FOCUS ADJUSTMENT APPARATUS FOR A CODE READER |
摘要 |
A focus adjustment apparatus (10) for a code reader (100) is provided which has an objective (12) having at least one lens and a drive (18) with a cam plate (16) for the positional adjustment of the objective (12). The objective (12) is supported in a parallel guide (14) having a coupling unit (32, 34) for the coupling of the cam plate (16) so that a rotational movement of the cam plate (16) adjusts the position of the objective (12) in the parallel guide (14) with a parallel shift of the objective plane. The coupling unit (32, 34) has a press-on element (32) for the play-free coupling of the parallel guide (14) to the cam plate (16) and a counter-bearing element (34) between the press-on element (32) and the drive (18) for relieving the drive (18) from the press-on element (34).
