  When this displacement measuring instrument is used, first, it is confirmed that the pressure contact state between the measuring end 125A of the spindle 125 and the surface of the anvil 116, that is, that the dimension display is zero. Next, the grip portion 115C of the holding frame 115 is gripped, and the manual end portion 120B of the lifting lever 120 is pushed in the direction of the arrow. Then, the driving end 120A of the lifting lever 120 swings, and accordingly, the spindle 25 engaged with the lifting lever 120 is raised.

  As a result, a gap is formed between the measurement end portion 125A of the spindle 125 and the surface of the anvil 116. Therefore, a sheet such as a resin film is placed on the surface of the anvil 116 in the measurement space 117 and measurement is started. . In measurement, when the manual end 120B of the lifting lever 120 is pushed in the direction opposite to the arrow, the spindle 125 moves to the anvil 116 side by the reverse operation to the above, and the measurement end 125A of the spindle 125 pinches the sheet. Is pressed against the surface of the anvil 116. The thickness of the sheet is measured by reading the dimensions at this time.
