PURPOSE:To make the user of the above system free from worrying about the keeping place of the key of the system and to prevent unauthorized operation of the system, a burglary, etc., by constituting the system in such a way that the system discriminates the voice and finger print of the user and opens a door when the discriminated voice and finger print coincide with registered code information. CONSTITUTION:This door opening/closing system is constituted of a main body 1 composed of a voice registering and discriminating section 2 and finger print registering and discriminating section 3 which respectively register and store the wavelengths of the voices and finger prints of users after converting the wavelengths and finger prints into code information and a door open/close instructing signal transmitting signal 4 and a registration card 5 which is fitted to the main body 1 and on which voices and finger prints of the users are registered. When one of the users opens a door, he puts his forefinger on the section 3. When the user successively utters his voice toward the section 2, the sections 2 and 3 discriminate whether or not the finger print and voice coincide with previously registered code information and opens the door only when both of them coincide with the information. |
