ABSTRACT:
An electronic scale electronically determines postage or shipping rates and displays also actual weight in chosen increments of items weighed by a platform atop an enclosure of the scale. A weight sensor provides an analog signal representing item weight. This signal is converted to a digital signal and provided to a computing circuit having a microprocessor for computing weight and rate signals corresponding to the digital signal. Separate weight and rate displays display total weight digitally and display also the actual cost of shipping or postage. An encoded rate selection device is readily and selectively usable with, and replaceable with respect to, the enclosure allowing the user to select a desired predetermined postage or shipping rate schedule, or structure. This device may be a rate selection card carried upon a front panel of the enclosure or a circuit board received within the enclosure. Detectors decode the rate selection device encoding for computing of weight and rate signals only according to this predetermined schedule.
