A light-shielding door is configured between an upper component and a lower component of a top plate of a monitor hood. The door is capable of moving to open or to close at an opening of the top plate along a direction. The door includes a groove and the upper/lower component includes a track corresponding to the groove for allowing the door to move steadily. A rib is configured between the two components and adjacent to the door for preventing the door from derailing. The door further includes an indentation at the bottom of a handle at the front end. When the door closes, the indentation matches closely to the edge of the opening, providing perfect light shielding solution for the monitor hood.
