Abstract

An image forming apparatus includes an image scanning section, an exit tray, and an upper housing. The image scanning section scans an image of an original document. The exit tray is disposed below the image scanning section. A sheet bearing an image is ejected onto the exit tray. The upper housing houses the image scanning section. The image forming apparatus has a sheet ejection space that is formed between the exit tray and the upper housing. A user's hand is inserted into the sheet ejection space for taking out the sheet from the exit tray. The upper housing includes a bottom plate having a surface that faces the exit tray. The bottom plate includes a plurality of reinforcing members that are disposed on the surface of the bottom plate and that extend in a direction in which the user takes out the recording medium from the exit tray.

First claim

What is claimed is:

1. An image forming apparatus that forms an image on a recording medium, comprising:
a scanner configured to scan an image of an original document;
an exit tray that is disposed below the scanner and onto which a recording medium bearing an image is ejected; and
a housing that houses the scanner, wherein
the image forming apparatus has a sheet ejection space that is formed between the exit tray and the housing and into which a user's hand is inserted for taking out the recording medium from the exit tray,
the housing includes a bottom plate having a surface that faces the exit tray, and the bottom plate includes a plurality of reinforcing members that are disposed on the surface of the bottom plate and that extend in a direction in which the user takes out the recording medium from the exit tray
the bottom plate of the housing has a curved portion having a smoothly curved surface concaved in a direction to expand the sheet ejection space and includes a guide section configured to guide linear movement of the scanner in a sub-scanning direction,
the reinforcing members each reinforce the bottom plate and are located on a lower surface of the curved portion of the bottom plate,
the guide section is curved such that the bottom plate protrudes upward,
the guide section is located substantially at a central part of the bottom plate in a direction in which the recording medium is taken out,
the reinforcing members and the curved portion are locate on a tip end side of the guide member in the direction in which the recording medium is taken out,
the reinforcing members are located a predetermined distance or more apart from the guide section,
the image forming apparatus further comprises an operation panel configured to receive user input for operation,
the operation panel is located along an upper surface of the bottom plate at a tip end part of the bottom plate in the direction in which the recording medium is taken out,
the reinforcing members each extend to a vicinity of the operation panel in the direction in which the recording medium is taken out to form a predetermined space on a side from which the recording medium is taken out, and
respective lowermost parts of the reinforcing members are substantially level with a lowermost part of the bottom plate located below the operation panel.

2. The image forming apparatus according to claim 1 , wherein
the reinforcing members are located in a region of the bottom plate that is opposite to the recording medium ejected on the exit tray.

3. The image forming apparatus according to claim 1 , wherein
the bottom plate of the housing has an arc shape in cross section.

4. The image forming apparatus according to claim 1 , wherein
the reinforcing members each have a semicircle shape in cross section.

5. The image forming apparatus according to claim 1 , wherein
the reinforcing members extend linearly in a direction in which the recording medium is taken out.

6. The image forming apparatus according to claim 1 , wherein
the exit tray has a first surface and a second surface, the first surface inclining at a first angle in the direction in which the recording medium is taken out relative to a horizontal plane, the second surface inclining at a second angle in the direction in which the recording medium is taken out relative to a horizontal plane,
the second angle is smaller than the first angle,
the second surface is located on a tip end side of the exit tray in which the recording medium is taken out relative to the first surface, and
the reinforcing members and the curved portion are located opposite to the second surface.
