PURPOSE:To provide possibility of mounting and removing a printed circuit board by a single hand by installing a grip for insertion and drawout on the circuit board through two link mechanisms, and moving this grip toward the device and back therefrom to allow the circuit board to be inserted or drawn off. CONSTITUTION:A grip for insertion and drawout 14 is advanced toward a device concerned 33 in the condition that the tips of a first and second link 11, 12 are in contact with the first fulcrum 34b of a supporting part 34. Thereby a printed circuit board 30 moves toward the device 33 while the tips of the links 11, 12 working as lever function as the point of acting, and the connector 31 is coupled with the connector 32 on the device 33. When in this condition the grip 14 is retreated, the connector 31 on the circuit board 30 is drawn off while the tips of the links 11, 12 in contact with the second fulcrum 34c of the supporting part 34 function as the point of acting. Accordingly fitting and removal of the circuit board 30 to/from the device can be done only through movement of the grip 14 fore and aft by a single hand. |
