Abstract: An examination apparatus examines a specimen using a liquid container which accommodates a liquid and of which an opening portion is sealed with a sealing film. The examination apparatus includes: a perforating mechanism that perforates the sealing film with a perforating tool; and a camera that captures an image of a scattered state of the liquid on a front surface of the sealing film in a case where the sealing film is perforated with the perforating tool, and outputs a captured image.

Abstract: The perforating tool includes: a shaft portion that is pierced through the sealing film and has a rod shape extending from a front end side to a base end side; and a large diameter portion that is formed at a front end portion of the shaft portion, the large diameter portion having a diameter of a circumcircle, which circumscribes an outer shape of a traverse cross section orthogonal to an axial direction, greater than a diameter of a circumcircle, which circumscribes an outer shape of the traverse cross section of the shaft portion, wherein, a length from a front end of the shaft portion to an end portion of the large diameter portion on the base end side is shorter than a maximum insertion depth of the shaft portion into the container.

Abstract: The examination apparatus includes a dispensing unit that includes a nozzle; a liquid tank that stores the first liquid or a second liquid; a heater that heats the first; and a processor that is configured to maintain a temperature of the heater at or above a predetermined first temperature during a period from end of the examination of one specimen to start of the examination of a next specimen, and measure a waiting time from the end of the examination to the next examination, and execute, in accordance with the waiting time, a temperature control which is for compensating for a decrease in temperature caused by the waiting time, the temperature control including an empty discharge process of empty-discharging the first liquid from the dispensing unit to a place other than the reaction cell or a temperature setting change process of setting the heater to a second temperature.

Abstract: An examination apparatus includes: a detecting unit that detects a target substance; a specimen dispensing unit and a moving mechanism which moves the sampling nozzle; a nozzle imaging camera; and a processor that is configured to control the specimen dispensing unit and the nozzle imaging camera. The processor is configured to acquire an image of the sampling nozzle in a state of holding the specimen after the specimen is suctioned through the sampling nozzle and before the specimen is discharged to the reaction cell through the sampling nozzle, from the nozzle imaging camera, determine whether or not a formed element is present in the specimen, on the basis of the image, and discard an upper layer of the specimen accommodated in the specimen collection container, the upper layer including the formed element, by controlling the specimen dispensing unit in a case of determining that the formed element is present.
