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 lead chuck of a mechanical pencil to be assembled into a lead feeding mechanism of a rear end knock type, an automatic lead feeding type and an extremity end knock type mechanical pencil in which it is arranged within the sleeve through a resilient member in such a way as it may be advanced or retracted. A lead holding part is formed at the extremity end portions of the divided surfaces of the chuck members which are fully divided into two sections along an axial plane. The lead holding part is formed with several teeth for use in holding the lead under four-point or six-point contacted condition within axially formed grooves made at the central portions of the divided surfaces. The teeth are projected in several rows and formed at the raised surfaces of the grooves. Stepped partial circumferential projections are projected and formed at the central part of the raised parts of the front portions of the semi-circumferential flange which are projected and formed at the outer circumference at the rear ends of the chuck members. Other stepped projections are formed at both end portions of the raised rear surfaces of the opposite sides of the flange, thereby the extremity end of the lead supplying cylinder extremity end receiving element is abutted against the rear raised surface of the flange part from the rear end side of the lead chuck. Forces applied from both directions, when the front raised surface of the flange part receive the rear end of the resilient member installed between it and the sleeve, are utilized and each of the chuck members generates a flexing phenomenon and the chuck members may then perform an instantaneous expanding operation under this flexing force.

摘要： An angle adjusting device includes a pedestal, a pair of guide members having an arcuate track, an oscillation body moved along the track of the guide members, and a moving member for moving the oscillation body to adjust the angular position of the oscillation body around an oscillation axis. The moving member has a motor provided in the pedestal, a linkage shaft provided in the oscillation body, and a linkage mechanism interposed between the motor and the linkage shaft. A principal linkage member of the linkage mechanism is linked to a top end portion of an output shaft rotatably around an axis parallel to the oscillation axis, and linked to the linkage shaft to be linearly movable in its axial direction. The guide members have two flat reference planes, and fixed in a state where those reference planes are contact with two flat setting planes of the pedestal.
