PROBLEM TO BE SOLVED: To eject a circuit board from a card holder using simple operations and a simple structure. SOLUTION: A first power transmission part 221 and a second power transmission part 22 are provided at the tip part of a ejection operating rod 200 having a determined space with respect to the moving direction. A first lever 310 having a fulcrum 313 closer to a working end part 312 and a second lever 320 having a fulcrum 323 closer to a power receiving end part 321 are supported on a back board 100, so that the first power transmission part 221 first abuts on the power receiving end part 311 of the first lever according to the movement of the ejection operating rod 200, and the second power transmission part 222 then abuts on the power receiving end part 321 of the second lever. The working end part of the first lever abuts on the first working force receiving part projection 441 of a card ejecting slider 400 and causes it to pull out the circuit board abutting on card contact hooks 431 and 432 move from a connector, and the working end part of the second lever abuts on the second working force receiving part projection 442 of the slider to make the circuit board move further. |
