Abstract

Abstract: The present invention relates to the installation of effective optical diffraction net safety elements and an apparatus for testing such elements. Currently, the use of three-dimensional holograms has increased. Other security elements are broadly effective optical diffraction technology to protect certificates, banknotes and other bank papers from counterfeiting. According to the invention, the active diffraction optical element features a discontinuous metallic layer and/or layered metallization and/or layered regions of different planes providing a required electrical information code. The device includes a capacitive scanner that includes a large number of transmitting electrodes arranged side by side and a receiving electrode running parallel to that arrangement side by side. The scanner is placed in a document-processing machine in such a way as to allow the optical-mechanical sensors normally available in document-processing machines to actuate the test device according to the invention. The energy of the corresponding transmitting electrode is over-capacitively coupled if there is electrical conductivity between the transmitting and receiving electrodes. The signal response at the receiving electrode is converted into appropriate signal images. We depend on the indicative images on the structure of the metallized layer of the effective optical diffraction safety element. An electronic evaluation system down from the receiving electrode compares the reference images of the test target with the appropriate reference signals. Figure 22, 14

Description

D Installation of an effective diffraction security element and apparatus for checking such elements Full Description BACKGROUND The present invention relates to the installation of diffraction security elements and apparatus for checking such elements. So far, documents with clad optics have been examined, especially stereoscopic figures; It is checked 0 by sophisticated visual inspection technology. During this process, the elements to be examined must be carefully positioned. And the whole process lasts for a long time so that these inspection methods are not used in high speed processing machines. For example, it is not possible to test documents with what is known as TENE SUEY inside the document processing machine, as it operates at a high speed. For example Jl) filed in US patent application ©785778; Description of the device for checking characteristic 0 for documents with electrically conductive bands. with the help of a capacitive first element that extends the width of the document to be scanned; the order of their placement above the said element; The charge is converted into one of the electrically conductive energies. While moving documents to be examined, the electrically conductive charged band passes under another element extending the width of the document through which the charge is dissipated. And during this process; Generate decoding circuit and evaluation function of a modular signal. ve This device and the applied functional principle take on relatively large electrically conductive bands extending the width of the document to be examined; As long as the amount of charge transferred decreases to a large extent in the case of relatively small areas. It is impossible to examine a group of conductive bands at the same time, as is the estimation of geometric shape and size; In precisely cut design. European patent application 175970al3 is also filed for the examination of the results of electrically insulating properties by varying the voltage of paper materials; The material being examined is moved between pairs of plates in a row of capacitors of specific composition. A change in the dielectric properties results in a change in the potential of the receiving electrodes. Signals are amplified and rated individually. In the case of this machine, which operates on the basis of examining the electrical insulating properties of the paper material; especially watermarks; All capacitors are simultaneously fed the frequency of the device oscillator from which WDA can occur

Connect adjacent channels. If a larger distance is chosen for the capacitors so that this shortcoming is avoided; The degree of accuracy that can be obtained is reduced. Therefore, only non-smooth textures can be recorded. In order to deal with occasional problems above the receiving layers of the capacitors; Only a relatively low total change frequency can be allowed and this sets low scan speed limits. No 0 such a tool can be used in overclocked clad processors due to structural reasons. EP No. 7,879,778 describes a combined process for printing and forming an icosahedron and applies the reflected material either to the hologram itself or to surrounding material. The material is removed outside the anthropomorphic figure either by scratching or it is left so as not to damage the carrier layer. German patent application 77,497,159 describes a method and means of testing for checking the reliability of secured 0-hologram identity cards. The OVD is re-done and a visual examination is performed. This method is not suitable for a quick check; effective; And personal. The European patent application EYRE describes an apparatus for the production of certain models which are examined with oll beam, mirror and lens systems; and photodetector. In this case, the economic cost will rise. It may increase if the goods are inspected without sorting. In order to avoid pre-screening 1 a multiple order of a documented testing system is required. Demineralization is also common in diffraction security elements; To obtain visual effects that have been examined so far only through visual means. And as disclosed in the following US documents OVAAATY and 4 OVA Document Security Elements Mold in 3D JIS; The same security threads that contain metallic layers benefit reflectivity and allow the security threads to appear opaque in the light that is transmitted. by overlapping metal- and non-metallic bands in a zigzag pattern and a columnar pattern; Lighting patterns that have shifted phase are perceived in the transmitted light. A general description of the invention that is one of the objectives of the invention; remove prior art defects and provide installation of diffraction vo security elements; in particular 017705 devices or holograms; or motor forms that can be quickly examined; This is done through personal efforts and of low quality. as well; One of the objectives of the invention is to provide a device for scanning documents containing such security elements. maybe

