Abstract
An automatic pencil sharpener includes a pencil sharpening mechanism and a sharpening switch within a central receiver configured to receive a pencil through an access opening. The pencil sharpening mechanism and sharpening switch are operatively connected to a sharpener control unit. When a pencil actuates the sharpening switch, the sharpening control unit powers the pencil sharpening mechanism and the notification light illuminates in a first color. At a subsequent event or time when the pencil is substantially fully sharpened, the notification light illuminates in a second color. The illumination is preferably produced by at least one green LED and one red LED.
