Abstract
An electronic game machine 10 which is held in the hand comprises a computer 22 which is housed in a casing 12 and a liquid crystal display (LCD) panel 14 which is located on the upper part of the front surface of the casing. When an external memory 16 is connected to a receiver port 68 which is created on the back surface of the casing on a part which is directly opposite the liquid crystal display panel, first character data which is pre-installed in the computer 22 is compared with second character data which is stored in a location which is predefined by the external memory 16. Before such a comparison, the computer produces characters on the liquid crystal display panel which represent the second character data. If the first and the second character data are mutually compatible, the computer 22 can access the external memory 16. In accordance with a game program in the external memory ,during the course of the game the markers can be moved by using a direction-defining button 18 which is located below the liquid crystal display panel 14 on the front part of the casing, and the function of the markers can be defined by means of a function button 70 which is located on the right-hand side below the liquid crystal display panel. A start button 72 and a selection button 74 are arranged between the direction-defining button 18 and the function button 70. <IMAGE>
