<p>A tablet-form electronic device equipped with a screen cover. A host (1) is a tablet-shaped electronic device. A keyboard (4) is arranged on the screen cover (3). One end of a support rod (2) or of a support plate (22) is connected to the rear end of the screen cover (3), while the other end is connected to the host (1). When the host (1) is obliquely held on the screen cover (3) in a keyboard operation posture, either the support rod (2) or the support plate (22) serves as a supporting rod for the host (1). At where the bottom end of the host (1) is in contact with the screen cover (3), arranged is permanent magnet A (12), or, arranged is a hooking mechanism or a groove (12) or a retaining hook (13) for blocking a forward movement of the lower end of the host (1). This solves the problem of stability of the keyboard operation posture, thus the length of the support rod (2) or of the support plate (22) is reduced effectively, and increased structural neatness and compactness are allowed.</p> |
