PROBLEM TO BE SOLVED: To provide a texture measuring device capable of measuring a texture of an object surface with practical sensitivity and at a practical velocity.SOLUTION: A paper sheet identification device 10 includes a tactile sensor 200 and a texture measuring device having the tactile sensor 200 and a texture measuring part 30. The texture measuring part 30 measures resistance values from the tactile sensor 200 accompanying with the movement of paper money 70 through a conveyance path 60. A data processing part 36, for example, performs fast Fourier transform on the time change of measurement data and extracts frequency components. |
