Description

  The present invention relates to a writing instrument equipped with a short-range wireless communication function.

  2. Description of the Related Art In recent years, for example, a non-contact IC card having an IC chip has been used for a commuter pass, electronic money, a credit card, or the like as a small wireless device having a short-range wireless communication function as represented by Patent Literature 1, and is used in daily life. It is becoming indispensable.

JP 2000-57290 A Japanese Patent No. 4476686 Japanese Utility Model Registration No. 3104609

Since the IC chip as such a small wireless device is very small, it is highly likely that the IC chip will be lost if it is carried by itself. Therefore, the actual situation is that a card is used as the carrier. However, in recent years, such small wireless devices have been mounted in many mobile phones other than the card type.
Here, as a technique for accommodating an electronic component in a writing instrument, there is a technique in which a memory device with terminals can be accommodated in a barrel of the writing instrument as disclosed in Patent Documents 2 and 3, for example. Writing implements are extremely portable, but by storing such electronic components, they have a function other than the original writing function, so their size is inevitably increased. Is also inconvenient.

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

In order to solve the above-mentioned problem, the short-range wireless communication function-equipped writing instrument 10 according to the present invention is characterized in that a wireless device 50 having a non-power-supplied short-range wireless communication function is attached to a rear portion of the barrel 20. And
Here, as the “wireless device 50 having a non-power supply short-range wireless 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 mounted without impairing portability as a writing instrument.

With such a configuration, when such a wireless device 50 is provided with, for example, a transaction settlement function, it is possible to perform both electronic payment using the wireless device 50 and signing with a writing instrument. Therefore, the procedure at the time of settlement is smoothly performed.
Further, by storing, for example, the product tag information of the writing implement in such a wireless device 50, it is not necessary to attach a barcode or the like to the surface of the barrel 20 for display. Therefore, the design property as a writing instrument can also be improved.

  In the present invention, the wireless device 50 having the non-powered short-range wireless communication function is attached to the rear portion of the barrel 20. However, the method of attachment is not particularly limited. For example, the radio 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 be 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 axial length of the wireless device 50 is adjusted so that the original function of the writing implement is not impaired so that the amount of ink stored in the writing implement is reduced or the weight is unnecessarily increased. It is desirable to keep the length in the direction of 20% or less, preferably 10% or less.

  Alternatively, as a method of further improving the shock resistance of the wireless device 50, there is a method of embedding the wireless device 50 in the rear end of the barrel 20 or in the crown 23 by integral molding such as insert molding. In this case, the material used for integral molding is desirably a soft magnetic material or a non-conductive resin so as not to hinder wireless communication.

Further, in a case where the wireless device 50 is directly attached to the rear end of the barrel 20, the wireless device 50 is provided between the plurality of support columns 26 projecting from the rear end of the barrel 20. It is desirable to be held in. With this configuration, the radio wave emitted by the wireless device 50 can be transmitted from between the support columns 26, and the information carried by the radio wave can be correctly recognized by the reader.
As described above, the wireless 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 a rear end of the barrel 20.

  Then, 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, and the like may be made of metal, and these may be electrically connected to the wireless device 50. Alternatively, the antenna wire may be embedded or wound around the shaft cylinder 20, the crown 23, the clip 40, or the like, and the antenna wire may be 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 increase the reactivity of the wireless device 50 to the reader.

  On the other hand, parts of the shaft cylinder 20, the crown 23, the clip 40, and the like that are not electrically connected are preferably made of a nonmetallic material so as not to interfere with wireless communication. Even when it is necessary to use a metal material, a shape that does not surround the whole is preferable so that radio waves can be transmitted.

  Since the present invention is configured as described above, it becomes possible to mount the short-range wireless communication function on the writing implement without impairing the portability of the writing implement as much as possible.
