Abstract
Abstract An electrical apparatus is provided in which in the situation as shown in FIGS. 1-4 in which power inlet pins are exposed, a user can use the electric appliance by connecting A.C. cord 20 to power inlet pins 5 without danger that a user might touch slide plugs 4 because they are completely covered by slide cover 7. In this situation, if a user pushes finger actuating portion 8 of slide cover 7 in the direction as shown by an arrow in FIG. 4, power inlet pins 5 are covered by slide cover 7 and slide plugs 4 protrude out of plug slits 32 by rotation of pinion gear portion 3 which engage with rack gear 17 and 18 as shown in FIGS. 5 and 6. In this situation, the electric appliance can be charged with slide plugs 4, while power inlet pins 5 are covered by slide cover 7, so that there is no danger that a user might touch power inlet pins 5.
