Abstract:
1. A liquid droplet discharge apparatus comprising: a plurality of head units that discharge liquid droplets from nozzles; a plurality of long members to which the head units are attached, the head units being positioned in a single row along each of the long members such that between two adjacent long members the head units are positioned collaterally; a frame that forms an apparatus body of the liquid droplet discharge apparatus; a portion of each said long member being fixedly attached to said frame and another portion of each said long member being slidably supported by said frame such that said slidably supported portion is slidable with respect to the apparatus body in a longitudinal direction of said long members; at least one fixed support member disposed on said frame and fixedly attaching said long members to said frame; and at least one slide support member disposed on said frame and slidably supporting said long members in the longitudinal direction; wherein said at least one fixed support member rigidly fixes said long members at a longitudinal-direction center of said long members such that said longitudinal-direction center of said long members does not move with respect to the frame, and each end portion of each long member is slidably supported by one said slide support member; each of said at least one slide support member including a groove portion disposed along the longitudinal direction of said long members, and each of said long members including a protruding ridge that engages the groove portion of one slide support member; the protruding ridge having a quadrilateral cross-sectional shape, and the cross-sectional shape of the groove portion corresponding to the cross-sectional shape of the protruding ridge.
