(They are connected to each other so that information can be transferred to each other. By the way, in such an image information storage and retrieval device,
The magnetic tapes 14 are called files [7]. Each magnetic tape 14 is given a file name 1 to 1 depending on the type of image information to be stored. 1. Among these files, a collection of files that are of the same type or are related is called a file set. / This fileset is given a fileset name. A file set name exists as a concept at the -L position of a file name. On the other hand, a large number of image information recording tracks and several index information recording tracks are formed on the magnetic tape 14 in a direction perpendicular to its running direction. Management information and each food index information are recorded in the memo index information recording trunk. The management information includes the file name and file set name that the magnetic tape 14 corresponds to, a secret code, a title structure and a title range for defining title conditions set corresponding to the image information, and includes 14, [7] is recorded in advance by the wave generator. The index information corresponds to each piece of image information, and consists of a title (maximum of 6 items) and address information indicating the recording position of the image information. In this case, the address information includes information about the document size 1 that the operator inputs together with the title when storing image information, or document size information based on the document size detection function of the two-dimensional scanning device 11. Here, -to d own story 811 he dopi)
, I will briefly explain how these actions are performed. First, the original 12 is set in the two-dimensional scanning device [IZ], and the magnetic tape Z4 is set in the LVRI 3. Then, the title and Ig corresponding to the image information of the original 12 and the size of the original I2 are entered manually using the keyboard 15, and a storage operation command is input using a portion of the keys I5. Then, the LVRI 3 operates, and the management information and all index information are read out from the index information recording track of the magnetic tape 14 and stored in the title memory 4 all at once. At this time, the CPIT 2 determines whether the management information in the title memory 4 corresponds to the various management information in the floppy disk drive 5, and prohibits storage of image information if this determination is not satisfied. That is, it is determined that the magnetic tape I4 is not compatible with the system of the image information storage and retrieval device. On the other hand, if the above judgment is satisfied, the title entered by CPU 2 will be displayed as title 4.
It is determined whether the title of each rod index information in the table matches the title, and if this determination is not satisfied, storage of the image information is prohibited. That is, this is to prevent the same title from being recorded on the magnetic tape 14 inserted into the LVR 13. When this determination is satisfied, image information is stored for the first time. [2] Then, the two-dimensional scanning device 11 operates and scans the original 12-
The image information of HI is read and stored in the page buffer 5 via the mask circuit 8 and the size conversion circuit 7. When one unit of image information is stored in this page buffer 5, the image information is taken out from the page buffer 5 and supplied to the compression/expansion circuit 6, where it is compressed using the well-known Modify-Hoffman transformation. After a while, the data is stored in the page buffer 5 again. And this page buffer 5
The compressed image information in the cassette tape 14 is supplied to the LVR 13 via the size conversion circuit 7 and the mask circuit 8, and is recorded after the already recorded image information in the image information recording trunk of the cassette tape 14. At this time, the CPU 2 determines the recording location of the image information to be recorded, creates index information using this address information, the title and document size input in advance, and
It is added to the management information and each index information in the title memory 4. ] After 7, title memory 4
The f.theta. index information and name index information in the cassette tape 14 are supplied to the LVR 13 after passing through the reproduction converter circuit 7 and the 7-7 screen circuit 8, and are recorded on the index information recording track of the cassette tape 14. In this case, the tube filling information and each glaze index (H report) recorded in the index information recording track will be updated. Also, the required image information can be searched from among the various stored image information. When starting, set the magnetic tape 14 on which the required image information has been recorded into the LVR 13. Then, when a search/read operation command is input using the keyboard IS, the LVRI J operates and the index information of the magnetic tape fr4 is input. Kankon Yu @mo and each glaze index information are extracted from the track, and they strike through the mask circuit 8 and size conversion circuit 7 to the title memory 4.

