Patent number: 6568447Abstract: The cover glass adhering device is capable of dropping fixed amount of mounting medium, using cover glasses having various length, and being small in size. In the cover glass adhering device, a drop nozzle drops the mounting medium onto a specimen on a slide glass, which is held horizontally. A removing member removes a drop of the mounting medium dangling from the drop nozzle. The removing member is located outside of the slide glass. A traveling unit travels the drop nozzle, from which the dangling drop of the mounting medium has been removed by the removing member, along the specimen on the slide glass so as to drop a prescribed amount of the mounting medium over the specimen.Type: GrantFiled: May 5, 2000Date of Patent: May 27, 2003Assignees: Kabushiki Kaisha Tiyoda Seisakusho, Sakura Finetechnical Co., Ltd.Inventors: Takayoshi Sakai, Shinji Tokudaiji, Takashi Yoshiike, Kiyokazu Iijima, Seiichi Takizawa
