PURPOSE:To exactly prevent the blocking of a nozzle by providing a means to regulate the contacting and separating moving direction of each head toward the normal direction of ink nozzle face of corresponding head for every head to a valve device. CONSTITUTION:Slide pins 51 and 52 screwed with a slide plate 50 are thrust through the 8th slit 43h and projected toward the other face 41b of a base plate 41. Bearings 53 and 54 are pieced through each projection, E-rings 55 and 56 are fitted into grooves 51a and 52a near the projected ends of the slide pins 51 and 52, and the slide plate 50 is contacted with one face 41a of the base plate 41 in a slidable manner and can move to the direction of the 8th slit 43h. An L-shaped bracket 57 is fixed on the opposite side of the base plate 41 to the slide plate 50. The 8th pad 42h is a rubber molding having a head with a flat face 44 and a basal portion 60 with an annular groove 59, which is fixed by fitting the annular groove 59 into the bottom hole 57a of the bracket. |
