DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical disc device with an image scanner that is integrally provided with an image scanner or an optical disc device.

[Prior Art] In recent years, with the development of information technology, offices are overflowing with a large amount of documents, and the negative effects of this are appearing.

For this reason, many offices require efficient storage that saves space. Furthermore, there are growing calls for a paperless office environment, where paper is completely removed from the office.

On the other hand, the amount of information is steadily increasing with the development of information technology, and it is necessary to access large amounts of information in the course of work.

In this way, while work requires a large amount of documents, there is a contradictory demand to keep the number of documents as low as possible from the standpoint of the office environment.

Optical disk files are used to store documents electronically. Optical disk files can store large amounts of documents, so they can help save space in your office. To record documents on an optical disk device,
An image of a document is input using an image scanner.

[Problems to be Solved by the Invention] However, conventionally, image scanners have been provided as peripheral devices of general-purpose computers together with optical disc devices, and it has not been possible to easily input images to the optical disc device. Furthermore, in order to store documents on an optical disk, complicated registration/search keys had to be attached, and a dedicated operator was required.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide an optical disc device with an image scanner that can easily store documents on an optical disc.

1. Means for Solving the Problem] The above object is to provide a light receiving section that converts an optical image of a document into digital image information, and an image storage section that stores the digital image information converted by the light receiving section, which are replaceable. This is achieved by an optical disc device with an image scanner, which is characterized by comprising an optical disc device that records the digital image information on an optical disc housed in an optical disc cartridge.

[Function] Since the present invention is configured as described above, the optical image of a document can be converted into digital image information by the light receiving section, and this digital image information can be recorded on an optical disc.

[Embodiment] FIG. 1 and FIG. 2 show an optical disc device with an image scanner according to a first embodiment of the present invention. FIG. 1 is an external view of an optical disc device with an image scanner, and FIG. 2 is a functional block diagram thereof.

As shown in FIG. 1, the optical disk device with an image scanner according to the present embodiment has a document table 12 on the top surface of the main body 10 on which a document is placed, as in a normal image scanner.
A paper presser 14 is provided for holding down the original placed on the original table 12.

A cartridge insertion opening 20 is provided on the right side of the main body 10, and an optical disc cartridge 22 is inserted through this cartridge insertion opening 20. When the pushbutton 21 is pressed, the inserted cartridge 22 is removed.

The optical disc device with an image scanner according to this embodiment will be explained in more detail with reference to FIG.

The light receiving unit 30 converts the image of the document 26 on the document table 12 into digital image information. The linear sensor 31 is connected to the document 26
It is moved by a drive unit 32 so as to scan the entire surface of the document 26. The scanning direction of the linear sensor 31 is indicated by an arrow in FIG. Preamplifier 33 amplifies the image signal from linear sensor 31. The amplified analog image signal is converted into a digital image signal by the A/D converter 34. The digital image information of the document converted by the light receiving section 30 is stored in the image memory 35.

The optical disc device 50 records digital image information on the optical disc device 50. The optical disc 51 is the cartridge 2
It is stored in 2. When the cartridge 22 is inserted from the cartridge insertion slot 20, the optical disc 51 is moved by the motor 5.
At the same time, the magnetic field generating coil 54 is lowered to a predetermined position on the cartridge 22.

The motor drive unit 55 drives and controls the motor 53 to rotate the optical disc 51 at a predetermined speed. The coil drive unit 56 drives the magnetic field generating coil 54 to generate a predetermined magnetic field.

The compressed image information is subjected to processing such as amplification by the signal processing circuit 58 in order to be recorded on the optical disc 51. The signal-processed image information is recorded on the optical disc 51 by five optical heads.

The optical head 59 is driven by a head driving section 60 to select a track, and is controlled to eliminate focus errors, tracking errors, etc., and image information is recorded on the optical disk 51.

The control unit 61 includes a motor drive unit 55, a coil drive unit 56,
Controls the head drive unit 60 to drive the optical disc 51 to a predetermined I.
Enable image information to be recorded on the rack. In this embodiment, image information is written to the optical disc 51 in page units, and the image to be converted of the document 26 is recorded one page in sequence. In other words, images are simply recorded in order, without the need for complex code input unlike conventional image files.

A page number counter 62 is provided in the control unit 61 in order to indicate which page of the optical disc 51 the currently recorded image information is on. Each time image information is recorded on the optical disc 51, this page number counter 62 is counted up. The contents of this page number counter 62 are written in a predetermined position on the control track and are displayed on a page number display section 63 provided on the operation panel 24. Note that when the cartridge 51 is installed, the optical disc 5
The number of recording pages written in one predetermined control track is read and stored in the page number counter 62.

