The present invention relates generally to a rotary handle. The upper surface includes a recessed portion extending from the distal end portion toward the proximal end portion. On the other hand, if the pass-through flag is set to ON, the semiconductor memory device 10 does not execute writing of the data to the write-restricted area. The osmolarity of the tear sample may be used as an indicator in diagnosing dry eye. The apparatus continuously sends its position determined by GPS navigation.
