Abstract

Medicine packaging apparatuses and methods for accurately determining a remaining sheet amount of a medicine packaging sheet are described. The apparatus includes: a roll support section to which a core tube of a medicine packaging sheet roll is attached; a sensor disposed in the roll support section for outputting a count value according to a rotation amount; a wireless reader-writer unit for writing information to a core tube IC tag and reading said information; an information generation section for generating information to be written to the core tube IC tag; a remaining sheet amount estimation section for estimating a current amount of remaining sheet based on the information and dimensional information of the core tube; and a controller which selectively performs an operation if a reference time-point count value is not yet written to the core tube IC tag and another operation if the count value is already written thereto.

First claim

What is claimed is:

1. A medicine packaging apparatus for packaging medicine and making a print by using an ink ribbon roll and a medicine packaging sheet roll, the apparatus comprising:
a gap making section for making a first state in which a printing head and a backup section opposed thereto are spaced from each other by a first distance, and a second state in which they are spaced from each other by a second distance which is longer than the first distance;
a winding controller for controlling a winding of the ink ribbon to remove a slack in an ink ribbon in the ink ribbon roll in the second state; and
a controller for making the second state and performing a control of the winding of the ink ribbon upon determination that there is a possibility for the ink ribbon roll to be replaced.

2. The medicine packaging apparatus according to claim 1 , comprising a printing and packaging unit including a printing section which makes use of the ink ribbon roll and the medicine packaging sheet roll, and a packaging section which makes a medicine packaging operation; the printing and packaging unit being movable out of a main body of the apparatus toward a front side, wherein the controller makes the second state and performs the control of the winding of the ink ribbon upon detection that the printing and packaging unit is moved from within the apparatus main body toward the front side and determination that there is a possibility for the medicine packaging sheet roll to be replaced.

3. The medicine packaging apparatus according to claim 1 or claim 2 , further comprising a detection section for detection of an end of the ink ribbon roll, wherein the controller determines that there is a possibility for the ink ribbon roll to be replaced upon detection of the end of the ribbon roll via the detection section.
