A packaging section of a tablet packaging device includes: a placement base of a tray; a drawer storing the placement bas; a carrier provided with compartments corresponding to the storage concave portions of the tray; a drive device of the carrier; a shutter opening/closing; a bottom of the carrier; and an opening/closing device of the shutter. The drive device performs a step of defining a tablet discharge position on the tray as an original position and returning to the original position through a tablet reception start position and a tablet reception end position which are set below a discharge opening. A step of sequentially moving each compartment of the carrier below the discharge opening from the tablet reception start position to the tablet reception end position during the step to receive one tray of tablets is performed. When the carrier returns to the discharge position, the shutter is opened.
