2. Description of the Related Art Documents created by a word processor (document creator) or personal computer (personal small computer) are usually stored in a magnetic storage medium, but this document information is the easiest to send to others. Another method is to print the document information on a recording paper and mail it or send it by a facsimile machine. However, when the person who receives the document tries to convert the document information into electronic information again, the person who receives the document reads it and re-inputs it with an input device, or uses a reading device with a type recognition function. The document must be read and converted into electronic information. Not only are readers with type-recognition expensive and uncommon, but they can be unreadable because the image is degraded when the document is sent by a fax machine or copied by a copier. . As means for solving such a problem, for example, in the case of converting the document information into a bar code in JP-A-5-12288, recording the bar code on a recording paper and storing the bar code, and converting the bar code into electronic information, An invention of an information processing device in which document information recorded on a recording paper by a barcode is read by a relatively inexpensive barcode reading device is disclosed.

[0003]

However, in the above information processing apparatus, since the document information is only converted into the bar code and recorded on the recording paper, the creator of the document, its affiliation, the creation date and time, the document name, The accompanying information of the document such as the model name of the device and the format information such as the type and size of the type must be separately input, which is troublesome. Further, even if the document information is recorded as a bar code on the recording paper for the purpose of maintaining confidentiality, it can be easily read by the bar code reading device, which is insufficient as a management form of the confidential document. The present invention has been made to solve the above problems in the prior art, and it is possible to easily obtain accompanying information unique to the coded information relating to a document, an image, etc. recorded on a recording sheet, and to obtain the coded information. It is an object of the present invention to provide an information recording device which is effective for maintaining confidentiality of information.

[0004]

In order to solve the above problems, the present invention provides an input means for inputting data of coded information relating to a document, an image, etc., and coded information input to the input means. In the information recording apparatus, which comprises bar code converting means for converting data into bar code data, and bar code recording means for recording a bar code image corresponding to the bar code data on recording paper based on the bar code data, the input It is provided with an incidental information recording means for recording incidental information peculiar to information on a recording paper. Further, preferably, incidental information input means for inputting incidental information or incidental information output means for outputting incidental information, and bar code reading means for reading the bar code image recorded on the recording paper and converting it into bar code data. And incidental information read means for reading the incidental information recorded on the recording paper, incidental information read by the incidental information reading means and incidental information input from the incidental information input means, or incidental information output from the incidental information output means. By comparison, it has a propriety determining means for determining whether or not the barcode image corresponding to the barcode data output from the barcode reading means can be recorded by the barcode recording means.

[0005]

When the coded information data is input to the input means, the bar code conversion means converts the coded information data into bar code data. While the barcode recording means records the barcode image corresponding to the barcode data on the recording paper based on the barcode data, the incidental information recording means records incidental information unique to the input information on the recording paper. In a preferred means, the barcode reading means reads the barcode image recorded on the recording paper and converts it into barcode data. The incidental information reading means reads the incidental information recorded on the recording paper. The adequacy determining means compares the incidental information read by the incidental information reading means with the incidental information input means or compares the incidental information output from the incidental information output means with the barcode data output from the barcode reading means. Whether or not the corresponding barcode image can be recorded by the barcode recording means is determined.
