摘要： A movable diffraction element and a spectroscope. The movable diffraction element includes a movable component having a comb-like shape, a supporting unit configured to support the movable component, a first cantilever actuator coupled to the supporting unit, a displacement determiner coupled to an edge of the first cantilever actuator, and a second cantilever actuator disposed parallel to the first cantilever actuator. In the movable diffraction element, a slope generated when the second cantilever actuator deforms is approximately equivalent to a slope generated at the first cantilever actuator. The spectroscope includes the movable diffraction element.

摘要： In an image forming apparatus, a distance adjusting unit adjusts an inter-unit distance between a contact unit and an image carrier by moving the image carrier or the contact unit by applying an opposing force to the image carrier or the contact unit against a biasing force applied by a biasing unit based on thickness information of a recording sheet acquired by a thickness-information acquiring unit and data indicating a relationship between the thickness information and an inter-unit distance change amount stored in a data storage unit.

摘要： A fluctuation detecting unit detects a fluctuation of an endless belt generated when a sheet is brought into contact with a predetermined position of the endless belt at an upstream side in a conveying direction from a nip portion based on fluctuation information acquired by a fluctuation information acquiring unit. An entry timing estimating unit estimates entry timing of the sheet into the nip portion based on a detection of the fluctuation. A correction control unit corrects a speed fluctuation of the endless belt generated when the sheet enters the nip portion by performing a feedforward control of a first driving unit based on the entry timing.
