A video image is displayed on an image screen of a cathode-ray tube. The image screen is partitioned into a plurality of character areas, each character area is composed of four display blocks, and each character of the video image is displayed in one character area. Also, a plurality of pointer characters respectively arranged in a position of a font area are stored in a pointing character storing unit, positions of the pointing characters differ from each other, and the position of each pointing character corresponds to a position of one display block in one character area for each character area in cases where the font area of the pointing character corresponds to the character area. Also, a touch screen panel partitioned into a plurality of input blocks is prepared, and each input block corresponds to one display block of the image screen. When a user selects a particular input block, a particular display block of a particular character area and a particular pointing character are selected by the control circuit on condition that a position of the particular pointing character in the font area corresponds to a position of the particular display block in the particular character area, and the particular pointing character is displayed in the particular display block of the image screen. Therefore, the pointing character can be displayed in every display block of any character area.
