PURPOSE: To request menus with easy operation without performing complicated selecting operation by successively displaying select menus in the lowest order, whose frequency in selection is high, in the order of request frequencies before request operation. CONSTITUTION: For example, request history 'KDKDKHKDKE' is recorded in a request history memory 310. In this case, a select menu K has the highest frequency in selection, and a select menu D has the next highest frequency in selection, and select menus H and E nave the lowest frequency in selection. In accordance with the command of a central processing unit 30, a request frequency analysis circuit 311 analyzes recorded contents of the request history memory 310 and inputs data of request frequencies to the central processing unit 30. When a command is inputted from a controller 33, an analysis circuit 31 displays the select menu having the highest frequency in request on a display device 34 based on request data recorded in the request history memory 310. |
