Valuable file identification device

摘要

A valuable file identification device, comprising a housing (1); a hollow transparent drum (21); an annular clamping belt (41) supported by at least two tension rollers (301-312) and pressing against the transparent drum (21), the outer surface of the annular clamping belt (41) and the outer surface of the transparent drum (21) forming a clamping and conveying channel for the valuable file, and the length of the clamping and conveying channel being greater than that of the valuable file in the conveying direction; at least one information acquisition device (51), the information acquisition element of the information acquisition device (51) being adjacent to the inner surface of the transparent drum (21), facing at least a part of the outer surface of the annular clamping belt (41), and being fixed relative to the side wall (11, 12) of the housing (1); and a power-driven device respectively driving the transparent drum (21) and the annular clamping belt (41) to move synchronously in opposite directions.
