PURPOSE:To correct a defective position by flexibly wiring and connecting wiring leads from electrode styluses disposed in two rows in zigzag state to drive circuit sections provided on base boards at both sides of a discharge printer head. CONSTITUTION:Electrode styluses 1, 1' are buried in the shape in which electrolytic copper is etched in a stripe state, they are arranged in density of 8/mm and connectors are exposed to supports 2, 2'. Extension boards 10, 10' are provided at the supports 2, 2', and base boards 3, 3' of aluminum are temporarily secured through spacers 13, 13'. Extension boards 11, 11', drive ICs 4, 4' and circuit boards 5, 5' are mounted on the substrates 3, 3', respectively; the styluses 1, 1' are connected to the substrates 10, 10' by fine conductors 14, 14'; and the boards 10, 10' are connected to the boards 11, 11' by flexible conductors 12, 12' by a TAB method. Accordingly, even if a defective position exists on the connector or component in manufacture, the defective position can be easily corrected or the defective component can be easily replaced by removing a spacer and opening the circuit sections. |
