PURPOSE:To improve transfer efficiency by floating slightly an article to be transferred on an upper face plate with air injected from a plurality of vent holes to transfer the article by a magnetic combination with a magnetic body on a chain turning along a predetermined path. CONSTITUTION:This transfer apparatus preferable for an auto-sample changer attached to an automatic dripping unit has a non-magnetic material made upper surface plate 12 formed with a plurality of vent holes 13 along a transfer path of a container 11. Each container 11 is formed in the form of a tray for receiving a beaker, and in the lower surface with a recess 17 for intensifying the floating effect due to injected air. A magnet 18 is embedded in the center of the recess 17. On the underside of the upper surface plate 12 is disposed a bottom plate 14 slightly spaced therefrom and a gas chamber 16 to which pressurized air is forcibly sent is defined between both plates 12, 14. Also, a chain 26 circulating along a container transferring path is disposed beneath the bottom plate 14 to constitute a container transferring means by mounting magnets 28 on the chain 26 in a predetermined pitch. |
