<p>PURPOSE:To release an operator from troublesome screen switching operation and to improve the operability by lowering display priority by one stage each time a display switching time is elapsed and additionally displaying data having the corresponding display priority on a screen. CONSTITUTION:The elapsed time T corresponding to an elapsed time signal St measured by a time measuring means 11 is compared with the display switching time Ts set previously in the display switching time setting register Rt of a data display means 12; when (elapsed time T) >= (display switching time Ts) as a result of the comparison, the display priority stored and held in an internal display priority holding register is lowered in stages and a reset signal Srst is sent out. A display means 13 is equipped with an image memory inside, rewrites the image memory as to data transferred from the means 12, and makes a display on the screen on the basis of the storage contents of the image memory.
