Therefore, even if the back cover 28 is opened with respect to the apparatus main body 12, the second posture (closed state) can be maintained. Therefore, after the back cover 28 is opened, the user opens the first medium support tray 30 in the second posture (closed). Operability is improved.

■■■ Regulation cover explanation ■■■■■■■
Referring to FIGS. 5A and 5B again, the restriction cover 60 includes protrusions 90 on the back surface of the scanner unit 14 and the side facing the ADF 16. The protrusion 90 is formed so as to protrude from the regulation cover 60 toward the back surface of the scanner unit 14 and the ADF 16 side.

  Further, a medium insertion port 62 for inserting a medium is formed between the first medium support tray 30 and the back surface of the scanner unit 14. The regulation cover 60 regulates the size of the medium insertion opening 62 in the Y-axis direction in FIG. 5A in the lying posture (see FIG. 5A), and the front opening 92 becomes larger than necessary. To prevent that.

  A medium insertion port 62 formed between the scanner unit 14 and the first medium support tray 30 is provided in the first medium support tray 30 and the scanner unit 14, and the scanner unit 14 and the first medium support tray 30. Therefore, it is possible to prevent the gap 92 between the first medium support tray 30 and the scanner unit 14 from becoming unnecessarily large, and foreign matter can enter the gap 92.
