PROBLEM TO BE SOLVED: To provide a stable touch switch function not to be influenced by surrounding environments by changing the oscillation condition of a self-exciting oscillation circuit by load capacity changed when a touch plate is touched with a hand. SOLUTION: In this handle touch detection method of a pachinko hitting machine, the oscillation condition (oscillation state) of the self-exciting oscillation circuit (10) connected to the touch plate (2) is changed by the fact that the touch plate (2) is touched with the hand and output signals (6) for indicating a touch state are obtained on the basis of the change.
