Abstract: A handheld electronic device including a first body, a second body, a flexible electrical connecting means and a cover is provided. The second body is slidely coupled to the first body. The flexible electrical connecting means is electrically connected between the first body and the second body and the cover is slidely coupled to the second body. The cover is located at a first position on the second body when the first body and the second body are in a stacked state. The cover shields the flexible electrical connecting means exposed due to the movement of the second body against the first body when the first body and the second body are in a spread state. Therefore, reliability and appearance of the handheld electronic device can be improved. In addition, available area on the handheld electronic device in the spread state can be increased, to provide higher design flexibility.

Abstract: A key structure of a portable electronic device is provided. The portable electronic device has a first operation mode and a second operation mode. The key structure comprises a key, a first light source, and a second light source. The first light source emits a first colored light in the first operation mode so that the key can display a first input symbol. The second light source emits a second colored light in the first operation mode so that the key can display a second input symbol. As a result, users who operate portable electronic devices with the aforementioned key structure can easily recognize the different kinds of input symbols corresponding to different input methods in different operation modes.

Abstract: A handheld electronic device comprising a main body, a stylus and a non-contact sensor is provided. The main body has a containing slot, and the stylus having a sensing region is suitable for being inserted into the containing slot. The non-contact sensor is disposed beside the containing slot. The non-contact sensor outputs a sensing signal for identifying the position of the stylus when the stylus moves in the containing slot and the sensing region of the stylus passes the non-contact sensor. By detecting the position of the stylus in a non-contact manner, the reliability and the lifetime of the handheld electronic device are improved, and a higher sensing precision is also provided.

Abstract: A handheld electronic device including a body, a cover, an engaging assembly, and a releasing member is provided. The cover is disposed on the body and has a hole. The engaging assembly is movably disposed between the body and the cover to engage the cover on the body. The releasing member is disposed on the body and exposed by the hole of the cover. The releasing member is suitable for leaning against the engaging assembly and driving the same from an engaging position to a releasing position so as to release the cover.

Abstract: A connector and an electronic apparatus and a combination comprising the connector for first and second joints are disclosed. The connector includes a base, a plurality of first pins, and a plurality of second pins. The base has a first and a second connecting surface. The first pins are disposed on the first connecting surface and the quantity of the first pins is the same as the pin quantity of the first joint. In addition, the second pins are disposed on the second connecting surface and the total quantity of the second pins and the first pins is the same as the pin quantity of the second joint. The base may include two convex parts and a concave part. The first connecting surface and the second connecting surface are disposed on surfaces of the two convex parts respectively. The concave part accommodates the two convex parts.

Abstract: A connector for connecting a host and a peripheral device is disclosed. The connector includes N pin groups and each of the N pin groups has different pin length, wherein N is a positive integer and is greater than or equal to 3. The first pin group consists of ground pins and has the longest pin length.

Abstract: A compatible connector for first and second joints having different pin quantities is disclosed. The connector includes a base, at least one first pin, and at least one second pin. The base includes a first connecting surface and a second connecting surface. The first pins are disposed on the first connecting surface and the quantity of the first pins is the same as the pin quantity of the first joint. In addition, the second pins are disposed on the second connecting surface and the total quantity of the second pins and the first pins is the same as the pin quantity of the second joint.
