PURPOSE: An apparatus for moving a PC(personal computer) board is provided to be used in a conference or a lecture system using multimedia, to enlarge effective space of a narrow space, to offer convenience in a conference and a lecture, and to improve efficiency in a conference or a lecture. CONSTITUTION: A gear motor(40) rotates by the supply of power. A pulley(50a) rotates horizontally and the horizontal rotation is transmitted to another pulley(50b) of a gear box(46) via a belt(52). The speed of the pulley is decelerated in the gear box and the rotational direction is converted to vertical. A rotary shaft(44) rotates while being supported to a bearing(60) and a sleeve(48) and closes and opens the door. A motor stops if stop pins(58a,58b) touches to limit switches(60a,60b). The door is in completely opened or closed state. A PC board moving apparatus is moved to the side while the door is opened, the PC board is placed in the front. A screen is used in the front central space wherein the PC board is placed. Thus, a narrow spaced is used efficiently.
