The upper edge of the partition member 5 is rotatably mounted to a mounting shaft 6 provided above a paper delivery port 3 so as to extend to the paper delivery direction. In addition, a lock means 8 on which the partition member 5 is locked with the partition member 5 rotated upwardly at 90°, is provided. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a paper discharge device and an image forming apparatus.

  A partition member is provided at the center (widthwise center) of the output tray that is installed at the output port of image forming apparatuses such as copiers, printers, and facsimile machines, and small-size paper is placed on the left and right sides of the partition member. The present applicant has already proposed a paper discharge device having a parallel paper discharge sorting mechanism for discharging and sorting paper.

In the paper discharge device described above, when large-size paper is normally discharged onto the paper discharge tray without partitioning the paper discharge tray with the partition member, the partition member must be retracted from a predetermined position. For this purpose, a space for evacuation is required. Accordingly, there has been a problem that it is difficult to adopt in a small-sized image forming apparatus in which it is difficult to secure a retreat space.
Recently, in order to reduce the size, there is known a so-called in-body discharge mechanism that uses a space inside the main body to provide a discharge tray in the space to discharge the sheet.

  The present invention has been made in view of such a background, and provides a paper discharge device and an image forming apparatus capable of reducing a space for retracting partition members on the premise of employing a parallel paper discharge sorting mechanism. The purpose is to do.

  In order to achieve the above object, according to the first aspect of the present invention, a partition member is provided at a central portion in the width direction of a sheet discharge tray that receives a sheet discharged from the apparatus main body, and small size paper is placed on the left and right sides of the partition member. Is a paper discharge device that discharges and sorts the paper, and the upper side of the partition member is rotatably attached to a mounting shaft provided so as to extend in the paper discharge direction above the paper discharge port, and further the partition member rotates upward The most important feature is a paper discharge device provided with locking means that is locked in this state.

The invention of claim 2 is provided with an in-cylinder paper discharge structure having a paper discharge tray in the cylinder, a partition member is provided at the center in the width direction of the paper discharge tray, and small-size paper is placed on the left and right sides of the partition member. A paper discharge device that discharges and sorts the paper, and the upper side of the partition member is rotatably attached to an attachment shaft provided so as to extend in the paper discharge direction above the paper discharge port. It is characterized in that a locking means for locking this in a rotated state is provided.
An image forming apparatus according to a third aspect of the present invention is equipped with the paper discharge device according to the first or second aspect.

  The present invention is a paper discharge device that provides a partition member at the center in the width direction of the paper discharge tray, and discharges and sorts small-sized papers to the left and right across the partition member. Since the upper side of the partition member is rotatably attached to the mounting shaft provided so as to extend in the direction, and further provided with locking means that is locked in a state where the partition member is rotated 90 degrees upward, the partition member is retracted. Space can be reduced.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a paper discharge device according to an embodiment of the present invention, FIG. 2 is a view as viewed from A in FIG. 1, and FIG. 3 is a view as viewed from B in FIG.

  The paper discharge tray 1 is provided in the body of the image forming apparatus main body 10 (FIG. 2). The paper is discharged from a paper discharge port 3 formed on the main body wall surface (inner wall surface in the cylinder) 2. A pair of jogger fences 4 that can move left and right (inside and outside in the width direction) are provided at both ends in the width direction of the sheet discharge tray 1 located at the bottom of the cylinder, and a partition is formed at the center in the width direction of the sheet discharge tray 1. The member 5 is disposed. The partition member 5 is attached so that its upper side is rotatable in the direction of the arrow by an attachment shaft 6 fixed to the image forming apparatus main body 10 side. The attachment shaft 6 is provided above the paper discharge port 3 so as to extend in the paper discharge direction.

A bent portion 5-1 is formed at the bottom of the plate-like partition member 5 so as to hold one of the sheets to be partitioned. A pedestal 7 is provided at the center of the paper discharge tray 1 so that the discharged paper P is not frictionally adsorbed to the surface of the paper discharge tray.
When sorting the small-sized sheets P1 and P2, as shown in FIG. 1, for example, P1 is discharged to the right side (viewed from the B direction) of the partition member 5, and P2 is discharged to the left side. The discharged sheets P1 and P2 are aligned on the partition member 5 side by the jogger fence 4. Here, when the partition member 5 is rotated 90 degrees counterclockwise, the paper P1 is picked up by the bent portion 5-1, dropped onto the paper P2, and stacked.

  Locking claws 8 are provided on the ceiling portion in the body of the image forming apparatus main body 10, and as shown in FIGS. 2 and 3, the bent portion is bent when the partition member 5 rotates 180 degrees counterclockwise. Lock with 5-1. When the partition member 5 is retracted during normal paper discharge, the partition member 5 may be locked and fixed above the paper discharge port 3 by the locking claw 8. In the case of the in-body discharge mechanism, since there is a sufficient space above the discharge tray 1, it is not necessary to provide a special retreat space for the partition member 5.

1 is a perspective view of a paper discharge device according to an embodiment of the present invention. It is A view of FIG. It is a B view of FIG.
