Optoelectronic measuring device that comprises a read head (1) and at least two carrier bodies (3) joined to each other, each carrier body (3) comprising a longitudinal inner surface on which the read head (1) runs when it moves. The device (100) also comprises at least one additional element (4;47,48) for each carrier body (3), each additional element comprising a reference (400) arranged at a specific reference distance in relation to the inner surface of the corresponding carrier body (3). The reference distances are substantially equal for all the additional elements and the corresponding carrier bodies (3), the references being aligned with each other with the result that the inner surfaces of the various carrier bodies (3) are aligned. |
