According to the present invention, it is possible to manufacture a blood-collecting apparatus in which a plurality of lancets are coupled to a drum and formed to be extracted from and introduced into the drum, thereby achieving automatic use of the lancets without the need for replacing the lancets one by one, and when the lancets are used while being coupled to a multi-lancet driving apparatus, a cartridge having the plurality of lancets accommodated therein can be repeatedly rotated through forward and backward motion of a cam plate connected to an index lever, thereby easily achieving an operating mechanism for sequentially using the lancets. In addition, according to the present invention, as the cam plate which may be brought close to a base plate slides in the forward and backward directions along the Y axis, lancet movement is made to extract/introduce the lancets from/into the cartridge so that the lancets can be automatically used and the thickness of the entire apparatus can be made small, thereby manufacturing a compact blood-colleting apparatus. Moreover, the cartridge having the plurality of lancets accommodated therein can be repeatedly rotated through the forward and backward motion of the cam plate connected to the index lever, thereby easily achieving the operating mechanism for sequentially using the lancets, and a necessary lancet is used while the cartridge having two or more lancets accommodated therein rotates in an automatic manner, thereby solving user inconvenience of directly replacing the lancets.Selon la présente invention, il est possible de fabriquer un appareil de collecte de sang dans lequel une pluralité de lancettes sont accouplées à un cylindre et formées de manière à être extraites du cylindre et introduites dans ce dernier, ce qui permet de procéder à une utilisation automatique des lancettes sans avoir besoin de remplacer les lancettes individuellement, et lorsque les lancettes sont utilisées en étant accouplées à un appareil d
