In the state of being received, the gripper 530 presses the poppet 564, thereby causing the poppet spring 566 to be in a compressed state. When the holder 530 is to be pulled out from the storage state, the switch 514 is pulled to disengage the stopper 518 from the stopper groove 302. At this time, the holder 530 is lost to the top, and the spring-opening spring 566 thus pushes the spring-opening member 564. The poppet 564 1271325 pushes the gripper 530 to automatically eject the gripper 530, eliminating the need to manually pull the gripper 530, and is quicker and more convenient. When the holder 530 is received, the switch 514 is also pulled to press the fixing member 516 by the switch 514, and the blocking member 518 is disengaged from the top position, the holder 530 is pushed into the display device body 510, and the switch 514 is released. The fixing member 516 is pushed by the restoring force of the fixing spring 520, so that the blocking member 518 returns to the abutting position, that is, the stopper groove 302, and the holder 530 is fixed against the top to complete the storage of the holder 530. • Fig. 6 is an enlarged view of the fixing device of Fig. 4, clearly showing the coupling states of the fixing member 604, the switch 602, and the fixed spring 606 to help understanding. The design of the holder is housed inside the body of the display device, which not only visually maintains the original design of the display device, but also has a feeling of abruptness due to the holder, and also protects the holder. It will be apparent from the above-described preferred embodiments of the present invention that the application of the present invention has the following advantages. With the display device of the built-in file holding function of the present invention, it is convenient to view the reference file for efficient input of negative materials when using the computer information device. Moreover, since the holder is integrated into the display device and is fixed by the structurally simple fixing device, it is integrated with the display device when it is stored outside the display device, and the original overall contour perception is not impaired. The design stored in the display device body further maintains the original appearance of the display device, and must be externally fixed to the display device as compared with the conventional clamping device, thereby achieving a better aesthetic sense without a sudden sensation. When the display device with built-in file clamping function is used, in addition to manually rotating or pulling out the holder, an eject mechanism can also be used to automatically eject the holder, which is very convenient and fast on 12 1271325 (4). In addition, when the clamping function is not performed, the simple storage method of turning or pushing can be used to store the holder on the display device without a complicated disassembly procedure. Due to the function of quick storage, the holder can be conveniently stored, so the possibility of colliding and damaging the holder is reduced.