However, if there is no more empty area on the optical disc 51, this fact is displayed on the page number display section 63.

The optical disc device 50 of this embodiment can record image information on the optical disc 51 and also erase already recorded image information for initialization. Operation panel 24
These recording and erasing are selected by a recording/erasing selection switch 64 provided at the.

Next, the operation of this embodiment will be explained.

This is the operation when the recording mode is selected by the recording/erasing selection switch 64 in one disk mode.

Before setting the document 26 on the document table 12, the cartridge 22 is first inserted from the cartridge insertion slot 20. Then, the optical disc 51 is attached to the motor 53, and the rotation of the optical disc 51 increases to a predetermined number of revolutions. When the predetermined rotational speed is reached, the contents of the control track are read by the optical head 59, and the number of the last page currently recorded is set in the page number counter 62.

When a document 26 to be input is placed on the document table 12 and a start 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 the image memory 35. This image information is data compressed by a data compression section 57, further subjected to signal processing by a signal processing circuit 58, and outputted to five optical heads.

The control unit 61 instructs the head drive unit 60 to specify the number of pages following the final page number stored in the page number counter 62.

In response to this instruction, the head driving section 60 moves the optical disc 59 to a position on the track to be recorded, thereby recording image information. When recording is completed, the control section 61 increments the page number counter 62 by one and updates the number of pages at a predetermined position on the control track in preparation for the next recording.

When the erase mode is selected by the recording/erase selection switch 64 in the -s mode, the control section 61 controls the coil drive section 56 and the head drive section 60 to initialize the optical disc 51. Initialization is performed by sequentially erasing all tracks on the optical disc 51 one track at a time. During initialization, a message to that effect may be displayed on the page number display section 63.

Note that information (for example, "0") indicating that no image information is recorded is recorded on the control track of the optical disc 51.

In this way, according to this embodiment, it is possible to easily record a document on an optical disk in the same way as copying a document, so information that needs to be filed but will not be viewed immediately can be recorded on an optical disk to avoid a flood of papers. It is possible to accumulate information without inviting information.

Furthermore, since information can be freely recorded and erased on the optical disk of this embodiment, the optical disk can be initialized and used again when it is no longer needed, which is economical.

FIG. 3 shows an optical disc device with an image device according to a second embodiment of the present invention. Components that are the same as those in the first embodiment shown in FIGS. 1 and 2 are designated by the same reference numerals, and their explanations will be omitted.

This embodiment differs from the first embodiment in that image information stored in the image memory 35 can be displayed and image information recorded on the optical disc 51 can be read.

The optical disc device 50 of this embodiment can also perform recording and erasing on the optical disc 51 as well as playback. Recording, erasing, and reproducing are selected by a recording/erasing/reproducing selection switch 65 provided on the operation panel 24. The operation panel 24 is further provided with a reproduction page designation section 66 for specifying the number of pages to be reproduced. The playback page designation section 66 includes, for example, a numeric keypad for directly inputting the number of pages and a search key for searching the number of pages to be played back.

The image information read from the optical disc 51 by the five optical heads is subjected to predetermined signal processing by the signal processing circuit 58, and then data is developed by the data development section 67 and stored in the image memory 35.

This embodiment further includes a flat display 70. This flat display 70 is provided to display image information stored in the image memory 35. This flat display 70 is connected to the image memory 35 via a display control section 71 that controls the display of image information.

This flat display 70 may be provided anywhere in the optical disc device with an image scanner.

For example, it may be provided on the paper presser 14, or it may be provided on the main body 10.
It may be provided on the side surface of the screen or may be provided on the operation panel 24.

Note that the flat display 70 may be any display means such as a liquid crystal display panel, an EL display panel, or a plasma display panel.

In this manner, the contents of the image memory 35 can be displayed on the flat display 70 in this embodiment. Therefore, the reproduced image of the optical disc 51 can be viewed on this flat display 70. Furthermore, if the image input by the light receiving section 30 is checked in advance on the flat display 70 when recording on the optical disc 51, recording of an input defective image can be avoided.

The present invention is not limited to the above-mentioned embodiments, and various modifications are possible.

For example, in the embodiments described above, a magneto-optical disk that can be erased may be used as the optical disk, or a phase change type optical disk that can also be erased may be used. Alternatively, a write-once optical disc may be used, which cannot be erased, but once written, becomes a permanent record.

When a write-once optical disc is used, information recorded on paper can be stored compactly, similar to conventional microfilm.

[Effects of the Invention] As described above, according to the present invention, documents can be easily stored on an optical disk.
