RAM (Random Access Memory).

FIG. 3 schematically shows the cassette tape and its feeding mechanism of the magnetic tape device 9. A fixed reel 22 that does not rotate is provided in the case 21, and this reel 22 has a width of, for example, 1. /2
A magnetic tape 23 measuring inches (about 12.7 mm) and having a length of about 36 m is endlessly wound. and,
When the cassette tape configured as described above is loaded, the innermost portion of the tape 23 wound around the reel 22 passes through the window 22a provided in the reel 22.
After being pulled out from the tape 23 and sent at high speed (approximately 5 m/sec) in the direction of the arrow a in the figure by the capstan 24 and the pinch roller 25, it is rewound again to the outermost portion of the tape 23. Therefore, the tape 23 rotates once in approximately 7.2 seconds. As shown in FIG. 4, one rotation of the tape 23 is confirmed by optically detecting a tape mark 26 made of silver paper or the like affixed to the connecting portion 23a of the tape 23 with a mark detector 27. ing. The output signal of the detector 27 is also used as a reference for detecting the position of a block on the tape 23 (described later). As shown in FIG. 4, 200 recording tracks 28 (track width approximately 40 .mu.m, inter-track pitch approximately 52 .mu.m) are set on the tape 23 in parallel along its running direction a, as shown in FIG. Here, the recording tracks 28 are sequentially assigned track numbers "0, 1, 2, ... 198, 199" starting from the lowest track, and the two tracks located approximately in the center (track numbers "99, 199") 100" and the track number "99" is a spare track) is a unique search title (consisting of a search code and a record address, and the record address consists of a track number and a block number) corresponding to one unit of image information. The remaining ₁₉₈ tracks (track numbers "0-98, 101-199") are information recording tracks ₂₈₂ for recording image information. Each recording track 28 is divided into 256 blocks in the length direction of the tape, as shown in FIG. 4, and each block has tape marks 2.
Sequentially "0, 1, 2,...254, 255" with 6 as the standard
and a block number are assigned. In order to record or reproduce information signals on the tape 23, a recording/reproducing head (a two-gap magnetic head with an erasing function) 29 provided near the capstan 24 is moved in the running direction a by a head access mechanism (not shown). This is done by reciprocating in micron units in the orthogonal direction b and selecting an arbitrary recording track 28.

FIG. 5a shows the recording format of each search title in the search title recording track ₂₈₁ , showing the search code recording area in which the search code is recorded, the track number in which the image information corresponding to this search code is recorded, and A recording address recording area where the recording address with the block number is recorded, an image length recording area where the length of the image information, that is, the number of data blocks indicating how many blocks it spans, is recorded, and it corresponds to the above search code. Deletion code recording areas are recorded in order, in which deletion codes indicating whether or not the image information to be deleted are to be deleted. Further, FIG. 5b shows the recording format of each image information on the information recording track ₂₈₂ , in which image information is recorded over a plurality of blocks.

Next, a description will be given of how image information registration (storage) and retrieval using this invention method are performed. First, let's start with the 6th section regarding image information registration.
To explain with reference to the flowchart shown in the figure,
The user selects and sets the registration mode using the keyboard 2, inputs a search code for image information to be registered, and presses the start key 30. This results in
The CPU 15 checks the validity of the input data based on the number of digits, character type, etc. according to the format of the predefined search code (cyclic redundancy check).
CRC) and already registered search codes are checked to see if there is any double registration.If the search code is correct as a result of these checks, it is stored in the RAM 16. Then, when the document is set in the two-dimensional scanning device 6 and the start key 30 is turned on, the CPU 15 operates the two-dimensional scanning device 6 and the magnetic tape 23. The two-dimensional scanning device 6 two-dimensionally scans image information such as a set document and performs photoelectric conversion. This photoelectrically converted line information is sequentially stored in the page buffer 11. When one page of image information is stored in the page buffer 11, the image information is stored in the refresh memory 14 and displayed on the display device 7.

This allows the operator to use the display to check whether the original is skewed or folded, or whether the shading of the original matches the binarization level of the two-dimensional scanning device 6, thereby producing a satisfactory image. If not obtained, the discard key 31 is inserted. Then, CPU15 has page buffer 11
and erase the contents of the refresh memory 14. If the original is bent or folded, the original is reset, and if there is a problem with shading, the binary level of the two-dimensional scanning device is adjusted and the original is set again, and the same operation as described above is performed. By the way, display device 7
If the displayed image is satisfactory, the record key 32 is turned on. Then, the CPU 15 performs band compression on each unit of image information stored in the page buffer 11 using the well-known MH (Modified Hoffmann) conversion in the compression/expansion circuit 12.
The compressed line information is supplied to the head 29 of the magnetic tape device 9. Thereby, the head 29 records the supplied image information on the corresponding information recording track ₂₈₂ . When the recording of this image information is completed, the CPU 15 reads out the recorded image information (compressed information), decompresses it by inverse MH conversion in the compression/decompression circuit 12 for each scanning line, and supplies the expanded line information to the page buffer 11. do. When the reproduced image information for one page is stored in the page buffer 11, the image information is stored in the refresh memory 14 and displayed on the display device 7. Also, at this time, the CPU 15 stores in the RAM 16 the track number on which the image information is recorded, the start block, and the length of the image in correspondence with the search code.

