An automated analyzer includes a conveyance mechanism to convey a specimen, an analysis portion to analyze the specimen, and a device cover to cover a movable mechanism including the conveyance mechanism. The automated analyzer is provided with an interlock mechanism and an interlock release mechanism. The interlock mechanism stops an operation of the movable mechanism when the device cover is opened. The interlock release mechanism disables all or part of the interlock mechanism. The interlock mechanism is enabled when a leveris in contact with a safety switch. The interlock mechanism is disabled or partially disabled when the leveris not in contact with the safety switch. This enables to prevent a user from inadvertently touching the movable mechanism including a hazard region during analysis of the automated analyzer or a maintenance task. Only a specific maintenance task can be performed with the device cover opened.
