Description

  The present invention relates to an image forming apparatus, and more particularly, to an image forming apparatus such as a copying machine, a facsimile machine, a printer, or a multi-function peripheral of these, which reads an original image, forms an image on a transfer medium, and discharges the image.

In a conventional image forming apparatus such as a copying machine, a facsimile machine, a printer, etc., without discharging the paper on which the image has been formed to the left and right side surfaces of the apparatus main body, that is, between the document image reading apparatus and the image forming unit, It is publicly known that paper is discharged into the body of the apparatus body to reduce the space occupied by the apparatus and save space (see Patent Document 1, Patent Document 2, Patent Document 3, etc.).
10 to 12, the transfer paper discharge space 103 formed between the image forming unit 102 below the original image reading apparatus 101 in the conventional image forming apparatus 100 is considered in consideration of operability for removing the transfer paper. Thus, the left front surface 100a ₁ of the illustrated apparatus main body 100a on the front surface 103b or the right front surface (not shown) is open. Accordingly, the document image reading apparatus 101 in the conventional image forming apparatus 100 is supported at three points.
If the front surface 103b side of the transfer paper discharge space 103 is thus opened, the front left side of the document image reading apparatus 101 is not supported as shown in the figure.

However, in the image forming apparatus that must support long paper as special paper in addition to the standard size, if a support member is provided on the side of the upper paper discharge device of the paper discharge device, the long paper will not fit in the cylinder, Can not be stacked due to interference with the support member.
For this reason, the upper discharge stacking member of the paper discharge device is supported by cantilever only on the back side, and depending on the stacking capacity of the upper discharge stacking member of the upper discharge device of the discharge device, The upper discharge stacking member of the upper discharge device of the paper device hangs down and the discharge quality deteriorates.
Accordingly, the conventional image forming apparatus saves space by reducing the occupation area of the apparatus by discharging the sheet between the document image reading apparatus and the image forming unit, that is, in the body of the apparatus main body, and transferring the image. Opening the left front or right front of the device main body to ensure the operability to remove the paper, the upper discharge stacking member prevents the original image reading device and the facsimile and copy paper that have already been sent from being mixed. Is lowered and twisted and deformed so that the original image cannot be read correctly, so that an abnormal image is output as a skew image.If a support member is provided, the long paper does not fit in the cylinder, There was a problem that the paper output quality was deteriorated such as tearing, folding, winding, etc. due to interference with loading.
