no. 1 Embodiment approach

[0055] figure 1 It is a figure which shows the structure diagram (central cross-sectional view) of an example of the position indication module of 1st Embodiment of this invention. exist figure 1 Among them, 11 denotes a substantially disk-shaped dielectric, 12 denotes a first electrode provided on the first surface of the dielectric 11, and 13 denotes a second electrode made of a flexible material. The second electrode 13 is disposed on the second surface side of the dielectric 11 opposite to the first surface with the ring-shaped spacer 14 interposed therebetween. For the second electrode 13 , for example, conductive rubber can be used, or a material obtained by vapor-depositing a conductive substance on one surface of polyimide can be used.

[0056] figure 2 It is a perspective view when the dielectric 11, the spacer 14, and the second electrode 13 are arranged in disassemble. At least the surface 13 a side of the second electrode 13 in contact with the spacer 14 has c...

[0069] [Second Embodiment (Modification of First Embodiment)]

[0070] Figure 5 It is a figure which shows the structure diagram (central sectional view) of an example of the position indication module of 2nd Embodiment, and figure 1 Parts having the same configuration as the position indicating modules of the first embodiment shown are denoted by the same reference numerals. The second embodiment has a lot in common with the first embodiment, so here only figure 1 The different sections are explained.

[0071] 23 represents a coil spring formed of a conductive material, which is basically the same as that used in the first embodiment Figure 4 The coil spring 19 shown is the same, but does not have a portion corresponding to the straightly extending portion, ie, the terminal 19b. The coil spring 23 is inserted into the core frame 20 similarly to the coil spring 19 of the first embodiment, and is in contact with the protruding portion 20 a to be electrically connected.

Abstract

The present invention provides a position indication module for an electrostatic stylus pen, which can easily replace a core body and can detect changes in pen pressure with high precision when lightly touched. The module is a position indication module for an electrostatic stylus that transmits a signal from an electrode of the core, and the position indication module has: a dielectric having a first surface and a second surface opposite to the first surface; The first electrode is arranged on the first surface of the dielectric; the second electrode is arranged opposite to the second surface, and its contact area with the second surface changes according to the external force; the core part has a third electrode at least at the front end. The electrode transmits external force to the second electrode. In addition, the position indication module has a first terminal portion electrically connected to the first electrode, a second terminal portion electrically connected to the second electrode, and a third terminal portion electrically connected to the third electrode. The position indication module further has a fitting portion for electrically connecting the third electrode and the third terminal portion by biasing the core portion to make contact with the third terminal portion.

Description

technical field [0001] The present invention relates to a position indication module and a stylus used for inputting an indication position on a tablet. Background technique [0002] Prior to this application, the applicant has proposed in Patent Document 1 (Japanese Patent Laid-Open No. 2007-164356 ) a position indicator that provides a coil and electrodes in a position indicating portion to obtain a coordinate position on a flat panel. According to this position indicator, by installing a variable capacitance capacitor whose capacitance changes according to the pen pressure, the pen pressure is converted into a digital value and transmitted, so that the pen pressure can be detected with high precision, and a position indicator with excellent operability can be realized. [0003] Regarding variable capacitance capacitors whose capacitance changes according to pen pressure, variable capacitors using dielectrics are disclosed in Patent Document 2 (Japanese Patent Laid-Open No...
