Abstract:
1. A device for detecting a target substance in a sample, the device comprising: a dispensing arm for dispensing a sample using a pipette tip; a pipette tip supply device for supplying the pipette to the dispensing arm; a preparing section configured to prepare an analyzing sample by using a reagent and the sample dispensed by the dispensing arm attaching the pipette tip; and a detecting section for detecting a target substance in the analyzing sample prepared by the preparing section; wherein the supply device comprises: a storage section configured to store a plurality of pipette tips, each of the pipette tips having a distal end, body part and an attachment part which is attached to the dispensing arm; a sort section including a push-up plate to push up a pipette tip supplied from the storage section and a wall section fixedly arranged adjacent to the push-up plate and at a downstream side of the push-up plate, wherein the push-up plate is configured to send the pipette tips one-by-one over the wall section, wherein the push-up plate has a slanted surface part that is defined by a plane in a width direction and inclined in a thickness direction and is configured to vertically move along the wall section between a receiving position for receiving the supplied pipette tip and a sending position for sending the supplied pipette tip over the wall section, and an upper end portion of the wall section is inclined in a thickness direction of the wall section and has a slanted surface part inclined in a width direction of the wall section; a movement section configured to transport the sent pipette tip to a pipette tip receiving position; a conveying rack having a hole for holding the transported pipette tip; and a slide rail configured to move the conveying rack and arranged between the pipette tip receiving position and an attachment position for attaching the pipette tip to the dispensing arm, wherein the conveying rack is movable along the slide rail between the pipette tip receiving position and the attachment position; wherein the dispensing arm is configured to attach the pipette tip conveyed by the conveying rack at the attachment position.
