PROJECTOR
First Claim
1. A projector, comprising:
- a casing, having an opening;
a central processing unit, disposed in the casing, the central processing unit generating an on screen display menu in response to a menu signal, and the on screen display menu comprising a plurality of functions or a parameter;
a projection module, disposed in the casing and coupled to the central processing unit, and the projection module being capable of projecting the on screen display menu on a screen; and
a wheel module, disposed in the casing and coupled to the central processing unit, the wheel module comprising a wheel, an encoder and a microswitch, wherein a part of the wheel is exposed from the opening, the wheel for turning on the microswitch has a central shaft, and one end of the central shaft penetrates the encoder;
wherein 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 the menu signal for displaying the on screen display menu on the screen;
when the wheel is rotated again, the encoder outputs a selection signal according to a rotation amount of the wheel for selecting one of the functions or setting the parameter; and
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.

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.

3. A projector, comprising:
-
a casing, having an opening; a central processing unit, disposed in the casing, the central processing unit generating an on screen display menu in response to a menu signal, and the on screen display menu comprising a plurality of functions or a parameter; a projection module, disposed in the casing and coupled to the central processing unit, and the projection module being capable of projecting the on screen display menu on a screen; and a turning knob module, disposed in the casing and coupled to the central processing unit, the turning knob module comprising a turning knob, an rotary encoder and a microswitch, wherein the turning knob is exposed from the opening, and is capable of driving the rotary encoder to rotate, and the turning knob being used for turning on the microswitch; wherein when the turning knob is pressed for a first time, the microswitch outputs a starting signal for turning on the projector;
then, the turning knob is rotated for a first time, and the rotary encoder outputs the menu signal for displaying the on screen display menu on the screen;
when the turning knob is rotated again, the rotary encoder outputs a selection signal according to a rotation amount of the turning knob for selecting one of the functions or setting the parameter; and
when the turning knob 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. - View Dependent Claims (4, 5, 6)
