The pen body 10 has an outer shape that gradually decreases in diameter as it goes from the intermediate portion to both ends, and is formed so as to become familiar with the hand when the user grips it. The pen body 10 is provided with an indicator unit 24. The indicator unit 24 includes an LED (Light Emitting Diode), a liquid crystal panel, and the like, and displays, for example, a battery remaining amount display.
In addition to the writing function similar to that of a normal ballpoint pen, the pen body 10 configured in this way reads and stores the written content, for example, optically, as will be described later, and an external computer device as necessary. It has an electronic function to communicate.

The cap 30 includes a cap body 31 for covering the pen tip 12 (see FIG. 2) of the pen body 10 and a notch (notch shape) formed by cutting out a part of the edge 31a of the cap body 31. Part, strap passing part) 32, and a clip 34 that is attached to the outer surface 31c of the cap body 31 and holds paper or the like. The notch 32 is provided at a position in the longitudinal direction B of the clip 34.
When the pen main body 10 is not used, as shown in FIG. 1, the cap 30 covers the one end portion 10a to prevent the pen ink from drying and to protect the pen tip 12. When the pen body 10 is used, as shown in FIG. 2, the cap 30 is held by the pen body 10 by removing the cap 30 and fully engaging the other end portion 10b. Loss can be prevented.

  Here, about the attachment of the cap 30 and the pen main body 10, directionality is given. That is, if the cap 30 and the pen body 10 are not in a certain specific positional relationship, the inner surface shape of the cap 30, the one end 10 a of the pen body 10, etc. An outer surface shape of the end portion 10b is formed. Specifically, as shown in FIGS. 1 and 2, when the cap 30 is inserted into the one end 10 a or the other end 10 b of the pen body 10, the notch 32 is positioned on the indicator 24 side. To be done. In other words, when the use of the pen main body 10 is finished, the cap 30 is inserted into the one end portion 10a of the pen main body 10 so that the cap 30 is in a direction to be received in the concave portion 11a of the pen main body 10 to be engaged and held.

As shown in FIG. 3, the cap 30 has a thin portion (strap passage portion) 33 in which an inclined surface (inclined portion) 33 a is provided on the inner surface 31 b of the cap body 31 in the notch portion 32. The inclined surface 33 a of the thin portion 33 extends in the direction of arrow B, which is the longitudinal direction of the clip 34, so that the thickness decreases toward the notch portion 32.
The cap 30 includes a magnet (a component corresponding to an electronic device) 35 attached to the inner surface 31 b of the cap body 31. The magnet 35 is a component that corresponds to a switch mechanism (not shown) provided inside the pen body 10. That is, when the cap 30 is removed from the pen body 10, the switch is turned on to turn on the power, and when the pen body 10 is attached to the cap 30, the switch is turned off. Thereby, the user's feeling of use can be improved and unnecessary power consumption due to forgetting to switch off can be suppressed.

  Further, the magnet 35 is located on the opposite side of the clip 34 in the cross section of the cap 30. Therefore, when the cap 30 is inserted into the other end portion 10 b of the pen body 10, the magnet 35 can be prevented from coming into contact with the strap 40 attached to the strap hole 19 of the pen body 10. That is, as the strap 40, those manufactured from various materials exist in the world, and a strap including a metal part is actually sold and used. For this reason, it is preferable to prevent the magnet 35 corresponding to the electronic device from contacting the strap 40 as much as possible. In the present embodiment, when the cap 30 is inserted into the other end portion 10 b of the pen body 10, the strap 40 is guided by the notch 32, thereby reducing the chance that the magnet 35 contacts the strap 40. Is possible.

  Here, the edge shape of the notch part 32 formed in the cap 30 is a substantially chevron shape formed by a gentle curve, and is formed so as to be connected from the edge part 31a by a continuous curve. Since the cap 30 has such a notch 32, the cap 30 is sufficiently attached to the other end 10 b of the pen body 10, as will be described later, even when the strap 40 is attached to the strap hole 19. It becomes possible to insert. The action of the notch 32 is further increased by the thin portion 33 (see FIG. 3) of the cap 30. This will also be described later.

When the edge shape of the notch 32 is viewed from another point of view, the strap 40 attached to the pen body 10 is guided as the user inserts the cap 30 into the other end 10b of the pen body 10. The cap 30 has the function to perform.
Further, when the edge shape of the notch 32 is viewed from another viewpoint, as shown in FIG. 3, the notch 32 is large up to the vicinity of the portion of the cap main body 31 with which the holding end 34 a of the clip 34 abuts. It is cut out. Therefore, when the user wants to hold the paper or the like to be clamped by the clip 34, the cap 30 has a function of guiding the paper or the like to the clip 34 by the edge shape of the notch 32.
Furthermore, when the edge shape of the notch 32 is viewed from another viewpoint, as shown in FIG. 2, when the cap 30 is held by the pen body 10, up to a portion adjacent to the clamping side end 34 a of the clip 34. A part of the outer peripheral surface of the pen body 10 is exposed. For this reason, even if the cap 30 is sufficiently inserted into the other end portion 10b of the pen body 10, the indicator portion 24 of the pen body 10 is not hidden or the portion to be hidden is reduced. Therefore, even when the cap 30 is engaged and held with the other end portion 10 b of the pen body 10, the user can visually recognize the content displayed by the indicator unit 24.

