An improved price increment computer is disclosed that is used in a price computer for gasoline or fuel dispensing pumps wherein a blend of gasolines is dispensed. The improved price increment computer includes an input shaft that rotates in response to the total volume of blended fluid being dispensed and an output shaft that rotates at speeds proportional to the speed of the input shaft. An idler mechanism is provided that selectively and operably connects portions of the input and output shafts to provide the desired ratio of rotation therebetween. A selector mechanism that is rotated by the operator of the dispenser includes a plurality of cams, each of which engages a preselected portion of the idler mechanism to provide the desired output rotation depending on the price of the blend selected. The improved price increment computer is constructed so that the selector mechanism can be quickly and easily removed from the price increment computer to provide for the insertion, removal or repositioning of the cams whereby price changes and variations can be quickly and easily accomplished.
