A medicine packaging apparatus, a medicine packaging sheet remaining amount determination method, and a medicine packaging sheet roll make it possible to accurately determine a remaining sheet amount of a medicine packaging sheet. The apparatus includes: a roll support section (2) to which a core tube (201) of a medicine packaging sheet roll (200) is attached; a sensor (24a) disposed in the roll support section (2) for an output of a count value in accordance with a rotation amount; a wireless reader-writer (26) which has antennas (25) in the roll support section (2) and writes information to a core tube IC tag (202) disposed in the core tube (201) and reads the written information, using the antennas (25); an information generation section (57a) for generation of information to be written to the core tube IC tag (202); a remaining sheet amount estimation section (57) for estimation of a current amount of remaining sheet based on the information and dimensional information of the core tube (201); and a controller (5) which selectively performs an operation for a case where a reference time-point count value is not yet written to the core tube IC tag (202) and an operation for a case where the count value is already written thereto. |
