Each person operates the copying machine 10 with an optical disk device.

Although the detailed configuration of the optical disc device-equipped copying machine 10 will be described later, the optical disc device-equipped copying machine 10 can be operated to record a document on an optical disc in the same way as copying a document. Incidentally, a copying machine with an optical disk device is described in detail in Patent Application No. 170036 of 1988 and Patent Application No. 174076 of 1988 filed by the applicant of the present application.

The read-only optical disc device 30 is placed on the desk of each member of the office, and each person operates it as necessary.
You can view the contents of a document in the same way as viewing a regular file. Note that if the read-only optical disc device 30 is kept at home, it is possible to work from home by simply bringing the small optical disc 12 home. The details of this playback-only optical disk device "J130" will be described later.
No. 69525 describes a read-only optical disc device in detail.

The flow of recording, storing, reproducing, and erasing documents using the simple electronic file system of this embodiment will be explained with reference to FIG.

Document 2 that requires recording is a copy with optical disk device II
o is recorded on the optical disc 5. At this time, the optical disc cartridge 4 containing the optical disc 5 on which a hard copy 6 is recorded, which can also be taken as a hard copy 6 if necessary, is stored on a desk or shelf in the usual way, but compared to the case of recording on paper, the optical disc cartridge 4 is Because it is compact, there is no need to worry about storage space, and the capacity of one A4 sheet is 1000 to 200.
If an optical disk 5 with approximately 0 pages is used, the capacity will be almost equal to that of a normal paper file, and one optical disk cartridge 4 can be loaded as if it were one large file. can.

Next, an overview of the search method in the simple electronic file system of this embodiment will be explained using FIGS. 3 and 4.

In the simple electronic file system of this embodiment, when a document is stored on an optical disk, it is recorded in page units in order.

and the title TL of each page. The page address PA is the track number TN where the image is recorded.
and sector number SN. The disc name DN and title TL are input by the operator at the time of recording, but they are for the operator to remember when playing back and do not necessarily have to be recorded.In particular, even if the title TL is recorded, multiple pages recorded in the title column of the first page of the document. The page address PA is automatically recorded by the copying machine 10 with an optical disk device at the time of recording.

When playing an optical disc on which the management data shown in Figure 3 is recorded, the management data area is scanned first, and the "disc name", "title", and "number of pages" are displayed as shown in Figure 4. . That is, the "disc name" is displayed at the top of the reproduced image, and the "title" and "page number" are sequentially displayed at the bottom, like a table of contents of a normal book.

The operator looks at this display, specifies the number of pages of the document required, and reproduces it.

With conventional electronic file systems, the amount of documents that can be stored on a single optical disk is extremely large, making registration difficult. /search key was used, but in this example, since the capacity of one sheet is about 1000 to 2000 pages on A4 paper as mentioned above, it is basically managed by the number of pages as described above, and the page number management is assisted. It is distinctive in that the title is used as

A first specific example of a copying machine with an optical disk device in the simple electronic file system of this embodiment is shown in FIGS. 5 to 7. In this specific example, the copying machine with optical disk device is

On the upper surface of the main body 110 in front of the document table 112, there is provided a power switch 122 as well as an operation panel 124 for normal copying operations and optical disk device operations.

The copying machine with an optical disk device according to this specific example will be explained in more detail with reference to FIG.

The light receiving unit 130 converts the image of the object 2 on the document table 112 into digital image information. The linear sensor 131 reads the image ('A) of the object 2, and the drive unit 132
The entire surface of the object 2 to be copied is moved by the operator.

Preamplifier 133 amplifies the image signal from linear sensor 131. The amplified analog image signal is converted into a digital image signal by the A/D converter 134.

The digital image information of the object converted by the light receiving section 130 is stored in the image memory 135. The selection unit 136 sets the digital image information stored in the image memory 135 to 0.
You can choose whether to print on paper, record on an optical disc, or record on an optical disc as well as print on paper. This selection is made by a paper/'disc selection switch 137 provided on the operation panel 124.

Laser printer section 140 prints digital image information on paper. The laser scanning section 141 irradiates the rotating photosensitive drum 142 with a laser beam while scanning it while changing its intensity to form a bright and dark image according to the digital image information output from the selection section 136. . The bright and dark image formed on the photosensitive drum 142 is transferred to a paper 143 in the usual manner.
transcribed into. The printed paper is discharged to a copy receiver 118.

The optical disc device 150 records digital image information on the optical disc 5. The optical disc 5 is housed in the cartridge 4. When the cartridge 4 is inserted through the cartridge insertion port 120, the optical disk 5 is mounted on the motor 153, and at the same time, the magnetic field generating coil 154 is lowered to a predetermined position in the cartridge 4.

A motor drive unit 155 drives and controls the motor 153, and a nine-coil drive unit 156 that rotates the optical disc 5 at a predetermined speed drives the magnetic field generating coil 154 to generate a predetermined magnetic field.

The digital image information output from the selection section 136 to the optical disc device 150 is data compressed by a data compression section 157 for recording. For example, modified RE is an international facsimile standard.

