A fax/copy key ( 61 ) is positioned in the center of a cover ( 130 ) of a control panel ( 60 ). When the cover ( 130 ) is closed, a plurality of one-touch speed dial keys ( 62 ) are arranged under the fax/copy key ( 61 ). In other words, the fax/copy key ( 61 ) and the one-touch keys ( 62 ) are superposed. At a pivot of the cover ( 130 ) is positioned a cover sensor ( 65 ) to detect the open/close status of the cover ( 130 ). When the fax/copy key ( 61 ) is depressed while the cover ( 130 ) is closed, several one-touch keys ( 62 ) are depressed via a plurality of protrusions ( 61 b) of the fax/copy key ( 61 ). Because the cover ( 130 ) is closed, the depression of the one-touch keys ( 62 ) is interpreted as the depression of the fax/copy key ( 61 ). This contributes to miniaturization of the operational input unit ( 60 ). |
