The image information read by the two-dimensional scanning device 11 and supplied via the main controller 1 and the index information created by the main controller 1 are respectively stored in a dedicated storage area of a magnetic tape as a storage medium. It stores (records) sequentially. Numeral 14 is an endless type magnetic chip f (cassette chip f), and a plurality of them are prepared according to the type of image information to be stored, and are appropriately set in the LVR 13. A key date 15 is used to input a unique title and various operation commands corresponding to the image information. Reference numeral 16 denotes an output device such as a cathode ray tube display device (hereinafter referred to as a CRT display device), which outputs image information captured by the two-dimensional scanning device J1 and supplied via the main controller 1, or which is read out from the LVR 13 and outputs image information to the main controller 1.

3. The CRT display device 16 and the hard copy device 17 are connected to the image bus 30, respectively.
Information can now be transferred to each other.

By the way, in such an image information storage and retrieval device,
The magnetic tapes 14 are called files, and each magnetic tape 14 is given a file name depending on the type of image information to be stored. A collection of four or related files among these valley files is called a ')k7-r fileset, and a fileset name is given to this fileset. In other words, a fileset name exists as an upper outline of a file name. On the other hand, the magnetic tape 14 has a large number of layers ll1ll in a direction perpendicular to its running direction.
One image information recording track and several index information recording tracks are formed. Management information and various types of index information are recorded in the index information recording track δ. The management information consists of the file name and file set name that the half-extractable magnetic tape 14 corresponds to, the confidential code, the title structure and title range to define the title condition t set corresponding to the image information, and the new magnetic tape 14. This is recorded in advance by the operator for the key f14. The index information corresponds to each piece of image information, and consists of a title (up to six items) and address information indicating the recording position of the image information. In this case, the address information includes IIJ, which the operator inputs together with the title when storing image information,
It includes bucket size information and document size information based on the document size detection function of the two-dimensional scanning device 11.

Here, we will briefly explain what kind of operation is performed in the above configuration.

First, the original 12 is set on the two-dimensional scanning device 1, and is also set on the magnetic tape J4'i LVRJJ. Then, the title corresponding to the image information of the original 12 and the size of the original 12 are input using the keyboard 15, and a storage operation command is input using the key date 15. Then, the LVRI J operates, and the management information and all index information are read 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 CPU 2 determines whether the management information in the title memory 4 corresponds to the various management information in the floppy disk device jJts, and prohibits storage of image information if this determination is not satisfied.

That is, this determines that the magnetic tape 14 is not compatible with the system of the image information storage device. On the other hand, if the above judgment is satisfied, the CPU
2 determines whether the input title is inconsistent with the titles of various index information in the title memory 4, and when this determination is not satisfied, prohibits the storage 1 of image information. That is, this is to prevent the same title from being recorded on the magnetic tape 14 set in LVRI J. When this determination is satisfied, image information is stored for the first time.

The two-dimensional scanning device 11 operates to read the image information on the document 12, which is 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 the page buffer 5, the image information is read 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 that, page buffer 5 is added again.
The memory makes me sick. The compressed image information in the page buffer 5 is supplied to the LVRJ J via the size conversion circuit 7 and the mask circuit 8, and is placed after the already recorded image information on the image information recording track of the cassette chip 14. It is being recorded. At this time, CPU 2 is
All the recording positions of the image information to be recorded are determined, index information is created using this address information, a title and document size that have been entered manually, and it is added to each of the index information in the title memory 4. After that, the various index information in the title memory 4 is passed through the size conversion circuit 7 and the mask circuit 8 to be stored in the LVR 1.
3 and recorded on the index information recording track of cassette number f14. In this case, various index information recorded on the index information recording track will be updated.

Furthermore, when searching for and reading out desired image information from among the various stored image information, the magnetic tape 14 on which the desired image information is recorded is set in the LVRJ s.

