Device for guiding plate-like object

A guide apparatus for guiding a movement of a plurality of doors with respect to a main body between a set position and a preparation position that is in front of or behind said set position and between said preparation position and a non-set position positioned at a side of said preparation position, wherein said plurality of doors are flush with each other in said set position and when arranged side by side, said guide apparatus comprising:

• a roller mounted on at least one of upper and lower edge portions of each of said plurality of doors;
• and
• a plurality of rotatable rails having a length approximately equal to a width of said plurality of doors and arranged in a line extending horizontally in a left and right direction,
• wherein each of said plurality of rotatable rails is supported by said main body such that said plurality of rotatable rails rotate between a first rotation position and a second rotation position about a first rotation axis extending horizontally in the left and right direction,
• wherein each of said plurality of rotatable rails includes a supporting surface, an auxiliary track, and an additional track,
• wherein in said first rotation position, each of said plurality of rotatable rails supports a corresponding one of said plurality of doors in said set position by making said roller ride on said supporting surface,
• wherein in said second rotation position, each of said plurality of rotatable rails supports a corresponding one of said plurality of doors in said preparation position by making said roller ride on said auxiliary track, and
• wherein when one of two adjacent ones of said plurality of rotatable rails is in said second rotation position, a surface of said auxiliary track of said one of two adjacent ones of said plurality of rotatable rails is coplanar to a surface of said additional track of the other of said two adjacent ones of said plurality of rotatable rails in said first rotation position.
