Abstract
In order to efficiently detach and collect an IC tag (1) from a paper sheet (2) to which the IC tag (1) is attached, the IC tag (1) is detached from the paper sheet (2) by applying external force to the adhesive surface between the paper sheet (2) and the IC tag (1) (detachment step). Next, the detached IC tag (1) is fractionated from other substances (fractionation step).

1-20. (canceled)
A method of detaching and collecting an IC tag from a paper sheet to which said IC tag is attached, comprising:
- a detachment step of detaching said IC tag from said paper sheet by applying external force to an adhesive surface between said paper sheet and said IC tag;
- and
- a fractionation step of fractionating the detached IC tag from other substances.
A system for detaching and collecting an IC tag from a paper sheet to which said IC tag is attached, comprising:
- a unit for swelling said paper sheet by causing said paper sheet to hold a swelling liquid in which paper and/or an adhesive is soluble;
- a detacher for detaching said IC tag from said paper sheet by applying external force to an adhesive surface between the swollen paper sheet and said IC tag;
- and
- a fractionator for fractionating the detached IC tag from other substances.
An apparatus for detaching and collecting an IC tag from a paper sheet to which said IC tag is attached, comprising:
- a detaching container for storing a liquid;
- a solid type screen, which is provided within said detaching container and functions as a filter, for holding said paper sheet to which said IC tag is attached;
- an agitator for generating a flow of said liquid within said detaching container by agitating said liquid;
- and
- discharge ports, formed in side and/or bottom surfaces of said detaching container, for discharging paper components, passed through said solid type screen, of the paper components of said paper sheet fragmented within said solid type screen by said flow generated by said agitator.
