On a front surface of the division plate section, nine TV receiving sets are arranged in a matrix shape and an attachable/detachable manner. On a back surface of the division plate section, nine image pickup elements are mounted to, for example, positions that correspond to the TV receiving sets respectively, when each are detached. An imaging direction of each of the image pickup elements can be automatically aligned with a line of sight of the user based on a position of the user (position of a remote controller). An image due to a video signal obtained by each of the image pickup elements can be displayed on the TV receiving sets, thereby permitting the user to observe the other side of the division plate section easily.
