Abstract: A riser card rotating module is disposed adjacent to an expansion slot and includes a guide plate, a fixing plate, a riser card, a first pivot member and a second pivot member. The guide plate has a first guide rail parallel to a plug-unplug direction of the expansion slot and a second guide rail perpendicular to the plug-unplug direction of the expansion slot, wherein the first guide rail and the second guide rail communicate with each other to form a T-shape. The riser card is fixed on the fixing plate and has an electric connector. An end of the first pivot member is fixed on the fixing plate. Another end of the first pivot member is movably disposed on the guide plate. An end of the second pivot member is fixed on the fixing plate. Another end of the second pivot member is movably disposed on the guide plate.

Abstract: A test device includes a base, a locating component installed on the base, a platform disposed on the base, an operating component, a driving component installed on the platform, at least one light emitting component, at least one sensing component and a control unit. The driving component is for driving the operating component. The at least one light emitting component is disposed on at least one track of the platform for emitting light. The at least one sensing component is for sensing the light emitted from the at least one light emitting component and reflected from the workpiece. The control unit determines whether to control the driving component to drive the operating component to move to the workpiece according a sensing result of the at least one sensing component sensing the light emitted from the at least one light emitting component and reflected from the workpiece.
