Abstract
A technique reduces images unintended by the user captured with an electronic device having a camera function by unauthorized access or an accidental operation performed by the user. A blade open-close device includes a blade that opens or closes a lens aperture in a camera module, an actuator that opens or closes the blade, a drive that drives the actuator, and a switch that inputs an opening signal and a closing signal into the drive. The switch includes a mechanical switch operation member that generates the opening signal and the closing signal in response to a manual operation performed by a user. The drive is independent of a drive output from the camera module.
Claims19
A blade open-close device, comprising:
- a blade configured to open or close a lens aperture in a camera module;
- an actuator configured to open or close the blade;
- a drive configured to drive the actuator;
- and
- a switch configured to input an opening signal and a closing signal into the drive;
- and
- a substrate, wherein the drive and the switch are mounted on the substrate, and the substrate overlaps the actuator in a direction parallel to an optical axis of the camera module,
- wherein the switch includes a mechanical switch operation member configured to generate the opening signal and the closing signal in response to a manual operation performed by a user, and
- the drive is independent of a drive output from the camera module.
A blade open-close device, comprising:
- a blade configured to open or close a lens aperture in a camera module;
- an actuator configured to open or close the blade;
- a drive configured to drive the actuator;
- and
- a switch extending through a first opening in the camera module, wherein the switch is configured to input an opening signal and a closing signal into the drive;
- and
- a substrate, wherein the drive and the switch are mounted on the substrate, and the substrate overlaps the actuator in a direction parallel to an optical axis of the camera module,
- wherein the switch includes a mechanical switch operation member configured to generate the opening signal and the closing signal in response to a manual operation performed by a user, and
- the drive is independent of a drive output from the camera module.
