Definitions

  • the invention relates to a device for describing a tilted image structure on a base body, in particular on an identification card, according to the preamble of claim 1.
  • a device is formed with a laser light source having a control device for selectively changing an exit angle of the laser light from the laser light source, and a recording for the body.
  • the invention further relates to a method for describing a tilted image structure on a base body, in particular on an identification card, according to the preamble of claim 15.
  • laser light is generated with a laser light source, wherein an exit angle of the laser light from the laser light source is selectively changed by means of a control device ,
  • tilt images As a security feature for identification cards, such as bank cards and official documents such as passports, so-called tilt images are known. Such tilt images, which may also be referred to as “wobbly images" and which may be designed in particular as lenticular images, show a different image depending on the viewing angle ⁇ , for example + 15 ° or -15 °.
  • a tilting image can be based on a transparent line grid of parallel cylindrical lenses or prisms which are applied to the surface of the identification card. Behind this grid structure, an optical information structure is arranged. Depending on the viewing angle, the grid structure focuses on another part of the information structure so that different images are visible in different viewing directions.
  • a tilting image when using cylindrical lenses, can also contain more than two individual images.
  • the tilting image can also vary continuously with the viewing angle and convey a three-dimensional image impression.
  • the card For the production of tilt images, it is known from the prior art to first emboss the lenticular grid, in particular the prism lens grid, onto the transparent cover layer of the card. Then the card is inserted in a laser marking machine. In this labeling machine, the card usually passes through several stations, where it can be labeled, among other things with text and / or image information.
  • CLI changeable laser image
  • MLI multiple laser image
  • the card is then tilted in an usually separate mechanical tilting station by an angle ⁇ .
  • a first image is applied through the lenticular structure with a laser.
  • a tilt by the angle 2 x ⁇ in the opposite direction, so that the card is now tilted by the angle - ⁇ .
  • the second image is then applied through the lens structure by laser.
  • the angle ⁇ may be 15 °, for example.
  • the "wobbly picture" is created on the labeled card.
  • the viewer must also adjust an angle of approximately + ⁇ or - ⁇ in this image to see one or the other lasered image with the maximum contrast.
  • a method and apparatus for describing a cylindrical lens image are known from EP 0 219 012 A2 known.
  • This document teaches a laser marking method in which the card is tilted by a certain angle after writing a first image information.
  • the EP 0 219 012 A2 be provided to change the angle of incidence by introducing prisms in the beam path.
  • this procedure can also be comparatively time-consuming and cumbersome because a comparatively large mass has to be moved with the prisms. If a large number of cards are to be labeled, then each one must be labeled Marking process, the prisms may be adjusted several times, which may limit the throughput.
  • the object of the invention is to specify a device and a method for writing a tilt image structure which, with low mechanical outlay, allow a particularly high throughput of the structures to be inscribed.
  • the device according to the invention is characterized in that two deflecting elements for the laser light are provided in the beam region of the laser light source, wherein the deflecting elements are arranged such that deflected, in particular reflected laser light of the laser light source in each case at a different angle of incidence on the tilt image structure of the recorded on the recording Body falls.
  • a basic idea of the invention can be seen in the fact that the angle of incidence of the laser light on the tilted image structure is not changed by tilting the base body as known from the prior art, but rather by variation of the beam path.
  • the invention is not written directly from the laser light source on the body, but on the detour of the deflection.
  • These deflection elements are arranged such that the angle of incidence of the laser light deflected on them lies on the base body in the area required for the generation of the tilt image.
  • the mechanically complex tilting station can be omitted and the tilting image can therefore be applied comparatively quickly.
  • no additional movable optical elements are required which could affect the throughput rate. Rather, the different tilt angles are generated in the labeling by varying the beam path on the part of the laser light source, which is anyway designed to describe the tilt image structure with a variable beam path.
  • the tilt image structure may be, for example, a laser-writable information carrier structure on which a lenticular grid structure is provided.
  • This information carrier structure is described according to the invention through the lenticular structure with laser light.
  • the control device suitably has a laser scanner, which may, for example, have two movable mirrors for adjusting the beam path in two spatial directions.

  • the surface normal can be specified in particular relative to the labeling level.
  • At least one deflection element in particular both deflection elements, is or are designed as a deflection mirror.

It is particularly preferred that the two deflection elements have the same distance to the tilting image structure of the base body received on the receptacle. This further simplifies image formation. Alternatively, it can also be provided that the two deflection elements have a different distance from the tilting image structure of the base body accommodated on the receptacle. As a result, the dimension of the device can be adapted to geometric specifications.
  • a particularly versatile device is given by the fact that between the deflection elements, a free space is formed, which allows direct irradiation of the base body with the laser light of the laser light source.

  • the size of the deflection elements and / or their distances to the labeling level on the base body and / or the lens of the laser light source can be selected depending on the specific application so that a maximum labeling field directly, ie without deflection at the deflection, can be labeled.
  • a further preferred embodiment of the invention is that at least one of the deflecting elements is pivotable.
  • a pivotability can be given in particular about an axis which is perpendicular to the optical axis of the laser light source and / or to the surface normal of the lenticular structure. For example, by pivoting the baffles by a few degrees, the exact angle, e.g. Set exactly for the center of the tilt image structure field.
  • at least one adjusting screw can be provided for pivoting the deflecting element.
  • a further preferred embodiment of the invention consists in that a focus of the laser light source lies behind the deflection elements in the beam direction.
  • This embodiment is particularly advantageous in the case of small tilt image structures and can make a planar field objective, in particular a so-called F-theta optics, superfluous.
  • F-theta optics in particular a so-called F-theta optics
  • a focus lying behind a deflecting element can be understood in particular to mean that the focus lies on the side of the element facing away from the laser light source in the beam path.
  • a preferred embodiment of the invention is that a total of four deflection elements are provided.
  • two of them are arranged to write a first sub-image of the tilt image structure and the two remaining to write a second sub-image of the tilt image structure.
  • two of the four deflecting elements are thus arranged in the current beam path during each writing process.
