Abstract:
1. A measurement method comprising: moving a vibrator ( moving the vibrator ( outputting a first surface contact position where the frequency of the vibrator ( moving the vibrator further towards the flat plate surface until the frequency changes a second time as the vibrator makes contact with a top surface of the main body; outputting a second surface contact position where the frequency of the vibrator changes the second time as the vibrator makes contact with the top surface of the main body; measuring thickness of the raised fabric layer of the object-to-be-measured by performing a discrimination process between the first surface contact position and the second contact position based on the frequency variation of the vibrator at the first and second contact positions; measuring a thickness of the main body of the object-to-be-measured ( moving the vibrator ( detecting and outputting a pressure of a reaction force created by the object-to-be-measured against the vibrator ( measuring a hardness of the object-to-be-measured by comparing the reaction force pressure with previously-obtained hardness information; and setting or changing various conditions including a vertical movement amount of the vibrator (