~ and input the sequence number attached to the index information using the - key I5. Then, index information corresponding to this input sequence number is selected, and LVRI J
Required image information is output from the magnetic tape 14 of d. The read image information is then stored in the R-soba sofa 5 via the mask circuit 8 and the size conversion circuit 7. When one prefecture's worth of image information is written in this page buffer 5, the image information is compressed from the Soba Sofa 5 and supplied to the compression/expansion circuit 6, where it is inversely converted into mode. Then, 1"] and (-3 stored in the Soba Sofa 5. At this time, if a recording operation command is input using the keyboard 15, the image information d in the page buffer 5, the size conversion circuit 7 and the mask circuit 8 are ) - supplied to the Tocobee device 17, where it is recorded on recording paper. However, if the display operation command is input on the keyboard 15,
The image information in the page buffer 5 is supplied via the size conversion circuit 7, the mask circuit 8, and the display interface device 10 to the CRT display device 16, where it is displayed. Next, the above (~) compression/expansion circuit 6, size conversion circuit 7
, the mask circuit 8, and the display interface device @10 will be explained in detail. (1) The compression/expansion circuit 6 mainly performs the compression/expansion operations described above, but also has the following functions based on the control of the CPU 2. That is, let us assume, for example, that the storage capacity of the couch 5 corresponds to the image information of an A4 size document. 17 During image information storage operation, if the document 12 is of B5 size, there will be a portion in the storage area of the i4 buffer 5 that does not store image information. If the image information in all of the storage areas No. 5 is compressed, unnecessary image information will be stored in the LVR 73. Therefore, the CPU 2 controls the compression operation of the compression/expansion circuit 6 according to the input document size information when storing the image information, and controls the compression operation of the compression/expansion circuit 6 to
Only image information corresponding to the size is compressed. FIG. 5 specifically shows the compression/expansion circuit 6 and the peripheral circuits of the page buffer 5. In FIG. That is, 3 is a line buffer, which temporarily stores image information for each line read from the page buffer 5 or image information to be stored in the page buffer 5 for each line. A timing generation circuit 32 generates a data clock signal corresponding to a pixel of image information and a line clock signal corresponding to each line. 5sl-J address counter, line pad Noah 3Z
This is only for specifying one effective area for image information within. ,95,. 96 is a holding unit for document size information;
For example, A4 size information and B5 size information are held. 374- is a selection circuit, and a command signal C from CPU2 is selected.
The above holding section, depending on the size of the original document No. 2 based on the MD,?
5 and 36 outputs are selected. A comparison circuit 34 compares the output of the address counter 33 and the output of the L selection circuit 37. 35 is enP op line detection 1 [
] In one path, the timing generation circuit 32 adjusts the timing φ11 according to the comparison result of the comparison circuit 34 and the like. (2) The size conversion circuit 7 has an enlargement operation mode, a reduction operation mode, and a strike-through operation mode, and performs the following operations according to the control of CP[, J2. (a) During the image information storage operation, the image information that is scanned by the two-dimensional scanning device 11 and supplied to the page buffer 5 is reduced or struck through. That is, for example, if the storage capacity of the Zipanofa 5 corresponds to the image information of an A4-sized document, it is impossible to store B4-sized image information in the sofa 5 for each page. 17, when the document size information input from (':r'Tr 2, keyboard 5 or 2D scanning device W1) is larger than the volume of the sofa 5, for example, the document 12 When the size of is B4,
The size conversion circuit 7 is operated to perform a reduction operation at a predetermined reduction rate. By doing so, it is not necessary to make the page buffer 5 large-capacity, and it is possible to prevent an increase in cost and an increase in waveform. When the original size information is equal to or smaller than the capacity of the page buffer 5, for example, if the size of the original 12 is A4 or B5, the CPU 2
At this time, the size conversion circuit 7 is caused to perform a strike-through operation (reduction ratio '0#, enlargement ratio '()#). (b) At the time of image information storage operation and image information readout,
The image information supplied from the page buffer 5 to the LVR 13 and the image information supplied from the LVR 1j to the page/sofa 5 are struck through. (C) When the output image information is recorded by the notebook device 17, (-) the image information supplied from the first buffer 5 to the notebook device 17 is enlarged. Shrink again and strike through the soil. That is, CPt
