The compressed image data is recorded as bit information by a head (not shown) controlled by an optical disk drive control section 235 onto a destination disk 233 whose rotation is controlled by an optical disk drive motor 234.

When reading an image, the head reads out the information recorded at a specific position on the optical disk 233 based on the control information (search information identified from the abstract) from the basic system section 1, and sends the information to the image processing section via the image bus 7. 2 CODEC2
1 and then temporarily stored in the page memory 30. The image data recorded in the page memory 30 is subjected to predetermined processing by the image processing module 20 and output to the printer 43 via the image bus 7 and the printer interface 42.

Further, the printer 43 includes an image forming section 239 that combines a laser optical system 240 and an electrophotographic method capable of forming images on both sides of transfer paper.

That is, image data sent from the page memory 30 via the image bus 7 and the printer interface 42 is synchronized by an image data processing circuit (not shown), and is synchronized by a semiconductor laser oscillator (not shown). light 24
Outputs 5.

The output laser beam 245 is shaped by a beam shaping optical system (not shown) consisting of, for example, a cylindrical lens, and then driven by a high-speed rotating motor 214- using an air bearing.
It is deflected by a polyhedral rotating mirror 241-1 which is rotationally driven. The deflected laser beam 245 passes through the fθ lens 242, is reflected by the mirror 243 and the mirror 244, and forms a spot with the necessary resolution at the exposure position 246A on the photoreceptor drum 24G via the protective glass 244-1. A latent image is formed on the photosensitive drum 246 by scanning and exposing the image. This deflected laser light 245 is synchronized by detecting the laser light with a beam detector (not shown) consisting of a photodiode.

Around the photoreceptor drum 246, the photoreceptor drum 24

Ru. The laser beam 245 is spot-imaged at the exposure position 246A on the charged photoconductor drum 246, and a latent image is formed on the photoconductor drum 246 until it reaches the development position 246B.
At this position, the latent image on the photosensitive drum 246 is formed as a toner image by the developing device 248. The photoreceptor drum 246 on which the toner image has been formed continues to rotate at VO, and at the transfer position 246C, the transfer roller 249 is placed onto the transfer paper P fed at the right timing by the paper feeding system.
Transcribed by. Unnecessary toner adhering to the transfer roller 249 is cleaned by a transfer roller cleaner 249-1.

), one sheet of the transfer paper P is separated and fed, reaches the registration rollers 255, and is fed to the transfer section at a predetermined timing.

The elevator 252-1 of the large-capacity feeder 252 moves up and down according to the number of sheets so that the height of the sheet at the sheet feeding section is approximately constant.

Further, on the downstream side of the transfer roller 249, there is a paper transport mechanism 256, a fixing device 257, and a path switching guide 26o1 for switching between ejecting the image-formed transfer paper P to the outside of the machine and guiding it to the reversing paper feed section. A roller 258 is provided. The path switching guide 260 changes the path of the transfer paper P sent from the fixing device 257 in the direction of AA%BB as shown. For example, when the route switching guide 260 is in the illustrated state,
The transfer paper P advances to the path AA, passes through the paper ejection roller 258, and then
The paper is ejected to the paper ejection tray 259.

Furthermore, an example in which images are formed on the first side (front side) and the second side (back side) of the transfer paper P will be described in detail.

That is, after the image forming process described above, the transfer roller 249
The transfer paper P on which the toner image corresponding to the image data on the first side (front surface) of the transfer paper P, for example, the cover data of the abstract, has been transferred is sent to the fixing device 257 by the paper transport mechanism 256, and the toner image is It is fixed on the transfer paper P. The path switching guide 280 rotates counterclockwise (the state shown by the dotted line), and the transfer paper P that has left the fixing device is conveyed to the path BB.

Further, the transfer paper P passes between the reversing rollers 261A and 261B and is sent to the reversing grip roller 262. After the rear end of the transfer paper P passes between the reversing rollers 261A and 261B, the grip roller 262 stops rotating and rotates clockwise while holding the transfer paper P (as shown by the dotted line). The transfer paper P is reversed and the transfer paper P is transferred to the reversing rollers 261A, 261.
C, passes through the conveyance roller 263, reaches the registration roller 255, and is transferred to the transfer position 246 at a predetermined timing.
It is fed to C.