  FIG. 4 is a partial cross-sectional view for explaining the structure of the pen body 10. The exterior case 11 of the pen body 10 includes a pen core 13 that stores ink ejected from the pen tip 12, and a pen pressure sensor unit that detects a user's writing pressure transmitted through the pen tip 12 and the pen core 13. 14. Further, for example, an optical module 15 that reads a dot pattern provided by Anoto (trademark) and a portion drawn by the pen tip 12 is provided. Furthermore, a terminal 16 for supplying power for charging the pen body 10 and communicating with an external computer is provided. The terminal 16 is configured to be connectable to the terminal of the cap 30 when the pen body 10 is inserted into the cap 30.

  Further, the pen body 10 includes a battery 17 made of, for example, a lithium ion battery, which becomes a power source of the pen body 10 by discharging after charging, and a vibrator 18 that vibrates when the power is turned on, for example. Furthermore, a substrate 20 on which various integrated circuits and electronic components are mounted is provided inside the pen body 10. An optical module 15 is mounted on the substrate 20, and a processor (information processing means, electronic device) 21 that controls the entire pen body 10 and information read by the optical module 15 (written contents and position) For example, Bluetooth (trademark) or the like and a wireless communication module 23 for performing wireless communication.

FIG. 5 is a longitudinal sectional view of the pen body 10 with the cap 30 held at the other end 10b, and FIG. 6 is a sectional view (transverse sectional view) taken along line VI-VI in FIG.
As shown in FIGS. 5 and 6, the string-like member 41 of the strap 40 is guided from between the cap 30 and the pen body 10 to the outside of the cap 30 by the notch portion 32 and the thin portion 33 provided in the cap 30. A space S is formed. For this reason, even when the cap 30 is inserted into the other end portion 10b of the pen body 10 in a state where the strap 40 is attached to the strap hole 19 of the pen body 10, the string-like member 41 of the strap 40 remains in the space. It is located in S and it can avoid interfering with the pen main body 10 and the cap 30. FIG. Thus, since the influence of the strap or the like can be reduced, the cap 30 can be inserted sufficiently deep into the other end portion 10b of the pen main body 10, and the cap 30 can be held and engaged more reliably. .

Here, by providing the notch 32 in the cap 30, the contact distance between the pen body 10 and the cap 30 is shortened. However, since the notch 32 is partially formed, the cap 30 is the pen body. It is possible to ensure a sufficient holding force to hold the other end 10b of the ten. More specifically, the cap 30 inserted into the other end portion 10b of the pen body 10 is easily bent outward by the notch 32, and the contact area between the pen body 10 and the cap 30 is increased, so that the It becomes possible to hold. That is, the notch 32 of the cap 30 performs a slit-like function.
In the present embodiment, the cap 30 is formed with a thin portion 33 in addition to the notch portion 32. This is because the notched portion 32 allows the string-like member 41 of the strap 40 to easily escape, but the notched portion 32 alone may be insufficient. Is useful. In addition, it may be advantageous to form the escape path of the string-like member 41 of the strap 40 with only the thin portion 33.

As described above, in the present embodiment, when the cap 30 is inserted into the other end portion 10b of the pen body 10, the notch 32 is formed in the cap 30 so that the influence of the strap 40 or the like is reduced. By forming the thin portion 33 in which the thickness of 30 is partially reduced, the contact distance between the pen body 10 and the cap 30 is shortened, so that the strap 40 or the like attached to the other end portion 10b of the pen body 10 is attached. The cap 30 can be easily and sufficiently inserted into the other end portion 10b of the pen body 10 without being affected.
Further, even when the string-like member 41 of the strap 40 is short and the small article (not shown) as an accessory is attached to the string-like member 41 by the notch portion 32 of the cap 30, It is possible to avoid the article from being positioned between the cap 30 and the pen body 10, and it becomes possible to position a small article (not shown) outside the cap 30.
In the present embodiment, the indicator unit 24 is provided in the pen body 10, but a configuration without the indicator unit 24 is also conceivable.

7 is a cross-sectional view of a state in which the cap 30 is held on the other end portion 10b of the pen body 10 according to another embodiment, corresponding to FIG. 6 of the cross-sectional view taken along line VI-VI in FIG. is there.
As shown in FIG. 7, in this embodiment, instead of forming the notch portion 32 and the thin portion 33 in the cap 30, a groove portion 25 as a strap passage portion is formed on the indicator portion 24 side of the pen body 10. ing. The groove 25 extends in the direction connecting the one end 10a and the other end 10b of the pen body 10, that is, in the longitudinal direction A of the pen body 10 (see FIG. 1 or FIG. 2, the direction perpendicular to the paper surface in FIG. 7). . The groove 25 provided in the pen body 10 forms a space for guiding the string-like member 41 of the strap 40 from between the cap 30 and the pen body 10 to the outside of the cap 30. By passing the string-like member 41 of the strap 40 through this space, the cap 30 can be sufficiently inserted into the other end portion 10b of the pen body 10 with less influence of the strap.
Naturally, it is conceivable to form the notch 32 and the thin portion 33 in the cap 30 (see FIG. 6) and the groove 25 in the pen body 10 (see FIG. 7). In addition, it is thought that the structure (refer FIG. 6) which forms the notch part 32 and the thin part 33 improves a user's usability rather than the structure (refer FIG. 7) which forms only the groove part 25. FIG. That is, it is expected that it takes time and effort for the user to align the strap 40 and the like with the groove 25 of the pen body 10.
