Abstract: With an analyzer capable of carrying out a plurality of kinds of analyses, the device is suppressed from being increased in size. The analyzer includes a first measurement unit for holding a cuvette to which a biological sample is dispensed, and performing a first measurement of a content of the cuvette; a second measurement unit for holding a cuvette, and performing a second measurement different from the first measurement of the content of the cuvette; and a transport unit for gripping the cuvette, and transporting the cuvette to an attachment and detachment position of the first measurement unit or an attachment and detachment position of the second measurement unit. The transport unit moves along a guide rail, and the attachment and detachment position of the first measurement unit and the attachment and detachment position of the second measurement unit are provided on a line substantially along the guide rail.

Abstract: A cuvette discarding unit includesa cuvette discarding container capable of discarding a cuvette from a top opening an accommodation frame capable of accommodating the cuvette discarding containerand a cuvette receiving part arranged at a top of the cuvette discarding container and having an input port into which a cuvette is charged. The cuvette receiving part has a movable cuvette receiving bottom part. The cuvette receiving bottom part is held in a retracted posture allowing the cuvette received from the input port to be charged into the cuvette discarding container at a lower position in a state in which the cuvette discarding container is accommodated in the accommodation frame, and held in a temporary receiving posture for receiving the cuvette received from the input port in a state in which the cuvette discarding container is not accommodated in the accommodation frame.

Abstract: To efficiently prevent a decrease in measurement accuracy caused by a change in a test cartridge and an environmental temperature, provided is an automatic analysis device. The automatic analysis device includes: a constant-temperature reservoir (6) to be heated by a heating source (6a) so as to keep a liquid temperature at least in the reaction cell (11c) of the test cartridge (10) in the test stage (KT) at a constant environmental temperature set previously; constant-temperature reservoir control means (7) including a temperature detector (7a), for controlling a set temperature of the heating source (6a) of the constant-temperature reservoir (6) so that the set temperature of the heating source (6a) is higher when the internal environmental temperature is lower than a previously-determined threshold value than when the internal environmental temperature is equal to or higher than the threshold value, based on the internal environmental temperature detected by the temperature detector (7a).

Abstract: A camera tube device for use in a television camera comprises an electron gun including a cathode electrode for emission of an electron beam, and first and second grid electrodes respectively having apertures for controlling the diameter of the electron beam. The aperture of the second grid electrode is sufficiently smaller than the aperture of the first grid electrode. The first grid electrode is applied with a positive voltage relative to the cathode electrode and the second grid electrode is applied with a positive voltage relative to the cathode electrode which is higher than that applied to the first grid electrode. The positive voltage applied to the first grid electrode has such a value that forms the electron beam having passed through the aperture of the first grid electrode into a laminar flow beam.
