ABSTRACT:
A copying machine has a top wall with a slit which remains covered during a copying operation by a board for carrying an original to be copied. When the machine is not in use, the board can be moved so as to expose the slit. The slit is elongated transversely to the direction of motion of the board and a passage is provided under the top wall and through a reflector member such that a tubular cleaner member can be not only inserted through the slit to reach an internal component such as the charger wire which requires cleaning but also moved transversely along the slit. Thus, the internal component can be cleaned without removing the top wall.
