Provided are apparatus and method for distributedly storing an object in a plurality of data centers included in a cloud storage system. The method comprises: grouping together the voicing parameters, pitch, gains, LSF coefficients over N consecutive frames to form a superframe, and performing a vector quantization of the voicing information in the course of each superframe by formulating a classification using the information on the chaining in terms of voicing existing over 2 consecutive elementary frames. In addition, the parts present from the sectioning portion to the rear end of the collector are laid out so that ink will be able to spread and wet the surfaces of the parts other than the ink tank.
