The invention concerns a pencil comprising a lead, a cartridge for at least partially receiving the lead, and a protective cap having a device for shaping the lead.
Pencils of the above-indicated kind are known, for example from DE 196 16 613 C1. In accordance therewith the device for shaping the lead is in the nature of a sharpener. The sharpening operation is effected after fitment of the cap containing the sharpener by rotation of two sleeve portions relative to each other, whereby a rotary drive for the lead is actuated. A slipping clutch serves to limit the advance movement of the lead by the rotary drive.
U.S. Pat. No. 2,514,761 discloses a protective cap with integrated sharpener and a holder for a lead pencil. When the holder is rotated with respect to the protective cap with the sharpener, an advance movement of the lead pencil is effected until an abutment is reached. The advance movement is therefore restricted to a predetermined amount.
The object of the invention is to develop the pencil of the kind set forth in the opening part of this specification in such a way that handling thereof is simplified.