The compressed image information is subjected to processing such as amplification by the signal processing circuit 158 in order to be recorded on the optical disc 5. The signal-processed image information is recorded on the optical disc 5 by the optical head 159.

The optical head 159 is driven by a head drive unit 160 to select a track, and is controlled to eliminate focus errors, tracking errors, etc., and image information is recorded on the optical disc 5.

The control unit 161 includes a motor drive unit 15 and a coil drive unit 1.
56, controls the head drive unit 160 so that image information is recorded on a predetermined track of the optical disc 5; In this specific example, image information is written to the optical disk 5 in units of pages, and the image to be copied on the object 2 is written in one page.
Pages are recorded one after the other, that is, they are simply recorded in order without inputting complicated codes like in conventional image files.

However, at this time, the aforementioned management data can be input from the data person key 168 into the management data area in the optical disc as needed. That is, when using a new optical disc, the disc name DN is input, and each time a document is recorded, the document title TL is input. Data input key-1
The contents input from 68 are displayed on the display section 163, and the operator can input the contents while checking the contents.

An example of the data entry key 168 is shown in FIG.

This is an example of a simple version with a small number of keys.

A data key is provided in the center of the data entry key 168. Data keys include the alphabet keys from A to Z and the space key, and some of the alphabet keys are numeric keys from 0 to 9, r, r, etc.

It can be switched to symbol keys such as ",", "/", "*", and "#". The left part of the data input key 168 contains alphabetic characters /
Control keys are provided, including a kana/numeric switching key, a C (- character cancel) key, and an AC (all character cancel) key.
The right portion of 68 is provided with a left scroll key, a right scroll key, a non-conversion key conversion/next candidate key, and a SET key.

The alphabetic/kana/numeric switching key selects whether the manual key input mode is alphabetic character input mode, kana input mode using Roman characters, or numeric input mode. Since there is a key to switch between alphabetic characters, /kana, and numbers, the number of keys can be reduced.

The C (- character cancel) key is a key for correcting 16 input characters. Delete the last character entered.

AC (cancel all characters):! Ir- deletes all characters entered. After deletion, the operator starts inputting from the beginning.

The left scroll key and right scroll key are used to scroll the display of the input disc name and title left and right.The no conversion key and the conversion/next candidate key are used to control kana-kanji conversion when inputting kana characters in romaji. This is the key.

The SET key is a key for registering an input character string.

By operating this data person key 168, the operator can input not only alphanumeric symbols, but also hiragana and katakana by inputting Roman characters, and kanji by converting kana-kanji.

A page number counter 162 is provided in the control unit 161 in order to indicate which page of the optical disc 5 the currently recorded image information is on.

Each time image information is recorded on the optical disc 5, this page number counter 162 is counted up. The contents of this page number counter 162 are displayed on a display section 163 provided on the operation panel 124.

The management data generation unit 169 receives the input contents from the data input key 168 and the page address PA from the control unit 161.
and the number of pages from the page number counter 162, management data according to the format shown in FIG. 3 is generated. This management data is processed by the signal processing circuit 158 and recorded in the management data area of the optical disc 5.

When the cartridge 4 is installed, the management data written in the predetermined management data area of the optical disc 5 is read,
The final page number obtained from the management data is stored in the page number counter 162. However, if there is no longer an empty area on the optical disc 5, this fact is displayed on the display section 163.

The optical disc device 150 of this specific example can record images + PL information on the optical disc 5, and can also initialize by erasing already recorded images and information. Record/erase selection switch provided on the operation spring 124
4, these recording and erasing are selected.

Next, the operation of this specific example will be explained.

When the 9-mode paper/disk selection switch 137 selects the copying mode for copying onto paper, the selection section 136 outputs digital image information only to the laser printer section 140 and outputs it to the optical disk device 150. If you place the object 2 on the document table 112 and press the copy switch (not shown), the laser printer unit 140
The image (3 information) is copied onto paper.

- If the paper/disc selection switch 137 at stage 9-' selects the disc recording mode for recording on an optical disc, and the recording/erase selection switch 164 selects the recording mode, the selection unit 136 selects the digital image information. It is output only to the optical disc device 150 and not to the laser printer section 140.

Before setting the object 2 to be copied on the document table 112, the cartridge 4 is first inserted through the force insertion opening 120.

Then, the optical disc 5 is mounted on the motor 153, and the rotation of the optical disc 5 increases to a predetermined number of revolutions. When the predetermined number of rotations is reached, the contents of the control track are read out by the optical hand 159 and the number of the last page currently recorded is set in the page number counter 162.

When the copy object 2 to be copied is placed on the document table 112, a display prompting the operator to input the title TL of the document is displayed on the display section 163. The operator inputs the data key as necessary.
168 to input the title TL. After inputting the title, when a copy switch (not shown) is pressed, the image information is read by the light receiving section and converted into digital image information. The converted image information is stored in image memory 135.

