Abstract:
A digital camera with a lens being automatically retractable and an automatic retraction method thereof are provided. After the digital camera is turned on, it can continuously capture images from the outside at a predetermined time interval, and convert the images into corresponding image characteristic values and then compare them. When the characteristic values of the current image differ from the previous one and reach a predetermined difference, the lens exposed outside is automatically retracted, so as to reduce damage to the lens due to falling or heavy shaking of the digital camera.
Abstract:
A digital camera structure is provided, which is used for preventing deviation of a preset optical axis caused by a reaction force generated when pressing a shutter button. A conductive element parallel to the optical axis and located on a pressing path of the shutter button is disposed in the digital camera. By pressing the shutter button, the conductive element is deformed and reset in a direction parallel to the preset optical axis. Thus, the vibration in a direction perpendicular to the optical axis is prevented, thereby not influencing the imaging quality.
Abstract:
A battery holding structure for an electronic device is provided, which includes a battery chamber having an opening, a fixing member and a cover. The fixing member has a cantilever extending from the battery chamber to the opening. The cantilever has a pressing portion at the opening, and the cover has a pushing portion corresponding to the pressing portion. When the cover covers the opening, the pushing portion presses against the pressing portion and fixes the battery installed in the battery chamber.
Abstract:
A key structure is provided, which includes a plurality of contact members and a control member. Each of the contact members has an elastic portion and a fixed portion, and the control member has a pressing portion and a combining portion. The control member is selectively combined with an appropriate contact member according to actual requirements in the electrical connection.
Abstract:
A two-in-one button structure includes a casing, a grounded plate, two signal plates, and two button bodies. The casing has two containing spaces and a plurality of guiding grooves respectively communicating with the two containing spaces. The grounded plate is contained in the two containing spaces. The two signal plates are separated from the grounded plate and are contained in the two containing spaces, respectively. The two button bodies are covering the two containing spaces, respectively. Each button body has a conductive element disposed on a bottom side thereof for allowing a conductive state to form between the grounded plate and a corresponding one of the two signal plates. Therefore, when one of the two button bodies is pressed, the grounded plate and the corresponding one of the two signal plates become conductive via the conductive element.
