Description

Detailed Description of the Invention                           Documents, especially securities                                 Technical field   The present invention relates to documents, in particular document sheets, preferably securities (eg banknotes). , Checks, etc.).                                 Background technology   The warranty certificate may have a thread or tape embedded in the certificate as a warranty element. Yes (German Patent Publication No. 3906695). In this case, the assurance element is Has an opaque cover layer that extends across the element, including holes in the shape of power symbols and patterns It can be composed of a transparent synthetic resin film. In addition, the assurance element should have a range matching the hole. Color and / or luminesces in the enclosure and provides proper assurance of the warranty and opaque coating layer. To distinguish symbols and / or patterns in the form of color contrasts under bright conditions Including substances for Thus, the symbols, patterns, etc. can be seen in the transmitted light. , Visually and / or mechanically.   In the area of securities, further color reproduction with improved quality and equipment. Especially when the machine becomes widespread and makes general, general observations in social life, The problem of giving a copy that is almost indistinguishable from the original appears. Therefore, It is impossible to copy the securities, or at least it can be clearly distinguished from the original. Increasing efforts are being made to develop ways to provide a copy of the same. That is, already When illuminating light onto at least a part of the surface of a confidential document, a wave different from the wavelength of the illuminating light It has been proposed to coat long light emitting materials. Proof prepared in this way When the book is illuminated with the illumination light of the copier and the detector receives the emitted light, the detector Copy Interrupting or eliminating at least one step required to copy the original certificate on the machine Can generate a signal that can be used for. In this case, it is difficult to prepare the certificate, and The overturned material changes or flakes off, so the warranty function is no longer fulfilled .                                Disclosure of the invention   The present invention presents a method of avoiding the above drawbacks.   A transparent film (for example, a synthetic resin film or It is proposed to provide the document with at least one window covered by (transparent paper). In the case of an experiment for copying a document configured in this way, a color copying machine should be installed at the window. In the case of, a stain of the corresponding color tone or in the case of a black and white copying machine, a dark stain occurs, Thus, the document can be easily verified as a copy immediately. The shape of the window (contour) depends on It may be circular, oval, polygonal, etc. However, window-shaped The letter may be a symbol relating to the nature of the document (eg, the value of the document).   The film or transparent paper passes through the window and is embedded in the paper (sheet) outside the outline of the window Is preferred. The transparent film or paper should have a flat surface, i.e. You can also pack it in the window so that there is no step in the outline.   Another embodiment of the document according to the invention is that a transparent film or paper is placed on top of the document. And / or the bottom surface is fixed so as to cover the window.   Documents (securities) are made from normal window-coated paper layers and film or transparency. It can be configured as a sandwich including a second layer including Film covering windows The paper covering the window must be imprinted or pasted in the area of the window, preferably machine-readable. A supplementary warranty symbol may be provided with it. The present invention will be described in detail below with reference to the drawings.                             Brief description of the drawings   FIG. 1 is a plan view of a first embodiment of a document according to the present invention, and FIG. FIG. 2b is a cross-sectional view taken along the line II-II of the figure, FIG. Is a drawing showing a method of a sandwich structure, and FIG. 3 is an embodiment of FIGS. FIG. 4 is a sectional view corresponding to FIG. 2 of an embodiment different from FIG. FIG. 5 is a cross-sectional view corresponding to FIG. 2 of an embodiment different from that shown in FIG. 1 is a drawing showing a structure of a normal paper layer combined with a transparent film or a paper layer.                      BEST MODE FOR CARRYING OUT THE INVENTION   In the drawings, in the case of the illustrated embodiment, a document sheet with an oval window through the document is shown. The sheet is indicated by 1. The window 2 is covered with a transparent film 3. The film is It is preferably composed of synthetic resin. Synthetic resin film 3 or transparent paper layer is a window Outside of 2, the synthetic resin film 3 or the transparent paper layer is embedded in the document 1. You.   In the case of the embodiment of FIG. 3, the transparent film 3 fills the document 1 (security note) and thus , The contour of the window 2 has no steps and the document is flat over its entire surface.   In the case of the embodiment of FIG. 4, the window 2 may be on the document 1 on the top or the bottom of the document 1, for example It is covered by a film 3 or transparent paper which is fixed by adhesion. this In this case, the film 3 or transparencies are spread over the entire surface of the document, i.e. to the edge of the document. Can be extended by. In addition, the window should only be on one side of the document with the film 3 or transparent. It can be covered by a light paper layer. In this case, the film or transparent paper layer, Provided on the top or bottom of the document (Fig. 5).