The selection unit 136 outputs image information only to the optical disc device 150 as described above. This image information is stored in the data compression unit 1
The data is compressed by the signal processing circuit 157 and further processed by the signal processing circuit 158.
The signal is processed and output to the optical head 159.

The control unit 161 instructs the head driving unit 160 to select the next track and sector where the final page number stored in the page number counter 162 is recorded. In response to this instruction, the head drive section 160 moves the optical head 159 to position it on the track to be recorded and records image information, as well as records the title TL and page address PA at a predetermined position in the management data area. When the recording is completed, the control unit 161 increments the page number counter 162 by 1 in preparation for the next recording.

- When the paper/disc selection switch 137 selects the paper copy/disc recording mode in which copies are made on paper and also recorded on an optical disc, the selection section 136 transfers the digital image information to the laser printer section 140 and the optical disc device. 150.

In this mode, the above-described paper copying mode and disc recording mode operations are performed simultaneously.

- When a disc recording mode for recording on an optical disc is selected by the low/disc selection switch 137 and an erase mode is selected by the recording/erase selection switch 164, the control unit 161 controls the coil drive unit 156 and the head. The drive unit 160 is controlled to initialize the optical disc 5. Initialization is performed by sequentially erasing all tracks on the optical disc 5 one track at a time. During initialization, the display section 16
3 may be displayed to that effect. Note that information indicating that no image information is recorded at all (for example, "0") is recorded on the control track of the optical disc 5.

According to such a copying machine with an optical disk device, the content of a document can be easily recorded on an optical disk in the same way as copying, so it is suitable as an optical disk recording device in a simple electronic file system. In addition, documents can be copied and recorded on optical disks, so information that needs to be filed but not immediately viewed can be recorded on optical disks, making it possible to accumulate information without causing a flood of vapor. be. However, since the optical disk device of this specific example can freely record and erase information in a copying machine, it is economical to initialize the optical disk and use it again when it is no longer needed.

FIG. 8 shows a second specific example of the second copying machine with an optical disk device. Components that are the same as those in the first specific example shown in FIGS. 5 to 7 are denoted by the same reference numerals, and their explanations will be omitted.

This specific example is also a digital copying machine equipped with an optical disk device, but differs from the first specific example in that the image information recorded on the optical disk is read, printed on a sheet of paper, and displayed.

The optical disc device 150 of this specific example is capable of recording and erasing data on the optical disc 5 as well as reproducing data. Operation panel 124
These recording, erasing, and reproducing are selected by a recording/erasing/reproducing selection switch 165 provided in the . During playback, the management data of the optical disc 5 is read out and displayed on the display section 163.

The number of pages to be reproduced is specified using the numeric keys of the data entry key 168 on the operation panel L; 124 or the search key.

The image information read from the optical disk 5 by the optical head 159 is subjected to predetermined signal processing by the signal processing circuit 158, and then data is developed by the data development section 167.
The image is stored in the image memory 135. And image memory 1

This specific example is further provided with a flat display 170. This flat display 170 is provided to display image information stored in the image memory 135. This flat display 170 is connected to the image memory 135 via an image display section 171, and the image information stored in the image memory 135 is always displayed. Note that the flat display 170 may be provided with an on/off switch to select whether or not to display the information.

This flat display 170 may be provided anywhere in the copying machine with an optical disk device.
4, the side surface of the main body 110, or the operation panel 124.

Note that the flat display 170 may be any display means such as a liquid crystal display panel, an EL display panel, or a plasma display panel.

Note that when the management data is printed on paper by the laser printer unit 140 or displayed on the flat display 170, the management data is recorded in character codes, so the read management data is transferred to the data expansion unit. 167, the character pattern from the character pattern generating section 166 is used to convert it into image information, and the image information is stored in the image memory 135.

According to such a copying machine with an optical disk device, the contents of the image memory 135 can be displayed on the flat display 170. Therefore, when recording on the optical disk 5, the image inputted by the light receiving section 130 can be displayed on the flat display 17.
By checking in advance using 0, it is possible to avoid recording an input defective image. Further, when reproducing the optical disc 5, if the reproduced image is checked in advance before printing on paper, it is possible to prevent unnecessary hard copies.

- A third specific example of the copying machine with an optical disk device in step 3 is shown in FIG. 9. The same components as in the first and second specific examples are given the same reference numerals, and their explanations are omitted. .

In this specific example, an optical disk device is installed in a so-called analog copying machine that directly irradiates a photosensitive drum with an image from an object to be copied using an optical system.

The copying machine with an optical disk device of this specific example is basically an analog copying machine, and a copying object 2 placed on a document table 112 is copied by a copying section 180.

While illuminating the object 2 with the light source 181, the reflected image is transmitted to the mirrors 182, 183, 184, 186 and the lens 18.
An image is formed on the surface of the photosensitive drum 187 by an optical system composed of 5. That is, the image of the object 2 reflected by the mirror 182 that is moved together with the light source 181 is reflected from the mirror 1.
The optical path is bent by 83 and 184 and guided to the lens 185. The image light converged by the lens 185 is sent to the mirror 1
