摘要： A mechanical pencil is disclosed in which lead feed occurs automatically upon lifting of the pencil from the paper surface or the like and in which the slider can be locked in a retreated position when the pencil is not in us. The mechanical pencil includes a tip member fitted in the front end of a shell removably, a sleeve disposed slidably in the interior of the tip member, a lead feed mechanism which is mounted in the interior of the sleeve and which permits a forward movement of a lead but inhibits a backward movement of the lead, an ejection bar mounted on the front end side of the sleeve, with the lead extending through the ejection bar, a slider disposed slidably within the tip member and having a locking engaging portion capable of engaging the tip member disengageably, the slider imparting a predetermined frictional force to the lead, and a resilient member disposed between the slider and the ejection bar, the resilient member having an urging force stronger than a lead gripping force of the lead feed mechanism under.

摘要： A propelling or automatic writing implement having a lead which can be projected from the implement without pushing. An inner frame having a chuck assembly for permitting advance of the lead but preventing retraction of the lead and a lead protecting tube having a holder for holding the lead with a suitable frictional force are housed in a main body and slidable axially thereof. A mechanism is provided for retracting the frame and the tube by a reaction to which the lead is subjected when pressed against the writing surface with a force of considerable magnitude and for returning them when the lead is released from the force, while permitting the tube to move backward and forward relative to the frame in the course of the reciprocating movement. The lead can be projected by the relative movement of the tube and the frame.

摘要： An automatic pencil employing axial movement of a lead piece guide and a lead piece chucking mechanism. After a length of protruding lead rod is used up, the lead piece guide is caused to retract in the same amount as the wearing away of the lead rod. By pressing the tip of the lead rod against another object, the lead rod is caused to move back with the chucking mechanism. After the rod is retracted until the tip aligns with the tip of the guide, the rod and lead piece guide will be moved back. The rod will then advance when the holder is moved away from the object while the lead piece guide will be left in the retracted position due to a large friction between the friction member and the guide means. By this operation, the rod is protruded from the guide at substantially equal length to the stroke of the retracting movement. In other words, the guide is moved back at each time when the rod moves back and forward to allow the rod to protrude by a constant length which is irrespective to that which has previously protruded.
摘要翻译：一种铅笔引导件和引线片夹持机构的轴向运动的自动铅笔。在使用一段突出的引线杆之后，引线引导件以与引线的磨损相同的量退回。通过将引线的尖端压靠在另一个物体上，引导杆通过夹紧机构向后移动。在杆缩回直到尖端与引导件的尖端对准之后，杆和引导件引导件将被移回。当保持器从物体移开时，由于摩擦构件和导向装置之间的大的摩擦，引导件引导件将被留在缩回位置，所以杆将会前进。通过该操作，杆从引导件以与收回运动的行程基本相等的长度突出。换句话说，当杆向后和向前移动时，引导件向后移动，以允许杆突出一定长度，这与先前突出的杆不同。

摘要： In an automatic mechanical pencil, breakage of a lead can be prevented and a lead protruded from a slider (4) can be housed in the slider. At the frond portion of a mouthpiece, the slider is disposed movably in an axial direction. Within the mouthpiece (2), a chuck and a chuck ring (8) are provided so that an advancing movement of the lead is permitted, but a retracting movement of the lead is prevented. Between the slider and the chuck, a lead supply spring (19) is provided. The chuck ring is disposed movably in an axial direction in the mouthpiece and pressed in an axially forward direction by a writing pressure spring (24). At the rear portion of the chuck, a chuck stopper (23) is provided with a distance (22) from the rear end of the chuck. After the chuck retracts in a predetermined distance, it is stopped by a chuck stopper. Even if the retracting movement of the chuck is stopped, the slider and the lead can be housed in the mouthpiece since the chuck ring can retract by being pressed by the slider.

摘要： An eversharp pencil provided in the interior of an outer cylinder (1) or a front member (2) with a slider (11) contacting a lead and the outer cylinder (1) with different levels of frictional resistance, and a resiliently-supported cushion sleeve (8) in addition to a lead feed means adapted to feed the lead by ageneral knocking operation, so as to press and stop pressing the tip of a worn lead (19) against the paper and thereby project the lead (19) from a lead guide (12) to such an extent that corresponds to a distance by which a slider is backwardly dis. placed. Owing to this construction, the feeding of the lead can be done easily by only the above-mentioned pressing operation with the fingers left on the same portion of the outer cylinder (1).
