Abstract
An optical scanner with an improved chassis locking mechanism. The improved chassis locking mechanism includes a chassis, a latch disk, a scanner case and a cover. The latch disk has a shaft for turnably resting on a rack of the scanner case and being held from falling off the rack by a pair of brackets of the cover. The latch disk also has a limiting bulge for limiting the turning angle of the latch disk and a plurality of positioning notches formed on the circumference thereof. The latch disk further has a locking slot for receiving or locking a strut ofthe chassis. By turning the latch disk to a predetermined angle, one of the positioning notches will be engaged with a positioning bulge on the scanner case. The locking slot of the latch disk will either allow the strut to move freely or lock the strut from moving so that the chassis can be held stationary during transportation to reduce damage that might otherwise occur.
