Abstract: An express package collection locker capable of automatically calculating the portage fee of a package. The locker comprises a plurality of boxes for storing packages, a plurality of weight sensors incorporated in the boxes, respectively, and a plurality of push buttons for selecting regions from a map which correspond to possible destinations of the package. The locker further comprises a CRT display for displaying operating instructions, and a main controller. The main controller calculates the portage fee of a package placed in any one of the boxes, in accordance with the weight of the package measured by the weight sensor provided within the box, and the region destination of the package, which has been selected by operating the desired button. The portage, thus calculated, is displayed by the CRT display. The main controller locks the door of the box when the portage is duly paid into the locker, and then prints and issues a voucher.
