no. 1 Embodiment approach

[0039] figure 1 It is an exploded configuration diagram showing a configuration example of an electronic device incorporating the first embodiment of the position detection device of the present invention. in the figure 1 In an example, the electronic device has a sensor for position detection by electromagnetic induction (hereinafter referred to as a first sensor) to detect an indicator for electromagnetic induction (hereinafter referred to as a first sensor) constituted by a position indicator such as an electronic pen. pointing body), and has the function of detecting the position indicated by a finger and a position indicator (electrostatic pen) through a sensor for position detection (hereinafter referred to as the second sensor) of the electrostatic capacitance method (hereinafter referred to as the second pointing body) is a tablet-type terminal capable of simultaneously detecting position indications of the first and second pointing bodies through two sensors, which...

no. 2 Embodiment approach

[0111] In the first embodiment described above, only the signal level of the transmission signal supplied to the second sensor 40 is controlled in order to reduce fluctuations in the electromagnetic induction first sensor 20 and the position detection circuit 200 .

[0112] However, by controlling the signal level of the transmission signal supplied to the second sensor 40 and controlling the signal level of the electromagnetic induction signal supplied from the first sensor 20 to the electronic pen 23 serving as a position indicator constituting the first indicator, The adverse effect of the transmission signal supplied to the capacitance type second sensor 40 on the electromagnetic induction type position detection circuit 200 can be more effectively reduced.

[0113] The hardware configuration of the position detection device in this second embodiment is the same as that in the above-mentioned first embodiment. Also in this second embodiment, the control circuit 410 of the ...

no. 3 Embodiment approach

[0130] This third embodiment is a modified example of the second embodiment. That is, in the above-mentioned second embodiment, the control circuit 210 of the position detection circuit 200 and the control circuit 410 of the position detection circuit 400 each function as a position indication state discrimination circuit and generate control codes CP1 and CP2 respectively.

[0131] On the other hand, in the third embodiment, a control code generation circuit including a position indication status determination circuit is provided separately from the position detection circuit 200 and the position detection circuit 400 to reduce the processing load on the control circuit 210 and the control circuit 410 .

[0132] Figure 9 Main parts of an example hardware configuration of the position detection circuit of the electronic device 10 according to the third embodiment are shown. It has the same structure as the above-mentioned 1st Embodiment and 2nd Embodiment except the part sho...

Abstract

A position detector and a position detection method are discloses. The position detector includes a first sensor for detecting a position indicated by a first indicator by electromagnetic induction and a second sensor for detecting a position indicated by a second indicator by a detection method other than electromagnetic induction. The position detector reduces adverse effects of the transmission signal supplied to the first and / or second sensor on the electromagnetic induction position detection circuit. The position indication state of the first and second indicators is determined based on a signal output from the first sensor according to the position indication by the first indicator on the first sensor and a signal output from the second sensor according to the position indication by the second indicator on the second sensor. According to the determination results of the position indication state, the level of the transmission signal provided to the first and / or second sensor to detect the position indication by the second indicator is controlled.

Description

technical field [0001] The present invention relates to a position detection device comprising a first sensor for detecting a position indication of a first pointer by electromagnetic induction, and a second sensor for detecting a position indication of a second pointer by a detection method other than electromagnetic induction. The sensor can simultaneously detect position indications of the first pointer and the second pointer. Background technique [0002] There is known a position detection device that detects a position indicated by a pointing body such as a finger or a pen. As a position detection method employed in this position detection device, there are various methods such as a resistive film method, an electromagnetic induction method, and an electrostatic capacitance method. [0003] Among them, an electromagnetic induction type position detection device is constituted by a sensor and a position indicator as an indicator, as disclosed in, for example, Patent Do...
