Portable electronic device with multiple projecting functions
View Patent ↗A portable electronic device with multiple projecting functions is provided. The portable electronic device includes a main body, a projecting module, and a switching mechanism. The projecting module is disposed within the main body for generating an image beam. The switching mechanism is movably disposed on the main body. When the switching mechanism is located at a first position, the image beam is projected along a first projecting path, and the portable electronic device is in a first operating mode. When the switching mechanism is located at a second position, the image beam is projected along a second projecting path, and the portable electronic device is in a second operating mode.
1. A portable electronic device with multiple projecting functions, the portable electronic device comprising:
a main body having a first surface and a second surface;
a first window disposed on the first surface of the main body;
a second window disposed on the second surface of the main body;
a projecting module disposed within the main body for generating an image beam; and
a switching mechanism movably disposed on the main body, wherein when the switching mechanism is located at a first position, the image beam is projected along a first projecting path, wherein when the switching mechanism is located at a second position, the image beam is projected along a second projecting path,
wherein the switching mechanism comprises a first shell surface, a second shell surface, a third window, and a reflective mirror, wherein the third window is disposed on the second shell surface, wherein when the switching mechanism is located at the second position, the first window is covered by the first shell surface of the switching mechanism such that the reflective mirror is aligned with the first window, and the second window is covered by the second shell surface of the switching mechanism such that the third window is aligned with the second window.
2. The portable electronic device as claimed in claim 1 , wherein the reflective mirror is a plane mirror.
3. The portable electronic device as claimed in claim 1 , wherein a projecting zone of the image beam along the second projecting path is expanded or shrunken by changing a curvature of the reflective mirror.
4. The portable electronic device as claimed in claim 1 , wherein the reflective mirror is a spherical mirror, and the spherical mirror has a positive curvature or a negative curvature.
5. The portable electronic device as claimed in claim 1 , wherein the reflective mirror is a non-spherical mirror.
6. A portable electronic device with multiple projecting functions, the portable electronic device comprising:
a main body;
a projecting module disposed within the main body for generating an image beam; and
a reflective mirror movably disposed on the main body,
wherein the image beam has a first projecting path without reflecting by the reflective mirror for use as an ordinary image projecting function, and a second projecting path with reflecting by the reflective mirror for use as a virtual keyboard creating function,
wherein the reflective mirror is a spherical mirror, and the spherical mirror has a positive curvature or a negative curvature.
7. The portable electronic device as claimed in claim 6 , wherein the reflective mirror is at a first position when the image beam has the first projecting path, and the reflective mirror is at a second position when the image beam has the second projecting path.
8. The portable electronic device as claimed in claim 6 , wherein the image beam is selected to have alternatively the first projecting path and the second projecting path.
