Abstract
A group of serial-in, parallel-out shift registers has a separate output positionally corresponding to each of the pins of a multipin recording head which is maintained in marking relationship with a moving electrosensitive record sheet. Each of the shift register outputs is connected to the corresponding one of the pins by way of a pin-driving transistor which energizes its pin when a logic zero appears in the corresponding shift register output. A binary number to pin position decoder receives a binary number representing an analog input signal and repeatedly serially shifts corresponding binary bit trains into the shift registers. Due to the time required for an energized pin to mark the sheet, logic zero bits shifted into the registers cause pins to mark the sheet only after those bits are in their final loaded positions in the shift registers at the completion of each shifting operation.
