Zusammenfassung:	A MECHANISM FOR PREVENTING FOULING OF PRINTER DISPLAY CHARACTERS IN A PRINTER (30) HAVING A PLURALITY OF PARALLELY DISPOSED DISPLAY WHEELS (38) AND A PLURALITY OF DISPLAY SPACERS (42) WITH STATIONARY ENGAGEMENT PROJECTION (43) DISPOSED BETWEEN ADJACENT ONES OF THE DISPLAY WHEELS (38). THE MECHANISM COMPRISES AN ANNULAR GROOVE (40) FORMED IN ONE SIDE SURFACE OF EACH DISPLAY WHEEL (38) FOR RECEIVING THE ENGAGEMENT PROJECTION (43) OF THE ASSOCIATED DISPLAY SPANCER (42) THEREIN, A VERTICAL SLIT (41) FORMED OVER A PRESCRIBED ANGLE IN THE FACE OF EACH DISPLAY WHEEL (38) TO COMMUNICATE WITH THE ANNULAR GROOVE (40) THEREOF, AND A MOVABLE STOP (44) FITTED IN THE ANNULAR GROOVE (40) AND THE VERTICAL SLIT (41) OF EACH DISPLAY WHEEL (380 TO BE SLIDABLE OVER THE RAGE OF THE VERTICAL OF THE VERTICAL SLIT (41). THE MOVEMENT OF ENDLESS TYPE BANDS (50) BY ROTATION OF THE DISPLAY WHEELS (38) FOR CHARACTER SELECTION IS REGULATED BY THE MOVABLE STOPPER (44) BEING PUSHED BY THE ASSOCIATED ENGAGEMENT PROJECTION (43) TO ABUT ON ONE OR THE OTHER END OF THE VERTICAL SLIT (41). THIS REGULATION ALLOWS INK TO BE APPLIED TO PRINT CHARACTERS OF THE TYPE BANDS (50) BUT PREVENTS IT FROM BEING APPLIED TO DISPLAY CHARACTERS (52) THEREOF.(FIG. 1)
