    摘要: A cutting head for reciprocatory-type shavers comprises a mount frame carrying a shearing foil and an inner cutter driven to reciprocate in shearing contact with the shearing foil. The mount frame has a pair of opposed side bars between which the shearing foil extends in a convexly shaped manner to have its longitudinal axis extending along the apex of the shearing foil and in parallel with the side bars. The inner cutter is driven to reciprocate along the longitudinal axis and is mounted to be movable to a limited extent laterally towards the side bars. The opposite lower end or the lateral end portions of the shearing foil are secured to the outside surfaces the side bars, respectively such that each of the side bars is interposed between the inner cutter and the lower end portion of the shearing foil. Consequently, the portions can be prevented from contacting directly with and scratched or damaged by the inner cutter even when the inner cutter is forced to move laterally towards the side bar together with the shearing foil as a result of the latter being pressed against the skin of the user during the shaving operation.

    摘要: A portable type electric appliance powered by incorporated main and reserve batteries. The batteries are connected to an electric load selectively by means of a switching device including a main switch for connecting the main battery to the load and a subsidiary switch for connecting the reserve battery to the load. A lock locks the subsidiary switch in a disconnected position until the main switch is closed. Namely, the subsidiary switch can be closed only after the main switch is closed. Therefore, the main battery is always used prior to the reserve battery, and when the main battery is exhausted, the reserve battery remaining unexhausted is capable of taking over to operate the appliance without requiring immediate replacement of the main battery. Accordingly, the accidental interruption of the operation of the appliance can be avoided.
