Abstract: A hard capsule for pharmaceutical drugs comprises a water-soluble cellulose derivative as a capsule base, a gelatinizing agent and an auxiliary for gelation. The hard capsule is prepared by preparing an aqueous solution of a capsule base containing a water-soluble cellulose derivative, a gelatinizing agent and an auxiliary for gelation, immersing a capsule molding pin in the aqueous solution of the capsule base, subsequently drawing out the molding pin from the aqueous solution of the capsule base, subjecting the aqueous solution of the capsule base attached to the outer surface of the molding pin to gelate at room temperature, and forming a capsule film on the outer surface of the molding pin.
Abstract: A printer for printing predetermined patterns of letters, figures, marks and the like on surfaces of solid articles such as tablets or capsule articles which includes a horizontal carrier for carrying the regularly arranged solid articles in a horizontal direction, an ink pattern transfer device for transferring the patterns on the surfaces of the solid articles, a print quality judging device for judging the quality of the printed ink patterns and an inferior article remover for automatically removing articles of inferior print quality from the manufacturing process.
