ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an image forming apparatus for which the installation space can be made small and which is good in original setting operability. Particularly, it relates to an image forming apparatus of which the space saving can be realized without spoiling the visual confirmability and the taking-out operability of a delivered sheet.
2. Related Background Art
As an image forming apparatus provided with an original image reading portion such as a copying machine or a facsimile apparatus, an apparatus of a type in which an image reading portion is disposed in the upper portion of the apparatus and an image forming portion is provided below it and recording sheets on which images have been formed by the image forming portion are delivered outwardly from a side of the apparatus and are stacked is popular.
In recent years, however, there is available an apparatus as shown in
FIG. 12
of the accompanying drawings wherein for the purpose of space saving, a space
103
is provided between an image reading portion
101
and an image forming portion
102
and recording sheets are delivered to and stacked in this space
103
.
In the image reading portion
101
, an original fed from an auto original feeder (hereinafter referred to as the “ADF”)
109
disposed in the upper portion thereof is exposed and scanned, whereby image information is taken into a photoelectric transfer element and data processing is effected.
On the basis of the data, a laser scanner
104
scans on a photosensitive drum
105
to thereby effect latent image formation. A toner image developed on the photosensitive drum
105
in accordance with the latent image is transferred onto a sheet fed from a feed cassette
106
, and passes through a fixing device
107
and is fixed on the sheet, which is then delivered to and stacked in the delivery space
103
by delivery rollers
108
.
When in the image forming apparatus, sheets on which images have been recorded are to be subjected to such post-treatment as punching treatment or stapling treatment, as shown in
FIG. 13
of the accompanying drawings, a sheet treating apparatus
110
is connected to a side of the main body of the apparatus, and the sheets are fed into this sheet treating apparatus
110
to thereby effect stapling treatment or the like.
However, when the sheet treating apparatus
110
is connected to a side of the apparatus, a wide installation space becomes necessary. If an attempt is made to make this space smaller, the structure of the apparatus will become complicated or the taking-out operability of the sheet will become bad.
SUMMARY OF THE INVENTION
The present invention has been made in view of the above-noted points and the object thereof is to provide an image forming apparatus of which the space saving can be realized without spoiling the visual confirmability and the taking-out operability of a delivered sheet.
A typical construction according to the present invention for achieving the above object has an image reading portion for reading an image, an image forming portion disposed below the image reading portion for forming an image on a sheet, and a sheet delivering portion provided above the image reading portion, and the image reading portion is provided with an original transporting portion for transporting an original, and an original pressing portion openable and closable upwardly relative to the original transporting portion and for pressing the original.
As described above, in the present invention, the original pressing portion is made openable and closable with the sheet delivering portion and the original transporting portion remain fixed above the image reading portion, and therefore the light-weight original pressing portion can be easily opened and closed.