Thereby, the operator can check whether the image information has been recorded by the display, and if a satisfactory image is not obtained, a deletion operation is performed by pressing the deletion key 34. Further, if a satisfactory image is obtained by the above check, the confirmation key 33 is pressed. Then, CPU15
The search title stored in the RAM 16 is supplied to the head 29 of the magnetic tape device 9. As a result, the head 29 records the supplied search title, ie, search code, track number, starting block number, image length, etc., in the corresponding search title recording track 2.
8 Record in ₁ .

Next, it is assumed that a plurality of manuscripts are registered in succession while the above-described registration is being performed.
Now, on the keyboard 2, the continuous mode for continuous recording and the registration mode are selected and set, and the search codes to be registered are sequentially input. Then, the CPU 15 sequentially accepts the input search codes and stores them in the RAM 16. Next, the CPU
15 checks whether the input of the search code has been completed, and when the input has been completed, the first input search code is read from the RAM 16, is converted into a character pattern by the pattern generator 13, and is stored in the pattern register 11. supply to. The first input search code stored in the pattern register 11 is displayed on the display device 7. This results in
The operator sets the document corresponding to the displayed search code on the two-dimensional scanning device 6. From then on,
The registration operation is performed and the image information is recorded on the tape 23 of the magnetic tape device 9. When the recording is completed, the CPU 15 displays the next input search code on the display device 7. As a result, the operator sets the corresponding document on the two-dimensional scanning device 6, and its image information is recorded. In this way,
When the recording of the above multiple manuscripts is completed,
The CPU 15 supplies a plurality of search titles stored in the RAM 16 to the head 29 of the magnetic tape device 9. As a result, the head 29 records the supplied search title in the search title recording track ₂₈₁ .

Further, a continuous mode for continuous recording and a registration mode are selected and set using the keyboard 2, and a plurality of documents are sequentially set in the two-dimensional scanning device 6. Thereby, recording of the original set in the two-dimensional scanning device 6 is performed in the same manner as the registration operation. Then, it is checked whether or not the recording of the plurality of manuscripts has been completed, and when the recording is completed, the first recorded image information is reproduced from the magnetic tape 13, stored in the page buffer 11, and displayed on the display device 7. . Thereby, the operator inputs a search code corresponding to the image information using the keyboard 2. Then, the CPU 15 stores the search code, the track number on which the image information is recorded, the block start number, and the length of the image in the RAM 16. When the storage is completed, the CPU 15 reproduces the next recorded image information and displays it on the display device 7. As a result, when the operator inputs the corresponding search code using the keyboard 2, the CPU 15
A search title such as a search code is stored in the RAM 16. In this way, when the search titles for the plurality of manuscripts are stored in the RAM 16, the CPU 15 records these search titles using the head 29.

Next, the search and playback output of the image information stored (registered) as described above will be explained. First, select and set the search mode from keyboard 2, and enter the search code and start key 3.
Enter 0. Then, CPU 15 uses tape 23
At the same time, the head 29 is moved to the search title recording track ₂₈₁ , and playback of that track is started. As a result, all reproduced search titles, that is, search codes, and recording addresses indicating the track number and start block number of the corresponding image information are stored in the RAM 16. Then, the CPU 15 sequentially compares and collates the search code in the search title stored in the RAM 16 with the input search code, and checks whether there is a search code that matches the input search code. As a result of this check, if there is no search code that matches the required search code, an error message is displayed indicating that the search is not possible and the search operation is terminated. On the other hand, if a search code matching the required search code exists, the track number and block number added to the matching search code are searched from within the search title stored in the RAM 16. Then, the CPU 15 moves the head 29 to the information recording track ₂₈₂ corresponding to that track number and starts reproducing that track. Then, the CPU 15 transfers the image information (compressed information) to the compression/decompression circuit 12 for each scanning line.
By supplying the image information to page buffer 11, the band is expanded by MH inverse transformation and the original image information is transferred to page buffer 11.
sequentially supplied to In this way, page buffer 11
When all the image information for one page reproduced is stored, the CPU 15 supplies the image information to the refresh memory 14 and displays it on the display device 7. As a result, when the operator determines that something should be printed, he or she presses the print key 35. Then, the CPU 15 supplies the image information of the page buffer 11 to the recording device 8, and the hard copy 1
Obtain recording output as 0.

Further, when another search code is input, the same operation as described above is performed to obtain the hard copy 10 of the corresponding image information.

In the above embodiment, a case has been described in which the present invention is applied to a magnetic tape device that records or reproduces image information such as documents, but the present invention can be similarly implemented in a magnetic tape device that records or reproduces other information. In addition, although we have described the case where the implementation is applied to a magnetic tape device that uses endless magnetic tape as a storage medium, for example, a magnetic tape device that uses a normal magnetic tape that is not endless, a magnetic disk device that uses a magnetic disk as a storage medium, and even a storage device. The present invention can be similarly implemented in other similar information storage devices such as optical disk devices that use optical disks as media.

As detailed above, according to the present invention, it is possible to separate the operation of inputting a search code and the operation of storing image information, thereby simplifying the operation and improving the storage speed of image information. An input device in the device can be provided.
