At this time, the first abutting surface 15 on the convex portion 12 of the rotating member 10 and the elastic member bracket The second abutment surface 15 of the upper edge 50 moves in a direction away from each other, the elastic member holder 50 moves downward, and the elastic member (or spring) 40 is thus compressed, which functions to slightly support the cover of the scanner. Therefore, when the cover is not covered, the impact force is too large to cause an excessive impact on the scanning platform.

During the process of picking up the cover of the scanner, such as scanning During the process of closing the cover from the closed state to the raised state, the flip cover will drive the rotating member 10 fixedly connected thereto, and the pivoting member 12 of the rotating member 10 is pivotally connected with the pivoting member 21, and the rotating member 10 will follow the pivot. The axial direction (such as the X direction) of the rotating member 21 is rotated. At this time, the first abutting surface 15 on the convex portion 12 of the rotating member 10 and the second abutting surface 15 of the upper edge of the elastic member bracket 50 are close to each other. Direction Moving, the elastic member holder 50 moves upward, and the elastic member (or spring) 40 elongates and releases the elastic energy, making the lid lift more labor-saving.

Whether in the process of the cover from the pick-up state to the closed state Or in the process of the cover from the closed state to the lifted state, while the rotary member 10 is pivoted, the fixed portion 251 of the rotary connecting member 25 fixedly connected thereto is driven, and the pivoting portion 252 of the rotary connecting member 25 is also Therefore, pivoting is performed along the axial direction of the pivot member 21 (such as the X-axis direction). When the flip cover is at an angle to stop lifting or closing the flip cover, the friction between the pivoting portion 252 of the rotary link 25 and the elastic pieces 24, 26 can support the cover so that the cover remains fixed to a certain angle.
