A magnifier-and-focus switching unit switches the focal distance of an image acquiring unit and an object from a focal distance for normal photography to a focal distance for close-up photography. A divider divides the image into plural regions by using the separation degree of feature quantities of pixels for composing the image. The box portion is designed for receiving items to be transported over the road. In a second embodiment, an adjustable support bracket is movably mounted to each support wall to replace the steps so that the sheet material can be supported on edge at various heights. An edge of each resonator is mechanically coupled to an edge of another resonator and the plurality of resonators expand and contract reaching resonance in response to an applied electric field.
