Abstract
A menu control device includes a casing and a roller module. The roller module is installed in the casing. The roller module includes a base, an elastic supporting arm, a scroll wheel, an encoder, a switch element and a microprocessor. The elastic supporting arm is connected with the base. The scroll wheel is pivotally coupled to the elastic supporting arm. The encoder is located beside the scroll wheel. The encoder generates an encoding signal in response to the rotation of the scroll wheel. When an external pressing force is applied to the scroll wheel, the elastic supporting arm is swung toward the switch element, and the switch element is triggered to generate a switching signal. The microprocessor performs an item browsing operation on a menu according to the encoding signal. The microprocessor performs an item selecting operation on the menu according to the switching signal.
