Abstract
A postal charge processing system, which comprises a postal charge calculator for calculating the postal charge of a postal parcel from weight data corresponding to the weight of said postal parcel and post condition data concerning post conditions for the postal parcel including the way of mail and region of destination. A memory, numeral keys which are operated when writing a desired fee data in said memory, a clear key for clearing the data in the memory, a meter stanp issue key operated when issuing a meter stamp corresponding to the data in the memory and a meter stamp issuing unit including a data processing unit for controlling the memory in accordance with the operative state of the afore-said various keys, is provided. The data processing unit is set to a clear key lock state at the time when a predetermined bit of charge data calculated by the calculator is transferred therefrom to the memory, and in this state it nullifies key-in data produced with the operation of the clear key.
