PURPOSE:To improve the efficiency and accuracy of operation by taking out electric signals from many photoelectric elements arranged in a line in the direction of nearly right angle to the carrying direction of sheet, in time series. CONSTITUTION:This device carries a sheet group, in which sheet having information on only the surfaces and sheet having information in both inside and outside surfaces coexist, through a prescribed passage for photographing. Sensor array 30 which arranges many photoelectric elements in a line in the direction of nearly right angle to the carrying direction of sheet by belt 9 is provided facing belt 9. Then, an electric signal is taken out from sensor array 30 in time series to detect the existence of information. Sensor array 30 projects optical signal upon ''SATICON '' film 33 via a transparent electrode and the electric signal from sensor array 30 is taken out in time series via switching circuit 38. |
