertion guide. It is possible to omit the trouble of inputting the file name of the plate-shaped recording medium each time using the keyboard. The same effect can be obtained by using a magnetic stripe instead of the bar code, and a magnetic head instead of the light source and optical sensor. In this case, if an erasing head is provided, the file name can be erased as needed. In addition, the display element is not necessarily limited to a light emitting body, and various display elements can be used, and the display form can also be varied, such as activation or non-operation of only the display element, continuous operation or intermittent operation, color change, etc. It is possible to adopt any form.

As described above, in the present invention, display elements are provided in the storage box corresponding to the storage sections, and the plate-shaped recording media are sequentially stored in the storage sections. A desired file name is searched from the memory, a display element corresponding to the search result is driven, and the stored contents are modified in accordance with changes in the storage arrangement of the plate-shaped recording medium. Because of this, a desired plate-shaped recording medium can be easily removed in a short time without damaging the plate-shaped recording medium. Furthermore, when storing a plate-shaped recording medium, there is no need to consider its storage position, so storage can be easily carried out.
