Abstract: An articulated arm for the alignment or a capturing device for optically capturing an object to be placed on a support surface, has—as a conventional double parallelogram arm—a base part, a top part, an articulate part and two pairs of rods which connect the base part or the top part to the articulated part. The articulated arm furthermore has a shaft which is rotatably fastened to the top part and has an operative mechanical connection to one of the rods pivotably fastened to the top part. This operative connection results in a rotation of the shaft relative to the top part on pivoting of the rod.

Abstract: An articulated arm (1) according to the invention, for the alignment of a capturing means (2) for optically capturing an object to be placed on a support surface (3), has—as a conventional double parallelogram arm—a base part (4), a top part (7), an articulated part (10) and two pairs of rods (5, 6, 8, 9) which connect the base part (4) or the top part (7) to the articulated part (10). In contrast to the prior art, an articulated arm (1) according to the invention furthermore has a shaft (11) which is rotatably fastened to the top part (7) and has an operative mechanical connection to one of the rods (9) pivotably fastened to the top part (7). This operative connection results in a rotation of the shaft (11) relative to the top part (7) on pivoting of the rod (9).
