摘要： An object of this invention is to provide a driving circuit layout which suppresses an increase in the area of a head substrate in an inkjet printhead adopting a driving method for supplying a predetermined current to a heater. To achieve this object, a plurality of printing elements and a plurality of switching elements which are very large in number are arrayed in the longitudinal direction of a head substrate. A plurality of terminals which receive a driving signal and a control signal that are used to drive the plurality of printing elements are arranged at the end of the board in the longitudinal direction of the board at positions opposite to the array of the plurality of printing elements. A constant electric current source for supplying a predetermined electric current is interposed between these two regions.

摘要： This invention provides a printing head which can prevent an increase in the number of block enable signal lines, and can prevent changes in printing ink density caused by interference due to the relative pressures of nozzles generated in ink discharge, and an image printing apparatus using the printing head. For this purpose, an increase in the number of input signal lines along with an increase in the number of blocks is prevented using a block clock signal or the like instead of a block enable signal as an input signal to the printing head. Three ring counters generate signals having different nozzle driving orders. These signals are selectively used by a ring counter selection signal. Ink is not always discharged from the nozzles in the same output order. This can prevent changes in ink density caused by pressure interference.
