A protrusion 11 with an end face 10 facing upward is provided at a position rotated approximately 90 degrees counterclockwise.

A support member side spring mounting seat 12 is provided upright on the support member 6 below the groove 5 side with respect to the rotation shaft 8, and a coil spring 13 is interposed between it and the spring mounting seat 9 of the locking member 4. . A spring mounting seat 9 of the locking member 7 is located below the rotation shaft mounting portion of the support member 6.
The stopper 14 that the end surface of the spring interposed side abuts
is set upright to prevent the locking member 7 from rotating.

In this embodiment, with the above-mentioned configuration, when the container 2 that stores the plate-like object 1 is not placed on the support member 6 erected on the main body 4 of the plate-like object supplying device, the action of the coil spring 13 allows A rotational force is applied to the locking member 7 in a counterclockwise direction using the rotating shaft 8 as a fulcrum, and the end surface of the spring mounting seat 9 on the spring-inserted side is brought into contact with the stopper 14 to stop the locking member 7. Remains in this state unless added.

When placing the container 2 on the support member 6, the container 2
The arm member 3 is fitted into a groove 21 having the same shape as the groove 5 provided in the elevating device 20 to support the arm member 3 from below, and the elevating device 20 is gradually lowered to remove the arm member. 3 is fitted into the groove 5 of the support member 6, and the container 2 is placed on the support member 6. After placement,
Further, the lifting device 20 is lowered, and the arm member 3 is removed from the groove 21 of the lifting device 20. At the same time, the lifting device 20 is
