Title:
AUTOMATIC ANALYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/244427
Kind Code:
A1
Abstract:
When a dispensation tip is not attached properly or when smudges or residue on the leading end of a dispensation tip adheres to a disposal path, dispensation tips cannot be disposed of due to being adhered to the disposal path, or fallen dispensation tips pile up in a bamboo shoot manner, causing the dispensation tips to spill out of the disposal box. According to the present invention, attachment of a tip is stabilized by adding a countersink 201 to the backside of a dispensation tip mounding position 132 of an installation table of specimen dispensation tips and by reducing the amount of contact with respect to the tip lateral surface during pulling-up from the installation table. In addition, sticking of a specimen to the disposal path is suppressed by adding a member for controlling the attitude of a tip when falling to a disposal position so as to cause the tip to drop vertically. Further, when raising a dispensation probe during release of a dispensation tip, the attitude of the tip during release is stabilized by raising the tip until the upper end thereof touches a base, temporarily halting the motion of the tip, and then raising the tip again. Still further, a plurality of positions for releasing tips are provided, and the timing for disposal is changed from one position to another.
