An automatic analysis device has a plurality of types of photometers having different quantitative ranges, and an analysis control unit for quantifying the desired component in specimens based on measurement values of one or more photometers selected from among the plurality of types of photometers. The analysis control unit: sets a switching region in an overlap region of respective quantitative ranges of the plurality of types of photometers, said switching region having a greater width than does the variation in quantitative values of the desired component based on the measurement values of photometers having the same specimen; compares the quantitative value of a quantitative range portion that corresponds to the switching region and the quantitative values of the desired component based on the measurement values of the photometers; and selects a photometer to be used in quantitative output of the desired component from among the plurality of types of photometers.

To provide a reagent cooler reduced in size as compared with that in the related art by reducing a thickness of a heat insulation material of the reagent cooler, and an automated analyzer including the reagent cooler. In the reagent cooler of the automated analyzer, a vacuum heat insulation material is disposed in a periphery (on a side surface, or/and upper and lower portions) of a cooling jacket of the reagent cooler. Then, an end portion of the vacuum heat insulation material is disposed at a position shifted from upper and lower end portions and a side surface end portion of the cooling jacket and a distance between the end portion of the vacuum heat insulation material and the cooling jacket is taken as much as possible.

An automatic analyzer keeps the inside of a reagent cooler that stores a reagent vessel clean. The automatic analyzer includes: a reagent cooler that stores a reagent vessel containing a reagent to be reacted with a sample at a predetermined temperature. A reagent vessel replacement unit includes an opening configured to put the reagent vessel into and take the regent vessel out of the reagent cooler, wherein the opening is opened and closed to replace the reagent vessel. A positive pressure unit positively pressurizes the inside of the reagent cooler with respect to a periphery of the reagent cooler when the opening is opened.

This cooling box for storing a reagent and the like in a cold state, becomes a cantilever structure where, when a slide rail (104) is disposed outside a cooling space, an installation part (102) is held only by a drawer door (103). When a heavy article is placed or the like, the installation part is deformed and broken. This cooing box comprises a sliding member holder (106) provided with sliding members (200) each including a compression coil spring (202) which is an elastic body inside a heat insulating box body (101). When a reagent container (301) is installed in the installation part (102) and drawn out, the installation part and the sliding members slide in contact with each other. When a load exceeding the weight of an installed article is applied to the installation part, the installation part and the sliding member holder come into surface contact with each other. Thus, deformation and breakage of the installation part can be prevented.

A microscope for microscopic examination of a sample includes: a microscope housing enclosing an illumination optics, a microscope stage, and an imaging optics; an integrated sample chamber located within the microscope housing; and an integrated reagent chamber located within the microscope housing, the integrated reagent chamber supplying a reagent to the sample.

A reagent storage device of the present disclosure includes a shutter and a moving mechanism. The shutter is configured to open and close an opening in a reagent compartment for housing a reagent container, the reagent compartment being provided with the opening for insertion and removal of a probe used to extract a reagent from inside the reagent container housed in the reagent compartment. The moving mechanism is configured to move the shutter to an overlay position opposing the opening and separated from the opening before moving the shutter downward so as to close off the opening, and is also configured to move the shutter that is closing off the opening upward to open up the opening before withdrawing the shutter from the overlay position over the opening.

Provided is an automatic analyzer, into or out of which a reagent bottle is automatically carried, capable of reducing a burden of an operator than in the past and preventing suspension of the analyzer. The automatic analyzer includes ribs 300 in a reagent disc 9 or ribs 400 in a reagent loading unit 103, a reflection sensor 200 provided in a reagent transport mechanism 101 to detect the ribs 300 or 400, and a controller 21 that adjusts a transport parameter of the reagent transport mechanism 101 using positions of the ribs 300 or 400 detected by the reflection sensor 200.

A fluidic device holder configured to orient a fluidic device. The device holder includes a support structure configured to receive a fluidic device. The support structure includes a base surface that faces in a direction along the Z-axis and is configured to have the fluidic device positioned thereon. The device holder also includes a plurality of reference surfaces facing in respective directions along an XY-plane. The device holder also includes an alignment assembly having an actuator and a movable locator arm that is operatively coupled to the actuator. The locator arm has an engagement end. The actuator moves the locator arm between retracted and biased positions to move the engagement end away from and toward the reference surfaces. The locator arm is configured to hold the fluidic device against the reference surfaces when the locator arm is in the biased position.

An object of the present invention is to provide an automatic analyzer that can reduce manual work by an operator. The present invention provides an automatic analyzer that includes a drive mechanism that is driven to use a specimen or reagent stored in a storage member, a controller that controls the drive mechanism, and a communication unit that communicates with a work support device that performs work support to support work of loading and/or unloading the storage member. The controller controls the drive mechanism to perform a preparation operation for the work and controls the communication unit to transmit an instruction signal for the work support to the work support device.

Disclosed is a reagent container rack used in a specimen analyzer configured to analyze a specimen by use of a reagent. The reagent container rack includes a holder configured to hold a reagent container that contains the reagent; and a lid configured to cover a mouth portion of the reagent container to form an airtight space between the lid and the mouth portion.
