A positioning system includes a slide support, on which is mounted a positioning slide, which can be driven to perform a positioning movement in a positioning plane with the aid of drive gears of the slide support, wherein the positioning plane is defined by a Cartesian x-y coordinate system. The drive gears are represented by at least one x-drive gear, which can cause a positioning movement in the x-axis direction, and at least one y-drive gear, which can cause a positioning movement in the y-axis direction. The drive gears are in engagement with a driven toothing structure of the positioning slide, which includes a plurality of driven teeth distributed in a punctiform arrangement in a regular two-dimensional tooth matrix. Although the drive gears are short, the positioning system facilitates a traverse of the positioning slide within a large positioning area. |

1. A positioning system comprising at least one positioning slide which is variably traversable and positionable relative to a slide support of the positioning system while performing a positioning movement in a positioning plane defined by a Cartesian x-y coordinate system, wherein the slide support comprises at least one y-drive gear which can be driven by drive means of the positioning system to perform a drive rotary movement about an axis of rotation parallel to the x-axis of the coordinate system and at least one x-drive gear which can be driven by drive means to perform a drive rotary movement about an axis of rotation parallel to the y-axis of the coordinate system, wherein each y-drive gear and each x-drive gear has a drive toothing at its outer circumference and wherein the positioning slide has a driven toothing structure with which it is simultaneously in tooth engagement with the drive toothing of at least one x-drive gear and at least one y-drive gear during the positioning movement and can be driven to perform a positioning movement in the x-axis direction of the x-y coordinate system by rotating the respective x-drive gear and to perform a positioning movement in the y-axis direction of the x-y coordinate system by rotating the respective y-drive gear, and wherein the driven toothing structure of the positioning slide comprises a plurality of driven teeth distributed in a punctiform fashion in a plane parallel to the positioning plane, which are placed in a two-dimensional tooth matrix at the intersection points of mutually perpendicular x-grid lines and y-grid lines of an imaginary cross grid, wherein at least several of the driven teeth of the tooth matrix are capable of coming into tooth engagement with both the at least one x-drive gear and the at least one y-drive gear during the positioning movement of the positioning slide. |
