とを特徴とするシート状物質の特性測定装置。 In an apparatus for measuring the characteristics of a sheet-like object running within the sensor interval, in which sensors are installed facing each other at a predetermined interval, prior to measurement, the signal of the sensor regarding the sheet-like object running within the sensor interval is measured by frequency analysis means. Frequency analysis is performed to determine the period of fluctuation in the flow direction of the sheet-like material, and when a specific frequency component is found, a sampling period calculation means is used to calculate a frequency twice the specific frequency component as the sampling period. The data collection timing based on the sampling period is selected using a timing selection means to be a data collection interval of 1/2 or less of the fluctuation period, and outputted as a set value to the data retrieval means, and data is retrieved based on the set value at the time of measurement. A characteristic measuring device for a sheet-like material, characterized in that the characteristic of the sheet-like object is calculated by a calculating means from data taken out from the means.
