Abstract
A time delay mechanism positioned in the pencil sharpener housing near the entry point of the pencil delays the entry of the pencil into the sharpening cavity and simultaneously moves the helical cutting mechanism inwardly into engagement with a leaf spring contact thereby causing actuation of the pencil sharpener motor and rotation of the helical cutting mechanism before the entry of the pencil point into the sharpening cavity.
