摘要： A feeding pencil includes a main body, a leading tube, a middle tube, and a ratchet mechanism. The middle tube is engaged to the leading tube to be relatively rotatable. A relative rotation between the leading tube and the main body in one direction moves a drawing material forward. The ratchet mechanism allows the relative rotation between the leading tube and the main body in the one direction, and regulates the relative rotation in another direction. The ratchet mechanism includes an elastic projecting part and a concave-convex part. The concave-convex part engages with the elastic projecting part to be movable in an axial direction and rotatable. A protrusion disposed at a center tube removably engages with an annular convex part disposed at an outer surface of the leading tube in the axial direction.

摘要： A feeding pencil includes a body, a leading tube, a middle tube, a pipe member including drawing materials, a movable body, a holding member, and a sliding part. The drawing material moves forward in the leading tube when the pipe member engages with the leading tube in a rotating direction by moving the sliding part forward by a predetermined amount, when the leading tube and the body are rotated relatively in one direction while the pipe member is engaged with the leading tube in the rotating direction. The sliding part includes a stick-like part with a spring, and the stick-like part is inserted into an opening of a housing, and the sliding part is urged rearward by the spring when one end of the spring abuts the housing, and the other end of the spring abuts a face protruding radially outwardly from the stick-like part.

摘要： A composite writing instrument having a lower tubular casing accommodating therewithin two retractable mechanical pencil units spaced by about 180.degree.. An upper tubular casing encloses a cam mechanism for effecting a reciprocal rotational motion through about 180.degree. around the axis of the instrument and engaging both pencil units for alternately shifting them in the axial direction whereby the two pencil units can be alternately advanced to a writing position through an opening at the lower end of the lower tubular casing, or retracted to a retracted position within the lower tubular casing. A feeding operation for advancing the lead of the pencil unit in the writing position is effected by reciprocating of the upper tubular casing in the axial direction.
摘要翻译：一种复合书写工具，具有一个下部管状套管，其中容纳有间隔约180度的两个伸缩式自动铅笔单元。上管状壳体包围凸轮机构，用于围绕仪器的轴线进行大约180度的往复旋转运动，并且与两个铅笔单元接合，以便在轴向上交替地移动它们，由此两个笔单元可以交替地前进到书写位置通过下管状壳体的下端处的开口，或者缩回到下管状壳体内的缩回位置。用于使书写位置中的铅笔单元的引线前进的进给操作通过上管状壳体沿轴向的往复运动来实现。

摘要： A mechanical pencil has at the forward tip portion thereof a movable cylinder made up of a lead-protecting tube and an outside tube covering the lead-protecting tube. Lead extends through the lead-protecting tube and further through a chuck provided above the movable cylinder. A ring is provided for applying a load to the movable cylinder to add to its plunging movement for withdrawing into the pencil proper, the pencil proper having the forward tip directed upward at this time. The ring is the outside of the lead-protecting tube leaving a clearance between the ring and the lead-protecting tube. The outside tube is expanded at the bottom thereof so as to retain the ring therewith at the time of withdrawing the lead into the pencil proper.
