The circuit board packaging structure capable of inserting and extracting an interface part of a circuit board into and from a connector part of the processing equipment in a direction different from a direction of attaching and detaching the circuit board to and from the processing equipment includes: an operating part which turns on receiving force; a plate part which is fixed to the circuit board to be rotatable in a direction reverse to a turning direction of the operating part, and converts the force received by the operating part to force in a direction different from the attaching and detaching direction to move the circuit board in that direction; a link part which connects the operating part with the plate part to transmit the force received by the operating part to the plate part; and a fastener which fastens the circuit board and the operating part with play.
