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 security device includes a holder, a cover and at least one flexible plate. The holder contains the battery. The cover slips to set on the holder and has at least one raised lump to press the flexible plate. The flexible plate is set between the holder and the cover and has at least one elastic arm. The elastic arm has a stressed portion and at least one contact portion. When the cover slips to set on the holder, the raised lump presses down the stressed portion to increase the pressure of the elastic arm for avoiding power failure caused of the battery be shook. Further the device to fix a battery does not increase the force of setting the cover and not need any other component. To sum up, the device to fix a battery of present invention has low cost and friendly use.

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 button is provided for pressing against a metal dome to trigger a signal. The key button structure includes a button cap and a button stem. One tip end of the button stem is in a shape of spherical camber which is in point contact with the metal dome, so that the button stem, when being pressed, is within an effective pressing area of the metal dome to prevent the metal from being permanently deformed and damaged.

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 fixing boss structure disposed on a housing having a plurality of blind holes is provided, which includes a post and a pressing part that disposed at one end of the post. A combining hole is opened inside the post, and the outside diameter of the pressing part is larger than the inside diameter of the blind hole, so as to force the pressing part to be pressed and fixed inside the blind hole.

Abstract: A metal pad of mode dial and a manufacturing method thereof, wherein the metal pad is disposed on a substrate and the metal pad comprises at least one metal base pad and at least one conductive foil layer. The conductive foil layer is fixed on the metal base pad in an attached way instead of plating with gold on the metal base pad to reduce production costs so as to prevent oxidization of the metal base pad.

Abstract: A rotation sensor comprising a Y-shaped strip and a conducting strip is disposed in a digital imaging device. The conducting strip is disposed below the Y-shaped strip. The Y-shaped strip has two sensing arms and a fixed arm. A metal piece is disposed on each of the two sensing arms. When the sensing arm hangs down due to the weight of the metal piece to touch the conducting strip, the Y-shaped strip and the conducting strip will form a closed circuit and send out a signal. Whether the digital imaging device is rotated is determined based on this signal. Whether the device body is horizontal or vertical can thus be accurately and quickly determined. Moreover, because the detection is accomplished through gentle deformation or rotation of the sensing arms, there will be no noise during the detection process.

Abstract: A model dial mechanism comprises a circuit board provided with a mode layout circuit, several dome elements, and a mode dial button. The dome elements are provided at intervals on the circuit board to correspond to the mode layout circuit. The mode dial button is rotatably provided on the circuit board, so that the dome elements are electrically connected to the corresponding mode layout circuit. Make use of this, the mode dial mechanism can provide a well-contact effect.

Abstract: An electrical connector structure is provided. The electrical connector structure is applicable in an electronic device having a printed circuit board (PCB), and is electrically connected with the PCB via a flexible flat cable (FFC). The electrical connector structure includes a plurality of electrical terminals disposed on the PCB, and a sleeve lid disposed at the position corresponding to the electrical terminals. The sleeve lid is formed with an opening. The FFC extends into the opening to contact the electrical terminals. A blade spring disposed on the surface of the sleeve lid is used to press the FFC, making its contact with the electrical terminals compact.

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.

Abstract: A two-stage button structure includes: a silver paste PCB, a metal dome, a film, a flexible contact body, and a button body. When the button body is pressed to a first stage, the pair of conductive blocks of the flexible contact body respectively passes through the pair of through holes of the film to respectively electrically contact the first and the second conductive areas in order to generate a first stage signal. When the button body is pressed to a second stage, the metal dome is pressed via the contact pin to touch the third conductive area and the pair of conductive blocks respectively electrically contact the first and the second conductive areas at the same time so that the second and the third conductive areas electrically connect with each other to generate a second stage signal.

Abstract: A lamp receptacle including a receptacle body to hold a lamp bulb, a mounting base revolvably fastened to the receptacle body by a bolt, two contact blades fixed to the mounting base for connection to the power supply outlet, a first metal contact plate and second metal contact plate respectively fastened to the receptacle body and disposed in contact with the contact blades, and a third metal contact plate controlled by an ON/OFF switch on the receptacle body to connect/disconnect the first metal contact plate and the second metal contact plate.
