Hereinafter, the embodiment for carrying out the present invention will be described more specifically. However, the present invention is not limited to these specific embodiments.
(Magnetic ink or toner)
The magnetic ink or toner according to the present invention is a magnetic ink or toner characterized by containing an amorphous magnetic powder, and means an ordinary ink or toner composition further containing an amorphous magnetic powder. Examples of the normal ink or toner include normal ink for inkjet printers and toner for laser printers. Further, it also contains a normal ink for an ink jet copying apparatus or a toner for a laser copying apparatus.

The movement of the magnetic domain in the process is easy, it has excellent soft magnetism and low loss, the direction of magnetic properties can be controlled by heat treatment, and (2) the particle diameter is not particularly limited, It means what has been pulverized so as to have a particle size of several μm or less.
Here, the type of the magnetic alloy (1) is not particularly limited, and various magnetic alloys can be used. In the present invention, it is particularly preferable to use a soft magnetic alloy. Specific examples include ferrosilicon cobalt alloys. Examples of the pulverization treatment that can be used to obtain the particle size of (2) include a usual method, for example, a pulverization treatment method by a high-pressure pulverization method. In the present invention, these amorphous magnetic powders can be used alone or mixed with other kinds of amorphous magnetic powders.

    Further, there are no particular limitations on the magnetic ink and toner composition used in the present invention, and the production method thereof. According to the conventional ink, toner composition, etc., and the production method mentioned above, The amorphous magnetic powder of the present invention described above may be added to the ink or toner composition. There is no particular limitation on the particle size, particle size distribution, or addition amount of the amorphous magnetic powder of the present invention as an added component. The magnetic ink can be appropriately selected according to the purpose, method and apparatus of use, and the type and sensitivity of the magnetic sensor for detection described below.

  Furthermore, the magnetic ink or toner of the present invention is not necessarily required to exhibit a visible color, and may be substantially colorless or exhibit a color similar to that of a paper medium. If desired, a pigment of the preferred color can be added to the composition to produce the desired color. Furthermore, for the purpose of obtaining various color combinations, the color ink and color toner containing the amorphous magnetic powder of the present invention can be obtained by adding the amorphous magnetic powder of the present invention to various color inks and color toners. It is possible to prepare. One of the remarkable effects obtained in the present invention is that it is possible to print on a paper medium with a character size using color ink and color toner containing the amorphous magnetic powder of the present invention. Therefore, the printed matter on the paper medium obtained in this way can constitute information, confidential information itself, or a part thereof, as used in the present invention.

  In addition, in a medium printed with a magnetic ink or toner containing the amorphous magnetic powder of the present invention, the amorphous magnetic powder is fixed on the medium through normal processing. This is the same as the state in which the pigment in normal ink or toner is fixed on the surface of the medium. Also, the amount of amorphous magnetic powder fixed on the medium can be changed by changing the printing method (mainly controlling the amount of ink). Further, the amorphous magnetic powder that is printed and fixed on the medium is fixed in an arbitrary shape at any arbitrary position on the surface of the medium by a printing method.

It is also possible to print using the magnetic ink or toner of the present invention and further print using a different or the same magnetic ink or toner. Thereby, the magnetic substance powder of the present invention can be fixed on the medium, for example, at least partially having a layered structure.
The magnetic powder fixed on the medium exhibits magnetic properties as individual magnetic particles. Therefore, each of the fixed magnetic powder can be magnetized or demagnetized (non-magnetized). It is also possible to magnetize a certain range of the fixed magnetic powder and to demagnetize (demagnetize) the magnetism. As a result, various sizes of magnetized and non-magnetized regions can be generated.
Each of the magnetically fixed magnetic powders can be magnetized, demagnetized (non-magnetized), or magnetized again according to the properties of the amorphous magnetic powder selected in the present invention. Various conventional devices (magnetization head, magnetic write head, etc.) can be used.

The confidential document management system and the confidential document management apparatus of the present invention are characterized by using the magnetic ink or toner of the present invention having these characteristics.
(Confidential document management system)
The confidential document management system of the present invention means a system for managing information recorded on a medium. Here, the “confidential document” does not mean only a document that includes general information widely and is classified as “confidential”. Therefore, the “confidential document” as used herein specifically includes not only a document (information recorded on a medium) that is treated as “confidential” (or “secret”) for some purpose, Documents that are classified as “confidential”, but are not currently classified as “confidential” and include documents that are not originally classified as “confidential”. Specifically, the document that is not treated as “confidential” includes a document for publication, an identification label for goods / products, an identification tab, or securities.

