To provide a table incorporating a screen automatically moved to easy-to-see position and angle for a sitting operator.

An operator or a position where the operator holding a radio transmitter sits is detected using a human sensor disposed at the lower part of the table or a radio receiver disposed inside the table together, and an exclusive screen under a table surface is automatically moved to the front of the operator by a moving mechanism. The position at which a user sits is detected and a direction is adjusted by an angle adjusting mechanism so as to direct a shared screen to an intermediate direction between the operator and the user.
