Multi-needle head, method of aligning end portion of multi-needle head, and alignment device used therein

Abstract

Proposed is a multi-needle head. The multi-needle head includes at least one adapter mounted with a needle in which liquid is discharged therethrough, and includes a holder in which the adapter is fixed. An O-ring having an outer diameter thereof larger than a width of a body of the adapter is coupled to the body of the adapter, a fixing hole into which the body of the adapter is inserted is formed in the holder, and an O-ring fixing portion having an inner diameter thereof larger than an inner diameter of the fixing hole is formed in the middle of the fixing hole such that the O-ring is positioned at the O-ring fixing portion. A vertical width of the O-ring fixing portion is larger than a vertical width of the O-ring, thereby allowing a height of the adapter that is fixed to the holder to be adjusted.

Dependencies are inferred from the claim text.
