Abstract
A camera mechanism comprises a shutter blade movable to uncover and cover an exposure aperture; a primary spring connected to the shutter blade to normally move the shutter blade to cover the exposure aperture, but susceptible of becoming disconnected from the shutter blade, and a substitute spring connected to the shutter blade to alternatively move the shutter blade to cover the exposure aperture when the primary spring becomes disconnected from the shutter blade.
Claims11
A single camera for taking only one picture at a time, comprising:
- a single operation-performing device movable to perform a camera operation;
- a primary actuator moving said singe operation-performing device to perform the camera operation, but susceptible of mechanically failing so as to be unable to move said singe operation-performing device to perform the camera operation;
- and
- a substitute actuator operable to move said single operation-performing device to perform the camera operation only when said primary actuator is mechanically fails.
A single camera for taking only one picture at a time, comprising:
- a single operation-performing device movable to perform a camera operation;
- a primary actuator connected to said single operation-performing device to move said single operation-performing device to perform the camera operation, but susceptible of becoming disconnected from said singe operation-performing device so as to be unable to move said single operation-performing device to perform the camera operation;
- and
- a substitute actuator connected to said single operation-performing device, but operable to move said single operation-performing device in place of said primary actuator to perform the camera operation only when said primary actuator is disconnected from said single operation-performing device.
A camera mechanism comprising:
- an operation-performing device movable to perform a camera operation;
- a primary spring normally urging said operation-performing device to perform the camera operation, but susceptible of failing to move said operation-performing device;
- and
- a substitute spring alternatively urging said operation-performing device to perform the camera operation when said primary spring fails to move said operation-performing device.
A single camera for taking only one picture at a time, comprising:
- a single operation-performing device movable to perform a camera operation;
- primary means for moving said single operation-performing device to perform the camera operation, but susceptible of mechanically failing so as to be unable to move said singe operation-performing device to perform the camera operation;
- and
- substitute means operable to move said single operation-performing device to perform the camera operation only when said primary means mechanically fails.
A method of operating a camera mechanism, comprising:
- a primary spring connected to an operation-performing device moving the operation-performing device to perform a camera operation;
- and
- a substitute spring connected to the operation-performing device moving the operation-performing device to perform the camera operation only when the primary spring becomes disconnected from the operation-performing device.
A method of operating a camera mechanism, comprising:
- a primary spring, connected to a shutter blade, moving the shutter blade to cover an exposure aperture;
- and
- a substitute spring, connected to the shutter blade, moving the shutter blade to cover the exposure aperture only when the primary spring becomes disconnected from the shutter blade.