  The “information” as used in the present invention is information recorded on a medium. The information is not particularly limited as long as it can be recorded (expressed) on a medium, and means information expressed by various characters, figures, patterns, colors, or combinations thereof.

  The “medium” as used in the present invention is not particularly limited, and means all recordable materials having various ordinary materials, sizes, and shapes. Accordingly, materials that can record (or represent) the information described above in any way are included. In particular, all materials that can be recorded with the magnetic ink or toner of the present invention are included. Specifically, "paper" made of natural fiber or artificial fiber material, "fabric" or a sheet made of a combination thereof, "artificial paper" made of polymer material (plastic) sheet, or natural material such as wood or bamboo Or a plate or sheet of plastic or metal. The present invention is particularly applicable to “paper” media. Therefore, the embodiment of the present invention described below using the term “paper medium” is not limited to “paper medium”, and includes all other media as used in the present invention.

  Furthermore, “management” as used in the present invention includes not only tracking / processing of information recorded on a paper medium but also processing (newly or repeatedly) for recording information itself on a paper medium. Therefore, the confidential document management system or confidential document management apparatus of the present invention includes all of recording of information itself on a paper medium, tracking of information recorded on the paper medium, and processing. Tracking information recorded on a paper medium means that the information and the user's work history of the information can be confirmed (preferably recorded on time). Processing means generation, taking out, copying, discarding, and the like of a document.

  The confidential document management system of the present invention uses the magnetic ink or toner containing the amorphous magnetic powder according to the present invention described above on a normal paper medium, and attaches the information itself and a management mark (write, record). ). More preferably, the confidential document management system according to the present invention magnetically writes management information to the management mark. Further, with the magnetic ink or toner, the information itself (recorded) attached to the management mark or the paper medium on which the information is recorded, or the management information written on the management mark is fixed to the paper medium. The magnetic powder is magnetically detected.

Therefore, the confidential document management system of the present invention has at least the following excellent effects by using the magnetic ink or toner based on the present invention.
(1) The paper medium itself, the information itself, or those simultaneously can be managed accurately and with high sensitivity.
(2) A paper medium, information, or management information attached thereto can be written, rewritten, and erased.
(3) A normal printing method / printing device, copying method / copying device, and recording method / device using a magnetic head can be used.

FIG. 1 schematically shows the basic concept of the confidential document management system of the present invention. In the present invention, a paper medium (confidential document) on which confidential information to be managed is recorded is first prepared (step 100). Here, the confidential document may be prepared in advance. Alternatively, as shown in steps 10, 11, and 12, information to be recorded and a paper medium may be prepared, and information may be recorded to prepare a confidential document. As a recording method, in addition to a manual writing method, it is possible to use a normal printing apparatus, copying apparatus, or the like. In the present invention, in particular, when recording such information, it is possible to use the magnetic ink or toner according to the present invention in order to record at least a part of the information. In this case, a management mark and / or management information described below is added to the information itself and written.
Next, a management mark is attached to the prepared confidential document with magnetic ink or toner according to the present invention (step 101). After the magnetic ink or toner is fixed on the paper medium, management information is further written to the management mark (step 102). At this stage, the confidential information recorded on the paper medium and the confidential document with the necessary management mark and management information are generated (hereinafter, such a document is referred to as an ID-embedded document, an ID-embedded document). Etc.).
FIG. 1 also shows a step of rewriting or erasing management information once written if necessary (step 103). This is a step of detecting management information at a necessary place when necessary and rewriting or erasing it as necessary in order to enable tracking of confidential documents including users.
One feature of the confidential document management system of the present invention is that the ID-embedded document is magnetically detected (step 104). Here, detection includes detection of confidential information, management marks, and management information recorded on a paper medium separately or simultaneously.
Furthermore, as a final step, the confidential document management system of the present invention performs discrimination processing (and more appropriate processing if necessary) (step 105).

  The management mark will be described in more detail. In the present invention, a “management mark” is attached to at least a part of a paper medium using magnetic ink or toner containing amorphous magnetic powder. The attached “management mark” means that a magnetic ink is applied and fixed in a specific shape at a specific position on a paper medium. Accordingly, the management mark has an amorphous magnetic powder fixed to a portion surrounded by the shape thereof, and is clearly distinguished magnetically from other paper medium portions.

