  • Pop-up flash unit for camera
    Patent number: 7505682
    Abstract: A pop-up flash unit (2) for a camera includes a mounting seat (30) disposed in the camera body, a flash member (20) rotatably mounted on the mounting seat between a projected position for operating and a retracted position for storage, a driving device (40) substantially disposed in the camera body for permitting movement of the flash member from the retracted position to the projected position, a pair of first torsion members (34, 35) for providing a resilient restoring force to the flash member to thereby permit movement of the flash member from the retracted position to the projected position, and a second torsion member (45) for reliably retaining the flash member in the retracted position. The flash member is retained in its retracted position via a latching engagement with the driving device.
