Abstract
A focus adjustment apparatus () for a code reader () is provided which has an objective () having at least one lens and a drive () with a cam plate () for the positional adjustment of the objective (). The objective () is supported in a parallel guide () having a coupling unit () for the coupling of the cam plate () so that a rotational movement of the cam plate () adjusts the position of the objective () in the parallel guide () with a parallel shift of the objective plane. The coupling unit () has a press-on element () for the play-free coupling of the parallel guide () to the cam plate () and a counter-bearing element () between the press-on element () and the drive () for relieving the drive () from the press-on element ().
