Abstract
A mirror device for a camera having a first mirror arrangement pivotable from a finder-viewing position to an exposure or retracted position, and a second mirror arrangement pivotable with its fulcrum formed on the first mirror arrangement. While the first mirror arrangement moves pivotally from the finder-viewing position to the exposure or retracted position, the second mirror arrangement is pivotally moved from a resting position in contact with the first mirror arrangement as it is open, through a sliding movement on a camming surface of the camera body to a closing position for a half-mirrored portion of the first arrangement.
