Abstract:
The present invention discloses a wiping-type sample sampling and feeding device, a card reading apparatus, and a gate machine apparatus. The wiping-type sample sampling and feeding device comprises a thermally desorbing portion for analyzing a substance; a wiping-type sampling portion for wiping the substance on a card or certificate and includes a first wheel, a second wheel and a wiping conveyor belt that travels between the first and second wheels along a first direction; and a card/certificate conveyor portion including a card carrying belt configured to convey a card or certificate along a second direction so that the card or certificate can contact with the wiping conveyor belt during conveyance of the card or certificate, thereby the wiping conveyor belt wipes a surface of the card or certificate, wherein the second direction is substantially perpendicular to the first direction.
