The present application is based on, and claims priority from JP Application Serial Number 2019-058698, filed Mar. 26, 2019, the disclosure of which is hereby incorporated by reference herein in its entirety.

BACKGROUND

1. Technical Field

The present disclosure relates to a medium transport apparatus that transports a medium, and an image reading apparatus including the medium transport apparatus.

2. Related Art

Some scanners, which are examples of image reading apparatuses, automatically feed a plurality of media toward a reading portion by a medium transport apparatus and perform reading by the reading portion. As an example, JP-T-2009-527143 discloses a scanner including a reading portion that reads a medium transported by a medium transport apparatus. The medium transport apparatus may be provided in a recording apparatus including a recording portion that performs recording on a medium, that is, the recording apparatus may be configured to send a plurality of media toward the recording portion by the medium transport apparatus.

In some cases, an image reading apparatus or a recording apparatus including a medium transport apparatus is installed on a desk or a shelf. At this time, in order to change the installation position of the apparatus, the apparatus may be dragged to move on the installation surface of the desk or shelf, but such movement may damage the installation surface. If the entire apparatus is completely lifted and moved, the installation surface will not be damaged, but many image reading apparatuses and recording apparatuses are relatively heavy even if the apparatuses are small, and moving by lifting the apparatuses is not easy.

SUMMARY

According to an aspect of the present disclosure, there is provided a medium transport apparatus including a transport unit that is provided in a transport path along which a medium is transported, and a processing portion that performs predetermined processing on the medium transported along the transport path, and the medium transport apparatus includes a rotating body at a bottom portion of an apparatus main body provided with the transport unit and the processing portion therein and the medium transport apparatus is configured to be switchable between a movable state in which the rotating body contacts an installation surface on which the apparatus main body is installed and the apparatus main body is movable on the installation surface with the rotation of the rotating body and an installation state in which a contact area of the bottom portion with respect to the installation surface is larger than the movable state and the apparatus main body is installed on the installation surface to be used.
