摘要： The movable stages carry chucks 10a and 10b and move towards secondary stage bases 11a and 11b and a primary stage base 11, thereby positioning the substrate 1 on the primary stage base 11. Each first laser length-measuring system includes laser sources 31a and 31b, bar mirrors 34a and 34b mounted below X stages 14 of the movable stages, and laser interferometers 32a and 32b disposed at positions deviated from X guide rails 13 on the primary stage base 11, so as to detect positions of the movable stages in X direction. The laser interferometers 32a and 32b will not be influenced by the vibration of the secondary stage bases 11a and 11b. Meanwhile, the measuring distance from the laser interferometers 32a and 32b to the movable stages on the primary stage base 11 is reduced.

摘要： An image forming apparatus is configured to discharge droplets onto a web to form an image. The image forming apparatus includes a conveyor, a web position detector, and control circuitry. The conveyor is configured to convey the web while applying a tension to the web. The web position detector is configured to detect a position of the web during conveyance. The control circuitry is configured to adjust landing positions of the droplets onto the web in a main scanning direction and a sub-scanning direction in accordance with the position of the web detected by the web position detector and control the tension applied to the web by the conveyor. The web position detector is configured to detect the position of the web in a cycle that is at least twice a tension control cycle in which the control circuitry controls a magnitude of the tension.
