Further, by setting the data format when writing the output format data to the floppy disk so that it can be accessed by an electronic terminal device or the like, the output format data can be exchanged with the electronic terminal device or the like. Thus, for example, when recording and holding various statistical analysis data measured and calculated by the center of gravity percussion meter 1 using an electronic terminal device and performing statistical / analysis processing, recording paper printed out from the conventional center of gravity percussion meter 1 is used. Based on the above, it becomes possible to greatly simplify the work of manually inputting various analysis data to the electronic terminal device, and it is possible to save the labor and time of the operator required for the input work.

Further, since the center of gravity sway meter 1 is provided with the output format generating means 44, the output format generating means 44 includes the calculating means 41 and the XY coordinate position storing means 4.

Therefore, it is possible to output (record / display / print) the various analysis data at the time of eye-opening measurement of the same subject and the various analysis data at the time of eye-closing measurement in parallel, so that data can be organized. The time and labor required can be shortened, and when performing comparative diagnosis of various analysis data when the same subject is in the open / closed state, when performing eye-opening measurement separately printed on recording paper as before. It is not necessary to make a diagnosis by comparing the various analysis data in and the various analysis data in the closed eye state with each other, and it is possible to prevent misdiagnosis due to misunderstanding of the analysis data value and to minimize the movement of the gaze of the diagnostician. Therefore, the burden on the diagnostician can be reduced.
