Abstract
An information signal transmitting device which can transmit a large amount of information rapidly and readily with a simplified construction of a reduced size and can be produced at a reduced cost. The device comprises a movable unit and a fixed unit between which an information signal is transmitted using an electromagnetic wave or an ultrasonic wave as a transmitting medium. The movable unit includes a signal receiving means for converting an information signal transmitted from the fixed unit into a binary signal, a shift register for storing an output of the signal receiving means therein, and a signal transmitting means for transmitting one bit of an information signal outputted from the shift register. The fixed unit includes a signal receiving means for converting an information signal from the movable unit into a binary signal, a signal transmitting means for transmitting an information signal to the movable unit, a data setter on which an information data is to be set, and a sending and reading controlling means for alternately sending one bit of the information data set on the data setter to the signal transmitting means and reading one bit of an output of the signal receiving means.
