A conveying apparatus includes a rotator, a driver, a measuring device, and circuitry. The rotator is configured to convey a medium. The driver is configured to apply a driving force to the rotator to rotate the rotator. The measuring device is configured to measure the driving force applied to the rotator by the driver. The circuitry is configured to: determine, according to the driving force measured, whether to change at least one of frequency and items of information to be acquired for prediction of a defective conveyance of the medium caused by the rotator; and acquire information of at least one of the items according to a result of determination, at a frequency according to the result of determination.

Conveying apparatus, method for acquiring information, and non-transitory computer-readable recording medium

An image reading apparatus including a first image reader for reading the front side of document, and a second image reader configured to read the reverse side of document. The apparatus also includes a storage device to store first image data read by the first image reader and second image data read by the second image reader, and a writing controller for writing the first image data and the second image data in parallel to the storage device. A reading controller then reads the first image data and the second image data sequentially from the storage device, and an image processor processes the first and second image data. An image converter then converts the format of the first image data and/or the second image data to be the same.

Image reading apparatus

A level detecting part detects image data levels for the respective output directions of the first half and the second half to be used for the linearity correction, which image data levels correspond to image data around a connection point between the first half and the second half and are obtained from respective combinations for the respective output directions of the first half and the second half. A calculating part calculates linearity correction values or correction value calculating parameters from the detected image data levels for any one of the first half and the second half; and a defect detection part detecting a defect in the image data levels thus detected around the connection point are provided.
