Image pickup device and focal plane shutter

摘要

An image pickup device includes: an image pickup element; a control portion artificially driving an electronic leading blade by resetting stored charges of the image pickup element in a predetermined direction at every pixel line; and a focal plane shutter includes a board including an opening exposing the image pickup element, a mechanical trailing blade capable of opening and closing the opening, a trailing blade drive lever driving the trailing blade, an actuator actuating the trailing blade drive lever, a shading member capable of opening and closing at least a part of the opening, a shading member drive lever driving the shading member, a connection member provided on the shading member drive lever, and a biasing member biasing the shading member drive lever such that the shading member recedes from the opening.

1. An image pickup device comprising:
an image pickup element; a control portion artificially driving an electronic leading blade by resetting stored charges of the image pickup element: in a predetermined direction at every pixel line; and a focal plane shutter including:
a board including an opening exposing the image pickup element;a mechanical trailing blade capable of opening and closing the opening;trailing blade drive lever driving the trailing blade;an actuator actuating the trailing blade drive lever;a shading member capable of opening and closing at least a part of the opening;a shading member drive lever driving the shading member;a connection member provided in the shading member drive lever; anda biasing member biasing the shading member drive lever such that the shading member recedes from the opening; wherein: the trailing blade drive lever and the connection member are brought to a connected state of being connected to each other, in a in where the trailing blade closes the opening and the shading member recedes from the opening; when the trailing blade drive lever moves such that the trailing blade recedes from the opening in the connected state, the shading member drive lever moves such that the shading member travels to the opening in response to the trailing blade drive lever with maintaining a closed state of the opening; the connected state is released while the trailing blade drive lever moves such that the trailing blade recedes from the opening, and the shading member drive lever is moved by a biasing force of the biasing member such that the shading member recedes from the opening; and the control portion reads out image data from the image pickup element in the closed state.
