  • Patent number: 11506578
    Abstract: A smear system includes smear preparing apparatus that prepares a smear slide and a smear transporting apparatus that transports the smear slide to a smear-image capture apparatus. The smear preparing apparatus includes: a smear preparation part that smeares a sample on a slide; and a smear arrangement part that places smear slides in a smear container. The smear transporting apparatus includes: a smear-container transport part that transports the smear container with the smear slides; an identification-information acquisition part that acquires identification information on whether image capturing by the smear-image capture apparatus is necessary, from each of the smear slides accommodated in the smear container positioned on a transport path of the smear-container transport part; and a smear transfer part that transfers the smear slide whose image is to be captured to the smear-image capture apparatus on the basis of the identification information acquired by the identification-information acquisition part.
