Title:
LIQUID JETTING HEAD AND LIQUID JETTING DEVICE
Document Type and Number:
Japanese Patent JP2018024261
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain a small liquid jetting head which achieves reduction of a cost and is excellent in absorption efficiency of pressure variation of a pressure generating chamber or the like.SOLUTION: Since a reservoir part 32 is formed also on a through-hole 33, an area of a sealing film 41 of a compliance substrate 40 is kept large, consequently, absorption efficiency of pressure variation is improved. A part of the reservoir part 32 is formed also on a through-hole 33 in a direction where a flow path forming substrate 10, a protective substrate 30, and a reservoir forming substrate 35 are piled up. Consequently, a small inkjet type recording head 1 can be obtained, which suppresses increase in a cost in comparison with a case where the reservoir part 32 is formed by broadening the substrates while keeping away from the through-hole 33.SELECTED DRAWING: Figure 7
