Abstract

A reading apparatus that performs colorimetry for an image on a sheet, includes a conveyor that conveys the sheet along a conveyance path; a first guide member that includes a reference surface arranged to face the conveyance path and to oppose the sheet and provided with an opening, and, guides the sheet; a first opposite member that urges the sheet toward the reference surface, and, brings the sheet in contact with the reference surface; a colorimetry unit that is disposed at a side opposite to the conveyance path so as to sandwich the first guide member, and, performs colorimetry for the image through the opening; and a processor that controls the conveyor and the first opposite member so as to convey the sheet in a state of being brought in contact with the reference surface, before the colorimetry unit performs colorimetry for the image.

CROSS-REFERENCE TO RELATED APPLICATION

[0001] The present application is a continuation of U.S. patent application Ser. No. 15 / 939,773, filed on Mar. 29, 2018, which claims priority to Japanese Patent Application No. 2017-067975 filed on Mar. 30, 2017, the entire contents of U.S. Ser. No. 15 / 939,773 and JP 2017-067975 are incorporated herein by reference.BACKGROUND1. Technical Field

[0002] The present invention relates to a reading apparatus, an image forming system, and a non-transitory computer-readable storage medium storing a control program.2. Description of Related Arts

[0003] In recent years, in the color printing industry, in place of conventional offset-printing apparatuses, image forming apparatuses, such as a printer of an electrophotographic system, have been utilized widely.

[0004] In such an image forming apparatus, in order to attain stabilization of image density, there is an image forming apparatus that disposes an optical sensor on a conveyance path of a sheet, detects a s...
