摘要： In a free-ink type low-viscosity water-based ball point pen, the low viscosity water based ink 17 contains 40% or more of water as a main solvent and has a viscosity of 1.5 cps to 60 cps at a normal temperature. A collector 6 has a slender, slit-like ink groove 16 and an air vent groove 14. In a zone covering from a collector air-venting portion 15 to an outside air with which the collector air-venting portion 15 is communicated the collector 6 has a mouth piece 5 having provided therein the thin and elongate air vent groove 14. The maximum amount of ink stored in the collector 6 is made 15% or more of the capacity of an ink tank 9. The ink tank 9 is made detachable and has its main body formed of transparent or semi-transparent synthetic resin, the main body therefore enabling a residual amount of ink 17 to be visually recognizable from outside.

摘要： A clicking-type writing implement includes a writing element having a writing portion at its distal end, a spring for urging the writing element toward the end, and a clicking rod loosely fitted interlocked with the writing element so as to project from a barrel cylinder. Upon depression of the clicking rod, the engaging rib of a rotor in the barrel cylinder and the engaging bead in the inner cylinder engage with each other, so that the writing element projects and stays projected from a front portion of the barrel cylinder. This clicking-type writing implement also has a so-called double clicking mechanism and a safety mechanism. According to the double clicking mechanism, the clicking rod is projected upon depression and is retracted upon further depression. According to the safety mechanism, when the engaging bead and the engaging rib engage with each other, the projecting state of the writing portion of the writing element is maintained, and when the engaging bead is lifted, the writing element is retracted. No cam surfaces are formed on the inner surface of the barrel cylinder. In the inner cylinder, a cam is formed on the front edge of a cylindrical portion inserted and fixed in the barrel cylinder.

摘要： A ballpoint pen for use with ink having thixotropic (shear viscosity decreasing properties) and a joint for regulating the flow of the ink to the pen's tip through an entrance in the tip. The joint includes a valve chamber which is disposed in an approximately middle portion of the joint with respect to the axial direction thereof for holding a ball therein with play and has a ball seat in the rear part thereof, a cavity in front of the valve chamber and a conduit communicating with an ink reservoir. In this arrangement, in order to allow the ball to fit on the ball seat to prevent ink from flowing backward when the ballpoint pen is oriented upward and in order to ensure an ink flow when oriented downward, the joint portion is constructed such that an axis of path holding the ball valve with play, defined by the top surfaces of the ribs formed on the peripheral wall of the valve chamber, is made eccentric to the axis of the entrance and a channel is provided by the ribs on one side of the valve chamber space for the ink to flow therethrough.

摘要： A point assembly has a multiple number of channels on its inside for establishing commutation of ink to the pen point, and the extradius of these channels is set approximately equal to or greater than the radius of the ball. Further, the point assembly has a sealing face having a curvature R which is approximately equal to that of the ball, and has a ball seat, on the rear side of the ball, having a curvature R being approximately equal to that of the ball. The surface roughness of these elements is set 5 .mu.m or below. Further, this point assembly can be formed in an open V-shaped tapered configuration. Alternatively, the point assembly can be configured in combination with a spring provided therein which continuously urges the ball forwards or in combiation with an anti-backward leakage mechanism.

摘要： Toner attracted onto an electronic latent image formed on the surface of a photosensitive drum is transferred onto a transfer sheet, using a transfer bias from a transfer bias roller. A transfer belt for transporting the transfer sheet includes an anisotropic conductive layer composed of conductive members and an insulating member. The anisotropic conductive layer is conductive only in the thickness direction thereof and insulating in the other directions. This makes it possible to offer a transfer device that can prevent a transfer electric field from spreading and toner from being projected, and that boasts excellent sheet transportability.
