LIQUID JET HEAD AND LIQUID JET DEVICE
Document Type and Number:
Japanese Patent JP2022178379
Kind Code:
A
Abstract:
To eliminate a possibility that temperature increase of a drive circuit is not cooled sufficiently in a recording head including the drive circuit including a switching element.SOLUTION: A liquid jet head includes: a first drive circuit 241A including a switching element which selects a drive element 231 which supplies a drive signal for jetting a liquid from nozzles 218 of multiple drive elements 231; a case 250 defining a first housing part 251A, a space for housing the first drive circuit 241A; and a first gas supply passage 32A which communicates with the first housing part 251A and is used to supply a gas to the first housing part 251A.SELECTED DRAWING: Figure 3
