Description

The invention relates to a sheet material with the Features according to the preamble of claim 1 and writing devices with the features according to the preamble of the An claim 17 or claim 21.

There are various embodiments of flat sheet dimensions material for the production of sheet-shaped writing sheets knows, such sheets provided as information carriers are whose information content is due to the surface brought color particles is intended for optical recognition. The information usually consists of letters ge formed texts or from graphic elements such as wise drawings or the like. The bow is there generally made of paper embedded in a binder Teten cellulose or plastic fibers or from one Plastic film, such as for daylight pro projection is used. The paint is applied by Hand with appropriate writing utensils or by printing directions. The information that can be summarized on a sheet As a rule, content is legible due to the legibility wise smaller letters limited.

With the increasing spread of computers especially in office technology comes from the interplay of optical and  electronic information carriers are becoming increasingly important. Modern, computer-controlled laser and magnetography printers allow a resolution of more than 1,000 dpi (dots per inch, dots per approximately 2.54 cm). The human Au However, ge only recognizes characters that come from a large number of such characters Dots are put together so that they are available de Resolution for a maximum information content not can be exploited. Conversely, it may be necessary optically recognizable information in an electronic informa tion to convert. For this purpose, documents are placed on a so-called called scanner placed and electro-optically scanned. The resulting electronic image of the original shows one high memory requirements. Through a downstream OCR or OMR software (Optical Character Recognition, optical Character recognition; Optical Mark Reading, reading by hand written or printed markings) can by point information read by the scanner in characters or Letter information is converted, which means a reduction in storage requirements. Indeed is this conversion time-consuming and requires today's State of the art, usually a manual correction.

Another way of converting optically recognizable electronic data can be accessed via MICR (Magnetic Ink Cha racter recognition), which involves character recognition by scanning standardized magnetic fonts in a magne table color. In another known method information in the form of a so-called bar code a system of different widths or to each other spaced lines optically recognizable, for example fixed a sticker that can be read over reading pens or hand or Long-range scanners can be scanned. A disadvantage of mentioned systems consists in the immutability of a times printed information.  

The invention has for its object the exchange of improve electronic and optically recognizable data.

The task is carried out by a flat sheet material with the Features of claim 1 and by writing devices with the features of claim 17 or with the features of Claim 21 solved.

For this purpose, it is proposed to coat a surface gene and / or magnetically activated sheet material embed bare particles. The coating has fine cavities spaces, for example in the form of a suitable crystalline Structure and in particular in the form of microcapsules on how they are known from the production of carbonless paper. By embedding the electrically and / or magnetically active Particulate particles in this coating can make this part chen in a joint process together with Beschich tion are applied to the sheet material. Such Coating is suitable for large-area bulk goods, so that inexpensive and large quantities of sheet-shaped sheets can be placed on which both optical and electrical or magnetic information or functions can be deposited. Due to the flat distribution can a high information content on the sheet material so probably on optical as well as for example on magnetic Paths or in combination of them.

The combination of optically readable and magnetically ge Stored information can be from the invention Archable dialogue products are manufactured on where information is stored, changed and queried can.  

The particles mentioned are preferably in the hollow mentioned arranged so that the coating regardless of the In keep the cavities in one process without major modifications tion can take place, as is already the case with large series production supply of carbonless paper is known. The corresponding Flat sheet material is inexpensive in this way adjustable.

Depending on the application, it may be appropriate to do this Cavities or the microcapsule to be adapted. at for example, it may be appropriate to use the microcapsule Fill color formers and share them with the electrical and / or magnetically activatable particles in the coating embedding. It may also be appropriate to ge called particles in their own cavities or microcapsules assign, and for example in a mixture with color image filled microcapsules into the coating. In a further advantageous variant, contains a cavity at the same time the mentioned color former and an electric one and / or magnetically activatable particle. In a before trained training are the mentioned particles as mag netisable particles, for example made of chromium dioxide or comparable materials.

By targeted magnetization of the particles mentioned how in the case of a tape or a floppy disk information in binary Form or be saved in plain text. In particular, if the web or sheet material also has a paper layer around it summarizes, this can also be described or printed become and thereby besides magnetic also optically detectable Carry information. This results in a multitude of advantageous options, especially with regard to Capacity for dialogue. For example, the desired information tion magnetically stored and the track or sheet dimension  Provide additional handwritten material his. It is also possible to have the same information both in writing as well as magnetically on the sheet or sheet mate rial, resulting in the possibility of direct le sens by a viewer and reading by a suitable nete magnetic scanning device for feeding into a Computer results.

In particular, a simple duplication is example using a slightly modified magnetograph phiedruckers possible, by means of which without Toner powder a direct magnetization of the embedded Particle is enabled. When using a Toner powder can simultaneously get the information you want a work process both magnetically and optically be applied in a recognizable manner. Training with magneti sizable particles and color former-filled microcapsules, as known from carbonless papers, the Capsules burst under the influence of pressure or heat and the Release the included color former. The initially colorless The color former then encounters a color developing material which in the coating with the cavities or surface on the underside on a copy sheet is brought. Through the interaction of the color former and the color-developing material creates a visible through font. In conjunction with a suitable device he This gives, for example, the possibility of ent to describe speaking arch initially only magnetically and following a dialog process with various query and changes or corrections the saved In make formation visible.

