This is the CURTAIN SHUTTER which is in the camera body just in front of the film plane.
A camera mechanism that allows light to expose film by moving curtains in front of the film plane.
a shutter that is positioned just in front of the film (Focal Plane). The exposure results from a slit traveling at a constant speed across the film - the actual shutter speed depending on the width of the slit. How the Shutter Works
One of the two main types of shutter and used universally in 35mm SLR cameras, positioned behind the lens and in fact slightly in front of the focal plane; the shutter consists of either cloth or metal blades. When the camera is fired a slit travels across the image either vertically or horizontally. The width and speed of the slit determines the duration of the exposure.

n. A shutter on or as close as possible to the focal plane. _______________________________________________________
A shutter in a Single-Lens Reflex that lies in front of the focal plane. The focal plane shutter is an electronic shutter that is used in modern cameras.
Cloth or metal band running close to the surface of the sensitive material. Exposure time is controlled by altering the width of gap in the band or its traverse speed.
A type of shutter mechanism that operates near the "focal plane", in other words, very close to where the lens focuses the image on the film. Typically these shutters are actually made of 2 curtains that travel very close to the film. By varying the interval between the curtains the amount of time that light is allowed to reach the film is controlled. Thus, a short interval of time produces a high (or "fast") shutter speed; a long interval of time produces a long (or "slow") shutter speed.
A shutter placed just off the surface of the focal plane. Typical shutter type for 35mm SLR cameras.
A camera shutter situated directly in front of the film, composed of an opaque curtain that contains a slit that moves directly across in front of the film, permitting light to strike the film.
shutter which lies just in front of the focal plane. Light sensitive film positioned at the focal plane is progressively exposed as the shutter blinds move across it.
