- a consumable supplies supply unit for example, a reaction vessel tray 112, a first reaction vessel transport unit 113, etc.
- the consumables supply section includes a first consumables holding section (e.g., main tray 132) capable of holding a first consumables storage container that stores a plurality of consumables;
- a second consumables holder e.g., buffer tray 133) that can hold a second consumables storage container, and an analyzer that stores the consumables in the first consumables holder and the second consumables holder.
- a transport mechanism for example, the first reaction container transport unit 113 for transporting the first consumables to the first consumable holding part, and the control unit controls the first consumable holding part to be accessible by the operator during the analysis operation in the analysis part.
- the structure is configured to allow access by the operator to the parts, it is possible to suppress the increase in size and cost of the apparatus and to replace consumables without interrupting the analysis operation.
- the present invention is not limited to the above-described embodiments, and includes various modifications and combinations within the scope of the invention. Furthermore, the present invention is not limited to having all the configurations described in the above embodiments, but also includes configurations in which some of the configurations are deleted. Moreover, each of the above-mentioned configurations, functions, etc. may be realized in part or in whole by, for example, designing an integrated circuit. Furthermore, each of the above configurations, functions, etc. may be realized by software by a processor interpreting and executing a program for realizing each function.