J2 enlarges the size conversion circuit 7 at a predetermined enlargement rate according to the document size information included in the index information selected when reading image information;
Make the strike through work. The enlargement operation in this case is the ninth one that returns the image information reduced in item (1) to its original state. Ota, CP
U2F! , The enlarging/reducing circuit 7 is caused to perform a reduction operation or a strike-through operation at a predetermined reduction ratio depending on the size of recording paper in the hard copy device @I'r. By doing so, regardless of the size of the recording paper in the notebook device 17, it is possible to reliably record one unit of read image information. (d) When displaying the id-outputted song encyclopedia information on the CRT display device 16, the image information supplied from the page buffer 5 to the display interface device 10 is struck through by the amount of reduction 'jr. That is, CP[J
2 &J, the size conversion circuit 7 is caused to perform a reduction operation or a strike-through operation at a predetermined reduction rate based on the display capacity of the CRT display device 16 stored in advance. By doing so, it is not necessary to make the CRT display device large and high-performance, and an increase in cost can be prevented. However, in this case, it is also possible to operate the size conversion circuit 7 by an operator's operation, and the display contents can be made easier to see. (,) In addition, when the pattern information taken out from the pattern generator 9 is supplied 17 to the page buffer 5 and added to the image information in the page buffer 5, strike-through is performed. FIG. 4 shows the size conversion circuit 7. 41, 42, 43, 44, and 45, 46 are shift registers of, for example, 2048 bits, and the image information signal (2) obtained for each scanning line of the two-dimensional scanning device 11 or read out from the page buffer 5 for each gain. The image information signal (2) is sequentially shifted and held. And this shift register 41, 42, 43, 44, 45
．． The contents of 46 are 6 bits each in the product-sum calculation circuit 4.
7. That is, as shown in FIG. 5, local information of 6 bits (X direction) x 6 lines (Y direction) is supplied to the product-sum calculation circuit 47. On the other hand, 48°49 is an X-direction distance calculation circuit and a Y-direction distance calculation circuit, and the CPU
According to the enlargement/reduction ratio setting information supplied from 2, the point position information for the local information of the above-mentioned "sum-of-products operation" circuit 470 is set. , weight calculation is performed based on the point )H for local information as shown in FIG. 5. That is, in FIG.

By doing so, take the product (width calculation) of the point l-'11 and the reciprocal of 1. (the distance to the black pit l- in the diagonal direction is 'f'), and calculate these products. Outputs the summed value. In other words, the value output from the product-sum calculation circuit 47 is [
, i-bind B is the local concentration. Then, this local density is compared with a constant value C in a comparison circuit 5o, and the local information is reduced from the comparison circuit 5θ]
A signal corresponding to one bit of a pixel consisting of 7 is output. In this way, the calculation γ for all the local information set for one unit of image information is performed. In the enlargement operation, a point is determined according to the enlargement ratio, and based on this point, an operation substantially inverse to the above-mentioned operation is performed. (3) The mask circuit 811 masks unnecessary portions of image information and performs the following operations under the control of the CPU 2. The image information supplied to the page buffer 5 is masked according to the input document size information.In other words, since the two-dimensional scanning device 11 has a constant scanning area regardless of the size of the document 12, Manuscript I2
Only the area corresponding to the size of fl! is considered as valid image information, and this allows the two-dimensional scanning device fl! 711, it is possible to ignore unpleasant images such as dust and scratches on the document table. In addition, the new image information and the appearance of the surrounding area - L's image information (masked part) will be stored all at once, so even if the old image information is stored in the page buffer 5. Even if you admire yourself, the old image information will not be added to the new image information.Moreover, by doing this (-Soba Sofa 5
The control required to clear the problem in advance becomes a concern. (b) At the time of the image information signal, the image information read from the page/text file 5 is masked according to the document size information included in the selected index information, and sent to the hard copy device #17 or the display interface 10. supply In this case, in the hard copy device 17, unnecessary toner does not adhere to the photosensitive drum (not shown), and the drum becomes less dirty.
