Abstract: An electronic apparatus for taking an image of an object comprises a lens for receiving the image of the object in the form of optical signals, and a converter for converting the optical signals from the lens into electrical signals the converter being adjustable in orientation with respect to the lens.

Abstract: A portable electronic device includes a main body for performing a function of the portable electronic device, a display unit removable or separable from the main body for displaying a result of the function performed by the main body, and a transmission line for electrically connecting the main body and the display unit such that the display unit can be separated from the main body without disconnecting the electrical connection between the display unit and the main body.

Abstract: Present invention is an optical fiber transfer apparatus which comprises two optical transfer facilities, two transfer connectors and a fiber cable, wherein each optical transfer facility comprises an optical transmitter and an optical receiver and is tied in with a transfer connectors and a fiber cable is between the two transfer connectors. The transfer connector comprises a coupler and an isolator, wherein the optical signal from the optical transmitter enters into terminal T of the isolator and is transferred to terminal C of the coupler that a one-way transmission channel is formed at the isolator. And the optical signal from terminal C of the coupler will be hindered by the isolator and be transferred to the optical receiver through terminal R of the coupler. Accordingly, by using only one fiber in the fiber cable, cost reduction, easy installation and a two-way transmission for optical signal can be achieved.
