ABSTRACT:
Apparatus for calculating the price of a measured length of material comprising a sensor for detecting the movement in either of two directions of a material having a length to be measured and a price per unit length. The unit price of the material is entered into the apparatus and a binary value related thereto is derived. Logic components responsive to the sensor determine the direction of material movement and provide a first signal representative of the distance the material moves in a forward direction and a second signal representative of the distance the material moves in a reverse direction. An output signal representing the total price of the measured length of material is provided in response to the first and second signals and the binary value derived from the unit price. A display responds to the output signal to indicate the total price of the measured length of material.
