The invention relates to a fuel-metering arrangement for the mixture-forming unit of an internal combustion engine in a portable handheld work apparatus. The developing device is configured to change between a contact state where the photosensitive drum and a developing roller are in contact with each other and a separation state where they are separated from each other. The hinge is assembled to the liquid crystal panel. At least some column attributes of the plurality of column attributes include values updated relative to corresponding column attributes in the source table of values. The plasma discharge circuit includes an energy accumulating section, and an energy supplying section configured to supply the electric energy to the energy accumulating section during a short time period immediately before the breakdown discharge circuit applies the first voltage to the ignition plug. Thus, when viewed from the side, an ideal connection line through the two spaced fastenings forms a swiveling axis for the pivotal upper edge region of the covering.
