EXTERNAL-FORCE DETECTING APPARATUS AND METHOD OF DETECTING LINE BREAK |
摘要 |
An external-force detecting apparatus includes at least one drive line connecting the corresponding drive electrodes to a driving unit and at least one monitor line connecting the corresponding monitor electrodes to the driving unit. The driving unit outputs a drive signal to the at least one of the drive electrodes through the at least one of the drive lines to drive an oscillator and performs automatic gain control to the level of the drive signal based on the oscillation state of the oscillator acquired from the at least one of the monitor electrodes through the at least one of the monitor lines. The external-force detecting apparatus further includes a switching circuit arranged to switch between connection and disconnection of an electric path between the oscillator and the driving unit via at least one of the drive lines or the multiple monitor lines
