DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the image forming apparatus of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the image forming apparatus,
FIG. 2 is a right side view of the image forming apparatus.

The image forming apparatus 1 has a lower main body 3 having a mechanism section 2 incorporated therein and an upper main body 5 having a mechanism section 4 incorporated therein. The mechanical section 2 of the lower main body 3 is mainly composed of a paper conveying device 7 for the transfer paper supplied from the paper feeding cassette 6, and the transfer paper taken out from the paper feeding cassette 6 is conveyed from the right side of the lower main body 3. The apparatus 7 conveys the sheet from the right side to the left side, and a sheet conveying path 8 is formed in the lateral direction.

The mechanical section 4 of the upper main body 5 is mainly composed of an image forming process apparatus 10 including a photoconductor 9.
The upper main body 5 is openable and closable with respect to the lower main body 3 with a support shaft 11 parallel to the paper transport path 8 as a fulcrum.
By opening the upper main body 5, the entire upper surface of the paper transport path 8 can be opened widely. The upper body 5 is set so that the opening angle α can be opened with respect to the lower body 3.

An original pressing cover 12 is provided on the upper body 5 and the original pressing cover 12 is attached to the upper main body 5.
With respect to the document holder 13 that can be opened and closed in the same direction as that of FIG.
A document 14 is placed on the document receiver 13. The document pressing cover 12 is set so that the opening angle β can be opened with respect to the upper main body 5.

The sum of the opening angle α of the upper body 5 with respect to the lower body 3 and the opening angle β of the document pressing cover 12 with respect to the upper body 5 is set to 90 degrees or less. Therefore,
For example, even if the original pressing cover 12 is opened to the upper main body 5 with the upper main body 5 being opened to the lower main body 3 for maintenance or the like, the original placed on the original receiver 13 is 14 does not drop on the side opposite to the opening direction of the document pressing cover 12 or turn up.

3 and 4 show another embodiment of the image forming apparatus of the present invention, FIG. 3 is a front view of the image forming apparatus, and FIG.
FIG. 3 is a right side view of the image forming apparatus.

The image forming apparatus 1 has a lower main body 3 containing the mechanism section 2 and an upper main body 5 containing the mechanism section 4, which are constructed in the same manner as in the above-mentioned embodiment. , And the description thereof will be omitted.

An automatic document feeder 20 is provided above the upper main body 5, and the automatic document feeder 20 can be opened and closed in the same direction with respect to the upper main body 5 and is set so as to open an opening angle β. ing. The sum of the opening angle α of the upper body 5 with respect to the lower body 3 and the opening angle β of the automatic document feeder 20 with respect to the upper body 5 is set to 90 degrees or less. Therefore, for example, for maintenance, the upper main body 5 is opened with respect to the lower main body 3, and the upper main body 5 is further opened.
However, even if the automatic document feeder 20 is opened, the device body is prevented from falling, and even if such a fall does not occur, the document 14 placed on the automatic document feeder 20 will be the automatic document. It is possible to prevent the document from falling or turning over on the side opposite to the opening direction of the feeding device 20.

[0022]

As described above, according to the invention of claim 1, the sum of the opening angle of the upper body with respect to the lower body and the opening angle of the document pressing cover with respect to the upper body is set to 90 degrees or less. For example, even when the upper body is opened with respect to the lower body for maintenance, the original holding cover may be opened further with respect to the upper main body. You can prevent it from falling on the side opposite to the opening direction and turning over.

According to the second aspect of the invention, the sum of the opening angle of the upper main body with respect to the lower main body and the opening angle of the automatic document feeder with respect to the upper main body is set to 90 degrees or less. , Even if the upper document is opened with respect to the lower body and the automatic document feeder may be opened with respect to the upper body, the device does not fall, and even if such a fall does not occur, automatic It is possible to prevent the document placed on the document feeding device from dropping or turning over on the side opposite to the opening direction of the automatic document feeding device.

According to the third aspect of the invention, since the upper body can be opened and closed with respect to the lower body with a support shaft parallel to the paper transport path as a fulcrum, the opening angle of the upper body with respect to the lower body can be set small. A large area above the entire surface of the paper transport path can be opened, and jam processing and the like can be easily performed.
