JPH0516394U - Structure of electric eraser - Google Patents

Abstract

(57) [Abstract] [Purpose] The present invention is to use a colorant that absorbs the special light of a halogen lamp and causes a chemical reaction to become colorless, so that a document copied with a toner for copying or a word processor is used. When proofreading a document printed with the printing ribbon or a document written with a ball-point pen, you can easily erase only the characters and parts you want to erase, and even if you erase it, the document The purpose is to allow documents to be reused many times without getting dirty, thin, or torn. [Structure] To describe the structure, a space for accommodating a battery 8 is provided in a case 1, and a switch 2 is provided on a side surface. At the tip of the case 1, a socket 3 having a reflecting mirror 4 at the tip is attached, and a halogen lamp 5 is attached. The optical tube 6 is inserted and attached around the socket 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to the structure of an electric eraser.

[0002]

[Prior Art]

 A conventional electric eraser is called an electric eraser, and a cylindrical eraser is rotated by a small motor to erase characters.

[0003]

[Problems to be solved by the device]

 The conventional technique has the following drawbacks. When erasing a copied document or a document printed with a word processor with a conventional electric eraser, it must be erased with a sand eraser, so the erased mark becomes dirty or disappears well. It was very uneconomical to use new paper every time, because the paper that was erased was thin or the erased part became thin, and the letters that were written later were blurred or the paper was torn. When you want to erase one character or one part, the eraser is rotating, so it may be possible to erase even the necessary characters and parts around it, which is very inconvenient.

[0004]

[Means for solving the problem]

 A space for accommodating the battery (8) is provided in the case (1), and a switch (2) is provided on the side surface. Attach the socket (3) and the halogen lamp (5) to the tip of the case (1). The reflecting mirror (4) is provided at the tip of the socket (3), and the optical tube (6) is inserted around it and attached. The structure of the electric eraser with the above configuration.

[0005]

[Action]

 To use, hold the case (1) in your hand, cover the tip of the light guide tube (6) with the letter you want to erase, and press the switch (2) with your finger to turn off the light emitted from the halogen lamp (5). Hit

[0006]

【Example】

 (A) Provide a space in the case (1) for accommodating the battery (8) and a switch (2) on the side surface. (B) At the tip of the case (1), attach the socket (3) having the reflecting mirror (4) at the tip, and attach the halogen lamp (5). (C) Insert the optical tube (6) around the socket (3) and attach it. (D) Even if a convex lens is provided in the light guide tube (6), the same effect can be obtained. (E) The same effect can be obtained by inserting a dustproof transparent glass plate or a plastic plate into the light guide tube (6). (F) The same effect can be obtained by using a 100-volt power supply without using a battery. (G) Even if the glass surface of the halogen lamp (5) is mirror-treated instead of the reflecting mirror (4), the same effect can be obtained.

[0007]

[Effect of the device]

 Since the present invention is configured as described above, it is printed with a copy toner that uses a coloring agent that absorbs near infrared rays of a halogen lamp and erases characters, and a printing ribbon of a word processor. If you use it when you want to calibrate a document or a document written with a ballpoint pen or reuse a used document, the printed characters will absorb the near infrared rays of the halogen lamp and cause a chemical reaction to erase the characters. , Like the conventional electric eraser, the erased part of the paper does not become thin, the characters written on the marks do not smear, get dirty, or break, and you can calibrate it many times and re-install the paper. Since it can be used, it has a very economical effect to contribute to solving environmental problems. Also, when you want to erase one character or one part, you can easily replace and replace the light guide tube with a different size or shape of the cross section of the tip of the light guide tube according to the size of the character you want to erase. A light tube that prevents scattering and concentrates light on one character or part can be easily erased without erasing necessary surrounding characters and parts, which is very convenient when calibrating small parts. .