Then, when a search/read operation command is input with the key 13, LVRJ J operates, and the management information and various index information are read from the index information track of the magnetic chip F14, which is transferred to the mask circuit 8 and size conversion. It strikes through the circuit 7 and is stored in the title memory 4 all at once. At this time, when a sorting command is input using the keyboard 15, each piece of index information in the title memory 4 passes through the size conversion circuit 7 and the mask circuit 8 and is displayed on the CRT display device. In this case, a sequence number is attached to each type of index information displayed. The operator then searches for desired image information from among the various index information displayed and inputs the sequence number attached to the index information using the keymate 15. Then, the index information corresponding to this manually determined sequence number is selected, and the required image information is read out from the magnetic chip 14 of the LVRI J based on the index information. The read image information is then stored in the 4-zip 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, that image information is stored in the page buffer 5.
The data is read out from the ROM and supplied to the compression/expansion circuit 6, where it is inversely modified and then stored in the page buffer 5 again. At this time, key 7? - If a recording operation command is input 6 in the code 15, the image information in the page buffer 5 is supplied to the hard copy device 17 via the size conversion circuit 7 and the mask circuit 8, where it is recorded on recording paper. Further, if a display operation command is inputted from the keyboard 15, the image information in the page buffer 5 is transferred to the size conversion circuit 8 and the display interface device W10km to the CRT 7'.
The information is supplied to the display device 16, where it is displayed.

Next, the above-described compression/expansion circuit 6, size conversion circuit 7,
The mask circuit 8 and 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, for example, it is assumed that the storage capacity of the Nova7a 5 corresponds to the image information of an A4 size document.

Therefore, during the image information storage operation, if the original 12 is of 85 size, there will be a portion in the storage area of the page buffer 5 that does not store image information, and therefore the entire storage area of the page buffer 5 will be Image information? If compression processing is performed, even unnecessary image information will be stored in the LVRI JK.

Therefore, the CPU 2 controls the compression operation of the compression/expansion circuit 6 according to the document size information input when storing the image information, and compresses only the image information corresponding to the size B stored in the page buffer 5. I'm trying to process it. FIG. 5 specifically shows the peripheral circuits of the compression/expansion circuit 6 and the page buffer 5. In FIG. That is, 3
Reference numeral 1 denotes 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/9 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. 33

Reference numeral 37 denotes a selection circuit which selects the outputs of the holding sections 35 and 36 in accordance with the size of the document 12 based on the command signal CMD from the CPU 2. A comparison circuit 34 compares the output of the address counter 33 and the output of the selection circuit 37. 38 is an end-of-line detection circuit, and comparison circuit 3
The timing generation circuit 32
It controls the

(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 the CPU 2.

(&) Two-dimensional scanning device during image information storage operation! The image information removed in step 1 and supplied to the page buffer 5 is reduced or struck through. That is, for example, if the storage capacity of the page buffer 5 corresponds to image information of an A4 size original, it is impossible to store B4 size image information in the page buffer 5. Thus, the CPU 2 stores the document size information inputted from the key number ζ-code 15 or the two-dimensional scanning device into the takuji buffer 5.
For example, when the size of the document 12 is B4, the size conversion circuit 7 is operated to reduce the size at a predetermined reduction rate. By doing so, it is not necessary to increase the capacity of the page buffer 5, and it is possible to prevent an increase in cost and an increase in space. Also, C.P.
When the document size information is the same as or smaller than the capacity of the page buffer 5, for example, when the size of the document 12 is A4 or B5, U2 causes the size conversion circuit 7 to perform a strike-through operation (reduction rate °゛0''). , magnification rate ゛0'').

(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 LVRj J to (--the buffer 5) strike through.

(c) When the read image information is recorded by the notebook copying device 17, the image information supplied from the easy-to-read computer 9 buffer 5 to the notebook copying device 17 is enlarged.

