no. 1 Embodiment approach

[0087] figure 1 The shown coil device 2 for an electronic pen according to one embodiment of the present invention is mounted inside the electronic pen, and uses the position information of the electronic pen together with the change information of the electronic pen, for example, about the change information applied to the electronic pen. Information such as pressure or displacement of the electronic pen is transmitted to a part of the device such as an input display screen such as a tablet for use.

[0088] First, in this embodiment, the principle of detecting the position information of the electronic pen and the use state of the electronic pen will be briefly described.

[0089] The tuning circuit of the electronic pen (including figure 1 The shown coil part 20) receives the radio wave and is excited when a radio wave of a predetermined tuning frequency, for example, frequency f0 is transmitted from an input display screen such as an input panel (not shown in the figure),...

no. 2 Embodiment approach

[0136] In this embodiment, if Figure 7 As shown, a pair of first terminal 30a1 and a part of second terminal 30b1 also serve as the wire winding guide 10a, and configure the coil device 2a similarly to the first embodiment. Hereinafter, different parts will be described in detail, and descriptions of overlapping parts will be partially omitted.

[0137] Such as Figure 8 As shown, the first terminal 30a1 and the second terminal 30b1 are composed of two metal terminals that are completely separated in the Y-axis direction, and are formed by bending a metal sheet that is press-formed from a metal plate.

[0138] The first terminal 30a1 has a cylindrical first covering piece 31a. The first covering sheet 31a, such as Figure 7 As shown, it is formed into a shape that covers the lower portion of the outer peripheral surface near the base end 4b of the core body 6 by approximately 1 / 6 to 1 / 3 of the circumference (preferably approximately 1 / 4 of the circumference). The first co...

no. 3 Embodiment approach

[0161] In this embodiment, if Figure 11 As shown, except that a metal terminal is not attached to the wire winding guide 10b, the coil device 2b is configured in the same manner as in the first embodiment. Hereinafter, different parts will be described in detail, and descriptions of overlapping parts will be partially omitted.

[0162] Such as Figure 11 As shown, in the winding guide 10b of this embodiment, there is no image 3 Terminal mounting tab 18 is shown. The outer peripheral cover 12 is provided with the auxiliary protruding piece 19, and the notched common winding passage 13 and the individual winding passages 13a, 13b are provided on the opposite side in the Z-axis direction, as in the first embodiment. Each of the individual winding passages 13a, 13b is provided with a plurality of preliminary fixing parts 13d.

[0163] In addition, the first lead part 22a and the second lead part 22b of the winding wire 22 extend from the individual winding passages 13a, 13b ...

Abstract

The present invention provides an electronic pen coil device in which an automatic winding operation of a wire is easy and a small diameter of an electronic pen can be obtained. On the outer periphery of a core (4), a wire guide (10) is disposed in the vicinity of a base end (4b). The wire guide (10) has a winding start position restricing portion (12a) for restricting the winding start position of a wire (22) and a winding end position restricing portion (12b) configured to be separated in the circumferential direction with respect to the winding start position restricting portion (12a) and for restricting the winding end position of the wire (22) at a position (x1) in which the winding start position restricting portion (12a) is introduced toward the base end (4b) in the reel direction.

Description

technical field [0001] The present invention relates to a coil device for an electronic pen incorporated in, for example, an electronic pen for inputting desired information into a computer. Background technique [0002] Inside an electronic pen for inputting desired information into a computer, for example, as disclosed in Patent Document 1, there is a built-in coil device in which a wire is wound around the outer circumference of a core such as a ferrite core. Case. In an electronic pen incorporating such a coil device, a structure that facilitates automatic winding of the winding wire is required. [0003] Especially recently, there is a case where the diameter of the electronic pen is required to be reduced. For example, in the existing coil device for the electronic pen described in Patent Document 1, the automatic winding operation of the winding wire is not easy, and the coil device and the circuit Wiring on the substrate becomes complicated, making it difficult to ...
