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 receives image information read by the two-dimensional scanning device 11 and supplied via the main control device 1, or read from the LVRJ J and sent to the main control device.

The display device 16 and the hard copy device 17 are each connected to the image path 21 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, and each magnetic tape 14 is given a file name depending on the type of image information to be stored. A collection of files of the same type or related to each other is called a file set, and a file set name is given to this file set. In other words, a fileset name exists as a superordinate concept of a file name. On the other hand, the magnetic tape 14 has
A large number of image information recording tracks and several index information recording tracks are formed in a direction perpendicular to the traveling direction. Management information and various index information are recorded on the index information recording track. 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 accounting for the title conditions set corresponding to the image information, and includes 14 is recorded in advance. 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 document size information that the oirator 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, we will briefly explain what kind of operation is performed in the above configuration.

First, the original 12 is placed in the two-dimensional scanning device 11, and the magnetic tape 14 is placed in the LVR 13. 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 keyboard 15. Then,
The LVRs 1 and v operate, and 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 5, and prohibits storage of image information if this determination is not satisfied. That is, this is to determine that the magnetic tape 14 is not compatible with the system of the image information storage and retrieval device. on the other hand,
When the above determination is satisfied, the CPU 2 determines whether the input title is inconsistent with the title of various index information in the title memory 4, and when this determination is not satisfied, storage of image information is prohibited. That is, this is
This is to prevent the same tie (/l/) from being recorded on the magnetic tape 14 set in the LVR 1B. 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 original 12, which is stored in the R-Zipuffer 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.
is memorized. Then, the compressed image information in the page buffer 5 is supplied to the LVRJ 3 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 tape 14. It will be recorded.

At this time, the CPU 2 determines the recording position 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 various index information in the title memory 4. After that, the management information and various index information in the title memory 4 are passed through the size conversion circuit 7 and the mask circuit 8 and sent to the LVR.
13 and recorded on the index information recording track of the cassette tape 14. In this case, the management information and 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 types of image information stored, the magnetic tape 14 on which the desired image information is recorded is LVRJ, ? Set to .

When a search/read operation command is input using the key bead 13, the LVR 13 operates, and management information and various index information are read from the index information track of the magnetic tape 14, and the information strikes through the mask circuit 8 and size conversion circuit 7. and stored in the title memory 4 all at once. At this time, when a sort command is input using the key bead 15, various index information in the title memory 4 strikes through the size conversion circuit 7 and the mask circuit 8 and is displayed on the CRT display device 16. In this case, a sequence number is attached to each type of index information displayed. Therefore, the operator searches for the index information corresponding to the required image information from among the displayed index information for each food item, and
The sequence number attached to the index information is input using the - key 15. Then, the index information corresponding to this input jitance number is selected,
Required image information is read from the magnetic tape 14 of LVRI J based on the index information. The read image information is then stored in the Zopuffer 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 read out from the page buffer 5 and supplied to the compression/expansion circuit 6, where it is inversely converted into a mode, and is then read out again. stored in the dibuffer 5. At this time, if a recording operation command is input on the keyboard 15,
The image information in the page buffer 5 is supplied to a hard copy device 17 via a size conversion circuit 7 and a mask circuit 8, where it is recorded on recording paper. Furthermore, if a display operation command is input using the key bead 15, the image information in the page buffer 5 is transferred to the size conversion circuit 7. The signal is supplied via a mask circuit 8° and a display interface device 10 to a CRT display device 16, where it is displayed.

Next, the above-mentioned compression/expansion circuit 6. Size conversion circuit 7.
The mask circuit 89 display interface device 10 will be described 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, assume that the storage capacity of the page buffer 5 corresponds to image information of an A4 size document.

Therefore, during the image information storage operation, if the original 12 is of B5 size, there will be a portion in the storage area of the page buffer 5 that does not store image information. If the image information of the entire area is compressed, even unnecessary image information will be stored in the LVR 13.

