A feeding pencil includes a main body including a main body barrel having a tubular shape, a front barrel detachably engaged with the main body barrel, and a cartridge disposed in the front barrel to receive a drawing material. The cartridge includes a tubular portion provided on a rear side of the cartridge, the main body includes an insertion portion provided on a front side of the main body and configured to be engaged with the tubular portion. When the cartridge is tilted from the main body, an engagement between the tubular portion and the insertion portion is released.

Mechanical pencil

A mechanical pencil has: a shaft tube; a ferrule unit supported by the shaft tube; a lead holding unit having a chuck configured to relatively move with respect to the ferrule unit to eject lead held by the same; and an indication body provided movably in an axial direction. The indication body delimits from rearward a lead storage space formed rearward the chuck in the shaft tube. The indication body located at least at a predetermined position is viewable from outside the shaft tube. A length along the axial direction between a rear end of the lead storage space and a front end of the ferrule unit, in a state where the indication body has moved most rearward along the axial direction, is equal to or more than twice a length of spare lead to be stored in the lead storage space.

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.
