With the rotation of the document table 1, the locking member 20 moves while being restricted by the projection 22 fitted into the opening 20d. Then, the projection 22 comes into contact with the locking projection 22c, and as the projection 22 gets over the locking projection 20c, the elastic portion 20e is elastically deformed outward. At this time, the rigid portion 20f hardly deforms. When the projection 22 passes through the locking projection 20c and reaches the tip end 20h, the elastic deformation of the elastic portion 20e by the projection 22 is released, and the abutting projection 20i contacts the projection 22 to limit the movement limit of the locking member 20. Become. At this time, the document table 1
It is open as shown in the figure. The open position of the document table 1 is maintained by the projection 22 abutting on the locking projection 20c and the elastic portion 20e.
