Abstract

PURPOSE:To make a device small-sized without requiring a keyboard, by providing a page selection area, and changing over a selection item. CONSTITUTION:When a data of a selection data display area 3 is detected by a light pen 6, its signal is provided to a light pen detecting circuit 12, and is inputted to a controlling circuit 11 as a position information. The circuit 11 reads out the data of the corresponding area 3 from a display buffer 8, writes it on the buffer 8 corresponding to the position of a cursor 5 of a display area 2, and also displays it on a CRT10 by a displaying circuit 9. On the other hand, in case a display data of a page selection area 4 has been detected by the pen 6, if a position information is provided to the circuit 11, a corresponding data is read out from the buffer 8, an item group corresponding to its page is read out by a memory circuit 7, and written in the area 3, and a selected item is replaced.
