4 and 5, the separation distance from the central axis C1 of the rotating bar 20 to the first guide rail 61 gradually increases from the first point P1 to the second point P2. It can be made to grow.

In this case, as the main tray 30 rotates and approaches from the position of the first point P1 to the position of the second point P2, in other words, the first pivot part 41 moves toward the first point P1. The angle between the main tray 30 and the driven tray 40 increases as it moves from the position of to the position of the second point P2 along the circular track of the first guide rail 61 and approaches the second point P2. It has an increasingly larger section (hereinafter referred to as a 'first section').

And, as the main tray 30 rotates and approaches the position of the first point P1 from the position of the second point P2, in other words, the first pivot part 41 moves toward the position of the second point P2. As it moves from the position to the position of the first point P1 along the circular orbit of the first guide rail 61 and approaches the first point P1, the angle between the main tray 30 and the driven tray 40 gradually increases. It has a smaller section (hereinafter, referred to as a 'second section').

In this way, the angle between the main tray 30 and the driven tray 40 gradually decreases in the first section while the first pivot part 41 moves from the "first point P1 to the second point P2". A larger motion is implemented (ie, see the counterclockwise rotation motion leading to "Fig. 4 -> Fig. 5").

In addition, the angle between the main tray 30 and the driven tray 40 gradually increases in the second section while the first pivot part 41 moves from the "second point P2 to the first point P1" The motion is implemented (ie, see the counterclockwise rotation motion leading to "Fig. 5 -> Fig. 4").
