Problems solved by technology

However, if a confidential document is copied and stored, since no magnetic material is attached to the copy, illegal carrying out cannot be detected
[0005] In this way, since the existence of confidential documents can be detected remotely by attaching magnetic materials to confidential documents, it can be considered that this is an effective means to prevent information leakage. No provision is made to attach magnetic material immediately and responsively

Embodiment 1

[0058] figure 1 It is a structural diagram showing a confidential management information recording device that forms confidential management information as additional information on printed paper as a magnetic mark as an embodiment of the additional information recording paper according to the present invention. The confidential management information recording device of this embodiment , is installed on the paper delivery side of the printer 2 as the image forming apparatus, and the paper on which the image information has been printed from the printer 2 enters, and the paper is sent out after forming confidential management information on the paper as required. exist figure 1 In the figure, the conveyance mechanism 10 which conveys paper, and the control circuit 20 which performs drive control of the conveyance mechanism 10, confidential management information formation control, etc. are shown. figure 2 It is a diagram schematically showing the structure of the transport m...

Embodiment 2

[0095] Figure 13 is a block diagram representing the printer, Figure 14 It is a figure which schematically shows the structure of the apparatus conveyance structure part of a printer. Figure 13 is a top view, Figure 14 Side view equivalent to 13. In the above-mentioned first embodiment, the confidential management information recording device is formed as a single device and added to the printer, but in this embodiment, it is characterized in that the confidential management information recording device is incorporated into the printer as a necessary structure, Integrates with the printer.

[0096] exist Figure 13 The illustrated printer 50 includes a conveyance mechanism 60 for conveying the paper 4, a print control circuit 70 for controlling the drive of the conveyance mechanism 60 and image forming processing, and other printer-specific drive controls, and a magnetic circuit 70 for controlling the formation of confidential management information. Mark forming cont...

Embodiment 3

[0102] In the above-mentioned embodiment 2, it is a printer-integrated type, but in this embodiment, Figure 15 An example of application of a printer to a multi-purpose electrophotographic device is shown.

[0103] In the electrophotographic device 90, generally in order to form an image, a charging mechanism 92, an exposure device 94, a developing mechanism 96, a copying mechanism 98, a cleaning mechanism 100, and a fixing mechanism 102 are arranged, and an image is formed on a photosensitive drum 104 by using the exposure device 94 according to image information. Static latent image. Then, an image is formed on the photosensitive drum 104 with the toner by the developing mechanism 96 . The image is copied onto the paper 4 by the copying mechanism 98 to form an image. Here, a magnetic toner is used as the toner, whereby a magnetic pattern corresponding to confidential management information can be easily formed on an arbitrary position on the sheet 4 .

Abstract

A secrecy management information recording device has an information input section which inputs image information printed by a printer and secrecy management information corresponding to the image information, a transport mechanism which receives a printing sheet on which the image information has been printed by the printer, and discharges the sheet after passage over a heat generating resistor, and a magnetic tag forming section which controls generation of heat by the heat generating resistor according to content of the secrecy management information corresponding to the image information printed on the transported printing sheet to thermally transfer at least one magnetic member contained in a thermal transfer sheet onto the printing sheet. A magnetic tag representing the content of the secrecy management information is thereby formed on the printing sheet. This device records additional information corresponding to image information on a printing medium at the time of copying of the image information to the printing medium in such a manner that the additional information is remotely readable.

Description

technical field [0001] The present invention relates to a recording device for adding other information different from the image information to be printed on a printing medium, and particularly to a plate making device having a printing mechanism for recording information on a printing medium such as paper using toner, ink, etc. An apparatus and method for recording, together with additional information corresponding to image information printed on a printing medium output by an image forming apparatus such as a printer, a copier, etc., so that they can be remotely read. Background technique [0002] Conventionally, as a technique for preventing leakage of confidential documents, for example, latent image paper on which a latent image has been formed in advance as a printing medium has been used (for example, refer to Japanese Patent Laying-Open No. 9-295484, Japanese Patent Laid-Open No. 6-212123, JP-A-6-230978, JP-A-7-76196) methods, or by using the latent image formed tog...
