Writing instrument with built-in memory medium

Abstract

To provide a writing instrument that can stably and securely house a passive communication medium inside without compromising the appearance or strength of the writing instrument. [Solution] The shaft body has a double structure consisting of an outer layer member 2 and an inner layer member 3, with a flat plate-shaped passive communication medium 4 placed between the two members. The communication medium is completely fixed to the outer layer member and the inner layer member via an adhesive layer 5, and the shaft body is a non-disassemblable structure. This suppresses misalignment and detachment of the communication medium and ensures communication stability without compromising the appearance.

Description

[0005] , , ,

[0004]

[0001] The present invention relates to a writing instrument, and particularly to a writing instrument having a structure in which a passive communication medium is fixedly arranged inside.

Background Art

[0002] Conventional writing instruments generally have a structure mainly for writing, and the shaft body is formed of materials such as wood, resin, and metal. In recent years, with the progress of the electronicization of information, technologies for incorporating communication media into various articles are known. However, regarding the structure for stably fixedly arranging a passive communication medium inside a writing instrument without impairing the appearance, there have not been many that have been sufficiently studied.

Summary of the Invention

[0006] According to this invention, a passive communication medium is placed between a double-layered shaft body consisting of an outer layer member and an inner layer member, and this is completely fixed with an adhesive layer, while the shaft body is made non-disassemblable. This makes it possible to suppress displacement, rotation, and detachment of the communication medium. Furthermore, since the communication medium is not exposed to the outside, the appearance of the writing instrument is not compromised, and by incorporating a radio wave absorption prevention component, improved communication stability can be expected. Furthermore, by adopting a non-disassemblable structure, it becomes difficult to remove or replace the communication medium, thereby maintaining structural stability. Embodiment

[0007] The embodiments of the present invention will be described below with reference to the drawings. Note that this embodiment is just one example of the present invention, and the present invention is not limited thereto. Description of the overall structure

[0008] Figure 1 is an external view of the writing instrument of the present invention, and Figure 2 is an axial cross-sectional view. The writing instrument 1 comprises a shaft body 10, which has a double structure consisting of an outer layer member 2 and an inner layer member 3. The material of the outer layer member 2 and the inner layer member 3 is not limited to wood, but can be stone, ceramic, resin, metal or other materials. Arrangement structure of passive communication medium

[0009] As shown in Figure 2, a flat, passive communication medium 4 is placed between the outer layer member 2 and the inner layer member 3. The passive communication medium 4 is completely fixed to both the outer layer member 2 and the inner layer member 3 via an adhesive layer 5. Furthermore, the fixing method is not limited to full fixing with an adhesive layer; partial fixing, press-fitting, resin sealing, or other similar methods may also be used. (Radio wave absorption prevention member)

[0010] The passive communication medium 4 may be configured to include a radio wave absorption prevention member 6. This reduces the effect of radio wave attenuation caused by metal members, etc. Non-disassemblable structure

[0011] The shaft body 10 has a non-disassemblable structure, and the outer layer member 2 and inner layer member 3 are integrally formed. This makes it difficult to remove or replace the passive communication medium 4 and ensures structural stability.

[0012] A two-dimensional code 7 may be formed on the outer surface of the outer layer member 2. The two-dimensional code 7 may be formed by engraving, laser processing, printing, maki-e, etching, or other similar methods. Writing method

[0013] This writing instrument 1 is manufactured with a dedicated structure for either a ballpoint pen, a fountain pen, or a mechanical pencil. The writing method is determined at the time of manufacture and can be configured so that it cannot be changed to another method during use. [Brief explanation of the drawing]
