CONSTITUTION:A keyboard 1 as an input means, CD-ROM 2, a means 3 reading data on CD-ROM 2, an analysis means 4 obtaining the display position of the reference/retrieval key, a time measuring means 5 measuring the lapse of prescribed time, a display switching means 6 switching data displayed at every prescribed time and LCD 7 as a display means are provided. Thus, the time measuring means 5 and the display switching means 6 are provided and they operate so that they alternately switch a display screen to the case of only data and a case when the reference/retrieval key is overwritten on graphic data at every prescribed time.
