Print element control unit for representing slanted text (italics), especially in data terminals and in matrix printers

摘要

have such a digital microprocessor for representing italics (italics), particularly in workstations and on matrix printers, the column-wise arranged pressure elements (D1 to D12), connected downstream via a character generator and / or microprocessor and a driver circuit (46) for the individual printing elements (D1 to D12) connected upstream of the delay means for triggering of the pressure elements (D1 to D12), wherein the delay means associated from each printing element, different each time activatable shift registers (SR1 to SR12) which is proposed for bidirectional imaging or printing of the characters, namely such that to a data bus (B.1) is connected, a mode register (3) via a first, the shift registers (SR1 to SR12) upstream data selection logic (10) and the shift registers (SR1 to SR12) downstream, second data selection logic ( 11) the shift registers (SR1 to SR12) for switches the writing of vertical character inactive or active switches for writing oblique characters, wherein in the active switching state, the assignment of the shift registers (SR1 to SR12) to the printing element terminals (N1 to N12) of an ascending sequence (N1 to N12) in a descending order (N12 - N1) is changeable.
