Abstract
An ejection device capable of preventing a discharge part from contacting an object is provided. The ejection device has a discharge part, a light projecting part, a light receiving part and a controller. The discharge part discharges a droplet to an object. The light projecting part projects a light between the discharge part and the object to form a light path across the object, and the light receiving part receives the light projected by the light projecting part. The controller stops driving the discharge part when the light receiving part does not receive the light.
