1. A medicine packaging apparatus with a medicine packaging sheet roll having a core tube provided with a storage medium,
the medicine packaging apparatus comprising:
a rotation amount information outputting section for an output of rotation amount information as an indication of a rotation amount of a rotating shaft portion to which the medicine packaging sheet roll is attached;
an information reading section for writing information to and reading the written information from the storage medium provided inside the core tube of the medicine packaging sheet roll;
an information generation section for generating, as information writable to the storage medium, based on the rotation amount information output from the rotation amount information outputting section: rotation amount information as of reference sheet-remaining amount timing which is the rotation amount information upon unwinding of a packaging sheet by a predetermined length from the medicine packaging sheet roll attached to the rotating shaft portion at a reference time-point; one or a plural pieces of rotation amount information as of individual current sheet-remaining amount obtaining timings each of which is the rotation amount information upon unwinding of the packaging sheet by the predetermined length from the medicine packaging sheet roll at a packaging sheet in-use time-point after the reference time-point; and an amount of sheet use from the reference time-point through the packaging sheet in-use time-point; and
a remaining sheet amount estimation section for estimation of a current amount of remaining sheet based on the rotation amount information as of reference sheet-remaining amount timing, the rotation amount information as of individual current sheet-remaining amount obtaining timing, the amount of sheet use from the reference time-point through the packaging sheet in-use time-point, and dimensional information of the core tube.
