Device for the exact positioning of a printing head with respect to a recording substrate

摘要

A recording substrate (21) is brought into a predetermined position on a recording substrate receiver (10). One edge of the recording substrate (21) bears on a recording substrate stop (18) provided laterally on the recording substrate receiver (10). A transmitting or receiving means (KS), which can be covered by the recording substrate (21), extends transversely to the recording substrate stop (18) in or on the recording substrate receiver (10). A receiving or transmitting means (KE) is provided on the printing head (7). In the region of the extension of the transmitting or receiving means (KS), at a defined distance from the recording substrate stop (18), a screening surface (30) is arranged on the recording substrate receiver (10). During the movement of the printing head (7) along the transmitting or receiving means (KS), the location of the screening surface (30) and the location of the recording substrate edge facing away from the recording substrate stop (18) are detected. <IMAGE>
