RESEQUENCING LINE STORE DEVICE

摘要

An image recording apparatus (10) is provided with relatively inexpensive data line resequencing circuitry (125) for formatting image signals to a print head (20). The circuitry (125) includes resequencing line store devices (127, 128) each connectable to a data link and a control link for resequencing at least one first line of sequentially ordered data bits carried by the data link according to control signals carried by the control link. The resequencing line store device includes a plurality of interconnected memory cells (150) operable for storage and selectable transfer of the data bits in response to the control singals, whereby the plurality of cells are arranged in a plurality of cell groups (152, 154) and a plurality of cell subgroups (160, 162, 170, 172) corresponding respectively to first and second partitions of the bits. The bits may be shifted into the plurality of groups in sequential order and shifted from the plurality of cell subgroups in a non-sequential order corresponding to the first and second partitions. The contemplated apparatus (100) is preferred for use in an electrostatographic reproduction apparatus (10) wherein rasterized image signals are fed to the resequencing circuit (125) for resequencing the image data on a line-by-line basis in a subsequent transfer of the data to a recording means (20), such as a print head, wherein a plurality of recording elements (31) are arranged in a line configuration. Intermediate register means (41) outputs the image signals in parallel in each of several shift register assemblages. Driving means (40) actuate the elements (31) for recording on a line-by-line basis.
