摘要:
The present disclosure is directed towards the design of a marking device for writing or drawing on a given surface. The marking device can be made of any material that leaves a residue or makes legible marks on a surface brought into contact with the device. The marking device of the present disclosure can be used to make precise lines or shapes on any material, including rough surfaces, such as, wood, concrete, drywall, tiles, etc. The marking device can consistently produce thin lines without needing any sharpening. The marking device can be attached to a support frame, which can serves as a handle for grasping and using the marking device. The support frame can further provide a housing to shield the marking device from damage when not in use. In one exemplary embodiment, the marking device is shaped as a razorblade and is configured to fit into any standard utility knife. In such an embodiment, the utility knife serves as the support frame for the marking device. Such an arrangement allows a utility knife to be reversibly converted into a carpenter pencil.

Provided is a mechanical pencil which is configured so that a rotatable cam is rotationally driven with an axis of the rotatable cam relative to a holder member stabled, and smooth operation of a rotational drive mechanism is ensured. The mechanical pencil includes a rotational drive mechanism 21 for driving rotationally a rotatable cam 23 according to writing pressure applied to a writing lead, and transfer rotational motion of the rotatable cam 23 to the writing lead. The rotational drive mechanism 21 includes a holder member 22 supporting the rotatable cam 23 so as to be rotatable, a first fixed cam 22c formed with a funnel-shaped inclined surface Fu and a second fixed cam 22d formed at an obtuse angle α relative to an axial direction. Cam faces of an upper cam 23a and a lower cam 23b alternately meshing with the first and second fixed cams are formed along a conical inclined surface Cs.

A marking implement comprises a main body (2) for housing a marking element (3) that is movable by sliding therein; the main body (2) comprises a broad grip portion (4) and an elongated neck (5) axially contiguous to the grip portion (4); a mechanism for sliding (7) said marking element (3), a protective cap (6) housing the neck (5) completely therein and the broad grip portion (4) at least partially. The sliding mechanism (7) comprises a movement slider (8) that is slidable axially and in a controlled manner along the main housing body (2) so as to guide the advancement and retraction of the marking element (3).

A mechanical pencil is provided having a rotational drive mechanism which gradually rotates a writing lead on application of writing pressure and allowing rotational operation of the writing lead to be known reliably. First and second cam faces 6a and 6b are respectively formed at one end face and the other end face of a rotor 6 in an axial direction, and first and second fixed cam faces 13a and 14a arranged on the body cylinder side so as to respectively face the first and the second cam faces are provided to form the rotational drive mechanism for the writing lead. A plurality of grooves 8a in the axial direction are formed at a slider 8 of a pipe end 7 which projects forwardly from a body cylinder 1. Therefore, it is possible to directly see the grooves 8a (provided for the slider 8) rotated by rotation of the rotor 6 in conjunction with the writing operation and clearly know that the writing lead is rotationally driven.

The invention relates to a writing component comprising a writing medium reservoir (34) including a filler material saturated with a writing medium and a writing tip formed by a porous nib (32) coupled to the writing medium reservoir. At least a portion of an outer surface of the writing medium reservoir (34) is covered by a sleeve (80) which also covers a portion of the porous nib (32), said sleeve (80) acting as a coupling member to join into a single component (22) the porous nib (32) and the writing medium reservoir (34). The invention also relates to a writing instrument comprising such a writing component (22).

A lead cartridge capable of holding a rod-shaped object of a sufficient length and allowing simultaneous replacement of the lead and the rod-shaped object is to be provided. A lead cartridge which includes a lead tank for containing leads and is detachably incorporated into a mechanical pencil to supply leads has a rod-shaped object feeding mechanism which propels the rod-shaped object by turning manipulation. This rod-shaped object feeding mechanism is configured of a spiral groove formed in the inner circumferential surface of a case comprising the lead tank, a guide sleeve which is arranged in the case to be unable to move in the axial direction and able to turn relative to the case and in which guide holes extending in the axial direction are formed, and a receptacle which is slidably fitted into the guide holes of the guide sleeve and has a male thread screwing into the spiral groove. A rod-shaped object is held by the receptacle. When the lead cartridge is incorporated into a mechanical pencil, the case becomes unable to turn relative to the outer sleeve of the mechanical pencil, and part of the guide sleeve protrudes out of the mechanical pencil.
