Patent ID: 8779402

Claim:
A target supply device, comprising: a target supply device body including a nozzle having a through-hole through which a target material is discharged; and a vibration device comprising a piezoelectric member, an elastic member, a regulating member, and a holding unit, the piezoelectric member being connected to the target supply device body and configured to vibrate in accordance with an externally supplied electric signal, the elastic member being connected to the piezoelectric member and configured to apply a pressure to the piezoelectric member so that the piezoelectric member pushes the target supply device body, the regulating member being connected to the elastic member, the holding unit being connected to the target supply device body and configured to hold the regulating member, and the vibration device being configured to control the pressure to be applied by the elastic member to the piezoelectric member by changing position of the regulating member held by the holding unit.