Reduce or strike through. That is, the CPU
2 causes the size conversion circuit 7 to perform an enlargement operation or a strike-through operation at a predetermined enlargement rate in accordance with the document size information included in the selected index information while reading the image information.

The enlargement operation in this case is for restoring the image information reduced in the above paragraphs (,) to its original state. Also, CPU
2 C. The size conversion circuit 7 is caused to perform a reduction operation or a strike-through operation at a predetermined reduction rate depending on the size of the recording paper in the hard copy device 17. By doing so, regardless of the size of the recording paper in the notebook copying device 17, it is possible to reliably record one unit of read image information.

(6) The extracted image information is transferred to the CRT display device 1.
6, the image information supplied from the display interface device 10 to the display interface device 10 is reduced or struck through. That is, the CPU 2 causes the size conversion circuit 7 to perform a reduction operation or a strike-through operation at a predetermined reduction rate based on the display capability 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.

(f) Others: When the pattern information taken out from the arm turn generator 9 is supplied to the page buffer 5 and added to the image information in the easy informer 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 signals obtained from the two-dimensional scanning device 11 for each scanning line, or from the page buffer 5 for each line, are The image information signal V to be read out is sequentially shifted and held. And this shift reno star 41, 42, 43, 44, 45
．． The contents of 46 are 6 bits each in the product-sum calculation circuit 4.
7. As shown in FIG. 5, local information of 16 bits (x direction) x 6 lines (y direction) is supplied to the product-sum calculation circuit 47. On the other hand, 48°49 is the distance calculation circuit in the X direction and the distance calculation circuit in the Y direction.
According to the enlargement/reduction ratio setting information supplied from 2, all point position information for the local information of the product-sum calculation circuit 470 is set. Therefore, the product-sum calculation circuit 47 is
When performing the entire reduction operation, weight operation 8 is performed based on point B for local information, as shown in FIG. That is, in Fig. 4, the position of point) B is at a reduction rate of 1/3.
Set the Bi value ``1#'' corresponding to υ, that point), and set that value ``1'' and the distance to each black bit existing around point B (in the vertical direction relative to point B). By setting the distance to the black pit in the horizontal direction to ``1#'', the distance to the black bit in the diagonal direction with respect to point B becomes ``8-''). (weight calculation), and outputs the sum of these products.

Finally, the value output from the product-sum calculation circuit 47 is a local density with emphasis on point B. This local density is then compared with a constant value C in a comparison circuit 50, and a signal corresponding to one bit of a pixel obtained by reducing the local information is outputted from the comparison circuit 50. thus,
Calculations for all local information set for one unit of image information can be performed. In the enlargement operation, one ind is determined according to the enlargement rate, and based on this point, an operation substantially inverse to the above operation is performed.

(3) The mask circuit 8 masks unnecessary portions of image information, and performs the following operations under the control of the CPU 2.

(,) During the image information storage operation, the image information read by the two-dimensional scanning device 11 and supplied to the Danzo buffer 5 is masked according to the input document size information. That is, 2
Since the dimensional scanning device 1 has a constant scanning area regardless of the size of yXXl2, only the area corresponding to the size of the document 12 is used as effective image information, and this allows two-dimensional scanning. Unnecessary images such as dust and scratches on the document table of the mount wtll can be ignored.

In addition, the new image information and the apparent image information (masked part) around it are not stored all at once in the page buffer 5. Even if the page buffer 5 stores old image information, Even if the old image information is added to the new image information, the old image information will not be added to the new image information. Furthermore, by clearing the page buffer 5, there is no need for control to clear the page buffer 5 in advance.

(b) When reading image information, the image information read from the page buffer 5 is masked according to the document size information included in the selected index information, and is supplied to the hard copy device 17 or the display interface 10. In this case, in the hard copy device 17, unnecessary toner is not deposited on the photosensitive drum (not shown);
It is possible to reduce stains on the photosensitive drum.

Then, when the content of the counter 52 becomes 0#, the counter 5
