This telegraph register was made in Paris by Charles Noe, 11 Rue Laromiguiere, and used in Japan. The paper tape travels along the side of the brass housing while the drive mechanism is set within. The electromagnets are set between the housing and the electrical connecting posts. The used wound the spring-powered drive mechanism with a key. Telegraph registers are electrically-activated printers that receive Morse code messages. The message travels as a series of electrical pulses through a wire. The pulses energize the register’s electromagnets which move a lever-arm holding a pen or stylus. A clockwork mechanism pulls a strip of paper across the pen or stylus, recording the message. Short pulses draw or emboss a dot, slightly longer pulses a dash. The sequence of dots and dashes represent letters and numbers.
