Abstract

PURPOSE:To prevent a paper jam caused by misoperation, by closing a paper discharge port by a discharge paper tray covering a starting key to inhibit its handling operation when the discharge paper tray of a picture forming device is closed to the main unit side. CONSTITUTION:A picture forming device 1 provides a discharge paper tray 2 in the opposite side to a feed paper tray 7 which inserts paper P, and the picture forming device 1, when it is not in use, turns the discharge paper tray 2 by a hinge mechanism 3 closing a paper discharge port 4. Simultaneously the picture forming device 1, coating also a starting key 5 with the discharge paper tray 2, inhibits starting. In this way, a paper jam, caused by misoperation, is prevented in the paper discharge port 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image forming apparatus that prevents paper jams from occurring due to a folded paper discharge tray.

[Prior Art] As shown in FIG. 1, conventionally, an image forming apparatus 1 forms an image on a paper P inside a main body 1 in response to a start signal from the outside and discharges the image onto a paper output tray 2 outside the main body 1. For example, electronic copying machines and printers. and image forming device 1
In order to reduce the size and make it easy to carry, the paper discharge tray 2 is often supported by a hinge 3 so as to be openable and closable relative to the image forming apparatus main body 1. In this case, as shown in FIG. 3, the paper ejection tray 2 blocks the ejection port 4 through which the paper is ejected.

[Problems to be Solved by the Invention] In the above configuration, when the paper ejection tray 2 is closed to the image forming apparatus main body 1 side, if a start signal is input by mistake, image formation is started, and the formed image is The paper with
The paper cannot be removed from the paper, resulting in a paper jam.

[Embodiment] As an embodiment of the present invention, a portable electronic copying machine with a fixed document table and a fixed reading device, which is one of the image forming apparatuses, will be described. FIGS. 1(a) and 1(b) are schematic explanatory diagrams. When the start key 5 is pressed, the document placed on the document table 6 is read by a reading mechanism (not shown), an image is formed on the paper P fed into the image forming apparatus 1 from the paper feed table 7, and the document is sent to the ejection port. The paper P is discharged from the paper discharge tray 2 from the paper discharge tray 2. The paper discharge tray 2 can be opened and closed with respect to the image forming apparatus 1 by means of a hinge 3.

The start key 5 is provided on the side discharge tray 2 side of the image forming apparatus 1. Therefore, the paper output tray 2 is connected to the image forming apparatus 1.
When closed to the side, the start key 5 is covered by the paper discharge tray 2.

Although an electronic copying machine has been taken up as one of the embodiments, other image forming apparatuses such as printers may also be used as long as they have a paper output tray that can be opened and closed on the main body and a start key that starts a series of image forming operations. I don't mind.

[Effects of the Invention] By configuring the main body to cover the start key when the openable paper ejection tray is closed, image formation cannot be started when the paper ejection tray is closed. , it is possible to prevent paper jams in the image forming apparatus.

[Brief explanation of the drawing]

FIGS. 1(a) and 1(b) are schematic illustrations of an embodiment of the present invention,
FIGS. 2 and 3 are illustrations of conventional examples. 1 is an image forming device, 2 is a paper output tray, 3 is a start key, 4
is the outlet and P is the paper.

Claims (1)

[Claims] This is an image forming apparatus that has a paper ejection tray that can be opened and closed from the main body, an ejection port that ejects paper, and a start key that starts a series of operations to form an image on paper and eject the paper from the ejection port. An image forming apparatus in which, when the paper tray is closed on the main body side, the paper ejection port is blocked by the paper ejection tray, and the paper ejection tray covers the start key, thereby prohibiting operation of the start key.
