  • Patent number: 7194746
    Abstract: A tray drive mechanism has a simple structure, and yet both an optical disc clamping operation and a tray opening and closing operation can be driven by one feed motor. The tray drive mechanism comprises: a feed gear and a tray drive gear that are rotated by a feed motor; a rack member to mesh with the feed gear so as to be driven in direction to inner circumference of the optical disc; a plate trigger driven by the rack member so as to slide; and a cam slider to slide in linkage with the plate trigger. When the cam slider is slided in linkage with plate trigger so as to be driven in direction by the tray drive gear meshing with a rack, a boss of the cam slider pushes a slope portion of each of cam grooves and provided in a tray, so that the tray slides to cause a rack of the tray to mesh with the tray drive gear. Thus, the tray is opened and closed by the feed motor.

  • Publication number: 20070048868
    Abstract: A liquid sample is aspirated using an aspirating tube provided with a flow path extending lengthwise in the interior of the tube, and an aspiration orifice for aspirating the liquid sample formed near the tip of the tube. The aspiration of the liquid sample to the aspirating tube is monitored during aspiration. Liquid sample is aspirated by the aspirating tube, and the collected material in the aspirating tube in the region at the tip side from the region containing the liquid sample to be used for measurement is delivered to a detecting part provided externally to the aspirating tube, and whether or not liquid sample is contained in the collected material is detected in the detecting part.
