The biorhythm recording unit contains stepping motors to record psychic rhythm, emotional rhythm and intellectual rhythm and has digital switches to input the person's date of birth and the number of months of the recording period. Discs connected to the driven shafts of the stepping motors have eccentric crankpins. Converters change the circular movements of the motors into to-and-fro movements by piston rods. A control unit stores the input data and calculates guide numbers for the biorhythms and sets off pulses which start the pen recorder. |
