Abstract: An improved paper tape control unit is provided for use with calculators, adding machines and the like requiring use of paper tape in roll form. The paper tape control unit supplies the paper tape to the associated machine and provides automatic, intermittent activation of a control unit drive motor to rewind used paper tape discharged from the machine. In one form, the control unit drive motor is coupled with a standard platen drive motor of a business machine for concurrent operation to intermittenly rewind the tape onto a take-up reel. In another form, the control unit drive motor is powered independently by a separate power source such as batteries with a control unit housing to rewind the used tape onto a take-up reel.