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 B5 size stored in the page buffer 5. I'm trying to process it. FIG. 5 specifically shows the compression/expansion circuit 6 and the page buffer 50 peripheral circuit. That is,
Reference numeral 31 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 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. 3
3 is an address counter for specifying a valid area for image information in the line buffer 31. 3
5, ,? Reference numeral 6 denotes a document size information holding unit, which holds, for example, A4 size information and B5 size information.

37 is a selection circuit which receives the command signal CH from the CPU 2;
The holding section 15 according to the size of the document 12 based on D.
,．． 16 outputs are selected. A comparison circuit 34 compares the output of the address counter 33 and the output of the selection circuit 37. Reference numeral 35 denotes an end-of-line detection circuit, which controls the timing generation circuit 32 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 the CPU 2.

(a) 2° dimensional scanning device II during image information storage operation
The image information read by 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 is -A
If the image information corresponds to 4 sizes of originals,
It is impossible to store B4 size image information in the page buffer 5. Therefore, when the document size information inputted from the key gate 15 or the two-dimensional scanning device 11 is larger than the capacity of the 4-di-buffer 5, for example, when the size of the document 12 is B4, the CPU 2 converts the size conversion circuit 7 is reduced 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. Further, 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, the CPU 2 causes the size conversion circuit 7 to perform a strike-through operation (reduction rate "O"). , enlargement rate "0").

(b) During image information storage operation and image information readout,
The image information supplied from the target buffer 5 to the LVR 13 and the image information supplied from the LVR 13 to the page buffer 5 are struck through.

(C) When the read image information is recorded by the hard copy device 17, the image information supplied from the K-Zopuffer 5 to the hard copy device 17 is enlarged, reduced or struck 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 document size information included in index information selected when reading image information. The enlargement operation in this case is for restoring the image information reduced in the above item (a) to its original state. Also, C
The PU 2 causes the enlargement/reduction circuit 7 to perform a reduction operation or a strike-through operation at a predetermined reduction rate depending on the size of recording paper in the hard copy device 17. By doing so, regardless of the size of the recording paper in the hard copy device 17, it is possible to reliably record one unit of read image information.

(d) When displaying the read image information on the CRT display device 16, the image information supplied from the target buffer 5 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 16 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 operating the oilator.
Display contents can be made easier to see.

(・) Did you take out anything else from the pattern generator 9?
? When the turn information is supplied to the R-jivanofa 5 and added to the image information in the Eno puffer 5, strike-through is performed.

FIG. 4 shows the size conversion circuit 2.

41, 4 Z, 4,? , 44 , 45 ,
Each of 46 is a 2048-bit shift register, which sequentially shifts and holds the image information signal V obtained for each scanning line of the two-dimensional scanning device 11 or the image information signal V read out for each line from the page buffer 5. It is something. And this shift register 41, 4
The contents of 2, 43, 44, 45, and 46 are supplied to the product-sum calculation circuit 47 in 6 bits each. As shown in FIG. 5, local information of 6 bits (in the X direction) and 6 lines (in the Y direction) is supplied to the product-sum calculation circuit 47. On the other hand, 4゛8゜49 is an X-direction distance calculation circuit and a Y-direction distance calculation circuit, and according to the enlargement/reduction ratio setting information supplied from the CPU 2, point position information for the local information of the product-sum calculation circuit 47 is provided. This is to set. Therefore, when performing the reduction operation, the product-sum operation circuit 47 performs the fifth
As shown in the figure, weight calculation is performed based on point B for local information. In other words, in Fig. 4, the position of point B corresponds to the reduction rate A, and the point B is set to the value "1", and the value "'1" and the surroundings of point B are set. distance to each black bit (
By setting the distance to the black bit in the vertical and horizontal directions from point B to '1', the distance to the black pit in the diagonal direction from point B becomes 'JT'). The products are calculated (weight calculation) and the sum of these products is output (tf), and the value output from the product-sum calculation circuit 47 is the local concentration with emphasis on point B. , this local concentration is determined by the comparator circuit 50
The comparison circuit 50 outputs a signal corresponding to one pixel bit obtained by reducing the local information. In this way, calculations are performed on all local information set for one unit of image information. In addition,
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 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.