The use of the device in both document processing machines and in hand-held testing devices to examine documents with diffraction security elements. According to the invention; This target is obtained by a device that has the attributes of claim 1 and a method that has the attributes of claim AY

m. The use of holograms and other diffraction-enabled security elements to secure certificates, other security papers, and securities will increase the more frequent need to prevent the occurrence of Lays and documents of this type; It is Ste stock DM version 19497 which contains in addition to the electrically conductive security chip a diffraction security element in the form of a moving figure. The ability to scan quickly represents an AT security stage in estimating which items

0 works with diffraction as a feature to prove its authentication. Diffraction elements consist of a layer that has been treated with metal. This metal-treated layer is electrically conductive. The electrical conductivity varies with the thickness of the layer. According to the invention the diffraction element contains a non-continuous annealed layer and/or partially metallic layers representing specific electrical encoding of information. In this case, the transformation shape balances the geometric shapes, especially the lines; gridlines; spaces;

Led and circuits; which are arranged regularly and irregularly. The layer in which the metal has been partially inserted contains; Which is arranged to be placed on top of a carrier layer a set of demineralized sections. A non-contact metal layer contains segments with variable electrical conductivity. The device contains a capacitive scanner. This scanner includes a large group of conducting electrodes that settle one next to the other, and there is a receiver electrode parallel to this

ve class. According to the invention the placement of the scanner in the dalled AT document is arranged so that optical or mechanical sensors activate the processing present in the conventional document. In order to reduce detection and measurement errors; It is preferable to use a holder for a sensor. This mount is compatible with all sensors used for testing. The distances between the sensors are reduced in this way; The sensors are always arranged in a specific position.

“The single window electrodes are steered by electrical energy through a time shift by means of an electronic actuator unit with full frequency change in the rate of KHZ The actuator unit contains

and electronic; As a major component 0 on a multicontact, an oscillator to transmit power to the conductive electrodes, and an oscillator to power the multicontact along with the power supply. In the case of electrical connection. In exchange, energy passes from the transmitting electrode that has been moved and signaled in the form of a capacitive link between this transmitting electrode and the receiving electrode. if there is no electrically conductive feature; No electrical transfer will occur between the guiding electrode and the receiving electrode. The wavy pattern of the signal over the receiving electrode transforms into a corresponding signal pattern. The signal model depends on the composition of the metal-introduced layer of the diffracted element. If the diffraction elements have a non-bonding metallic layer, this means that a group of sections of the metallic layer have different conductive capabilities. The electronic evaluation unit (0) tracks the received electrode and compares the signal pattern from the samples to its counterpart from the reference signal. Basically, the electronic evaluation unit includes a power source; an amplifier and re-embedder; comparative; a microprocessor with memory; Purifiers to stop unwanted external signals. bookmark templates stored; In addition to the in-memory microprocessor programs which 1 are compared to the scanned signal pattern of the document being scanned. As long as the scanner covers the width of the entire document each electrically conductive feature is covered by the device according to the invention. A comparison with reference models provides a categorized signal for further processing. So; For example JB The document whose forgery is detected can be sorted by A check which is turned off. In order to reduce undesirable effects gd.vy. the sensor holder is connected to a circuit board in a compact manner that holds the motor and ERUs. The entire inspection machine is housed within the document processing machines so that the required space remains relatively small. Electrodes are arranged above or below documents in document processing machines in such a way that scans can be obtained. This is done with the help of belts for example or in the range of diffraction machines; So that the document is compressed against ve the receiving and transferred electrodes during transport. Speaking of adjusting the electrode arrangement; In the present invention is the arrangement of placing an extended conducting electrode along an array comprising a large number of receiving electrodes closely located next to each other. In this case the receiving signals are processed by multiple communication units. agree ',

The process of purification of the receiving and other transport electrodes is characterized by a large number of receiving and transmitting electrodes arranged next to each other and/or in a row. Both receiving and playback signals are processed according to multiple and non-multimedia modes of communication. For the purpose of using portable devices, the said device does not contain a Blas device with an image corresponding to document or scanner transmission; Its function is equivalent to the transmitting device in copiers, and the optical image is fed to the scanner and fax machines. And amending that; device is provided; performed by stopping elements; Determine the location of the scanner and the pursuit of the inspection device in accordance with the invention related to the document.
