<p>PURPOSE:To prevent giving an improper production command by transporting a corresponding production command card together with a work, reading the data thereon when a main and an aux. location sensor group have sensed that the work with card is in the information read position, and thereby feeding a correct production command. CONSTITUTION:A production command card 22 is transported together with a work by a belt 20, and will pass through a vessel 24 without skewing. When this card 22 is judged to be in the information read position by the outputs of main and aux. location sensors 42A, 42B, 44A, 44B, the information code read sensors 38A-38I will read the production command data and output it. If the card 22 skews over a certain allowable angle, at least one of the aux. location sensors 44A, 44B senses off the card 22 even though the main location sensors 42A, 42B have sensed that it is in the information read position, and then an output stop command about the production command information is emitted to a card read device 26 so as to avoid giving improper production command information.</p> |
