Abstract:
A shutter apparatus includes a shutter base plate having an opening, a light shield movable between a closed state for closing the opening and an open state for opening the opening, a cam member rotatable in a first angle range, a second angle range, and a third angle range between the first angle range and the second angle range, the cam member that rotates in the third angle range rotating the light shield, a motor configured to drive the cam member, a forcing member configured to force the cam member so as to rotate the cam member from the first angle range to the third angle range, and a restricting member configured to restrict the forcing member from forcing the cam member in at least part of the first angle range.

Claim (Index 13):
An image capturing apparatus comprising a shutter apparatus and an image sensor configured to photoelectrically convert an optical image formed via an image capturing optical system,\n wherein a shutter apparatus includes: a shutter base plate having an opening: a light shield movable between a closed state for closing the opening and an open state for opening the opening; a motor; a drive member that includes a cam engagement pin and is rotatable in connection with the light shield; a cam member engaged with the cam engagement pin and rotatable in a first angle range, a second angle range, and a third angle range between the first angle range and the second angle range; a forcing member configured to force the cam member so as to rotate the cam member from the first angle range and the third angle range to the second angle range; and a transmission member connected to the cam member while the forcing member forces the cam member, the transmission member including a first area in which the transmission member transmits a force from the forcing member to a rotating direction of the cam member, and a second area in which the transmission member is held by the cam member without transmitting the force from the forcing member to the rotating direction of the cam member, wherein the first angle range is a range for moving the cam member without moving the light shield, the second angle range is a range for moving the cam member between the closed state and the open state of the light shield, and the third range is a range different from the first angle range and configured to move the cam member without moving the light shield.
