Abstract

A projecting device is provided. The projecting device is adapted to assembling with an electronic device. The projecting device comprises a main body, a light emitting portion, a rotating portion, and an adjusting portion. The main body includes a first opening and a second opening. The light emitting portion is disposed in the main body, and transmits a light through the first opening. The rotating portion is disposed in the main body and connected with the light emitting portion. The adjusting portion is disposed in the second opening and connected with the rotating portion. The light emitting portion drives the rotating portion to rotate through the adjusting portion to adjust the angle of the light.

First claim

What is claimed is:

1. A projecting device, adapted to assembling with an electronic device, comprising:
a main body, having a first opening and a second opening;
a light emitting portion, disposed in the main body, and transmitting a light through the first opening;
a rotating portion, disposed in the main body, and connected with the light emitting portion;
an adjusting portion, disposed in the second opening, and connected with the rotating portion; and
a top cover covering the first opening;
wherein, the light emitting portion drives the rotating portion to rotate through the adjusting portion to adjust the angle of the light;
wherein a graphic element having a first proportion is disposed between the top cover and the light emitting portion, the light from the light emitting portion passes through the graphic element and the top cover and forms a projecting image having a second proportion on a target object, and the first proportion is different from the second proportion;
wherein an original pattern corresponding to the graphic element has a normal proportion, and a difference between the normal proportion and the second proportion is smaller than a difference between the normal proportion and the first proportion.

2. The projecting device according to claim 1 , wherein the main body includes a base, a support, and a casing, the base is connected with the support, and the casing encases the support outside.

3. The projecting device according to claim 2 , wherein the base is disposed on a desktop, an angle is formed between the light and a horizontal line parallel to the desktop, and the angle is range from 45 degrees to 135 degrees.

4. The projecting device according to claim 3 , wherein when the size of the angle is fixed, the light emitting portion is adjusted along a horizontal direction.

5. The projecting device according to claim 1 , wherein the top cover is made of transparent material.

6. An electronic device, comprising:
a projecting device, comprising:
a main body, having a first opening and a second opening;
a graphic element;
a light emitting portion, disposed in the main body, and transmitting a light through the graphic element to form a projecting image on a target object;
a rotating portion, disposed in the main body, and connected with the light emitting portion; and
an adjusting portion, disposed in the second opening, and connected with the rotating portion, wherein, the light emitting portion drives the rotating portion to rotate through the adjusting portion to adjust the angle of the light;

a detector, detecting a position information of the projecting image with respect to the main body; and
a controller, adjusting an image information of the graphic element according to the position information.

7. The electronic device according to claim 6 , wherein the projecting device further includes a transparent top cover covering the first opening.

8. The electronic device according to claim 6 , wherein the graphic element is an electronic dot pattern template, and the controller adjusts the image information of the electronic dot pattern template.
