ABSTRACT:
A pencil head for automatic pencil drawing is provided with an up-and-down moving mechanism for one of pencil leads held on a periphery of a holding turret and a mounting mechanism for the holding turret, the up-and-down moving mechanism comprising a spring for raising a resilient member grasping the pencil lead which slides through a tubular holder fixed in the periphery of the holding turret and a pushing stick for pushing down the pencil lead, which is supported by a slider sliding along a rail, and the mounting mechanism comprising a coupler projected coaxially from the holding turret with a stair-stepped male cross-section and a socket for engaging and rotating the coupler with a slitted stair-stepped female cross-section corresponding to the stair-stepped male cross-section of the coupler. Accordingly, high fidelity and quick response of the pencil head used for automatic pencil drawing and shortening of time duration required therefor can be realized.
