Abstract: An improvement in the indicator driving device for use in a television receiver incorporating a radio receiver is shown. There is provided an indicator driving device of a type in which the selection of a channel for the television receiver and the selection of a frequency for the radio receiver are performed by means of a common manipulating knob. The improvement resides in a much simplified construction and facilitation of work for obtaining synchronization or matching between the frequency selecting variable capacitor of the radio receiver and the frequency indicator.

Abstract: A battery storage compartment for selectively storing cylindrical batteries, such as dry cell batteries, or another battery of the type having a non-cylindrical end and a length different from that of said cylindrical batteries, such as a rechargeable battery. The battery storage compartment comprises a compartment member, spring means secured to one end wall of the compartment member, electrically conductive means located at the opposite end wall of the compartment and an abutment member attached to the compartment member at a location intermediate the opposite end walls and projecting from the bottom of the compartment member. The abutment member has cutout portions to accommodate the cylindrical dry cell batteries and spaced ribs which project toward the opposite end wall of the compartment member. When a rechargeable battery is placed in the storage compartment it is situated between the abutment member and the spring means.

Abstract: An antenna apparatus for use in a television receiver set or the like is provided. The apparatus has an antenna body which comprises a hollow resin cover having a plug pin integrally formed at one end thereof and an antenna pipe provided at other end thereof. An elastic conductor is mounted in the resin cover for electrically connecting the plug pin with the antenna pipe. The antenna body thus constructed can be detachably mounted on the television receiver set.
