Abstract

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.

First claim

What is claimed is:

1. A feeding pencil comprising:
a main body including a main body barrel having a tubular shape;
a front barrel configured to be detachably engaged with the main body barrel; and
a cartridge disposed in the front barrel for receiving a drawing material,
wherein the cartridge includes a first engagement portion provided on a rear side of the cartridge,
wherein the main body includes a second engagement portion provided on a front side of the main body and configured to be engaged with the first engagement portion, so that when the cartridge is tilted from the main body, an engagement between the first engagement portion and the second engagement portion is released,
wherein the first engagement portion includes a tubular portion having a cutout hole formed through the tubular portion, and
wherein the second engagement portion includes an insertion portion configured to be inserted into and engaged with the cutout hole of the tubular portion.

2. The feeding pencil according to claim 1 , wherein the insertion portion has a cylindrical shape.

3. The feeding pencil according to claim 1 , wherein a projection is formed on an outer surface of the insertion portion,
wherein a raised portion is formed on an inner wall surface of the cutout hole, the projection being engaged with the raised portion, and
wherein the projection and the raised portion are located on opposite sides of the tubular portion, in a radial direction of the tubular portion.

4. A feeding pencil comprising:
a main body including a main body barrel having a tubular shape;
a front barrel configured to be detachably engaged with the main body barrel; and
a cartridge disposed in the front barrel for receiving a drawing material,
wherein the cartridge includes a first engagement portion provided on a rear side of the cartridge,
wherein the main body includes a second engagement portion provided on a front side of the main body and configured to be engaged with the first engagement portion, so that when the cartridge is tilted from the main body, an engagement between the first engagement portion and the second engagement portion is released,
wherein the engagement of the first engagement portion and the second engagement portion includes a tubular portion having a cutout hole formed through the tubular portion, and an insertion portion configured to be inserted into and engaged with the cutout hole, and
wherein, when the cartridge is tilted from the main body to cause the tubular portion to separate from the insertion portion while causing the insertion portion to expand the tubular portion, the cartridge is detached from the main body.

5. The feeding pencil according to claim 4 , wherein the insertion portion has a cylindrical shape.

6. The feeding pencil according to claim 4 , wherein a projection is formed on an outer surface of the insertion portion,
wherein a raised portion is formed on an inner wall surface of the cutout hole, the projection being engaged with the raised portion, and
wherein the projection and the raised portion are located on opposite sides of the tubular portion in a radial direction of the tubular portion.

7. A feeding pencil comprising:
a main body including a main body barrel having a tubular shape;
a front barrel configured to be detachably engaged with the main body barrel; and
a cartridge disposed in the front barrel for receiving a drawing material,
wherein the cartridge includes a first engagement portion provided on a rear side of the cartridge,
wherein the main body includes a second engagement portion provided on a front side of the main body and configured to be engaged with the first engagement portion, so that when the cartridge is tilted from the main body, an engagement between the first engagement portion and the second engagement portion is released,
wherein the main body further includes a slider provided in the main body barrel and wherein the slider is slidable by a fixed amount relative to the main body barrel,
wherein the slider is disposed behind the cartridge, and
wherein the second engagement portion is provided on a front side of the slider, so that when the cartridge is tilted from the slider in a state where the front barrel is detached from the main body barrel and where the slider is moved forward by the fixed amount relative to the main body barrel, the engagement between the first engagement portion and the second engagement portion is released.

8. The feeding pencil according to claim 7 , wherein the engagement of the first engagement portion and the second engagement portion includes a tubular portion having a cutout hole formed through the tubular portion, and an insertion portion configured to be inserted into and engaged with the cutout hole.

9. The feeding pencil according to claim 8 , wherein, when the cartridge is tilted from the main body to cause the tubular portion to separate from the insertion portion while causing the insertion portion to expand the tubular portion, the cartridge is detached from the main body.

10. The feeding pencil according to claim 8 , wherein a projection is formed on an outer surface of the insertion portion,
wherein a raised portion is formed on an inner wall surface of the cutout hole, the projection being engaged with the raised portion, and
wherein the projection and the raised portion are located on opposite sides of the tubular portion in a radial direction of the tubular portion.

11. The feeding pencil according to claim 7 ,
wherein the front barrel is engaged with the main body barrel and is rotatable relative to the main body barrel,
wherein the cartridge includes:
a pipe member loaded with the drawing material;
a mobile body configured to push out the drawing material loaded in the pipe member forward; and
a holder configured to hold the mobile body behind the pipe member,

wherein the slider is moved forward by the fixed amount relative to the main body barrel, to cause the pipe member to engage with the front barrel in a rotational direction, and
wherein, in a state where the pipe member is engaged with the front barrel in the rotational direction, a relative rotation between the front barrel and the main body barrel in one direction causes the drawing material to move forward in the front barrel.

12. The feeding pencil according to claim 11 , wherein the engagement of the first engagement portion and the second engagement portion includes a tubular portion having a cutout hole formed through the tubular portion, and an insertion portion configured to be inserted into and engaged with the cutout hole.

13. The feeding pencil according to claim 12 , wherein the first engagement portion comprises the tubular portion, and
wherein the second engagement portion comprises the insertion portion.

14. The feeding pencil according to claim 12 , wherein, when the cartridge is tilted from the main body to cause the tubular portion to separate from the insertion portion while causing the insertion portion to expand the tubular portion, the cartridge is detached from the main body.

15. The feeding pencil according to claim 12 , wherein the insertion portion has a cylindrical shape.

16. The feeding pencil according to claim 12 , wherein a projection is formed on an outer surface of the insertion portion,
wherein a raised portion is formed on an inner wall surface of the cutout hole, the projection being engaged with the raised portion, and
wherein the projection and the raised portion are located on opposite sides of the tubular portion in a radial direction of the tubular portion.
