Referring to FIG. 2, the detailed structure of the operation button will be described. Here, the operation button 30 will be described. The operation button 30 includes a fixed portion 32 into which the rear end of the operation rod 24 in the insertion direction is pressed, and a first position for pressing the operation rod 24 in the insertion direction (the direction of the arrow 12) and the frame 20.
The rotation unit 34 is configured to rotate away from the first position (see FIG. 1) and between a first position and a second position substantially orthogonal to the first position. In FIG. 2A, the rotating portion 34 when located at the first position is indicated by a two-dot chain line, and the rotating portion 34 when located at the second position is indicated by a solid line. By rotating the rotating unit 34 to the second position with the PC card inserted into the frame 20 (see FIG. 1), the terminal of the PC card dedicated terminal on which the ejector unit 10 is mounted It is possible to prevent a reduction in the mounting density and an erroneous operation of the operation rod 24. In addition, when the rotation part 34 is located at the second position and the rotation part 54 of the operation button 50 (see FIG. 1) is located at the first position, the operation button 50 is pressed in the insertion direction and an erroneous operation is performed. Even if the operation button 30 is not pressed,
