摘要

THE PRESENT INVENTION ENABLES CONNECTION AND A HIGH-SPEED ACCESS TO A PLURALITY OF ELECTRONIC APARATUSES HAVING DIFFERENT TYPES OF BUILT -IN INTERFACES. THE PRESENT INVENTION PROVIDES AN EXTERNAL STORAGE APPARATUS INCLUDING: STORAGE MEANS (22); AN INTERFACE CONTROLLER (A21) AND AN INTERFACE CONTROLLER (B24), EACH HAVING A DIFFERENT TYPE OF BUILT-IN INTERFACE CONTROL BLOCK FOR CARRYING OUT A DATA WRITING AND/OR READING INTO/FROM THE STORAGE MEANS (22); AND CONECTION MEANS (26) FOR SELECTING AND CONNECTING ONE OF THE INTERFACE CONTROLLER (A21) AND THE INTERFACE CONTROLLER (B24) TO THE ELECTRONIC APPARATUS. IT IS PREFERABLE THAT THE CONNECTION MEANS (26) BE CONSTRUCTED SO AS TO SELECT ONE OF THE INTERFACE CONTROLLER (A21) AND THE INTERFACE CONTROLLER (B24) ACCORDING TO A CONTROL FROM THE ELECTRONIC APPARATUS.(FIG. 3)
