Abstract
An apparatus for preventing mirror bounce in a camera includes a mirror member rotatable in reciprocation between a viewing position and a photographing position. A mirror receiving member receives a kinetic energy of the mirror member by making a predetermined motion when a collision of the mirror member takes place and, at the same time, position-regulates the mirror member in the viewing position. A moment of inertia of the mirror receiving member and/or the mirror member is set so that a bounce time after the collision of the mirror member is shorter by 15% or above than a bounce time when fixing the mirror receiving member.
