Drive device and spray device using said drive device

A drive device for spraying a material, comprising:

• a driver configured to spray a spray material;
• a detector configured to detect a moving body;
• and
• a controller configured to control the driver based on detection results of the detector, wherein
• the controller comprises a detection determiner configured to determine whether or not to capture detection signals from the detector,
• a high threshold that is initially set and a low threshold that is lower than the high threshold are switchably set in the detection determiner as thresholds for determining whether or not to capture the detection signals, and
• the controller is configured to:
• perform drive processing to drive the driver and drive cancellation processing to cancel driving of the driver;
• perform, when the detection determiner makes a capture determination to determine the capture of the detection signals before executing the drive processing, low-switching processing to switch the threshold of the detection determiner from the high threshold to the low threshold before start of the drive processing based on the determination results;
• and
• perform, when the detection determiner makes a capture determination after execution of the low-switching processing, the drive cancellation processing based on the determination results.
