Aperture device, camera module with aperture device, and electronic apparatus

A camera module, comprising:

• a lens unit comprising a lens;
• a housing accommodating the lens;
• a power-receiving portion mounted on the housing and receiving electric power supply from outside;
• and
• an aperture device for setting an amount of light incident on the lens,
• wherein the aperture device comprises:
• a diaphragm plate comprising a shielding region for shielding the light incident on the lens;
• and
• a configuration-changing mechanism for changing a configuration of the diaphragm plate to an aperture position or a retracted position, wherein the aperture position is a position where the diaphragm plate is on the lens and a center of an aperture opening is located in a position corresponding to an optical axis of the lens, and the retracted position being a position where the diaphragm plate is retracted from the lens.

An electronic apparatus, comprising:

• a lens;
• and
• an aperture device for setting an amount of light incident on the lens,
• wherein the aperture device comprises:
• a diaphragm plate comprising a shielding region for shielding the light incident on the lens;
• and
• a configuration-changing mechanism for changing a configuration of the diaphragm plate to an aperture position or a retracted position, wherein the aperture position is a position where the diaphragm plate is on the lens and a center of an aperture opening is located in a position corresponding to an optical axis of the lens, and the retracted position is a position where the diaphragm plate is retracted from the lens.
