摘要： A field-of-view frame switching device has a rectangular fixed field-of-view frame and a plurality of light-shielding members for covering portions of the rectangular fixed field-of-view frame so as to vary the size of the actual field-of-view frame. The light-shielding members are composed of a first pair of oppositely arranged light-shielding members and a second pair of oppositely arranged light-shielding members. The field-of-view frame switching device also has a coupling member for coupling the light-shielding members together in such relation that, when the first pair of light-shielding members are positioned closer to each other to narrow the actual field-of-view frame, the second pair of light-shielding members are positioned wide apart from each other and that, when the first pair of light-shielding members are positioned wide apart from each other, the second pair of light-shielding members are positioned closer to each other to narrow the actual field-of-view frame. The field-of-view frame switching device further has a moving member for moving at least a part of the light-shielding members in a direction substantially parallel to one side of the rectangular fixed field-of-view frame.

摘要： A camera has an AE sensor 10 and a display member 32 disposed in the vicinity of the focusing screen 4, and a field frame switcher having a light interrupting wing capable of changing a field frame. The light-interrupting wing crosses and interrupts a predetermined luminous flux path used for obtaining information necessary for photographing while the field frame is changed. The light-interrupting wing is disposed close to the predetermined luminous flux path to reduce the space needed to house the structure.
