Electronic device with an adjustable back-supporting plate

摘要

An electronic device includes a housing that is formed with two fixed positioning members, and a back-supporting plate that is movable forcibly on an upright housing portion of the housing to move two tongues of two movable members along two annular guide slots in the positioning members. Each of the annular guide slots has a plurality of positioning slot portions. Each of the tongues of the movable members is limited to move within a corresponding one of the annular guide slots along a single direction, and is biased into a selected one of the positioning slot portions of the corresponding one of the annular guide slots. As such, the inclination angle of an upright housing portion of the housing relative to a horizontal support surface can be adjusted.
