Abstract: A receiving device is provided, comprising a chamber, a first cover unit and a second cover unit. The chamber has an opening and a plurality of receiving spaces. The first cover unit comprises a first cover element. The second cover unit comprises a second cover element, wherein the opening is closed when the first cover element and the second cover element contact each other, and the opening is opened when the first cover element and the second cover element separate from each other.

Abstract: A receiving device is provided, comprising a chamber, a plurality of spacers, a plurality of positioners and a spacer moving module. The spacers are disposed in the chamber, wherein the spacers define a plurality of receiving spaces. The positioners are disposed in the chamber, wherein the spacers are detachably disposed on the positioners. The spacer moving module is disposed in the chamber, wherein the spacer moving module moves the spacers relative to the positioners to change sizes of the receiving spaces.
