The present invention relates to a space-diving apparatus that could well be preferably applied to a single-leaf section, a divider etc. A division plate section 110 constitutes a single-leaf screen device 100 and divides a space. On a front surface of the division plate section 110, nine TV receiving sets 131-1 through 131-9 are arranged in a matrix shape and an attachable/detachable manner. These TV receiving sets 131-1 through 131-9 can be detached and individually used. If the TV receiving set is detached, a decorative sheet is arranged to a position where this receiving set has been arranged. On a back surface of the division plate section 110, nine image pickup elements are mounted to, for example, positions that correspond to the TV receiving sets 131-1 through 131-9, respectively. 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 131-1 through 131-9, thereby permitting the user to observe the other side of the division plate section 110 easily.
