PURPOSE:To easily discriminate a cut-and-connected ticket by discriminating the presence/absence of a lost part on paper sheet at every small area from transmitted light quantities and comparing the number of small lost areas with a specific value after calculating the small lost areas in the longitudinal and lateral direction of the paper sheet. CONSTITUTION:Paper sheet 10 is divided into small areas and transmitted light data are read by means of a transmitted light sensor section 1 at every small area. The section 1 samples data by a required number of times as the paper sheet 10 is carried under the control of a central processing unit 7. A picture pre-processing section 4 binarizes the sampled data after the data are converted into digital values and a cut-and-connected ticket checking section 5 checks the weighted picture data for cut-and-connected tickets. |
