Abstract: A position detection device for a horizontal articulated robot includes a camera for imaging the robot or a work as an imaging object, a control section for calculating a location of the imaging object from an image, an acquisition section (I/O) for obtaining the drive amounts of first and second electric motors of the robot, and a storage section for storing the calculated location of the imaging object and the drive amounts so as to correspond to each other. A common trigger signal for detecting the location of the imaging object is input to the camera and the I/O. The camera starts to image the imaging object in response to the input of the trigger signal. The I/O starts to obtain the drive amounts in response to the input of the trigger signal.

Abstract: Provided herein is a suction device having a plurality of head caps capable of closely contacting with and moving away from corresponding nozzle surfaces of a plurality of inkjet functional liquid droplet ejection heads. The suction device includes: a plurality of cap units having one or more of the head caps, a contacting/separating mechanism which makes the head caps contact and move away, a plurality of suction units which suck functional liquid from the head caps, a plurality of sets of suction channels each of which having a main channel and individual channels, and a plurality of channel switching units which selectively switch the suction channels to any one of the suction units.

Abstract: Provided herein is a suction device that is provided in an inkjet liquid droplet ejection apparatus and sucks functional liquid while contacting with nozzle surfaces of the functional liquid droplet ejection heads. The suction device has a plurality of head caps, a suction channel having a plurality of individual channels, a plurality of channel opening/closing unit that is disposed on the individual channels and opens and closes the respective individual channels, a waste liquid tank, an ejector, a pressure adjustment unit that adjusts pressure of the compressed air at the primary side of the ejector, and a control unit that controls the pressure adjustment unit. The control unit controls the pressure adjustment unit according to the number of open-channel opening/closing units opened out of the plurality of channel opening/closing units such that a suction pressure is constant in the plurality of head caps.
