POSITION INDICATOR AND POSITION INDICATING METHOD
First Claim
Patent Images
1. A position indicator comprising:
- a resonant circuit configured to receive electromagnetic waves transmitted intermittently from a position detection device with a first duration and a second duration, the second duration being shorter than the first duration; and
a load resistance value control circuit configured to control a load resistance of the resonant circuit such that different values of the load resistance are set for the first duration and the second duration, a value of the load resistance set for the second duration being smaller than a value of the load resistance set for the first duration.

Abstract
A position indicator includes a resonant circuit configured to receive electromagnetic waves transmitted intermittently from a position detection device with a first duration and a second duration. The second duration is shorter than the first duration. The position indicator also includes a load resistance value control circuit configured to control a load resistance of the resonant circuit such that different values of the load resistance are set for the first duration and the second duration. A value of the load resistance set for the second duration is smaller than a value of the load resistance set for the first duration.
