  Note that, as a result of the search performed by the search unit 351 in step S <b> 13, if the operation history corresponding to the operation history request from the user terminal 5 cannot be acquired, the server 3 transmits an error message to the user terminal 5. You may do it. In this case, the display unit 51 of the user terminal 5 that has received the error message displays and outputs the error message received from the server 3.

  Further, an operation history request may be input from the input unit 31 of the server 3 itself, and the search result (operation history) may be displayed and output by the output unit 32 of the server 3.

  According to the first embodiment of the present invention described above, the operation information input by the automatic analyzer is automatically transmitted to the server via the communication network, and is stored and managed on the server side. The server transmits the operation history of the automatic analyzer according to the transmission request from the user terminal to the user terminal.
