Abstract

PURPOSE:To detect the oversight of the object to be inspected, by providing shift register which corresponds to the viewfield of the linear image sensor and then deciding whether the data is included within the final stage output of the shift register. CONSTITUTION:The uranium pellets 2 are arranged in a row on the roller 3 to be turned. This turn is picked up by the sensor 4 having the linear image sensor 1 to carry out an indirect appearance inspection. Then the shift register 6 corresponding to the viewfield 5 of the sensor 4 is installed, and the pellet Pn entering the viewfield is stored in the input stage of the shift register in the form of an uninspected pellet. And the data within the register 6 is shifted based onth shift of the picture within the viewfied of the sensor. When the reading is over for the picture data of the pellet Pn, the data of the register 6 is erased. Then the presence or absence is detected for the unerased data to detect the existence of the overlooked pellet.
