Abstract: An adhesive tape case provided with a cutter has a case body comprising two separable portions. The cutter is fixed adjacent to a tape outlet of the case body. In addition, two rollers for advancing a length of tape is provided adjacent to the tape outlet and driven through two gears. The gears are driven by the operation of an operational knob through a rack plate. The rack plate is adapted to engage with one of the gears when moving forward and to separate therefrom when moving backward. The operational knob is operated on the exterior of the case body or on the inside thereof, depending upon the size of the tape roll employed.
