Abstract
A camera 14 has a shutter 42 that is reciprocally movable by a motor 54 that is in positive engagement with the shutter 42. The motor 54 provides harmonic motion to the shutter 42 between its open and closed positions. A second motor 78 advances the film within the camera body. Both motors are connected to electronic brakes 104,118 to stop the motors when they are deactuated. The shutter has a mirror 50 mounted therein to provide a viewing of the image beam by the lens 36 through an eyepiece 122 when the shutter 42 is closed.
