The pen cap and pen barrel have respectively a first coupling portion and a second coupling portion that correspond to and engageable with each other. The first and second coupling portions form a first coupling position to allow the magnet and metal element attracting to each other to form an anchor condition, and a second coupling position to separate the magnet and metal element to release the anchor condition. Thus by moving the pen cap against the pen barrel to the second coupling position, the pen cap can be separated from the pen barrel to make use of the pen easier.

    Abstract: The invention relates to a writing device capable of electronically recording what was written. A pen body comprising microelectronics, an acoustic emitter, an electromagnetic sensor, and a writing tip with ink reservoir is featured. A detachable cap also contains microelectronics, multiple acoustic sensors, and an electromagnetic emitter. Microelectronics in the cap determines the distance of the acoustic emitter in the pen body to multiple acoustic sensors, and by triangulation can determine the exact distance of the acoustic emitter located near the writing tip. Electromagnetic emitters and sensors are used to synchronize microelectronics with the sending times of each acoustic pulse. The exact distance of the acoustic emitter is also determined without electromagnetic emitters and sensors, by the difference in phase or timing of each pulse of acoustic signals, at two or more acoustic sensors. A computer may be used to generate a two-dimensional image map of what was written.

  • Patent number: 6488426
    Abstract: A writing instrument is provided including a gripping section arranged along a portion of the writing instrument normally used for gripping and a writing tip extending from the gripping section. The gripping section may be provided on a replaceable cartridge element which is inserted into a cartridge-receiving cavity in the writing instrument body. A soft, resiliently deformable gripping member is provided on the gripping section and is preferably tubular in shape. The gripping member includes a smooth surface which may include a slightly elevated or raised pattern. The elevated pattern may comprise a plurality of interconnected parts so as to form a continuous lattice or pattern such as hexagons. The pattern is preferably continuous over the entire smooth surface. The elevated pattern is resiliently compressible with respect to the smooth surface so that a user's fingers may deform the elevated pattern to provide additional traction during use.

  • Patent number: 6471433
    Abstract: A pen having a 3-dimensional pattern has at least one flexible strip. The flexible strip is sandwiched between a pattern ring and a liner ring with the 3-dimensional pattern partially protruding out of the pattern ring from a corresponding through hole. The liner ring abuts a bottom end of a connecting ring. The connecting ring is formed with an annular flange on its outer surface. The pattern ring abuts the annular flange to enclose the liner ring. A top end of the connecting ring is clamped onto a barrel of the pen, and a bottom end of the liner ring is threadingly connected to a tip of the pen.

  • Patent number: 6439791
    Abstract: A grip is used for a mechanical pencil including a shaft tip portion, a core guide, and a core. This grip is formed into a tube-shape. The grip includes a tip portion, a base portion, and a spacing portion. The tip portion has a tip and a through hole portion and is shaped into a conical-shape so that a diameter thereof is reduced towards the tip. The base portion has a predetermined inner diameter such that the shaft tip portion of the mechanical pencil is treed into the base portion. The spacing portion is formed inside the tip portion and houses the core guide and the core. The core is movable in and out of the tip portion via the through hole portion.

  • Patent number: 6435752
    Abstract: A correction pen with a pressure adjusting structure having an increased interior pressure of the pen so that the correction liquid may flow out of the pen successfully. The correction pen comprises a pen tube, a penpoint seat, and a ventilating ring. The ventilating ring is installed at an end portion of the pen tube. The lower edge thereof extends to the pen tube, and the penpoint seat is inserted into an end portion of the pen tube. The tightening portion at the lower end of the ventilating ring encloses the periphery of the penpoint seat. Thereby, a pressure adjusting structure with the ventilating ring is formed so that air flows unidirectionally, and thus a correction pen with a pressure adjusting structure is formed.

    Abstract: A writing implement having a cap member is provided and is a direct-flow type (liquid ink type) writing implement including: a barrel cylinder; a holder holding a pen core at a front end of the barrel cylinder and further having inside the barrel cylinder, an ink tank for storing a liquid ink and a collector for temporary retention thereof. The collector, barrel cylinder and ink tank are formed of a clear, transparent material. A mouthpiece at the outer periphery of the holder is formed of a resin material having the same color as the ink held in the ink tank or having the same color as the written ink. The barrel cylinder may have a partition wall, positioned near to the center, on the side (rear side) opposite to the position where the collector is arranged, forming an ink tank in a space inside the barrel between the rear end plate of the collector and the partition wall.

  • Patent number: 6406203
    Abstract: The combination of a writing instrument, a lanyard and a panel. The writing instrument has a cap and a body. The lanyard has an end attached to the cap, another end attached to the body, and an intermediate region extending between the two ends. The panel has an aperture through which the lanyard's intermediate region extends. The aperture is large enough to allow the lanyard intermediate region to pass freely through the aperture, yet the aperture is small enough to prohibit the cap and the body from passing through the aperture. The panel remains attached to the apparatus, although the panel can slide relative to the intermediate region of the lanyard.
