The second image reading unit 170 is arranged in front of the operation unit 400 in the depth direction (Z-axis direction).

With this configuration, the document D whose image is read by the image reading section 160 and the second image reading section 170 is positioned in front of the operation section 400 in the depth direction (Z-axis direction). As a result, the document D ejected from the document ejection port 182 can be positioned in front of the operation unit 400 in the depth direction (Z-axis direction), and the operability of removing the ejected document can be improved. improves.

The image forming apparatus 1 includes an image reading section 160 and a second image reading section 170 for reading an image of a document being conveyed, and an operation section 400 for receiving an operation input to the image forming apparatus. A second image reading unit 170 is arranged below the operation unit 400 . With this configuration, the document D whose image is read by the image reading section 160 and the second image reading section 170 is positioned below the operation section 400 . As a result, the document D ejected from the document ejection port 182 can be positioned below the operation unit 400, thereby improving the operability when taking out the ejected document.

The document discharge section 180 is provided with a document discharge port 182 for discharging the document, and the sheet discharge section 80 is provided with a sheet discharge port 82 for discharging the sheet and a second sheet discharge port 92. A space that opens on one side and faces a document discharge port 182, a sheet discharge port 82, and a second sheet discharge port 92. A document discharged from the document discharge port 182 and a space and an ejection storage section 200 that accommodates the sheet and the sheet ejected from the second sheet ejection port 92 . As a result, the documents and sheets can be easily taken out from the image forming apparatus 1 while ensuring confidentiality of the discharged documents and sheets.
