    • A ribbon cassette used for both a fabric ribbon and a film ribbon has a first slit through which a fabric ribbon is passed and a second slit through which a film ribbon is passed, the slits being provided in a wall member which partitions a downstream end of a ribbon storage chamber for storing an endless ink ribbon in a meandering state. The second slit is disposed upwardly of the first slit, and a rib for applying a load to the travel of the fabric ribbon is formed on a bottom surface in the vicinity of the upstream side of the first slit at the same position as the second slit or downstream thereto. The second slit is provided at a position biased in a direction opposite to a projecting direction of the pull-out arm and the pull-in arm from the transversely central position of the ribbon storage chamber.

    • A printed wiring board includes a core substrate having a penetrating hole, a first circuit on a first surface of the substrate, a second circuit on a second surface of the substrate, and a through-hole conductor in the hole connecting the first and second circuits. The hole has first and second opening portions. The first opening portion becomes thinner toward the second surface. The second opening portion becomes thinner toward the first surface. The first opening portion has first and second portions. The second opening portion has first and second portions. The first and second portions of the first opening portion form inner walls bending inward at the boundary between the first and second portions. The first and second portions of the second opening portion form inner walls bending inward at the boundary between the first and second portions.
