Abstract

An electronic postal scale for computing a postal charge in correspondence with complicated rates and additional services is disclosed. The electronic postal scale is basically constituted by a scale portion, an operating portion provided with preset keys, a first memory, a second memory, a third memory, and a control portion having reloading function. The scale portion measures a weight of a package so as to obtain weight data. The preset keys are used for reading out charge information concerning the package such as postal rates corresponding to destinations, service charges corresponding to postal kinds and other required information. Look up numbers are assigned corresponding to the preset keys. The first memory stores the charge information, and the second memory stores relations between the charge information and the look up numbers, and the third memory stores relations between the look up numbers and the preset keys. The reloading function changes contents of data stored in the second and third memory based on an operation of the operating portion. Furthermore, the control portion reads out the desirable charge information assigned to depressed preset key so as to calculate the postal charge of the package based on the weight data and the desirable charge information.
