Description

[Detailed Description of the Invention] Technical Field The present invention relates to an eraser with a cleaning tool that combines an eraser containing magnetic powder and a cleaning tool for collecting eraser debris.

PRIOR TECHNOLOGY To dispose of the debris generated by using an eraser, there are two methods:
This is done by wiping it off with a rag or by hand. However, with these methods, it is difficult to clean quickly and reliably. Therefore, in order to solve this type of problem, it may be possible to mix magnetic powder into the eraser to generate magnetic rubber debris, which is then collected using a magnet. However, even if the magnetic rubber debris is simply collected using a magnet, it is difficult to remove the magnetic rubber debris from the magnet.

Purpose of the invention Therefore, the purpose of the present invention is to provide an eraser with a cleaning tool that is easy to use and allows eraser waste to be easily collected and disposed of.

Structure of the Invention To achieve the above object, the present invention will be explained with reference to the reference numerals in the drawings showing the embodiments for ease of understanding. , a cleaning case 4 that houses the combination 9 and has a separation part 12 for preventing magnetic eraser debris 8 from being directly attracted to the permanent magnet 3; and the combination 9 and the case 4. and a magnetic piece 5 fixed to the case 4 so as to be detachably integrated by the action of the permanent magnet 3.

Effects of invention According to the above invention, the following effects can be obtained.

(a) Since the magnetic eraser waste 8 can be attracted through the cleaning case 4 and discarded by removing the permanent magnet 3 from the case 4, cleaning of the eraser waste 8 is easy and You can definitely do it.

(b) Since the combination 9 is made up of the permanent magnet 3 and the eraser 1, there is little risk of the permanent magnet 3 being lost.

(c) Since the magnetic piece 5 is fixed to the cleaning case 4, the assembly 9 and the cleaning case 4 can be stably integrated when collecting eraser waste 8. Therefore, it is possible to provide an eraser and a cleaning device that are easy to use.

(d) A combination body 9 with a magnetic piece 5 provided in the case 4
Permanent magnet 3 and case 4
It becomes possible to maintain a constant relationship with the eraser dust 8, and the adsorption effect of eraser debris 8 can be maintained constant.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

The eraser with a cleaning tool according to the first embodiment shown in FIGS. 1 to 4 consists of an eraser 1 containing magnetic powder, a cover 2, a permanent magnet 3, a cleaning case 4, and a magnetic piece 5.

The eraser 1 is uniformly mixed with extremely fine magnetic powder (for example, iron, nickel, soft ferrite) to the extent that it does not substantially affect the function of erasing characters, that is, the function as an eraser.

The cover 2 is made of synthetic resin and has some elasticity, and has a recess 6 into which the lower part of the eraser 1 is inserted.
It has a locking protrusion 7 on the inner circumferential surface of the eraser 1, and by biting the protrusion 7 into the side surface of the eraser 1, the eraser 1 is held detachably.

The permanent magnet 3 is strong enough to attract magnetic eraser debris 8 through the case 4, and is fixed to the bottom surface of the cover 2.

The combination 9 obtained by integrating the eraser 1, the cover 2, and the permanent magnet 3 is the case 4.
It is removable as shown in FIG.

The cleaning case 4 has a first recess 10 for accommodating the combination 9 and a second recess 1 for accommodating eraser waste 8.
1, and both recessed portions 10 and 11 are separated by a separating portion 12. The magnetic piece 5 is fixed to the bottom of the recess 10 in order to detachably hold the assembly 9 in the recess 10 by adsorption with the permanent magnet 3, and is made of an iron piece.

When erasing characters on the paper 13 with the eraser with a cleaning tool constructed in this way, use the eraser 1 to erase the characters with the combination 9 and the case 4 integrated as shown in FIGS. 1 and 3. Erase. When cleaning the magnetic eraser waste 8 generated by this, the second recess 11 of the case 4 is brought close to the magnetic eraser waste 8 with the combination 9 and the case 4 integrated as shown in FIG. This action causes the rubber debris 8 to be adsorbed to the separating section 12. When discarding the collected eraser waste 8, the assembly 9 is separated from the case 4 at the disposal place. That is, the magnet 3 is separated from the case 4. As a result, the action of the magnet 3 causes the magnetic eraser waste 8 to
The rubber debris 8 falls as shown in FIG. After discarding the rubber waste 8, reassemble the assembly 9.
and case 4 are integrated.

As is clear from the above, according to this embodiment, the effects (a) to (d) explained in the section of the effects of the invention can be obtained. Further, since the case 4 has the second recess 11, it is possible to stably hold the magnetic eraser debris 8 once attracted. That is, if the bottom of the case 4 does not have the recess 11, the attracted magnetic eraser debris 8 will touch an object and move or fall, but if the case 4 has the recess 11 as in this embodiment, there is no such fear. Further, as shown in FIG. 4, since the eraser 1 and the cover 2 are separably engaged, when the eraser 1 runs out, only the eraser 1 can be replaced with a new one.

Next, an eraser with a cleaning tool according to a second embodiment of the present invention shown in FIGS. 5 to 8 will be described. However, in FIGS. 5 to 8 and FIGS. 9 to 11 showing the third embodiment described later, parts common to those in FIGS. 1 to 4 are given the same reference numerals. The explanation will be omitted.

In the second embodiment shown in FIGS. 5 to 8, a permanent magnet 3 is arranged inside the cover 2, and in order to reduce the influence of the demagnetizing field of the permanent magnet 3, a magnetic piece 14 made of an iron piece is arranged. is integrated into the permanent magnet 3. Further, in this embodiment, the cover 2 is made of relatively strong and flexible paper, and is formed so that only the tip of the eraser 1 is exposed. Therefore, as the eraser 1 decreases, the eraser 1 is pushed up above the cover 2 as shown in FIGS. 7 and 8.

According to this second embodiment, the same effects as those of the first embodiment can be obtained. Furthermore, since the permanent magnet 3 is arranged inside the cover 2, the bottom surface of the assembly 9 becomes flat, improving the appearance. Furthermore, since the magnetic pieces 14 are stacked in the thickness direction of the permanent magnet 3, the influence of the demagnetizing field is reduced, making it possible to obtain a large force with a thin magnet 3. Furthermore, even if magnetic eraser debris 8 or other magnetic powder is attracted to the assembly 9, it is not directly attracted to the permanent magnet 3, but only to the outer peripheral surface of the cover 2, so it can be removed relatively easily. You can.

In the third embodiment shown in FIGS. 9 to 11, a permanent magnet 3 is embedded in the bottom surface of the eraser 1 without providing anything equivalent to the cover 2 shown in FIGS. 1 to 8. In this way, we aim to simplify the configuration. Even with this configuration, the effects (a) to (d) described above can be obtained. Further, the effect of the recess 11 can also be obtained.

Although the embodiments of the present invention have been described above, the present invention is not limited thereto and can be modified. For example, a brush may be attached to the lower end of each case 4. The cover 2 and the case 4 may be made of magnetic material.
