Ink jet recording head and ink jet recording device

Abstract

The present invention provides an ink jet recording head and an ink jet recording device respectively simply and precisely formed, the ink jet recording head and the ink jet recording device are characterized as follows. For the ink jet recording head, an elastic member is inserted between a head chip and an ink supply member and is pressed upon them by a bolt. As a result, a convex portion of the ink supply member comes into contact with a holding member to which the head chip is fastened and the distance between the head chip and the ink supply member is fixed. Therefore, the compressed amount of the elastic member is fixed, the sealing performance of a connection of an ink supply port of the head chip and a supply passage of the ink supply member is secured and it becomes possible to prevent excessive force from acting upon the head chip and damaging the head chip. Therefore, the ink jet recording head can be provided by a precise and simple method.
