The support shaft 26 moves to the upper end side of the elongated hole 27 having a long cross section in the longitudinal direction of the table plate 10 and stops. At this time, the outer surface of the table plate 10 on the lower end side comes into contact with the vertical holding end 28a of the upper end of the substrate 6, whereby the table plate 10 is held in the vertical state.

On the other hand, when the table board 10 is held in a horizontal state, the table board 10 is lifted and tilted sideways. When the table plate 10 is lifted, the table plate 10 rises until the support shaft 26 reaches the lower end side of the elongated hole 27 having a cross section that is long in the longitudinal direction of the table plate 10, and here the table plate 10 is tilted to the side. This makes the table board 10
Is laid down about the support shaft 26, and the surface of the table plate 10 contacts the horizontal holding end 28b of the upper end of the substrate 6 and is held in a substantially horizontal state (see FIG. 8). At this time, in the case where the horizontal holding assisting means 29 is provided on the substrate 6 side, the horizontal holding assisting means is raised to support the table plate 10 from below so that the table can be more reliably held. The plate 10 can be supported horizontally.
