Description

Image reading apparatus and image forming system Technical Field The present invention relates to an image reading apparatus and an image forming system. Background An image forming system or an image forming apparatus may include a color measuring unit for measuring a color of an image formed on a sheet of paper in order to adjust color characteristics of the image (see japanese patent application laid-open No. 2015-166822, etc.). In the image forming apparatus described in japanese patent application laid-open No. 2015-166822, a color measuring section is disposed downstream of a fixing section, and the color measuring section is configured to be changeable to a1 st posture parallel along a conveyance path for conveying a sheet on which an image is formed in a conveyance direction and a2 nd posture intersecting the conveyance path. In the image forming apparatus described in japanese patent application laid-open No. 2015-166822, the color measuring portion is not movable in the conveyance width direction orthogonal to the conveyance direction. Therefore, when images such as a plurality of patch images are formed on a sheet in the conveyance width direction, it is impossible to color any of the plurality of images by the color measuring section. On the other hand, although the color measuring section may be configured to be movable in the conveyance width direction to measure the color of any of the images, there is a possibility that the height position of the color measuring section with respect to the conveyance path during color measurement varies with the movement of the color measuring section in the conveyance width direction, resulting in a reduction in the color measurement accuracy of the color measuring section. Disclosure of Invention The present invention aims to provide an image reading device and an image forming system, which can improve the color measurement accuracy of a color measurement part even when the color measurement part is configured to be movable in a conveying width direction. In order to achieve at least one of the above objects, an image reading apparatus according to one aspect of the present invention includes: A conveyance path provided in the box-type apparatus main body and conveying the image-formed paper sheet in a conveyance direction; A support frame provided in the apparatus main body, arranged so as to overlap a part of the conveyance path in a plan view, and extending in a conveyance width direction orthogonal to the conveyance direction; a color measuring section provided on the support frame so as to be movable in the conveyance width direction and configured to measure a color of any one of a plurality of images formed on a sheet along the conveyance width direction, and And a driving unit provided on the support frame and configured to move the color measuring unit in the conveyance width direction.
