To determine authenticity of a solid body simply and precisely, a reference area of a paper sheet which is genuine is optically read from two different directions, and the image is registered as a reference image. A check area of a paper sheet subjected to the authenticity determination, including the reference area and having a size larger than the reference area, is read from two different directions with a scanner, and data on a partial area having the same size as the reference area are extracted from each set of check data collected by the reading. For a set consisting of the reference image and the check image optically read from the same direction, the value of the correlation with the reference image is repetitively calculated by the normalized correlation method while the partial area is shifted within the check area. The maximum correlation value and the normalized score of the maximum correlation value are compared with respective thresholds to determine the authenticity of the paper sheet. If the paper sheet is determined to be “genuine” for the authenticity determination of each set, the paper sheet subjected to the authenticity determination is finally determined to be “genuine.”

It is an object of the present invention to provide a conveying apparatus which guides a conveying target object in the conveying direction while preventing it from falling off from rollers and in which intervals between the adjacent rollers can be narrowed. The present invention is a conveying apparatus comprising a plurality of rollers which are arranged in a conveying direction of a conveying target object and on which the conveying target object is to be placed, wherein the plurality of rollers include a first roller and a second roller adjacent to the first roller, the first roller comprises a first placement portion on which the conveying target object is to be placed, and a large diameter portion which has a larger diameter than that of the first placement portion and guides the conveying target object in the conveying direction, and the second roller comprises a second placement portion on which the conveying target object is to be placed, and a small diameter portion which has a smaller diameter than that of the second placement portion and prevents interference between the large diameter portion and the second roller.

An optical unit may include an image pick-up device, a lens unit and a holding member. The image pick-up device may convert a reflected light reflected from an original document to an electric signal, after the light is irradiated on the original document from a light source. The lens unit may image the reflected light on the image pick-up device. The holding member may hold the image pick-up device and lenses. The direction of a fluctuation of a focal length of the lens unit caused by heat and a direction of the fluctuation of a distance between the image pick-up device and the lens unit caused by heat may agree with each other.

A primary treating tank (10) comprises a filling layer (14) and a foam glass layer (16) below the filling layer (14). The foam glass layer (16) contains foam glass grains each of which is larger in a grain diameter than a wood chip of the filling layer (14) so that the foam glass layer (16) is superior in water passing ability to the filling layer (14). In this arrangement, a space ratio is larger with a lower layer. This arrangement promotes smooth downward shifting of primary treated water. A secondary treating tank (30) also has a laminating structure including a filling layer (34) and a form glass layer (36). As air is supplied to the foam glass layer (36), the filling layer (34) is kept in a preferable aerobic condition so that preferable aerobic biological treatment is carried out on the treated water supplied from the primary treating tank (10).

An information processing apparatus and method which allow a user to readily select, upon transmission of an electronic mail or upon uploading of image data, image data of a plurality of images to be attached to the electronic mail or image data to be transmitted. The user uses a cross key and a determination button of an inputting section of a camcorder: to operate an anchor on an image selection screen, to operate a page backward feeding button and to operate a page feeding button to select a thumbnail image displayed. In response to an operation by the user, the anchor is positioned on the side of the number of the thumbnail image designated by the user, and image data of the thumbnail image at which the anchor is positioned are selected.
