A printing apparatus and a printing method with the object of preventing the feed of a sheet that is not the feeding target when performing sheet re-feeding. Leading ends 4 of optical fibers 3 are fitted respectively in the through holes 2. The main rectification circuit and the auxiliary rectification circuit are both connected to the secondary winding and produce output voltages having different magnitudes. The invention provides the optimal, \u201ccanonical\u201d form for the two stroke oscillating engine of unique strength and compactness.
