Description

The present application is based on, and claims priority from JP Application Serial Number 2021-194030, filed November 30, 2021. BACKGROUND 1. Technical Field The present disclosure relates to an image reading apparatus and a recording apparatus including a scanner unit and a document feed unit provided above the scanner unit and having a document reading section. 2. Related Art JP-A-2002-199156 can be raised as an example of such an image reading apparatus. A further example of an image reading apparatus is described in EP 3 310 031. JP-A-2002-199156 discloses an image reading apparatus comprising a first control substrate connected to a first optical reading device in an upper unit and a second control substrate connected to a second optical reading device in a lower unit. The first optical reading device, which is an image sensor disposed in an ADF unit, which is the upper unit, reads one side of a document and sends it to the first control substrate, which is a control device in the ADF unit. After performing predetermined image processing, and it transmits it to the lower unit side. On the other hand, the other side of the document is read by a second optical reading device, which is an image sensor disposed inside of the lower unit. And the second control substrate, which is the control device in the lower unit, processes image data of both front and back surfaces of the document received from the first control substrate and the second optical reading device and transmits it to an external image forming apparatus or the like. In the image reading apparatus disclosed in JP-A-2002-199156, as described above, the first control substrate configured to receive the image data from the first optical reading device is disposed in the ADF unit constituting the upper unit. On the other hand, a second control substrate configured to receive the image data from the second optical reading device is disposed in the lower unit. That is, the first control substrate and the second control substrate are disposed in the upper unit and the lower unit, separately. Therefore, it is necessary to secure space for disposing each control substrate in each of the upper unit and the lower unit, and there is a concern that this might lead to an increase in the size of the apparatus. SUMMARY In order to solve the above problems, an image reading apparatus is provided according to the appended set of claims. Further, a recording apparatus according to the present disclosure includes above mentioned image reading apparatus and a recording unit configured to execute recording process based on data read by the image reading apparatus.
