Title: Method of supplementing lead in x-y plotter
Inventor: TATEZAWA HAJIME
IPC: B43L13/00
Filed: 1987-11-25
Abstract: PURPOSE: To shorten the writing time by supplying a lead from a lead feeder to an empty pen being held at each pen holding part of a pen stocker when a writing head is writing on a writing face. CONSTITUTION: A writing head holding a pen P returns the pen back to the pen holding part of a stocker 16 when the lead thereof runs out and holds a pen P refilled with a lead being held by other holding part 18 thus sustaining the writing operation. Subsequently, the empty pen P is moved to a lead supply position directly under a lead container 24 through rotation of the discs 16a, 16b of the stocker 16. Consequently, an arm 56 is subjected to osctilatory rotation through a motor 52 and collides against the protrusion of an opposite arm 32 to lift the arm by the inclining face thereof. Consequently, a lead 26 is inserted into a lead guide 28 and dropped into the pen P after repeating collision a plurality of times. Subsequently, a cam 47 turns to lower the arm 56 thus pushing the lead 26 and discharge the residual lead into a residual lead receiver 48 before being reset.  According to the arrangement, refilling operation can be carried out during the writing operation.
