Abstract:
A position detection apparatus includes a sensor, and a controller that detects a position of a first position indicator and a position of a second position indicator through the sensor. The controller continues detecting the position of the first position indicator and halts detecting the position of the second position indicator after a state in which the positions of the first position indicator and the second position indicator are not detected changes to a state in which the position of the first position indicator is detected, and continues both detecting the position of the second position indicator and detecting the position of the first position indicator after the state in which the positions of the first position indicator and the second position indicator are not detected changes to a state in which the position of the second position indicator is detected.
