ABSTRACT:
A locking device for the scanning mechanism of a laser scriber of the type having a stationary laser head comprises an actuator operable in association with the table drive mechanism and a presser element operable under the action of the actuator to move one of the scanning tables against the guide structure provided for the table to prevent oscillatory or other displacement of the table in its guided direction during the scanning movement of the other table. As a result, a practically true straight line of scan is obtained, thereby eliminating the danger of the laser beam incising the work sheet beyond a definite range of allowance.