When the magnetic ink of the present invention exhibits a color that is transparent or similar to that of a paper medium, the portion to which the amorphous magnetic powder is fixed and the other paper medium portion may not be distinguished in color, In this case, it can be clearly distinguished magnetically. In addition, when the magnetic ink of the present invention exhibits a color that can be distinguished from the color of the paper medium, the management mark can be clearly distinguished from other parts both magnetically and colorally.
One type of management mark can be attached to a part or all of the paper medium based on its purpose, detection means, detection device, and the like. Two or more different management marks can be attached to the same paper medium. This is because (1) magnetic ink or toner containing two types of amorphous magnetic materials that can be identified and detected is used, or (2) magnetic ink or toner containing the same type of amorphous magnetic materials is used at different concentrations. Is possible.
An example of the management mark is shown in FIG. Here, graphic information 202 is recorded together with character information 201 in the confidential document 200. In FIG. 2, the management mark 203 of the present invention is attached in a band shape that overlaps the character information. In FIG. 2, another management mark 204 is attached to the corner portion of the document in a different circular shape.

  The paper medium 200 to which the management mark 204 is attached includes the case where the paper medium 200 has already recorded the confidential information 201 and 202 and the case where it has not been recorded yet.

  Further, the management mark 203 can be given the same management mark 203 for a plurality of paper media (for example, consisting of a plurality of pages), or can be given a different management mark 203 for each page. . In other words, by attaching the management mark 203 of the present invention, a plurality of paper media can be magnetically identified as a group or separately.

There is no particular limitation on the method and apparatus for attaching a management mark to a paper medium with the magnetic ink or toner of the present invention. As explained above, the magnetic ink or toner of the present invention can be adjusted to have substantially the same or similar properties as conventional inks or toners, and can be used for a predetermined paper medium (paper material type, size, In order to attach to (shape), a normal method / apparatus can be preferably applied as it is or after optimization.
For example, it is possible to prepare the magnetic ink of the present invention as an ink for a normal ink jet printer, and use this to perform ink jet printing on a paper medium with a normal ink jet printer. In this case, the position, shape, and density of the management mark on the paper medium can be easily designed by a personal computer or the like, and then the printing information can be sent to the ink jet printer. Further, two or more kinds of magnetic inks that are magnetically or colorally different are prepared as inks for a normal ink jet printer, and are used for ink jet printing on a paper medium with a normal ink jet printer. Thus, it is possible to attach two or more management marks that can be identified magnetically and / or color on the paper medium.
Similarly, the magnetic ink of the present invention can be prepared as a toner for an ordinary laser printer, and can be used to print on a paper medium with an ordinary laser printer.

  Furthermore, a method of attaching a management mark to a paper medium. As a device, it is also possible to apply a copying method and a copying device. By using the magnetic ink or toner of the present invention in the copying apparatus using the mark of the copy source, the mark copied with the magnetic ink or toner of the present invention can be attached on the paper medium. As described above, it is possible to attach two or more management marks that can be magnetically and / or color-identified on a paper medium based on the shape and color of the copy source mark.

  As one of the preferable management marks in the present invention, a mark attached as all or a part of confidential information can be cited. This is possible by printing (recording) all or part of confidential information on a paper medium using the magnetic ink or toner of the present invention. The confidential information normally recorded on the paper medium is information obtained by visual observation. In this case, the magnetic ink or toner of the present invention is prepared so as to exhibit a visible color. In this case, the management mark is color sensitive information itself and cannot be visually identified (whether it is a management mark or information). On the other hand, of course, it is possible to clearly identify magnetically, and this means that confidential information itself is managed by magnetically managing the management mark.

Further, in the present invention, the detection of the management mark attached to the paper medium is advantageous in the magnetic detection because the magnetic ink or toner of the present invention contains an amorphous magnetic powder as described above. It is. Magnetic detection includes (1) detection based on the presence or absence of amorphous magnetic substance powder in the management marker, (2) detection based on type, (3) detection based on quantity, and (4) detection based on shape. Detection by combination is possible. In addition, when the management mark attached to the paper medium has a visible color, it is possible to detect by combining the above magnetic detection and color detection. For example, it is a case where all the paper medium is color-identified and at the same time a management mark is magnetically attached with the magnetic ink or toner of the present invention.

There are no particular restrictions on the method and apparatus for magnetic detection, (1) detection of presence or absence of amorphous magnetic powder contained in the management mark according to the present invention, (2) detection by type, (3) detection by amount, And (4) A device including a conventional method / sensor capable of detection by shape and further by a combination thereof can be appropriately employed.
It is also possible to use a combination of these two or more detection methods / apparatuses. As a detection method, a method of detecting by contact with a detection device (sensor), a method of detecting by close contact although it is non-contact, or a method of remote detection is possible. It is possible to select appropriately in view of the detection purpose and detection sensitivity. For example, when managing copying of confidential documents, a method of detecting by contact is preferable, and a remote detection method is preferable for managing taking-out of confidential documents.

