| 20120029681 | IMAGE ENGRAVING DEVICE - The present invention provides an image engraving device for engraving a special composite paper or a thin plastic plate by moving an engraving needle and a target plate to be engraved relative to each other such that the engraving needle scans the target plate, the image engraving device operating only if a license code is input and is certified correct. The image engraving device has a license code input part for inputting a license code, a license code certifying part certifying whether the input license code is correct or not, and a controller controlling to allow the image engraving device to operate only if the license code is certified correct. With this configuration, the image engraving device solves the problem. In order to secure the certification of the license code, an engraving needle driver and a target plate driver are provided certifying parts, respectively. The operation of the certifying parts is hard-coded to prevent the image engraving device from fraudulently certifying. This configuration allows the authenticated image engraving device to operate, and it secure reliability of engraved plates that are target plates having been engraved. | 02-02-2012 |
| 20100260973 | IMAGE CARD, IMAGE ENGRAVING DEVICE AND IMAGE ENGRAVING METHOD - In an image card where an image is formed on a thin plate made of special synthetic paper or plastic by engraving by sweeping the plate with the engraving needle through relative movement of an engraving needle and a plate, it is impossible to form a hidden image which can be viewed when a viewpoint is changed or form an image formed by watermark engraving and the hidden image within the same plane. A hidden image is formed on an image card by engraving while angles of stripes of striped patterns are changed in response to shading of an image. Further, an image engraving device is provided with a rotary driving unit, and engraving is performed in a state that an extending direction of striped grooves of the hidden image and a forming direction of the engraving are made equal, so that a wall face of a groove is always formed by the same side face of an engraving needle and undulation does not occur on the wall face of the groove. Similarly, a shape of a bottom face of the groove is made even. As a result, precision of the hidden image is made high and an effect as the hidden image is further improved. | 10-14-2010 |
