Abstract: An information storage apparatus having internal structure and arrangement of fans in consideration of cooling effect, thereby the capacity of the entire apparatus can be smaller than that of conventional apparatus, and an optimum air channel can be formed so as to prevent damage to reliability of performance, life and the like of components at high temperatures. For a module with reliability of life or the like to be ensured or a module including a part influenced by performance such as information processing speed, provided is an arrangement where outside air is directly forwarded to the module. Further, a module which does not produce much amount of heat and does not require cooling is provided in a comparatively front stage of the channel, a module including heat-producing components and a cooling fan is provided in a comparatively rear stage of the channel.
