Abstract: A dock includes a base, a fixing switch, a release component, a connector, and a connection component. When an electronic device is mounted on the base, the release component must be pressed in order for the fixing switch to be operable, allowing the connection component to drive the connector to connect with the electronic device. When no electronic device is mounted on the base, the connector is received in the base to protect the connector against damage while the dock is being carried around. That the release component must be pressed in order for the fixing switch to be movable protects the connector against damage in a situation where, while the dock is being carried around, the fixing switch is inadvertently pushed, causing the connector to protrude from the dock.

Abstract: A dock includes a base, a pivot axis piece, a plate member, a connector and at least one elastic element. The base includes an upper case having a pressing hole and a connecting hole. The pivot axis piece is disposed on the upper case and the plate is pivotally connected to the upper case by the pivot axis piece. A first end of a main plate of the plate member has a pressing element and corresponding to the pressing hole. The connector is disposed at a second end of the main plate relative to the pressing element and corresponding to the connecting hole. The elastic element is connected between the upper case and the main plate. The elastic element makes the second end move away the upper case and lets the connector receive in the connecting hole.

Abstract: A handle including at least one fixing portion, a handheld portion and at least one rotating module is provided. The fixing portion is fixed at a side of a body of an electronic device. The handheld portion is pivotally disposed at the fixing portion. The rotating module includes a ratchet and a positioning ball. The ratchet has a plurality of differences, and the ratchet passes through a pivotal end of the handheld portion and fixes to the fixing portion, and the positioning ball is fixed to the pivotal end and corresponding to the ratchet. The positioning ball moves along the differences of the ratchet when the handheld portion rotates relative to the fixing portion, and the handheld portion is positioned after rotating relative to the fixing portion through the ratchet to a first position or a second position. An electronic device using the handle aforementioned is also provided.

An electronic device using the handlebar aforementioned is also provided.

Abstract: An electronic device comprises an outer case, a wireless card reader and a signal processing device. The outer case comprises a door and a metal wall. The metal wall is disposed on a lateral side of the outer case and has an opening. The door is disposed on the metal wall and capable of covering the opening. The wireless card reader is inside the door and capable of transmitting wireless signals. The signal processing device has a case, a data storage device and a safety mechanism. The signal processing device is inside the outer case and is electrically connected to the wireless card reader. The signal processing device is capable of processing the data of wireless signals from the wireless card reader. When the case is dissembled, the safety mechanism destroys at least part of the data stored in the data storage device.

Abstract: A waterproof assembly for an electronic device includes a watertight door and a case. The watertight door includes a cover, a water absorbing ring, and a water blocking ring. The cover is provided for being disposed into an opening of the case. The water absorbing ring and the water blocking ring are disposed between an outer peripheral surface of the cover and an inner peripheral surface defining the opening. The water absorbing ring includes deformable material and water absorbent, such that the water absorbing ring expands by absorbing water and contacts the inner and outer peripheral surfaces. The water blocking ring is normally compressed and contacts the inner and outer peripheral surfaces. When water penetrating occurs, the water block ring blocks water preliminarily, and then the water absorbing ring block blocks fully water after completely expanding.
