The present invention is directed to formulations premix utilized in pellet structured frozen dessert type product. The blade is movable from an inoperative position in which the blade root is spaced from a print sheet contacting an imaging member by a first distance. For this purpose, inner diameters of a plurality of ink discharge tubes running from a plurality of cap units, which cap a plurality of print head units having different numbers of ejection portions, to the common pump are differentiated. In this way, the mobile terminal apparatus can use sufficient resources to execute a multicast data download communication mode, so that it can receive the broadcasted contents without fail. The physician or user is thereby assured that the expandable structure meets established performance and sterility specifications, and will have the desired configuration when expanded for use.
