Abstract: A projector having a wheel module on its case is provided. The wheel module includes a wheel, an encoder, and a microswitch. When the wheel is pressed for a first time, the microswitch outputs a starting signal for turning on the projector. Then, the wheel is rotated for a first time, and the encoder outputs a menu signal for displaying the on screen display (OSD) menu on a screen. Then, when the wheel is rotated again, the encoder outputs a selection signal according to a rotation amount of the wheel for selecting a function or setting a parameter of the OSD menu. When the wheel is pressed again, the microswitch outputs a checking signal for executing a selected function, entering a sub-menu corresponding to the selected function, or storing the parameter.
