Patent ID: 7075674

Claim:
An image recording apparatus comprising: a plurality of groups of driven elements which are driven for printing on a medium; a driving section connected to the driven elements; a first memory for storing a plurality of correction values for correcting for variations in the driven elements, each correction value corresponding to a respective one of the driven elements; a print controller for receiving an input data signal and controlling the driving section and the first memory, the print controller generating a clock signal the print controller including a second memory; and a connection arrangement for connecting the print controller to the driving section, the connection arrangement including a clock signal line, a data line, and a plurality of strobe signal lines, the strobe signal lines connecting the print controller to the first memory in addition to the driving section, wherein the print controller reads the connection values out of the first memory using the strobe signal lines, the read-out correction values being stored in the second memory and then being transmitted to the driving section over the data line in synchronism with the clock signal, wherein the print controller generates print data from the input data and transfers the print data to the driving section over the data line in synchronism with the clock signal, the print data being transferred to the driving section after the correction values have been transferred to the driving section, and wherein the print controller generates strobe signals that are conveyed to the driving section via the strobe signal lines and that cause the driving section to drive the groups of driven elements in accordance with the print data.
