Abstract
A storage circuit for editing printing data for metal paper printers in which the printer has a plurality of spaced electrodes arranged on a slope. The data in binary form are to be recorded in a matrix of rows and columns and are supplied in columnar fashion to a register from which they are grouped and read into a storage with corresponding bit positions of the groups being stored concurrently during a write operation. An address control appropriately places the stored bits to accommodate the spacing between electrodes for the respective data bits.
Claims10
A digital storage circuit for editing binary data bits for a print head moving along a print line on a recording medium in which said print head records said data in a matrix of rows and columns of data bits and includes a plurality of electrodes arranged on a slope and spaced from each other along the print line a predetermined number of data bit positions comprising;
- storage means for each said electrode for storing therein a row of data for the respective electrode, said storage means being organized in groups;
- register means having a plurality of stages for receiving a column of said data bits with said plurality of stages being grouped to correspond to said groups of storage means and each said stage temporarily holding data for a respective one of said storage means;
- and
- address means for transferring to each of said row storage means the data received in said respective one of said register stages with the data in corresponding register stages within each group being stored simultaneously and at an address in a said respective storage means equivalent to the number of data positions separating each said electrode from a first electrode.
