Embodiment Construction

[0055] FIG. 1 shows a printed sheet 1 cut from a printed sheet material 2 with a washcoat 30 , which is divided into two subregions 10 , 11 . The subregion 10 extends along a long edge 28 and has a hole 29 . The other partial area 11 forms a read / write area 12 and is identified by a printed marking 13 . The printed sheet 1 can be of any size, but in the example shown it is of DIN A4 size.

[0056]FIG. 2 shows in an enlarged sectional view a cross-section through a copy set 15 with the printed sheet 1 of FIG. Cardboard or cardboard can also be used. A coating 4 is applied to the carrier layer 30 , in which the cavities 3 and electrically and / or magnetically activatable particles 5 are embedded. The cavities 3 can be formed by a suitable crystalline structure of the coating 4 , in the example shown the cavities 3 are micro-cavities 6 which are filled with pigment components 7 . The activatable particles 5 may be carbon particles or other conductive particles, in the example ...

Abstract

In flat strip material, for making sheets for registering information, which has a coating containing fine cavities on at least one side, particles (I) that can be activated electrically and / or magnetically are embedded in the coating. Independent claims are also included for (a) equipment for writing on this material, which has a magnetographic writing head for dot-accurate magnetic activation of the magnetizable particles; (b) equipment for writing on this material, which is in the form of a hand-held stylus with a magnetic tip.

Description

[0001] The application date is May 19, 2001, and the application number is 01810511.4 (international application number is PCT / EP 01 / 05754) entitled "Plane material (especially printed sheet or web) and writing device for this material "A divisional application of the application. technical field [0002] The invention relates to a flat printed sheet material and a writing device for said flat printed sheet material. Background technique [0003] Various embodiments of planar printed sheet materials are known for producing sheet-shaped printed sheets, where such printed sheets are defined as carriers of information whose information content is made visually visible by means of pigments printed on the surface. distinguish. Information is usually written in letters or in images such as drawings. In this case, the printed sheet generally consists of paper with cellulose or plastic fibers embedded in a binder or of a plastic film (as it is used for solar projection). Color pr...
