A selective transfer device, comprising: a transfer part transferring a transfer object; a transfer inlet and a serial inlet supplying the transfer object to the transfer part; an outlet ejecting the supplied transfer object; and an air pressure supplier supplying air to the transfer part, wherein the transfer part 100 comprises a transfer body of plate shape having a predetermined thickness; a first moving path, a second moving path and an ejecting path formed on a thickness surface of the transfer body along a direction of the transfer object moving; a first shutter and a second shutter formed in the second moving path and the ejecting path to regulate inflow of air and moving of the transfer object, wherein the first moving path and the second moving path is disposed apart from each other, gradually closed along the direction of the transfer object moving, and joined each other to form the ejecting path, and wherein the transfer inlet is in communication with the first moving path, the serial inlet is communicate with the second moving path, the transfer object is selectively inserted in the first moving path and the second moving path and ejected through the ejecting path to the outside, wherein the air pressure supplier comprises a first air pressure supplier injecting air into the first moving path, a second air pressure supplier injecting air into the second moving path, and a third air pressure supplier injecting air into the ejecting path, wherein the second air pressure supplier is installed at a downstream side in the direction of the transfer object & moving from the first shutter which is disposed in the second moving path, wherein the third air pressure supplier is installed at a side the downstream side in the direction of the transfer object moving from the second shutter which is disposed in the ejecting path, wherein a third air injecting hole and a second air injecting hole is formed at bottom surface of the transfer body to be respectively connected with the third air pressure supplier and the second air pressure supplier and respectively communicated with the ejecting path and the second moving path, wherein the second blocking plate of the second shutter is obliquely disposed in the moving direction of the transfer object on the third air injecting hole to be turned by air injected from the third air injecting hole such that the ejecting path is opened or closed, and wherein the first blocking plate of the first shutter is obliquely disposed in the moving direction of the transfer object on the second air injecting hole to be turned by air injected from the second air injecting hole such that the second moving path is opened or closed.. a transfer part transferring a transfer object;
