The friction member includes at least two carbon nanotube composite layers stacked on each other, each carbon nanotube composite layer includes a polymer and a carbon nanotube structure including a number of carbon nanotubes substantially oriented along a same direction. An angle defined by the carbon nanotubes oriented along the same direction in adjacent carbon nanotube composite layers ranges from greater than 0 degrees, and less than or equal to 90 degrees. The camera shutter using the friction member is also provided. The camera shutter includes a brake mechanism and a drive mechanism including a blade driving lever having a moving path. The brake mechanism includes two abovementioned friction members and a brake lever clamped between the two friction members. The brake lever is located at a termination of the moving path to brake the blade driving lever.

摘要： When a hold member rotates on a shaft counterclockwise in the set operation, pressing parts of a pressing member which is fitted on top end of the hold member press pressed parts of iron piece members to rotate a lock-releasing member for a first blade and a lock-releasing member for a rear blade so that the iron piece members are made to come into contact with iron-core members of electromagnets, while an engagement pin presses an arm of a connection spring to rotate a restraining member clockwise so that a restraining part of the restraining member moves into the trajectory of the movement of a restrained part of the lock-releasing member for the rear blade. When the coils of the electromagnets are not electrified and the hold member rotates clockwise, the lock-releasing member for the front blade presses a front blade locking member to make it possible to perform an open operation of the front blade, while the lock-releasing member for the rear blade cannot press a rear blade locking member because the lock-releasing member for the rear blade is restrained by the restraining member. As a result, an exposure aperture is fully opened, and it becomes possible to perform observation with electronic finder.
