JP, 2000-57290, A Japanese Patent No. 4476686 Utility model registration No. 3104609

Since such an IC chip as a small-sized wireless device is very small, it is highly likely that it will be lost if it is carried around by itself. Therefore, the actual situation is that the carrier is in the form of a card. However, in addition to the card form, in recent years, many small-sized radios have been installed in many mobile phones.
Here, as a technique for accommodating an electronic component in a writing instrument, there is a technique in which a terminal-equipped memory device can be accommodated in a shaft cylinder of the writing instrument as disclosed in Patent Documents 2 and 3, for example. Writing instruments are very portable, but by containing such electronic components, the size of the writing instrument is inevitably increased by having functions other than the original writing function, which hinders portability and makes it a writing instrument. The usability of will be worse.

  Therefore, an object of the present invention is to provide a writing instrument with a short-distance wireless communication function without hindering the portability of the writing instrument as much as possible.

In order to solve the above problems, the writing instrument 10 with a short-range wireless communication function according to the present invention is characterized in that a wireless device 50 having a non-power source short-range wireless communication function is attached to the rear part of the barrel 20. And
Here, as the "radio device 50 having a non-power source near field communication function", for example, an IC chip used for a so-called non-contact IC card can be used. By attaching such a wireless device 50 to the rear end of the barrel 20, a short-range wireless communication function can be installed without impairing portability as a writing instrument.

With such a configuration, when such a wireless device 50 is provided with a transaction settlement function, for example, both electronic settlement by the wireless device 50 and signature by a writing instrument can be performed. Therefore, the procedure at the time of settlement can be smoothly performed.
In addition, for example, by storing the product tag information of the writing instrument in such a wireless device 50, it becomes unnecessary to attach a bar code or the like to the surface of the barrel 20 and display it. Therefore, the designability as a writing instrument can also be improved.

  In the present invention, the wireless device 50 having a non-power source short-range wireless communication function is attached to the rear portion of the barrel 20, but the attaching method is not particularly limited. For example, the wireless device 50 may be directly attached to the rear end of the barrel 20. In such a case, it is more preferable that the wireless device 50 is covered with a crown 23 attached to the rear end of the barrel 20. By doing so, the shock resistance of the wireless device 50 can be improved. Here, the length of the wireless device 50 in the axial direction is set so that the amount of ink contained in the writing instrument is reduced or the weight is unnecessarily increased, so that the original function of the writing instrument is not impaired. It is desirable to keep the length to 20% or less, preferably 10% or less.

  Alternatively, as a method of further increasing the shock resistance of the wireless device 50, there is a method of embedding the wireless device 50 by integrally molding such as insert molding in the rear end of the shaft cylinder 20 or in the crown 23. In that case, a soft magnetic material or a non-conductive resin is desirable as the material used for the integral molding so as not to disturb the wireless communication.

Further, in the case where the wireless device 50 is directly attached to the rear end of the shaft cylinder 20, the wireless device 50 is provided between the plurality of support columns 26 protruding from the rear end of the shaft cylinder 20. It is desirable to be held in. With this configuration, the radio wave emitted by the wireless device 50 can be transmitted through the space between the support columns 26, and the reader can correctly recognize the information carried by the radio wave.
Note that, as described above, the radio device 50 may be directly attached to the rear end of the barrel 20, but may be indirectly attached. For example, the wireless device 50 may be housed inside a clip 40 attached to the rear end of the barrel 20.

  The barrel 20 may have an antenna function, and the wireless device 50 may be electrically connected to the barrel 20. For example, the shaft cylinder 20, the crown 23, the clip 40, or the like may be made of metal so that they are electrically connected to the wireless device 50. In addition, the antenna wire may be embedded or wound around the barrel 20, the crown 23, the clip 40, or the like so that the antenna wire is electrically connected to the wireless device 50. Good. In any case, by providing such an antenna function on the outer surface of the writing instrument, it becomes possible to enhance the responsiveness of the wireless device 50 to the reader.

  On the other hand, of the shaft cylinder 20, the crown 23, the clip 40, and the like that are not electrically connected, it is desirable that parts near the wireless device 50 are made of a non-metallic material so as not to interfere with wireless communication. Even when it is necessary to use a metal material, it is preferable that the whole shape is not enclosed so that radio waves can be transmitted.

  Since the present invention is configured as described above, it becomes possible to equip a writing instrument with a short-range wireless communication function without impairing the portability of the writing instrument as much as possible.
