The composite holding tool includes a front barrel, a rear barrel rotatably connected to the front barrel, a plurality of holding bodies housed in the front barrel non-rotatably relative to the front barrel and movably in an axial direction, a cam cylinder that rotates integrally with the rear barrel, and can selectively hold any of the plurality of holding bodies, with a tip of the holding body protruding from a tip of the front barrel, by a relative rotation between the front barrel and the rear barrel, and a cartridge connected to the rear barrel or the cam cylinder and placed in the rear barrel.
Abstract: A composite writing implement is capable of being used as a ball-point pen, a mechanical pencil or a stylus pen. The composite writing implement includes a barrel, a pencil lead feeder unit axially slidably placed in a front part of the barrel, a ballpoint refill unit disposed behind and coaxially with the pencil lead feeder unit in a back part of the barrel and including a ballpoint refill case and a ballpoint refill fixedly held in the ballpoint refill case, a rotary cam operatively connecting the ballpoint refill case and the pencil lead feeder unit, and a cap put on the ballpoint refill case so as to cover the ballpoint tip of the ballpoint refill, provided with a stylus tip, capable of being used as a stylus and means for turning the rotary cam through the ballpoint refill case to make the pencil lead feeder feed a lead.
Abstract: There is provided a clip structure that can be used with a clip rotated and a clip structure assembling method. The clip structure includes, a clip body that is formed into a substantial U shape to form a holding portion in which a thin object to be clipped is held, a clip securing member for securing the clip body so that a side of an opening of the clip body can rotate along an arc and stop, and an elastic body that urges the clip body along a rotation axis of the clip body toward the clip securing member is provided to urge the clip body toward the clip securing member.
Abstract: A knock-type liquid container includes a body having a tank that holds a liquid, and an outlet provided at a forward end, a piston in the tank, and a piston-advancing mechanism having a knocking body that projects rearwardly of the body for advancing the piston forwardly when the knocking body is knocked in an axial direction of the container. A rearward end surface of the rear cap that forms a rear end surface of the container, except the knocking body is not normal to the axial direction, but makes an angle other than an approximate right angle with the axial direction. A distance between a rear end surface of the knocking body at a non-knocking position and a rearmost portion of the rearward end surface of the container, except the knocking body, is less than a stroke of the knocking body required for advancing the piston.

Abstract: In a liquid container, the dimension of inside diameter of a liquid supply portion is not subject to any restriction, and also a liquid leakage suppressing mechanism that is not subject to any restriction by the viscosity of stored liquid is provided. A liquid container includes a body having a tank for storing a liquid; a supply mechanism which is connected to the tip end portion of the body and has a brush for supplying the liquid; and a drive mechanism for pushing out the liquid L in the tank T to the supply mechanism. A valve which is normally closed and can be opened only when the drive mechanism is operated is provided between the tank and the supply mechanism.
Abstract: A push-button writing implement includes a barrel having at least a transparent or semitransparent part, a refill axially slidably contained in the barrel, and provided with a writing tip, and a refill-operating mechanism including a push button, and a return spring and designed so as to be operated by the push button to project the writing tip of the refill from a tip of the barrel and to retract the same into the barrel. A front stopper ring having the shape of an O ring is put on the refill, a fancy member is axially slidably put on part of the refill extending backward beyond the front stopper ring, and the fancy member is moved up and down along the refill when the refill is moved by resilience of the return spring by operating the refill-operating mechanism.
Abstract: In a stick-like object receiving member having safety precautions, which receives a stick-lik object, a sufficient air passage is secured without exerting an influence on the size of the stick-like object or the receiving member. An eraser receiving member 16, which is the stick-like object receiving member, includes a cylindrical side portion 16b which engages with at least a part of the outer peripheral surface of an eraser 13, and surrounds at least a part of the outer peripheral surface of the eraser 13, and a bottom portion 16a which closes one end of the cylindrical side portion 16b. A slit 16e is formed in the cylindrical side portion 16b and bottom portion 16a so as to penetrate the cylindrical side portion 16b and bottom portion 16a in the axial direction, and the slit 16e serves as an air passage.
Abstract: It is a clip attaching structure wherein the cost can be reduced, and the appearance is excellent, and furthermore, the spring action is good. The clip is made of a thin plate metal material, and has a base part to be inserted into an outer sleeve and a main body part to be extended outside the outer sleeve, and the main body part has an approximately U-shaped cross section made by bending downward both sides of the thin plate, and between the base part and the main body part, a closing part for closing the rear end opening of the inner sleeve is provided. The main body part side of the closing part has an approximately U-shaped cross section made by downward bending both sides thereof and the approximately U-shaped cross section from the main body part is continued, and the base part side of the closing part is shaped like a plate, and the downward bent portion of both sides of the closing part is inserted into the inner sleeve when the clip is not swung.
Abstract: A cap positioning construction for positioning and mounting a cap to a barrel, includes a triangular notch formed in a step face of a barrel on which the end of a cap abuts, and a triangular extension formed at the end of the cap. The triangular extension extends toward the notch and matches the notch 12e. By fitting the extension in the notch, the cap is positioned relative to the barrel when the cap is mounted on the barrel.
Abstract: A direct liquid type writing instrument is used without running-over of ink even in an environment in which an internal pressure is higher than an external pressure. The writing instrument includes an ink reservoir containing ink, a junction core extending on a center axis, and a pen body provided integrally on a tip end side of the junction core. The ink reservoir includes a main ink reservoir, a pen core chamber in which the junction core is disposed, and a sub ink reservoir which is provided between the main ink reservoir and the pen core chamber and communicates with the main ink reservoir via a small hole. Between the sub ink reservoir and the pen core chamber, an opening/closing valve is provided to normally isolate the pen core chamber from the sub ink reservoir and to be operated so that the pen core chamber communicates with the sub ink reservoir when the pen body is operated.
Abstract: To provide a clip attaching structure wherein a base portion of a clip is not exposed from an outside, and attaching can be performed with a good appearance. An outer sleeve has a rear sleeve and a cap connected to a rear side of the rear sleeve, and the clip has a ring-like base portion fixed to the outer sleeve, a connecting portion extending from the base portion, and a clip main body extending approximately in parallel with the rear sleeve from the connecting portion. At the rear end portion of the rear sleeve, a bent portion is formed, and in the bent portion, a notch penetrated by the connecting portion and a second notch facing to the notch by about 180 degrees are formed. The base portion of the clip passes through the portion in the diameter direction of the rear end opening connecting the notch and the second notch, and goes through the bent portion, and is inserted into an inside of the bent portion of the rear sleeve.
