Abstract

An image forming apparatus includes a protruding tray part. The protruding tray part is provided on the upper surface portion of a body casing part, extends in a paper discharge direction and has a convex shape which becomes convex at an upper side, and supports a part of a lower surface of a paper, which is discharged from a paper discharge port, from below, thereby forming a space between end portions of the paper and the upper surface portion of the body casing part. The paper conveying device is formed at a lower surface thereof with a guide recessed part. The guide recessed part has a concave shape corresponding to the convex shape of the protruding tray part, and is engaged with the convex shape to guide the paper conveying device when the paper conveying device is mounted in the in-body paper discharge space.

First claim

What is claimed is:

1 . An image forming apparatus comprising:
a body casing part that accommodates an image forming unit which performs an image forming process on a paper; a scanner casing part provided above the body casing part and accommodating an image reading unit; a connection casing part having a paper discharge port for discharging the paper subjected to the image forming process and connecting the body casing part to the scanner casing part; and an in-body paper discharge space surrounded by a wall part formed with the paper discharge port in the connection casing part, an upper surface portion of the body casing part, and a bottom surface portion of the scanner casing part, wherein the in-body paper discharge space is configured such that a paper conveying device is attachable and detachable, and the image forming apparatus further comprises: a protruding tray part provided on the upper surface portion of the body casing part, extending in a paper discharge direction and having a convex shape projecting upward when viewed from the paper discharge direction, and supporting a part of a lower surface of the paper, which is discharged from the paper discharge port, from below, thereby forming a space between end portions of the paper and the upper surface portion of the body casing part, wherein the paper conveying device is formed at a lower surface thereof with a guide recessed part which has a concave shape corresponding to the convex shape of the protruding tray part, and is engaged with the protruding tray part to guide the paper conveying device when the paper conveying device is mounted in the in-body paper discharge space.

2 . The image forming apparatus of claim 1 , wherein the paper conveying device is inserted into the in-body paper discharge space along the paper discharge direction from an outer side of the in-body paper discharge space, and
a front end portion of the guide recessed part in a device insertion direction is provided with an inclination surface inclined downward toward a front side in the device insertion direction.

3 . The image forming apparatus of claim 2 , wherein an electrical connector is exposed from a front surface of the paper conveying device in the device insertion direction,
a supply-side electrical connector fitted into the electrical connector of the paper conveying device to supply the electrical connector with power is exposed to a surface part of the connection casing part, which faces the in-body paper discharge space, and the guide recessed part is formed so as to guide the paper conveying device such that the electrical connector of the paper conveying device is fitted into the supply-side electrical connector.

4 . The image forming apparatus of claim 1 , wherein the protruding tray part is attachable and detachable from an upper surface of the body casing part.
