Abstract:
A drawing instrument comprising:a shaft having a tip portion defining a tip portion radius, the shaft further having a main body defining a main body radius and a main body diameter; a brush member mounted on the tip portion of the shaft and having fibers extending in an axial direction of the shaft from the tip portion of the shaft; and a brush flatter including: a casing having a space to allow the brush member of the drawing instrument to pass in the axial direction of the shaft; a shaft fitting portion formed at a proximal end portion of the casing, the shaft fitting portion having a thickness substantially equal to a difference between the tip portion radius and the main body radius, and the shaft fitting portion having an outer diameter that is substantially equal to the main body diameter of the shaft to render an outer circumference of the shaft fitting portion of the flatter substantially flush with an outer circumference of the main body of the shaft when the shaft fitting portion of the brush flatter is detachably seated on the tip portion of the shaft of the drawing instrument; and a brush pressing portion formed at a distal end portion of the casing, the brush pressing portion defining a slit-like opening through which a tip portion of the brush member pressedly passes so that an exposed tip portion of the brush member shapes into a flat form when the shaft fitting portion of the casing fittingly seats on the tip portion of the shaft of the drawing instrument, the brush pressing portion having a side wall extending in parallel with the axial direction of the shaft to align the fibers of the brush member.
