The display unit 72 in this embodiment uses a color liquid crystal display device 75 having horizontal 320 dots and vertical 240 dots. Further, in order to display various information in an easy-to-see manner, white backlight illumination is performed from the back surface of the color liquid crystal display device 75, and a cold cathode tube is used as the illumination means.
A high voltage is temporarily required to light the cold cathode tube. From the viewpoint of safety, it is desirable that the substrate for generating this high voltage is housed inside the rotatable display unit 72 described above. Therefore, in this embodiment, the high voltage substrate 76 is arranged on the back surface of the display unit 72.

An electronic element having a height is mounted on the high-voltage board 76, so that the rear surface of the display section is a convex section 81 having a convex cross section. This convex shape is configured to be narrower than the display section 72 from the viewpoint of design, and is designed so that the convex section 81 is hard to notice when viewed from the front of the device.

On the other hand, the printer cover 17 has a concave concave portion 82 into which at least a part of the display portion 72, which is the convex portion 81 on the rear surface of the display portion in this embodiment, can enter.
Is provided. For this reason, for example, when packing or when the original is not conveyed, as shown in FIG.
By rotating the display unit 72 so as to enter the display unit 72, it is possible to set the display unit 72 to a position in which the display unit 72 is further laid down than the most laid state (hereinafter, referred to as “third position”).

By doing so, as shown in FIG. 4, the height from the floor surface to the display portion 72 is lowered to a height close to the tray height when the movable tray 11 supporting the recording sheet is in the lowest position. It will be possible. FIG. 3 shows a product perspective view in this state. As a result, it is possible to reduce the dead space in the packed state and to reduce the packing size.

The printer cover 17 also serves as a guide surface for conveying the original, and as shown in FIGS. 2 and 3, the recess 82 of the printer cover 17 affects the separating performance outside the rotation area of the display 72. It has a linear cross-section so that there is no

Further, the document auxiliary tray 18 can be attached to the concave portion 82 of the printer cover 17, and the cross section position of the document auxiliary tray 18 is arranged so as to be flush with the cross section outside the display portion of the printer cover. There is. Further, the original slider 15 for conveying the original straightly is provided with a printer cover 17 so that even a narrow original can be surely guided.
