Liquid transfer device and suction unit

Abstract

A liquid transfer device that includes: a plurality of reservers that each store therein a liquid; a plurality of elastic tubes that are linked to the reservers and retained by a tube guide; a rotation axis that is retained to be able to rotate; and a tube depressing member whose depressing section is fixed to the rotation axis for depressing the tubes with a helical-structured convex portion provided thereto. In the liquid transfer device, when the rotation axis rotates, the liquid starts to flow by the depressing section sequentially depressing the tubes in a direction from the reservers toward a flow-out side of the liquid.
