Patent number: 10330585Abstract: A counting device counts the number of counting objects in liquid in a flexible container. The counting device includes a mounting table on which the container is mounted and a pressing table arranged opposite to a container-arranged side of the mounting table. The mounting table and the pressing table move relatively in a direction of sandwiching the container, and a light-passing hole facing a surface of the container is provided in at least one of the mounting table and the pressing table. The pressing table includes one or more thickness-setting members that sandwich the container between the pressing table and the mounting table in a periphery of the light-passing hole and on the side opposite to the container in a protruding manner.Type: GrantFiled: December 21, 2015Date of Patent: June 25, 2019Assignee: TOYO SEIKAN GROUP HOLDINGS, LTD.Inventors: Osamu Koseki, Ryo Suenaga, Masahiro Kuninori
