Description

TECHNICAL FIELD The present invention relates to an image forming apparatus in which an accessory unit is selectively attached to an outer wall portion of an image forming apparatus body.

2. Description of the Related Art Image forming apparatuses of the above type are known. As an example of an accessory unit in this type of image forming apparatus, there is an external paper feeding unit, a paper refeeding unit proposed by the applicant of the present application, which is not known.

By the way, there are times when it is necessary to move an image forming apparatus to which such an accessory unit is attached, for example, a copying machine. In this case, the accessory unit is removed from the main body of the copying machine and then moved, and after the move, the accessory unit is attached again. However, such an operation is very troublesome, and there is a problem that depending on the unit, the detaching operation must be requested to an expert or a specialist.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an image forming apparatus in which anyone can easily move even if an accessory unit is attached.

Constitution For the above-mentioned object, the present invention is an image forming apparatus in which an accessory unit is selectively attached to an outer wall of an image forming apparatus main body, is fixed to the image forming apparatus main body, and is attached to the attachment side of the main body. A guide rail having an approximately U-shaped cross section and a state fixed to the accessory unit and attached to the outer wall portion of the image forming apparatus main body,
The present invention is achieved by having a slide rail whose cross section that makes surface contact with the peripheral surface of the guide rail has a substantially U-shape.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is an image forming apparatus main body, 2 is an accessory unit selectively attached to an outer wall portion of the main body,
In the case of this example, the attached unit 2 is a re-feeding device. This re-feeding device can be
This is a device for stacking and feeding the sheets after the second copying, but a detailed description thereof is omitted because it is not the gist of the present invention.

In FIG. 3, an accessory unit 2 of the image forming apparatus main body 1
Guide rails 6 having a substantially U-shaped cross section extending to the attachment side of the accessory unit 2 are fixed to both ends of the outer wall portion to which the attachment is made by screws or the like. On the other hand, a slide rail 5 having a substantially U-shaped cross section is fixed to the attachment side of the accessory unit 2 so as to come into surface contact with the guide rail 6. The guide rail 6 is fixed when the accessory unit 2 is attached, and the tip of the guide rail 6 projects from the side surface of the image forming apparatus main body 1 in accordance with the sliding width. Then, when the accessory unit 2 is attached, as shown in FIG. 4, the slide rail 5 and the guide rail 6 are fitted together, and the accessory unit 2 is slidably attached to the image forming apparatus main body 1. By making the accessory unit 2 slidable with respect to the main body 1 of the image forming apparatus, it is possible to easily clean the components of the accessory unit 2 and remove jams in the accessory unit 2.

In the image forming apparatus thus configured, when the accessory unit 2 is attached to the image forming apparatus main body 1, the slide rail 5 and the guide rail 6 are brought into surface contact with each other and are connected to each other. A large mechanical strength can be obtained in the connection between the main body 1 and the accessory unit 2. In particular, if the slide rail 5 and the guide rail 6 are fitted so that the U-shapes thereof are opposite to each other, both rails 5 and 6 are constructed as one rail having a substantially track-shaped cross section, which is strong. The connection strength is obtained.

Thus, since the accessory unit 2 is connected to the image forming apparatus main body 1 with great strength, as shown in FIG.
Can be moved. At this time, the accessory unit 2 is moved by the height of the rubber feet 3 of the image forming apparatus main body 1 to the image forming apparatus main body 1
If a space l that can be accessed is formed between the mounting surface 4 of
It is easy to move with the accessory unit 2.

Effect The image forming apparatus according to the present invention is configured as described above, and since the accessory unit is connected by the double structure of the rail, a strong connection strength can be obtained, and the image forming apparatus holding the accessory unit by hand. It became possible to move.
