Abstract
Abstract A device is provided for scanning the field of view of an optical instrument. The device includes a housing for connection to the optical instrument and a scanning means which has freedom to move in any direction to cover the area of an aperture in the housing which communicates with the optical instrument. Holding means releasably fix the position of the scanning means with relation to any given portion of the aperture and, therefore, the field of view. Interchangeable optical means may be mounted on the scanning means to increase the magnification of the area viewed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
129 words
Apparatus for scanning a field of view comprising a housing having a wall with a first aperture, a cover member spaced from the wall to provide an annular slot, a tubular member adapted to mount optical means thereon, the tubular member providing a second aperture smaller than the first aperture, a projection extending laterally from the tubular member positioned in the slot, the diameter of the slot being substantially greater than the lateral dimension of the projection to permit the tubular member to be both slideable and rotatable to adjust the position of the second aperture with respect to the first aperture, and holding means associated with the projection to releasably fix the position of the tubular member and thereby the second aperture with respect to the first aperture.
Claim 2
Dependent Claim
129 words
Apparatus for scanning a field of view comprising a housing having a wall with a first aperture, a cover member spaced from the wall to provide an annular slot, a tubular member adapted to mount optical means thereon, the tubular member providing a second aperture smaller than the first aperture, a projection extending laterally from the tubular member positioned in the slot, the diameter of the slot being substantially greater than the lateral dimension of the projection to permit the tubular member to be both slideable and rotatable to adjust the position of the second aperture with respect to the first aperture, and holding means associated with the projection to releasably fix the position of the tubular member and thereby the second aperture with respect to the first aperture.
Claim 3
Dependent Claim
24 words
Apparatus for scanning a field of view according to claim 1 wherein the projection extending laterally from the tubular member is an annular flange.
Claim 4
Dependent Claim
48 words
Apparatus for scanning a field of view according to claim 2 wherein the cover member has an opening providing a third aperture substantially larger in diameter than the diameter of the tubular member, the diameter of the third aperture being greater than the diameter of said first aperture.
Claim 5
Dependent Claim
25 words
Apparatus for scanning a field of view according to claim 3 further comprising means surrounding the first aperture for connecting the housing to optical apparatus.
Claim 6
Dependent Claim
25 words
Apparatus for scanning a field of view according to claim 4 further comprising means for centering the tubular member with respect to the first aperture.
Claim 7
Dependent Claim
56 words
Apparatus for scanning a field of view according to claim 2 wherein the holding means comprises spaced locking pins extending through the cover member having their ends in engagement with the annular flange, and a locking ring in threaded engagement with means provided by the cover member engageable with the opposite ends of the locking pins.
Claim 8
Dependent Claim
56 words
Apparatus for scanning a field of view according to claim 4 wherein the holding means comprises spaced locking pins extending through the cover member having their ends in engagement with the annular flange, and a locking ring in threaded engagement with means provided by the cover member engageable with the opposite ends of the locking pins.
