Abstract: An electric apparatus includes a power cord having first and second plug portions, and a cord portion, a plug insertion recessed portion, and a cord housing groove. The plug insertion recessed portion has an insertion surface that is formed at a position recessed inward from a side surface, and to which an inlet is attached, a first slope extending from a lower end part of the insertion surface, and a second slope extending from an upper end part of the insertion surface. In a state where the first plug part has been inserted in the inlet, a distance a from a lower end part of the first plug portion to the lower edge of the plug insertion recessed portion and a distance b from an upper end part of the first plug portion to the upper edge of the plug insertion recessed portion satisfy a relationship of a>b.

Abstract: A sheet feeding cassette includes a storage region, a front portion, and a bottom portion. On the storage region, a sheet is stored. The front portion is disposed on a downstream side with respect to the storage region in a drawing direction. On the bottom portion, the sheet is placed. In the front portion, an opening is formed through which the storage region is visible. Within the storage region, the bottom portion is formed in white or a pale color. At least a part of the visible region in the storage region is formed to be different in lightness by three or more in Munsell value from a light-color part of the bottom portion, the light-color part being formed in white or the pale color.
