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.

A liquid transfer device, comprising:
- a reserver that stores 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 in which a depressing section is fixed to the rotation axis for depressing the tubes with a helical-structured convex portion each provided thereto, wherein
- when the rotation axis rotates, the liquid starts to flow by the depressing section sequentially depressing the tubes in a direction from the reserver toward a flow-out side of the liquid.
A liquid transfer device, comprising:
- a reserver that stores therein a liquid;
- a first tube and a second tube linked to the reserver in different direction;
- a rotation axis that is retained to be able to rotate;
- and
- a depressing member including a first depressing section that is fixed to the rotation axis and depresses the first tube using a helical-structured convex portion provided thereto, and a second depressing section that is fixed to the rotation axis and depresses the second tube using a helical-structured convex portion provided thereto with a helical direction opposite to the convex portion depressing the first tube, wherein
- when the rotation axis rotates, the liquid starts to flow in two different directions by the first depressing section and the second depressing sections sequentially depressing the first tube and the second tube in a direction from the reserver toward a flow-out side of the liquid.
