Referring to fig. 11 and 12, a difference between the electronic device 100 according to the second embodiment of the present application and the first embodiment is that a position of the arc-shaped guide rail 40 is different. Specifically, fig. 11 is a front view of the connection structure of the casing 20 and the sliding member 30, fig. 12 is a cross-sectional view B-B, a groove 40a is formed on one side of the rear cover plate 24 facing the display screen 10, the arc-shaped guide rail 40 is disposed on the rear cover plate 24, and the arc-shaped guide rail 40 forms a side wall of the groove 40a, so that when the sliding member 30 is accommodated in the front projection range of the display screen 10 in the casing 20, the sliding member 30 is accommodated in the groove 40 a. In one embodiment, the thickness of the slider 30 is the same as the depth of the groove 40a, and the slider 30 slides on the back cover plate 24. The sliding member 30 and the arc-shaped guide rail 40 do not occupy the space of the middle frame 22, and there is sufficient space in the middle frame 22 for arranging other electronic devices, which is beneficial to the arrangement of the devices in the electronic apparatus 100.
