[0017] the housing has a deformation portion for preventing the electronic pen from rolling.

[0018] According to the electronic pen, since the housing itself has the deformation portion for preventing the electronic pen from rolling, the electronic pen can be prevented from rolling and falling from a desk or the like with a simple configuration.

[0033] Embodiments of the electronic pen of the present application will be described below with reference to the accompanying drawings. In addition, in the electronic pen (position indicator) and position detection device, there are an electromagnetic induction method (EMR (Electro Magnetic Resonance technology) method) and an active electrostatic coupling method (AES (Active Electrostatic) method).

[0034] In the electromagnetic induction method, the position detection device is provided with a sensor portion in which a plurality of annular coils are arranged in the X-axis direction and the Y-axis direction. Furthermore, the transmission period in which power is supplied to the plurality of annular coils of the sensor portion in turn to generate a magnetic field and the reception period in which the supply of power is stopped and a magnetic field from the outside is received are alternately set. The corresponding electronic pen is provided with a resonance circuit composed of a coil and a capacitor, and according to the magnetic field from the sensor portion, a signal is generated by the flow of current in the coil, and the signal in which the pen pressure information is contained is transmitted to the position detection sensor. In the reception period, the position detection device receives the signal and detects the indication position and the pen pressure of the electronic pen.

[0035] In the case of the active electrostatic coupling method, the electronic pen transmits the signal from the oscillation circuit mounted on the electronic pen in which the pen pressure information is also contained, and the signal is received by the position detection device, and the indication position and the pen pressure are detected.

[0036] The electronic pen of the present application can be used as an electronic pen for the electromagnetic induction method and an electronic pen for the active electrostatic coupling method.

[0037] Figure 1 is a diagram for explaining the entire electronic pen of the present application. Figure 2 is a diagram for explaining the deformation portion of the electronic pen of the present application.

[0038] Referring to Figure 1 and Figure 2 , the electronic pen indicates the position to the position detection device, and is provided with: a housing having an opening portion at the front end portion on the pen tip side; and a core body passing through the opening portion of the housing, the housing having a deformation portion for preventing the roll of the electronic pen.

[0039] Since the housing itself has the deformation portion for preventing the roll of the electronic pen, the roll of the electronic pen can be prevented with a simple configuration, and the electronic pen can be prevented from falling from a desk or the like.

[0040] When the housing is molded, the deformation portion is integrally molded.

[0041] The deformation portion is a convex portion. Since the deformation portion is a convex portion, the roll of the electronic pen can be prevented with a simple configuration, and the electronic pen can be prevented from falling from a desk or the like.

[0042] The deformation portion is located at the rear end portion of the electronic pen. Since the deformation portion is located at the rear end portion of the electronic pen, the deformation portion is provided at a position that does not interfere with the user's holding, thereby avoiding affecting the user's holding.

[0043] The outer shell of the electronic pen is gradually deformed into the shape of the deformation portion in a direction from the front end portion toward the rear end portion from the front end portion. Since the outer shell of the electronic pen is gradually deformed into the shape of the deformation portion in a direction from the front end portion toward the rear end portion from the front end portion, the appearance is beautiful.

[0044] A charging port for charging the electronic pen is provided at the side wall of the rear end portion of the outer shell, and the deformation portion is provided at a position avoiding the charging port so as not to interfere with charging. Since the charging port for charging the electronic pen is provided at the side wall of the rear end portion of the outer shell, and the deformation portion is provided at a position avoiding the charging port so as not to interfere with charging, the rolling of the electronic pen can be prevented in a manner that does not interfere with charging, and the electronic pen can be prevented from falling from a desk or the like.

[0045] The electronic pen further includes a holder provided inside the outer shell, a battery is provided inside the holder, the deformation portion is in the shape of a water droplet having an apex, a charging port for charging the battery is provided at the rear end portion of the outer shell, and the charging port is provided at a position avoiding the apex.

[0046] Figure 2 A-A of FIG. 1 ′ The cross section is at the charging port, such as A-A ′ As shown in the cross section, the water droplet shape includes a circular arc portion, and the charging port is provided at the circular arc portion.

[0047] Figure 2 The arrow in FIG. 1 indicates the pressing direction, Figure 2 The cross-sectional view at the lower right in FIG. 1 is 90 degrees different from the cross-sectional view above it in terms of the angle at which the deformation portion protrudes.

[0048] Since the electronic pen further includes a holder 3 provided inside the outer shell 2, a battery is provided inside the holder 3, the deformation portion is in the shape of a water droplet having an apex, a charging port for charging the battery is provided at the rear end portion 1 of the outer shell 2, and the charging port is provided at a position avoiding the apex, the charging port for insertion between a USB-C or the like and a charging cable can be connected without a gap, and stable charging can be performed.

[0049] In Figure 2 A case in which the charging port is provided at a position corresponding to the apex of the water droplet shape is shown at the lower right in FIG. 1. In this case, since there is a gap between the outer shell 2 and the holder inside the outer shell 2, it is equivalent to providing a charging port at a position corresponding to the gap, and stable charging cannot be performed.

[0050] Note that, in the above embodiment, a case where the deformation portion is a convex portion is described, but the deformation portion can also be a shape other than a convex portion, as long as it can achieve avoidance of the electronic pen from rolling.

[0051] Note that, in the above embodiment, a case where the deformation portion is a convex portion is described, but the deformation portion can also be a shape other than a convex portion, as long as it can achieve avoidance of the electronic pen from rolling.

[0052] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included in the protection scope of the present application.
