摘要

[PROBLEM] TO PROVIDE A DEVICE FOR SELECTING PRINT CHARACTERS OF ENDLESS PRINTING BANDS IN A PRINTER THAT, WHEN RESTRICTING THE ROTATION OF ENDLESS PRINTING BANDS 7 FOR PREVENTING FOULDING OF DISPLAY CHARACTERS 7B, CAN AVOID EXCESSIVE ROTATIONAL FORCE FROM ACTING ON THE ENDLESS PRINTING BANDS 7 THEMSELVES AND ENABLE SELECTIONS OF DESIRED PRINT CHARACTERS 7A IN CASES WHERE, FOR EXAMPLE, THE ENDLESS PRINTING BAND 7 IS FOR FULL-PERIPHERY PRINTING OR HALF-PERIPHERY PRINTING.[MEANS FOR SOLVING THE PROBLEM] FOCUSING ON THE FACT THAT BOTH HALF-PERIPHERY PRINTING CAPABILITY AND FULL-PERIPHERY PRINTING CAPABILITY CAN BE IMPLEMENTED BY PROVIDING REGULATING BLOCKS 6 CAPABLE OF ROTATION AS PRINT PRESSURE BEARING MEMBERS, THE DEVICE IS CHARACTERIZED IN THAT SELECTION OF PRINT CHARACTERS 7A IS RESTRICTED BY ENGAGEMENT OF DRIVE PROJECTIONS 7E OF AN ENDLESS PRINTING BAND 7 AND AN ELASTIC SELECTION 14B OF A MOVABLE STOPPER MEMBER 14 AND THAT, IN THE CASE WHERE NO DRIVE PROJECTION 7E ENGAGES WITH THE ELASTIC SECTION 14B, SELECTION OF PRINT CHARACTER 7A IS MADE POSIBLE AND A REGULATING BLOCK 6 RECEIVES THE PRINT PRESSURE ON THE PRINT CHARACTER 7A.
