PROBLEM TO BE SOLVED: To provide a system capable of improving a reading rate of a chip tray and enhancing the reading speed.SOLUTION: The system: at first timing, reads data from chips located within a communication range and registers them in a database; at second timing later than the first timing, reads the data from the chips located within the communication range and updates the database on the basis of the read data; and at third timing later than the first timing, reads the data from the chips located within the communication range and, when it is determined that data of chips other than the read chips are registered in the database, performs communication to each of the chips other than the read chips. |
