摘要： An optical apparatus is disclosed which can suppress an increase in size thereof even if its lens is driven in a large movable range. The apparatus comprises a first linear actuator which includes a first member to which an electrical signal is input and a second member whose length in an optical axis direction is longer than the first member, and drives a first lens in a first movable range in the optical axis direction. The apparatus comprises a second linear actuator which includes a third member to which an electrical signal is input and a fourth member whose length in the optical axis direction is longer than the third member, and drives a second lens in a second movable range in the optical axis direction. The first member is moved together with the first lens in the optical axis direction, with respect to the second member.

摘要： Non-contact type displacement sensors which measure the height of a substrate surface are installed above the substrate in order to hold the upper surface of the substrate at a desired height or to maintain the flatness of the substrate. A substrate mounting device is such that a plurality of grooves and of barriers are provided on the upper surface of a table and air is supplied between the substrate and the table to enable the pressure of air to displace the substrate. In addition, the substrate mounting device has such a structure as to make it possible to deform the substrate into an arbitrary convex-concave shape or to make the substrate flat by feeding back the output of the displacement sensor.

摘要： An image forming apparatus includes a transfer unit that transfers a toner image on an image bearer onto a transfer medium. The image forming apparatus includes a control unit that controls a transfer voltage to be output to the transfer unit in accordance with a certain condition. The control unit applies currents having at least two different values while paper is not being fed. The two current values are lower than a current value during paper feeding. The control unit estimates an output voltage on a basis of a voltage detected through the application of the currents. When the estimated output voltage falls below a certain limiter voltage, the control unit controls to bring the output voltage to a value calculated through the certain condition. When the estimated output voltage exceeds the certain limiter voltage, the control unit controls to bring the output voltage to the limiter voltage.
