ELEMENT SUBSTRATE CAPABLE OF CONTROLLING THE INFLUENCE ON A STRUCTURE, A FUNCTION, AND THE PERFORMANCE OF A SENSING ELEMENT, A PRINT HEAD, AND A PRINTING DEVICE

摘要

PURPOSE: A element substrate, a print head, and a printing device are provided to omit one of reading wires for two terminals of a sensing element as the terminals of the sensing element, which is commonly connected to constant-current wires, is connected to a first common wire by using wires of the adjacent sensing device.;CONSTITUTION: An element substrate comprises a first resistance element(702), a second resistance element(706), and sensing members(704,705,713). The first and second resistance elements respectively include a first terminal and a second terminal and are arranged in a preset direction. The first terminals of the first and second resistance elements are selectively connected to a first line for supplying current, and the second terminals of the first and second resistance elements are commonly connected to the second line for supplying current. While power is supplied to the first resistance element and the power is not supplied to the second resistance element, the sensing member detects voltages of the first terminals of the first and second resistance elements.;COPYRIGHT KIPO 2013;[Reference numerals] (714) Temperature sensing element selection circuit; (717) Printing element selection circuit;
