Document Type and Number:
WIPO Patent Application WO/2012/005047
Kind Code:
A1
Abstract:
A shutter frame (12) has a beam passage opening (20) which is, when the shutter frame (12) is disposed within an image forming device (50), disposed on the path of a beam emitted from a light scan device (88). A shutter member (14) is pivotably supported by the shutter frame (12) so as to selectively close the opening (20). The shutter member (14) is provided with shaft sections (146), a shutter (142), and connection sections (144). The shaft sections (146) are disposed outside the opposite ends of the opening of the shutter frame (12) in the longitudinal direction. The shutter (142) is plate-shaped and is configured so that the shutter (142) can close the entire area of the opening (20) of the shutter frame (12). The connection sections (144) are provided so as to rise from the shaft sections (146) and are configured so as to connect the shaft sections (146) and the shutter (142).
