PAGE SELECTING SYSTEM FOR ELECTRONIC ITEM/KEYBOARD DEVICE

PURPOSE:To facilitate a selecting operation in an electronic item/keyboard device with a large number of pages by selecting the pages by means of one page selection key and ten keys. CONSTITUTION:A keyboard 26 has one page selection key and one ten key and a control circuit 30 has a display pattern holding means 31 holding plural display patterns and a page selection processing means 32. When the page selection key is depressed, the page selection processing means 32 comes to a page selection mode and executes a processing displaying the display pattern corresponding to a numeric which the display pattern holding means 31 holds in a display part 22 when the numeric which is in a prescribed number of digits and which is in a prescribed range is inputted with the ten key. Since page selection is executed by one page selection key and the ten key, the enlargement of the keyboard can be prevented and the operation operation becomes simple even if the number of the pages is large.
