BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to a magnetic filing device, and more particularly, to a filing tool capable of easily filing and detaching operation.
2. Background Art
There has hitherto been known a type of filing tool 75 shown in FIG. 11. The filing tool 75 has a pair of holes 72 of a sheet 71 for the use of filing (a paper in generally used as the sheet 71) and a fitting 74 for fastening the tapes 73. Another type of a known filing tool has a pair of rings capable of closing/opening to be inserted through a pair of holes 72 of the above-mentioned sheet 71. Further, as shown in FIG. 12, a filing tool 83 having a clamp 82 biased by a spring 81 against a cover sheet so as to clamp sheets 71, and such a filing device, wherein many transparent envelopes are filed like a notebook, so as to allow for detachably inserting the sheets therein are also known.
Further, a scrapbook for pasting newspaper clippings or the like is also known.
However, the above-mentioned filing tools have some problems which the user feels are very troublesome. For instance, the bar-like fitting 74 or rings require excessive time for punching holes in the sheets and time for inserting the tapes 73 or rings through the holes 72 of many sheets. The filing tool 83 having the clamp 82 is troublesome for opening/closing the clamp 82 against force of the spring 81. Further, when the force of spring 81 is weak, some sheets may easily slip out. For instance, even if the user intends to take off only one sheet of paper, the remainders become scattered by all means.
Further, the tool having the transparent envelopes and scrapbook are not convenient, since the user must insert each sheet to a respective envelope or paste each of the sheets one by one.
The main object of the present invention is to delete the inconvenience of the above mentioned conventional filing tools, and to provide a filing tool with which it is easy to file sheets and with which ar can easily attach/detach either many sheets or only one sheet or so.
DISCLOSURE OF THE INVENTION
According to the present invention, there is provided a filing tool comprising a magnet and a cover member which is provided with said magnet.
The magnet can be a permanent magnet.
Further, the magnet can be an electromagnet.
Furthermore, the electromagnet preferably includes a slide rheostat.
Furthermore, the electromagnet preferably includes means for switching the magnetically attracting means between excited (magnetized) and non-excited (demagnetized) states.
The word "non-excited state" includes such a state that there remains weak magnetic force. In such a case, the switching means changes the magnetic force of the magnetic attracting means between "excited state" and "non-excited state".
The electromagnet preferably includes an electric cell or battery for exciting the electromagnet, and an on-off switch or the like is preferably used as the switching means which is installed between the cell and the electromagnet.
Further, it is preferable that the electromagnet includes a connecting means for connecting with an AC power source, an the on-off switch is installed between the connecting means and the electromagnet.
It is preferable that the electromagnet is secured to the bracket detachably connected to the cover member.
Further, it is preferable that the cover member is provided with the electromagnet in a manner as to be located at the back of the cover member.
Besides, the cover member is used in a manner as to completely cover both sides of the sheet to be filed, or as to abut one side of the sheet to a board. The cover member is preferably provided with a two-folded sheet with magnetic shield property.
Further, according to the second aspect of the present invention, there is provided a magnetically attractable sheet to be filed in the above mentioned filing tool. The magnetically attractable sheet comprises a sheet, such as paper, plastic sheet or the like, and a magnetically attractable area or band to be easily magnetically attracted and released by a mag