  When the management mark mentioned above is all or a part of confidential information, it means that the confidential information itself can be magnetically detected by magnetic detection of the management mark. This can be used to manage confidential information (especially, whether or not it is present) when the management mark cannot be detected as a whole, such as when it is partially missing, divided, or folded for some reason. It is valid.

Next, management information of the confidential document management system of the present invention will be described. This is information that is magnetically written in at least a part of the management mark (step 102 in FIG. 1).
Here, the management information means items for managing confidential information recorded on a paper medium. Particularly in the present invention, it is preferable that the management information includes at least one management information of user information, confidential information take-out information, confidential information copy information, and confidential information discard information. More specifically, for example, the following matters are included. (1) ID of the paper medium itself, (2) accessed user ID, (3) accessed date / time history, (4) processing status of confidential information, (5) processing history of confidential information, and the like. The ID of the paper medium itself in (1) is for the purpose of identifying and managing the paper medium itself regardless of confidential information. (4) The processing status of confidential information is the latest information such as whether the confidential information is currently available or prohibited, whether it can be copied or prohibited, and whether it can be discarded or not. (5) is whether or not the confidential information has been copied, its history if it has been copied, and the date and time if it has been discarded. Furthermore, other management-necessary information can also be included.

  Therefore, it is necessary that the management information is written in the management mark so as to be at least readable, writable, changeable, and erasable. In the present invention, since the management mark includes amorphous magnetic powder having excellent magnetic characteristics (particularly excellent soft magnetic characteristics), the management mark is scanned by the magnetic body magnet head, and the management mark is used. It is preferable to write management information by magnetizing and / or demagnetizing a specific portion of the amorphous magnetic powder. More specifically, the amorphous magnetic powder in a specific part in the management mark is magnetized (set to 1) and / or demagnetized (set to 0), and written in binary data representation of 0 and 1. Is preferred. This method has been well known as a magnetic recording method for magnetic recording media.

  Similarly, the magnetic state of the magnetization / non-magnetization (1 or 0) of the amorphous magnetic powder in a specific portion in the management mark written in this manner is again scanned by the magnetic body magnetizing head. Management information can be read out, changed, or erased by magnetizing and / or demagnetizing a specific portion of the amorphous magnetic powder in the mark.

  When the management mark of the present invention described above overlaps a part of the information recorded on the paper medium, the management information of the management mark is written over the information recorded on the paper medium. It will be. This means that management information (for example, user information) is superimposed on the information itself recorded on the paper medium. Similarly, management information once written can be changed and deleted.

  FIG. 3 shows an example of management information written in the management mark. In this example, character information 304 and 302 and graphic information 303 are recorded on the paper medium 300. Further, management marks 301, 305, and 306 are attached in different shapes at different positions of the document. Management information 308 is written in these management marks. In the figure, it is expressed in a striped pattern. This schematically shows the magnetic state of magnetization / non-magnetization (1 or 0) of the amorphous magnetic powder written by scanning a specific portion in the management marks 301, 305, and 306 with the magnetic magnetization head. Is.

  FIG. 4 schematically shows a method of writing the management information of the above example with a normal magnetic material magnetization head. In FIG. 4, the management information 403 is written to the printed management mark 404 together with the inkjet print head 401 for attaching the management mark 404 to the paper medium by the inkjet printer including the magnetic ink of the present invention. An example in which the magnetic material magnetization head 402 can be continuously performed will be described. The paper medium 400 travels in the direction of the arrow and passes through the inkjet print head 401. At that time, a management mark 404 having a predetermined shape is printed using the ink-jet ink containing the magnetic ink of the present invention. The magnetic powder contained in the printed management mark 404 is not normally magnetized, but may be magnetized in advance. The printed management mark is sufficiently dried as it proceeds in the direction of the arrow, and the magnetic powder contained therein is fixed within the shape of the management mark.

  Next, when the paper medium advances in the direction of the arrow, it passes through the magnetic material magnetization head 402. Here, the magnetic material magnetization head 402 writes by magnetizing at least a part of the management mark 404 based on predetermined information. In FIG. 4, the magnetized portion 403 is blacked out and schematically illustrated so as to be distinguished from the non-magnetized portion 404.

