素子基板、記録ヘッド、及び記録装置
Document Type and Number:
Japanese Patent JP7266424
Kind Code:
B2
Abstract:
To provide an element substrate that is reduced in substrate area to lower manufacturing costs, and also can prevent wrong detection when a plurality of temperature detecting elements are selected, a recording head using the element substrate, and a recording device using the recording head.SOLUTION: An element substrate comprises a plurality of electrothermal conversion elements, a plurality of temperature detecting elements corresponding to the plurality of electrothermal conversion elements, and a common selection circuit which selectively drives the plurality of electrothermal conversion elements and the plurality of temperature detecting elements. The element substrate further comprises a determination circuit which determines whether the number of the selected electrothermal conversion elements is two or larger, and a control circuit which performs control to output an output signal from the selected temperature detecting element to the outside according to a result of the determination by the determination circuit.SELECTED DRAWING: Figure 7
