  • Patent number: 10598677
    Abstract: A smear transporting apparatus transports a smear slide on which a sample is smeared to a smear-image capture apparatus. The smear transporting apparatus includes a smear-container transport part that transports a first smear container accommodating smear slides to a smear pickup position; a smear transfer part that picks a smear slide whose image is to be captured by the smear-image capture apparatus from the first smear container transported to the smear pickup position, transfers the smear slide to the smear-image capture apparatus, and places the smear slide whose image has been captured by the smear-image capture apparatus in a second smear container different from the first smear container; and a storage that stores the first smear container and the second smear container.

  • Patent number: 10234364
    Abstract: First and second racks each has fixed positions to hold sample tubes. First and second drawers slide into and out of the case, and that support the first and second racks, respectively. A tube set unit is provided in an area close to the first rack in the case. A tube transfer unit removes sample tubes from the first and second racks in the case and a controller that controls a transfer operation of the tube transfer unit. The first rack is supported by the first drawer such that the first rack leaves a transit location in the case behind the first drawer in the direction of the first drawer movement into the case. The controller controls the tube transfer unit to remove at least one sample tube from the second rack and transfers the tube to the tube set unit via a path traversing the transit location.
