摘要： A conveyance apparatus includes a liquid discharge head unit, a conveyance rotator, and a plurality of detection devices. The liquid discharge head unit discharge liquid to an object conveyed in a conveyance direction. The conveyance rotator conveys the object. The plurality of detection devices output a detection result indicating a position of the object. The adjacent two of the plurality of detection devices are spaced at a prescribed distance. The prescribed distance is an integral multiple of a circumference of the conveyance rotator.

摘要： A conveyance device includes a conveyor to convey a conveyed object, a head unit to perform an operation on the conveyed object being conveyed at a first conveyance speed, a sensor to acquire data of the conveyed object, a gauge to output a measured travel amount of the conveyed object, and a processor. The processor includes a calculator to calculate a detection result including at least one of a position, a speed of travel, and a calculated travel amount of the conveyed object based on the data acquired by the sensor; and an adjusting unit to adjust a timing of acquisition of the data acquired while the conveyed object is conveyed at the first conveyance speed, based on the detection result and the measured travel amount of the conveyed object being conveyed at a second conveyance speed lower than the first conveyance speed.
