Abstract:
A fuse element can be reliably blown and data that corresponds to whether or not the fuse element has been blown can be stored with high reliability. A resistor element is provided in a circuit through which an electric current flows to blow the fuse element in the ink jet printing head. The resistor element adjusts the electric current so that, in the process of blowing the fuse element, the current continues to flow for a predetermined duration even after a maximum current has passed through the fuse element. The predetermined duration is longer than a period from a time point when the electric current rises to a time point when the electric current reaches the maximum current.