At this time, a toner image corresponding to the image data on the second side (back side) of the transfer paper P, for example, the back side data of the above-mentioned abstract, is formed on the second side (back side) of the transfer paper P, and the transfer paper P is The toner image is sent to the fixing device 257 by the transport mechanism 256, and the toner image on the second side (back side) of the transfer paper P is fixed on the transfer paper P. The path switching guide 260 rotates clockwise (the illustrated state), and the transfer paper P advances to the path AA, and is ejected onto the ejection tray 259 by the ejection roller 258.

FIGS. 3(a) and 3(b) show that when the registration operation is performed in the file mode in this device, the printer 43 prints the transfer paper.

The above volume number is among the many optical discs 233.
This number indicates which optical disk 233 this document is stored in, and is automatically numbered by the basic system unit l when the document information is loaded into a new destination disk 233 or optical disk device 51 for which document information has not been registered. It is a consecutive number of digits (3 digits). The above file number is the specified optical disc 2
This is to identify which one of the many document information stored in the disk 33 corresponds to the previous disk 23.
This is a several-digit (4-digit) number assigned to each document according to the order in which it is registered in No. 3. Memory date and ID code number (
5 digits for both) is provided to solve the inconvenience that if there are multiple implementation machines, the above 7 digit numbers will always result in documents with the same number. There is almost no possibility that documents with numbers will be generated even if they pass through multiple machines.

New date information is always issued by a battery-backed time-only IC (not shown) included in CPU10 in FIG.

Next, an example of the operation of the copying apparatus of the present invention will be described.

First, document registration and abstract creation will be explained with reference to the flowchart shown in FIG. A plurality of sheets (N sheets) of originals are set on the scanner 41, and an optical disk 233 is set on the optical disk device 51, respectively.

At time 2, CPU10 detects the attachment of the optical disk 233, accesses the optical disk 233, and
Volume number, number of registered files, as registration status of
The unregistered space capacity and the like are displayed on the display panel 12.

On the other hand, if the optical disc 233 is a new optical disc 233 with no document information registered, initialization processing is performed. In the initialization process, the optical disc 2 is
33, issues a volume number, and registers it in the search information area of the optical disc 233. In addition,
At this time, an ID code number other than the volume number is also registered using the keyboard 11.

When the user confirms that the document can be registered through the message on the display panel 12, the user presses the reading start button (not shown) on the keyboard 1.1 to read the document information on the first page using the scanner 41. The image is converted into a signal, subjected to various image processing such as filtering processing and gradation processing, and then temporarily stored in the page memory 30 (herein referred to as page A) via the image bus 7. Subsequently, the stored image data is compressed by the C0DEC 21 and then loaded onto the optical disc! It is stored on the optical disk 233 through f51. At the same time, under control from the basic system section 1, the document information to be registered is recorded on the optical disk 23.
A four-digit file number is assigned to each document according to the order in which the documents are registered. The file number issued here is stored in the destination disk 233 as search information in the destination disk 233.
registered in the search information area.

On the other hand, the image data stored in the page memory 30 includes
A bar code and image data of a number string are added as search information including the volume number, file number, etc. The document information of the first page to which the barcode and the image data of the number string are added is printed out as the cover of the abstract by the printer 43 via the image bus 7 and the printer interface 42.

Next, scan the document information of the second page using the scanner 41 in the same way as for the first page.
is converted into an electrical signal and temporarily stored in the page memory 30 via the image bus 7. Further, the stored image data is compressed by the C0DEC 21 and then transferred to the optical disc through the destination disc device 51.
It is accumulated in 33. On the other hand, the image data stored in the page memory 30 is subjected to a reduction process of 1/4 (area ratio: 1/1B). Various processing methods can be considered, but here the image data is compressed by simple thinning processing. 1
The image data compressed to /1B is temporarily stored in a specific page memory 30 (here referred to as page 8) allocated for the back side of the abstract.

