A method and apparatus for image reading and image forming. Each first layer data item is decodable to be rendered as a portion of the media content. At the time of regeneration, such a portion of the membrane sheet that corresponds to the solid-liquid separating area is cut off and, after that, a new membrane sheet is lapped on the embrocation and the new membrane sheet and the embrocation are deposit fixed by a laser. A plugged-through-hole printed wiring board prepared of the resin composition does not cause defects such as hollows, cracks, blisters, peelings and so on, is excellent in solder-resistance, does not corrode a metal part, and can produce an appliance of high reliability and long life which does not occur short circuit and poor electrical connection. A pressing mechanism includes pressure caps engaging dramatically opposite points on the outer surface of the enlarged bearing portion at locations where the beating portion is to be broken and divided when a wedge is forced into the split mold. In the electrical series terminal, when the test plug is inserted into the test opening, elastic contact legs of the second end regions are bent back relative to one another and which together form a second elastic contact region for holding the contact plug of a test plug.
