Abstract:
A method for measuring a dimension of a gap for passing a card therethrough, comprising the steps of:(a) providing a laminated member comprising a pressure measuring board and an elastic mat, the pressure measuring board having plural pressure sensors arranged substantially in a direction in which the card is inserted into the gap to electrically detect a pressure applied in the direction of a thickness of the respective pressure sensors, the elastic mat being superposed to cover at least said pressure sensors, a thickness of the elastic mat increasing from a front end of the mat to a rear end of the mat along the direction in which the card is inserted into the gap;(b) passing said laminated member through said gap;(c) storing the pressures detected by said plural pressure sensors; and(d) after the passage of said card through said gap, reading the stored pressures from the laminated member to determine the dimension of said gap.
