Patent ID: 8523330

Claim:
A recording apparatus, comprising: a liquid droplet discharging head configured to discharge a liquid droplet and including a liquid droplet discharging head circuit board configured to cause said liquid droplet discharging head to discharge said liquid droplet, the liquid droplet discharging head circuit hoard including a hoard substrate, an electricity-heat conversion element configured to generate heat, thereby causing the liquid droplet discharging head to discharge said liquid droplet, a wall provided with a liquid outlet corresponding to the electricity-heat conversion element, through which a liquid droplet is discharged, and a wiring pattern located on the board substrate to supply power and connected to the electricity-heat conversion element, the wiring pattern including a plurality of divided wiring patterns connected directly to the same single electricity-heat conversion element in a state in which the plurality of divided wiring patterns are mounted on the same single electricity-heat conversion element, each divided wiring pattern amongst the plurality of divided wiring patterns electrically connecting the same single electricity-heat conversion element to a same power source, the plurality of divided wiring patterns having been formed by dividing least a part of the wiring pattern in a width direction of the wiring pattern, and the plurality of divided wiring patterns being connected to the same one electricity-heat conversion element corresponding to the liquid outlet, in a state in which the plurality of divided wiring patterns are not simultaneously connected to any other electricity-heat conversion element; and a tank configured to supply a liquid to the liquid droplet discharging head, wherein each of the plurality of divided wiring patterns has a width that provides an allowable electric current per unit wiring width greater than an allowable electric current per unit wiring width of a single wiring pattern having a width equivalent to a combined width of the plurality of divided wiring patterns obtained by adding all of the widths of the plurality of divided wiring patterns to a space provided between two adjacent divided wiring patterns.
