1) After forming a copy image thereon, the paper is discharged to the paper discharge section Q. Further, Q41 is a casing that houses the image forming means Q8 and has a document table (24 m) on the upper surface, and is a supporting means, and has a paper feed section insertion opening (25a) and a sheet paper (21) discharge opening (25b). 1) Both sides and the bottom surface are supported by the support plate (c) formed with the support plate (c). Also, below both sides of the support plate (c) are first rails (
A) is formed, and a first roller (c) is supported by an arm (27a) and constitutes a sliding means together with the first rail (c) at the rear end of the first rail (a). It is provided. However, the first rail wing is formed to have a first stepped portion (26JI) that is lowered in a cam shape at its front end.

On the other hand, there are desk drawers for office use, etc. 28a), (28b)
) is formed on the upper surface of the upper drawer part (28C) of the desk (c) with a window part OI consisting of a notch of approximately the same size as the plane of the casing 241, and a window part OI is formed at the end of the cutout part (28C). A document cover (30a) is provided to cover the portion (to). Furthermore, there is a guide part on the inner wall of the drawer part (28C), and a first
A second rail ciυ and a second roller 02 that slide with the rail (c) and the first roller (27) are provided. That is, when storing the casing (goods) in the drawer part (28C), the first roller Q7) fits between the second rails Ctl1, and the second roller 07J fits between the first rails and the casing ( 24) is slid. However, the second rail 0υ
is formed to have a second stepped portion (aia) corresponding to the first rail (e) and raised in a cam shape at the rear end at the same height as the first stepped portion (26a). Note that (to) the handle of the support plate Q51 (C14) is a control panel.

However, when installing the image forming body 00 in the office,
Install the desk Q (to) on the seat of the person who will be the operator, insert the roller 0η of fJsl into the second rail 6υ of the upper drawer part (28C), and insert the second roller 02 into the first rail (ha). ) and insert the image forming body QO) into the desk Q@
The first rail (E) and the second rail (c31) are attached to the first step (2) to complete the installation.
6a) and the second step (31a),
When the housing Q4 is set all the way into the drawer part (28e),
Since the first roller (27) and the second roller c13 slide along the second step (31a) and the first step (26a), the case example slides as shown in FIG. It will be lifted 63 lengths higher than usual. As a result, the casing Q4 can be inserted into the drawer part (28G) without touching the front end of the top surface of the desk (c), while the document table (24a) on the top surface of the casing (c) is inserted into the window part (to) when set. When inserted, the document table (24a) and the top surface of the desk (c) are aligned at the same height, making it possible to copy from the top of the desk (28).

At the time of copying, the document cover (c) on the desk (c)

Meanwhile, a sheet of paper Qυ is fed from the paper feed section ■, and the sheet of paper (21) is further conveyed in synchronization with the toner image on the photoreceptor drum (11), and the copy image is completed through transfer and fixation. The paper is then ejected to the paper ejection section.Also, when performing maintenance etc., the drawer section (28C)
This can be easily done by pulling out the housing (2) further. Further, when not in use, the document cover (30a) is closed and the document table (24a) is covered.

With this configuration, there is no need for a dedicated space for installing a special cabinet for placing the image forming unit H, which saves space and makes it easy to install even in small offices. It is easily realized, and the temporary copying operator can move from the desk (mark 2) to the case (mark 2) while sitting.
You can make copies by placing the original on the window on the top of the desk (c) without having to pull out the desk (c), which improves its operability. It is also possible to hold the image forming body 0@ on the desk.

The present invention is not limited to the above-mentioned embodiments, but can be modified in various ways. For example, the structure of the guide section and slide means can be changed as desired. The housing can also be designed so that the storage time is 0η as shown in FIG.
The casing may be formed integrally with the supporting means so as to have a recess (38a) for avoiding the front end (37a) of the upper surface. Further, the position of the control panel, the shape of the paper ejection section, etc. are not limited. Furthermore, the document cover may also be provided with a bent portion so that only the control panel can be exposed during operation, or it may be of a type that is not fixed to the desk but is normally kept away and covers the document only during copying.

[Effects of the Invention] As explained above, according to the present invention, a miniaturized image forming apparatus can be stored in a drawer of an office desk, etc., thereby eliminating the need for a dedicated mounting stand such as a cabinet, etc. There is no need to provide a space for this purpose, saving space and making it possible to install an image forming apparatus even in a narrow space. Furthermore, a copy can be obtained by simply placing the original on the window formed on the desk without pulling out the copy temporary housing from the drawer, improving the operability. Furthermore, as in the embodiment, if both the paper feed section and the paper ejection section are provided on the handle side of the desk, operations such as starting copying or taking out the image support can be performed from the front of the desk. The operator can perform copying operations while sitting completely, which further improves operability.
