Patent ID: 7591625

Claim:
A carrying mechanism, comprising: a first parallelogram link mechanism; and a second parallelogram link mechanism formed by using a given link of the first parallelogram link mechanism, the second parallelogram link mechanism having four sides with an equal length and being extendable and retractable linearly in a predetermined direction, wherein a first restrained link constituting the first parallelogram link mechanism and a second restrained link constituting the second parallelogram link mechanism are configured to rotate in a state such that the first and second restrained links are restrained at a given angle at one end of a common link shared between the first and second parallelogram link mechanisms, and a first restrained link constituting the first parallelogram link mechanism and a second restrained link constituting the second parallelogram link mechanism are configured to rotate in a state such that the first and second restrained links are restrained at a given angle at the other end of the common link shared between the first and second parallelogram link mechanisms, and the carrying mechanism comprises a carrying arm member configured such that the carrying arm member rotates in such a state that the carrying arm member is restrained at a given angle relative to an opposed link opposed to the common link in the first parallelogram link mechanism, at a pivot of a given end of the opposed link.
