Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a printer or a copying machine, and more particularly to a sheet discharge tray apparatus in an image forming apparatus which handles sheets of small size to large size.

[0002]

2. Description of the Related Art A discharge tray device in a conventional image forming apparatus such as a copying machine is capable of expanding and contracting in its discharge direction, and when handling a small size sheet, as shown in FIG. On the other hand, when the telescopic tray 2 is kept in a contracted state and a large size sheet is handled, the contraction tray 2 is extended from the tray body 1 as shown in FIG. As another conventional example, as shown in FIG. 3, a telescopic tray 2'is provided so as to be foldable with respect to a tray main body 1 ', and the telescopic tray 2'can be folded or overhanged depending on the size of paper.

[0003]

SUMMARY OF THE INVENTION The above-mentioned conventional paper discharge tray device is used when the large size paper is handled.
There is a problem that the installation area of the device is increased by the amount of extending or overhanging 2 '.

The present invention has been made in view of the above, and handles small-sized paper without increasing the size of the discharge tray device in the planar direction even when handling large-sized paper. An object of the present invention is to provide a paper discharge tray device in an image forming apparatus capable of accommodating sheets of small size to large size with an installation area of a certain size.

[0005]

In order to achieve the above-mentioned object, in the paper discharge tray device in the image forming apparatus according to the present invention, a rotary tray 13 is provided on the front end side of the tray body 10 attached to the paper discharge unit 12. The tray main body 10 is provided such that it can be rotated upward from the same plane as the tray main body 10, and the tip side of the tray main body 10 is opened in the state of being rotated upward, A vertical tray 17 for accommodating sheets falling from the tip of the main body 10 is provided.

[0006]

[Operation] When handling a small size sheet, the rotating tray 13 is rotated downward so that the upper surface of the rotating tray 13 is substantially aligned with the upper surface of the tray body 10. As a result, the small-sized sheet is discharged onto the upper surfaces of the tray body 10 and the rotating tray 13.
On the other hand, when handling a large size sheet, the rotating tray 13 is rotated upward. As a result, a large-sized sheet has a gap between it and the tip of the tray body 10, the sheet is ejected from there, and then is dropped and stored in the vertical tray 17.

[0007]

EXAMPLE An example of the present invention will be described with reference to FIGS. Reference numeral 10 in the drawing denotes a tray main body that is horizontally attached to the paper output unit 12 of the copying machine 11.
A rotary tray 13 is provided at the leading end of the tray 0 so as to be rotatable upward from the same plane as the tray body 10. The tips of the legs 14a and 14b provided on both sides of the rotating tray 13 are slidably engaged with the grooves 15 provided on both sides of the tray body 10, and the intermediate portions of the legs 14a and 14b are provided. And the ends of the tray body 10 on both sides of the link 16a,
The links 16a and 16b are connected by 16b.
The rotation tray 13 is rotated by the rotation and the tips of the legs 14a and 14b sliding in the groove 15. When the rotating tray 13 is rotated upward, there is a gap between the upper surface of the tray body 10 and the rotating tray 13 so that the tip side of the tray body 10 is opened.

A vertical tray 17 is provided below the tip of the tray body 10. The vertical tray 17 is made of wire, and the upper end of the vertical tray 17 is engaged with and suspended from a suspending tool 18 provided below the tip of the tray body 10. The size of the vertical tray 17 in the plane direction is the tray body 10
It is sized so as to cover the lower side of the rotating tray 13 that projects to the outside.

In the above structure, when handling a small size sheet, the rotating tray 13 is rotated downward so that the upper surface of the rotating tray 13 is aligned with the upper surface of the tray body 10. Copier 1 in this state
The small size paper discharged from the first paper discharge unit 12 is received by the discharge tray surface constituted by the tray body 10 and the rotating tray 13. On the other hand, when handling a large size sheet, the rotary tray 13 is rotated upward. As a result, the leading end side of the tray body 10 is opened, and the large-sized sheet discharged onto the tray body 10 is dropped from the leading end of the tray body 10 into the vertical tray 17 to be accommodated therein.

[0010]

According to the present invention, even when handling a large-sized sheet, the size of the discharge tray device in the plane direction does not increase, and the installation area is the size required when handling a small-sized sheet. Therefore, it is possible to accommodate sheets of small size to large size.