The above processing is repeated until the 18th page or the final page. moreover,
Similar to the first page, search information using a barcode and a number string is added as key information at the time of search.

As described above, the document information on the back side of the abstract to which the search information has been added is printed out via the image bus 7 and the printer interface 42 by the print 43 on the back side of the transfer paper P as the abstract, which has already been recorded on the front side. Ru.

Further, for documents from pages 18 to 33, a reduced image is printed on the front side of the second page with search information added, similar to the procedure for creating the back side of the first page. For documents of 33 pages or more, search information is added to the reduced images and printed on the front or back side of the transfer paper P every 16 pages.

The images of the image information of this abstract are shown in Figure 3 (a) (b) (
Shown in C). Figure 3 (a) is the surface of the first sheet, Figure 3 (b)
shows an example of the back side of the first sheet, and the same figure (C) shows an example of the front side of the second sheet.

With the above, the original information is transferred to the destination disk 2 as image data.
33, and the front of the first page records the document information of the first page, and the back of the first page and the front of the second page record a reduced document that represents the entire document information. It will be done.

Next, document search and copying will be explained based on the flowchart shown in FIG. First, scan the abstract into the scanner 41.
and set the first disk 233 in the first disk device 51 respectively. At this time, CPU10 detects the attachment of the destination disk 233 using the same control as when registering the document, accesses the optical disk 233, and records the registration status of the destination disk 233 including the volume number, number of registered files, file number, and unregistered space capacity. etc. are displayed on the display panel I2.

This makes it possible to confirm to some extent whether the document information corresponding to the abstract is registered on the optical disc 233. Also, at this time, various search modes such as copy pages can be set using the keyboard 11.

Then, use the display on the display panel ■2 to search for documents.
After confirming that copying is possible, press the copy button (not shown) on the keyboard 11 to send the barcode BCDI (BeO2) recorded in the abstract to the scanner 4.
1 and CPU10 reads that barcode BCD1.
Search information is detected from (BeO2). This detected search information is compared with the search information on the optical disc 233. That is, first, it is checked whether the volume number registered in the search information area of the optical disc 233 matches the volume number obtained from the abstract, and if they match, then the file number that matches the file number obtained from the abstract is checked. It is checked whether or not it is registered in the search information area of the optical disc 233, that is, a search is performed.

As a result, if there is a matching file number, image data is read page by page from the image data area corresponding to the file number. The image data read from the optical disk device 51 is first decompressed by the C0DEC 21 and then temporarily stored in the page memory 30 via the image bus 7.

The image data stored in the page memory 30 is transferred to the printer 4 via the image bus 7 and the printer interface 42.
3, each page is printed out.

Print out all the way to the last page.

On the other hand, if the volume number of the optical disc 233 installed is different from the volume number obtained from the abstract,
The document search is stopped and a message such as "Volume number is incorrect" is displayed on the display panel 12. In addition, if the volume numbers match but other contents such as file numbers do not match, the display panel 12 will display "No matching document".
Displays a message such as "Document search" and cancels the document search.

As described above, the original manuscript information can be easily and immediately obtained from the paper on which the abstract information is recorded.

As mentioned above, image information is converted into digital data and read by a scanner, this read digital data is stored on an optical disk, and abstract information of the digital data stored on this optical disk is recorded, and this abstract information Search information indicated by a barcode for the copy is added to the copy paper.

This simultaneously satisfies the advantages of the immediacy of information access of paper files and the large storage capacity of electronic files.In other words, multiple sheets of manuscript information can be recorded as two sheets of simple abstract information. By replacing the image information stored on the optical disk with the image information of the document, it is easy to register and search the image information of the document, and it is possible to significantly reduce the document space. Since this is done based on the above, it is possible to prevent the speed of accessing information, which is an advantage of paper files, from being impaired.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide an image forming storage device that can easily and easily register and search images at a low cost.
