Abstract

A device for optically capturing objects has a support surface ( 1 ) for an object, a light source ( 4 ) and a capturing means ( 5 ) for capturing the positioned object and for converting the image of the captured object into electrical signals. The light source ( 4 ) and the capturing means ( 5 ) are each arranged in a specific position relative to the support surface ( 1 ). The support surface ( 1 ) has a section ( 6 ) provided with a curvature determined by the two positions. Said section is arranged so that illuminating beams ( 2, 3 ) emitted by the light source can be reflected by the support surface ( 1 ) in the direction of the capturing means 5 substantially only in a diffuse manner.

Claims (10)

1. Device for optically capturing objects, comprising:

a support surface ( 1 ) on whose first side an object can be placed,

a light source ( 4 ) which is provided for emitting illuminating beams ( 2 , 3 ) in the direction of the support surface ( 1 ) and which, in a first position, is arranged relative to the support surface ( 1 ), and

a capturing means ( 5 ) which is provided for capturing the object placed on the support surface ( 2 )- and optionally for converting the image of the captured object into electrical signals—and which, in a second position, is arranged relative to the support surface ( 1 ),

wherein the first side of the support surface ( 1 ), on which the object can be placed, faces the illuminating beams ( 2 , 3 ) and the capturing means ( 5 ), characterized in that the first side of the support surface ( 1 ) has a flat region ( 16 ) and—adjacent to this—a section ( 6 ) which is provided with a curvature determined by the two positions and which is arranged in such a way that the illuminating beams ( 3 ) are reflected by the section ( 6 ) in the direction of the capturing means substantially only in a diffuse manner.

2. Device for optically capturing objects according to claim 1 , characterized in that the section ( 6 ) has a curvature only in the direction of the capturing means ( 5 ).

3. Device for optically capturing objects according to claim 1 , characterized in that the curvature corresponds—in perpendicular cross-section—to a segment of a conic section ( 20 ).

4. Device for optically capturing objects according to claim 1 , characterized in that a back-lit, discrete slide capturing region ( 7 ) having a mechanical, point-discrete positioning aid ( 8 ) for the accurate positioning of at least one first slide ( 9 ) is coordinated with the support surface ( 1 ).

5. Device for optically capturing objects according to claim 4 , characterized in that a back-lit preview region ( 10 ) is provided which is adjacent to the slide capturing region ( 7 ) and with which a mechanical, line-discrete positioning aid ( 11 ) for positioning at least one further slide ( 12 ) on a line is coordinated.

6. Device for optically capturing objects according to claim 4 , characterized in that the capturing means ( 5 ) is rotatable relative to the support surface ( 1 ), and the capturing means ( 5 ) can be repetitively oriented with the discrete slide capturing region ( 7 ) by means of a locking element.
