In a conventional tablet packing device, a tablet discharged from a tablet case is supplied to a medicine packing unit through a common path such as a hopper. Thus, in the conventional tablet packing device, a large number of types of tablets are collected through the common path, so that a problem of cross contamination (the chipped pieces of the tablet of the type different from that of the tablet to be packed are mixed) occurs. The present invention provides a tablet packing device from which common path is eliminated. The present invention is characterized by including a conveyance unit for conveying a tablet case to a case arrangement section so that a tablet can directly be discharged from the tablet case to a tablet packing unit.
