Medicine packaging device, medicine packaging paper remaining amount judging method and medicine packaging paper roll

摘要

Provided are a medicine packaging device, a medicine packaging paper remaining amount judgment method, and a medicine packaging paper roll that make it possible to accurately judge the remaining amount of medicine packaging paper. A roll support unit 2 to which the core tube 201 of the medicine-wrapping paper roll 200 is mounted, a sensor 24a provided in the roll support unit 2 that outputs a count value corresponding to the rotation amount, and an antenna connected to the roll support unit 2 25, and information is written to the core tube IC tag 202 provided in the core tube 201 using the antenna 25, and the wireless reader / writer 26 that reads the written information, and information to be written to the core tube IC tag 202 Based on the information generation unit 57a for generating the remaining amount of paper and the dimensional information of the core tube 201, the remaining paper amount estimation unit 57 for estimating the current remaining amount of paper, and the core tube IC tag 202 with a reference time point count. And a controller 5 that selectively performs processing when a value has not yet been written and processing when a value has already been written.
