DETAILED DESCRIPTION

Referring toFIG. 1, a portable electronic device10may be a notebook computer. The portable electronic device10includes a main body100, a display200pivotally connected to the main body100, a writing tablet300, two connecting rods400rotatably connecting the writing tablet300with the main body100. The main body100accommodates core components of the portable electronic device10, such as integrated circuits (ICs), integrated processing chips, etc.

Referring toFIGS. 2 to 4, both of the main body100and the display200may be rectangular. The main body100has a top wall105, a front wall107, a rear wall109, and two first sidewalls110. The two first sidewalls110are on opposite sides of the main body100and connect between the front wall107and the rear wall109.

The display200is attached to the rear wall109and rotatable with respect to the main body100, thus the display200is changeable between a first state and a second state. In the first state, the display200covers the main body100and contacts the top wall105. In the second state, the display200is rotated away from the top wall105.

The main body100defines two shaft holes102in the two first sidewalls110, respectively. The shaft holes102are adjacent to the rear wall109correspondingly. A jack104is disposed in the top wall105and adjacent to the front wall107.

The display200has a lower wall208and two second sidewalls210on opposite sides of the200connected with the lower wall208. The lower wall208is adjacent to the rear wall109. Two protrusions202are arranged on the second sidewalls210, respectively. The two protrusions202extend from an end of each of the second sidewalls210away from the lower wall208. The display200defines a receiving portion204in one end of the display200away from the lower wall208. Two first magnetic bodies206are arranged on another end of the display200adjacent to the lower wall208.

The writing tablet300may be have a similar shape with the main body100. For example, the writing tablet300is a rectangular sheet. The writing tablet300includes two surfaces, i.e., a first surface310, and a second surface320on opposite sides of the300. The first surface310acts as an input surface for receiving input operations.

Two baffles370protrude perpendicularly from the writing tablet300away from the first surface310. The two baffles370are located at one side of the writing tablet300. Each baffle370defines a through hole302. A plug304corresponding to the jack104is arranged on the second surface320.

Two second magnetic bodies600may have a similar shape with the first magnetic bodies206. The two second magnetic bodies600are located at another side of the writing tablet300opposite to the two baffles370.

The lengths of the connecting rods400are a little longer than those of the first sidewall110and the second sidewall210. A through hole402and a shaft hole404are defined on opposite ends of each connecting rod400.

In assembly, the shafts500are passed through the through holes402and the shaft holes102correspondingly to pivotally connected the two connecting rods400with the main body100. Then the shafts550are passed through the two through holes302and inserted into the shaft holes404correspondingly, thus the writing tablet300pivotally connects with the two connecting rods400to selectively locate in a first position, a second position and a third position. The two connecting rods400are between the two baffles370.

When the writing tablet300locates at a first position (referring toFIG. 1), the writing tablet300is between the main body100and the display200. The writing tablet300covers the main body100, and the second surface320faces the main body100. The first side walls110are between the two connecting rods400and adjacent to the two connecting rods400correspondingly. The plug304is inserted into the jack104to electrically connect the writing tablet300with the main body100, thus the writing tablet300can generate input signals based on received input operations and transmit the input signals to the main body100. The writing tablet300has similarity with conventional writing implements, thus the portable electronic device10with the writing tablet300is suited to be used for character inputs. In addition, the size of the writing tablet300is not limited by size of the main body100, and the writing tablet300can be designed in sizes satisfying various requirements of users.

When the writing tablet300locates at a second position (referring toFIGS. 6 and 7), The display200is between the writing tablet300and the main body100.