The management information written in the management mark can be changed and deleted if necessary (step 103 in FIG. 1). For this reason, it is necessary to first read out already written management information. For this purpose, magnetic recording reading methods and apparatuses using various ordinary types of magnetic sensors can be used as they are or after being optimized. An example of such a reading (rewriting, erasing) device is shown in FIG. FIG. 5 shows an example in which a magnetic material magnetization head 506 for rewriting management information is also provided. The confidential document 500 (the confidential information is not shown) is already provided with a management mark 501 and further has management information 504 written therein. The confidential document 500 proceeds in the direction of the arrow and passes through the magnetic sensor head 505 for reading the printed management information. The management information read (read) here is sent to the computer 510 that is connected to the group via the connection line 509, for example. The computer 510 determines to rewrite or delete at least part of the management information 504 in accordance with predetermined determination criteria and processing procedures. Based on this determination, an instruction for newly written contents is sent from the computer 510 to the magnetic magnetic head for writing 506 via the line 511. The magnetic magnetization head 506 for writing is not magnetized with a portion magnetized at a position to be rewritten by a method of magnetization / non-magnetization, as in the first writing described above. The part is rewritten 502 to become new information 507.
It is also possible to erase already written management information. That is, all the information written in the management mark can be erased by being magnetized or non-magnetized by the writing magnetic material magnetization head 506.

  Next, a method and apparatus for detecting a management mark and / or management information at a necessary place when necessary will be described (step 104 in FIG. 1). One of the features of management of confidential information recorded on the paper medium of the present invention is the management mark written on the management mark and / or the management mark attached with the magnetic ink or toner of the present invention described above. It is to detect the presence of information magnetically. In particular, the detection method according to the present invention is preferably (1) a method of magnetically detecting the presence or absence of an amorphous magnetic material. Furthermore, the detection method according to the present invention is preferably (2) a method of detecting management information written on the amorphous magnetic powder by magnetically reading it. Alternatively, a method of detecting these in combination is also possible. Therefore, the magnetic detection means / device is not particularly limited, and a magnetic sensor based on various ordinary detection principles and a magnetic recording reading method / device using the same are preferably applicable. In addition, these known magnetic sensors and magnetic record readers usually have an optimum operation (for example, detection time, detection sensitivity, resolution, detection distance, etc.) and are suitable for the management purposes of the present invention. It is possible to select a device.

  In the present invention, since an amorphous (soft) magnetic powder having particularly excellent magnetic properties is used, high sensitivity and accuracy can be detected at a further distance.

  Furthermore, in the present invention, first, a magnetic sensor, a magnetic recording reader, etc., which are optimal for detection in a specific management mode (for example, take-out management, copy management, disposal management, etc.) are selected, and the maximum effect is obtained. For use, it is also preferable to prepare an ink or toner containing the amorphous magnetic powder of the present invention. Specifically, the kind of magnetic material of the amorphous magnetic material powder contained in the ink or toner, the shape / size of the powder, the content, and the adjustment of the printing amount can be mentioned.

  The management system of the present invention can include determination based on the finally detected management information and discrimination processing of the confidential document (step 105 in FIG. 1). That is, as described above, after the management mark and / or management information is magnetically detected and read, the read management information is compared with a predetermined processing procedure for determination. , Including performing the following processing means if necessary. There is no particular limitation on the means and method for executing the comparison, determination, and next processing means, and it is possible to perform the method manually or manually using a computer. For example, regarding take-out management by the user from the storage room, detection at the exit gate of the storage room, and further, based on the detected management information, if the take-out is prohibited by comparison and judgment, the gate is closed, a warning is given, It is done. Or, for copy management, management information is detected before copying by a copying apparatus, and if copying is prohibited by comparison and judgment based on the detected management information, the copying apparatus is stopped or warned. Can be mentioned. Similarly, with respect to disposal management, management information is detected before passing to the disposal device, and if the disposal is prohibited by comparison and judgment based on the detected management information, the disposal device is stopped or warned. Etc. These various types of discrimination management may be performed separately or comprehensively by a computer.

  Preferably, in the present invention, each step of the management system of the present invention described in FIG. 1 (that is, management mark assignment, management information writing, detection, discrimination management described separately above), It can be centrally managed using a computer programmed to be managed by an administrator and / or automatically executed.

Next, the confidential document management apparatus of the present invention will be specifically described separately for each of the three modes. However, the confidential document management apparatus of the present invention includes an apparatus that combines these. Furthermore, an apparatus that collectively manages all or some of them using, for example, a computer is also included.
