Claims

[Claims for Utility Model Registration] A shutter device for an electronic camera that captures an image using an image sensor that generates an electrical signal according to the amount of incident light, the shutter device comprising a rotating disk, the rotating disk being connected to the image sensor. In front of the imaging plane,
It is arranged at a position where the extension line of the central axis of rotation does not intersect the imaging plane, and its size is sufficient to block light entering the imaging plane from the front; slits are formed radially with respect to the rotation center axis, and are capable of transmitting the incident light to the imaging surface;
- further comprising: a driving means for rotating the rotating disk; a speed setting means for giving the driving means a speed at which the rotating disk should be rotated; and a means for detecting the speed of the rotating disk; and means for reading out the charge generated by exposure to light incident on the imaging surface through the slit in response to a match between a set value of the setting means and a detected value of the detection means. Camera shutter device.
