A signal transmitting device for transmitting signals from operating switches which are provided on a steering wheel of an automobile to an electric load provided on a body thereof, is disclosed. The device comprises one annular electrode which is provided on a lower end surface of a steering wheel boss rotating with the steering wheel and another annular electrode which is provided on an upper end surface of a steering column cover fixed to the body so as to be opposed to the one annular electrode. These annular electrodes form a capacitor. The device further comprises a signal generating circuit composed of a plurality of resistors having different resistance values which are selectively connected to the one electrode provided on the steering wheel by use of the above described switches, an RC oscillator circuit composed of the above described capacitor which is connected to another annular electrode on the steering column cover and a signal receiving circuit which detects the change in output frequency of the oscillator circuit. The signal generating circuit is provided on the steering wheel while the oscillator circuit and the signal receiving circuit are provided on the body. By operating the switches, the resistor to be connected to the electrode provided on the steering wheel is changed so that the impedance of the line including the capacitor is changed. As a result, the output frequency of the oscillator circuit is changed by steps.

A picture combining apparatus for concurrently using a single shooting television camera to pick up still pictures such as titles. In the picture combining apparatus, the level of a luminance signal in a still picture signal generated from the television camera is compared with a threshold level to generate a binary signal corresponding to the difference therebetween and the binary signal is stored in a memory. At a given time during the shooting of a background the content of the memory is read so that the binary signal is provided with a particular color or luminance level and is superimposed on a background picture signal from the camera. Thus, the camera generates an output signal corresponding to a picture comprising the still picture superimposed on the background.
