  • Actuating holder for combined electric eraser-pencil sharpeners
    Patent number: 4431038

A using draftsperson thus obtains the benefits of a separate fixed sharpener and avoids picking up and using the hand-held combined eraser-sharpener. The holding device comprises an open-ended cup structure containing a supporting spring. As the electric eraser-pencil sharpener being supported is moved under pencil insertion forces, switch actuation means activate the sharpener by depressing the motor switch.
