Abstract

An inexpensively-produced operating tool to which information about the direction of the operating tool or various kinds of identification information can be provided, and in which a switch can be provided. An operating tool (100), which is placed on the detection plane of a conductor detector capable of detecting a conductor by detecting a change in coupling coefficient of loop coil groups crossing each other, comprises a plurality of conductor pieces (102). The conductor piece has, for example, a circular shape, a rectangular shape, or a ring shape. At least a part of the plurality of conductor pieces may be arranged in a predetermined pattern such that the conductor detector can detect the direction of the operating tool.

Claims

1. An operating tool placed on a detection plane of a conductor detector that can detect a conductor by detecting a change in coupling coefficient between loop coil groups crossing each other, said operating tool comprising a plurality of conductor pieces that can be detected by the conductor detector, at least some of the plurality of conductor pieces being arranged in a predetermined pattern that allows the operating tool to have identification information.

2. The operating tool according to claim 1, in which at least one of the plurality of conductor pieces has a circular shape, a rectangular shape, or a ring shape.

3. The operating tool according to claim 1, in which at least one of the plurality of conductor pieces is a loop coil having switch for opening/closing the loop of the loop coil.

4. The operating tool according to claim 1, in which at least three of the plurality of conductor pieces are arranged in a pattern that allows the conductor detector to detect the direction of the operating tool.

5. The operating tool according to claim 1, in which at least one of the plurality of conductor pieces has a shape that allows the conductor detector to detect the direction of the operating tool.

6. The operating tool according to claim 1, which further comprises a rotating member which is rotated about an axis perpendicular to the detection plane, wherein at least one of the plurality of conductor pieces is arranged on the rotating member.

7. The operating tool according to claim 1, in which the operating tool has a card shape, and the plurality of conductor pieces are each made of a thin film.

8. The operating tool according to claim 1, in which the plurality of conductor pieces each have a width equal to or slightly larger than the width of each of the loop coil group of the conductor detector.

9. (canceled)
