A wiping-type sample sampling and feeding device comprising: a thermally desorbing portion configured to thermally desorb a sample fed into the thermally desorbing portion; a wiping-type sampling portion including a first wheel and a second wheel that are rotatable about their respective axes, and a wiping conveyor belt that is tensioned by the first and second wheels and travels between the first and second wheels along a first direction by means of rotation of the first and second wheels , wherein the wiping conveyor belt travels through the thermally desorbing portion to enable the thermally desorbing portion to desorb the sample on the wiping conveyor belt as the wiping conveyor belt enters the thermally desorbing portion; 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 is able to contact and wipe a surface of the wiping conveyor belt during conveyance of the card or certificate , wherein the second direction is substantially perpendicular to the first direction, wherein the wiping-type sampling portion and the thermally desorbing portion are both arranged within a same working chamber located above the card carrying belt , and the working chamber is provided with a wiping opening oriented toward an upper surface of the card carrying belt so that the wiping conveyor belt is able to contact a surface of the card or certificate placed on the card carrying belt so as to wipe the surface of the card or certificate ; and the working chamber includes a wiping opening seal configured around the wiping opening to contact the card carrying belt when the wiping opening gets close to the card carrying belt so as to prevent external substances from entering the wiping opening. a thermally desorbing portion configured to thermally desorb a sample fed into the thermally desorbing portion; a wiping-type sampling portion including a first wheel and a second wheel that are rotatable about their respective axes, and a wiping conveyor belt that is tensioned by the first and second wheels and travels between the first and second wheels along a first direction by means of rotation of the first and second wheels , wherein the wiping conveyor belt travels through the thermally desorbing portion to enable the thermally desorbing portion to desorb the sample on the wiping conveyor belt as the wiping conveyor belt enters the thermally desorbing portion; 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 is able to contact and wipe a surface of the wiping conveyor belt during conveyance of the card or certificate , wherein the second direction is substantially perpendicular to the first direction, wherein the wiping-type sampling portion and the thermally desorbing portion are both arranged within a same working chamber located above the card carrying belt , and the working chamber is provided with a wiping opening oriented toward an upper surface of the card carrying belt so that the wiping conveyor belt is able to contact a surface of the card or certificate placed on the card carrying belt so as to wipe the surface of the card or certificate ; and the working chamber includes a wiping opening seal configured around the wiping opening to contact the card carrying belt when the wiping opening gets close to the card carrying belt so as to prevent external substances from entering the wiping opening. <EOS>
