An adjustment device includes a base, a ratchet wheel assembly and a fixing rod. The base includes an accommodating groove and ratchet teeth. The ratchet wheel assembly is rotatably accommodated in the accommodating groove and includes a body, an elastic arm, and a pawl. The elastic arm includes a first connecting segment connected to the body and a second connecting segment connected to the pawl. The pawl may engage with one of the ratchet teeth. The fixing rod movably extends between the body and the elastic arm. When the fixing rod is arranged between the second connecting segment and the body, the pawl is fixed to the ratchet teeth, so that the ratchet wheel assembly is positioned on the base. When the fixing rod is arranged between the first connecting segment and the body, the ratchet wheel assembly may rotate relative to the base.

Adjustment device switchable between a rotatable state or a locked state

This invention discloses a portable computer capable of performing a digital photo frame function under a main-power-off state. The portable computer includes a base, a display device, an image capturing device, an image capturing switch, and a processor. The display device includes a frame pivotally connected to the base. The image capturing device and the image capturing switch are disposed at the frame. The image capturing switch is operated to output a first request signal to the processor. In response to the first request signal, the processor drive the image capturing device to capture a first image under the main-power-off state, and the processor instantly displays the first image on the display device under the main-power-off state.