The sheet material according to the invention allows next to the Labeling option described above also other  Handling options as described by ordinary benen sheets of paper are known. For example, a Lo stitching, stapling, filing and archiving and also gluing or glue binding as with paper sheets possible. This is the bo gene material, which is typically in an elongated form is manufactured and wound into rolls, advantageous in Form of an arch with a standardized base area ins especially trimmed in A4 format so that this in common printers, copiers and so on edited and in standardized file folders can be archived. there such a sheet or sheet material is advantageous in Subdivisions divided, of which at least one as a reading / Writing area is formed. Another area can only be used to attach staples, Perforations or a glue binding can be provided without doing so affect the stored magnetic information. The read / write area is expediently by a printed mark marked so that the user without Difficulty seeing where, for example, a ge can make their own perforations.

In an advantageous variant, the sheet material has conductor tracks which can be printed from a conductive ink and expediently consist of electrically conductive particles embedded in the coating mentioned. The particles can be, for example, a metal powder and / or the above-mentioned magnetizable particles, which fulfill a double function as magnetic data storage and as an electrical transmission element. The sheet material is expediently divided into a plurality of reading / writing areas 12 , which are each connected to a conductor track. In this way, structures in the manner of a circuit can be realized in which, for example, the magnetic information of an individual read / write area can be queried or changed at a remote location via a conductor track.

Suitable particles to be embedded in the coating are also microchips, such as those used in so-called "Smart labels" are used. Such is a microchip expediently connected to the above-mentioned conductor tracks and allows, for example, an evaluation of the individual Read / write areas of filed magnetic information. In an expedient further development is on the sheet material an antenna for data exchange with the activatable part Chen applied in particular by printing. Thereby he the area of application of the sheet material in which the stored information, for example when walking through through a manufacturing process at different points various means appropriate to the situation and / or can be changed. The sheet material mentioned can, for example, be guided through a scanner-like device be, the magnetic information can be scanned. On Places where such direct access is not possible, can the magnetically stored information on the ge named antenna in connection with a microphone, for example chip are queried, the typical reception distance is in the range of one meter. Are in the process longer query distances are required the magnetic information, for example, be on the above written microcapsule color former technology made visible and optically scanned. For example, the Infor mation magnetically and optically applied as a bar code, the optically recognizable bar code via a long-range Scanner can be read within a range of up to approx. 10 m.

Products from the sheet material according to the invention as in for example copy sets, forms, labels, freight  Letters, ballot papers and much more are capable of dialogue and thus versatile. The sheet material is on non-impact Printers can be printed in multiple layers, the magnetic Information corresponds to the printed information or can also deviate from this. With an "intelligent" freight letter, for example, the magnetic information in the Course of the transportation process and an accompanying one Dialog process adapted to the current status and for example, be made visible during delivery.

For applying the magnetic information to a sheet size suitable with embedded, magnetizable particles a writing device that uses a magnetography has head. Using such a magnetography writing head, as known from magnetography printers is magnetized along its longitudinal axis with pinpoint accuracy bare particles can be conditioned. Through a relative movement supply of the sheet material to the magnetography writing head across its longitudinal axis is every single point on the sheet mat rial comparable to a laser printer or photocopier in desired magnetizable. These are very high Write speeds at a very high da tendent density achievable.

Are in an appropriate design of the writing device two magnetic recording heads against each other with a zwi aligned gap through which the sheet mate rial is feasible. Through mutual alignment can have a high magnetic field strength in the gap and thus a reliable magnetic conditioning of the magnetizable Particles can be obtained in the sheet material. It is useful there provided with a downstream magnetic reading unit, by means of which the magnetic information on the sheet mat rial can be read. This makes it a combination device  created for writing and / or reading. In particular, can with a suitable training the magnetically written Information from the downstream magnetic reading unit immediately checked for errors in the magnetic data storage the. This contributes to data security in particular if the information is initially only stored on magnetic Paths without visual visualization and thus control possibility.

The writing device described above is advantageous as an expansion unit for a conventional printer educated. This allows existing printing machines or also affordable, mass-produced workplace printers are expanded so that the well-known data processing processing with optically readable information with low access costs for the magnetically stored information is continued. In an appropriate combination of writing device and training of the sheet material can be great Quantities of sheets inexpensively optically without toner, ink, etc. and labeled magnetically legible.

Furthermore, it is proposed to use a writing device in Form a hand-held pen, the one Has magnetic tip. For example in connection with self-inking paper can be hand-held with such Writing device comparable to a pencil or Ku Gel pens written on this paper so that they are legible be, by the magnetic tip dis same information also magnetically applied for automatic data acquisition becomes. With such a writing device can for example ballot papers, bank orders or the like from egg handwritten with the appropriate sheet material, which then in large quantities via a magnetic Reading device reliable and at high speed  can be evaluated. The pen-shaped writing device Depending on the application, a pure magnetic tip or a combination of magnetic tip and for example one Have ballpoint pen refills or the like.
