Title:
LIQUID JETTING HEAD, LIQUID JETTING RECORDING APPARATUS, AND METHOD FOR FILLING LIQUID JETTING HEAD WITH LIQUID
Document Type and Number:
WIPO Patent Application WO/2010/070975
Kind Code:
A1
Abstract:
The space factor of a liquid jetting head is improved, and the degree of freedom in designing a liquid jetting recording apparatus is improved. Performance of recovering a surplus liquid is improved with a simple configuration, contamination due to the surplus liquid is eliminated, the liquid jetting recording apparatus is initially filled, and liquid jetting after the liquid filling is stabilized.
The liquid jetting head is provided with: a wall section (24), which surrounds the periphery of a jetting port row and protrudes in the same direction as the opening direction of a jetting port; an opening/closing mechanism (60), which has a cover member (62) that can open/close an opening section (24n) formed by the wall section (24), configures a closed space between the wall section (24) and the jetting body (23) in the closed state, and exposes the jetting port to the outside in the opened state; an absorber (40), which is provided on a rear surface (62b) of the cover member (62) and absorbs the liquid spilled out from the jetting port; a suction channel (15), which has a suction port (15a) opened to the closed space and is connected to an external suction apparatus (8); and a section (33) opened to atmosphere, which can perform switching between opening and blocking of the closed space to and from the outside.
