Abstract
Abstract The present invention relating to a feeder adapted to be used with a scanner for feeding for the scanner an article comprises a shell adapted to mount therewith the scanner, a driving device for feeding for the scanner the article, an adjusting device contained in the shell to adjust a height of a passage through which the article can pass to be scanned by the scanner according to a thickness of the article, and a floating box contained in the shell and mounting therein the driving device. The present invention mounts the motor, the driving device and the group of gears together in a floating box which further cooperates with a shell to form the present feeder has at least the following advantages that a performance test can be proceeded before the whole feeder is set up completely, that because the floating box and the shell are separately manufactured, the whole feeder structure need not be scrapped in case of a little defect in each of the two parts, and that the floating box can cost-effectively cooperate with different kinds of shells favored by different countries.
