[0046] [Explanation of the appearance of the position detection device]

[0047] figure 1 It is an external view showing an embodiment of the position detecting device of the present invention. The position detection device 10 of the present embodiment includes a pen-shaped position indicator and a digital tablet.

[0048]The position indicator is used on the position detection area 2a of the tablet. In this position detection area 2a, the indicated position (coordinates) of the position indicator can be detected. In addition, a side bar (hereinafter referred to as a slider) 1cb that can move vertically along the longitudinal direction of the position indicator is p...

[0174] Next, a second embodiment of the present invention will be described. In the second embodiment, an example is shown in which the rotation angle of the position indicator with the axis perpendicular to the tablet surface can be obtained. The applicant has already disclosed such a position detection device in Japanese Patent Application Laid-Open No. 8-030374. The present embodiment shows an example in which the rotation angle of the position indicator can be obtained even on a tablet surface using a loop coil formed of a high-resistance ITO film or the like by adding improvement thereto. In this embodiment, the tablet is formed with Figure 4 and Figure 5 The first embodiment shown is of the same construction as the tablet used.

[0207] Next, a third embodiment of the present invention will be described. In this embodiment, two position indicating parts (pen side and eraser side) are provided on the position indicator to detect the direction of the position indicator toward the tablet surface.

[0208] The position indicator of this embodiment does not hold a variety of information like the first embodiment or the second embodiment, but has only pen pressure information on the pen side or the eraser side.

[0210] Figure 14 is a cross-sectional view showing the structure of the position indicator of this embodiment. This embodiment also forms the position indicator in the shape of a pen, and the front end portion of the core 1b protrudes from the main body 1a. It is operated so that the front end portion of the core body 1b comes into contact with the tablet surface. 62 is a hollow coil, and the core 1b penetrates through the coil 62 . In addition, a var...

Abstract

A position detector includes a position indicator including a power source and configured to intermittently transmit a position indication signal to a tablet at a predetermined timing; and the tablet configured to detect a position on its surface pointed to by the position indicator by receiving the position indication signal. The position indicator further includes an information storing section configured to store multiple types of information; a control signal receiving circuitry configured to receive a control signal transmitted from the tablet; an information selecting circuitry configured to select one type of information from among the multiple types of information stored in the information storing section in accordance with a content of the control signal; and an information transmitting circuitry configured to transmit the one type of information selected by the information selecting circuitry to the tablet.

Description

technical field [0001] The present invention relates to a position indicator and a position detection device capable of detecting, for example, various information including a unique ID stored on the side of the position indicator that detects the position of the position indicator, or a pen obtained from the operation of the position indicator. Press and other information. Background technique [0002] Conventionally, a position detection device called a pen tablet has been developed as one of pointers used for photo editing, illustration creation, etc. on a computer device. A tablet generally includes a generally flat-shaped position detection unit (hereinafter referred to as a tablet) and a pen-shaped dedicated position indicator for a user to operate on the tablet. [0003] As such a position detection device, there is a device that detects, by electromagnetic induction, a reflected signal generated by a resonant circuit provided on the position indicator and resonating...
