A multilayered printed circuit board includes a first surface layer that includes a semiconductor integrated circuit, a second surface layer that includes a bypass capacitor and that is opposite to the first surface layer, a main power supply wiring layer, and a ground layer between the first and second surface layers. The height of the ramp increases toward the fastening station, and the end of the ramp that is located in proximity of the shoulder station forms a break-off edge that is disposed at a predetermined distance from the outer side of the external load that is directed toward the break-off edge, in order to influence pitch moments and yawing moments of the external load. The dispenser can also be powered by a solar panel, either in addition to or in place of, the batteries. A convex lens, through which the beam passes, has a focus lying in the said common focal plane. Thus, even after the plural image output devices for performing the image output are specified, distribution control based on the distribution priority order for the plural image output devices is enabled.
