Abstract:
1. A movement restriction device that restricts movement of a transfer unit when the transfer unit is moved onto a chassis, the movement restriction device being provided in a processing device, the processing device comprising: the chassis; the transfer unit movably arranged on the chassis and adapted to transfer an object to be transferred onto the chassis; and a processing portion arranged on the chassis to process the object to be transferred that has been transferred onto the chassis by the transfer unit, the movement restriction device comprising: an engaging portion provided in either one of the chassis or the transfer unit; and a locking portion provided on the other one of the chassis or the transfer unit, the locking portion being detachably engaged with the engaging portion such that a restoring force due to elastic deformation is applied to the transfer unit relative to the chassis in a moving direction of the transfer unit and in at least one direction crossing the moving direction, when the transfer unit is moved to a processing position where the object to be transferred can be processed by the processing portion, the locking portion restricting the movement of the transfer unit relative to the chassis, wherein the engaging portion applies a restoring force due to elastic deformation at least either in the moving direction of the transfer unit or in at least one of directions crossing the moving direction, while the engaging portion is engaged with the locking portion, and the locking portion applies a restoring force due to elastic deformation in a direction different from the direction in which the engaging portion applies the restoring force due to the elastic deformation, while the locking portion is engaged with the engaging portion.
