摘要
An electronic whiteboard includes a projection unit, an adjusting mechanism, and a projection screen. The adjusting mechanism includes a fixing base, a rotary plate, and a first screw. The fixing base is adapted to be fixed to a fixing object. The rotary plate is pivotally connected to the fixing base, and is ball jointed to the projection unit. The first screw is locked on the rotary plate, and is ball jointed to the projection unit. The first screw drives the projection unit to rotate relatively to the rotary plate along a first axis when the first screw is rotated. The projection screen is adapted to be fixed to the fixing object. The projection unit is capable of projecting an image beam onto the projection screen.
