A laminating water-based surface treatment agent according to the present invention includes a chitosan derivative, a carboxyl compound having at least one carboxyl group in a molecule, and water. In one configuration of the imaging device, the image sensor is placed remote from the remaining image processing circuitry. The axially oriented element defines sectional regions in the core. After the holes are punched the slugs are pushed back into the holes and the document is retrieved by the operator. The shaft portion penetrates the through hole to be locked into the locking hole member, so that the head portion and the shaft portion are respectively positioned on the top side and the down side of the bottom portion. The natural invigorating tea may be in the form of powder, liquid, or granules and is made of parasitic herb, and alder andor schizandrae fructus, optionally supplemented with torilis fructus andor polygalae japonica herba.
