Abstract: A liquid discharge apparatus includes a head configured and arranged to discharge a liquid including a sedimentary substance, and a liquid supply path configured and arranged to supply the liquid from a liquid tank where the liquid is retained to the head. The liquid supply path has a region with differences in elevation of a predetermined length or more in a vertical direction. The liquid supply path has at least one convex section formed by folding at each of one side and another side in a direction which intersects the vertical direction in the region.
Abstract translation: 液体排出装置包括头部，头部被构造和布置成排出包括沉积物质的液体，以及液体供给路径，该液体供给路径被构造和布置成将液体从液体保留在液体罐中的液体供应到头部。 液体供给路径具有在垂直方向上具有预定长度或更大的仰角差异的区域。 液体供给路径具有至少一个凸部，该凸部通过在该区域中的与垂直方向相交的方向上的一侧和另一侧的每一侧折叠而形成。
