AUTOMATIC ANALYZER

Even when an operator wishes to confirm multiple kinds of measurement result information related to a sample, if not all of the desired information can be simultaneously displayed in a limited display area, the operator will be heavily burdened since he or she needs to execute a large number of operating steps to confirm multiple kinds of detailed measurement result information while repeating the opening/closing of subwindows and/or window-switching operations. In particular, if a measurement result alarm occurs, the operator will be unable to respond rapidly, even when he or she wishes to confirm the detailed information in an attempt to investigate the probable causes of the alarm. According to this invention, if display width of window display parts and the amount of information to be displayed at the display parts are changed according to a level of detail of the information which the operator wants to confirm, sample information, measurement results, and detailed information related to the measurement results will be simultaneously displayed without a subwindow being displayed in overlapped form in the limited display area.
