PURPOSE:To output data from one output part to respective data display devices successively and to display them by providing each data display device with a data holding function and by utilizing the functions of its sequence controller. CONSTITUTION:At a display processing time, an arithmetic part 41 sets digital, which is data to be displayed on the 1st data display device 5, in a data output part 42. Then, a latch signal for holding the digital data in the data display device 5 is set in a latch signal output part 42. Consequently, the 1st data display device 5 holds and displays the digital data. The arithmetic part 41 resets the latch signal on condition that a time required for holding the data passes. |
