Abstract
A method and a laminated member for measuring the dimension of a gap for passing a card therethrough are provided. A pressure measuring film is superposed on an elastic mat that gradually becomes thinner in the card-inserting direction, and passed through the gap so as to determine the dimension of the gap from the position where the pressure measuring film has started to develop a color. As the elastic mat, one that has a thickness changing in steps may be used. An alternative embodiment uses a pressure measuring board in place of the pressure measuring film, the pressure measuring board having plural pressure sensors for electrically detecting pressures applied in the direction of width. The data on the pressures detected by the pressure sensors is temporarily stored in a memory provided on the pressure measuring board, and after the passage through the gap, the contents of the memory are transferred to an external host computer via a wiring cable or in a contactless fashion via an antenna, and the pressure distribution is analyzed by the external host computer.
