The present invention is directed to novel polypeptides and to nucleic acid molecules encoding those polypeptides. A control unit 13 is provided for generating in its basic data generator 13B basic data for imposing the payment from at least data indicative of the user identification and data indicative of the speed for recording the data read out from the optical disk 15 into the hard disk 16 and transmitting the basic data to the payment imposing unit 20. The bladder is closed off or opened relative to surrounding air in the aircraft cabin via a valve that is opened if a rate of pressure change in the cabin is less than or equal to a presettable maximum value, and closed if the rate of pressure change is greater than the value. As the result, positioning accuracy of a lens with respect to a pixel area of the solid-state image sensor dose not deteriorate even if a substrate on which the solid-state image sensor is arranged is deflected or distorted. Preferably, the fastener is rotatable while in its extended position so as to couple with the device mating portion. The actual write operations, deferred to periods of when the negative affects of the write can be completelymostly hidden.
