Eraser feeding mechanism attached to mechanical pencil

Abstract

To provide an eraser feeding mechanism attached to a mechanical pencil, which eliminates the inconvenience of an eraser attached to a conventional mechanical pencil and enables the eraser to be used simply and quickly.SOLUTION: A folder loaded with an eraser is attached to the inside of the top of the mechanical pencil, and a protrusion connected to this folder is provided on the outside of the mechanical pencil, and by pressing this with the fingers, the eraser is pushed out from the front of the mechanical pencil in front of the lead, making it possible to erase letters, etc. Also, when the fingers are released, the eraser automatically returns to its original position, allowing the user to instantly return to the action of writing letters, or the like.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] This device is an eraser extension mechanism attached to a mechanical pencil that allows you to quickly erase written characters, etc. [Background technology]

[0002] When writing something using a mechanical pencil, to correct it, one usually uses the eraser attached to the back of the mechanical pencil, but the eraser usually has a protective cap, which must be removed, and then the mechanical pencil must be held upside down to erase the letter, and then to write something again, the mechanical pencil must be held upside down again. Furthermore, due to this inconvenience, there have been cases where people have intentionally missed opportunities to use a mechanical pencil. Problem to be solved by the invention

[0003] Conventionally, when writing letters or the like using a mechanical pencil, if you want to correct them, you use the eraser attached to the back, but this is quite troublesome, so you may have to prepare a separate eraser or hesitate to write letters or the like using a mechanical pencil at all. The present invention has been devised to solve the above-mentioned problems.

[0004] A folder that works in conjunction with a protrusion on the outside of the mechanical pencil body is provided above the lead-advancing mechanism inside the mechanical pencil body, and an eraser with a hole is loaded into this. By pressing the protrusion on the outside of the mechanical pencil body, the eraser loaded in the folder is pushed forward from the tip of the lead. When the user releases the folder, a spring attached to the folder returns the eraser to its original position. The present invention is an eraser feeding mechanism attached to a mechanical pencil, which has the above-mentioned configuration.

[0005] The effect of this invention is 1. This eliminates the need for the conventional method of removing the eraser cap, holding the mechanical pencil upside down, erasing the letters, etc., and then holding it again, which is a cumbersome process, and therefore reduces stress. 2. You can hold the mechanical pencil in your hand as you would write, pull out the eraser to erase the letters, and then immediately start writing again, so you can continue working without interrupting your thoughts. 3. A mechanical pencil using this invention makes it easy to correct letters, etc., and is a writing instrument that makes full use of the inherent advantage of a pencil, which is that you can erase what you have written. [Brief explanation of the drawings]

[0006] As shown in Figure (1), the eraser extension mechanism included with this mechanical pencil consists of an eraser holder (3) mounted on top of the lead extension mechanism of the mechanical pencil, with a hole in the center inserted into it. A spring (8) is installed between a support plate (4) and a movable support plate (5). The eraser holder (3) is connected to the movable support plate (5) and, by pressing a protrusion (7) on the outside of the mechanical pencil body (6) with a finger, the cover (1) is pushed up from the front of the mechanical pencil to extend the eraser (2). This eliminates the need to reposition the mechanical pencil to erase writing. Furthermore, the eraser (2) remains extended as long as the protrusion (7) is pressed, and automatically returns to its original position via the spring (8) when the finger is released. Since the lead of the mechanical pencil remains extended, writing can continue. [Explanation of symbols]

Claims

1. An eraser holder is placed on top of the lead advance mechanism of a mechanical pencil, and an eraser with a hole in the center is loaded into it. A protrusion connected to the holder is provided on the outside of the mechanical pencil body, and by pressing this protrusion with the fingertips, the eraser loaded inside pops out to the end of the mechanical pencil lead. When the finger is released, the eraser returns to its original position. This invention provides an eraser advance mechanism attached to this mechanical pencil.

2. The eraser according to claim 1 has a hole in the center and is loaded into an eraser feeding mechanism attached to a mechanical pencil.
