Abstract
In a touch detection apparatus, the controllerpredicts damper-on arrival time as time of arrival of generation of a damper-on event based on a period of time counted by a first counterfrom when a second contact pointis turned off until when a first contact pointis turned off. The second countercounts time to be compared to the damper-on arrival time. The comparator circuitcompares the time counted by the second counterand the damper-on arrival time. If the time counted by the second counterand the damper-on arrival time agree with each other, the comparator circuittransmits a key release agreement signal triggering generation of a damper-on event to the controller. If the key release agreement signal is transmitted from the comparator circuit, the controllerexecutes control to generate a damper-on event.
