摘要： Provided are an automatic analyzer that can decrease waiting time for a user and reduce running costs as compared with in the past and an operation method for the automatic analyzer. The analyzer includes: a first mechanism group that is used only in analysis for biochemical items; a second mechanism group that is used only in analysis for immunological items; a common mechanism group that is used in analysis for both biochemical items and immunological items; and a control part that activates the second mechanism group and common mechanism group without activating the first mechanism group when analysis for biochemical items is not required, and activates the first mechanism group and common mechanism group without activating the second mechanism group when analysis for immunological items is not required.

摘要： Provided is an automatic analyzer which does not require a preparation operation of disposing of a reaction vessel on the apparatus in advance and is capable of efficiently performing shifting to an analysis operation.
In a reaction promotion unit 108, a holding position located at a reaction vessel disposal position 202 during a first operation cycle is moved to a reaction vessel setting position 201 after an n (n: integer) operation cycle, and from a first operation cycle to an n-th operation cycle, an expendable item transport unit 112 performs an operation of disposing of a reaction vessel from a disposal position without performing an operation of setting the reaction vessel at a setting position in each operation cycle, and performs an operation of setting the reaction vessel at the setting position and an operation of disposing of the reaction vessel from the disposal position in each operation cycle after an (n+1)-th operation cycle.

摘要： There is provided a technique that can efficiently control disposal and use of containers of an automatic analyzer. An automatic analyzer includes a controller, a container retaining mechanism (incubator), a dispensing mechanism, a detection mechanism, and a transfer mechanism. The dispensing mechanism includes a liquid surface detection mechanism. The controller uses the dispensing mechanism at a prescribed timing to detect the presence or absence of the liquid surface at a target position on the container retaining mechanism to determine a state including the presence or absence of the container accommodating a reaction solution. The controller performs control in which the operation of disposal using the transfer mechanism is performed at a position when a state is determined in which the container is present, and the operation of disposal using the transfer mechanism is not performed at the position when a state is determined in which the container is not present.