(Breath) During the image information storage operation, the image information read by the two-dimensional scanning device 11 and supplied to the page buffer 5 is masked according to the input document size information. That is, 2
Since the dimensional scanning device 11 has a constant scanning area regardless of the size of the document 12, it is necessary to use only the area corresponding to the size of the document 12 as effective image information. Unnecessary images such as dust and scratches on the document table can be ignored. In addition, the new image information and the apparent image information (masked parts) around it will be stored in the Enova 7a 5 all at once, so even if the old image information is stored in the 4-Zipuffer 5. Even if the old image information is stored, the old image information will not be added to the new image information. Moreover, by doing so, control for clearing the page buffer 5 in advance becomes unnecessary.

(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 does not adhere to the photosensitive drum (not shown), and stains on the photosensitive drum can be reduced.

FIG. 6 shows the mask circuit 8. That is, 5
1.52 is a down counter that is a first counter, such as an X-direction mask counter and an X-direction non-mask counter. It counts clock signals corresponding to pixels of image information read out from the page buffer 5 line by line (corresponding to line scanning by the two-dimensional scanning device 11). Here, in FIG. 7, F
is the scanning area of the two-dimensional scanning device 11, and the original 12 is sectioned into this scanning area F. In this case, the first mask area in the primary direction and the housing X direction has a distance of X1, and the non-mask area (effective area) has a distance of X, -X.

Also, the distance Y is the first mask area in the Y direction of the secondary direction.

So, the distance of the non-mask area (effective area) is Y.

A second counter 56, for example, a down counter that is a Y-direction mask counter and a Y-direction non-mask counter, receives a corresponding line clock signal E or page buffer 5 for each line scan in the secondary direction of the two-dimensional scanning bag M11. The line clock signal E corresponding to each line of image information read out line by line is counted. Therefore, the counter 55 is reset to the value Y, and the counter 56 is reset to the value Y, -Y.
, the values are preset. 57.5

Alternatively, the image information signal V supplied from the page buffer 5 is masked or unmasked.

In this way, in the X direction, the counter 51 first counts down, and when the count reaches 10'', the counter 52 counts down.
countdown begins. And counter 52
When the content of becomes '0'', the counters 51, 51! are grissected again to adapt to the next line.On the other hand, in the Y direction, the counter 55 first counts down,
When the content becomes ``O'', the counter 56 starts counting down. When the content of the counter 56 becomes ``O'', the counters 55 and 56 are preset again to adapt to the next line.

J 75 , 76 , a phase determining circuit 77 and a cursor display H (Hso).

It is rotated to a predetermined angle as necessary and stored in the first glue/flat tour memory 75. The image information read from the first frame tour memory 76 is then supplied to the CRT display unit 16 through the phase determining circuit 77, where it is displayed. At this time, the cursor display device 8
0, when a cursor of a predetermined size is set on the image information in the 16 image information memory pages 5 on the CRT display device, the image information in the area corresponding to the cursor is transferred from the page buffer 5. The data is read out, arbitrarily reduced in size by the size conversion circuit 7, and stored in the second refresh memory 76. When a partial display command is input using the keyboard 15, partial image information within the second glue memory leaf 6 is displayed on the CRT display device 16. By the way, the phase determining circuit 77 is composed of an exclusive OR circuit 78 and an AND circuit 79, and the exclusive OR circuit 77 receives images from the first rate tour memory 75 or the second refresh memory 76. Along with the information signal being supplied, a phase determining signal H based on the input of the key gate 15 is supplied. This phase determination signal H has a logic of 11"
or '0' signal, and by selecting one of them, the phase of the image information can be freely inverted between the self-portrait and the black image.Furthermore, the AND circuit 79 includes Image information signal from exclusive OR circuit 77 and blanking signal I from CPU 2, etc.
