A pivoted flap mechanism for adjusting an aerodynamic pivotable flap associated with a wing, including: an actuating device including a gear device; a drive device including a drive arm that rotates about an axis, and which is structured and arranged to load the actuating device; and a flap support composed of a leading flap support portion and a trailing flap support portion. A horizontal distance between leads of the internal electrodes of opposite polarity adjacent to each other in a stack direction is longer than a pitch between the external electrodes of opposite polarity adjacent to each other on the same side face of the capacitor body. Biometric data in dependence upon a biometric characteristic of each of the M designated persons is stored in memory of the respective portable biometric device. Plural pieces of the converted binary information are stored and then are sequentially outputted on a first-in, first-out basis. The advertising company module acquires the specification information, and transmits to the user module the component information indicating an image component specified by the acquired specification information.
