A handheld topical applicator. The handheld topical applicator is preferably adapted to release a precise amount of liquid onto a surface and is preferably used for various applications such as marking a surface and/or providing a proper amount of dosage for medicinal applications. The handheld topical applicator may comprise a liquid delivery system for dispensing a precise amount of liquid onto various surfaces, a projecting/retracting mechanism, and an audible and/or tactile physical feedback mechanism. The projecting/retracting mechanism may controllably retract or protrude a nib into and out of the housing, and the audible/physical feedback mechanism may provide either a physical and/or audible click once a desired amount of liquid transfers onto the surface.

A feeding pencil includes a pipe member, a leading tube, a tubular main body, a movable body, and a holding member. The pipe member is disposed inside the leading tube and loads a drawing material. The movable body extends in an axial direction includes a male screw formed across an entire outer periphery thereof in the axial direction. The holding member holds the movable body. The pipe member includes a female screw on an inner surface thereof. The female screw screws with the male screw. A relative rotation between the leading tube and the main body relatively rotates the pipe member and the holding member and acts a screwing action between the male screw and the female screw. The screwing action moves the movable body forward to extrude the drawing material from the pipe member.

A feeding pencil includes a main body, a leading tube, a middle tube, and a ratchet mechanism. The middle tube is engaged to the leading tube to be relatively rotatable. A relative rotation between the leading tube and the main body in one direction moves a drawing material forward. The ratchet mechanism allows the relative rotation between the leading tube and the main body in the one direction, and regulates the relative rotation in another direction. The ratchet mechanism includes an elastic projecting part and a concave-convex part. The concave-convex part engages with the elastic projecting part to be movable in an axial direction and rotatable. A protrusion disposed at a center tube removably engages with an annular convex part disposed at an outer surface of the leading tube in the axial direction.

Provided is a writing implement that maximizes the effective area of a viewer portion allowing visual recognition in the writing direction and that facilitates writing at a high level, at the same time. This writing implement is a writing implement A, including for example, a pen tip 20 that feeds ink from a writing implement body 10 and has a viewer portion 33 allowing visual recognition in the writing direction. The pen tip 20 is comprised of, at least, a writing part 25 and a retainer 30 having the viewer portion 33, an ink feeder portion 26 for feeding the ink from the writing implement body 10 to the writing part 25. The minimum width X of the viewer portion 33 is 3.7 mm or greater and a length Y of the viewer portion 33 is 7.4 mm or greater. The ink feeder portion 26 is arranged on one side of the viewer portion 33. Specifically, the ink feeder portion 26 is preferably adapted to be positioned on a near side during writing (on such a side that the pen tip 20 is located on an obtuse angle side of the ink feeder portion 26).

A writing instrument includes a first reservoir for dispensing a first fluid having a first property of reflectivity. A first tip member is in fluid connection with the first reservoir. The first tip member has an end with a size and shape that corresponds to a response area of the response form. A second reservoir can be used for dispensing a second fluid, which is capable of modifying the first property of reflectivity when covering the first fluid. A second tip member is in fluid connection with the second reservoir. The second tip member has an end with a size and shape that corresponds to the response area of the response form.
